My posts are built with flexible content and I need to show excerpts on archive pages. I’ve shown custom excerpts from fields before, but is it possible to get excerpts from sub_fields? The code I’ve used to get from a field:
function custom_field_excerpt() {
global $post;
$text = get_field(‘text’);
if ( ” != $text ) {
$text = strip_shortcodes( $text );
$text = apply_filters(‘the_content’, $text);
$text = str_replace(‘]]>’, ‘]]>’, $text);
$excerpt_length = 35; // 35 words
$excerpt_more = apply_filters(‘excerpt_more’, ‘ ‘ . ‘…’);
$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
}
return apply_filters(‘the_excerpt’, $text);
}
It should be as simple as this.
function custom_sub_field_excerpt($field) {
$text = get_sub_field($field);
// the rest of your code
}
You also don’t need to use global $post; in your case since your not using it for anything and ACF automatically does this if you don’t supply a post ID when getting the value of a field.
Hey there. I am having the exact same problem. It is not possible to create a custom excerpt from a sub_field. The solution you suggested won’t work.
This is my code:
function custom_product_excerpt() {
$text = get_sub_field(‘text_left’);
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);
}
The sub field is a WYSIG-Field. I also tried it with a sub field of type textarea. Both don’t work.
Are there any suggestions?
Not sure what I was thinking when I commented the last time. When you your using a sub field you always need to create a loop for the parent field.
if (have_rows('parent_field')) {
while(have_rows('parent_field')) {
the_row();
$text = get_sub_field('sub_field_name');
}
}
The details of what row and sub field you’ll need to work out for yourself, but you cannot use get_sub_field() without creating a loop.
