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 + $taglength + 3;
}
}
while ($pos !== false);
if (count($end_pos) == 0)
{
$quit = true;
}
if ($quit == false)
{
// merge them together and sort based on position in string
$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 = '';
$substr_pos = 0;
foreach ($pos_list AS $pos => $type)
{
$stacksize = count($stack);
if ($type == 'start')
{
// empty stack, so add from the last close tag or the beginning of the string
if ($stacksize == 0)
{
$newtext .= substr($text, $substr_pos, $pos - $substr_pos);
}
array_push($stack, $pos);
}
else
{
// pop off the latest opened tag
if ($stacksize)
{
array_pop($stack);
$substr_pos = $pos + $taglength + 3;
}
}
}
// add any trailing text
$newtext .= substr($text, $substr_pos);
// check to see if there's a stack remaining, remove those points
// as key points, and repeat. Allows emulation of a non-greedy-type
// recursion.
if ($stack)
{
foreach ($stack AS $pos)
{
unset($pos_list["$pos"]);
}
}
}
while ($stack);
$text = $newtext;
}
}
$i++;
}
return $newtext;
}
