### Change Meta Description via Filter - Avoid Overwriting Manual Input

Source: https://docs.wpslimseo.com/slim-seo/meta-description-tag

This filter prevents overwriting a manually entered meta description. It checks if a manual description exists in the 'slim_seo' meta data before applying a custom description from the 'movie_desc' custom field for 'movie' post types.

```php
add_filter( 'slim_seo_meta_description', function ( $description, $object_id ) {

    if ( get_post_type( $object_id ) === 'movie' ) {

		// Detect if a single post has manual meta description.

        $slim_meta = get_post_meta( $object_id, 'slim_seo', true );

        if ( ! empty( $slim_meta['description'] ) ) {

            return $slim_meta['description'];

        }

  

        $description = get_post_meta( $object_id, 'movie_desc', true );

    }

  

    return $description;

}, 10, 2 );
```
