The original post was NOT about the validity of HTML Email in the world, but
about the specific code. The reality is that I don't like <BLINK>blinking
text</BLINK>, and will ALWAYS advise my clients against it, but if they WANT
it, then I give it to them... it's their money, their site.

Subsequently, if my client wants HTML email, and they aren't swayed by
advice to the contrary, then I have to deliver it, and deliver it within a
sufficient timeframe, with minimal bugs and hiccups.

Hence I (he/she) need to know how it's done.

Anyway, regardless of the above, the following was a bit odd:

Following this same logic, should we all just use <PRE> formatted green text
on a black background?

If formatting doesn't add anything, and if pretty colours make things harder
to read, and plain text-isms like *emphasis* are okay, then why have you
bothered to learn HTML to a "high standard", and chosen to use colors, bold
text, and other *simple* GUI tricks on your own webpage?

Perhaps the web was perfected at HTML2.0?

Things need to move forward, rather than staying in the archaic past.
Formatted emails are a natural progression of their plain-text ancestors...
in addition to simple GUI and useability benefits, they can also subtly add
value to an email in the areas of branding.

Bad HTML email has the same problem as bad HTML on the web -- written
poorly. It's not HTML's fault, or HTML email's fault, it's the bad
writer/designer.

Also, MANY people offering HTML-formatted email also offer the option of
plain text -- it's not like it's being force-fed to every user.

FWIW: I don't send in HTML, I don't like reading HTML email, I don't run any
mailing lists that use HTML mail. The issue isn't about my preferences,
it's about logic. There is a place for HTML email, in the hands of the
right people.

If your pointy-haired-boss or equally clue-challenged client *INSISTS* on
HTML email, then you clearly haven't explained to them:

Many of your recipients will delete it without reading.

But, if they still insist on it, one answer, as I already said, lies here:

http://phpclasses.org/

I'm sure there are a zillion other solutions, that just happens to be one I
know of.

Why it takes a few thousand people on this list to search this out for you,
when it's readily find-able in Google, or at least in a very brief search
starting at http://php.net/links.php is also beyond my comprehension.

Actually, though, when my clients insist on HTML email, I just tell them:
"No. If you want that feature, you'll have to hire somebody else to do it.
I've already explained why." I don't think I've lost a single client that
way -- Every one of them has re-considered my advice, and outright refusal,
and decided maybe I *do* know what the hell I'm talking about. YMMV.

Following your logic, should we install HUDs (Heads Up Display) *right*
*now* in cars rolling off the manufacturing line of Detroit?

No, of course not.

Your average driver isn't trained to use them, and probably won't be trained
to use them in any reasonable time frame.

Similarly, your average email client, and average email user, are clearly
*NOT* ready for HTML email. You only have to look at the spread of stupid
email viruses to understand this *FACT*.

Maybe, some day, with some reasonable effort on the part of an
organization/company that actually understands email, HTML and *SECURITY*,
there might actually *BE* a decent email client that can handle HTML-email,
and we might even have an "information superhighway" (LOL) capable of
handling the load that imposes across the board. Today is not that day.

A web-page is *NOT* an email.

More importantly, an email is *NOT* a web-page.

If you want me to look at your damn pretty colors and junky graphics, send
me an email with the link.

If I want to waste my time downloading all that crap, I'll click. If not,
buh-bye.

If you want to insist on sending me inappropriate content for the selected
medium, you'll get what you deserve -- I will delete your email without even
looking at it, much less with a chance that I'll be interested enough to
visit your web-site. I am not alone in this behaviour.

Actually I enjoy my Outlook Express...

"MIME-Version: 1.0\r\n" ."Content-type: text/html; charset=iso-8859-1\r\n"

Is all that I add other than the default headers of From: and Reply (after the MIME ...) and it works for me.

I'm running Outlook Express and that works perfectly.

We were all trained to cook in microwaves pretty quick smart -- an extremely different way of cooking. Not quite the same as a plain formatted email and one with a little bit of layout, clarity and visual hierarchy.

Yup -- couldn't agree more.

Agree totally.

