In the at very beginning, we initialized variable name $error as blank.Although there is nothing terribly complex about the above process, it usually requires a significant amount of code, and to display error messages, various control structures are usually placed within the form HTML.Note: You can make web forms quickly with Simfatic Forms.Simfatic Forms helps you to make complete, feature rich web forms and get it online quickly. This generic PHP form validator script makes it very easy to add validations to your form.You may print some message after sending mail optionally.It is very essential to have the input to your form validated before taking the form submission data for further processing.

Each field in the form can have zero, one or more validations.

We will create a user registration form at first, and then we will validate fields of that form such as name, email, phone number, birth date, bio etc.

Client side form validation is done in user’s machine but server side form validation is done on server.

Form validation, while simple to create, is generally very messy and tedious to implement.

If you submit the form you should simply see the form reload.

In this example, you will need two files as below with correspondence names. These files are commented enough to understand what’s going on. We used text inputs, password inputs, number inputs, radio button inputs and a textarea input. This PHP syntax is shorthand for echoing a variable inline (see this post for more on PHP Shorthand Syntax) and “@” as prefix on any expression in PHP, any error messages that might be generated by that expression will be ignored.
