Re: Summing array indexes.

Thanks for every ones help. I just used a bunch of control structures and issest's to add it up. Not pretty but works. if (isset($data['order_product_amount_0'])) { $data['order_product_total'] = number_format($data['order_product_amount_0'], 2, '.', ''); } if (isset($data['order_product_amount_1'])) { $data['order_product_total'] = number_format($data['order_product_total'] + $data['order_product_amount_1'], 2, '.', ''); }

foreach ($orders as $data) { $total = 0; foreach ($data as $key => $val) { if (strpos('order_product_amount', $key) === 0) $total += (float)$val; } $data['order_product_total'] = number_format($total, 2, '.', ''); }

Not a direct answer to your question (don't worry, I hate it when people do this to me too), but one thought I had was to have all of the products ordered as their own array. [0] => array(15) { ["order_date"] => string(8) "09-01-08" ["order_products"] => array(2) { [0] => string(5) "10.00" [1] => string(5) "20.00" } ["order_total_price"] => string(0) "" } In this case, it would be trivial to write a foreach loop on the 'order_products' array to calculate the total. Otherwise, run a foreach over the array, looking for keys which begin with order_product_price_ and, when found, grab the price and add it to order_total_price.

Any help would be greatly appreciated. array(5) { [0] => array(15) { ["order_date"] => string(8) "09-01-08" ["order_product_price_1"] => string(5) "10.00" ["order_product_price_2"] => string(5) "20.00" ["order_total_price"] => string(0) "" } [1] => array(19) { ["order_date"] => string(8) "09-01-08" ["order_product_price_1"] => string(5) "25.00" ["order_product_price_2"] => string(5) "15.00" ["order_total_price"] => string(0) "" } Like this. array(5) { [0] => array(15) { ["order_date"] => string(8) "09-01-08" ["order_product_price_1"] => string(5) "10.00" ["order_product_price_2"] => string(5) "20.00" ["order_total_price"] => string(0) "30.00" } [1] => array(19) { ["order_date"] => string(8) "09-01-08" ["order_product_price_1"] => string(5) "25.00" ["order_product_price_2"] => string(5) "15.00" ["order_total_price"] => string(0) "40.00" } Tom Shaw php.coder@tx.rr.com ------=_NextPart_000_004B_01C90EAF.FA964EB0--
