[英]Unable to insert data in mysql table

问题描述

我无法插入产品，并且警报脚本不起作用。 我正在尝试使用表单将一些数据插入数据库。 填写表格后，我使用method =“ POST”获取数据。 我没有语法错误，尽管我无法将表单中的数据插入数据库。 

<?php
    include("includes/db.php");
?>

仅一行错误。替换 

 <input type="submit" name="insert_product" value="Insert Product"/>

至 

<input type="submit" name="insert_product" value="Insert Product"/>

由于您已经检查过if（isset（$ _ POST [insert_product]））。 尝试代码 

<?php
include("includes/db.php");

您的提交按钮名称与isset（$ _ POST ['insert_product']）语句不同。
