View source for BeBot Standard Return Array

====== BeBot Standard Return Array ======
Many BeBot functions return an array with a standard format. There is currently no policy that module developers follow this format when their function(s) return data. 

==== Return Array Elements ====
There are three elements in a BeBot Standard Return Array: bool error, string errordesc, and mixed content. 

<code php>
$return = array('error' => FALSE, 'errordesc' => '', 'content' => '');
</code>

=== Example Usage ===
<code php>
function return_parameter($parameter)
{
    $return['error'] = FALSE;
    $return['errordesc'] = '';
    $return['content'];
    if (is_null($parameter))
    {
        $return['error'] = TRUE;
        $return['errordesc'] = 'parameter passed to function return_parameter is null.';
    }
    else
    {
        $return['content'] = $parameter;
    }
}

function calling_function($input)
{
    $result = $this -> return_parameter($input);
    if ($result['error'])
    {
        return $result['errordesc'];
    }
    else
    {
        return $result['content'];
    }
}
