Question

连接是正确的字段设置正确，但无法从代码中找到问题。一小时前它工作正常但是在放入更多字段之后它就卡住了。正确提交，但是xampp中的字段没有任何内容。请帮我提交数据。看看下面的变量，实际上是下面的所有代码。

 <?php 
  $product = "";
  $cost = "";
  $other = "";
  $otherOne = "";
  $code = "";
  $price = "";
  $qty  = "";
  $kg   = "";
  $value = "";
  $id = 0;

这是我的config.php文件代码，它与我的数据库正确连接，因为它无法显示任何die（）错误。

<?php 
 //Database Connection
 $host = 'localhost';
 $user = 'root';
 $pass = '';
 $db   = 'waqar';

 $connection = mysqli_connect($host, $user,$pass,$db) or die("<h2>Database Connection Failed. Contact Your Administrator</h2>");

?>

//表格提交时

if(isset($_POST['submit'])) {
  $product = $_POST['product'];
  $cost = $_POST['cost'];
  $other = $_POST['other'];
  $otherOne = $_POST['otherOne'];
  $code = $_POST['code'];
  $price = $_POST['price'];
  $qty  = $_POST['qty'];
  $kg   = $_POST['kg'];
  $value = $_POST['value']; 

  //Query
  $query = "INSERT INTO managment(product, cost, other, otherOne, code, price, value) VALUES ('$product','$cost','$other', '$otherOne', '$code', '$price', '$qty', '$kg', 'value')";
  mysqli_query($connection, $query);
  header("location: home.php");
  }
?>
<?php include("header.php"); ?>

您错过了价值$

$ query =“INSERT INTO管理（产品，成本，其他，其他，代码，价格，价值）VALUES（'$ product'，'$ cost'，'$ other'，'$ otherOne'，'$ code '，'$ price'，'$ qty'，'$ kg'，'$ value'）“;

我无法将表单数据提交到MySQL数据库
