Select Menu

[Anon]

I use a javascript select menu in my php main_menu program, which will load the selected page straight from the select menu with no submit button. (that part works)

Now I want to add a submit button to do the same job if the javascript is turned off.

When I try to call selected pages with Header("Location: ..../...") it gives me a warning when I press submit button saying "I can't use Header after having produced the output.....".

Can some one please tell me if there's any other way to do this

Show us the code where you use header.
I hope that you have this in a seperate page, other than the one that was JavaScript dependent.

The error means that you have sent something to the browser before header is being used.

Hi Peter

It's something like this...

javascript function "GoPage()" at the top
(this function loads the selected page)

then in the main part of the program you get the select menu with....
echo "<select name='selector' onchange='GoPage()' onblur='return options[0].selected = true'> \n";

just after

echo "</select> \n";

I have defined the submit button with name= 'submit'

and then....
if($submit)
{
Header("Location: ./$selector");

}

NO!
Can't do it like that.
It should be something like this:

page1.php #############
H T M L
<form action=page2.php>
<select name=url>
<option value="page56.html">Page 56
<option value="page45.html">Page 45
</select>
<input type=submit>
</form>
H T M L

page2.php ############
<? header("location: $url"); ?>

So page2.php should only have ONE single line.

Good luck!
