Can different customers have different purchase page?

Hi
The Zen Cart realizes that different customers have different purchase pages after they log in.
Details:
1.I am doing the wholesale business and the number of my clients is limited. Actually, they usually buy the certain products every month.

2.I just want them to see the specific product they have ever purchased when they log in. For example, customer A usually purchase 100 "Toilet Papers" every month. I just want customer A to see the Toilet paper product on the site after A log in and customers A just needs to fill the quantity and go the check out part.

3.Possibly some customers purchased several products. After they log in, they can only see the products they have ever purchased.

Any idea?

The easiest way to do this is to simply turn on the order history sidebox.

However, that's not quite what you're asking about, since it wouldn't prevent customers from seeing things that they haven't brought from you before.

That said, that's almost certainly a good thing. If customers can only buy from you things that they've bought before, how will you deepen your relationship with them? And how would a first time customer buy anything? And how would you sell new products?

HI
Thanks for your reply. Actually what I ask above is just a part of my whole zen cart site function. Other pages such as new product , special and etc. can help me to deepen the relationship with my client.

So do you think it is possible to zen cart have the function to do it?
I have considered that I use the My Account part to do this function but that can only show what you have purchased and customers can not fill the quantity in My account.

what do you think? any idea?do I need to change the php code?

Thank

In that case, yes, this require significant custom programming in PHP.

I am not php expert but could you give me some tips? or some useful links so I can understand what should do.

Thanks
