插件开发过程中使用开发者工具<字段控件代码>工具生成的图片上传工具如何获取刚上传的图片地址？

<?php echo dr_fieldform('{"name":"打开图片","fieldname":"dakaitupian","ismain":"1","fieldtype":"File","setting":{"option":{"fieldtype":"","fieldlength":"","ext":"jpg,gif,png","size":"50","attachment":"0","image_reduce":"","is_ext_tips":"0","css":""},"validate":{"required":"0","pattern":"","errortips":"","check":"","filter":"","formattr":"","tips":""}},"ismember":"1"}', $dakaitupian, 1, 1);?>

图片上传成功后如何在标红区显示当前上传的图片路径？求指导
