简单的动态痕迹

Question

我觉得这个剧本大感兴趣的任何小白在这里:)包括我:)

我想创建一个小的代码，我可以在任何文件中使用，并会生成一个面包屑像这样：

如果文件被称为 “website.com/templates/index.php” 面包屑应显示：

Website.com > Templates 

  ^^链接                                        ^^纯文本

如果文件被称为 “website.com/templates/template_some_name.php” 面包屑应显示：

Website.com > Templates > Template Some Name 

  ^^链接                                      ^^链接                                ^^纯文本

Answer 1

嗯，从你给它的例子看起来像“$ _SERVER ['REQUEST_URI']”和explode()函数可以帮助你。您可以使用爆炸将域名后面的URL拆分为数组，并在每个正斜杠处将其分开。

作为一个非常简单的例子，像这样可以实现：

$crumbs = explode("/",$_SERVER["REQUEST_URI"]); 
foreach($crumbs as $crumb){ 
    echo ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' '); 
} 

Answer 2

使用parse_url然后输出结果在一个循环：

$urlinfo = parse_url($the_url); 
echo makelink($urlinfo['hostname']); 
foreach($breadcrumb in $urlinfo['path']) { 
    echo makelink($breadcrumb); 
} 

function makelink($str) { 
    return '<a href="'.urlencode($str).'" title="'.htmlspecialchars($str).'">'.htmlspecialchars($str).'</a>'; 
}

Answer 3

这可能是一个简单的面包屑矫枉过正，但它是值得一试。我记得很久以前我刚开始时遇到这个问题，但我从未真正解决过这个问题。也就是说，直到我决定现在写这个。 :)

我已经记录最好的我可以内联，底部是3个可能的用例。请享用！（随意问任何问题，你可能有）

<?php 

// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path 
function breadcrumbs($separator = ' &raquo; ', $home = 'Home') { 
    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values 
    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH))); 

    // This will build our "base URL" ... Also accounts for HTTPS :) 
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/'; 

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL) 
    $breadcrumbs = Array("<a href=\"$base\">$home</a>"); 

    // Find out the index for the last value in our path array 
    $last = end(array_keys($path)); 

    // Build the rest of the breadcrumbs 
    foreach ($path AS $x => $crumb) { 
     // Our "title" is the text that will be displayed (strip out .php and turn '_' into a space) 
     $title = ucwords(str_replace(Array('.php', '_'), Array('', ' '), $crumb)); 

     // If we are not on the last index, then display an <a> tag 
     if ($x != $last) 
      $breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>"; 
     // Otherwise, just display the title (minus) 
     else 
      $breadcrumbs[] = $title; 
    } 

    // Build our temporary array (pieces of bread) into one big string :) 
    return implode($separator, $breadcrumbs); 
} 

?> 

<p><?= breadcrumbs() ?></p> 
<p><?= breadcrumbs(' > ') ?></p> 
<p><?= breadcrumbs(' ^^ ', 'Index') ?></p> 

Answer 4

哎多米尼克你的答案是好的，但如果你有一个像http://localhost/project/index.php网站获得的重复“项目”链接，因为它是$基地的一部分，也出现在$路径数组。所以我调整并删除了$ path数组中的第一个项目。

//Trying to remove the first item in the array path so it doesn't repeat 
array_shift($path); 

我不知道如果这是最优雅的方式，但它现在适用于我。

我这一个13行或某事

// Find out the index for the last value in our path array 
$last = end(array_keys($path)); 

Answer 5

也做了使用RDFa（你也可以使用微资料或其他格式）Check it out on google 这个脚本也保持牢记您的网站的一个小脚本之前添加代码结构体。

function breadcrumbs($text = 'You are here: ', $sep = ' » ', $home = 'Home') { 
//Use RDFa breadcrumb, can also be used for microformats etc. 
$bc  = '<div xmlns:v="http://rdf.data-vocabulary.org/#" id="crums">'.$text; 
//Get the website: 
$site = 'http://'.$_SERVER['HTTP_HOST']; 
//Get all vars en skip the empty ones 
$crumbs = array_filter(explode("/",$_SERVER["REQUEST_URI"])); 
//Create the home breadcrumb 
$bc .= '<span typeof="v:Breadcrumb"><a href="'.$site.'" rel="v:url" property="v:title">'.$home.'</a>'.$sep.'</span>'; 
//Count all not empty breadcrumbs 
$nm  = count($crumbs); 
$i  = 1; 
//Loop the crumbs 
foreach($crumbs as $crumb){ 
    //Make the link look nice 
    $link = ucfirst(str_replace(array(".php","-","_"), array(""," "," ") ,$crumb)); 
    //Loose the last seperator 
    $sep  = $i==$nm?'':$sep; 
    //Add crumbs to the root 
    $site .= '/'.$crumb; 
    //Make the next crumb 
    $bc  .= '<span typeof="v:Breadcrumb"><a href="'.$site.'" rel="v:url" property="v:title">'.$link.'</a>'.$sep.'</span>'; 
    $i++; 
} 
$bc .= '</div>'; 
//Return the result 
return $bc;} 

