它是一个简单的代码。我希望每次上传文件时都在数据库中保留记录。当每次上传任何文件时,我希望用户从数据库中查看他/她所有上传的文件。上传文件时保存的记录工作正常。但是在获取包含所有上载文件信息的表时会出现问题。
//connetion code
$con = mysqli_connect("localhost", "root", "", "sss");
if (mysqli_connect_errno())
{
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
//file upload code
move_uploaded_file($_FILES["file"]["tmp_name"],"C:/xampp/htdocs/" . $_FILES["file"]["name"]);
mysqli_query($con, "INSERT INTO uploads ( filename, uploaded_on) VALUES ( '{$_FILES['file']['name']}', NOW());");
echo "Stored in: " . "C:/xampp/htdocs/" . $_FILES["file"]["name"];
//fetch rows
$result =mysqli_query($con, "select * from uploads");
while ($row = mysqli_fetch_array($result))
{
printf ("%s\n", $row);
}
mysqli_close($con);
}
我觉得编码有一些严重的问题。这是我第一次在mysqli工作,之前我习惯使用mysql编写代码。需要帮助来了解实际问题和解决方案。
编辑: 它返回这个,
Notice: Array to string conversion in C:\xampp\htdocs\sss\upload_file.php on line 68
Array
Notice: Array to string conversion in C:\xampp\htdocs\sss\upload_file.php on line 68
Array
Notice: Array to string conversion in C:\xampp\htdocs\sss\upload_file.php on line 68
Array
但不幸的是,这段代码是巨大代码的一部分。所以这里第68行是$result = mysqli_query($con, "select * from uploads");
开始的行。
答案 0 :(得分:2)
$result =mysqli_query($con, "select * from uploads");
while ($row = mysqli_fetch_assoc($result))
{
printf ("%s\n", $row['column_name_1']);
printf ("%s\n", $row['column_name_2']);
printf ("%s\n", $row['column_name_3']);
}
mysqli_close($con);
但是你应该认真考虑查看代码的安全性。
