Direct Mail

It would also help, if i could choose, when the content page is rendered into a directmail:
a) at time of using the directmail-wizard
b) at time of the sending of the mails (in that case the tt_news will me visible though its starttime)

The Case B would make it possible to coordinate the starttime of a content object and the sendtime of directmails.
Would be a great feature

Another solution would be an auto-update of the dmail DB record field "mailContent" at the time of mass-sending.

if found the possibility to
unset($TCA['tt_content']['ctrl']['enablecolumns']['starttime'])

as desribed in : http://typo3.org/documentation/document-library/tutorials/doc_tut_templselect2/0.0.1/view/1/3/

But how can i restrict the unsetting to a special page?
(The documentation shows only an example to change the process of the whole system)

the content rendering is still done by TYPO3. direct_mail reads only the rendered page by calling the page through getURL-function (t3lib_div).

changed the core function enableFields of class.t3lib_page.php to check the typoscript config variable:
config.disableFields if set to 1:
you can use config.disableFields=1 in tssetup to prevent starttime checks.

i changed the core code on a local project, which is not a good solution of course. i will try to write an extension which makes use of XCLASS or similar, when i find the time. would be great to hear some feedback before i start to. if someone likes to contribute to this, i could open a forge project.

i attach the code, where i just inserted the following statement:
&& $GLOBALS['TSFE']->config['config']['disableFields']!=1)

h1. The attached code:

if (is_array($ctrl['enablecolumns'])) {
if (!$this->versioningPreview || !$ctrl['versioningWS'] || $noVersionPreview) { // In case of versioning-preview, enableFields are ignored (checked in versionOL())
if ($ctrl['enablecolumns']['disabled'] && !$show_hidden && !$ignore_array['disabled']) {
$field = $table.'.'.$ctrl['enablecolumns']['disabled'];
$query.=' AND '.$field.'=0';
}
if ($ctrl['enablecolumns']['starttime'] && !$ignore_array['starttime'] && $GLOBALS['TSFE']->config['config']['disableFields']!=1) {
$field = $table.'.'.$ctrl['enablecolumns']['starttime'];
$query.=' AND ('.$field.'<='.$GLOBALS['SIM_ACCESS_TIME'].')';
}
if ($ctrl['enablecolumns']['endtime'] && !$ignore_array['endtime']) {
$field = $table.'.'.$ctrl['enablecolumns']['endtime'];
$query.=' AND ('.$field.'=0 OR '.$field.'>'.$GLOBALS['SIM_ACCESS_TIME'].')';
}
