An administrator has full control over the system. At the core of this PHP POS Inventory System project lies a robust admin panel. It serves as the centralized control hub, empowering administrators to manage all sides of the platform effortlessly. The admin can manage inventories, categories, and system users, and even search all the records. On top of that, the admin user can view sales reports as well. Speaking of sales reports, the user can view sales reports based on daily, weekly, monthly, and yearly (codeastro.com). Every record along with POS-related sales will contain its date information for accurate report generation. Besides, the administrator can only view their dashboard that presents overall records. Such as total items, sales, categories, and system users.

Inventory Management System

This PHP CodeIgniter Inventory management system project creates a captivating item showcase with all the required details. To add up inventories to the system, the user first needs to create an item category. Which only requires a naming field. After setting up some categories, everything is ready to go for the side of the inventory management system(codeastro.com). For adding inventory items, the user requires a couple of information. Such as the name of the item, its category, price per item, and a short description. After publishing the item, the user is then required to stock up each item, as by default all the items have initial 0 quantities. From the same inventory management section, the user can add up stock values or update the item, delete it, or search for the required items from the huge list.

Sales Report

One of the important features that belong to the POS and inventory management system is related to the integration of sales report features. Most POS systems today have these kinds of features for easy user interactions. Just like every other, this point of sale and inventory system project in PHP also contains simple sales report functions(codeastro.com). Under the sales report section, the user can view daily, weekly, monthly, and yearly sales reports. The system displays details such as sales date, items, description, total quantities, and amount of each sale made using the Point of sale system. The same concept goes to other parts such as weekly, monthly, and yearly where the data is shown based on dates and all. In addition to that, this particular section is linked with the POS system that is connected to this inventory management system project.

Point of Sale (POS)

Another important feature of this PHP project is about Point of sale system POS. Before anything else, only the cashier role users can access this. Cashiers are responsible for managing all the points of sale. This is only the features/access level for the cashier user roles(codeastro.com). In this POS System, the user can add items to the cart by entering the item name and quantities. All the cart items are visible before checking out along with the total amount due. During the checkout process, the user has to enter the total amount received, and if the amount received is less than due, the system alerts the user. Else, the payment is successful. In basic terms, the whole concept of this Point of Sale POS System is very simple and clear to comprehend.

User Management and Clerk Role

On the other hand, the admin users can manage system users. The admin has to provide details such as username, set password, and select roles for adding up new system users. About the user roles, there are a total of 3 user roles. Admin, clerk, and the cashier. Both roles of admin and cashier are mentioned above. The remaining clerk is almost similar to the admin one but with less control over the system. The user with a clerk role won’t be able to view dashboard counters for overall insights. The clerk user can add and manage inventories, view sales reports, and manage categories(codeastro.com). Management of system users is restricted for the clerk users as it is only available to the admin users. Also, the clerk users cannot use the POS system for the project. So basically, the role of clerk users is to manage inventories and view reports.

    —————————————————-
    A PHP Error was encountered
    Severity: 8192

    Message: Return type of CI_Session_files_driver::open($save_path, $name) should either be compatible with SessionHandlerInterface::open(string $path, string $name): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice

    Filename: ……………..

    1. Looks like there’s a compatibility issue related to the open() method in the Session_files_driver.php file. Might be due to mismatch between the PHP version that you are using. As mentioned in the project overview table and text files, this project works well with PHP 5 and 7

    1. Seems to be related to the session save path configuration. Might be due to changes in PHP versions, as the latest PHP versions may affect the behavior, requirements related to directory paths and permissions. The latest PHP versions might have different default settings for directory permissions which could affect the ability of PHP scripts to create directories or write data to them.
      As mentioned in the text files and project overview table, this project works well with PHP 5 and 7.
