Hidden form field type

From Joomla! Documentation

The hidden form field type provides a hidden field for saving a field whose value cannot be altered directly by a user in the Administrator (it can be altered in code or by editing the params.ini file). If the parameter has a saved value this is entered in the text box. If not, the default value (if any) is entered. As the field is hidden there is no visible field in the Administrator.

  • type (mandatory) must be hidden.
  • name (mandatory) is the unique name of the field.
  • default (mandatory) is the data which needs to be collected.
  • class (optional) is a CSS class name for the HTML form field. If omitted this will default to 'text_area'.

Example XML field definition:

<field name="mysecretvariable" type="hidden" default="" />
