Hello
Mignon,
this is really a php-generals question me thinks (you don't even mention a DB ;-),
regardless....
I need to dev a small app and I can think of a couple different ways to handle it but not sure the best way. I need to register those who come to our site that want to download .pdf's. They will fill out some information before I redirect to the pdf.
I'm thinking the best way to handle this is sessions, but is it appropriate to store all of the users info - so that if he downloads 2 items - I can re-populate the fields so he doesnt have to? So if they click on an additional pdf I'll need to somehow check for the session and re-populate 11 fields, and they will only have to fill in one field at that time.
Or would cookies be better ? I need to store probably 11 different form variables. Also - would you store the variables in an array in the session? This seems neat and tidy...
lets see:
if you put the data in a cookie then you are allowing malicious users to change that data
after you have stored it (so you will have to check it _everytime_ you want to use it)...
best to stick an array in the $_SESSION array.. that way you oly need you sanitize the
data when you add/change it - there is no problem with storing an array with 11 items it in in the
session, and using an array rather than 'loose' variables would definitely be neater -
you have all the user/pdf data in on place and its easy to extend that ammount of
info you store (i.e. if your client decides users must fill out more information to download a pdf)
Hope this is clear.
Any advice/guidance/sample scripts would be appreciated.
Thanks
