How do i Dim dynamic information? - ASP / Active Server Pages

PLEASE forgive me! I have been a web designer for a few years now, and want to move on and learn a programming language.

Im currently building a website, and i have a js file that contains some info relating to a directory of taxis in the UK.

Copy pasting is getting boring now, so i wanted to automate and simplify the procedure so i can ask a few friends to contribute to the process (i couldnt ask my friends to open up a js file and expect them to understand it)

I have had very limited asp/vb experience, i can 'reverse engineer and tweak' scripts of asp/vb that the company i obtain my CMS from has written, but *creating* something is totally new to me.

First of all i wanted some input boxes that can POST info to a results page, but then i realised on one particular piece of info, i would need 20 input boxes. so i thought i would explore the loop aspect (aspect - the right phrase there?) so i didnt have to code 20 input boxes with different names etc. so i made a loop that creates:

District 1 : INPUTBOX (named d1)
District 2 : INPUTBOX (named d2)
District 3 : INPUTBOX (named d3)

and so on up to 20

It worked! Great ! But then i realised i had to dim them. And this is where i am really stuck.

Could someone please look over my code and offer a few directions i should be looking in? It would be much appreciated.

As it stands, the countyname and districts 1 & 2 are dim'd manually - so they actually provide a successful output, but i am looking for a way to write that dim line i have there and have it dim d1 thru to d20 dynamically.

Here is what i have:

Expand|Select|Wrap|Line Numbers

 
<html>

<body>

Start a New County<br />

-------------------------

<form action="messabout.asp" method="post">

County Name: <input type="text" name="countyname" size="40" /><br />
 
<%

    for i=1 to 20

    response.Write("District " & i & ":  <input type=""text"" name=""d" & i & """ size=""40"" /><br />" & vbcrlf & "")

    next
 
%>
 
<input type="submit" value="Submit" />

</form>
 
<%

// i need to know how to write this dim line with out manually writing d1,d2 thru to d20 - i created the input boxes fine, all with dx incrementing nicely, but this fails me

dim countyname, d1, d2

countyname=Request.form("countyname")

d1=Request.form("d1")

d2=Request.form("d2")

If countyname<>"" Then

      Response.Write("The County you created was: " & countyname & " <br />The first line is added to the main county list. The rest is the county itself<p>")

      Response.Write("This is the code to add the county to config.js:<p><textarea rows=20 cols=100>addList(&quot;First-Select&quot;, &quot;" & countyname & "&quot;, &quot;&quot;, &quot;" & countyname & "&quot;); " & vbCrLf & vbCrLf &"///////////    " & countyname & "    ///////////" & vbCrLf & vbCrLf &"addOption(&quot;" & countyname & "&quot;, &quot;Select a District --&quot;, &quot;&quot;, 1); //HEADER OPTION" & vbCrLf &"addList(&quot;" & countyname & "&quot;, &quot;" & d1 & "&quot;, &quot;&quot;, &quot;" & d1 & "&quot;);" & vbCrLf &"")

End If
 
If d2<>"" Then

    response.Write("addList(&quot;" & countyname & "&quot;, &quot;" & d2 & "&quot;, &quot;&quot;, &quot;" & d2 & "&quot;);" & vbCrLf &"")

    End if

%>
 
<% response.write("</textarea></p>") %>
 
</body>

Hi Patrick,

The short answer is 'You can't' - you just have to declare them all in a list.

However you could store the values that you are capturing in an array which might make your life a bit easier. Have you had any experience using arrays? Here's an example:

Expand|Select|Wrap|Line Numbers

 Dim d(20)

For i = 1 to 20

     d(i) = Request("d" & i)

Loop

Let me know if this helps,

Dr B - thank you for that!

I guess even though you answered 'you cant' - you then gave me the method to do it!

I havent looked into arrays - what other uses do they have?

Any way, since i posted my orginal thread, i decided to explore another method.

Writing the form data to a text file.

This is what i have to achieve this:

Expand|Select|Wrap|Line Numbers

 
<%

Dim countyname

Dim districtname

countyname = request.Form("countyname")

districtname = request.Form("districtname")

%>
 
<html>

<head>

<title>Form for Taxi Directory</title>

</head>

<body>
 
<form name="taxi" method="post" action="mess.asp?countyname=<% request.Form("countyname") %>">

County Name: <input name="countyname" type="text">

District Name: <input name="districtname" type="text">

<input type="submit" value="submit">

</form>
 
<%
 
Dim fso

Dim tst
 
Set fso=Server.CreateObject("Scripting.FileSystemObject")

Set tst=fso.OpenTextFile ("C:\Domains\mysite.co.uk\wwwroot\countys.txt", 8, true)

response.Write("<p>Note - Will probably never need this line, but here it is anyway:</p>addList(&quot;First-Select&quot;, &quot;" & request.Form("countyname") & "&quot;, &quot;&quot;, &quot;" & request.Form("countyname") & "&quot;);")

response.Write("<a href=""countys.txt""><h4>*CHECK TO SEE WRITTEN FILE</a> * YOU WILL HAVE TO REFRESH THE TEXT FILE TO SEE FRESH DATA</h4>")
 
if request.Form("countyname")<>"" Then

tst.writeline ""

tst.writeline "///////////    " & request.Form("countyname") & "    ///////////"

tst.writeline ""

tst.writeline "addOption(""" & request.Form("countyname") & """, ""Select a District --"", """", 1); //HEADER OPTION"

end if
 
if request.Form("districtname")<>"" then

tst.writeline "addList(""" & request.Form("countyname") & """, """ & request.Form("districtname") & """, """", """ & request.Form("districtname") & """);"

end if
 
response.Write("<h3>Info that was written:</h3>")

response.Write("County Name: ") 

response.Write request.Form("countyname")

response.Write("<br />District Name: ") 

response.Write request.Form("districtname")
 
tst.close

Set tst = Nothing

Set fso = Nothing
 
%>
 
</body>

</html>

But i run into a problem....

On first page load, i enter the county and the first district, hit submit. I can then view the file it created and wrote to.

At that point, i just need to enter a few more districts, but the countyname HAS to be in the output - and that variable is not carried/passed on past that first submit.

I have tried GET and POST - thinking that at least with GET i could grab data off the URL, but no joy. I automatically assumed that becuase the page posts results to itself - thet variables would still be 'in memory' and available to call upon.

This method is better for what i want to simpify (easier data entry in a format that is used in a js file) - and success will shave weeks off of the company listings i have to input from 80 counties x 6(average) districts per county x 5 listings per districts.......

I really need to know how/why to make that countyname variable stay constant.

Big thanks,

Patrick Shelley

I have been thinking on this -

If i could make the countyname input box retain its value after the form has been submitted - all would be fine. How would i achieve this?

Many thanks,

Hi Patrick,

To retain the value of an input across form submits you can do the following:

Expand|Select|Wrap|Line Numbers

<input name="countyname" type="text" value="<%=Request("countyname")%>">

This will set the value of the textbox to the submitted value.
