htaccess



The .htaccess-file is mainly separated in two parts

  1. some php/apache-settings
  2. rewrite rules for sefurls


The second part, the search engine friendly URLs and rewrite rules, are described in Rewrite Rules. See there for more information.

To activate

Tiki bundles a file named _htaccess. You should copy it to .htaccess

Alternatively, on Linux, you can make a symlink.

ln -s _htaccess .htaccess

PHP Settings

In some cases it is possible to overwrite some values from the php.ini file given by your ISP, by means of a file php.ini in the tiki root folder, or by means of some changes in the .htaccess file in the tiki root folder also. In this second case, place your special .htaccess file in the tiki root directory or just rename the _htaccess file given by Tiki to .htaccess an make your changes. You can visit tiki-phpinfo.php to check whether or not your changes where successful.

PHP Version

One of the critical setting is the PHP version that should correspond to the Tiki version you are using. (see http://doc.tiki.org/Requirements#PHP_" class="wiki wikinew text-danger tips">http://doc.tiki.org/Requirements#PHP_ ). It is possible in some case to have several PHP version installed on your host/server and you may need to set a different one than the default version used. You can change the value for a specific Tiki in the .htaccess file:

Values in .htaccess by default
# Option 2: PHP7
#AddType application/x-httpd-php7 .php
#AddHandler application/x-httpd-php7 .php


Some shared host may use a different setup and require a different path for the PHP version you need.
Please check with you server Admin or the company that manages it.

Exemple of specific shared host value
AddType x-httpd-php72 .php

PHP Memory Limit

Another important setting is the php memory limit. The maximum amount of memory a script may consume. On many shared hosts this variable is set to 64MB. Tiki runs fine with 64MB but depending on your special needs and options it is necessary to uncomment and increase this value to 128MB. (which is the default value on recent PHP versions)

# memory limit
php_value memory_limit 256M


Error Display

To display php errors on your display activate / uncomment this setting. Error output is very useful during development, but it could be very dangerous in production environments. Depending on the code which is triggering the error, sensitive information could potentially leak out of your application such as database usernames and passwords or worse.

# to activate the error display, uncomment the following line
php_flag display_errors on

# to set the error_reporting level, uncomment the following line. Values are explained here: http://www.php.net/manual/en/errorfunc.constants.php
 php_value error_reporting E_ALL


Execution Time

PHP uses a default script execution time of 30s before a script is terminated by the server. In some cases with huge wiki pages with many plugins it´s necessary to increase the execution time to 90s

# increase execution time (default value in php use to be 30, and in some cases of long wiki pages with many plugins it may take longer)
php_value max_execution_time = 90     ; Maximum execution time of each script, in seconds
php_value max_input_time = 90 ; Maximum amount of time each script may spend parsing request data


Maximum File and Post Size

The maximum allowed size for uploaded files and maximum size of POST data that PHP will accept.

# increase the maximum file size for uploads allowed by php for Tiki (default value in apache use to be 2M which is usually too low for pdf or documents with some images, screenshots, etc)
php_value upload_max_filesize 10M
php_value post_max_size 11M


Include Path

# In some cases you may see open_basedir warnings about Smarty accessing php files that it shouldn't
# The following line (uncommented) will reset the include path to use only Tiki's files which will solve this in most cases
php_value include_path "."

.htaccess content for 21.x

# $Id$ [This line is used to check that this configuration file is up
#  to date. Do not edit this line and leave it as the first line.]
#
# These are suggested configuration directives for use with Tiki.
# They enhance security and permit clean URLs.
# In your Tiki instance, visit tiki-admin.php?page=sefurl to make Tiki use clean URLs in generated links.
#
# The .htaccess file may be enabled in number of different ways (in order of the most to the least recommended):
# Option 1: Let the installer handle it.
# Option 2: Create a symbolic link from .htaccess to _htaccess. This will keep the configuration up-to-date.
# Option 3: Copy _htaccess to .htaccess. Note : Do not move (rename) _htaccess, it is required (used internally) by some Tiki features (like SEFURL).
# Option 4: Add the content of this file to your httpd.conf.
# The last two options should be repeated when the reference _htaccess file changes (when upgrading Tiki).
#
# DEVELOPERS: This configuration must be kept synchronized with the configuration for other Web servers.
# See http://dev.tiki.org/Operating+System+independence#Keep_web.config_and_.htaccess_synchronized

