By leveraging these hooks, you can ensure that YM Fast SEO grows with your website, providing you with the flexibility and control necessary for optimal performance.

Actions

ymfseo_after_print_metas

If you need to print specific meta tags or any other content in the <head> section, you can use the ymfseo_after_print_metas hook. Simply write the necessary output in its callback function, and the elements will be displayed at the end of the YM Fast SEO output.


// Prints additional meta tags.
add_action( 'ymfseo_after_print_metas', function () {
	echo '<meta name="twitter:domain" content="yanmet.com">';
});

Filters

ymfseo_title_separator

If none of the separators offered in the settings suit you, you can set a custom value using this filter.


/**
 * Modifies YM Fast SEO separator symbol.
 *
 * @param string $sep Separator symbol.
 *
 * @return string
 */
add_filter( 'ymfseo_title_separator', function ( string $sep ) : string {
	$sep = '<>';

	return $sep;
});

ymfseo_tags

If you want to add custom tags to use in meta fields, you can use the following filter:


/**
 * Modifies YM Fast SEO replace tags list.
 * 
 * @param array $tags Replace tags list.
 * 
 * @return string
 */
add_filter( 'ymfseo_tags', function ( array $tags ) : array {
	$tags = array_merge( $tags, [
		'%my_tag%' => 'My replace string',
	]);
	
	return $tags;
});

ymfseo_meta_fields

You can also modify the raw data values, which are later used to generate basic meta tags and other elements.

The ymfseo_meta_fields filter passes an associative array that you can modify by applying your own logic. It’s crucial to perform a type check on the query object before making changes, as the same ID might be associated with different post records or taxonomy terms.


/**
 * Modifies YM Fast SEO meta fields.
 *
 * Sets ACF field value as default meta description
 * for custom post type.
 *
 * @param array $meta_fields Meta fields array.
 * @param WP_Post|WP_Post_Type|WP_Term|WP_User|null $queried_object Queried object.
 *
 * @return array
 */
add_filter( 'ymfseo_meta_fields', function ( array $meta_fields, $queried_object ) : array {
	// Exit if `$queried_object` is null.
	if ( is_null( $queried_object ) ) {
		return $meta_fields;
	}

	/*
	 * `$queried_object` can be of `WP_Post`, `WP_Post_Type`,
	 * `WP_Term`, and `WP_User` class.
	 */
	switch ( get_class( $queried_object ) ) {
		case 'WP_Post':
			if ( 'product' == $queried_object->post_type ) {
				if ( empty( $meta_fields[ 'description' ] ) ) {
					$meta_fields[ 'description' ] = esc_attr( get_field( 'description', $post->ID ) );
				}
			}
			
			break;
	}

	return $meta_fields;
}, 10, 2 );

ymfseo_schema_org

The ymfseo_schema_org filter is applied to modify or add new Schema.org entities and parameters.


/**
 * Modifies Schema.org JSON-LD.
 *
 * @param array $schema_org Schema.org data array.
 * @param WP_Post|WP_Post_Type|WP_Term|WP_User|null $queried_object Queried object.
 *
 * @return array
 */
add_filter( 'ymfseo_schema_org', function ( array $schema_org, $queried_object ) : array {
	// Exit if `$queried_object` is null.
	if ( is_null( $queried_object ) ) {
		return $schema_org;
	}

	// Modificate here.

	return $schema_org;
}, 10, 2 );
