Adding to $count with ACF flexible content

  • I have a flexible content template for single-news.php that includes a repeater. How do I add up all the reading time for that post?
    I need to get the count of words for get_sub_field(‘content’)—there may be multiple instances of it (i’ve removed other row layouts for readability). Here is the code that is in the template I am hoping to get a count of.

    if(have_rows('panels')):
	while(have_rows('panels')) : the_row();
	if(get_row_layout() == 'content'):
			$output .= '<section class="row clearfix">';
			$output .= get_sub_field('content');		
endif;
	endwhile;

echo $output;
endif;

    Any ideas? I know there is a way to use this filter, but i can’t quite figure it out:
    add_filter( 'rtwp_filter_wordcount', 'up_the_count' );

    Thanks!

    You would use the filter to run a function that gets your field, counts the words, and adds that to the word count.

    function up_the_count( $count ) {
    // Gets the word count of your sub field named 'content'
    $field_count = count( preg_split( '/\s+/', get_sub_field( 'content' ) );

    $count += $field_count;

    return $count;
}

add_filter( 'rtwp_filter_wordcount', 'up_the_count' );

    You’d want to make sure you only run that when the page is using that particular template. You could do that with a conditional check.

    And just wanted to note, I didn’t fully test that code, just wrote it here for the comment. Let me know if you have any issues.

    It is still just returning ‘1’. Could it be an issue that it isn’t looping through all instances of the ‘content’ subfield? for any given post we might have 5 content modules, and I think this is just taking just one into consideration?

    Ah yes, in that case you’d probably need to wrap the line $field_count = count( preg_split( '/\s+/', get_sub_field( 'content' ) ); and $count += $field_count; in the repeater looping functionality. That should loop through and get all fields. You may need to make sure you’re passing the proper post id as well as a parameter to the get_sub_field if it isn’t returning your data.

    @bcook3 was wondering if you got this working? I am running into the same issue!
