Question

I am having a problem getting TinyMCE to wrap the contents of the selection.

The first style_format simple adds the class to the selected element, this works fine.

The problem is with the second style_format I want it to wrap the selected elements inside of the

E.g.
BEFORE

<p>test text</p>
<p>test text</p>
<p>test text</p>
<p>test text</p>

AFTER

<p class="accordion_top">test text</p>
<div class="accordion_middle">
<div class="accordion_middle-wrapper">
    <p>test text</p>
    <p>test text</p>
    <p>test text</p>
</div>
</div>

Using the jQuery version I have below, the code in question is the bottom style formats

$("#tinymce").tinymce({
    script_url : HOME+"/webapp/shared/javascript/tiny_mce/tiny_mce.js",
    mode : "textareas",
    theme : "advanced",

    "div[class|id]",
    content_css : TEMPLATE_HOME+"/css/tinymce.css?" + new Date().getTime(),

         {title : 'Accorion Middle', block : 'div', classes : 'accordion_middle'}
    ],
    setup: function (ed) {
        // Create an wrap DIV button
        ed.addButton ('wrap_div', {
            'title' : 'Wrap Accordion',
            'image' : HOME+'/webapp/shared/javascript/tiny_mce/themes/advanced/img/createlink.gif',
            'onclick' : function () {
                var text = ed.selection.getContent({ 'format' : 'text' });
                if (text) {
                    tinyInsert('<div class="accordion_middle"><div class="accordion_middle-wrapper">' + text + '</div></div>');
                }
            }
        });
    }
});

It requires big changes in the tinymce core (Formatter.js) to get what you want using the style plugin.
I would write an own function placed in an own tinymce plugin.
To achieve your goal you wouldn’tneed that much code.

EDIT: You got it almost correct. Try this first using spans to make sure this works in your editor.

setup: function (ed) {
    // Create an wrap DIV button
    ed.addButton ('wrap_div', {
        'title' : 'Wrap Accordion',
        'image' : HOME+'/webapp/shared/javascript/tiny_mce/themes/advanced/img/createlink.gif',
        'onclick' : function () {
            var text = ed.selection.getContent({ 'format' : 'text' });
            if (text && text.length > 0) {
                ed.execCommand('mceInsertContent', false, '<span class="accordion_middle"><span class="accordion_middle-wrapper">' + text + '</span></span>');
            }
        }
    });
}

Next step will be to replace the spans withs divs and make sure your tinymce settings will allow nested div tags (see the valid_children setting).
