How hard would it be to get a summary of the post listed on the main page under the topic? Like the first 300 words or so.

Has this been mentioned in any other threads?

I was dabbling around with this a little earlier and was curious. Can it be done with just a simple theme change? Or would it be best to just do it as an extension? I am thinking extension would probably benefit everyone more. I need it for a theme I am working on.

Any ideas? Where would be a good place to start?

Krak

Wow, I should have searched harder.

Not exactly using the same words though.. disregard this post.

Did you find an answer on this question?

Anyone?

This has never been done nor, so far as I know, answered with a specific technical tip.

Tex

That's a pity as I would really need this. Thanks anyway.

i am really interested in this too.

i'm pretty sure that the answer was found in version 0.9.2 of vanilla, so here's something for anyone who wants to work on it

this isnt a foolproof way but it'll work none the less
$string = 'find your own string...'; $string = explode(' ', $string); echo implode(' ', array_splice($string, 0, 300));

here's a slightly more 'friendly' preview function, dosn't really consider html markup, though...

function getpreview($text, $len)
{
	if(strlen($text) <= $len) return $text;
	
	//first check to see if we can seperate paragraphs
	for($i = $len; $text[$i] != "\n" && $text[$i] != "\r" && $i > 0; $i--) ;
	for(; $text[$i] == "\r" || $text[$i] == "\n" && $i > 0; $i--) ;
	if($i > 0) return substr($text, 0, $i + 1);
	
	//now try punctuation
	for($i = $len; !ctype_punct($text[$i]) && $i >= 0; $i--) ;
	if($i > 0) return substr($text, 0, $i + 1) . ' ...';
	
	//and lastly, any spaces
	for($i = $len; !ctype_space($text[$i]) && $i >= 0; $i--) ;
	if($i > 0) return substr($text, 0, $i) . ' ...';
	
	//if none of the above, just return a substring
	return substr($text, 0, $len) . ' ...';
}

vincent, sirnot, can you please let us know where to paste the code above? or am i jumping the gun?

Is this discussion asking about the same thing as this one?

Krak

Stash - That post is exactly what I was looking for yes.
