PHP圖片上傳 - 未定義fileToUpload

我有一個管理頁面，管理員將在窗體中插入一個新產品。我無法上傳圖片，得到未定義的fileToUpload錯誤。我需要上傳圖像並將圖像名稱存儲到數據庫中。PHP圖片上傳 - 未定義fileToUpload

這裏是我的代碼：

session_start(); 
include_once '../inc/config.php'; 

if(!isset($_SESSION['admin'])) 
{ 
    header('Location: login.php'); 
    exit; 
} 

if(isset($_POST['insert'])) 
{ 
$cname = mysqli_real_escape_string($connect, $_POST['cname']); 
$ccost = mysqli_real_escape_string($connect, $_POST['ccost']); 
$ctype = mysqli_real_escape_string($connect, $_POST['ctype']); 
$cimage = mysqli_real_escape_string($connect, $_POST['cimage']); 
$ccapa = mysqli_real_escape_string($connect, $_POST['ccapa']); 
$cstatus = mysqli_real_escape_string($connect, $_POST['cstatus']); 

$target_dir = "uploads/"; 
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
$uploadOk = 1; 
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 

$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]); 
if($check !== false) { 
    echo "File is an image - " . $check["mime"] . "."; 
    $uploadOk = 1; 
} else { 
    echo "File is not an image."; 
    $uploadOk = 0; 
} 

if (file_exists($target_file)) { 
echo "Sorry, file already exists."; 
$uploadOk = 0; 
} 
// Check file size 
if ($_FILES["fileToUpload"]["size"] > 500000) { 
echo "Sorry, your file is too large."; 
$uploadOk = 0; 
} 
// Allow certain file formats 
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType 
!= "jpeg" 
&& $imageFileType != "gif") { 
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed."; 
$uploadOk = 0; 
} 
// Check if $uploadOk is set to 0 by an error 
if ($uploadOk == 0) { 
echo "Sorry, your file was not uploaded."; 
// if everything is ok, try to upload file 
} else { 
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], 
$target_file)) { 
    echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has been uploaded."; 
} else { 
    echo "Sorry, there was an error uploading your file."; 
} 
} 

if(mysqli_query($connect, "INSERT INTO cars(car_name, car_type, image, rent_cost, capacity, status) VALUES 
    ('".$cname."', '".$ctype."', '". basename($_FILES["fileToUpload"]["name"]). "', '".$ccost."', '".$ccapa."', '".$cstatus."')")){ 
     $success = "<div class='alert alert-success'><strong>Successfully Inserted!</strong></div>"; 
    }else{ 
     $errormsg = "<div class='alert alert-danger'>Error inserting item.</div>"; 
    } 
}

我的HTML代碼：

嘗試以下操作：

添加enctype="multipart/form-data"到您的表單標籤
確保您的服務器可以接受POST和上傳數據是大到足以容納你的文件的大小
待辦事項一個print_r($_FILES)您的表格提交後，看看是否 $_FILES["fileToUpload"]定義爲

完成數1和2號3，我還沒有提交任何da但是，它的顯示錯誤 – Pidaus

你的腳本甚至不應該進入文件上傳得到處理的塊，除非isset（$ _ POST ['insert']）爲真。你能回覆你正在看到的確切的PHP錯誤嗎？還可以考慮在腳本的頂部放置一個print_r（$ _ REQUEST）來監視腳本獲得的輸入。 –

您需要在action=""後添加enctype="multipart/form-data"。否則發送到服務器的數據將不會被識別。

感謝那些回答我的問題的人。我已經解決了我的問題。。

對於不確定的變量，我只是需要把它isset內（$ _ POST（[ '插入']）
對於PHP上傳腳本，我只需要刪除： $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]); if($check !== false) { echo "File is an image - " . $check["mime"] . "."; $uploadOk = 1; } else { echo "File is not an image."; $uploadOk = 0; }
求是，ENCTYPE =「多部分/格式數據」是必需的標籤，以便將圖像/媒體發佈到服務器。

並固定它。
