I’m using a condition and a switch to determine some values for some variables, but I’m not getting the expected results.
When the link <a href="index.php?post=myFile"></a> is clicked, I hope to run the first case on the switch, but the desired variables are not overwritten.
This is my code that is in my file called index.php.
$titulo = '';
$keywords = '';
$descricao = '';
$post = empty($_GET['post']) ? '' : $_GET['post'];
$pagina = empty($_GET['p']) ? '' : $_GET['p'];
if ($post != '' || ($post == '' && $pagina != '')) {
switch ($pagina):
case 'myFile':
$titulo = 'esta variável não muda o valor para esse arquivo';
$keywords = 'esta variável não muda o valor para esse arquivo';
$descricao = 'esta variável não muda o valor para esse arquivo';
break;
case 'home':
$titulo = 'Página Inicial';
break;
case 'ultimasnoticias':
$titulo = 'Ultimas Noticias';
break;
case 'contato':
$titulo = 'Contato';
break;
case 'privacidade':
$titulo = 'Privacidade';
break;
default:
$titulo = 'Home';
$pagina = 'home';
endswitch;
} else {
$titulo = 'Post';
}
<html>
<head>
<title><?php echo $titulo; ?></title>
<meta name="keywords" content="<?php echo $keywords; ?>">
<meta name="description" content="<?php echo $descricao; ?>">
</head>
<body>
<?php
if (empty($post)) {
require_once 'page_' . $pagina . '.php';
} else {
require_once 'posts/' . $post . '.php';
}
?>
<footer>Rodapé</footer>
</body>
</html>
My current results are:
$_GET["post"] = "myFile";
$_GET["p"] = NULL;
$titulo = "Home";
$keywords = "";
$descricao = "";
$pagina = "home";
My desired results are:
$_GET["post"] = "myFile";
$titulo = 'esta variável não muda o valor para esse arquivo';
$keywords = 'esta variável não muda o valor para esse arquivo';
$descricao = 'esta variável não muda o valor para esse arquivo';
$pagina = "home";
Why can’t I update the value of variables using the first instruction of case? In short, the values of mine case do not change only to files that are in a subdirectory
This is the code I use for my other links, which are in my main directory:
<nav>
<ul>
<li><a href="?p=home">Início</a></li>
<li><a href="?p=ultimasnoticias">Últimas Notícias</a>
<li><a href="?p=contato">Contato</a></li>
</ul>
</nav>
Note: I’m not sure if the image below will help in something, but through the doubts I put:
It is working yes: https://ideone.com/6WiYsS

@Maniero I’m doing something wrong and I couldn’t figure out what it is. Look, when I change the link from
<a href="index.php?post=myFile"></a>for?p=myFileyes thecasechanges the value of the variables. But it does not open the file inside thebodytag, being that it is in a sub-directory.– Sabrina marçã
So the question is about something else that is not described in the question? And we have no way of knowing what happens with the information posted?
– Maniero
@Maniero No, that’s exactly what I said in the question, the values of the
caseare only changed to the main directory files.– Sabrina marçã
And I just showed that in the way you presented it is not true. It is only if there is something missing or misspelled.

@Maniero I tried to run my script on the ideone site as you had done. But a lot of error appeared. https://ideone.com/Mk9MnO If the
caseis really working, so what I’m doing wrong, or how I find out?– Sabrina marçã
@Maniero I saw that on your link to the ideone you put these two lines
$_GET["post"] = "myFile";and$_GET["p"] = "myFile";, I put these lines in my script, and actuallycaseis working. Then maybe the problem is the querystring I’m using?index.php?post=myFile– Sabrina marçã
That’s what I said, there’s no way to know because the question doesn’t have enough information.
