WP_Block_Type::render() WordPress Method

The WP_Block_Type::render() method is used to render a given block type. This is done by running the block type's render_callback() method, if it exists. If the render_callback() method doesn't exist, the method will fall back to rendering the block type's save() method return value.

WP_Block_Type::render( array $attributes = array(), string $content = '' ) #

	public function render( $attributes = array(), $content = '' ) {
		if ( ! $this->is_dynamic() ) {
			return '';
		}

		$attributes = $this->prepare_attributes_for_render( $attributes );

		return (string) call_user_func( $this->render_callback, $attributes, $content );
	}
