PHP array via multiple form inputs

Question

I've the following code :

$query = "SELECT * FROM items WHERE SUBSTRING(item_no, 1, ".$length.") BETWEEN 
'".$from_new."' AND '".$to_new."' ORDER BY item_no Desc";
$result = mysql_query($query);

$dd=array();
$ii=array();
$qq=array();
$aa=array();

if(mysql_num_rows($result)>0){
$num = mysql_num_rows($result);
?>

<form method="post" action="final_group_items.php">

<?php
echo "<table>";
for($i=0;$i<$num;$i++){
$row = mysql_fetch_array($result);
echo "<tr><td align=center>"; ?>

<input disabled  maxlength="2" type="text"
name="ii[]" value="<?php echo strtoupper($row['item_no']); ?>"><?php echo 
"</td><td align=center>";?> 

<input disabled maxlength="2" type="text" 
name="qq[]" value="<?php echo $row['qty'];?>"> 

<?php echo "</td><td align=center>"; ?> 

<input disabled maxlength="2" type="text" 
name="aa[]" value="<?php echo $row['actual_price'];?>"> 

<?php echo "</td><td align=center>";?>

<input required maxlength="2" type="text" name="dd[]" value="<?php echo 
$row['discount_price']; ?>">
<?php
echo "</td><tr>";
}   
echo "</table>";
?>

<input type="submit" value="Change Values">
</form>

Now when i click Submit it will open the final_group_items.php which has the follow testing code to make sure if all array (ii,qq,dd,aa) are not empty:

if(empty($_POST['qq']))
   {
     echo "No value inside";
     return false;

   }
   foreach($_POST['qq'] as $test)
   {
     echo $test;
   }
   return true;

so by testing all array's, the only one works is $_POST['dd']...Others outputs "no value inside" which I really don't know how or why? What should I do when I have multiple of fields having uniqe arrays and values.

Thank You

Because there's a disabled in the input tag of the others? — Ja͢ck

you jump in/out of php mode way too much. a lot of those echoes don't need to be done from inside php mode... — Marc B

your echo "<table>" is redundant.. just have <table> OUTSIDE of the php tag. it's not in a loop, it's not a dynamic string, so why waste cpu cycles in php mode to output it? — Marc B

This:

<input disabled maxlength="2" type="text" name="qq[]" value="<?php echo $row['qty'];?>">

Will prevent the browser from even posting the field at form submission, because disabled gets an implicit value of "disabled".

The attribute should be removed:

<input maxlength="2" type="text" name="qq[]" value="<?php echo $row['qty'];?>">

You mean for disabled ? I've removed disabled and tested it .. Same result.
