如何正确构建突出当前页面的导航菜单 [英] How to properly build a navigation menu that highlights the current page

问题描述

我已经为一个基于 icant.co.uk.这很简单，可能只有 5 页.这个小站点主要是一个mysql浏览器，用于一些使用MATE的表.有一个 common.php 文件，其中包含标题 &页脚 HTML，所以我把代码放在下面.

I've setup a menu for a fairly simple site based on icant.co.uk. It's fairly simple with maybe 5 pages. The small site is mainly a mysql browser for a few tables using MATE. Theres a common.php file that contains the header & footer HTML so thats where I put the code below.

下面的代码突出显示菜单上的当前页面.它很难看，我相信一定有更好的方法来做到这一点.

The code below highlights the current page on the menu. Its ugly and I'm sure there has to be a better way to do it.

感谢您的帮助，谢谢！

这是我的代码

<?php
        $currentFile = Explode('/', $_SERVER["PHP_SELF"]);
        $currentFile = $currentFile[count($currentFile) - 1];

        if ($currentFile == "orders.php"){
                echo '<li id="active"><a href="orders.php" id="current">Orders</a></li>';
        }
        else{
                echo '<li><a href="orders.php">Orders</a></li>';
        }

        if ($currentFile == "customers.php"){
                echo '<li id="active"><a href="customers.php" id="current">Customer List</a></li>';
        }
        else{
                echo '<li><a href="customers.php">Customer List</a></li>';
        }

        if ($currentFile == "order_details.php"){
                echo '<li id="active"><a href="order_details.php" id="current">Order Details</a></li>';
        }
        else{
                echo '<li><a href="order_details.php">Order Details</a></li>';
        }
?>

更新 对于那些好奇的人，下面是工作代码！

UPDATE For those curious, below is the working code!

<?php
    $currentFile = Explode('/', $_SERVER["PHP_SELF"]);
    $currentFile = $currentFile[count($currentFile) - 1];

    // easier to manage in case you want more pages later
    $pages = array(
        array("file" => "orders.php", "title" => "Orders"),
        array("file" => "order_details.php", "title" => "Order Details"),
        array("file" => "customers.php", "title" => "Customer List")
    );
    $menuOutput = '<ul>';
    foreach ($pages as $page) {
       $activeAppend = ($page['file'] == $currentFile) ? ' id="active"' : "";
       $currentAppend = ($page['file'] == $currentFile) ? ' id="current' : "";
       $menuOutput .= '<li' . $activeAppend . '>'
                   .  '<a href="' . $page['file'] . '"' . $currentAppend . '">' . $page['title'] .'</a>'
                   .  '</li>'; 
    }           
    $menuOutput .= '</ul>';

    echo $menuOutput;

?>

推荐答案

不确定这是否是你的意思，但这样你就可以摆脱这个丑陋的 if-else:

Not sure if that's what you meant, but this way you'll get rid of this ugly if-else:

$currentFile = Explode('/', $_SERVER["PHP_SELF"]);
$currentFile = $currentFile[count($currentFile) - 1];

// easier to manage in case you want more pages later
$pages = array(
    array("file" => "orders.php", "title" => "Orders"), 
    array("file" => "customers.php", "title" => "Customer List")
);
$menuOutput = '<ul>';
foreach ($pages as $page) {
   $activeAppend = ($page['file'] == $currentFile) ? ' id="active"' : "";
   $menuOutput .= '<li' . $activeAppend . '>'
               .  '<a href="' . $page['file'] . '">' . $page['title'] .'</a>'
               .  '</li>'; 
}           
$menuOutput .= '</ul>';

echo $menuOutput;
