php - if else if 语句不适用于 get

Question

嘿伙计们，我在 if else if 和 $_GET 方面遇到了问题。我试图在页面上包含基于 GET 的页面。 导航代码

<a href="index.php?page=setting">Setting</a>
<a href="index.php?page=post">Post Article</a>

PHP 代码

<? 
if($_GET['page']=='post' && $_SESSION['status'] > 0 || $_GET['page']=='setting' && $_SESSION['status'] > 0)
{
include "page/post.php";

}else if{

include "page/setting.php";

}else{
include "page/home.php";
?>

如何解决这个问题？

Answer 1

更正 else if 的语法

else if 需要用括号括起来。

例如else if ($test == TRUE)

更正的代码:

if($_GET['page']=='post' && $_SESSION['status'] > 0) {
    include "page/post.php";
}
else if ($_GET['page']=='setting' && $_SESSION['status'] > 0) {
    include "page/setting.php";
}
else {
    include "page/home.php";
}
?>

更优化的代码:

if ($_SESSION['status'] > 0) {
    $pages = array();
    $pages['post'] = 'post';
    $pages['setting'] = 'setting';
    // You can add more pages, by adding entries in this array. 
    //e.g. $pages['about'] = 'about';
    if (isset($_GET['page']) && isset($pages[$_GET['page']])) {
        $page = $pages[$_GET['page']];
        include "page/" . $page . ".php";
    }
}
else {
    include "page/home.php";
}
