How to limit user selection in ManyManyComplexTableFiled
3 June 2011 at 5:16pm
I have the following ManyManyComplexTableField, which basically form a many to many relationship that allows user to pick number of pages as recommended reading for a given page. Is there a way I can enforce a business rule into this, say user may not select more than 5 pages as recommended reading. Need a way to disable the checkbox I would thought. Any pointer would be deeply appreciated. Cheers.
$tablefield = new ManyManyComplexTableField(
$this,
'MyRegionPages',
'Page',
array(
'Title' => 'Page Name',
'BoldIntroduction' => 'Bold Introduction'
),
'getCMSFields_forPopup',
"SiteTree.ID != $this->ID AND SiteTree.ParentID=$this->ParentID",
'Sort'
);$tablefield->setPermissions(array(
));$fields->addFieldToTab( 'Root.Content.FurtherReadings', $tablefield );
