  3. Good day
    Say when an employee applies for a leave and the leave has to be approved by the HOD and the Administrator how does one goes with that.
    Also if an employee has a number of days per annum and those days have to be deducted each time an employee takes leave how do you incorporate both of this scenarios.

    Thank you

    1. The administrator can only manage leave requests from employees. On the other side, that particular feature is not available in this project where each employee has certain leave days per annum.
      The one you’re looking for is available on another project named “Leave Management System in PHP”

  4. I cant login on employees panel. Passwords not working. What are the sample passwords for the given mail?

        1. the given login details are for the admin panel. the one you see first; the email address is for employee login. first login as admin, create an employee then you’ll receive employee login details. for more: please check the demo video!

  5. Hello,
    Got the following error when trying to open the project :
    Fatal error: Uncaught Error: Call to undefined function mysql_connect() in C:………………

    Need assistance on this.

      1. That’s due to your LATEST version of PHP. This project was only tested with PHP 5.6 and 7.4 (as mentioned in the project overview table and text files)

    is there a posibility that the system can send an email to the admins address or any specified address when someone applies for leave so that the admin does not have to login every few minutes to see if someone has applied

    great project by the way

    kind regards

    1. There were possibilities via Gmail SMTP, but now [from May 30, 2022] Google no longer supports the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password.

      1. can you possibly advise if we can input our own smtp server details the mail must send from

        and in what php file can the details be edited in , i would really appreciate the help

        thanks in advance

          1. understandable

            is there a possibility anyone can assist with the request or can you reccomend anyone who will be able to assist

            it would be much appreciated

    1. Nope, we haven’t changed any. Just don’t enter the admin login details at Employee Login Panel! There’s a different Admin Login Panel for that! Also, watch the full video in order to understand the working flow of the system.

  9. hello,

    noticed that employee can book holidays with wrong dates.

      1. yes i put my projrct name there, that’s just an example. but what I entered is the name I have downloaded from unzipping the file

          1. it’s not just the files I downloaded from this web. the project I created myself is so, is it a problem from my pc or how?

          2. It looks like a problem with your device. Also, if your localhost server has other port number defined except 8080[default ones], then you have to enter the URL like localhost:[PORT_NUMBER]/[PROJECT_FOLDER_NAME]

  10. Good day