Correct. An email is a communication medium. And long term, people are going to expect that email can have simular simple visual cues, formatting and layout that they can achieve as "second nature" in such shite as M$ Word.

Okay, I agree with all this, but there's definitely a mix-up here: *I* don't want to send HTML email. I hate it, never send it, don't like receiving it, don't run any lists that support it, and always attempt to subscribe to mailing lists as a text-only reader.

However, I do believe HTML mail (or *some* form of formatting) has a place, and in the right hands (impossible, I know), can be useful with minimal burden, and the original poster was well within their rights to ask how it was done, because realistically, they may have to achieve it. It's not truly you place or mine to dictate to them how evil it is -- just warn them as much as possible.

I have a form and I cannot figure out why this is not working. Not getting any error messages, I am just not getting the e-mail to show the form was filled out. Here it is, any help much appreciated, thanks <? $MailToAddress = "myemailhere.com"; $MailSubject = "Group volunteer list"; if (!$MailFromAddress) { $MailFromAddress = "$email"; } $Header = ""; $Footer = ""; ?> <? if (!is_array($HTTP_POST_VARS)) return; reset($HTTP_POST_VARS); while(list($key, $val) = each($HTTP_POST_VARS)) { $GLOBALS[$key] = $val; $val=stripslashes($val); $Message .= "$key = $val\n"; } if ($Header) { $Message = $Header."\n\n".$Message; } if ($Footer) { $Message .= "\n\n".$Footer; } mail( "$MailToAddress", "$MailSubject", "$Message", "From: $MailFromAddress"); ?>

attached mail follows:

What version of PHP are you running? If it's >= 4.1, then you should be using the $_POST array for the post vars.

It looks to me that you're just trying to loop through the POSTed vars, and print them as the message... if so, try something like this:

<? $MailToAddress = "myemailhere.com"; $MailSubject = "Group volunteer list"; if (!$MailFromAddress) { $MailFromAddress = "$email"; } $Header = ""; $Footer = "";

foreach($_POST as $key => $val) { $val = stripslashes($val); $Message .= "$key = $val\n"; }

if ($Header) { $Message = $Header."\n\n".$Message; }

if ($Footer) { $Message .= "\n\n".$Footer; }

mail($MailToAddress, $MailSubject, $Message, "From: {$MailFromAddress}"); ?>

Untested code of course :)

1. I'm not really sure why you were testing if HTTP_POST_VARS *wasn't* an array (pretty sure it's always an array)

2. I'm not really sure what you were doing with $GLOBALS, but the above should achieve what you want.

3. In the mail() (and in most of PHP) you don't need to put double quotes around $vars... only $vars within strings... and it also helps to wrap $vars within strings inside {curly braces} eg "From: {$MailFromAddress}"

This should probably be:

if (!isset($MailFromAddress) || !$MailFromAddress)){

Hard to tell if this is cut out from a bigger script or what...

You also have a very unusual (but at least consistent) indenting style for { and }...

> $MailFromAddress = "$email"; > } >$Header = ""; >$Footer = ""; >?> > > > <? > if (!is_array($HTTP_POST_VARS)) > return;

You may want to use isset() first here as well, and to check for the new $_POST array.

>reset($HTTP_POST_VARS); > while(list($key, $val) = each($HTTP_POST_VARS)) { > $GLOBALS[$key] = $val;

It would be better to use $$key = $val instead of stuffing things into $GLOBALS.

Variable variables are a documented feature. Assigning stuff into $GLOBALS is not. Don't think it will ever really break, but it's always safer to use documented features.

> $val=stripslashes($val); > > $Message .= "$key = $val\n";

To be strictly RFC-compliant, use \r\n, not just \n

> } > > if ($Header) { > $Message = $Header."\n\n".$Message; > } > > if ($Footer) { > $Message .= "\n\n".$Footer; > } > >mail( "$MailToAddress", "$MailSubject", "$Message", "From: >$MailFromAddress");

The quotes on the first three arguments are silly -- not harmful, just silly. You're forcing PHP to create another string to hold the strings you already have. A trifle wasteful, I suppose, but mostly just silly.

