using a select field to post a form

[Anon]

hi all,

the situation is: I have a form with a select-field in it the user can select e.g different beers. After the user made clear in which sort of beer he is intrested, the formpage need to change a little bit... I can handle it by sending the user to a new URL using the onChange event of the select-field but then I loose all the infos he already typed in (and that is one of the frustrating things on the web :-( . The problem is that not only the look of the page changes (I could do that with JS) but also the values of another select-field.
So it would be perfect if I could use the onChange-Event of the select-field to post the form to a script where I build the "new" page using the "old" typed in Userinformation but I haven't found another way to post a form without a button or image - if you know one I would be very glad if you let me know.
But the important thing is to keep the userinformation, so if you got a hint or a example-script or or or ... how to do it just tell me!!

Thanks a lot for reading all this (should have become an author instead of a developer :-) ...

I´m completely with you concerning the author - developer thing!
🙂
But unfortunatly I don´t have a clue concerning your problem...

But one idea:
You could execute a silent php script which saves the information already entered in a file/DB via a mouseOver Event on the jumpmenu. (if the user has already entered stuff)

Or just have two different pages (maybe frames?!?)... this would be the easiest way I guess... but since your idea sounds really good in my ears I wouldn´t want to go that way... 🙂

Good hunting

The problem is that not only the look of the page changes (I could do that
with JS) but also the values of another select-field.

you can do this with JS. define a javascript array, indexed by the values of the first select. each element of this array is then another array which contains the options for the second select corresponding for the entry in the first select. (did that make sense?) then when you make a selection in the first select, write the appropriate elements to the options array of the second select.

clear as mud ;-)

and, of course, you can get php to build all these arrays for you from a database 🙂

Hi Fab,

i'm doing it shorter this time :-)
I've done it, using JS and PHP, they work together quite well and though I'm not really satisfied with this solution it works ok for the moment...
I used the submit() method of JS (formname.submit() for those who don't knew <- like me yesterday :-) to submit the form with the onChange event of the select-field. The action-script is $PHP_SELF so at the beginning of my script I just check a few inputs and build the page then based on what i need (the parts of the page that need to change are dynamic and get there values at the beginning...)
In case you want to know more mail me...
And thanks a lot for your help and suggestions!!
