enableAjaxValidation and enableClientValidation in Yii CActiveForm Widget
When enableAjaxValidation set to true, it makes the form doesn't refresh the page to validate form input. So, it will send an ajax response, when we submit the form.
While enableClientValidation allows us to validate form input via javascript if possible.
And don't forget to set validateOnSubmit to true in clientOptions property.
To make it clearer, below several case given.
1. enableAjaxValidation=false and enableClientValidation=false
Every submission of form will refresh or request page to validate form input.
2. enableAjaxValidation=false and enableClientValidation=true
Every input which is possible to be validated like required field, email field will be handled by javascript, before processing to request/refresh page to server.
3. enableAjaxValidation=true and enableClientValidation=false
Every input will be validated by server side but will not refresh the page, it will do an ajax request for validation.
4. enableAjaxValidation=true and enableClientValidation=true
This one will do an ajax request after doing some possible validation via javascript, like I said before, such as checking required field or email field. And another type of validation like duplicate checking will be handle by an ajax request to server.
This is code snippet for instantiating a Yii CActiveForm widget in case no. 4.
