錯誤使用get_resutls在WordPress定製表

Question

我想顯示Appnames和的AppId列基於登錄的當前用戶。

global $wpdb; 
global $current_user; 
get_currentuserinfo(); 

$UserId= $current_user->ID; 


$siteAppIds = $wpdb->get_results($wpdb->prepare("SELECT AppID, AppNames FROM  
    app_BasicInfo WHERE WpUserId =$UserId, ARRAY_A")); 


foreach ($siteAppIds as $siteAppId) { 

echo $siteAppId-> AppNames; 
} 

任何想法，我在做什麼錯在這裏？

Answer 1

您正在使用ARRAY_A和呼應像object試試這個，

$siteAppIds = $wpdb->get_results($wpdb->prepare("SELECT AppID, AppNames FROM  
      app_BasicInfo WHERE WpUserId =$UserId, ARRAY_A")); 
foreach ($siteAppIds as $siteAppId) { 
    echo $siteAppId['AppNames']; 
} 

OR

$siteAppIds = $wpdb->get_results($wpdb->prepare("SELECT AppID, AppNames FROM  
      app_BasicInfo WHERE WpUserId =$UserId, OBJECT")); 
foreach ($siteAppIds as $siteAppId) { 
    echo $siteAppId->AppNames; 
}
