I've been trying to extend tx_news with a m:m relation with not much luck so far. Anything I can find online is just for a regular relation, where the ID is saved directly into the same table, not an extra _mm column.
The backend looks fine so far, the way I want it with a selectMultipleSideBySide renderType. It also saves the relations to the database.
Extending the News TCA with this, works fine:
$extendArtistId = array(
'artist_id' => array (
'exclude' => 0,
'l10n_mode' => 'exclude',
'label' => 'Künstler',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'enableMultiSelectFilterTextfield' => TRUE,
'foreign_table' => 'tx_bfartistmanagement_domain_model_kuenstler',
'foreign_table_where' => 'AND tx_bfartistmanagement_domain_model_kuenstler.sys_language_uid = 0 AND tx_bfartistmanagement_domain_model_kuenstler.pid = 63 ORDER BY tx_bfartistmanagement_domain_model_kuenstler.name ASC',
'MM' => 'tx_news_domain_model_news_artist_id_mm',
'minitems' => 0,
'maxitems' => 99
),
),
);
And the entries are saved the way I expected:
The problem I'm having now is getting these relations from a different extension. News has something called "Hooks", but I'm not sure I want/need that for my case.
The query inside my other extension currently looks like this, newsRepository being injected:
$news = $this->newsRepository->findByArtistId(intval($userID));
I struggle with the next step(s). The function findByArtistId was working before as I was saving the artistId directly inside the news table, but that only works with a direct relation, not an M:M one.
How can I get the News that are associated with that artist, with an m:m relation?

'passwordtype' => [
'exclude' => false,
'label' => '###label####',
'config' => [
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'passwordtypes',
'foreign_sortby' => 'name',
],
],
That part of the tca works like a charm. The passwordtypes are getting sorted by name when I open the record of a password in the backend.
But I want the sorting of the passwordrecords also happening by the passwordtypes. So I tried 'sortby' => 'passwordtype' under 'ctrl' but that only sorts it by the uid, not by the name of the passwordtypes.
I also tried 'sortby' => 'passwordtype.name' but that creates an error. Is it possible to sort it by the name of passwordtypes instead of the uid? It clearly has the name of the passwordtypes already in the passwordlist because when I change the 'label' under 'ctrl' to 'passwordtype' than I can see the correct names and not uids.
I'm open for every idea even if I have to change my database-structure.
Let's dive into the core...
The record lists are generated via \TYPO3\CMS\Recordlist\Controller\RecordListController::main(). Fot getting the list itself, the method calls
\TYPO3\CMS\Recordlist\RecordList\DatabaseRecordList::generateList().
generateList() does select data only from the actual table itself. No relations are resolved here. Then it becomes clearer why sorting by fields of a relation is not possible: they are not part of the selected data.
But... The labels of foreign records are shown.
Yes, that's done while rendering a concrete row of the list. At that
moment, no sorting can be applied anymore.
But... It works for sorting by UIDs.
Yes and no. You have a 1:n relation, so the UID of the foreign record
is saved as foreign_key in your (passwordrecords) table. The
'sortby' => 'passwordtype' is not applied to the table
passwordtype but to the column passwordrecords.passwordtype containing these UIDs.
Conclusion:
Out of the box, there seems not to be an option for sorting by a foreign table field.
Maybe, you can hook into the recordlist by \TYPO3\CMS\Backend\RecordList\RecordListGetTableHookInterface::getDBlistQuery() (called in \TYPO3\CMS\Recordlist\RecordList\DatabaseRecordList::getTable) and modify the query parts to meet your needs.
Simply put the order in are foreign_table_where:
'passwordtype' => [
'exclude' => false,
'label' => '###label####',
'config' => [
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'passwordtypes',
'foreign_table_where' => 'AND 1=1 ORDER BY name',
],
],
I'm trying to add a column to the relation table (MM table) in Typo3. Let's say I have my tables user, wanted_car and wanted_car_mm which is my relation table. So in wanted_car_mm I'll know what user want which car, but I want to add the column need_faster in wanted_car_mm, which is a boolean, that tells me who should have it faster. A lot of users could need it faster, there's no order.
How do I add this column, map the value and correctly retrieve this information when I get all my users?
