Filter all fields and all rows in a recordset and returns the
|
|
processed recordset. We scroll to the beginning of the new recordset
|
|
after processing.
|
|
|
|
We pass a recordset and function name to RSFilter($rs,'rowfunc');
|
|
and the function will be called multiple times, once
|
|
for each row in the recordset. The function will be passed
|
|
an array containing one row repeatedly.
|
|
|
|
Example:
|
|
|
|
// ucwords() every element in the recordset
|
|
function do_ucwords(&$arr,$rs)
|
|
{
|
|
foreach($arr as $k => $v) {
|
|
$arr[$k] = ucwords($v);
|
|
}
|
|
}
|
|
$rs = RSFilter($rs,'do_ucwords');
|
|
*/
|
|

|

{

|
|
if (!$rs->connection) return false;
|
|

$rs = $rs->connection->_rs2rs($rs);

}
|

$rows = $rs->RecordCount();

for ($i=0; $i < $rows; $i++) {
