Handling of form data

[vinaysaini]

I was wondering how controller handles the from data sent by any of the controller.

For ex. 

On prestashop back office if you go to Preferences->Maintenance page.

You have option of enabling and disabling shop(For maintenance mode). If you click on save button, The data sent to the controller is

Content-Disposition: form-data; name="multishopOverrideOption[PS_SHOP_ENABLE]" 1

Content-Disposition: form-data; name="PS_SHOP_ENABLE" 1 ---

Content-Disposition: form-data; name="submitOptionsconfiguration" 1

 

I want to know which files is handling this data? Any help will be appreciated.
