I have lots of number field let say num1, num2 ... Now I am looking for way I can apply a set of validation on all field rather than writing same validations multiple times.

Here is set of two validation for requiredString and Number check

<validators>
        <field name="num1">
            <field-validator type="requiredstring">
                <message>Field cannot be left blank</message>
            </field-validator>

            <field-validator type="regex" short-circuit="true">
                <param name="expression"><![CDATA[^[0-9]+$]]></param>
                     <message>Not a valid Number</message>
             </field-validator>
        </field>

</validators>

Validations are per-field. Why use a string for a number field, though? – Dave Newton Nov 24 '12 at 18:33
If I remove requiredstring then it will not be handled by number check only. main problem is can I use a single validation code for multiple fields. – Anoop Nov 24 '12 at 18:39
As I said, validations are per-field. You could always write a custom validator. – Dave Newton Nov 24 '12 at 19:40
