Now the problem is the following, to add the item, I need only type what the item will be and select the category to which it will be added, I am now having difficulty inserting the item into the selected category, my code is so

<?php
include("conecta.php");

$item=$_POST['item'];
$categoria=$_POST['categoria'];

$sql="INSERT INTO itens (item, id_cat) VALUES (\"$item\", \"$categoria\")";

$conexao->query($sql);

$linhasAfetadas=$conexao->affected_rows;

if($linhasAfetadas > 0){
    header("location:gerenciar.php");
} else {
    echo "<strong>Houve um erro ao registrar os itens e categoria!</strong>";
    echo "<a href=gerenciar.php>Voltar para a página anterior</a>";
}

You did not connect to the Database, if you are using PDO, you should create a new connection:

$conexao = new PDO('mysql:host=servidor;dbname=bancodedados', 'usuario', 'senha')
