MAMP PHP Mac OSX标头不起作用

Question

I've installed MAMP on a mac desktop running 10.6.8. I'm using dreamweaver as the IDE to develop my website. I have written my webpage in php, I can preview it in the browser and I can see eveything, so the server and that stuff works. But in my first page i have this line:

session_start();
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (!empty($_POST["Reg_type"])) {
        $_SESSION["regtype"]=$_POST["Reg_type"];
        header("Location: Page2.php");
        var_dump($_SERVER);
    }
}

So once the user selects a radio button from the form and clicks submit, it'll take them to the 2nd page. I know that it's going into the loop with the header but for some reason it is unable to redirect to page2. When I click an option and hit submit it just goes to page1 again. I think there might be a problem with the php.ini file dealing with header redirects of sessions, i have no idea. I am a newbie to macs. Does anyone know what the problem could be? Thank you

Answer 1

If Dreamweaver auto generated your code, check the line were the form tag is declared. If it looks like:

<form method="POST" action="">

then page1.php will reload, because it is calling itself. It would likely be cleaner to just change the form tag to

<form method="POST" action="page2.php"> 

and drop the whole if statement.

On submit page2.php will be loaded and that script/page will have $_POST['Reg_Type'] available for processing. Then if you need to assign $_POST['Reg_Type'] to a session variable, I would do it on page2.php.

And BTW, non of the above is exclusive to Mac.
