How to Build responsive forms?

Permalink
I'm looking to build a page which calculates building materials.

a person could enter
# of solid panels
# of window panels
# of door panels

And see an out put of the total number of 2x4, sheets of ply wood.. as well as cost.
Either live as you'd see in excel. Or maybe a click submit and see results?

Any add-on out there for this?

Thanks

I don't know of any add-ons, but if you are not trying to save the information to the database you could use an External Form (http://www.concrete5.org/documentation/editors-guide/in-page-editing/block-areas/add-block/external-form/) to post to a single page with a PHP script to do your calculations.

Agh that would involve a lot of reading on how to do forms.

I wonder if there's something to convert excel to php heh.

Thanks. will look into it.

If PHP isn't your forté, maybe jQuery/Javascript would be easier? A quick Googling found this jQuery calculation plugin that can do math on fields on a page:

If you scroll down the page a bit, they have an example of an order form layout... when the quantity changes, the line-totals and grand-total re-calculate automatically.

Worth a look!

Thats actually pretty close to my needs.
I'm just really new to the material. would take some serious time to get it worked out.

My php doesnt suck.. but..

<?php
$sw = 2; 
$ww = 2;
$dw = 2;
$stud = 1.50; 
$t24 = 2;
$824 = 2.5;
$sheets = 7;
$req_studs = ($sw * 3) + ($ww * 4) + ($dw * 5);
$req_t24 = ($sw + $ww + $dw) * .5;
$req_824 = ($sw + $ww + $dw) * .5;
$req_sheets = ($sw + $ww + $dw);
$cost_total = ($req_studs * $stud) + ($req_t24 * $t24) + ($req_824 * $824) + ($req_sheets * $sheets);
?>
<table border="1" width="34%">
Viewing 15 lines of 40 lines. View entire code block.

I get an error on line 7 I believe
