Question

我在web项目上使用uploadify，我不是特别是一个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。我得到没有.jpg扩展名的'1-profile'。任何人都可以放弃任何光明吗？

// 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？

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

// Validate the filetype
$fileParts = pathinfo($_FILES['Filedata']['name']);

应该是

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

// Validate the filetype

Uploadify丢失文件扩展名
