Hi,

I am developing an application using PHP. My application have some pdf file which user can download after registration. But, these pdf files will have 2 months of validation i.e. PDF file would be expired after 2 months from the date of registration, How can I set dynamic expiry date in PDF javascript? Do you provide any plugin or something like that? Please help ASAP.

Thanks
