How to remove HTML tags from thread preview (good for HTML-enabled forums especially)

Don't you just hate it when thread previews show HTMl tags even though browsers don't interprete those tags in popup menus? Well then this hack is just right for you!

This hack will remove all HTML tags such as <b>, <i>, <strong> and even closing tags like </b>, </i>, and </strong> so that they don't show up in the thread preview. It's genius they say!

Anyways here we go:

open up forumdisplay.php and find

PHP Code:

                eval('$threadbit .= "' . fetch_template('threadbit') . '";'); 

Above, add

PHP Code:

                $thread[preview] = eregi_replace('(")','',strip_tags(unhtmlspecialchars($thread[preview]))); // solution #2 

If the above code doesn't show some thread previews properly, try the one below:

PHP Code:

                $thread[preview] = eregi_replace('(&[a-z]+;|<[a-zA-Z]+>[a-zA-Z]+</[a-zA-Z]+>)','',strip_tags($thread[preview])); 

All done

Nice, but why not just

PHP Code:

$thread[preview] = strip_tags($thread[preview]); 

?

Fixed (You needed unhtmlspecialchars()) first.

[Andreas]

Hmm ... now this code might produce invalid XHTML (thinking of quotes and ampersand).

*testing* I'll post back with a full solution when I have one, should take a few minutes only heh

[Andreas]

PHP Code:

 $thread[preview] = htmlspecialchars(strip_tags(unhtmlspecialchars($thread[preview]))); 

might do the trick
