I am trying to make this work. Despite either submit button being pressed, both continue with the page its posted to, neither makes the page change??

The 1st Form - 2 Submit buttons. The code on the form is:

<input type="submit" value=" Place Order " name="B2" style="font-weight: 700"><input type="submit" value="Return to Menu" name="B1" style="font-weight: 700"></p>

The form it gets posted to has this in the very front:

if (isset($_POST['submit']) && $_POST['submit'] == 'Return to Menu') {
header('location: newmenu.php');
exit(); }

Can anyone see/tell me where it's going wrong. Many thanks

throw some debug output in there and see what's happening:
Code: 
echo "submit: " . $_POST['submit'];

if (isset($_POST['submit']) && $_POST['submit'] == 'Return to Menu') {
    header('location: newmenu.php');
    exit();
}

It's probably because you've named your submit buttons.

Because of that, you won't have an element of $_POST called 'submit'. You should, depending on which button is clicked, have a element named "B1" or "B2".

But test for yourself. Using the following:

[tt]test_doublesubmit.html[/tt]:
Code: 
<html><body><form method="post" action="show_post.php">
<input type="submit" value=" Place Order " name="B2" style="font-weight: 700">
<input type="submit" value="Return to Menu" name="B1" style="font-weight: 700">
</form></body></html>

[tt]show_post.php[/tt]:
Code: 
<?php
print '<html><body><pre>';

print_r ($_POST);

print '</pre></body></html>';
?>

play around and verify what is submitted.

sleipnir214,

multiple submit buttons with the same name should be ok, since only the button that is clicked transmits its name/value

Many thanks. The print_r ($_POST); reveals

[S1]=>
[B1]=> Return to Menu

So does that infer there is no Submit?

How does it get [S1]? Button names are B1 and B2?

ah - that's your problem right there - you've named them B1 and B2

this
if (isset($_POST['submit']) && $_POST['submit'] == 'Return to Menu') {
header('location: newmenu.php');
exit();
}

should be this
if (isset($_POST['B1']) && $_POST['B1'] == 'Return to Menu') {
header('location: newmenu.php');
exit();
}

but you could simplify to this since you only have one button named B1:
if (isset($_POST['B1'])) {
header('location: newmenu.php');
exit();
}

try { succeed(); } catch(E) { tryAgain(); } finally { rtfm(); }

That did it Jeff, thanks very much. Your print_r ($_POST);
produced submit on it's own.

Thank you all very much, I can pack it in for the night now knowing that one's dead and buried. I will remember the debug outputs next time. All have stars on me, thanks again.
