我想在表中添加新项，同时将它们插入数据库mySQL。但是，当我单击"保存"时，它不会执行任何操作，也不会显示任何错误。我不知道哪一部分错了。

其他部分如编辑、删除没有问题。唯一的问题是添加新项目。无法将其插入数据库。
我的php代码
<?php
//include connection file
include_once("connect.php");
$db = new dbObj();
$connString = $db->getConnstring();
$params = $_REQUEST;
$action = isset($params['action']) != '' ? $params['action'] : '';
$empCls = new Item($connString);
switch($action) {
case 'add':
$empCls->insertItem($params);
break;
case 'edit':
$empCls->updateItem($params);
break;
case 'delete':
$empCls->deleteItem($params);
break;
default:
$empCls->getItem($params);
return;
}
class Item {
protected $conn;
protected $data = array();
function __construct($connString) {
$this->conn = $connString;
}
public function getItem($params) {
$this->data = $this->getRecords($params);
echo json_encode($this->data);
}
function insertItem($params) {
$data = array();
$sql = "INSERT INTO `itemchecklist` (itemCat, itemName, quantity)
VALUES('" . $params["category"] . "', '" . $params["name"] . "','" .
$params["quantity"] . "'); ";
echo $result = mysqli_query($this->conn, $sql) or die("error to insert
item data");
}
function getRecords($params) {
$rp = isset($params['rowCount']) ? $params['rowCount'] : 10;
if (isset($params['current'])) { $page = $params['current']; } else {
$page=1; };
$start_from = ($page-1) * $rp;
$sql = $sqlRec = $sqlTot = $where = '';
if( !empty($params['searchPhrase']) ) {
$where .=" WHERE ";
$where .=" ( itemCat LIKE '".$params['searchPhrase']."%' ";
$where .=" OR itemName LIKE '".$params['searchPhrase']."%' ";
$where .=" OR quantity LIKE '".$params['searchPhrase']."%' )";
}
if( !empty($params['sort']) ) {
$where .=" ORDER By ".key($params['sort']) .'
'.current($params['sort'])." ";
}
// getting total number records without any search
$sql = "SELECT * FROM `itemchecklist` ";
$sqlTot .= $sql;
$sqlRec .= $sql;
?>
我已经知道问题出在哪里了。首先，因为我没有在"添加"部分中包含"id"的参数
<input type="hidden" value="id" name="id" id="id">
然后，在修复后，我只能插入一行。这只是因为我没有在数据库mySQL中查询列"id"的"AUTO_INCREMENT"。不管怎样，谢谢你回答我的问题，先生，我是新手。
