Compounding on Saving metabox repeatable fields ...
I've created a metabox with a series of fields that are repeatable. However, within those fields, I'd like to create another field named Choices and make that repeatable within each grouping.
I was able to setup the additional field and repeat it, but have no idea how to save the value of the new repeatable field. The new field that I was trying to create is within the commented portions of the code below as well as my attempts at saving it
function poll_potential_results() {
$options = array (
'Option 1' => 'option1',
'Option 2' => 'option2',
);
return $options;
}
add_action('admin_init', 'poll_add_metaboxes', 1);
function poll_add_metaboxes() {
add_meta_box( 'Dicey', 'Questions and Options', 'poll_metabox', 'quizzes', 'normal', 'default');
}
function poll_metabox() {
global $post;
$repeat_fields = get_post_meta($post->ID, 'repeat_fields', true);
$options = poll_potential_results();
wp_nonce_field( 'poll_metabox_nonce', 'poll_metabox_nonce' );
?>
<script type="text/javascript">
jQuery(document).ready(function( $ ){
$( '#add-row' ).on('click', function() {
var row = $( '.empty-row.screen-reader-text' ).clone(true);
row.removeClass( 'empty-row screen-reader-text' );
row.insertAfter( '#repeatable_row' );
return false;
});
$( '.remove-row' ).on('click', function() {
$(this).parents('tr').remove();
return false;
});
/*$('#add-choice' ).on('click',function() {
var choicenew = $(this).closest('tr' ).clone(true);
var choice = $(this ).closest('tr');
choicenew.insertAfter(choice);
return false;
})*/
});
