About

Below, we will document some little template Tips. Typically show content depending on something. Can be done directly in templates/*.tpl files or in Admin > Look & Feel.

Custom CSS and JS

Starting in Tiki5, in Admin > Look & Feel (tiki-admin.php?page=look) > Miscellaneous, there is a Custom Code section to add custom CSS and JavaScript.

You can create styles/custom.js or styles/yourtheme/custom.js and that should get included automatically. You may need to empty your Tiki cache.

Change size of subtitle

custom CSS
Copy to clipboard
#sitesubtitle { font-size: 24px; }

Help - I broke my theme

Apparently, a problem with my custom theme is preventing me from accessing my site normally.

Reset the theme "manually": If you can't access the admin pages to set your site's theme back to one that is known to work, you can reset the theme from the back end, so to speak.

Database method: Use phpMyAdmin on your server to access your Tiki database. In the table "tiki_preferences", find the row for "site_style". Edit this row by replacing the custom theme name with a standard theme, such as thenews.css.

FTP method (easier): Using your FTP client, go to the styles directory of your Tiki installation and rename the theme currently set as the site theme, such as by changing its ".css" file extension to ".txt". Tiki will revert to the default. Log in using the default theme and fix what is wrong. Also clear the site caches.

When trying out a new theme, it is much better to use the "switch theme" module to select it. Don't make a new and untried theme the site theme without first trying it out from the switch-theme module.

I am stuck in a theme

To change themes, you can point your browser to a non faulty theme:

  1. Point your browser to: tiki-switch_theme.php?theme=fivealive.css
  2. Then, also check to Clear the cache with tiki-admin_system.php?do=all

If anything doesn't change

For some unknown reason the theme doesn't change. Look directly in the database in 'tiki_preferences' look at:

Copy to clipboard
UPDATE `tiki_preferences` SET `value` = 'fivealive.css' WHERE `tiki_preferences`.`name` = 'style';

Howto

Escaping variables used in Smarty

When modifying templates, it is important to check that variables that display output on screen be escaped except in certain circumstances, to act as a safeguard agains unfiltered user input being displayed back on the page. The question is when to escape and when not to escape? See http://www.smarty.net/docs/en/language.modifier.escape.tpl

  • If the output of your template will be used in another template as a variable that will be escaped there, then there is no need to escape it the first time as it will lead to double escaping.
  • If the variable is expected to possibly contain HTML, then it cannot be escaped otherwise the HTML will be displayed as text on screen. In those cases, it is the responsibility of the code that generated the HTML (e.g. the wiki parser to ensure that the HTML output is filtered), and the code of the input user interface to perform filtering in case any user enters any HTML - only trusted users should be allowed to enter any HTML).
  • If the variable is used for redisplaying what the user entered in an input text field, then it cannot be escaped otherwise it will lead to double escaping the next time the user submits the form.
  • In all other cases, the variable should be escaped using the escape variable.

Adding a print button only if current page is a wiki page

Copy to clipboard
{if $page neq ''} <a title="{tr}Print{/tr}" href="tiki-print.php?page={$page|escape:"url"}"> <img src="https://themes.tiki.org/show_image.php?id=54"/>{tr}Print{/tr} </a> {/if}

Adding some HTML (ex.: a logo) to the print version of wiki pages

Admin - Look and Feel - Customization - HTML
Copy to clipboard
{if $SCRIPT_NAME eq '/tiki-print.php'} <img src="http://themes.tiki.org/show_image.php?id=53" alt="Site Logo" style="border: none"> {/if}

Adding a "Hello John" indication

Copy to clipboard
{if $user} Hello {$user} {/if}

Adding content only for a group

In content

In a template

Copy to clipboard
{if $group eq "Admins"} You are a member of the group {$group} {/if}

Adding content only for a permission

Copy to clipboard
{if $tiki_p_admin eq 'y'} You have full admin rights {/if}

Adding content only for a preference

Copy to clipboard
{if $prefs.feature_wiki eq "y"} The Wiki feature is on {/if}

Dislay the value of a Tiki preference in content

https://doc.tiki.org/PluginSmarty#Display_a_Tiki_preference_in_content_such_as_a_wiki_page

Adding content only for a category

Copy to clipboard
{if isset($objectCategoryIds) and in_array(257, $objectCategoryIds)} show this {/if}

Display content conditional to current language

Copy to clipboard
{if $prefs.language eq "fr"} <a href="accueil"> {elseif $prefs.language eq "es"} <a href="inicio"> {else} <a href="tiki-index.php"> {/if}{tr}Home{/tr}</a>


This is an Smarty block to display only if language matches.
It's one quick hack like PluginLang, but to use in modules and templates.

