Hi everyone @metabox.io,
Hope you all get well !

Just a suggestion, it would be great to add an action/filter before and after the template that output generated php code from the builder, for example to pass som custom functions used in code, or comment, or whatever can extend the generated php code, like so :
```
	private function wrap_function_call() {

        $before = apply_filters('rwmb_before_encoded_string', '');
        $after = apply_filters('rwmb_after_encoded_string', '');
		$this->encoded_string = sprintf(
			'<?php
add_filter( \'rwmb_meta_boxes\', \'%1$s\' );

function %1$s( $meta_boxes ) {
    $prefix = \'%3$s\';
    
    %4$s

    $meta_boxes[] = %2$s;
    
    %5$s

    return $meta_boxes;
}',
			$this->function_name,
			$this->encoded_string,
			$this->prefix,
            $before,
            $after
		);
		return $this;
	}
}
```
so we could call something like :
```
add_filter('rwmb_before_encoded_string', function($string){
   return '$test = \'my lazy test\'; $mycallback = lazy_callback_function();';
});
```
for more improvements and automation.
i really would love it !

have a nice day
Kevin

Hi Kevin,

Thanks for your suggestion.

I will inform the development team to consider supporting those actions in future updates.

Sorry,
have another idea, on the same files here's the final code :
file : wp-content/plugins/meta-box-aio/vendor/meta-box/mbb-parser/src/Encoders/MetaBox.php
```
    private function wrap_function_call() {

        $before = apply_filters('rwmb_mbb_before_php_output', '');
        $after = apply_filters('rwmb_mbb_after_php_output', '');

        $this->encoded_string = sprintf(
            '<?php
add_filter( \'rwmb_meta_boxes\', \'%1$s\' );

function %1$s( $meta_boxes ) {
    $prefix = \'%3$s\';
    %4$s
    
    $this_id = \'%6$s\';
    $meta_boxes[$this_id] = %2$s;
    
    %5$s
    return $meta_boxes;
}',
            $this->function_name,
            $this->encoded_string,
            $this->prefix,
            $before,
            $after,
            $this->settings['id']
        );
        return $this;
    }
```
basically, you could extend the php output for get some variables first (before) and modify the $meta_boxes array by calling it with the $this_id index to some more depending on conditions or whatever you like to. very powerful !

Just a suggestions, as i said, but would be an awesome features for developers.
Have a nice day, and thanks again,
Kevin
