#12671 assigned enhancement

Installer page doesn't check if MySQL tables were created successfully

When running the web-based setup script - My Mysql user didn't have create permissions so no tables were created but the message (underneath all the MySQL errors) said setup was successful.

I think it would be worth doing a check for no MySQL errors before proclaiming the installation a success.

I think it would be worth doing a check for no MySQL errors before proclaiming the installation a success.

Good idea. I think it should run with $wpdb->show_errors on.

This one came in a little late for 3.0. Patches welcome :)

It might also be nice if possible to have a generic "capability" check for the mysql permissions that the db user has.

So that the core code / plugin can check to see if the db user has be granted x or y before it tries to do something.

Ran into this bug today. Very surprised, and disappointed, to see that this thread was opened over 4 years ago.

For WP-CLI, I've decided to assume any database errors during wp_install() is partial or total installation failure.

dbDelta() returns pretty helpful data for determining whether an installation was successful:

array (
  'wp_users' => 'Created table wp_users',
  'wp_usermeta' => 'Created table wp_usermeta',
  'wp_terms' => 'Created table wp_terms',
  'wp_term_taxonomy' => 'Created table wp_term_taxonomy',
  'wp_term_relationships' => 'Created table wp_term_relationships',
  'wp_commentmeta' => 'Created table wp_commentmeta',
  'wp_comments' => 'Created table wp_comments',
  'wp_links' => 'Created table wp_links',
  'wp_options' => 'Created table wp_options',
  'wp_postmeta' => 'Created table wp_postmeta',
  'wp_posts' => 'Created table wp_posts',

It would be nice if we could change the return signature of make_db_current_silent() to return this data, or just call dbDelta() directly in wp_install().

Because MySQL permissions can be restricted for table creation or SELECT, UPDATE, or DELETE statements, I think it would be difficult to write an interpreter for all potential errors.

Couple of options to improve things:

  1. Inspect the response value of dbDelta(), and warn the user if any tables weren't created as expected.
  2. Inspect $wpdb->last_error after make_db_current_silent(), populate_options(), and populate_roles() are called. It should be empty. If it's not, we can let the user know there were database errors on installation.

I'm not sure how to communicate "there were database errors on installation" to the end user, given they may be incapable of resolving them on their own. However, anything we do is better than the success message we currently show.
