When creating an online community, website, or social profile, it can be challenging to come up with a username that’s not already taken.
If the username is available, then the user can proceed with registration. If it isn’t, then the user must have to try again with a new username until they find one that is available.
This post will help you check username availability using JavaScript and PHP.
I am using the MySQL database in this tutorial.
Database is used to store and maintain data. Based on stored data generate report, perform actions, etc.
You can also use it to manage the collection of related files. For this, you can either create a new table or update the existing table to store file information.
In this post, I will show you how to upload file and store to PostgreSQL database with PHP.
If you allow the users to upload profile, product, items photos, or documents and during updating file process if you are not deleting the previously uploaded file then in that case files keep getting stored and occupying space on the server.
In this tutorial, I am only covering file deletion not file upload. You can view this tutorial for file upload in Laravel.
DataTable by default has a single search box that uses for searching globally.
If default search filter is not fulfilling your requirement then you can customize and add you own filter elements like – dropdown, date filter, textbox, etc.
In this tutorial, I show how you can add custom filter in DataTable AJAX pagination in Laravel 9.
