Don't worry about quotes - the problem is that you have HTML markup inside
your <textarea>. You just need to convert < and > to < and >,
respectively, in your link text. The functions htmlspecialchars() or
strip_tags() can do this for you.

i.e.:

<?
echo "<textarea>" . htmlspecialchars($link) . "</textarea>";
?>

When the form is submitted (and when it's viewed), those entities will be
converted back to their real characters automatically by the browser.

Simon-

Thanks for the tip...I trued using the htmlspecialchars() which allowed the
remainder of the form to display properly, but left no value in the
textarea. Then I noticed a difference in the method I was using compared to
yours - I'm still learning the ways of PHP so it will take me a while to
determine the significance of the syntax differences:

Mine: <td width = "60%"><?php echo $linkurl . '<br><textarea
value="htmlspecialchars($linkurl)"></textarea></td>\n' ?>

Yours: <?php echo "<textarea>" . htmlspecialchars($link) . "</textarea>" ?>

I wanted a graphical representation of the present link displayed above the
textarea and then attempted to use php's substitution to build the text area
within the same string. I updated my code to be more like yours and arrived
at:

<?php echo $linkurl . '<br><form>'?><?php echo "<textarea>" .
htmlspecialchars($linkurl) . "</textarea>\n"?>

which seems to make the parser behave as I intended.

Anyway...thanks!

Is it necessary to include the 'http:' in the DB field?

It would make your life a lot easier to drop it.

You would then store the url values as
www.mydomain.com

Then, modify your code to add the 'HTTP' whenever it encounter a URL, or
wherever you will create a link.

This would eliminate the need to deal with special characters...

Ah, the HTML <TEXTAREA> element does not support a VALUE attribute so your
way will not work. :)

Unlike <INPUT> tags, the contents (value) of a textarea should be inserted
between the <textarea>...</textarea> tags, rather than as an attribute.

Hence what you need is:

<td width="60%"><?php echo $linkurl . "<br><textarea>" .
htmlspecialchars($linkurl) . "</textarea></td>\n"; ?>

In the outputted HTML this will give you:

Which should render as a link, followed by a textarea with the HTML code for
that link. If you want the first link to render as code as well then you
need to run it through htmlspecialchars() too.

No it wouldn't, as the http:// is not the problem, the problem is the HTML
markup. What Paul could do is have two DB fields, for the URL and the link
text, and then form the <A> tag at runtime instead of in the data. But this
maybe is not what he wants.

<?php
$linkurl = "http://www.blah.com";
$linktext = "Blah";

echo "<a href=\"$linkurl\">$linktext</a>";
?>

Why store the html in the db? Why not have multiple db fields, say url and desc
then when you grab them from the db to be outputed put them into the html
print '<A HREF="'.$url.'">'.$desc.'</A>';

Then you wouldn't have to input all the html when it gets stored in the db, not
have to worry about quotes, or htmlspecialchars();. Also out of curiosity are
you stripping all tags but <A> from the input? Wouldn't want to get any nasty
users inputting <META> refresh tags or anything...

This must be why you guys get paid the big $$ <g>. I _never_ thought of looking at the HTML for errors, doh! Given the nature of the user who will be inputting the data (familiar with HTML) I will probable keep this 'quick-n-dirty' for now - I do like the multiple fields concept for future mods as it will allow for less-HTML literate users to easily build their links.

Thanks a bunch!

Hey...Bruno from Brazil :)

Try this

while ( list ( $key,$value ) = each($HTTP_POST_VARS) ) {

echo "$key: $value<br>"; }

This will list every variable that was past to the browser.

Enjoy!

Actually, you may not have to do all that.

you can use implode().

By default, implode will join an array, with the supplied character.

So, if you have $list = (one two three four);

you can do $all = implode("," , $list);

to get $all = "one,two,three,four";

This works pretty well...

enjoy!

a quite neat (though maybe no more efficient) way would be ...

$keys = array_keys($HTTP_POST_VARS); $key_list = array(); foreach($keys as $fred) { $key_list() = $fred."='".$HTTP_POST_VARS[$fred]."'"; } $updateString=$updateString.implode(",", $key_list)."'";

... I haven't tested the detail of this but the theory is sound, I'm fairly sure.

