PHP上傳失敗

Question

每當我上傳任何文件它說，

文件是圖像 - 圖像/ png.Sorry，上傳您的文件時出現錯誤。

我正在使用post方法和enctype =「multipart/form-data」。我的圖像文件也是適當的。

<?php 
    if(isset($_POST['submit'])){ 
    $target_dir = "pics/"; 
     $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
     $uploadOk = 1; 
     $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 
     // Check if image file is a actual image or fake image 
     if(isset($_POST["submit"])) { 
      $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]); 
      if($check !== false) { 
       echo "File is an image - " . $check["mime"] . "."; 
       $uploadOk = 1; 
      } else { 
       echo "File is not an image."; 
       $uploadOk = 0; 
      } 
     } 
     // Check if file already exists 
     if (file_exists($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."; 
      } 
     } 
    } 
?>

Answer 1

您的文件無法移動。

• 檢查路徑移動到
• 檢查目錄的權限
• 檢查與tmp目錄

您使用相對路徑的訪問權限：$target_dir = "pics/";

更改路徑爲：

$target_dir = $_SERVER['DOCUMENT_ROOT'] . '/pics/';
