类别列表，而不是管理选项中的下拉菜单选择器

时间：2012-02-21 作者：Marion

我在管理区域中使用以下代码theme options 

$categories = get_categories(\'hide_empty=0&orderby=name\');  
$tz_wp_cats = array();  
foreach ($categories as $category_list ) {  
    $tz_wp_cats[$category_list->cat_ID] = $category_list->cat_name;  
    }  
array_unshift($tz_wp_cats, "Choose a category");

// ==========================//
//             Start the theme options!                  //
// ==========================//

    $themename = "Hype";
    $shortname = "tz";

    $options = array (

    array(  "name" => __("selected", \'framework\'),
    "id" => $shortname."_selectedtab",
    "std" => "",
    "type" => "hidden"),

    array(  "type" => "opentab"),

    array(  "type" => "open"),


    array(  "name" => __(\'Logo and Favicon Settings\', \'framework\'),
    "id" => $shortname."_logo_settings",
    "type" => "title"),

    array(  "name" => __("Upload Logo", \'framework\'),
    "desc" => __("Enter the full URL of an image you would like to use as a logo e.g http://www.example.com/logo.png", \'framework\'),
    "id" => $shortname."_logo_url",
    "std" => "",
    "type" => "file"),

    array(  "name" => __("Enable plain text logo",\'framework\'),
    "desc" => __("Check this box to use a plain text logo rather than an image. Info will be taken from your WordPress settings.", \'framework\'),
    "id" => $shortname."_plain_logo",
    "std" => "false",
    "type" => "checkbox"),

    array(  "name" => __("Favicon URL", \'framework\'),
    "desc" => __("Enter the full URL of your favicon e.g. http://www.example.com/favicon.ico", \'framework\'),
    "id" => $shortname."_favicon_url",

    array(  "type" => "close"),

所以看起来this example

我想列出所有类别并自动生成唯一ID。我只能选择下拉菜单，但我需要to list all categories; i.e.类似于

array(  "name" => __("Categories", \'framework\'),
"desc" => __("Category color #1", \'framework\'),
"id" => $shortname."_cat_color#1",
"std" => "#",
"type" => "text"
"desc" => __("Category color #2", \'framework\'),
"id" => $shortname."_cat_color#2",
"std" => "#",
"type" => "text"
"desc" => __("Category color #3", \'framework\'),
"id" => $shortname."_cat_color#3",
"std" => "#",
"type" => "text"),
有什么建议吗？

在这种情况下，您可以获得类别列表，并为每个类别创建如下文本字段：

$categories = get_categories(\'hide_empty=0&orderby=name\');
foreach ($categories as $cat){
    $options[] = array( 
    "name" => $cat->name,  
    "desc" => "Select a color for ".$cat->name." category",  
    "id" => $shortname."_cat_".$cat->term_id,  
    "type" => "text",  
    "std" => "");  
}

结束

是否有一个小部件可以根据发布日期列出最新的x类别，基本上提供最近活动主题的列表？
