Need help trying to remove a array value (Customer ID) from a attribute array value in a collection
//unfollowAction
//Get Model to save data to.
$model = Mage::getModel("userprofiles/userprofiles");
$model->getCollection()->addFieldToFilter('userprofiles_id', $id);
$model->setUserprofilesId($id);
//Get Model to fetch data from
$model2 = Mage::getModel("userprofiles/userprofiles")->load($id);
//Build Array output is 123,234,345,456,
$FollowProfilesArray = array($model2->getFollowProfiles());
//Remove specified ID from array, $profile_id equals current customer ID
$remove_from_array = array_diff($FollowProfilesArray, array($profile_id,));
foreach($remove_from_array as $key => $value){
$select .= ''.$value.',';
}
//save new array to attribute value with the specified ID removed.
$model->setFollowProfiles($select);
Problem is that this code is not removing the specified ID and saving the attribute value as 123,234,345,,
Note:
$model2->getFollowProfiles() output/saved value is 123,234,345,456 etc
the code $FollowProfilesArray = array($model2->getFollowProfiles()); does not work as stated above but if it hardcode the array data to
//Works,but not ideal or relevant
$FollowProfilesArray = array(123,234,345,456,);
So is there something im missing like exploding or imploding the $FollowProfilesArray = array($model2->getFollowProfiles()); code
