Adding fields to user group admin form

Question

I am trying to write a Joomla plugin to add fields to the user group admin form.

I have previously written plugins that have added a new tab to the user form. This is possible by having a plugin with the onContentPrepareForm method, and calling $form->load() or $form->loadFile() to inject the XML for the new tab of fields into the existing form.

As I say, this works well for the user form, but does absolutely nothing at all on the group form.

I have written a plugin, referenced the form name as com_users.group, and called $form->load() to inject my form XML. The XML is valid and no errors are reported, but the new form fields do no show up.

I guess that this is because the user form is already defined with multiple tabs, whereas the group form is much simpler and is not.

I've also tried adding the individual fields to the existing form (with without creating a new tab) by using $form->setField(), but this also isn't having any effect.

In either case, when I do a var_dump($form) after injecting my fields, I can see the new fields in the form's XML object structure, but they are not in the right place in the structure, which I guess is why they're not showing up.

Can anyone help point me in the right direction here? It's getting quite frustrating.

Thank you.

The group edit.php template file won't render any additional fields that might exist on the form, as it seems to be quite simple and somewhat static.

Likely you are going to need a template override, where you will iterate over the custom fields of your fieldset and render them.

Under the core fields, something like below could work:

<?php foreach ($this->form->getFieldset('YOUR_CUSTOM_FIELDSET') as $field) : ?>
    <div class="control-group">
        <div class="control-label">
            <?php echo $field->label; ?>
        </div>
        <div class="controls">
            <?php echo $field->input; ?>
        </div>
    </div>
<?php endforeach; ?>
