Radio buttons
One choice from a short list, with every option visible, such as the position of the logo.
In the editor
Besides the settings every field shares, radio buttons have:
| Setting | What it does |
|---|---|
| Field values | The choices. Every row has a value (what is stored) and a label (what you see on the options page). Move the rows up or down with the arrows to change their order. |
On the options page
As long as nothing is saved, the first choice is selected.
The value
Stores the value of the chosen row, not its label. A value that is not in the list becomes empty.
On your website
The shortcode and blocks show the stored value. When the value is no longer one of the choices, they show nothing.
$position = get_option( 'logo_position', 'left' );
echo '<header class="logo-' . esc_attr( $position ) . '">';
