Tinymce v6 dropzone config options - file

Question

I've created a custom dialog with a dropzone in order to upload files and images to our server. By default the dropzone renders with 'Drop an image here' / 'Browse for an image'.
As part of the tinymce editor options file_picker_type allows setting of the default dropzone and I wondered how to access these options for a stand-alone dropzone?
My tinymce options include:
tinymce.init({
file_picker_types: 'file image'
});
My upload dialog config looks something like this:
const upload_config = {
title: 'Upload files',
size: 'medium',
body: {
type: 'panel',
{
type: 'dropzone',
name: 'file_drop',
types: 'file image' //// <----- something like this???
}
]
},
buttons: [
{
type: 'cancel',
name: 'closeButton',
text: 'Cancel',
},
{
type: 'submit',
name: 'submitButton',
text: 'Upload',
buttonType: 'primary'
}
],
onSubmit: (api) => {
// handle upload here
}
};
Anybody managed to fathom this? The tinymce docs are in no way comprehensive as they simply say "A dropzone is a composite component that catches drag and drops items or lets the user browse that can send a list of files for processing and receive the result." but give no details on how to actually do that with a stand alone dropzone.
I've managed to make it all work, but this is the last hurdle.
Thanks in advance

Answer 1

Are you trying to override the default image/file upload dialog with the custom one? I'm asking because I see the file_picker_types config option. To do so, you will need to use the file_picker_callback.
If it's something else and you are not trying to override the default dialog, use this interactive example as a base. You will need to:
a) Register the custom button with a setup function:
setup: function (editor) {
editor.ui.registry.addButton('custom-upload', {
icon: 'upload',
onAction: function () {
editor.windowManager.open(upload_config)
}
})
},
b) Add this button to the toolbar via toolbar: 'custom-upload'. This way, pressing the button will open the dialog based on the upload_config variable.
c) You've made a mistake in the panel config. I guess, you forgot to create the items array at the beginning. Instead of
type: 'panel',
{
type: 'dropzone',
name: 'file_drop',
types: 'file image' //// <----- something like this???
}
]
There should be:
type: 'panel',
items: [
{
type: 'dropzone',
name: 'file_drop',
label: 'Dropzone',
}
]
I've created this fiddle as a quick demo: https://fiddle.tiny.cloud/3iiaab
P.S. The dropzone component does not support file types. But you can check the file types after they are uploaded.
