laravel : count(): Parameter must be an array or an object that implements Countable

Question

I'm using Laravel 5.3 and my php ver is 7.1

when i called SoftDeletes class i get that error

ErrorException in Builder.php line 1231: count(): Parameter must be an array or an object that implements Countable

this is my model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;


class Post extends Model
{

    use SoftDeletes;

    protected $dates = ['deleted_at'];

    protected $fillable = [

        'title','content','image','category_id','slug'
    ];



    public function category(){


        return $this->belongsTo('App\Category');
    }
}

and it is my controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Post;

use App\Category;

use Session;

class PostsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {



        return view('admin.posts.index')->with('posts',Post::all());

    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        $category = Category::all();

        if($category->count() == 0){

            Session::flash('info' , 'You must create at least 1 category to add a new post');

            return redirect()->back();
        }

        return view('admin.posts.post')->with('categories',$category);
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {

        $this->validate($request,[

            'title'         => 'required|max:255',
            'image'         => 'required|image',
            'content'       => 'required',
            'category_id'   => 'required'
        ]);


        $image = $request->image;

        $image_new_name = time().$image->getClientOriginalName();

        $image->move('/uploads/posts' , $image_new_name);



        $post= Post::create([

            'title'          => $request->title,
            'image'          => '/uploads/posts/' . $image_new_name,
            'content'        => $request->content,
            'category_id'    => $request->category_id,
            'slug'           => str_slug($request->title)
        ]);

        Session::flash('success' , 'You created a new post');

        return redirect()->back();



    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

and when i delete the count() function also get the same error

how can i solve this error

You'll need to look deeper, the problem is not with the code you posted. The error message should indicate a file name and line number, where `count()` is called. To help you debug this, we need to know what is being passed to `count()` and where it came from. — rickdenhaan, Dec 08 '18 at 21:38

Laravel 5.3 and my PHP ver is 7.1 is not compatible with each other Refer to this issue in the github

To solve this error you can do two things

Upgrade laravel 5.3 to laravel 5.5 refer this ( 5.3 to 5.4, 5.4 to 5.5 )
Downgrade you php to php 5.6

I changed line 1231 in C:\laragon\www\mystore\vendor\laravel\framework\src\Illuminate\Database\Eloquent

to

$originalWhereCount = !empty($query->wheres) ? count($query->wheres) : 0;

Changing the code in the vendor directory is never a good idea. - These changes will vanish once you run composer update or install command - These kinds of changes can bring you very unexpected behaviour in the application - Trust me this is not an optimal solution as it will break the code in another area ``` I personally suggest to check your laravel and php dependency and upgrade PHP/laravel which is supported. In this case. Php 5.6 is supported not PHP 7.2. ``` – Vikas Rinvi Apr 27 '19 at 10:20
In our situation, with an old project, it was our only solution until we could upgrade the php and laravel version. – Diego Galocha Aug 18 '20 at 09:11

I had the same problem with the laravel find() method returning an object and not an array. Therefore the count() method will not work. Try: Stackoverflow solution or

Post::all()->toArray();

Will return an array that will work with the count() method.

laravel : count(): Parameter must be an array or an object that implements Countable
