Archive-Pro-Matic Advanced Category Archives

Building on the new block-style archive described in the last post, we now try with categories:

All Categories:

[archives type="monthly" taxonomy="category" sub_options="block" tag="div" sub_ul_class="my_slim_ul" li_class="block_archive_item" limit="10"/]

Single Category

[archives type="monthly" taxonomy="category" term="archive-pro-matic" sub_options="block" tag="div" sub_ul_class="my_slim_ul" li_class="block_archive_item" limit="10"/]

or use the cat attribute:

[archives type="monthly" cat="special1-posts" sub_options="block" tag="div" sub_ul_class="my_slim_ul" li_class="block_archive_item" limit="10"/]

or use the category attribute (alias for cat):

[archives type="monthly" category="special1-posts" sub_options="block" tag="div" sub_ul_class="my_slim_ul" li_class="block_archive_item" limit="10"/]

Multiple Categories

For an archive of multiple categories, the cat_id attribute must be used:

[archives type="monthly" cat_id="55,43" sub_options="block" tag="div" sub_ul_class="my_slim_ul" li_class="block_archive_item" limit="10"/]

Tidal Chart for Leith

How to caculate a countdown to the next high and low tide.

First, there is a nice plugin called Tides Today UK and Ireland tide times that allows tidal charts to be displayed using a Sidebar Widget or a shortcode. For example:

[[tide_times days=1 title="Tide times for Leith" location="leith"]These are today's tides for Leith[/tide_times]]

That outputs a tidy forecast like so:

[tide_times days=1 title=”Tide times for Leith” location=”leith”]These are today’s tides for Leith[/tide_times]

The shortcode references the authors own web-service api that returns a JSON encoded dataset. Here is the dataset for Leith. However, the plugin author clearly (if not threateningly) states:

You may not use the data provided by the API for anything other than displaying tide information on your website by the
means provided by this plugin.

…Failure to comply with any of the conditions outlined here or as outlined in the Tides Today Terms and conditions will result in legal action being taken.

In the words of Al Swearengen:

Not a tone to get a deal done.

Even though the datasource provide is from the UK Hydrographic Office:

All data is provided by the UK Hydrographic Office and is provided under license. Crown Copyright 2016.

So we might need to find our own, tax-funded, public, non-threatening api to get our tidal info from, for example:
even better:

The NOAA api looks quite promising… but it’s only for North America. So we move on to Worworldtides api which provides 1000 free calls per month. So far that is a winner. Now let’s take a look at The National Tidal and Sea Level Facility. It seems it only serves the UK and Ireland. Here is Leith.

Collapse-O/Pro-Matic Highlander Must Be One

As of Collapse-O-Matic version 1.7.2 and Collapse-Pro-Matic version 1.3.2 we have added the ability to force one element to stay open in a highlander grouping. Simply add the class must-be-one to all the triggers in a highlander group using the trigclass attribute like so:


[expand title="Monkeys" rel="animal-highlander" trigclass="must-be-one"]...[/expand]
[expand title="Donkeys" rel="animal-highlander" trigclass="must-be-one"]...[/expand]
[expand title="Ninjas" rel="animal-highlander" trigclass="must-be-one"]...[/expand]


A monkey is a primate of the Haplorrhini suborder and simian infraorder, either an Old World monkey or a New World monkey, but excluding apes and humans. There are about 260 known living species of monkey. Many are arboreal, although there are species that live primarily on the ground, such as baboons. Monkeys are generally considered to be intelligent. Unlike apes, monkeys usually have tails. Tailless monkeys may be called “apes”, incorrectly according to modern usage; thus the tailless Barbary macaque is called the “Barbary ape”.

The donkey or ass, Equus africanus asinus,[1][2] is a domesticated member of the Equidae or horse family. The wild ancestor of the donkey is the African wild ass, E. africanus. The donkey has been used as a working animal for at least 5000 years. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. Working donkeys are often associated with those living at or below subsistence levels. Small numbers of donkeys are kept for breeding or as pets in developed countries.

A ninja (忍者?) or shinobi (忍び?) was a covert agent or mercenary in feudal Japan who specialized in unorthodox warfare. The functions of the ninja included espionage, sabotage, infiltration, and assassination, and open combat in certain situations.[1] Their covert methods of waging war contrasted the ninja with the samurai, who observed strict rules about honor and combat.[2] The shinobi proper, a specially trained group of spies and mercenaries, appeared in the Sengoku or “warring states” period, in the 15th century,[3] but antecedents may have existed in the 14th century,[4] and possibly even in the 12th century (Heian or early Kamakura era).[5][6]
