将文件上传到服务器php

Question

I tested my code locally and everything works fine, I tried with 0777 and 0755 permissions on server for the folders and still the upload of a file is not working. My code is:

$ds = DIRECTORY_SEPARATOR;  

$storeFolder = '..\uploads';   

if (!empty($_FILES)) {
    foreach ($_FILES['file']['tmp_name'] as $key => $error) { 
        if ($error == UPLOAD_ERR_OK) {
            $tempFile = $_FILES['file']['tmp_name'][$key];    //temporary file                  

            $file_name = mt_rand(1000000,9999999); //generate the number for file name

            $imageName = $file_name.'.' . pathinfo($_FILES['file']['name'][$key],PATHINFO_EXTENSION); // set the new file name

            $targetPath = dirname( __FILE__ ) . $ds. $storeFolder . $ds; //target path where the image will be stored

            $targetFile =  $targetPath. $imageName;   // set the target path and image, url

            move_uploaded_file($tempFile,$targetFile); //move the uploaded file     

            echo 'BCK../uploads/'. $imageName;

        }
    }

}

I tried almost everything. And uploading is still not working. This .php script returns response like this:

BCK../uploads/5631131.jpg 

So obviously there is a file, but it is not uploaded.

HTML code is:

<form action="action.php" enctype="multipart/form-data" class="dropzone" style="float:left; background-image: url(design.png); ">
  <div class="fallback">
     <input name="file" type="file" multiple />
  </div>
</form>

Any help or advice would be appreciated since I now tried everything and still no result.

response i get local:

tempFile C:\xampp\tmp\php89FF.tmp
file_name 4337681
imageName 4337681.jpg
targetPath  C:\xampp\htdocs\designer\pk\../uploads\
targetFile  C:\xampp\htdocs\designer\pk\../uploads\4337681.jpg
BCK../uploads/4337681.jpg 

response i get on server:

tempFile /tmp/phpjs6s9x
file_name 5394604
imageName 5394604.jpg
targetPath  /var/www/designer/pk\..\uploads\
targetFile  /var/www/designer/pk\..\uploads\5394604.jpg
BCK../uploads/5394604.jpg 

Answer 1

try to change this line:

$storeFolder = '..\uploads';

to this:

$storeFolder = '..' . $ds .  'uploads';

You need to make create your target path folders if not created and consider not creating them if already exist. You need also to make sure that, the destination folder is writable. use "docroot" for referring to the root folder on your server. You can use something like this

        if($_FILES )
    {
        $user_id=$_GET['user_id'];
        $device_id=$_GET['device_id'];
        $backup_id=$_GET['backup_id'];
        $images_folder='images';
        $target_path=DOCROOT.$user_id.'\\'.$device_id.'\\'.$backup_id.'\\'.$images_folder.'\\';
        if ( ! is_dir($target_path) OR ! is_writable($target_path))
        {
            mkdir($target_path, 0777, TRUE);
        }
        $target_path = $target_path .$_FILES['uploadedfile']['size']. basename( $_FILES['uploadedfile']['name']);
        if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path))
        {
            $image_path=$target_path;
            $image_size=$_FILES['uploadedfile']['size'];
            $image = ORM::factory('image');
            $image=$image->new_image($_GET['backup_id'],$image_path,$image_size,$_GET['mobile_path'],file_get_contents($_FILES['uploadedthumb']['tmp_name']));
            echo "Server: Image: ".basename( $_FILES['uploadedfile']['name']).", uploaded successfully";
        } 
        else
        {
            echo "Server: Error";
        }

    }
    else
    {
        echo "no file attached";
    }

I tested your code and had to add a few things to make it work, which will most likely work for you as well.

method="post" was missing in:

<form action="action.php" enctype="multipart/form-data" class="dropzone" style="float:left; background-image: url(design.png); ">
  <div class="fallback">
     <input name="file" type="file" multiple />
  </div>
</form>

which is required when uploading files.

Also, missing square brackets for name="file" which should read as name="file[]" - It didn't work for me till I added it, because of the foreach argument.

foreach ($_FILES['file']['tmp_name'] as $key => $error)

The brackets are required when using a foreach and multiple files, so that it's treated as an array.

Your form should now read as:

<form action="action.php" method="post" enctype="multipart/form-data" class="dropzone" style="float:left; background-image: url(design.png); ">
  <div class="fallback">
     <input name="file[]" type="file" multiple />
     <input type="submit" name="submit" value="Upload">
  </div>
</form>

I added <input type="submit" name="submit" value="Upload"> since I didn't see it in your posted code.

You also could change $storeFolder = '..\\uploads'; to $storeFolder = '../uploads'; with a / instead of \\ but that might not make a difference, yet on some systems it does; I've seen it happen before.
