[TYPO3-english] [Polluriel potentiel] More than one fe_users records with the same username possible?

[jean-sebastien_gervais at ssss.gouv.qc.ca]

Hello Roland 

According to the TCA, fe_users.username is unique by page id  (TYPO3 
4.5.x)  and the only unique constraint in the database is the uid. 

in other word, I guess that removing uniqueInPid in the TCA in this line 
would fix the issue for you.   add it to extTables.php : 
$TCA['fe_users']['columns']['username']['config']['eval'] = 
'nospace,lower,uniqueInPid,required';
 

For the unique user/password combination,  I don't think it is possible 
directly in the TCA, although you can use a user_func with the eval 
section, exemple: 
$TCA['fe_users']['columns']['username']['config']['eval']  = '
tx_exampleextraevaluations_extraeval1'

«You can supply your own form evaluations in an extension by creating a 
class with two functions, 
one which returns the JavaScript code for client side validation called 
returnFieldJS() 
and one which does the server side validation called evaluateFieldValue().
The function evaluateFieldValue() has 3 arguments:
1.      $value :The field value to be evaluated.
2.      $is_in : The "is_in" value of the field configuration from TCA 
(see below).
3.      &$set : Boolean defining if the value is written to the database 
or not. Must be passed by reference and changed if needed.
Example:
class.tx_exampleextraevaluations_extraeval1.php:
<?php
class tx_exampleextraevaluations_extraeval1 {
  function returnFieldJS() {
return ' return value + " [added by JS]";  ';
}
function evaluateFieldValue($value, $is_in, &$set) {
   return $value . ' [added by PHP]'; 
  }
}
?>
