Contao 5.3 Fehler bei NodesPicker

hallo, ich versuche den NodesPicker in Contao5 bei News einzubinden. Dabei entsteht folgende Fehlermeldung.

[2024-02-22T18:45:06.769367+01:00] request.CRITICAL: Uncaught PHP Exception TypeError: "str_replace(): Argument #3 ($subject) must be of type array|string, null given" at NodePickerWidget.php line 81 {"exception":"[object] (TypeError(code: 0): str_replace(): Argument #3 ($subject) must be of type array|string, null given at /www/htdocs/w01e8696/editiondasausland.com/vendor/terminal42/contao-node/src/Widget/NodePickerWidget.php:81)"} {"request_uri":"https://editiondasausland.com/contao?act=edit&do=news&id=3&ref=7jsQEf_s&rt=14d4290fe45900d175d37411.txbhWfImz6mHmqN3OcaWkdaBUHdG1JCliRqpHsbGSCQ.42KYLogemfvs7tMca6fi3qzFCAMEtebi3XXnTf-LIneEQKwtsVOH0Oaskw&table=tl_news","request_method":"GET"}

Mein Code für die DCA sieht wie folgt aus

// Node
$GLOBALS['TL_DCA']['tl_news']['fields']['node'] = [
	'label'                   	=> &$GLOBALS['TL_LANG']['tl_news']['node'],
	'exclude' 					=> true,
	'inputType' 				=> 'nodePicker',
	'eval' 						=> ['multiple' => true, 'fieldType' => 'checkbox', 'tl_class' => 'clr', 'includeBlankOption' => true],
	'sql' 						=> ['type' => 'blob', 'notnull' => false],
];

Was soll ich machen, um dies zu beseitigen?

Error: Node of folder type cannot have content elements

I have a content node and inside there is a single text element with some content in it.

If I add a link to the text, everything works fine if I choose a "page" or a "file" with the picker. If I add a "news" element or an "event" element and save the content element, it will result to the error shown above. I guess it would be the same with a "faq" element.

The node it self is inside a node-folder, but it makes no difference if I move it outside a node folder. I have the latest contao-node version installed on a Contao 4.4.42 LTS.

Kind regards,
Sares

Show node name in article listing of content elements

If you add a content node as a content-element to your articles, it shows the content of the node's first content element in the listing as description. I think it would be better, if the "name" of the node would be displayed instead.

Hope it is clear what I mean :-)

If not:

• create a new content node
• name it f.e. "testnode" and add some content elements to it
• go to articles and add the testnode to an article
• in the listing you will see, that it will not show "Nodes -> testnode", but the content of the first generated content element, whatever it is f.ex. "Nodes -> Some text".

Kind regards,
Sares

Feature import/export

Schön wäre eine Import/Export Möglichkeit ala .cto zur Nutzung in versch. Installationen.
Wäre dies technisch überhaupt möglich?

The folder nodes are not allowed

If you select a node of type folder in content element "Nodes", you get this error: The folder nodes are not allowed. Should folders not be selectable then? Or is it something the picker currently cannot do? 🤔

Attempted to load class "Table" from the global namespace. Did you forget a "use" statement?

On a nearly empty 5.04 (e.g. Contao plus the Rocksolid theme stuff) I get the following back end error if I try to open the nodes menu:

Benutzergruppenverwaltung

Hallo,

leider kommt es derzeit zu einem Fehler, wenn ich die Benutzergruppen bearbeiten möchte. Ich nutze 1.5.10, Contao 4.13.14 und PHP 8.0.x

[2022-12-16T13:28:11.232150+01:00] request.CRITICAL: Uncaught PHP Exception Error: "Cannot create references to/from string offsets" at /homepages/u2652/www/contao4/var/cache/prod/contao/dca/tl_node.php line 13 {"exception":"[object] (Error(code: 0): Cannot create references to/from string offsets at /homepages/u2652/www/contao4/var/cache/prod/contao/dca/tl_node.php:13)"} []

Define filters for each node

I evaluating to replace psi/boxes4ward with this extension. Boxes4ward isn't maintained really actively that's why I'm looking for an alterantive.

With boxes4ward it is possible to select pages as white- or blacklist on which the nodes should be visible. Also inherit this setting to supages is possible.

Would you accept it as a feature? I'd provide a PR for it.

CSS-ID/Class settings are ignored

If you add a content-node to an article, it would be great, if you would check if there are some expert-settings available (CSS-ID/Classes) and output them to the frontend.

Right now the ce_nodes.html template only includes:

<?= implode("\n", $this->nodes) ?>

and therefore the CSS-ID/Class settings are ignored.
I like it, that nothing else is added to the output, but in this case I would expect an additional div container.

Best regards,
Sares

onNodesSaveCallback does not work with mandatory => false

If you have a DCA field like this:

'nodes' => [
    'label' => …,
    'exclude' => true,
    'inputType' => 'nodePicker',
    'eval' => ['mandatory' => false, 'multiple' => true, 'fieldType' => 'checkbox', 'tl_class' => 'clr'],
    'sql' => ['type' => 'blob', 'notnull' => false],
    'save_callback' => [
        ['terminal42_node.listener.content', 'onNodesSaveCallback'],
    ],
],

You'll run into the following error when saving without any defined nodes:

Argument 1 passed to Terminal42\NodeBundle\EventListener\ContentListener::onNodesSaveCallback() must be of the type string, null given, called in …\vendor\contao\core-bundle\src\Resources\contao\drivers\DC_Table.php on line 3111

Not sure what the best way to fix this is, without removing the string type of the first parameter of onNodesSaveCallback.

