After refresh the page, the user selected radio button is missing.
How can I always display the user's "selected radio button" even I had refresh the page?

<input name="radiobutton" type="radio" value="" id="all" checked />

radio with checked is not suitable, because it will always display the default radio button.

Below is my code:-

<form name="myfrm" id="myfrm" action="" method="post">

    <input name="radiobutton" type="radio" value="" id="all" />

    <label>All Languages</label>

    <input name="radiobutton" type="radio" value="" id="english" />

    <label>English</label>

</form>

You should conform to standards and give a value to every attribute. That means you need checked=checked

<input name=radiobutton type=radio value= id=all checked=checked />

And in case you were asking how to stick to what was selected previously: AFAIK, it is not possible with plain HTML. You need to bind a Javascript event that submits the selected radio button to your server and a dynamically generated page (by PHP, Python, whatever) that puts the 'checked=checked to the radio button that was submitted as checked.

EDIT:

As I see it, submitting the currently selected radio button to the server and generating your page dynamically might be overkill.
