PHP从包含文件重定向

Question

When I add the php redirect command in an include file, it redirects just that area, in its little sub window.

How can I make a redirect work with the base page?

Is it even possible, because you can only redirect before the headers, can't you? Would I have to use javascript instead?

Answer 1

If you are not talking about iframes

You can use output buffering to get round this issue. At the beginning of your main script run:

ob_start();

And then once you are done at the bottom of your main script run:

ob_end_flush();

From the manual page linked above:

This function will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer.

The contents of this internal buffer may be copied into a string variable using ob_get_contents(). To output what is stored in the internal buffer, use ob_end_flush(). Alternatively, ob_end_clean() will silently discard the buffer contents.

Answer 2

If you want to redirect parent window from <iframe (I assume that's what you mean by "little sub window") you have to use javascript, probably: self.parent.location.href = '...';

Google for javascript parent redirect to get more examples.