// edit: ah, we can simply use

public function onNodesSaveCallback(?string $value, DataContainer $dc): string

Error: Column not found: 1054 Unknown column 'tags' in 'field list'

While trying to save a new entry, this error appears:

An exception occurred while executing 'UPDATE tl_node SET tags=NULL WHERE id='1'': SQLSTATE[42S22]: Column not found: 1054 Unknown column 'tags' in 'field list'

Missing German translation: Access protection

The translation for label "Access protection" is missing.

Insert tags don't work in the templates

Unfortunately, both new insert tags don't work in the templates. I tried it in news_full.html5 and it didn't work. Can you check it, please? Thank you

Limit access of node content elements to specific user-groups

Nowadays, your articles often look like this:

-wrapper start
---grid start
-----text-element
---grid stop
---grid start
-----gallery-element
---grid stop
-wrapper stop
...

To have the possibility now to organize things like that in virtual folders and nodes is a big improvement and will reduce complexity in the articles-listing a lot.

However, normally, editors should only have access to the "inner" elements "text" and "gallery" in most cases, as shown in the example above. So maybe the bundle could be extended to define, if a content element should be visible / editable by a user/user-group or not.

If so, editing the node will result in a listing like this:

-----text-element
-----gallery-element

and the "complexity" of the outer structure will be hidden and a lot of admins would sleep much better I think :-)

What do you think?

Kind regards,
Sares

Add more options

Please add some more options to make the nodes a replacement for inserttags extension:

• Limit pages

• Show guests only

• Protect node

• Timing

• Condition

• Counter

Great would be the possibility to insert nodes directly in page layouts without having to create a module first and insert this module.

Add Pagination

If many nodes are displayed, an option for pagination, like other list modules (news, events...) would be useful.

Copy node doesn't copy content elements

I don't know if this is a bug or a non-existing feature :-)

If you make a copy of an existing node the included content elements are not copied and the new node has no content elements at all.

Contao 5.04: Non-existent service "session".

On a clean Contao 5.04 installation I get the following with Nodes v 1.5.11:
The service "terminal42_node.listener.data_container" has a dependency on a non-existent service "session". Did you mean one of these: "argument_resol ver.session", "session.storage.factory.native", "session_listener", "securi ty.authentication.session_strategy", "security.listener.session.contao_back end", "security.logout.listener.session.contao_backend", "security.listener .session.contao_frontend", "security.logout.listener.session.contao_fronten d", "contao.listener.clear_session_data", "contao.listener.user_session", " contao.session.factory", "contao.session.contao_backend", "contao.session.c ontao_frontend", "contao.session.factory.inner"?

Any clues for me?

German translation

I'd like to provide a PR for the German translation. However I wanted to ask what you prefer: do you want to translate the word "node" as well? Imho we could call it "node" in German too - because calling it "Knoten" everywhere sounds just awful ;)

Vererbung der Node Mounts wird nicht berücksichtigt

System:
CONTAO: 4.9.28
contao-node: 1.5.6

Beschreibung:
Wenn man einem Benutzer einen Mountpoint auf einen Ordner gibt und dieser anschließend den Fokus auf ein Inhaltsfragment legt, erscheint folgende Fehlermeldung:

An exception occurred while executing 'SELECT DISTINCT 'type' FROM tl_node WHERE id IN()': SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1

Schritte zum reproduzieren:

1. einen Ordner-Node anlegen
2. in diesem einen Inhalts-Node anlegen
3. einem Benutzer nur den Ordner-Node als Node-Mount geben
4. mit diesem Benutzer auf den Namen des Inhalts-Nodes klicken, um ihn zu "fokussieren"

Vermutlich beziehen sich die Bugs #27 und #28 ebenfalls auf dieses Verhalten. Zumindest ist die Fehlermeldung die gleiche.

Missing table after installation

As discussed with @richardhj, after installing contao-node, one have to update the database twice via the install tool. The table tl_cfg_tag_node is missing the first time.

Adding tags with leading number(s) will fail

I've tried to add some new content-node tags and run into a problem.

An exception occurred while executing 'INSERT INTO tl_cfg_tag_node (node_id, cfg_tag_id) VALUES ('38', '4-3s')': SQLSTATE[01000]: Warning: 1265 Data truncated for column 'cfg_tag_id' at row 1

I added something like this: 4-3s, but I also tried 2-grid etc. Seems, that leading numbers cause some insert problems.

Ability to select nodes in CTE and MOD by one (or multiple) tag names

What do you think about the possibility to not just use tags as a filter in the node selector but also the possibility to select one or multiple tags that will result in rendering all nodes with this tag in the frontend?

Seitenauswahl hinzufügen?

Besteht die Möglichkeit z. B. in der Node und/oder im Modul der Node eine Options-Gruppe für eine Seitenauswahl hinzuzufügen. So kann individuell bestimmt werden, auf welchen Seiten der Node ausgegeben wird und man benötigt keine zusätzlichen Seitenlayouts, um die Zuordnung zu regeln.

Add IDs in overview and alias for insert tags

May be it is a good idea in the overview of the nodes to show the IDs of the created nodes, so it might be easier to find the right node? I just placed some examples for the id labeling.

For an easier handling when inserted in the content it might be a good improvement also to establish an alias for the use in the insert tags?
