Question

I use the following code to prefil a field with an amount from a database.

$amount = db_result(db_query('SELECT amount FROM {table} WHERE nid = %d', $fid));

$node->edit_user_fid = $amount;

If the query doesnt find anything it just shows empty. How can I get the value to be 0 if theres no results?

Answer 1

$node->edit_user_fid = ($amount) ? $amount : 0;

Or also writeable as

if (!$amount) {
    $node->edit_user_fid = 0;
}

or if you’re sure that $amout is numerical (and it should be), use

$node->edit_user_fid = intval($node->edit_user_fid);
