Question

我正在做一个报告目的的网站，所以我需要使用php将数据存储到MySQL。一切都很好，但我无法将整数/数字存储到数据库中。我想我的代码有问题。请帮帮我。

html代码：

 <div id = "forms">
   <form enctype="multipart/form-data" form action="add_data.php" method="post" >

  <li> <label for = "Injured_D" > No. of Injured Driver: </label>
  <input "type = "text" name = "Injured_D" id = "Injured_D" />  
  </li>

<div id = "submit"><button type="submit" >Submit</button> </div><br>
</form>

php代码：

// escape variables for security
$injured_D = mysqli_real_escape_string($con, $_POST['injured_D']);
$sql="INSERT INTO abc (injured_D) VALUES ('$injured_D')";

MySQL设置：

输入：int（30）

整理：无

Answer 1

你的代码中有拼写错误

<input "type = "text" name = "Injured_D" id = "Injured_D" />  
                              ^^

应该是

<input "type = "text" name = "injured_D" id = "Injured_D" />  
                              ^^

您在POST内传递 Injured_D ，并以名称 hurt_D 获取

Answer 2

更改

$sql="INSERT INTO abc (injured_D) VALUES ('$injured_D')";

到

$sql="INSERT INTO abc (injured_D) VALUES ($injured_D)";

Answer 3

$sql="INSERT INTO abc (injured_D) VALUES ('$injured_D')";

应该是

$sql="INSERT INTO abc (injured_D) VALUES ($injured_D)";

没有''

Answer 4

更改自：

$injured_D = mysqli_real_escape_string($con, $_POST['injured_D']);

致：

$injured_D = mysqli_real_escape_string($con, $_POST['Injured_D']);
