Throughout the tutorial, we'll explain each step in detail and provide code examples for you to follow along. By the end, you'll have a solid understanding of form handling and validation in Laravel, empowering you to build robust and secure web applications.

What if a validation depends "if it has been changed" and "I want to check if it is still unique in the table or not".
Now I do validation in the Controller where I put all the validations in an array. Then add item in it depending on the requirement. Finally do the validation.
Example code bellow:
// Add all the validation here
$validationList = array(
'title' => 'required|max:255',
'category' => 'required',
);
// Add "Unique" to validation if current validation is not equals to the old one.
if($req->postSlug != $getSingle->slug) {
$validationList['slug'] = 'required|unique:blogs,slug|max:255';
} else {
$validationList['slug'] = 'required|max:255';
}
// Do validation depending on the array "$validationList"
$req->validate($validationList);

[@ajay-yadav]

check this code
$req->validate([
'slug' => [
'required',
'max:255',
Rule::unique('blogs', 'slug')->ignore($getSingle->id),
],
'title' => 'required|max:255',
'category' => 'required',
]);

@@ajay-yadav Thank you for the reply.
I didn't know we can add validation like this.
But my question was how can I add this dependency in the custom request like you created.
