comment Getting a value in a dropdown box when updating a database value
Doing this actually doesn't make any difference. It just gives the same output. So somehow it doesn't recognize the ID of something?

comment Having a confirmation screen before deleting a database value
This is not working perfectly yet. Now it won't delete the value in the database anymore when I press "OK". Strange enough it does call on roosters_verwijderen.php, it doesnt delete the value.

comment Sending a sql request on the same page but missing the variable in the WHERE clause
Thank you andrewsi, you are indeed right. Now my query recognises the values. The only one it is missing, is activiteitID, which actually is the most important of all.

comment Sending a sql request on the same page but missing the variable in the WHERE clause
Ahhh, its correct that there is no datum in vrijwilliger, there is a datum in the table activiteit, which i'm trying to update. I changed this, now it returns my query: UPDATE activiteit SET datum = '', tijd = '', vrijwilligerID = '', werkzaamheid = '' WHERE activiteitID = '' so all my values are empty...

I echo'd the query. This gives: UPDATE vrijwilliger SET datum = '', tijd = '', vrijwilligerID = '', werkzaamheid = '' WHERE activiteitID = '' Unknown column 'datum' in 'field list'
