Select one option from several radio buttons.

Return value

The internal identifier for the selected field. This is a string that does not change if even you change to names or the order of the radio buttons.

Extended Return Values

Returns an array with useful information:

Example

// Field slug is "radiobuttonsExample"
// Returned value does not say anything about the order of the radio buttons.
// You have to print the values before knowing what value each radio button has.
// It's wierd. But it's done like that so you can change the order of the buttons
// and the names of the buttons without having to change your code.
$selected_value = simple_fields_value('radiobuttonsExample');
if ($selected_value == "radiobutton_num_3") {
    echo "You selected button two";
}

Output of above

You selected button two
