Dynamic Field

[rob294118]

Please let me know how I would do this and what Webassist tools I would use.

I'm trying to do the follow:

Merchant:

(drop-down list populated dynamic from a DB table)


Dollar Amount $:

(text field entered by user)


Redemption Value $:

(calculated field, based on a percentage value from a DB table for the selected merchant)

Rob,

you would need to use javascript to do this, I have set up an example using jQuery here (http://www.i-cre8.com/blog/tutorials/jquery/calculated-field/index.php) to show you how you could achieve this. Any questions please ask away but the code should be pretty self explanatory.

Thank you very much! This works great.

Do you know how I would allow a person to add multiple items like in this example:

[Dave Buchholz]

That's like a shopping cart system where each item is stored in an array, you could use eCart to do something like this if you wanted.

ok. thanks.

One more question. Do you know how to set up "Printing Labels" from the U.S. Post Office like ebay and Paypal let you do? I want the customer to be able to print a label from my site.

Rob,

sorry I have never had to implement something like that, I would assume that there is an API that you would hook into if you have an account with them but that is just a guess.
