如何从Perl CGI的下拉框中获取选定的值 [英] How do I get selected value from drop down box in Perl CGI

问题描述

我正在填充数据库的下拉菜单。当我提交表单时，我在选定的选项中获得了空字符串。这里是我的代码任何帮助将不胜感激。

I am populating the drop down menu from database. And when I submit the form I am getting empty string in selected option. Here's my code any help will be appreciated. I have selected the first option as default any help.

print "<br>Name: <select>";
while ( my ($name) = fetchrow_array() ) {
    if ($name eq "Somethinge") {
        print "<option value=\"$name\" selected>" . $name . "</option>\n";
    }else {
        print "<option value=\"$name\">" . $name . "</option>\n";
        }
}
print "</select>";

我正在使用下面的值，但是它会返回空的值。

I am getting the value using below but its returning empty whatever I select.

my $Name = param('name');

推荐答案

您缺少 name = client_name在选择标记中。

您可能应该在value属性中转义客户端名称（尽管对于United Dynacare而言，它不是没有必要）。使用库来生成HTML（例如， CGI ）会对这两件事情有所帮助。

You probably ought to be escaping the client name in the value attribute (though for United Dynacare it isn't necessary). Using a library to generate your HTML (for instance, CGI) would have helped with both of these things.
