SilverStripe 3.1 - Page creating & publishing from the FrontEnd

Question

for our company intranet, I created a page with a Form to create an E-Mailing from the frontend (Create a New E-Mailing Page).

The page should be Live after saving the form. I did it like this, but I think I made a mistake somewhere. Because KW1, KW2, Date and SendDate are only visible on the frontend if I go to the backend and click publish again.

public static $allowed_actions = array(
    'MailingForm'
);

public function MailingForm() {
    $date = new DateField('EndDate', 'Gültig bis');
    $date->setConfig('showcalendar', true);

    $sendDate = new DateField('SendDate', 'Versanddatum');
    $sendDate->setConfig('showcalendar', true);

    $fields = new FieldList(
        new TextField('Title', 'Title'),
        new TextField('KW1', 'Start KW'),
        new TextField('KW2', 'End KW'),
        $date,
        $sendDate
    );

    $actions = new FieldList(
        new FormAction('createMailing', 'Erstellen')
    );

    //$validator = new RequiredFields('Title');

    return new Form($this, 'MailingForm', $fields, $actions);//, $validator);
}   

public function createMailing($data, $form) {
    $member = Member::currentUser();
    $filter = new URLSegmentFilter();

    $page = new Mailing();
    $form->saveInto($page);
    $page->PublisherID = $member->ID;
    $page->AuthorID = $member->ID;
    $page->ParentID = $this->ID;
    $page->URLSegment = $filter->filter($page->Title);
    $page->writeToStage('Stage');
    $page->publish('Stage', 'Live');

    // EMAIL BEG
    $email = new Email();

    $email->setTo('mail@mail.de'); 
    $email->setFrom('intranet@mail.de'); 
    $email->setSubject('Neues E-Mailing für '.$this->Title); 

    $messageBody = "
        <p>Neues E-Mailing wurde angelegt und wartet auf Freischaltung</p>
        <p><strong>Name:</strong> {$data['Title']}</p>
        <p><strong>KWs:</strong> {$data['KW1']} - {$data['KW2']}</p>
        <p><strong>Gültig bis:</strong> {$data['EndDate']}</p>
        <p><strong>Versanddatum:</strong> {$data['SendDate']}</p>
    "; 
    $email->setBody($messageBody); 
    $email->send();
    // EMAIL END

    return $this->redirect($this->Parent()->URLSegment.'/'.$this->URLSegment.'/'.$page->URLSegment);

}

If I replace $page->writeToStage('Stage'); $page->publish('Stage', 'Live'); with $page->write() than the page isn't published if i add $page->write() to the other two than i receive this error

Can't find [Title of Page]/[Page ID] in stage Stage

Can someone help me here?

Thank you in advance

To break down the problem again

If I publish the Page with

$page->write();
$page->writeToStage('Stage');
$page->publish('Stage', 'Live');

than all data is submitted correctly but I receive the following error http://www.picbutler.de/bild/301819/erroroirpt.jpg and the page is only saved as live version. In the backend the page is than marked as "deleted from draft". So I think this is the right direction.

If I publish the Page with

$page->writeToStage('Stage');
$page->publish('Stage', 'Live');

I receive no error, the submitted data appears in the backend BUT NOT in the published version. I have to publish the Page again in the backend to make the data visible in frontend.

So any ideas how to fix this?

Answer 1

ok, a million tries later i got it! :) For everybody else who get stuck on this.

You just need to restore the live page to stage after writing

$page->write();
$page->doRestoreToStage();

That's all :)

Answer 2

Many many thanks for your two lines of codes

$page->write();

$page->doRestoreToStage();

I have been struggling with SiteTree table for a last few days,trying to write a new record to this table.

One important point is never use SiteTree class directly otherwise it won't work

eg $mySiteTree = new SiteTree(); (Bad)

Create a new page extends SiteTree() , say, Mypage

$mypage = new Mypage();
$mypage->Title = 'My Page';
$mypage->URLSegment = 'testing';
$mypage->ShowInMenus = '1';
$mypage->Version = '1';
$mypage->ParentID = '24';
$mypage->write();
$mypage->doRestoreToStage();

Enjoy!!!!
