Hi Thomas,
very good book, but with many errors.
Till now I solved errors by myself, but this one I don't have any idea that to do:
A PHP Error was encountered

Severity: Notice
Message: Uninitialized string offset: 0
Filename: views/admin_cat_home.php
Line Number: 14


Please help.
Thanks

I think most of errors of the claudias sample codes coming from that the codes were written for error reporting E_ALL & ~E_NOTICE. But the index.php set up the error reporting as E_NOTICE.

If the author reset the index.php error reporting as E_ALL & ~E_NOTICE. Most of the errors will be gone.

This leads to my another question, should we program for error proof as error reporting E_ALL or for error proof as error reporting E_ALL & ~E_NOTICE?

Go back to your issue, I am not sure, but if your try to reset error reporting to "E_ALL & ~E_NOTICE", my guess is that error will be gone.

By the way, did you empty the categories table and then this error pop up?

I already solved the issue, and put the solution here(some why is deleted now).

The issue is some problems in code(maybe even with CI because query from controller was bringing wrong results-very strange ). I replaced ->get_array with ->result() and loop content. Now working correct.
New code:
function getAllCategories()
{
$data=array();
$Q=$this->db->get('categories');
if($Q->num_rows() > 0){
foreach($Q->result() as $row){
$data[]= array(
'id'=>$row->id,
'name'=>$row->name,
'shortdesc'=>$row->shortdesc,
'longdesc'=>$row->longdesc,
'status'=>$row->status,
'parentid'=>$row->parentid
);
}
}
$Q->free_result();
//check
return $data;
}

That is strange. result_array() or result(), it shouldn't make any difference here.

Cannot repeat the error you have either.

Generally you right,but it was very strange thing.
result_array() was giving me wrong result, maybe because it was trying extract multidimensional array from row to another array and in some way do it wrong. In repaired code I create multidimensional array before pass values.

That's....bizarre. The two should be aliases for one another.

yes, we had some last minute changes go into the book which resulted in some mismatches between text examples in the book and actual code on the CD, which has been a bit frustrating for me.....again, I apologize for the mixups.
