如何在樹枝中創建動態的麪包屑導航

我想在樹枝中創建動態的麪包屑導航。示例url www.example.com/section/page 我想獲取url，將其分割爲麪包屑，例如：home > section > page 我找到了這個可以工作的php代碼。任何人都可以幫助它轉換成樹枝？如何在樹枝中創建動態的麪包屑導航

<?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>

取得了一些進展...'{％組末頁= '嗒嗒' ％} \t

home

'不能工作，如何獲得，雖然當前頁面的名稱。需要弄清楚如何做一個'foreach'語句... – user3464091

這個http://stackoverflow.com/questions/2594211/php-simple-dynamic-breadcrumb?rq=1可能有幫助嗎？ – user3464091

您不需要該功能轉化爲Twig，你就可以告訴Twig通過擴展twig，以使該功能可在模板中爲您提供：

$twig = new Twig_Environment($loader); 
$function = new Twig_SimpleFunction('breadcrumb', function ($separator = ' &raquo; ', $home = 'Home') { 
    $path = array_filter(explode('/', parse_url($_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); 
}); 
$twig->addFunction($function);

然後，您可以使用此裏面twig功能，無論你想：

<!DOCTYPE html> 
<html> 
    <head> 
     <meta charset="UTF-8" /> 
    </head> 
    <body> 
     <nav> 
      {{ breadcrumbs() }} 
     </nav> 
    </body> 
</html>
