I installed mpdf successfully via composer.
Here is my PHP code:
require_once __DIR__ . '/vendor/autoload.php';
$mpdf=new \Mpdf\Mpdf();
$mpdf->WriteHTML("<h1>test</h1>");
$file='abcd.pdf';
$mpdf->output($file,'I');
PDF won't generate. I tried in Chrome and Firefox.
The location of autoload.php is correct.
I tried D, F and S as well, as the second argument for $mpdf->output, none worked.
your code actually works, please double check your php version
and note that mpdf is compatible only with PHP ≥ 5.6.0 and < 7.4.0.
require_once __DIR__ . '/vendor/autoload.php';
$mpdf=new \Mpdf\Mpdf();
$mpdf->WriteHTML("<h1>test</h1>");
$file='abcd.pdf';
$mpdf->OutputHttpDownload($file);
You can use the OutputHttpDownload method passing the name of your file and it will work!
Use this create a temporary directory and then do this
$upload_dir = wp_upload_dir();
$custom_temp_dir = $upload_dir['basedir'] . '/mpdf_temp/';
if (!file_exists($custom_temp_dir)) {
mkdir($custom_temp_dir, 0755, true);
}
$mpdf = new \Mpdf\Mpdf(['tempDir' => $custom_temp_dir]);
$mpdf->WriteHTML("<h1>test</h1>");
$file='abcd.pdf';
$mpdf->output($file,'F');
