Hi.

In order to custom the validation messages (javascript ones or others) the only way is to mess up with sapphire files ?
aka Sapphire/Forms/EmailField.php and/or Sapphire/Lang/en_EN.php ?

Any way to properly override the $lang array ?

Thanks for any hint.
Be safe.

I've been looking for that as well, but I'm afraid that's the only solution.
Still hoping I'm wrong

So, I managed to modify texts and translations from within my controller, and thus avoiding to mess up with Sapphire.
It's not an elegant solution but it works.

There are 2 issues :
- It's not possible to set a specific required-validation text for each field. A global "%s is required" is the only option I'm aware of.
- For the Javascript required-validations, you have to target the field by their Html IDs. Those IDs can change if you modify the form in the CMS.

class ContactPage_Controller extends UserDefinedForm_Controller {
	
public function init() {
	parent::init();

	global $lang;

	// Php and Javascript formating-validations for email fields
	$lang['en_US']['EmailField']['VALIDATION'] = $lang['en_US']['EmailField']['VALIDATIONJS'] = 'It seams your email address is not really valid.';

	// Php required-validations
	$lang['en_US']['Form']['FIELDISREQUIRED'] = 'Could you please fill the field %s because it\'s important to us';

	// Javascript required-validations for each field
	Requirements::customScript( "
		if( typeof Behaviour != 'undefined') {
			Behaviour.register({
				'#Form_Form_EditableTextField2' : { requiredErrorMsg: 'Knowing who you are is important to us. Please give us a name, and your company\'s one too, if applicable.' },
				'#Form_Form_EditableEmailField4' : { requiredErrorMsg: 'Please give us your email address, or we sadly won\'t be able ton get in touch with you.' }
			}); // register()
		} // if != undefined
	"); // customScript()
} // init()
} // ContactPage_Controller

Didn't know that. That's pretty cool!
