Friendly URL using HTACCESS

Resolution

Remove ? before m and use $1 variable:

RewriteRule ^film/([a-z0-9\-]+)/?$ index.php?p=filmes_v&m=$1 [NC]

The htaccess will look like this:

<IfModule mod_rewrite.c>
  RewriteEngine On

  RewriteRule ^film/?$ index.php?p=filmes [NC,L]
  RewriteRule ^film/([a-z0-9\-]+)/?$ index.php?p=filmes_v&m=$1 [NC]
</IfModule>

Note that within [] in regular expressions it is recommended to escape - , since they are used in the syntax of the expression, such as [a-z] , which indicates a to z . - @GreenGirls

Links and Scripts

Using friendly URL you can use absolute paths or just reference the files indicating a / at the beginning of the path:

<link href="http://meudominio.com/css/meucss.css">
<!-- ou -->
<link href="/css/meucss.css">

<a href="http://meudominio.com/contato">
<!-- ou -->
<a href="/contato">

<script src="http://meudominio.com/js/jquery.min.js"></script><!--ou--><scriptsrc="/js/jquery.min.js"></script>

Relative Paths

Caution: Relative Paths must be started with / indicating the root of the site, because if the current page has an address similar to http://meudominio.com/contato user clicking on a <a href="sobre">Sobre</a> link it will end at the http://meudominio.com/contato/sobre address.

A very interesting feature to use with relative paths is RewriteBase . For example imagine that you have a blog and it is structured more or less like this on the server:

/root
| - /www
|   | - /blog
|       | - /css
|       | - /js

And the URL to access this blog is http://meusite.com/blog/ so in all your code you will have to reference your scripts and links using the semi relative URL /blog/ .

<link href="/blog/css/estilos.css" rel="stylesheet" type="text/css">
<script src="/blog/js/scripts.js" type="text/javascript"></script>
<a href="/blog/sobre">Sobre</a>

But if Blog is set to htaccess to RewriteBase , you will no longer need blog in the URL:

RewriteBase /blog/

And your URLs can stay:

<link href="/css/estilos.css" rel="stylesheet" type="text/css">
<script src="/js/scripts.js" type="text/javascript"></script>
<a href="/sobre">Sobre</a>

And so if at some point you resolve to change the address /blog/ to http://meusite.com/blog/ you only need to change http://blog.meusite.com to RewriteBase or remove it:

RewriteBase /

So you do not need to change all the links by removing such / from the URLs.)

You can also have this feature via the tag /blog . But I prefer not to base .

Other means

A very interesting way to make friendly URLs is what I call Dynamic Friendly URLs , the implementation would look like this:

<IfModule mod_rewrite.c>
  RewriteEngine On

  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f

  RewriteRule ^(.*)$ index.php?uri=$1
</IfModule>

In this way you can treat the URI in PHP to receive as many variables as you want, eg:

$tmp = !empty($_GET['uri']) ? $_GET['uri'] : 'home'; // Página padrão home

$uri = explode('/', $tmp);

$vars = Array();

if (count($uri) > 1){
    $key = 'page';
    foreach ($uri as $val) {
        if (is_null($key))
            $key = $val;
        else {
            $vars[$key] = $val;
            $key = NULL;
        }
    }
}

In the previous example, you can send the URL htaccess and you would have the following structure in the variable http://meudominio/catalogo/categoria/eletrodomestico/preco/100~500/voltagem/220 :

page        => catalogo
categoria   => eletrodomestico
preco       => 100~500
voltagem    => 220

So the first argument is always the page and the following are any parameters you want, in any order and should always be sent in double $vars . This form is very useful for making filters.

MVC model

Using this concept it is simple to apply an MVC model that would be:

controller/action/demais/parametros

As for example:

$tmp = !empty($_GET['uri']) ? $_GET['uri'] : 'home'; // Página padrão home

$uri = explode('/', $tmp);

$vars = Array(
    // Controller 'index' caso não tenha parâmetros na URI, caso tenha armaza e remove-o da URI
    'controller'   => (count($uri) > 0 ? array_shift($uri) : 'index'),
    // Action 'index' caso não tenha parâemtros na URI
    'action'       => (count($uri) > 0 ? array_shift($uri) : 'index'),
    // Demais parâmetros
    'params'       => Array()
);

$key = NULL;
if (count($uri) > 1){
    foreach ($uri as $val) {
        if (is_null($key))
            $key = $val;
        else {
            $vars['params'][$key] = $val;
            $key = NULL;
        }
    }
}

So by accessing the URL:

www.meudominio.com/sobre/empresa/page/3

We will have the following result:

$vars = Array(
    'controller' => 'sobre',
    'action'     => 'empresa',
    'params'     => Array(
        'page' => '3'
    )
);
