帮助使用Uploadify重命名文件

Question

This is my code -

<?php
session_start();
include('connect.php');
mysqli_select_db($connect, "users");
$s = "select * from name where sessionusername = '$u'";
$q = mysqli_query($connect, $s);
$f = mysqli_fetch_array($q);
$name = $f['name'];

if (!empty($_FILES)) {
    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
    $targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];

    // $fileTypes  = str_replace('*.','',$_REQUEST['fileext']);
    // $fileTypes  = str_replace(';','|',$fileTypes);
    // $typesArray = split('\|',$fileTypes);
    // $fileParts  = pathinfo($_FILES['Filedata']['name']);

    // if (in_array($fileParts['extension'],$typesArray)) {
        // Uncomment the following line if you want to make the directory if it doesn't exist
        // mkdir(str_replace('//','/',$targetPath), 0755, true);
        // Get the extension, and build the file name
     //$extension = pathinfo($tempFile, PATHINFO_EXTENSION); 
     $extension = end(explode(".",$_FILES['Filedata']["name"])); 
     $new_file_name =  '".$name."'".".$extension;

    $targetFile =  str_replace('//','/',$targetPath) . $new_file_name;
    // $targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];




        move_uploaded_file($tempFile,$targetFile);
        echo str_replace($_SERVER['DOCUMENT_ROOT'],'',$targetFile);
    // } else {
    //  echo 'Invalid file type.';
    // }
}

?>

Why is the above not working? As you can see, I am trying to pull down the name from the users database, and then rename the uploaded file to the name that was pulled from the db.

Can you help me out? Thanks a lot.

Answer 1

是表单enctype =='multipart / form-data'吗？

Ah, now I understand what you're talking about. You should remove your other post. This is an error I've actually encountered with Uploadify before, but I'm not sure what is going on here, specifically. Definitely, checkout your enctype, but for debugging, I implemented this solution for error reporting with Uploadify here: http://www.uploadify.com/forums/discussion/14/upload-script-error-reporting/p1 .
