提交表单时缺少页脚

Question

表单页面本身一切正常，但提交表单后，回显中缺少页脚。我正在收到电子邮件并且标题在那里，问题只是页脚。这是整个页面的代码。有两种单独的表格，一种用于加入，一种用于编辑信息。提交表单后也不显示页脚。 错误日志说

PHP 解析错误：语法错误，意外的 'echo' (T_ECHO)，期待 ',' 或 ';'

Answer 1

您的代码中某些 echo 之前有语法错误。 在错误日志中检查它中断的行，或者手动跟踪它设置一些打印或转储。 您应该尝试编写更具可读性的代码（缩进，不要混合那么多 html 和 php），因为这是此类错误的主要来源。

它说期望'，'或';'，所以它可能是一个未闭合的数组或函数，或类似的东西。您发布的代码没有显示任何静态错误，因此它可能是动态生成的。

这些，例如：

<? if ($enablefave == 'Y'){ ?>
// stuff
<? } elseif ($_POST['action'] == "join"){ 

这使您的代码很难遵循，因此很难跟踪错误。 你有这样的语法来做到这一点：

<?php if ($a == 5): ?>
A is equal to 5
<?php endif; ?>
