Take this for an example :
This script fills part of a form with checkboxes named C1,C2, ect
$cnt=0;
for ($i=1;$i<=$n_alunos;$i++) {
if ($cnt==0) {
print "<tr>";
}
print "<td><input type=\"checkbox\" name=\"C$i\" value=\"on\">Aluno
$i</td>";
$cnt++;
if ($cnt==$colunas) {
print "</tr>";
$cnt=0;
}
}
This script receives the result from the previous form, and checks wether
checkbox C2 is set or not
if (!empty($_POST['C2'])) {
$b = $_POST['C2'];
}
else {
$b = "vazio";
}
An example ...
