Hiding / Showing form fields based on previous form input

[John Alexander Hopper]

Hello again

Another poser for you...

I've got a multi-page form, with the information from the previous page stored in hidden values, then everything is submitted on the final page.

Trouble is, certain fields are only applicable to either male or female members.

I'm using Dreamweaver 8, and I know how to show and hide information based on the arguments in Recordsets.

But, as the information from their signup (including their gender) is stored in hidden form fields - and not yet in the Database (where Recordsets look), how can I make a certain form question show up to only people who have given their gender as 'Female' on the previous page for example?

Many thanks in advance

John

If the variable is "hidden" it is still available. Just do an

PHP: Select all

if ($_POST['sex']=="female") {
    echo "Chicks rock!";
} else {
   echo "Dudez rule!";
} 

Or (for future reference) if the page is available both with and without a variable being passed,

PHP: Select all

if ($_POST['sex']=="female") {
    echo "Chicks rock!";
} elseif ($_POST['sex']=="male") 
   echo "Dudez rule!";
} else {
    echo "Long live sexual harmony!"
} 

You don't need to "hide" anything - you can just not write it; since you've harnassed the power of PHP, the page is generated and you can use any information passed to the page as a switch to generate or not generate output.

You could also set a cookie or a session variable if you want to use gender on a page where the POST variables haven't been passed.

And if you're learning PHP, maybe I can even convince you to kick off the Dreamweaver training wheels (unless of course it's a job requirement -- it's nice to know how to use it because some employers want it).
