How to get WHMCS product price details by query?

If you would like to know the price details of a product in WHMCS by query,
you can use the below query.

First you have to get the currency id. It’s the Id of the currency chosen by the user.

I wrote a function named getCurrencyId to get the currency ID.

function getCurrencyId() {
    $uid = $_SESSION['uid'];
    if (empty($uid)) {
        if (!empty($_SESSION['currency'])) {
            return $_SESSION['currency'];
        } else {
            return 1;
        }
    }
    $userData = Capsule::table('tblclients')
            ->select('currency')
            ->where('id', '=', $uid)
            ->first();
    if (!empty($userData))
        return $userData->currency;
    else
	return 1;
}

Assume that we would like to know price details of the product with id = 10.
Then we have to join tables tblproducts and tblpricing on a condition
‘tblproducts.id’, ‘=’, ‘tblpricing.relid’.

$currency_id = getCurrencyId();
$pid = 10;
$product_details = Capsule::table('tblproducts')
  ->join('tblpricing', 
      'tblproducts.id', '=', 'tblpricing.relid')
  ->where('tblpricing.type', '=', 'product')
  ->where('tblproducts.id', $pid)
  ->where('tblpricing.currency', $currency_id)
  ->select('tblproducts.*', 'tblpricing.*')
  ->first();

From the result array $product_details
we can get monthly, quarterly, semiannually, annually, biennially and triennially
as given below. If no price is entered for a particular period, you will get price as -1.

$monthly_price = $product_details->monthly;
if($monthly_price != -1 ) {
   echo "monthly price is" . $monthly_price;
}
//do -1 check all of the periods.

$quarterly_price = $product_details->quarterly;
$semiannually_price = $product_details->semiannually;
$annually_price = $data->annually;
$biennially_price = $data->biennially;
$triennially_price = $data->triennially;
