I have this PHP code working,

<?php
include "../conexao.php";
$codigo = $_POST['codigo'];
$nome_marca = $_POST['nome_marca'];
$query = mysql_query("SELECT * FROM marca order by nome_marca")or die(mysql_error());
while($res = mysql_fetch_array($query)){
?>
<ul>
    <li><a href="prod_index_marca.php?codmarca=<?php echo $res['codigo'];?>"><?php echo $res['nome_marca'];?></a></li>
<?php
}
?>
</ul>

and which directs the href to the page according to the code referring to the selected brand.

And the landing page is with this PHP code

<?php
include "../conexao.php";
$codmarca = $_GET['codmarca'];
$query = mysql_query("SELECT * FROM produto WHERE codmarca = '$codmarca'");
while($res = mysql_fetch_array($query)){

$codigo = $_POST['codigo'];
$img01 = $_POST['img01'];
$descricao = $_POST['descricao'];
$titulo = $_POST['titulo'];
$codcategoria = $_POST['codcategoria'];
$codmarca = $_POST['codmarca'];
$preco = $_POST['preco'];
$pagseguro = $_POST['pagseguro'];
$titulo = $_POST['titulo'];
?>

that receives the data via $_GET.

My question is whether you can adapt these codes to work with $_SESSION?

And if so, friends can guide me how to convert them, or even where I can get information on the subject.

Here is my thanks to all, for the attention to my doubt.

    remembering that Session is only between the same domain, and today it is not recommended to store a lot of data in Session

  • honestly, does it not... adapting code to get wrong is not a good practice!

I assume you already know how a session works.

So you’ll practically change your $_POST for $_SESSION (post in this case will not work, as it is only used in Formularios Ubmit)

Remember that to use Sesssions, you must initialize with the function session_start(); always when reading or writing a variable in the session. Give preference to always use the first line of the code, because if there is a text output (or PHP notice or Warning error) will cause error in the script

follow the official documentation of session_start I assume you already know how a session works.
