Using Variables, and
Forms in Active Server Pages
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 create the
form, and then you 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
<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
<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'll 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. You may need to create a variable.
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 catīs name is <% =TheName %>. Do you want to see <% =TheName
%>?. |
