Symfony 1.4表单复选框数组到字符串转换

Posted 2021-04-02

在Symfony 1.4应用程序中创建复选框时出现以下错误。复选框已呈现，但“阵列到字符串会话”错误。

以下是我的代码。

形成

$this->setWidget('emails', new sfWidgetFormChoice([
      'label'    => 'Emails',
      'expanded' => true,
      'multiple' => true,
      'choices'  => array('test', 'test2'),
    ]));

给予

<div class="container emails">
    <fieldset>
      <legend>
        <?php echo $form['emails']->renderLabel(); ?>
      </legend>
        <?php echo $form['emails']->render(); ?>
        <?php echo $form['emails']->renderError(); ?>
    </fieldset>
  </div>

错误

Notice: Array to string conversion in /var/www/html/symfony/1_4_1/lib/widget/sfWidgetFormSelectCheckbox.class.php on line 103

Notice: Array to string conversion in /var/www/html/symfony/1_4_1/lib/widget/sfWidgetFormSelectCheckbox.class.php on line 10

我的Php版本是5.5.8 Symfony版本1.4.19

我知道最好的方法是将应用程序移动到最新的symfony版本，但是这个应用程序太大而无法重写。

任何人都知道如何解决它？

//编辑

我注意到如果我改变代码

$arr = [];
    array_push($arr, 'test');
    array_push($arr, 'test2');


    $this->setWidget('emails', new sfWidgetFormSelectCheckbox([
      'label'    => __('Adresy email'),
      'choices'  =>$arr,
    ]));

它返回任何错误，但如果我再向数组添加一个值，则会再次显示错误。

全班代码

class EmailFooterGeneratorForm extends BaseForm
{
  /**
  * configure...
  *
  * @param mixed $data
  */
  public function configure()
  {
    sfContext::getInstance()->getConfiguration()->loadHelpers('I18N');

    $this->setWidget('regards', new sfWidgetFormInputText([

    $this->validatorSchema['phones'] = new sfValidatorString(['required' => false]);
    $this->validatorSchema['certyfications'] = new sfValidatorString(['required' => false]);
  }

  private function buildEmployment($employment)

    $arr = [];
    foreach ($employment as $key) {
      $str =

      $arr[] = $str;
    }

    return $arr;
  }
}

答案

这有点晚了，但是由于我遇到了这个问题并且其他人可能需要它，我发现问题是我使用sfWidgetFormChoice设置为多个，但我没有告诉验证器。

解决方案就是将选项传递给它。

最终有类似的东西

$this->validatorSchema['choices_name'] = new sfValidatorChoice([
    'required' => false,
    'multiple' => true,
    'choices'  => $choices
]);

我在Form类中使用它，这就是为什么你看到$this->validatorSchema，如果你在其他任何地方使用它，就像在OP的情况下，只需在选项数组中添加'multiple' => true作为选项。
