I have a problem in adding codes in my php codes, but i have the concept of codes that i want to add in my php codes, but I don't know if it is right. Kindly check my codes thank you.
I attached my whole codes for better understanding
and here is the codes I want to add:
$query = "SELECT * FROM clt_transact WHERE clt_no = '" . $_POST . "'";
$result_no = mysql_query($query);
if(mysql_num_rows($result_no) > 0 )
$operation2_input = 0;
$query = "SELECT SUM(t.input_qty) AS operation_input FROM clt_traceability t, clt_transact p WHERE t.clt_transact_id = p.clt_transact_id AND t.operation_name 'Operation2' AND p.clt_no='" . $_POST["clt_no"] . "'";
$resultyield = mysql_query($query);
if(mysql_num_rows($resultyield) > 0)$operation2_input =mysql_result($resultyield,0,"operation2_input");
$operation2_total = $operation2_input;
I want to happen is all the input qty that the user insert in input qty textfield will sum and the result will appear in operation2_total in input_qty textfield.
I don't know how thus the result should be appear automatically in the input qty of operation2_total and if my code is correct.
