我想在wordpress的前端插入newpost
我想在上载过程中重命名图像名称for my code below
结果如下：“MemberUpload\\uem>日/月/年\\u random\\u number\\u[宽度]x[高度]。jpg”
（适用于所有大小：缩略图、中、大、全尺寸和自定义大小）我的代码上载我用于我的主题<（非常感谢朋友们！）

// Upload

                if ($attach_id > 0){
                    //and if you want to set that image as Post  then use:
                    update_post_meta($newPost,\'Uploaded_img_id\',$attach_id);
                }
// END upload
