adding two fields together to get a result.

Minnie Mouse 17 Feb, 2008

hi i am trying to pass the result of adding two number fields together into the database.

i successfully did this into the email and the thankyou page but i cant get it written to the database.

here is the code i put in the onsubmit before email.

<?php 
$totalhrs= $_POST['Prog1_Hours']+$_POST['Prog2_Hours']+$_POST['Prog3_Hours']+$_POST['Prog4_Hours']+$_POST['Prog5_Hours'] ;
?>

<input type="hidden" name="Total_Homeo_Hours" value="<?php echo $totalhrs; ?>">

it returns a 0 result...
i am no expert at this stuff so i hope i am close anyway :-)

Hi MM,

Do you have a database field for 'total hours' - I guess that you do and it's called 'Total_Homeo_Hours' and the value is set to $_POST['Total_Homeo_Hours'].

To write the value you need

<?php 
$_POST['Total_Homeo_Hours'] = $_POST['Prog1_Hours'] + $_POST['Prog2_Hours']+ $_POST['Prog3_Hours'] + $_POST['Prog4_Hours'] + $_POST['Prog5_Hours'];
?>

As the form input is hidden you can probably leave the value as value="".
