Return the database schema used by this Fieldtype
Should return an array like in the example below, indexed by field name with type details as the value (as it would be in an SQL statement).
Indexes are passed through with a
keys
array. Note thatpages_id
as a field and primary key may be retrieved by starting with the parent schema return from the built-in getDatabaseSchema() method.At minimum, each Fieldtype must add a
data
field as well as an index for it.If you want a PHP
NULL
value to become a NULL in the database, your column definition must specify:DEFAULT NULL
.
Example
array(
'data' => 'mediumtext NOT NULL',
'keys' => array(
'primary' => 'PRIMARY KEY (`pages_id`)',
'FULLTEXT KEY data (data)',
),
'xtra' => array(
// optional extras, MySQL defaults will be used if omitted
'append' =>
'ENGINE={$this->config->dbEngine} ' .
'DEFAULT CHARSET={$this->config->dbCharset}'
// true (default) if this schema provides all storage for this fieldtype.
// false if other storage is involved with this fieldtype, beyond this schema
// (like repeaters, PageTable, etc.)
'all' => true,
)
);
Usage
$array = $fieldtypePageTable->getDatabaseSchema(Field $field);
