Re: Problem creating TreeMultiselectField to look up Page
27 March 2009 at 11:36am Last edited: 27 March 2009 11:37am
Hi Mo
This is exactly what i am want to achieve and this all works fine for the first page I edit and select the check boxes for. However it's not updating the database table with any other page edits.
It looks like it's saving the changes made on the first edit of the first page and then not saving any other changes to any other pages
I get exactly the same results with the code you put.
Which version of SilverStripe are you using? I'm doing this on 2.3
Thanks

Hooray, I found a solution. It's not the most user friendly if you have lots of content
I changed the TreeMultiselectField to CheckboxSetField using the following:
function getCMSFields() {
$fields = parent::getCMSFields();
$pageList = DataObject::get('SlimJimsContentPage');
$fields->addFieldToTab("Root.Content.LinkedPages",new CheckboxSetField('SlimjimsLinkedPages','Select all related pages to appear in the right column', $pageList));
return $fields;
}And this seems to be updating the database OK. Am still not sure why the TreeMultiselectField wasn't updating the database table for more than one page. If I find an answer I'll update

Hi,
I have the exact same problem as Aaron - i have used the code from Mo's post.
I can select and save the checked pages for one page.
When i go to another page, i do get the dropdown, everything seems to be saved, but it is not, so when i reload the CMS the field of the new page is blank.In Page.php i have:
class Page extends SiteTree {
...
public static $many_many = array(
'BotLinksList' => 'Page'
);
public function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Content.Main', new TextField( 'TitleDescription', "Page Description"));
$fields->addFieldToTab('Root.Content.Links', new TreeMultiselectField( 'BotLinksList', 'Bottom links', 'SiteTree' ));
return $fields;
}
...My db now has a Page_BotLinksList table, with the fields ID, PageID, SiteTreeID, ChildID
Any help is appriciated, thx.

It seems there is a bug somewhere in TreeMultiselectField, isn’t it? Has somebody submitted a ticket to Trac? If there’s no bug (and I think it’s probably us that are not understanding how it works), maybe a developer will explain how to use it! ;-)

I'm not sure if this is a bug or not but I'v found that the $many_many 'key' should be the same as the 'class' for a TreeMultiselectField or ManyManyComplexTableField within a Page::getCMSFields().
For example, this works;
class ClientType extends Page {
static $many_many = array(
'ServiceTree' => 'ServiceTree'
);
function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab("Root.Content.Main", new TreeMultiselectField("ServiceTree", "Related Services", "ServiceTree"));
/**
OR;
$rcTablefield = new ManyManyComplexTableField(
$this->owner,
'ServiceTree',
'ServiceTree',
array(
'Title' => 'ArticleTitle'
));
$rcTablefield->setPermissions(array('show'));
$rcTablefield->setPageSize('150');
$fields->addFieldToTab('Root.Content.RelatedContent', $rcTablefield );
**/
}
}
class ServiceTree extends Page{
// A class similar BlogTree which gets extendedstatic $many_many = array(
'ClientTypePages' => 'ClientType'
);
}But it appears to work differently when customising the SiteConfig ie;
class CustomSiteConfig extends DataObjectDecorator {
function extraStatics() {
return array(
'many_many' => array(
'FooterLinks' => 'SiteTree'
);
}
public function updateCMSFields(FieldSet &$fields) {
$fields->addFieldToTab("Root.Main", new CompositeField(
new TreeMultiselectField("FooterLinks", "Footer Links", "SiteTree")
));
}And I think DOM requires that the 'key' be different to the 'class' ?

@All, Thanks for sharing.
@Aaron, Did you got any solution to make this work with TreeMultiselectField custom page list?
my code is working great with "CheckboxSetField". But not working with TreeMultiselectField in case of custom page list "NewsPage".
My working Code with "CheckboxSetField":
------------------------------------------------------------
public static $many_many = array(
"FeaturedArticle"=>"NewsPage",
);public function getCMSFields() {
$fields = parent::getCMSFields();
$pageList = DataObject::get('NewsPage');
$f = parent::getCMSFields();
$f->addFieldsToTab("Root.Content.FeaturedArticle", array(
new CheckboxSetField("FeaturedArticle", "Choose a your featured article:", $pageList),
));return $f;
}
------------------------------------------------------------Though when I use "TreeMultiselectField " this with "SiteTree" it works.
working Code with SiteTree is :
public static $many_many = array(
"FeaturedArticle"=>"SiteTree",
);public function getCMSFields() {
$f = parent::getCMSFields();
$f->addFieldsToTab("Root.Content.FeaturedArticle", array(
new TreeMultiSelectField("FeaturedArticle", "Choose a your featured article:", "SiteTree"),
));
}Any idea why it is not working with "NewsPage" class in TreeMultiselectField ?