Your syntax is a bit convoluted there :-P

You could just do:

<?php foreach ($HTTP_POST_VARS as $var => $value) { $vars[] = "$key=$value"; } echo implode(",", $vars); ?>

I've created a simple form that uploads file to my server. I noticed that I'm having problems when I use Internet Explorer 4.5 and 5.0 on the Mac (I haven't checked it yet on the pc). It may have something to do with the path to the file. When I use Netscape, the entire path is displayed in the form field prior to upload. IE only displays the file name, no path. Is there a way that I could force the path along, echo maybe?

It sounds like your Apache configuration does not allow the php_value directive to appear in an .htaccess file. Check your error_log for a description of the problem.

In httpd.conf (or access.conf) find an applicable <Directory> block and check the setting of AllowOverride.

I'm not actually sure what the override setting you need is, but you could try Options or just All.

http://httpd.apache.org/docs/mod/core.html#allowoverride

Example:

<Directory /www/htdocs> AllowOverride All ... </Directory>

Of course, if you're able to edit httpd.conf then you could just put the php_value directive directly in there. :)

I'm not sure what is the original function design of session_destory(). Committing that, my code does not delete currently registered session data from memory. This result in writing currently registered session write to session database again unless programmer explicitly unregister them. If you want to delete session data in memory, you can do that in pg_session_destory() or anywhere in you can use

session_unset() to unset all session variables.

User session handlers are called in this order. session is started explicitly or implicitly then pg_session_open() called and data is read using pg_session_read() at that time programmer can see session variables. (If programer calls my pg_session_destory() it only deletes data in db and data is still in memory) connection is closed. pg_session_write() is called (since session data is in memory, write back to session database) then pg_session_close() is called.

I thought deleting only session data in database would give more freedom to programmers while working session variables. It might be better to put session_unset() in pg_session_destory(), if it suppose to.

Hello,

I've been reading a LOT on how to solve my problem today, but haven't been able to come up with anything yet.

Here's my problem: I have an html file that contains many table rows like this:

<tr><td>Item1</td><td>Item1 Again</td></tr> <tr><td>Item2</td><td>Item2 Again</td></tr> <tr><td>Item3</tr><td>Item3 Again</td></tr> <tr><td>Item4</tr><td>Item4 Again</td></tr>

And so on. I want to search this html for a table row that has 'Item3' in the first cell. And the second cell should contain 'Item3 Again'. I know that I can do this with something like this:

$file = fopen("http://localhost/html.html", "r"); $data = fread($file, 10000); $results = eregi("<tr><td>Item3</tr><td>Item3 Again</td></tr>", $data);

However, this won't exactly work for me, because that contents of the second cell will change daily, so tomorrow, the third table row could look like this:

<tr><td>Item3</td><td>Item3 Has Changed</td></tr>

I was thinking I could use sscanf() to do this, but couldn't get anything to work. I've tried everything I can think of.

Sorry if the explanation of my problem was hard to understand, I don't exactly understand it myself. Thanks everybody!!!

Regards, Tyler Longren

Maybe something along the lines of:

$results = eregi("<tr><td>Item3</tr><td>[a-Z 0-9]</td></tr>", $data);

You just need to use a regular expression with eregi:

<?php $data = "<tr><td>Item3</td><td>Item3 Has Changed</td></tr>";

eregi("<tr><td>([^>]+)</tr><td>([^>]+)</td></tr>", $data, $regs);

echo $regs[1]; // "Item3" echo $regs[2]; // "Item3 Has Changed" ?>

A good guide to regular expressions (which are absolutely indispensible if you want to do much work with strings) is here:

Yup, it will...

A good idea is to call exec() of a cgi script which sends email without time outs. CGI has it cute feature - never times out. I've seen it in some software.

The array is formed before the page is called. This is then passed to the page which prints it out.

could anybody please help me get my head around the following.

I get some url information from the database (title, url) I am trying to then put this into an array so I can pass it to the page to display a menu. so a) how do I get the data into the array. would this be the way to do it??

$menu = array(); while($db->next_record()) { $menu[]["name"] = $db->f("name"); $menu[]["url"] = $db->f("topic_id"); } which leads me onto b) how do I get the data back out. I can't test to see if the above works as I can't get at the data

use isset($action1) and isset($action2) to test each.

the nice way to do it would be for them to have the same name but different values as you would do with alternative submit buttons, but I haven't ever needed to find out how to do that and doesn't seem to be quite that simple.

