【问题描述】：

我不熟悉 PHP，但尝试在 theme/functions.php 中插入代码 sn-p。我的目的是根据事件自定义帖子类型和自定义字段查询一些帖子。

add_action( 'elementor/query/events', function( $query ) {
  $args = array(
            'post_type' => 'event',
            'meta_query' => array(
              array(
                  'key' => 'dstart',
                  'type' => 'DATE',
                  'value' => date('Y-m-d'),
                  'compare' => '>'            
              ),
            ),         
  );
$query->set($args);
} );

但它有这样的错误：

Uncaught ArgumentCountError: Too few arguments to function WP_Query::set(), 1 passed in wp-content/themes/hello-theme-child-master/functions.php on line 46 and exactly 2 expected in wp-includes/class-wp-query.php:1752
Stack trace:

#5 wp-includes/class-wp-hook.php(292): ElementorPro\Modules\QueryControl\Classes\Elementor_Post_Query->pre_get_posts_query_filter(Object(WP_Query))

我能知道我误解了哪些部分吗？谢谢。

【解决方案1】：

我想出了怎么做：

add_action( 'elementor/query/event', function( $query ) {
    // Here we set the query to fetch posts with
    // post type of 'custom-post-type1' and 'custom-post-type2'
    $query->set( 'post_type', [ 'event' ] );
    
    $meta_query = $query->get( 'meta_query' );

    // If there is no meta query when this filter runs, it should be initialized as an empty array.
    if ( ! $meta_query ) {
        $meta_query = [];
    }

    // Append our meta query
    $meta_query[] = [
        'key' => 'dstart',
        'type' => 'DATE',
        'value' => date('Y-m-d'),
        'compare' => '>',
    ];
    $query->set( 'meta_query', $meta_query );
    
    
} );
