not sure if this problem is CMSMS related at all but i'm at a loss.

i have a form that is submitted to a very basic page (template only contains {content}). the content only contains a plugin i wrote. previously, the form action was kept external, but once i realised how easy it is to turn scripts into plugins, i did so. all works well.

now i tried to include mPDF in that plugin. which also works well.

mPDF in its simplest form would look like this:

Code: Select all

  $html = '<h1>Name: ' . $_POST['firstname'] .'</h1>';
  require('mpdf/mpdf.php'); 
  $mpdf=new mPDF();
  $mpdf->WriteHTML($html);
  $mpdf->Output();
  exit();

all this works well, except that the pdf would only print "Name: "

when i echo $html instead, it prints correctly: "Name: rotezecke". print_r($_POST) also shows what is expected.

is there something in CMSMS preventing $_POST to be accessed by external classes, and if so, how can I work around this?

$_POST is a server side var and there's nothing inside CMSMS which limit the access to server side vars.

Include mPDF at the first line of your script so it will know the var $html too

.

Maybe a look to the sources of this project

http://dev.cmsmadesimple.org/projects/pdf

could be helpful too.

i turned my action script from a CMSMS plugin to an external file, updated a few variables, and Bob's your uncle.

could the pretty URL redirects empty the post array? but if that's the case, how come they arrive at all? anyway, workaround found, but not sure why this happens.

chandra is correct $_POST is a server provided variable. and nothing inside of CMSMS touches it. I have tested this numerous times.

So any difficulties you may be having are entirely related to your scripts.

If the rewrite_url is initiating a browser redirect then I think the post request is turned into a get request without all parameters.

You could see that happen with a web inspector.

The default .htaccess that comes with cmsms has some conditions that do prevent post requests from being redirected. This could the/one reason.
