How to limit value or length of number field?

altracka

I would like to limit a number field to a reasonably small value. I would prefer to limit the value to 1000, but would also be happy to limit the length to 3. maxlength works if the type is text, but it has no effect if the type is number- it lets me type any length of input, for example 9999999999.

var editor = new $.fn.dataTable.Editor({
      table: containerId,
      display: 'bootstrap',
      fields: [
            { label: 'good', attr: { maxlength: 3 } },
            { label: 'bad', attr: { type: "number", maxlength: 3 } },
      ],
});

Just use a validator on the server.

Field::inst( 'number' )
    ->validator( function ( $val, $data, $opts ) {
        if ( $val > 1000 ) {
            return "must not exceed 1000";
        }
        return true;
    } ),

You you can also do client side validation if you prefer that:

See also this SO thread which notes that maxlength is ignored by the browser for type=number.
