Hi everybody, I need your help in filtering a dropdown with Ajax in codeigniter. I got a dropdown in my view which lists all product types from database. There's another dropdown which should get all attributes on the base of the product that user will choose accordingly. This is my code for controller:
function getattributetype($type)
{
$data=array();
$this->load->model('Producttypemastermodel');
header('Content-Type: application/x-json; charset=utf-8');
echo(json_encode($this->Producttypemastermodel->get_attributetype($type)));
$data['row2']=$this->Producttypemastermodel->get_attributetype($type);
$this->template->write_view('content','admin/productattr_add',$data);
$this->template->render();
}
This is the code for model:
function get_attributetype($type)
{
$query = $this->db->query("select attr_set from product_type_master where id =".$type);
$row_attr = $query->result_array();
$code = $row_attr[0]['attr_set'];
$query = $this->db->query("select * from attribute_master where id IN( ".$code.")");
$row_attr = $query->result_array();
$row2 = array();
foreach ($row_attr as $product)
{
$row2[$product['id']] = $product['title'];
}
return $row2;
//print_r($row_attr);
//echo "x";die;
}
This is the code for view:
<table border="0">
<tr>
<td> Product Type: </td>
<td>
<?php
echo form_open('admin/product/getproducttype');
$options=$row1;
echo form_dropdown('product_type', $options, '', "id=type");
?>
</td>
</tr>
<tr>
<td> Product Attribute Type: </td>
<td> <?php
echo form_open('product_attribute/getattributetype');
//$opt=$row2;
echo form_dropdown('product_attr',$row2,'',"id=prod_attr");?> </td>
</tr>
The thing's I can see the data coming in Ajax Request in console in firebug whenever i select a product in first dropdown. One More thing it shows me an error like this:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: row2
Filename: admin/productattr_add.php This is the view file in admin folder

A PHP Error was encountered
