PHP + Python. Sending data from Moodle (php) to python CGI-script and get it back

I installed Learning Managment System (LMS) ‘Moodle’ to XAMPP local server. And there is instrument for file downloading, called “filepicker”.

I want to pass text, received from ‘filepicker’ instrument (uploading .txt files only) from LMS Moodle to python-CGI script, process it, get the processed data back, and echo it on a page.


OS - Windows 10.

Local server: Apache/2.4.53 (Win64) OpenSSL/1.1.1n PHP/7.4.28

python 3.10.4

I made var_dump($content); of uploaded file, So it is definitely a string:

string(828) “…my text here…”

Also I clearly know, that my CGI script work if i manually input data in it,like:

http://localhost/speciallocation/local/tokenize/ your text here

Output: [‘Enter’, ‘your’, ‘text’, ‘here’]

But when I press submit button, I only get the name of my file, since I don’t transmit it to CGI, but simply echo it.

If just echo content of file, It also works. It brings me to think, that there is something wrong with send&get data part…

Any thoughts people?

My php code:


require_once(DIR . '/../../config.php');
require_once($CFG->dirroot . '/local/tokenize/classes/forms/tokenization.php');
$PAGE->set_url(new moodle_url('/local/tokenize/tokenization.php'));
$PAGE->set_title(get_string('TOKENIZATOR', 'local_tokenize'));

$mform= new tokenization();
echo $OUTPUT->header();
if ($mform->is_cancelled()) {
    //Handle form cancel operation, if cancel button is present on form
} else if ($fromform = $mform->get_data()) {
  //In this case you process validated data. $mform->get_data() returns data posted in form.
  $name = $mform->get_new_filename('userfile');
  echo $name. '<br>';
 $content = $mform->get_file_content('userfile');
 //echo $content;
  $morgot_link = "http://localhost/diplom/local/tokenize/" . $content;
  $morgot_data = file_get_contents($morgot_link);
  echo $morgot_data;
} else {
  // this branch is executed if the form is submitted but the data doesn't validate and the form should be redisplayed
  // or on the first display of the form.

  //displays the form

echo $OUTPUT->footer();
My CGI python code:


import os
import urllib.parse
import nltk

query_dict = urllib.parse.parse_qs(os.environ['QUERY_STRING'])
input_something = str(query_dict['someamountoftext'])[2: -2]
def tknz_wrd(someamountoftext):

print("Content-Type: text/html\n")

print (tknz_wrd(input_something)) - the name of my CGI python file.

Addition: I checked if the $content of file is being placed into $morgot_link:

$morgot_link = "http://localhost/diplom/local/tokenize/" . $content;
  echo $morgot_link;

Yes, the output for this is correct:

http://localhost/diplom/local/tokenize/ text here…

It pushes me to think, that the problem is with receiving part (But I don’t completely deny probability with sending part issue). Also I think there could be some kinds of restrictions\permissions in Moodle to recieve data like that.

I followed these instructions for CGI-python script:

step 2) Build a Web API with Python -

step 3) Call Python (Web API) from PHP -
