php：简单的面包屑解决方案？

发布于 2024-09-28 20:20:07 字数 660 浏览 6 评论 0原文

嘿伙计们，我正在研究一个非常简单的面包屑路径解决方案，但是我有一件小事让我烦恼。

PATH 是例如文件夹/子文件夹/子子文件夹我只是分割路径并创建指向它的链接。真的很简单。

// breadcrumb path
$crumb = explode("/", PATH);
if (PATH != 'root' && realpath(PATH)) {
    print "<div class='breadcrumbs'>";
    $newpath = '';
    foreach($crumb as $value) {
        $newpath .= $value;
        print "<a href='" . QUERY . $newpath ."'>$value</a> &gt; ";
        $newpath .= '/';
    }
    print "</div>";
}

然而，唯一让我烦恼的是面包屑路径看起来像这样：

文件夹>子文件夹>子子文件夹>

你能看到>吗？在最后。即使那里没有另一个子子子文件夹，我得到这个>箭。当然，目前是这样设置的，但是我想不出一个简单的解决方案来摆脱最后一个箭头。

感谢您的帮助

hey guys,
i'm working on a very simple breadcrumb-path solution, however i have one little thing that kind of bugs me.

PATH is e.g. folder/subfolder/subsubfolder
i'm simply splitting the PATH and i'm creating links to it. really simpel.

// breadcrumb path
$crumb = explode("/", PATH);
if (PATH != 'root' && realpath(PATH)) {
    print "<div class='breadcrumbs'>";
    $newpath = '';
    foreach($crumb as $value) {
        $newpath .= $value;
        print "<a href='" . QUERY . $newpath ."'>$value</a> > ";
        $newpath .= '/';
    }
    print "</div>";
}

however the only thing that bugs me is that the breadcrumb path looks like this:

folder > subfolder > subsubfolder >

can you see the > at the end. even though there is not another subsubsubfolder there i'm getting this > arrow. of course it's currently set that way, however i cannot think of an easy solution to get rid of the last arrow.

thank you for your help

给你：

// breadcrumb path
$crumb = explode("/", PATH);
if (PATH != 'root' && realpath(PATH)) {
    print "<div class='breadcrumbs'>";
    $newpath = '';
    foreach($crumb as $index => $value) {
        $newpath .= $value;
        // is not last item //
        if($index < count($crumb)-1)
            print "<a href='" . QUERY . $newpath ."'>$value</a> > ";
        // it is last item //
        else
            print $value;
        $newpath .= '/';
    }
    print "</div>";
}

同时尝试为变量使用更具暗示性的名称。

Here you go:

// breadcrumb path
$crumb = explode("/", PATH);
if (PATH != 'root' && realpath(PATH)) {
    print "<div class='breadcrumbs'>";
    $newpath = '';
    foreach($crumb as $index => $value) {
        $newpath .= $value;
        // is not last item //
        if($index < count($crumb)-1)
            print "<a href='" . QUERY . $newpath ."'>$value</a> > ";
        // it is last item //
        else
            print $value;
        $newpath .= '/';
    }
    print "</div>";
}

Also try to use more suggestive names for your variables.

将您的代码更改为（未经测试！）：

// breadcrumb path
$crumb = explode("/", PATH);
if (PATH != 'root' && realpath(PATH)) {
    print "<div class='breadcrumbs'>";
    $newpath = '';
    foreach($crumb as $key=>$value) {
        $newpath .= $value;
        print "<a href='" . QUERY . $newpath ."'>$value</a>";
        if($key!= (count($crumb)-1) )print "> "
        $newpath .= '/';
    }
    print "</div>";
}

Change your code to (not tested!):

// breadcrumb path
$crumb = explode("/", PATH);
if (PATH != 'root' && realpath(PATH)) {
    print "<div class='breadcrumbs'>";
    $newpath = '';
    foreach($crumb as $key=>$value) {
        $newpath .= $value;
        print "<a href='" . QUERY . $newpath ."'>$value</a>";
        if($key!= (count($crumb)-1) )print "> "
        $newpath .= '/';
    }
    print "</div>";
}
