推荐答案

您需要检查/验证图像是否已上传或不尝试类似的操作

you need to check/validate that image is upload or not try something like that

if (!empty($_FILES['image']['name'])) {
   $image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
   $image_name = addslashes($_FILES['image']['name']);
}else{
   $image = '';
   $image_name = '';
}
