html - DOMPDF not working -


i trying take html textarea , convert pdf. donwnloaded dompdf https://github.com/dompdf/dompdf , wrote code below. when click submit error: "internal server error". (my webhost doesn't tell me line it's one) (the name of file test2.php)

<?php if (isset($_post['submit'])) { $content = $_post['content']; if (empty($content)){     $error = 'write something'; } else {     include_once( 'dompdf/dompdf_config.inc.php' );     $dompdf = new dompdf();     $dompdf->load_html($content);     $dompdf->render();     $dompdf->stream('example.pdf'); } }   ?> <!doctype html> <head>  </head> <body> <?php if(isset($error)){ echo $error; } ?> <form method="post" action="test2.php"> <textarea name="content" id="content">hello world</textarea><br> <input type="submit" name="submit" value='submit'> </form> </body> </html>

i had similar issue on client's server when using dompdf project.

it's possible not have right level of error reporting configured installation of php.

at top of script place following; error_reporting(e_all);

example:

error_reporting(e_all); if (isset($_post['submit'])) { $content = $_post['content']; if (empty($content)){     $error = 'write something'; } else {     include_once( 'dompdf/dompdf_config.inc.php' );     $dompdf = new dompdf();     $dompdf->load_html($content);     $dompdf->render();     $dompdf->stream('example.pdf'); } }

you should see more detailed message type of error received.

there issues html markup passing $dompdf->load_html($content); method or alternatively might experiencing memory related issues (exceeding memory allowance).

typically these errors report again depending on setup, reporting might limited.
