@liquidws– Welcome to the Piklist community!

When you create a group field you don’t have to assign the entire group to field (i.e. member_phone_group).

1) Assigning the group to a field.
If you assign the entire group to a field like you did, then that field is an array, and all the other fields are part of it:

Array
(
    [member_phone_areacode] => Array
        (
            [0] => 212
        )

    [member_phone_three] => Array
        (
            [0] => 555
        )

    [member_phone_four] => Array
        (
            [0] => 1212
        )

)

2) Not assigning the group to a field.
You don’t have to assign a group to a field. By removing 'field' => 'member_phone_group', all the other fields will save individually (not part of an array), and they can be accessed normally.

Does that make sense?

Your new code would be:

piklist('field', array(
    'type' => 'group'
    //,'field' => 'member_phone_group'
    ,'label' => 'Phone'
    ,'list' => false
    // ,'description' => 'A grouped field. Data is not searchable, since it is saved in an array.'
    ,'fields' => array(

      array(
        'type' => 'text'
        ,'field' => 'member_phone_areacode'
        ,'columns' => 1
        ,'attributes' => array( 'placeholder' => '956' )
      )
      ,array(
        'type' => 'text'
        ,'field' => 'member_phone_three'
        ,'columns' => 2
        ,'attributes' => array( 'placeholder' => '333' )
      )
      ,array(
        'type' => 'text'
        ,'field' => 'member_phone_four'
        ,'columns' => 3
        ,'attributes' => array( 'placeholder' => '4444' )
      )

    )
));

@liquidws– I just emailed you the latest beta 0.9.5u which allows for this. It extends the limit validation rule.

Add this to your field configuration:

    ,'validate' => array(
      array(
        'type' => 'limit'
        ,'options' => array(
          'min' => 3
          ,'max' => 3
          ,'count' => 'characters'
        )
      )
    )

We definitely appreciate the kind words, but we already Piklist is awesome. 😉

If you could let the world know by leaving a 5 star review on WordPress.org it would really help promote the project.

@liquidws– We really appreciate the review. Thanks so much!

As for Simple Directory Plugin, we pulled a function out of the beta, but it looks like some plugins are using it.

Add this to the bottom of class-piklist-admin.php, BEFORE the final closing bracket.

  public static function responsive_admin()
  {
    if (version_compare($GLOBALS['wp_version'], '3.8', '>=' ))
    {
      return true;
    }
    else
    {
      return false;
    }
  }

That should fix the Simple Directory Plugin.
