Change module's weight - by module or manualy

Question

I am looking for solution how to change particular module's weight in D7. I know that it is possible to do in config tables in database, but I don't know how. Another solution that I found in Drupal.org is to use hooks - but I need more detail explanation or some guidance where I could get some tutorials about that.

The thing that I need to do is to make some priorities of some particular modules higher for it to load faster than other modules as otherwise they will not work. One of the examples is video streaming using Lightbox2 popup watching that on Safari browser on OS X - it's not loading until you change the priority of Lightbox module.

Answer 1

If you have access to phpmyadmin, you can look through the system table and when you find your module, you can click the little pencil icon to edit the row in the table. You would edit the weight column.

Answer 2

Since it was explicitly asked, there is also a module, Modules weight, that performs this task as well.

We always need to modify modules execution order, and some could write a code that execute a query to modify the weight of a module in system table, some might go straight to his favorite SQL client and modfiy the record directly, This module provide admin interface for users/people has the access to modules page to reorder the module weights as they want

Answer 3

What I have seen in different modules is that they do it directly in the database with a db_query call. Something like:

db_query("UPDATE {system} SET weight = 12 WHERE name = 'admin_views'");

Answer 4

You can use drush for this job as well. Use the commands below, and adapt the values of modulename and moduleweight to your liking:

1. Look up the current weight of your module:

   modulename="rdf"
   drush php-eval "drush_print_r(db_select('system', 's')
     ->fields('s', array('weight'))
     ->condition('name', '$modulename', '=')
     ->execute()
     ->fetchField()
   );"
   

2. Set the new weight of your module:

   modulename="rdf"
   moduleweight="1"
   drush php-eval "db_update('system')
     ->fields(array('weight' => $moduleweight))
     ->condition('name', '$modulename', '=')
     ->execute();"