Also use Reply-to: as well as From: if you want maximum number of email clients to do the right thing.

You should be getting and checking the return value of the mail() function:

$success = mail($MailToAddress, $MailSubject, $Message, "From: $MailFromAddress\r\nReply-to: $MailFromAddress); if ($success){ echo "Mail successfully queued.<BR>\n"; } else{ echo "Unable to queue email.<BR>\n"; }

This last part may not help you figure out *WHY* the email isn't arriving, but you can at least pin-point the problem to either *BEFORE* PHP ever gets the email shoved into sendmail's queue, or after sendmail got the email.

If this prints "Unable to queue email" you know PHP is not talking nice enough to sendmail to get the email into sendmail's queue. If it claims the email was queued, you need to look at sendmail and see why it has decided not to send the email after all.

Hello,

there is a problem in a enterprise LAN: On each PC runs a Client, which waits at a haven for messages. With fsockopen(); messages are sent to all existing Clients. Functioned only, if one knows, the which Clients are switched on. If the Script meets a IP, whose PC is switched off, it dies. All following IP's receives no more message.

My problem: How can I receive a list of the PC's switched on at present with PHP? System calls are not a genuine solution. The Script is not only to work under Linux.

Thank you for your assistance

I don't think fsockopen's failure to open a socket will "kill" a PHP script...

Show us source code for that bit, and the loop you use to visit all the PC's...

Also be sure you are setting a reasonable time-out on the fsockopen (http://php.net/fsockopen) as well as on PHP itself (http://php.net/set_time_limit)

Try adding as much error-checking code as you can around the fsockopen functions calls, and log the stuff to a file or something where you can get it. http://php.net/error_log

With PHP 4.2, you don't have to use session_register. You can do it exactly like the OP is. I do it all the time. Whether that is a "feature" or a bug, I don't know.

It happens to work because that happens to be how Sessions are implemented this week.

Programming 101: Rule #27: Relying on implementation minutia instead of documented functions is just a Bad Idea (tm).

Use the functions that are documented to work. Anything else is a HACK and subject to break without notice.

In PHP 4.3 or 5.0 or 7.3.1, when it *DOESN'T* work anymore and you have a zillion lines of code cramming junk into $_SESSION scattered all through your application, don't come crying to me. :-)

Always a good method to follow, but the manual says you can use the $_SESSION method I gave. There is no need to use session_register() or the like. I would imagine that the older method would be depreciated eventually. It's a whole lot easier to just treat sessions like a variable without that whole register/unregister stuff.

The manual actually cautions against using session_register/unregister if register_globals is OFF.

mod_rewrite Rule #1.

Use that EngineLog or whatever it is to crank up your logging of mod_rewrite as high as it will go. Never mind the warning in the Apache manual about dire consequences to performance right now -- You'll *NEVER* intuit what the hell mod_rewrite is doing without that log. Trust me on this one :-) Lost a lot of hair before I got brave enough to ignore that particular warning in the manual. EXCEPTION: You're *not* doing this to a *LIVE* *PRODUCTION* server, right?!!!

Don't know squat about the mod_vhost_alias, or how it might be involved with the rewrite bit.

You are reading everything you can find about these at http://apache.org, right? Very nice web-site, once you figure out the format of the documentation. If your head is spinning, study the documentation on the simplist directive you think you *completely* understand, and then work with one that you think you understand that's a bit more similar to the one that's giving you problems, and then go back to your problem directive... Seeing the documentation "in context" with other directives often makes clear a single line that otherwise is just gibberish :-) YMMV.

Of course. Name your select box as an array, and include the 'multiple' keyword.

Then you'll have an array on your processing page that holds all of the values that were selected. $_POST['something'][]. Note that it starts at zero.

You can use count($_POST['something']) to see how many were selected, etc...

