How to generate files with a custom module and PHP? - php

Question

I have a site with Drupal 8. I have created a custom module. Here is its code :
https://github.com/S1BIOSE/generator_website
generator-website-page.html.twig :
<div class="card mb-5 overflow-hidden shadow rounded bg-white">
<div class="card-body">
<form>
<legend>Générateur de site web</legend>
<div class="mb-3">
<label for="TokenUrl" class="form-label">L'URL de votre site web</label>
<input type="text" class="form-control is-invalid" id="TokenUrl" required>
<div class="invalid-feedback">
Ce champ est requis.
</div>
<small id="helpUrl" class="form-text">Entrez l'URL complète de votre site web.</small>
</div>
<div class="mb-3">
<label for="TokenTitle" class="form-label">Nom de l'entreprise</label>
<input type="text" class="form-control is-invalid" id="TokenTitle" required>
<div class="invalid-feedback">
Ce champ est requis.
</div>
<small id="helpTitle" class="form-text">Entrez le nom de votre entreprise.</small>
</div>
<div class="mb-3">
<label for="TokenDescription" class="form-label">Présentation de l'entreprise</label>
<textarea class="form-control is-invalid" id="TokenDescription" rows="5" required></textarea>
<div class="invalid-feedback">
Ce champ est requis.
</div>
<small id="helpDescription" class="form-text">Entrez une description de votre entreprise.</small>
</div>
<div class="mb-3">
<label for="TokenFeed" class="form-label">Fil d'actualité</label>
<input type="text" class="form-control" id="TokenFeed">
<small id="helpFeed" class="form-text">Entrez l'url de votre Flux RSS sur la plateforme S1BIOSE.</small>
</div>
<button type="submit" class="btn btn-primary">Générer</button>
</form>
</div>
</div>
What should I put in my module to generate the 3 files above and replace the words starting with Token ?
In this custom module, I created a form with IDs (I'm not sure if this is the right way to go). For example, the data entered in the TokenTitle field must replace TokenTitle wherever it appears in the files.
When a user submits the form, it must download the 3 files with the correct data (the one entered in the form). If possible in a ZIP archive.
It is unnecessary to keep the information submitted in the form in the database.
manifest.json

"orientation":"portrait",
"short_name": "TokenTitle",
"name": "TokenTitle",

Answer 1

Don't use standard PHP to make the file, as then you'll need to handle housekeeping/ removing it/ managing it as well. Drupal has BinaryFileResponse for sending files to users and \Drupal\Core\File\FileSystemInterface for creation/ management of files. If it is temporary, then simply set it as this.

Hello ok there are the things you will need to know how todo do:
Learn how to make files with php: https://www.w3schools.com/php/php_file_create.asp
learn how Drupal routing and controllers work:
https://www.drupal.org/docs/drupal-apis/routing-system/introductory-drupal-8-routes-and-controllers-example
learn how Drupal handles forms https://www.drupal.org/docs/drupal-apis/form-api/introduction-to-form-api
once you know these things then you can use on form submit
some php to generate your files and then probably group them for download ...or what ever your doing with them.
