Issue with HTML2PDF, not rendering PDF

Asked 4/4, 2012 at 18:43 Answered 5/4, 2012 at 13:34

Solved php html pdf tcpdf html2pdf

For some reason the HTML2PDF/TCPDF is not rendering the PDF... and I have no idea why... :S

render.php (main file)

form.php

(The links will lead you to the code im trying to use, so you can test it, you will only need the HTML2PDF Class)

can somebody tell me why the form isn't rendering??? I'm freaking out!!!

thanx in advance!!

Any particular error you encountered? – Feil 4/4, 2012 at 18:48

the funny thing is that there is no error catch from the class and neither from php or apache. thats the thing that's freaking me out. I also should point that this is the first time I used HTML2PDF or any PDF generation class, so I hope somebody has a clue... – Zolnay 4/4, 2012 at 18:53

The answer was the execution time.

Solved it by using the set_time_limit() function.

Check the webserver logs for any html2pdf-related errors. If you're using apache, command will look like this:

tail -f -n 500 /var/log/apache2/error.log

Updated my answer since if pdf gets rendered but is empty, it's not a permission issue.

BluesRockAddict, have you checked the files, There is no problem with the permissions, when I take out the HTML/form it renders the pdf (empty) – Zolnay 4/4, 2012 at 19:3

$html2pdf->writeHTML($content, isset($_GET['vuehtml'])); - looks like the correct name is WriteHTML (i.e. with capital W). – Neuralgia 4/4, 2012 at 19:11

I changed it but it didnt make any change. :S – Zolnay 4/4, 2012 at 19:20

no, thats freaking strange... no errors of any kind, just wont render. – Zolnay 4/4, 2012 at 19:27

What happens if you do $html2pdf->WriteHTML("<html><body><p>Test</p></body></html>")? Do you get "Test" in pdf or is it still empty? – Neuralgia 4/4, 2012 at 19:34

HTML2PDF class auto generates the html and body tags, i tried small structures and its all ok, the problem is when I try to load "heavy" forms – Zolnay 4/4, 2012 at 19:40

Quick google search indicated that html2pdf doesn't work well with complex html documents, you might want to try using fpdf/mpdf instead. – Neuralgia 4/4, 2012 at 20:4
