Passing data from one script to the next

Anon

ok ok im really getting the hang of this php and database thing. now i need to know one last thing, ive got a database of dvd's that are for sale, ive got it setup to check and see if the inventory is available and if it is it sends you to the buy now page, what i want to know is, how do i send the info that was sent to the script that checked the inventory along to the buy-now page ? so i dont have to make a separate buy now page for each item ?

btw, when im all done with this, i will share with everybody how to make paypal, mysql and php all work togeher in perfect harmony 🙂 ive got it all figured out except a few minor details 🙂

Sessions would be the most secure way. You could also use hidden form fields to pass the info along.

I'd be very interested to hear how you have paypal working with everything. So , please do share.

ok so thats what i was thinking, but how does a hidden form pass the info if no submit button is pressed ?

my setup is like this:

add to cart button --> (php script: check database for availability) ---> if avaialble goto page that has a buy now button

i need to somehow get the product # from the add to cart's hidden form option into the page with the buy now button so i can use it to tell paypal which item to add to the cart. get it ?

this probably isnt the best way to do this, but hey it works 🙂

uhh.. all i wanna do is pass 1 varible between about 3 pages. thats it, nothing too fancy. can you help me ?

Yea... Do not give any output whatsoever to the screen (that means no tags or anything) register your session first then output and do varialbes etc... The session headers must be sent first. I thought it used to say something about that in the manual, but it looks like they just took that bit out.

Hope that helps!

You can use a get-redirect (ie:http://domain/page?sid=[session])
