1280 =item C<set_session_value @values>
1281 =item C<set_session_value %values>
1283 Store all values of C<@values> or C<%values> in the session. Each
1284 member of C<@values> is tested if it is a hash reference. If it is
1285 then it must contain the keys C<key> and C<value> and can optionally
1286 contain the key C<auto_restore>. In this case C<value> is associated
1287 with C<key> and restored to C<$::form> upon the next request
1288 automatically if C<auto_restore> is trueish or if C<value> is a scalar
1291 If the current member of C<@values> is not a hash reference then it
1292 will be used as the C<key> and the next entry of C<@values> is used as
1293 the C<value> to store. In this case setting C<auto_restore> is not
1296 Therefore the following two invocations are identical:
1298 $::auth-E<gt>set_session_value(name =E<gt> "Charlie");
1299 $::auth-E<gt>set_session_value({ key =E<gt> "name", value =E<gt> "Charlie" });
1301 All of these values are copied back into C<$::form> for the next
1302 request automatically if they're scalar values or if they have
1303 C<auto_restore> set to trueish.
1305 The values can be any Perl structure. They are stored as YAML dumps.
1307 =item C<get_session_value $key>
1309 Retrieve a value from the session. Returns C<undef> if the value
1312 =item C<create_unique_sesion_value $value, %params>
1314 Create a unique key in the session and store C<$value>
1317 Returns the key created in the session.
1319 =item C<save_session>
1321 Stores the session values in the database. This is the only function
1322 that actually stores stuff in the database. Neither the various
1323 setters nor the deleter access the database.
1325 =item <save_form_in_session %params>
1327 Stores the content of C<$params{form}> (default: C<$::form>) in the
1328 session using L</create_unique_sesion_value>.
1330 If C<$params{non_scalars}> is trueish then non-scalar values will be
1331 stored as well. Default is to only store scalar values.
1333 The following keys will never be saved: C<login>, C<password>,
1334 C<stylesheet>, C<titlebar>, C<version>. Additional keys not to save
1335 can be given as an array ref in C<$params{skip_keys}>.
1337 Returns the unique key under which the form is stored.
1339 =item <restore_form_from_session $key, %params>
1341 Restores the form from the session into C<$params{form}> (default:
1344 If C<$params{clobber}> is falsish then existing values with the same
1345 key in C<$params{form}> will not be overwritten. C<$params{clobber}>
