Why _GET not works on production server?

[irina_b.]

Hi, I have wrote module that correctly works on local server (PS v 1.6.1.9). But when I upload this module to the server with working-site (PS v 1.6.1.5), I get incorrect data from controller. In this module Ajax sent json to controller.

Controller-code:

 

$json = json_decode($_GET["Data"]);

 

$subject = "=?utf-8?B?" . base64_encode("Subject") . "?=";

$message = "Name: '".$json->name."'\nPhone: '".$json->phone."'.";

 

mail('[email protected]', $subject, $message, "Content-type: text/plain; charset=UTF-8\r\n");

 

echo json_encode('This is valid json.');

 

Local server sends correct data, but production server sends "Name ''\nPhone ''.". Can you help me?

 

And one question: after uploading my module to shop I can't enter into section "modules and services". Production server says: 

 [PrestaShop] Fatal error in module file :/var/www/a20160066/data/www/sandaly.com.ua/classes/helper/Helper.php:

Call to a member function createTemplate() on a non-object

Local server:

Fatal error: Call to a member function assign() on a non-object in D:\Web\OpenServer\domains\prestashop\classes\controller\Controller.php on line 624

[PrestaShop] Fatal error in module file :\Web\OpenServer\domains\prestashop\classes\controller\Controller.php:
Call to a member function assign() on a non-object

How to сorrect this mistake?

how exactly are you sending JSON using GET?  The correct way to obtain data from GET or POST is to use Tools::getValue('Data')

This problem has been solved. It was in the different versions of php servers. But problem of accessing to section "modules and services" is actual. I mistakenly added a module without views directory. What should I do to fix this?

[bellini13]

can you elaborate on what you are asking?

In admin panel I connected the module to site. This module was without directory "view". Now I do not have access to section "modules and services" in admin panel. Production server says: 

 [PrestaShop] Fatal error in module file :/var/www/[any_data]/data/www/[my_site]/classes/helper/Helper.php:

Call to a member function createTemplate() on a non-object

Local server:

Fatal error: Call to a member function assign() on a non-object in D:\Web\OpenServer\domains\prestashop\classes\controller\Controller.php on line 624

[PrestaShop] Fatal error in module file \Web\OpenServer\domains\prestashop\classes\controller\Controller.php:
Call to a member function assign() on a non-object

 

This can be corrected by adding a folder 'view' with a template in the site architecture? If it possible, how?

access your ftp server and delete the module, or fix it by adding the missing folders/files

I can't find a place where I must to add the missing files
