Help with PHP and htacess Friendly URL

Question

I am new to PHP programming, I created a dynamic website using the following code:

   <nav>
        <ul class="navbar-nav">
            <li class="nav-item">
                <a class="nav-link" href="?pag=home">Home</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="?pag=contato">Contato</a>
            </li>
        </ul>
    </nav>

    <?php
    $paginas = @$_GET['pag'];
    switch ($paginas) {
        default :
            include 'home.php';
            break;

        case 'home':
            include 'home.php';
            break;

        case 'contato':
            include 'contato.php';
            break;
    }
    ?>

    <footer>

    </footer>

The navigation bar and footer are fixed, with the PHP "switches" replacing the central content.

To request the exchange of content use the following link:

        <li class="nav-item">
            <a class="nav-link" href="?pag=contato">Contato</a>
        </li>

My URL looks like this: http://www.meusite.com.br/? pag=cotato. But I wish she’d stay that way: http://www.meusite.com.br/contato.

However, I’ve tried everything I know about PHP to find a solution, but I can’t fix it, please help me.

Answer 1

You can take the URI $_SERVER['REQUEST_URI'];

And work on it to suit you.

Make a explode by / check which will be the Dice in which the domain ends and the next vc know it will be the controller and where will direct.

Answer 2

I managed to solve!

In my file .htaccess I wrote the following:

RewriteEngine on
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)$ index.php?pag=$1

Daí criei um pequeno PHP pra receber o valor da variável 'pag':

$getUrl = strip_tags(trim(filter_input(INPUT_GET,'pag',FILTER_DEFAULT))); // Filtra o que é digitado na url
$setUrl = (empty($getUrl) ? 'home' : $getUrl);  //Define o valor padrão para a variável
$Url = explode('/', $setUrl); // Cria um array com o que vai sendo inserido na URL

Answer 3

I’m adding a new answer with code to be tested

<?php
        $arrUri = explode("/", $_SERVER['REQUEST_URI']);
        switch ($arrUri[1]) {
            case 'home':
                include 'home.php';
                break;
            case 'contato':
                include 'contato.php';
                break;
            default :
                include 'home.php';
            break;
        }
?>

and tries to access with the friendly url ("meusite.com.br/contact.")

Assuming you are using Apache2 with the mod_rewrite enabled on your PHP server, you must create a file .htaccess at the root of your site with the following code:

RewriteEngine on
RewriteRule ^/(.*)/$ /?pag=$1

When the user tries to access for example http://meusite.com.br/faleconosco/, Apache will take anything that is placed between the two bars /(.*)/, in the 'faleconosco' case, and rewrite to the current format: http://meusite.com.br/? pag=faleconosco

Since you must have several other files on your site, the above code can make other Urls confusing, such as the header and footer of your site that you mentioned in the comments. To avoid this, you can redirect each of the pages specifically to your . htaccess as follows:

RewriteEngine on
RewriteRule ^/home/?$ /?pag=home
RewriteRule ^/contato/?$ /?pag=contato
RewriteRule ^/faleconosco/?$ /?pag=faleconosco
