using active record (delete)

[eluser]kikz4life[/eluser]
it worked! haha., thanks a many cahva..

also could you help me about using the CI active record update

Code:

case $crudConfig['update']:
                $sql = 'update '.$crudTableName.' set ';
                foreach($crudColumns as $key => $value){ $updateArray[$key] = $value.'='.$crudColumnValues[$key]; };
                $sql .= implode(',',$updateArray);
                $sql .= ' where role_id = '.$crudColumnValues['id'];
                mysql_query( $sql );
                break;

also how can i rewrite this part of the code to CI
foreach($crudColumns as $key => $value){ $updateArray[$key] = $value.'='.$crudColumnValues[$key]; };
                $sql .= implode(',',$updateArray);

for the update i've read the manual, but the above code seems a little more complex for me. Also i would like to ask the differences of => to =. From my thoughts "=>" means of the array and for "=" will return strings. Am i right? Sorry for this .
