wordpress – filling out the contact form 7 from the database (lable | value)

I use the following to populate selected tag data:
in functions.php:

Function license_years () {
$ data = Array ("less than 1 year", "1 year", "2 years", "3 years", "4 years", "5 years", "6+ years"));
return $ data;
}

add_filter (& # 39; wpcf7_form_tag_data_option & # 39;) function ($ n, $ options, $ args) {
if (in_array (& # 39; wpcf7.data.licence & # 39 ;, $ options)) {
return license_years ();
}
return null;
}, 10, 3);

and then in the form I use this tag:

[select* licence data:wpcf7.data.licence]

This works fine, but I have to have the choice other value than the label I search and found nothing, help?
