LifeDrop - Blood Donor Directory & Request Portal

LifeDrop is a blood donor directory PHP project with source code. Voluntary donors register with their blood group, city and last donation date, and hospitals or blood banks search for donors and post blood requests. The portal checks eligibility every day: men can donate again after 90 days and women after 120 days, with age 18 to 65 and weight 45 kg or more. Only eligible donors appear in search, so hospitals stop wasting calls on people who cannot give.

How it works

• Donor registers with blood group, gender, date of birth, weight, city and last donation date
• Each donor sees a blood drop gauge that fills day by day, with days left and the next eligible date
• Hospital posts a blood request (group, units, urgency, needed-by date) and all eligible donors of the city with a compatible group get a notification
• Donor clicks "I Can Donate"; only then the hospital can see the donor's mobile number
• Hospital confirms the visit and clicks "Mark Donated" - the donation is saved with a certificate number, the donor's last donation becomes today and the unit is added to the request
• Donor prints a certificate with QR code; anyone can verify it on the website
• Request becomes Fulfilled when all units are collected

Frequently asked questions

Does it need internet? No. Bootstrap, icons, fonts and charts are inside the project, so it runs fully on XAMPP.

Is there any payment? No. Blood donation is free, so the project has no payment module.

Can the 90 / 120 day rule be changed? Yes. The admin can change the gap, age limits and minimum weight on the Eligibility Rules page.

Is it suitable for 3 students? Yes. The README and explanation PDF split the work into three parts for three demos.
