How to access a file via htaccess? - php

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?

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:
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
Session can be spoofed too (read more here)

Why dont you just set the path for the domain on the "View" folder, so noone can access you controllers etc. ?
I think this should also be more simple than playing around with .htaccess !
This is the way most PHP Frameworks do it..
And if you need to access the functions of check.php you can make a "ajax.php" that checks if the request is ok, and then uses "check.php" to catch the result!

htaccess and POST variable issues with Codeigniter

So I am doing a bit of research on this topic, and you would think there would be an answer but there isn't, or maybe I am looking in the wrong area.
Problem
When submitting a form my post variables are empty. I am passing them through properly, the form goes where it needs to go to, and the variables and form data appear properly and with values, in the headers. I have the form helper autoloaded in the config, so everything is how it should be.
my form opener looks like this:
<form action='/Forms/form_processor/' method='post' id='testForm'>
In my Forms controller looks like this:
define('BASEPATH') OR exit('No direct script access allowed');
class Forms extends CI_Controller{
public function form_processor(){
// get variables
$name = $this->input->post('name');
// ... do stuff with variable data
}
}
I would also note that with the use of the htaccess file my config variables are:
$config['base_url'] = 'http://example.com/';
$config['index_page'] = ''; // this is to keep index.php out of the URL
Possible Cause
When using codeigniter and sitting at the home page, you get this URL:
http://example.com
That is fine, until you go to the next page, you get this URL:
http://example.com/index.php/page
It looks ugly, so for aesthetic purposes and to keep uniformity I created an htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /example.com/
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 http://example.com/
</IfModule>
and then by having this htaccess file at the base directory I get the URL to look like this:
http://example.com/page
Temp Fix and Questions Needing Answers
It was pointed out to me that because my $config['index_page'] variable is null that this is where the problems are stemming from. So I added the index.php to the beginning of my url in the form's action and it goes through.
Shouldn't the htaccess re-write handle this issue, and send it to where it is supposed to go where I have the index.php in the form's action URL or not?
Secondly, how would this affect the post variables? Because when I submit the form it still gets to where it needs to go to, it just shows null for all the variables, even though they are properly sent through the headers. This is where I am most confused.
If you need more information please let me know, but we are just trying to figure out why this is happening over here, it's kind of awkward. Thank you in advance!
Your question seems complicated. I think there might be an issue with installation steps. Remove index.php from config, set base url (also in application/config.php), set the encryption key(also there).
Check what are the session settings - did you change something there.
Also simplify htaccess (put it where is your index.php)
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
Is this local or server issue?
And last - try to use form helper, does it change something, whats inside console? Show more of your controller. You can check post inside one function
class Forms extends CI_Controller
{
function __construct()
{
parent::__construct();
}
function form_processor()
{
//check if $_POST
if ($this->input->post()) {
$name=$this->input->post('name');
//process and redirect
}
$this->load->view('forms/my_form');
}
}
Also if you use xss_filtering or csrf_protection(check that in config.php) you should definitely use form helper.
/forms/form_processor/' method='post' id='testForm'>
Use base URL in form action.
If not work so use index.php after base URL.

Implementing friendly links into custom CMS [duplicate]

Normally, the practice or very old way of displaying some profile page is like this:
www.domain.com/profile.php?u=12345
where u=12345 is the user id.
In recent years, I found some website with very nice urls like:
www.domain.com/profile/12345
How do I do this in PHP?
Just as a wild guess, is it something to do with the .htaccess file? Can you give me more tips or some sample code on how to write the .htaccess file?
According to this article, you want a mod_rewrite (placed in an .htaccess file) rule that looks something like this:
RewriteEngine on
RewriteRule ^/news/([0-9]+)\.html /news.php?news_id=$1
And this maps requests from
/news.php?news_id=63
to
/news/63.html
Another possibility is doing it with forcetype, which forces anything down a particular path to use php to eval the content. So, in your .htaccess file, put the following:
<Files news>
ForceType application/x-httpd-php
</Files>
And then the index.php can take action based on the $_SERVER['PATH_INFO'] variable:
<?php
echo $_SERVER['PATH_INFO'];
// outputs '/63.html'
?>
I recently used the following in an application that is working well for my needs.
.htaccess
<IfModule mod_rewrite.c>
# enable rewrite engine
RewriteEngine On
# if requested url does not exist pass it as path info to index.php
RewriteRule ^$ index.php?/ [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php?/$1 [QSA,L]
</IfModule>
index.php
foreach (explode ("/", $_SERVER['REQUEST_URI']) as $part)
{
// Figure out what you want to do with the URL parts.
}
I try to explain this problem step by step in following example.

