Tiny MCE Editor stripping code - content-management-system

I currently have my extended_valid_elements set up as follows.
using EPiServer.Editor.TinyMCE;
namespace Customer.Web.Templates.Plugins.TinyMCE
{
[TinyMCEPluginNonVisual(AlwaysEnabled = true, EditorInitConfigurationOptions = "{ extended_valid_elements: 'iframe[*]' }")]
public class ExtendedValidElements
{
}
}
However, I need to add the ability to enter an extra entry next to a link, as the tinyMCE is currently stripping it out.
I cant seem to get the syntax right without crashing the edit mode of the site... my logic would suggest 'iframe[*]','a[data-lightbox]' }")] should do the trick, but it doesn't. I just get an error.
Any ideas? Many Thanks.
Marc.

According to the TinyMCE documentation,
When adding a new attribute by specifying an existing element rule
(e.g. img), the entire rule for that element is over-ridden so be sure
to include all valid attributes not just the one you wish to add.
So try
EditorInitConfigurationOptions = "{ extended_valid_elements: 'iframe[*], a[name|href|target|title|data-lightbox]' }")]
I would consider using an asterisk in place of the word 'lightbox' to allow any data attribute to be used.
if that doesn't work, you can find more information at about valid_elements and extended_valid_elements on the TinyMCE site.
Hope this helps

Use "," in extended_valid_elements TinyMCE

I need to do the following whith TinyMCE:
extended_valid_elements: a[href|onclick=window.open(this.href,'_system','location=no');return false;]
When doing this the character "," causes me problems and does not appear the default "onclick".
You can't put full code in extended_valid_elements - per the documentation (https://www.tinymce.com/docs/configure/content-filtering/#extended_valid_elements) its expecting attributes and (optionally) their default text. The JavaScript is not allowed and is messing up the parsing algorithm.
In extended_valid_elements you can reference onclick but you can't put the actual JavaScript in there.
If all you want is to allow JavaScript in your href values the allow_script_urls setting may do what you need without modifying extended_valid_elements:

How to auto-update matching html/xml tag in Code Mirror

I really like how Visual Studio html editor updates the matching tag. Example:
<h2>Header</h2>
If we replace <h2> opening tag with <h3>, then the closing tag should change automatically to </h3>. This should happen as we type.
I'm trying to implement this on my own, but no luck so far. I thought that matchtags addon would be a good starting point, but it stops working if tag names do not match.
Also, I noticed that xml mode marks closing tag as error on tag name mismatch, but I'm not sure how to use this to update the closing tags.
I would appreciate any help from more experienced CodeMirror users.
Thanks
So once the edit has been done, you no longer have the information needed to find the matching tag (which is why the matchtag addon can't help anymore). A good solution might be to track the current matching tag when editing starts (when the cursor is in a tag name) by using the CodeMirror.findMatchingTag function exported by the addon/fold/xml-fold.js file. Then, on "change" events that look like local editing inside the tag name (i.e. their start and end are inside the tag name), immediately follow up by modifying the matching tag.
add matchtags.js, xml-fold.js
config : matchTags: {bothTags: true}

