Arguments:

Name	Description
$title	Title of the field
$name	Name of the field
$options	The options used for the field
$validator	This can either be the name of your own validation function or the constant name of a predefined validator function. For more information about validators see Validators. It is also possible to use a method as a validation function. In this case you should pass an array where the first item is the object and the second item the name of the method.
$useArrayKeyAsValue	Should the key of the array be used as the value for the field? If not (false) the array value is used. The default option for this can be set in the config file (See FH_DEFUALT_USEARRAYKEY).
$extra	This can be extra information which will be included in the fields html tag. You can add for example some CSS or javascript.
$mask	With this argument you can position the field(s). In the given mask a the placeholder %field% will be replaced with the field. When the mask is full and there are still fields, the mask will be repeated. This works the same as SetMask. When no mask is given the mask will be used which is set in the config file in the var FH_DEFAULT_GLUE_MASK.

<?php // the options for the radiobutton $gender = array(   "m" => "Male",   "f" => "Female" ); // include the class include('FH3/class.FormHandler.php'); // create new formhandler object $form = new FormHandler(); // make the radiobutton $form -> radioButton("Gender", "gender", $gender); // button beneath it $form -> submitButton("Save"); // set the 'commit after form' function $form -> onCorrect("doRun"); // send the form to the screen $form -> flush(); // the function witch handles the code after the form function doRun($data)  {    // show the selected gender    echo "Hello, you are a ";    switch($data["gender"])     {      case "m":        echo "boy.";        break;      case "f":        echo "girl.";        break;      default:        echo "shemale!! Whaaaaa...";        break;     } } ?>

If you want to set a default selected option, you can use the function SetValue.

In the example above that sould be:

<?php // default select the male option $form->SetValue("gender", "m"); ?>
