根据面包屑级别动态获取页面 link

Dynamically get page link based on breadcrumb level

我正在尝试通过 PHP 创建一个面包屑菜单,目前有以下内容:

<?php

// 1. Get URL
$crumbs = explode("/",$_SERVER["REQUEST_URI"]);
$address = 'http://'.$_SERVER['HTTP_HOST'];

// 2. Strip extras
foreach($crumbs as $crumb){
    $crumb = ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' ');
    echo "<a href=".$address.">"."<span class='crumbMenu'>".$crumb."</span></a>";
}

?>

假设我有以下页面层次结构:Products > Products Level 2 > Products Level 3

上面的代码会吐出:

Products
Products Level 2
Products Level 3

这是正确的。但是,link 不是。

阅读 后,我确定我的方法是错误的,但不确定我可以采取什么其他方法来动态获取每个面包屑项目 link?

我得到的链接:

localhost:8080

我期待的链接:

您似乎忘记了将路由添加到 $address 变量,所以您所有的面包屑都指向基本服务器地址。尝试以下操作:

<?php

// 1. Get URL
$crumbs = explode("/",$_SERVER["REQUEST_URI"]);
$address = 'http://'.$_SERVER['HTTP_HOST'];

// 2. Strip extras
$build = $address.'/products';
foreach($crumbs as $crumb){
    if(in_array($crumb, [$_SERVER['HTTP_HOST'], 'products'])) {
        continue;
    }
    $build .= '/'.$crumb;
    $crumb = ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' ');
    echo "<a href=".$address.$build.">"."<span class='crumbMenu'>".$crumb."</span></a>";
}

?>

很难准备好你的回声,这没有帮助。我创建了一个小函数,它应该可以满足您的要求。随意修改它以满足您的需求。

$crumbs = "/x/y/z";
$address = "localhost:8080";

$crumbs = explode('/', $crumbs);
$end = '';
$href = '';
foreach ($crumbs as $crumb) {
    $crumb = str_replace('.php', '', $crumb);
    $end .= $crumb . ' ';
    $href .= $crumb . '/';
}

echo("HREF => " . $href);
echo("\n");
echo("TITLE => " . $end);
