Trying to access array offset on value of type null

Well, the error must show more than just this right?

yes ,i already install 7.4 how can i use 7.3

Can you show code that caused the error, maybe some of us wants to check our 7.4 install to see if we also get the error. It will help narrow it down. Also as @bobbybouwmann mentioned, more of the error.

I use array's often in php and I have php 7.4, but no array problems yet.

ignition error page

Illuminate\Foundation\Bootstrap\HandleExceptions::handleError :42
app/Http/Controllers/LinksController.php:42

my code

use Debugbar;

use Theme;

use MetaTag;

use Request;

 

class LinksController extends HomeController

{

    public function index(){

        $isuser = user_logged_in();

        $user = User::where('id', $isuser->id)->where('status', 1)->first();

        $totalLinks = UserLinks::where('user_id', $isuser->id)->count();

        $qlinks = array();

        $lnks = UserLinks::where('user_id', $isuser->id)->orderBy('id', 'DESC')->get();

        foreach($lnks as $link){

            $post = Posts::where('id', $link->post_id)->first();

            $category = Categories::where('id', $post['category'])->first();

            $qlinks[$link->id] = $link;

            $qlinks[$link->id]['post_title'] = $post['title'];

            $qlinks[$link->id]['post_image'] = $post['image'];

            $qlinks[$link->id]['post_link'] = $post['link'];

            $qlinks[$link->id]['post_category'] = $category['name'];

            $qlinks[$link->id]['post_category_slug'] = $category['slug'];

            $qlinks[$link->id]['post_tagline'] = $post['tagline'];

        }

Have you used the browser developer tools to see what's going on, also dd at a couple of places as needed to ensure you are getting expected results.

Also check your variables: https://wiki.php.net/rfc/notice-for-non-valid-array-container

Edit: I tested this https://laracasts.com/discuss/channels/guides/paginate-collection-simple-example-guide bottom example with some null values, no problem. I think (not sure however) you are getting a null key.

Which one is line 42?

try

            $qlinks[$link->id] = $link;

            $qlinks[$link->id] = array();   // extra line to initialise sub-array

            $qlinks[$link->id]['post_title'] = $post['title'];
