Multi select dropdown in plugin settings?

[pichalite]

I am working on a plugin and trying to add a multi select dropdown to the settings page in the ACP. I can select multiple values, hit save and the values are getting saved in the database and I can retrieve them back from the db. If I go to the settings page again after saving, the dropdown UI doesn't reflect the options selected based on the values in the db. Any help?

How are you handling the saving code? We recommend

nodebb-plugin-quickstart/quickstart.tpl at master · NodeBB/nodebb-plugin-quickstart

A starter kit for quickly creating NodeBB plugins. - nodebb-plugin-quickstart/quickstart.tpl at master · NodeBB/nodebb-plugin-quickstart

GitHub (github.com)

:

<script>
	require(['settings'], function(Settings) {
		Settings.load('quickstart', $('.quickstart-settings'));

		$('#save').on('click', function() {
			Settings.save('quickstart', $('.quickstart-settings'), function() {
				app.alert({
					type: 'success',
					alert_id: 'quickstart-saved',
					title: 'Settings Saved',
					message: 'Please reload your NodeBB to apply these settings',
					clickfn: function() {
						socket.emit('admin.reload');
					}
				})
			});
		});
	});
</script>

The code there should handle selects properly.

@julian I am using the same exact code. Regular select works fine. The problem is with selects with multiple option.

If I make the select multiple and just pick one option, then I can see the option selected when I come back to the settings page later. If I pick 2 or more and then come back to the page, there is no indication on the UI of which options were selected.

Any help? This is the only thing stopping me from finishing the plugin.

I reported

please keep in touch for updates

[julian]

can we get the HTML for that?

Thanks @psychobunny

<div class="form-group col-xs-12">
					    <label for="categories">Category</label>
					    <select multiple class="form-control" name="categories" title="Categories">
                           <option value="">Select a category</option>
                           <option value="1">Announcements</option>
                           <option value="2">General Discussion</option>
                           <option value="4">Comments &amp; Feedback</option>
                           <option value="3">Blogs</option>
                        </select>
</div>

This plugin works for me:

Settings.registerPlugin({
    Settings: {},
	types: ['selectMultiple'],
    use: function () {
        Settings = this;
    },
    set: function (element, value) {
        if (value.constructor === Array) {
            for (var val in value) {
                element.find('option[value=val]').attr("selected",true);
            }
        }
    },
    get: function (element, trim, empty) {
        var value = [];
        element.find('option:selected').each(function () {
            value.push($(this).val());
        });
        return value;
    }
});

With data-type="selectMultiple" added to the select tag.

@pichalite Fixed. Give latest NodeBB code a try.

[julian]

Oh, @pichalite, something to consider -- the values as saved are now JSON in the database, not comma separated (that was just the default behaviour of .toString()).

So the multiselect should save data as ['foo', 'bar', 'baz']

[pichalite]

@julian Pulled the latest code. Doesn't seem to work for me. The data is still getting saved as comma separated and I don't see the options selected after page refresh.

You may need to clear cache?

@julian Tried clearing the cache, no luck. Setup a new installation of NodeBB using master, doesn't work. Am I missing something?

What git hash are you on? git rev-parse HEAD

@pichalite I see where I went wrong, you don't have an id, but name is the correct property to check. One moment.

[julian]

@pichalite Okay, pull and try again.

[pichalite]

@julian Perfect, works now. Thank you.

@pichalite Thanks for helping make NodeBB better!
