无法正确连接到wp查询

Question

I am trying to hook into the Cherry Team Members plugin via my child theme's functions.php file and modify the orderby , meta-key , and order to what I want.

I've already successfully accomplished my end goal by editing the plugin files themselves as outlined here by modifying this file specifically , but I know that if I update the plugin, my changes will be lost. Therefore, I would like to be able to hook into this query and make my modifications using the pre_get_posts action so that future plugin updates will not affect this change.

Below is what I've tried in my child theme's functions.php, but I think I am selecting the wrong query, as this code breaks my site.

add_action( 'pre_get_posts', 'modify_team_query' );
function modify_team_query( $query ) {

    // Check if on frontend and main query is modified
    if( ! is_admin() && $query->is_main_query() && $query->query_vars['post_type'] = 'team' ) {

        $query->set('meta_key', 'last_name');
        $query->set('orderby','meta_value title');
        $query->set('order', 'ASC');
    }
}

Does anyone have any suggestions on how to select only the query that happens when I return the [cherry-team] shortcode?

Answer 1

You may just need to remove the $query->is_main_query() . The "main query" is set when WordPress decides what to query for the current Request URI (a certain page, post, category, etc.) - and since this is returned via a shortcode, I'd wager that $query->is_main_query() is returning false.

Also, you're attempting to assign the post type in your if statement:

$query->query_vars['post_type'] = 'team' 

should instead use a comparison operator:

$query->query_vars['post_type'] == 'team'

try to create your function in a separate php file, and include that php file into the plugin main file. keep a backup of this file. So, if your plugin is updated, you only have to add one line of code into the main plugin file to load your custom coded function.