CKEditor strips <i> Tag

I'm trying to find a solution to avoid CKEditor, but also the older FCKeditor strips out any
<i> tag from previously inserted content to the db.
Case:
I insert html content to the db, some content contain the <i> elements.
I do this with the CKEditor.
Everything works perfect and the content shows up on the webpage.
But when i want to edit the previously inserted content, the <i> elements are missing.
In my specific case i use:
<i class="fa-icon-fullscreen fa-icon-xxlarge main-color"></i>
Of course if i disable the editor, the content shows up just fine in the textarea.
When the protectedSource solution is used, i tags are no longer stripped, but img tags stop showing up in the WYSIWIG mode of CKEditor (I'm using 4.3.1). The solution that worked better for me is to disable removing empty i tags using CKEDITOR.dtd.$removeEmpty
For example, I added the following to the config.js
// allow i tags to be empty (for font awesome)
CKEDITOR.dtd.$removeEmpty['i'] = false;
Note: This should be placed outside the CKEDITOR.editorConfig = function( config ) function.
I found the solution for this specific problem i ran into with the <i> tag
The original answer i got from drupal forum
The fix or tweak (you name it) for it is to set the following into the ckeditors config.js:
// ALLOW <i></i>
config.protectedSource.push(/<i[^>]*><\/i>/g);
Thanks to Spasticdonkey for pointing me to the link.
Here is what works for me
add the 3 lines of code below in the same order in the drupal ckeditor profile setting
admin/config/content/ckeditor/edit/Full
ADVANCED OPTIONS >> Custom JavaScript configuration
config.allowedContent = true;
config.extraAllowedContent = 'p(*)[*]{*};div(*)[*]{*};li(*)[*]{*};ul(*)[*]{*}';
CKEDITOR.dtd.$removeEmpty.i = 0;
First line is pretty much turning off the advanced filtering
Second line is allowing ALL class (), any style {} and any attribute [*] for the p,div, li and ul.
The last line is for the empty tag...this line works with images...I have found that if you use
config.protectedSource.push(/]*></i>/g);
it strips out the tag while editing.
for 4.3 version ckeditor
in config.js (after config section) paste
CKEDITOR.dtd.$removeEmpty['b'] = false;
and write widget with code
CKEDITOR.plugins.add( 'bwcaret', {
requires: ['widget'/*, 'richcombo'*/],
icons: 'bwcaret',
init: function( editor ) {
editor.widgets.add( 'bwcaret', {
button: 'Create a caret',
template: '<b class="caret"></b>',
allowedContent: 'b(!caret)',
requiredContent: 'b(!caret)',
upcast: function( element ) {
return element.name == 'b' && element.hasClass( 'caret' );
},
});
}
});
There are two possible problems:
Read about Advanced Content Filter. CKEditor is removing elements which are not allowed, but you can extend filter's rules.
However, if the problem is that CKEditor removes empty <i> elements, then you need to find other way of using it. CKEditor is not a WYSIWYG website builder. It is a document editor, so the loaded content must have a meaning. Empty inline element does not have any meaning, therefore it is removed, because otherwise editor would not know what to do with it.
One of the possible solutions in the (near) future, will be to use Widgets system, to handle those empty elements. But for now I advice you to check the CKEDITOR.htmlDataProcessor and short guide how to use it.
i found a permanent solution for it.actually what happened ckeditor removing only blank tag.whatever the tag is, may b <i> tag or <span> tag
if you are using any icon like font-awesome,maeterlize icon etc ...
you can stop it by using below code in your config.js file
CKEDITOR.dtd.$removeEmpty.span = false;
CKEDITOR.dtd.$removeEmpty.i = false;
if you are using more blank tag then you need to add the tag name after $removeEmpty
CKEditor 4 removes emtpy tags, so here you can do trick without changing any config settings.
Replace
<i class="fa-icon-fullscreen fa-icon-xxlarge main-color"></i>
With
<i class="fa-icon-fullscreen fa-icon-xxlarge main-color"> </i>
Now <i></i> tag have content i.e. so CKEditor will not remove that tag.

