Hiding a Div from an Excerpt

Anyone have any ideas?

I have half an idea here. Maybe someone can chime in with the other half.

An easy way to hide content with CSS is to add “display:none;”. So, if you poke around the CSS structure of WordPress, I’d bet there’s a class or id used within the excerpt you could piggyback with your adjustment.

The problem is that the excerpt is removing all html tags.
So the solution is to write a function that looks for these div (better to identify them with a class), and with a hook, removes them from the excerpt before loading.

Hi everyone

After a lot of fiddling around today I’ve worked out a solution that’s worked for me. It might need a bit of customising if anyone else wants to use it depending on how they format the posts.

Firstly I’ve opened the wp-includes/formatting.php file and found the following snippet of code.

* @param string $text The exerpt. If set to empty an excerpt is generated.
 * @return string The excerpt.
 */
function wp_trim_excerpt($text) {
	$raw_excerpt = $text;
	if ( '' == $text ) {
		$text = get_the_content('');

		$text = strip_shortcodes( $text );

		$text = apply_filters('the_content', $text);
		$text = str_replace(']]>', ']]>', $text);
		$text = strip_tags($text);
		$excerpt_length = apply_filters('excerpt_length', 55);
		$words = explode(' ', $text, $excerpt_length + 1);
		if (count($words) > $excerpt_length) {
			array_pop($words);
			array_push($words, '[...]');
			$text = implode(' ', $words);
		}
	}
	return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}

Apparently you can copy this piece of code and paste it into your theme’s ‘functions.php’ file but I couldn’t get this to work (I think because I have my excerpts on a seperate page that is not directly linked to my wordpress blog and therefore probably skips the themes.

I ended up changing the code in the original formatting.php file.

I simply added
$text = strip_tags($text, '<div>, <ul>, <li>');

Then on my style sheet I added display:none; to the divs (and the ul and li) items that I wanted hidden. I found this has made my excerpts look a lit tidier.

I’m sure there is a more elegant and flexible solution but this has served it’s purpose for myself.

You’ll be very happy to repeat the modification at each upgrade…

As I said.

I don’t upgrade as a matter of course anyway. If the page is working and serving it’s purpose why upgrade unnecessarily. Of course if new features come about that I feel are worth upgrading for then I will, I will also add the 21 characters of code back into this page to fix things.

Just document your mods carefully for yourself so you can re-apply after any WP upgrade that you do.

Or, convert the mods into a simple plugin, and you probably won’t need to re-add the custom code for each WP upgrade.
