Display Excerpt - El Forum - 01-04-2011

I was wondering if there was a way to display an excerpt of a blog topic and/or video description? I saw in the user guide that you could use the Trackback Class. I noticed that it said that the lowest it goes is 500 characters. Is there was something to where less was shown?

I used a custom function on mine to be honest:
Code:
function excerptString($string, $desLength, $endChars = '...', $before = '1', $offChar = ' ')
{
if (strlen($string) < $desLength)
{
return $string;
}
switch($before)
{
case 0:
$partialString = substr($string, $desLength, strlen($string));
$endPosition = strpos($partialString, $offChar);
return substr($string, 0, $desLength+$endPosition).$endChars;
break;
case 1:
$string = substr($string, 0, $desLength);
$endPosition = strrpos($string, $offChar);
return $string = substr($string, 0, $endPosition).$endChars;
break;
}
}Further explanation of how to use it is here:
