Hi Mario,
you can set error_reporting to E_ALL to give you more hints to
bugs and to produce clean code.
You are having two problems. The first was related to your form
and has been addressed by Yasin.
The second is that you have autoglobals off. That means you have
to use $_SERVER['PHP_SELF']. BTW: You could have found this
error by reading about predefined variables, PHP_SELF in the
manual.

RE: [PHP] dropdown Newbie question
Hi there.
The value from that dropdown will be returned to you in the variable
$_POST OR $_GET, depending on which method you used to submit the form.
Assuming you use POST, you can access the selected value like this:
$var_from_dropdown = $_POST['theme'];

Hey,
If your php version is = 4.1.0 use:
$var_from_dropdown = $_GET['theme'];
else use:
$var_from_dropdown = $HTTP_GET_VARS['theme'];
You might want to change the method used to submit your form
from get to post, like:
// Start Dropdown
echo 'form name=theme action=options.php method=post target=right
class=menu
Then you code should read: $var_from_dropdown = $_POST['theme']; or
$var_from_dropdown = $HTTP_POST_VARS['theme']; applying the rules from above.
Hope that helps!

You need to place METHOD=POST in the original form tag and remove it from
the submit tag. Try that

Well, this is my original Code:

// Theme
echo '
form name=theme action=options.php target=right class=menu
METHOD=POST
nbsp;nbsp;select name=theme';
for($i=0;$isizeof($theme_name);$i++)

}
echo '/selectnbsp;nbsp;input type=submit name=get value=select';
$var_from_dropdown = $_POST['theme'];
exec(echo $var_from_dropdown /tmp/varfromdropdown);
The file /tmp/varfromdropdown is still emty. (the dropdown field is NOT emty
by
the time i press the select button)
Any other ideas?

Re: [PHP] dropdown Newbie question
Why don't you take the guesswork out of it a bit, and NOT write to a file
just yet... instead, just echo the var to the screen. IF that works, then
we know it's not your form that is the problem, it's the exec().
