Cant export to excel 2010 student edition via Zend Framework

I'm trying to export data to ms excel, I have Office 2010 student edition for my application by following Pablo Viquez's post http://www.pabloviquez.com/2009/08/export-excel-spreadsheets-using-zend-framework/.

However I can't get it working the following happens

1.On entering reports/report/todaysappointmentsreport/format/excel into the address bar the workbook attempts to save as excel.xls

2.When I open the file Excel gives me the following warning: The file you are trying to open 'excel.xls', is in a different format than specified by the file extension verify the file is not corrupt and is from a trusted source before opening the file.

1. On opening the file all that is shown is the code in my todaysappointmentsreport.export.phtml file

Can anyone tell me where I'm going wrong, as I need to get this working.

I can verify that the query works and the data appears in my todaysappointmentsreport.phtml file on screen. I can also verify that the component is installed in pear along with the OLE component that it is dependent on.

My Controller code

class Reports_ReportController extends Zend_Controller_Action 
 { 
  public function init() 
  { 

       // Excel format context 
            $excelConfig = 
            array('excel' => array 
                                            ('suffix'  => 'excel', 
                                                    'headers' => array( 
                                                                                    'Content-type' => 'application/vnd.ms-excel')), 
            ); 

       //initalise context switch 
       $contextSwitch = $this->_helper->contextSwitch(); 

       // Add the new context 
            $contextSwitch->setContexts($excelConfig); 



            // Set the new context to the reports action 
            $contextSwitch->addActionContext('todaysappointmentsreport', 'excel'); 

            $contextSwitch->initContext(); 

} 

 // action to redirect user straight to login page 
 public function preDispatch() 
 { 
   // set admin layout 
  // check if user is authenticated 
  // if not, redirect to login page 
  $url = $this->getRequest()->getRequestUri();           
  if (!Zend_Auth::getInstance()->hasIdentity()) { 
  $session = new Zend_Session_Namespace('petmanager.auth'); 
  $session->requestURL = $url; 
  $this->_redirect('/login'); 
 } 
    } 

 // report to print todays appointments 
 public function todaysappointmentsreportAction() 
 { 
     $t=date('y-m-d'); 
            $q = Doctrine_Query::create()   
                    ->from('PetManager_Model_Groomappointments g')

                    ->where('g.gapmtStatus = 1 AND g.gapmtDate = ?',$t) 
                    ->orderBy('g.gapmtSTime,g.gapmtSTime,u.name'); 
                     $result = $q->fetchArray(); 
                     if (count($result) >= 1) { 
                     $this -> view -> records = $result;             
                     } 

}   

My todaysappointmentsreport.excel.phtml code as I said this is what appears in the excel file when I open it.

I'm working on a similar example for my own project so if I discover a resolution I'll update this thread with any results.

There's a helpful article on the contextSwitch view helper here (maltblue) which explains the helper in more depth.

contextswitch view helper

I managed to export to csv ok in the end by putting the headers in the controller action directly as follows.

in my action...

//create the csv file header and filename based on the action name
    $actionName = $this->getRequest()->getActionName();
    new Admin_Model_Resource_csvFileHeader( $actionName );

rest of code here to get the data to pass to the view file...

the admin model resource is as follows so it can be used by any controller acton...

class Admin_Model_Resource_csvFileHeader

{

private $_csvFileNameFromAction = null;

/**
 * Create the first part of the csv file name from the action name
 * @param <string> $actionName - name of the controller action for the report
 */
public function __construct( $actionName )
{
    $this->_csvFileNameFromAction = $actionName;
    $this->generateCsvHeader();
}

/**
 * Method is called direct from the constructor
 * to centralise and make consistent the csv file header
 * so it maximises code re-use
 * @return null - just generate the csv header
 */
public function generateCsvHeader()
{
    $dateSuffix = date('d-m-Y', time());
    $csvFileName = $this->_csvFileNameFromAction.'_'.$dateSuffix;

    header('Content-Type: text/x-csv; name="'.$csvFileName.'.csv"');
    header('Content-Disposition: inline; filename="'.$csvFileName.'.csv"');
    header('Pragma: public');
    header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT');
    header('Cache-Control: no-store, no-cache, must-revalidate');
    header('Cache-Control: pre-check=0, post-check=0, max-age=0');
    header('Content-Transfer-Encoding: none');
}

}
