How to keep Lightbox tags?

I have the same problem. I used the advlink plugin in tinymce, so you can define styles or classes to a hyperlink. If I fillin a style for example "background:red" and I click update, the background of the link is indeed red in the TinyMCE editor. But if I click the SOURCE HTML button of tiny then the style isn't added. If I click on the hyperlink and than the hyperlink button the style is still set though.

If I save the node, the style is not saved.

Also as above if I add rel="external" of class="foo" trough the html source button as soon as I click UPDATE and click the html source button again it is gone.

TinyMCE strips out any attributes which are not defined in its init script. The trick, I think is to get the right settings in the tinymce init script. This is defined in admin/settings/tinytinymce.

If you alter TinyMCE init script for advanced mode in the line

extended_valid_elements : "... img[style|class=lightbox|src|border=0|..."

This puts the class on ALL img elements. I have not worked out how to control whether the attribute is there or not - but I hope this helps a little.

You could also alter the default valid elements directive, see http://wiki.moxiecode.com/index.php/TinyMCE:Configuration

The default is:

valid_elements : "@[id|class|style|title|dir<ltr?rtl|lang|xml::lang|onclick|ondblclick|"
+ "onmousedown|onmouseup|onmouseover|onmousemove|onmouseout|onkeypress|"
+ "onkeydown|onkeyup],a[rel|rev|charset|hreflang|tabindex|accesskey|type|"
+ "name|href|target|title|class|onfocus|onblur],strong/b,em/i,strike,u,"
+ "#p[align],-ol[type|compact],-ul[type|compact],-li,br,img[longdesc|usemap|"
+ "src|border|alt=|title|hspace|vspace|width|height|align],-sub,-sup,"
+ "-blockquote,-table[border=0|cellspacing|cellpadding|width|frame|rules|"
+ "height|align|summary|bgcolor|background|bordercolor],-tr[rowspan|width|"
+ "height|align|valign|bgcolor|background|bordercolor],tbody,thead,tfoot,"
+ "#td[colspan|rowspan|width|height|align|valign|bgcolor|background|bordercolor"
+ "|scope],#th[colspan|rowspan|width|height|align|valign|scope],caption,-div,"
+ "-span,-code,-pre,address,-h1,-h2,-h3,-h4,-h5,-h6,hr[size|noshade],-font[face"
+ "|size|color],dd,dl,dt,cite,abbr,acronym,del[datetime|cite],ins[datetime|cite],"
+ "object[classid|width|height|codebase|*],param[name|value|_value],embed[type|width"
+ "|height|src|*],script[src|type],map[name],area[shape|coords|href|alt|target],bdo,"
+ "button,col[align|char|charoff|span|valign|width],colgroup[align|char|charoff|span|"
+ "valign|width],dfn,fieldset,form[action|accept|accept-charset|enctype|method],"
+ "input[accept|alt|checked|disabled|maxlength|name|readonly|size|src|type|value],"
+ "kbd,label[for],legend,noscript,optgroup[label|disabled],option[disabled|label|selected|value],"
+ "q[cite],samp,select[disabled|multiple|name|size],small,"
+ "textarea[cols|rows|disabled|name|readonly],tt,var,big"

The img directive is on the 5th line of this and you would need to add "class" in there.

Here's how the entire init script would then look:

tinyMCE.init({
   mode : "exact",
   elements: "edit-body, edit-comment",
   file_browser_callback: "imceImageBrowser",
   theme : "advanced",
   convert_urls : false,
   plugins : "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
   theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,formatselect,fontselect,fontsizeselect, | |,forecolor,backcolor, ",
   theme_advanced_buttons2 : "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,preview,fullscreen,",
   theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,emotions,iespell,media,advhr,|,print,",
   theme_advanced_buttons4 : ",styleprops,|,cite,del,ins,attribs,|,visualchars,nonbreaking,template,pagebreak",
   theme_advanced_toolbar_location : "top",
   theme_advanced_toolbar_align : "left",
   theme_advanced_statusbar_location : "bottom",
   theme_advanced_resizing : true,
valid_elements : "@[id|class|style|title|dir<ltr?rtl|lang|xml::lang|onclick|ondblclick|"
+ "onmousedown|onmouseup|onmouseover|onmousemove|onmouseout|onkeypress|"
+ "onkeydown|onkeyup],a[rel|rev|charset|hreflang|tabindex|accesskey|type|"
+ "name|href|target|title|class|onfocus|onblur],strong/b,em/i,strike,u,"
+ "#p[align],-ol[type|compact],-ul[type|compact],-li,br,img[class|longdesc|usemap|"
+ "src|border|alt=|title|hspace|vspace|width|height|align],-sub,-sup,"
+ "-blockquote,-table[border=0|cellspacing|cellpadding|width|frame|rules|"
+ "height|align|summary|bgcolor|background|bordercolor],-tr[rowspan|width|"
+ "height|align|valign|bgcolor|background|bordercolor],tbody,thead,tfoot,"
+ "#td[colspan|rowspan|width|height|align|valign|bgcolor|background|bordercolor"
+ "|scope],#th[colspan|rowspan|width|height|align|valign|scope],caption,-div,"
+ "-span,-code,-pre,address,-h1,-h2,-h3,-h4,-h5,-h6,hr[size|noshade],-font[face"
+ "|size|color],dd,dl,dt,cite,abbr,acronym,del[datetime|cite],ins[datetime|cite],"
+ "object[classid|width|height|codebase|*],param[name|value|_value],embed[type|width"
+ "|height|src|*],script[src|type],map[name],area[shape|coords|href|alt|target],bdo,"
+ "button,col[align|char|charoff|span|valign|width],colgroup[align|char|charoff|span|"
+ "valign|width],dfn,fieldset,form[action|accept|accept-charset|enctype|method],"
+ "input[accept|alt|checked|disabled|maxlength|name|readonly|size|src|type|value],"
+ "kbd,label[for],legend,noscript,optgroup[label|disabled],option[disabled|label|selected|value],"
+ "q[cite],samp,select[disabled|multiple|name|size],small,"
+ "textarea[cols|rows|disabled|name|readonly],tt,var,big",
   extended_valid_elements : "a[name|href|target|title|onclick],img[style|class|src|border=0|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name],hr[class|width|size|noshade],font[face|size|color|style],span[class|align|style]",
   template_external_list_url : "example_template_list.js"
});
  

I've tried this and it seems to work - if you manually edit the html to have class="lightbox" the html is preserved. Would be nice if you could specify the class in the tinymce popup window but I can't see how to do that.

Thnx for finding out!! I will give it a try as soon as possible