Example:
{translation lang="en"}Hello{/translation}
{translation lang="pt-br"}Olá{/translation}

If the current language is en, Hello will be displayed. If it is pt-br, Olá.

To make users switch language, you can add Module switch_lang or hard code some links such as:

Copy to clipboard
{if $prefs.language eq "fr"} <a href="tiki-switch_lang.php?language=fr">-English-</a> -Français- <a href="tiki-switch_lang.php?language=es">-Español-</a> {elseif $prefs.language eq "es"} <a href="tiki-switch_lang.php?language=en">-English-</a> <a href="tiki-switch_lang.php?language=fr">-Français-</a> -Español- {else} -English- <a href="tiki-switch_lang.php?language=fr">-Français-</a> <a href="tiki-switch_lang.php?language=es">-Español-</a> {/if}

How to know where something is in a template?

Admin > Look & Feel > Add HTML comment at start and end of each Smarty template (TPL). Then, clear your template cache (tiki-admin_system.php?do=templates_c)

The system name for this feature is "log_tpl". Then, when you "view source" with your browser, you will see which template was used to create it.

Make sure to turn off once you go into production, or else your email notifications will also have a note!

How do I know which template to modify to affect the look & feel of a specific URL?

Generally, if the page name is tiki-abc.php, look templates/tiki-abc.tpl

If you can't find it:

  1. Activate the "Smarty Template usage indicator" in tiki-admin.php
  2. You need to clear the template cache (tiki-admin_system.php?do=templates_c) for this change to be taken into effect.
  3. You can then check the final page source to see what code is produced by what Smarty template file. (View HTML source from your browser)


As indicated on that page, "Use only for development, not in production because these warnings are added to emails as well, and visible to the users"

How do I change the email messages?

Look in: templates/mail/

Ex.: templates/mail/share_subject.tpl contains

Copy to clipboard
{tr}A friend sends you a link from: {/tr} {$mail_site}


You have three options:

  1. Modify that file
    • If you update your site via FTP, this will break at the next upgrade
  2. Copy that file into your custom theme and modify it there
    • ex.: templates/styles/mycustomestylehere/mail/share_subject.tpl
    • Thus, when you upgrade via FTP, this file will remain. However, you should check for changes in the original file
  3. Use the Interface Translation features of Tiki.
    • You should do this for any language you use. Even if your site is only in English, you can use the English to English translation file to have custom strings and keep your Tiki code untouched and make upgrades easier (pretty nifty if you ask me!)


After any file change, make sure to empty all your cache

How to show content just when in certain pages/features. Ex.: tiki-searchresults.php

So if you want to modify tiki-searchresults.php, you find templates/tiki-searchresults.tpl

For the container

templates/tiki.tpl is the master container.

Say you want to affect the master container based on the current page, you can do

Copy to clipboard
{if $mid eq "tiki-searchresults.tpl"} bla bla {/if}

Add a Banner for each Blog, like a personal logo header

add the following code in Site Ads and Banners Content:in Site Ads and Banners section in Administration menu. http://www.yoursite.com/tiki-admin.php?page=ads
this exemple shown a banner set in zone 'ZoneName' if the blogid #2 is active.

