Recoger valores checkboxes

[grassofabian]

Primero tenes que definir la variable "area" como array:

<form action="pruebas.php" method="POST">
<input type='checkbox' name="area[]" value="area1" selected>area1
<input type='checkbox' name="area[]" value="area2" selected>area2
<input type='checkbox' name="area[]" value="area3" selected>area3
<input type='checkbox' name="area[]" value="area4" selected>area4
<input type="submit" value="Enviar datos" >
</form>

Despues recoges los datos:

foreach ($_POST['area'] as $datos){
echo $datos."<br>";
}
