About CActiveForm in document is:(clientOptions section)
ajaxVar: string, the name of the parameter indicating the request is an AJAX request. When the AJAX validation is triggered, a parameter named as this property will be sent together with the other form data to the server. The parameter value is the form ID. The server side can then detect who triggers the AJAX validation and react accordingly. Defaults to ‘ajax’.
Now take a look in my example: Summary: i have a form with two fields mail and newEmail , i submitted form via ajaxSubmitButton (if you need form code tell me put it). In following i get var_dump($_POST) content in two state:
First: Following var_dump($_POST) is for when a field(newEmail) is left empty:
array
'User' =>
array
'email' => string 'user@gmail.com' (length=14)
'newEmail' => string '' (length=0)
Second: Following var_dump($_POST) is for when all the fields are filled:
array
'User' =>
array
'email' => string 'user@gmail.com' (length=14)
'newEmail' => string 'admin@minudasht.net' (length=19)
'ajax' => string 'email-form' (length=10)
'yt0' => string 'update' (length=18)
As you see only when all fields are filled the ajaxVar(ajax) exist in $_POST. When ajaxVar(ajax) initialized in CActiveForm ?
