我在将正确的值传递给视图中的网格小部件时遇到问题。数据是使用 ajax 从 jquery 传递的。
这是代码::
$('#find-product').click(function(e) {
e.preventDefault();
alert($('#find-product').data("url"));
/*
* Make the ajax call to send the selected option to the controller for processing
* URL : $('#find-product').data("url") , the path of the controller's action
* Dropdown : the obejct that is passed to the controller
*
* Dropdown.category : the category selected
* Dropdown.price : the price range selected
*
*
*/
$.ajax({
url: $('#find-product').data("url"),
data: {
Dropdown: {
category: $('#supp-category').find(":selected").text(),
price: $('#supp-price').find(":selected").text()
}
},
type: "POST",
error: function(xhr, tStatus, e) {
if (!xhr) {
alert(" We have an error ");
alert(tStatus + " " + e.message);
} else {
alert("else: " + e.message); // the great unknown
}
},
success: function(resp) {
document.location.href = $('#find-product').data("url");
}
})
});
所以我想将名为 Dropdown 的对象发送到控制器操作。在这种情况下，它的 /products/dropdown。
在 actionDropdown() 我试图形成一个 CDbCriteria 并将其传递给 CActiveDataProvider 以便我可以使用它来呈现网格。
这是 ProductsController 中 actionDropdown 的代码 ::
public function actionDropdown() {
$criteria = new CDbCriteria;
$criteria->compare('category', $_POST['Dropdown']['category'], true);
$dataProvider = new CActiveDataProvider('Products', array(
'criteria' => $criteria,
));
$this->render('selectproducts', array(
'dataProvider' => $dataProvider,
));
}
这是视图，称为 selectproducts。
<div class="row">
<?php
$this->widget('bootstrap.widgets.TbGridView', array(
'id' => 'products-grid',
'dataProvider' => $dataProvider,
'filter' => $dataProvider,
'columns' => array(
'id',
'name',
'category',
'brand',
'weight_unit',
'price_unit',
'flavors',
'providers',
),
));
?>
</div>
现在这给了我一个 CException 错误。这是错误堆栈跟踪::

我一生都无法弄清楚导致此错误的原因。请提供任何帮助，任何能让我朝着正确方向前进的提示。