I try to ask you like this :
i want to open page like facebook profile www.facebook.com/kaila.piyush
it get id from url and parse it to profile.php file and return featch data from database and show user to his profile
normally when we develope any website its link look like
www.website.com/profile.php?id=username
example.com/weblog/index.php?y=2000&m=11&d=23&id=5678
now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink
http://example.com/profile/userid (get a profile by the ID)
http://example.com/profile/username (get a profile by the username)
http://example.com/myprofile (get the profile of the currently logged-in user)
1) .htaccess
Create a .htaccess file in the root folder or update the existing one :
Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
# Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php
What does that do ?
If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.
2) index.php
Now, we want to know what action to trigger, so we need to read the URL :
In index.php :
// index.php
// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);
for ($i= 0; $i < sizeof($scriptName); $i++)
{
if ($requestURI[$i] == $scriptName[$i])
{
unset($requestURI[$i]);
}
}
$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :
$command = array(
[0] => 'profile',
[1] => 19837,
[2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :
// index.php
require_once("profile.php"); // We need this file
switch($command[0])
{
case ‘profile’ :
// We run the profile function from the profile.php file.
profile($command([1]);
break;
case ‘myprofile’ :
// We run the myProfile function from the profile.php file.
myProfile();
break;
default:
// Wrong page ! You could also redirect to your custom 404 page.
echo "404 Error : wrong page.";
break;
}
2) profile.php
Now in the profile.php file, we should have something like this :
// profile.php
function profile($chars)
{
// We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)
if (is_int($chars)) {
$id = $chars;
// Do the SQL to get the $user from his ID
// ........
} else {
$username = mysqli_real_escape_string($char);
// Do the SQL to get the $user from his username
// ...........
}
// Render your view with the $user variable
// .........
}
function myProfile()
{
// Get the currently logged-in user ID from the session :
$id = ....
// Run the above function :
profile($id);
}
Simple way to do this. Try this code. Put code in your htaccess file:
Options +FollowSymLinks
RewriteEngine on
RewriteRule profile/(.*)/ profile.php?u=$1
RewriteRule profile/(.*) profile.php?u=$1
It will create this type pretty URL:
http://www.domain.com/profile/12345/
For more htaccess Pretty URL:http://www.webconfs.com/url-rewriting-tool.php
It's actually not PHP, it's apache using mod_rewrite. What happens is the person requests the link, www.example.com/profile/12345 and then apache chops it up using a rewrite rule making it look like this, www.example.com/profile.php?u=12345, to the server. You can find more here: Rewrite Guide
ModRewrite is not the only answer. You could also use Options +MultiViews in .htaccess and then check $_SERVER REQUEST_URI to find everything that is in URL.
There are lots of different ways to do this. One way is to use the RewriteRule techniques mentioned earlier to mask query string values.
One of the ways I really like is if you use the front controller pattern, you can also use urls like http://yoursite.com/index.php/path/to/your/page/here and parse the value of $_SERVER['REQUEST_URI'].
You can easily extract the /path/to/your/page/here bit with the following bit of code:
$route = substr($_SERVER['REQUEST_URI'], strlen($_SERVER['SCRIPT_NAME']));
From there, you can parse it however you please, but for pete's sake make sure you sanitise it ;)
It looks like you are talking about a RESTful webservice.

The .htaccess file does rewrite all URIs to point to one controller, but that is more detailed then you want to get at this point. You may want to look at Recess

