\r
26 This sample page demonstrates the idea of Advanced Content Filter
\r
27 (<abbr title="Advanced Content Filter">ACF</abbr>), a sophisticated
\r
28 tool that takes control over what kind of data is accepted by the editor and what
\r
29 kind of output is produced.
\r
31 <h2>When and what is being filtered?</h2>
\r
33 <abbr title="Advanced Content Filter">ACF</abbr> controls
\r
34 <strong>every single source of data</strong> that comes to the editor.
\r
35 It process both HTML that is inserted manually (i.e. pasted by the user)
\r
36 and programmatically like:
\r
38 <pre class="samples">
\r
39 editor.setData( '<p>Hello world!</p>' );
\r
42 <abbr title="Advanced Content Filter">ACF</abbr> discards invalid,
\r
43 useless HTML tags and attributes so the editor remains "clean" during
\r
44 runtime. <abbr title="Advanced Content Filter">ACF</abbr> behaviour
\r
45 can be configured and adjusted for a particular case to prevent the
\r
46 output HTML (i.e. in CMS systems) from being polluted.
\r
48 This kind of filtering is a first, client-side line of defense
\r
49 against "<a href="http://en.wikipedia.org/wiki/Tag_soup">tag soups</a>",
\r
50 the tool that precisely restricts which tags, attributes and styles
\r
51 are allowed (desired). When properly configured, <abbr title="Advanced Content Filter">ACF</abbr>
\r
52 is an easy and fast way to produce a high-quality, intentionally filtered HTML.
\r
55 <h3>How to configure or disable ACF?</h3>
\r
57 Advanced Content Filter is enabled by default, working in "automatic mode", yet
\r
58 it provides a set of easy rules that allow adjusting filtering rules
\r
59 and disabling the entire feature when necessary. The config property
\r
60 responsible for this feature is <code><a class="samples"
\r
61 href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">config.allowedContent</a></code>.
\r
64 By "automatic mode" is meant that loaded plugins decide which kind
\r
65 of content is enabled and which is not. For example, if the link
\r
66 plugin is loaded it implies that <code><a></code> tag is
\r
67 automatically allowed. Each plugin is given a set
\r
68 of predefined <abbr title="Advanced Content Filter">ACF</abbr> rules
\r
69 that control the editor until <code><a class="samples"
\r
70 href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
\r
71 config.allowedContent</a></code>
\r
72 is defined manually.
\r
75 Let's assume our intention is to restrict the editor to accept (produce) <strong>paragraphs
\r
76 only: no attributes, no styles, no other tags</strong>.
\r
77 With <abbr title="Advanced Content Filter">ACF</abbr>
\r
78 this is very simple. Basically set <code><a class="samples"
\r
79 href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
\r
80 config.allowedContent</a></code> to <code>'p'</code>:
\r
82 <pre class="samples">
\r
83 var editor = CKEDITOR.replace( <em>textarea_id</em>, {
\r
84 <strong>allowedContent: 'p'</strong>
\r
88 Now try to play with allowed content:
\r
90 <pre class="samples">
\r
91 // Trying to insert disallowed tag and attribute.
\r
92 editor.setData( '<p <strong>style="color: red"</strong>>Hello <strong><em>world</em></strong>!</p>' );
\r
93 alert( editor.getData() );
\r
95 // Filtered data is returned.
\r
96 "<p>Hello world!</p>"
\r
99 What happened? Since <code>config.allowedContent: 'p'</code> is set the editor assumes
\r
100 that only plain <code><p></code> are accepted. Nothing more. This is why
\r
101 <code>style</code> attribute and <code><em></code> tag are gone. The same
\r
102 filtering would happen if we pasted disallowed HTML into this editor.
\r
105 This is just a small sample of what <abbr title="Advanced Content Filter">ACF</abbr>
\r
106 can do. To know more, please refer to the sample section below and
\r
107 <a href="http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter">the official Advanced Content Filter guide</a>.
\r
110 You may, of course, want CKEditor to avoid filtering of any kind.
\r
111 To get rid of <abbr title="Advanced Content Filter">ACF</abbr>,
\r
112 basically set <code><a class="samples"
\r
113 href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
\r
114 config.allowedContent</a></code> to <code>true</code> like this:
\r
116 <pre class="samples">
\r
117 CKEDITOR.replace( <em>textarea_id</em>, {
\r
118 <strong>allowedContent: true</strong>
\r
122 <h2>Beyond data flow: Features activation</h2>
\r
124 <abbr title="Advanced Content Filter">ACF</abbr> is far more than
\r
125 <abbr title="Input/Output">I/O</abbr> control: the entire
\r
126 <abbr title="User Interface">UI</abbr> of the editor is adjusted to what
\r
127 filters restrict. For example: if <code><a></code> tag is
\r
128 <strong>disallowed</strong>
\r
129 by <abbr title="Advanced Content Filter">ACF</abbr>,
\r
130 then accordingly <code>link</code> command, toolbar button and link dialog
\r
131 are also disabled. Editor is smart: it knows which features must be
\r
132 removed from the interface to match filtering rules.
\r
135 CKEditor can be far more specific. If <code><a></code> tag is
\r
136 <strong>allowed</strong> by filtering rules to be used but it is restricted
\r
137 to have only one attribute (<code>href</code>)
\r
138 <code>config.allowedContent = 'a[!href]'</code>, then
\r
139 "Target" tab of the link dialog is automatically disabled as <code>target</code>
\r
140 attribute isn't included in <abbr title="Advanced Content Filter">ACF</abbr> rules
\r
141 for <code><a></code>. This behaviour applies to dialog fields, context
\r
142 menus and toolbar buttons.
\r
145 <h2>Sample configurations</h2>
\r
147 There are several editor instances below that present different
\r
148 <abbr title="Advanced Content Filter">ACF</abbr> setups. <strong>All of them,
\r
149 except the inline instance, share the same HTML content</strong> to visualize
\r
150 how different filtering rules affect the same input data.
