ckeditor plugin strinsert: how to set custom strings after initialization - ckeditor

Question

I'm trying to implement fixed placeholders to ckeditor by using plugins placeholder and strinsert as described here.
Unfortunately I'm not able to alter strings array of plugin strinsert dynamically.
This lines in config.js should work but it does not:
CKEDITOR.editorConfig = function( config ) {
config.strinsert_strings = [
['[[foo]]']
];
};
Maybe this plugin does not support altering strings array after init?
How could I do to present users different placeholders in different ckeditor instances without cloning strinsert plugin x times?
NB: I'm using newest versions of all of them.

Answer 1

Like suggested use the placeholder rplugin instead. Just edit the file ckedit/plugins/placeholder/dialogs/placeholder.js. Change the the element type to select and add the required value to items like in the following example:
contents: [
{
id: 'info',
label: generalLabel,
title: generalLabel,
elements: [
// Dialog window UI elements.
{
id: 'name',
type: 'select',
style: 'width: 100%;',
label: lang.name,
items:[
['ONE'],
['TWO'],
['THREE']
],
// SNIP...

You can set custom placeholders dynamically by using dialogDefinition event.
I did it like this (html attribute data-placeholders specifies the valid placeholders in form of "placeholder1,different text to show=placeholder2,another text=placeholder3"
CKEDITOR.on ('dialogDefinition', function (e) {
// Check if the definition is from the dialog window you are interested in (the "Link" dialog window).
if (e.data.name == 'placeholder') {
var $textarea = $(e.editor.element.$),
placeholders = $textarea.attr("data-placeholders"),
tab, ff, i, a;
//placeholders = [['placeholder1'],['Text to show', 'placholdervalue']];
if (placeholders && placeholders.length) {
// convert placeholders from desc1=val1,desc2=val2,val3,... format to array(array(desc,val))
placeholders = placeholders.split(",");
// ensure placeholders is array of arrays with exact 2 members
for (i = 0; i < placeholders.length; i++) {
a = placeholders[i].split("=");
if (a.length < 1) a[1] = a[0];
placeholders[i] = a;
}
tab = e.data.definition.getContents ('info');
// Set the default value for the URL field.
ff = tab.get ('name');
ff['type'] = 'select';
ff['items'] = placeholders;
}
}
});

For strinsert, I got it to work by editing its plugin.js, get rid of the strings declaration and replace with:
var strings = editor.config.strinsert_strings;
Then in your html before creating CKEDITOR:
CKEDITOR.config.strinsert_strings = [];
CKEDITOR.config.strinsert_strings.push(['myvalue1', 'myname1', 'mylabel1']);
CKEDITOR.config.strinsert_strings.push(['myvalue2', 'myname2', 'mylabel2']);
CKEDITOR.replace('mytextarea');
