check box update problem

[pixeltrace]

guys,

 

i need help,

 

i have a checkbox for 'j_type' which is in my update form page.

on that form i have a row there

that will display the current job type

 

now in my process page i have a if else condition there that if

none of the check box was checked the current value on the current job_type

will be the value to be updated.

 

below is my codes for the update form page

 

<form action="job/updatejob.php" method="post">
                      <tr>
                        <td align="right" valign="top" class="text6">Job Type  :</td>
                        <td> </td>
                        <td class="text3">

					<input type="checkbox" name="jtype[]" value="Permanent"> Permanent 
                          
                          
<input type="checkbox" name="jtype[]" value="Contract"> Contract                          
<input type="checkbox" name="jtype[]2" value="Part-Time" />
Part-Time</td>
                      </tr>
                      <tr>
                        <td align="right" valign="top" class="text6">Current Job Type  :</td>
                        <td> </td>
                        <td class="text3">
					<?
					$ljtype = explode(", ",$j_type);
					echo implode(",",$ljtype) ;
					?>						</td>
                      </tr>
                      <tr>
                        <td rowspan="2"> </td>
                        <td rowspan="2"> </td>
                        <td><input type="submit" name="Submit" value="save" />
					<input type="hidden" name="username" value="<? echo "$username"; ?>">
					<input type="hidden" name="jobid" value="<? echo "$jobid"; ?>">	
					<input type="hidden" name="ljtypt" value="<? echo "$ljtype"; ?>">
										</td>
                      </tr>

 

 

and this is the condition code that i have in my updatejob.php

<? 
$ljtype = $_GET['ljtype'];
$jtype = $_POST['jtype'];

if ($jtype == "") {
$jtype = "$ljtype" ;
} else {
$jtype = implode(",\n", $_POST['jtype']);
}

include '../db_connect.php';

$sql="UPDATE job_ads SET j_position='$jposition', c_name='$cname', cperson='$cperson', specialization='$specialization', level='$level', industry='$industry', c_description='$cdescription', j_requirements='$jrequirements', j_responsibilities='$jresponsibilities', j_type='$jtype', salary='$salary', location = '$location', country='$country', date_posted='$dateposted', date_closed='$dateclosed', j_status='$jstatus', remarks='$remarks', staff_updated='$staff_updated', date_updated='$date_updated'  WHERE jobid='$jobid'";
	mysql_query($sql) or die("error:".mysql_error());

?>
