Has anyone working code?

I also had no success with the HtmlEditorConfig, at the moment I customized framework/admin/_config.php :

// Default CMS HTMLEditorConfig
HtmlEditorConfig::get('cms')->setOptions(array(
	'friendly_name' => 'Default CMS',
	'priority' => '50',

	'body_class' => 'typography',
	'document_base_url' => isset($_SERVER['HTTP_HOST']) ? Director::absoluteBaseURL() : null,

	'cleanup_callback' => "sapphiremce_cleanup",

	'use_native_selects' => false,
	'valid_elements' => "@[id|class|style|title],a[id|rel|rev|dir|tabindex|accesskey|type|name|href|target|title"
		. "|class],-strong/-b[class],-em/-i[class],-strike[class],-u[class],#p[id|dir|class|align|style],-ol[class],"
		. "-ul[class],-li[class],br,img[id|dir|longdesc|usemap|class|src|border|alt=|title|width|height|align|data*],"
		. "-sub[class],-sup[class],-blockquote[dir|class],-cite[dir|class|id|title],"

		. "-div[id|dir|class|align|style],-span[class|align|style],-pre[class|align],address[class|align],"
		. "-h1[id|dir|class|align|style],-h2[id|dir|class|align|style],-h3[id|dir|class|align|style],"
		. "-h4[id|dir|class|align|style],-h5[id|dir|class|align|style],-h6[id|dir|class|align|style],hr[class],"
		. "dd[id|class|title|dir],dl[id|class|title|dir],dt[id|class|title|dir],@[id,style,class],article,section",
	'extended_valid_elements' => "img[class|src|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name"
		. "|usemap|data*],iframe[src|name|width|height|align|frameborder|marginwidth|marginheight|scrolling],"
		. "object[width|height|data|type],param[name|value],map[class|name|id],area[shape|coords|href|target|alt]"
));

I recently answered this on StackOverflow.

In SilverStripe 3.1 this worked for me. This is the code I have put in mysite/_config.php:

HtmlEditorConfig::get('cms')->setOption(
    'extended_valid_elements',
    'img[class|src|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name|usemap|data*],'
        . 'iframe[src|name|width|height|align|frameborder|marginwidth|marginheight|scrolling],'
        . 'object[width|height|data|type],'
        . 'embed[src|type|pluginspage|width|height|autoplay],'
        . 'param[name|value],'
        . 'map[class|name|id],'
        . 'area[shape|coords|href|target|alt],'
        . 'ol[start|type]'
        . 'address[class|name|id],'
        . 'article[class|name|id],'
        . 'aside[class|name|id],'
        . 'audio[class|name|id],'
        . 'bdi[class|name|id],'
        . 'caption[class|name|id],'
        . 'canvas[class|name|id],'
        . 'datalist[class|name|id],'
        . 'details[class|name|id],'
        . 'dialog[class|name|id],'
        . 'embed[class|name|id],'
        . 'figure[class|name|id],'
        . 'figcaption[class|name|id],'
        . 'footer[class|name|id],'
        . 'header[class|name|id],'
        . 'keygen[class|name|id],'
        . 'mark[class|name|id],'
        . 'menuitem[class|name|id],'
        . 'meter[class|name|id],'
        . 'nav[class|name|id],'
        . 'output[class|name|id],'
        . 'progress[class|name|id],'
        . 'rp[class|name|id],'
        . 'rt[class|name|id],'
        . 'ruby[class|name|id],'
        . 'section[class|name|id],'
        . 'source[class|name|id],'
        . 'summary[class|name|id],'
        . 'time[class|name|id],'
        . 'track[class|name|id],'
        . 'video[class|name|id],'
        . 'wbr[class|name|id]'
);

I think there cannot be any white space between the tags. Looking at the code in framework/admin/_config.php this seems to be how framework does it.

Works :D

hi there,
I have tried in _config.php of my project module as follows
// TinyMCE configuration customised
$educationEditor = HtmlEditorConfig::get('cwp');
$educationEditor->setOptions(array(
'friendly_name' => 'ERO Editor',
'extended_valid_elements' =>
'img[class|src|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name|usemap|data*],'
. 'iframe[src|name|width|height|align|frameborder|marginwidth|marginheight|scrolling],'
. 'object[width|height|data|type],'
. 'embed[src|type|pluginspage|width|height|autoplay],'
. 'param[name|value],'
. 'map[class|name|id],'
. 'area[shape|coords|href|target|alt],'
. 'ol[start|type]'
. 'address[class|name|id],'
. 'article[class|name|id],'
. 'aside[class|name|id],'
. 'audio[class|name|id],'
. 'bdi[class|name|id],'
. 'caption[class|name|id],'
. 'canvas[class|name|id],'
. 'datalist[class|name|id],'
. 'details[class|name|id],'
. 'dialog[class|name|id],'
. 'embed[class|name|id],'
. 'figure[class|name|id],'
. 'figcaption[class|name|id],'
. 'footer[class|name|id],'
. 'header[class|name|id],'
. 'keygen[class|name|id],'
. 'mark[class|name|id],'
. 'menuitem[class|name|id],'
. 'meter[class|name|id],'
. 'nav[class|name|id],'
. 'output[class|name|id],'
. 'progress[class|name|id],'
. 'rp[class|name|id],'
. 'rt[class|name|id],'
. 'ruby[class|name|id],'
. 'section[class|name|id],'
. 'source[class|name|id],'
. 'summary[class|name|id],'
. 'time[class|name|id],'
. 'track[class|name|id],'
. 'video[class|name|id],'
. 'wbr[class|name|id]'
));

but it still did not get worked.

Thanks in advance!

Cheers
