Dropzone output from base and display?

Question

MySQL

1. Hello everyone, guys who worked with DropZone, tell me, I'm deducing from the display base for editing, how to make them accept DropZone, that is, I loaded them, they were displayed, how to do the same only when outputting from the database?
2. How to display loaded names in Input, that is, after a successful load, a json array was added [{"id":1,"name":"poster.jpg"}]
and after the next load it was supplemented, like this

[{"id":1,"name":"poster.jpg"},{"id":2,"name":"poster_2.jpg"}]

, as I understand it, you need to do it in the success function:
We build a check for the emptiness of the input

var input = document.getElementById('poster');

if( input.value.length == 0 ) {
   // Здесь будет первое загруженное изображение.
}
else
{
   // Если input не пустой значит изображение есть, здесь мы выполняем последующие добавление .push()
   var mass = [];
   mass.push( file.name ); // Добавляем название файла в массив
   mass = JSON.stringify( mass );
   input.val( mass );
}

Tell me what's wrong?
