I already found many questions here in SO about the theme, but any of them helps me with a specific problem.
I need to send a ajax request to PHP and then download a PDF file.
This is my Javascript
$('body').on("click",'.download-file', function(e) {
e.stopPropagation();
var id = $(this).attr('data-id');
$.ajax({
url: 'app/myPage/download',// The framework will redirect it to index.php and then to myPage.class and method dowload
data: id,
type: 'POST',
success: function (return) {
console.log(return);
},
error: function(jqXHR, textStatus, errorThrown) {
console.log("Error... " + textStatus + " " + errorThrown);
}
});
});
Here is my PHP file:
class myPage{
public function download()
{
$id = $_POST['id'];
$filePath = $this->methodToGetFile($id);
$name = end(explode('/',$filePath));
$fp = fopen($filePath, 'rb');
header("Cache-Control: ");
header("Pragma: ");
header("Content-Type: application/octet-stream");
header("Content-Length: " . filesize($filePath));
header("Content-Disposition: attachment; filename='".$name."';");
header("Content-Transfer-Encoding: binary\n");
fpassthru($fp);
exit;
}
}
With this approach, I have the PDF "printed" in the console like
%PDF-1.5%����1 0 obj<</Type/Catalog/Pages 2 0 R/Lang(pt-BR) /StructTreeRoot 8 0 R/MarkInfo<</Marked true>>>> ....
So, I'd like to know what should I do to open this file and download it.
In the linked questions I see something about window.location, but I don't know how can I use it.
I've already tried change the PHP headers to try force the download, but no success with it. In these cases I just receive null in the javascript nothing happens. Here are the modified headers:
header('Content-Type: application/pdf');//tried with this option
//header('Content-Type: application/octet-stream');// also tried with this other option
header('Content-Disposition: attachment; filename=' . $name);
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($filePath));
Are there some good approach to do this?
