Join David Powers for an in-depth discussion in this video Solution: Plan the order form, part of PHP for Web Designers.
…The challenge was to devise a plan for handling the data submitted by the Build a…Bouquet page so that the details of the…order are displayed correctly in the order confirmation page.…This is the way it will work in the final version, so if I change Calla Lillies from…Blush to Purple, and add three of those, and let's have, say, three sunflowers.…And some gerberra daisies,…orange.…My color coordination may not be perfect, but never mind.…And then add to basket.…
And all that will be displayed here are those items that have been ordered.…The quantity, the cost, the shipping, and the total.…So that's the ultimate aim.…The first stage in dealing with any form is…to find out what sort of data it submits.…So let's go to our editing program.…There's bouqet.php and I've scrolled it down to the bottom.…There is the submit button.…The name of the submit button on line 247 is bouquet.…So, we can use that knowledge, to find out what…is being submitted, from the form when we go to order.php.…
So let's open that page.…An then above the doc type, will create a PHP block.…
