 * Hi there
 * I’m using ACF and i’m quite impressed. But one major feature request would be
   to allow PHP in the Default Value field.
 * Example:
    I need a custom field with the post’s slug as default value, and this
   would be easy to fill in with something like
 *     ```
       <?php $slug = $post->post_name;
       echo $slug;>
       ```
   
 * Could you please consider this?

 * Did you ever find a way to do this?

 * No, sadly not.

 * You could use a filter of ACF via your theme `functions.php`, something like 
   this:
 * A field named `my_field`, insert name at `name=` in `add_filter()` line.
 * A default value of `php_default_hack` for that field.
 *     ```
       function my_acf_load_value( $value, $post_id, $field ) {
       	if ( $value == 'php_default_hack' ) {
       		// do your php magic here...
       		$value = 'this is set from php';
       	}
       	return $value;
       }
       add_filter( 'acf/load_value/name=my_field', 'my_acf_load_value', 10, 3 );
       ```
   
 * The code does this: If your field has the value `php_default_hack` during load,
   the value will be replaced by `this is set from php`.
 * See also [http://www.advancedcustomfields.com/resources/filters/acfload_value/](http://www.advancedcustomfields.com/resources/filters/acfload_value/)
 * For your example, note that a new created post has no slug = post_name yet.
