hi jshultz...
this is how i've approached joined output. maybe it will help you:
Code:
// this is a very simple sub-summary function that will give you nested arrays
// call it like this
// $res is a ci query result object
$new_array = nest_flat_records($res,'name_of_field_result_is_sorted_on','name_of_field_in_joined_table');
// take the output from a join
// (where the records are duplicated except
// for one data point) and nest the
// desired data point $pluck_out
function nest_flat_records($res,$group_by_value,$pluck_out)
{
$new = array();
$sub = array();
$prev_group_by_value = '';
foreach($res as $k=>$r)
{
if ($r->$group_by_value === $prev_group_by_value)
{
// add a sub item
$sub[] = $r->$pluck_out;
}
else
{
// it's first record or the next group
if (! $k) // first
{
$kp = $k;
$sub[] = $r->$pluck_out;
unset($r->$pluck_out);
$new[$kp] = $r;
}
else // subsequent
{
// store the previous group's
// sub array, then re-initialize it
$new[$kp]->pluck_out = $sub;
$kp = $k;
$sub = array();
$sub[] = $r->$pluck_out;
unset($r->$pluck_out);
$new[$k] = $r;
}
}
$prev_group_by_value = $r->$group_by_value;
}
// cap it with the last one
$new[$kp]->pluck_out = $sub;
return $new;
}
