Create an admin interface to upload images and videos

• [ ] Authentication
• [x] Upload via drag and drop
• [x] Upload folders?
• [ ] Copy&paste images
• [ ] Image processing - see #44
• [ ] WYSIWYG editor for content

Step 1: Research which libraries we can use for this

Uploads via Dropzone.js

The cool thing is that Dropzone.js uploads files instantly, without a need for submitting the surrounding form (and we could start processing them directly via the functionality implemented in #46 - when the post is ready, so are the images!). However, that also we don't know what to attach these images to.

Unassigned uploads

Files from the dropzone within the create form upload their files to a global place (/image/@uploads).

When files are successfully uploaded, hidden input elements with the file names are created, which are then submitted along with the form. The remove button will not only delete the uploads from the server, but also remove the hidden input element.

Assign uploads

After uploading, on the server side, these uploads are then moved to the created element's storage directory.

First implementation

// Set up dropzone
const $upload = document.querySelector('#upload');
const uploads = new Dropzone($upload, {
  url            : '/api/entries/uploads',
  acceptedFiles  : 'image/jpeg,image/png,image/webp,video/mp4,video/mpeg,video/quicktime',
  addRemoveLinks : true,
  dictRemoveFile : 'Entfernen',
  accept         : function(file, done) {
    for (let i = 0; i < this.files.length - 1; i++) {
      if (this.files[i].name === file.name) return done('Existiert bereits: ' + file.name);
    }
    done();
  }
});
uploads.on('success', file => {
  const $field = document.createElement('input');
  $field.type = 'hidden';
  $field.name = 'uploads[]';
  $field.value = file.name;
  $upload.appendChild($field);
});
uploads.on('removedfile', file => {
  if ('success' === file.status || 'existing' === file.status) {
    $upload.querySelectorAll('input[type="hidden"][name="uploads[]"]').forEach($e => {
      if ($e.value === file.name) $e.remove();
    });
    fetch('/api/entries/uploads/' + encodeURIComponent(file.name), {method: 'DELETE'});
  }
});

// Populate uploads
fetch('/api/entries/uploads')
  .then(res => res.json())
  .then(files => {
    for (const file of files) {
      uploads.displayExistingFile(
        {name: file.name, size: file.size, status: 'existing'},
        '/image/' + file.path + '/' + encodeURIComponent(file.name)
      );
      uploads.files.push(file);
      uploads.emit('success', file);
    }
  })
;
