Our Database tutorials are up to date and well explained step-by-step using examples so you can learn Database manipulation fast.
CSV files are easier to maintain and can be used for export and import data in the web application.
For data import first, need to allow the users to browse and upload the file. In CodeIgniter, there is upload library available that makes it easier to handle file uploads.
In this tutorial, I show how you can import data of CSV file in the MySQL database table in the CodeIgniter 3 project.
You can store the image files in the Database table either in base64 format or its path after uploading.
In the base64 method, it is not necessary to store the uploaded file on the server because it is been directly accessed with the base64 encoded value.
In this tutorial, I am using PDO connection for storing multiple image files path in the MySQL database table.
You normally store the user-selected files in a specific directory but the same directory is also used by all other users.
If you are allowing to upload multiple types of files like – images, videos, doc, etc then it becomes a mess.
To avoid this you can create separate directories to store files in an organized way.
But for storing it in a more organized way you can dynamically create directories for each user for storing their files. This makes traversing to file easier.
Sometimes it requires to quickly create a clone of the MySQL database while working on the project either for the backup purpose, using it on a copy of the project, or moving the project.
With phpMyAdmin, this process is easier.
In this tutorial, I am assuming that you already have a cPanel enabled web hosting server.
