Forms, objects and how to write to many_many relations
30 September 2007 at 3:48am
Along with my problem
http://www.silverstripe.com/silverstripe-development/flat/5780I'm having another probably stupid issue.
How do I write to a table that is in a many_many relationship with the main object I'm writing to?
So suppose I have in my form-processing function:$tip = new Tip();
$tip->props = $data['props']
...In one of my forms I have a checkboxset with the name of Categories[].
My class Tip can have multiple categories, so in Tip I have:static $many_many = array(
'Categories' => 'Category',
);Now in the formprocessing function I can access the category-array
foreach($data['Categories'] as $cat)
{
$tip->Category = $cat;// this is probably wrong!!!!!
}But how do I set this? This should write to tip_categories table, but obviously setting $tip->Category is not the way to do it...
?

Issue seems to be solved automatically when I use
form->saveInto();
However, none of the Longitude/latitude data from the Mapping module seems to be saved then...
what seems logical...
