PHP - Running Python In Linux With Tk Root?

I am a bit desperate about this problem that I have been trying to solve for several days now.

I'm trying to run a Python script from the exec() function in php. The script is called but the print job is never executed. 

This process has been running for several years and for no clear reason it suddenly stopped working.

On my home computer, it works without any problem. In my virtual machine, nothing happens. The print() functions present in the script are well displayed by the return value received by php but the printing is not executed.

The virtual machine is a test environment, in production it is also an physical machine.

PHP

<?php
        exec("py C:\xampp\htdocs\test\test.py", $out, $res);
        echo "<pre>";
        print_r($out);
    	echo "</pre>";
    echo "<pre>";
    	print_r($res);
	echo "</pre>";
?>

PYTHON

if __name__ == "__main__":
  try:
    filename = "C:/xampp/htdocs/test/test.pdf"
    win32api.ShellExecute(0, "print", filename, None, ".", 0)
    except Exception as e:
      print(f "An error occured during print_pdf : {e}")

The two environments are approximately the same:
* Build 1909
* Python 3.9.5
* Apache 2 & php > 7
* local user member of the administrators group
* local user owner of the apache2 service
* Same printer configured by default

I'd like to point out that running the script directly from the CLI works on both machines.

On the problematic machine, exec() only returns the result of print(..) 

I already opened a thread a few months ago about this problem but received no response.

Thank you in advance.
 

Having problems pointing to where files are.

Is this the root?:

Code: [Select]
include "../connectdb.php";
That file is locate din the root.  If I am already in the root when I include that statment, the file isn't found.  If I use the above code while I am in the subdirectory hello, (root/hello), it works.

 I use this in every page, so I think I need a way to point to the absolute root, not relative.

Hi guys,

I've got a simple script that I'm running from a folder above the root (as a cron job).

I've tried the script in the httpdocs folder and it works fine.

Code: [Select]
mail('email@example.com', 'Before include', '', 'From:<email@example.com>');

// include the myriad class
include($_SERVER['DOCUMENT_ROOT'].'/path/to/class');

mail('email@example.com', 'After include', '', 'From:<email@example.com>');

// initiate and instance of our class
$obj = new class_name;

$email = $obj->email;

$file = $obj->file_name;

mail('email@example.com', 'End of file', $email.' & '.$file, 'From:<email@example.com>');
If I run this file in httpdocs, it's fine and I get all emails.

If I run this from 1 folder above the root (from a cron job), I get the first 2 emails but not the last one, suggesting that the include hasn't worked.

Could this be a permissions problem?
I have tried running the cron job as both root and apache and changed the owner/group of the script to match.

Is there a reason why includes won't work above the root?

If I an deep inside of nested folders, how do I get back to the Web Root (as far as directory notation goes)??

Hi,
I want to get root path and use on links even if i'm in sub to sub folder etc...
suppose my site name is fitness.com and having two subfolder. so url will become

http://www.fitness.com/dir/dir_sub

here i want to put a link to go to root directory file. there are different ways to do that. e.g:

Code: [Select]
<a href='../../filename.php'>go to that page</a>

but i want to use some constant that always shows to root directory. as i defined here

Code: [Select]
define("SERVER_NAME" , $_SERVER['HTTP_HOST']);
//and used it like this
<a href='<?php echo SERVER_NAME;  ?>/filename.php'>go to that page</a>

it works when we're on root directory. but when we go to sub directory it added sub directory name with it. which i don't want.

is there any way?

Thanks

Hi,

I have a dynamic variable like this:

/def/g/qaz/pol/cxz/cba/abc

I only wish to keep this:

/def/g/qaz/pol/cxz

How would I do this?

Thanks,

I have been getting a lot more client requests to protect files.  What is the easiest way to do this. 
So, basically I have tried doing it outside the public directory. There are too many things that cause
issues with this. I haven't been able to get a successfull implementation of this since I started working with this.

So I was thinking instead about password protecting a directory that is inside public view, but still get files via PHP.  Is
there a way to setup a password protected directory, then retreive stuff from that directory using PHP.

Or, a good way to put them outside the public folder. Everything I have tried to do to get a file to save outside of public view,
has not worked. It always says uploaded but the file is never there. Also, I have verified correct permission for this as well.

Hi All,

I googled this and there is endless results.  I went through a lot of them but couldn't get this working properly.

How do I link from within my web site root to files outside the root?  It works for me using relative links  i.e.  ../../phpfiles/includes but that is going to get messy and I can't get a way of doing absolute links to work.  If someone could lay that out so a newbie can get it clearly I would really appreciate it!


Also - I understand why I should put all of my php files outside the web root but is this a guaranteed way to secure these files other than someone hacking my ftp access?


I've looked at a few site hierarchy examples - Am I right that the only pages within the web site root should be template pages with calls to required files (outside the root), session checks, and content includes and all other includes that have php executable code should be outside the root?

I really appreciate the advice and insight.  Thank you!

hey guys im still having a issue with using the root path when requiring external files. So i can use one path and never have to worry about this issue.

require("/functions/function_battle.php");
the file is located here
Code: [Select]
C:\Software\XAMPP\xampp\htdocs\System_Lords\functions\function_battle.php
i dont understand (include_path='.;C:\Software\XAMPP\xampp\php\PEAR')
im suppose to be including the php folder or something?