I currently have this in my TCA config for user:
'wanted_cars' => array(
'exclude' => 1,
'label' => 'LLL:EXT:caa_my_plugin/Resources/Private/Language/locallang_db.xlf:my_title',
'l10n_mode' => 'exclude',
'config' => array(
'type' => 'select',
'foreign_table' => 'wanted_car',
'MM' => 'wanted_car_mm',
'MM_insert_fields' => array('need_faster' => '???'),
'MM_table_where' => ' AND wanted_car_mm.need_faster = ???',
'maxitems' => 9999,
'multiple' => 0,
'renderType' => 'selectCheckBox',
),
),
I feel like this is how I should add the column and retrieve it correctly, but I have no clue how to map the correct value.. that I should also put in my where clause.. I don't know how this can be possible going like this, but I can't find any other way of doing it.
The value must be specified when creating a user.
You need an intermediate table for that. The full docs for that can be found on https://docs.typo3.org/m/typo3/reference-tca/master/en-us/ColumnsConfig/Type/Inline.html
a screenshot and old example which still should work can also be found on https://wiki.typo3.org/Inline_Relational_Record_Editing_Attributes
TLDR:
I've got two models with MM-Relations with different StoragePids defined via Constants in my template.
I don't know how to filter results while querying my data regarding my configured storagePids for my related Model.
Long version:
In my multisite-TYPO3 installation I've got two models "Person" and "PersonalInformation". These models have a MM-Relation defined via TCA.
"Person" contains all general data, stored in a global RecordStore. "PersonalInformation" contains editable Data i.e. images to be editable for each site separately. These data are stored in seperate RecordStores under each site.
That means within each site-template->Constants I've defined the extension-storagePid i.e.: $plugin.tx_myext.persistence.storagePid = 1
This config is on all sites the same, to be able to access the same RecordStore from each Site.
The RecordStore for "PersonalInformation" should be different for each site. So my setup.txt of my extension looks like:
persistence {
storagePid = {$plugin.tx_myext.persistence.storagePid},
{$plugin.tx_tx_myext.persistence.personalInformationStoragePid}
classes {
TYPO3\T3myext\Domain\Model\PersonalInformation {
newRecordStoragePid = {$plugin.tx_myext.persistence.personalInformationStoragePid}
}
}
}
And in my root-site-template under Constants I've defined plugin.tx_myext.persistence.personalInformationStoragePid for each site individually.
My TCA MM-Relation defined for PersonalInformation:
'person' => array(
'exclude' => 1,
'label' => 'LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_person',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'tx_myext_domain_model_person',
'foreign_table_where' => 'AND 1=1 ORDER BY last_name ASC',
'MM' => 'tx_myext_person_personalinformation_mm',
'size' => 10,
'autoSizeMax' => 30,
'maxitems' => 1,
'minitems' => 0,
'multiple' => 0,
),
),
My TCA MM-Relation defined for Person:
'personalinformation' => array(
'exclude' => 1,
'label' => 'LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_person.personalinformation',
'config' => array(
'type' => 'none',
'readonly' => 1,
'foreign_table' => 'tx_myext_domain_model_personalinformation',
'MM_opposite_field' => 'personalinformation',
'MM' => 'tx_myext_person_personalinformation_mm',
'foreign_table_where' => 'AND tx_myext_domain_model_personalinformation.pid=###The-PID-defined-in-my-site-Const-for-personalInformationStoragePid###'
),
),
If I var_dump my Person in the Frontend all Person.PersonaInformation of all RecordStores are displayed. But I what to show only PersonalInformation Records of the current Site.
The field in the model will always give back all relations, independent of the storage pid. The foreign_table_where in TCA is only for the backend, so this will do nothing for the frontend.
If you want to only get relations from a certain pid, there are several solutions:
Filter it yourself, either in your template, model or controller. Just loop through the relations and check the pid. This option is easiest, but will be slow if you have a lot of relations.
Select the PersonalInformation records separately in your controller using a PersonalInformationRepository with a findByPerson function. This will respect the storagePid set in TypoScript. This will work fine if you only need the information for 1 person. If you need it for multiple persons on 1 page (in a list view for example) you can do this in a custom getPersonalInformation function in your Person model. If it's not cached it could also be slow for lists (depending on the amount of records).
