Answer 1

Note:

• Made this code assuming you're using MySQLi Prepared Statement
• I explained the code in a comment form /* */
• I know that your HTML code is just a sample, but the value of your checkbox is set to only 1 . I hope that it's not. I also assume that the value of those checkboxes is coming from your database.
• Looks like you don't include your connection or don't know how to establish one, so I'll be updating my answer...right...now.
• I'm guessing that user has only two choices, 1 and 0, or enable and disable. So, again, I updated the code.
• Don't shout? (Just kiddin')

Your enableprofile1.php should look like this:

<?php

/* ESTABLISH CONNECTION */

$con = new mysqli("YourHost", "YourUsername", "YourPassword", "yourDataBaseName"); /* REPLACE NECESSARY DATA */

/* CHECK CONNECTION */
if (mysqli_connect_errno()) {
  printf("Connect failed: %s\n", mysqli_connect_error());
  exit();
}

if(isset($_POST["save"])){ /* IF SAVE BUTTON IS CLICKED */

  /* STORE THE PASSED DATA FROM YOUR FORM VIA POST */
  $enable = $_POST["enable"];
  $hiddenid = $_POST["id1"];
  $total = count($enable); /* COUNT TOTAL ARRAY */

  for($x=0;$x<=$total;$x++){ /* RUN A LOOP THAT CHECKS ALL DATA */

    if(!empty($enable[$x])){ $todo=1; } /* IF ENABLE IS CHECKED */
    else { $todo=0; } /* IF ENABLE IS NOT CHECKED */

     $stmt = $con->prepare("UPDATE yourTable SET yourColumn = ? WHERE yourID = ?"); /* REPLACE NECESSARY CONNECTION VARIABLE, TABLE NAME AND COLUMN NAME */
     $stmt->bind_param('ss', $todo, $hiddenid[$x]); /* BIND PASSED DATA TO THE QUERY */
     $stmt->execute(); /* EXECUTE QUERY */

  } /* END OF FOR LOOP */

} /* END OF ISSET SAVE */

?>

Add this to your form:

...
<?php
  $counter=0;

//user id 
echo '<input type="hidden" name="id1[$counter]" id="id1[]" value="'.$sn.'"  />';

// user id

//enable checkbox
echo '<input type="checkbox" name="enable[$counter]" id="enable[]"  value="1" if($en=='1'){ echo 'checked';}  />';

$counter=$counter+1; /* INCREMENT $counter FOR EVERY LOOP */

?>
...
