run snippet once?

Hi,

is it possible to run a snippet just one time? i am using the RandomImage snippet and i want to have a background image that is site wide but changes the next time you visit the page. So each browsering session it only runs once.


thanks,
Gareth

Can you explain a little bit more what you want?

Do you want that when a user enters the site the snippet get’s runned and then set’s a variable that will have the same value until the user leaves the website. Therefore you will have to make a snippet that creates a php session.

yes! that`s right, i want to run the randomImage snippet when the user first visits the site and than have that background image throughout the site.

i will look into php sessions, sorry i am not very good with php.

thanks

I agree with MediaGuy, a php snippet using a session var will work throughout the entire site for each visitor. Don’t think anything like this is available so you may need to code something yourself. The good news is that it is not too difficult, may even be possible to modify the randomImage snippet.

Yeah, he has to build in a check to see if a session variable is set, if it isn’t set you set it or else you do nothing

Only thing I don’t know is if you have to start a session or if MODx already does this for you?
