Unable to transfer variables between two files !

Hello there,

 

I am developing a project in which there are different files in different folders:

 

ROOT -> INDEX.PHP

<?php
require_once( 'includes/core.php' );
?>

 

INCLUDES -> CORE.PHP

<?php
// Where we are ?
define( 'BASEPATH', $_SERVER['DOCUMENT_ROOT'] . '/csm/' );

// require config.php
if ( file_exists(BASEPATH . 'config.php') )
require_once ( BASEPATH . 'config.php' );
else
die ( 'Master configuration file not found, can\'t continue.' );

// Include common sessions file
if ( file_exists( BASEPATH . 'includes/common.php' ) )
{
require_once( BASEPATH . 'includes/common.php' );
}
else
{
die ( 'Common include file not found. Possible location: ' . BASEPATH . 'includes/common.php' );
}

// Require functions.php
if ( file_exists(INCLUDEPATH . 'functions.php') )
require_once ( INCLUDEPATH . 'functions.php' );
else
die ( 'Functions file not found, can\'t continue.' );

// Include common library file
if ( file_exists( BASEPATH . 'lib/classes.php' ) )
{
require_once( BASEPATH . 'lib/classes.php' );
}
else
{
die ( 'Common library file not found. Possible location: ' . BASEPATH . 'lib/classes.php' );
}

// Create a new instance of DB class.
$_DB = new DB;

if ( file_exists( BASEPATH . 'template/index.php' ) )
html_header_location ( 'template/index.php' );
else
die ( raise_error('03') );

?>

 

None of the files included in the above CORE.PHP file ( config.php, common.php, functions.php, classes.php, and template/index.php ) detect the value of BASEPATH.

 

Every file is filled with error:

Notice: Use of undefined constant BASEPATH - assumed 'BASEPATH'...

 

I am just confused performing the use of GLOBAL (global) variables/constants in either files.

 

Anyone, please help.

are you saying that the included files can't access the defined variable? or that the files aren't being included because the the code you listed above doesn't seem to load the defined variable currently?

 

if its the latter, maybe the issue isn't that the variable doesn't exist but that the path it stores is not the actual base path to your files.

 

is the folder that all those files are in really "csm"  and not maybe something more common like "cms"?

There's nothing technically wrong what what you are doing (just tested.)

 

Are you sure $_SERVER['DOCUMENT_ROOT'] is actually what you think it is (a file system path)? Perhaps someone either mis-configured your virtual host or intentionally set it so that it actually contains the URL to your domain root?

Yes, if I call the constant BASEPATH from any of the above stated files, its giving me warning messages. and what do you mean by LOAD THE DEFINED VARIABLE CURRENTLY.

 

I have also checked the file, and the paths, all are configured correctly.

My localhost is working perfectly... How can I check that its configured properly???

You can echo $_SERVER['DOCUMENT_ROOT'] to see what it is.

 

Its showing the path in my site-available settings.

 

Why the constant BASEPATH not being accessed by other files?

 

Here is the sample of common.php in the includes directory:

 

<?php

// Common path definitions
define( 'INCLUDEPATH', BASEPATH . 'includes/' );
define( 'DATAPATH', BASEPATH . 'data/' );
define( 'LIBPATH', BASEPATH . 'lib/' );
define( 'REPORTSPATH', BASEPATH . 'reports/' );
define( 'TEMPLATESPATH', BASEPATH . 'template/' );

$_LF = "\n";
$_TAB = " ";

$_CHARSET = CHARSET;

// declare some session variables after starting a pure session

$_SESSION['curdate'] = Date('d-m-Y');

// define URL path
$_BASE_HREF = 'http://' . DBHOST . '/csm/';

?>

 

Here is the error/warning:

 

Notice: Use of undefined constant BASEPATH - assumed 'BASEPATH' in .../csm/includes/common.php on line 13

 

Even I had removed the BASEPATH definition from common.php file and shifted to Index.php on root folder:

 

<?php

define( 'BASEPATH', $_SERVER['DOCUMENT_ROOT'] . '/csm/' );

require_once( BASEPATH . 'includes/core.php' );                 // Here it is no problem, but after this ... blah blah !!!

?>

 

Please help...

What exactly would that value be, because it's the most likely reason for the problem you are having (i.e. including a file using a URL/URI instead of a file system path)?

 

Oh ! how to solve the problem, please tell...

 

Here is my site-available setting:

Finally, at least that eliminates the $_SERVER['DOCUMENT_ROOT'] variable as the cause of the problem.

 

At this point, you would need to post enough of your code that duplicates the problem (if the exact code you post does not duplicate the error, don't waste time posting it) if you want someone to help further and is there any chance you have multiple include/core.php folders/files at different starting paths, some with and some without the define() statements and you might be including the wrong one?

 

Also, why are you using require_once instead of require (php has had a number of bugs in the _once versions)?

I had done replacing all the require_once with require directive. Secondly, there is no other file naming core.php in the include directory.

Without actual code to test with that reproduces the problem, sorry, but you cannot be helped.

 

Why are you not cooperating when someone is trying to help you? You are doing something in your code on your server that does not work and you want someone who is not standing right next to you to help you troubleshoot what your code is doing, but without actually having enough of the code that reproduces the problem. This is like you have a dead battery in your car and someone stopped to give you a jump start and you refuse to open the hood of your car.

 

I'm going to make a wild guess. You originally had the paths hard-coded into your logic and have just recently added the defined constant, but the core.php file never got edited/saved to the correct actual folder so it does not have the define() statements in it but the files that are being required did get edited/saved to the correct actual folder, so they are attempting to reference the defined constant, but the file where the defined constant should be at is the old code without the defined constant.

Sorry, I am really sorry, i couldn't want to hurt you. I am sending you the zip coded file of my project. Please help me.

The code you posted works for me.

 

Again, the most likely problem is that your actual $_SERVER['DOCUMENT_ROOT'] value is a URL (http://something) so that the files are being included/required through a URL instead of through the file system. Echo $_SERVER['DOCUMENT_ROOT'] in the index.php file to see what it is.

The code is including core.php and core.php is including common.php (based on the last error message you posted.) The next most likely problem is that in your common.php file, the name BASEPATH has been corrupted. I would delete and then re-type BASEPATH to see if that corrects the problem. Delete and re-type the white-space before and after BASEPATH as well.

This is what I am getting:

 

Notice: Use of undefined constant BASEPATH - assumed 'BASEPATH' in /home/abc/server/csm/includes/error.php on line 31
Notice: Undefined variable: _LF in /home/abc/server/csm/includes/error.php on line 44

 

where ever the word $_LF and BASEPATH came. Do you want some setting details from Apache2 or PHP5

Users should not "bump" topics that are still on the first page of the forums. If you bump' date=' you must provide additional information. If you resort to bumping, chances are your question needs to be re-thought and re-described (see Eric Raymond's "How To Ask Questions The Smart Way").[/quote']
