Hi,

I'm trying to call a field from the settings page but it's just breaking my theme.
```
<?php $settings = get_option( 'my_options' );
 
$field_id = 'facebook-url';
if ( isset( $settings[$field_id] ) )
{
    return $settings[$field_id];
} 

?>
```

Hi, where do you put the code above into your theme? Maybe you should not return the result as you will use it in another way (display it or use as a variable). Using return in a PHP file will stop execution of the following code.

Hi, it's in the header.

I'm just using the code on this page; https://metabox.io/docs/mb-settings-page/

I have fixed it now using the following code;
```
<?php $field_id = 'twitter-url';
 if ( isset( $settings[$field_id] ) ) {
 echo '<li><a href=" ' . $settings[$field_id] . '"><i class="fa fa-twitter"></i></a></li>'; } ?>
```
How do I echo nothing if the field is empty?

Glad to see you figured it out. To echo nothing if the field is empty, you just need to change the code a little bit:
```
<?php
$field_id = 'twitter-url';
if ( !empty( $settings[$field_id] ) ) {
    echo '<li><a href=" ' . $settings[$field_id] . '"><i class="fa fa-twitter"></i></a></li>';
}
?>
```
