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} %}
