7b2主题通过自定义栏目增加文章来源网站开发

主题functions.php内添加如下代码：

if ( !class_exists(‘myCustomFields’<span%20class=”br0″>) ) {

class myCustomFields {

/**

* @var string $prefix 自定义栏目前缀，一个完整的自定义栏目是需要前缀+name的，比如我的前缀是git_,name下面有baidu_submit，那么完整的自定义栏目就是git_baidu_submit.

var $prefix = ”<span%20class=””>;

/**

* @var array $postTypes 这是自定义面板的使用范围，这里一般就是在文章以及页面

var $postTypes = array( “page”, “post”, “product” , “gallery” );

/**

* @var array $customFields 开始组件自定义面板数组

var $customFields = array(

array(

“name” => “f”,

“title” => “转载来源名字”,

“description” => “这里可以输入文章转载名字，不填写的话，不显示转载标签”,

“type” => “text”,

“scope” => array( “post”, “page” ),

“capability” => “edit_posts”

array(

“name” => “furl”,

“title” => “转载来源链接”,

“description” => “这里可以输入您的转载来源链接”,

“type” => “text”,

“scope” => array( “post”, “page” ),

“capability” => “edit_posts”

)

);
