I have a query that returns a collection object like so:

                [wasRecentlyCreated] => 
            )

    )

  )

In my view im iterating through each and showing the status_category value - what im trying to accomplish is to check if a specific status_category value does not exist then to add it to the end. I have tried doing: $categories->prepend('test', 'status_category');

but that doesnt add it like the object above and therefore my view will throw an error. Any ideas on this?

  • So, if status_category does not exist then you want to show a default value. Am I understanding it right? Commented May 19, 2020 at 4:57
  • Yes if Test is not part of the list of status_categories then i want to add it Commented May 19, 2020 at 20:18

Reset to default

You need to use the laravel collection map function for set value in object key value.

$categories = $categories->map(function ($item, $key) {
     $item->status_category = "test"; 
     return $item;
});

You can achieve via

1) Laravel Collection map()

$labTestRequests = $labTestRequests->map(function($labTestRequest){
    if(!isset($labTestRequest->status_category)) {   // checking if a key exist
        $labTestRequest->status_category = "default";
    }
    return $labTestRequest;
});

2) Using a simple null coalesce operator i.e. ??. What it does is if a given variable does not exists or is null then use the given default instead. In your view you can write like this

$labTestRequest->status_category ?? 'default'
