Uploadify缺少文件扩展名

Question

我在web项目上使用uploadify，我不是一个特别的php专家，所以我很难理解为什么以下结果导致上传的图像没有有效的扩展名。我没有.jpg扩展名而获得'1-profile'。任何人都可以摆脱任何光线？

<?php

// Set the uplaod directory 
$uploadDir = '/img/profiles/'; 

// Set the allowed file extensions 
$fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions 

$verifyToken = md5('unique_salt' . $_POST['timestamp']); 

if (!empty($_FILES) && $_POST['token'] == $verifyToken) { 

    rename($_FILES['Filedata']['name'], $_POST['user_id'].'-profile'); 

    $tempFile = $_FILES['Filedata']['tmp_name']; 
    $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; 

    $targetFile = $uploadDir .$_POST['user_id']. '-profile.'. strtolower($fileParts['extension']); 

    // Validate the filetype 
    $fileParts = pathinfo($_FILES['Filedata']['name']); 
    if (in_array(strtolower($fileParts['extension']), $fileTypes)) { 

     // Save the file 
     move_uploaded_file($tempFile, $targetFile); 
     echo 1; 

    } else { 

     // The file type wasn't allowed 
     echo 'Invalid file type.'; 

    } 
} 
?>

您是否在定义之前引用$fileParts？

​​

应该

$fileParts = pathinfo($_FILES['Filedata']['name']); 
$targetFile = $uploadDir .$_POST['user_id']. '-profile.'. strtolower($fileParts['extension']); 

// Validate the filetype
