Views exposed form delta
You can achieve this goal via implementing hook_form_alter

Let e.g.

/**
 * Implements hook_form_alter().
 */
function MYMODULE_form_alter(&amp;$form, &amp;$form_state, $form_id) {

    if ($form_id == 'views_exposed_form' &amp;&amp; $form_state['view']-&gt;name == 'test' &amp;&amp; $form_state['view']-&gt;current_display == 'page_1') {
       // do your alteration stuff
    }
    if ($form_id == 'views_exposed_form' &amp;&amp; $form_state['view']-&gt;name == 'test' &amp;&amp; $form_state['view']-&gt;current_display == 'page_2') {
       // do your alteration stuff 
    }
}
