Register Form: Key-Value-Pair for Checkbox

Hi @ysnz

It’s a bit complicated but here’s the code snippet to achieve the Key-Pair values for checkbox:

function um_021821_checkbox_array(){
    return [
        'apple' => 'Apple',
        'banana' => 'Banana',
        'carrot' => 'Carrot'
    ];
    
}
add_filter("um_field_checkbox_item_title", function( $um_field_checkbox_item_title, $key, $v, $data ){
    
    if( $key == 'key-pair' ){
        $arr = um_021821_checkbox_array();
        $um_field_checkbox_item_title = $arr[ $v ];
    }

    return $um_field_checkbox_item_title;
 }, 10, 4);

 add_filter("um_edit_key-pair_field_value", function( $value, $key ){
    $arr = um_021821_checkbox_array();
    return $arr[ $value ];
 }, 10, 2);

add_filter("um_profile_field_filter_hook__key-pair",function( $value, $data ){

    $arr = explode(", ", $value );
    $arr_reference = um_021821_checkbox_array();
    $arr_new_format = [];
    foreach( $arr as $a ){
        $arr_new_format[ ] = $arr_reference[ $a ];
    }

    return implode(", ", $arr_new_format);

},10, 2);

key-pair is the name of the checkbox field so you will have to change it in the code snippet above to match your field’s meta key.

um_021821_checkbox_array is function where you add the key-pair. You also need to add the values to the checkbox options via Form Builder. Use the slugs( e.g. apple, banana etc. ) as option values.
