Question

I need to show author details on a page.

Here is my typoscript to get the cruser_id of the page content:

    20 = CONTENT
    20{
        table = tt_content
        select{
         selectFields = cruser_id
        }
        renderObj = COA
        renderObj{
         10 = TEXT  
         10{
         required=1      
         field=cruser_id
         }
        }
      }

How to get the username associated with the cruser_id?

Answer 1

As you didn’t specify the context of your code, here’s an example that just extends the code you provided.

20 = CONTENT
20 {
  table = tt_content
  select {
    selectFields = cruser_id
  }
  renderObj = RECORDS
  renderObj {
    source.field = cruser_id 
    tables = be_users
    dontCheckPid = 1
    conf.be_users = TEXT
    conf.be_users {
      field = username
      noTrimWrap = || |
    }
  }
}

EXPLANATION: You are fetching the content using the CONTENT cObject and telling TYPO3 to render it as RECORDS cObject. This object now has user’s UID available as cruser_id and can use it in its configuration using the source.field. RECORDS thus loads the record (with UID = cruser_id) from the be_users table and you tell TYPO3 to render it as a TEXT cObject. As it can be any cObject (e.g. COA), the output can be more complex, including other fields from the backend user’s record.

More complex example

20 = CONTENT
20 {
  table = tt_content
  select {
    selectFields = cruser_id, tstamp
  }
  renderObj = COA
  renderObj {
    10 = TEXT
    10 {
      field = tstamp
      date = j/n/Y
      noTrimWrap = |Last modified: ||
    }

    20 = RECORDS
    20 {
      source.field = cruser_id 
      tables = be_users
      dontCheckPid = 1
      conf.be_users = COA
      conf.be_users {
        stdWrap.noTrimWrap = |<br />Author: ||

        10 = TEXT
        10 {
          field = realName
        }

        20 = TEXT
        20 {
          field = username
          noTrimWrap = | (|)|
        }
      }
    }
  }
}
