API

With TimeZoneCalculator 2.00 and higher you can also realize a html select which displays for example the airtime of your internet radio station or your broadcasts in your users’ local time. Another possibility for the usage of the upcoming function is the integration of date, time and timezone information into your travelling blog.

Parameters can either be passed as an array or a URL query type string (e.g. “display=0&format=0”). Please note that WordPress parses all arguments as strings, thus booleans have to be 0 or 1 if used in query type strings whereas for arrays real booleans should be used. – Furthermore you have to break your timezones with \n : America/New_York;EST;EWT;New York, NY, US;New York, NY, US;0;0\nEurope/Vienna;;;sleep longer in winter;get up earlier to enjoy the sun;1;0 if you want to use different timezones in a query_string. In case you use an array, an array should also be used for the timezones.

function $timezonecalculator->output($params=array())

$params:

• query_time: any unix timestamp (where -1262304000 <= query_time <= 2145916800) or any English textual datetime description in the range of 1930-01-01 and 2038-01-01 which can be parsed with PHP’s strtotime function; default is set to current UTC

• query_timezone: origin-timezone of query_time; you can choose a PHP timezone_string; otherwise UTC will be used

• before_list: default <ul>

• after_list: default </ul>

• format_timezone: default <li><abbr title="%name">%abbreviation</abbr>: <span title="%name">%datetime</span></li>

• format_datetime: default Y-m-d H:i

• timezones: alternative timezones-array – each array entry has to be a string as described in the Manual Selection Section of the Admin Menu; default is the timezones-entries array which can be modified in the Admin Menu

• prefer_user_timezones: prefer user set timezones – if they exist – to global or function call timezones; default is false

• user_id: determines which user’s timezones should be used; not set as default -> use the timezones of the user who is currently logged in

• use_container: if set to true (default value), the current UTC is used as query_time and the same selected timezones and format is used as set in the admin menu, TimeZoneCalculator wraps the output in a html div with the class timezonecalculator-refreshable-output – the class timezonecalculator-output will be used for all other output; if you set use_container to false, no container div will be generated

• display: if you want to return the timezone-information (e.g. for storing in a variable) instead of echoing it with this function-call, set this to false; default setting is true

• format_container: This option can be used to format the div container with css. Please note, that it should only be used to provide individual formats in case the class-style itself cannot be changed.

• no_refresh: If set to true, TimeZoneCalculator will not produce any Ajax-Refresh-code, even if you have enabled the Ajax refresh in the admin menu.

Example for including a world-clock in your post-template (usually single.php or post.php in wp-content/themes) using WordPress the_date() function:

Find something similar to

the_date();

或者

the_time();

and replace it with

<?php $timezonecalculator->output(array('query_time' => the_date('U', '', '', false))); ?>

This outputs your selected timezones, whereas calculations are based on the timestamp of your post instead of using the current UTC.

How-to for shortcodes

General Example:

Enter the following text anywhere in a post or page to inform the clan when to meet up again:

let's meet tomorrow for a new challenge at:

[timezonecalculator_output query_time="tomorrow 8pm" query_timezone="Europe/Vienna" timezones="Europe/Vienna\nAsia/Bangkok"]

Available Shortcode:

timezonecalculator_output

Invokes $timezonecalculator->output($params). Please note that you have to use a query_string to select timezones which can be parsed into an associative array. – For example: America/New_York;EST;EWT;New York, NY, US;New York, NY, US;0;0\nEurope/Vienna;;;sleep longer in winter;get up earlier to enjoy the sun;1;0

How-To for filters

Available Filters:

timezonecalculator_defaults

In case you want to set the default parameters globally rather than handing them over on every function call, you can add the filter timezonecalculator_defaults in for example timezonecalculator.php or your own customization plugin (recommended).

Please note that parameters which you hand over to a function call ($timezonecalculator->output) will always override the defaults parameters, even if they have been set by a filter or in the admin menu.
