Php Codeigniter将数据插入数据库

无法将数据插入mysql数据库。我把错误的代码弄糊涂了。我是Codeigniter的新手，不知道如何解决这个问题

下图tambah_berita.php

<form name="form" action="<?php echo base_url();?>index.php/admin/berita/tambah_berita" method="post">

请帮我做什么。谢谢

请使用以下表达式：

echo form_open('admin/berita/tambah_berita');

而不是

<form name="form" action="<?php echo base_url();?>index.php/admin/berita/tambah_berita" method="post">

您有任何错误或其他东西并打印（$data）打印数据或没有打印数据，您会遇到什么错误？仔细查看表单的操作url:

action=“index.php/admin/berita/tambah\u berita”

没有错误，但是当我打印（$data）时，结果是空的。您的表单重定向到您的控制器tambah\u berita对不起。我是新手，我不知道如何重定向到您的控制器tambah\u berita。你能告诉我怎么做吗？
