Calendar code with checkboxes on each day of the month to book meals:

I have this code to insert into the database table and I know it is working:
<?php
if(isset($_POST['submit'])){//to run PHP script on submit
if(!empty($_POST['arrachar'])){
// Loop to store and display values of individual checked checkbox.
foreach($_POST['arrachar'] as $selected){
$string = implode(' ', $selected);
$sql="INSERT INTO marcacao (arrachar) VALUES('$string')";
$r = mysqli_query($conn,$sql);
}
}
}
?>
My problem is that I can not insert into the database the value faults of the checkbox selected in the calendar.
One of the Solutions would be this:
for($day=1,$days_in_month=gmdate('t',$first_of_month); $day<=$days_in_month; $day++,$weekday++){
if($weekday == 7){
$weekday = 0; #start a new week
$calendar .= "<form action='' method='POST'></tr>\n<tr>";
return $calendar."<input type='submit' name='submit' value='Marcar'>
</form></tr>\n</table>\n";
In this solution I add <form action='' method='POST'> and <input type='submit' name='submit' value='Marcar'> as shown in the above code.
