Hi:
I believe that if you reference the form element like:

document.forms['mycell[]'].value

you will get what you want.

Which means you have to give your text elements unique names. IE mycel[0]
instead of mycel[] etc.

Hi- Is there any way to get all of the elements in a SELECT MULTIPLE box, not just the ones that are selected? Thanks! -Greg

attached mail follows:

use [] in your select box name. When it comes back in the $_POST array you will have an array of options. It breaks HTML standard therefore it is a Bad Thing (tm) but it does work.

Selecting both results in:

$_POST['mySelect'][1] == "Don't pick me" $_POST['mySelect'][2] == "Pick me"

No. You create the box, so you should know all of the possible values.

Sessions themselves use cookies, though, right? So, if you want your app to work for those who don't have cookies, you have to pass the session data in the url string, at least that's my understanding.

Hi,

I've just spent the night upgrading my RedHat 6.2 server to:

Apache 1.3.27 PHP 4.3.0 MySQL 3.23.54a Mod_SSL 2.8.12 OpenSSL 0.9.7 ZendOptimizer 2.1.0

Now I'm getting (inconsistently):

PHP Fatal error: Unsupported operand types in /web/domain/html/includes/item.inc on line 35

That line contains: $variable1 = $variable2 - 1;

Both variables may be unassigned prior to this line, or may have numeric values.

In a related piece of weirdness, I have this included at the bottom of every file:

<?php if(mysql_error()) { $MYSQL_ERROR = mysql_error(); $MYSQL_ERROR_NO = mysql_errno(); $date = (date("l F d, Y g:i A")); mail("briandomain.com", "Database Error", "

Errors: $MYSQL_ERROR_NO:$MYSQL_ERROR

Query: $query_log

Page: $PHP_SELF Date: $date

","From: Webmaster <webmasterdomain.com>"); ?>

Which normally returns something like:

------------- Errors: 1062:Duplicate entry 'emaildomain.com' for key 1

Query:

Page: /account/new.html Date: Friday January 17, 2003 12:42 PM

But now it returns: ---------------- Errors: Saturday January 18, 2003 3:18 AM:Saturday January 18, 2003 3:18 AM

Query: Array

Page: /community/newsletter.html/2001-03-01 Date: Array -------------

How can $date be an array, when it gets assigned right above where it gets called?

What am I missing in this new version of PHP that is making my scripts seemingly incompatible?

Thanks, Brian Allen

attached mail follows:

I prefer single quotes on stuff that doesn't need to be parsed. In most cases this is more efficient, though probably not noticed except on a large scale. I also think it makes it easier to include html strings (because double quotes don't need to be escaped) and I find it easier to work my code in Homesite.

echo '<p>'.$something.' '.$something_else.'</p>'; rather than echo "<p>$something $something_else</p>";

Since no one else has asked, I'll bite. Why not just use str_rot13()?

<brutal> The biggest problem I have with your code is that you didn't learn enough about the language to know that this was already in the code. As a newb, you need to set down with your favorite version of the manual (I keep the windows help version open at all times) and familiarize yourself with the language. You do not need to memorize each function' signature but it would help if you read the description of each function. You'll be surprised what you find in there. </brutal>

Well, here's your chance to criticize a newbie.

As an exercise in learning PHP I have written a rot-13 script. It is at http://hutnick.com/rot13/index.html?show_content=1 .

I'm soliciting comments on style, technique, etc. Be brutal, but don't get your feelings hurt if I don't take your comments as gospel. References will help me take comments to heart.

It will be easier on me if you send or CC comments to phphutnick.com.

Thanks a million!

If your script is in the form of a PHP class of objects, you may want to try uploading it to the PHP Classes site. You will not get explict reviews, bu your work is exposed to tens of thousands of PHP users eager to learn about new classes.

Until now I haven't had the need for a free PHP host because what I have done has been commercial.

However, In this case I am doing the website for my PC Gaming clan. We are one step below needing php to do alot of stuff.

Does anyone know of a free php webhost? (Banners, poop-ups etc are exceptable).

Why is that?

As with many "bugs" it's because I told it to! To my surprise, MySQL varchar fields have their trailing spaces removed on insertion. Tinyblob or Tinytext fields do not, so one needs to use those (or their larger brethren) when saving encrypted or binary data to MySQL. Thanks to those who tried to help!

I want to do this for multiple files. I tried to do this with a foreach -loop but I think I made some mistakes with the array "userfile". In this example userfile is just the "name" in the input tag. When uploading multiple files userfile is -ofcourse- an array like this: name='userfile[]'. Now I want to know how to handle with that array in somekind of a loop. For one file the script is this:

if (is_uploaded_file($_FILES['userfile']['tmp_name'])) { $namename=$_FILES['userfile']['name']; move_uploaded_file($_FILES['userfile']['tmp_name'],"/path/$namename"); if (rename("/path/$namename", "/path/$uartist-$usong.mp3")) { $query = "INSERT INTO table (column1,column2,column3) values ('$value1','$value2','$value3')"; mysql_query($query) or die ("Couldn't make query!"); print "File Upload and rename succesful!"; } else { print "File Upload failed!"; }

Hello

I checked the PHP manual and couldn't find anything on this...

When I call session_register() an implicit call to session_start() is executed. So if the session handling uses cookies to track the session and the call to session_register() is not before any output this will cause a header allready sent problem. Is this correct?

If so how can I call a register session from within a class and make sure that the session is allready active and if not just print a warning.

For background information: The class mentioned above is part of a classlib used by others and I can not guarantee that they call session_start since I have no controll over how my class lib gets included. So the issue here is if it is possible to create a backup for this problem or if I just have to rely on the user of the classlib to understand the mechanisms of session tracking. Any ideas on this? What do you consider best practice in this matter?

Thanks for all the advice I have received so far

attached mail follows:

Yes, just user $_SERVER['PHP_SELF'] as the action of your form. This will cause the page to call itself. Then you can branch your processing on the existence of a SUBMIT button (or whatever) and handle the query.

I do all my pages this way because it keeps all the code in a single page. It's easier for me to find it that way.
