1.6 Validation class can't use is_numeric as a rule

[eluser]dmorin[/eluser]
It appears that something has changed in the validation class. I used to use the native php function 'is_numeric' in the rules list and it worked fine. Now, it replaces the field with a 1 or blank depending on if it is numeric or not.

Of course, using 'numeric' works as specified in the user guide.

Could you try something for me? Could you add this into system/libraries/validation.php?

Code:

// --------------------------------------------------------------------
    
    /**
     * Is Numeric
     *
     * @access    public
     * @param    string
     * @return    bool
     */    
    function is_numeric($str)
    {
        return ( ! is_numeric($str)) ? FALSE : TRUE;
    }

and let me know if it works? If it does (it should) I'll commit this for you immediately.

Yes, that fixes it. Thanks.
