Dynamic Form Problem / Session Variables!

whats the x stand for, or what should it stand for in my code?

Can you give an example using the fields and names I have given, if possible please.

The x stands for nothing its a kinda shorthand way of referencing the previous form elements. (I made an error with using x.name)
Try this simple example

<form method=post action=ee44.asp>
Box 1 <input type=checkbox name=chk_box1 value=1>
Box 2 <input type=checkbox name=chk_box2 value=2>
Box 3 <input type=checkbox name=chk_box3 value=3>
<input type=submit>
</form>

ee44.asp
<%
for each x in request.form
   if left(x,4)="chk_" then
      session(mid(x,5)) = request(x)
   end if
next
response.write "Box1 = " & session("box1") & "<BR>"
response.write "Box2 = " & session("box2") & "<BR>"
response.write "Box3 = " & session("box3") & "<BR>"
%>

Which ever checkboxes you select they will be placed into a session variable and printed on the next page.

Is there an easier way for me to do this than using session variables then. I open to sugegstion.

session variables were used origionally due to the form covering 3 pages.

If theres a simpler way of doing this then I am willing to alter the design.

SimonWGoldsmith ,

Try this approach...

Create a dynamic checkboxes with the same name but the value will  the actual recordset

<input type="checkbox" name="chkbox" value="<%=(rsRegionAsscociation.Fields.Item("RegionName").Value)%>">

try to check out the link of rmore info...

http://oldlook.experts-exchange.com/Web/Web_Languages/ASP/Q_20450556.html

Or if you just one session value then you can try this....

Now what you just need to do is to session this value...

like for example

session("chkbox") = request.form("chkbox")

If you want to retrieve the values of the session... since making the checkbox the same will make it a comma seperated string

Then you will just manipulate using split function... like this


arraysesssion  = split(session("chkbox")

for i=Lbound(arraysession) to Ubound(arraysession)

response.write arraysession(i)

next

This way you will only deal and track one session variables...

HTH...

HAppy programming...

OOPS some typo....

<%
arraysesssion  = split(session("chkbox"))

for i=Lbound(arraysession) to Ubound(arraysession)

response.write arraysession(i)

next
%>

Happy programming...

As for not using session variables for a three page form, take Gary's code:

for each x in request.form
   if left(x,4)="chk_" then
      Response.Write "<input name='" & X & "' value = '" & request(x) & "'>"
   end if
next

These will make hidden form variables that will be passed to the third page, and can then be accessed again using Garys Loop

Good addition kblack

SimonWGoldsmith,

I think the approach that I had given to you will work...

If you will pass the checkbox data into another form... then you can  put in a hidden field... Using split fucntion you can seperate the data...

Now when you process the data on the 3rd form you will again put it in a hidden field to again manipulate the data using split function just like I had mention...

I wish I could have more time to spare but I got to go... need to sleep...

Hope this help...

Happy programming...

Right I now have the following and session variables are getting set for each checkbox in the form.

'Region Association rules 1
session("RegionAssociation") = request.form("RegionAssociation")
arrayRegions  = split(session("RegionAssociation"), ", ")
for i=Lbound(arrayRegions) to Ubound(arrayRegions)
session("Region"&i) = arrayRegions(i)
next

What will the session variables be called on another page???
How do I reference them, I'm abit confusedas to what the names fo the session variables will be. :(

Will the session variables be called Session("Region1") - Session("Region14") say?

