better to pass the value in the hidden field
最好传递隐藏字段中的值
<form class="addinvestmentform" action="<?php echo base_url();?>index.php/ctl_dbcont/input_investment" name="application" method="post" >
<input type="hidden" name="my_id" value="<?php echo $id; ?>"/>
</form>
in your ci function
在你的 ci 函数中
function input_investment() {
$id = $this->input->post('my_id');
$this->load->helper('form');
$this->load->helper('html');
$this->load->model('mod_user');
$this->mod_user->insertinvestment($id);
}
or if you want (A test)
或者如果你想要（测试）
// Sample view
// 示例视图
<?php $id = 1; ?>
<form action="<?php echo base_url('my_class/my_method/' . $id); ?>" method="post" >
<input type="submit" />
</form>
// Controller
// 控制器
class My_class extends CI_Controller {
public function index() {
$this->load->view('my_class');
}
public function my_method($id) {
echo $id; // outputs 1
}
}

You need to use PHP and echo $id in the element if you want the value, right now you're sending '$id' to input_investment($id).
如果您想要该值，您需要使用 PHP 并在元素中回显 $id，现在您正在将 '$id' 发送到 input_investment($id)。
<form class="addinvestmentform" action="<?php echo base_url();?>index.php/ctl_dbcont/input_investment/<?php echo $id; ?>" name="application" method="post" >
//some code
</form>

Here your form method is post so you cont get the id through the get method ,you can do like
在这里，您的表单方法已发布，因此您可以通过 get 方法继续获取 id，您可以这样做
<form class="addinvestmentform" action="<?php echo base_url();?>index.php/ctl_dbcont/input_investment" name="application" method="post" >
<input type="hidden" name='id' value="<?php echo $id;?>">
</form>
and in your controller you can try with post like
在你的控制器中，你可以尝试像这样的帖子
$id = $_POST['id'];
or
或者
$id = $this->input->post('id');
it willl better option for you in all cases if you are trying to send single or multiple data to the controller from an form....
如果您尝试从表单向控制器发送单个或多个数据，那么在所有情况下它都会为您提供更好的选择....

$route['ctl_dbcont/input_investment/(:num)'] = "ctl_dbcont/input_investment/";
Just add this line at your config/route :) .
只需在您的 config/route 中添加这一行 :) 。
This will work with numbers only, if you have other type of IDs you can use (:any)
这仅适用于数字，如果您有其他类型的 ID，则可以使用 (:any)
Other option is to catch the id directly using :
其他选项是直接使用：
$id = $this->uri->segment(3);
Where segment(3) is the third element after your domain :
其中 segment(3) 是域之后的第三个元素：
http://domain/segment1/segment2/segment3
