asp_query_args

The asp_query_args filter provides a possibility to add/remove/change query arguments right before they are passed to the ajax search pro main query.

This filter is executed after the search options were processed!

// Classic Usage
add_filter("asp_query_args", "asp_query_args_change", 10, 2);
function asp_query_args_change($args, $search_id) {
  // Do your stuff with the $args array
  // ....  
  // Then return
  return $args;
}

// Shorter version with type safety and anonymous function
use WPDRMS\ASP\Models\SearchQueryArgs;
add_filter("asp_query_args", function(SearchQueryArgs $args, int $search_id) {
  return $args;
}, 10, 2);

Parameters

• $args (SearchQueryArgs) - the object of the arguments (structure detailed in chapter below). This object implements the ArrayAccess interface in a way that all of it's properties are accessible as array keys as well.

• $search_id (int) - the current search ID

Example: Explicitly changing the post types and post fields to search

// Classic Way
add_filter("asp_query_args", "asp_query_args_change", 10, 2);
function asp_query_args_change($args, $search_id) {
  // Changing post types to post and page
  $args['post_type'] = array('post', 'page');
  // Search only title and content
  $args['post_fields'] = array('title', 'content');

  return $args;
}

// Shorter version with type safety and anonymous function
use WPDRMS\ASP\Models\SearchQueryArgs;
add_filter("asp_query_args", function(SearchQueryArgs $args, int $search_id) {
  $args->post_type = array('post', 'page');
  $args->post_fields = array('title', 'content');
  return $args;
}, 10, 2);

Accepted Properties of the $args object

For the complete $args source list with type hints and accepted values please check: wp-content/plugins/ajax-search-pro/includes/classes/Models/SearchQueryArgs.php

The $args object is the heart and soul of this filter. By changing it's key values you can directly affect the search outcome.

The default values of the key arguments depend on the search intance configuration and the passed arguments from the front-end before the search process.

It is recommended to treat the $args variable as SearchQueryArgs object instad of an array to get type hints in your editor.
