Hooks

Slim SEO Link Manager provides some hooks for developers to extend the functionality of the plugin.

Filters​

slim_seo_link_manager_post_types​

This filer allows you to ignore some post types when scanning links. It accepts one parameter - an array of allowed post type objects (with key is the post type slug and value is the post type object) and returns an array.

add_filter( 'slim_seo_link_manager_post_types', function ( $post_types ) {
    unset( $post_types['movies'] );
    return $post_types;
} );

This filter allows you to change the post query for getting suggested posts.

add_filter( 'slim_seo_link_manager_link_suggestions_args', function( $args ) {
    $args['cat'] = 12;
    return $args;
} );

This filter allows you to change the post query for searching posts.

add_filter( 'slim_seo_link_manager_search_args', function( $args ) {
    $args['cat'] = 12;
    return $args;
} );

slim_seo_link_manager_post_custom_fields​

This filter allows you to add custom fields' content to the plugin's scanner.

add_filter( 'slim_seo_link_manager_post_custom_fields', function( $fields ) {
    $fields[] = 'my-text-field';
    return $fields;
} );

After running this filter, the plugin will get the content of the custom field (in the example above, the meta key of the custom field is my-text-field) and analyze that content to find links and add to the reports.

This filter allows you to bypass a URL, e.g. not including it in the reports. It's helpful if you want to keep the reports clean and don't want it to contain links like affiliate links.

add_filter( 'slim_seo_link_manager_process_url', function( $process, $url ) {
    if ( strpos( $url, 'amz.co' ) !== false ) {
        $process = false;
    }
    return $process;
} );
