Both Types,

I have a country dropdown that needs to be populated by a “country” post_type and a “specialisation” dropdown that needs to be populated from a meta_value.

I’m currently using jQuery but would be happier if there was a built in filter, function or hook.

This is my current jquery and php for the country dropdown.

<?php
 // query for your post type
$post_type_query  = new WP_Query(  
	array (  
		'post_type'		=> 'country',  
		'posts_per_page'	=> -1 , 
		'orderby'		=> 'title',
		'order'			=> 'ASC',
	)  
);   
// we need the array of posts
$posts_array = $post_type_query->posts;   
// create a list with needed information
// the key equals the ID, the value is the post_title
$post_title_array = wp_list_pluck( $posts_array, 'post_title', 'post_name' );
//echo '<pre>' . var_export(json_encode($post_title_array), true) . '</pre>';
?>

<script>
(function($) {
	var selectValues = <?php echo json_encode($post_title_array); ?>;
	var selectMenu = $('#country-select');

	$.each(selectValues, function(key, value) {
		selectMenu
		  .append($('<option>', { value : key })
		  .text(value));
	});
})(jQuery);
</script>

I’ve tried adding “‘raw’ => true” to the metabox type=text and it still fails.

Embarrasingly the post only had a single paragraph tag, so that was all it was showing…

I added some more styles and BOOM! Works like a charm.

Thanks but I tried the plug-in’s but couldn’t get any to work!
