This TYPO3 extension adds a custom form element "Linked checkbox" to the TYPO3 form framework. The user is able to define the link target and the link text.
Copy the extension folder to \typo3conf\ext\ , upload it via extension
manager or add it to your composer.json. Add the static TypoScript
configuration to your TypoScript template.
Open the TYPO3 form editor and create a new form/ open an existing one. Add a new element to your form. The modal will list the new custom form element "Linked checkbox". Provide a label for the checkbox and select a page you want to link to. Furthermore, you have to set a link text.
Instead of creating a new form element, the existing Checkbox form element
could have been extended. In order to provide a more complex example, the
extension creates a new element.
At the time of writing this, you have to provide a small JavaScript snippet
(see \Resources\Public\JavaScript\Backend\FormEditor\ViewModel.js). This
snippet is needed to show the custom form element in the form editor. For
TYPO3 v9 we are aiming to remove this stumbling block to smoothen the element
registration.
This exemplary TYPO3 extension was created by Björn Jacob (https://www.tritum.de). The idea was born at the TYPO3 CertiFUNcation Day 2017. The audience of my talk kindly asked for such an element. Lightheaded, I said it will not take more than 30 minutes to create such an extension. Unfortunately, I could not make it in this time. It took my nearly 1.5 hours to come up with all the code. The JS part gave me a hard time.
