Trying to Integrate TinyMCE to Symfony 6 Project? Follow This Step-by-Step Guide!

Are you a Symfony 6 developer struggling to integrate TinyMCE into your project? Well, you’re in luck! This article will walk you through the entire process, from installing TinyMCE to configuring it to work seamlessly with your Symfony 6 application. Buckle up and let’s dive in!

Why Choose TinyMCE?

TinyMCE is one of the most popular and feature-rich WYSIWYG editors available. It’s used by millions of websites worldwide and offers a wide range of customization options, plugins, and integrations. With TinyMCE, you can create a rich text editing experience for your users, complete with formatting options, media uploads, and more.

Prerequisites

Before we begin, make sure you have the following installed:

• Symfony 6 (obviously!)
• Composer (you should have this installed alongside Symfony)
• A code editor or IDE of your choice

Step 1: Install TinyMCE via Composer

The first step is to install TinyMCE using Composer. Open your terminal and navigate to your Symfony project directory. Run the following command:

composer require tinymce/tinymce

This will download and install TinyMCE and its dependencies. Be patient, as this may take a few minutes.

Step 2: Configure TinyMCE

Once the installation is complete, create a new file called `tinymce.php` in your project’s `config` directory. This file will contain the configuration settings for TinyMCE.

<?php
// config/tinymce.php

$container->setParameter('tinymce.config', [
    'base_url' => '/tinymce',
    'skin' => 'oxide-dark',
    'theme' => 'modern',
    'plugins' => [
        'advlist autolink lists link image charmap print preview hr anchor pagebreak',
        'searchreplace wordcount visualblocks visualchars code fullscreen',
        'insertdatetime media nonbreaking save table contextmenu directionality',
        'emoticons template paste textcolor colorpicker textpattern'
    ],
    'toolbar' => 'undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image',
    'image_advtab' => true,
    'images_upload_handler' => 'upload_image'
]);
?>

In this example, we’re configuring TinyMCE to use the `oxide-dark` skin, `modern` theme, and enabling various plugins and toolbar options. You can customize this to your heart’s content!

Step 3: Create a TinyMCE Service

Create a new file called `TinyMCEService.php` in your project’s `src/Service` directory. This service will handle the initialization and configuration of TinyMCE.

<?php
// src/Service/TinyMCEService.php

namespace App\Service;

use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;
use Symfony\Component\Filesystem\Filesystem;

class TinyMCEService
{
    private $parameterBag;
    private $filesystem;

    public function __construct(ParameterBagInterface $parameterBag, Filesystem $filesystem)
    {
        $this->parameterBag = $parameterBag;
        $this->filesystem = $filesystem;
    }

    public function initTinyMCE()
    {
        $config = $this->parameterBag->get('tinymce.config');
        $baseURL = $config['base_url'];

        if (!$this->filesystem->exists($baseURL)) {
            $this->filesystem->mkdir($baseURL);
        }

        return '
        ';
    }
}

This service will initialize TinyMCE and apply the configuration settings from our `tinymce.php` file.

Step 4: Register the TinyMCE Service

Register the `TinyMCEService` in your Symfony configuration file, typically `config/services.yaml`.

# config/services.yaml

services:
  app.tinymce_service:
    class: App\Service\TinyMCEService
    arguments:
      - '@parameter_bag'
      - '@filesystem'

This will make the `TinyMCEService` available as a service in your Symfony application.

Step 5: Integrate TinyMCE with Your Form

Now that we have our TinyMCE service set up, let’s integrate it with a form in our Symfony application. Create a new file called `FormType.php` in your project’s `src/Form` directory.

<?php
// src/Form/FormType.php

namespace App\Form;

use App\Service\TinyMCEService;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\OptionsResolver\OptionsResolver;

class FormType extends AbstractType
{
    private $tinyMCEService;

    public function __construct(TinyMCEService $tinyMCEService)
    {
        $this->tinymceService = $tinyMCEService;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('content', TextareaType::class, [
            'attr' => [
                'class' => 'tinymce'
            ]
        ]);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => 'App\Entity\MyEntity'
        ]);
    }
}

In this example, we’re creating a form type that includes a `content` field of type `TextareaType`. We’re also injecting our `TinyMCEService` into the form type.

Step 6: Render the Form with TinyMCE

Finally, let’s render the form in our Twig template, using the `TinyMCEService` to initialize the editor.

<!-- templates/form.html.twig -->

<h1>My Form</h1>

<form action="" method="post">
    {{ form_start(form) }}
    {{ form_widget(form.content) }}
    {{ tinymce_init() }}
    {{ form_end(form) }}
</form>

In this example, we’re rendering the form using the `form_start` and `form_end` Twig functions. We’re also calling the `tinymce_init()` function, which will initialize TinyMCE using the configuration settings from our `tinymce.php` file.

TinyMCE Configuration Options

TinyMCE offers a wide range of configuration options, including:

Option	Description
base_url	The base URL for TinyMCE assets
skin	The skin to use for TinyMCE (e.g. oxide-dark, lightgray)
theme	The theme to use for TinyMCE (e.g. modern, classic)
plugins	An array of plugins to enable (e.g. advlist, autolink)
toolbar	A string defining the toolbar layout
image_advtab	A boolean indicating whether to display the advanced image tab
images_upload_handler	A function to handle image uploads

This is just a small sample of the many configuration options available. Be sure to check out the TinyMCE documentation for more information.

Common Issues and Solutions

Here are some common issues you may encounter when integrating TinyMCE with Symfony:

• Error: TinyMCE not loading: Check that you have installed TinyMCE correctly and that the `tinymce.js` file is being loaded in your template.
• : Make sure you have initialized TinyMCE correctly in your service or controller.
• Error: Image uploads not working: Ensure that you have configured the `images_upload_handler` option correctly and that the upload function is working as expected.
