WordPress 4.0.1

Yessss!!!!

(upgraded yet?)

(sigh) ... 30+ wordpess instalations to upgrade ...

Possible solution: Wordpress Multisite?

Nooo ... !!!

painfull migration
user management problems
bugs no one seems to cate about
one big database
...

Wordpress Multisite is a problem not a solution!

Autoupdate?

Do you trust?

Technically, a random user makes the upgrade.

stupid rental car keys.. they give you TWO, but the keychain doesn't come apart, so, um, what's the point?

Note: Autoupdate is still better than no-update!

WP-CLI

Finally :)

Upgrades from 2 days to 2 hours
No more logging in
Technically no need for superadmin
Real chronjobs!

But ...

You need shell access ...

Installation

Easy: just copy-paste from http://wp-cli.org


curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

php wp-cli.phar --info

chmod +x wp-cli.phar
sudo mv wp-cli.phar /usr/local/bin/wp

Admin rights needed for the last step.

To be done once for one server.

So, how do I upgrade


cd /path/to/wordpress

wp core update
wp core update-db

Less than a minute (depends on download time).

Downloaded file is cached, so all other sites are upgraded even faster.

How about plugins and themes?


wp plugin update --all

wp theme update --all

Here the downloaded files are also cached.

Is that all?

No,it's just a beginning.

Everything is possible. Example: new wordpress installation:


wp core download
wp core config --dbname=wp --dbuser=mojuser --dbpass=supergeslo123 --locale=sl_SI
wp core install --url=example.com --title="Moj 382ti blog" --admin_user=janez --admin_password=supergeslo [email protected]

Wordpress is ready! You can start writing!

Install a new theme or plugin


wp plugin install wordfence
wp plugin activate wordfence
wp theme install suevafree
wp theme activate suevafree

# list of all installed plugins (works for themes too)

wp plugin list
+-----------+----------+-----------+---------+
| name      | status   | update    | version |
+-----------+----------+-----------+---------+
| akismet   | inactive | available | 3.0.2   |
| hello     | inactive | none      | 1.6     |
| wordfence | active   | none      | 5.3.3   |
+-----------+----------+-----------+---------+

Beware! New theme installation is so cool, this can happen:

User management


wp user create test [email protected] --role=editor --send-email

Success: Created user 2.
Password: LEAOY4OqouQ@

# user list

wp user list
+----+------------+--------------+-------------------+---------------------+---------------+
| ID | user_login | display_name | user_email        | user_registered     | roles         |
+----+------------+--------------+-------------------+---------------------+---------------+
| 1  | janez      | janez        | [email protected] | 2014-11-22 11:17:22 | administrator |
| 2  | test       | test         | [email protected]  | 2014-11-22 12:01:29 | editor        |
+----+------------+--------------+-------------------+---------------------+---------------+

Almost anything is possible

Very handy for operations that tend to time out.

Import/Export
Search/Replace, in database, that takes into account serialized arrays!
Thums regeneration, media files import!
Categories, posts, comments, navigation management ...
... and ... developper candy ...

WP console

A php console with Wordpress preloaded!


wp shell
wp> wp_title();
Moj 382ti blogNULL
wp> get_the_title(1);
string(12) "Hello world!"
wp> $post = get_post(1);
wp> setup_postdata($post);
