Error while creating form

Question

I'm trying to create a basic form by referring the guide from tutorial

This is my version of form

class UsersForm extends BaseUsersForm
{
  public function configure()
  {
      $this->useFields(["name,email"]);

      $this->setWidgetSchema("email") = new sfWidgetFormInputText();
      $this->setWidgetSchema("name") = new sfWidgetFormInputText();

      $this->validatorSchema["email"] = new sfValidatorEmail();
      $this->validatorSchema["name"] =new sfValidatorString(["max_length" => "30"]);

      $this->widgetSchema->setLabels([

          "email" => "Email Address",
          "name" => "User name"

      ]);

  }
}

And I got this error

Fatal error: Can't use method return value in write context

Please tell me if I did wrong any part of the code.

Symfony 1.4 is not maintained anymore, you should not waste your time learning it, learn Symfony2 instead — goto

There are several errors in your code, beginning with:

$this->useFields(["name,email"]);

where you probably wanted to write:

$this->useFields(["name", "email"]);

The fatal error you're getting is because of this snippet (you're trying to assign a value to function return value):

$this->setWidgetSchema("email") = new sfWidgetFormInputText();
$this->setWidgetSchema("name") = new sfWidgetFormInputText();

a better version would be:

$arWidgets = [
   "email" => new sfWidgetFormInputText(),
   "name" => new sfWidgetFormInputText(),
];

$arValidators = [
   "email" => new sfValidatorEmail(),
   "name" => new sfValidatorString(["max_length" => "30"]),
];

$this->setWidgets($arWidgets);
$this->setValidators($arValidators);

After applying these changes your problem should be solved.
