Question

我正在关注 PHP和MySQL中的电子商务网站的一些教程。 但是当我点击提交按钮时，我得到 OBJECT NOT FOUND ERROR。

以下是代码，请指导我。目录等都很好。我也尝试将该按钮括在单独的表单标签中，但没有任何效果。

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

Answer 1

尝试对你的表格动作加一个扩展名=“insert_product”...比如.php或.asp ..另外，将你的标题改为更像“在表单提交时找不到对象”。

试试这个：

<form method="post" enctype="multipart/form-data">

Answer 2

Ther有两个问题： -

问题是你写form只包含提交按钮。尝试在按钮之前删除<form method="post">
您在同一页面中编写了所有代码，但在表单中，您的操作是insert_product，其中没有.php这样的扩展名。这是完全错误的所以尝试做这两个中的任何一个。

a)或者定义它action= insert_product.php并创建一个具有该名称的文件，并将最后一个表单处理代码放在该文件中。

b)或删除表单action属性并写为<form method="post" enctype="multipart/form-data">。

一次尝试1点和2点b)点。并检查一次。

当我按下提交按钮时，尝试每件事但仍然在Xamp中找不到OBJECT NOT FOUND错误？
