| 16 | Filter all fields and all rows in a recordset and returns the |
---|
| 17 | processed recordset. We scroll to the beginning of the new recordset |
---|
| 18 | after processing. |
---|
| 19 | |
---|
| 20 | We pass a recordset and function name to RSFilter($rs,'rowfunc'); |
---|
| 21 | and the function will be called multiple times, once |
---|
| 22 | for each row in the recordset. The function will be passed |
---|
| 23 | an array containing one row repeatedly. |
---|
| 24 | |
---|
| 25 | Example: |
---|
| 26 | |
---|
| 27 | // ucwords() every element in the recordset |
---|
| 28 | function do_ucwords(&$arr,$rs) |
---|
| 29 | { |
---|
| 30 | foreach($arr as $k => $v) { |
---|
| 31 | $arr[$k] = ucwords($v); |
---|
| 32 | } |
---|
| 33 | } |
---|
| 34 | $rs = RSFilter($rs,'do_ucwords'); |
