Is it possible to validate container fields?

Hello,

Is it possible to validate container fields?

I have a page in my Xataface application with 3 file attachment container fields. I wrote a delegate class validation function to check if the user has entered filenames for uploading. The POST variables are always blank for these container fields:

$_POST['source_attachment_1']
$_POST['source_attachment_2']
$_POST['source_attachment_3']

Is it possible to validate container fields?

Bonjour,

Why not use a regex like in this example ?

Code: Select all

[filefield]
validators:regex = "/(.*)[\/\\]([^\/\\]+\.\w+)$/"
validators:regex:message = "any message"

I did not test the regex.

Hello,

Thanks for the suggestion. Unfortunately, I have an unusual requirement where the attachment fields are only required based on another field (status).

If status = 'x' then no attachment is required
If status = 'y' then at least 1 attachment is required
If status = 'z' then at least 2 attachments are required

Because of the unusual requirement I figure I need to code the validation in the table's delegate class.

You could do this using javascript rather than validation.

E.g. Create a javascript onchange handler for your status field that hides or shows the container fields according to status. Here is a similar example where I have a select list to choose between paypal and cheque, and two text fields "Cheque payable to", and "Paypal address", where the correct field shows up according to what is selected in the select list. So I create a javascript file:

Code: Select all

jQuery(document).ready(function($){
   
   
   if (typeof(swete) == 'undefined' ) swete = {};
   if ( typeof(swete.tables) == 'undefined')  swete.tables = {};
   swete.tables.affiliate_accounts = {
   
      updatePaymentFields: function(sel){
         if ( jQuery(sel).val() == 'Paypal'){
            jQuery('#paypal_address_form_row').css('display','');
            jQuery('#cheque_payable_to_form_row').css('display','none');
         } else if ( jQuery(sel).val() == 'Cheque' ){
            jQuery('#paypal_address_form_row').css('display','none');
            jQuery('#cheque_payable_to_form_row').css('display','');
         } else {
            jQuery('#paypal_address_form_row').css('display','none');
            jQuery('#cheque_payable_to_form_row').css('display','none');
         }
      }
   };
   
   swete.tables.affiliate_accounts.updatePaymentFields(
      $('#payment_method').get(0)
   );

});


This uses Jquery to make things easier. Jquery is distributed in js/jquery.packed.js.

Then I just include this javascript file before the new and edit record forms by implementing the following in the delegate class:

Code: Select all

function block__before_new_record_form(){
      echo "<script type=\"text/javascript\" src=\"".df_absolute_url(DATAFACE_SITE_URL.'/tables/affiliate_accounts/af
   }
   
   function block__before_edit_record_form(){
      echo "<script type=\"text/javascript\" src=\"".df_absolute_url(DATAFACE_SITE_URL.'/tables/affiliate_accounts/affiliate_accounts.js').'"></script>';

      );
   }
