short validator

Description

Field Validator that checks if the short specified is within a certain range.

Parameters

You can either use the min / max value or minExpression / maxExpression (when parse is set to true) - using expression can be slightly slower, see the example below.

Warning Do not use ${minExpression} and ${maxExpression} as an expression as this will turn into infinitive loop!

Examples

    <!-- Plain Validator Syntax -->
    <validator type="short">
        <param name="fieldName">age</param>
        <param name="min">20</param>
        <param name="max">50</param>
        <message>Age needs to be between ${min} and ${max}</message>
    </validator>

            <param name="min">20</param>
            <param name="max">50</param>

    <!-- Field Validator Syntax with expression -->
    <field name="age">
        <field-validator type="short">
            <param name="minExpression">${minValue}</param> <!-- will be evaluated as: Short getMinValue() -->
            <param name="maxExpression">${maxValue}</param> <!-- will be evaluated as: Short getMaxValue() -->
            <message>Age needs to be between ${min} and ${max}</message>
