Hello,

I am having a real hard time to understand query strings!!

Currently I pass data/variables from one page to the next using hidden inputs.
This works 100%, but I'm running into some trouble with it now. What I want to do
is send an email address field from page1 to page2, so that I can then use that variable(email)
in page2, in sql statement for example.

Can someone please give me some simple example code - I'm sure I'll then be
able to figure it out.

Thanks,
T

I'm not sure I understand completely...

You're trying to send an variable (that holds the email address) from one page to the next...

If you're using forms...

'// In page 1

<form name="whatever" action="post" method="page2.asp">
<Input Type="text" name="emailaddress" size="50">
<Input Type="submit">
</form>

'// In page 2

<html>
<p>The email you entered was: <%=Request.Form("name")%></p>
</html>


If you passed the data in a querystring (which I don't think you are in this case) you would reference the variable as:

<html>
<p>The email you entered was: <%=Request.QueryString("name")%></p>
</html>


Basically the difference is that if you pass things from a form (using POST) they are in the Request.Form collection and if you use GET (like a querystring) then they are in the Request.QueryString collection.

Hope this helps...

Maybe I didn't explain properly or what I want to do is NOT query string.

I basically want to achieve something like this forum for instance - look in the url - they send some info from one page to the next.

http://forums.vb-world.net/showthread.php?s=&threadid=59054

The email address which I want to send to the next page is not entered in a input box. I read this from my db. I suppose I now can put this email (which I just read from db) into a input/hidden input and the post it, but I am trying to learn some other stuff - "querystrings" , for now!!

Thanks,

Ok. Sorry, I didn't understand what you were trying to do.


To use querystrings just call the page you want and append the querystring to it...



<html>

<p>Clicking on this link will pass the email turfbult@vbworld.com to emailprocess.asp</p>

<a href="emailprocess.asp?email=turfbult@vbworld.com">Click here</a>

</html>


Does that make sense? You basically add the key-value pairs to the url...

somepage.asp?variable1=value1&variable2=value2&variable3=value3...

You can do this in your ASP pages by doing stuff like...

<a href="process.asp?<%=variable1%>=<%=value1%>">Click here</a>

(Where variable1 and value1 are variables)

The information you pass this way will then be in the Request.QueryString collection... which means that you to get the values you:



vEmail = Request.QueryString("email")



Hopefully that's more on target than last time...
