# Reset the query within plugin

 * Hi all,
 * I’m working on a new plugin but i came across a very frustrating issue.
    I register
   several metaboxes and in a few of them i use a query. Now to get my metavalue
   for the other metaboxes i use `get_post_meta($post->ID,'_social',TRUE);` However
   the metabox with the query in it somehow resets the $post variable. And i can’t
   reset the query with `wp_reset_query()`. I’ve tried all kinds of querying and
   unset methods. But none of them seem to work.
 * My file structure is like this:
    - wp-stagemanager.php
    - admin(folder)
 *  - artists.php
    - events.php
    - metaboxes.php
 *  - assets(folder)
 *  - css(folder)
    - img(folder)
    - js(folder)
 *  - cache(folder)
 *  - data.json
 *  - front(folder)
 *  - functions.php
 * in wp-stagemanager.php i include the admin/metaboxes.php which has the following
   code…
 *     ```
       <?php
       add_action('admin_init', 'WPSM_add_metabox', 1);
       add_action('save_post', 'WPSM_save_metabox');
   
       function WPSM_add_metabox() {
           add_meta_box( 'WPSM_meta_social', __( 'Social Media', 'wp-stagemanager_textdomain' ),
           			'WPSM_init_meta_social', 'artist' );
   
          	add_meta_box( 'WPSM_meta_datetime', __( 'Event Date & Time', 'wp-stagemanager_textdomain' ),
          				'WPSM_init_meta_datetime', 'event');
   
       	add_meta_box( 'WPSM_meta_tickets', __( 'Event Tickets', 'wp-stagemanager_textdomain' ),
       				'WPSM_init_meta_tickets', 'event' );
   
       	add_meta_box( 'WPSM_meta_artists', __( 'Event Artists', 'wp-stagemanager_textdomain' ),
       				'WPSM_init_meta_artists', 'event' );
       }
   
       function WPSM_init_meta_social(){
         global $post;
   
         $social = get_post_meta($post->ID,'_social',TRUE);
         $socialnonce = wp_create_nonce(__FILE__);

       ```
   
 * Is this a scope issue? When i use a function_exsists on the wp_reset_query() 
   it turns out true.
 * I hope you guys can help cause i’m really stuck here.
    Thanks!
 * Cheers,
    R.
