开始：
public function executeRegistrantsToCsv(){
$id = $this->getRequestParameter('id');
$c = new Criteria();
$c->add(RegistrantPeer::EVENT_ID, $id);
$c->add(RegistrantPeer::STATUS, 1);
$this->aObjReg = RegistrantPeer::doSelect($c);
$this->forward404Unless($this->aObjReg);
$this->setlayout('csv');
$this->getResponse()->clearHttpHeaders();
$this->getResponse()->setHttpHeader('Content-Type', 'application/vnd.ms-excel');
$this->getResponse()->setHttpHeader('Content-Disposition', 'attachment; filename=registrants_report_event_' . $id . '.csv');
}
在模板registrantsToCsvSuccess.php：
Title,Name,Email,Phone,Organisation,State,City,Country,Login Date,IpAddress
<? foreach($aObjReg as $r): ?>
<?= $r->getTitle() ?>,<?= $r->getName() ?>,<?= $r->getEmail() ?>,<?= $r->getPhone() ?>,<?= $r->getOrganisation() ?>,<?= $r->getState() ?>,<?= $r->getCity() ?>,<?= $r->getCountry() ?>,<?= $r->getLoginDate() ?>,<?= $r->getIpAddress() ?>,
<? endforeach ?>
in the templates/csv.php:
<?php echo $sf_data->getRaw('sf_content') ?>
