請問我有一個註冊表格，我讓它user_login欄位不小於11 個字才可以註冊，我使用cred_form_validate，但放入funtion.php之後，在註冊的時候，輸入超過或等於11個字的時候errors還是會出現訊息，請我的code是否有需要調整的?謝謝

//手機號不小於11個字元
add_filter( 'cred_form_validate', 'tssupp_custom_validation', 10, 2 );
function tssupp_custom_validation( $error_fields, $form_data ) {
   
    //field data are field values and errors
    list( $fields,$errors ) = $error_fields;
   
    //validate if specific form
    if ( $form_data['id'] == 49 ) {
   
        if ( isset( $fields['user_login']['value'] ) && str_word_count( $fields['user_login']['value'] ) < 11 ) {
   
            $errors['user_login'] = '请输入不小于11个字的电话号码';
        }
   }
   
    return array( $fields,$errors );
}

你好，

你是用了 function str_word_count()，它是用來計算句子裏面出現的詞語數量，我建議你使用的是另外一個function：mb_strlen()來計算字符數量，例如替換這一行

if ( isset( $fields['user_login']['value'] ) && str_word_count( $fields['user_login']['value'] ) < 11 ) {

為：

if ( isset( $fields['user_login']['value'] ) && mb_strlen( $fields['user_login']['value'] ) < 11 ) {
