Breaking: #64668 - Content Element mailform moved to legacy extension¶
The fallback "mailform" functionality, containing the
FORM ContentObject, the submission logic for sending mailform
and the content element (CType=mailform) has been moved to the legacy extension "compatibility6". This mailform
was available when the "Form" extension, introduced in TYPO3 CMS 4.7, was not installed.
The following options have been marked for deprecation:
$TYPO3_CONF_VARS][FE][secureFormmail] $TYPO3_CONF_VARS][FE][strictFormmail] $TYPO3_CONF_VARS][FE][formmailMaxAttachmentSize]
The following methods within TypoScriptFrontendController have been removed:
protected checkDataSubmission() protected sendFormmail() public extractRecipientCopy() public codeString() protected roundTripCryptString()
Mailform elements are missing and not rendered in the frontend anymore unless EXT:compatibility6 is loaded.
Any installation using the fallback "mailform" Content Element, the FrontendDataSubmissionController or the FORM Content Object directly will break. Additionally, any third party extension using the TypoScriptFrontendController methods directly will stop working with a fatal error.
For TYPO3 CMS 7, installing EXT:compatibility6 brings back the existing functionality. For the long term the affected installations should migrate to a different, better suited solution for sending mails and building forms.
