Ich arbeite derzeit aneinem benutzerdefinierten Thema.In diesem Thema habeichein Menü,dasichmit register-nav-menu registriert habe,und dann zeigeich das Menümit der Funktion wp_nav_menu aufmeiner Webseite an.

Ichmöchtejedochnur die Liste der Menüelemente abrufen (nur dietatsächlichen Namen der Menüelemente,dieim wp-admin-Bereich zum Erstellen des Menüs verwendet wurden,und zwar ohne HTML),undichmöchte diese Liste der Elemente speichernzueinem Array (dhnicht anzeigen).

Ein Pseudo-Code würde also so aussehen

$menu_items = get_list_of_items($name_of_menu); // $name_of_menu is the result of register-nav-menu, and get_list_of_items is the psuedo function foreach ($menu_items as $item) { // do something with the item }

Gibteseine Möglichkeit,dies zutun?Danke.
I am currently am working on a custom theme. In this theme, I have a menu that I registered using register-nav-menu, and then I am displaying the menu to my web page using the wp_nav_menu function.

However, I like to retrieve the list of menu items only (the actual menu item names only that were used in wp-admin area to create the menu, and without any html), and I would like save that list of items to an array (i.e, not display it).

So, a psuedo code would look like this

$menu_items = get_list_of_items($name_of_menu); // $name_of_menu is the result of register-nav-menu, and get_list_of_items is the psuedo function foreach ($menu_items as $item) { // do something with the item }

Is there a way of doing so? Thanks.

Wie @vancodererwähnt,ist wp_get_nav_menu_items() der richtige Weg,aberich denke,eine detailliertere Antwort wärefür Menschenin Zukunft hilfreicher.

Diese Funktiongibt ein Array von WP_Post Object -Objekten zurück (Siegreifen alsomit einem Pfeil auf die Werte zu,z. B. $item->title).

Fürein grundlegendes Setup können Sie Folgendes verwenden:

$menuLocations = get_nav_menu_locations(); // Get our nav locations (set in our theme, usually functions.php) // This returns an array of menu locations ([LOCATION_NAME] = MENU_ID); $menuID = $menuLocations['primary']; // Get the *primary* menu ID $primaryNav = wp_get_nav_menu_items($menuID); // Get the array of wp objects, the nav items for our queried location.

Dann können Sieeinfach die Variable $primaryNav durchlaufen,zum Beispiel:

foreach ( $primaryNav as $navItem ) { echo '<li><a href="'.$navItem->url.'" title="'.$navItem->title.'">'.$navItem->title.'</a></li>'; }
As @vancoder mentions, wp_get_nav_menu_items() is the way to go, however I think a better detailed answer would be more helpful for people in the future.

Said function returns an array of WP_Post Object objects (so you access the values with an arrow, eg. $item->title).

For a basic setup, you could use the following:

$menuLocations = get_nav_menu_locations(); // Get our nav locations (set in our theme, usually functions.php) // This returns an array of menu locations ([LOCATION_NAME] = MENU_ID); $menuID = $menuLocations['primary']; // Get the *primary* menu ID $primaryNav = wp_get_nav_menu_items($menuID); // Get the array of wp objects, the nav items for our queried location.

Then you can just loop over that $primaryNav variable, for example:

foreach ( $primaryNav as $navItem ) { echo '<li><a href="'.$navItem->url.'" title="'.$navItem->title.'">'.$navItem->title.'</a></li>'; }
- fürmichgibt dies "falsch" zurück
  
  to me this returns "false"

- Kopieren Sie @JohnSmith?Siemüssen die ID Ihres Menüs verwenden.
  
  Are you copy-pasting @JohnSmith? You'll need to use _your_ menu's ID.

Holen Sie sichein einfaches Menü.

