$date = Yii::$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 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.

$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 am not able to get this otp parameter in smarty because it is ommiting + sign from url.
http://test.com/index.php?otp=+AU7Og==
I have used following code but not getting value +AU7Og== of otp parameter
{$smarty.get.otp|escape:html}
{$smarty.get.otp|escape:htmlall}
It's not a smarty problem. In the query of a URL, + represents a space. You'll have to encode the plus sign if you want to use it as part of a string parameter
