使用下面的代码,我得到错误"Call to undefined method stdClass::fetchObject()"。
function getProdDetails2SaveInInvoice($data) {
global $dbh;
try {
$sth=$dbh->prepare("
SELECT
AES_DECRYPT('alt_id', ?),
AES_DECRYPT('prod_name', ?),
AES_DECRYPT('prod_desc', ?)
FROM
products
WHERE
prod_id = ?
");
$sth->execute($data);
$rs = $sth->query(PDO::FETCH_ASSOC);
return $rs;
}
catch(PDOException $e) {
echo "Something went wrong. Please report this error.\n";
file_put_contents(
$_SERVER['DOCUMENT_ROOT']."/PDOErrors.txt",
"\n\nScript name : ".SCRIPT."\nFunction name : ".__FUNCTION__."\n".
$e->getMessage(), FILE_APPEND);
throw new failedTransaction();
}
}
$data = array(
DBKEY, /* field 1 */
DBKEY, /* field 2 */
DBKEY, /* field 3 */
$prodid /* comparison */
);
$rs = getProdDetails2SaveInInvoice($data);
while ($row = $rs->fetchObject()) {
echo $row->prod_name;
}
不幸的是,这不起作用并返回上述错误。
我可以确认 $dbh 数据库连接正在工作,因为它与用于插入和更新的连接相同。谢谢。
更新
这就是我根据以下建议修改代码的方式,但我仍然没有得到任何返回:
try {
$dbh = new PDO("mysql:host=".CO_DB_HOST.";dbname=".CO_DB_NAME, CO_DB_UNAME, CO_DB_PWORD);
$dbh ->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch(PDOException $e) {
echo $e->getMessage();
}
function getProdDetails2SaveInInvoice($data) {
global $dbh;
try {
$sth=$dbh->prepare("
SELECT
AES_DECRYPT('alt_id', ?),
AES_DECRYPT('prod_name', ?),
AES_DECRYPT('prod_desc', ?)
FROM
products
WHERE
prod_id = ?
");
$sth->execute($data);
while ($row = $sth->fetchObject()) {
// PROCESS ROW
$rs = array($row->alt_id, $row->prod_name, $row->prod_desc);
}
return $rs;
}
catch(PDOException $e) {
echo "Something went wrong. Please report this error.\n";
file_put_contents(
$_SERVER['DOCUMENT_ROOT']."/PDOErrors.txt",
"\n\nScript name : ".SCRIPT."\nFunction name : ".__FUNCTION__."\n".
$e->getMessage(), FILE_APPEND);
throw new failedTransaction();
}
}
// Fetch additional info from invoice_products.
$data = array(
DBKEY, /* field 1 */
DBKEY, /* field 2 */
DBKEY, /* field 3 */
$prodid /* comparison */
);
$rs = getProdDetails2SaveInInvoice($data);
print_r($rs);
如果我硬编码 'where' 参数 (19),它仍然无法检索结果。理想情况下,我认为我应该在一个对象中检索结果,以便可以对其进行流式传输,但是现在,即使它装在盒子里,我也会很高兴!
数据肯定存在于数据库中,并且可以使用传统查询来提取。
这是 print_r($rs) 的输出:
数组( [0] => [1] => [2] => )
