RSVPMaker 0.8 Released

Here are a few improvements early users of RSVPMaker have been asking for:

Version 0.8

  • Added type parameter for shortcode so you can display only events tagged with “featured” or another event type using [rsvpmaker_upcoming type=”featured”] (see the featured events on the home page of this site)
  • Added ability to set RSVP start date as well as deadline for RSVPs
  • If signing up workers or volunteers for specific timeslots, you can now specify the duration of the timeslots in one-hour increments
  • Cleaned up “Event Dates, RSVP Options” box in editor, moving less commonly used parameters to the bottom.
  • Added a Tweak Permalinks setting (a hack for a few users who have reported “page not found” errors, possibly because some other plugin is overwriting the RSVPmaker url rewrite rules).
  • Tested with WP 3.1 release candidate

To-Do List for Improvements

These are mostly things I got as requests from other people who have tried RSVPMaker and are looking for some extra features. Let me know if these are on your list, or if you see other areas for improvement, so I will know what to prioritize.

  • Ability to set both a start date and a deadline for accepting RSVPs. Currently, I only provide a start date.
  • When soliciting signups for specific timeslots (for example, volunteers at an event), allow variable lengths for the timeslots (currently fixed at one hour).
  • For multi-day events with RSVPs, the option of letting people sign up for one or more days but not necessarily all. So for a 3-day event, we might provide checkbox for those who only want to sign up for two days out of three.
  • Some system for approving RSVPs, where there is some criteria for acceptance. I got this request a few weeks ago but am unsure how it should work, so not giving it a high priority.
  • A way to specify different RSVP forms for different event types. Might offer this as a set of cookbook guidelines for people who want to do special customizations, rather than as a core part of the plugin.

The trick with addressing some of these requests will be doing so without cluttering things up too much for those whose needs are more basic.

I’m planning to move some of the more complicated options that only apply in special cases to a separate section of the control panel for setting RSVP parameters.

The event type category I provide isn’t really being used for anything now. I’m thinking that the shortcodes for displaying listings should have a way of designating that you only want to list the events in the featured category or some other category.

Also want to revise the recurring event editor to let you specify how far ahead you want to project the dates for the events you are setting up.

How to Add Events with RSVPMaker

This is a brief illustrated tutorial on the RSVPMaker event editor and the primary options it provides.

Here’s how you set up a basic event, with just a headline, event description and date and time set.

A basic event - headline, description, date and time

And here’s what it gets you:

A basic event

Here, we’re specifying both a start time and a duration, so that the system will display both a start time and an end time.

You can also set up a multi-day event with a common headline and description for a weekend camping trip or week-long conference.

If you want to collect RSVPs, you need to check the Collect RSVPs checkbox and specify an email address for whoever needs to receive notifications when someone completes the form. You can also view a report of everyone who has RSVP’ed.

There are also options you can use to:

  • Set a deadline for RSVPs (leave this blank otherwise)
  • Set a maximum number of participants (leave it at zero for no limit)
  • Prompt users to sign up for one-hour timeslots, an option intended for use staffing volunteer events. A future release may allow you to set the time interval for the volunteer timeslots, but right now it’s fixed at one hour.
Setting RSVP Parameters

If you view an event listing, you will now see an RSVP Now button at the end of the listing. You can also send out email invitations that include this button to prompt a response (See How to Post and Email an Event, which explains the related ChimpBlast plugin for use with MailChimp email broadcast accounts).

Event listings include an RSVP Now! Button

Click the button or the headline, and you’ll be taken to a view of the single event with the RSVP Form displayed.

Clicking button or other link to single event display brings up the RSVP Form

The RSVP editor will also display options for setting prices for online payments if you have PayPal enabled. See How to Set Up PayPal with RSVPMaker for details.

Utility for Posting Recurring Events

I just published RSVPMaker version 0.7.5, which updates the utility for adding a series of recurring events. This includes the ability for software to calculate the dates based on a schedule like “Second Tuesday of the month.”

The idea is that you can create a basic event listing for several months into the future, with boilerplate details on your meeting location and other common parameters such as whether an RSVP will be required. You can then go back and edit or update those listings as needed.

This alternate editor does not include the rich text editor you get when you edit a single post, but you can include your own HTML in the description body. The RSVP options at the bottom of the screen are the same ones displayed on the main event editor screen.

