Below is my code:

index.php file

javascript of index.php file

```
function Result()
{
  var marks = 55;
  document.getElementById("hdnmarks").innerHTML= marks; 
  window.location = "results.php";
}

```

HTML of index.php

```
<input type="hidden" name="hdnmarks" id="hdnmarks">

```

**Description:** I have a web page with url `localhost/index.php`. In index.php, I have a submit button on the click of which I call `Result` javascript method which sets the marks = 55 and put it into the hidden field and takes me to the `results.php` page.

In `results.php`, I have to insert value of marks in the database. But how should I access the marks as those were stored in the hidden field of `index.php` file?

I want to put marks in the session, but how should I maintain the PHP session in javascript function? I mean where and when should I put marks in the session before moving to `results.php`?
