View Full Version : PHP problems
putnamehere 10-09-2005, 02:21 PM Hey, i am creating a script that ask a user ther name and ther favorit color. it then echo the users name in ther favorit color, and it also saves a cookie for next time.
Heres the code that is used for them to submit ther data
<?php
$user = $_POST['user'];
$color = $_POST['color'];
$self = $_SERVER['PHP_SELF'];
if ( ( $user != null ) and ( $color != null ) )
{
setcookie ( "firstname", $user, time()+36000 );
setcookie ( "fontcolor", $color, time()+36000 );
header ("Location:getcookie.php" );
exit();
}
?>
and jsut below that php is this code, ( it's all one doc )
<html><head><title>ye<title></head><body>
<form action="<?php echo ( $self ); ?>" method="post">
Please enter your name
<input type="text" name="user"> <br><br>
Please select your color
<input type="radio" name="color" value ="#FF0000"> Red
<input type="radio" name="color" value ="#00FF00"> Green
<input type="radio" name="color" value ="#0000FF"> Blue
<br><br>
<input type="submit" value="submit">
</form>
</body>
</html>
The code in getcookie.php works fine the error message i am getting is,
Notice: Undefined index: user in C:\Abyss Web Server\htdocs\user.php on line 4
Notice: Undefined index: color in C:\Abyss Web Server\htdocs\user.php on line 5
Lines 4 & 5;
$user = $_POST['user'];
$color = $_POST['color'];
Witch is understable, as thers been no data submited so how do i get round this?
ps ( i want it as one file )
Douglas 10-09-2005, 04:06 PM here i fixed your code:
<?php
$user=$_POST['user'];
$color=$_POST['color'];
$self=$_SERVER['PHP_SELF'];
if ($user != null && $color != null) {
setcookie("firstname", $user, time()+36000, "/", ".YOURSITE.com");
setcookie("fontcolor", $color, time()+36000, "/", ".YOURSITE.com");
header("Location: getcookie.php");
exit;
}
?>
<html>

</head>
<body>
<?php
if (isset($_COOKIE['fontcolor'])) {
if (isset($_COOKIE['firstname'])) {
echo "Current Name/Color: <b>".$_COOKIE['firstname']."/".$_COOKIE['fontcolor']."</b><br />";
}
