External Plugins On TeenyMCE

[dylancb]

Hi,

I have tried to add an external plugin to TeenyMCE but it seems that it's not possible as if teeny is set in the wp-editor class, the external plugins script doesn't get loaded.

Is there any way this can be achieved, and if not could you add an action or the external plugins to the wp-editor for TeenyMCE, as well as Tiny.

Thanks

As far as I understand, this is more related to the TinyMCE minimal configuration option ("teeny") rather than to accessibility.

In wp-includes/class-wp-editor.php if I add the following, then it works. But I don't want to overwrite core files.

Line 355 under if( $set['teeny'] ) {

$ext_plugins = '';
                                        $teeny_mce_external_plugins = apply_filters( 'teeny_mce_external_plugins', array() );

if ( ! empty( $teeny_mce_external_plugins ) ) {

                                                /**

This code is directly from the else beneath it. May need further testing but I did a few quick tests and this made it work.

As @afercia said above, this is a minimal configuration for use in places that require only a minimal editing capabilities. It was intended for use in Press This but is not used in core any more.

In that terms don't think we should be adding any more filters to it. If you really need to, you can access all the TinyMCE options form the teeny_mce_before_init filter, including adding of external plugins.