# -- Apache Error Handling -- #
# Tiki can catch some errors and deal with them by redirecting to a similar page, sending you to the
# search, etc. However, some errors do not reach Tiki and are only caught by Apache (ex.: filenameThatDoesntExist.php).
# To make Tiki handle errors caught by Apache, uncomment some of the following lines and adapt the page names.
# You must create the pages before trying to use them.
#ErrorDocument 404 /tiki-index.php?page=File+not+found
#ErrorDocument 500 /tiki-index.php?page=Server+error

# This is useful if you were using another Web application or static HTML and you want to avoid broken links.
#Redirect 301 /oldpage.html /tiki-index.php?page=newpage

# -- Force PHP Version -- #
# Tiki requires PHP5.6 - PHP7. If your host doesn't run one of these by default, it's possible that it can
# be activated by trying to enable it here.  Check with your host.
# Option 1: PHP5
#AddType application/x-httpd-php5 .php
#AddHandler application/x-httpd-php5 .php

# Option 2: PHP7
#AddType application/x-httpd-php7 .php
#AddHandler application/x-httpd-php7 .php

# -- Pass User/Object Information to Server Logs -- #
#SetEnv TIKI_HEADER_REPORT_ID tikiwiki
#SetEnv TIKI_HEADER_REPORT_USER on
#SetEnv TIKI_HEADER_REPORT_OBJECT on
#SetEnv TIKI_HEADER_REPORT_EVENTS on

# -- PHP Settings -- #
# If possible, it's better to change the following settings through your php.ini file, or through your webhosting control panel.
# Some web hosts will not allow you to change these setting through the .htaccess file.

# To activate the error display, uncomment the following line.
# Read more http://php.net/manual/en/errorfunc.configuration.php#ini.display-errors
#php_flag display_errors on

# To set the error_reporting level, uncomment the following line.
# Read more: http://php.net/manual/en/errorfunc.configuration.php#ini.error-reporting
#php_value error_reporting E_ALL

# Increase memory limit (default is 128M). Use this if you are getting blank pages and/or strange errors.
# Read more: http://php.net/manual/en/ini.core.php#ini.memory-limit
#php_value memory_limit 256M

# Increase execution time.
# Default value in Apache used to be 30, and in some cases of long wiki pages with many plugins it may take longer.
# Read more: http://php.net/manual/en/info.configuration.php#ini.max-execution-time
#php_value max_execution_time 90

# This sets the maximum time in seconds a script is allowed to parse input data, like POST and GET.
#php_value max_input_time 90

# Increase the maximum file size for uploads allowed by PHP.
# Default value in Apache used to be 2M which is usually too low for PDF or documents with some images, screenshots, etc.
# Read more: http://php.net/manual/en/ini.core.php#ini.upload-max-filesize
# Read more: http://php.net/manual/en/ini.core.php#ini.post-max-size
#php_value upload_max_filesize 10M
#php_value post_max_size 11M

# In some cases you may see open_basedir warnings about Smarty accessing PHP files that it shouldn't.
# The following line (uncommented) will reset the include path to use only Tiki's files which will solve this in most cases.
#php_value include_path "."

# Set a character set
#php_value default_charset utf-8

# Timezone
# Needed for dates and times to work properly in PHP.
# Option 1: recommended
#php_value date.timezone "America/New_York"

# Option 2: Set the apache environment variable
#SetEnv TZ America/New_York
