Inserting checkbox values into database

I need help for this problem that i\'m trying to solve for a while (i\'m new in PHP). I have a form with several checkboxes which values are pulled from a database. I manage

Answer 1

This is the loop that I needed. I realized that I need a loop through each key with the $i variable.

if(isset($_POST['id_dodatoci'])){
    $id_dodatoci=$_POST['id_dodatoci'];
    $arr_num=count($id_dodatoci);
    $i=0;
    while ($i < $arr_num)
    {
        $query="INSERT INTO `dodatoci_hotel`(id_dodatoci,info_id) 
            VALUES ('$id_dodatoci[$i]','$info_id')";
        $res=mysql_query($query) or die('ERROR INSERTING: '.mysql_error());
        $i++;
    }
}
