PHP - Find Out If Error When A File Was Included

How can i find out parent (including) file of included file?
Lets imagine that we want to for example auto_prepend file to each file on our server that would write out the name of file  its being executed. I know, i can use PHP_SELF but what if i want to write name of file which is already included?

I have a web page and i want on it show its name even if it was included, but not the included page itself is showing name but auto_prepend file to each php file, its duty of this auto_prepend_file to write it out i dont want myself to echo it on each page? do you feel me?

how to get the name of the file including a file from the included file,

This one has me mixed up a bit.. I am trying to record site activity information from a common.php file using a user object. But since the file is included into different php files based on different situations I need a dynamic way of finding the file name that is including it. I could be over complicating things but right now this seems like the best solution other wise I'll have to rewrite the code on every page i write. Is there a function for doing this? Or if someone gets what I'm trying to do if they could point me to the direction of some more information on it.

Thanks.

I understand that this is a header error but i still do not know how to fix it.
I am trying to create a login box that is in the top right corner of my site. Once the user uses it to log in they need to be redirected to the account page. i include the login_box.php file in the appropriate div. however the file uses header("Location: account.php"); to redirect the user. because this file is included after the header i receive Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\index.php:17) in C:\xampp\htdocs\layout_inc\login_box.php on line 76
What would be the correct way to do this. My code is bellow. Thank you in advance

Hello:

I have this code in an included file:
myNav.php
Code: [Select]
function spLeftMenu() {
$spLeftMenu =
"
<p>
<div id=\"myLeftNavPaper\">
<img src=\"images/sidePaperTop.png\" alt=\"\" />

<div id=\"myLeftNavPaper2\">

echo \". $mySideBarPageData .\"

</div>

<img src=\"images/sidePaperBottom.png\" alt=\"\" />
</div>

</p>

";
return $spLeftMenu;
}

I can not get:
Code: [Select]
echo \". $mySideBarPageData .\"

To display the results on this page:
Page.php
Code: [Select]
<html>
...

<?php echo spLeftMenu(); ?>

...
</html>


What am I missing ??

Hi,
My issue here is that I cant get my if/else statement to work on my secondary page. I include my secondary page (fine.php) from my index page. However, I have an if/else statement in fine.php that keeps reverting back to the index.php and, therefore, outputs the else statement (404.php)

here is the if/else on index.php (these links work fine):

<?php
if($_SERVER['QUERY_STRING']=='/index.php' || $_SERVER['QUERY_STRING']=='')
{
include 'port.php';
}

elseif (isset($_GET['pos'])){
include 'pos.php';
}

elseif (isset($_GET['web'])){
include 'web.php';
}

elseif (isset($_GET['fine'])){
include 'fine.php';
}

        else {include '404.php';}






here is the if/else on my secondary page (fine.php). These links are supposed to alert the if/else in the next table cell. However, they instead alert the if/else in index.php.


<td><br/>
<a href="?backset"><img src="fine/thumbs/x-backset.jpg" border="0"></a><br/><br/> 
<a href="?backside"><img src="fine/thumbs/x-backside.jpg" border="0"></a><br/><br/> 
<a href="?bannerprint"><img src="fine/thumbs/x-bannerprint.jpg" border="0"></a><br/><br/> 
<a href="?chopu"><img src="fine/thumbs/x-chopu.jpg" border="0"></a><br/><br/> 
</td>
<td><br/>
<div id="DivPiece" align="left">
<?PHP 

if (isset($_GET['backset'])){
       include 'fine/backset.php';
}

elseif (isset($_GET['backside'])){
     include 'fine/backside.php';
}

elseif (isset($_GET['bannerprint'])){
     include 'fine/bannerprint.php';
}

elseif (isset($_GET['chopu'])){
include 'fine/chopu.php';
}

?>
</div>
</td>



How can I get the links on the secondary page to only alert the if/else statement on that page, and BLOCK the if/else statement on index.php from seeing them? I still want to use the query string though.

Thanks!
