MathType for TinyMCE
Reading time: 7min
Before you continue reading
The following article assumes the MathType integrations architecture. We encourage you to grasp the architecture to properly understand the Frontend and Services notation and choose the appropriate deployment to satisfy your needs.
Demos and integration downloads
Collaborative mode
Note MathType is compatible with TinyMCE's collaborative mode, allowing your users to write equations simultaneously in a shared document.
Requirements
- TinyMCE 5 or higher installed.
- A valid license to install the integration in a production environment; otherwise, you can use the downloaded file just for demo purposes.
Frontend + Cloud Services
npm installation steps
General installation
Requirements:
- npm (v6.13.4)
Steps:
Note
Notice steps below assume the following directory structure:
└───index.html
└───node_modules
└───@wiris/mathtype-tinymce<VERSION_X>1. Install the MathType for Tinymce npm module:
npm install @wiris/mathtype-tinymce<VERSION_X>
Where <VERSION_X> can be 4 .x.x or 5.x.x or >= 6.1.0
2. Load the module into your project:
<script src="node_modules/@wiris/mathtype-tinymce<VERSION_X>/wiris.js"></script>
3. Update TinyMCE configuration options with our recommended settings:
// Set up the editor.
└───@wiris/mathtype-tinymceX
tinymce.init({
selector: '#editor',
external_plugins: {
tiny_mce_wiris: 'node_modules/@wiris/mathtype-tinymce<VERSION_X>/plugin.min.js',
},
// This option allows us to introduce mathml formulas
extended_valid_elements: '*[.*]',
// We recommend to set 'draggable_modal' to true to avoid overlapping issues
// with the different UI modal dialog windows implementations between core and third-party plugins on TinyMCE.
// @see: https://github.com/wiris/html-integrations/issues/134#issuecomment-905448642
draggable_modal: true,
plugins: ['image', 'media'],
toolbar: 'tiny_mce_wiris_formulaEditor tiny_mce_wiris_formulaEditorChemistry',
// language: 'fr_FR',
// You could set a different language for MathType editor:
// mathTypeParameters: {
// editorParameters: { language: 'de' },
// },
});
Caution
For Tinymce versions 6.x.x, the extended_valid_elements option is mandatory for the proper operation.
// This option allows us to introduce mathml formulas
extended_valid_elements: '*[.*]',React
Requirements:
- npm (v6.13.4)
Steps:
1. Run the following through the terminal.
Note
Notice that $APP_NAME needs to be replaced by the name that you choose.
create-react-app $APP_NAME cd $APP_NAME
npm install --save @tinymce/tinymce-react
npm install tinymce
npm install @wiris/mathtype-tinymce6
npm install jquery --save2. Replace all the content in src/index.js by:
// Default create-react-app imports
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import reportWebVitals from './reportWebVitals';
// Import the react editor TinyMCE component.
import { Editor } from '@tinymce/tinymce-react';
// Add jquery.
import $ from 'jquery';
// Load wiris formula render script.
const jsDemoImagesTransform = document.createElement('script');
jsDemoImagesTransform.type = 'text/javascript';
jsDemoImagesTransform.src = 'https://www.wiris.net/demo/plugins/app/WIRISplugins.js?viewer=image';
document.head.appendChild(jsDemoImagesTransform);
// This needs to be included before the '@wiris/mathtype-tinymce6' is loaded synchronously
window.$ = $;
window.tinymce = require('tinymce'); // Expose the TinyMCE to the window.
// Load wiris plugin synchronously.
require('@wiris/mathtype-tinymce6');
// Set the initial editor content
const content = '<p class="text"> Double click on the following formula to edit it.</p><p style="text-align:center;"><math><mi>z</mi><mo>=</mo><mfrac><mrow><mo>-</mo><mi>b</mi><mo>±</mo><msqrt><msup><mi>b</mi><mn>3</mn></msup><mo>-</mo><mn>4</mn><mi>a</mi><mi>c</mi></msqrt></mrow><mrow><mn>2</mn><mi>a</mi></mrow></mfrac></math></p>';
// Init the editor and define its options
const options = {
height: 500,
menubar: false,
// Add wiris plugin
external_plugins: {
'tiny_mce_wiris' : `${window.location.href}/node_modules/@wiris/mathtype-tinymce6/plugin.min.js`
},
plugins: [
'advlist autolink lists link image charmap print preview anchor',
'searchreplace visualblocks code fullscreen',
'insertdatetime media table paste code help wordcount '
],
toolbar: [
' bold italic |' +
'tiny_mce_wiris_formulaEditor tiny_mce_wiris_formulaEditorChemistry '
],
htmlAllowedTags: ['.*'],
htmlAllowedAttrs: ['.*'],
extended_valid_elements: '*[.*]',
};
/* Create a component to be rendered later.
