<p>I'm getting an error <strong>Warning: implode() [function.implode]: Invalid arguments passed in /home/social/public_html/form_test.php on line 13</strong> I'm not sure why i'm getting this error.</p>

<pre><code>if (is_array($_POST['wmeet']))
    foreach ($_POST['wmeet'] as $key =&gt; $value) 
    $_POST['wmeet'][$key] = mysql_real_escape_string(stripslashes($value));
    $wmeet = implode(" ",$_POST['wmeet']);

    echo '&lt;pre&gt;'; print_r($wmeet); echo '&lt;/pre&gt;';
</code></pre>
