一切正常，我可以将查询单独插入数据库，但不会移动上传的文件这是我的代码。如果您在下面找到任何问题，请参阅。
它检查了我的图像文件夹目录，正确的目录将我带到了正确的文件夹。php.ini中也启用了upload_file但仍然无法正常工作。
<?php
$conn = mysqli_connect("localhost", "root", "HERE_IS_MYCORRECT_PASSWORD", "HERE_IS_MYCORRECT_DTABASE_NAME");
if($conn) {
echo "<p style='color:green;'>connected</p>";
}
else {
echo " connection failed";
}
if(isset($_POST['uploadfilesub'])){
$id = $_POST['id'];
$filename = $_FILES['uploadfile']['name'];
$filetmpname = $_FILES['uploadfile']['tmp_name'];
$folder = './Resources/style/images/' . $filename;
echo "<p>".$filename."</p>";
echo "<p>".$filetmpname."</p>";
$sql = "INSERT INTO product_images VALUES ($id,'$filename') ";
if(move_uploaded_file($filetmpname , $folder)){
echo "<p color='green'>moved</p>";
$qry = mysqli_query($conn, $sql);
if($qry){
echo "<p color='green'>Inserted into mysql</p>";
} else {
echo "<p color='red'>Failed to Insert</p>";
}
}
else {
echo "<p style='color:red;'>Failed to move</p>";
}
}
?>

据我所见，您的错误（关于所提到的特定问题）非常简单：
$folder = './Resources/style/images/';
更改为：
$folder = './Resources/style/images/' . $filename;
仅move_uploaded_file需要完整的目标路径，而不仅是目标文件夹。
