PHP Mysql Statement - multiple statements

I have a PHP page that displays the results of a mysql query. each returned record is assigned a check box with the a value equal to the Row ID column.

the mysql statement in place inserts the selected rows into a new table.

I would like to add a second mysql query that updates the status of another table where the selected ID's match. the query is below:

UPDATE despgoods_alldetails,loaddetails SET despgoods_alldetails.locstatus ='LoadCreated' WHERE despgoods_alldetails.despgoodsid = $val

The page PHP Code that works currently is( I am aware of some incorrect code):

> <?php
>     mysql_connect("localhost", "hulamin_hulamin", "Hulamin2011")or die("cannot connect");    
>     mysql_select_db("hulamin_loc")or die("cannot select DB");
>     $sql="SELECT `despgoodsid`,`crtd dept`,`customer`,`loc cust rel`,`case no`,`gross mass`,`case width`,`case length` from
> despgoods_alldetails where transporttypename= 'localpmb' and
> locstatus='unplanned' and customer <> 'customer'";
>     $result=mysql_query($sql);
>     $count=mysql_num_rows($result);   putenv("TZ=Africa/Johannesburg");   ?> <table border=0>
>     <tr>
>         <td>
>             <form name="form1" method="post">

How can I add my update statement to run in addition to the select statement for each selected row?

Any help is appreciated.

Thanks and Regards, Ryan Smith

I though I would post the complete working code here. Big up to @mishu for all the help and patience.

<?php
    mysql_connect("localhost", "user", "password")or die("cannot connect");    
    mysql_select_db("database")or die("cannot select DB");
    $sql="SELECT `despgoodsid`,`crtd dept`,`customer`,`loc cust rel`,`case no`,`gross mass`,`case width`,`case length` from despgoods_alldetails where transporttypename= 'localpmb' and locstatus='unplanned' and customer <> 'customer'";
    $result=mysql_query($sql);
    $count=mysql_num_rows($result);
    putenv("TZ=Africa/Johannesburg");

?>
<table border=0>
    <tr>
        <td>
            <form name="form1" method="post">

you could create a trigger that would fire when data is saved in the secondary table; check mysql manual for triggers if you think this might be what you need
