You can use sortBy for laravel collection for sorting by custom orders.
You can do like this:
$collection = collect($array);
$order = [1,2,3,4,5];
$collection->sortBy(function($model) use ($order){
return array_search($model->order_id, $order);
}Also, you could add an attribute accessor to your model which does the same.
public function getSortedItemsAttribute()
{
if ( ! is_null($this->item_order)) {
$order = $this->item_order;
$list = $this->items->sortBy(function($model) use ($order){
return array_search($model->getKey(), $order);
});
return $list;
}
return $this->items;
}foreach ($list->sortedItems as $item) {
// More Code Here
}If you need this sort of functionality in multiple places I suggest you create your own Collection class.
class MyCollection extends Illuminate\Database\Eloquent\Collection {
public function sortByIds(array $ids){
return $this->sortBy(function($model) use ($ids){
return array_search($model->getKey(), $ids);
}
}
}Then, to actually use that class override newCollection() in your model. In this case it would be in the ChecklistItems class:

{
return new MyCollection($models);
