Bug #10043 action handler not working

Seems as though the action handler doesn't work.  PHP page is coded as its won form handler.  Hitting "submit" simply reloads page with all the form variables not set.

No errors either... I tried on Apache 1.3.x / IIS4.0 both CGI and ISAPI.


<?
if ($submit=='')  {
   echo <<<EOT
<html><head><link rel="stylesheet" type="text/css" href="cbox-exp.css"></head>
<FORM method=post action=cutsheet.php>

...snip...

<BUTTON type="submit" NAME="submit" value="submit">Submit</BUTTON></FORM>
</body>
</html>

EOT;
}
else  {
  #begin form handler...
  echo "Made it!";
}
?>

What happens if you test $HTTP_POST_VARS['submit'] instead of  just $submit? Sounds to me like you don't have register_globals turned on in php.ini. Can you check that (also, make sure your test isn't happening inside any function) and post your results back here? 

Thanks,

Torben

I'm aware of the registerglobals.  No, no functions in my code.  It's relatively straihgtforward, actually.

<?
if ($submit=='')  {
echo <<<EOT
<html><head><link rel="stylesheet" type="text/css" href="cbox-exp.css"></head>
<FORM method=post action=cutsheet.php >
...snip...
<BUTTON type="submit" NAME="submit" value="submit">Submit</BUTTON></FORM>
</body>
</html>
EOT;
}
else {
#
# start!
#
...snip...
}
?>


Here's the top snip of my php.ini:

[PHP]

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior.  In order for PHP to
; read it, it must be named 'php.ini'.  PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory.  The
; path in which the php.ini file is looked for can be overriden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple.  Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; |				bitwise OR
; &				bitwise AND
; ~				bitwise NOT
; !				boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
;   foo =			; sets foo to an empty string
;	foo = none		; sets foo to an empty string
;	foo = "none"	; sets foo to the string 'none'
;
; If you use constants in your value, and these constants belong to a dynamically
; loaded extension (either a PHP extension or a Zend extension), you may only
; use these constants *after* the line that loads the extension.
;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).


;;;;;;;;;;;;;;;;;;;;
; Language Options ;
;;;;;;;;;;;;;;;;;;;;

engine			=	On	; Enable the PHP scripting language engine under Apache
short_open_tag	=	On	; allow the <? tag.  otherwise, only <?php and <script> tags are recognized.
asp_tags		=	Off ; allow ASP-style <% %> tags
precision		=	14	; number of significant digits displayed in floating point numbers
y2k_compliance	=	Off	; whether to be year 2000 compliant (will cause problems with non y2k compliant browsers)
output_buffering	= Off	; Output buffering allows you to send header lines (including cookies)
							; even after you send body content, in the price of slowing PHP's
							; output layer a bit.
							; You can enable output buffering by in runtime by calling the output
							; buffering functions, or enable output buffering for all files
							; by setting this directive to On.
output_handler		=		; You can redirect all of the output of your scripts to a function,
							; that can be responsible to process or log it.  For example,
							; if you set the output_handler to "ob_gzhandler", than output
							; will be transparently compressed for browsers that support gzip or
							; deflate encoding.  Setting an output handler automatically turns on
							; output buffering.
implicit_flush		= Off	; Implicit flush tells PHP to tell the output layer to flush itself
							; automatically after every output block.  This is equivalent to
							; calling the PHP function flush() after each and every call to print()
							; or echo() and each and every HTML block.
							; Turning this option on has serious performance implications, and
							; is generally recommended for debugging purposes only.
allow_call_time_pass_reference	= On	; whether to enable the ability to force arguments to be 
										; passed by reference at function-call time.  This method
										; is deprecated, and is likely to be unsupported in future
										; versions of PHP/Zend.  The encouraged method of specifying
										; which arguments should be passed by reference is in the
										; function declaration.  You're encouraged to try and
										; turn this option Off, and make sure your scripts work
										; properly with it, to ensure they will work with future
										; versions of the language (you will receive a warning
										; each time you use this feature, and the argument will
										; be passed by value instead of by reference).

													; Note:  If this directive is empty, PHP

													; variable!
safe_mode_protected_env_vars = LD_LIBRARY_PATH		; This directive contains a comma-

Does this happen with latest CVS snapshot:
