title: SearchFilter Modifiers summary: Use suffixes on your ORM queries.
SearchFilter Modifiers
The filter and exclude operations specify exact matches by default. However, there are a number of suffixes that
you can put on field names to change this behavior. These are represented as SearchFilter subclasses and include.
- StartsWithFilter
- EndsWithFilter
- PartialMatchFilter
- GreaterThanFilter
- GreaterThanOrEqualFilter
- LessThanFilter
- LessThanOrEqualFilter
An example of a SearchFilter in use:
:::php
// fetch any player that starts with a S
$players = Player::get()->filter(array(
'FirstName:StartsWith' => 'S',
'PlayerNumber:GreaterThan' => '10'
));
// to fetch any player that's name contains the letter 'z'
$players = Player::get()->filterAny(array(
'FirstName:PartialMatch' => 'z',
'LastName:PartialMatch' => 'z'
));
Developers can define their own SearchFilter if needing to extend the ORM filter and exclude behaviors.
These suffixes can also take modifiers themselves. The modifiers currently supported are ":not", ":nocase" and
":case". These negate the filter, make it case-insensitive and make it case-sensitive, respectively. The default
comparison uses the database's default. For MySQL and MSSQL, this is case-insensitive. For PostgreSQL, this is
case-sensitive.
Note that all search filters (e.g. :PartialMatch) refer to services registered with Injector
within the DataListFilter. prefixed namespace. New filters can be registered using the below yml
config:
:::yaml
SilverStripe\Core\Injector\Injector:
DataListFilter.CustomMatch:
class: MyVendor/Search/CustomMatchFilter
The following is a query which will return everyone whose first name starts with "S", either lowercase or uppercase:
:::php
$players = Player::get()->filter(array(
'FirstName:StartsWith:nocase' => 'S'
));
// use :not to perform a converse operation to filter anything but a 'W'
$players = Player::get()->filter(array(
'FirstName:StartsWith:not' => 'W'
));
