Hi there,

I have some taxonomy_advanced fields displayed in a frontend submission form. One of them is a select_advanced field handling a hierarchical two level taxonomy. The others are checkbox_list type fields.

I'm trying to set selected/checked options on form load using the rwmb_field_meta filter with a callback function that returns a coma separated list of some of the term IDs for the taxonomy (e.g. a string like '10,20,30').

However, only the first ID in the list is set both on the select_advanced and the checkbox_list fields types. What would be the right way to do this?

I'm using Frontend Submission and Custom Table extensions. Data saving is working fine in all cases.

Thanks
Marco

Hi Marco,

You can use the setting std to set a default value of the select_advanced field type. For example:
```
[
    'name'          => 'Taxonomy',
    'id'            => 'taxonomy',
    'type'          => 'taxonomy_advanced',
    'taxonomy'      => 'category',
    'field_type'    => 'select_advanced',
    'multiple'      => true,
    'std'           => array(2,3,4), //default term IDs
],
```

Is it possible to set a function to return this array? I need to get user email (and other data) in order to set the default options array. How could it be done?

Hi Long,

Just to let you know I've got a solution using rwmb_field_meta and setting $meta = array().

Thank you,
Marco