This is important to remove complexity from the reactDom.render
and to be able to add other functionality. */
class EditorTiny extends React.Component {
render() {
return (
<Editor init ={ options } initialValue = { content } />
);
}
}
ReactDOM.render(<EditorTiny />, document.getElementById('root'));
// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: https://bit.ly/CRA-PWA
reportWebVitals();
3. Add the following script on the head of your HTML file:
<script src="https://cdn.tiny.cloud/1/no-api-key/tinymce/6/tinymce.min.js" referrerpolicy="origin"></script>
4. Finally, you are ready to run the development server through the specified command
npm run start
Angular
Requirements:
- npm (v6.13.4)
Steps:
1. Run the following through the terminal.
Note
Notice that $APP_NAME needs to be replaced by the name that you choose.
ng new $APP_NAME
cd $APP_NAME
npm install --save @tinymce/tinymce-angular
npm install --save tinymce
npm install --save @wiris/mathtype-tinymce62. Edit src/app/app.module.ts as shown below:
// Import the tinymce options
import { EditorModule, TINYMCE_SCRIPT_SRC } from '@tinymce/tinymce-angular';
// Expose tinymce instance to the window
declare const require: any;
(window as any).tinymce = require('tinymce');

})3. Add the following in the .angular.json.
"assets": [
...
{ "glob": "**/*", "input": "node_modules/tinymce", "output": "/tinymce/" }
...
]
...
"scripts": [
...
"node_modules/tinymce/tinymce.min.js"
...
]4. Replace the content of the src/app/app.component.ts file with the code below.
import { Component } from '@angular/core';
// Load WIRISplugins.js dynamically
const jsDemoImagesTransform = document.createElement('script');
jsDemoImagesTransform.type = 'text/javascript';
jsDemoImagesTransform.src = 'https://www.wiris.net/demo/plugins/app/WIRISplugins.js?viewer=image';
// Load generated scripts.

// Define the initial options of the editor
public options: Object = {
base_url: '/tinymce', // Root for resources
suffix: '.min', // Suffix to use when loading resources
// Add wiris plugin
external_plugins: {
'tiny_mce_wiris' : `${window.location.href}/node_modules/@wiris/mathtype-tinymce6/plugin.min.js`
},
htmlAllowedTags: ['.*'],
htmlAllowedAttrs: ['.*'],
// This option allows us to introduce mathml formulas
extended_valid_elements: '*[.*]',
// We recommend to set 'draggable_modal' to true to avoid overlapping issues
// with the different UI modal dialog windows implementations between core and third-party plugins on TinyMCE.
// @see: https://github.com/wiris/html-integrations/issues/134#issuecomment-905448642
draggable_modal: true,
plugins: ['image', 'media'],
toolbar: 'undo redo | styleselect | bold italic | image media | tiny_mce_wiris_formulaEditor tiny_mce_wiris_formulaEditorChemistry',
// language: 'fr_FR',
// You could set a different language for MathType editor:
// mathTypeParameters: {
// editorParameters: { language: 'de' },
// },
};
}
Note
Notice that the content can be empty or set as you prefer in the component.
5.Edit src/app/app.component.html and replace its contents with:
<h1>TinyMCE 6 Angular Demo</h1>
<editor
id="editor"
[init]="options"
[initialValue]="content"
></editor>
6. Finally, you are ready to run the development server through the specified command.
ng serve
Add the Services to the Frontend
If you need additional configurations (e.g., MathType's editor customization or specific cache storage destination), you need to install the integration services.
These services are available for various technologies. Click on the technology you are using to see full instructions.
Java
To install the Java services follow the steps below:
- Download the MathType Web Integration Services - Java package.
