how can I get the choices of a select field? For example, I have a list (id: mylist) and 3 choices (red, blue, yellow) and I want to list them on the front end.
I have the custom post type "listing", related to this custom post type I try to use this code to show all available choices of my select custom field "city":
You should add the code to the template of the listing post to get the current post ID. If not you need to pass the post ID to the function. And the return value is an array so you need to use the function var_dump() or print_r() to print out the value.
For example:
$field = rwmb_get_field_settings( 'city', '', 123 ); // 123 is the post ID
echo '<pre>';
print_r( $field );
echo '</pre>';
Use the function print_r() to know the data structure of the field settings. You will need to have a basic knowledge of coding to echo the choice. For example:
$field = rwmb_get_field_settings( 'city', '', 123 ); // 123 is the post ID
$field_choices = $field['options'];
foreach ($field_choices as $value => $label) {
echo "Value: " . $value;
echo "<br />";
echo "Label: " . $label;
echo "<br />";
}
