hallo iedereen,
Ik ben bezig met een script te maken wat tot bedoeling heeft om het aantal werkdagen dat iemand moet wachten te berekenen. Dus de bedoeling is:
iemand geeft een datum in (liefst heb ik dat er standaard die van vandaag staat) en deze moet dan kunnen selecteren of hij of zij standaard of premium is (60 werkdagen of 30 werkdagen wachten) en als hij/zij dan op berekenen drukt moet de datum na de 30 of 60 werkdagen eruit komen. Ik ben niet echt gevorderd op gebied van php, en heb een aantal bestaande scripts in combinatie van eigen html samengegooid en kom tot onderstaand resultaat voorlopig :P
