Validating form data using hidden fields dg dating profile
Ideally, users will fill the web form with necessary information and finish their job successfully. In this article we will go beyond the validation itself and explore different validation and error feedback techniques, methods and approaches.
The goal of web form validation is to ensure that the user provided necessary and properly formatted information needed to successfully complete an operation.
This can be useful to you when deciding on required fields.
Apart from ensuring that users provide necessary information, validation has to ensure that users provide information in the correct format.
The user just wants to get something done, not think about “correct” formats and complex UIs.
Let the user type whatever he needs, and if it’s reasonable, make the software do the right thing with it.
This design pattern is also often called forgiving format UI design pattern.
We’ll discuss some other format techniques later in the article.
Main drawback of client-side validation is that it relies on Java Script.
This type of validation is done on the client using script languages such as Java Script.
By using script languages user’s input can be validated as they type.
This is the reason why it is a good practice to either put a note on the top of the form that indicates that all fields marked with an asterisk are required or to use required field markers.
In case that all fields are required there is no need to place asterisks or markers in the form.
On the other hand, users will have to fill in the information without getting a response until they submit the form. Validation in this context refers to validating rules such as username availability.
