Creates an INSERT SQL-statement for $table from the array with field/value pairs $fields_values. Usage count/core: 4

Parameters:

ux_t3lib_DB::map_assocArray (  $  input,
$  tables,
$  rev = FALSE
) 
 

Takes an associated array with field => value pairs and remaps the field names if configured for this table in $this->mapping array. Be careful not to map a field name to another existing fields name (although you can use this to swap fieldnames of course...:-) Observe mapping problems with join-results (more than one table): Joined queries should always prefix the table name to avoid problems with this. Observe that alias fields are not mapped of course (should not be a problem though)

Parameters:
array Input array, associative keys
array Array of tables from the query. Normally just one table; many tables in case of a join. NOTICE: for multiple tables (with joins) there MIGHT occur trouble with fields of the same name in the two tables: This function traverses the mapping information for BOTH tables and applies mapping without checking from which table the field really came!
boolean If true, reverse direction. Default direction is to map an array going INTO the database (thus mapping TYPO3 fieldnames to PHYSICAL field names!)
Returns:
array Output array, with mapped associative keys.
