Can I use $_POST & $_GET at the same time?
<p>I have a following form:</p>

<pre><code>&lt;form action="doThis.php?warehouse=12" method="post"&gt;
  &lt;input name="field1" type="text" /&gt;
  &lt;input name="field2" type="text" /&gt;
&lt;/form&gt;
</code></pre>

<p>And <code>doThis.php</code>:</p>

<pre><code>$field1 = mysql_real_escape_string($_POST['field1'], $mysql);
$field2 = mysql_real_escape_string($_POST['field2'], $mysql);

$warehouse = $_GET['warehouse'];
if ( !someTableNameValidation($warehouse) ) {
    someErrorHandling();
}
$qry = "INSERT INTO table".$warehouse." ( field1, field2 ) VALUES( '$field2', '$field2') ";
$result = @mysql_query($qry, $mysql);
</code></pre>

<p>As you can see, I'm using $_POST to get data from the form, and $_GET to get variable <code>$warehouse</code> which is used to indicate table number.</p>

<p><strong>Can I use both $_POST &amp; $_GET at the same time? Is this kind of usage correct?</strong></p>
