[TYPO3-dev] TCA Backend Input form Validation

[Satish Maurya]

Hi All,

Could you please help following error in below code? this code I have
written in ext_localcong.php file and need to apply validation on TCA form
when updating the backend admin.

1. Below code display two error messages
2. After displaying the errors, data gets update into database. I need to
restrict db update if error display.

//------------------------------
if($table == 'tx_ce_featurerequest_data') {
if( $fieldArray['vote_start_date'] > $fieldArray['vote_end_date'] ) {
$message =
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Messaging\\FlashMessage',
 'Start date cannot be greater than End date.',
 'Please correct following errors:',
 \TYPO3\CMS\Core\Messaging\FlashMessage::ERROR,
 TRUE
);
\TYPO3\CMS\Core\Messaging\FlashMessageQueue::addMessage($message);
return false;
}

//--------------------

Could you please suggest anyting?
