hi

i'm still learning silverstripe but the documentation isn't very good for me so i have probably basic question for you

i want to add a new layer with SELECT FORM with values form database into my CMS

what is wrong ? i get empty select form

class TourPage extends Page {

static $db = array(
....
);

static $has_one = array(
....
);

function tour() {
$sqlQuery = new SQLQuery();
$sqlQuery->select = array(
'Title'
);

$sqlQuery->from = "SiteTree";

$sqlQuery->where = "ClassName = TourHolder";

$rawSQL = $sqlQuery->sql();

$result = $sqlQuery->execute()->result();
}

function getCMSFields() {
$fields = parent::getCMSFields();

....
....

$fields ->addFieldToTab("Root.Content.See Also", new DropdownField('ToursList', 'Tours',$result));

return $fields;
}

}

class TourPage_Controller extends Page_Controller {
}

You're working way too hard.

function getCMSFields()
{
$fields = parent::getCMSFields();
$fields->addFieldToTab("Root.Content.See Also", new DropdownField('ToursList','Tours',DataObject::get("Tour")->toDropdownMap()));
return $fields;
}

not sure what this is about:

function tour() {
$sqlQuery = new SQLQuery();
$sqlQuery->select = array(
'Title'
);

Stay away from using the SQLQuery object directly. Stick to the ORM.

This didn't work?

new DropdownField('Tours','Tours',DataObject::get("TourPage")->toDropdownMap());

I suppose what you really want is to create a relationship to the TourPage.

static $has_one = ('SeeAlso' => 'TourPage');

$fields->addFieldToTab("Root.Content.See Also", new DropdownField('SeeAlsoID','Tours',DataObject::get("TourPage")->toDropdownMap()));

i need help again :>

ok i have the dropdownlist and to database a put value which i chose

static $db = array(
'SeeAlsoID' => 'Text'
);

now i want to select other values form two tables which are connected by SeeAlsoID

SELECT Title, Content FROM SiteTree, TourPage WHERE SiteTree.ID = TourPage.SeeAlsoID

next i want to create some template for the query result

i create function

class TourPage extends Page {

static $db = array(
...
);

static $has_one = array(
...
}

function tour() {
...
}

function getCMSFields() {
...
}

   function SeeAlsoData(){
      $sqlQuery = new SQLQuery();
      $sqlQuery->select = array('Title', 'Content');
      $sqlQuery->from = "SiteTree, TourPage";
      $sqlQuery->where = "SiteTree.ID = TourPage.SeeAlsoID";

      // get the raw SQL
      $rawSQL = $sqlQuery->sql();

      // execute and return a Query-object
$result = new DataObjectSet();
      $result = $sqlQuery->execute();
      foreach($result as $row) {
         $title = $row['Title'];
$content = $row['Content'];
      }
      return $this->renderWith("SeeAlso");
   }

}

in SeeAlso.ss i have

<% control SeeAlsoData %>
<p>$title</p>
<p>$content</p>
<% end_control %>

in PageTour.ss i tried include template by $SeeAlso but i get "The website server has not been able to respond to your request."

Once again, you're working way too hard. You shouldn't be using SQLQuery objects, and actually, none of your code is necessary. It's all built into Silverstripe.

On TourPage.ss, all you have to do is:

<% control SeeAlso %>
$Title
$Content
<% end_control %>

I recommend you read tutorial #5 in the docs on DataObject management.

Edited: 19/01/2009 2:55am

so if i add in TourPage.php this code

static $has_one = array(
'SeeAlso' => 'SiteTree'
);

i will get relationship between the TourPage table and the SiteTree table where TourPage.ID = SiteTree.ID

and if i want to get Title from SiteTree only have to do is put this code in TourPage.ss

<% control SeeAlso %>
$Title
<% end_control %>

?

but id doesnt work

EDIT: it works :)
