What is client-side validation VS server side validation?
Server side validation is mainly used to validate and display form level errors, while client side validation is used for field level errors. Client side validation depends on javascript and may be turned off in some browser, which can lead to invalid data saved, while server side validation is very secure.
Is server side or client-side validation better?
Yes, client side validation can be totally bypassed, always. You need to do both, client side to provide a better user experience, and server side to be sure that the input you get is actually validated and not just supposedly validated by the client.
What is basic validation?
Basic Validation − First of all, the form must be checked to make sure all the mandatory fields are filled in. It would require just a loop through each field in the form and check for data. Data Format Validation − Secondly, the data that is entered must be checked for correct form and value.
Is client-side validation really all that important, always?
Server side validation is absolutely necessary. Client side validation is purely a user experience improvement since the same validation should always happen on the server anyway. After all, you can always disable JavaScript or simply post arbitrary data directly via HTTP.
Do not rely on client-side validation?
Do not rely on client-side validation because it can be easily bypassed. For example, a malicious user could disable your client-side script routines by disabling JavaScript. Use client-side validation in addition to server-side validation to reduce round trips to the server and to improve the user experience. [edit]
