Forleden manglede jeg en mulighed for at gemme diverse bruger notitser og senere hen udskrive dem. Jeg valgte at bruge sessions til formålet, således fejlene kan gemmes til de skal vises.
Mit projekt skulle kun have mulighed for, at gemme en enkelt notits før en ny blev genereret. Hvis dit projekt kræver mere end en notits, må du selv få udbygget scriptet. Jeg tænker, at det kunne klares vha. arrays.
Klassen er i sig selv ganske simpel. Jeg returnerer klassens objekt i nogle af funktionerne for at kæde metoderne sammen.
