Registration form - Checking if data entered ($_SERVER['PHP_SELFf'])
<p>What I want to do is,</p>

<ol>
<li>User comes to registration form.</li>
<li>Fills it , press enter, registration goes on.</li>
<li>If he doesnt fill it, echo Data Missing.</li>
</ol>

<p>Where I am stuck,</p>

<ol>
<li>Using isset, it echos Data Missing at the first visit itself which shouldnt happen.</li>
</ol>

<p>Any suggestions? </p>

<p>I am not looking for any codes as  I want to learn it up myself. Just the idea would do.</p>
