从Codeigniter URL抓取参数数据

Question

I am working on a CI project and have a need to send data to a controller as a url parameter. I am used to doing something like this.

<a href="site/controller/function?id=1">

Then I am able to grab the parameter using $_GET.

However I was told to use this method.

<a href="site/controller/function/1">

I did this and it shows up in the url when I click on the link, but I have no idea how to grab the actual parameter.

Any advice?

Answer 1

I figured it out, I used the following.

$id=$this->uri->segment(3);

And this got me the id number I passed.

Answer 2

You better should use like below in your codeIgniter function. Even though your code also fine.

function funcName ($param1)
{
 echo $param1;
}
