This is a FORMidable data handler that can also handle m:n relations.

| tx_dhdbmm::_doTheMagic | ( | $ | bShouldProcess = TRUE |
) |
Takes the entered form data and inserts/updates it in the DB, using the table name set in /control/datahandler/tablename. For fields that have a m:n table defined in $this->mmFields, a real m:n relation is created instead of a comma-separated list of foreign keys.
This function can insert new records and update existing records.
This function is an exact copy of tx_dhdb with the following calls added:
| boolean | whether the data should be processed at all |

| tx_dhdbmm::_getStoredData | ( | $ | sName = false |
) |
Retrieves the data of the current record from the DB as an associative array. m:n relations are returned as a comma-separated list of UIDs.
This function calls _retrieveMmFields, so there is no need to call it before calling this function.
| boolean | (not sure what this is, but FORMidable 0.7.0 has it) |

| tx_dhdbmm::_retrieveMmFields | ( | ) |
Retrieves the keys and MM table names for m:n relations as key/value pairs and stores them in $this->mmFields in the following form:
field key => name of the m:n table
The data will be retrieved from the datahandler in the XML file where it needs to be stored in the following format:
<mmrelations> <relation field="place" mmtable="tx_seminars_seminars_place_mm"> <relation field="speakers" mmtable="tx_seminars_seminars_speakers_mm"> </mmrelations>
If $this->mmFields has already been set, this function will be a no-op.

| tx_dhdbmm::_extractMmRelationsFromFormData | ( | &$ | formData | ) |
Iterates over the form data in $formData and processes the fields that are marked as m:n relations the following way: 1. For each entry in the comma-separated list of values, an element in $this->mmInserts is created. 2. The comma-separated list will be converted to an integer containing the number of relations for this field.
This function calls _retrieveMmFields, so there is no need to call it before calling this function.
After this function has been called, $this->mmInsersts will not be null, but might be empty.
| array | the current form data (must not be empty or null), will be modified |

| tx_dhdbmm::_storeMmRelations | ( | $ | uid | ) |
Takes the m:n relations stored in $this->mmInserts and stores them in the DB with $uid as the local key. All previous relations for that key will be removed.
Before this function may be called, _extractMmRelationsFromFormData() must have been called.
| integer | the uid of the current record, must be > 0 |

Array containing the data to insert into m:n tables using the following format for each element:
'table' => name of the m:n table, 'data' => array( 'sorting' => the sorting position, 'uid_foreign' => the foreign key )
