My sliders cut words after a certain amount of symbols.

Get Better Excerpts ( https://thisismyurl.com/plugins/get-better-excerpts/ ) will do it for you, or you can grab the code from there and use it in your code.

Something like…

$words = 10;

$short_title = implode (' ', array_slice (explode (' ', get_the_title ()), 0, $words));

Of course that can be enhanced a fair bit to do different things, but that’s the base for it all.

I paste it like this

// display only first 58 characters in the slide title.
$words = 4;

$short_title = implode (' ', array_slice (explode (' ', get_the_title ()), 0, $words));

											$short_title = substr(the_title('','',FALSE),0,58);
											echo $short_title;
											if (strlen($short_title) >57){
												echo '...';

But nothing changes..
@christopherross, I downloaded… installed… have no idea what to do next.
Sorry. I’m new with HTML and coding…

Here is the whole slider code…

?>
<?php
	$slider_cat_id = max_magazine_get_option( 'slider_category');
	//if no category is selected for slider, show latest posts
	if ( $slider_cat_id == 0 ) {
		$post_query = 'posts_per_page=5';
	} else {
		$post_query = 'cat='.$slider_cat_id.'&posts_per_page=5';
	}
?>

You’ve done exactly what I thought htat you migh thave. ?? But don’t worry, we’ve all made the same mistake many (many…) times over.

$words = 4;
$short_title = implode (' ', array_slice (explode (' ', get_the_title ()), 0, $words));
$short_title = substr(the_title('','',FALSE),0,58);

What you’ve done there is set $short_title with what I’ve suggested,and on the very next line you’re setting it again which over-writes what you had before so you get the same value. You can either take the second line out, or you can comment it out by adding // right at the start of the line like this:

$words = 4;
$short_title = implode (' ', array_slice (explode (' ', get_the_title ()), 0, $words));
// $short_title = substr(the_title('','',FALSE),0,58);

@catacaustic Works!
But.. Only one thing.. We have lost “…”
Usually on topic (and sub topic) we have more than 5 words. How I can say to HTML “cut after 4th word and than insert …”?
Thank you.

echo $short_title."..."

That’s doing it for everything. There’s more that you can do to check if it’s more then 4 words, but that involves moving things around a fair bit. It’s not hard, but this might be a time to get a bit of practice with PHP to get it to do what you want it to. ??

@catacaustic Thank you so much.
If I could say “Thanks” to you through Facebook, let me put you a like:)
