Code (php)
Kan ik op een simpele manier met onChange of onClick zoiets bereiken na een $_POST? Of is het handiger om met onClick de URL aan te passen middels een $_GET? Dit heb ik al geprobeert, echt zonder succes.
Gr,
Thomas

Parse error: parse error, expecting `T_OLD_FUNCTION' or `T_FUNCTION' or `T_VAR' or `'}'' in download.php on line 54
Ik denk vanwege de "protected" waarde in de CLASS core. Desallniettemin, bedankt voor je professionele oplossing! :)
^^ Tutorial van Jan Koehoorn.
Hiermee moet het wel lukken denk ik.

Bedankt voor je mooi OOP functie, echter krijg ik nu een error die mij dwingt om over te stappen naar PHP 5.0 of hoger:

Om hem geschikt te maken voor PHP4 kun je het volgende doen:
1) overal waar protected staat, maak je er var van
2) verander de functienaam __construct in de naam van de class (respectievelijk core en selectbox)
3) in de constructor van de selectbox class verander je dit:
parent::__construct ();
in dit:
parent::core ();
Let er op dat je de constructor van de core class ook aangepast hebt.
