  1. im not at coding sir… whats this?

    Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in C:\xampp\htdocs\GCCentrum\include\function.php on line 37

  2. how can I “unlock” remove function?
    I could add new employee/customer/product … etc. but in “action” column there is no “remove” button. only “Details” and “Edit” can be selected.

    Thank you

    • Good day sir, If you’re looking for the password that has been set in this post you have to use mysql for that. and to add users to you can either run the system and add user in it by using the admin account or you can use mysql to insert a query. And last, for decrypting I used Sha1 for that which you can’t decrypt it unless you’re going to change the encryption. I hope it helps.

    • in case of localhost XAMMP:
      1. First download zip file. 2.Unzip file. 3. create folder inside htdocs like ‘abc’. 4. Put all unziped files/folders inside abc folder. 5. create databse named prince through phpMyadmin. 6. open prince.sql file using notepad and copy all then past in in sql tab of phpMyadmin then click go and wait for creation all tables. After success message go to browser and type ‘localhost/abc’
      7. You are done.
