Magento - How to allow certain tags (iframe, embed) in Magento's CMS editor?

I would like to allow to enter certain html tags such as iframe and embed in Magento's CMS editor. Ma开发者_如何学Cgento does not allow those tags.

Is there a model or controller that I can edit to allow iframe and embed tags?

Look in this file: js/mage/adminhtml/wysiwyg/tiny_mce/setup.js

Find this block of code:

    var settings = {
        mode : (mode != undefined ? mode : 'none'),
        elements : this.id,
        theme : 'advanced',
        plugins : plugins,
        theme_advanced_buttons1 : magentoPlugins + 'magentowidget,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect',
        theme_advanced_buttons2 : 'cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,forecolor,backcolor',
        theme_advanced_buttons3 : 'tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,iespell,media,advhr,|,ltr,rtl,|,fullscreen',
        theme_advanced_buttons4 : 'insertlayer,moveforward,movebackward,absolute,|,styleprops,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,pagebreak',
        theme_advanced_toolbar_location : 'top',
        theme_advanced_toolbar_align : 'left',
        theme_advanced_statusbar_location : 'bottom',
        theme_advanced_resizing : true,

and add this after it:

        extended_valid_elements : 'iframe[src|style|width|height|scrolling|marginwidth|marginheight|frameborder],style,script',

It's a simple comma delimited list of tags you want to allow.

Josh is right on target, I added this row to accept a "Find us on Faceb..."-iframe:

extended_valid_elements : 'iframe[src|style|width|height|scrolling|marginwidth|marginheight|frameborder|allowTransparency],style,script',

It has an extra attribute that's within the autogenerated FB-iframe.

When editing a CMS page, you can switch to an html view.

By pressing the html button

There you are able to add the iframe onto the page right in the html
