如何将pagination的get参数添加到url的末尾？

Question

I'm using pagination and also advantage search options in a page.

Search is working great. For example, when I use the search, url is like this:

http://example.com/category/contents?**title=test&year=2015&author=test**

It's okay. But when I use the pagination links, all search parameters are gone..

http://example.com/category/contents?**page=3**

How can I solve this?

I want to do this:

http://example.com/category/contents?title=test&year=2015&author=test&**page=3**

EDIT: Okay, I'm using like that now:

$parameters = "";

if(isset($_GET["x_param"])){
    $parameters .= "&parametername=".$_GET["x_param"]    
}

And I'm adding the $parameters variable to the end of pagination links.

?page=xx".$parameters

Store the required values from URL in variables like follow.

$title="";

if(isset($_GET["name"])) {
   $title=$_GET["title"];
}

In above code we're saving value of title parameter in $title variable if it is set. You can do the same for other values.

Now pass this values when you're hitting the next or previous page along with page number.