CKEditor automatically strips classes from div

I am using CKEditor as a back end editor on my website. It is driving me round the bend though as it seems to want to change the code to how it sees fit whenever I press the source button. For example if I hit source and create a <div>...
<div class="myclass">some content</div>
It then for no apparent reason strips the class from the <div>, so when I hit source again it has been changed to...
<div>some content</div>
I presume this irritating behaviour can be turned off in the config.js, but I have been digging and cant find anything in documentation to turn it off.
Disabling content filtering
The easiest solution is going to the config.js and setting:
config.allowedContent = true;
(Remember to clear browser's cache). Then CKEditor stops filtering the inputted content at all. However, this will totally disable content filtering which is one of the most important CKEditor features.
Configuring content filtering
You can also configure CKEditor's content filter more precisely to allow only these element, classes, styles and attributes which you need. This solution is much better, because CKEditor will still remove a lot of crappy HTML which browsers produce when copying and pasting content, but it will not strip the content you want.
For example, you can extend the default CKEditor's configuration to accept all div classes:
config.extraAllowedContent = 'div(*)';
Or some Bootstrap stuff:
config.extraAllowedContent = 'div(col-md-*,container-fluid,row)';
Or you can allow description lists with optional dir attributes for dt and dd elements:
config.extraAllowedContent = 'dl; dt dd[dir]';
These were just very basic examples. You can write all kind of rules - requiring attributes, classes or styles, matching only special elements, matching all elements. You can also disallow stuff and totally redefine CKEditor's rules.
Read more about:
Content filtering in CKEditor – why do you need content filter.
Advanced Content Filter – in deep description of the filtering mechanism.
Allowed content rules – how to write allowed content rules.
I found a solution.
This turns off the filtering, it's working, but not a good idea...
config.allowedContent = true;
To play with a content string works fine for id, etc, but not for the class and style attributes, because you have () and {} for class and style filtering.
So my bet is for allowing any class in the editor is:
config.extraAllowedContent = '*(*)';
This allows any class and any inline style.
config.extraAllowedContent = '*(*);*{*}';
To allow only class="asdf1" and class="asdf2" for any tag:
config.extraAllowedContent = '*(asdf1,asdf2)';
(so you have to specify the classnames)
To allow only class="asdf" only for p tag:
config.extraAllowedContent = 'p(asdf)';
To allow id attribute for any tag:
config.extraAllowedContent = '*[id]';
etc etc
To allow style tag (<style type="text/css">...</style>):
config.extraAllowedContent = 'style';
To be a bit more complex:
config.extraAllowedContent = 'span;ul;li;table;td;style;*[id];*(*);*{*}';
Hope it's a better solution...
Edit: this answer is for those who use ckeditor module in drupal.
I found a solution which doesn't require modifying ckeditor js file.
this answer is copied from here. all credits should goes to original author.
Go to "Admin >> Configuration >> CKEditor"; under Profiles, choose your profile (e.g. Full).
Edit that profile, and on "Advanced Options >> Custom JavaScript configuration" add config.allowedContent = true;.
Don't forget to flush the cache under "Performance tab."
Since CKEditor v4.1, you can do this in config.js of CKEditor:
CKEDITOR.editorConfig = function( config ) {
config.extraAllowedContent = '*[id](*)'; // remove '[id]', if you don't want IDs for HTML tags
}
You can refer to the official documentation for the detailed syntax of Allowed Content Rules
if you're using ckeditor 4.x you can try
config.allowedContent = true;
if you're using ckeditor 3.x you may be having this issue.
try putting the following line in config.js
config.ignoreEmptyParagraph = false;
This is called ACF(Automatic Content Filter) in ckeditor.It remove all unnessary tag's What we are using in text content.Using this command in your config.js file should be turn off this ACK.
config.allowedContent = true;
Please refer to the official Advanced Content Filter guide and plugin integration tutorial.
You'll find much more than this about this powerful feature. Also see config.extraAllowedContent that seems suitable for your needs.
Following is the complete example for CKEDITOR 4.x :
HTML
<textarea name="post_content" id="post_content" class="form-control"></textarea>
SCRIPT
CKEDITOR.replace('post_content', {
allowedContent:true,
});
The above code will allow all tags in the editor.
For more Detail : CK EDITOR Allowed Content Rules
If you use Drupal AND the module called "WYSIWYG" with the CKEditor library, then the following workaround could be a solution. For me it works like a charm. I use CKEditor 4.4.5 and WYSIWYG 2.2 in Drupal 7.33. I found this workaround here: https://www.drupal.org/node/1956778.
Here it is:
I create a custom module and put the following code in the ".module" file:
<?php
/**
* Implements hook_wysiwyg_editor_settings_alter().
*/
function MYMODULE_wysiwyg_editor_settings_alter(&$settings, $context) {
if ($context['profile']->editor == 'ckeditor') {
$settings['allowedContent'] = TRUE;
}
}
?>
I hope this help other Drupal users.
I found that switching to use full html instead of filtered html (below the editor in the Text Format dropdown box) is what fixed this problem for me. Otherwise the style would disappear.
I would like to add this config.allowedContent = true; needs to be added to the ckeditor.config.js file not the config.js, config.js did nothing for me but adding it to the top area of ckeditor.config.js kept my div classes
Another option if using drupal is simply to add the css style that you want to use. that way it does not strip out the style or class name.
so in my case under the css tab in drupal 7 simply add something like
facebook=span.icon-facebook2
also check that font-styles button is enabled
I face same problem on chrome with ckeditor 4.7.1. Just disable pasteFilter on ckeditor instanceReady.This property disable all filter options of Advance Content Filter(ACF).
CKEDITOR.on('instanceReady', function (ev) {
ev.editor.pasteFilter.disabled = true;
});

Disable escape in Zend Form Element Submit

I can't disable escaping in a Zend_Form_Element_Submit, so when the label has special characters it won't display it's value..
This is my actual Zend Form piece of code:
$this->submit = new Zend_Form_Element_Submit('submit');
$this->submit->setLabel('Iniciar Sesión');
$this->submit->setIgnore(true);
$this->addElement($this->submit);
I've tried $this->submit->getDecorator('Label')->setOption('escape', false); but I obtain an "non-object" error (maybe submit isn't using the "Label" Decorator)..
I've also tried as suggested $this->submit->setAttrib('escape', false); but no text will be shown either.. Any idea? Thanks
Should be as simple as doing this:
$element->addDecorator('Label', аrray('escape'=>false));
Or see setEscape(). http://framework.zend.com/manual/1.12/en/zend.form.standardDecorators.html
Regarding failure to retrieve named decorator... Try getDecorators() Do you see 'label' in the results?
There is no Label decorator for submit form element by default (this is why you get the error).
The $this->submit->setLabel('Iniciar Sesión'); value goes to Zend_View_Helper_FormSubmit, which always does escaping and uses the label as a value.
The helper used by the Submit element escapes by default. Unlike with the label decorator, submit labels are included in a HTML attribute so they need to be escaped.
Your label - Iniciar Sesión - is a perfectly valid UTF-8 string, so the escaped version of it will be the same. If your label is not appearing then something else is going wrong. I'd guess that your page is being served using a charset that doesn't match what Zend View is using (UTF-8 by default).
View the page source to see what actually gets output - that might give you some more clues. Alternatively if the page this form is on is public, if you can provide a URL we might be able to spot the issue.
I ran into a similar issue. In my instance, I added both a label and a description to a text field element. This line of code allowed me to turn off the html escaping for the description attached to that field element:
$form->getElement('txtUPC')->getDecorator('description')->setOption('escape', false);
In my testing, the setEscape() was not recognized by the form elements or their decorators.
