Pre-Selection of a Radio button

Question

I am using forms in html there are some radio buttons in it too, when the form is incomplete and user press submit button, server redirects(using header) the user to the form again and says to fill the for completely, when the user came back to the page the data he had already filled it should have been there, i have done this in case of name and email but it is difficult in case of radio buttons

header("location:main.php?nm=$name&email=$em&gender=$gen&paf=$paf&msg=please fill form");

form code

Gender: <input type="radio" name="gender" value="Male" >Male <input type="radio" name="gender" value="Female" >Female <input type="radio" name="gender" value="Other" >Other

You can use checked property

<input type="radio" name="name" value="" checked="checked" />

on the form page in php code u have to set variables of $male, $female to checked like this.

if (!empty($_GET['gender'])){
if($_GET['gender']=="Male"){
    $male="checked";
}
else if($_GET['gender']=="Female"){
    $fmale="checked";
}
else{
    $other="checked";
}}

and in the form echo those variables

    Gender:
  <input type="radio" name="gender" value="Male" <?php echo $male; ?>>Male
  <input type="radio" name="gender" value="Female" <?php echo $fmale; ?> >Female
  <input type="radio" name="gender" value="Other" <?php echo $other; ?> >Other
