PHP and the "select" HTML value
Hey-yo! LOL, yet another PHP mishap has occured around me and the previously mentioned language...
I want to have the user choose a value from a "select" inside a form, and then based on that, they are redirected to somewhere else. But, it doesn't work. Here's the php:
<?php
$number=documents.forms[0].elements['kidsnum[]'];
if ($number==1) {
Header('Location: <a href="http://www.dscpool.com/signup1kid.html'" title="http://www.dscpool.com/signup1kid.html'">http://www.dscpool.com/signup1kid.html'</a>);
}
elseif ($number==2) {
Header('Location: <a href="http://www.dscpool.com/signup2kid.html'" title="http://www.dscpool.com/signup2kid.html'">http://www.dscpool.com/signup2kid.html'</a>);
}
elseif ($number==3) {
Header('Location: <a href="http://www.dscpool.com/signup3kid.html'" title="http://www.dscpool.com/signup3kid.html'">http://www.dscpool.com/signup3kid.html'</a>);
}
elseif ($number==4) {
Header('Location: <a href="http://www.dscpool.com/signup4kid.html'" title="http://www.dscpool.com/signup4kid.html'">http://www.dscpool.com/signup4kid.html'</a>);
}
elseif ($number==5) {
Header('Location: <a href="http://www.dscpool.com/signup5kid.html'" title="http://www.dscpool.com/signup5kid.html'">http://www.dscpool.com/signup5kid.html'</a>);
}
?>and my select is named 'name="kidsnum[]"' and id'ed 'id="kidsnum[]"'
any ideas? thanks.

PHP is server-side. If I didn't know any better, I'd say it can't pull form values using Javascript/DOM. You'll have to send the data via querystring using JS, or submit the form with either GET (querysting again) or POST. You could store the selected value in a cookie too, but that'd be a waste of a cookie -- one of the above would do.

What you can do is have two files containing the following code(s ):
index.html
URL1
URL2
URL3
request.php
<?phpheader("Location: $_POST['gotopage']);
?>
I haven't tried out this but it should work something like that anyway.
Good Luck

- you don't necessarily have to have two files. You can send the data to the same page, but invoke the redirect script with a flag of some sort.
- perhaps it'd be wiser to use GET in this case, as you may want the redirection to be accessed via a URL that can be copied.

Does this have to be done using PHP? Looks more like a job for JavaScript IMO

I was thinking Kyle had something more in mind with the PHP script. Yeah, if it's just a redirect, then JS could handle it. Unless you want to avoid depending on the client (JS disabled, etc).

You're right, you don't have to have two files. I just find it easier to use two files.

WOW...sorry i left out some info!
It's a form. I was using POST, and i did read on the php.net site that you can, http://www.php.net/manual/en/faq.html.php#faq.html.select-multiple
I just can't get it working. Any help via THIS part would be great. (I apologize for leaving out that info).

... is there a reason why you'd not use $_POST?
Your select form should be named "kidsnum" unless you enable multiple selections, and if you do that, I totally do not see how you'd do a mass redirect on that. You don't want to have people select more than one option, do you?
<?php
$number = $_POST['kidsnum'];
switch ($number) {
case '1':
header('Location: <a href="http://www.dscpool.com/signup1kid.html'" title="http://www.dscpool.com/signup1kid.html'">http://www.dscpool.com/signup1kid.html'</a>);
break;
case '2':
header('Location: <a href="http://www.dscpool.com/signup2kid.html'" title="http://www.dscpool.com/signup2kid.html'">http://www.dscpool.com/signup2kid.html'</a>);
break;
case '3':
header('Location: <a href="http://www.dscpool.com/signup3kid.html'" title="http://www.dscpool.com/signup3kid.html'">http://www.dscpool.com/signup3kid.html'</a>);
break;
case '4':
header('Location: <a href="http://www.dscpool.com/signup4kid.html'" title="http://www.dscpool.com/signup4kid.html'">http://www.dscpool.com/signup4kid.html'</a>);
break;
case '5':
header('Location: <a href="http://www.dscpool.com/signup5kid.html'" title="http://www.dscpool.com/signup5kid.html'">http://www.dscpool.com/signup5kid.html'</a>);
break;
default:
header('Location: <a href="http://www.dscpool.com/nosignup.html'" title="http://www.dscpool.com/nosignup.html'">http://www.dscpool.com/nosignup.html'</a>);
break;
}
?>

**note: it would be better to do a form that submits and gives the new form with the right amount of "kids" spaces than have five pages of options.

switch is shorthand, essentially -- it skips until it finds the right case, then does that, rather than stepping through each set of instructions until it gets the right one.

Fyi
variable = documents.forms[0].elements['var[]'];' from the link provided is for use with Javascript. Only client-side technologies and plugin-dependent scripts can access the Document Object Model (DOM) in that way.Renegade posted this at 22:50 — 21st September 2003.

Oh, sorry. I didn't read i guess. Thanks though.
no thanks, PHP is fine. it all works. (PHP is easier to understand for me...I'm trying to learn, so everything is in PHP when possible).
