如何使用 php 将整数存储到 MySQL 数据库？

Question

我正在做一个用于某些报告目的的网站，因此我需要使用 php 将数据存储到 MySQL。一切都很好，但我无法将 integers/numbers 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：

类型：整数(30)

整理：none

Answer 1

改变

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

至

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

Answer 2

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

应该是

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

没有' '

Answer 3

您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 并使用名称 injured_D

Answer 4

更改自：

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

收件人：

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