After some thought, I think we should create the parameter in the Modules Options and not the Menus options. In that case, we may not limit it to mod_menu and make it a totally new feature.

What do you think?

@infograf768 This should work for the check part.

if (JLanguageMultilang::isAdminEnabled())
{
	$languages = JLanguageHelper::getInstalledLanguages(1, true);
	$langCodes = array();

	foreach ($languages as $language)
	{
		$langCodes[$language->metadata['tag']] = $language->name;
	}

	$db    = JFactory::getDbo();
	$query = $db->getQuery(true);

	$query->select($db->qn('m.language'))
		->from($db->qn('#__modules', 'm'))
		->where($db->qn('m.module') . ' = ' . $db->quote('mod_menu'))
		->where($db->qn('m.published') . ' = 1')
		->where($db->qn('m.client_id') . ' = 1')
		->group($db->qn('m.language'));

	$mLanguages = $db->setQuery($query)->loadColumn();

	// Check if we have a mod_menu module set to All languages or a mod_menu module for each admin language.
	if (!in_array('*', $mLanguages) && count($langMissing = array_diff(array_keys($langCodes), $mLanguages)))
	{
		$app         = JFactory::getApplication();
		$langMissing = array_intersect_key($langCodes, array_flip($langMissing));

		$app->enqueueMessage(JText::sprintf('JMENU_MULTILANG_WARNING_MISSING_MODULES', implode(', ', $langMissing)), 'warning');
	}
}

JMENU_MULTILANG_WARNING_MISSING_MODULES="The administrator menu module for <strong>%s</strong> does not exist. Create a custom administrator menu and module for each administrator language or publish a menu module set to All languages."

Thanks. Committed after just changing name to nativeName.
This gives:

@mbabker @Bakual

Shall we set the parameter in the Modules Options instead of Menus Options?
In that case, shall we implement language filtering for all admin modules instead of only mod_menu?

Language filtering for admin modules would be good. This has come up before as a feature request

Just wondering if we even need an option. Would I r not be enough to check if the admin menu exists for the selected admin language

I'd say it would be the next logical step to be able to deliver different
language versions of any module on the administrator interface if we can
get the menu modules working, so if both can be accomplished at the same
time it would be great!

I will modify the PR to get the multilingual option for all modules.
Tomorrow or after tomorrow. Target 3.8 anyway . 😄

Ok, folks. We should get there.
To implement filtering one has now to set the option in the Modules Options instead of menus
I have preferred to keep the Option to let users chose.

When the site has only got one admin language, no filter or language field will be displayed.
Batch language for admin modules will now be done depending on admin languages and not content languages.

Please test with one language (en-GB) and 2 or more. Filter enabled and disabled.
Test with mod_menus as explained above and also with other admin modules (custom modules or feed modules are great to test with)

When fully tested, and if no issue please set test as OK on issues.joomla.org.
Michael left us until Friday to get this RTC and merged into 3.8.0

@izharaazmi
@RCheesley Please use patch tester.

I still dont see the need for the option - to me its enough to check if a menu module exists in the admin language being used. We have too many options. Would you ever have multiple menu modules in multiple languages if you didnt want this option?

I would advise any one commenting to first test the PR. It will be more useful.

Specially as we have a PR in 4.0 taking off the language field/columns, etc, when language filter is disabled, it is rather weird to read that a simple Option allowing or not filtering by admin language in the Modules Option could be a problem for backend modules.

@infograf768 Please resolve the conflicts and I'll test this.

Normally, conflicts are solved and both files have been modified by adding \ when necessary.
BUT we have an error when editing modules here:

Catchable fatal error: Argument 1 passed to Joomla\CMS\Form\Field\ChromeStyleField::setup() must be an instance of Joomla\CMS\Form\Field\SimpleXMLElement, instance of SimpleXMLElement given, called in /Applications/MAMP/htdocs/testnew/infograf768/libraries/src/Joomla/CMS/Form/Form.php on line 1925 and defined in /Applications/MAMP/htdocs/testnew/infograf768/libraries/src/Joomla/CMS/Form/Field/ChromestyleField.php on line 98

which means the PR cant be tested until this is solved as my PR does not touch these files.

@mbabker

That is caused by namespacing classes without updating namespace references
used inside those files. Many files are affected by this. I am trying to
find them but it isn't easy at this stage.

that error has now been fixed in staging. i guess you can now test

@izharaazmi
I have no idea why, but a custom admin menu tagged to a language (not All) is not any more sending a warning if some compulsory menu items are missing. That was working before the 3.8.0 merge.

To be more precise, it justs show the warning when the mod_menu loaded is tagged to the same language as the UI.
If I am in en-GB, it will not show the warning for an admin menu module tagged to fr-FR.

