I have a PHP page, that on clicking the submit button process a few MySQL queries.

in MySQL PHPMyAdmin the query works 100% and both queries execute. However, when in my PHP Code the queries do not execute.

Any help would be appreciated, I bet this is a simple one for decent PHP coders.

Thanks in advance Ryan.

My Code is:

<?php
    mysql_connect("localhost", "hulamin_hulamin", "Hulamin2011")or die("cannot connect");    
    mysql_select_db("hulamin_loc")or die("cannot select DB");
    $sql="SELECT `dispatcharea`,`customer`,`casenumber`,`weight` from loaddetails where loadid = 0 order by dispatcharea";
    $result=mysql_query($sql);
    $count=mysql_num_rows($result);
?>

    <tr>
        <td>
            <form name="form1" method="post">
                <table border=1>
                    <tr>
                        <td width=150>Dispatch Area</td>                        
                        <td width=300>Customer</td>  
                        <td width=150>Case Number</td>
                        <td width=100>Weight</td> 
                    </tr>
<?php
    while($rows=mysql_fetch_array($result)){
?>
                    <tr>
                        <td><?php echo $rows['dispatcharea']; ?></td>
                        <td><?php echo $rows['customer']; ?></td>
                        <td><?php echo $rows['casenumber']; ?></td>
                        <td><?php echo $rows['weight']; ?></td>
                    </tr>    

<?php
  }
?>      
</table>            
    <input name="Next" type="submit" id="Next" value="Next">                

<?php
if($_REQUEST['Next']=='Next') {
    {
        $sql="update loaddetails set loadid= (select max(loadid)+1 from loadcounterid) where loadid=0; update loadcounterid set loadid= (select max(loadid) from loaddetails) where loadid>0;";

        $final=mysql_query($sql);
        if($final)
        {
            echo "<meta http-equiv=\"refresh\" content=\"0;URL=planlocalpmbstep3.php\">";
        }
    } 
}

?>
</table>

</form>
</td>
</tr>
</table>

Thanks again,
Ryan

    I think that this is likely to be your problem

    while($rows=mysql_fetch_array($result)){

    Should be

    while($rows=mysql_fetch_assoc($result)){

    To refer to them as

    echo $rows['dispatcharea'];

    EDIT:

    You also need to split both of your queries up in to two separate queries, because you cannot run two queries in one mysqli_query() tag.

    You will need to split them as shown below:

     // First update query
 $sql1="update loaddetails set loadid= (select max(loadid)+1 from loadcounterid) where loadid=0";

// Second update query
$sql2="update loadcounterid set loadid= (select max(loadid) from loaddetails) where loadid>0";

// Run both queries independently
$final_query1 = mysql_query($sql1);
$final_query2 = mysql_query($sql2);

// Check for query success
if ($final_query1 && $final_query2)
{
   // Success running the queries
}
else
{
   // Unsuccessful running the queries
}
