Question

I have a folder structure like

Controller
  |_check.php

View
  |_  .htaccess
  |_ index.php
  |_  Webroot
          |_ js
              |_common.js
.htaccess    

In .htaccess

<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteRule    ^$ View/    [L]
   RewriteRule    (.*) View/$1 [L]
</IfModule>

In View/.htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

The outer .htaccess file links to View folder and there View/.htaccess links to index.php.

There is button in index.php(view file) with ajax to check.php.

I have given common.js The corresponding ajax function url as

var url = 'check.php'; // OR '../Controller/check.php'

The problem is the ajax is not working properly with two urls.

Whether I need change the folder structure to correct it or do I need to alter any htaccess file for accessing the check.php?

Answer 1

It’s not about the folder structure but rather the htaccess rewrite rules that are wrong.

Your htaccess in the “root” redirects all requests to the View folder (which defaults to index.php, I assume)

I don’t understand what you’re trying to accomplish, if you explain I might be able to help you.

In your current setup, you can’t access any file besides View/index.php (even when passing GET argument url)

EDIT:

In that case, if you wish to View/index.php be the only file accessible and force people to pass through View/index.php file, you can use PHP session variable.

Something like this…

in the top of your view.php file:

   session_start();
   $_SESSION['viewCheck'] = true;
   //rest of view.php code

in your check.php code (or the file you’re trying to access via AJAX)

session_start();
if (isset($_SESSION['viewCheck']) && $_SESSION['viewCheck'] === true) {
    //Code of check.php
} else {
    //Error message or redirect to view.php, for instance

    //error message example
    header('HTTP/1.0 401 Unauthorized');

    //Redirect example
    header("Location: http://www.yourhost.com/View/index.php");
}

NOTE 1:
You should remove the rewrite rules of your htaccess files.

NOTE 2:
Keep in mind that this is not bullet proof (and can be spoofed) since:

1. If someone visits View/index.php then he can access check.php freely. This can be mitigated if the session is killed after the ajax request. You can accomplish that if the ajax request consists in 2 requests, for instance, one to get a session key which expires in 10 seconds for instance, and then use that key to obtain the results from check.php

2. Session can be spoofed too (read more here)
