上传文件，创建两个新目录并将文件放置在PHP中

Question

When a user submits the form they enter a ref number and can upload up to 3 documents.

When they submit, i want the document to be saved in the folder structure like so:

 docs/
     12345/1/file.jpg
     12345/2/file.jpg
             anotherfile.jpg

     27635/1/afile.png
             anotherfile.png
             thirdfile.jpg

     34827/1/onefile.jpg

Okay so you get the idea, when a user uploads a file, it makes a new folder inside docs/ with their reference number then makes another folder called 1/with the files. if the user then uploads again with the same reference it will create a folder inside their reference with the next number up containing their files.

HTML:

    <form action="upload.php" method="post" enctype="multipart/form-data">

        <input type="text" name="reference"/><br/>
        <input type="file" name="pictures[]" /><br/>
        <input type="file" name="pictures[]" /><br/>
        <input type="file" name="pictures[]" /><br/>
        <input type="submit" value="Send" />

    </form>

PHP:

     <?php


$target_dir = "docs/";
$ref = $_POST['reference'];

if(!file_exists($target_dir . $ref . '/')){
    mkdir($target_dir . $ref . "/1/");
    $count = 0;
}else{
    //count the amount of folders inside docs/$ref/
    $find_folders = glob($target_dir . $ref . "/*",GLOB_ONLYDIR);
    $count = count($find_folders);
    //create new folder inside $ref/ using count+1 to make the folder increase by 1
        $new_folder = $count +1;
        mkdir($target_dir . $ref . "/" . $new_folder . "/");        
}
//If count exists then the $target_file changes to the new folder
    if($count > 0){
        $target_file = $target_dir . $ref . $new_folder . "/";  
    }else{//else use first directory
        $target_file = $target_dir . $ref ."/1/";
    }




foreach ($_FILES["pictures"]["name"] as $key => $Name) 
{
        $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
        $name = $_FILES["pictures"]["name"][$key];
        move_uploaded_file($tmp_name, $target_file . "$name");
}


?>

When i try all i get is the error: Warning: mkdir(): No such file or directory in C:\\wamp\\www\\test\\upload.php on line 8

arning: move_uploaded_file(docs/123/1/1.png): failed to open stream: No such file or directory in C:\\wamp\\www\\test\\upload.php on line 32

Warning: move_uploaded_file(): Unable to move 'C:\\wamp\\tmp\\php2E4E.tmp' to 'docs/123/1/1.png' in C:\\wamp\\www\\test\\upload.php on line 32

Any ideas on this? i'm just scratching my head over this one

I see 2 problems.

First, as you are working with windows you need to use \\ instead of / as directory separator. Best if you use the php constant DIRECTORY_SEPARATOR .

Second, in order to recursively create directories, you need the third parameter of mkdir like so

mkdir($mypath,0777,TRUE);

Putting that together you should get something like this:

$target_dir = "docs".DIRECTORY_SEPARATOR;
$ref = $_POST['reference'];

if(!file_exists($target_dir . $ref . DIRECTORY_SEPARATOR)){
    mkdir($target_dir . $ref . DIRECTORY_SEPARATOR . "1" . DIRECTORY_SEPARATOR, 0777, true);
    $count = 0;
}else{
    //count the amount of folders inside docs/$ref/
    $find_folders = glob($target_dir . $ref . DIRECTORY_SEPARATOR . "*",GLOB_ONLYDIR);
    $count = count($find_folders);
    //create new folder inside $ref/ using count+1 to make the folder increase by 1
        $new_folder = $count +1;
        mkdir($target_dir . $ref . DIRECTORY_SEPARATOR . $new_folder . DIRECTORY_SEPARATOR, 0777, true);        
}
//If count exists then the $target_file changes to the new folder
    if($count > 0){
        $target_file = $target_dir . $ref . DIRECTORY_SEPARATOR . $new_folder . DIRECTORY_SEPARATOR;  
    }else{//else use first directory
        $target_file = $target_dir . $ref . DIRECTORY_SEPARATOR . "1" . DIRECTORY_SEPARATOR;
    }
