php wont give download link feedback after upload done - php

Question

i'm trying to get DropzoneJS to work, i got far but it seems i've got a problem i can't solve.
so basicly what i want is to upload a file and get a download link back within the same page.
so i added this code to my index.php:
<form action="index.php" class="dropzone" id="my-awesome-dropzone"></form>
and the php code into the index.php:
<?php
include('config.php');
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$dirname = uniqid();
mkdir( $filedir.'/'.$dirname);
mkdir( $filedir.'/'.$dirname.'/file');
copy("template/d.php", "d/$dirname/index.php");
copy("template/dl.php", "d/$dirname/dl.php");
preg_match('/\.([a-zA-Z0-9]+?)$/', $_FILES['file']['name'], $matches);
if(in_array(strtolower($matches[1]), $accepted)) {
if($_FILES['file']['size'] <= $maxsize) {
$newname = ($_FILES['file']['name']);
// file name encryption
//$newname = md5_file($_FILES['file']['tmp_name']).'.'.$matches[1];
move_uploaded_file($_FILES['file']['tmp_name'], $filedir.'/'.$dirname.'/file/'.$newname);
$linkurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '/', $_SERVER['PHP_SELF']).'#'.$newname;
$imgurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '/', $_SERVER['PHP_SELF']).$filedir.'/'.$dirname.'/file/'.$newname;
$alt = $_POST["alt"];
$dlurl = 'http://'.$_SERVER['HTTP_HOST'].preg_replace('/\/([^\/]+?)$/', '/', $_SERVER['PHP_SELF']).$filedir.'/'.$dirname;
print '<h2>Picture Uploaded Successfuly!!!!</h2> <p id="codes">
<img src="'.$imgurl.'" height="300" alt="Uploaded Picture" >
<label for="codebb">BBCode:</label>
<input type="text" id="codebb" value="[URL='.$siteurl.'][IMG]'.$dlurl.'[/IMG][/URL]" onclick="javascript:this.focus();this.select();" readonly="true" /><br />
<label for="codehtml">HTML Code: </label>
<input type="text" id="codehtml" value=\'<a href="'.$siteurl.'"><img src="'.$dlurl.'" alt="'.$alt.'" />&lt/a>\' onclick="javascript:this.focus();this.select();" readonly="true" /><br />
<label for="codedirect">Direct Link:</label>
<input type="text" id="codedirect" value="'.$dlurl.'" onclick="javascript:this.focus();this.select();" readonly="true" /></p>';
echo ".$newname";
} else
print '<p>Sorry, Max Picture size is 10Mb</p>';
}
}
?>
when i upload the file the php works and the file is uploaded successfully into its folder so the php is working.
my problem now is why dont i get the print from the php script.
fully working script:
http://37.34.62.131/test/uploader%201.0/
not working NEW script:
http://37.34.62.131/test/
i think it has something to do with the uploader because my old script uses a submit button and my newer version is using a automatic submit.
i very appreciate your time!
