MT::App::CMS::cmspresave.$type

This callback is invoked prior to a user saving an object via the Movable Type application. This callback is most often used by developers to save the state of the form/screen used to submit the entry. For example, the size of the WYSIWYG editor is “sticky,” meaning Movable Type will remember the size of the WYSIWYG editor between screens. This is accomplished through this callback. When a user submits the Edit Entry form, the callback retrieves from the form input parameters the size of the textarea and saves it for later retrieval.

Input Parameters

  • $cb - a reference to the current MT::Callback object handling this event.
  • $app - a reference to the MT::App::CMS object processing this request.
  • $obj - a reference to the MT::Object being saved.
  • $original - a reference to the original MT::Object prior to it being modified.

Return Value

None.

Example Handler

sub handler {
    my ($cb, $app, $obj, $original) = @_;
    my $height = $app->param('text_editor_size');
    # do something
}

The documentation here is incorrect about the return value. If you do not return a boolean value, then the callback will fail.
