Let's say that you have code that will hold what you want to display in a variable, like this:

$username = 'Mark';

And then, you need to display it in an input box, you would do this:

<input type="text" value="<?php echo $username; ?>">

So, in your code, instead of this line:

echo $row['yname'];     

you would set a variable (instead of outputting it right on the screen)

$yname = $row['yname']; 

Then, later on, in your input field:

 <input type="text" class="form-control" placeholder="Your Name" value="<?php echo $yname; ?>" required name="yname" id="yname" autofocus >

Do you currently have the HTML and PHP parts in different scripts? If so, they'll need to be merged so you can use the PHP variables in form as mogosselin suggested. Your code might look something like the following:

$query = mysql_query("SELECT yname,mail,tp FROM reg WHERE mail = '$mail' LIMIT 1");
$row = mysql_fetch_assoc($query);
<form class="form-signin" role="form" id="form1" action="post_user.php">
    <label>Name <input type="text" class="form-control" placeholder="Your Name"<?php if($row['yname'] != '') { echo ' value="' . $row['yname'] . '"'; } ?> required name="yname" id="yname" autofocus /></label><br />
Note that I added the LIMIT clause to the query since you're probably only looking for one result. If that's a correct assumption, you don't need the loop. I also modified the <label> tag so that it's attached to the corresponding input field.
