I created a 404.php page for a website. Also, there is the .htaccess file ( in the /root ) having the ErrorDocument 404 /404.php line.
The website is having a multi-language functionality, something like this:
sitename.com/it/article1
sitename.com/en/article1
and so on ... There are numerous articles.
The 404.php page appears when I'm trying to access something like sitename.com/adsdasaerera but it doesn't appear when I'm trying to access sitename.com/en/adsdasaerera, adsdasaerera not being, obviously, an existing article.
How can I achieve this?
Ideally you would have one error 404 document page. On that page you would first set a default locale of en, and then determine the users browser locale/language they are using, and proceed to the next step which is displaying the error page in that language.
Since we are talking PHP, here is an answer how to detect the locale in PHP.
Simplest way to detect client locale in PHP
From there, the next step is basically using the strings associated for that locale from an array or a file and displaying them.
On this page you could also have some links to other translations that could be viewed(hidden elements that show div on click), if the user doesn't wish to read the error in the language their browser is set to use.
Did you try giving it a full path?
ex ErrorDocument 404 /site/error/404.html
Have you tried put the line ErrorDocument 404 /404.php into the apache global config file, maybe in /etc/httpd/.
Or is there an exising .htaccess file under somesite.com/en/ folder?
how do you archieve the multi-language functionality? rewrite in apache or .htaccess? and what does your PHP code?
in addition to Branimir Đureks answer, you may analyze the $_SERVER['REQUEST_URI'] string i.e. using explode() and if the article dosn't exists in the choosen language, send header("HTTP/1.0 404 Not Found"); otherwise display the article.
If you are NOT using a CMS etc, so the Language Folders are really existing, you can use this:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(ie|en|de)/ /404.php/$1 [R=404,L]
Explanation
The three conditions check that the requested file or folder does not exist
The rule checks that the requested url starts with one of the three countries then a /, captureing the country code to Group 1
It redirects to /404.php?lang=$1, e.g. /404.php?lang=en with a 404 code
In that 404.php you just need to Use $_GET['lang'] to get the requested Langugage.
But you already said, that the multi-language functionality is archieved in .htaccess. It would be helpfull to know whats in that file.
Anyway: If all Requests get redirected to one page (e.g. index.php), somethere in that file the Content of the site gets included. That hapens either with an include or similar of a file or with a Query to the Database.
Thats the point there you need to expand your code. If that file isn't found or if there is no record in the Database, you need to include your 404 File.
Please use this code at the bottom of .htaccess. Replace Path with your path.
RewriteRule ^pagenotfound$ 404.html
ErrorDocument 404 path/pagenotfound
It doesn't redirect you to the 404.php file because you accessed the existing file. Look at this URL
sitename.com/en/adsdasaerera
"adsdasaerera" is probably only a parameter value that is rewrited by htaccess. It's not a file. I suppose you have a "en" folder and index.php in it. So when you enter url above, you access that index.php in "en" folder with parameter "adsdasaerera" and that's the reason why you don't get 404 error. You can solve it by adding little code that searches trough the database for "adsdasaerera" and if it doesn't exist, in your code manually redirect it to 404.php file.
The reason why you get 404.php on this url
sitename.com/adsdasaerera
is because you don't have file named "adsdasaerera".
Hope it will help you :)
It should be possible to define an ErrorDocument like this in htaccess file:
ErrorDocument 404 http://sitename.com/404.php
and then do a language specific redirect check for requests in 404.php file.

I have a domain which I want every attempted url after https://www.example.com/someFolder/ to not give an error but instead give a php page.
For example, I do not have a somefolder/abc.php file but going there will run a process.php file instead and display it there.
I have attempted to modify the 404 page as the process.php but that also modifies the example.com/ error page which I do not want.
It would be great if I do not need to modify/add a file at the root directory
PS. adding a .htaccess to the somefolder folder does work somewhat but then the url shows somefolder/404.php and not somefolder/abc.php
Modify your 404 page as you did putting php script there but check in php if the url that was requested was directory or not. Depending on that make an appropriate action
<?php
$url = $_SERVER[REQUEST_URI];
// check if requested url was ending with slash
$pattern = '#\/$#';
$result = preg_match($pattern, $url);
if ($result === 1) {
//request was to directory suffixed with slash
//do your php code for custom 404
die; //end the page generation
}
?>
request was not to directory ending with slash
put html of regular 404 page here or leave it blank
I have learned that I could turn somefolder into somefolder.php and use the $_SERVER['PATH_INFO'] to make all pages exist.
This is something that can only be done, in the general case, by using the .htaccess file, and redirecting every request like this...
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,NC,L]
After that, you can use $_SERVER, $_SESSION, and other global variables in index.php to decide how to handle a 404 error (i.e., you can implement here how to define what a 404 is, etc.).
For instance, $_SERVER['PATH_INFO'] will be able to tell you what URL was requested, and you can use a combination of file_exists() and other calls, to determine if you want to display a full 404, search results, a redirect, or simply to display the results of another script.
This works for example.com/somefolder/, example.com/some/other/folder/, and example.com/a/b/c/d/e/f/g/, etc..
I've had a real tough time trying to search for the exact htaccess code that will allow me to do the following:
Visiting: http://www.domain.com/wildcard
Should show: http://www.domain.com/
But the URL should still read: http://www.domain.com/wildcard
So basically a transparent redirection... seems fairly straight-forward, but surprisingly hard to search for. The PHP in index.php is already set up to parse the subdirectory and read it as a parameter, but unfortunately my client never supplied me with the .htaccess file. #developerproblems
Thanks!
You just need this ErrorDocument 404 line at top of your .htaccess:
ErrorDocument 404 /
This will show home page for any request that is not a file or directory and results in a 404.
