PHP code in help text

This is way old, but you can make a custom module with hook_form_alter()

For example:

<?php
/**
 * Implementation of hook_form_alter().
 */
function MYMODULE_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'FORM_ID_OF_FORM_TO_ALTER') {
    $form['YOUR_FIELD_ID']['#description'] = t('Your help text goes here. You can do whatever you want to generate this text, including adding a <a href="@url">hyperlink</a>.', array('@url' => 'path/to/link/to'));
  }
}
?>

I've got to believe that a module could be made which brings PHP to all of the help/description fields. Anyone want to work on it? I am switching this to Drupal 7 core because this part of Drupal that has the fields and help text is a part of core AFAIK.

I doubt the proposition in #3 will ever be a part of drupal core.
A contrib module would be able to implement this though.

@rooby agreed. Is there a project name for desired contributed modules that have yet to be created that I could set this too?

Not that I know of.

There is an issue queue for new projects (by new maintainers) at https://www.drupal.org/project/issues/projectapplications but for that you have to post the already working module, it's not a wishlist.

Notice that this issue has been posted in issue queue for a sandbox project without code. It's not an issue queue to ask support for, or post bugs in, Drupal core or third-party modules.

Despite the project name, this sandbox project is not linked to Drupal core in any way, and it may be removed at any time.
