A TYPO3 extension to manage workshops (or events, seminars, ...).

Build Status StyleCI

What does it do?

tx_workshops provides functionality for managing and displaying workshops, and ships with signup functionality.

This extension and its features are developed on demand. If you're missing a feature, we'd be happy to accept some code for it. Alternatively, contact us if you'd like to sponsor a feature and we'll happily integrate it for you.


Workshops requires some basic TypoScript to work properly. Include the static extension template into your template and you're set. If you don't include the static TypoScript, TYPO3 will not recognize the table mappings required for tx_workshops to work.


Feature toggling

In order to keep everything as minimalistic as possible, advanced features are disabled by default. Have a look at the extension configuration inside the extension manager to enable/disable features.

Registration field validations

The only validation which is always run on registrations is extbase's EmailAddressValidator. If you need more validations, you're free to configure them through TypoScript. Example:

plugin.tx_workshops.settings.registration.validation {
    firstName {
        10.validator = NotEmpty
        20.validator = StringLength
        20.options.minimum = 5
    additionalFields {
        membershipCode {
            10.validator = NotEmpty

A list of validators together with valid options for them is available in the API documentation.

Email delivery

Delivering an email takes some time. In order to optimize frontend response times on e.g. registrations, emails can be delivered through a scheduler task / cron job in the background. For this, you have to set the according TypoScript configuration option. If this is an issue for you or for your hosting provider (sadly, this can be the case), you should configure workshops to deliver directly. Have a look at the TypoScript file inside Configuration/TypoScript, which lists all possible settings.

Attention: Have a look at the issues, as there is currently a problem when delivering emails through cron when using multiple languages.

iCalendar export (ICS)

To provide an ICS file containing workshop dates, set up a separate PAGE TLO responding to a certain typeNum, and call the export plugin there. An example:

icsExport = PAGE
icsExport {
    config {
        disableAllHeaderCode = 1
        xhtml_cleaning = none
        admPanel = 0
        metaCharset = utf-8
        additionalHeaders = Content-Type:text/calendar;charset=utf-8
        disablePrefixComment = 1
    typeNum = 1234
    10 = USER
    10 {
        userFunc = TYPO3\CMS\Extbase\Core\Bootstrap->run
        vendorName = NIMIUS
        extensionName = Workshops
        pluginName = Exports

Don't forget to have the following configuration parts set in your TypoScript template:

plugin.tx_workshops.settings.export.iCalendar {
    // These two values are used as PRODID, which is a required property.
    businessName = Your business name
    productName = Your product name

// The 2-char language code is also required for a valid PRODID
config.language = en

Requesting a page with ?type=1234 will now respond with an ICS file containing all upcoming dates. You can also pass workshop to it to narrow down results. Example:

<f:link.action pluginName="Exports" controller="Exports" action="iCalendar" arguments="{workshop: workshop}" additionalParams="{type: 1234}">ICS</f:link.action>


In order to deliver confirmation emails, make sure to have a working scheduler, and register the appropriate extbase tasks. The following tasks are currently provided:

  • notification:registrationConfirmationCommand - Delivers notification mails to workshop attendees.


Email templates are freely configurable through fluid, you'll find them in Resources/Private/Templates/Notifications.

Email configuration

Make sure that your TYPO3 instance is properly configured for email delivery. Check your install tool / LocalConfiguration.php for valid information in the [MAIL] section. There's also a report module checking for this. Alternatively, you can set required information for delivery through TypoScript.


Workshop Detail views automatically add the correct openGraph meta tags to the <head> of the TYPO3 Page. This behaviour can be disabled by setting plugin.tx_workshops.settings.openGraph = 0.

The twitter username and the facebook app ID can be set using the following TypoScript and / or Constants path:

plugin.tx_workshops.settings.openGraph {
    twitter.username = @MyUsername
    facebook.app_id = MyAppid
