 * I’m using[ this code](http://www.kevinleary.net/get-all-custom-fields-attached-post-page-post-type/)
   here to grab all my custom fields from a post for use in an gallery array.
 * function:
 *     ```
       //  Get all custom fields attached to a page
       if ( !function_exists('base_get_all_custom_fields') ) {
       function base_get_all_custom_fields()
       {
           global $post;
           $custom_fields = get_post_custom($post->ID);
           $hidden_field = '_';
           foreach( $custom_fields as $key => $value ){
               if( !empty($value) ) {
                   $pos = strpos($key, $hidden_field);
                   if( $pos !== false && $pos == 0 ) {
                       unset($custom_fields[$key]);
                   }
               }
           }
           return $custom_fields;
       }
       }
       ```
   
 * single.php:
 *     ```
       // Get all custom fields attached to this post and store them in an array
       $custom_fields = base_get_all_custom_fields();
       if( !empty($custom_fields) ) {
       print_r($custom_fields);
       }
       ```
   
 * It works, but outputs text like this around the custom post: _Array ( [photo1]
   => Array ( [0] =>_
 * Is there a way to customise what you wrap before & after a custom field output,
   and remove the array text? I ‘m not a php expert.
 * What I’m trying to achieve is
 *     ```
       {image : 'http://website.com/slides/photo1.jpg'},
       {image : 'http://website.com/slides/photo2.jpg'},
       {image : 'http://website.com/slides/photo3.jpg'},
       ```
   
 * so I need to wrap {image : ‘ before and ‘}, after the link.
 * I can sort of do it with single queries but the array system would be better
 *     ```
       {image : '<?php echo $custom_fields['photo1'][0]; ?>'},
       {image : '<?php echo $custom_fields['photo2'][0]; ?>'},
       {image : '<?php echo $custom_fields['photo3'][0]; ?>'},
       ```

 * The print_r() function just dumps out the contents of a variable. To format as
   you showed in your sample, you will need to have a foreach loop to process each
   link:
 *     ```
       // Get all custom fields attached to this post and store them in an array
       $custom_fields = base_get_all_custom_fields();
       if( !empty($custom_fields) ) {
          $sep = '';
          foreach ($custom_fields as $key => $value) {
             echo "$sep{image : '$value'};
             $sep = ",\n";
          }
       }
       ```
