为当前菜单项定义当前页面

Question

我已经创建了一个由php的导航菜单。

1）我需要帮助如何更改当前页面的链接类。我的意思是例如，当主页打开时，链接应该像class =" bla bla current"

2）是否有任何建议，可以更好地链接到该按钮。这是代码

<?php
require_once('../config.php');  
$sql= "SELECT * FROM veri_kategori"; 
foreach ($dbh->query($sql) as $row)
{
echo "<li class="dropdown"><a href="".$row["link_tr"]."" class="dropdown-toggle">".$row["tr"]."</a></li>";
}
?>

Answer 1

尝试以下解决方案：

<?
    require_once('../config.php');  
    // Get the current page.
    $pag = $_GET['pag'];
    if (isset($pag)) {
        if ($page == 'about') {
            // Redirect or include your page.
        } else if ($page == 'contact') {
            // Redirect or include your page.
        }
    } else {
        // Redirect or include your home page.
    }
    $sql = "SELECT * FROM veri_kategori";
    foreach ($dbh->query($sql) as $row) {           
        // Set default class.
        $class = "dropdown-toggle";
        // If home page, set another class.
        if (!isset($pag)) {
            $class = "bla bla CURRENT";
        }       
        echo "<li class="dropdown"><a href="index.php?pag={$row["link_tr"]}" class="{$class}">{$row["tr"]}</a></li>";
    }
?>
