RewriteRule creating 500 Internal Server Error - php

I have the following in my .htaccess file:
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^directory/(.*)$ directory/index.php?id=$1
What I'm trying to achieve is this:
When the URL www.example.com/directory/10 is visited, the page www.example.com/directory/?id=10 is displayed on the browser without altering the appearance of the URL.
The above code creates a 500 Internal server error though.
Does anyone know where I'm going wrong?

Your code is guaranteed to generate 500 internal server error because it is causing infinite looping. Reason is that your matching URI pattern is: ^directory/(.*)$
Which matches your URLs before and after rewrites. And once it reaches max allowed internal rewrite limit Apache throws 500 internal server error and bails out.
Change your code to this:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^directory/(.*)$ directory/index.php?id=$1 [L,QSA,NC]
Above code has an extra RewriteCond %{REQUEST_FILENAME} !-f that will make sure to disallow subsequent execution of RewriteRule after first time since /directory/index.php will be a valid file.

I have got the same issue and found that "rewrite" module is not yet enabled in my case. So I need to enable it and then restart apache server:
Enable "rewrite" module: sudo a2enmod rewrite
Then restart apache server: sudo service apache2 restart
Hope this will help anyone.

You should try adding a forward slash to the front:
RewriteRule ^/directory/(.*)$ directory/index.php?id=$1
I've been caught out with that before.
Alternatively use the RewriteLog and RewriteLogLevel to debug, and look at the Apache error and access logs for further info:
RewriteLogLevel 3
RewriteLog ${APACHE_LOG_DIR}/rewrite.log
That will leave a log file in your apache log directory. In my case that is /var/log/apache

If you are using CodeIgniter and is in error problems 500. Follow the solution.
So to delete the segment "index.php" of URLs in CodeIgniter, you need to do 2 things. The first is to edit the /system/application/config/config.php file, changing the value of index_page policy to empty:
$config['index_page'] = '';
The second step is to create a file .htaccess
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
And that's it! From now on, the URLs of your site/system made with CodeIgniter will no longer have the thread (called "annoying" by some) "index.php".

Another day searching for a strange error on Apache.
Working on my Docker Apache 2.4.48 alpine container. But not in production.
Here is the difference (just a dot):
Not working on hosting provider
RewriteRule ^public/(.*)$ ./public/index.php?route=/$1 [L,QSA]
Working on hosting provider
RewriteRule ^public/(.*)$ /public/index.php?route=/$1 [L,QSA]

Just uncomment #LoadModule rewrite_module lib/httpd/modules/mod_rewrite.so
Because by default it was disabled/commented

There is "/?i=2" in my wordpress website index url

I recently grabbed a host and first there was an index2.html in my htdocs root which was default index, I didn't remove that until I install wordpress in that root. then wordpress automatically made a httaccess file with following codes which is normal:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
now I realize that sometimes there is /?i=1 or /?i=2 in my general url, for example, wordpresssite.com/?i=2
this is a problem because I'm using some ad-unit system and I gave my website url to the system but it seems that the ad system bots some time redirect to "wordpresswebsite.com/?i=2" url and it does not match with the url I entered before (wordpresswebsite.com) so it's not gonna work.
now I removed the index2.html but the problem is still there.
this ?i=1 or 2 is about PHP GET parameter but how this parameter will appear.
I found this on reddit with similar issue and the conclusion was:
Most likely there are some rules at vhost level.
---- yes it's from the host, they said they cannot disable it as it's protecting me from bots.
For those interested in removing the /?i=1 installed mostly by free host providers here's a tip.
Edit & upload the .htaccess file in root of website
RewriteCond %{QUERY_STRING} ^(.*)\?i=1$ [NC]
RewriteRule ^(.*)$ /$1?%1 [R=301, L]
If you're using Apache, you have to enable mod_rewrite first.
sudo a2enmod mod_rewrite
Then restart or reload your server for the new configuration to take place:
sudo service apache2 restart
(Try to find some fancy control panel option for this, if not having shell access)
?i=1 or 2 or 3 is to protect your website from bots. Try using cloudflare for your website or use the .htaccess code to remove ? paramaters. Note that using any code to remove ?i=1 will remove all ? parameters.

