What is a Meta Query?
Ideally, a Meta query is an array of conditions, which specifically says which posts to retrieve based on their metadata. Now, you can add each condition, such as meta_key, meta_value, and meta_compare.
Here’s what they mean:
- meta_key: The custom field you’re searching for.
- meta_value: The value associated with that custom field.
- meta_compare: Specifies how the value should be compared (e.g.,
=,!=,LIKE).
Use of WordPress Search Query with Meta Query
Here is the code:
add_action( 'pre_get_posts', function( $query ) {
global $pagenow;
if ( 'edit.php' === $pagenow && isset($_GET['post_type']) && 'shop_order' === $_GET['post_type'] ){
$meta_key = 'source_name';
$search_key = $query->get('s');
if( $search_key ){
$query->set('s', '' );
add_filter( 'get_meta_sql', function( $sql ) use ( $search_key ){
global $wpdb;
// Only run once:
static $nr = 0;
if( 0 != $nr++ ) return $sql;
// Modified WHERE
$sql['where'] = sprintf(
" AND ( %s OR %s ) ",
$wpdb->prepare( "{$wpdb->posts}.post_title like '%%%s%%'", $search_key),
mb_substr( $sql['where'], 5, mb_strlen( $sql['where'] ) )
);
return $sql;
});
$meta_query = $query->get( 'meta_query' );
if( $meta_query) {
$meta_query[] = array(
'key' => $meta_key,
'value' => $search_key,
'compare' => 'LIKE',
);
}else{
$meta_query = array(
'relation' => 'OR',
array(
'key' => $meta_key,
'value' => $search_key,
'compare' => 'LIKE',
)
);
}
$query->set( 'meta_query', $meta_query );
