Hide specific fields based on checkbox in record

I’m having trouble finding where to set this - either in an Application delegate, or in an ini file.

As an example, I have a table… it contains 10 columns. 4 columns are public, and 5 are private if the user wants them to be. The user checks a checkbox if they want to show those 4 columns. If not, a helpful message “Not shown” should display.

Is this an ini setting, or in the delegate? Or is this beyond what xataface can provide without modifying core files?

Thanks!

OK, I think I am on the right track, though I wish this is something I could set in an ini file.

It looks like I’m going to have to create two functions, both set in the table delegate class:

1) fieldname__permissions
2) fieldname__display

What is the structure of $record?

I feel like a fool… but want to post my solution. This function goes in the table delegate:

Code: Select all

function fieldname__display(&$record) {       if ($record->_values['ShowColumn'] == 1) {          return $record->_values['fieldname'];       } else {          return 'Informaton Witheld';       }    }

Thats it. I’ll probably write this to be a bit more generic so I can apply this routine to several columns which need hiding.

The display() method is already subject to the “view” permission. If you deny users permission to that field, then display() will show “NO ACCESS”

Code: Select all

function fieldname__permissions($record){     if ( /* don't show this field */){         return array('view'=>0);     }     return null; }
