Get […] after custom excerpt

Take a look at wp_trim_excerpt()

Try the function below, which hooks to get_the_excerpt filter.

/* Hook the rebah_custom_excerpt_more() function to 'get_the_excerpt' filter hook */
add_filter( 'get_the_excerpt', 'rebah_custom_excerpt_more' );

/**
 * Add [...] after custom excerpts.
 *
 * @param string $output [...]
 * @return string $output [...]
 */
function rebah_custom_excerpt_more( $output ) {
	if ( has_excerpt() && ! is_attachment() ) {
		$output .= ' […]';
	}
	return $output;
}

I looked at the wp_trim_excerpt already, but I still dont know what to do. I’m a total newbie to code and WP.

Jamàl, I added this code to functions.php. Is that the right file?
Do I also have to change the code I used mentioned in my first post or should it just work. So far it doesn’t.

Rebah,

I added this code to functions.php. Is that the right file?

Yes. The code goes into your active theme’s functions.php file.

Do I also have to change the code I used mentioned in my first post[…]

Yes. Remove that code, and use the standard <?php the_excerpt(); ?> template tag.

The function I posted in my previous post checks if the post have a custom excerpt, and the post in question is not an attachment; it then appends [...] at the end of the custom excerpt text if the condition is true.

I think that I maybe wasn’t clear enough about the custom excerpt, because now with your method I can’t define the characters of the excerpt anywhere, right?

My intention is this:
On my homepage I have the excerpt of my posts, and beside that I have a slider as header with the same posts. I want the excerpt in the slider to be shorter then the excerpt on the page below. That worked with the code in my first post, but without the […]

Well, you can append the ellipsis at the end of your original code.

Example:

<?php echo substr( get_the_excerpt(), 0, strrpos( substr( get_the_excerpt(), 0, 75), ' ' ) . '[...]' ); ?>

I used the code in your example but the ellipsis aren’t showing…

So after some experimenting i got it today. I used:

get_the_excerpt(), 0, strrpos( substr( get_the_excerpt(), 0, 75), ' ' )); ?> [...]

Thanks for the help
