I want to start output buffering, modify the buffer by adding a php file, then flush the buffer.
Here is my auto_prepend:
<?
function output_buffer($output) {
$site_menu = file_get_contents('site_menu.php',1);
$output = eregi_replace("<body>", "<body>".$site_menu, $output);
return $output;
}
ob_start(output_buffer);
?>
Here is my auto_append:
<?php ob_end_flush();?>
If site_menu.php is only HTML, it works fine. But if site_menu.php includes PHP and HTML, then the PHP code is not parsed since file_get_contents is accessing a local path. Now if I change this line:
$site_menu = file_get_contents('site_menu.php',1);
$site_menu = file_get_contents('http:www.domain.com/includes/site_menu.php');
I then decided to create a test file with the following contents:
<?
$string = eval('?'.'>'.file_get_contents('site_menu.php',1).'<'.'?');
echo $string;
?>
So next I tried replacing the $site_menu line with:
$site_menu = eval('?'.'>'.file_get_contents('site_menu.php',1).'<'.'?');
Here's where I'm confused. $site_head is empty after executing this line. The eregi_replace does nothing, since $site_head is empty. Even though it worked fine in the test file, it does not work in this one.
I'm baffled by this.
I'm wondering if it is because the output is being buffered, where as it was not in the test file.
Any thoughts?
But it seems to me that you are doing some thing simple in a complicated way.
You can usually use
include('site_menu.php');
and you can include it after <body> tag as well.
<html>
<body>
<?php include('site_menu.php');?>
.... rest of the things ...
</body>
</html>
I realize that I can simply put an include in the HTML file itself.
My goal, however, is to include a menu and other stuff in the display of HTML files without actually changing the HTML files themselves.
For example, let's say I have a file called test.html:
<html>
<head>
<title>Test</title>
</head>
<body>
Test Message
</body>
</html>
What I'd like to do is insert a menu immediately after <body> when test.html is viewed in a browser without changing test.html.
Right now, I do that by auto-prepending a php script that captures the output of test.html to a buffer, modifies that buffer, then releases the modified buffer to the browser.
Does that make sense?
$site_menu = readfile(\"php://filter/resource=http://www.example.com/site_menu.php\");

Here's where I'm confused. $site_head is empty after executing this line.
Where did $site_head come from? It was $site_menu before ...?
Here's the meat of it:
AUTO_PREPEND
<?
ob_start();
include 'site_menu.php';
$site_menu = ob_get_contents();
ob_end_clean();
ob_start();
?>
AUTO_APPEND
<?
$output = ob_get_contents();
ob_end_clean();
$output = eregi_replace("<body([^>]*)>", "<body".'\1'.">".$site_menu, $output);
echo $output;
?>
In the auto_prepend, I buffer the include so I can then store it in the variable $site_menu. I then clean out the buffer without sending it to the browser, then start buffering again. The HTML file is then buffered and stored in another variable, $output. Again, the buffer is cleaned out without sending it to the brwoser. I then modify $output to add the $site_menu right after <body>. Finally I echo $output (the whole, modified document) to the browser.
Thank you for taking the time to try to help!
