Hi,
I have two models, 'Group' and 'Section'.
There are 5 sections, and each group can have any combination of sections. So, I've successfully set up a relationship with $_has_many and $_many_many and a joining table.
I tried implementing a multiselect on my form using a similar technique to other one-to-many relations, but I'm a bit puzzled as to how to save and repopulate properly. I've managed to save the relation once using the example from the Docs page, but it wouldn't re-save!
$sections = Input::post('sections');
$count=0;
foreach ($sections as $section_id) {
$group->sections[$count] = Model_Section::find($section_id);
$count++;
}
I've populated the select like so:
$selected = $group->sections;
$selected_sections = array();
foreach ($selected as $section) {
$selected_sections[] = $section->id;
}
$view->set_global('selected',$selected_sections);
And the form:
<?php echo Form::select('sections[]', $selected_sections, $sections, array('class' => 'span6','multiple'=>'multiple')); ?>
If someone could point me to an example that'd be great. Not sure if there's a much easier way that I'm missing?
Sorry about formatting - my editor doesn't seem to be working.
Thanks, Rich
