I have created a admin page with grid for listing the content from a custom table. The data is displaying correctly. Now i need to add edit functionality.
I have added the code for showing the edit page in Grid.php
<?php
class Buildnext_Producteditrequest_Block_Adminhtml_Producteditrequest_Grid
extends Mage_Adminhtml_Block_Widget_Grid
{
public function __construct()
{
parent::__construct();
$this->setId('producteditrequestGrid');
// This is the primary key of the database
$this->setDefaultSort('pdt_edit_id');
$this->setDefaultDir('ASC');
$this->setSaveParametersInSession(true);
}
protected function _prepareCollection()
{
$collection = Mage::getModel('producteditrequest/producteditrequest')
->getCollection()-> addCustomerNameToSelect();
//echo $collection->getSelect();
$this->setCollection($collection);
return parent::_prepareCollection();
}
protected function _prepareColumns()
{
$this->addColumn('pdt_edit_id', array(
'header' => Mage::helper('producteditrequest')->__('ID'),
'align' =>'right',
'width' => '50px',
'index' => 'pdt_edit_id',
));
$this->addColumn('product_code', array(
'header' => Mage::helper('producteditrequest')->__('Product Code'),
'align' =>'right',
'width' => '50px',
'index' => 'product_code',
));
$this->addColumn('fullname', array(
'header' => Mage::helper('producteditrequest')->__('Seller'),
'align' =>'left',
'index' => 'seller_id',
'format' => '$fullname'
));
$this->addColumn('action',
array(
'header' => Mage::helper('producteditrequest')->__('Action'),
'width' => '50px',
'type' => 'action',
'getter' => 'getId',
'actions' => array(
array(
'caption' => Mage::helper('producteditrequest')->__('View'),
'url' => array(
'base'=>'*/*/edit',
),
'field' => 'pdt_edit_id'
)
),
'filter' => false,
'sortable' => false,
'index' => 'pdt_edit_id',
));
return parent::_prepareColumns();
}
public function getRowUrl($row)
{
return $this->getUrl('*/*/edit', array('id' => $row->getId()));
}
}
When i click on a row to edit. I'm getting following error.

Is there any additional configuration file that i need to add. Also is there a good tutorial for creating edit page.
Best Answer
The error you are getting has nothing todo with the code you showed.
As it says, a layout xml update cannot be parsed.
In your extension, you would have defined a layout update xml file. Your problem is with that file and malformed xml.
Don't literally expect a missing < (but could be) You can, for example, have a missing closing " somewhere.
Good luck.
