Actually, the example I thought of was done with two separate widgets. But I
found another, a form where the user can enter measurements in a choice of
units (inches or centimeters). The etWidgetFormJQuerySliderWithUnits widget
renders a jQuery UI slider. The unit widget is used over several measurements.
If one unit select is changed, all others and all entered values are changed
with JavaScript.
I declare the unit widget as sfWidgetFormSelect and then include it in the
other widgets as an option. Its default value is another option:
$this->setWidget( 'units', new sfWidgetFormSelect( array( 'choices' =>
sfConfig::get( 'app_lookup_units' ) ) );
$this->setWidget( 'neck_girth', new etWidgetFormJQuerySliderWithUnits( array(
'min' => 200, 'max' => 500, 'step' => 5, 'units' =>
$this->widgetSchema['units'], 'unit' => 10 ) ) );
$this->setWidget( 'head_girth', new etWidgetFormJQuerySliderWithUnits( array(
'min' => 200, 'max' => 500, 'step' => 5, 'units' =>
$this->widgetSchema['units'], 'unit' => 10 ) ) );
in updateDefaultsFromObject(), the default unit can be set:
if ( isset( $this->widgetSchema['neck_girth'] ) )
{
$this->widgetSchema['neck_girth']->setOption( 'unit',
$this->object->getUnit() );
}
The bind / clean process does not affect the included widget, so its value must
be collected in updateObject():
if ( array_key_exists( 'neck_girth', $values['units'] ) )
{
$this->object->setUnit( $values['units']['neck_girth'] );
}
can't send you the link because the site is not yet live. The solution works,
but I found it rather cumbersome, I wouldn't do this if it wasn't for the
interface interactivity.
