查询不会插入但没有错误

Question

我要用我的代码完成的工作是，它首先检查代码是否正确，然后必须插入查询。但是不知何故，它不会插入...而且我不知道我一眼看错了什么。

我的PHP：

include 'functions/conn.php';
$Giveaway = "SELECT `content` FROM `sub_codes` WHERE `current_uses` > '0'";
$result1 = mysqli_query($conn, $Giveaway);
$row = mysqli_fetch_array($result1);
    if ($_POST['Code']===$row) {
        $sql3 = "SELECT `user_id` FROM `users` ORDER BY `user_id` DESC LIMIT 1";
        $result3 = mysqli_query($conn, $sql3);
        $row3 = mysqli_fetch_array($result3);
        $_start_date = date('Y-m-d');
        $_end_date = $row2;
        $sql2 = "SELECT `end_date` FROM `sub_codes` WHERE `content` = '".$_POST['Code']."'";
        $result2 = mysqli_query($conn, $sql2);
        $row2 = mysqli_fetch_array($result2);
        $sql = "INSERT INTO `partner_subscriptions` SET `user_id` = '$row3' + 1, `sub_id` = '99', `allowed_users` = '100', `start_date` = '$_start_date', `end_date` = '$row2';";
        if ($conn->query($sql) === TRUE) {
            echo "New record created successfully";
        } else {
            echo "Error: " . $sql . "<br>" . $conn->error;
        }
} else {
    echo "Wrong code";
}

还有我的html：

<br/><div class="form-group">
  <label title="Required">Free description code:</label>
    <input type="Code" name="Code" class="form-control" id="Code"
      required="true"/>
    </div><br/>

这是我到目前为止尝试过的。如果您需要更多代码，请问我。但是我认为这就足够了。我没有任何错误。

这是我插入页面的剩余代码

Answer 1

$ row2 = mysqli_fetch_array（$ result2）; //将产生一个数组，我希望 请验证end_date ='$ row2';插入查询中的..部分，以便传递确切的日期（或日期格式）

Answer 2

include 'functions/conn.php';
$Giveaway = "SELECT `content` FROM `sub_codes` WHERE `current_uses` > '0'";
$result1 = mysqli_query($conn, $Giveaway);
$row = mysqli_fetch_array($result1);

  //here $row is an array , you have to use $row['content']
  if ($_POST['Code']===$row['content']) {

      $sql3 = "SELECT `user_id` FROM `users` ORDER BY `user_id` DESC LIMIT 1";
      $result3 = mysqli_query($conn, $sql3);
      $row3 = mysqli_fetch_array($result3);
      $_start_date = date('Y-m-d');

      //$_end_date = $row2;
      //$row is not yet defined so move this line after $row2;

      $sql2 = "SELECT `end_date` FROM `sub_codes` WHERE `content` = '".$_POST['Code']."'";
      $result2 = mysqli_query($conn, $sql2);
      $row2 = mysqli_fetch_array($result2);

      //again $row2 is an array use $row2['end_date']
      $_end_date = $row2['end_date'];
      $user_id = $row3['user_id'] + 1;
      $sql = "INSERT INTO `partner_subscriptions` SET `user_id` = $user_id, `sub_id` = '99', `allowed_users` = '100', `start_date` = '$_start_date', `end_date` = '$_end_date';";

      if ($conn->query($sql) === TRUE) {
          echo "New record created successfully";
