Simple Inventory System Using PHP/MySQL


I developed this code to those beginner programmer who found difficulties in creating their inventory system using php/mysql. The feature of this system are, it generates daily inventory report, secure login because i use md5 encryption for login and registration . It also generate reports such as daily, weekly, monthly, and yearly. This system has many features not just the features written above. To try this system just download and run this system. If you have question, suggestion or anything, just leave comment and it's my pleasure to entertain your comments.

database name: liveedit

username: admin
password: admin

For those with errors on line 283/284, you need to select a date range first.
Working fine here, with the exception of a few typo's which had to be changed to reflect the names in the corresponding tables.

Thank you

- in original code :

//Start session

- in login.php please edit like this
//Start session

you must place code on the top, cannot any space.

if you are able to click the row and able to create input, all you have to do is refresh the page. thats the only flaw of this inventory sys. :)

If you are having login error, you might want to check the index.php to login.php to db.php

check if all the code is connected to your database.

Hi Argie,

Just looked at the code and I liked it.
I head a bit of headwind working through all the errors but with 2 hours if coding, all is working properly (at least for me :) ).
The code is nice and easy to read/adjust, but if I may, I would like to make some suggestions:
- for the Notice error: 'undefined index id' that everyone is complaining there are two simple mechanisms to put in place to make sure it doesn't show in the browser:
1. In index.php put the following lines:
echo '<ul>';
echo '<li>'." Registration Success You can now login ".'</li>';
echo '</ul>';
Normally this would not show if the error reporting level is set to low, so ...

2. Instruct users to set a lower error logging level like E_STRICT or E_ERROR or to exclude notice with ~E_NOTICE.

I would not suggest method 2 especially when you are in development mode :).

- mysql statement is deprecated in MySQL 5 so my suggestion is to use mysqli statements instead. This worked for me.

All in all, good code and really good effort. Keep on coding.
