CodeIgniter's URI and form action
提问by hugerth
let's say we are on
假设我们在
somesite.com/mail
it means we are using controller named 'mail'. This controller has function:
这意味着我们正在使用名为“邮件”的控制器。该控制器具有以下功能：
public function index(){
$this->load->view('header');
$this->load->view('mail/contact_form');
$this->load->view('footer');
}
This function is loaded when we type in adress bar just
当我们在地址栏输入时加载这个函数
somesite.com/mail
and press enter (no additional arguments). And let's see first line of the contact_form view:
然后按回车（没有额外的参数）。让我们看看 contact_form 视图的第一行：
<form role="form" method="post" action="sendmail">
And that's my problem. When I type adress with backslash on the end like this:
这就是我的问题。当我像这样在末尾输入带有反斜杠的地址时：
mysite.com/mail/
and use my contact formula, everything works good and my Mail controller loads function sendmail and the URL is now:
并使用我的联系公式，一切正常，我的邮件控制器加载函数 sendmail 并且 URL 现在是：
mysite.com/mail/sendmail/
But when I forget about backslash (mysite.com/mail), it looks for controller named "sendmail" but I don't want it. My url is then:
但是当我忘记反斜杠 (mysite.com/mail) 时，它会查找名为“sendmail”的控制器，但我不想要它。我的网址是：
mysite.com/sendmail
but of course I don't have any controllers named sendmail. My question is - how to change action of my formula or what should I do to make this working good? Is the only answer to remember about backslash or what?
但当然我没有任何名为 sendmail 的控制器。我的问题是 - 如何改变我的公式的动作或者我应该怎么做才能使这个工作正常？关于反斜杠或什么，唯一要记住的答案是什么？

As simple example as to give you is to use CI's site_url()
给你的简单例子是使用 CI site_url()
site_url("controller/function")and it will take care of other url things
site_url("controller/function")它会处理其他 url 的事情
<form role="form" method="post" action="<?php echo site_url('mail/sendmail');?>">
Go through url_helper
回答by Kyslik
please use base_url('mail/sendmail')
请用 base_url('mail/sendmail')

如下
<form role="form" method="post" action="<?=base_url('mail/sendmail')?>">

Don't forget to change to make in lower case or it wont allow you to submit special characters like ó
不要忘记更改为小写，否则它不会允许您提交特殊字符，如 ó
$config['charset'] = 'utf-8';

First call url helper.
Then give action in form like action="<?php echo base_url();?>index.php/mail/sendmail"
首先调用 url helper。然后以类似的形式给出动作action="<?php echo base_url();?>index.php/mail/sendmail"
then write the code in controller function
然后在控制器函数中编写代码
