     error_reporting(E_ALL);
     ini_set('display_errors', 1);   
     // webform_client_form_52  webform id
     if($form_id == 'webform_client_form_52') {     
         $form['submitted']['send_a_mail_yourself'] = array(
         '#type' =&gt; checkbox,
         '#form_key' =&gt; 'send_a_mail_yourself',
         '#title'=&gt; 'Send a copy of yourself',
         '#weight' =&gt; 4, // As your needed
         '#field_prefix' =&gt; '&lt;div id=\'send_a_mail_yourself\'&gt;',
         '#field_suffix' =&gt; '&lt;/div&gt;',
         '#default_value' =&gt; array('yes' =&gt; t('send a copy of yourself')),
       );
       $form['#submit'][] = '_sendmail_webform_submit';

       }
     }

   function _sendmail_webform_submit($form, &amp;$form_state) {        
     $param = array();
     foreach($form_state['input']['submitted'] as $key =&gt; $values) {
        if(valid_email_address($values)) {
             $to = $values; //to email address

        } else {
          if($values) {
