Hi everyone,

i just want a bit of pointing in the right direction. I have a site that is selling golfing breaks. One of the pages is a hotel view page. On this hotel page I need to be able to...

1. Add a content block (fine - part of the normal Page type)
2. Add images to a slideshow using a simple upload form (in the CMS)
3. Add related hotels (i.e. hotels near by) by selecting what is essentially another page with the same type.
4. Add a thumbnail for the hotel (so it will appear in the related hotels section) with a tiny abstract (20 words or something)

This is what I think I need to do...

Extend the page controller
Use uploadify

Any ideas would be great! thanks,

Hi,

I'm no PHP expert, but i would do something like the following.

I would create a new page type HotelViewPage

1. Use Content as you say
2. Create a Dataobject with a has many relation for the images / content in the slideshow (http://doc.silverstripe.org/sapphire/en/tutorials/5-dataobject-relationship-management the student mentor section)
3. Add a many many relation for the related hotels (same URL as above but the section "Project - Module relation")
4. Just add an image field to the related hotels Page / Dataobject

Hope this helps

BTW: No need for Uploadify if using Dataobjects instead.

Thanks... i have come up with this code...

Hotel.php

<?php
class Hotel extends DataObject
{
   static $db = array (
      'Name' => 'Text',
      'LocationCity' => 'Text',
      'Lat' => 'Text',
      'Long' => 'Text'
   );

   static $has_many = array(
'HotelImages' => 'HotelImages'
);

   function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab( 'Root.Content.Main', new TextField( 'Name' ) );
$fields->addFieldToTab( 'Root.Content.Main', new TextField( 'LocationCity' ) );
$fields->addFieldToTab( 'Root.Content.Main', new TextField( 'Lat' ) );
   $fields->addFieldToTab( 'Root.Content.Main', new TextField( 'Long' ) );
      return $fields;
}
}
class Hotel_Controller extends Page_Controller {}

HotelImages.php

<?php
class HotelImage extends DataObject {

   static $db = array(
'Alt' => 'Text',
);
   
   static $has_one = array (
      'Attachment' => 'File',
      'MyHotelImage' => 'Hotel'
   );

public function getCMSFields_forPopup()
   {
      return new FieldSet(
         new TextField('Alt'),
         new FileIFrameField('Attachment')
      );
   }
}

HotelPage.php

<?php
class HotelPage extends Page
{
   static $has_many = array (
      'Hotels' => 'Hotel'
   );

   public function getCMSFields()
   {
      $f = parent::getCMSFields();
      $manager = new ImageDataObjectManager(
         $this, // Controller
         'Hotels', // Source name
         'Hotel', // Source class
         'Attachment', // File name on DataObject
         array(
            'Alt' => 'Alt'
         ), // Headings
         'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
         // Filter clause
         // Sort clause
         // Join clause
      );
$f->addFieldToTab("Root.Content.HotelImages",$manager);
return $f;
   }
}

Which is a mash of code found on your mentioned tut, plus http://doc.silverstripe.org/old/modules:dataobjectmanager

All that happens when I try to add the page type is I get an error "There has been an error"

I am unsure where I went wrong.

In previous code I got a list of images added to the page fine, but I wanted to get the relationship right so I could extend with multiple tabs, i.e. one for images, then one for related other hotels.

Any help would be great!

thanks

You Hotel class is extending Dataobject, but you also have
class Hotel_Controller extends Page_Controller {}
not sure if you can do that.

I would make the hotels pages, as i dont think you can manage a many many relation in a Dataobject in the CMS.

Enable debugging to get some more usefull error messages, add the following to mysite/_config.php:
// Debug mode - remember to set to live before going live!
Director::set_environment_type( 'dev' );

great thanks... getting somewhere!

now with the related hotels... this is where I am confused, as it has a many_many relationship with itself? I.e. a hotel can have many related hotels?

static $many_many = array(
'Hotels' => 'Hotel'
);

is that right?

Sorry, i think i will need to see the relevant code now: post to http://www.sspaste.com/ or somewhere.

The tutorial should explain how this is done - not sure i can do a better job :-)

Hi

i went with a bit of a work around...

<?php
class ResourcePage extends Page
{
   static $db = array(
'HotelName' => 'Text',
'Lat' => 'Text',
'Long' => 'Text'
);
   
   static $has_many = array (
      'Resources' => 'Resource'
   );
   
   public static $has_one = array(
      'RelatedLink1' => 'SiteTree',
      'RelatedLink2' => 'SiteTree',
      'RelatedLink3' => 'SiteTree',
      'HotelThumb' => 'File'
   );
   
   public function getCMSFields()
   {
      $fields = parent::getCMSFields();
      $fields->addFieldToTab( 'Root.Content.Main', new TextField( 'HotelName' ) );
$fields->addFieldToTab( 'Root.Content.Main', new TextField( 'Lat' ) );
$fields->addFieldToTab( 'Root.Content.Main', new TextField( 'Long' ) );
      $fields->addFieldToTab( 'Root.Content.Main', new FileIFrameField( 'HotelThumb' ) );
      
      $treedropdownfield1 = new TreeDropdownField("RelatedLink1ID", "Choose a hotel that wish to link to:", "SiteTree");
      $treedropdownfield2 = new TreeDropdownField("RelatedLink2ID", "Choose a hotel that wish to link to:", "SiteTree");
      $treedropdownfield3 = new TreeDropdownField("RelatedLink3ID", "Choose a hotel that wish to link to:", "SiteTree");
      
      $fields->addFieldToTab("Root.Content.RelatedHotels", $treedropdownfield1);
      $fields->addFieldToTab("Root.Content.RelatedHotels", $treedropdownfield2);
      $fields->addFieldToTab("Root.Content.RelatedHotels", $treedropdownfield3);
      
      
      $manager = new ImageDataObjectManager(
         $this, // Controller
         'Resources', // Source name
         'Resource', // Source class
         'Attachment', // File name on DataObject
         array(
            'Description' => 'Description'
         ), // Headings
         'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
         // Filter clause
         // Sort clause
         // Join clause
      );
      $fields->addFieldToTab("Root.Content.Hotel Images",$manager);
      return $fields;
   }
}

seems to work well!
