Check if post object exists in repeater

  • Hello, I have a function that adds to a repeater via checkboxes (via ACF Form)

    This works well, except if I update the post then it continually adds the same values.

    See code below. How can I check when I do create the array that the object does not already exist in the repeater? My repeater is field_5ee8874a207d2 and the post object field within this repeater is field_5ee8875b207d3

    function my_save_post_gear_pop( $post_id ) {

    if( get_post_type($post_id) !== ‘trip’) {

    // bail early if editing in admin
    if( is_admin() ) {



    //if( have_rows(‘field_5ee8874a207d2’, $post_id) ) {
    // return;

    // vars
    $post = get_post( $post_id );

    // get custom fields (field group exists for content_form)

    $person_repeater = get_field(‘choices’, $post_id); $countperson = count($person_repeater);
    $post_type = get_post_type($post_id);
    // change to post type you want them to be able to delete
    if ($post_type != ‘trip’) {

    // delete_field(‘field_5ee8874a207d2’, $post_id);
    for($i = 0; $i < $countperson; $i++) {
    $field_key = “field_5ee8874a207d2”;
    $value = get_field($field_key, $post_id);
    $value[] = array(“field_5ee8875b207d3” => “$person_repeater[$i]”);
    update_field( $field_key, $value, $post_id );
    update_field(‘populate_gear_toggle’, NULL, $post_id);


    add_action(‘acf/save_post’, ‘my_save_post_gear_pop’);
