jsonRPCClient Error with php variables

Question

I am trying to run the following code

$betamount=$_POST['bet']; 
$litecoin->move($myusername,Admin,$betamount);

but it will not work. it does however work when i replace $betamount with an actual number ie

$litecoin->move($myusername,Admin,0.2);

or

$betamount=0.1; 
$litecoin->move($myusername,Admin,$betamount);

any ideas on whats going wrong ? the $_POST['bet'] is defiantly a number because i have tried multiplying in php and it all works fine.

Answer 1

Fixed this now, All you have to do is change it to this

floatval(trim()) ie ...    $betamount=floatval(trim($_POST['bet'])); 

for numbers

and this

and just trim()  ie ... $litecoinaddr=trim($_POST['address']); 

for strings

Answer 2

Admin isnt a variable so its a string.

Strings should be in quotes so it should be.

$litecoin->move($myusername,'Admin',$betamount);
