如何将自定义帖子类型存档添加到菜单

谢谢

感谢rasmussvanejensen为她/他的漂亮的问题,thethangtran的答案,我仍然感到困惑,为什么WordPress的还没有添加这么好的功能,默认情况下,它的代码库.

顺便说一句,我认为甚至比thengtran提供的解决方案更好,因为它可能会在某些情况下破坏.

注1

根据Codex,使用register_post_type,可以post_type为安装添加额外的s.有机会,有些人需要更改'query_var',因此提供的代码将会中断.

笔记2

此外,它可能无法处理current-menu-item该类,该类将用于css自定义以将菜单项显示为活动状态.

注3

由于在代码中的另一个音符,就没有必要来定义loop_index,item而items变量.他们绝对没用.

更好的解决方案

所以我建议使用这个替代方案,对于那些想要更强大的解决方案的人:

function prefix_add_metabox_menu_posttype_archive(){
  add_meta_box( 'prefix_metabox_menu_posttype_archive', __( 'Archives' ), 'prefix_metabox_menu_posttype_archive', 'nav-menus', 'side', 'default' );
}
add_action( 'admin_head-nav-menus.php', 'prefix_add_metabox_menu_posttype_archive' );

function prefix_metabox_menu_posttype_archive(){
  $post_types = get_post_types( array( 'show_in_nav_menus' => true, 'has_archive' => true ), 'object' );

  if( $post_types ){

    foreach( $post_types as $post_type ){

      $post_type->classes = array( $post_type->name );
      $post_type->type = $post_type->name;
      $post_type->object_id = $post_type->name;
      $post_type->title = $post_type->labels->name;
      $post_type->object = 'cpt_archive';

    }

    $walker = new Walker_Nav_Menu_Checklist( array() );?>
    <div id="cpt-archive" class="posttypediv">
      <div id="tabs-panel-cpt-archive" class="tabs-panel tabs-panel-active">
        <ul id="ctp-archive-checklist" class="categorychecklist form-no-clear"><?php
        echo walk_nav_menu_tree( array_map( 'wp_setup_nav_menu_item', $post_types ), 0, (object) array( 'walker' => $walker ) );?>
        </ul>
      </div>
    </div>
    <p class="button-controls">
      <span class="add-to-menu">
        <input type="submit"<?php disabled( $nav_menu_selected_id, 0 ); ?> class="button-secondary submit-add-to-menu" value="<?php esc_attr_e( 'Add to Menu' ); ?>" name="add-ctp-archive-menu-item" id="submit-cpt-archive" />
      </span>
    </p><?php

  }

}

function prefix_cpt_archive_menu_filter( $items, $menu, $args ){

  foreach( $items as &$item ){
    if( $item->object != 'cpt_archive' ) continue;
    $item->url = get_post_type_archive_link( $item->type );
    if( get_query_var( 'post_type' ) == $item->type ){
      $item->classes []= 'current-menu-item';
      $item->current = true;
    }
  }
  return $items;

}
add_filter( 'wp_get_nav_menu_items', 'prefix_cpt_archive_menu_filter', 10, 3 );

要在菜单中添加"自定义posttype存档链接",请查看以下指南

打开文件functions.php,然后在下面输入代码

add_action('admin_head-nav-menus.php', 'wpclean_add_metabox_menu_posttype_archive');

function wpclean_add_metabox_menu_posttype_archive() {
add_meta_box('wpclean-metabox-nav-menu-posttype', __('Custom Post Type Archives'), 'wpclean_metabox_menu_posttype_archive', 'nav-menus', 'side', 'default');
}

function wpclean_metabox_menu_posttype_archive() {
$post_types = get_post_types(array('show_in_nav_menus' => true, 'has_archive' => true), 'object');

if ($post_types) :
    $items = array();
    $loop_index = 999999;

    foreach ($post_types as $post_type) {
        $item = new stdClass();
        $loop_index++;

        $item->object_id = $loop_index;
        $item->db_id = 0;
        $item->object = 'post_type_' . $post_type->query_var;
        $item->menu_item_parent = 0;
        $item->type = 'custom';
        $item->title = $post_type->labels->name;
        $item->url = get_post_type_archive_link($post_type->query_var);
        $item->target = '';
        $item->attr_title = '';
        $item->classes = array();
        $item->xfn = '';

        $items[] = $item;
    }

    $walker = new Walker_Nav_Menu_Checklist(array());

    echo '<div id="posttype-archive" class="posttypediv">';
    echo '<div id="tabs-panel-posttype-archive" class="tabs-panel tabs-panel-active">';
    echo '<ul id="posttype-archive-checklist" class="categorychecklist form-no-clear">';
    echo walk_nav_menu_tree(array_map('wp_setup_nav_menu_item', $items), 0, (object) array('walker' => $walker));
    echo '</ul>';
    echo '</div>';
    echo '</div>';

    echo '<p class="button-controls">';
    echo '<span class="add-to-menu">';
    echo '<input type="submit"' . disabled(1, 0) . ' class="button-secondary submit-add-to-menu right" value="' . __('Add to Menu') . '" name="add-posttype-archive-menu-item" id="submit-posttype-archive" />';
    echo '<span class="spinner"></span>';
    echo '</span>';
    echo '</p>';

endif;
}

你可以在你的functions.php中做一个简单的技巧:

add_filter('nav_menu_css_class', 'current_type_nav_class', 10, 2);
function current_type_nav_class($classes, $item) {
    // Get post_type for this post
    $post_type = get_query_var('post_type');

    // Go to Menus and add a menu class named: {custom-post-type}-menu-item
    // This adds a 'current_page_parent' class to the parent menu item
    if( in_array( $post_type.'-menu-item', $classes ) )
        array_push($classes, 'current_page_parent');

    return $classes;
}

在您的情况下,您只需要在管理面板中添加一个类"works-menu-item"和该归档菜单项;
