Hi,

I am trying to populate a select field with a text field from a repeater but it is giving me a 500 error that is difficult to debug.

The repeater is part of the same custom post. Not too much documentation on how to go about this.

thanks,

Paul

add_filter('acf/load_field/name=no_complete_target', 'acf_load_complete_field_choices');

function acf_load_complete_field_choices($field){
    $post_id     = get_the_ID();

    if ( have_rows( 'group', $post_id ) ):

        while ( have_rows( 'group', $post_id ) ) : the_row();

            if ( have_rows( 'result', $post_id ) ):

                while ( have_rows( 'result', $post_id ) ) : the_row();

                    $title = get_sub_field( 'result_title', $post_id );
                    // once this works this will be 
                    //    $field['choices'] = $title;
                    echo $title . '';

                endwhile;
            endif;

        endwhile;

    endif;

    return $field;
}

Hi,

I figured out that this is not possible.

Repeater
– Repeater
-Text Field
– Repeater

Hi,

I figured out that this is not possible.

Repeater
– Repeater
– – Text Field
– Repeater
– – Select Field Loaded from Text Field Above

The error was Trying to get property of non-object

So I rethought the data and realized I dould get rid of one of the parent repeater went with this

– Repeater
– – Text Field (result_title)
– Repeater
– – Select Field Loaded from Text Field Above (yes_complete_target)

The code then is

add_filter('acf/load_field/name=yes_complete_target', 'acf_load_complete_field_choices');

function acf_load_complete_field_choices($field){

    global $post;

    $post_id = $post->ID;

    $field['choices'] = array();

    //Get the repeater field values
    $choices = get_field( 'dt_result', $post_id );

    $keys = array_keys($choices);
    for($i = 0; $i < count($choices); $i++) {

        foreach($choices[$keys[$i]] as $key => $value) {

            if($key == 'result_title'){
                $title = $value;

                //echo $value . "<br>";
                $field['choices'][$title] = $title;

            }
        }
    }

    return $field;

}
