Dropzone image upload options not working :(
Question
Im trying to build a drag and drop image upload but dropzone options dont work and I dont know if im doing it the right way.
I would love to set up the following options:
Upload only one file (multiupload parameter)
Possibility to remove that file (addremovelink?)
Max file size of 2mb (maxfilesize)
Can you help me please?
here is the code:
<html>
<head>
<title></title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="dropzone.js" type="text/javascript"></script>
<link href="css/basic.css" rel="stylesheet" type="text/css" />
<link href="css/dropzone.css" rel="stylesheet" type="text/css" />
</head>
<body>
<script type="text/javascript">
$(document).ready(function(){
$("#uploadme").dropzone({
paramName: 'photos',
url: 'upload.php',
dictDefaultMessage: "Drag your images",
clickable: true,
enqueueForUpload: true,
maxFilesize: 1,
uploadMultiple: false,
addRemoveLinks: true
});
});
</script>
<form action="upload.php" class="dropzone">
<div id="uploadme" class="fallback">
<input name="file" type="file" multiple />
</div>
</form>
</body>
</html>

Just add before Jquery call
Dropzone.autoDiscover = false;
and remove the action from the <form> . That will disable the auto discover function so you can specify all the options for your form.
This is what your code should look like:
<html>
<head>
<title></title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="dropzone.js" type="text/javascript"></script>
<link href="css/basic.css" rel="stylesheet" type="text/css" />
<link href="css/dropzone.css" rel="stylesheet" type="text/css" />
</head>
<body>
<script type="text/javascript">
$(document).ready(function(){
Dropzone.autoDiscover = false;
$("#uploadme").dropzone({
paramName: 'photos',
url: 'upload.php',
dictDefaultMessage: "Drag your images",
clickable: true,
enqueueForUpload: true,
maxFilesize: 1,
uploadMultiple: false,
addRemoveLinks: true
});
});
</script>
<form action="" class="dropzone">
<div id="uploadme" class="fallback">
<input name="file" type="file" multiple />
</div>
</form>
</body>
</html>

In my situation I had to use the vanilla JS Dropzone Class instantiation and put the Dropzone.autoDiscover = false; outside of the $(document).ready function.
html:
<form id="image-upload" action="/upload" class="dropzone" method="post" name="file"></form>
javascript:
<script>
Dropzone.autoDiscover = false;
$(document).ready(function() {
var myDropzone = new Dropzone('form#image-upload',{
maxFiles:12,
acceptedFiles: 'image/*',
dictInvalidFileType: 'This form only accepts images.'
});
});

maxFilesize: 2,
uploadMultiple: false,
addRemoveLinks: true,
maxFiles: 1,
autoProcessQueue: false
You will need to add in a button or event handler to allow for processing of the previewed file, if you let it autoProcessQueue you don't have time to decide if you want the file or not unless you add an event handler at the "process" event.
$("#uploadme").dropzone.processQueue()
