Validating form php
First, create a Let's assume our web application is for game collectors.
If a game collector registers with our application and they own more than 100 games, we want them to explain why they own so many games.
If the entered data follows all those rules, it is considered valid; if not, it is considered invalid.
When an element is valid: If you want to take control over the look and feel of native error message, or if you want to deal with browsers that do not support HTML's built-in form validation, you must use Java Script.
As mentioned previously, Laravel will automatically redirect the user back to their previous location.
For example, consider an "update profile" screen that includes the user's name, e-mail address, and location.
Of course, you will want to verify that the e-mail address is unique.
However, if the user only changes the name field and not the e-mail field, you do not want a validation error to be thrown because the user is already the owner of the e-mail address.
If so, it allows it to be submitted to the server and (usually) saved in a database; if not, it gives you error messages to explain what you've done wrong (provided you've done it right).
Form validation can be implemented in a number of different ways.
