如果else语句显示为两个字符串:[关闭]

Edit three - In which we find out I am really not very clever

False alarm people, I can't use php in my current setup. I will go beat my head against a wall for a while. Thanks for your help and suggestions anyway.


I am attempting to follow this tutorial in order to allow a "Mobile/Full" switch on my responsive website. However, the link being used to display the option is showing both at once, not an 'either or' situation like it's supposed to.

The tutorial is using a little bit of PHP, which I don't know yet, so I don't know exactly where the error is. It all looks fine to me, but this code:

<div id="toggleView">
<?php if ( $fixedwidth == '1' ): ?>
        <a href="<?php echo $_SERVER["SCRIPT_NAME"] ?>?fixedwidth=0">Switch to Mobile site</a>
<?php else: ?>
        <a href="<?php echo $_SERVER["SCRIPT_NAME"] ?>?fixedwidth=1">Switch to Full site</a>
<?php endif; ?>
    </div>

Should display only one of the strings, but instead it displays both links like this:

?fixedwidth=0">Switch to Mobile site ?fixedwidth=1">Switch to Full site

I'm thinking it's a syntax problem with the ["Script_Name"] segment but I don't know what the correct syntax should be.

EDIT

This is the PHP I've inserted on my page to detect the change in fixedwidth:

<?php
    $fixedwidth = '';
    // Check if the query string contains our key and assign its value to $fixedwidth
    if ( isset($_GET['fixedwidth']) && ($_GET['fixedwidth'] != "") ) {
        $fixedwidth = $_GET['fixedwidth'];
    }
    // Check if a cookie has already been set
    if ( isset($_COOKIE['fixedwidth']) ) {
        if ( $fixedwidth == '0' ) {
            // If the value is '0', delete the cookie
            setcookie('fixedwidth', '', time() - 60, '/');
        } else {
            // Value is not '0', so no need to get the cookie value
            $fixedwidth = '1';
        }
    } else if ( $fixedwidth == '1') {
        // The user wants fixed width, so set a cookie
        $expires = 60 * 60 * 24 * 60 + time(); 
        setcookie('fixedwidth', '1', $expires, '/');
    }
?>

So, I've basically copy-pasted this from the tutorial to try and get this functionality on my page but I don't know if it's actually correct.

Edit 2 - Electric Boogaloo

Here's the code from the page in question:

        $fixedwidth = $_GET['fixedwidth'];
    }
    // Check if a cookie has already been set
    if ( isset($_COOKIE['fixedwidth']) ) {
        if ( $fixedwidth == '0' ) {

    }
?>

    To make this a bonafide answer, from the comments and your edits it can be seen that you are attempting to write PHP code into an ASPX file who's language is set to C#, and that is why it does not work.

    You need to rewrite this using ASP.net's template syntax, not PHP.
