I have moved away from that ‘solution’ and doing this one right now:
function key_value_select( $key ) {
global $wpdb;
$args = array( 'post_type' => 'post' , 'post_status' => 'publish' , 'post_per_page' => -1);
$getposts = get_posts( $args );
foreach($getposts as $post) : setup_postdata($post);
$themeta = get_post_meta($post->ID, $key ,true);
$meta_value = $themeta;
$meta_value .= ' => ';
$meta_value .= $themeta;
$meta_value .= ' , ';
endforeach;
return $meta_value;
}
and in conjuction with the WP Advanced Search framework I get PHP warning >> PHP Warning: array_reverse() expects parameter 1 to be array, string given in …
I have asked at wpas’ support @ github.
Cheers,
Adam
update:
I have inserted :
if(!function_exists(‘add_row’)) {
include(ABSPATH . “wp-content/plugins/advanced-custom-fields-pro/acf.php”);
}
in my custom function but With no effect…
