I read this: https://github.com/enyo/dropzone/wiki/Set-URL-dynamically but i dont got success... :( I have 1 form...
And i send the inputs with ajax.
The aj
Another way that worked for me (accept event callback):
$('div#dropzone').dropzone({ options..., accept: function (file, done) { this.options.url = 'the url you want'; } });
