Question

I’ve got multiple form_alters in my D7 website. One contrib and one custom. I need the custom module to overwrite the contrib module. But for some reason, the custom module is committing second…
How can I change the processing order of the hook_alters in Drupal?

Answer 1

You just need to pop into the system table in your database and change the status column for your module. If you want your hooks to run before another particular module’s then change status to a smaller number than the other module’s status in the table. If you want them to run after, change the status to a greater number.

You’ll need to clear Drupal’s cache once you’ve made the change in the table so it gets picked up.

See How to update a module’s weight for a fuller explanation.
