I use a repeating field in a CPT. What I would like to be able to do, is to use a parametric search to search for the number of repeating fields. Something like:
list the posts with a number of repeating fields between x and y
list the posts with a number of repeating fields of a maximum of x, etcetera
I know how to set up a search like this for non-repeating fields, but how do I do this with repeating fields?
Yes, that is what I would like to do. Not for images, but for other content, but it is the same principle. Could a solution be the following?
- count the number of fields when saving the CRED-form and write the result as a number to a separate field, using the cred_save_data hook?
- then I could use this number in the separate field for the search filters
If this would be the right direction, how could I do it? I found the following snippet on the forums to count the number of repeated fields as a shortcode, but I struggle to rewrite it to use it for the cred_save_data hook.
// shortcode to count number of repeating field instances
add_shortcode( 'count-repeat', 'count_repeat_func' );
function count_repeat_func($atts) {
return sizeof(get_post_meta( get_the_ID(), 'wpcf-' . $atts['field'], false ));
// shortcode to count number of repeating field instances
add_shortcode( 'count-total', 'count_repeat_func' );
function count_repeat_func($atts) {
return sizeof(get_post_meta( $atts['post-id'], 'wpcf-' . $atts['field'], false ));
}
So what you need to do is add the following to your functions.php file and it should create a new custom field with the count inside it.
add_action('cred_save_data', 'my_save_data_action',10,2);
function my_save_data_action($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==12)
{
$count = sizeof(get_post_meta( $post_id, 'wpcf-field', false ));
// add it to saved post meta
add_post_meta($post_id, 'my_count', $count, true);
}
}
Now what you need to do is just replace the wpcf-field with the name of the Types field you want to check and change the 12 to the id of you form.
