我相信我发现我的表单使用 Firebug 存在问题。经过仔细检查，当有人在主页上时，我的表单操作被设置为 index.php。我把它改成了一个简单的/在萤火虫中，它起作用了。我的问题是该表单可以在某些页面上工作，而在其他页面上却不行。动作被设置为
<?php echo htmlentities($_SERVER['PHP_SELF']); ?>
在我的代码中。如何让它显示为 / 仅在主页上而不是 index.php 上。如果需要，我所指的站点和页面是“链接”处的主页。有问题的表格是通讯表格。导航到“链接”时会显示正确的地址。代码是：

不再需要的链接已删除。不使用 php_self 时是否可以清理 action=""？
