ErrorException Trying to get property 'kode_buyer' of non-object

Question

Im trying to populate my dropdown with data from my database

Heres my Model :

public function getBuyer($slug = false)
{
    if ($slug == false) {
        return $this->findAll();
    }

    return $this->where(['kode_divisi' => $slug])->first();
}

Controllers :

public function produksi()
{
    $data = [
        'main' => 'buyer/produksi',
        'title' => 'List Produksi',
        'hasil' => $this->buyerModel->getbuyer()
    ];
    return view('template/template', $data);
}

And View :

<div class="content-wrapper">
<!-- Content Header (Page header) -->
<div class="content-header">
    <div class="container-fluid">
        <div class="row mb-2">
            <div class="col-md-10 col-sm-10 col-xs-10 mx-auto">
                <div class="card">
                    <div class="card-header bg-info" style="text-align: center;">

                        </form>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

And it gave my this error:

ErrorException Trying to get property 'kode_buyer' of non-object

it says that this line is the cause of the error:

echo "<option value='".$row->kode_buyer."'>".$row->nama_buyer."</option>";

Is there a way to fix this? i already try some alternate way, but it lead to the same error

Im using Codeigniter 4 BTW.

Answer 1

as by your comment, your data looks like this:

array(3) { ["main"]=> string(14) "buyer/produksi" 
           ["title"]=> string(13) "List Produksi" 
           ["dataku"]=> object(stdClass)#87 (5) { 
                ["kode_buyer"]=> string(5) "IK001" 
                ["nama_buyer"]=> string(13) "Ik Collection" ["pic"]=> string(13) "Wanda Purnomo" 
                ["no_tlp"]=> string(1) "0" 
                ["alamat"]=> string(6) "Cimahi" 
           } 
         }

This means kode_buyer is not at array's top level, but a nested object of dataku, therefore $row->kode_buyer gives you an error, as it doesn't exist there. You need to access kode_buyer that way:

$row["dataku"]->kode_buyer
