php calculate

[dflow]

this code echoes correctly the sum but the inserted result is 0??

<?php
$TotalNumberAdults=$_POST['TotalNumberAdults'];
$TotalNumberChildren=$_POST['TotalNumberChildren'];
$TotalNumber=($TotalNumberAdults + $TotalNumberChildren); 

?><?php echo sprintf($TotalNumber);?>
<input name="TotalNumber" type="hidden" value="<?php echo sprintf($TotalNumber);?>" size="7">

when you say your inserted result is 0, do you mean into a database?  If so can I see your sql statements?

I am confused, when I test your code and change your post to a value of 2 for each the adults and children, I get a result of 4 for both the echo and the insert in your form.

 

Looks fine to me.

Read the manual on how to properly utilize sprintf

 

echo sprintf('%d', $TotalNumber);
