public function get_loaded_headline( string $key, string $before, string $after, string $fallback = '' )
This method allows you to build headlines and other types of content from loaded post meta more efficiently than by using the get_loaded_meta() method. Before this method is used, load_meta() must be first called to load a specified post's meta into the $loaded_meta property. Otherwise, this method will not function as expected. Loaded meta key values, if set and not empty, are passed through esc_html() and then the format_tags() class method. The primary purpose of this method is to provide a utility for writing more concise code.
(string) (required) The loaded meta key to check and use if is set and not empty.
(string) (required) Markup to include before the processed value of the loaded meta key, if the key is set and not empty, or a fallback value has been provided.
(string) (required) Markup to include after the processed value of the loaded meta key, if the key is set and not empty, or a fallback value has been provided.
(string) (optional) An optional string to fall back to if the loaded meta key isn't set or is empty. If a fallback value is not provided and the key isn't set or is empty, the method will return empty.
For this example, let's imagine that we have a custom post type called
locations. For each location a content editor adds, we've used CMB2 to create a text field (stored as post meta with the key
_method_location_custom_title) that allows content editors to add a custom title for each location. In the example below, we'll build a layout component that loops through each location, checks to see if a custom title has been set, and displays it if available. Otherwise, the post title for the location will be displayed:
