Dynamic changes to a page

[dutcbhboy83]

I have a double drop down box, where the choice of the first box forces the page to reload and place different data in the second box. Kind of like having a country dropdown and state/province dropdown so depending on the country you pick you get a different list of states or provinces. This works great.

 

But the problem is that I also have a form on this page and if you start filling out the form and then change the drop downs all the data that you have already filled in goes blank, because the page refreshes so it only makes sense.

 

Does anyone have any suggestion to how I can get around this happening and reload all the variables that have already been filled in.

 

Thanks for you help in advance

What does this have to do with OOP? >_>

 

And you can either check out Ajax, or just echo out the existing form values in the value attribute of the input tag.

use ajax, that way only a specific place on your website gets refreshed, without touching any other data

thanks ignace ,

 

I checked out the tutorial from ajax, interesting, but I can't seem to figure out how to make it work with an sql query instead of a hard coded list.

 

If you know anything else about this it would be a big help.

 

Thanks again.
