Validate form and request values

This tool gives you the ability to inspect forms and request values. If you highlight the tool, you will see a list of the internal system parameters in the right-hand area. A filter can be set above the table. Simply enter the search term into the edit field. The filter can be removed by clicking Remove filter. If you deactivate the Show system parameters setting, only the parameters will be shown that you have defined yourself. Select Edit from the context menu if you wish to edit a parameter. With the context menu item Add, your own parameters can be defined for the check.
