pretty urls from database

Closed 5 years ago.
I just started learning php and i created a simple php website which contains posts, users. and i made posts links looks like : http://localhost/?post=3
my question is there any way to make the url looks differents like http://localhost/post/252155 without creating php pages for it.
Here is my code snippet
$results = mysqli_query($conn, "SELECT * FROM projects");
$project = array();
if (mysqli_num_rows($results) > 0) {
while($row = mysqli_fetch_assoc($results)){
$project[] = $row;
}
}
$projects = 0;
$maxprojects = 14;
while ($projects < $maxprojects) {
$projectId = $project[$projects]["project_id"];
$projectURL = "../basic/?project=".$projectId ;
$projectTitle = $project[$projects]["project_title"];
$projectThumb = $project[$projects]["project_thumbnail"];
$projectPrice = $project[$projects]["project_price"];
echo "
<li class='gig'>
<div class='gig-content'>
<span class='thumbnail'>
<a href='$projectURL'><img src='".$projectThumb."'></a>
</span><!-- Gig Thumbnail -->
<span class='title'>
<h2><a href='$projectURL'>".$projectTitle."</a></h2>
</span><!-- Gig Title -->
<div class='meta'>
<span class='price'>
<h1>".$projectPrice."$</h1>
<h4>Startin at</h4>
</span><!-- price -->
</div>
</div>
</li><!-- Gig -->
";
++$projects;
}
thanks in advance!

To accomplish this, you need to first create a text document called ".htaccess" to contain your rules. It must be named exactly that (not ".htaccess.txt" or "rules.htaccess"). There may already be a .htaccess file there, in which case you should edit that rather than overwriting it.
RewriteEngine On
RewriteRule ^post/([0-9]+)/?$ ?post=$1 [NC,L]
NOTE: Only If Application runs on Apache

A common approach is for you to have the web server route all URL requests to any arbitrary (so long as an actual resource–aka file–does not exist at that location). With the Apache web server, you can use create a .htaccess to route all URLs for which no file or directory exists, to your index.php file. For example, at the root of your publicly facing directory, its .htaccess could contain
<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 will route all URLs that do not exist as a file or directory to index.php in the root directory for the website. (This is the way that WordPress does it).
Then, within your index.php, you can parse the URL and serve up whatever content you wish base on the URL (or not). You can create your own routing system, within your PHP code, to direct content generation to whichever PHP page you prefer.
<?php
print_r($_SERVER['REQUEST_URI']);
For example, https://yourdomain.com/post/13452345 would output, /post/13452345.
%_SERVER['QUERY_STRING'], parse_url() and might also be useful. And installation/configuration dependent values might also be available: $_SERVER['SCRIPT_URI'] and $_SERVER['SCRIPT_URL']
More information can be found at the PHP reference site Predefined Variables, $_SERVER
You can parse the URI as you wish:
$URI_COMPONENTS = explode( '/', $_SERVER['REQUEST_URI'] );
if ($(URI_COMPONENTS[0] == 'post') {
// get $(URI_COMPONENTS[1])
// output response based on post value
// Maybe something like put_post_content($(URI_COMPONENTS[1]));
}
else
{
http_response_code(404); // Not a "post" request, so invalie URL
}

PHP how to redirect the page to a different PHP file? [duplicate]

This question already has answers here:
How to create friendly URL in php?
(8 answers)
Closed 6 years ago.
I couldn't find much help while I was looking for my answer that's the reason for the question on here.
Basically I have this bit of code :
More Info</span>
now how is it possible to get what I am passing ?
Do I make a php file called manage.php ? if so what makes it so that it looks at manage.php ? and then get it through $_GET but how is it possible ?
I am not sure how to go about it so I would appreciate any of yours suggestions.
Thanks
Your problem can have two possible solutions:
By creating manage.php file and passing query string to it.
Your code for the link will like this:
More Info</span>
Now on manage.php page, you can access user_id like this:
<?php $user_id = $_GET["user_id"]; ?>
Using .htaccess, create .htaccess file and put the code below in it. .htaccess file must be placed in same dir where your index.php file is.
<IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L] </IfModule>
Now you can access your query strings on index.php file using $_SERVER['REQUEST_URI'] global variable.
More Info</span>
Your link to access page must look like above note the / after 10000 else user_id will get merge with 10000
Chatting session was performed for the question, view chat transcript here
You need a routing-engine to manage that type of url.
There are many framework that include routing. The most used is Symfony http://symfony.com/doc/current/routing.html
The general syntax would be as follows:
http://domain_name.com/script.php?parameter1=value&parameter2=value
In your case you would have the following assuming that your parameter is
user_id:
More Info</span>
In PHP you would use $_GET['user_id'] to fetch the passed value
$userID = $_GET['user_id'];
By including these lines in .htaccess
RewriteEngine On
RewriteRule ^manage\/([0-9]+)$ manage.php?user_id=$1
You could reach the same page with the following syntax:
http://domainname/manage/2313
If you mean to say that you need to route to a different php file manage.php and get the passed variable from the previous page then either you can modify the link to
"manage.php?val=10000".$user["user_id"]
and then use $_GET to get the passed variable
Or else you can keep the same url use .htaccess to route your request to manage.php?val=$1
or else in frameworks like codeigniter you have routes file where you can define your route.

