If you want to add button to your forms, you can use the inputType submit
(symfony2.3 and more)
Documentation
$builder->add('save', 'submit', array(
'attr' => array('class' => 'submit'),
'label' => "click to go next"
));
You have also the reset
and button
inputType.
button
html tag is more recommended than input
tag, it's more flexible (you can use an image as a button for example).
If you really want a <input type="submit"
rather than <button type="submit"
, you can add your own inputType to symfony as descripted there in the cookbook
