If you're really sure only one will be sent:

$type = $_POST['news'] . $_POST['dreams'] . $_POST['storys'] .
$_POST['words'] . $_POST['chat'];

will achieve what you're looking for.

The best solution would be to change this behavior, or at least add a
consistent form variable that you plan to receive.

What you need to do is name your variable 'type', so that $_POST['type'] is
either 'news', 'dreams', 'stories', 'words', or 'chat'.

Hope that helps.

As, in this case, only one of the variables is non-null, then you could use
the string concatenation operator and this would return what you want.

i.e. type = $_POST['news'] . $_POST['dreams'] . $_POST['storys']...

I think I've used the same variable name in different forms on the same page,
as only one form submission occurs at any one time there can't be a conflict
and PHP doesn't care where the POST'ed variable came from.. So, you could
rename news, dreams, etc. to be type and extract the result directly without
having to fiddle around.

Hello folks

I wrote a JavaScript to set the values of a Select html object by client
side. The values are copied from another Select that I create getting the
values from the database. After the user set the values he/she wants to add
it in another form, for example, then press submit button, the values of the
"user" Select object doesn't appears on the next page. What can I do to get
the user selected values in the another page?

Someone could help me?

Thanks!

Well, if I understand that correctly, you need to use Javascript to "select"
all of the options that the user selected to add to the second select box.
If they aren't selected, then they won't be passed to the next page.

Ok! Now I can see the values in the another page. But each value are passed
with the same name. How can I get all values using PHP script?

On the Address Bar I can see: index.php?slcAdd=1&slcAdd=2&slcAdd=3
But when I get the value using $HTTP_GET_VARS['slcAdd']; it returns just the
last value. What can I do to get them all?

Thanks!

Name your select box as "slcAdd[]" and you'll have all of the values in an
array.

Perfect! That's all I had to do.

Thanks!
