php - Code Igniter: Form's action cannot direct to the right path -

I am working on Code Igniter Project.

I have a php file in the View folder C: \ xampp \ htdocs \ mspn \ application \ views

The form has been written as: / P>

  & lt; Form action = "& lt;? Php echo base_url (). 'Home sign up / main';? & Gt; method =" post "& gt;   
 In the browser, the file is located in  localhost / mspn / index.php / signup / main   
 config.php I have:  
  $ config ['base_url'] = 'localhost / mspn /'; $ Config ['index_page'] = ''; $ Config ['uri_protocol'] = 'auto';   
 Form 'action' means in  homeSignUp.php  in the  Controller  folder that has a  main .  
 But when I tried to run it, the  submit  button was directed to  localhost / mspn / homeSignUp / main . And he said: The object was not found!  
 I am trying to change the URL to the  action  attribute, even then it gives me an error. What am i missing Thank you.   
 
 
 First of all,  index_page  config to:   $ config ['index_page'] = 'index.php';   
 then like  site_url () :  
  & lt; Form action = "& lt;? Php echo site_url ('homeSignUp') / main ');? & Gt; method =" post "& gt;  Note:  It looks like you're using a specific  route , then you  signup / main  homeSignUp / main  Code instead  
 Because the site url will include both  base_url  and  index_url  if any. You do not need to mention the  index.php  separator.
