CakePHP : Form Radio Default Checked Value

Posted in CakePHP, PHP By Antonie Potgieter On April 17, 2008

With the CakePHP FormHelper, you can output a set or a list of radio button widgets.

Usage

<?= $form -> radio($field, $options, $attributes); ?>

Example

<?= $form -> radio('Model.field', array('Option1', 'Option2', 'Option3'), array('default' => 'option2')); ?>

In the line of code above, you’ll notice the default attribute value. This specifies the value of the radio button which will be checked by default in case there is currently no value passed through the model data.

    You can do something like this also…

    radio(‘Model.field’, array(‘option1′=>’option1′, ‘option2′=>’option2′), array(‘default’=>’option2′, ‘legend’=>false)); ?>

    radio(‘Model.field’, array(‘option1′=>’option1′, ‘option2′=>’option2′), array(‘default’=>’option2′, ‘legend’=>false)); ?>

    If you have a lot of radio buttons and they have the same values, you can set up $options = array(‘option1′=>’option1′, ‘option2′=>’option) then all you have to do is for each radio button put

    input(‘Model.field’, array(‘options’=>$options), array(‘default’ => ‘option2′)); ?>