That means, that those functions, already mentioned in the manual will work from then on I guess. I also wondered why those functions are mentioned, although they do not work yet.

The fix you mentioned, was not really correct, because the comment-parser at php.net replaces the <?php with <?php to avoid trouble with html-tags I guess. The fix describes there was just how to do an example pdf with for example php4.0.4pl1 and pdflib 3.0.3, because there is no pdf_new() in this versions. it worked fine for me and I hate the thought of changing my just finished pdf-project to the new functions.

if you removed the quotes around "false" it should work (as currently "false" is being treated as a string) but another way to do this is like :

// if not set then ... if ( !isset($AgeChild) ) {

$AgeChild = 'NA';

}

isset(): generally spoken, returns true if a variable is _defined_, regardless of it's actual value: isset($myvar) => returns false empty($myvar) => returns true $myvar = "something"; isset($myvar) => returns true empty($myvar) => returns false $myvar = ""; isset($myvar) => returns true empty($myvar) => returns true unset($myvar); isset($myvar) => returns false empty($myvar) => returns true

My advice: avoid comparing to false or true (and since these are constants, don't put them in quotes ;->). // bad way if (isset($myvar) == false) // better way if (!isset($myvar))

If the result is always something, for instance in the worth case it is 'N/A' then do:

if($AgeChild != 'N/A') you can continue

isset check if the variable has at least a byte in it.

so this will return true:

$var = ' '; if(isset($var)) echo 'got something in it';

Just check for what you know is inside (or not inside) the variable.

Yes. It allows cache proxies to cache the page. That means e.g. if Joe X (using ISP Y) fetches that page, *all* users of ISP Y will get the same page afterwards (including all his private data). Well, in practice proxies won't cache results of POST queries, but it's still a big security hole (never trust programs you don't admin yourself)

if (preg_match ('/\.(gif|jpg)$/i', $filename, $matches)) { echo "Congratulations, it's a " . $matches [1] . "!<br>"; } else { echo "Wrong file type!<br>"; }

Explanation:

/.../ are the "regular expression quotes", i.e. the real expression is between these slashes

The "i" after them means "do a case insensitive match" (a "pattern modifier")

\.(gif|jpg) means "match if the string contains a dot followed by either "gif" or "jpg""

The dot has to be escaped (prepended with a backslash) because a dot in a regexp has a special meaning: "match any char". The escaping makes it behave as a literal dot

The "$" means "here has to be the end of the string" (an "anchor")

=> the entire pattern means "match if the string ends with a dot followed by either 'gif' or 'jpg', and ignore case for this"

Hi,

I wondered if anyone knew what would be the better method to use to see if a file has been sent/uploaded?

method 1: if ($HTTP_POST_FILES['file']['name'] != "none" && $HTTP_POST_FILES['file'] != "") {

method 2: if ($fp = fopen($HTTP_POST_FILES['file']['tmp_name'],"r")) {

method 2 seems to work better, and seeing as I have to open the file on the next line testing to see if its there seemed the better way to do it?

How can I find out how long my scripts take to execute?

I'm currently using.. $stimer = timer(); // code ...... $etimer = timer(); echo "\n\nPage processed in: ". ($etimer-$stimer);

Function timer() { $milli = explode(" ", microtime()); return $milli[0]; }

Which works but is their a better way to do it?

Thanks, Matt

Nope unfortunately that does not work :(

Firstly using MAX() will not work as that finds the largest value in the group; SUM() would be more appropriate as it finds the total for that column in the group. But you can't group the data here (you want to select all page rows from the table) so these grouping functions are not usable.

He will need to do two queries:

<?php $result = mysql_query("SELECT SUM(hitcount) FROM pages"); list($totalhits) = mysql_fetch_row($result);

$result = mysql_query("SELECT (hitcount / $totalhits) * 100 AS percentage FROM pages"); ?>

I think...

$confidential = 0; # Numeric 0

That explains the 0.

$confidential == "yes"

This is a little tricky. The numeric value of 'yes' is 0, so it evaluates to the same thing as 0 == 0, which is true. True has a numeric value of 1, although all values besides 0 are considered true.

You might want to look at the === operator which checks that both the value and the type of the operands is identical.

Before redirecting it will also store a cookie in the browser named camefrom.

SO then On the login.php page a user enters username and pasword and Submits.. if user is found then It has to get the Cookie value like this:
