Re: [mv] Slick little inventory checker (not!)

No problem, Barney.
On my results page and flypage, the code I posted sets the condition "are 
there any?".
So, the code on the results page would be something like:

[snip]

        [if explicit]
        [condition]
        return 1 if (('[item-field limited]' eq 'yes') && ('[item-data 
inventory qty]' < 1));
        return 0;
        [/condition]
         Item not available - We ran out!            
        [else]
         We have it!
        [/else]
        [/if]

[/snip]

You can print the quantity available; [item-data inventory qty]

As far as verifying that the customer doesn't order more than we have, I do 
that on the shopping cart page. I use perl to run through the cart and check 
quantities against the inventory database. Where an excess is ordered, I 
reduce the quantity to the maximum available. If there's a better way, I'm 
all ears!

Hope this helps,
Rob Maurer