If you need specific IDs or something from the OPTIONs presented, other than the text between the tags, you can even use the VALUE= attribute to pass around data so that $_POST['something'] doesn't just start at 0 and count up:

<?php while (list($id, $name) = each($ineeddatacaptain)){ echo "$id: $name<BR>\n"; } ?> <SELECT NAME=ineeddatacaptain[] MULTIPLE SIZE=5> <OPTION VALUE=1>Captain Kirk</OPTION> <OPTION VALUE=2>Spock</OPTION> <OPTION VALUE=3>McCoy</OPTION> <OPTION VALUE=4>Scotty</OPTION> <OPTION VALUE=5>Sulu</OPTION> <OPTION VALUE=6>Uhura</OPTION> <OPTION VALUE=7>Chekov</OPTION> </SELECT>

If you click on Spock, instead of just 0, Spock, you'll get 2, Spock -- You get his ID number as well as his name.

This is extremely convenient. And you sure can't do that in ASP easily :-)

That's confusing. There's no way to get "Spock" from the code. You only
get the number in the value attribute. If the user were to choose Spock
and McCoy, then you'd have:
$_POST['ineeddatacaptain'][0] --> 2
$_POST['ineeddatacaptain'][1] --> 4
It's up to the programmer to associate 2 with Spock, and 4 with McCoy.

You should also do "ld_config" I think...

I do that any time I muck with /etc/ld.so.conf

>> >> Compiled PHP4 as follows: >> ./configure --enable-track-vars --with-gettext --enable-force-cgi-redirect >> --with-apache=../apache_1.3.26 --without-mysql >> --with-pgsql=/usr/local/pgql >> >> PHP code is working with Apache because other things work. Just that >> pg_connect() is always 'unknown function'.

Aha!

That means that even though you *ASKED* configure to give you --with-pgsql=/usr/local/pgql it didn't work. ./configure was able to stumble through, but it did give you a warning message about it, somewhere in that mass that scrolled by.

You could look in config.log, only it doesn't contain the "Yes/No" and other error output, so it only shows that ./configure *tried* to get PostgreSQL, not what actually happened. (Grrrrr.)

You could try reading config.cache, if your brain is twisted enough. Mine isn't. :-(

Re-do the ./configure, only this time like this:

./configure ... 2>&1 > configure.output &

Or is that '2&>1' ? I never really did grok the combination of > with & and how it turns into "shove stderr output in with stdout"...

Then, you can use: tail -f configure.output to examine configure.output as it is happening, but also use vi or less or grep to look at it again later. Don't ask me why ./configure itself doesn't give you the info you need in config.log -- I sure don't understand it.

Anyway, for some reason, PostgreSQL never got compiled into PHP, which is why there is no function named "pg_connect"

First Guess: /usr/local/pgql should be /usr/local/pgsql or /usr/local/psql or something other than /usr/local/pgql

Also don't ask me to explain why configure would just continue on and not give a fatal error when it can't give you what you asked for... As near as I can figure, if what you asked for is what it would have done by default, but it still can't do it, it will just keep going... That's pretty silly, if you ask me.

Ben, I have a system with lots of different types of reports. Like you I decided I didn't want to use the browser to print. Looked at PDF, RTF. I liked the printer functions, but they only worked on M$. After looking at all the alternatives I ended up going back to the browser for several reasons: It works on all the browsers, It's code you already know, it's fast. But I looked into the printer problem, not as a report, but as a system. And I developed a printer file system. When a user prints a report, it is run on the server side, so it is very fast. The output is put into the printer DB file, and an entry is made in the users IN BASKET. When they bring up the printer system it list all the reports in the IN BASKET. I have the alphabet across the top so they can go to any folder beginning with that letter, or use a folder field to list all the reports in that folder. When someone deletes a report from a folder it is sent to the WASTE BASKET folder, and stays there for 10 days before disappearing. So they have 10 days to get it out of the WASTE BASKET and file it back into another folder. There is a drop-down list of users the person may send the report to. If the user sends the report to 10 people for example, then they all get it in their IN BASKET, but only one detail of the report is on file. A lot of other stuff is on the list, like the date printed, title, who sent it, and a comment. The user can create other folders, for example a folder for WEEKLY COST and file, or move the data from the IN BASKET. If they they want to see the detail they can bring up as many pages as they wish (default is 5). They can ask for specific pages and jump around. If they click the print button it is printed. For the most part, I have eliminated the need for printed reports, since they have them filed and can look at reports anytime they wish. The system also lets you set up reports to run at certain times, like every Monday morning at 8:00AM, and copy as many users as you want. The report then shows up in everyone's IN BASKET at 8:00AM Monday.

