For testing, you should install the
wp-cli, which allows us to have
a development version of a wordpress server running.
You need to have php installed to do this.
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
Move it to somewhere in your PATH and make it executable.
Next, create a database and user with access to it. The names should
be the following, or else you'll have to change the config file within
$ mysql -u root -p [enter password] mysql> CREATE DATABASE offset_test; mysql> CREATE USER 'offset'@'localhost' IDENTIFIED by '111'; mysql> GRANT ALL PRIVILEGES ON *.* TO 'offset'@'localhost' WITH GRANT OPTION;
Now change into the
wp directory and finish the install and start the server with:
$ wp core config --dbname=offset_test --dbuser=offset --dbpass=111 $ wp core install --admin_user=offset --admin_password=111 --url=localhost --title="Offset Test" --admin_email="firstname.lastname@example.org" $ wp server --port=5555
Set the permalink structure, activate the plugins, set the name of the admin, and set the application password:
wp option update permalink_structure '/%year%/%monthnum%/%postname%/' wp plugin activate --all wp user update 1 --display_name="Ira Rubel" --first_name="Ira" --last_name="Rubel" wp eval-file create_password.php
To test that it is working,
run the following command (requires the
jq utility, which you can
install on macs with
brew install jq):
curl http://localhost:5555/wp-json/ | jq
Which should print out a bunch of json.
Now clear the default and insert the needed test posts, as well as adding tags:
(TODO: Explain the WordPress plugins that are needed to make this work)
<wpPosts> - This tag accepts the following attributes:
num - should be an integer. the number of posts per page. Defaults to 20.
page - should be an integer. This is the current page (
1 is the first one) worth of posts.
limit - should be an integer, and this restricts the number of posts
that come back in the current page. Note that if you haven't set
page, changing this is equivalent to changing
num. If you have set
page, then the first
page full pages (each of size
skipped, and then the first
limit posts are returned. Defaults to
offset - should be an integer, and this affects how many posts are
skipped in the current page. If you don't set the
page, then this is
just the number of posts that are skipped before the first
posts are returned, but if you have set
page, the first
pages of posts (each of size
num) will be skipped, then an
offset posts will be skipped, and finally,
will be returned.
<wpPostByPermalink> - This tag expects to have the url be
/YYYY/MM/SLUG, and finds
the post accordingly.
<wpNoPostDuplicates/> - This is a side-effect only tag, that causes, from this point
in the page forward, no duplicate posts to be returned from
<wpPosts/>. This can make
certain layouts easier to express, rather than figuring out exactly how to combine the
various numeric arguments to avoid duplication.
