Query Builder and Conditional Statements

$query = DB::select('thing')->from('things')->where('thing', '=', 'something');

if ($other_thing)
{
    $query->and_where('other_thing', '=开发者_运维百科', 'something else');
}

$query->order_by('thing', 'ASC')->limit(10)->execute()->as_array();

foreach ($query as $row)
{
    echo $row['thing'];
}

And what the problem is?

Well:

echo $row['thing'] -> nothing.
print_r($query) -> an object and not an array.

What am I doing wrong? Can someone help me on this? Please!

Thank you!

try this:

$result = $query->order_by('thing', 'ASC')->limit(10)->execute()->as_array();

foreach ($result as $row)
{
    echo $row['thing'];
}

To expand on the above answer, the problem is that the execute function is actually returning an instance of Database_Result. As the above post points out you are able to call various functions on this object that will then return the data in various formats (see the previous link for a full list of available functions)
