我已经为wordpress管理面板创建了一个自定义图像上传程序，需要从wp\\U选项表中检索数据。我编写了以下函数：

//function to get all slider images
function getSliderImages(){
global $wpdb, $theme_shortname;
$query = "SELECT * FROM $wpdb->options AS o1 
WHERE o1.option_name LIKE \'%".$theme_shortname."_header_image%\'";
$imgs = $wpdb->get_results($query);

$images = array();
//loop through images and remove unusable results
foreach($imgs as $i){
    $id = substr($i[\'option_name\'],0,-1);
    if(is_numeric($id)){
        $images[] = $i[\'option_value\'];
    }
}

return($images);
}
