Access repeated fields in PHP hook

    Hello,

    I’m adding custom actions for when the form is submitted (with repeatable fields), but not sure how to retrieve the repeatable fields from the $_POST. Is there a way to loop over the field groups without knowing the total number of groups?

    If I have this in the form:

    
[field_group product-list]
    <label> Product Description (required)
        [text* product-description] </label>
[/field_group]

    How should I loop over all the new entries user has added in PHP:

    
function action_wpcf7_submit( $cf7 ) {

    // loop over entries of product-list?
}
add_action( 'wpcf7_before_send_mail', 'action_wpcf7_submit');

    Thank you,
    Chen

  • Here’s how I did it:

    function action_wpcf7_mail_sent($contact_form)
{
    $submission = WPCF7_Submission::get_instance();
    if ($submission) {
        $posted_data = $submission->get_posted_data();

        $num = $posted_data['_wpcf7_groups_count']['my_field_group_name'];
        for ($i = 1; $i <= $num; $i++){
            echo $posted_data['my_repeater_field_name__'.$i];
        }
    }
}
add_action( 'wpcf7_mail_sent', 'action_wpcf7_mail_sent', 10, 1 );
