Change search query of a custom post type on the admin panel in wordpress

I want to change the query of search a custom post type in wordpress admin panel. I use this method:

function change_admin_search( $query ) {

    $post_type = 'custom_post_type';

    if( ! is_admin() )

    if ( $query->query['post_type'] != $post_type )

    $search_term = $query->query_vars['s'];
    $persian = ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'];
    $num = range(0, 9);
    $persianNumbersOnly = str_replace( $num,$persian, $search_term);
    $englishNumbersOnly = str_replace( $persian, $num, $search_term);
    $query->query_vars['s'] = $englishNumbersOnly;

add_action( 'pre_get_posts', 'change_admin_search' );

In this query, it search only with $englishNumbersOnly. I want to search with $englishNumbersOnly OR $persianNumbersOnly, and $query->query_vars['s'] have a OR in query. Actually have a query like this :

post Like "%$englishNumbersOnly%" OR post Like "%$persianNumbersOnly%"

    I found the solution in WP_Query::parse_search method. As @Ruvee says, we can use '+' sign to feed more than one search term for 's' argument, But In parse_search method, the $searchand value is ' AND ' and it ands search_terms. I Customize parse_search for custom_post_type to use OR instead of AND

    "I want to show all result ( persian and english )"

    Search term argument of wp_query (i.e 's') accepts more than one keyword/term. The way you could feed it more than one keyword is to use + sign in the middle of the keywords, and it should be a string not an array. Like this:

    • $query->set( 's' => 'keywordOne+keywordTwo+keywordThree' )

    We could use this to modify your query:

    add_action('pre_get_posts', 'change_admin_search');
    function change_admin_search($query)
        $post_type = 'custom_post_type';
        if (is_admin() && in_array($query->get('post_type'), array($post_type))) {
            $search_term = sanitize_text_field($query->query_vars['s']);
            $persian = ['۰', '۱', '۲', '۳', '۴', '۵', '۶', '۷', '۸', '۹'];
            $num = range(0, 9);
            $persianNumbersOnly = str_replace($num, $persian, $search_term);
            $englishNumbersOnly = str_replace($persian, $num, $search_term);
            $query->set('s',  strval($englishNumbersOnly) . '+' . strval($persianNumbersOnly));


    • I've combined and modified your if statements.
    • I've changed your "post type" conditional check so that you could use more than one post type.
    • I've used sanitize_text_field function on the searched keyword.
    • I've used set method for setting the s value.
    • Using strval function is not necessary, but I've used it to make sure you don't get any error(s)/warning(s).

    This has not been tested but, theoretically, it should work. Let me know if you could get it to work.
