[英]How do I get selected value from drop down box in Perl CGI
I am populating the drop down menu from database. 我正在从数据库填充下拉菜单。 And when I submit the form I am getting empty string in selected option.
当我提交表格时,我在选择的选项中得到空字符串。 Here's my code any help will be appreciated.
这是我的代码,任何帮助将不胜感激。 I have selected the first option as default any help.
我选择了第一个选项作为默认的任何帮助。
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>";
I am getting the value using below but its returning empty whatever I select. 我正在使用下面的值,但无论我选择什么,它都返回空。
my $Name = param('name');
You are missing name="client_name"
in the select tag. 您在选择标记中缺少
name="client_name"
。
You probably ought to be escaping the client name in the value attribute (though for United Dynacare it isn't necessary). 您可能应该在value属性中转义客户名称(尽管对于United Dynacare没有必要)。 Using a library to generate your HTML (for instance,
CGI
) would have helped with both of these things. 使用库来生成您的HTML(例如
CGI
)将对这两个方面都有帮助。
