我正试着做这样的东西。
<?php
class themeSettings {
private $key = \'themeSettings\';
public function __construct( $key ) {
global $post;
$post_id = $post->ID;
$settings = get_post_meta( $post_id, $this->key, true );
}
public function getData(){
print_r( $settings[\'post_description\'] );
}
}
$themeSettings = new themeSettings();
?>
<?php
// Print \'post_description\' values
getData();
?>
你能试试这个吗。这应该行得通。如果调用getData在主题文件中。您的键必须是静态值。之后你可以这样称呼它self::$key
使用方式如下：echo $theme->getData(get_the_ID()); 如果代码有效，请通知我：）
<?php
class themeSettings {
private static $key= \'themeSettings\'; // We Need to create a static value
public $id; // we nedd this for postID
public function __construct() {}
public function getData($id){
//$des = get_the_title($id); For Testing
$des = get_post_meta($id,self::$key,true);
/** All these area and If clause for testing */
if($des){
//return print_r($des); For testing
return print_r($des[\'post_description\']);
} else {
return \'Yok\';
}
}
}
$theme = new themeSettings();
/**
* Simple usage $theme->getData(get_the_ID());
* Dont add global WordPress values to classes.

我在我的query\\u帖子中有以下查询，希望向其中添加order by。Order by将位于另一个自定义字段上，并按desc Order排序。这是我现有的查询。//show all active posts for this taxonomy query_posts( array( \'post_type\' => APP_POST_TYPE, \'post_status\' => \'publish\', APP_CUSTOM_TAX
