  1. The enumRadioButtonList activeRadioButtonList
  2. Adding it to giix' CrudCode

Let's say our table 'mug' has a column named 'color' of the type ENUM('red','green','blue').
We want to replace the textfield for the attribute color in the create and update forms of a 'mug' with a Radio Button List, which has the enum values as options.
This is a rewrite of c@cba in the wiki article of enumDropdownList
The main code was contributed by zaccaria in the forum (see this post).

I merely repeat that useful peace of code here, so it is available in the wikis, and describe how you can incorporate it into giix, so the Radio button list is added automatically during code generation.

The enumRadioButtonList activeRadioButtonList

Create the file ..\components\RBLHtml.php with the following code:

class RBLHtml extends CHtml
	public static function enumRadioButtonList($model, $attribute, $htmlOptions=array())
	  return CHtml::activeRadioButtonList( $model, $attribute, self::enumItem($model,  $attribute), $htmlOptions);
	public static function enumItem($model,$attribute) {
		foreach(explode(',', $matches[1]) as $value) {
		return $values;

Then use it in the view files with:

<?php echo ZHtml::enumRadioButtonList( $model,'color' ); ?>

Adding it to giix' CrudCode

If you use giix for code generation, you can put the code above into the file ..\extensions\giix-components\GxHtml.php (only the function definitions, not the 'class' part).

Then add the following code into the file ..\extensions\giix-components\GxActiveForm.php:

public function enumRadioButtonList($model, $attribute, $htmlOptions = array()){
		return GxHtml::enumRadioButtonList($model, $attribute, $htmlOptions);

Now you can use it in your view files with:

<?php echo $form->enumRadioButtonList($model, 'color')); ?>

To edit giix so it adds this line into the view files during code generation: in the file ..\extensions\giix-core\giixCrud\GiixCrudCode.php find the function generateActiveField. Add the condition for the enum type (enclosed between /*NEW_BEGIN* and /*NEW_END*/) into the code, so it looks like:

if (strtoupper($column->dbType) == 'TINYINT(1)'
		|| strtoupper($column->dbType) == 'BIT'
		|| strtoupper($column->dbType) == 'BOOL'
		|| strtoupper($column->dbType) == 'BOOLEAN') {
	return "echo \$form->checkBox(\$model, '{$column->name}')";
else if (stripos($column->dbType, 'enum') !== false) {
	return "echo \$form->enumRadioButtonList(\$model, '{$column->name}')";
} /*NEW_END*/
else if (strtoupper($column->dbType) == 'DATE') {

That's it. If something is unclear/wrong/incomplete or you have other suggestions please let me know.
