How can I add/update recordset based on dynamic posted input fields? [duplicate] - asp-classic

Question

on submit of a form, I would like to capture the field names and values of the forms and I want them passed without even showing in the browser (Response.Write makes them visible in the browser). How I can do this please? I am using this code:
For Each Item In Request.Form
fieldName = Item
fieldValue = Request.Form(Item)
Response.Write(""& fieldName &" = Request.Form("""& fieldName &""")")
Next

Answer 1

Your code is essentially correct, so just remove the Response.Write and do something else with the fieldName and fieldValue variables you're populating. After you're done with manipulating the data (either inserting it into a database or sending an e-mail), you can redirect the user to a success / thank you page.
To test that you're receiving the correct input, you can change your Response.Write to
Response.Write fieldName & " = " & fieldValue & "<br>"
Update
Here's how you could use a Dictionary Object to put your field names and field values together:
Dim Item, fieldName, fieldValue
Dim a, b, c, d
Set d = Server.CreateObject("Scripting.Dictionary")
For Each Item In Request.Form
fieldName = Item
fieldValue = Request.Form(Item)
d.Add fieldName, fieldValue
Next
' Rest of the code is for going through the Dictionary
a = d.Keys ' Field names '
b = d.Items ' Field values '
For c = 0 To d.Count - 1
Response.Write a(c) & " = " & b(c)
Response.Write "<br>"
Next

Answer 2

This is a very small snippet I use to show all form fields POSTED
<%
For x = 1 to Request.Form.Count
Response.Write x & ": " _
& Request.Form.Key(x) & "=" & Request.Form.Item(x) & "<BR>"
Next
%>

To complement the answer, and reply to the second question #ReneZammit asked in his comment from Jan 31, 2012 at 10:17, Creating "dynamic" ASP/VBScript variables based on the field names IS POSSIBLE!
You just have to use the "magical" Execute() function :
<%
'If the form was SUBMITTED
If (Request.Form("submitForm") = "1") then
Dim fieldName
Dim fieldValue
'Loop through all the form items
For Each Item In Request.Form
'Get Form item properties
fieldName = Item
fieldValue = Request.Form(Item)
'Use Execute() to interpret dynamically created ASP code
Execute("Dim myVar_" & fieldName)
Execute("myVar_" & fieldName & " = """ & fieldValue & """")
Next
'Use your new Dynamic variables Names, that are now REAL native variables names!
Response.Write "<br>myVar_banana = " & myVar_banana
Response.Write "<br>myVar_pear = " & myVar_pear
Response.Write "<br>myVar_tomato = " & myVar_tomato
'If the form have to be DISPLAYED
else
%>
<form method="post">
<input type="text" name="banana" value="This is Yellow">
<br>
<input type="text" name="pear" value="This may be Green">
<br>
<input type="text" name="tomato" value="This should be Red">
<input type="hidden" name="submitForm" value="1">
<input type="submit">
</form>
<%
end if
%>