So far the feedback has been great, and eliminated a lot of paper reports laying around, that they usually don't look at anyway.

Every system is different and it may not fit your application. But I Hope this gives you some help or ideas.

Have a great day.... Dan

$_POST doesn't exist in PHP 3. Use $HTTP_POST_VARS. Also check your settings of track_vars and register_globals in PHP.ini (or your phpinfo() page). Check the manual on what each of those settings mean and how they affect your script, too.

Don't know. The changes are documented in the ChangeLog available in CVS at http://cvs.php.net and on pages linked from the home page of PHP http://php.net/

I reckon you can read them as well as I can.

Past upgrades have remained largely backwards-compatible, and I expect PHP 4.3/5 to also do so. There will always be exceptions for various reasons.

In the past, upgrades to PHP have simply altered the existing on-line manual. I would expect that the next version would also do so, but only the PHP Documentation team would know for sure.

There will never, ever, be a completed documentation for PHP on-line, or anywhere else :-) Generally, the PHP docs "lag" behind the actual functions by a few weeks or so, depending on who wrote the functions, and how many people use/need those functions. Functions with few users and/or more complicated interfaces may lag woefully behind average. Feel free to join the documentation team and reduce this lag time. :-)

I trolled for answers to the "when will PHP 5 happen" in the PHP-Dev list recently. Use the archives. Search for "tea leaves" to find the thread. YMMV. Note that all the answers, if any were public, were "off the record"

I have some pages which include a number of files. In one of the include files I have a function which I wish to be executed everytime the include file is loaded.

Therefore I place the function name in the include file at the top.

However, this function uses a session variable to decide whether to call another function and it appears that this variable is not being carried across. For example, the start of the include file might look like this:-

<?php

checkMaster();

function checkMaster() { global $master_session; if ($master_session[db_host]) { connectToDB(); } }

function connectToDB() { ... ....

The master_session variable is not set and hence connectToDB is never called. If I place the checkMaster code in each page that includes this file then it all works fine. How do I get round this?

Thanks.

Hmm. Here's how you can make it load EVERYtime the file is included, plain and simply. In the include file, create the function.and the call it after you've made it. To get the other function to work, you might want to try placing the function ABOVE checkMaster(); (you should probably simply put that in the same file, but above it). functions.php <? function myfunction () {}

myfunction(); ?>

I have the feeling that the problem with the session variable is that you're calling it before anything has been done to define it in the main page, so it is null when you check it. Try debugging it with echo statements here and there that call out variables so that you know they're defined correctly. Also, turn on "error_reporting(E_ALL);" (you can simply call it at the top of the page--first thing). That will tell you when variables are used if they're null and other errors that aren't fatal, but might cause problems.

I think that you need to call the checkMaster() function AFTER you declare it, not before. Try moving "checkMaster();" beneath the function definition.

I would not expect this to work. PHP is going to finalize and return the class, and you're assignment to $this is meaningless.

If you want this to work, you'll have to do more like this:

<?php $cache = array(); function new_A(); global $cache; if (!isset($cache['A'])){ $cache['A'] = new A(); } return $cache['A']; } ?>

In other words, keep your cache "external" to the actual object implementation.

If you're going to do this from a web-page, you will need some kind of shell script with 'sudo' (man sudo) permissions to do what needs to be done.

*OR* add a new mime-type to your httpd.conf that runs PHP as a CGI as the 'postgres' user which *does* have permission to do this.

*OR* alter the permissions of pg_dump to be world-executable, and of the directory where the files are stored as well.

*OR* just pass in the username/password using -U to pg_dump (man pg_dump)

*OR* ...

