$cat = Category::all();
$sub = Subcategory::all();
return response(['cat' => $cat, 'sub' => $sub]);
you need to prepare your data to be easy to loop on it so you can get category with each related subcategory like this :-
$cat = Category::with('subCategory')->get();
so you need to add this relationship inside category model .
in this point you will get the categories with each category you will have its related sub category .

I have a table that lists the materials used to make the product. and I retrieve the prices times the quantities, then sum the results to determine the costing.
I created a SQL statement that uses SUM(td price*td current quantity). However, the outcome was incorrect.
function row_data($row_id){
$this->db->select('*,SUM(transfer_details.td_price * transfer_details.td_current_qty) AS total,trim(GROUP_CONCAT(DISTINCT stock_details.sd_wh_id SEPARATOR ",")) as whs');
$this->db->from('manufacturing_workshops');
$this->db->join('transfer_details','transfer_details.td_th_id = manufacturing_workshops.mw_transfer_id','left');
$this->db->join('maintenance_details','maintenance_details.md_id = manufacturing_workshops.mw_md_id');
$this->db->join('stock_items','stock_items.s_id = manufacturing_workshops.mw_si_id');
$this->db->join('stock_details', 'stock_details.sd_si_id=stock_items.s_id');
$this->db->where('mw_id',$row_id);
$this->db->group_by('transfer_details.td_id');
$data = $this->db->get();
return $data->result();
}
I need to return the sum of the multiplication of the td_price and td_current_qty columns.

$date = Yii::$app->request->post('date');
$timestamp = strtotime($date);
var_dump($timestamp );
error
PHP Warning – yii\base\ErrorException
strtotime() expects parameter 1 to be string, array given
you should check you post for an array in $_POST('date')
in this case you could access at the value providing an index
$timestamp = strtotime($date[0]);

I have data getting from API looks like this:
How do I can insert data to my database in my controller laravel. Can anyone help me?
Based on the image from the question, you can try some thing like this in your controller
public function insertData (Request $request) {
foreach($request->detailedHistory as $data)
{
$row = new YourModel();
$row ->column_name1 = $data['DetailedHistoryItem']['date'];
$row ->column_name2 = $data['DetailedHistoryItem']['source'];
// and so on for your all columns
$row->save(); //at last save into db
}
}
it's all about array manipulation. please have a look at this
