Var omzetten PHP
Nu wil ik met deze kilometers verder gaan programmeren in PHP, in een variabel $km, en ik heb al rond gekeken hoe ik dit moet doen maar nergens krijgt ik de gegevens uit JS naar een variabel in PHP omgezet. Wie kan me helpen, wat is de beste manier?

Je zou het zo kunnen doen: Kilometers zijn <span id="afstand"></span> en dat kost 25 liter benzine om te rijden...
En anders moet het met een pagina refresh. Dus javascript km opslaan in cookie/sessie en die dan weer door php uitlaten lezen..

Bedankt voor je reactie. Had dat over client/server side ook al gelezen. Kan je me vertellen hoe ik die km vanaf Java in een sessie moet zetten?
Groet,
Hans
Bedankt !
