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

I have this code to enter into the database table and I know it’s 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,$sql);
}
}
}
?>
My problem is I can’t get into the database value of the selected checkbox in the calendar.
One of the Solutions would be this:
for($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 the <form action='' method='POST'> and <input type='submit' name='submit' value='Marcar'>as shown in the code above.
