I've loaded various thoughts I've collected into mysql. I want to write an
app, all in one file, that has the following features:
1. On initial entry, selects and displays the thoughts ( might add
pagination later - there aren't alot of records, for now.)
2. This main page includes separate forms near the top with submit buttons
to search, add a thought, view all thoughts, etc. The action for each form
is to call this same page. The submit buttons and thoughts are printed from
a function.
3. In the main logic, I am trying to do a $_POST and if isset() on each
submit button name and then call a corresponding function, do whatever it
has to do, unset the form variable and continue back to the main display.
The problem is that it's not calling any functions. The error log says that
the name of each submit button in my $_POST[] statements in the main logic
is an undefined index. I presume that they are undefined in the main logic
because the forms were defined in a function.
Is there anyway to access, in the same page, form variables that were
declared in a function on that page?
Thanks!

Barring typos I think this illustrates what you want to do:
myscript.php:
<?php
if (isset($_POST['submit'))
{
$whichbutton = $_POST['submit'];
$somefieldvalue = $_POST['somefield'];
if ($whichbutton == 'Red')
// do red things
if ($whichbutton == 'Blue')
// do blue things
}
else
{
$whichbutton = 'None';
$somefieldvalue = 'Starting value';
}
?>
<HTML> ....
<p>The last button pushed was <? echo $whichbutton; ?></p>
<form action="myscrip t.php" method=post>
<input type=text name=somefield value="<? echo $somefieldvalue ; ?>">
....
<input type=submit name=submit value="Red">
<input type=submit name=submit value="Blue">
</form>
....

This may not be a big deal, but I'm just kinda curious. If I have a
page that submits a form to itself, when is it better to assign each
element in $_POST to a variable to use for the rest of the page?
My situation probably doesn't make a difference, but say I have about
10 form fields, and when the page is posted back to itself, i call
each of those form fields 2 times (1 for error checking, 1 for SQL
insert, or to pre-fill form).

I was trying to troubleshoot a login page that doesn't work - it keeps

peculiar behavior.
register_globals is off, so at the top of my script I assign a few

$login = clean($_POST, 30);

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
