try pdo, I will copy you my crud class and change the way you loop

if you looped thru 2 get d checkboxes, u shud add thier IDs as their values this way u can identify whch box was selected. And the value for the name attribute shud av an array notation e.g <input type="checkbox" name="course_id[]" value="(id e.g 1)"> . On the server side use or loop thru $_POST["course_id"][] to grab all selected courses. Make sure they have IDs on the database or any other identifier. Was it helpful?

To start with
placing Nigeria in a group with England, Portugal and Spain. Ordinarily 99% of NIGERIANS would rule the Super Eagles out of the world cup months before the world cup even start and when they fullfil that expectation we become angry and criticize them....what are we now angry for?

The exit of Spain and England tells us that we don't have hope but rather we have assurance; plainly it is crystal clear that no team is infallible, no team is invincible, no team is GOD.
Every team starting from the ones we fear most to the ones we ignore have fears.
Check out comments by players and you'd see that the likes of Messi, Neymar and Robben that we tremble before are all afraid of the teams they used to look down on, but they mask it with confidence based on past records and the fear in us.
We have improved, like it or not. If we can reply every goal of the Argentines (some already lost hope during the match, believe me; it was a narrow defeat), then we can beat the french.
But if all you can see is the elite french players [highest 2 or 3] as if they can win the match by themselves; na for your pocket.
As for me this is my prediction:
