HTML url passing multiple parameters - html

Question

I'm trying to pass multiple parameters with an url. I have checked out almost every topic about it, but can't seem to find an answer. I have tried different ways, but it still doesn't work.
It is only sending the first parameter.
If I start with post_id - I can't get comment_id
If I start with comment_id - I can' get post_id
My idea of url:
http://localhost/index.php?post_id=3&comment_id=6
OR
http://localhost/index.php?post_id=3&comment_id=6
I try to use it later like this:
else if(isset($_GET['post_id']) & isset($_GET['comment_id'])){
$post_id = $_GET['post_id'];
$comment_id = $_GET['comment_id'];
$user_id = $this->UserModel->getUser();
$BlogPost = $this->BlogModel->getBlogPost($post_id);
$BlogComments = $this->BlogModel->getBlogCommentList($post_id);
$BlogComments = $this->BlogModel->deleteBlogComment($comment_id,$user_id);
include 'views/ViewBlogPost.php';
}

Your below URL Structure is perfactly true
http://localhost/index.php?post_id=3&comment_id=6
Logic to Pass data Through URL in your script is called as QueryString Which you can build in below way
NAME=VALUE - this is called Name Value Pair , you can Pass Multiple Name Value pair by appending with '&' only
e.g.
http://localhost/index.php?name_1=value_1&name_2=value_2
on server side you will retrive them by using GLOBAL $_GET e.g print_r($_GET); to view all the passed data.
individually you can access them by using
echo $_GET['name_1']; echo $_GET['name_2'];
Also i suggest you to check your GPSC setting in your php.ini to define the priorities between your Super Globals.
