Thanks for this!

I get "Wrong parameter count for intval()" when I try this.

TY!

Note: This really should be in the wiki as an example somewhere.

Edit: Found it at the bottom here: https://github.com/CMB2/CMB2/wiki/Tips-&-Tricks and https://cmb2.io/docs/tips-&-tricks but couldn't find it search either of those docs directly...

I'm having the same, Wrong parameter count for intval()

I ended using this verification to see if is a numeric value and return an int:

function sanitize_int( $value, $field_args, $field ) {
	// Don't keep anything that's not numeric
	if ( ! is_numeric( $value ) ) {
		$sanitized_value = '';
	} else {
		// Ok, let's clean it up.
		$sanitized_value = absint( $value );
	}
	return $sanitized_value;
}

Hi,
I am unable to add default value using this method.
CMB2 version: 2.3.0

When I input any default param as 'default' => 55 then escape_cb function converts it to 0. As CMB2 returns escaped value in CMB2_Field::escaped_value(); function and do not consider default value before running escape_cb.

Unable to understand if this is something intentional or a bug in CMB2. A workaround is to use custom escape_cb and handle the scenario.

Thanks.

working beautifully!!!
