Contribute to this page
+ toolbar button + menu item

Important: The free TinyMCE Spell Checker plugin (spellchecker) was deprecated with the release of TinyMCE 5.4. For details, see the free TinyMCE Spell Checker plugin deprecation notice.

Note: The Spell Checker plugin is self-hosted only. The Spell Checker Pro plugin is provided for some Tiny Cloud plans. For information on the Spell Checker Pro plugin, see: Spell Checker Pro plugin.

This plugin enables TinyMCE’s spellcheck functionality. It also adds a toolbar button and the menu item Spellcheck under the Tools menu dropdown.

Type: String

Basic setup

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_rpc_url: 'spellchecker.php'
});

Options

These settings affect the execution of the spellchecker plugin by modifying how spellchecking is handled. If you need an introduction to setting up server-side spell checking with TinyMCE please refer to this section in the General Configuration Guide.

spellchecker_callback

This option lets you override the default server side request/communication logic for the spellchecker.

Example of a basic override without using a server

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_callback: function (method, text, success, failure) {
    var words = text.match(this.getWordCharPattern());
    if (method === "spellcheck") {
      var suggestions = {};
      for (var i = 0; i < words.length; i++) {
        suggestions[words[i]] = ["First", "Second"];
      }
      success({ words: suggestions, dictionary: [ ] });
    } else if (method === "addToDictionary") {
      // Add word to dictionary here
      success();
    }
  }
});

Example of fallback for the older JSON-RPC based format

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_callback: function (method, text, success, failure) {
    if (method === 'spellcheck') {
      tinymce.util.JSONRequest.sendRPC({
        url: '/tinymce/spellchecker.php',
        method: 'spellcheck',
        params: {
          lang: this.getLanguage(),
          words: text.match(this.getWordCharPattern())
        },
        success: function (result) {
          success(result);
        },
        error: function (error, xhr) {
          failure("Spellcheck error:" + xhr.status);
        }
      });
    } else {
      failure('Unsupported spellcheck method');
    }
  }
});

spellchecker_language

This configuration option lets you set the default language code for the spellchecker. This defaults to “en”.

Type: String

Default Value: en

Example: Using spellchecker_language

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_language: 'sv_SE'
});

spellchecker_languages

This option lets you specify a list of languages for the user to select from. The list is added to the spellcheck toolbar icon. The format is based on the 3.x spellchecker format.

Type: String

Default Value:

'English=en,Danish=da,Dutch=nl,Finnish=fi,French=fr_FR,' +
'German=de,Italian=it,Polish=pl,Portuguese=pt_BR,Spanish=es,Swedish=sv'

Example: Using spellchecker_languages

tinymce.init({
  selector: 'textarea',  // change this value according to your html
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_languages: 'English=en,Danish=da,Dutch=nl,Finnish=fi,French=fr_FR,' +
    'German=de,Italian=it,Polish=pl,Portuguese=pt_BR,Spanish=es,Swedish=sv'
});

spellchecker_rpc_url

This options enables you to specify a custom URL to be used for the spellchecker. This can be the spellchecker URL provided by the TinyMCE spellchecker packages or a URL to a page that you have in your system. The URL is relative to the spellchecker plugin.

Type: String

Example: Using spellchecker_rpc_url

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_rpc_url: 'spellchecker.php'
});

Spellchecker request format

The request is a HTTP POST with URL encoded parameters described below.

Parameter Description
method Default to “spellcheck” might be other things in the future for storing custom dictionaries etc.
text Text to spellcheck this will contain a plain text version of the current editor contents.
lang The currently selected language code for example “en” or “sv_SE”.

Spellchecker response format

The response of a successful spellcheck request should like this:

{
  "words": {
     "misspelled1": ["suggestion1", "suggestion2"],
     "misspelled2": ["suggestion1", "suggestion2"]
  }
}

And if there was an error:

{
  "error": "Error message"
}

spellchecker_wordchar_pattern

This option enables you to override the matching of characters that are parts of words. By default it will treat anything that isn’t a space, comma, dot, dash, quote, etc, as parts of a word. For some languages or environments it might be useful to override this behavior.

Type: String

Example: Using spellchecker_wordchar_pattern

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  plugins: 'spellchecker',
  menubar: 'tools',
  toolbar: 'spellchecker',
  spellchecker_wordchar_pattern: /[^\s,\.]+/g
