我的电子邮件表单已经过验证。如果用户已注册，则会显示警报并重置具有空值的表单。我需要警报消息以及数据应保留在表单中。提前致谢。 https://plnkr.co/edit/WhdRmJmLs69yaf6Q2uYI?p=preview

add_filter( 'wpcf7_validate_text*', 'validate_pan_card', 20, 2 );
function validate_pan_card( $result, $tag ) {
  $tag = new WPCF7_FormTag( $tag );
  if ( 'your-pancard' == $tag->name ) {
      $your_pan = isset( $_POST['your-pancard'] ) ? trim( $_POST['your-pancard'] ) : '';
      if ( 1 !== preg_match ( "/[A-Z]{3}([CHFATBLJGP])[0-9]{4}[A-Z]/ig" ,  $your_pan) ){
          $result->invalidate( $tag, "PAN Card number is invalid" );
      }
  }
  return $result;
}

不知道你的问题到底是什么，但这就是我在角度1.x中解决自定义电子邮件验证检查的方法。

<强> HTML

<form ng-submit="submit()">
    <input type="email" class="form-control" id="email" name="email" placeholder="email" ng-model="formModel.email" />
    <span ng-show="formModel.$submitted && formModel.teamName.$error.exists">Email already exists</span>
</form>

Js：（在您的角度控制器中）“EmailService”将是您选择的http服务，用于检查您的后端是否存在电子邮件：

myApp.controller('mainController', function($scope, EmailService) {


    $scope.submit = function() {

        $scope.formModel.email.$setValidity("exists", true);
        EmailService.emailExist($scope.formModel.email,  { // check if email exists
            success: function(exists) {

                $scope.$apply(function(){
                    $scope.formModel.email.$setValidity("exists", !exists); // set validation flag
                });

                if($scope.formModel.$valid) {
                    // submit if valid
                }
            }
        }
    }
}

祝你好运！
