PHP code did not create a cookie and it did not changed the background and text color

Initially, the code load the page, and default the background and text color to white. I then select a different background and text color, and I clicked the submit button. The page refreshes but the background and text color was not changed, and it never created a cookie on my PC.

On IE 6.0, I set the cookies option to prompt
I selected Tools --> Internet Options --> Privacy -->
Advanced --> set the First-Party Cookies to prompt

=================================

Code:

<?PHP



if ($BeenSubmitted)

 {

  setcookie("BGColor", "$NewBGColor");

  setcookie("TextColor", "$NewTextColor");

  $BGColor = $NewBGColor;

  $TextColor = $NewTextColor;

 }

else

 {

  if (!$BGColor)

    $BGColor = "WHITE";



  if (!$TextColor)

    $TextColor = "BLACK";

 }

?>



<HEAD>

<TITLE>User Customization</TITLE>

</HEAD>





<?

  print ("<BODY BGCOLOR=$BGColor TEXT=$TextColor>\n");

?>





Currently your page looks like this!

<FORM ACTION="linh_cookies.php" METHOD=POST>



Select a new background color:

<SELECT NAME="NewBGColor">

  <OPTION VALUE=WHITE>WHITE</OPTION>

  <OPTION VALUE=BLACK>BLACK</OPTION>

  <OPTION VALUE=BLUE> BLUE </OPTION>

  <OPTION VALUE=RED>  RED  </OPTION>

  <OPTION VALUE=GREEN>GREEN</OPTION>

</SELECT>



Select a new text color:

<SELECT NAME="NewTextColor">

  <OPTION VALUE=WHITE> WHITE</OPTION>

  <OPTION VALUE=BLACK> BLACK</OPTION>

  <OPTION VALUE=BLUE>  BLUE </OPTION>

  <OPTION VALUE=RED>  RED  </OPTION>

  <OPTION VALUE=GREEN> GREEN</OPTION>

</SELECT>



<INPUT TYPE=HIDDEN NAME=BeenSubmitted VALUE=TRUE>

<INPUT TYPE=SUBMIT NAME="SUBMIT" VALUE="Submit!">



</FORM>

</BODY>

</HTML>

Use the global arrays to check for values instead.

These are $_POST, $_GET, $_REQUEST, $_SESSION, etc.

For example, to get the value from a post form use $_POST['NewBGColor']. ($_GET for get forms or just use $_REQUEST which checks them all).

Code:

if(isset($_POST['BeenSubmitted'])) {

  ...

  $BGColor = $_POST['NewBGColor'];

}

Yep the above code is correct :), well its'
the new feature they have added in php4 and above
you better check out the version of php you are using
and check out its' documentation.

Yeah, i should've mentioned that the original code is "correct", but some configurations (and new versions) of php don't automatically set the variables ($NewBGColor from $_POST['NewBGColor']) so it's best to use the new method instead. :)

Thank you everyone for your help.

The function setcookie("TextColor", "$NewTextColor"); did not put a cookie into my PC.

Is the statement with $_POST is from version 3 or version 4 ?
$BGColor = $_POST['NewBGColor'];

i think its' from version 4
thats' what i know :)
