XF 2.0 Create a custom Nodes field (How to get the new field in database?)

[TheMainStreamer]

Hey, guys,
I have a little problem right now.....
I tried to add a new field to "nodes" in the admin interface, so that I can write something into a text box and use it as a variable for each category/forum.

Adding a new field wasn't that hard. I simply created a macro for the new field "background" in the "node_edit_macros" template

<xf:macro name="background" arg-node="!">
    <xf:textboxrow name="node[background]" value="{$node.background}" label="{{ phrase('node_background') }}" />
</xf:macro>

and then linked this macro in the "forum_edit" template

<xf:macro template="node_edit_macros" name="background" arg-node="{$node}" />

. So the first step was taken. Now an error message appeared, which I could fix by adding a "background" function into the "Node.php" which is in the path /src/XF/Entity/.

Everything now looks as if it could work, but the text I enter in the field does not save itself. This is also relatively logical, since no new entry has been created in the database. After several tests, this error message appeared:

I think the problem seems to be that no new field was created in the database....
Can you give me a hint what I did wrong or what I have to add in order for the field to appear in the database?

Thank you!
Justus

Did you alter the xf_node table?

 

[TheMainStreamer]

Haha thanks for your answer.. seems so that you are the only one who can help me every time ^^
mm yes I've created the row in xf_node table and if i add some text via the database the text get's displayed in the field in the xenforo interface... The Problem is that I can't save something in the Interface so if I wrote something in the field and hit the save button the text doesn't get saved...

Remove the default => '' part from your node entity

 

[TheMainStreamer]

If I remove the default => '' from my Node.php from 'background' => ['type' => self::STR, 'default' => ''] to 'background' => ['type' => self::STR]
I'm getting a error code that the default value is not defined:

Any other ideas?
Thanks!

You are making this in a add-on or editing the core files?
Did you do this part of the tutorial?

[TheMainStreamer]

Firstly I've tried to make it with the tutorial so create a addon but i didn't got it working, because of that I've eddited the core files like i described in #1 . Nearly everything works (Connection to the database ...) the only Problem is that I can't save it throught the xenforo interface. (So the input in the field doesn't get written into the database) But if I put something in the field via the database it works fine and gets displayed in the xenforo interface.

You need edit the file src/XF/Admin/Controller/Forum.php
Edit the protected function saveTypeData

 

[TheMainStreamer]

That seems to be the right way! Already thought about that but didn't found the function...
Thanks!

Can you give me a little hint what I have to add there? (Thought about something like the code in the tutorial but it didn't worked...
