Html code for validating forms

For example, in an email form field, instead of entering a valid email address, the user might enter an invalid one or malicious data obviously ignoring the intent of the request.

When it comes to validating form values, it can be done on the client-side (web browser) and on the server-side (using your preferred server-side language).

By adding this attribute to a form field, the browser requires the user to enter data into that field before submitting the form.

This replaces the basic form validation currently implemented with Java Script, making things a little more usable and saving us some development time.

Today, regular expressions are included in most programming languages, as well as in many scripting languages, editors, applications, databases, and command-line tools.

Regular expressions (Reg EX) provide a powerful, concise, and flexible means for matching strings of text such as particular characters, words, or patterns of characters.

By passing a Reg EX string as the value for the attribute, you can dictate what value is acceptable by the form field and also inform the user of errors.
