   Hi,

   I've searched throught the forums a bit but can't find any info. I have a 5 choices in a multiple choice entry. I need the use to be able to select any two multiple choice answers

   Is this possible? I know I can use checkboxes but a user can then tick as many as they like.

   Any help greatly appreciated.

   Hi,

   Multiple selection in "multiple choice" field it not possible, however you can use a "check box fiald" and add a custom validation to the field, so your user will allowed to fill 2 options. To do so, you need to edit "includes/post-functions.php" file, go to around line 614 ~ 624 you'll see these code :

   foreach ($all_child_array as $i){
   
   	//save old data into array, for form redisplay in case errors occured
   	$form_data[$base_element_name.$i]['default_value']   = $user_input[$base_element_name.$i];
   
   	//prepare data for table column
   	$table_data[$base_element_name.$i] = $user_input[$base_element_name.$i];
   
   }

   then replace the code with this

   $count_value = 0;
   foreach ($all_child_array as $i){
   
   	//save old data into array, for form redisplay in case errors occured
   	$form_data[$base_element_name.$i]['default_value']   = $user_input[$base_element_name.$i];
   
   	//prepare data for table column
   	$table_data[$base_element_name.$i] = $user_input[$base_element_name.$i];
   	if ($user_input[$base_element_name.$i] != '' or !empty($user_input[$base_element_name.$i])) {
   		$count_value++;
   	}
   }
   
   if ($count_value <> 2) {
   	if ($form_id == 5 && $element_id == 1)
   		$error_elements[$element_id] = 'You only need to choose 2 options';
   }

   in there I assume you've the field with element id 1 in form id 5, so you need to change those ID with yours

   I've just tried this and the validation works fine, but when I correct and submit the form I get this message:

   Error sending email: SMTP Error: The following recipients failed: {element_2}
   Warning: Cannot modify header information - headers already sent by (output started at /home/ihbconli/public_html/machnew/machform2/includes/helper-functions.php:482) in /home/ihbconli/public_html/machnew/machform2/confirm.php on line 38

   However, the form submission is sent successfully, but the error message would put most users off.

   The same form sent fine before I did the alterations. I get the same error message if I attempt to send the form with the correct number of boxes ticked, if that helps.

   Can anyone help? I would love to use this addition,

   Peter

   Hi Peter,

   From the error message :

   Error sending email: SMTP Error: The following recipients failed: {element_2}

   It seems the problem come from your mail setting. To fix it, try to re-set form mail setting and then try to submit the form again.

   Anyway if you restore the file to original state, will it solve the problem ? I think the problem not come from this customization

   This is not working for me. I changed the element ID and form ID. The error message defaults to the "required" message, and when I select only one of the checkboxes, it still throws an error. Has something changed since this was posted?

   Can someone tell me if this is still actual. I can imagine this will be an option in a new release?
