Forms are a convenient way to communicate with visitors to your Web
site. Using forms, you can create a survey form and ask visitors to fill
it out. When they fill out the form, you can process the results automatically.
With forms, there are two steps: first you need to create
the form, and then you need process it.
To create a form for an Active Server Page, just create a standard
HTML form.
To try out this example, create an HTML file ("form_response.html")
and cut-and-paste the following text into it.
form_response.html try !
<
Code :-
<html>
<head><title>Asking for information</title></head>
<body>
<form method="post" action="form_response.asp">
Your name: <input type="text" name="name" size="20"><BR>
Your email: <input type="password" name="email"
size="15"><BR>
<input type="Submit" value="Submit">
</form>
</body>
</html>
|
Active Server Pages provide a mechanism for processing forms that,
unlike CGI scripting, doesn't involve serious programming: the Request.Form.
Considering the form above, we may create the file bellow and get
a response.
form_response.asp try !
<
Code :-
<html>
<head><title>Responding to a form</title></head>
<body>
Your name is <% =Request.Form("name") %> <BR>
Your email is <% =Request.Form("email") %>
</body>
</html>
|
To display the contents of each field in the form, type:
| <% =Request.Form(fieldname)
%> |
where fieldname is the name of the field.
CREATING A VARIABLE:
You probably want to do more with your forms than display their contents
in a Web page.
For example, based on the contents of the form, you may want
to create a variable and insert that variable in different places of your
response page.
For this you need to create a vraible and to do that, just make up a name
and set it equal to the contents of the field.
For example, if you have a field called "CatName"
in your form, you can save it into a variable called "TheName"
by typing:
">
| <% TheName = Request.Form("CatName")
%> |
If you want to display "VisitorName" several times within
a text you only need to include the variable in the text. For example:
My cat´s name is <% =TheName %>. Do you want to see <%
=TheName %>?.
EXAMPLE:
The form in this example asks users to introduce their names and their
favorite color: red, blue, or green. When the form is received, the server
responds displaying these data.
nameandcolor.html try !
Code :-
<html>
<head><title>Name and Color</title></head>
<body>
<FORM ACTION="nameandcolor.asp" METHOD=POST>
Let me know your Name and Favorite Color:
<P>YOUR NAME:
<INPUT TYPE="TEXT" NAME="YOURNAME" SIZE=20>
<P>COLOR:
<INPUT TYPE="RADIO" NAME="COLOR" VALUE="1"
CHECKED>Red
<INPUT TYPE="RADIO" NAME="COLOR" VALUE="2">Green
<INPUT TYPE="RADIO" NAME="COLOR" VALUE="3">Blue
<P>
<INPUT TYPE="SUBMIT" VALUE="OK">
</FORM>
</body>
</html> |
Now, create an ASP file ("nameandcolor.asp") and cut-and-paste
the following text into it.
nameandcolor.asp try !
Code :-
<html> <head><title>Name and Color</title></head>
<body>
<% TheName = Request.Form("YOURNAME") %>
<% colornumber = Request.Form("COLOR") %>
Hi, <% =Thename %>.<BR>
I know your favorite color is
<% if colornumber = "1" then %>
red
<% end if %>
<% if colornumber = "2" then %>
green
<% end if %>
<% if colornumber = "3" then %>
blue
<% end if %>.
</body>
</html> |
