Dropzone Js Uploads Only Two Files When Autoprocessqueue Set To False

Are you experiencing a situation where Dropzone.js, an excellent library for managing file uploads, only uploads two files even though you have set the "autoProcessQueue" property to false? Don't worry, this is a common issue that many developers face when working with Dropzone.js. Let's dive into why this might be happening and how we can solve it.

Dropzone.js is a powerful JavaScript library that provides an easy way to handle file uploads in web applications. The "autoProcessQueue" property in Dropzone.js determines whether files should be uploaded automatically as soon as they are added to the drop zone or not. When set to false, it allows you to handle when and how files are uploaded manually.

If Dropzone.js is only uploading two files even though "autoProcessQueue" is set to false, the most likely reason is that Dropzone.js has an internal limit set to the number of files that can be uploaded at once. By default, Dropzone.js limits the number of parallel uploads to 2. This means that only two files will be processed at a time, even if you have more files in the queue.

To overcome this limitation and allow Dropzone.js to upload more than two files when "autoProcessQueue" is set to false, you can increase the value of the "parallelUploads" option. This option specifies how many files can be uploaded simultaneously. By setting "parallelUploads" to a higher number, you can upload more files concurrently.

Here's an example of how you can configure Dropzone.js to upload more than two files with "autoProcessQueue" set to false:

Dropzone.options.myDropzone = {
  autoProcessQueue: false,
  parallelUploads: 5, // Change this to the desired number
  // Other options
};

var myDropzone = new Dropzone("#my-dropzone");

In the above code snippet, we set the "parallelUploads" option to 5, allowing Dropzone.js to upload up to 5 files simultaneously. Adjust the value of "parallelUploads" based on your requirements and the server's capacity to process multiple uploads concurrently.

By increasing the "parallelUploads" option, you should now be able to upload more than two files with Dropzone.js even when "autoProcessQueue" is set to false. Remember to test your implementation thoroughly to ensure that it meets your application's requirements and works as expected.

In conclusion, the limitation of Dropzone.js uploading only two files with "autoProcessQueue" set to false can be overcome by adjusting the "parallelUploads" option. By increasing the number of simultaneous uploads, you can efficiently handle multiple file uploads in your web application. Keep experimenting and exploring the capabilities of Dropzone.js to enhance your file upload functionality seamlessly.
