/* |
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'); |
*/ |
function &RSFilter($rs,$fn) |
{ |
if ($rs->databaseType != 'array') { |
if (!$rs->connection) return false; |
|
$rs = &$rs->connection->_rs2rs($rs); |
} |
$rows = $rs->RecordCount(); |
for ($i=0; $i < $rows; $i++) { |
if (is_array ($fn)) { |
$obj = $fn[0]; |
$method = $fn[1]; |
$obj->$method ($rs->_array[$i],$rs); |
} else { |
$fn($rs->_array[$i],$rs); |
} |
|
} |
if (!$rs->EOF) { |
$rs->_currentRow = 0; |
$rs->fields = $rs->_array[0]; |
} |
|
return $rs; |
