Hi Joyce,

I wonder how you get to that error. When installing the plugin, the default values should be set.
To get rid of the problem, please check that the following entries exist in the config_plugins table:
id | plugin | name | value
------+----------------+-----------------------+------------
| tiny_fontcolor | textcolors | []
| tiny_fontcolor | backgroundcolors | []

They are automatically set when installing the plugin.
I added a fix in the main branch that also should circumvent the problem.

Hi Tanja,

To get the colors into your Moodle, use the SQL command that Csaba wrote a few comments above. This sets the text colors. The background colors are set in the same way. The README.md contains information about the variable names.
You need to have access to your Moodle database to do this.

hello @Joseph,

Thanks for responding!
Adding the above list to the tiny_fontcolor textcolors table and the tiny_fontcolor backgroundcolors table makes the full textcolor_map available to your tiny_fontcolor plugin!

i am not a programmer - can you let me know where and how I have to add this particular list?

It would be so helpful to have a set of colours.

Thank you, Tanja

Hi Marius,

The pollyfill.js in the plugin has no relations with the pollyfill library. The code in that file was mostly used from the original color plugin of the TinyMCE (that natively offers quite the same two buttons but with a different setup). Some small parts of the code was written by me. All these are helper functions that provide basic functionality that is used in the plugin.
I cannot verify where the original code was taken from and howmit got into the TinyMCE. However, aftwr reading our link, the plugin has no relation to the current pollyfill library. It's entirely served whithin the project without using any CDN.

Best regards, Stephan

Hello Stephan,

We've had recent security scans on our Moodle sites and the polyfill.js raised some concerns as there's a vulnerability linked to that JavaScript library: https://sansec.io/research/polyfill-supply-chain-attack
Matt Porritt from Moodle HQ wrote that the Moodle core file of the same name is not the same as the one linked to the aforementioned vulnerability: https://moodle.org/mod/forum/discuss.php?d=459883

We're wondering, since we've found a similar JS file in your plugin, if this Javascript library is used by your plugin? Here's the path: /lib/editor/tiny/plugins/fontcolor/amd/src/polyfill.js

Thanks!

Hi Stephan,

Thank you for your quick answer. I tried this SQL command, and it works

Hi Csaba,

in one of the previous comments Joseph provided a color scheme. This color scheme is provided within the zip file (in the root folder) of the plugin. The README file contains an explanation on how to manually update it into your database. There is no button etc. that would fill this scheme via a click.
Best regards, Stephan

In the release notes there is some new info about the json scheme:
"Add json for a comprehensive color scheme (thanks to Joseph Rézeau)."
How can we use this function?
TIA

Thank you, Joseph, for the JSON with the color scheme. I will include it in the plugin.

Hi Stephan,
Thanks for responding!
Adding the following list to the tiny_fontcolor textcolors table and the tiny_fontcolor backgroundcolors table makes the full textcolor_map available to your tiny_fontcolor plugin!
[{"name":"Black","value":"#000000"},{"name":"Burnt orange","value":"#993300"},{"name":"Dark olive","value":"#333300"},{"name":"Dark green","value":"#003300"},{"name":"Dark azure","value":"#003366"},{"name":"Navy Blue","value":"#000080"},{"name":"Indigo","value":"#333399"},{"name":"Very dark gray","value":"#333333"},{"name":"Maroon","value":"#800000"},{"name":"Orange","value":"#FF6600"},{"name":"Olive","value":"#808000"},{"name":"Green","value":"#008000"},{"name":"Teal","value":"#008080"},{"name":"Blue","value":"#0000FF"},{"name":"Grayish blue","value":"#666699"},{"name":"Gray","value":"#808080"},{"name":"Red","value":"#FF0000"},{"name":"Amber","value":"#FF9900"},{"name":"Yellow green","value":"#99CC00"},{"name":"Sea green","value":"#339966"},{"name":"Turquoise","value":"#33CCCC"},{"name":"Royal blue","value":"#3366FF"},{"name":"Purple","value":"#800080"},{"name":"Medium gray","value":"#999999"},{"name":"Magenta","value":"#FF00FF"},{"name":"Gold","value":"#FFCC00"},{"name":"Yellow","value":"#FFFF00"},{"name":"Lime","value":"#00FF00"},{"name":"Aqua","value":"#00FFFF"},{"name":"Sky blue","value":"#00CCFF"},{"name":"Red violet","value":"#993366"},{"name":"White","value":"#FFFFFF"},{"name":"Pink","value":"#FF99CC"},{"name":"Peach","value":"#FFCC99"},{"name":"Light yellow","value":"#FFFF99"},{"name":"Pale green","value":"#CCFFCC"},{"name":"Pale cyan","value":"#CCFFFF"},{"name":"Light sky blue","value":"#99CCFF"},{"name":"Plum","value":"#CC99FF"}]

Hi Joseph,

Thank you for your positive feedback, that you find the plugin useful.

Answering your question:
All settings are stored at the database. The following query fetches you all settings:
select * from m_config_plugins where plugin = 'tiny_fontcolor';
The settings textcolors and backgroundcolors define the color palette. This is a simple json string:
[{"name": "color name", "value": "#hexcode"}]
You can have as many name/value tuples. The name string may contain html e.g. to have the color name defined in different languages:
[{"name":"Weiss<\/span>White<\/span>","value":"#ffffff"}

HTH, Stephan

Thanks for this useful plugin, which should really be part of the regular distribution of TinyMCE in Moodle! Anyway, it's working fine on my Moodle 4.3 sites. I have some question. Where are the settings saved? I would like to somehow upload the textcolor_map to be found at https://www.tiny.cloud/docs-4x/plugins/textcolor/#textcolor_map to my Moodle site to avoid the painful task of entering all those names and codes in the Moodle TinyMCE tiny_fontcolor_settings ADMIN page. Thanks!

Hello Mónica,

The database error should not be related with the installation of this plugin. It's a general error that the database cannot be reached. Can you ensure that the database is running (e.g. check the direct connection via the console or other tool), ans also think about what else did you modify in your installation when you were installing the plugin.

Best regards, Stephan

Hello:
After installing the plugin, we had the following error in Moodle 4.2:

Error: Database connection failed

It is possible that the database is overloaded or otherwise not running properly.

The site administrator should also check that the database details have been correctly specified in config.php
