Value of $_POST variable is null, but shouldn't be.

hi everyone,
[code=php]
<?php
$CompanyName=$_ POST['CompanyName'];
echo $CompanyName;
?>[/code]

I have been using this code to get values from forms.It was working fine.But lately it is not getting what has been entered in the field named CompanyName.
It displays nothing.

can u write down the form code?

Changed thread topic to better match contents.

Is your form using POST or GET to send its contents? Try checking for:

[CODE=PHP]
echo "Get: $_GET[CompanyName]<br />";
[/CODE]

I have tried both GET as well as POST method in my form.In both cases, it displayed nothing.The same code is working fine on my friends computer.But doesnt work on my computer.

Hm. Couple of things I would try.

First thing, I would set error_reporting to E_ALL:
[code=php]
error_reporting (E_ALL);
[/code]

This will display NOTICE and STRICT errors that are normally turned off by default.

Also, try this:
[code=php]
print_r($GLOBAL S);
// Or...
print('<pre>' . print_r($GLOBAL S, true) . '</pre>');
[/code]

This will output your entire $GLOBALS array, which includes $_GET, $_POST, etc. If your input made it to your script, it'll be in here somewhere.

If not, take a look at this thread.

Getting an error when logging in

Parse error: parse error, unexpected T_STRING in /home/content/a/z/r/azreff/html/login.php on line 18


//Connect to database

mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error() );
mysql_select_db ($dbname) or die(mysql_error ());

session_start() ;
$username = $_POST['username'];
$password = md5($_POST['password']);
$query = “select * from users where username=’$user name’ and password=’$pass word’”;

$result = mysql_query($qu ery);

if (mysql_num_rows ($result) != 1) {
$error = “Bad Login”;
include “login.html”;

} else {
$_SESSION[‘username’] = “$username”;
include “memberspage.ph p”;
}

?>

As per your suggestion,I did error_reporting (E_ALL); and print_r($GLOBAL S),
the array displayed the values passed on by the form.
But it displayed warning:Undefin ed variable: _REQUEST and Use of undefined constant .
