problem with custom_field_excerpt

You advised me to this code:
If you are looking to create a post excerpt, I would recommend you make use of the following function in your functions.php file:
function custom_field_excerpt() {
global $post;
$value = get_field(‘field_name’);
if ( ” != $text ) {
$text = strip_shortcodes( $text );
$text = apply_filters(‘the_content’, $text);
$text = str_replace(‘]]>’, ‘]]>’, $text);
$excerpt_length = 20; // 20 words
$excerpt_more = apply_filters(‘excerpt_more’, ‘ ‘ . ‘[…]’);
$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
}
return apply_filters(‘the_excerpt’, $text);
}

You can then replace this line $value = get_field(‘field_name’) with your custom field call and then on your template use the following code echo custom_field_excerpt();

BUT IT DOES NOT WORK:

Hi @inforesist

I’m not sure which thread you are referring to, but could you please try this code?

function custom_field_excerpt() {
    global $post;
    $text = get_field('wysiwyg_test', $post->ID);
    if ( '' != $text ) {
        $text = strip_shortcodes( $text );
        $text = apply_filters('the_content', $text);
        $text = str_replace(']]>', ']]>', $text);
        $excerpt_length = 20; // 20 words
        $excerpt_more = apply_filters('excerpt_more', ' ' . '[...]');
        $text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
    }
    return apply_filters('the_excerpt', $text);
}

Hope this helps.

Hi @inforesist

Could you please share the JSON export file of your field group and your PHP file where the code is located?

Thanks!

Hi @inforesist

I’m afraid the line at fault is not the code I gave you before. I’m sorry I can’t help you with it.

Thanks.
