看起来就像：

<p class="floatLeft">

不在任何if或if/else的内部。我想你想要这样的东西：

<? if ($availabilitynotification->isProcessed()): ?>
<p class="bold">You will be notified - Thank you</p>
<? else: ?>
<p class="floatLeft">
Requesting e-mail availability notification for the following product:

<? endif; ?>

谢谢你，埃里克，这至少给了我正确的方向。我不得不把表格降到底部，这样剩下的表格就不会显示出来了。但在测试后它起了作用。再次感谢！很高兴你弄明白了！
