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

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.

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.

Submitted byAnonymous (not verified)on Sat, 01/05/2013 - 14:52

change updateproduct.php file to:

//mysql_query("UPDATE inventory SET qtyleft='$itemnumber'
//WHERE id='$proid'");

$result = mysql_query("SELECT * FROM inventory
WHERE id='$proid'") or die(mysql_error());

$row = mysql_fetch_array( $result );

$count = $row['qtyleft'] + $itemnumber;

$result = mysql_query("UPDATE inventory SET qtyleft='$count' WHERE id='$proid'")
or die(mysql_error());

header("location: tableedit.php#page=addproitem");

something wrong with your database when i import it on mysql

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.

Submitted byanonymouson Fri, 06/07/2013 - 07:38

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:

USE `liveedit`;

and change the user and password in db.php.

Submitted byAnonymous (not verified)on Sun, 07/14/2013 - 22:20

Good Day, I have downloaded this file but it seems every time I log in it says Opps some thing went wrong.

It also has a notice:

Notice: Undefined index: id in C:\xampp\htdocs\inventory\index.php on line 49

What does it mean? How do I get the program running? Please help, I want to learn more about making an inventory system using php/mysql :3

I'm a junior IT student and I'm also working on my own inventory system. I need to research more design and layouts. Thanks! :)

Error: Opps some thing went wrong


--Original Code--
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "liveedit";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password)
or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Opps some thing went wrong");

--My changes--

$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "inventory"; //chaange this name of datbase name
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password)
or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Opps some thing went wrong");

I hope it will help to you guys.

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.
