Well, the structure of site is simple:
site.com
'config' folder
config.php
cesar.php
'login' folder
index.php
index.php
Config.php:
include_once '../config/cesar.php';
At site.com/index.php:
Warning: include_once(../config/cesar.php): failed to open stream: No such file or directory
At site.com/login/index.php everything is OK.
If I will remove one dot (./config/cesar.php), main index will become OK and login page will get the error.
How to make both codes work?
The .. in your path are used to go up a directory because of that the file won't exist where you are looking for it.
If you update it to be include_once 'config/cesar.php'; it should work since that will allow it to go down into the config directory rather than try to find a directory with the name of config 1 level above where index.php is located.
./ works since . is the notation for the current directory.
To answer your question, it wouldn't be possible to have the code work by using a relative path since both the files are in different locations on the server in relation to the one you want to include. If you want to have something that does then you will need to use an absolute path rather than the relative path. This would be something like /path/to/webdirectory/site.com/path/to/file/config.php (i.e. /home/charles/websites/site.com/config/config.php) in *nix and C:\path\to\webdirectory\site.com\path\to\file\config.php on windows.
In PHP you should be able to get the absolute path in a dynamic way by using the $_SERVER['DOCUMENT_ROOT'] variable. Ex: include_once $_SERVER['DOCUMENT_ROOT'] . '/config/cesar.php';
Warning: include_once(../config/cesar.php): failed to open stream: No such file or directory
I ran into a similar problem once. You need to remember that (./config/xxx.php) and (config/xxx.php) mean the same thing but (../config/xxx.php) will go up a directory and find the config folder and xxx.php file in it.
You can also use $base_url as a prepend string to all your paths to make it clean. Where:
$base_url = 'http://' . $_SERVER['SERVER_NAME'];
Then replace your paths like
../config/xxx.php
with
$base_url.'/config/xxx.php'

this is kind of a silly question, but as I can't sort it out I thought it might be good to get some help. The point is that the ".. /" to go back directory is not working.
The file I'm executing is in a folder that's on the main route and I need to go back to the main route and then enter another folder to load this other PHP file but it's not working what could be causing this issue.
ERRORS:
Warning: require_once(../PHPMailer/PHPMailerAutoload.php): failed to open stream: No such file or directory in things/public_html/classes/Mail.php on line 3
Fatal error: require_once(): Failed opening required '../PHPMailer/PHPMailerAutoload.php' (include_path='.:/opt/alt/php71/usr/share/pear') in things/public_html/classes/Mail.php on line 3
DIRECTORY STRUCTURE:
File where the requiere once is:
/public_html/classes/filethatwantstoacces.php
File where it wants to get:
/public_html/PHPMailer/PHPMailerAutoload.php
require_once('../PHPMailer/PHPMailerAutoload.php');
What you should be using is the $_SERVER['DOCUMENT_ROOT'] variable. Please read this answer to another question for details.
If you are using PHP you should get into a habit of NOT using relative file paths at all but to use absolute paths, which will guarentee to succeed every time (As long as the target file exists and is reachable, etc.).
so; use $_SERVER['DOCUMENT_ROOT']
As a side note, you do not need to use brackets for your includes/requires, it's simply giving the server more work to do for no extra benefit.
The $_SERVER['DOCUMENT_ROOT'] is the base directory of your PHP/web application, typically the contents of the folder /public_html.
Using correct syntax and the above $_SERVER value (which will point to the /public_html folder you will have:
require_once $_SERVER['DOCUMENT_ROOT'].'/PHPMailer/PHPMailerAutoload.php';
This will work from any script within your directory structure, if the file (PHPMailerAutoload.php) exists and is reachable at that given location
Given your location
/public_html/classes/filethatwantstoacces.php
doing ../ gives you
/public_html/classes
so ../PHPMailer/PHPMailerAutoload.php evaluates to
/public_html/classes/PHPMailer/PHPMailerAutoload.php
As #Martin has pointed out, using $_SERVER['DOCUMENT_ROOT'] to construct an absolute path to your file is the easiest way to avoid relative directory navigation errors such as this:
require_once $_SERVER['DOCUMENT_ROOT'].'/PHPMailer/PHPMailerAutoload.php';
For requiring files in my PHP scripts I am using the following code :
require(dirname(__FILE__)."/../config.php");
with the config.php file being located a level higher than the file requiring it. However this appears to not work and the file cannot be located, with the following error :
failed to open stream: No such file or directory in /home3/**myusername**/public_html/PHP/access/login.php on line 3
I'm not sure what the error is as I have looked online and this appears to be the way others have done it. I believe however that the /.. is not causing it to go up a level.
