Question

使用以下脚本我试图：

上传图片
预览预览
将文件移至文件夹
在数据库中加载名称。

一切正常但图像名称未上传到数据库。我不明白错误，有人能帮助我吗？谢谢。

将文件移动到文件夹时，请插入图像名称。在这里你得到$ filename。

//将文件移动到文件夹

如果（空（$错误）== TRUE）{

  move_uploaded_file($file_tmp,"../../uploads/articoli/".$file_name);
  echo "File caricato";
  $sql = "INSERT INTO articoli (image) VALUES ('".file_name."' )";

}

使用php上传和预览文件并存储在数据库中
