See if @ symbol is in field and proceed with form validation
<p>I am trying to set up a web form for my website and I want to search the user's input for an @ symbol and if it is not there, the form should not validate and a message should show up asking the user to recomplete the form.</p>

<p>Here's what I have so far:-</p>

<pre><code>$at = "@";
if (is_null($at[$email]))
{
return FALSE;
}
</code></pre>

<p>I hope someone can help me!</p>
