First, Lets find out what version of PHP we're running (To find out if it's the default version).
To do that, Within the terminal, Fire this command:
which php
| .p-0 { | |
| padding: 0px; | |
| } | |
| .p-3 { | |
| padding: 3px; | |
| } | |
| .p-5 { | |
| padding: 5px; | 
| <?php | |
| add_action('admin_init', 'add_meta_boxes', 1); | |
| function add_meta_boxes() { | |
| add_meta_box( 'repeatable-fields', 'Audio Playlist', 'repeatable_meta_box_display', 'post', 'normal', 'high'); | |
| } | |
| function repeatable_meta_box_display() { | |
| global $post; |
