array problem

[raj_2006]

Hi all,

I am facing a problem of arrays.The fact is that I am getting the array values but when i am running 2 arrays under a single for loop then I am only getting null values for the quantities....lets give you the code so that you can understand where the problem lies.

output of
echo "Key1: $key1; Value1: $value1<br />\n";
echo "Key2: $key2; Value2: $value2<br />\n";

is

Key1: 0; Value1: 1475
Key2: 0; Value2:
insert into temp_cart(cart_id,pid,quantity,item_price,net_total) values('1','1475','','180.05','0')
Key1: 1; Value1: 1476
Key2: 1; Value2:
insert into temp_cart(cart_id,pid,quantity,item_price,net_total) values('1','1476','','196.74','0')
Key1: ; Value1:
Key2: 2; Value2: 3
Key1: ; Value1:
Key2: 3; Value2: 5

As you see I am not getting the net_total and quantity

//if the form is submitted
if(isset($_POST['image1_x']))
{
$pid=$_POST['pid'];//product id
$quantity=$_POST['quantity'];
$item_price=$_POST['item_price'];
if($pid!="")
{
        for(
             ;
             list($key1, $value1 ) = each( $pid ) ,
             list($key2, $value2 ) = each( $quantity )                  
             ;
        ) {        
    echo "Key1: $key1; Value1: $value1<br />\n";
    echo "Key2: $key2; Value2: $value2<br />\n";            
            foreach($item_price as $k=>$v)
            {                    
            list($v1,$v2)=explode("#",$v);//(price and pid)
               
                                       if($value1!="")
            {                            
            if($v2==$value1)//if pid==pid
            {
            $net_total=$value2*$v1;                                            
            $s_pro="select pid from temp_cart where pid='$value1' and cart_id='$cart_id'";// TO SEE IF THE SELECTED PRODUCT IS ALREADY IN THE CART OR NOT
            
            $q_pro=mysql_query($s_pro) or die(mysql_error());
            $numrows=mysql_num_rows($q_pro);                    if($numrows=="")
            {            
            //echo "insert into temp_cart(cart_id,pid,quantity,item_price,net_total) values('$cart_id','$value1','$value2','$v1','$net_total')";
            $s_temp="insert into temp_cart(cart_id,pid,quantity,item_price,net_total) values('$cart_id','$value1','$value2','$v1','$net_total')";
            $q_temp=mysql_query($s_temp) or die(mysql_error());
            header("location:cart.php");            
            }
            else
            {
            $err=1;//one of the selected product is already in the cart
            }
            }
            }                                         
            }                                            
          }        
}          
else
{
$emp=1;//no product has been selected
}            
}

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

Please suggest how to get the values from the quantity array

Thanks in advance for your co-operation.
