User refer url

[kingnath]

I don't get the implementation well, and having issue with the form.

This is what i did;

on join.php

<pre>

Code:

$ref = Input::get('refid');
$name = $db->query("SELECT username FROM users WHERE id = ?",array($ref))->first();

</pre>


and on _join.php

<pre>

Code:

<label for="refer">Refer by* (If no referee enter "Semilore")</label>
        <input  class="form-control" type="text" name="refer" id="refer" placeholder="Enter Referee Username" value="<?php if (!$form_valid && !empty($_POST)){ echo $refer;} ?>" required >

</pre>


i don't understand this line

Code:

<?=$name-/>username>”></p>            </div><!-- .bbp-reply-content --></div><!-- .reply -->                        </li><!-- .bbp-body -->    <li class=
