variables not being passed

[robsgaming]

I cannot figure out why when submit is pressed, none of the variables are showing up, and a blank entry is being added to the database. please help if you get a chance, below is the code:

<?

mysql_select_db("gtjc",$db);
$query = "SELECT * FROM gtjc_mainpage ORDER BY timepost";
$result = MYSQL_QUERY($query);
$numfound = mysql_num_rows($result);

if($numfound > 0)
	{
		while ($row = mysql_fetch_array ($result))
			{ 
				extract($row);
				echo "$id, $subject, $publisher, $message, $timepost";
			}
	}
	else
	{
		echo 	"
			<BR><BR>
			<font class='text'>
			Nothing was found in the database.<P>
			<img src=\"$baseurl/images/dotbullet.gif\"><a href=\"$PHP_SELF?action=new\">Click here to add a record.</a>
			</font>
			<BR><BR>
			";
	}


if($action == "new")
	{
		if($submit)
			{
				echo "STUFF: $publisher, $subject, $message, $timepost";
				mysql_select_db("gtjc",$db);
				$query = "INSERT INTO gtjc_mainpage (subject,publisher,message,timepost) VALUES ('$subject','$publisher','$message','$timepost')";
				$result = MYSQL_QUERY($query);
				echo 	"
					<font class='text'>
					New one, it will be submitted.<P>
					<img src=\"$baseurl/images/dotbullet.gif\"><a href=\"$PHP_SELF\">Click here to go back.</a>
					";
			}
			else
			{

			echo	"
					<form method=\"post\" action=\"$PHP_SELF?action=new\">
					<table border=\"0\" width=\"400\" align=\"center\">
						<tr>
							<td width=\"100%\" bgcolor=\"#5E84C2\" align=\"center\">

							</td>
						</tr>
						<tr>
							<td width=\"100%\" align=\"center\">
								<input type=\"text\" size=\"30\" name=\"publisher\">

						</tr>
						<tr>

								<textarea name=\"message\" cols=\"45\" rows=\"20\"></textarea>
								<BR><BR>
								<input type=\"submit\" name=\"submit\" value=\"Submit Information\">
							</td>
						</tr>
					</table>
					</form>
				";

	}
}

nevermind.

after posting i just looked at how stupid i am. i was already extracting variables above, therefore already setting them. hehe, im dumb. thanks.

check you config in the php.ini
you should have the register global = off

this is more secure anyway don'T try to change it

simply use $_POST['var_name']

[robsgaming]

i have never understood $POST whatever or how to use it. can you please direct me to a tutorial or some information? thanks again.

http://www.php.net/manual/en/language.variables.predefined.php#language.variables.predefined

in some this is simple...
before version 4.3 the register global was on this meen in a form
when u use the method=post or method=get...

after the form submited you can access directly you var with $var
but now u must pass by $POST['var'] or $GET['var'] depend of your method use in the form definition
