你可以挂到wp_login_errors 滤器
add_filter(\'wp_login_errors\', function($errors, $redirect_to){
if(isset($errors->errors[\'incorrect_password\']) &&
in_array(\'custom_role\', (array) get_user_by(\'login\', $_POST[\'log\'])->roles)){
$errors->errors[\'incorrect_password\'][0] = \'Custom message\';
}
return $errors;
}, 10, 2);
编辑：
这应该适用于WooCommerce登录表单或任何其他实现wp_signon:
add_filter(\'authenticate\', function($user, $username, $password){
if(is_wp_error($user) &&
isset($user->errors[\'incorrect_password\']) &&
in_array(\'custom_role\', (array) get_user_by(\'login\', $username)->roles)){
$user->errors[\'incorrect_password\'][0] = \'Custom message\';
}
return $user;
}, 21, 3);
