basic ad 2 ints from a db

[makatak88]

hello, still very new at this but here goes.

on the page that posts the form i have a hidden echo like so.

echo "<input type='hidden' name='price' value='$row[price]' />";

 

on the page that it posts to i have

 

$first_number = $dbh->quote($_REQUEST['price']);
$second_number = 20;
$sum_total = $first_number + $second_number;

$direct_text = 'The two variables added together = ';

print ($direct_text . $sum_total);

 

I get 20 as the result. any ideas?

 

also a couple more notes that may help:

 

datatype of price is int in db

if i echo out $first_number i get '45' not 45

if i try $newnumber = (int)$first_number;

echo $newnumber i get 0

 

cheers guys

Why are you quoting the price as if it were about to go into a database? Because it's not about to go into a database.

at this point its the only way i know to pass that value to the next page. Im learning.

Well... you don't need it.

$first_number = $_REQUEST['price'];
$second_number = 20;
$sum_total = $first_number + $second_number;

$direct_text = 'The two variables added together = ';

print ($direct_text . $sum_total);
