How do I get the value of gender radio button (male, female) with CodeIgniter?
提问by user1822263
I got this in my view.
我在我看来是这样的。
<input type="radio" name="male" value="0">Male</input>
<input type="radio" name="female" value="1">Female</input>
What do I have to do to get any of these values? I need it to send them later to the database, so I have to get 0 or 1 to fill that field.
我该怎么做才能获得这些值中的任何一个？我需要它稍后将它们发送到数据库，所以我必须得到 0 或 1 来填充该字段。

Since the name of your input are separate, it won't really function as radio buttons. Try changing the name to something like "gender" and add appropriate values to it. It can be 0 for male, 1 for female, or just the term male and female. I used the latter for the example below. The controller section uses a form_validation library, which should be very useful when dealing with forms.
由于您输入的名称是独立的，因此它不会真正用作单选按钮。尝试将名称更改为“性别”之类的名称并为其添加适当的值。它可以是 0 代表男性，1 代表女性，或者只是男性和女性这个词。我在下面的例子中使用了后者。控制器部分使用了一个 form_validation 库，它在处理表单时应该非常有用。
View:
看法：
<input type="radio" name="gender" value="male">Male</input>
<input type="radio" name="gender" value="female">Female</input>
Controller:
控制器：
$this->load->library('form_validation');
$this->form_validation->set_rules('gender', 'Gender', 'required'); // This will check if gender is selected.
if ($this->form_validation->run()) {
$gender = $this->input->post('gender'); // This will contain "male" or "female"
}
else {
$error = validation_errors();
}

Make the names of both radio buttons the same. Example gender. In your controller do $this->input->post('gender');to get the value
使两个单选按钮的名称相同。例子gender。在您的控制器中执行$this->input->post('gender');以获取值
