I am getting this error

[21-Aug-2007 17:09:15] PHP Warning: Invalid argument supplied for foreach() in /path/Parts.php on line 168


Parts.php


if( $sqlHelper->execute() )
{
while( $sqlHelper->db->moveNext() )
{
$subArray[] = $sqlHelper->db->record;
}
}

$key = $subArray['part_id'];

if( $convertChars )
{
line 168 foreach($subArray[$key] as $k => $val)
{
$subArray[$k] = htmlspecialchars($val, ENT_QUOTES, 'UTF-8');
}
}


please pardon sqlhelper... its part of the framework in the system to run the sql query
any help?
thanks

In almost all cases, that error comes up when the variable passed through the foreach loop is not an array.

In this case, I believe you are for some reason using the $key index of the array instead of the array itself. It is possible that the $key index is an array in itself, but that doesn't appear to be the intent of your script.

Use: foreach($subArray as $k => $val).

Actually the $key is an array in itself, starting on the next line. but anyway that did it. Thanks
