Question

我正在尝试将数据简单保存到数据库中。我有一个模态的表格。

当我尝试将数据保存到我的数据库时，它将无法保存。如果我将表单放在模态之外，它会将数据保存到数据库中。

我已经google了解决方案，但没有找到。提交按钮是我的形式，因此不会导致问题。

PHP代码：

<?php
ini_set('display_errors', 'On');   
error_reporting(E_ALL | E_STRICT); 

session_start();
include 'config.php';

if(!isset($_SESSION['user_id'])) {
    header("Location: login.php");
}

//read out data from db
$query_string = "SELECT * FROM tbl_Category";
$query = mysqli_query($con, $query_string);

//save data to db
if(isset($_POST['saveCategory'])){
  $category = mysqli_real_escape_string($con, $_POST['category']);
  $query = "INSERT INTO tbl_Category(category) VALUES('$category')"; 
  $result = mysqli_query($con, $query);

  if(!$result){
      echo mysqli_error();
  }
  else{
    $category = '';
    echo "YES";
  }
}

?>

我的config.php文件：

<?php
$con = mysqli_connect("localhost", "root", "root", "challenger") or die("Error " . mysqli_error($con));

// if($con){
//          echo"There is a connection";
//   }

?>

我的部分HTML代码：

 <!-- Page Content -->
 <div id="page-wrapper">
    <div class="container-fluid">
      <div class="row bg-title">
        <div class="col-lg-3 col-md-4 col-sm-4 col-xs-12">

                </tr>
              </thead>
              <tbody>
                <?php
                  while($row = mysqli_fetch_assoc($query)){
                    echo "<tr>";
                      echo "<td>".$row['category_id']."</td>";

                    echo "</tr>";  
                  }    
                ?>
              </tbody>

Answer 1

更改此

  $query = "INSERT INTO tbl_Category(category) VALUES('$category')";

到这个

  $query = "INSERT INTO tbl_Category(`category`) VALUES('$category')";

在模型中提交表单而不将数据保存到数据库
