In this page, you'll learn how to include links in your Wiki pages, including links to other Wiki pages within the same Tiki site, links to an external Wiki site, and links to the Web.

Notes:

1. Tiki includes two options that modify the default link syntax: WikiWords and Autolink.
2. To enable WikiWords:
   • From the Administration: Wiki page, select the Features tab.
   • On the Features tab, enable the WikiWords option.
   
   If the WikiWords feature is disabled, you must use double parenthesis to create a Wiki page link.
3. To enable AutoLinks:
   • From the Administration: Text Area page, select the General Settings tab. In Tiki 4.x this is renamed to Editing & Plugins.
   • On the General Settings tab, in the Miscellaneous area, enable the AutoLinks option.
   
   If the AutoLinks features is disabled, you must use the square brackets to create a link to an external page.

When using the WikiWords option, Tiki will automatically detect Wiki page names and correctly format them as hyperlinks

The following are methods of creating links to Wiki pages

• TheWikiWay
  Two or more words are stuck together (no spaces, but accept - [dash] and _ [underscore]), and each is capitalized. You must enable the WikiWords option to use this mothod.
• ((The Wiki Way))
  Use double parentheses around the page name to Wiki page names that include spaces or when the WikiWords option is not enabled.
• (token-name(The Wiki Way))
  Use a token-name reference to link to wiki pages using a semantic link, a qualifier. Semantic links were introduced in Tiki 3.0 and have to be enabled separately. See Semantic Admin for more information. Trick: This can be also used to put a class on a link.

This table lists additional methods for creating links to wiki pages.

Help!

• If you save the page but see a question mark (?) after the page name, and you're sure the page exists, search for the page in the Search module to make sure you've typed the name correctly.
• When using WikiWords, Tiki will try to convert any word with odd capitalization into a Wiki link. Use double, reversed parentheses around a word to indicate that it should not be a wiki link — even when the WikiWords option is enabled. For example:
  ))WordStar(( will not become a link.

Semantic Wiki

Starting from version 3.0, Tiki supports semantic qualifiers on Wiki Links. To add a qualifier to the wiki link, the following syntax must be used:

(qualifier-name(The Wiki Way))

• Qualifiers may contain lowecase letters (a-z) and dashes.
• The qualifier name will be added as a CSS class on the link to customize the display.
• Semantic relationships can be managed by administrators from Semantic Admin. Relationships can be viewed from Module semantic_links.

For all other types of pages within a Tiki site, a shortened address can be used with square brackets. Here are some examples:

Note: Use [[foo] to display [foo]

To create a link to an attachment to a wiki page, use PluginAttach or PluginFile. If you'd like for an image to act as a link, so that clicking on the image takes you to another page, see the link image tab under Parameters on the PluginImg page.

Link to an image in a popup

[display37|Click here to see the image in a popup|shadowbox]

Click here to see the image in a popup

If PluginTabs is used on a page, the following syntax can be used to display specific tab within that page without refreshing the page:

Tab 2

Tab 2

Here are the key parts of the syntax:

• tikitabs(2) (with version 7.0) or tikitabs(2,4,1) (before 7.0):
  • 2 means the second tab will be displayed when the link is clicked
  • 4 means there are 4 tabs in total (before 7.0)
  • Always use 1 for the third number (before 7.0)
• href="#tab2" - this can be any text, except that it should start with a #
• Tab 2 - this will be the text that shows as a link

Here's an example:
Tab 2

First tab

Second tab

Fourth tab

Here are some plugins that provide navigational links:

• PluginAname - creates an anchor on a wiki page.
• PluginAlink - links to an anchor in a wiki page. Use in conjunction with PluginAname
• PluginBack - creates a link to go back one page
• PluginBacklinks - shows all the pages that link to a page
• PluginRedirect - causes links to a page to redirect to another page

If the site administrator has enabled this option, shortened links to pages in an external Wiki can be created. You'll need to know the short name that the administrator has set up to use this feature - the information may be documented on the site in a TikiWiki Manual of Style or you can ask your administrator. See External Wikis for a complete explanation as well as the shortcut links for external wikis that have been defined on this site (under the heading List external wiki references).

You can link to any page on the Web that has a valid URL. By default, Tiki creates a local cache of the page so that it will be available even if the remote Web site is down. Here are some examples of the syntax:

See the Quick Reference section above for how to set the AutoLinks administrative option. In addition, two more administrative options related to external links:

• To open external links in new window:
  Go to Setting > Control Panels > Editing and Plugins > General Settings > External links and images and check Open external links in new window and click "Change Preferences." If this feature is disabled, external links open in the existing browser window.
  
  
• To disable the external link icon ( ):
  Go to Setting > Control Panels > Editing and Plugins > General Settings > External links and images and uncheck External link icon then click "Change Preferences." With this disabled, the icon ( ) will no longer appear at the end of any external links. Keeping it enabled allows users to know when they are being directed to another site.

Important: If you are linking to a PDF file, a multimedia file, or any file other than an HTML page, please include the nocache directive, as in the following examples:

• [http://www.somesite.org/docs/chapter1.pdf |nocache]
• [http://www.somesite.org/docs/chapter1.pdf|Chapter One|nocache]

Help!

• If the link doesn't work, try copying the URL into your browser window, and click Enter. If the page exists, go back and check your typing. Chances are you'll find that you've made a typing error. Did you type both brackets correctly?

You need to add the extra text "|box" (or maybe "|shadowbox" in earlier releases, if box doesn't work for you) after the label of your external link. You can also add some params, if needed, for the external resource, followed by semicolons.

Example1
Show a YouTube video in semitransparent popup (colorbox) in full screen size.

[http://www.youtube.com/v/KBewVCducWw&autoplay=1|You Tube video in their flash player|box]

Which would produce:
You Tube video in their flash player

Example2
Show a YouTube video in semitransparent popup (colorbox) but with defined smaller size than full screen:

[http://www.youtube.com/v/KBewVCducWw&autoplay=1|You Tube video in their flash player|shadowbox;width=405;height=340;]

Which would produce:
You Tube video in their flash player

To link to an Email Address, enclose the mailto URL within square brackets, as in the following examples:

• Type this: [mailto:johndoe@example.org]  
  To get this: mailto:johndoe@example.org

• Type this: [mailto:johndoe@example.org | John Doe]
  To get this: John Doe

• to enter a text between brackets. Put 2 open brackets, the text and one closing brackets like this [[xxxx] that will output [xxxx]

Tiki has a built-in class (called tikihelp) that allows you to create a formatted tooltip for a link as follows:

The following syntax:

{HTML()}Home Page{HTML}

Would produce on this site:

Home Page

Mouse over the above link to see the formatted tooltip. Here's what's important for the tooltip to appear like this:

• JQuery must be enabled
• Set class="tikihelp"
• First part of the title before the colon is the heading of the tooltip and the text after the colon is the body.

Whenever Tiki finds a link to an external site in a Wiki page the link is cached in the Tiki cache, this allows the Wiki users to visit the page even if the site is offline or the page is removed or changed.

When you make a link in a Wiki page, you can choose to request that it not be cached. This is done by adding the phrase after the link description between the square brackets.
Admins, see Link Cache.
