Dank voor het aanpassen van mijn bericht, maar weet echt niet hoe ik dit moet doen.
Alles werkt alleen regel 141 geeft problemen
Wat voor problemen merk je dan rond lijn 141?
Als je wat specifieker bent, kunnen we ook specifieker antwoord geven.
lokaal krijg ik de foutmelding
Parse error: syntax error, unexpected '=', expecting ',' or ';'
Probeer zo online even als hij gezet is
sassiesstyle.nl
Code (php)
1
echo '<img src="' . WEBIMGDIR . $curr . '" alt="" />';
En tiep op regel 13 de letters van de sessienaam aan elkaar :
Code (php)
1
session_name(SS_ SESSNAME);
