/**
|
|
* TableField behaves in the same manner as TableListField, however allows the addition of
|
|
* fields and editing of attributes specified, and filtering results.
|
|
*
|
|
* Caution: If you insert DropdownFields in the fieldTypes-array, make sure they have an empty first option.
|
|
* Otherwise the saving can't determine if a new row should really be saved.
|
|
*
|
|
* Caution: TableField relies on {@FormResponse} to reload the field after it is saved.
|
|
* A TableField-instance should never be saved twice without reloading, because otherwise it
|
|
* can't determine if a field is new (=create) or existing (=update), and will produce duplicates.
|
|
*
|
|
* @param $name string The fieldname
|
|
* @param $sourceClass string The source class of this field
|
|
* @param $fieldList array An array of field headings of Fieldname => Heading Text (eg. heading1)
|
|
* @param $fieldTypes array An array of field types of fieldname => fieldType (eg. formfield). Do not use for extra data/hiddenfields.
|
|
* @param $filterField string The field to filter by. Give the filter value in $sourceFilter. The value will automatically be set on new records.
|
|
* @param $sourceFilter string If $filterField has a value, then this is the value to filter by. Otherwise, it is a SQL filter expression.
|
|
* @param $editExisting boolean (Note: Has to stay on this position for legacy reasons)
|
|
* @param $sourceSort string
|
|
* @param $sourceJoin string
|
|
*
|
|
* @todo We should refactor this to support a single FieldSet instead of evaluated Strings for building FormFields
|
|
*
|
|
* @package forms
|
|
* @subpackage fields-relational
