Onderstaand script kan een foto uploaden + beschrijving naar de database sturen. Ook zit er een kleine validatie op het upload formulier, maar hetgeen dat niet lukt is om de geüploade afbeeldingen naar mijn image/ en image/tn/ mappen te schrijven.
Heeft iemand een idee wat ik fout doe? Zo ziet alvast de structuur eruit:
images/
-tn/
css/
js/
index.php
config.php
functions.php
database.php
