The created (created_time), modified_by, modified (modified_time) are not populated/updated

[nkamp]

Hello,

I'm busy with a custom component and I want to show the user the four fields:

• created_by
  created (or created_time)
  modified_by
  modified (or modified_time)

If I save the details page (edit.php), than these values are not updated in the database. I have tried this with defining these fields in the <form>.xml and without defining these fields.

My question is, are these fields saved by default or not?
And if I want to modify the value's for a certain reason, were can I do this? In one of the methods of the tables file?

I've been looking at com_categories and com_content but I can't find it how and were these fields are maintained.

Yes the fields are saved default.

To change the values, click the tab labeled Publishing when posting an article

Ok, I’m doubting.
I’m busy to make a custom component and I have made views, but the fields created (or created_time), modified_by and modified (or modified_time) are not populated in the database. Created_by is populated in the database, if I do not define as read only in <form>.xml.

Make no difference if I define the fields in the <form>.xml or not, in both situations the values are not set in the database.

And if I define the fields in the <form>.xml as read only, the fields are in $data array but without value! I don’t understand why.
Or the fields modified_by/modified are filled somewhere in the code after the user has pressed ‘save’, but we’re? I can’t find we’re it is done at com_content/com_categories.

I try to find were the record is saved. I suppose that thre is somewhere an ‘insert’ or ‘update’ statement. I’m expecting in jmodeladmin, but till now I couldn’t find it.

I assume this means you are developing a component. Is a database table included? If yes, your form will need to send data to columns included within your table - `modified_by`, `created_by` and the other columns.

Are you fully capable of component writing? If not, see https://docs.joomla.org/J3.x:Developing ... _Component

Hello,

I'm following the tutorials of Robbie Jackson. At this moment I have not seen all of them, but I'm following these.

Although it's a thread of 2012 I have found viewtopic.php?t=750048.

And someone send an example from his component to show me something else, and I saw there that he put these in the function check. But it doesn't work as expected.

I have added this, and now these fields are populated in the database!!!

So I'm still doubting if these fields are populated by default! And I'm agree with all of you, I can't find this for the com_content or com_categories.
So it is still not clear how it should work or what the default behavior is for these fields.

Nico.

Is your component attempting to store data withing the _content table or its own table? Please clarify where the data is being sent.

I thought that it was clear that I have written in first message that I'm building a custom component. That said I thought that it is clear that the data is written to own tables.

Everything is custom made and the basic is from the book "Learning Joomla 3 Extension Development".

But in this particular case I'm looking at com_content and com_categories how they did it, but that is not clear to me.

But what is does it make the difference if it is written to com_content table or to a custom table?
