function hook_update_projects_alter

Alter the list of projects before fetching data and comparing versions.

Most modules will never need to implement this hook. It is for advanced interaction with the Update Manager module. The primary use-case for this hook is to add projects to the list; for example, to provide update status data on disabled modules, themes, and layouts. A contributed module might want to hide projects from the list; for example, if there is a site-specific module that doesn't have any official releases, that module could remove itself from this list to avoid "No available releases found" warnings on the available updates report. In rare cases, a module might want to alter the data associated with a project already in the list.

Parameters

$projects: Reference to an array of the projects installed on the system. This includes all the metadata documented in the comments below for each project (either module, theme, or layout) that is currently enabled. The array is initially populated inside update_get_projects() with the help of _update_process_info_list(), so look there for examples of how to populate the array with real values.

Code

  // Hide a site-specific module from the list.
  unset($projects['site_specific_module']);

  // Add a disabled module to the list.
  // The key for the array should be the machine-readable project "short name".

    // The date stamp when the project was released, if known. If the disabled
    // project was an officially packaged release from drupal.org, this will
    // be included in the .info file as the 'datestamp' field. This only
    // really matters for development snapshot releases that are regenerated,
    // so it can be left undefined or set to 0 in most cases.
    'datestamp' => 1243888185,
    // Any modules (or themes) included in this project. Keyed by machine-
    // readable "short name", value is the human-readable project name printed
    // in the UI.
