Question

I have set the following Code within WebController.php

/**
* Export order grid to CSV format
*/
public function exportCsvAction()
{
    $fileName = sprintf('stores-%s.csv', date('Ymd'));
    $grid = $this->getLayout()->createBlock('adminhtml/web_web_grid');
    $this->_prepareDownloadResponse($fileName, $grid->getCsvFile());
}

I don’t know what is the problem that causing CSV not to be exported.

Following error is showing –

Fatal error: Call to a member function getCsvFile() on a non-object in
/var/www/projects/tmp/storelocator/app/code/local/Company/Web/controllers/Adminhtml/WebController.php
on line 0

Please help!
Thanks in Advance.

Answer 1

This line :

$grid = $this->getLayout()->createBlock('adminhtml/web_web_grid');

returns null. The error tells you it clearly :

Fatal error: Call to a member function getCsvFile() on a non-object

Are you sure this ‘adminhtml/web_web_grid’ relates to a block ?

Do you have a folder/file Web/Web/Grid.php in the Block folder of the adminhtml module ?

For example, if you didn’t overload the Mage_Adminhtml module, you should have a class named Mage_Adminhtml_Block_Web_Web_Grid in the folder app/code/local/Mage/Adminhtml/Block/Web/Web/Grid.php that’s what the createBlock('adminhtml/web_web_grid') is searching for
