[RESOLVED] have php search html code and ad target="_blank"

fearfx

Ok I have a html code that looks like this..

How can I determine if this image link is set to open inside a new browser and if not

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 search

I 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?

bradgrafelman

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...

bradgrafelman

You'd just remove ".<img.>" from the pattern.

Thank you very much. You were very helpful. And again thanks to the phpbuilder community!