Codeigniter - getting 404 Not Found error

We have two hosting packages at godaddy. Our live website is working fine using following .htaccess file. Website is accessible without using index.php in url.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
We used same htaccess file and same code on other hosting that is also by godaddy. We just wanted to make production and development instances seperate. But on other hosting with same code and htaccess file, website shows 404 page not found error but website works fine with index.php in url.
We have same php version on both server. Just wants to know what could be the issue?
I also faced the similar problem when I move my 100% working code to dedicated Debian server. After 3 hours of research, i found out why htaccess file is not working.You need to allow overriding of htaccess in Apache Configuration.
Here are the steps.
Step 1:
Add this in htaccess file
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
</IfModule>
Step 2:
Remove index.php in codeigniter config
$config['index_page'] = '';
Step 3:
Allow overriding htaccess in Apache Configuration (Command)
sudo nano /etc/apache2/apache2.conf
and edit the file & change to
AllowOverride All
for www folder
Step 4:
Restart Apache (Command)
sudo /etc/init.d/apache2 restart
Before you make any changes in apache2.conf file make sure to make a backup copy of that file. If you are using Debian server you can avoid sudo command. I believe you know how to connect to your server using ssh client software like putty. Comment below if this method does not work for you.
Follow this
Create a new .htaccess file in your public_html/Project root
Paste the following code
RewriteEngine on
RewriteBase /
RewriteCond $1 !^(index\.php|resources|robots\.txt|static) [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/?$1 [L,QSA]
Optional
If you can ssh into the server using command ssh username#ip_address on a command line either Linux terminal or Putty
The username is the one given to you by GoDaddy or you can use root
The ip_address would be the Public IP to your host you can find it in your hosting panel
Run the command sudo a2dissite 000-default
The command disables the default apache config that handles request
Goodluck!
You can use this. This works for me in godaddy hosting.
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php?/$1
try this one.. it's works for me..
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]
I have faced the similar problem when I move on godaddy server.And It's work for me.
Add this code into your .htaccess file.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Rewrite all other URLs to index.php/URL
RewriteRule ^(.*)$ index.php?url=$1 [PT,L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 index.php
</IfModule>
In config file:
$config['base_url'] = 'domain.com';
$config['index.php'] = '';
And Set AllowOverride to All in your httpd.conf
set the correct permission on the /cache folder, rather than just making the folder writable you need to make it reclusively writable.
I hope it will work for you.
Try to lowercase all your controllers. This fix the problem for me.
in index.php you echo "test" and run .then you can check whether it is called or not.
in config file enable error log .
Make your /application/logs folder writable.
In /application/config/config.php set. $config['log_threshold'] = 4;
check the log /application/logs folder
I have limited knowledge in server networking but this should give you a few ideas.
First ,you must know what is .htacess file is. you can check it here link
.htaccess is a configuration file for use on web servers running the
Apache Web Server software. When a .htaccess file is placed in a
directory which is in turn 'loaded via the Apache Web Server', then
the .htaccess file is detected and executed by the Apache Web Server
software. These .htaccess files can be used to alter the configuration
of the Apache Web Server software to enable/disable additional
functionality and features that the Apache Web Server software has to
offer. These facilities include basic redirect functionality, for
instance if a 404 file not found error occurs, or for more advanced
functions such as content password protection or image hot link
prevention.
Basically .htaccess is giving you permission to edit the configuration of Apache Web Server. You will gain permission using .htacess if mod_rewrite is enabled in Apache. I will not write what that 4 basic line in .htaccess can do in codeigniter because you can find it in google. this link can give you some nice basic info.
Now the main issue is .htaccess is not working in your other hosting. This is possible because a few reason :
For some reason, mod_rewrite is disabled in your Apache Web Server. If your hosting is VPS or DS it's possible you are didn't configuring it yet. Someone already ask how to enable mod_rewrite, you can go to this link. If you are using Shared Hosting, ask your hosting to enable mod.rewrite in your host. You can check if mod.rewrite enabled or not in your hosting following this link. Or you can simply check with <?php phpinfo(); ?> and check in "Loaded Modules" for mod_rewrite exist or not. Example in this image.
You are not using Apache as Web Server. There are others Web Server as NGINX and lighttpd. You should ask your server administrator what Web Server are you use currently. I dont have any experience using NGINX and lighttpd so i cannot give you any help in that. But as far as i know .htaccess code is different in APACHE, NGINX, and lighttpd. You can try to convert .htaccess apache code to nginx code in here or here. For converting .htaccess to lighttpd unfortunately, i cannot find any online converter but there are official guide here and here
Well for the complete tips sake i will write this. It's possible you are not configuring codeigniter to not use index.php. In config file, empty configuration for index_page. and give Base_url your domain name. $config['base_url'] = "yourdomainname.com"; $config['index_page'] = '';
I hope this clear your confussion why your .htaccess didnt work.
As you mentioned here, on localhost your code is working fine but when you moved it over live server it causes 404 error. There might be few cases you need to check:
Step 1: Check mod_rewrite is enabled or not in your Apache configuration
Step 2: Remove index.php in codeigniter config as #geordy suggested
You can check it by
<?php
echo 'Test'; die;
?>
in your root index.php. It ensures your all requests should go through this files else Codeigniter framework would not work properly.

