Decimal Problem

[maskme]

Hi !

I'm chking the txtbox field value after a user submits the form dat it is numeric & has just one decimal point.

if (!eregi("^{[0-9]*\.[0-9]{2,2}$",} $bkprice)) $msg = $msg. "<li>Invalid Book Price</li>";

E.g: If a person enters 23.56
Its ok, work fine! N it will take only 2 places decimal & only one decimal i.e. it should not b 23.56.34 else it will show an error

Now the problem comes whn a user does not enter a decimal value.
E.g: If a person enters just 200

then it shows error. 'coz it has to satisfy the condition.

I want any no. without decimal to b accepted. And if a no. has a decimal it should chk whether tht it has only one decimal point in it & only 2 places decimal.

Any Help would b appreciated!
Thanx in Advance
Yusuf

There's an easier way, try using is_numeric().
