Question

首先，我想说我是php新手。

我正在为虚构的音乐商店创建一个php网站。我创建了一个数据库，我已经使用php从数据库中将所有信息都插入到网站上。在我的项目中，我有三个链接，分别是“主页，关于我们，联系我们”。我已使用此代码在我的网站中插入这三个链接

<?php 
$id = $_GET["id"];
$query = mysql_query ("SELECT id,menu_title,target FROM menu_titles");
while($result = mysql_fetch_assoc($query)){
$id = $result["id"];
$title = $result["menu_title"];
$target = $result["target"];
echo "<li><a href='index.php?id=$id&title=$title&target=$target'>$title</a></li>";
}
?>

上面的代码将遍历我的数据库并获取链接。

我的数据库中的表有3列，分别是“id，menu_title，target”。

我添加了“目标”列，以便与$ _GET一起使用，因此它会向我显示不同的内容。

此外，我创建了about_us.php文件，以便在按下“关于我们”链接时将用户带到该页面。

我的问题是如何更改网站的链接以显示有关该特定链接的内容？例如“Home”show index.php“About Us”仅显示about_us.php内容，“Contact Us”显示contact_us.php内容

Index.php工作正常，我遇到的问题是其他链接内容。

请解释我如何使用链接工作并在按下关于我们的链接时打开about_us.php文件，联系我们也是如此。

感谢。

Answer 1

您需要include index.php内的$target.php页面文件。

这将在index.php中将while()的内容嵌入到您选择的任何位置。我建议将其置于生成链接的if($target == "index"){ //dont include a page here as you're already in index and you don't want the page to include itsself. } else { include($target.".php"); }循环下方。

$id

在axiac的问题评论中提到的一些内容也值得注意。

自PHP 5.5起，不推荐使用mysql_扩展，自PHP 7.0起删除。更改扩展名很简单，您应该使用其中一个指向文档的链接。 mysqli_或PDO mysql。
$id = $_GET["id"];和$title在您的代码中是多余的。您只使用数据库表行的$target和content属性。

编辑：特定于您的索引页面，您需要将index.php indexcontent.php移动到另一个文件index.php。这样可以使主要内容与网页的状态部分分开，例如导航和内容区域。

或者，您可以将内容保留在index.php内，并将if语句包含在我在下面分隔的内容中。

然后您将拥有以下内容：

<?php error_reporting(E_ERROR | E_PARSE); include ("includes/layouts/header.php"); include ("includes/database/db.php"); $id = $_GET["id"]; $target = $_GET["target"]; ?>  <div class='container-fluid col-xs-12'> <div class='carousel_bg'> <div id='carousel' class='owl-carousel owl-theme'> <img src='images/slideshow_imgs/adele_slideshow.jpg' alt='adele_photo'> <img src='images/slideshow_imgs/multiple_covers_slideshow.jpg' alt='multiple_music_covers_photo'> <img src='images/slideshow_imgs/oranged_up_slideshow.jpg' alt='oranged_up_photo'> <img src='images/slideshow_imgs/random_covers_slideshow.jpg' alt='random_music_covers'> <img src='images/slideshow_imgs/sean_tizzle_slideshow.jpg' alt='sean_tizzle_photo'> </div> </div> </div>  <?php if($target == "index"){ include("indexcontent.php"); } else { include($target.".php"); } ?> <?php include ("includes/layouts/footer.php"); ?>

indexconent.php
