Well I got one line of code wrong in setcookie
I had
$color=$_POST['color']; should be
$bgcolor=$_POST['color'];
I did not need //echo "<form method=POST action='setcookie.php'>";
In cookie
I found the the GET works just fine I did change it to POST and this also worked
I played around with white space and found this to be a non issue as it is with most other languages that I have used. White space helps me to understand what is going on. So I need it.
I am a little confused by the fact that certain commands are placed first ie on line 1 eg a POST, but they seem to be executed last. I am more comfortable with a system that does command 1 and then 2 and then 3 etc.
Also in cookie there are in fact 2 POSTS one on line 1 or 2 and then on about line 20 (here i have a working GET) so this feels to me like I am sending the information twice. It also feels like the first POST should be the last line of code as the passing of data would be the last thing to happen before calling the next program.
A question:
can one do all of this in one program? We seem to be passing data from program to program in every task that we do, I do not always see why, it seems a bit odd?
my code is
cookie
<!--INSERT CODE HERE-->
<?php
echo "<form method=POST action='setcookie.php'>";
$background = $_COOKIE[background];
if ($background)
{
echo "<html>";
echo "<head><title>Selected Background Color</title></head>";
echo "<body bgcolor='$background' vlink='white'>";
echo "<a href='delete_cookie.php'>Delete Cookie</a>";
echo "</body>";
echo "</html>";
}
else
{
echo "<html>";
echo "<head><title>Select a Background Color</title></head>";
echo "<body>";
echo "<form method=GET action='setcookie.php'>";
echo "Select a background color";

}
?>
setcookie
<?php
//echo "<form method=POST action='setcookie.php'>"; This is not needed at all
$bgcolor=$_POST['color']; // I got this wrong it was $color=$_POST['color']
switch ($color) {
case "Yellow":
$bgcolor="#FFCC00";
break;
case "Blue":
$bgcolor="#4682B4";
break;
case "Silver":
$bgcolor="#C0C0C0";
break;
case "Beige":
$bgcolor="#FFE4C4";
break;
}
//INSERT CODE HERE TO SET THE COOKIE
setcookie("background", $bgcolor, time()+3600);
echo "<html>";
echo "<head><title>Selected Background Color</title></head>";
echo "<body bgcolor='$bgcolor'>";
echo "</body>";
echo "</html>";
?>
