Yii 1.1: List with multiple checkbox

8 followers

It is a common case coders often come accross. For example the purpose of these checkbox is to mark records to be deleted

First of all lets define a very useful 'polymorphic' form. I am sure you will use it a lot now !

<?php
/**
 * PolymorphicForm.php in 'models' directory
 */
class PolymorphicForm extends CFormModel
{
  private $data = array();
 
  public function __get($key) {
    return (isset($this->data[$key]) ? $this->data[$key] : null);
  }
 
  public function __set($key, $value) {
    $this->data[$key] = $value;
  }
}
?>

Continuing with models, lets define a table 'Example' with fields : keyExample, Field_one, Field_two. You know how to do it don't you ? ...

Then in the controller ExampleAction.php, the action dealing with the list of this table 'Example'

...
// an over simplified 'list' action 
public function actionList ()
{
  $form = new PolymorphicForm;
 
  $this->render("list", array(
    "models" => Example::model()->findAll(),
    "form"   => $form, 
  ));
}
...

Then the view defined in file list.php

<script language="javascript">
  function byebye ()
  {
    // need a confirmation before submiting
    if (confirm('Are you sure ?'))          
      $("#myForm").submit ();
  }
 
  $(document).ready(function(){
    // powerful jquery ! Clicking on the checkbox 'checkAll' change the state of all checkbox  
    $('.checkAll').click(function () {
      $("input[type='checkbox']:not([disabled='disabled'])").attr('checked', this.checked);
    });
  });
</script>
 
<?php echo CHtml::beginForm("index.php?r=Example/delete", "post", array("id"=>"myForm")); ?>
 
<table>
  <tr>
    <th><?php echo "Blabla" ?></th>
    <th><?php echo "Blabla bis"; ?></th>
    <th>
    All <?php echo CHtml::activeCheckBox($form, "checkAll", array ("class" => "checkAll")); ?>
    <button
      type="button"             
      onClick="byebye()"
    >
      Delete
    </button>
    </th>
  </tr>
 
  <?php foreach($models as $n=>$rec): ?>
  <tr>
    <td>
    <?php echo CHtml::encode($rec->Field_one); ?>
    </td>
    <td>
    <?php echo CHtml::encode($rec->Field_two); ?>
    </td>
    <td>
    <?php echo CHtml::activeCheckBox($form, "checkRecord_$rec->keyExample"); ?>
    </td>
  </tr>
  <?php endforeach; ?>
 
</table>
<?php echo CHtml::endForm(); ?>

Finally the trick to deal with these checkboxs in ExampleAction.php

...
/**
* Deletes a range of model
* If deletion is successful, the browser will be redirected to the "list" page.
*/
public function actionDelete()
{
  // I want a post  
  if(Yii::app()->request->isPostRequest)
  {
    // parse $_POST variables
    foreach($_POST["PolymorphicForm"] as $key => $val) {
      // is one a these checkbox ?
      if (strstr ($key, "checkRecord")) {
        // checkbox in state checked ?
        if ($val == 1) {
          // get the key of the record
          $ar = explode ("_", $key);
          // deleting record 
          $model = Example::model()->findByPk ($ar[1])->delete ();
        }
      }
    }
    $this->redirect(array("list"));
  } 
  else
    throw new CHttpException(400,"Invalid request. Please do not repeat this request again.");
}
 
...

The result can be tested, calling http://myHttpServer/myApp?r=Example/list

I hope this will be useful for some of the Yii coders.
