Conflict between GiveWP and The Events Calendar Eventbrite Tickets plugins

[benlk]

This issue has been reported through https://givewp.com/priority-support/ and https://support.theeventscalendar.com/submit_ticket , but I thought I should also submit it here.

User Story

Copy-pasting from INN/umbrella-inndev#57:

With the following plugins active on WordPress 5.0.1:

$ wp plugin list --status=active
+----------------------------------------+--------+--------+---------+
| name                                   | status | update | version |
+----------------------------------------+--------+--------+---------+
| give                                   | active | none   | 2.3.1   |
| the-events-calendar                    | active | none   | 4.7.2   |
| the-events-calendar-eventbrite-tickets | active | none   | 4.5.6   |
+----------------------------------------+--------+--------+---------+
$ wp plugin list --status=active-network
+------+--------+--------+---------+
| name | status | update | version |
+------+--------+--------+---------+

When using Give WP to create a new donation form, the options in GiveWP's custom "Donation Form Options" meta box are not saved. This is the box in its default state:

If I change the selected option on any of those radio buttons and press "Save draft" or "Publish", after the editor reloads, the options are forgotten.

If I then wp plugin deactivate the-events-calendar-eventbrite-tickets, and refresh the page, the meta box shows the options I had selected when I hit save.

If I then wp plugin activate the-events-calendar-eventbrite-tickets, the form returns to its default state.

Here's a list of things that are saved, which are not affected by this bug:

• post title
• post excerpt
• post slug
• post author
• post featured image

Which is to say: this only affects the GiveWP form data, as far as I can tell.

Are there any confounding issues?

Perhaps confounding this issue is that the Eventbrite "Migrate events" prompt is appearing in this editor and in all admin screens. The "Migrate events" button has been pressed, multiple times. It has not gone away.

Expected Behavior

I expect that the Donation Options metabox will display the information saved in the database, whether or not other plugins are active.

Bug Type

• This bug describes functionality that once worked as expected in version X.X.X.
• This bug describes functionality that never worked as expected.
• I am not sure whether this functionality ever worked as expected.

Steps to Reproduce

1. Install and activate the Give plugin, The Events Calendar, and The Events Calendar Eventbrite Tickets plugins.
2. For Eventbrite Tickets, it may be necessary to create an Eventbrite account and synchronize the plugin with the Eventbrite account in order to trigger the persistent "Migrate Events" banner.
3. From the Dashboard, click Donations > Add Form
4. Make changes to the "Donation Form Options" meta box so that it is not in its default state.
5. Click the "Save Draft" or "Publish" buttons.
6. Observe that the "Donation Form Options" meta box has reverted to its default state.
7. In a new tab or via the command line, deactivate the the-events-calendar-eventbrite-ticket plugin.
8. Refresh the form edit page. Note that the "Donation Form Options" meta box now displays the options that were initially saved.
9. In a new tab or via the command line, activate the the-events-calendar-eventbrite-ticket plugin.
10. Refresh the form edit page. Note that the "Donation Form Options" meta box now displays the default options instead of the options that were initially saved.

This happens under WordPress 4.9.9 and 5.0.1, in the https://github.com/INN/inn/ custom theme and in the Twenty Seventeen stock theme. It happens with a lot of plugins active, but it also happens with just these three plugins active.

@benlk Thanks for the detailed report. We are in contact with The Events Calendar team to see if we can find out what's happening here.

My first impression based on the behavior you've described when deactivating the Eventbrite plugin is that this may be more of an issue with loading Give settings rather than saving them. I say this because your changed options are reflected properly when the Eventbrite plugin is deactivated, which suggests the settings were saved. If the Give settings were not being saved, then you would always see the default options when the form editor loads.

One way to confirm this would be to check the wp_give_formmeta table in your database to see if your changed settings are reflected in the database.

We'll update this issue once we learn more.

Closing as duplicate of #3815 which was commented on by Modern Tribe stating they're taking care of the incompatibility on their end.
