I don't know if I'm doing wrong but let's say I have this.
formulario.php
<? session_start();
$_SESSION['promedio'] = $number;
echo '
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<meta content="text/html; charset=utf-8" http-equiv=Content-Type>
<body>
<form action="main3.php" method="post">
Número de Encuestas <input type="number" name="number">
<input type="submit" value="Enviar"/>
</form>
</body>
</html> ';
?>
Now, in main3.php
<?
session_start();
$number = $_POST['number'];
$_SESSION['promedio'] = $number;
function Calcular($edades, $estado_civil, $genero){
global $number;
foreach($edades as $edad){}
echo "El promedio de edad general es: ".((array_sum($edades))/$number)."<br>";
$x;
$y;
$z;
$w;
$v;
$u;
$t;
foreach ($genero as $i) {
foreach ($i as $j) {
if($j == "Hombres")
{
$u++;
}
if($j == "Mujeres")
{
$t++;
}
$count_values[$j]++;
}
}
echo "Cantidad de hombres: ".$u."<br>",
"Cantidad de mujeres: ".$t."<br>";
foreach ($estado_civil as $a) {
foreach ($a as $b) {
if($b == "Soltero")
{
$x++;;
}
if($b == "Casado")
{
$y++;
}
if($b == "Separado")
{
$z++;
}
if($b == "Libre")
{
$w++;
}
if($b == "Viudo")
{
$v++;
}
$count_values[$b]++;
}
}
echo "Cantidad de personas solteras: ".$x."<br>",
"Cantidad de personas casadas: ".$y."<br>",
"Cantidad de personas separadas: ".$z."<br>",
"Cantidad de personas en unión libre: ".$w."<br>",
"Cantidad de personas viudas: ".$v."<br>";
}
echo '<form type="submit" action="resultados.php" method="post">';
for ($i=0; $i < $number; $i++) {
echo '
<html>
<h2>Datos de la persona '.$i.'</h2>

}
echo '
<input type="submit">
</form>
</html> ';
?>
Last file resultados.php
<?
include ("main3.php");
echo Calcular($_POST['edades'], $_POST['estado_civil'], $_POST['genero']);
?>
So, as you can see, I call the $number variable into a function and this is where the problem is. It keeps saying I'm dividing by zero, which means $number isn't saving the value through $_SESSION when I call it in Average(). I've some things to get this to work, but no luck.
Any suggestion or help about what I'm missing would be appreciated.
