[SOLVED] Automatic Calculations ?!?!

Recommended Posts

Hey all,

 

What I want to do might not even be possible, but I'm sure somewhere I've seen it done.

 

I have a table with 4 columns TYPE / QUANTITY / PRICE / COST

 

The quantity is a textbox so the user can enter a number & the price is stored in the database.

Is there a way so that the user can enter the quantity (which will be multiplied by the cost) & the cost will automatically be displayed / calculated without any submit buttons.

EG the user enters 5 & finds out it'stoo expensive, so deletes the number & types in 2, the cost will change immediately.

 

I'm probably barking up the wrong tree here, I've looked everywhere I can think of. It might not be doable with php, any help or advice is very much appreciated.

 

Thanks      ???