Code: [Select]
Fatal error: require() [function.require]: Failed opening required '/functions/function_battle.php'
 (include_path='.;C:\Software\XAMPP\xampp\php\PEAR') in
 C:\Software\XAMPP\xampp\htdocs\System_Lords\include\battle.php on line 2

is there a way in php to link from the root dir ?

like in html you just use the '/' at the start for the link " <a herf="/link.php" ></a> "

but i noticed this does not work when using php like include or require.

so is there anywey to tell a link to start from root dir? without using the ../../link.php

Hi all,

I like to write scripts for my Aastra IP phone. 480i.

I have done all my scripts with Apache on windows. I thought I would try it on Linux with the AsteriskNOW FreePBX 1.4 load. Phone system software for those that do not know.

So my code is below something very simple to display on the screen. Ignore the $textmenu code that works fine. The problem is it does not open a file and do something then write the file.

On my Windows / Apache box the screen will display  on the phone and open the file and do whatever. On my Linux box it will display the screen fine but will not open that file.

Why would it be ingnoreing those PHP file commands? Any ideas? It file commands work if I run it with php script.php but not when I use my phone to launch that script. Now keep in mind Windows/Apache is fine no problem. I thought maybe it was a php.ini setting on the linux box?

<?php
$textmenu = "<AastraIPPhoneTextMenu style = \"numbered\">\n";
$textmenu .= "<Title>------- Test -------</Title>\n";

$textmenu .= "<MenuItem>\n";
$textmenu .= "<Prompt>Applications</Prompt>\n";
$textmenu .= "<URI>http://65.205.71.13/xml/menu/menu.php?source=all</URI>\n";
$textmenu .= "</MenuItem>\n";

$textmenu .= "<SoftKey index = \"1\">\n";
$textmenu .= "<Label>Select</Label>\n";
$textmenu .= "<URI>SoftKey:Select</URI>\n";
$textmenu .= "</SoftKey>\n";

$textmenu .= "<SoftKey index = \"6\">\n";
$textmenu .= "<Label>Exit</Label>\n";
$textmenu .= "<URI>SoftKey:Exit</URI>\n";
$textmenu .= "</SoftKey>\n";

$textmenu .= "</AastraIPPhoneTextMenu>\n";

echo $textmenu;



$fp=fopen("/var/www/html/aastra/awa-det/conference/test.txt","w+");
fwrite($fp);
fclose($fp);
?>

Because I have include files in a subdirectory called "incl", I cannot rely on using relative paths because that include file is in a header on and the pages are in multiple subdirectories (or in the root).  I need some way to get the location of the root (the one where my index file is located).  I want to use something like this:

$path= $_SERVER['DOCUMENT_ROOT'];
include $path."/subdirectory/file.php";

However, when I use $_SERVER['DOCUMENT_ROOT'] I get :
/home/content/j/p/f/name55/html/

which is not where the index file sits.
Any ideas on how to get the directory where my index file sits? (i.e. the index that gets read when you got to www.domain.com)

Hi guys,

I am trying to retrieve some information from sessions. I have this in my header.php

   <?php if(isset($_SESSION['username'])){
         
         $username = $_SESSION['username'];
         
         echo $username;
} ?>

Hey y'all.   I'll gladly admit that I'm not a server guy - I have the utmost respect for people comfortable enough with *nix to handle Apache setup and configuration in a production environment. I can noodle about in *nix typically without killing anything vitally important, but trust me when I say no-one wants me to be a server administrator. That having been said, I do have a development server behind my home network firewall running Ubuntu that I use to test and develop the sites that I create on my separate Windows box. So I try to keep up with the way a shared server would be set up in a real-world situation, to a degree. For instance, I haven't bothered setting up the mail server or FTP, but I do create virtual host files for each of my projects.   So, I've got a virtual host set up on the directory /var/www/myAwesomeSite.com/ with the .conf file containing the following configuration:

<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	ServerName myAwesomeSite.com
	DocumentRoot /var/www/myAwesomeSite.com/www
	<Directory /var/www/myAwesomeSite.com/www>
		AllowOverride All
	</Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Now, in my php scripts echoing out $_SERVER['DOCUMENT_ROOT'] gives me 'myAwesomeSite/www' as I would expect. And using $_SERVER['DOCUMENT_ROOT'] in any require() statements actually does include the requested file, so that part seems to be working fine. My question is this: when I use a leading slash ('/'), shouldn't that equate to the document root? I use it at work all the time and it works flawlessly, but on the dev server I have set up here, it's a no-go. Is there another config command that I need to issue to make it work, or am I crazy?   Basically, am I missing a setting somewhere that will make this:

require_once('/path/to/my/include.php');

work like this?

require_once($_SERVER['DOCUMENT_ROOT'].'/to/my/include.php');

*edit* I just realized that I used the wrong slash in the title of this post, but I don't see a way to change the topic title. crap.

Hello! I was working on a simple url generator, but than i though to myself, why not put everything in the root. I've heard thats not a good idea, but i'm ot sure why. I can immagine it gets really messy when you have a lot of files, but its also easy, if you ask me.

I was just wondering what your view on this is. What are the pros and what are the cons?

Thanks