There's a zillion ways to skin this cat, but which is least risky (or even possible) depends on who can access the box, who can access the web page, and whether or not you have root access on the box.

Don't use just language[] Use language[$devid]

Same answer. Use some reasonable variable name, with [$devid] after it.

>2) How can I manage them after the form was submitted?

while (list($dev_id, $lang) = each($language)){ }

I'll use that as the template:

I'll assume that you know how to get the expid and devid in there and I'll just put them in there as numbers. <? $devselect = "<SELECT NAME=\"devtime[]\" SIZE=\"1\"> <OPTION VALUE=\"<1y\">Less than 1 year <OPTION VALUE=\">5y\">More than 5 years etc </SELECT>";?>

<FORM><TABLE> <TR> <TH>expid</TH><TH>devid</TH><TH>devlangu</TH><TH>devtime</TH> </TR>  <TR> <TD>1</TD><TD>1</TD><TD><?=$LanguageName[$expid]?><INPUT TYPE="Check"<? if ($UserKnows[$expid]) { echo " CHECKED"; }?> VALUE="language[]"></TD><TD><?=$devselect?></TD> </TR>  <TR> <TD>2</TD><TD>1</TD><TD><?=$LanguageName[$expid]?><INPUT TYPE="Check"<? if ($UserKnows[$expid]) { echo " CHECKED"; }?> VALUE="language[]"></TD><TD><?=$devselect?></TD> </TR> etc...  <TD>-</TD><TD>1</TD><TD><INPUT TYPE="Text" NAME="DevSetLang[]" VALUE=""><TD><?=$devselect?></TD> etc.. </TABLE></FORM>

Now you can access them by (I think) doing something like this: if (!empty($_POST["language"][0])) // (I think that check boxes give "" if they're not checked) if (!empty($_POST["DevSetLang"][0])) // you might consider making a separate "devselect" variable for the text boxes, which will make it easier to check (the array index will work easier)

I hope that that helps.

There are probable even more browsers that can't handle the META tag...

Which versions of IE is somebody claiming can't handle a Location: header?

Cuz, like, even IE *CAN'T* be that broken, can it?

I believe it says "Array ( $whatevertheKEYis => $theVALUE, $nextKEY => $nextValue)" on screen for it. Basically, it makes it so you could copy and paste it and create a replica of THAT array. Mostly used for debugging.

How can I do this

I have a form that I want to submit to a second php script that in turn submits to a cgi script but I can not get it to work. If I submit from the form to the cgi script it works just fine. But there are something that I need to do with the data besides submitting to the cgi script. Could you look at the sample code below and see if I am doing something wrong. I hope this makes sense I am not quit sure how to ask what I want to know If I was submitting directly to the cgi script the form action would look like this <FORM ACTION="/cgi-bin/siteUserEmail/siteUserEmail.cgi" METHOD="POST">

In your example you are using the method of POST to pass the form data to the cgi script. However, when you pass the data to the cgi script from the php script you are using the GET method to pass the data.

Check and see if the cgi can accept with METHOD="GET"

Rite,

There's a PHP script that takes a monochrome BMP and converts it into some sort of hex code and I've noticed some patterns with this code. This image is 72 pixels wide by 14 high so there's 1008 pixels. In the code returned, theres 252 chars, which is 1008 divided by 4.

So I guessed the image is split into 4 pixels each. So if I pass an image with the first pixel black and everyhting else white, it returns 8 for those 4. If I pass an image with the first and second black, it returns c.

With the first three black, it returns e. With the first 4, f. And if I have the 5th pixel black it goes onto the next char code, eg returning f for the first 4 pixels, then 8 for the 5th pixel black, ie the first pixel in the next 4. In total it returns f8.

PS I tried reading in each pixel of the script, checking if it was black or white, 1 for black, 0 for white. Then converting these 0s and 1s from decimal to hex, then converting from binary to hex, but to no avail. Then I tried taking a set of 4 1s or 0s and converting them, but still no luck.

So my questions is, does anyone know how theyre encoding the image???? I could probably could decipher the coding with some experimentation but it really looks like hex and I might be wasting my time.
