    php page will not process link to diff page

    Hello PHPers,
    I have just installed RH Linux ES 3.0 (basic) kernel 2.4.21-9.EL, i686,
    Apache 2.0.X, and php 4.2.X. I have made no changes to the php.ini.

    I am trying to use the following page (code listed here) to click on
    link, and display 1 of three pages. The code does not seem to work, it
    only shows the "else" condition of the php code, which is page:
    "stuff.php" . What do I need to do to my apache/php config to get this
    to work??? Of course I copied this code from a php site tutorial somewhere.

    Thanks,

    eric

    Page code below:
    <?
    if ($link == page2){
    $page="files/page2.html";
    }
    elseif($link == page3){
    $page="files/page3.html";
    }
    else{
    $page="files/stuff.php";
    }
    ?>
    <html>
    <head>
    <title> index.php </title>
    </head>
    <body bgcolor="#99999 9">
    <table width="100%" cellpadding="0" cellspacing="0" border="0">
    <tr>
    <td colspan="3"><h1 >The Template (index.html)</h1></td>
    </tr>
    <tr>
    <td align="center" valign="top"><a href="index.php ?link=index">
    Page 1 </a></td>
    <td align="center" valign="top"><a href="index.php ?link=page2">
    Page 2 </a></td>
    <td align="center" valign="top"><a href="index.php ?link=page3">
    Page 3 </a></td>
    </tr>
    </table>
    <? include($page); ?>
    </body>
    </html>

      Where does $link get its value? Unless there's some other code you didn't
      show that sets it, it's going to be NULL and therefore neither of the first
      two comparison will succeed. Also, page2 and page3 really need to be
      quoted in the comparisons.

          Hello and Thanks, I "thought" that $link gets set by clicking on the
          link on the index.php i.e. <href="index.ph p?link=page2"> Page 2 </a></td>
          here I thought the $link gets the value "page2"??? Obviously I am
          missing somthing (total beginner here!)
          It is not clear to me how $link can get set.

          Thanks for your help,
          eric

              You should add this line to the top of the page (after the <?php) if you
              want $link to contain the variable 'link' from the querystring:

              $link = $_GET['link'];

              You should also add single quotes ( ' ) around page2 and page3 in your
              if statement.
