edit data from the database through checkbox

[misslois74]

i have seen one thread from this forum which manipulates data using checkbox my question is im using serialize to store data and unserialize to display data now my problem is what if i want to edit the data that is stored on the database what will be my approach....
here is my sample code:

//to store to the database:

$quer = "Select * from tbl_job_categories
						 where job_id = $vid";
				$result = mysql_query($quer) or die(mysql_error());
				$row = mysql_fetch_array($result);

				//$appid				= $_POST['app_id'];
				
				$idjob				= $_POST['id_job'];  //job posting
				
				$page				= $_POST['page'];
				
				$id				    = $_POST['jid'];    //for category of job
				
				$stats				= serialize($_POST['status']);
				
				//$news_title 		= addslashes($_POST['news_title']);

				//$applicants_name 	= $_POST['applicants_name'];

				$encoded_by 		= $_SESSION['usernameSESSION'];

				$date_encoded		= date('Y-m-d');

				$time_encoded		= date('G:i:s');

				$ip 				= $_SERVER['REMOTE_ADDR'];				

				if (is_array($_POST['status']))
				{
					    $sqlQuery = "INSERT INTO tbl_employers_shortlist (job_category_id, job_id, status, encoded_by, date_encoded, time_encoded, ip)
							    	VALUES ($id, $idjob, '$stats', '$encoded_by', '$date_encoded', '$time_encoded', '$ip')";

						if ($sqlQuery)
						{
							$result = mysql_query($sqlQuery);
						}
				}

//to view the data

while ($rows = mysql_fetch_array($result))
						{	
								
										$stats					= unserialize($rows['status']);
										$id						= $rows[job_id];
										foreach($stats as $s)
										{
												$ids = $s;
												if($ids == $rows[id])
												{
													echo "<span class='textmenu2'>$rows[name]</span><br /><br>";
																									}
																						}
		
										//echo "<a href='employers_shortlisted_hotelstaffs_cms.php?p=employers_shortlisted_hotelstaffs_ed&newsID=$newsID'>edit</a> &nbsp; | &nbsp; <a href='confdel.php?cur_page=$cur_page&newsID=$newsID'>delete</a>";
										
										echo "<a href='employers_shortlisted_cms.php?p=". $row[action3] . "&id=$id'>edit</a> &nbsp; | &nbsp; <a href='confdel.php?cur_page=$cur_page&id=$id&jobid=$row[job_id]'>delete</a>";
				
										echo "<br /><img src='images/break.gif'><br /><br />";
												
						}
				}

now if i want to edit the content of the field lets say uncheck the item selected how will i go about it
