[solved] Automatic removal of [img] and [youtube] tags when quoting posts
 
Often, people quote posts that contain an embedded video or a large image, and when it's done excessively it takes up a lot of unnecessary vertical space (more scrolling) and can cause the threads to take longer to load.

Can images and videos using [img], [youtube], [youtubehd], [video] and other such tags be changed to just the URL of the image or video when using "Reply With Quote"? How can I go about this?

Thanks.

Is that what you're looking for?

While this isn't exactly what you asked for, what I did was edit the strip_quotes function in the file /includes/functions.php, with an array of tags literally defined to simply be removed, along with their contents:

PHP Code:
// #############################################################################
/**
* Strips away a defined set of tags and their contents from the specified string
*
* @param    string    Text to be stripped of tags
*
* @return    string
*/
function strip_quotes($text)
{
    $tags = array('quote','desmos','graph','img','video','vimeo','youtube');
    $i = 0;

    while (isset($tags[$i]))
    {
        $lowertext = strtolower($text);
        $stack = array();
        $start_pos = array();
        $end_pos = array();
        $quit = false;
        $tag = $tags[$i];
        $taglength = strlen($tag);
        $newtext = $text;

        // find all opening tags

        $curpos = 0;
        do
        {
            $pos = strpos($lowertext, '[' . $tag, $curpos);
            if ($pos !== false AND ($lowertext[$pos + $taglength + 1] == '=' OR $lowertext[$pos + $taglength + 1] == ']'))
            {
                $start_pos["$pos"] = 'start';
            }

            $curpos = $pos + $taglength + 1;
        }
        while ($pos !== false);

        if (count($start_pos) == 0)
        {
            $quit = true;
        }

        if ($quit == false)
        {

            // find all closing $tag tags
            $curpos = 0;
            do
            {
                $pos = strpos($lowertext, '[/' . $tag . ']', $curpos);
                if ($pos !== false)
                {
                    $end_pos["$pos"] = 'end';
                    $curpos = $pos + $taglength + 3;

                $pos_list = $start_pos + $end_pos;
                ksort($pos_list);

                do
                {
                    // build a stack that represents when a tag is opened
                    // and add non-tag text to the new string
                    $newtext = '';
                    $substr_pos = 0;

Thanks guys. Dave's link seemed to work.

MarkFL: does your suggestion do anything different?
