PHP: Isset with if else statement
<p><strong>iso.obj.php</strong></p>

<pre><code>$from = null;
$too = null;

if (isset($_POST['search'])) {
    if ($from = null) {
        $from = date("Y-m-d");
    } else {
        $from = $_POST['FromDateTime'];
    }

    if ($too = null) {
        $too = date('Y-m-d', strtotime("+30 days")) . " 23:59:59"; 
    } else {
        $too = $_POST['ToDateTime']." 23:59:59";
    }
}
$sql ="//statement here with
WHERE capDateTime &gt;='{$from}' AND capDateTime &lt;='{$too}'";
</code></pre>

<p>The code is working fine but i got problem when person request the page and its return an empty table. But if i select date and time manualy its will display according to the date and time.  </p>

<p>My question is: How do i put current date if not set and if set follow the $_POST?</p>
