Question

我不知道我的鳕鱼有什么问题。当我提交我的图片时，我没有收到任何错误，并且我获得了成功。当我检查我的数据库表以查看图像名称是否已被上传时，我只得到一个空白的表格行，只插入了ID，除此之外别无其他我也没有在文件夹中获取图像。

Answer 1

使用预准备语句插入数据库。就像这个..

$query_image = mysqli_prepare($connection,"INSERT INTO shirt_table (images1, images2, images3, images4) 
    values(?,?,?,?)");//$connection is database connection object

mysqli_stmt_bind_param($query_image,"ssss",$_FILES['file1']['name'], $_FILES['file2']['name'], $_FILES['file3']['name'], $_FILES['file4']['name']);
mysqli_stmt_execute($query_image );

您还没有在插入查询中使用图片名称。

图像名称不会上传到数据库
