I want to insert the records in two table with perfect validation.But my validation part in not working perfectly.That means when u see my view page u'll see sender information,receiver information,money which is wrapped by html legend.I want to do validation required field at a time after clicking submit button.In this code whats happening is that when i press submit button sender information validation is working but receiver information portion validation is not working.when i put any value in sender portion,that time receiver information portion's validation works only.What should i have to do?

Answer 1

First of all; apparently there is a 'relation' between the 'sender' and 'receiver' in your application, but NOT in your model/database definition. Relying on the 'auto-incrementing' ID of your database (e.g. receiver 1 and sender 1 belong together) is not reliable. Auto-incrementing IDs will come 'out of sync' between both tables and you will end up with a situation where 'receiver 123' should actually be 'connected' to 'sender 125'.
If I understand correctly what this form does, is create a 'money transaction' in the database. Sender and Receiver should (in this case) probably not be stored in separate databases, unless you're going to offer an option to 'pick' an existing sender/receiver from a list.
In both situations there should be a table/model in your application that 'connects' the two, otherwise you will just have a random list of people 'sending' and 'receiving' money, but no way to know which person wants to send money to which recipient
If you're not going to 're-use' the senders/receivers, than a correct database-design should be something like:
id| sender_name | sender_email | sender_address | receiver_name | receiver_email | receiver_address
1 | Amid | 1#1.com | Parkstreet | SOS | 2#2.com | park 1
I would name this table 'money transfers' and the model 'Moneytransfer'
Having both in 1 model will simplify the validation and will guarantee that both sender and receiver info is present and correct.
If you really want to manually save two separate records (Based on my explanation above, I would strongly advise you to not do this) you should do this;
validate both records manually via $this->Mymodel->validates($data)
enclose both saves in a transaction and rollback if one of them fails
More information on manually validating inside your controller can be found here:
http://book.cakephp.org/2.0/en/models/data-validation/validating-data-from-the-controller.html
More information on using transactions in CakePHP can be found here:
http://book.cakephp.org/2.0/en/models/transactions.html
[update]
Browsing further through your 'form', there 'seems' to be a 'transaction' model as well?
If this is the case and the Model-relations are properly defined in CakePHP, you will be able to save all related records using Model::saveAssociated(). This will also enclose all saves in a transaction (atomic)
