[Support request] Adjusting results for display and autoplay in carousel

Hi Elvin,

Thank you once again for the replies. I would be thankful if i could have your help still, since there are a couple of issues.

Regarding questions #1 and #3: it works, but when i apply it but it makes the carousel only show one item/post “per slide”, instead of the 3 per slide that i had defined in the properties of the list. I added an if clause to apply it only to a specific carousel; the problem happens with or without the if clause:
add_filter( ‘wpsp_carousel_args’, function( $args ) {
if ( 1477 === $settings[‘list_id’] ) {
$args[‘autoplay’] = false;
return $args;
}
} );

Regarding #2, there seem to be 2 problems with the code you suggested:
– On the one hand, it does not change the length of the excerpt, at all. I replaced the “123” for the list_id and tried different values for the “return” value. No visible effect.
– On the other hand, it does not see to correctly restrict (match?) the first if condition just to the featured post. I replaced the “global $wp_query” expression with a simple echo “message”, to see if and where it would show up. Result: all the posts in the list showed that message between title and excerpt, not just the featured one. I’ve tried to dig into the plugin code to see how it is marked, but it goes past my know-how to find a solution 🙁

Any idea on how to proceed? I’ve tried to combine your suggestion with the function suggested in WordPress’s Code reference, but no luck either:

function mytheme_custom_excerpt_length( $length ) {
if ( 1496 === (int) $settings[‘list_id’] && $settings[‘featured_post’] ); {
global $wp_query;

if ( 0 === $wp_query->current_post ) {
return 10; // Whatever the length you need for the first post.
}
}

return $length;
}
add_filter( ‘excerpt_length’, ‘mytheme_custom_excerpt_length’, 999 );

Thank you in advance and best regards,
Paulo

Dear Tom,

Thank you for the follow-up and suggestion.
The first question is solved, but the excerpt length one unfortunately not.

I’ve tried the suggested code but it changes the excerpt length for all the posts in the list, not just the featured post (as desired). Upping the priority to 1000 did not make a difference. I had also replaced the ); ) { with ); { by at the end of line two as it threw a validation error.

For now, i simply added a manual excerpt to the featured post, but it would be preferable to have the automatic behaviour in place, if possible.

Would it help if i give you access to the dev site?

I really appreciate your continued support! Best,
Paulo

Thank you once again. I’m not quite sure i get the full implication of your answer but i get the gist of it 🙂

Since having the conditions inside the add_filter does not work, would it help to define the function custom_excerpt_length before calling the add_filter?

In the function, we could define the custom excerpt length if the post is in a given WPSP list and if it’s the latest published one (as in “if ( 0 === $wp_query->current_post )”); otherwise, the normal excerpt would be applied. I’ve tried fiddling with the code but this is above my know-how.

It could be a question for stack exchange but i’m not sure how much the solution is dependent on any given specificity of WPSP (ie interaction with the different WP classes, etc).

Thanks in advance,
Paulo
