Question

I want to change the value of other 2 fields on checking the checkbox.

I have a field called “Cancelquery”->checkbox.
If its checked then i want to

1. automatically set the value of the field “Status” -> Cancelled and
2. automatically select value of the “Reason” field to be “Other”.

Am using model for this fields so the name and id of each field is created automatically.

Eg. $form->checkBox($model,'CancelQuery')

Any help?

You’ve to specify the additional html options that you want for your checkbox to be rendered. In your case you can try the following:

echo $form->checkBox($model,'CancelQuery',array('onchange'=>'doOtherThings(this);'));
echo $form->textField($model, 'status', array('id'=>'status'));
echo $form->textField($model, 'reason', array('id'=>'reason'));

And in your js zone, a function like the following:

function doOtherThings(element){
    var checked = $(element).is(':checked');
    if (checked) {
        $('#status').val('Cancelled');
        $('#reason').val('Other');
    } else {
        // reset values
        $('#status').val('');
        $('#reason').val('');
    }
}
