In Laravel, you can easily display the file names before submitting a form by using JavaScript. You can create an event listener for the file input field and then retrieve the selected file names when a file is selected. This way, you can dynamically display the selected file names on the page before the form is submitted. This provides a better user experience as users can see which files they have selected before completing the form submission.

What is a public directory in Laravel?
In Laravel, a public directory is the folder where all publicly accessible files are stored. This includes assets such as CSS, JavaScript, images, and other static files that need to be accessed directly by users. The public directory is the entry point for all incoming HTTP requests and should be the only directory accessible to the public through the web server. This helps to keep the rest of the application files secure and inaccessible to outside users.
What is a controller in Laravel?
In Laravel, a controller is a PHP class that is responsible for handling HTTP requests and returning responses. Controllers are primarily used to organize and group related request handling logic in a single class. They can perform various tasks such as processing input data, interacting with models to retrieve or update data, and returning views or JSON responses to the client.
Controllers in Laravel are typically stored in the app/Http/Controllers directory and can be created using the php artisan make:controller Artisan command. Each controller class contains methods that correspond to different actions that can be performed by the application, such as displaying a form, processing a form submission, or retrieving a specific resource.
By using controllers in Laravel, developers can keep their code organized, improve code reusability, and separate the concerns of different parts of the application. Additionally, controllers can be customized with middleware, which allows developers to apply common logic to multiple controller actions.
What is file moving in Laravel?
File moving in Laravel refers to the process of relocating a file from one directory to another within a Laravel application. This can be useful for organizing files or when files need to be stored in a different location. Laravel provides methods for moving files using the Storage facade, which allows developers to easily move files from one location to another without having to manually manipulate file paths.
What is file validation in Laravel?
File validation in Laravel is the process of ensuring that a file uploaded by a user meets certain criteria or requirements before it is accepted and processed by the application. This can include checking the file type, size, and other properties to ensure that it is safe to handle and meets the application's needs. Laravel provides built-in functionality for validating files using the validate() method or by using the file rule in a validation rule set. By using file validation, developers can improve the security and reliability of their applications by filtering out potentially harmful or invalid files before they are processed.
