[英]How to make breadcrumb of specific part of URL
我必须为网站的每个页面生成面包屑,其中url有点复杂。
这是我的网址
现在我必须在“route =”之后从url获取“enterprise / projects / manage”并生成每个路由的breadcrumb。
下面是我正在使用的PHP代码,它只会像这个“Home >> Company”那样创建面包屑,而我需要像这样的“企业>>项目>>管理”这样的面包屑。
// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' » ', $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, $breadcrumbs);
//return parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
}
?> `
由于您只需要路由参数,因此您需要将其从网址中挖掘出来。
这是一个只提取路径参数的函数。
function getRouteParamAsArray($url) {
// Get the query part of the url. i.e. after the ?
$query = parse_url($url, PHP_URL_QUERY);
// echo "query = $query\n";
// explode it into parts a=1, b=2 etc
$parts = explode('&', $query);
// echo print_r($parts, true) . "\n";
// Now covert the parts into key value pairs
// by taking each item and exploding on '='
$arr = [];
array_walk($parts, function($item) use (&$arr)
{
// echo "$item\n";
$a = explode('=', $item, 2); // convert into key/value
$key = $a[0];
$value = $a[1] ?? null; // just in case
$arr[$key] = $value;
});
// Now we have key value pairs
//echo print_r($arr, true) . "\n";
// See if there is a 'route' key
if ( array_key_exists('route', $arr) ) {
$routeParts = explode('/', $arr['route']);
} else {
$routeParts = [];
}
// echo print_r($routeParts, true) . "\n";
// echo 'breadcrumb: ' . implode(' > ', $routeParts) . "\n";
return $routeParts;
}
将它集成到您的功能中:
function breadcrumbs($separator = ' » ', $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
$path = getRouteParamAsArray($_SERVER['REQUEST_URI']);
// 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}Company/">$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
$crumbPath = '';
foreach ($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('', ' '), $crumb));
if ( ! empty($crumbPath) ) {
$crumbPath .= '/';
}
$crumbPath .= $crumb;
// If we are not on the last index, then display an <a> tag
if ($x != $last)
$breadcrumbs[] = "<a href=\"{$base}Company/?route={$crumbPath}\">$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, $breadcrumbs);
//return parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
