Ames Posted February 27, 2009 Share Posted February 27, 2009 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 ???

samshel Posted February 27, 2009 Share Posted February 27, 2009 Try Java script...PHP is server side.. if u already have all the information u need in ur page (Quantity & Cost), u dont need to go to server to calculate something... Use Javascript to do that. Link to comment https://forums.phpfreaks.com/topic/147215-solved-automatic-calculations/#findComment-772824 Share on other sites More sharing options...