Answer 6

我开始与多米尼克·巴恩斯的代码，从cWoDeR纳入反馈，我仍然不得不用面包屑问题在第三级的时候我用了一个子目录。所以我重写了它，并且包含了下面的代码。

请注意，我已经设置了我的网站结构，使得页面从属于（从链接）一个在根目录一级页面被设置如下：

• 与精确创建一个文件夹同名的文件（包括大小写），减去后缀，作为文件夹在根级别

• 地方下属的所有文件/页面到这个文件夹

（例如，如果想为Customers.php sobordinate页：

• 创建一个在同一水平Customers.php

• 称为客户文件夹中添加一个index.php文件将被重定向客户文件夹到该文件夹​​的主叫页面（请参阅下面的代码）

此结构将适用于多个级别的子文件夹。

只要确保你遵循上述文件结构，并插入一个index.php文件与每个子文件夹中显示的代码。

在每个子文件夹中的index.php页面的代码如下所示：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
<title>Redirected</title> 
</head> 
<body> 
<?php 
$root_dir = "web_root/" ; 
$last_dir=array_slice(array_filter(explode('/',$_SERVER['PHP_SELF'])),-2,1,false) ; 
$path_to_redirect = "/".$root_dir.$last_dir[0].".php" ; 
header('Location: '.$path_to_redirect) ; 
?> 
</body> 
</html> 

如果您使用的服务器的根目录作为Web根目录（即在/ var/www/html等），然后设置$ root_dir =“”:(不要在后面留下“/”）。如果你为你的网站使用了一个子目录（例如/ var/www/html/web_root，那么设置$ root_dir =“web_root /”;（用web目录的实际名称替换web_root）（确保包含尾部/）

无论如何，这是我的（衍生）代码：

<?php 

// Big Thank You to the folks on StackOverflow 
// See http://stackoverflow.com/questions/2594211/php-simple-dynamic-breadcrumb 
// Edited to enable using subdirectories to /var/www/html as root 
// eg, using /var/www/html/<this folder> as the root directory for this web site 
// To enable this, enter the name of the subdirectory being used as web root 
// in the $directory2 variable below 
// Make sure to include the trailing "/" at the end of the directory name 
// eg use  $directory2="this_folder/" ; 
// do NOT use $directory2="this_folder" ; 
// If you actually ARE using /var/www/html as the root directory,

// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path 
function breadcrumbs($separator = ' &raquo; ' , $home = 'Home') 
{ 

    // This sets the subdirectory as web_root (If you want to use a subdirectory) 
    // If you do not use a web_root subdirectory, set $directory2=""; (NO trailing /) 
    $directory2 = "web_root/" ; 

    // This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values 
    $path = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH) ; 
    $path_array = array_filter(explode('/',$path)) ; 

    // This line of code accommodates using a subfolder (/var/www/html/<this folder>) as root 
    // This removes the first item in the array path so it doesn't repeat 
    if ($directory2 != "") 
    { 
    array_shift($path_array) ; 
    } 

    // This will build our "base URL" ... Also accounts for HTTPS :) 
    $base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/'. $directory2 ; 

    // Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL) 
    $breadcrumbs = Array("<a href=\"$base\">$home</a>") ;

    { 
     // Our "title" is the text that will be displayed representing the filename without the .suffix 
     // If there is no "." in the crumb, it is a directory 
     if (strpos($crumb,".") == false) 
     { 
      $title = $crumb ; 
     } 
     else 
     { 
      $title = substr($crumb,0,strpos($crumb,".")) ; 
     } 

     // If we are not on the last index, then create a hyperlink 
     if ($crumb != $last) 
     { 
      $calling_page_array = array_slice(array_values(array_filter(explode('/',$path))),0,$crumb_counter,false) ; 
      $calling_page_path = "/".implode('/',$calling_page_array).".php" ; 
      $breadcrumbs[] = "<a href=".$calling_page_path.">".$title."</a>" ; 
     } 

     // Otherwise, just display the title 
     else

      $breadcrumbs[] = $title ; 
     } 

     $crumb_counter = $crumb_counter + 1 ;

这里是一个伟大简单的动态痕迹（根据需要调整）：

<?php 
    $docroot = "/zen/index5.php"; 
    $path =($_SERVER['REQUEST_URI']); 
    $names = explode("/", $path); 
    $trimnames = array_slice($names, 1, -1); 
    $length = count($trimnames)-1; 
    $fixme = array(".php","-","myname"); 
    $fixes = array(""," ","My<strong>Name</strong>"); 
    echo '<div id="breadwrap"><ol id="breadcrumb">'; 
    $url = ""; 
    for ($i = 0; $i <= $length;$i++){ 
    $url .= $trimnames[$i]."/"; 
     if($i>0 && $i!=$length){ 
      echo '<li><a href="/'.$url.'">'.ucfirst(str_replace($fixme,$fixes,$trimnames[$i]) . ' ').'</a></li>'; 
    } 
    elseif ($i == $length){ 
     echo '<li class="current">'.ucfirst(str_replace($fixme,$fixes,$trimnames[$i]) . ' ').'</li>';  
    } 
    else{ 
     echo $trimnames[$i]='<li><a href='.$docroot.' id="bread-home"><span>&nbsp;</span></a></li>'; 
    } 
} 
echo '</ol>'; 
?> 

Answer 8

一个更好的使用explode()功能如下...

不要忘记在超链接href中替换您的URL变量。

<?php 
    if($url != ''){ 
     $b = ''; 
     $links = explode('/',rtrim($url,'/')); 
     foreach($links as $l){ 
      $b .= $l; 
      if($url == $b){ 
       echo $l; 
      }else{ 
       echo "<a href='URL?url=".$b."'>".$l."/</a>"; 
      } 
      $b .= '/'; 
     } 
    } 
?>
