我目前正在开发预订系统。当管理员登录时他/她必须能够更新数据。我正在尝试上传图像以更新图像，但每次我尝试这样做时，都会收到两条警告消息。以下是我收到的警告信息。
Warning: move_uploaded_file(../production_images/113.jpg): failed to open stream: Permission denied in /home/www/TheatreWebsite/storeadmin/inventory_edit.php on line 87
Warning: move_uploaded_file(): Unable to move '/tmp/phpDt7qFp' to '../production_images/113.jpg' in /home/www/TheatreWebsite/storeadmin/inventory_edit.php on line 87
以下是我的PHP代码：
<?php
if (isset($_POST['productiontype'])) {
//$pid = mysql_real_escape_string($_POST['thisID']);
$pid = mysqli_real_escape_string($db_con,$_POST['thisID']);
$productionname = mysqli_real_escape_string($db_con,$_POST['productionname']);
$productiontype = mysqli_real_escape_string($db_con,$_POST['productiontype']);
$description = mysqli_real_escape_string($db_con,$_POST['description']);
$q1 = "UPDATE Production SET productionname = '$productionname', productiontype='$productiontype', description='$description' WHERE productionid='$pid'"; $sql = $db_con->query($q1);
if ($_FILES['filefield']['tmp_name'] != "") {
// Place image in the folder
$newname = "$pid.jpg";
echo '<script language="javascript">';
//$pid = mysqli_real_escape_string($db_con,$_POST['thisID']);
echo "alert('$newname')";
echo '</script>';
move_uploaded_file($_FILES['filefield']['tmp_name'], "../production_images/".$newname);
}
}
?>
<?php
// Gather this product's full information for inserting automatically into the edit form below on page
if (isset($_GET['pid'])) {
$targetID = $_GET['pid'];
$sql = "SELECT * FROM Production WHERE productionid='$targetID' LIMIT 1";
$sql = mysqli_query($db_con,$sql);
$productCount = mysqli_num_rows($sql); // count the output amount
if ($productCount > 0) {
while($row = mysqli_fetch_array($sql,MYSQLI_ASSOC)){
$pid = $row["productionid"];
$productionname = $row["productionname"];
$productiontype = $row["productiontype"];
$description = $row["description"];
}
} else {
echo "Sorry that Production doesn't exist.";
exit();
}
}
?>

检查路径/production_images/上的权限。这似乎是最可能的问题。该路径要么不是您的服务器用户可写，要么该路径不存在。
