Hello,
I'd like to add an custom validation in my forms using JavaScript and DataExtension. With 'normal' fields everything works fine, but when I try to do the same thing with DataExtension, JavaScript can't see variable.

My code looks like this:

SiteConfigExtension.php:

class SiteConfigExtension extends DataExtension
{
    private static $db = array(   
      'MainQuoteModal__Message' => 'Text',
    );
}

HomePage.php Controller

  public function init() {
    parent::init();

    Requirements::javascriptTemplate($this->ThemeDir().'/js/script.js', array(
      'MainQuoteModal__Message' => $this->MainQuoteModal__Message
    ));
  }

Script.js

    var validationObj = {
        firstName: {
            identifier: 'first-name',
            rules: [{
                type: 'empty',
                prompt: '(my variable)'
            }]
        }
    };

Since I need to add 'SiteConfig' before any field name in my template I don't how to use this in my script.js

I've tried:
prompt: '$MainQuoteModal__Message'
prompt: '$SiteConfig.MainQuoteModal__Message'
prompt: '$SiteConfig+MainQuoteModal__Message'

but none of the works here. I think JS need to 'somehow' recognize "SiteConfig" but I don't actually know how to write that.

UPDATE:
I've met another problem, this custom validation works only in my HomePage and supposed to work on every page.

Any help will be appreciated.

It seems you're applying the message to be set in SiteConfig, yet in your HomePage class, you address $this.

To have it on every page, add the array to the Page init. And have it read the message from the appropriate class. In this case, SiteConfig::current_siteconfig()->FieldName

Hi Spehere,
thanks for your reply. I moved my init form HomePage.php to Page.php and I'm trying fo figure out where to put your snippet. I've tried something like this:

Page.php

class Page_Controller extends ContentController
{
    public function init()
    {
        parent::init();        
        Requirements::javascriptTemplate($this->ThemeDir().'/js/script.js', array(
            'ValidationMsg__Empty' => SiteConfig::current_site_config()->ValidationMsg__Empty
        ));
    }
}

Code is executing properly, but stll no luck with working validation on all pages. Still only form at HomePage giving proper validation message. On the other pages after submit, form just sending message, even with empty fields. Any additional help would be appreciated.

Cheers,
Darek.