We will suppose that you have to receive a url parameter called param so your rewrite rule should be:
RewriteEngine On
RewriteRule ^([^/]*)$ /?param=$1 [L]
By this way any http://www.domain.com/AnythingHere will render the contents of http://www.domain.com/?param=AnythingHere so the home page is rendered.
However, such solutions, they are not change the contents, they may leads to SEO problems for repeated contents, So the solution of anubhava is better for SEO according to your usage.
I'm trying to get a wordpress page to "run" another page based on the url. So if I have a main page like:
/extensions
That will run the regular extensions page. But if I have urls like:
/extensions/test
/extensions/test/again
/extensions/text/again/etc
They will all just run the extension (no "s") page:
/extension
The extension page will parse the url and do it's thing at that point. I tried setting up a redirect rule in the .htaccess file like so:
RewriteCond %{REQUEST_URI} ^/extensions/.*
RewriteRule . /extension [L]
But I can't seem to get it going. I'm assuming wordpress is always parsing via the index.php file, which is some how trumping my little rewrite possibly. Is there anyway to set this up on wordpress?
Found the answer here.
Note that this should go into the functions.php file and you will have to hit save in the permalinks settings EVERY time you make a change to the function to see the effects.
i was given 3 static pages e.g
proposal.test.com/seo
proposal.test.com/ppc
proposal.test.com/design
I checked those directories in the server and there's no dynamic about their indexes, all plain htm file.
the instruction given to me was, hide those url from anyone that doesn't match a random url from database..meaning e.g
if user typed proposal.test.com/seo ,it shouldn't display the page, if the user
typed something like e.g proposal.test.com/seo/a13sdfa and a13sdfa matched a key from a databased, that's the only time the proposal.test.com/seo page will be displayed
so how am I gonna do this in PHP ? because all 3 directories are made up of pure static pages..
i have done the creating of keys already, i just wanna know how to hide these pages by appending a given random key and checking if it does or don't exists in database.
Since the pages are never considered PHP, you can not block the access using PHP.
You can block access by configuring your web server, for example by using a .htaccess file.
If you blocked access the normal way, you can use PHP to allow access to the files on certain conditions..
You should use mod_rewrite (in case of Apache web-server) and setup a rewriting of /a13sdfa into something like ?key=a13sdfa. Also you should include some PHP code in all static files in order to check the key validity.
How about this: move the static files outside the public folder, so they cannot be accessed directly; redirect all requests to a php file (you can use rewrite engine with apache) which will look in the database for the accessed url/key and return the file_get_contents of the corresponding file.
Here's an example of how the .htaccess file could look like:
RewriteEngine on
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)$ /index.php
What this does is the following: if the requested file doesn't exist on the disk (as a file or a directory), it will redirect to /index.php. There you should have the logic to render what page you want.
If you don't know in which variable the server will put the slug, just do a print_r($_SERVER) from inside index.php to find it.
There are 2 ways you could solve this problem.
1) (my prefered) Use .htaccess to only display the page if it matches the regex givin in the .htaccess.
2) In PHP (your actual question) 'Get the slug from the URL, query it to the database and if you get a result display it. Otherwise, send a 404 header from php.
Assuming the following: You have an Apache webserver with mod_rewrite enabled (check php info if you arent sure). Your virtual host allows overriding (AllowOveride All).
.htacces
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+) index.php?check=$1 [QSA,L,t]
If the file or directory exsists on the server it will display the page. So it would display seo, design etc. Otherwise it redirects to index.php and gives its slug as a parameter named $check. With this variable, query to the database, check te result and redirect to the desired page.
ok assume i have php page
has this name name.php?get= and has get varible named get
ok
how i can make it appear like that name?get=
If you are using apache, mod_rewrite is one way to go. There is a whole bunch of mod_rewrite tricks here.
I'd seriously reconsider before using (or overusing) mod_rewrite.
In almost all of my projects I use a simple mod rewrite in the .htaccess:
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^.*$ ./
AddHandler php5-script .php
This tells the server to forward all pages to / (index.php) unless a file otherwise exists.
In the root directory I have a folder called "views" with all of the pages that I use. E.g. the file used for /home would actually be /views/home.php. However, in the index.php I have a script that parses the user's url, checks for the file, and includes that.
$page = substr($_SERVER['REQUEST_URI'], 1);
if(!$page) :
header("Location: /home");
if(file_exists("views/$page.php")) :
include "views/$page.php";
else :
include "views/$page.php";
endif;
This creates a variable called $page that stores the value of everything in the URL after the domain name. I use a substr() function on the Request URI to get rid of the trailing forward slash (/) on the URL.
If the variable is empty, for example if the user is simply at http://example.com or http://example.com/ then it forwards them to /home, where the script then checks for the home.php file inside of the views folder. If that file exists, it includes it, and displays it to the user.
Else, the script will simply include the 404 page telling the user that the file doesn't exist.
Hopefully this helps you, and if you need any further explanation I'd be happy to help!
I think you're wanting to re-write the URL client-side, which would include mod_rewrite.
In the route of your website, create a file called .htaccess and place the following code in it:
RewriteEngine on
RewriteRule ^name?get=(.*) /name.php?get=$1
Now when you type http://www.example.com/name?get=something, it will actually map to http://www.example.com/name.php?get=something transparently for you.
As far as i could understand your question, you can not strip the file extension because otherwise it will not run. In other words, you can not change:
name.php?get=
into
name?get=
But if you mean to create links with query string values that you can put them in hyperlinks in this way:
Click here !!
If you're looking to create links using a variable '$get', then you can create the link like this:
<a href="name.php?get=$get>Link</a>
Or if you want to get the value of the query string variable, you can use this:
$get = $_GET['get']
