multipart form

[Anon]

Hi there!

I'm going to do form which has two pages.
How can I do the following:

I ask at the first page that HOW MANY QUESTION DO YOU HAVE.
if answer is for example 4 then there will be 4 <input type=text> areas at the next page with nifferent name values. Is this possible?

I also ask some other question at the first page. How can I take those given parameters to the next page?

EXAMPLE:

FIRST PAGE
name?
email?
How many guestions <droplist values will be 1,2,3,4,5,6,7,8,9,10,...,30>

button <next page>

SECOND PAGE
name (from first page)
email (from first page)
-if there is 4 selected at first page-
<input type=text name=name1>
<input type=text name=name2>
<input type=text name=name3>
<input type=text name=name4>

END

I have MYSQL database and I know something about PHP

Well if you are calling the 2nd page directly from the first page then all of your form answers will turn up as variables either named the same as the form had them or you can find them stored in the global array $PHP_POST_VARS (if you used the post method).

It's a simple thing to read these variables and act on them. Any variables that you need to be passed from the 1st form through the 2nd form into the database can just be created as hidded form tags.

Yes you can, and I think you're on the right track. Your example is one step down from pseudo-code that could be translated into a php script. I would suggest that you use a form that posts to itself n times and adds the question to an array which is re-declared to be GLOBAL every time it posts to itself, and posts to another page on the last question, it may be easier to simply not ask how many questions, but put a checkbox (checked by default) to ask if there is going to be another question so that someone who has mentally counted 15 questions isn't stuck when he finally realizes he actually has 16 or 17. I can't give you an example right now (my computer and html, php & javascript manuals are at home) but if you dont get a fair example by the time i check this site tonight, I will post you a copy of a page that does something similar to what you want to do...
Good luck!
PS: the O'Reilly php pocket reference has a nice example of a self posting form...

It would be nice if you can send me the example!

Thanks

Sorry about that, I didn't go straight home after work, I will send you the example tonight, after adding some comments to it...

Here it is, hope line-wrapping doesn't make this un-readable. Most comments added for your convenience, get comfortable with php4
