在按钮上调用控制器动作的问题单击

Question

I'm having a problem calling an action in a controller upon button click. So the controller is generated by Gii. All of its actions are the default ones generated by Gii, except for the actionCreate().

Here is the relevant code ::

class ProductsController extends Controller {
 public function actionCreate() {
        $model = new Products;



      if (isset($_POST['params'])) {
        //  $model->attributes = $_POST['Products'];
        //if ($model->save())
         //   $this->redirect(array('view', 'id' => $model->id));
         echo 'Yes Working';
    }

    $this->render('create', array(
        'model' => $model,
    ));
}

As its clear from the above code snippet this action is calling the view named create.php. Here is create.php::

<div class="page">
<div class="container">
    <div class="row">
    <h2>Create Products</h2>

    <?php echo $this->renderPartial('_form', array('model' => $model)); ?>
    </div>
</div>

And here is the partially rendered form.

<?php
$form = $this->beginWidget('bootstrap.widgets.TbActiveForm', array(
    'id' => 'products-form',
    'action' => Yii::app()->createUrl('products/create'),
    'enableAjaxValidation' => false,
        ));
?>

<div class="form-actions">
    <?php
    echo CHtml::submitButton('Create', array(
        'submit' => 'EasyAesthetics/index.php/products/create',
        'params' => '1'
    ));
    ?>
</div>

<?php $this->endWidget(); ?>

Now what I want is that upon clicking the button 'Create', it would call the actionCreate() method in the ProductsController. Right now the button is working and I'm being redirected to /demoProject/index.php/products/create, but the echo 'Yes Working' is not displaying.

Can anyone please show me how to achieve this. How can i invoke the create action again with just a button and just a 1 in the $_POST array.

I need to do this so that on clicking create the actionCreate() method will call the relevant components to create the necessary products.

Take a look at the code generated by your form. When you have model called "Hello" with a field called "world", your form field will be

<input type="text" name="Hello[world]">

Try to change your action in this way:

class ProductsController extends Controller {
    public function actionCreate() {
        $model = new Products;
        if (isset($_POST['Products'])) {
            echo 'Yes Working';
        }
        $this->render('create', array(
            'model' => $model,
        ));
    }
}

Pay particular attention to these two lines:

        $model = new Products;
        if (isset($_POST['Products'])) {

Fields will takes the same name of model. In case of more models:

<input type="text" name="Model1[field1]">
<input type="text" name="Model1[field2]">
<input type="text" name="Model21[field2]">
<input type="text" name="Model2[field2]">

and so on ...
