Unable to get variables from url

zoofy

I use Xitami www-server and PHP 4.2.3 with it.

I have problems getting variables from forms to work.

Here is a simple code that should work, but it always says "Write some text".

<?php
	if(! isset($write)){
		$message="Write some text";
	}
	else{
		$message="You Wrote $write";
	}
?>
<html>
<body>
<br>
<?php
	print("$message");
?>
<br>
<form action="form3.php" type="post">
	<input type="text" name=write>
	<input type="submit" Value="PUSH">
</form>
</body>
</html>

I can see that the url changes as it should when i use POST method. t is like this .../form3.php?write=Test. I have tried to use GET method but I got same results.

What should I do to get that to work. I haven't changed any php settings. The script works if I put it to my ISP:s webserver.

try using:

if (!isset($_POST[write])) {
  echo "..... diidnt work";
} else {
  echo "..... did work.. the value is : $_POST[write]";
}

and set the form method to post.

if this works then you need to edit your php.ini file if you want to access variables without doing this, chage register_globals to on.

OK .... it works now......ty

I chaned that "register_globals" to "On" and now it works.

I tried that $_POST[write] thing but it didnt work. It said error "undefined constant write - assumed 'write' " . I tried to put ' marks around write but it didn't work either.

I still have one question. I tried to use $PHP_SELF variable in action field but php doesnt recognize that variable.

How can I fit it?