Recurring Event Editor

If I make use of the ability to specify a schedule such as “Second Tuesday,” I get a series of dates loaded into the editor. I change the dates as necessary (for example, to account for schedule changes around holidays), enter my details, and submit.

The results:

I also provide a Multiple Events editor, which is even more basic — just a quick way of editing a bunch of events at once. Again, you can always go back and enhance the listings as needed.

Improvements to RSVP Report

I’ve upgraded the RSVP Report to be a little neater, include a function for printing reports, and add an option for deleting entries (including spam entries or test entries).

RSVP Report, showing the listing of upcoming events and how many RSVPs for each:

Listing of responses for a specific event:

Note the new “Format for Printing” link, which pulls up a version of this report that opens in a new window with no links or WordPress branding / navigation showing.

Clicking the delete link under a name brings up a confirmation screen. If there were guests associated with the entry, you’ll be asked if you want to delete them, too.

If you want to create fancier reports, you can do so by overriding the rsvp_report function (See: Changing the RSVP Form, Other Customizations)

Changing the RSVP Form, Other Customizations

Note: RSVPMaker 2.5 makes more advanced customization of the RSVP form available from within the administration console, which may eliminate the need for some code-level customization.

RSVPMaker includes a mechanism for allowing you to add custom functions or override the some of the default functions included with the plugin. Specifically, you can override any of the functions defined in rsvpmaker-plugabble.php. You do this by adding your own rsvpmaker-custom.php file to the plugins directory (the directory above the rsvpmaker folder). My distribution includes a sample rsvpmaker-custom.php file but it will not be activated until you move it to the new location.

Essentially, this lets you plug in your own functions within my plugin. The idea is to provide some freedom to customize, without losing the benefit of upgrades to the core rsvpmaker code.

Modifying the event_content function

More extensive customizations are possible by overriding the event_content function, although this is a longer, more complex function. If you open the rsvpmaker-plugabble.php file, you will see the functions are wrapped with if(!function_exists(‘function_name’) ).

If you copy the function definition for event_content into your custom.php file, you will be able to modify the function as necessary for your purposes.

Creating an Event Template

When a single event is displayed, the standard single post template may tend to cause confusion because it juxtaposes the posting date with the event date. This is particularly a concern for post templates that feature the publication date prominently at the top of the post.

You can avoid this problem by adding a single-rsvpmaker.php file to your theme. WordPress will load this instead of the single.php template for an event post type.

A sample single-rsvpmaker.php file for the Twentyten theme is included with the RSVPMaker download, but you must copy it from the plugin folder to the theme folder to get it to take effect. Note that this file may not work with themes other than Twentyten without modification.

Most themes include a single.php file that you can modify to remove (or de-emphasize) the code that outputs the post publication date. I also recommend removing the code that outputs the comments template because people tend to be confused by having two forms on the page (the RSVP form and the comment form).

Updated 12/29/2010 to reflect change in file naming (single-rsvpmaker.php rather than single-event.php).

Translators Wanted

I’m planning to introduce support for translation in the next update. So far, I’ve got interest in French and Danish. I’m a mono-linguistic American, so my contribution will be limited to tagging words and phrases for translation and looking for collaborators who can do the actual translating.

The process is outlined at

Update 12/29/2010: I’ve finished flagging most of the elements in the user interface that I thought might need to be translated and have added them to the file rsvp.pot in the plugins/rsvpmaker/translations subdirectory of the latest release. This is the “catalog” file that you load into a tool such as POEdit to translate words and phrases such as “RSVP Now!” into whatever makes more sense in a given language.

Send me your translations to be included with a future release, and I will be happy to credit your contribution.

Some Users Reporting Page Not Found Errors

A few users who have tried the RSVPMaker plugin report problems with getting 404 page not found errors when they try to follow a link to one of these entries. Let me know if you experience this issue, as I’m trying to track down the cause. It seems to work fine for most people, but I may be running into some kind of clash with other plugins that manipulate the WP rewrite rules object.

One website manager I’ve been working with has it functioning correctly on one site she manages, but not another. Very puzzling.

Update: 12/29/2010: I think I’ve now resolved this issue by changing some of the code that sets up the custom post type and sets the rewrite rules.
