[rhodarose]

Good day!

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:

<?php
$rexist = 0;
if($_POST["clt_no"])
{
   $opname = $_POST["opname"];
   $inqty = $_POST["inqty"];
   $outqty = $_POST["outqty"];
   
   $totalarr = count($opname) - 1;
    for($ctr=0; $ctr < $totalarr; $ctr++)
        {
        $inqty[$ctr] = (float) $inqty[$ctr];
        $outqtyqty[$ctr] = (float) $outqty[$ctr];
        
         $query = "INSERT INTO clt_traceability (operation_name, input_qty, clt_transact_id) VALUES ('" . $opname[$ctr] . "',  '" . $inqty[$ctr] . "', '" . $outqty[$ctr] . "', '" . $clt_transact_id . "')";
        $result = mysql_query($query);
        }   
        
    $query = "SELECT * FROM clt_transact WHERE  clt_no = '" . $_POST["clt_no"] . "'";
    $result_no = mysql_query($query);
        if($result_no)
            {
            if(mysql_num_rows($result_no) > 0 )
            {
            $clicking_input = 0;
            $clicking_total = 0;
            
            $query = "SELECT t.input_qty AS clicking_input FROM clt_traceability t, p WHERE t.clt_transact_id = p.clt_transact_id AND t.operation_name '02 Clicking' AND p.clt_no='" . $_POST["clt_no"] . "'";
            $resultyield = mysql_query($query);
            if($resultyield)
                {
                    if(mysql_num_rows($resultyield) > 0)$clicking_input =mysql_result($resultyield,0,"clicking_input");
                }
          /*  $query = "SELECT SUM(t.input_qty) AS clicking_input FROM clt_traceability t, clt_transact p WHERE t.clt_transact_id = p.clt_transact_id AND t.operation_name '02 Clicking' AND p.clt_no='" . $_POST["clt_no"] . "'";
            $resultyield = mysql_query($query);
            if($resultyield)
                {
                    if(mysql_num_rows($resultyield) > 0)$clicking_input =mysql_result($resultyield,0,"clicking_input");
                }*/
            $query = "SELECT operation_name FROM clt_traceability t, clt_transact c WHERE t.operation_name = '02 Clicking Total' AND t.clt_transact_id = c.clt_transact_id";
            $result = mysql_query($query);
            if($result > 0)
            {           
            $clicking_total = $clicking_input;
            //pano automatic mag eecho o mag aappear ung sum ng inqty sa inqty ng clicking total
            }
            }
    }
}
$rexist = 0;
?>

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.

Thank you

I have 5 operation name: operation1,operation2,operation2_total,operation3,operation4,operation5. As you notice I have a operation2_total

How can I add the input qty of operation2 and the result will be appear in input_qty of operation2_total.

Thank you
