Un ejemplo de con sesion añadir productos a un carrito:
<?php
session_start();
$conexion=mysqli_connect('localhost', 'root', '', 'examen');
#accion
$id=$_GET["id"];
$sql="SELECT * from productos where id = '$id'";
$result=mysqli_query($conexion,$sql);
while($mostrar=mysqli_fetch_assoc($result)){
$_SESSION["carrito"][]=array(
"id"=>$mostrar["id"],
"categoria"=>$mostrar["categoria"],
"color"=>$mostrar["color"],
"marca"=>$mostrar["marca"],
"precio"=>$mostrar["precio"]
);
}
if(isset($_GET["categoria"])){
$categoria=$_GET["categoria"];
header("Location: muestraProductos.php?categoria=$categoria");
}
else{
header("Location: muestraProductos.php");
}
?>
Y aqui comprobamos que se han añadido al carrito
<?php
#Carrito
session_start();
if(isset($_SESSION["carrito"])){
?>
<table >
<tr>
<th>CategorÃa</th>
<th>Color</th>
<th>Marca</th>
<th>Precio</th>
</tr>
<?php
$total=0;
foreach($_SESSION["carrito"] as $indice => $valor){
echo "<tr>";
echo "<td>".$valor["categoria"]."</td>";
echo "<td>".$valor["color"]."</td>";
echo "<td>".$valor["marca"]."</td>";
echo "<td>".$valor["precio"]."â¬</td>";
echo "</tr>";
$total = $total+$valor["precio"];
}
echo $total."⬠";
echo "<a href='pagar.php'><button
type='button'>Pagar</button></a>";
}
else{
echo "<h1>El carrito está vacÃo</h1>";
}
?>
