Accessing Arrays in HTML

["Shaun" <shaunthornburgh@xxxxxxxxxxx>]

Hi,

I am trying to create a form on my page. The idea is that for each project 
people can select whether they are allocated for scheduling, non_scheduling 
or both. Here is an example of my form:

<tr>
   <td><input name="project[44][Scheduling]" type="checkbox" 
value="44"></td>
   <td><input name="project[44][Non_Scheduling]" type="checkbox" 
value="44"><td>
   <td>Project 1</td>
  </tr>
    <tr>
   <td><input name="project[25][Scheduling]" type="checkbox" value="25"><td>
   <td><input name="project[25][Non_Scheduling]" type="checkbox" 
value="25"></td>
   <td>Project 2</td>
</tr>

I am trying to access the arrays in the HTML as follows:

if (is_array($_POST['project'])){
   $fields='';
   $values='';
   foreach ($_POST['project'] as $project_id => $value) {
    $fields[] = $project_id;
    $values[] = $value;
   }
   $i = 0;
   $num_elements = count($fields);
   while($i < $num_elements){
    if(($values[$i]) != 0){
     echo '<br />$i = '.$i.'<br />';
     print_r($fields);
     $query = ("INSERT INTO Allocations (
           User_ID,
           Project_ID,
           Scheduling,
           Non_Scheduling
          ) VALUES (
           '".$user_id."',
           '".$fields[$i]."',
           '".$fields[$i][0]."',
           '".$fields[$i][1]."',
          )");
     echo $query.'<br />';
    }
    $i++;
   }
  }

However I can't access the 'Scheduling / 'Non_Scheduling' part. Can anyone 
see where I am going wrong here?

Thanks for your advice
