Problem creating TreeMultiselectField to look up Page
14 March 2009 at 4:11am Last edited: 14 March 2009 4:11am
Hi
In the Page object I need TreeMultiselectField that will allow the users to select more than one Page which can then be listed in the template as a link list.
I've tried setting up an many_many relationship without success.
When I put the following code in the database refuses to rebuild
public static $many_many = array(
'LinkPages' => 'Page'
}Is there a better way of doing this?

What you'll need to do is define the end of the relationship as well. So, because a Page can have many of itself both ways, you'll want something like this:
public static $many_many = array(
'LinkedPages' => 'Page'
);public static $belongs_many_many = array(
'BelongingPages' = 'Page'
);Kinda confusing, but that should solve your database build problem.

I am having an issue with this also. For me "/dev/build" works fine and everythjing looks normal, but whenever I try to save the data in the admin area, I get an "Error saving page" error.
Currently my code is in a class "YourWorldHub":
public static $many_many = array(
'Box1Links' => 'YourWorldHub'
);public static $belongs_many_many = array(
'BelongingPages' => 'YourWorldHub'
);function getCMSFields() {
$fields = parent::getCMSFields();$fields->addFieldToTab( 'Root.Content.CopyBoxes', new TreeMultiselectField( 'Box1LinksID', 'Possible Links', 'SiteTree' ) );
return $fields;
}I also tried:
public static $many_many = array(
'Box1Links' => 'SiteTree'
);Anyone have any ideas?
Ta,

Right, I have it working now:
public static $many_many = array(
'Box1Options' => 'SiteTree'
);function getCMSFields() {
$fields = parent::getCMSFields();$fields->addFieldToTab( 'Root.Content.CopyBoxes', new TreeMultiselectField( 'Box1Options', 'Possible Links', 'SiteTree' ) );
return $fields;
}For some reason SilverStripe has issue with a $many_many that has a key with "Links" in it? :s
Hope this helps someone.

Hi Sean and Mo
Thanks for your help with this.
I've made these changes and still no luck.
When I navigate to the page I am able to select multip options from the drop down and when I click publish it appears to save correctly. But when I navigate away and come back it hasn't saved the selections.
On further investigation it will only save one link from one page and is not saving the others.

Is your $many_many item still referencing Page? Or is it now SiteTree?
When I tried to referencing Page my script failed.

Hi Mo
I restructured my object model as thought it might be that and it sort of followed the examples.
I now have a SlimJimsContentPage where I've put
public static $many_many = array(
'SlimjimsLinkedPages' => 'SiteTree'
);And this lets me select and save the linked pages for one page only.
In the Page.php I've put
public static $belongs_many_many = array(
'SlimjimsBelongingPages' => 'SlimJimsContentPage'
);However, it only saves the checked pages for one page. For all others I get a message saying it's saved them but it hasn't.

Hi Aron,
I just reread your original post, I am not sure why you are using $belongs_many_many?
In order to get a list of pages (that is selected in the cms) to render on a page, all I do is:
In mysite/code/Page.php
class Page extends SiteTree {
public static $db = array();
public static $many_many = array(
'LocationList' => 'SiteTree'
);function getCMSFields() {
$fields = parent::getCMSFields();$fields->addFieldToTab( 'Root.Content.Main', new TreeMultiselectField( 'LocationList', 'Box Questions', 'SiteTree' ) );
return $fields;
}};
class Page_Controller extends ContentController {
public function init() {
parent::init();
}
}Then in my themes/themename/templates/layout/Page.ss
<ul>
<% control LocationList %>
<li><a href="$Link">$Title</a></li>
<% end_control %>
</ul>Is this not what you want to achieve?
