I am working with mPDF, I can't handle how to display php variable and generate&download PDF file. Example :
$a = '<head><body>Example</body></head>';
echo $a;
$mpdf = new mPDF();
$mpdf->WriteHTML('<head><body>Example</body></head>');
$mpdf->Output('filename.pdf', 'D');
This code only downloading pdf generated from ->WriteHTML but not displaying code above. I would display code and download pdf. Thx for tips.
You can't push a download and have it preceeded by HTML in one response.
You can work around this by outputting the HTML and have it include an IFRAME which has a src attribute of the url with the actual download.
dl_html.php:
<?php
$a = '<head><body>Example<iframe style="display:none;" src="dl_pdf.php"></iframe></body></head>';
echo $a;
dl_pdf.php:
<?php
include('mpdf.php');//or similar
$mpdf = new mPDF();
$mpdf->WriteHTML('<head><body>Example</body></head>');
$mpdf->Output('filename.pdf', 'D');
