未定义的子程序CGI :: radio [英] Undefined subroutine CGI::radio

问题描述

我有一个有关学生数据的应用程序，并且我正在尝试建立一个广播电台组，其中提供有关学生性别的选项。但是它向我显示了以下错误：C：/wamp/bin/apache/apache2.2.22/cgi-bin/modify.pl第196行未定义的子例程CGI :: radio

I have an application about a student data,and i am trying to make a radio-group which has options about gender of the student. But it shows me the following error: Undefined subroutine CGI::radio at C:/wamp/bin/apache/apache2.2.22/cgi-bin/modify.pl line 196

   $cInput .= $q->div({-class => 'control-group'},
                    $q->label({-class => 'control-label', -for => 'gender'}, "Gender:"), 
                    $q->div({class => 'controls'}, 
                    $q->span({class => 'span12'},
                    $q->label({-class => 'blue'},
                    $q->radio-group({-id => 'gender', -name => 'gender', -values => ['M','F'],-labels => \%labels, -default => $cGender, 'true'})))));  

可能是什么问题？

推荐答案

您正尝试呼叫 $ q->广播组，但是：

1. -被视为减法运算符


2. 该方法称为 radio_group （带下划线）

1. The - is being treated as a subtraction operator
2. The method is called radio_group (with an underscore)
