Note that the multiple setting is always set to false for this field.

Sample code

array(
    'name'    => 'Radio',
    'id'      => 'radio',
    'type'    => 'radio',
    // Array of 'value' => 'Label' pairs for radio options.
    // Note: the 'value' is stored in meta field, not the 'Label'
    'options' => array(
        'value1' => 'Label1',
        'value2' => 'Label2',
    ),
    // Show choices in the same line?
    'inline' => false,
),

Data

This field simply saves a single selected value in the database.

If the field is cloneable, then the value is stored as a serialized array in a single row in the database.

Template usage

To get the field value, use this code:

$value = rwmb_meta( $field_id );
echo $value;

The rwmb_meta() function returns the value saved in the database (the value in the options array). If you want to display the label, use this code:

rwmb_the_value( $field_id );
