Server Side Scripting / Coding: variable value wasn't in the output file (PHP)
Bottom of Page1 to 3 of 3
-
This is my template.php file
template.php (located in: http://mysite.com/new/template.php)
...
<body>
<? echo $title; ?>
</body>
...
and this is my xxx.php file that will include template.php
xxx.php (located in: http://mysite.com/new/mission/xxx.php)
...
$title="Information";
include 'http://mysite.com/new/template.php';
...
------------------
The xxx.php shown in the browser will output the template file, without the values for $title. Can somebody:
(1) explains what happen?
(2) suggest what I should do to tackle the problem? Suppose I want to put xxx.php anywhere in my site. -
well, one piece of advice: don't include() the file using a full URL, use a local file path to it.
<?php
$title="Information";
include($_SERVER['DOCUMENT_ROOT'].'/new/template.php');
?>
$_SERVER['DOCUMENT_ROOT'] is an automatic reference to the root directory for the website the file is being served from, so all you need to do is tack file paths (to web accessible stuff, that is) onto the end of it. saves a little time over trying to figure out include('/home/myusername/www/sitename/new/template.php') or whatever other weird full paths you might be needing to use otherwise.
(Using include() on remote files is a big security no-no, and actually probably is why it won't pull that variable name in there. Otherwise what would stop you from using include('http://www.example.com/some/path/to/a/config.php'); and stealing someone else's DB information?) -
Very nice input.
Thank you so much, nifkin! And also for the security insight.
