CodeIgniter URI and Form Action

let's say that we are on

somesite.com/mail

this means that we are using a controller named "mail". This controller has the function:

 public function index(){ $this->load->view('header'); $this->load->view('mail/contact_form'); $this->load->view('footer'); }

This function loads when we enter the address bar only

 somesite.com/mail

and press enter (no additional arguments). And look at the first line of the form contact_form:

 <form role="form" method="post" action="sendmail">

And that is my problem. When I type the address with a backslash at the end, for example:

 mysite.com/mail/

and use my contact formula, everything works fine, and my Mail controller loads the sendmail function, and now the URL:

 mysite.com/mail/sendmail/

But when I forget about the backslash (mysite.com/mail), it searches for a controller named "sendmail", but I don't want that. Then my url:

 mysite.com/sendmail

but of course I don't have controllers named sendmail. My question is: how do I change the action of my formula or what should I do to make this work well? Is this the only answer you need to remember about the backslash or what?

As a simple example, to give you should use CI site_url()

site_url("controller/function") and it will take care of other url actions.

 <form role="form" method="post" action="<?php echo site_url('mail/sendmail');?>">

Go through url_helper

use base_url('mail/sendmail')

in the following way

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

Be sure to change to make lowercase, or it will not allow you to send special characters such as

 $config['charset'] = 'utf-8';

The first url call. Then give an action in the form of type action="<?php echo base_url();?>index.php/mail/sendmail"

then write the code in the controller function