Use a completely custom query using QueryBuilder (https://docs.typo3.org/typo3cms/CoreApiReference/latest/ApiOverview/Database/QueryBuilder/Index.html). This way you can do it in 1 query with joins.
What is the best solution depends on your exact situation and the number of records.
In my own extension I have a bi-directional mm-relation between categories and items using an mm-table.
mm-table has 4 columns uid_local, uid_foreign, sorting, sorting_foreign.
TCA for both object tables is (only important parts)
categories table:
'items' => array(
'l10n_display' => 'defaultAsReadonly',
'l10n_mode' => 'exclude',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'tx_records_domain_model_item',
'foreign_table_where' => ' AND tx_records_domain_model_item.sys_language_uid = ###REC_FIELD_sys_language_uid###',
'MM' => 'tx_records_item_category_mm',
),
),
and items table
'categories' => array(
'exclude' => 0,
'l10n_display' => 'defaultAsReadonly',
'l10n_mode' => 'exclude',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'tx_records_domain_model_category',
'foreign_table_where' => ' AND tx_records_domain_model_category.sys_language_uid = ###REC_FIELD_sys_language_uid###',
'MM' => 'tx_records_item_category_mm',
'MM_opposite_field' => 'items',
),
),
I have 4 languages. Now for my problem.
I have a category with uid 7. The items are added and sorted in my select field. Output in front end is in the given order as set in the backend.
But now – when I update one of the items of the category that item will be placed before all other items in front end while the sorting in the back end is still as it was before the item's update. If i save the category afterwards, the front end will show the desired sorting again.
During my research I found that the mm table shows strange records. When the front end output is correct, I have one record per item in the category, and sorting is from 1 through 13.
After the item's update, I find three new records in the mm table. Three for three additional languages. These three records show my categories local_uid==7, foreign_uids are the uids of the localized item records, sorting_local is equal to 0 for all three records. I suggest this results in the wrong fornt end output although the primary language record still has the old sorting value. That's why it is shown correctly in the backend's category form.
Why do I find those 3 additional records after the item's update. The combination of the primary language's category uid with the localized uids of the items can not be correct.
Any suggestions?
I could make it work by setting l10n_mode => '' in the items table. To be honest, I do not exactly understand what happens there now, but it works.
Hint found on https://forge.typo3.org/issues/57272
I'm currently struggling with a m:m relation within a simple custom TYPO3 extension.
There are multiple filters and about a dozen of categories a filter can be related to. The relation consists of the category being selected within the filter:
Now, there are about 150 filters and all categories show all filters when assigning them to a product, but should only show those filters that are associated to that category.
I could not find any documentation about this, my current TCA setup looks like this:
'filter_bauwerkszustand' => array(
'exclude' => 0,
'label' => 'Bauwerkszustand',
'config' => array(
'type' => 'select',
'renderType' => 'selectMultipleSideBySide',
'foreign_table' => 'tx_produkte_domain_model_filter',
'foreign_table_where' => ' AND tx_produkte_domain_model_filter.filterkategorie = 1 AND tx_produkte_domain_model_filter.sys_language_uid=###REC_FIELD_sys_language_uid### ORDER BY tx_produkte_domain_model_filter.titel ASC',
'MM' => 'tx_produkte_filter_filterkategorie_mm',
'size' => 10,
'autoSizeMax' => 10,
'maxitems' => 9999,
'multiple' => 0,
),
),
If its a MM-relation thats the problem: the relation colum in filter doesnt acutally hold the categories, just the count of relations. The actual relations are reflected in a MM-table. The backend incorporates the categories in a SELECT statement with JOINs, first to the MM-table, and from there to the actual categories, like so:
tx_produkte_domain_model_filter.uid =
tx_produkte_filter_filterkategorie_mm.uid_local
tx_produkte_filter_filterkategorie_mm.uid_foreign =
tx_produkte_domain_model_filterkategorie.uid
Try relacing the tx_produkte_domain_model_filter.filterkategorie = 1 part in the query with tx_produkte_filter_filterkategorie_mm.uid_foreign = 1.
