[TYPO3-dev] Changing TCA for certain BE users/groups

[Steffen Müller]

Hi.

I am looking for a way to alter TCA on a BE users/groups base.

The solution I have looks a bit oversized to me, so I'm asking you, if
there's a smarter way which does the trick?

In the example below, there's an extension with a field 'myfield' in
table 'my_ext_tbl'. The field is visible for all BE users, but
readOnly=1 is the default value in tca.php. Only a special group (or
admin) should be allowed to edit this field.

The following code is added to ext_tables.php:

if (!is_object($GLOBALS['BE_USER'])) {
  // Create new backend user object
  $GLOBALS['BE_USER'] = t3lib_div::makeInstance('t3lib_beUserAuth');
  // Initialize backend user object and load group information
  $GLOBALS['BE_USER']->start();   // Object is initialized
  $GLOBALS['BE_USER']->backendCheckLogin();
}

// is user admin?
if ($GLOBALS['BE_USER']->isAdmin()) {
  t3lib_div::loadTCA('tx_pumtravel_tours');
  // allow editing of field myfield in table myext_tbl
  $TCA['tx_myext_tbl']['columns']['myfield']['config']['readOnly'] = 0;
}

Any suggestions?
