i get the following error, when i try to run a thumbnail script:

Fatal error: Cannot re-assign $this in /home/xxxxxxxx/domains/xxxxxxx.xxx/public_html/awse/awse_admin/inc.bulk.thumb.php on line 91

Line 90 and further reads:

$mext = "\.mpg|\.mpeg|\.avi|\.wmv";

    if (eregi("$mext",$this)) {
        $myimg = trim(preg_replace("/.*<img.+?src\\s*=\\s*[\"']?(.*?)[\"']?(\\s+|>)/is","\\1\\2",$this));
        if (!eregi("^http",$myimg)) {
            $myimg = $base.$myimg;
        }
            $img[$ti] = $myimg;
            $ti++;
    }
}



    }

    if ($ti<=4) {
        $split = 2;
    }
    else {
        $split = 4;
    }

    $mid = round($ti/$split);
    $img[$mid] = urlencode(trim($img[$mid]));
        if (!eregi("http",$img[$mid])) {

        }
        else {

can someone help me out ?

Try replacing it with:

foreach ($r3[0] as $this_var) {
    if (eregi("$mext",$this_var)) {
        $myimg = trim(preg_replace("/.*<img.+?src\\s*=\\s*[\"']?(.*?)[\"']?(\\s+|>)/is","\\1\\2",$this_var));
        if (!eregi("^http",$myimg)) {
            $myimg = $base.$myimg;
        }
            $img[$ti] = $myimg;
            $ti++;
    }
}

PHP:

 

$this is a special variable used for OOP. You can't use $this for your own purposes. Just use a different variable name, as steelaz says.

 

so if i understand correct, then i need to change it every where in the script and the included files to $this_var.

thanks guys for the quick answer.

 

It depends, if $this is used inside of class, then you should leave it as it is. Try running your script and see if it returns any more similar errors.

 

I got it working, perfect help guys. Guess it was clear i am not a Coder / scripter.

Anyway thousand times thank you.
