PHP的包括內容不加載，可能哈希標籤/地址發行

Question

我試圖得到上面的腳本工作，但也有一些變化。我需要的內容加載爲PHP包括，而不是一個HTML字符串。我現在的主要問題是，我不認爲代碼是指向正確的頁面，因此沒有新的內容。

PHP：

switch($_GET['page']) { 
    case 'code' : $page = include ($_SERVER['DOCUMENT_ROOT'].'mysite/code.php'); break; 
    case 'design' : $page = include ($_SERVER['DOCUMENT_ROOT'].'mysite/design.php'); break; 
    case 'writing' : $page = include ($_SERVER['DOCUMENT_ROOT'].'mysite/writing.php'); break; 

HTML：

<ul id="menu"> 
     <li><a title="index" href="#index.php" rel="ajax"><span>home</span></a></li> 
     <li><a title="code" href="#code.php" rel="ajax"><span>code</span></a></li> 
     <li><a title="design" href="#design.php" rel="ajax"><span>design</span></a></li> 
     <li><a title="illustration" href="#illustration.php" rel="ajax"><span>illustration</span></a></li> 
     <li><a title="writing" href="#writing.php" rel="ajax"><span>writing</span></a></li> 
     <li><a title="links" href="#links.php" rel="ajax"><span>links</span></a></li> 
     <li><a title="about" href="#about.php" rel="ajax"><span>about</span></a></li> 
     </ul> 

的javascript：

<script type="text/javascript"> 

    $(document).ready(function() { 

    //Check if url hash value exists (for bookmark) 
    $.history.init(pageload); 

    //highlight the selected link 
    $('a[href=' + document.location.hash + ']').addClass('selected'); 

    //Seearch for link with REL set to ajax 
    $('a[rel=ajax]').click(function() { 

     //grab the full url 
     var hash = this.href; 

     //remove the # value 
     hash = hash.replace(/^.*#/, ''); 

     //for back button 
     $.history.load(hash); 

     //clear the selected class and add the class class to the selected link 
     $('a[rel=ajax]').removeClass('selected'); 
     $(this).addClass('selected'); 

     //hide the content and show the progress bar 
     $('#content').hide(); 
     $('#loading').show(); 

     //run the ajax 
     getPage(); 

     //cancel the anchor tag behaviour 
     return false; 
    }); 
}); 


function pageload(hash) { 
    //if hash value exists, run the ajax 
    if (hash) getPage();  
} 

function getPage() { 

    //generate the parameter for the php script 
    var data = 'page=' + document.location.hash.replace(/^.*#/, ''); 
    $.ajax({ 
     url: "loader.php", 
     type: "GET",   
     data: data,  
     cache: false, 
     success: function (html) { 

      //hide the progress bar 
      $('#loading').hide(); 

      //add the content retrieved from ajax and put it in the #content div 
      $('#content').html(html); 

      //display the body with fadeIn transition 
      $('#content').fadeIn('slow');  
     }  
    }); 
} 

    </script>

你確定你找到了正確的道路？

case 'code' : $page = include($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mysite/code.php'); break; 
case 'design' : $page = include($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mysite/design.php'); break; 
case 'writing' : $page = include($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mysite/writing.php'); break; 

$ _ SERVER [ 'DOCUMENT_ROOT']在不同的環境中可能已斜線與否，從$ _SERVER [ 'DOCUMENT_ROOT']

case 'code' : $page = include ($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mysite/code.php'); break; 
case 'design' : $page = include ($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mysite/design.php'); break; 
case 'writing' : $page = include ($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mysite/writing.php'); break;

include不返回任何東西，但真/假指示包括成功/失敗。基本上它很像eval()，除了使用外部文件。如果您的網頁包含的實際產生輸出，你就必須先佔領：

ob_start(); 
include('somepage.php'); 
$content = ob_get_clean(); 

return $content; 

或者，如果包括正在生成的內容，並保存到一個變量，則：

include('somepage.php'); 
echo $whatever_var_that_somepage_php_stored_the_content_in;
