form_open() not working in codeigniter
提问by Nitish
I am trying to build a simple form in CodeIgniter. My VIEW 'input_view.php' is:
我正在尝试在 CodeIgniter 中构建一个简单的表单。我的 VIEW 'input_view.php' 是：
<html>
<head>
<link rel="stylesheet" type="text/css" href="<?php echo "$base/$css"?>">
</head>
<body>
<div id="header">
<?php $this->load->view('books_header'); ?>
</div>
<div id="menu">
<?php $this->load->view('books_menu'); ?>
</div>
<?php //echo $title; ?>
<?php echo form_open('books/input'); ?>
<?php echo $title; ?>
<?php echo form_input('title'); ?>;
<?php echo $author; ?>
<?php echo form_input('author'); ?>
<?php echo $publisher; ?>
<?php echo form_input('publisher'); ?>
<?php echo $year; ?>
<?php echo form_dropdown('year',$years); ?>
<?php echo $available; ?>
<?php echo form_checkbox('available','yes',TRUE); ?>
<?php echo $summery; ?>
<?php echo form_textarea('summery'); ?>
<?php echo form_submit('mysubmit', 'Submit'); ?>
<?php echo form_close(); ?>
<div id="footer">
<?php $this->load->view('books_footer'); ?>
</div>
</body>
</html>
But when I tried http://localhost/CodeIgniter/index.php/books/input, it does not show the form, instead shows page upto menu. Whats the problem here?
但是当我尝试时http://localhost/CodeIgniter/index.php/books/input，它不显示表单，而是显示 page upto menu。这里有什么问题？

Did you load form helper in your controller where you call your simple form view?????
您是否在控制器中加载了表单助手，在那里您调用了简单的表单视图？？？？
$this->load->helper('form');
回答by prasobh
You must load helper file form for form usage on codigniter like this.
您必须像这样在 codgniter 上加载辅助文件表单以供表单使用。
$this->load->helper('form');
回答by Reinstar
Refer to CodeIgniter User Guide, you must load form helper before do it like this
请参阅CodeIgniter User Guide，您必须先加载表单助手，然后才能这样做
$this->load->helper('form');
You may put that syntax on your Controller or at top of your View before you use form_open, form_input or anything else.
在使用 form_open、form_input 或其他任何东西之前，您可以将该语法放在控制器上或视图顶部。

$this->load->helper('form');
in view page
在视图页面
or autoload the file go to application/config/autoload
或自动加载文件去应用程序/配置/自动加载
there you will find
在那里你会发现
$autoload['helper'] = array('');
$autoload['helper'] = array('form');
//input from helper it will allow in both view and controller page