several conditions in apache mod rewrite to make custom URLs

In my domain example.com , I want to put all page files in a directory at root for example named file. So for example I put about.php the file directory and want to let users to access this page with this URL : example.com/about
or for example put user directory in the file directory and put login.php in it , and want to let users to access it with : example.com/user/login
In fact I want to remove .php and the file from the URLs.
AND
If those files don't exist , it should load a default file like index.php at root. for example the URL example.com/blabla should be mapped to the index.php
In fact , I want to make two conditions in mod rewrite with the mentioned priority.
notice : of course I should be able to use variables like $_GET at files like about.php
UPDATE : in summary , it should work with this logic :
if the URI isn't a file or directory{
if file/URI.php is a file
load file/URI.php
else
load index.php
}
some body gave an answer to use ErrorDocument 404 index.php , but it's a really bad idea (and now has deleted his answer !)
Thanks for your help...
A conditional rewrite (if the pages exist) sounds like a bad and complicated idea, if it even is possible.
I would rewrite everything to /index.php and control everything from there:
If the components of the url lead to an existing page, use / include that content;
If no valid page is found, present your original index content.
Example redirect rules for your situation:
RewriteEngine on
RewriteBase /
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^.*$ /index.php?id=$1 [QSA,L]
Will include the requested path in id and append the variables from the original query string (the QSA flag).
More specific for your /user/login example would be:
RewriteRule ^([\w-]+)/([\w-]+)$ /index.php?path=$1&file=$2 [QSA,L]
[\w-+] : any word character (including _) and the -

How to stop direct execution of a php page using htaccess rules?

In my .htaccess file I have defined the following rule to make my register page URL as http://example.com/register/
RewriteRule register/ /register.php
The above rule is perfectly fine but I can access my register page from http://example.com/register/ as well as from http://example.com/register.php.
I don't want that user will be able to access the URL from http://example.com/register.php URL, is there any RULE which I can define in .htaccess to stop execution of register.php URL or simply redirect any direct register.php request to /register/
If you are doing this to avoid getting multiple links to the same content, you can simply don't use "register.php" anywhere on your page. I think no search engine will "guess" for a certain file type and if there are no security concerns you are on the safe side, because in my opinion no user will link to this file either. However if you want to be certain just reroute all your functionality through an index.php via one line in your .htaccess which should be placed inside your www-root directory:
RewriteEngine on
RewriteRule ^(.*?)$ index.php?file=$1
In your index.php you can then simply choose which function/file to invoke by breaking down and checking the $_GET["file"] parameter. To make 100% certain no one can access your register.php file directly just move it (and all your others) to a separate directory and include a .htaccess file with the following line:
DENY from all
There are a couple of other options to prevent direct access. Just define() a variable somewhere in your index.php and at the top of your register.php just put
defined('access') or die('Intruder alert!');
at the top. Another way could be to be honest and simply tell search engines that your content has been moved and that they no longer should use the old link:
header("Status: 301"); /* Content moved permanently */
header("Location: http://yourserver/Register/");
exit;
Update
Just one more thing that crossed my mind, you can also check $_SERVER["REQUEST_URI"], whether the user attached any ".php" and act accordingly by either denying access completely or just redirecting to the new location.
It is true that you cannot use location directive, but you can actually paste .htaccess file into any directory.
Just if you put this into it, say:
Options -Indexes
order allow,deny
deny from all
you can copy paste this file into any (root) directory you want to protect from external execution.
To check the initial requested URL path, you need to use the request line. So try this rule:
RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php[/?\s]
RewriteRule (.+)\.php$ /$1 [L,R=301]
And then again your rule (in a slightly modified way):
RewriteRule ^register/$ register.php
If you want to completely block /register.php by using mod_rewrite, use a variant of SleepyCod's answer:
RewriteCond %{REQUEST_FILENAME} register\.php [NC]
RewriteCond %{IS_SUBREQ} false
RewriteRule .* - [F,L]
Explanation:
[NC]: Makes the condition case-insensitive, just in case you're on a windows box.
Condition 1: The requested filename is 'register.php', and
Condition 2: The request is no subrequest (this is important, since every new round through RewriteRules actually creates subrequests).
Rule: essentially do nothing
Flags: [F]: Send an 403 Forbidden header, [L]: This is the last rule to apply, skip all following rewrite rules
Rewriting correctly is an art by itself. I suggest you carefully read http://httpd.apache.org/docs/2.2/rewrite/.
Cheers,
Try this.
RewriteCond %{REQUEST_FILENAME} ^register\.php$ [NC]
RewriteRule ^/register register.php
Or this
Redirect register.php /register
Ignoring the user-experience part, you can implement the new rel=canonical link to sort out the search engines.
Although, for this case you should probably just use a 301 redirect from /register.php to /register/
In register.php
if ( stristr( $_SERVER['REQUEST_URI'], '.php' ) )
{
header ('HTTP/1.1 301 Moved Permanently');
header ('Location: /register');
}