Joomla-like url rewrite

I know that similar questions were already asked, but i could not find any information for my specific "problem".
What i want to do is the following in a very dynamic way, which means that a "SuperUser" should be able to define new routes in a admin interface:
If a user enters http://www.example.com/nice-url/
he should get redirected to http://www.example.com/category.php?id=123 without changing the url.
Now there are a few ways i can achieve this. Either i use .htaccess like this:
RewriteEngine on
RewriteRule ^nice-url category.php?id=123 [L]
This works, but is not very dynamic. I would need to let a php script append new rules at the bottom which is not something i would like to do.
Or this:
.htaccess
FallbackResource /process.php
process.php
$path = ltrim($_SERVER['REQUEST_URI'], '/');
$elements = explode('/', $path);
if(count($elements) == 0) {
header("Location: http://www.example.com");
exit;
}
$sql = sprintf("SELECT Target FROM urlrewrites WHERE Source = '%s' LIMIT 1", array_shift($elements));
$result = execQuery($sql);
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);
$target = $row['Target'];
header("Location: ".$target);
exit;
This also works, but sadly the url in the address bar gets changed. Is there a way in the middle of both? Having the flexibilty of PHP and the "silentness" of RewriteEngine? How do great CMS like joomla do it? Do they generate a htaccess file for each new page you create?
Thanks!
You can have this code in root .htaccess:
RewriteEngine on
# If the request is not for a valid directory
RewriteCond %{REQUEST_FILENAME} !-d
# If the request is not for a valid file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ category.php?uri=$1 [L,QSA]
PS: Note this will route /nice-url to /category.php?uri=nice-url. Then inside category.php you can dip into your database and translate $_GET['uri'] to id.
It would be more dynamic if you use regular expressions. That's how it works in CMS systems like Joomla. Good idea is to install Joomla with 'nice' URLs on and look over .htacces file to get to know how does it work.

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.
http://en.wikipedia.org/wiki/Representational_State_Transfer
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
It's a RESTful framework all in PHP

Creating dynamic URLs in htaccess

I'm trying to write an .htaccess file that will make my URLs more attractive to search engines. I know basically how to do this, but I'm wondering how I could do this dynamically.
My URL generally looks like:
view.php?mode=prod&id=1234
What I'd like to do is take the id from the url, do a database query, then put the title returned from the DB into the url. something like:
/products/This-is-the-product-title
I know that some people have accomplished this with phpbb forum URLs and topics, and i've tried to track the code down to where it replaces the actual URL with the new title string URL, but no luck.
I know I can rewrite the URL with just the id like:
RewriteRule ^view\.php?mode=prod&id=([0-9]+) /products/$1/
Is there a way in PHP to overwrite the URL displayed?
At the moment you're wondering how to convert your ugly URL (e.g. /view.php?mode=prod&id=1234) into a pretty URL (e.g. /products/product-title). Start looking at this the other way around.
What you want is someone typing /products/product-title to actually take them to the page that can be accessed by /view.php?mode=prod&id=1234.
i.e. your rule could be as follows:
RewriteRule ^products/([A-Za-z0-9-])/?$ /view.php?mode=prod&title=$1
Then in view.php do a lookup based on the title to find the id. Then carry on as normal.
One way to do it, would be just like most mvc frameworks. You can redirect all your pages to the same index.php file, and you use your script to determine which page to load.
.htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>
and your php file will have a script like this one:
// get the url
$uri = (isset($_SERVER['REQUEST_URI']))?$_SERVER['REQUEST_URI']: false;
$query = (isset($_SERVER['QUERY_STRING']))?$_SERVER['QUERY_STRING']: '';
$url = str_replace($query,'',$uri); // you can edit this part to do something with the query
$arr = explode('/',$url);
array_shift($arr);
// get the correct page to display
$controller =!empty($arr[0])?$arr[0]:'home'; // $arr[0] could be product/
$action = isset($arr[1]) && !empty($arr[1])?$arr[1]:'index'; // $arr[1] can be product-title
}
of course you will have to work this code to fashion your application
I hope this helps
One way would be to output a Location: header to force a redirect to the chosen URL.
