在 wordpress 的管理面板上更改自定义帖子类型的搜索查询

Question

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() )
        return;

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

    $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%"

Thanks

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

Search term argument of wp_query (ie '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() && $query->query['post_type'] == $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));
    }
    
}

Note:

• I've combined and modified your if statements.
• 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.

Answer 2

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
