Specify number of Repeater fields

Is there any way to specify the number of repeater fields on the front-end?

I’m able to successfully display a repeater field on the front-end allowing users to enter values but I don’t want them to be able to enter as many as they want or as few as they want. I want to specify exactly how many.

Is this possible?

Hi @moonshdw8

You can limit the number of rows to be added to the repeater by setting the maximum rows option from the field group edit page.

Hope this helps.

Thanks a lot for the quick reply, but I want to be able to do this programatically.
In this case, if someone has, let’s say 15 items. I want to display 15 repeater fields.
Or 5 items, 5 repeater fields. etc.

Thanks again.

Incidentally, this is my existing code

acf_form(array(
   'fields' => array('field_5d366cc2c5656'),
));

For anyone else with this issue, I resolved it this way:
I used the acf/load_value as outllined here: https://gist.github.com/theJasonJones/7061b8020e43a114756214e20c4d0ed9

Fantastic Help!
Instead of adding each item like they do int he tutorial, I had a global variable based on how many items I needed, then I looped through the “$value[] = array(…” creating as many repeater items as I need.
Here’s my resultant code:

// Sets the number of Repeater Confirm Ring Size items.
add_filter('acf/load_value/key=field_5d366cc2c5656',  'afc_load_my_repeater_value', 10, 3);
function afc_load_my_repeater_value($value, $post_id, $field) {
    global $ring_count;
    //Optional: Check for post_status otherwise published values will be changed.
    if ( get_post_status( $post_id ) === 'wc-processing' or get_post_status( $post_id ) === 'wc-pending') {
         //Optional: Check for post_type.
        if( get_post_type( $post_id ) == 'shop_order' ){
            if ($ring_count > 0){
                $value	= array();
                // Add field key for the field you would to put a default value (text field in this case)
                for ($i = 0; $i < $ring_count; $i++) {
                    $value[] = array(
                        'field_5d366d10c5657' => '5'
                    );
                }
            }
        }
    }
    return $value;
}
