Never mind - I figured it out.
While I was traversing like this:
foreach ($this->code['assign'] as $assign => $details)
{
foreach ($assign['codeapply'] as $codeapply => $ca_details)
{
}
}
I had set up $assign to be the key value, and likewise not be an array. I
changed it to:
foreach ($this->code['assign'] as $assign => $details)
{
foreach ($details['codeapply'] as $codeapply => $ca_details)
{
}
}
and it worked beautifully. Thanks to all of you who got me going in the
right direction.
