Just because the file is 0 bytes doesn't mean your template isn't working. var_dump() the contents of $data and see if there's anything in it. If there is, then your problem is in the file_put_contents() function.

It's probably easier to test the rendering using a function in your controller.. like:

public function pageflip(){
   return $this->renderWith('PageFlipXML);
}

Then you should be able to open yoursite.tld/page/pageflip to get the xml output (for testing or direct usage in flash).

When i hit save in the DOM i see this for a short second.

string(0) ""

Redirecting to http://www.url.nl/admin/EditForm/field/FlyerPaginas/item/18/edit?ctf[FlyerPaginas][start]=0&ctf[FlyerPaginas][per_page]=10&ctf[FlyerPaginas][showall]=0&ctf[FlyerPaginas][sort]=&ctf[FlyerPaginas][sort_dir]=&ctf[FlyerPaginas][search]=&ctf[FlyerPaginas][filter]=&ctf[FlyerPaginas][view]=... (output started on /public/sites/www.url.nl/mysite/code/Flyer.php, line 62)

line 62 = var_dump ($data);
So string(0) "" means there's nothing rendered?

Ok it is giving me a nice page WITH xml content

<book plugins="anchors, backgroundsounds, batchpages, bookmarks, console, gallery, help, javascript, keyboardnavigation, links, navigationbar, options, overlays, pdflinks, print, slideshow, swfaddress, titles">
<foreground>
   </foreground>

<chapter>

<page>
<img src="/assets/Uploads/abcdef.jpg"/>
</page>

<page>
<img src="/assets/Uploads/abcdef1.jpg"/>
</page>

<page>
<img src="/assets/Uploads/abcdef2.jpg"/>
</page>

<page>
<img src="/assets/Uploads/abcdef3.jpg"/>
</page>

<page>
<img src="/assets/Uploads/abcdef4.jpg"/>
</page>

<page>
<img src="/assets/Uploads/abcdef5.jpg"/>
</page>

<page>
<img src="/assets/Uploads/abcdef6.jpg"/>
</page>
</chapter>
</book>

When i tried this:

   protected function onAfterWrite(){
    parent::onAfterWrite();

      $data = $this->renderWith('PageFlipXML');   
      $ourFileName = "/public/sites/www.url.nl/pageflip/megazine/megazine.mz3";
      $fh = fopen($ourFileName, 'w+') or die("Can't open file");
      fwrite($fh, $data);
      fclose($fh);
   }

it does write something.. 452 bytes file with the content:

<book plugins="anchors, backgroundsounds, batchpages, bookmarks, console, gallery, help, javascript, keyboardnavigation, links, navigationbar, options, overlays, pdflinks, print, slideshow, swfaddress, titles">
<foreground>
   </foreground>

<chapter>

<page>
<img src=""/>
</page>

</chapter>
</book>

So i seems it isnt processing the template correctly?

When i go to the public function url:

www.url.nl/Flyer/pageflip

i do get all src's in the img tags..
How do i get the correct template data to the file?

thx!

Make sure FlyerPaginas is a function of your Page class, not the controller. Because the $this pointer in onAfterWrite isn't the controller, but just the page class (therefore you can't use any functions from the controller).

no change in the file write process.. still get a 0bytes file.

what am i doing wrong?

There must be a way to create a xml file with a onafterwrite() using a template. What code do you use?

<?php

class Flyer extends Page {

   static $has_many = array (
      'FlyerPaginas' => 'FlyerPagina'
   );
   
   public function getCMSFields() {
$fields = parent::getCMSFields();
$manager = new FileDataObjectManager(
$this,
'FlyerPaginas', // relation name
'FlyerPagina', // class name of the DataObject
'Image', // name of the file relation in the DataObject
array(
          'Title' => 'Title',
         // 'Comment' => 'Comment',
       ), // headings
'getCMSFields_forPopup' // name of the function for the popup fields

);

   $fields->removeFieldFromTab('Root.Content.Main','Content');
   $fields->addFieldToTab('Root.Content.Images', $manager);
return $fields;
}
   public function megazine(){
    return $this->renderWith('PageFlipXML');
   }   

}

class Flyer_Controller extends Page_Controller {

}

class FlyerPagina extends DataObject {

   static $db = array (
      'Title' => 'Text',
   //   'Comment' => 'HTMLText',
   );
   static $has_one = array (
      'Image' => 'Image',
      'Flyer' => 'Flyer'
   );

   public function getCMSFields_forPopup() {
      $fields = new FieldSet();
      //$fields->push(new TextField('Title'));
      //$fields->push(new SimpleTinyMCEField('Comment'));
      $fields->push(new FileUploadField('Image','Upload files'));
      return $fields;
   }
   
   protected function onAfterWrite(){
    parent::onAfterWrite();
      $data = $this->renderWith('PageFlipXML');
      file_put_contents('/public/sites/www.url.nl/pageflip/megazine/PageFlipXML.mz3', $data);
   }
   

}

template code:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE book SYSTEM "http://www.megazine3.de/megazine2.dtd">

<book plugins="zoom, keyboardnavigation, navigationbar, swfaddress"
lang="en"   
pagewidth="567" pageheight="567"
   errorlevel="ERROR"
   zoomminscale="0.5" zoommaxscale="4.0"
   zoomsnap="0.5, 0.75, 1.0, 1.5, 2.0, 3.0, 4.0"
   zoomsteps="2"
   dragrange="20"
   maxloaded="32"
   qualitycontrol="true"
   thumbscale="0.5"
   searchmethod="client"
   cornerhint="true"
   pagethickness="0.2"
   shadows="0.3"
   searchclear="false"
   startpage="1"
   centercovers="false"
   pageoffset="0">

<!-- With zoomstep= "0.05" these zoom steps are achieved: 1.0 - 2.0 - 3.0 - 4.0 - ... 19.0 - 20.0 - 21.0
   reason: the span (zoommaxscale-zoomminscale) is devided into 1/zoomstep (i.e. 20) intervals
   So span*zoomstep=1.0, which results in a nice step size of 1.0-->

Obviously, the onAfterWrite method should be in your Flyer page.. Or you leave it in FlyerPagina (if you want to write/update the file whenever a FlyerPagina is saved), but then your onAfterWrite method must look like this:

protected function onAfterWrite(){
   parent::onAfterWrite();
   if($this->FlyerID){
      $data = $this->Flyer->renderWith('PageFlipXML');
      file_put_contents('/public/sites/www.url.nl/pageflip/megazine/PageFlipXML.mz3', $data);
   }
}

and if file_put_contents doesn't work on your system, then use the fwrite function..

Update
You should always check if there's a Flyer.. so I updated the onAfterWrite function above..
