Php 在yii2中使用ajax填充或填充所有字段

php jquery mysql ajax yii2

Php 在yii2中使用ajax填充或填充所有字段,php,jquery,mysql,ajax,yii2,Php,Jquery,Mysql,Ajax,Yii2,当我输入Email ID并点击按钮时，我想在yii2中使用ajax填充所有字段，而不是用户名，所有细节都应该从mysql数据库中获取，并使用jquery填充字段。我的代码如下 signup.php <?php $form = ActiveForm::begin([ 'options' => ['name' => 'membershipForm', '

当我输入Email ID并点击按钮时，我想在yii2中使用ajax填充所有字段，而不是用户名，所有细节都应该从mysql数据库中获取，并使用jquery填充字段。我的代码如下

signup.php

                                    'action' => ['']
                        ]);

这是在我的SiteController.php中

 public function actionFormajax1(){
  // return $this->render('formajax');
  $sql ="SELECT email,first_name,last_name FROM member";
  $formajax1 = Member::findBySql($sql)
  -all();
  Yii::$app->response->format = Response::FORMAT_JSON;
  if (Yii::$app->request->isAjax) {
    $data = Yii::$app->request->post();
    // $searchname= explode(":", $data['searchname']);
    // $searchby= explode(":", $data['searchby']);
    $email = $data['email'];
    $first_name= $data['first_name'];
    $first_name= $data['first_name'];
    $responsedata = // your logic;
    \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
    return [
        'responsedata' => $responsedata,
        'formajax1' => $formajax1,
    ];
  }
  }

请让我知道怎么做，因为这对我来说是新的。。多谢各位

    $("#PopupulateData").on("click", function(event){

     // var form = $('form[id="formajax"]');
      event.preventDefault();
      var email = $("#email").val();
      var first_name = $("#first_name").val();
      var last_name = $("#last_name").val();
// console.log("Success");
     // var form = document.getElementById("form-ajax");
     // form.attr('action', '$ajax_info');
     // form.$("#you_button_id").on("submit", form_submit, false);
     //var valNew = bounced.split("|");
            // $('#first_name').value;
            // $('#last_name').value;
            //$('#email').value;
     $.ajax({
         type: "POST", url: "formajax1",
         dataType: 'json',
         data: {
           email : email,
           first_name : first_name,
           last_name : last_name,

         },
         async: true,
         success: function (response) {
            console.log(response);
             if(response != ''){
                 var json_obj = jQuery.parseJSON(JSON.stringify(response));
                 console.log(json_obj);
                 console.log("Success");
                            }
             }

       })

     });

现场控制员是

public function actionFormajax1(){
  $formajax1 = Member::find()
  ->all();
  if (Yii::$app->request->isAjax) {
      $return = [];
      $data = Yii::$app->request->post();
      // print_r($data);exit;

          // $username = $data['username'];
          $email = $data['email'];
          // $password = $data['password'];
          $first_name = $data['first_name'];
          $last_name = $data['last_name'];
          // $dob = $data['dob'];
          // $gender = $data['gender'];
          // $country = $data['country'];
          // $city = $data['city'];
          // $state = $data['state'];
          // $zip = $data['zip'];
          // $phone = $data['phone'];
          // $mobile = $data['mobile'];
          // $organization = $data['organization'];
          // $address = $data['address'];

          // $return['username'] = $username;
          $return['email'] = $email;
          // $return['password'] = $password;
          $return['first_name'] = $first_name;
          $return['last_name'] = $last_name;
          // $return['dob'] = $dob;
          // $return['gender'] = $gender;
          // $return['country'] = $country;
          // $return['city'] = $city;
          // $return['state'] = $state;
          // $return['zip'] = $zip;
          // $return['phone'] = $phone;
          // $return['mobile'] = $mobile;
          // $return['organization'] = $organization;
          // $return['address'] = $address;

      // $session = Yii::$app->session;


      echo json_encode($return);
  }
}

现在的问题是我无法从电子邮件Id获取输入

您不需要手动完成这一切，您只需使用Pjax，它会有所帮助您可以自动执行类似的操作（更新表单字段而无需重新加载

您可以通过以下链接找到Pjax的文档：

NoteController.php：

public function actionCreate()

    $model = new Note();
    if ($model->load(Yii::$app->request->post()) && $model->save())
    {
        return $this->render('edit', [
            'model' => $model

    return $this->render('create', [

在您的情况下，也可以执行类似此示例的操作。

您的错误在哪里？你可以在互联网上找到很多教程，帮助你如何在yii2上进行ajax调用。这些代码不起作用。因为它没有显示任何错误。如果你知道解决办法，那就把我打回去。thanksI需要知道您的代码在哪里中断，例如在控制器中发布一个var_dump（$data）。在js文件中，如果ajax成功，则必须执行以下操作：url try:，success:function（response）{alert（response）；}Uncaught SyntaxError:JSON中位于位置1的意外标记o我认为您试图解析JSON数据两次。
