Hey guys, today in this post we are going to learn about How to create a form and validate all fields on a single click of button in lightning component.
Why are validation rules used?
We use form validation whenever we need to input information that is expected to some requirement from user.
There are two type of validation rule standards:- Server Side Validation and Client Side Validation.
Server Side Validation:- It is performed by server side. When we click on a button the button functionality call a method that is connected through server and it’s get all information from server.
Client Side Validation:- Client side validation performed by JavaScript function. Where does not need to connect to server. It is working very fast because it helps to reduce the server side lode.
In this example I am creating a client side validation. So go through the below points step by step.

FAQ (Frequently Asked Questions)
How do you display validation error in lightning component?
To programmatically set and display an error message on a field, use the setCustomValidity() and reportValidity() methods available on the base components. For more information, see the lightning:input documentation.
How do you make fields required in aura?
To make an input field required on the client only, set required attribute to true in lightning:inputField . Use this attribute if you want to require a value in a field before the form can be submitted, and the field isn't marked required in Setup.
How do you display toast message in LWC?
A toast can also simply provide information. To display a toast notification in Lightning Experience or Experience Builder sites, import ShowToastEvent from the lightning/platformShowToastEvent module. The lwc-recipes repo has a component that lets you customize and send a toast so that you can try out the variations.
