Unknown PHP error


Recommended Posts

Hi I was wondering if anyone could help me with this error I am getting with this script, when I run the script in both explorer and firefox I am getting the following messages

Warning: usort(): The argument should be an array in /home/e-smith/files/ibays/Primary/html/mambo/components/com_events/events.php on line 1349

Warning: Variable passed to each() is not an array or object in /home/e-smith/files/ibays/Primary/html/mambo/components/com_events/events.php on line 1350

Now below is what is on both of these lines as well as the whole function it is in, the errors are comming from the usort and while lines but to me it seems fine. Can anyone see the problem?

function showCalendar ($rows,$year,$month,$day){
    global $mosConfig_offset,$database,$option,$Itemid;
    $cellcount = count($rows);   
    usort($rows, "sortEvents");
    while(list($key,$value)=each($rows)) {               
                $id_Array[] = $value->id;                         
                $title_Array[] = $value->title;
                $color_Array[] = $value->color_bar;
                $publish_up_Array[] = $value->publish_up;
                $publish_down_Array[] = $value->publish_down; 
                $reccurtype_Array[] = $value->reccurtype;
                $reccurday_Array[] = $value->reccurday; 
                $reccurweekdays_Array[] = $value->reccurweekdays;

Most likely the value of $rows is not an array

try using [url=http://au3.php.net/manual/en/function.print-r.php]print_r()[/url] to print out the array, it might give you an idea whats going on

eg: print_r($rows);

Ok ive tried printing the array but nothing is displayed, i've also looked for the var but cannt find it all I can find is the following in the script

$option = mosGetParam( $_REQUEST, 'option', 'com_events');
$task = mosGetParam( $_REQUEST, 'task', _CAL_CONF_STARTVIEW);
$mode = mosGetParam( $_REQUEST, 'mode', 'com_events');
$limit = intval( mosGetParam( $_REQUEST, 'limit', '' ) );
$limitstart = intval( mosGetParam( $_REQUEST, 'limitstart', 0 ) );

$offset = intval( mosGetParam( $_REQUEST, 'offset', 0 ) );
$catid = intval( mosGetParam( $_REQUEST, 'catid', 0 ) );
$agid = intval( mosGetParam( $_REQUEST, 'agid', 0 ) );
$keyword = mosGetParam( $_REQUEST, 'keyword', '' );

$pop = mosGetParam( $_REQUEST, 'pop', 0 );
