numericality
Numerical input and range check.
Checks if the input is a number and within a certain range or equal to a fixed value. At the moment only integer inputs are allowed.
Arguments are is, minimum and maximum.
For example, when the input must be 42:
<input type="text" id="number" name="number" value="" />
{% validate id="number" type={numericality is=42} %}
And for a number within a certain range:
<input type="text" id="percent" name="percent" value="" />
{% validate id="percent" type={numericality minimum=0 maximum=100} %}