Copy to clipboard
{if $blogId eq '2'} {banner zone=ZoneName} {/if}

How to force switch Theme for Anonymous

You could use the Group Theme feature but it seems broken currently in Tiki 5 so here's a workaround using JavaScript code in Admin > Look & Feel > General Layout > Custom HTML <head> Content ("Registered users can switch themes" - preference name change_theme - must be enabled):

Copy to clipboard
{if !$user and $prefs.style ne "jqui.css"}<script type="text/javascript"> <!-- window.location = "tiki-switch_theme.php?theme=jqui.css" //--> </script>{/if}

How to make a page full width (no side columns but header and body): Liquid-width

Web pages can be liquid-width (using 100% of the browser viewport from left to right) or fixed-width (using some part of the total width). Bootstrap uses a container class div to limit the width of the web page's content to 1170px (default) in the center of the screen. But sometimes, for the graphic design or other reason, we want to have one or more page sections that don't have this width limitation.

See Liquid-width section in page

Add wiki syntax in Custom code text areas of Look & Feel

Copy to clipboard
{wiki}{literal} ::My __wiki__ code:: {/literal}{/wiki}


This works until Tiki6, because starting in Tiki7, all the zones are now drag & drop modules

Add JavaScript tracking code

See Piwik example.

Add your own PHP code

You can add PHP to Smarty using the php smarty tag, but for this to work, you need to deactivate the Smarty Security (which is on by default). A safer and better way is to Create your own Smarty plugin.

Add Post-It Notes

See Custom Code HowTo - Post-It Notes

Add a top-level menu

Until Tiki6

tiki-admin.php?page=look -> General Layout options -> Secondary site menu custom code

replace 47 with your actual menu ID
Copy to clipboard
{menu id=47 css=y type=horiz}

Tiki7 and above

This is easier now, and you can use Module menu, which you can drag & drop (and double click to edit parameters) at tiki-admin_modules.php

You need to set the params to the module such as nobox=y, etc...

Timed content

Dynamic content

Show the content without columns

point your browser like this example: tiki-index_p.php?page=i18n

Or use PluginAppFrame

Add a wiki page in module

How to Add Custom jQuery Code Using the Custom Code Textareas

Debug

Put in a template or in Look & Feel custom code to have a popup with information on all the variables, at each page refresh.

Copy to clipboard
{debug}


To avoid driving your users mad 😊

Copy to clipboard
{if $user eq 'admin'} {debug} {/if}

Categories used in templates

Admin -> Category -> Categories used in templates (TPL)
(categories_used_in_tpl)

How to use? Something like
http://doc.tiki.org/Category+Admin#Using_the_current_object_categories_in_a_tpl
another

To determine if an object is categorized, use:

Copy to clipboard
{if !empty($objectCategoryIds)} NOT categorized {else} AM categorized {/if}

Show or hide modules by category

This is a new native feature in Tiki8. Just admin any module and indicate when to hide/show as you would edit any module param...

Section

Copy to clipboard
{if $section eq "blogs"} text shown just when in one of the blog pages {/if}

Perspective

The current perspective ID is not available to the templates. However, you can simply use the value of something that was overridden in this template. This could be in one of the Site identity fields.

To change the menu depending on the Site title
Copy to clipboard
{if $prefs.sitetitle eq "Workspace Sales"} {phplayers id=45 type=horiz css=y} {else} {phplayers id=47 type=horiz css=y} {/if}

Variables

Clearing cache

Improve communication for planned maintenance


If your site changes hosts, you may have time to plan a nice message on the maintenance page of the old host. The maintenance mode only permits a short sentence, as the maintenance page should work even if the database is unavailable.

This is the part of tiki-error_simple.php you are looking for.

Section of tiki-error_simple.php
Copy to clipboard
echo '</p> <form name="loginbox" action="tiki-login.php?page=tikiIndex" method="post">

Note that all is into a <pre> tag, so don't forget the line breaks. Also, handle single quotes with care.
new example message
Copy to clipboard
echo '</p> The site xxxxxx.xxx is being transferred between servers between 19:30 and ca. 21:00 GMT today, 29 December 2011. Access during this time may be interrupted for short periods. No editing of pages and no posting will be possible during this time. While the new location is being propagated over the Internet (can take hours) you can <a href="http://new-xxxx.xxx">reach the site here.</a> <form name="loginbox" action="tiki-login.php?page=tikiIndex" method="post">