I cant get my head round this what so ever. lol

Stick with my original solution and kblacks amendment

Place this on pages 2 and 3
for each x in request.form
   if left(x,4)="chk_" then
      Response.Write "<input name='" & X & "' value = '" & request(x) & "'>"
   end if
next

Then on the final page where you do whatever with the variables you just use an amendment of the code

for each x in request.form
   if left(x,4)="chk_" then
      ' What do you want to do now with all the variables.
   end if
next

Let me amend the page 2 code, we forgot to make them hidden:

or each x in request.form
   if left(x,4)="chk_" then
      Response.Write "<input name='" & X & "' value = '" & request(x) & "' type='hidden'>"
   end if
next

SimonWGoldsmith,

Below are three fiel to simulate my approach...
just cut ans paste

=======save this as SimonWGoldsmith-1.asp
<%
'Since the data  is comming form the db
' I will just create an array for the data to be out in the check box

teststr = "checkbox1,checkbox2,checkbox3,checkbox4,checkbox5,checkbox6,checkbox7,checkbox8,checkbox9,checkbox10,checkbox11,checkbox12"

%>

<form name="form1" method="post" action="SimonWGoldsmith-2.asp">
  <table width="75%" border="0">
    <tr>
      <td>Select</td>
      <td> Description</td>
    </tr>
    <%
  arrayteststr = split(teststr,",")
 
  for i = Lbound(arrayteststr) to Ubound(arrayteststr)
 
  %>
    <tr>
      <td><input name="chkbox" type="checkbox" value="<%=arrayteststr(i)%>"></td>
      <td><%=arrayteststr(i)%></td>
    </tr>
    <%next%>
    <tr>
      <td colspan="2"><input type="submit" name="Submit" value="Submit"></td>
    </tr>
  </table>
</form>


========save this as SimonWGoldsmith-2.asp

<%session("chkbox") = request.form("chkbox")%>

<form name="form1" method="post" action="SimonWGoldsmith-3.asp">
<input name="chkbox" type="hidden" value="<%=request.form("chkbox")%>">
Below is the output using the request("chckbox")
1. using the .count property
  <table width="75%" border="0">
    <tr>
      <td>Select checkbox</td>
    </tr>
    <%  
  for i = 1 to request.form("chkbox").count
 
  %>
    <tr>
      <td><%=request.form("chkbox")(i)%></td>
    </tr>
    <%next%>
  </table>
  <br>
  <br>
  2. using the request collection and gettin the elemname
  <table width="75%" border="0">
    <tr>
      <td>Select checkbox</td>
    </tr>
    <%  
  for each elem in request.form("chkbox")
 
  %>
    <tr>
      <td><%=elem%></td>
    </tr>
    <%next%>
  </table>
  <br>
  <br>
  3. using the session
 
 
  <table width="75%" border="0">
    <tr>
      <td>Select checkbox</td>
    </tr>
    <%  
      arraysession = split(session("chkbox"),",")
  for i = Lbound(arraysession) to Ubound(arraysession)
 
  %>
    <tr>
      <td><%=arraysession(i)%></td>
    </tr>
    <%next%>
  </table>
  <br>
  <br>
    <tr>
      <td><input type="submit" name="Submit" value="Submit"></td>
    </tr>
</form>


=======SimonWGoldsmith-3.asp

<%
if request.form("test") <> "" then

response.write "Below are the selected checkbox using session <br>"

      arraysession = split(session("chkbox"),",")
  for i = Lbound(arraysession) to Ubound(arraysession)
 
  response.write arraysession(i) & "<br>"
      
  next

response.write "Below are the selected checkbox using hidden field <br>"

      arrayhidden = split(request.form("chkbox"),",")
  for i = Lbound(arrayhidden) to Ubound(arrayhidden)
 
  response.write arrayhidden(i) & "<br>"
      
  next

else

response.write "Please input a char on the textbox to see the output"

end if
%>
<br><br>

if you will use rin another form then you will just the name of the hidden field...

Since the hidden field is comma delimited as well as the session..<br>

You can use split which is used on the third solution...<br>

But if you still need to pass it on a form just put agin it in a hidden field...

<form name="form1" method="post" action="SimonWGoldsmith-3.asp">
<input name="chkbox" type="hidden" value="<%=request.form("chkbox")%>">
  <table width="75%" border="0">
    <tr>
      <td>Name</td>
      <td><input name="test" type="text"></td>
    </tr>
      <td colspan="2"><input type="submit" name="Submit" value="Submit"></td>
    </tr>
  </table>
</form>
