model->save() Not Working In Yii2

Question

Previously, I was not using $model->save() function for inserting or updating any data. I was simply using createCommand() to execute query and

Answer 1

Check model saving error like this :

if ($model->save()) {

} else {
  echo "MODEL NOT SAVED";
  print_r($model->getAttributes());
  print_r($model->getErrors());
  exit;
}

Answer 2

And there maybe another reason of not saving model - you have property of your Users class and before saving from form its reset to NULL.

So, if you set $model->saveAttributes('favorite_book'=>$model->favorite_book), but at that time you declared in class Users public $favorite_book - you will get this field empty in DB.

Answer 3

As @scaisEdge suggest, try removing all table related field in your Users class

class Users extends ActiveRecord implements IdentityInterface 
{
  /* removed because this properties is related in a table's field 
  public $first_name;
  public $last_name;
  public $email;
  public $password;
  public $user_type;
  public $company_name;
  public $status;
  public $auth_key;
  public $confirmed_at;
  public $registration_ip;
  public $verify_code;
  public $created_at;
  public $updated_at;
  public $user_type;
  public $company_name;
  public $status;
  public $auth_key;
  public $confirmed_at;
  public $registration_ip;
  public $verify_code;
  public $created_at;
  public $updated_at;
  */

  // this is properties that not related to users table
  public $rememberMe;
  public $confirm_password;
  public $_user = false;

  public static function tableName() {
    return 'users';
  }

 /* ........... */

}

Answer 4

The other solution mentioned $model->save(false);. That is just a temporary workaround, and you should still find the actual reason why the save functionality is not working.

Here are additional steps to help diagnose the actual issue:

1. check that _form input field has the proper name, and
2. check that if you have added any dropdown functionality, then check whether it's working properly or not

Answer 5

I guess $model->load() returns false, call $model->errors to see model's error.

$model->load();
$model->validate();
var_dump($model->errors);

Answer 6

You are doing all staff correct. I think u must add one line for confirm password validation

if(!$CheckExistingUser) {    
$auth_key = $model->getConfirmationLink();
        $password = md5($post['password']);
        $registration_ip = Yii::$app->getRequest()->getUserIP();
        $created_at = date('Y-m-d h:i:s');

        $model->auth_key = $auth_key;
        $model->password = $password;
        $model->confirm_password= md5($post["confirm_password"]);  /// add  this line
        $model->registration_ip = $registration_ip;
        $model->created_at = $created_at;

And Also after this condition check model attributes and error like this :

if($model->save()) {
          print_r("asd");
        }else{
var_dump($model);exit;}
