The intended width of the pattern to allow for a scaled * preview within the pattern inserter. * @type bool $inserter Optional. Determines whether the pattern is visible in inserter. * To hide a pattern so that it can only be inserted programmatically, * set this to false. Default true. * @type string[] $categories Optional.

A list of aliases or keywords that help users discover * the pattern while searching. * @type string[] $blockTypes Optional. A list of block names including namespace that could use * the block pattern in certain contexts (placeholder, transforms). * The block pattern is available in the block editor inserter * regardless of this list of block names. * Certain blocks support further specificity besides the block name * (e.g. for `core/template-part` you can specify areas * like `core/template-part/header` or `core/template-part/footer`). * @type string[] $postTypes Optional. An array of post types that the pattern is restricted * to be used with. The pattern will only be available when editing one * of the post types passed on the array. For all the other post types * not part of the array the pattern is not available at all. * @type string[] $templateTypes Optional. An array of template types where the pattern fits. * @type string $filePath Optional. The full path to the file containing the block pattern content. * } * @return bool True if the pattern was registered with success and false otherwise. */ public function register( $pattern_name, $pattern_properties ) { if ( ! isset( $pattern_name ) || ! is_string( $pattern_name ) ) { _doing_it_wrong( __METHOD__, __( 'Pattern name must be a string.' ), '5.5.0' ); return false; } if ( ! isset( $pattern_properties['title'] ) || ! is_string( $pattern_properties['title'] ) ) { _doing_it_wrong( __METHOD__, __( 'Pattern title must be a string.' ), '5.5.0' ); return false; } if ( ! isset( $pattern_properties['filePath'] ) ) { if ( ! isset( $pattern_properties['content'] ) || ! is_string( $pattern_properties['content'] ) ) { _doing_it_wrong( __METHOD__, __( 'Pattern content must be a string.' ), '5.5.0' ); return false; } } $pattern = array_merge( $pattern_properties, array( 'name' => $pattern_name ) ); $this->registered_patterns[ $pattern_name ] = $pattern; // If the pattern is registered inside an action other than `init`, store it // also to a dedicated array.
