通过 Python 将多选框数据传递至 CGI 程序


在需要选择多个选项时,会使用多选框。

示例

以下是包含两个多选框的表单的 HTML 代码示例 −

<form action = "/cgi-bin/checkbox.cgi" method = "POST" target = "_blank">
<input type = "checkbox" name = "maths" value = "on" /> Maths
<input type = "checkbox" name = "physics" value = "on" /> Physics
<input type = "submit" value = "Select Subject" />
</form>

输出

此代码的结果为以下表单 −

以下是用来处理网页浏览器给予的多选框按钮输入的 checkbox.cgi 脚本。

#!/usr/bin/python
# Import modules for CGI handling
import cgi, cgitb
# Create instance of FieldStorage
form = cgi.FieldStorage()
# Get data from fields
if form.getvalue('maths'):
   math_flag = "ON"
else:
   math_flag = "OFF"
if form.getvalue('physics'):
   physics_flag = "ON"
else:
   physics_flag = "OFF"
print "Content-type:text/html\r\n\r\n"
print "<html>"
print "<head>"
print "<title>Checkbox - Third CGI Program</title>"
print "</head>"
print "<body>"
print "<h2> CheckBox Maths is : %s</h2>" % math_flag
print "<h2> CheckBox Physics is : %s</h2>" % physics_flag
print "</body>"
print "</html>"
