The kHTTPQuery class is used in K4 for pre-proccessing and then to safely use the following types of data:

As far as user data, we're referring to the content of the following built in PHP arrays:

  1. $_COOKIE - cookies, that are stored on the user's computer
  2. $_GET - parameters passed in the address bar of the internet browser
  3. $_POST - values of the fields in a form
  4. $_FILES - files uploaded through a form
Image:Tipbox Icon.gif Arrays are listed in the order in which they were added to the variables register through this class.

Also available are arrays $_ENV and $_SERVER, but right now they're not used in K4.

Data Passed by the User (From the Browser)

For user data it's possible to include all variables received from built-in PHP arrays. In the image above, it would be the variables with the following names:

  • From array $_COOKIE 
TreeExpandStatus, cookies_on, catalog_active_prefix, adm_sid, __qca
  • From array $_GET 
env

User Variables defined by the system 

module, section

Parsed Environment Variable

In this example, all the variables that aren't covered, are received as a result of processing the Environment Variable. It's easy to determine these variable because their names will contain an underscorce ("_").
