The EntryModel you have has a sectionId property you can set. i.e.
$entry = new EntryModel();
$entry->sectionId = 1;
$saveIt = craft()->entries->saveEntry($entry);
Note that there are other properties you'll need to set for it to pass validation. So if, if $saveIt
is false after calling saveEntry($entry)
, then call $entry->getErrors()
to get an array of validation errors to fix.