This should not be true as I wrote the code, not sure if it was modified
later. Will check it in an hour or so.

@izharaazmi
I think I found the issue.
As we only load mod_menus tagged to ALL and the language in use,

$menu = new JAdminCssMenu;
$menu->load($params, $enabled);

the check is only done on loaded custom menus.

@izharaazmi
Any way to still get the check to be done on all mod_menus, even if not loaded?

Currently I am working on a system check feature view in com_admin which would allow plugins as well as other extensions to inject their check methods. That would be helpful in this case as well. But seeing the feature freeze tomorrow, it looks like I could not make it into 3.8.0

Now at current scenario, we don't need the check for non loaded menu. That check offers the active user a recovery_mode option and that would be sufficient for the situation where the loaded menu does not have the required items.

Currently I am working on a system check feature view

@izharaazmi Happy to read that. Ping me if you nead any help.

@izharaazmi
In that case, and if your tests are fine, can you mark this PR tested OK on issues.joomla.org?

@wojsmol
Please also test so that we get this in 3.8.0

@infograf768 I will test tonight (Polish time).

Sure I'll test this evening :)

I have tested this item ✅ successfully on c9536f3

Test ok for me

@infograf768 I have two things in my mind:

1. If frontend language filtering is enabled by default unconditionally why would we want a setting for administrator modules?
2. If we really should have this option then it should be called JModuleHelper::isAdminMultilang() instead of JLanguageMultilang::isAdminEnabled() because the latter sound like If multilang is enabled in backend, which is not intended here.

@infograf768 After you put your opinion about the above I will submit my test result.

@izharaazmi
concerning 1. there is already a pr for 4.0 where all language fields/columns/ etc. would not be proposed/displayed if the language filter plugin is disabled, therefore also for frontend modules.

concerning 2. I just thought it would be simpler and more consistent to add the check in the same file as frontend. This as the JLanguageMulltilang class already exists. We must not forget that this new feature will also work for monolingual sites where multiple languages are installed (choice by backend user). Your idea would also work. Just a matter of choice I guess. I may have though that the new method may find a use (once modified) for other stuff than modules.

the new method may find a use (once modified) for other stuff than modules.

Correct. Therefore this check should not be bound to com_modules params anyway, I guess?

@infograf768 I'd rather try getting this into 3.8 first, and we can discuss these later 😄 👍

@infograf768 My tests are ok, just added few comments please reply to them.

@izharaazmi

the new method may find a use (once modified) for other stuff than modules.

Correct. Therefore this check should not be bound to com_modules params anyway, I guess?

"Should not be bound ONLY to..." .
This is why I wrote above "once modified":

I may have though that the new method may find a use (once modified) for other stuff than modules.

The code for example for specific enabled plugins or user groups or whatever would be "added" to the one checking the admin modules params.

if "something" || "somethingelse" || "anothercondition" || "the modules params"
{
     $enabled = true;
}

if judged necessary, we may then add a new method in JModuleHelper and use it in JLanguageMultilang::isAdminEnabled() to keep things in a handy place.

We could do that right now, but we are in a hurry to get this in 3.8.0
😃

If this is satisfying, please add test in issues.joomla.org

I mean my comments at:

1. https://github.com/joomla/joomla-cms/pull/17215/files#diff-8ed8ce099f4441c02ccafb2574fe4e45R15
2. https://github.com/joomla/joomla-cms/pull/17215/files#diff-8ed8ce099f4441c02ccafb2574fe4e45R35

did not get these, weird.
Looking

Done, if I understood correctly

I have tested this item ✅ successfully on 31abf2d

Filters working for backend modules and new configuration parameter enables/disables filtering feature correctly.

I guess this counts as 2 tests as the changes were not affecting code. Right?

Is this RTC?

RTC after two successful tests.

@infograf768 I see RTC but if enything is neadet plese ping me.

@izharaazmi @mbabker

After a good night sleep, I think @izharaazmi was right. 😃
If an admin language filtering may be necessary in the future for other stuff than the modules, we better move the conditional method into JModuleHelper.

This would mean adding a similar method for each element concerned in back-end with the possibility to enable or not such admin lang filtering by checking a specific parameter.

Admins will then be able to choose, element by element, what they want to be filtered or not.

Now that this PR is merged, it is quite easy to make a new PR changing that aspect of it.
It is not as urgent as the new feature.
Would you like me to prepare that now?

I have a patch from last evening ready! :)

LOL
Let's wait for @mbabker feedback

You guys will use this more often than me, so whatever makes sense to you roll with it.

@izharaazmi
you do or i do?

@infograf768 I already did the patch which was aimed against your branch
last evening. I can do that against staging now.

See #17314
