Boone Gorges 94791cd8f2 Respect 'default_option_' filters during early sanity checks in `add_option()` and `update_option()`.
`add_option()` and `update_option()` both call `get_option()` to compare the
value passed to the function with any existing value for the given option name.
When a `'default_option_'` filter is in place to change the default value of
an option, `add_option()` and `update_option()` ought to check against the
filtered value, rather than a hardcoded `false`, in order to determine whether
a prior value exists.

Boone Gorges 086e03e8e2 Improved handling of expectedDeprecated and expectedIncorrectUsage annotations in unit tests.
* Do the `expectedDeprecated()` check in `assertPostConditions()` instead of `tearDown()`. Previously, `fail`ing inside of `tearDown()` was causing the rest of the teardown process to be aborted, resulting in inter-test leakage.
* Collect all `expectedDeprecated` and `expectedIncorrectUsage` annotations in an entire method and display them all when `fail`ing, instead of showing only the first one.

2015-02-17 16:11:09 +00:00
Boone Gorges 8bf5fce78f Improve 'orderby' syntax for `WP_Comment_Query`.
Since [29027], `WP_Query` has supported an array of values for the `$orderby`
parameter, with field names as array keys and ASC/DESC as the array values.
This changeset introduces the same syntax to `WP_Comment_Query`.

We leverage the new support for multiple ORDER BY clauses to fix a bug that
causes comments to be queried in an indeterminate order when sorting by the
default `comment_date_gmt` and comments share the same value for
`comment_date_gmt`. By always including a `comment_ID` subclause at the end of
the ORDER BY statement, we ensure that comments always have a unique fallback
for sorting.

This changeset also includes improvements paralleling those introduced to
`WP_Query` in [31312] and [31340], which allow `$orderby` to accept array keys
from specific `$meta_query` clauses. This change lets devs sort by multiple
clauses of an associated meta query. See #31045.

Fixes #30478. See #31265.

Boone Gorges 4138275df9 More careful type conversion in `WP_Query` `is_*()` methods.
`is_array( 1, '1-foo' )` returns true, which means that `is_page( 1 )`
was returning true when on a page with the slug '1-foo'. We avoid this odd
behavior by casting the queried object ID to a string before testing against
the value passed to the conditional function.

This also helps to avoid a problem where an arbitrary value for `$page` would
cause `is_page( $page )` to return true if the query had been manipulated by
a plugin to show that the current page's ID is 0.

2015-02-11 22:44:20 +00:00
Boone Gorges ed639b408a Split shared taxonomy terms on term update.
When updating an existing taxonomy term that shares its `term_id` with
another term, we generate a new row in `wp_terms` and associate the updated
term_taxonomy_id with the new term. This separates the terms, such that
updating the name of one term does not change the name of any others.

In cases where a plugin or theme stores term IDs in the database, term splitting
can cause backward compatibility issues. The current changeset introduces
two utilities to aid developers with the transition. The `'split_shared_term'`
action fires when the split takes place, and should be used to catch changes in
term_id. In cases where `'split_shared_term'` cannot be used, the
`wp_get_split_term()` function gives developers access to data about terms
that have previously been split. Documentation for these functions, with
examples, can be found in the Plugin Developer Handbook. WordPress itself
stores term IDs in this way in two places; `_wp_check_split_default_terms()`
and `_wp_check_split_terms_in_menus()` are hooked to `'split_shared_term'` to
perform the necessary cleanup.

See [30241] for a previous attempt at the split. It was reverted in [30585]
for 4.1.0.

Boone Gorges bdda122e7f In `WP_Query::get_queried_object()`, avoid PHP notices when `is_tax` is paired with an empty `tax_query`.
It's possible to have an empty `tax_query` and `is_tax=true` when the initial
query contains a taxonomy var (and is processed as such during
`WP_Query::parse_query()`) but the taxonomy var is unset during a 'parse_query'
callback. While this kind of behavior is not necessarily something we need to
support, we should continue to avoid PHP notices in such cases, as we did prior
to WP 4.1.

Boone Gorges fb4048fcdd Parse non-hierarchical tag input into term IDs before sending to `wp_insert_post()`.
When editing a post, non-hierarchical taxonomy terms are sent as the
comma-separated list entered into the tax_input metabox. Passing these
values directly to `wp_update_post()` meant that they were interpreted as
term slugs rather than term names, causing mismatches when a typed string
matched the slug of one term and the name of a different term. We fix the
problem by preprocessing tax_input data sent from post.php, converting it to
unambiguous term_ids before saving.

Boone Gorges 41db99c31a Use field-specific sanitization in `WP_Tax_Query::transform_query()`.
When terms are entered into the database, term fields are sanitized with
`sanitize_term_field()`. To ensure that the `SELECT ... WHERE` queries in
`WP_Tax_Query::transform_query()` are not broken by overzealous sanitization,
`sanitize_term_field()` should be used in that case as well. This fixes a bug
where a tax_query using 'field=name' would fail if the 'terms' parameter
contained characters (like spaces) that were improperly removed by
`sanitize_title_for_query()`.

Boone Gorges 2e848072eb Don't use term IDs for array indexes when caching object terms.
Uncached results pulled from `wp_get_object_terms()` are zero-indexed (ie 0,
1, 2...). As a result, `get_the_terms()` was returning a strictly different
array when pulling from the cache and when the cache was empty.

Props joshlevinson.

Boone Gorges a57a612c95 Improve organiation of tax_query and meta_query unit tests.
`meta_query` tests have been moved to `tests/phpunit/tests/query/metaQuery.php` and `tax_query` tests to `tests/phpunit/tests/query/taxQuery.php`. This is an improvement because (a) it better corresponds to the way that other `WP_Query` parameter tests are organized, (b) splitting meta and tax tests into separate classes simplifies the required `@group` annotations, and (c) the tests have nothing to do with posts per se, and so do not belong in the `post` subdirectory.

The tests previously found at `tests/phpunit/tests/query/taxQuery.php` have been moved to `isTerm.php` in the same directory. These tests are related to the `is_*` functions that have to do with taxonomy terms, like `is_category()`.

See #26999.

Boone Gorges 9d3a6394fb Ensure that 'hierarchical' is respected in `get_terms()` when multiple taxonomies are passed.
Previously, attempts to descend the family tree of each term were done using
the first taxonomy in the `$taxonomies` array, with the result that terms not
belonging to that taxonomy were not found and their children not properly
parsed. We fix this bug by fetching each term's taxonomy with the SQL query,
and then using that taxonomy to get the correct children for each term.

Fixes #31118.
