Add CSS attributes to Symfony form labels?

Question

Hi,

I try to add some css attributes to labels in my custom sfForm but I can't achieve it.

In my custom class myForm extends sfForm, I create all textfields dynamically:

public function configure()
{
    $widgetFixtures = array();
    foreach ($fixtures as $fixture) {  
     $widgetFixtures[$fixture->getId()] = new sfWidgetFormInputText(  
            array('label' => $fixture->getTeamNameDom()),  
            // I would like to add something like: array('class' => $fixture->getCSS()),
            array('value' => $fixture->getScore1(), 'readonly' => 'readonly')
            );
    }
    $this->setWidgets($widgetFixtures);
}

I tried to format the rendering with setFormFormatterName but without success.

Note: I can't use renderLabel($value, $attributes = array()) in the template because I get the CSS class from the DB (as you may have seen, I have to use: $fixture->getCSS()).

Could someone shed my light?

Many thanks.

What you're trying to do seems possible but your greyed out syntax seems a little off. Try this:

    $widgetFixtures[$fixture->getId()] = new sfWidgetFormInputText(  
        array('label' => $fixture->getTeamNameDom()),  
        array('class' => $fixture->getCSS()),
        array('value' => $fixture->getScore1(), 'readonly' => 'readonly')
    );

... or check "The sfWidgetForm Base Class" section here: http://www.symfony-project.org/forms/1_4/en/A-Widgets

The class attribute needs to be passed in as an array in the second parameter for all form widgets.

$this->setWidget('foo', new sfWidgetFormInputText(array(),array('class','fooclass'));

You could try overriding the widget class if you want to add CSS to labels - specifically the methods that render the label. You could then do something like

$foo = new myWidgetFormInputText(array("myCSSClass" => $fixture->getCSS()));

and then override your renderLabel() method or similar in your widget. Your widget will have access to the options you pass in - in the above example myCSSClass is the option key. You can then apply this class value to your widget's label.

Here is how I solved it.
I took both suggestions from johnwards and richsage and put them together :
"This sort of stuff should be handled in the view/action."
"Access to the options/attributes passed to the Widget itself."

First, I add the CSS class to the input itself (even if I will not use it).

In my custom class myForm extends sfForm,

foreach ($fixtures as $fixture) {    
     $widgetFixtures[$fixture->getId()] = new sfWidgetFormInputText(  
         array('label' => $fixture->getTeamNameDom()),  
         array('value' => $fixture->getScore1(), 
               'readonly' => 'readonly',  
               'class' => $fixture->getCSS())  
         );  
}  

Then, in the template, instead of using echo $form;, I add the CSS class to the label as shown below:

foreach ($form as $widgetId => $widget) {  
    ...
    $labelClass = $widget->getWidget()->getAttribute('class');  
    echo '<td>'.$widget->renderLabel(null, array('class' => $labelClass)).'</td>';  
    ...
}

Maybe it is not the best way to solve this issue but it works.

Thanks all for your feedback!
