Project: Simple Inventory System Using PHP/MySQLi with Source Code

About

I developed this code for those beginner programmers who found difficulties in creating their inventory system using PHP/MySQLi. The has a secure login because I have used md5 encryption for login and registration. It also generates reports such as daily, weekly, monthly, and yearly. To try this system just download and run this system. The inventory table or the list of products on the inventory page will serve also as the form for the sales. The use will select a product then by clicking the row, the product quantity sold cell will change into a text area where can the user enter the quantity sold, and by clicking anywhere on the page the value of the quantity sold input will be automatically saved in the database without leaving or refreshing the page.

Features

  • Login Page
    • The page where the system users submit their system credentials to access the data and functionalities of the simple inventory system.
  • Registration Panel
    • This panel can be navigated by clicking the register ribbon at the top-right of the Login panel. This page is the form for creating a new system user and this requires the admin password.
  • Inventory Page
    • The page where the users will be redirected by default after logging into the system. This page displays the list of products and their details and at the same time, each row has a live editing feature and serves as the sale transaction form of the system.
  • Sales Page
    • The page where the total sales within the 2 selected dates are being displayed.
  • Add Item Page
    • The page where can system users add new stock for each product.
  • Add Product Page
    • The page where the system users submit the new product details.
  • Edit Price Page
    • The page where the system users update the price of the product.

How to Run

  1. Download the source code and extract the zip file.
  2. Download or set up any local web server that runs PHP script.
  3. Open the web-server database and create a new database name it "liveedit".
  4. Import the SQL file located in the database folder of the source code.
  5. Copy and paste the source code to the location where your local web server accessing your local projects. Example for XAMPP('C:\xampp\htdocs')
  6. Open a web browser and browse the project. E.g [http://localhost/inventory]

Default Admin Access

Username: admin
Password: admin

Hi. Am I using the correct username and password? I use "admin" for both but I get an error message that username and password not found. I tried entering "3", "admin", "admin" on the register form based on the value on the database but it says "You dont have access to add user pls. contact the administrator".

Hi Argie, Great code but I do have a question though. On the add item, instead of adding the stock, the app just updates the value of qtyleft. For example the product "qweqwqw" has 10 on qtyleft and if I go to add item and put 15 on quantity, I would like qweqwqw to become 25 instead of 15. How do I go about this? Thanks. Hoping for your reply. -Renee

thanks argie! to all those who are complaining - password, some features not working, blahblah.. why don't you all try to put an effort in reading the code and do a little bug fixing. yes, there are some minor bugs but otherwise argie's work is fine. sheesh! for one thing, the login, of course, will not work if you haven't damn loaded the SQL file.

something wrong with your database when i import it on mysql
Submitted byMasterFerdz (not verified)on Wed, 03/25/2015 - 02:15

If you will check and read the sql there is nothing wrong with it. if import is not working for you, just manually encode the sql code and the run it.

This is very close to what I was looking for - close enough that I can pull snippets from here and there. It took all of 5 minutes to realize that I needed to add the following to the liveedit.sql: CREATE DATABASE `liveedit`; USE `liveedit`; and change the user and password in db.php.

Submitted byChammburger (not verified)on Fri, 11/27/2015 - 10:17

Remove the empty lines and spaces at the beginning of login.php. The opening block of the php function should be the first think in the page. I had two blank lines when I installed. The error went away after deleting the two empty lines.
