Display field groups in separate lists

I have three field groups, named General Specifications, Standard Features, and Optional Extras.

In my code, I want to specify one field group at a time and output its field labels and values using the code below.

I don’t know how to select one field group at a time in my code – that’s where I’m getting stuck :/ I’d appreciate your guidance here, everyone!

Also – I’m a PHP beginner – trying to make things work 🙂

                <?php

                $fields = get_field_objects();

                if( $fields )

                {

                foreach( $fields as $field_name => $field )

                {

                echo '<li>';

                echo $field['label'] . ": ";

                echo $field['value'];

                echo '</li>';

                }

                }

                ?>

You could do this by looping through the fields 3 times and checking the parent. The value of $field['parent'] will be the group key for the group the field is in. So for example if your group key for the first group is group_5664a3d9a775b

foreach ($fields as $field_name => $field) {
  if ($field['parent'] != 'group_5664a3d9a775b') {
    // not in first group
    continue;
  }
  // display field
}
// to 2 more times for each of the other groups

Hey John,

Thanks for helping out here! I’ve taken your code and tried to get it working. On my side the code is not running – the resulting html just leaves me with the opening and closing

tags I’m using.

What am I doing wrong?

            <ul>
            <?php

            $fields = get_field_objects();
            if( $fields ) {

            foreach ($fields as $field_name => $field) {
              if ($field['parent'] != 'group_5937f81f79c5b') {
                // not in first group
                continue;
              }
                  echo '<li>';
                  echo $field['label'] . ": ";
                  echo $field['value'];
                  echo '</li>';
              }
              }
            ?>
            </ul>

what version of ACF are you using?

I was on 5.5.10, but just updated to 5.5.14. I get the same result.

The only think I can think by looking at your code is that none of your fields are in that group. Try displaying the list of fields to see what’s going on.

$fields = get_field_objects();
echo '<pre>'; print_r($fields); echo '</pre>';

John, thanks so much for helping out.

I’ve run the code you suggested, and you can see the results here (under the heading Optional Extras – the other two columns are coded line by line – not ideal): https://bushlapa.storiesandscience.co.za/caravans/goggas/rooimier/

Just to take a step back – what I’d like to achieve is the following:
– Display the field names and values from one field group at a time.
– Exclude any fields that do not have a value.

Here is a snippet of the printed result:

Array
(
    [dry_weight] => Array
        (
            [ID] => 439
            [key] => field_5937f37f96261
            [label] => Dry weight
            [name] => dry_weight
            [prefix] => acf
            [type] => text
            [value] => 620
            [menu_order] => 0
            [instructions] => 
            [required] => 1
            [id] => 
            [class] => 
            [conditional_logic] => 0
            [parent] => 303
            [wrapper] => Array
                (
                    [width] => 33
                    [class] => 
                    [id] => 
                )

            [_name] => dry_weight
            [_prepare] => 0
            [_valid] => 1
            [default_value] => 
            [placeholder] => 
            [prepend] => 
            [append] => kg
            [maxlength] => 
        )

    [total_length] => Array
        (
            [ID] => 440
            [key] => field_5937f3b496262
            [label] => Total length
            [name] => total_length
            [prefix] => acf
            [type] => text
            [value] => 3360
            [menu_order] => 1
            [instructions] => 
            [required] => 0
            [id] => 
            [class] => 
            [conditional_logic] => 0
            [parent] => 303
            [wrapper] => Array
                (
                    [width] => 33
                    [class] => 
                    [id] => 
                )

            [_name] => total_length
            [_prepare] => 0
            [_valid] => 1
            [default_value] => 
            [placeholder] => 
            [prepend] => 
            [append] => mm
            [maxlength] => 
        )

That’s interesting, when I output something similar the parent for me is the group key. In your case the parent is the post ID of the field group. I don’t know what the difference is, but whatever is in the parent is what you’ll need to look for.

Thanks again – I’ve implemented the code successfully, and also added an additional line of code so that empty fields do not display. Here’s the final code.

                  <ul>
                  <?php

                  $fields = get_field_objects();
                  if( $fields ) {

                  foreach ($fields as $field_name => $field) {
                    if ($field['parent'] == '303') {
                      if ($field['value'] == '') {
                      continue;
                    }
                        echo '<li><b>';
                        echo $field['label'] . ": </b>";
                        echo $field['value'];
                        echo '</li>';
                    }
                    }
                  }
                  ?>
                  </ul>
