https - PHP、HTTPS、表单提交

Question

我们最近切换到 HTTPS，当提交我们的一个表单时，Firefox 会弹出:

Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party.

Are you sure you want to continue sending this information?

在说"is"之后，表单提交并且页面只是重新加载，信息实际上并没有发布？

我错过了什么吗？

Answer 1

基本上，这意味着:

<form action="http://www..."

必须改为

<form action="https://www..."

因为我们没有提交到一个安全的 URL。
