i have this code which i use to print some fields from the database.

My problem is that i get this error about foreach invalid argument supplied and a mysql fetch array problem.

The code is this:

foreach( $checked1 as $key => $value){
    echo "<th> $value </th>";
}
echo "</tr></thead>";

while($row = mysql_fetch_array($result)){

Where $checked1 is an array

$checked1 = $_POST['checkbox'];

What's the problem here?

Thanks..
