[SOLVED] Automatic Expiry of the Code - PHP

[everurssantosh]

Hi,

 

I am trying to create an Authorization code for a user which should automaticaly get expired after 15 mins of generation.

 

I am using PHP rand function to generate the code. This code will be sent to user by mail. Now, user must use the code with in 15 mins in some other page.

 

The problem : how to I delete the code after 15 mins, though I save the time of generation of the code.

 

Please help me in this regard

If you're using a database you should set a creation time when you set the random number. Just check the creation time against the access time if it's been more than 15min then deny access, and delete the record.

if you save a timestamp with the code then when the user checks the code check the timestamp if after 15mins say invalid and delete it

Hi

 

Thank you for the reply...

 

But I dont want to keep the access code in database after 15 mins. I want to delete the access code after 15 mins... and the code will be generated again when the user requests for the code.

 

 

I am using PHP and MYSQL.. can I use triggers??? or anything in PHP??

 

Thanks

you could set a cron job to go every 15mins and check for old codes and delete them
