Custom trim my post title item combine two if - php

Question

based on this example
add_filter( 'facetwp_builder_item_value', function( $value, $item ) {
if ( 'post_excerpt' == $item['source'] ) {
$value = substr( $value, 0, 120 );
}
return $value;
}, 10, 2 );
I would like to trim post_title to a maximum limit of 120 with the (...) at the end.
This objective was not achieved with my modification and I failed several times with several combinations
// my actual attemp to trim post_title item
add_filter( 'facetwp_builder_item_value', function( $value, $item ) {
if ( 'post_title' == $item['source'] ) {
$raw_value = $item['source'];
if ( 120 < strlen( $raw_value ) ) {
$value['source'] = substr( $raw_value, 0, 120 ) . "...";
}
}
return $value;
}, 10, 2 );
following the logic of the things based on this exemple mentioned here
// Add the following to your theme's functions.php
add_filter( 'facetwp_index_row', function( $params, $class ) {
if ( 'aufsichtsbehoerden' == $params['facet_name'] ) {
$raw_value = $params['facet_value'];
if ( 50 < strlen( $raw_value ) ) {
$params['facet_value'] = substr( $raw_value, 0, 50 ); // cut off some of the value
}
}
return $params;
}, 10, 2 );
Experts in PHP and use filters are requested to join me to tell me what I missed as a modification ..

Answer 1

Nest your if statements, and add some way of tracking the bug.
add_filter( 'facetwp_builder_item_value', function( $value, $item ) {
if ( 'post_title' == $item['source']) {
$maxLength = 120;
echo "POST TITLE == ITEM SOURCE";
if (strlen($value) > $maxLength) {
echo "POST TITLE EXCEEDED MAX LENGTH";
$value = substr( $value, 0, $maxLength) . '…';
}
}
return $value;
}, 10, 2 );
I have added two echo functions to allow you to understand where and when the conditions are met.

Your first if is doing nothing in the first code. Notice that there are nothing between its brackets { }.
Your second code is combining both conditions correctly. If it doesn't work, 'post_title' is probably not equal to $item['source'].
