preg_replace problem

dtannen

Hi,

I could use a little help please. I am attempting to append the param k=12345 to each x.swf located between <object> tags. If there is existing params, I need to add one with & and if not then add it with ?. So far I have...

<?php 
$patterns[0] = "/(<object>)(.*)(\S\.swf(?=\?)\S+)(.*)(<\/object>)/is"; 
$patterns[1] = "/(<object>)(.*)(\S\.swf(?!\?))(.*)(\/object>)/is"; 

$replacements[0] = "\$1\$2\$3&k=12345\$5\$6"; 
$replacements[1] = "\$1\$2\$3?k=12345\$4\$5"; 

print preg_replace($patterns, $replacements, $stringin); 
?>

Assume that $stringin is the entire html file. The code above only replaces the last matching value-- so...

Html:

returns:

Html:

I need both x.swf?testvar=1 to change to x.swf?testvar=1&k=12345.

Help.

Thanks.

Seems a little too complex, simplify:

pattern
'/(x.swf\?)(\w+=\w+)/is'

replace
'$1$2&k=12345';

function callback($s) {
                /* This replace will replace properly replace info between an object tag */
                $patterns[0] = "/(\.swf(?=\?))(\S+)/is";
                $patterns[1] = "/(\.swf(?!\?))/is";
                $replacements[0] = "\$1\$2&k=12345";
                $replacements[1] = "\$1?k=12345";
                return preg_replace ($patterns, $replacements, $s[0]);
        }

    print preg_replace_callback ("/<object>(.*?<\/object>/si", "callback", $stringin);
