Add attributes to Insert Image dialogue of Umbraco RTE or Create Custom Data type

问题

How can I add attributes to the current Insert Image dialogue box on umbraco Richtext Editor?

What I really want is to let content editor choose images and set their class, and maybe choose if this is lightbox image or not. If user choose lighbox option, then a hyper link is added with some extra attributes, like data-rel. I even want to be able to modify the image url added by the content editor, if possible.

The output should look like this

<a href="/media/2813/DSC_2615.JPG" data-rel="prettyPhoto[gal-3-col]" >    
   <img src="http://domain.com/imageGen.ashx?
   image=%2fmedia%2f2813%2fDSC_2615.JPG&amp;width=420" alt="DSC_2615" title="DSC_2615" 
   class="alignright">
</a>

I found this very useful link http://forum.umbraco.org/yaf_postst8163_TinyMCE--insert-image-dialog.aspx which solve half of my issue, but I can't figure out how to continue

回答1:

Default umbraco tinymce add image interface is

<plugin loadOnFrontend="false">umbracoimg</plugin>

I was able to modify it to show additional field in the image selection interface, then render markup I want.

I edited \umbraco\plugins\tinymce3\insertImage.aspx, added my field there and some jquery logic:

<ui:PropertyPanel id="pp_desc" runat="server" Text="Description">
    <input type="text" id="title" style="width: 300px"/>
</ui:PropertyPanel>
...

Then if you are adding custom attributes, you might want to add them to \config\umbracoSettings.config

<!-- what attributes that are allowed in the editor on an img tag -->
<allowedAttributes>src,alt,title,border,class,style,align,id,name,onclick,usemap</allowedAttributes>

and \config\tinyMceConfig.config

<validElements>

  </validElements>

Then I modified the .js that is in charge of rendering html that will be added to tinymce editor:

\umbraco_client\tinymce3\plugins\umbracoimg\js\image.js

ed.execCommand('mceInsertContent', false, '<div id="__dimps_width" class="img-with-text"><img id="__mce_tmp" /><p id="__dimps_desc">description</p></div>', { skip_undo: 1 });
ed.dom.setAttribs('__mce_tmp', args);
ed.dom.setAttrib('__mce_tmp', 'id', '');
ed.dom.setAttribs('__dimps_width', {style: 'width: ' + nl.width.value + 'px;'});
...

One important thing: everything is cached and bundled, so to make sure your changes was applied remove all files from \app_data\TEMP\ClientDependency\ and use new instance of incognito browser. You probably can disable it somewhere, but I just removed the cache.

There is no magic in Umbraco TinyMCE. Just a bunch of .aspx and .js code. Modify it to your needs.
