SESSION variable value is not passing
I'm trying to pass a value from a select input control on an HTML form. When I hardcode it, it gets echoed, when not, all I get is this: The invention type did not go through correctly.
Here is my page1.php:
<?php
se开发者_JAVA百科ssion_start();
$_SESSION['invtype'] = $invtype;
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
if (isset($_POST['Submit'])) {
if ($_POST['firstname'] != "") {
$_POST['firstname'] = filter_var($_POST['firstname'], FILTER_SANITIZE_STRING);
if ($_POST['firstname'] == "") {
$errors .= 'Please enter a valid first name.<br/><br/>';
}
} else {
$errors .= 'Please enter your first name.<br/>';
}
if ($_POST['lastname'] != "") {
$_POST['lastname'] = filter_var($_POST['lastname'], FILTER_SANITIZE_STRING);
if ($_POST['lastname'] == "") {
$errors .= 'Please enter a valid last name.<br/><br/>';
}
} else {
$errors .= 'Please enter your last name.<br/>';
}
if (!$errors) {header("location: offerform_switch.php");
}
else {
echo '<div style="color: red">' . $errors . '<br/>
</div>';
}
}
?>

</select>
<input type="submit" name="Submit" value="Next!" />
</div>
</div>
</body>
</html>
Here is my offerform_switch.php:
<?php
session_start();
// echo variable from the session, we set this on our other page
echo $_SESSION['invtype'];
$invtype = $_SESSION['invtype'];
//connect to your database ** EDIT REQUIRED HERE **
mysql_connect("mysql.myserver.com","myuser","mypassword"); //(host, username, password)
//specify database ** EDIT REQUIRED HERE **
mysql_select_db("invention") or die("Unable to select database"); //select which database we're using
switch ($invtype){
case "product":
include("page2_product.php");
break;
case "software":
include("page2_software.php");
break;
default:
echo "The invention type did not go through correctly.";
}
?>
What am I doing wrong?
Thank you!
It should be
$_SESSION['invtype'] = $_POST['invtype'];
You're missing "session_id();" right below the "session_start();". I don't know why exactly it's required, but if I remember correctly, it is.
