=head2 new |
| 355 |
|
| 356 |
Create a new Koha::AdditionalField object. This method can be called using several ways. |
| 357 |
Either with the id for existing field or with different values for a new one. |
| 358 |
|
| 359 |
=over 4 |
| 360 |
|
| 361 |
=item B<id> |
| 362 |
|
| 363 |
The caller just knows the id of the additional field and want to retrieve all values. |
| 364 |
|
| 365 |
=item B<tablename, name, authorised_value_category, marcfield and searchable> |
| 366 |
|
| 367 |
The caller wants to create a new additional field. |

The information will be retrieved from the database. |
| 374 |
|
| 375 |
=head2 update |
| 376 |
|
| 377 |
If the AdditionalField object has been modified and the values have to be modified into the database, call this method. |
| 378 |
|
| 379 |
=head2 delete |
| 380 |
|
| 381 |
Remove a the record in the database using the id the object. |

Insert a new AdditionalField object into the database. |
| 386 |
|
| 387 |
=head2 insert_values |
| 388 |
|
| 389 |
Insert new values for a record. |
| 390 |
|
| 391 |
my $af = Koha::AdditionalField({ id => $id })->fetch; |
| 392 |
my $af->{values} = { |

}; |
| 396 |
$af->insert_values; |
| 397 |
|
| 398 |
=head2 fetch_values |
| 399 |
|
| 400 |
Retrieve values from the database for a given record_id. |

| 405 |
|
| 406 |
$values will be equal to something like: |
| 407 |
{ |
| 408 |
record_id => { |
| 409 |
field_name1 => 'value1', |
| 410 |
field_name2 => 'value2', |
