VNC stopt er mee :(
Elke keer 1 erbij
ik wil dat als ik toevoeg in de database dat bij 'test' elke keer 1 erbij komt maar dat je ook 1 eraf kan halen. Hoe doe ik dat?
@SanThe: Ik kijk ff of hij het doet
En ik heb nog een vraag, wat is er hier aan fout?
Ik krijg deze fout:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\Program Files\xampp\htdocs\php-fusion\addproject.php on line 22

Met mysql_affected_rows() kun je opvragen hoeveel records er zijn bijgewerkt. Uiteraard controleer je of de query uberhaubt wel is uitgevoerd.

hij heeft de goede waarde want projects werd 1, maar als ik die query nog een keer uitvoer blijft hij 1 :S
Offtopic: $date = date("d-m-Y H:i"); levert geen datum op, alleen maar bugs! Een datum sla je op in een DATE of DATETIME in het formaat yyyy-mm-dd hh:mm:ss. Een ander formaat is fout.
