Double action (GET & POST) posted!

Hi Guys,

just trying to solve a double action error within my gallery i'am working on.

i have a module which starts a java-applet for uploading files, the applet calls the module itself with a special querystring during the post in the formaction to activate the uploadhandler-method in the class

after the applet sends the formdata i get the double action error.

this is my querystring as formaction: index.php?a=112&id=2&advalbum_action=imagemanager&advalbum_todo=requestupload&advalbum_album=1&SN50aed810730df=ojs0ujf4ejpajjnhdcm3ba43db4or384qqjvsrikpaue4lj9qud1


thx

I've never heard of this before, but I did find this http://mercstudio-tech.blogspot.co.il/2010/08/double-action-get-post-posted-modx.html

Hello Susan, thanks for your awesome fast reply

yes also found that over google, but i need the "a" parameter to switch to the modules-screen to pass the "get" parameters to the module to activate the uploadhandler.

Maybe you wish to have a look at the module-class to figure out what i mean, there is a method called requestUpload(); in advalbum.module.class.php on line 1021 which is started in the background by the javaupload-applet, the applet opens the module with the querystring "a" parameter in the formaction and passes html-postvars as standard formdata, simply said a second modx instance will be opened but only for uploading

The complete gallery can be downloaded here: http://wiki.012h.de/doku.php?id=en:advalbum:download

Installationinfo is provided here: http://wiki.012h.de/doku.php?id=en:advalbum:how_to_install_advalbum

i'am currently out of ideas how to solve this, a separate php file for uploading is also unsuitable since it need access to alot of other methods in the class like imagescaling and database access etc.

thx

So, noone an idea?

Well i figured out what causes modx to reject uploads from my java-applet (JUpload) within my gallery-module in my case, this may also be possible with other client-side upload solutions like flash etc.

in /manager/index.php around line 190 to 200 you have the following if statement:

// OK, let's retrieve the action directive from the request
if(isset($_GET['a']) && isset($_POST['a'])){
$e->setError(100);
$e->dumpError();
// set $e to a corresponding errorcode
// we know that if an error occurs here, something's wrong,
// so we dump the error, thereby stopping the script.
} else {
$action= (int) $_REQUEST['a'];
}

This statement checks also for POST "a" but i don't have any "a" var in my Postvars when i upload, so currently i'm puzzling around why this if statement will catch.

Solved Lot of thanks for your Help!

It seems that it is not allowed to pass any action parameter over an URL-Querystring, the upload java-applet now posts the "a" parameter via POST to switch to the modules-screen, works in both evolution and revolution.

So long, Daniel
