Form with Ajax and without I am constructing a form that is handled via Ajax. I need it to be avaible on browser where javascript isn't activated. For now, the submit part is like : 

$form ['submit'] = array (
  '#type' =&gt; 'button' ,
  '#ajax' =&gt; array (
      'callback' =&gt; 'MODULE_form_ajax_callback',
      'wrapper' =&gt; 'result-div' 
  ),
  '#value' =&gt; t ( 'Launch' ),
  '#weight' =&gt; 10000 
);


Has anyone resolved a similar issue ?

Thanks,
try to change '#type' =&gt; 'button' to '#type' =&gt;'submit' and then implement hook_form_submit()
