HawkCode Posted April 14, 2006 Share Posted April 14, 2006 Hi,I have a form I'm working on where I have a Quantity Field and there is a cost for each. If an Item is $25.00 and they enter 2 how can I update another field with the result (2*25)???Preferably the field updated should be read only.Thanks!Rich Link to comment https://forums.phpfreaks.com/topic/7436-dynamic-update/ Share on other sites More sharing options...

He has input boxes that is for a ordering system. He wants to add a Quantity box so the user can type in they want 2 of the $25.00 items. When the user's pushes the number key [i][b]" 2 "[/b][/i] he wants the Total Price to show $50.00.He wants real time multiplication of inputted values...I would assume this would need to be in JavaScript with using a [i]onBlur[/i] function or [i]onChange[/i] function. I am also asuming that by default the quantity is set to [b]1[/b]?Arif...you might want to post this in the JavaScript section of this forum & might get answered quicker: [a href=\"http://www.phpfreaks.com/forums/index.php?showforum=6\" target=\"_blank\"]http://www.phpfreaks.com/forums/index.php?showforum=6[/a] Link to comment https://forums.phpfreaks.com/topic/7436-dynamic-update/#findComment-27875 Share on other sites More sharing options...
inztinkt Posted April 18, 2006 Share Posted April 18, 2006 as stated above, this would require javascript. a script that would run onChange to check the contents of the selection and then perform an action with it and then release it to the read only text field.
