The comments_template_query_args hook in WordPress is a filter that allows developers to modify the query arguments used to retrieve comments when the comments template is loaded on a page.
By default, when the comments_template() function is called in a WordPress theme file, it retrieves the comments for the current post based on a set of default query arguments. However, there may be cases where a developer wants to modify these arguments, for example, to change the order in which comments are displayed or to exclude certain types of comments.
The comments_template_query_args hook provides a way for developers to modify these arguments to fit their specific needs. When the hook is called, it passes an array of query arguments as a parameter, which can be modified and returned to override the default arguments.
Example Usage:
// Modify the comments query to exclude pingbacks and trackbacks function my_comments_filter( $query_args ) { $query_args[‘type__not_in’] = array( ‘pingback’, ‘trackback’ ); return $query_args; } add_filter( ‘comments_template_query_args’, ‘my_comments_filter’ );
In this example, we’re using the comments_template_query_args hook to modify the query arguments used to retrieve comments when the comments template is loaded. Specifically, we’re excluding pingbacks and trackbacks from the comments query by adding the ‘type__not_in’ argument to the array and then returning the modified array. This allows us to customize the behavior of the comments template to better suit our needs.
