无法在mysql表中插入数据

标签： php forms mysqli insert

我无法插入产品，警报脚本也无效。我试图使用表单将一些数据插入到我的数据库中。填写表格后，我正在使用方法=＆＃34; POST＆＃34;。虽然我无法将表单中的数据插入到数据库中，但我没有语法错误。 

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

只有一行错误。放置

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

到

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

因为您已检查过（isset（$ _ POST [insert_product]））。试试代码

include("includes/db.php");

您的提交按钮名称与您的isset（$ _ POST [＆＃39; insert_product＆＃39;]）语句不同。
