我试图插入来自$ _POST表单的多个数组,但是即使尝试使用诸如“ while()”和“ foreach()”之类的方法,我也没有成功。这是我第一次使用数组执行此操作,所以我很迷茫。我的代码是:<input type='text' id="productName[]" name="productName[]"><input type='text' id="quantity[]" name="quantity[]">include_once("connection.php"); $name = $_POST['productName']; $quantity = $_POST['quantity'];$name = '"' . implode('","', $name) . '"';$quantity = '"' . implode('","', $quantity) . '"';$sql = "SELECT * FROM product WHERE name IN ($name)";$result = mysqli_query($conn_app, $sql);if (mysqli_affected_rows($conn_app) > 0){ while($row = mysqli_fetch_assoc($result)){ $itemId = $row['product_id']; };$insert = "INSERT INTO item_box (quantity,product_id) VALUES ('$quantity','$itemId')";$result = mysqli_query($conn_app, $insert);我希望结果为每个存在的数组插入行。喜欢:"INSERT INTO item_box (quantity,product_id) VALUES ("20","3")";"INSERT INTO item_box (quantity,product_id) VALUES ("50","5")";...但我得到一个错误结果(许多数量值和一个product_id),例如:"INSERT INTO item_box (quantity,product_id) VALUES ("20","30","40","50","2")"

您可以使用单个查询中使用多个数组
INSERT INTO a VALUES (1,23),(2,34),(4,33);
INSERT INTO a VALUES (8,26),(6,29);
