PHP "breadcrumbs" script

crystalattice · #1 09-Jan-2006, 22:59

Found this as part of the very useful The Grand Fandango PHP package. The package also includes What's New, What's Updated, and Navigation scripts. The Navigation script is especially nice since it's dynamic based on the folders you have on your web server. It's also GPLed.

This "breadcrumbs" script will automatically show where the user is in your directory tree in relation to Home.

PHP Code:


<!-- <alexpounds:noList /> -->

<?

include_once($_SERVER["DOCUMENT_ROOT"] . "/gfFunctions.php");
include_once($_SERVER["DOCUMENT_ROOT"] . "/userinfo.php");

function makeBreadcrumbs($path) {
    $pathEntries = explode("/", trim($path));
    global $myExtension;
    if (preg_match("%^/$%", trim($path)) || preg_match("%^/index\." . $myExtension . "$%", trim($path))) {
        // It's the top dir. 
        echo "Home"; 
    } else {
        echo "<a href=\"/\">Home</a>";
        $currentPath = "/";
        for ($i = 0; $i < count($pathEntries); $i++) {
            if ($i < count($pathEntries)-1) {
                if (!empty($pathEntries[$i])) {
                    echo " &gt; ";
                    $currentPath .= $pathEntries[$i] . "/";
                    if (trim($path) == $currentPath . "index." . $myExtension) {
                        echo getDirName($pathEntries[$i]);
                    } else {
                        echo "<a href=\"" . $currentPath . "\">" . getDirName($pathEntries[$i]) . "</a>";
                    }
                }
            } else {
                if (!(is_dir($_SERVER["DOCUMENT_ROOT"] . $path) || preg_match("%/index\." . $myExtension . "$%", trim($path)))) {
                    echo " &gt; ";
                    echo getPageName($_SERVER["DOCUMENT_ROOT"] . $path);
                }
            }
        }
    }
}
            
makeBreadcrumbs($_SERVER["PHP_SELF"]);
?>
