Good to hear from you again. Thanks for your question and for including the link to your earlier MLA forum topic.
There are two ways to access [mla_gallery] results, depending on the type of results you want returned. First, you can use the WordPress do_shortcode() function to execute the [mla_gallery] shortcode and return the HTML markup for the gallery display. The second method is more like the function get_results_from_search_mla($queries) example you gave, and is outlined below.
MLA has four supported public functions including one function much like your example. They are defined in the /plugins/media-library-assistant/includes/class-mla-shortcodes.php file. Here is the declaration of the function that might interest you:
/**
* Parses shortcode parameters and returns the gallery objects
*
* Compatibility shim for MLAShortcode_Support::mla_get_shortcode_attachments
*
* @since .50
*
* @param int Post ID of the parent page/post or zero
* @param array Attributes of the shortcode
* @param boolean Optional; true to calculate and return ['found_posts'] as an array element
* @param boolean Optional; true activate debug logging, false to suppress it.
*
* @return array WP_Post[]|int[] Array of post objects or post IDs.
*/
public static function mla_get_shortcode_attachments( $post_parent, $attr, $return_found_rows = NULL, $overide_debug = NULL ) {
This function is used in the following MLA Example plugins, where you can see how it is used:
- MLA Gallery Download Archive
- MLA Multi-search Example
- MLA Multiple WP Query Example
- MLA Parent Search Example
- MLA Custom Feed Example
- MLA Multisite Extensions
- MLA UI Elements Example
The $attr parameter accepts an array of shortcode parameters as defined in the Documentation tab for the shortcode, e.g., $attr = array( 'post_parent => 'all', 'post_mime_type' => 'application/pdf' );
The default return value of the function is an array of WP_Post objects, but you can add fields=ids to the attributes to get just the ID values of the selected items.
I will be adding more of this information to the Documentation tab, but that should get you started. I will leave this topic unresolved in case you have problems or further questions regarding the above suggestions. Thanks for your continued interest in the plugin.
