Draft. These are the two pre-existing bugs noticed while auditing field lists for wp-cli/wp-cli#5286, now with tests. Independent of #636 and #6392 — branched off main and reviewable on its own.

Same failure as #5286 reached from the other side: there the parameter name is wrong and the value is dropped, here the name is right and the value is dropped anyway. Both report success.

What's broken

Command Parameter Behaviour
user create --user_nicename documented, accepted, ignored
user create --rich_editing documented, accepted, ignored
post create --post_modified, --post_modified_gmt documented, accepted, ignored
post update --post_modified, --post_modified_gmt documented, accepted, ignored

User_Command::create() builds an explicit stdClass for wp_insert_user() and never sets either property. wp_insert_post() derives post_modified/post_modified_gmt itself and never reads them from $postarr — on update they are unconditionally current_time( 'mysql' ).

Note user create has no catch-all, so it is already strictly validated. It accepts these two parameters because they are documented, and then drops them.

Commits are test-first

b4355e0 adds the scenarios and fails. aeaa92b makes them pass. Reviewable in that order, and verified in that order with Behat by checking src/ out at each commit:

src/ at b4355e0 (tests only)   5 scenarios (2 passed, 3 failed)
src/ at aeaa92b (fix)          5 scenarios (5 passed)

The two that pass in both states are deliberate controls — nicename falling back to the login, and post_modified defaulting to now when not asked for. Without them a red run would not distinguish a real bug from a broken harness.

Full suites

Run on both database backends; the results are identical.

Suite MySQL SQLite
post.feature 22 scenarios, 22 passed 22 scenarios, 22 passed
post-create-duplicate.feature 5 scenarios, 5 passed 5 scenarios, 5 passed
user.feature 26 scenarios, 25 passed, 1 failed 26 scenarios, 25 passed, 1 failed

The one user.feature failure is pre-existing and unrelated. It is the multisite duplicate-email scenario, which expects Sorry, that email address is already used! while current core trunk returns This email address is already registered. Log in with this address or choose another one. Confirmed by re-running that scenario with src/ checked out at origin/main, where it fails identically. My diff does not touch it.

Tested against WordPress trunk (7.2-alpha), which is what this environment could obtain — worth noting since that is also the source of the message change above.

One regression this surfaced

Making post_modified live exposed a latent bug in post create --from-post. It copies the source post's fields and unsets post_date, post_date_gmt, guid and ID — but not post_modified. Harmless while core ignored it; with this change the duplicate would inherit the original's modification date instead of the current time. Fixed by unsetting it alongside post_date, with a scenario in post-create-duplicate.feature.

The design question

For post_modified the alternative is to remove the parameters from the docblocks rather than make them work. Smaller change, but it drops functionality the documentation has been advertising since it was added, and "set the modification date" is a reasonable thing to want from an admin tool. I went with making them work; inverting it is a small diff if you'd rather.

There is no such question for user create — those two are unambiguous.

Three documented parameters accept a value and drop it:

- `user create --user_nicename` and `--rich_editing`. User_Command::create()
  builds an explicit stdClass for wp_insert_user() and never sets either
  property, so both are read off $assoc_args nowhere.
- `post create` / `post update --post_modified` and `--post_modified_gmt`.
  wp_insert_post() computes both itself and never reads them from $postarr;
  on update they are unconditionally current_time( 'mysql' ).

All three report success. These are the same silent no-op as
wp-cli/wp-cli#5286, reached from the other side:
there the parameter name is wrong, here the name is right and the value is
discarded anyway.

These scenarios fail on main. The fix follows in the next commit.

Makes the tests from the previous commit pass.

user create: set user_nicename and rich_editing on the object handed to
wp_insert_user(). Both use the same `false` default as the neighbouring
properties, which core reads as "not supplied" - user_nicename then falls back
to the login and rich_editing to 'true'.

post create / post update: wp_insert_post() derives post_modified and
post_modified_gmt itself and never reads them back from $postarr, so apply the
requested value through the wp_insert_post_data filter, registered around the
insert and removed straight after. When only one of the pair is given the other
is derived from it, so the two never disagree.

That last change makes a previously harmless bug visible: `post create
--from-post` copies the source post's fields, and post_modified was not among
the ones it unset. Core ignored it before, so the duplicate got the current
time; now it would inherit the original's. Unset it alongside post_date, and
cover it with a scenario.

The alternative to all of this is to remove the parameters from the docblocks
instead. That is a smaller change but loses functionality the documentation has
been promising, so it seemed the wrong way round - happy to invert it.

# Conflicts:
#	features/post.feature
The pair was collected into an array with both keys optional, so nothing
told PHPStan that reaching the consistency check meant at least one of them
was present, and the values stayed mixed all the way into
get_gmt_from_date() and get_date_from_gmt().

Two scalars say the same thing in a way the analyser can follow, and the
array is built once both are known. is_scalar() guards the cast: a value
that is not scalar could not be a date anyway, and casting one to string is
what the strict rule is there to prevent.

No behaviour change - `! empty()` still decides whether each was given, and
the pair is still completed from whichever half arrived.

This comment was marked as resolved.

Three gaps, all raised on the pull request.

Only '--post_modified' was ever passed, so the branch that fills in the local
time from a GMT one was never run. It has a scenario now, and to make the
derivation visible rather than incidental the site is put in a timezone with
an offset: noon GMT is 07:00 in New York in January and 08:00 in June, and
both are asserted, on create and on update.

The scenario for the default modification date asserted only that the field
was not empty, which a stale value satisfies just as well as a fresh one.
It now sets a known date first and asserts the update does not leave it
behind.

Neither of the user scenarios ran on multisite, where the user is made by
wpmu_create_user() with a login, a password and an email, and everything
else is applied afterwards by wp_update_user(). That is a different path to
wp_insert_user() and it is covered now. Both new scenarios fail against
main, where the nicename comes back as the login instead.

The multisite login is 'robert' rather than 'bob' because multisite requires
four characters, which is a good illustration of why the branch was worth
testing separately.

Add local-to-GMT derivation coverage.

These scenarios assert only post_modified after local-only input. They do not verify the get_gmt_from_date() branch in src/Post_Command.php:294-295.

Set a non-UTC site timezone and assert the expected post_modified_gmt value after one local-only create or update. The GMT-only scenario does not cover this opposite derivation direction.

Tested this branch on stable WordPress 7.0.4 with PHP 8.3, since the PR could only be verified against trunk.

Works on stable:

  • Both user create parameters apply, with correct fallbacks when absent.
  • post_modified / post_modified_gmt derive each other correctly with a non-UTC timezone. I tested Asia/Kolkata in both directions.
  • --from-post gets a fresh modification date, and updates without these flags still set the current time.

One issue found: an invalid modification date is silently accepted.

Command tested: wp post create --post_title=x --post_status=publish --post_modified='banana'

Result: command reports success, but writes post_modified as 0000-00-00 00:00:00 and post_modified_gmt as 1970-01-01 00:00:00.

Same result with --post_modified_gmt='banana', and with both parameters on post update. All four variants report success and write bad or inconsistent date pairs.

The same input to --post_date gives Error: Invalid date. from core.

Cause: core validates post_date with wp_checkdate() before writing, but the filter injects the modification date after that validation. get_gmt_from_date() / get_date_from_gmt() then fall back to the epoch for unparseable input.

Suggestion: validate the date in add_post_modified_filter() and reject it the same way core rejects a bad post_date.

Note: tested on the SQLite integration, which coerces the invalid value to 0000-00-00. On MySQL with strict mode the insert may fail outright instead, which would be a different symptom of the same gap.
