php code to rearrange row order in database on update of selected row -

-

tablename: news

column:

headline, send_sub_top, sub_top_priority.

below table structure in database.

i need when update selected row form. updates send_sub_top = "inactive" in database , rearrange order of sub_top_priority column in database.

for example:

if delete row 3 in database update send_sub_top = "inactive" of row 3 , sub_top_priority = 0 of row 3 , rearrange order of sub_top_priority column in ascending order 1,2,3,4.

i create code update send_sub_top column = inactive in database not rearrange sub_top_priority order...

my code example -- code update send_sub_top = inactive , keep sub_top_priority column order like...

after deleting 3rd row 1,2,4,5. need 1,2,3,4.

id  headline            send_sub_top               sub_top_priority   1                    active                            1  2    test                active                             2  3    nice                active                             3   4    great               active                             4  5    demo               active                              5

plz me....thanks in advance..

below code...

<?php                                   foreach($sub_top_select $sub_top)                 {                                        ?>             <li><a href="javascript:return(0);" remove_sub_top_news="<?php echo $sub_top['id']; ?>">                 <img src="img/error.png" height="14px" width="14px" /></a></li>                 <?php } ?>

php code update inactive in database...

but need rearrange order of sub_top_priority column in ascending order 1,2,3,4.

<?php if(isset($_post['remove_sub_top_news']))     {            $id = mysql_real_escape_string(trim(htmlspecialchars($_post['remove_sub_top_news'])));               $sql = "select id,send_sub_top news id='$id'";         $result = mysql_query($sql);                 $row = mysql_fetch_assoc($result);               mysql_query("update news set send_sub_top='inactive' id=".mysql_real_escape_string(trim(htmlspecialchars($_post['remove_sub_top_news']))));                if(mysql_affected_rows() > 0)         {                        $_session['message'] = "news removed subtop successfully";             header("location:sethomepage.php");             exit;         }            } ?>

first update send_sub_top value.

then select data table condition set_sub_top = 'active' , order sub_top_priority ascending.

then looping whole data of select query update sub_top_priority increment of 1.

nb : method if there not data in table.
