Ok I have a html code that looks like this..
<a href="http://click.linksynergy.com/fs-bin/click?id=WdDkqYkmPps&offerid=134830.10000191&type=4&subid=0"><IMG alt="Bidz, Inc." border="0" src="http://s3.amazonaws.com/bidzmarketing/091907/300x250_$1_redvelvet.jpg"></a>
How can I determine if this image link is set to open inside a new browser and if not
ad
target="_blank" into the html code where it belongs?
Hm... something like this might work:
function forceNewWindow($str) {
if(!preg_match('/target=["\']_blank["\']/i', $str))
$str .= ' target="_blank"';
return $str;
}
$pattern = '@(\<a\s+)(href.*)(>.*<img.*>.*</a>)@sUie';
$replace = '"$1" . forceNewWindow("$2") . "$3"';
$html = preg_replace($pattern, $replace, $html);
//$html is the variable taht contains the HTML data to searchI just want to point out that the "target" attribute is on its way to being deprecated and is only valid in a "loose" DTD; so if you really feel the need to do this (which many users find annoying), be sure that the page is a using a "loose" doctype declaration and not a "strict" one.
Ah yes, I was going to mention that... I'd read an article somewhere about using rel="external" or something... guess I need to brush up on some W3C standards.

Eh...why bother? Microsoft doesn't seem to think it's important to. 
<?php
$str = '<a href="http://click.linksynergy.com/fs-bin/click?id=WdDkqYkmPps&offerid=134830.10000191&type=4&subid=0"><IMG alt="Bidz, Inc." border="0" src="http://s3.amazonaws.com/bidzmarketing/091907/300x250_$1_redvelvet.jpg"></a>';
function forceNewWindow($str) {
if(!preg_match('/target=["\']_blank["\']/i', $str))
$str .= ' target="_blank"';
return $str;
}
$pattern = '@(\<a\s+)(href.*)(>.*<img.*>.*</a>)@sUie';
$replace = '"$1" . forceNewWindow("$2") . "$3"';
$html = preg_replace($pattern, $replace, $html);
echo $html;
?>
would this be the way to use this function?
No. As I said, $html is the variable you supply that as the HTML code to be searched.
great works wonderful, 1 more question what would I change just to search through a normal link... without an image...
You'd just remove ".<img.>" from the pattern.
Thank you very much. You were very helpful. And again thanks to the phpbuilder community!
