data loss after form sent
8 July 2011 at 2:10am
Hello everyone,
can anybody point me at a solution how to persist data from form, when this form is sent and something failed, validation for example?
Simple example:
I have DataObject bounded to Page with one to many relationship like in this doc: http://doc.silverstripe.org/sapphire/en/tutorials/5-dataobject-relationship-management.If one of this fields: http://doc.silverstripe.org//src/sapphire_2.4/docs/en/tutorials/_images/gsoc-student-creation.jpg would be required (for example First Name) and i try to add new student without filling this required field, whole form will be submited, an error message will show up and all data from form are lost. How can I prevent this behaviour?

Hi swaiba,
thanks for your answer, in my case, I found data from my form in
Session::get('FormInfo.BannerDataObjectManager_Popup_AddForm.data');
But I don't know how can I access form object in DataObject::getCMSFields method. It is possible anyway?
There is only FormField::setValue method (or constructor third parameter) on field object, but this is not working, neither FieldSet::setValues. I think, this is not working, because values are overwritten in Form::loadDataFrom and thats called from CMSMain::getEditForm.

I think you should be able to access the session at any point, but I don't know if there will be anything in it... that specfication is new to me.Personally I have never had this issue within the CMS, using plain model admin by creating my own validator and I don't need to worry about the session stuff....

Yes, yes, I can access session data, thats not a problem (and thanks for info about this).Validation works too, but if form validation failed (for example, i don't fill required field), every data I filled in form are lost and I have to fill whole form again and thats annoying - especially for my client

I think it's a DOM issue then... So I'd encourage you to post in that section...

Oh, and is there way to move this topic to another section, or may I submit new?
Swaiba, anyway, thanks for your help with analysing my problem!
