Question

嗨，我是php的新手可以请一些帮助。我正在创建一个网站，它有一个菜单，我需要它，以便如果点击像“link1”这样的链接，page1.php将加载到mainSection div中，如果点击了link2，则page2.php将加载到mainSection等中。所有页面：page1，page2，page3等将根据点击的链接加载到此单页中。这可能我不知道从哪里开始。感谢

    <body>
        <?php
            <ul>
                <li><a href="#" name="link1">link 1</a></li>
                <li><a href="#" name="link2">link 2</a></li>
                <li><a href="#" name="link3">link 3</a></li>
                <li><a href="#" name="link4">link 4</a></li>    
            </ul>
        ?>

       <div id="mainSection">
            <?php
        if (link1 == true){
             include 'page1.php';
        }
        if (link2 == true){
            include 'page2.php';
        }
        if (link3 == true){
            include 'page3.php';
        }
        if (link4 == true){
            include 'page4.php';
        }
            ?>  
        </div>
    </body>

Answer 1

这是你可以从

开始的

<body>
            <ul>
                <li><a href="?link=1" name="link1">link 1</a></li>
                <li><a href="?link=2" name="link2">link 2</a></li>
                <li><a href="?link=3" name="link3">link 3</a></li>
                <li><a href="?link=4" name="link4">link 4</a></li>    
            </ul>

       <div id="mainSection">
            <?php
        $link=$_GET['link'];
        if ($link == '1'){
             include 'page1.php';
        }
        if ($link == '2'){
            include 'page2.php';
        }
        if ($link == '3'){
            include 'page3.php';
        }
        if ($link == '4'){
            include 'page4.php';
        }
            ?>  
        </div>
    </body>

Answer 2

除了majid的代码，您还必须检查链接是否已设置，否则会引发未定义$ link的错误。

link 1
link 2
link 3
link 4

   <div id="mainSection">
        <?php
    if(isset($_GET['link'])){
    $link=$_GET['link'];
    if ($link == '1'){
         include 'page1.php';
    }
    if ($link == '2'){
        include 'page2.php';
    }
    if ($link == '3'){
        include 'page3.php';
    }
    if ($link == '4'){
        include 'page4.php';
    }
      }  ?>  
    </div>
</body>

Answer 3

将链接的格式更改为：

<a href="/?1" name="link1">link 1</a>...

然后将PHP更改为：

<?php
        if ($_SERVER['QUERY_STRING'] == 1){
             include 'page1.php';
        }
        if ($_SERVER['QUERY_STRING'] == 2){
            include 'page2.php';
        }
        if ($_SERVER['QUERY_STRING'] == 3){
            include 'page3.php';
        }
        if ($_SERVER['QUERY_STRING'] == 4){
            include 'page4.php';
        }
?>

php检查链接是否已被点击
