The radio parameter type provides radio buttons to select different options. If the parameter has a saved value this is selected when the page is first loaded. If not, the default value (if any) is selected.

  • type (mandatory) must be radio.
  • name (mandatory) is the unique name of the parameter.
  • label (mandatory) (translatable) is the descriptive title of the field.
  • default (optional) is the default radio button item value.
  • description (optional) (translatable) is text that will be shown as a tooltip when the user moves the mouse over the drop-down box.

The XML <param> element must include one or more <option> elements which define the individual radio button items. The text between the <option> and </option> tags is shown as the label for the radio button and is a translatable string. The <option> tag takes the following argument:

  • value (mandatory) is the value that will be saved for the parameter if this item is selected.

Tip: Don't forget to close the parameter definition with </param>.

Example XML parameter definition:

<param name="myradiovalue" type="radio" default="0" label="Select an option" description="">
  <option value="0">1</option>
  <option value="1">2</option>
</param>