- Deploy the pluginwiris_engine war file.
- Add the following attribute to TinyMCE configuration:
tinymce.init({
mathTypeParameters : {
serviceProviderProperties : {
URI : '/pluginwiris_engine/app/configurationjs',
server : 'java'
}
}
}PHP
To install the PHP services follow the steps below:
- Download the MathType Web Integration Services - PHP package.
- Copy the generic_wiris/integration folder into your project. For this example we are assuming that the services are located at
DOCUMENT_ROOT/php-services/ - Add the following attribute to TinyMCE configuration:
tinymce.init({
mathTypeParameters : {
serviceProviderProperties : {
URI : 'http://localhost/php-services/integration',
server : 'php'
}
}
}External integration
Some rich text editors, such as CKEditor or TinyMCE, allow you to specify a URL based location of plugins outside of the normal plugins directory.
This option is useful when loading the rich text editor from a CDN or when you want to have the editor directory separate from your custom integrations. In case you are using a programing language for which MathType Integrations are not available this is also a good option.
You can install MathType integration as an external integration and TinyMCE. Using this option you do not need to install any component on your servers. You only need to add the following line to your TinyMCE configuration.
Frontend + On-Premises Services
Our integration is available for various technologies. Click on the technology you are using to see full instructions.
1. Copy files and configuration
Unzip the tinyMCE MathType integration and copy the tiny_mce_wiris directory into your tinyMCE plugins directory. For example, you will have tiny_mce/plugins/tiny_mce_wiris. The name of the MathType integration directory must be tiny_mce_wiris.
Technologies
Our integration is available for various technologies. Click below on the technology you are using to see full instructions you should follow.
Java Servlet
- Install the pluginwiris_engine.war in your Java web applications server. For example, tomcat.
- Give write permissions to
pluginwiris_engine/cacheand topluginwiris_engine/formulasdirectories to the web server user. Those folders will be used to store formula MathML codes and temporal images. If you prefer, you can configure the location of these folders .
Configuration
Edit tiny_mce/plugins/tiny_mce_wiris/configuration.ini to set your own values.This table specifies all possible parameters.
For versions older than 3.50.0 it is essential to set the value of the parameters wiriscachedirectory and wirisformuladirectory.
PHP
-
mbstringextension must be installed and enabled in the server. - Give execution rights to the web server user on the PHP files contained at to
ckeditor/plugins/ckeditor_wiris/integration. - Give write permissions to
ckeditor/plugins/ckeditor_wiris/cache and tockeditor/plugins/ckeditor_wiris/formulasdirectories to the web server user. Those folders will be used to store formula MathML codes and temporal images. If you prefer, you can configure the location of these folders. - Very large formulas may not be rendered if the output_buferring option is enabled. Either disable it or set a high enough value in your server's
php.inifile.
Configuration
Edit configuration.ini file on wirispluginengine gem root directory. This table specifies all possible parameters.
2. Include it in your platform
Note: This step may be specific to your platform (i.e: ILIAS).
You must activate tiny_mce_wiris on your tinyMCE integration list (see tinyMCE documentation). You can also include these buttons on your tinyMCE button list:
tiny_mce_wiris_formulaEditor
tiny_mce_wiris_formulaEditorChemistry
3. WIRISplugins.js
Add WIRISplugin.js script. Follow this instructions.
4. Testing
In order to check if the integration is installed correctly, there is a page that makes some tests on your server. Open this link to see where is your test page.
5. Custom MathType properties
The parameters used when creating formulas (font color, background color, transparency...) are defined in the configuration.ini file. However, it is possible, in specific cases, that these values must be overriden at runtime or that there must be two editors with different configurations running at once.
To solve the problem, it offers the possibility to specify settings for the integration in the TinyMCE initialization.
The following snippet of Javascript code shows the available parameters and how to set their values:
tinyMCE.init({
...
wirisimagebgcolor: '#FFFFFF',
wirisimagesymbolcolor: '#000000',
wiristransparency: 'true',
wirisimagefontsize: '16',
wirisimagenumbercolor: '#000000',
wirisimageidentcolor: '#000000',
wirisformulaeditorlang: 'es'
});
5. Clean and backup