EDIT 1
I changed the code to
require_once($_SERVER['DOCUMENT_ROOT'] . "/PHP/config.php");
and still receive the same error.
EDIT 2
The reason I am using an absolute path is because I have been led to believe this will work no matter where I call the file from, i.e if a file in a different directory includes this file (for this particular file it wont be the case but it will be in other files where I will use this) it will still include the config.php file correctly and not relative to the path of the file that included login.php.
EDIT 3
if I vardump the require path it prints the following :
string(52) "/home3/*myusername*/public_html/PHP/access/../config.php"
so obviously not going to the right location.
EDIT 4
Absolute path of file being required
/home3/*myusername*/public_html/PHP/config.php
Absolute path of file requiring it
/home3/*myusername*/public_html/PHP/access/login.php
try providing relative path to root. This is a better approach then providing relative to current file.
require_once($_SERVER['DOCUMENT_ROOT'] . "/config.php");
Remove the first / - "../config.php"
I am an amateur web developer and I am trying to get my site live for the first time. The site is working and all of the files are uploaded but the site is not loading my PHP includes.
Here is the error message:
Warning: include(includes/header.php) [function.include]: failed to open stream: No such file or directory in /home4/myUsername/public_html/index.php on line 3
How can I get PHP to look in public_html/ rather than public_html/index.php?
EDIT: I have tried editing the include path. It doesn't seem to change where php is looking for the file. Additionally my includes work properly in localhost.
I'm going to assume this is your folder structure:
public_html/index.php
public_html/includes/header.php
Generally (not always), $_SERVER['DOCUMENT_ROOT'] will now reflect the path to the base public_html directory (this I'm assuming based on the context of your message). This means you can always point to the root this way. - no matter if you have /index.php or /my/deep/file/structure.php
Try this with your include statement on index.php
<?php
include($_SERVER['DOCUMENT_ROOT'] . '/includes/header.php');
You may need to change the include path in your php.ini file or use set_include_path() to change the include path.
Here is the manual entry for the function call if you'd like to read more about it.
Have you checked already the include file?
in given. include(folder_includes/file_header.php);
There's a little library I'm trying to plug in to my project. This lib has some includes and requires across classes, so I'm trying to set an include path for all that to work.
When trying to set an include path off a sibling branch, I run into a hiccup.
For a reference point, require('/../my/test.php') works fine.
So does
set_include_path('/../');
require_once('my/test.php');
But once I try
set_include_path('/../my/');
require_once('test.php');
I get:
Warning: require_once(one.php): failed to open stream: No such file or directory in ...
What am I missing?
Starting your paths with / means look in the root directory, so /../ is technically one directory above the root directory.
To set the include path to the parent directory of the current location, you just need ../. To make the code more portable I would suggest combining it with dirname(__FILE__) to get the absolute path of the current directory.
IE:
set_include_path(dirname(__FILE__) . '/../my/');
Note the preceding / is required in that example as dirname() does not return a trailing slash
PHP-programmers!
I've got a problem with the Include-function in PHP.
I have a website which contains a left column-bar, and that column contains dynamic content which I get with the Include-function with a relative path, because absolute paths isn't available in the Include-function.
When I navigate to other files in other folders I get the error: include(folder/fileToBeIncluded.php) [function.include]: failed to open stream: No such file or directory in /home/mywebsite/public_html/thissite/folder/subfolder/leftcolumn.php on line 3
How am I going to deal with that? I am totally lost, and I've been searching for Google and StackOverflow for about 10 minutes now.
Thank you!
Absolute paths are can be used with the include statement.
Try:
include $_SERVER['DOCUMENT_ROOT'] . '/folder/fileToBeIncluded.php';
// or
include dirname(__FILE__) . '/../fileToBeIncluded.php'; // relative to the path of the file doing the include
At the very least, you can hardcode the path to be absolutely sure (until you move your site elsewhere):
include '/home/yoursite/public_html/folder/fileToInclude.php';
Please see include documentation.
May I suggest creating a dedicated "includes" folder? Something like:
/home/mywebsite/includes
in php.ini, you'd need to add:
include_path = "/home/mywebsite/includes/"
That way, all calls to include check from /home/mywebsite/includes for the file you need before looking for it relative to the location of the current page being process.
