Я испытал то же самое, и добавление следующего блока кода в мой файл functions.php
немедленно исправило это:
function m_request_query( $query_vars ) {
global $typenow;
global $wpdb;
global $pagenow;
if ( 'product' === $typenow && isset( $_GET['s'] ) && 'edit.php' === $pagenow ) {
$search_term = esc_sql( sanitize_text_field( $_GET['s'] ) );
// Split the search term by comma.
$search_terms = explode( ',', $search_term );
// If there are more terms make sure we also search for the whole thing, maybe it's not a list of terms.
if ( count( $search_terms ) > 1 ) {
$search_terms[] = $search_term;
}
// Cleanup the array manually to avoid issues with quote escaping.
array_walk( $search_terms, 'trim' );
array_walk( $search_terms, 'esc_sql' );
$meta_key = '_sku';
$post_types = array( 'product', 'product_variation' );
$query = "SELECT DISTINCT posts.ID as product_id, posts.post_parent as parent_id FROM {$wpdb->posts} posts LEFT JOIN {$wpdb->postmeta} AS postmeta ON posts.ID = postmeta.post_id WHERE postmeta.meta_key = '{$meta_key}' AND postmeta.meta_value IN ('" . implode( "','", $search_terms ) . "') AND posts.post_type IN ('" . implode( "','", $post_types ) . "') ORDER BY posts.post_parent ASC, posts.post_title ASC";
$search_results = $wpdb->get_results( $query );
$product_ids = wp_parse_id_list( array_merge( wp_list_pluck( $search_results, 'product_id' ), wp_list_pluck( $search_results, 'parent_id' ) ) );
$query_vars['post__in'] = array_merge( $product_ids, $query_vars['post__in'] );
}
return $query_vars;
}
add_filter( 'request', 'm_request_query', 20 );
Привет Мирциан для фрагмента.
