Why the cloned value won't save in DB ? It's working fine for the first row (not the cloned one) but when I add new value with jQuery(.clone), new added value won't save...

jQuery

$('#add-embed').on('click', function() {
    var row = $('.empty-row').clone(true);
        row.removeClass('empty-row').addClass('entries');
        row.insertBefore('#repeater > div:last');
    return false;
});

HTML

<div id="repeater">
    <div class="entries">
        <input type="text" name="al_ttl[]">
        <input type="text" name="al_tmp[]">
    </div>
    <div class="empty-row">
        <input type="text" name="al_ttl[]">
        <input type="text" name="al_tmp[]">
    </div>
</div>

Save

function frontend_submit() {
    global $current_user, $post;

    if ( 'POST' == $_SERVER['REQUEST_METHOD']
        && !empty( $_POST['action'] )
        && $_POST['action'] == 'post' ) {

        //Global Post
        $post_id        = $post->ID;
        $user_id        = $current_user->ID;
        $post_title     = $_POST['post_title'];


        $post_id = wp_insert_post(array(

            'post_status'   => 'publish',

• I didn't read every line of code, but I'm pretty confused as to what is going on here. What are you trying to achieve? – jasonp Commented Jan 7, 2020 at 18:38

• 1 is your <div id='repeater'> properly inside <form> tag of your page ( I assume you're in a form since your code does not provide an ajax function) – Andrea Somovigo Commented Jan 13, 2020 at 8:49

1 Answer 1

Double check if your <div id='repeater'> is properly inside <form> tag of your page ( I assume you're in a form since your code does not provide an ajax function) and from what you outpup with var_dump($_POST['al_ttl']) it may be the reason of Undefined index: al_ttl.

Also note that you're overwriting the first initialization of $post_id with wp_insert_post and after that you're looking for a post_meta $old = get_post_meta($post_id, 'data_rows', true); which will always be empty being on the new post
