Codeigniter button redirect
提问by user3051523
I just want to ask because I'm working on Codeigniter and I'm have a button in home page wherein if click, it will page redirect to registration page.
我只是想问一下，因为我正在使用 Codeigniter 并且我在主页上有一个按钮，如果点击，它会将页面重定向到注册页面。
<input type='button' onClick='<?php redirect(base_url() . 'register/index'); ?>' />
I also tried the form helper.
我也尝试了表单助手。
<body>
<?php
$data = array('register' => array('name' => 'register',
'id' => 'register',
'value' => 'TRUE',
'type' => 'button',
'content' => 'Register',
'onClick' => redirect(base_url() . 'register/index')
);
?>
<table border="1">
<tr>
<td><?php echo form_button(element('register', $data, )); ?></td>
<td></td>
</tr>
</table>
</body>
The problem is nothing happens when I try to click the button.
问题是当我尝试单击按钮时没有任何反应。

CodeIgniter's redirect() function means to make a HTTP 302response, which only works before content being outputted. It's designed for controller and should never appear in your views.
CodeIgniter 的redirect() 函数意味着做一个HTTP 302响应，它只在内容被输出之前起作用。它是为控制器设计的，不应出现在您的视图中。
Navigation in browser-side can be implemented by Javascript:
浏览器端的导航可以通过Javascript实现：
<button onclick="location.href='<?php echo base_url();?>register/index'">Register</button>

If you want to use the CI form helper you have use it like this:
如果你想使用 CI 表单助手，你可以像这样使用它：
echo form_button('name','content');
// Would produce
// <button name="name" type="button">Content</button>
Or you can pass an associative array containing any data you wish your form to contain:
或者您可以传递一个关联数组，其中包含您希望表单包含的任何数据：
$data = array(
'name' => 'button',
'id' => 'button',
'value' => 'true',
'type' => 'reset',
'content' => 'Reset'
);
echo form_button($data);
// Would produce:
// <button name="button" id="button" value="true" type="reset">Reset</button>
If you would like your form to contain some additional data, like JavaScript, you can pass it as a string in the third parameter:
如果你想让你的表单包含一些额外的数据，比如 JavaScript，你可以在第三个参数中将它作为字符串传递：
$js = 'onClick="some_function()"';
echo form_button('mybutton', 'Click Me', $js);
And make sure that the helper is loaded:
并确保加载了帮助程序：
$this->load->helper('form');

You could write a common javascript function for your project if you need and can call it like below :
如果需要，您可以为您的项目编写一个通用的 javascript 函数，并且可以像下面这样调用它：
<button onClick="return redirect('<?php echo base_url();?>register/index');">Register</button>
and javascript function is as below:
和javascript函数如下：
<script>
function redirect(url){
window.location.href = url;
return false;
}
</script>
OR you could simply do the following
或者您可以简单地执行以下操作
<button onClick="window.location.href = '<?php echo base_url();?>register/index';return false;">Register</button>
Please remember to return false so that the default event of button click is ignored.
请记住返回 false 以便忽略按钮单击的默认事件。
