Hey guys i need some help in completing a PHP school application that i am developing. Please i need gude on how to code an application like JAMB, WAEC in which student can register online to an application using a pin and serial number.

just like what is been done our examination body web sites.

I am developing one currently but using .Net
check it out on www.logiss.net.

Click on admissions. use 12345ABCDE as PIN.
Let me have ur feedback on david.adele@bluesten.com or 08035133522

Thanks

u cld create a database that wld contain registered pins. When som1 tries to log in, it checks if the pin is regisered and has not been used. U can get pin/password generation algorithm online to generate required pin.

I understand the logic behind it, But i need a sample code on PHP that will assit me in concluding the coding. I ave already started but was stuch in the middle.

i ve succeded in checking if pin exist in database or not but i want to still verify if that same card have been used by someone else or not before display the registration form

Here is my process

1 Check if pin is valid (exist in database or not)

2 If it does check if that pin is in use or not

3 else invalid pin

One a pin pass the two processes of verification (If pin exist in database and if pin is in use by another or no), registration form can now be displayed

I dnt use PHP So unfortunately, I cant give u a code sample. If i gt u ryt, the problem is knowin if the pin has already been used. U cld create a column, name it used and once som1 registers with the pin, it updates the pin row and sets d used column to true. Only pins with the used column not set to true can b used.

Hope dis algorithm wld help
Select used where pin = pin
if pin exists and used <> true
register
update used, set to true
else
invalid pin

Hope that has helped.

Thanks for that idea. Hey i dont mind if i ve some code sample in the language you are using. I can study codes and use the logic behind the idea to come up with a solution in the language i am use to.

I deeply appreciate your concern broda.

Best wishes to you

use vb.net. I browse majorly with my phone bt wld try to snd u sample code a.s.a.p

I've really busy, I could have taking tym to write it for you, pardon me, create a field in your database called usedpin having a default value 0, when a user registers,  set the usedpin=1, whenener
if (usedpin=1)
{
echo "Sorry this pin has been used";
}

If u are not in a hurry mail me.I will get done for u , oshadami_mj@yahoo.com

if you already have a code to check a column in the database, why not use same logic to check a different column ?
