Reading User Input (for Example 3)
To send information from the browser
to a CGI program, we need to construct
a form as follows:
<HTML>
<HEAD>
<TITLE>Sample form for Example 3</TITLE>
</HEAD>
<BODY>
<FORM>
</FORM>
</BODY>
</HTML>
|
|
|
In the form area, we specify the necessary fields.
For example:
<HTML>
<HEAD>
<TITLE>Sample form for Example 3</TITLE>
</HEAD>
<BODY>
<FORM>
Name: <INPUT TYPE="TEXT" NAME="NAME"> <BR>
Student ID #: <INPUT TYPE="TEXT" NAME="STUDENT_ID_NUM"> <BR>
<P>
<INPUT TYPE="SUBMIT" VALUE="OK">
</FORM>
</BODY>
</HTML>
|
|
|
There are two methods for sending
information from a browser form to
a CGI program:
- GET - pass information through
QUERY_STRING environment variable
- POST - pass information through
STDIN
We specify the method and the program which
will process the input fields in the <FORM>
tag fields:
<HTML>
<HEAD>
<TITLE>Sample form for Example 3</TITLE>
</HEAD>
<BODY>
<FORM METHOD="GET" ACTION="/cgi-bin/cai_pnk/disp_log.cgi">
Name: <INPUT TYPE="TEXT" NAME="NAME"> <BR>
Student ID #: <INPUT TYPE="TEXT" NAME="STUDENT_ID_NUM"> <BR>
<P>
<INPUT TYPE="SUBMIT" VALUE="OK">
</FORM>
</BODY>
</HTML>
