Question

我有这些变量：

$cliente = mysqli_real_escape_string($conn, htmlentities($_GET["cliente"]));
$metatickt = mysqli_real_escape_string($conn, htmlentities($_GET["metatickt"]));
$metaext = mysqli_real_escape_string($conn, htmlentities($_GET["metaext"]));
$metaenc = mysqli_real_escape_string($conn, htmlentities($_GET["metaenc"]));
$uf = mysqli_real_escape_string($conn, htmlentities($_GET["estado"]));

我正在尝试执行此查询：

$queryInst = "INSERT  meta_control (mes,cliente,meta_exit,meta_tickt,meta_enc,uf)"
          . " VALUES (MONTH(NOW()),'" . $cliente . "','" . $metaext . "','" . $metatickt . "','" . $metaenc . "','" . $uf . "')";
 mysqli_query($conn, $queryInst);

但是当我检查我的数据库时，唯一不为NULL的列是mes。可能是什么原因造成的？

Answer 1

您应该使用正确的查询。 INSERT INTO

$queryInst = "INSERT INTO meta_control (mes,cliente,meta_exit,meta_tickt,meta_enc,uf)"
              . " VALUES (MONTH(NOW()),'" . $cliente . "','" . $metaext . "','" . $metatickt . "','" . $metaenc . "','" . $uf . "')";
mysqli_query($conn, $queryInst);

Answer 2

您可能遇到SQL错误。您应该使用mysqli_error($conn) - http://php.net/manual/en/mysqli.error.php检查此类错误。在这种情况下，您可能会因SQL查询中缺少INTO关键字而导致错误，该关键字应为INSERT INTO .... http://dev.mysql.com/doc/refman/5.7/en/insert.html

PHP MySQL INSERT查询不插入所有值
