與PHP的問題上傳

Question

我的代碼：

if(isset($_FILES['image'])){ 
    $allowedExts = array('jpg', 'gif', 'png'); 
    $extension = end(explode('.', $_FILES['image']['name'])); 
    if(in_array($extension, $allowedExts)){ 
     if($_FILES['image']['size'] < 50000){ 
      if ($_FILES['image']['error'] > 0){ 
       $uploaderror = $_FILES['image']['error']; 
      }else{ 
       $uploaderror = 'FALLBACK ERROR'; 
       if(file_exists('..images/'.$_FILES['image']['name'])){ 
        $uploaderror = 'The file <strong>'.$_FILES['image']['name'].'</strong> already exists in the images directory.'; 
       }else{ 
        move_uploaded_file($_FILES['file']['tmp_name'], '..images/'.$_FILES['file']['name']); 
        $uploadsuccess = $_FILES['file']['name']; 
       } 
      } 
     }else{$uploaderror = 'The image is too large.';} 
    }else{$uploaderror = 'Only images (.jpg, .png, and .gif) are allowed.';} 
}else{$uploaderror = 'No attempt';} 

輸出： $uploaderror回報FALLBACK ERROR和$uploadsuccess沒有設置。該文件沒有出現在指定的目錄中，我無法在服務器上找到它。請告訴我我做錯了什麼。謝謝！

Answer 1

你失蹤後/的..和images前，要解決這個問題只是改變這一點：

move_uploaded_file($_FILES['file']['tmp_name'], '..images/'.$_FILES['file']['name']); 

以下幾點：

move_uploaded_file($_FILES['file']['tmp_name'], '../images/'.$_FILES['file']['name']); 

與您的代碼通過一個終端，你可以運行得到以下回應：

..images：沒有這樣的文件或目錄

編輯

我發現了另一個地方，你忘了/，這是你的file_exists()檢查。

我已經清理你的代碼也使其更具可讀性：

<?php 
$errors = array(); 
$allowedExts = array('jpg', 'gif', 'png'); 
$extension = pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION); 
if(!isset($_FILES['image'])){ 
    $errors[] = "No attempt."; 
} 
if(in_array($extension, $allowedExts)){ 
    $errors[] = "Only images (.jpg, .png, and .gif) are allowed."; 
} 
if($_FILES['image']['size'] > 50000){ 
    $errors[] = "The image is too large."; 
} 
if ($_FILES['image']['error'] <= 0){ 
    $errors[] = $_FILES['image']['error']; 
} 
if(file_exists('../images/'.$_FILES['image']['name'])){ 
    $errors[] = 'The file <strong>'.$_FILES['image']['name'].'</strong> already exists in the images directory.'; 
} 

// No errors found! 
if(count($errors) == 0){ 
    move_uploaded_file($_FILES['file']['tmp_name'], '../images/'.$_FILES['file']['name']); 
    $uploadsuccess = $_FILES['file']['name']; 
}
