php - warning : creating default object from empty value in cakephp -

-

i working on cakephp 3.2

i have function find product types if exists

if ($product['product_type'] != null) {    $getproducttype = $this->producttypes->find()      ->where(['title like' => '%'.$product['product_type'].'%'])      ->first();     debug($product['product_type']);   // not empty    debug($getproducttype);            // shows 'id' => 1 in array    debug($getproducttype->id);        // shows 1     if (!empty($getproducttype)) {       $p->product_type_id = $getproducttype->id;           // line 11       $p->subcategory_id = $getproducttype->subcategory_id;       $p->category_id = $getproducttype->category_id;        return $this->savenewbulkproduct($product, $p->category_id, $p->subcategory_id, $p->product_type_id);    } }

but giving warning as

creating default object empty value on line 11

edit 2 output of print_r($getproducttype)

app\model\entity\producttype object  (     [id] => 3     [category_id] => 1    .... )

i think no need declare $p , not set property , value in $p, can pass values of $getproducttype object mentioned below.

if ($product['product_type'] != null) {    $getproducttype = $this->producttypes->find()      ->where(['title like' => '%'.$product['product_type'].'%'])      ->first();    debug($product['product_type']);   // not empty    debug($getproducttype);            // shows 'id' => 1 in array    debug($getproducttype->id);        // shows 1    if (!empty($getproducttype)) {       return $this->savenewbulkproduct($product, $getproducttype->category_id,  $getproducttype->subcategory_id, $getproducttype->id);    } }
