You have a lot of detail for folks to analyze just to give you an answer.
If I get the gist of your question, here is the genesis of an approach.
Put something like this in your loop that generates the table rows. The checkbox can be anywhere in the row that looks
good.
echo "<input type=\"checkbox\" name=\"row$i\" value=\"$value\">";
$i++;
Then when you process your $_POST, you'll see all the $_POST[rowx] {"x" is the row number} that were checked by the user.
