Make "Add more values" button text themeable?

Hey,
Try this: http://drupal.org/project/stringoverrides

In the CCK handbook:

- Code snippet: How to change the label of the "Add more items" button.

Here is a patch that makes the button text themeable which would make the process much easier
seeing as you can't just form_alter it in the usual manner.

Where do you theme this text?

You can either do it in the manner suggested in #2, which is fairly complex just to theme some text on a button
OR
you apply the patch in #5 and then in your theme put this code in your template.php file

<?php

/**
 * Theme the label for the "Add more values" button
 */
function YOURTHEMENAME_content_multigroup_add_more_label($group_name) {
  return t('Add more values');
}

?>

Then you just change the 'Add more values' part of that code snippet to be whatever text you want on the button.

Thanks!

Any help you could be on http://drupal.org/node/156860 would be greatly appreciated. I really need that functionality and it looks like it's working for others.

Patch applied. I agree this makes more sense.

I want to change "Add more values" only for one multigroup field named "group_order_line". I added the following to my template.php:

function acquia_marina_content_multigroup_add_more_label($group_order_line) {
return t('Add more products');

The "Add more values" of other multigroup fields also changes.
How can I limit the change to one field or one content type?

I use Content Construction Kit (CCK) 6.x-3.0-alpha3

The $group_name parameter of the theme function is the name of the group currently being themed,
so to just do that particular group you could do:

<?php
/**
 * Theme the label for the "Add more values" button
 */
function acquia_marina_content_multigroup_add_more_label($group_name) {
  // For the group_order_line group.
  if ($group_name == 'group_order_line') {
    return t('Add more products');
  }
  // For all other groups.
  return t('Add more values');
}
?>

To do it for a particular content type you could do (or you could use the solution in #2):

<?php
/**
 * Theme the label for the "Add more values" button
 */
function acquia_marina_content_multigroup_add_more_label($group_name) {
  // For the page node type add page.
  if (arg(0) == 'node' && arg(1) == 'add' && arg(2) == 'page') {
    return t('Add more products');
  }
  // For the page node type edit page.
  else if (arg(0) == 'node' && is_numeric(arg(1)) && arg(2) == 'edit') {
    $node = node_load(arg(1));
    if (!empty($node) && $node->type == 'page') {
      return t('Add more products');
    }
  }
  // Otherwise.
  return t('Add more values');
}
?>

You can also add the group name check from the first example in the second example to just do a single group from particular content type.

Might be nice to pass the $node to the theme as well as the group name, as a second argument. If someone wants to make a patch for that we can make that change.

Yeah, I was thinking that when I started having to do node loads in the template.php example above.

Will do when I get some time.

@Agileware
Thank you! #11 works great.

Here is a patch to pass the node into the theme function for easier themeing.

Fwiw, this can be form_altered by targeting, for example, with a "field_presenters" user-reference field:

$form['field_presenters']['field_presenters_add_more']['#value'] = t('Add another presenter');

I'm not sure whether or not that satisfies the need provided by this patch.

After further thought, if we had a theme function to change every button's value/label, we'd have a ton of theme functions. hook_form_alter() is effectual here, and I think that eliminates the need for this patch.

@ezra-g:
Also note that this issue is regarding the add more button for a CCK 3 multigroup, not just a single field's add more button.
