Echo when certainfield is not empty

Hi,
On my website I am using wp members plugin.
I want to only display some content when a custom field is not empty.
Field is called wpmem_rnr. It is hidden during registration and can be filled by an admin.
Using the shortcode [wpmem_field field=”wpmem_rnr”] will show the field to the loggedin user.
Now I want to echo a specific text, only when this field is filled.
I was using:
```
function show_coin () {
  if( get_field('wpmem_rnr') ) {
	  echo get_field('wpmem_rnr') . ' Ja het werkt' ;
  }
}
```
But this does not do the trick.

Any help will be appreciated.
Regards,
Arjan

There is in fact a get_field() function in WP, but that is not at all how it is used (it’s for post information, not users).

The function you’re looking for would be WP’s get_user_meta() which retrieves user meta (all WP-Members custom fields are going to be user meta in WP’s db schema).

The get_user_meta() function needs the field meta key (‘wpmem_rnr’ in your case), but it also needs the user ID. Depending on how/where you’re using this, you’ll need to consider if the user is the currently logged in user (in which case you can use WP’s get_current_user_id()), or if you need to pick up the user ID from somewhere else. I’m going to assume you’re displaying to the currently logged in user:
```
function show_coin() {
    $user_id = get_current_user_id();
    $field = get_user_meta( $user_id, 'wpmem_rnr', true );
    if ( $field && '' != $field ) {
        echo $field . ' Ja het werkt';
    }
}
```
Alternative to using get_user_meta(), WP-Members has an API function wpmem_get_user_meta() which always passes “true” for get_user_meta()‘s $single parameter (since any field data WP stores is going to be $single = true. This allows you to shorthand the usage by one less argument in the function:
```
function show_coin() {
    $user_id = get_current_user_id();
    $field = wpmem_get_user_meta( $user_id, 'wpmem_rnr' );
    if ( $field && '' != $field ) {
        echo $field . ' Ja het werkt';
    }
}
```