Zu Funktionen hinzufügen.php

     function wp_get_menu_array($current_menu) {

    $array_menu = wp_get_nav_menu_items($current_menu);
    $menu = array();
    foreach ($array_menu as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID'] = $m->ID;
            $menu[$m->ID]['title'] = $m->title;
            $menu[$m->ID]['url'] = $m->url;
            $menu[$m->ID]['children'] = array();
        }
    }
    $submenu = array();
    foreach ($array_menu as $m) {
        if ($m->menu_item_parent) {
            $submenu[$m->ID] = array();
            $submenu[$m->ID]['ID'] = $m->ID;
            $submenu[$m->ID]['title'] = $m->title;
            $submenu[$m->ID]['url'] = $m->url;
            $menu[$m->menu_item_parent]['children'][$m->ID] = $submenu[$m->ID];
        }
    }
    return $menu;
}

Gehen Sie zu Ihrer Header- und Aufruffunktion

 <?php
 $a = wp_get_menu_array('top-menu-header');                         
 print_r($a); exit;                       

?>

Get simple array of menu.

Add To Functions.php

    function wp_get_menu_array($current_menu) {

    $array_menu = wp_get_nav_menu_items($current_menu);
    $menu = array();
    foreach ($array_menu as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID'] = $m->ID;
            $menu[$m->ID]['title'] = $m->title;
            $menu[$m->ID]['url'] = $m->url;
            $menu[$m->ID]['children'] = array();
        }
    }
    $submenu = array();
    foreach ($array_menu as $m) {
        if ($m->menu_item_parent) {
            $submenu[$m->ID] = array();
            $submenu[$m->ID]['ID'] = $m->ID;
            $submenu[$m->ID]['title'] = $m->title;
            $submenu[$m->ID]['url'] = $m->url;
            $menu[$m->menu_item_parent]['children'][$m->ID] = $submenu[$m->ID];
        }
    }
    return $menu;
}

Go to Your Header And Call Function

<?php
 $a = wp_get_menu_array('top-menu-header');                         
 print_r($a); exit;                       

?>

Geänderte Version von obenmit rekursiven Schleifen.

Zu Funktionen hinzufügen.php

 function wp_get_menu_array($current_menu='Main Menu') {

    $menu_array = wp_get_nav_menu_items($current_menu);

    $menu = array();

    function populate_children($menu_array, $menu_item)
    {
        $children = array();
        if (!empty($menu_array)){
            foreach ($menu_array as $k=>$m) {
                if ($m->menu_item_parent == $menu_item->ID) {
                    $children[$m->ID] = array();
                    $children[$m->ID]['ID'] = $m->ID;
                    $children[$m->ID]['title'] = $m->title;
                    $children[$m->ID]['url'] = $m->url;
                    unset($menu_array[$k]);
                    $children[$m->ID]['children'] = populate_children($menu_array, $m);
                }
            }
        };
        return $children;
    }

    foreach ($menu_array as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID'] = $m->ID;
            $menu[$m->ID]['title'] = $m->title;
            $menu[$m->ID]['url'] = $m->url;
            $menu[$m->ID]['children'] = populate_children($menu_array, $m);
        }
    }

    return $menu;

}

Modified version of above with recursive loops.

Add To Functions.php

function wp_get_menu_array($current_menu='Main Menu') {

    $menu_array = wp_get_nav_menu_items($current_menu);

    $menu = array();

    function populate_children($menu_array, $menu_item)
    {
        $children = array();
        if (!empty($menu_array)){
            foreach ($menu_array as $k=>$m) {
                if ($m->menu_item_parent == $menu_item->ID) {
                    $children[$m->ID] = array();
                    $children[$m->ID]['ID'] = $m->ID;
                    $children[$m->ID]['title'] = $m->title;
                    $children[$m->ID]['url'] = $m->url;
                    unset($menu_array[$k]);
                    $children[$m->ID]['children'] = populate_children($menu_array, $m);
                }
            }
        };
        return $children;
    }

    foreach ($menu_array as $m) {
        if (empty($m->menu_item_parent)) {
            $menu[$m->ID] = array();
            $menu[$m->ID]['ID'] = $m->ID;
            $menu[$m->ID]['title'] = $m->title;
            $menu[$m->ID]['url'] = $m->url;
            $menu[$m->ID]['children'] = populate_children($menu_array, $m);
        }
    }

    return $menu;

}

wp_get_nav_menu_items scheintgenau das zu sein,was Siebenötigen.Esgibt ein Array von Menüobjekten zurück.
