I currently have been trying to learn PHP (as Apache module) and it doesn't
work. Through Apache I get this error:
"[Tue Feb 19 18:41:11 2002] [error] PHP Warning: Undefined variable:
username in ...filepath...\apache group\apache\htdocs\second.php on line 13"
The book I'm using to program with PHP says that by creating a NAME value
for a FORM gives me a variable with that name (and '$' included infront of
it). However, it doesn't seem to work that way:
Apache version: 1.3.23
PHP version: 4.1.1
OS: Windows XP
I think Windows XP and Apache are the problem because on their site they
have listed this warning for XP:
"If you will install Apache on Windows XP, be warned. There is a known bug
our users have identified; you may or may not encounter it yourself. It will
be fixed in the forthcoming Apache 1.3.24 release. The effects of this bug
within Apache 2.0 Beta are not yet determined.
It appears the combination of duplicating file handles between and parent
and child process, in conjunction with blocking sends to the http client,
may result in corrupted output. You may not see this in MSIE, which tends to
throw any error in the 'Cannot find server or DNS Error' category.
If you receive such errors on Windows XP using SSI scripting or PHP scripts,
but not static pages, you are probably a victim of this bug. It has been
reported to Microsoft, we have no further details at this time."
The thing is though, the bug is kind of a strange one... not creating the
variable. Is that the result of Apache and XP or am I doing something
completely wrong (in the following code I also tried the echo function):
--------------------------------------------CODE----------------------------
---------------------------
<HTML>
<BODY>
<FORM>
Please type your name here:<BR>
<INPUT TYPE="text" NAME=username><BR><BR>
<INPUT TYPE="submit" VALUE="Submit">
</FORM>
<BR><BR>
You typed:
<?php
print($username);
?>
</BODY>
</HTML>

No offense, but you are doing something completely wrong. For starters,
your <form> has neither a method nor an action. Try this code, if you have
Apache and PHP installed correctly, it will work. Even on XP.

No offense taken, but I have never done this before so I don't really know
what I'm doing with the variable passing and stuff (aside from C++ and VB
knowledge). I copied that from the book exactly and it did not work.
Your form does not work either, it simply gives me the else statement's
actions ("No data yet, or $username is empty."). I do believe I hit the bug
they were talking about and am now thinking of getting Linux from my boss
too install and run for PHP. Thanks for the help.

Try this instead. I couldn't get Devon's to work on my system either, but
this one does. Note the use of the empty() function which tests a string
for emptiness.
Let me know if it works?

<?

echo "
<form method=post action=".$PHP_SELF.">
<input type=\"text\" name=\"username\"><br>
<input type=\"submit\" value=\"Post Data\">
</form><i>No data yet, or username is empty.</i>";
}
else
{
echo "<b>Username:</b> " . $username;
}
?>
</body>

This should also work;
-- snip --
<form action="<? echo $PHP_SELF; ?>" method="post">
Username: <input type="text" name="username"><br>
<input type="submit" value="Post Data">
</form>
<?
if ($username) {
echo "Username: ". $username ."<br>\n";
}
?>
-- snip --
