Hi i have a from with few radio buttons to filter my data...I want to check url to make a radio button checked...How i can achieve that ??

Form:

<form method="post">
<div>
    <input id="radio2" type="radio" name="scat" value="ABC" data-href="example.com?link=[value]">

    <label for="radio2">ABC</label>
