preg_match_all strange behavior

[hrisafis]

Hello to everybody

 

I have a problem with the following pattern

 

When I use this  preg_match_all('/<\a href="show_per.phtml\?id=(.*)" class="more_new">(.*)<\/a>/', $result, $shop_url, PREG_SET_ORDER );

everything seems to be fine, but when I send the pattern '/<\a href="show_per.phtml\?id=(.*)" class="more_new">(.*)<\/a>/'  through an html form and use this  preg_match_all($_POST['pattern'], $result, $shop_url, PREG_SET_ORDER );  nothing seems to work fine.

 

Why is that?

Any help will be really appriciated.

 

Thanks a lot.

The part of the code that interests me is something like this.

Sorry I posted the whole code the part you need is actually this:

nbsp;   <a href="show_per.phtml?id=PER.523596" class="more_new">περισσότερα >>  </td>

 

[rajivgonsalves]

were is the closing tag for the href anyways try this

 

preg_match_all("/<a href=\"show_per.phtml\?id=([^\"]+)\"[^>]+>([^<]+)/",$strText,$arrMatches);

print_r($arrMatches);

 

 

$strText is the actual string from curl

Nop not working again, I have to remind you that the pattern was working fine, it was when I sended the pattern as a variable through a form that I was not getting results.

 

[rajivgonsalves]

did you try to each the pattern ?

[hrisafis]

did you try to each the pattern ?

 

Please explain. What do you mean each the pattern?

[rajivgonsalves]

sorry I mean echo it you said you tried to send it through a form maybe extra slashes were added

Yes it could be any number of things, that your magic quotes settings add slashes automatically to post strings is probably a good guess though. A good general rule of thumb in any debugging is to validate/check your inputs/ouputs that you're getting at runtime. This means echoing out stuff.

The pattern looks fine:

Here's a function to auto escape slashes if neccesary:

<?php
function stripslash($str) {
if (get_magic_quotes_gpc()) {
	$str = stripslashes($str);
}
return $str;
}
?>

Seems to be working now, thanks everyone for your help!
