You don't have to use jquery or views to do this. I use this handy little
function a lot. I usually put it in a Component but there is no need
unless you need it elsewhere
public function array_to_csv_download($array, $filename = "export.csv",
$delimiter=",") {
// open raw memory as file so no temp files needed, you might run out
of memory though
$f = fopen('php://memory', 'w');
// loop over the input array
foreach ($array as $line) {
// generate csv lines from the inner arrays
fputcsv($f, $line, $delimiter);
}
// rewrind the "file" with the csv lines
fseek($f, 0);
// tell the browser it's going to be a csv file
header('Content-Type: application/csv');
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
// tell the browser we want to save it instead of displaying it
header('Content-Disposition: attachement; filename="'.$filename.'"');
// make php send the generated csv lines to the browser
fpassthru($f);
}
In your controller do
public function export(){
$this->layout = false;
$this->autoRender = false;
$this->loadModel('CadastroMailing');
$conditions = array('OR'=>array('cadastro_mailing_tipo_id'=>$dados));
$result = $this->CadastroMailing->find('all',array(
'conditions'=>$conditions , 'order'=>array('nome ASC')));
$this->array_to_csv_download($result, 'your_filename', $delimiter=",");
}
and that's it, it will generate a csv automatically when you click a link
to that page.
