Deprecation: #89331 - FormEngine legacy functions 

See forge#89331

Description 

The FormEngine supports global callback functions executed on certain interactions. Such functions were overridden and spread through some extensions which are not related to FormEngine at all.

These functions have been marked as deprecated:

  • setFormValueOpenBrowser()
  • setFormValueFromBrowseWin()
  • setHiddenFromList()
  • setFormValueManipulate()
  • setFormValue_getFObj()

The function setFormValueFromBrowseWin() is also called by ElementBrowser. Extensions not related to FormEngine are able to override this function and inject custom handling. This approach has been marked as deprecated as well.

Impact 

Calling a deprecated function will trigger a warning in the browser console.

Affected Installations 

All installations using 3rd party extensions calling any of these deprecated functions are affected.

Migration 

Some functions can be used in FormEngine context only from now on. Load the module TYPO3/CMS/Backend/FormEngine and use the according replacements:

  • setFormValueOpenBrowser() - use FormEngine.openPopupWindow() instead
  • setFormValueFromBrowseWin() - use FormEngine.setSelectOptionFromExternalSource() instead
  • setHiddenFromList() - use FormEngine.updateHiddenFieldValueFromSelect() instead
  • setFormValueManipulate() - no replacement, this is internal logic for form controls separated into according modules
  • setFormValue_getFObj() - use FormEngine.getFormElement() instead

If setFormValueFromBrowseWin() is not used within a FormEngine context, it is possible to listen to the message event.

Example code:

require(['TYPO3/CMS/Backend/Utility/MessageUtility'], function (MessageUtility) {
  window.addEventListener('message', function (e) {
    // MessageUtility.MessageUtility is correct as this is not an AMD module
    if (!MessageUtility.MessageUtility.verifyOrigin(e.origin)) {
      throw 'Denied message sent by ' + e.origin;
    }

    if (typeof e.data.fieldName === 'undefined') {
      throw 'fieldName not defined in message';
    }

    if (typeof e.data.value === 'undefined') {
      throw 'value not defined in message';
    }

    const result = e.data.value.split('_');
    const field = <HTMLInputElement>document.querySelector('input[name="' + e.data.fieldName + '"]');
    field.value = result[1];
  });
}