Error with .htaccess mod-rewrite

I get error 500 Internal Server Error when using the below lines in .htaccess file in the main directory of the website.
RewriteEngine on
RewriteRule ^ar/?$ index.php?lan=ar [L]
RewriteRule ^en/?$ index.php?lan=en [L]
My intention is load website.com/index.php?lan=en when entering website.com/en. What could be the issue here?
Have you check if the mod_rewrite is enabled on your apache server ?
If you are on Windows, check the httpd.conf file inside the apache/conf directory on your web server.
On linux like Debian / Ubuntu, check if there is the file rewrite.so in /etc/apache2/mod-enabled/ directory. Otherwise, add the module with the command a2enmod rewrite && service apache2 restart
I am also not seeing an issue here might be some other rule or conflicting htaccess, but you can do that easily by,
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([\w-]+)/?$ index.php?lan=$1 [QSA,L]

How do I redirect non-existant subdirectory in my index.php file, keeping the URL

I want to basically be able to goto, for example: www.example.com/my/folder/
where the subdirectories /my/folder/ don't exist, and have it redirect to index.php?path=/my/folder, while still keeping the original URL.
I hope this makes sense. I basically have no idea where to start with this. I'm guessing it's something with .htaccess, or http.conf or something, but I have no clue.
I basically want some direction on where to figure out how to do this, or some suggestions.
I always liked borrowing from the Wordpress .htaccess file myself
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
This little bit of code will rewrite anything that is not a file and send it to your index.php file. You can then parse $_SERVER['REQUEST_URI'] for anything you need from the URL itself.
It depends on what web server you're running. If you're running Apache, then yes, it's in the .htaccess file or the VirtualHost file. In addition, mod_rewrite will need to be enabled on your Apache server for this to work.
sudo a2enmod mod_rewrite
sudo service apache2 restart
Other web servers will have it in different locations and require different commands.

CodeIgniter 500 Internal Server Error

I downloaded a PHP script written using CodeIgniter. when I run it from the localhost, on going to the admin folder, it shows localhost again. Also when running from my web host, it shows a 500 Internal Server Error.
I run the site from http://localhost/myproj It works. Then when I try to go to the admin page which is at http://localhost/myproj/administrator, it gives a 500 Internal Server Error.
I read here that this might be due to a wrong code in the .htaccess file. This is my present .htaccess file
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ $1 [L,R=301]
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
# Without mod_rewrite, route 404's to the front controller
ErrorDocument 404 /index.php
Please help me. I know it might be a very small problem, but I'm unable to find the error.
The problem with 500 errors (with CodeIgniter), with different apache settings, it displays 500 error when there's an error with PHP configuration.
Here's how it can trigger 500 error with CodeIgniter:
Error in script (PHP misconfigurations, missing packages, etc...)
PHP "Fatal Errors"
Please check your apache error logs, there should be some interesting information in there.
Just in case somebody else stumbles across this problem, I inherited an older CodeIgniter project and had a lot of trouble getting it to install.
I wasted a ton of time trying to create a local installation of the site and tried everything. In the end, the solution was simple.
The problem is that older CodeIgniter versions (like 1.7 and below), don't work with PHP 5.3. The solution is to switch to PHP 5.2 or something older.
You're trying to remove index.php from your site URL's, correct?
Try setting your $config['uri_protocol'] to REQUEST_URI instead of AUTO.
Try this to your .htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule >
Make sure your root index.php file has the correct permission, its permission must be 0755 or 0644
remove comment in httpd.conf (apache configuration file):
LoadModule rewrite_module modules/mod_rewrite.so
Whenever I run CodeIgniter in a sub directory I set the RewriteBase to it. Try setting it as /myproj/ instead of /.
I know I am late, but this will help someone.
Check if rewrite engine is enabled.
If not, enable rewrite engine and restart server.
sudo a2enmod rewrite
sudo service apache2 restart
if The wampserver Version 2.5 then change apache configuration as
httpd.conf (apache configuration file):
From
#LoadModule rewrite_module modules/mod_rewrite.so**
To ,delete the #
LoadModule rewrite_module modules/mod_rewrite.so**
this working fine to me
Pretty late to the party but, i think the best approach to 500 internal server errors in CodeIgniter would be to enable the error log functionality in the Config.php file in the config folder and set a threshold value i.e. $config['log_threshold'] = 1,2,3,4 depending on the logs you want to view.
This probably isn't relevant any more to this thread, but hopefully helpful to somebody.
I've had 500 errors for the past hour as I had a controller return an array not supported by the php version ran on my (crappy) server. Seems trivial but had the hallmarks of a codeigniter error.
I had to use:
class emck_model extends CI_Model {
public function getTiles(){
return array(...);
}
}
Instead of
class emck_model extends CI_Model {
public function getTiles(){
return [...];
}
}
Cheers
This works fine for me
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule >
If your are using local server, this problem is faced in Wampserver when the essential modules are not enable.
You can Enable them with:
Left click on Wampsever icon
Go to APACHE -> APACHE MODULES
scroll down and find "rewrite_module" and "headers_module"
Then mark them check
It will restart automatically. Done.
