[archived] eoi_location: latitude, longitude

Hi,

This is my first day toying with Textpattern. I only noticed today that it’s been released under the terms of the free GPL license (much respect Dean!) and thought I’d give it a wirl. For starters, I thought I’d port a plugin I made for some other blogware to TXP.

blub, blub, blub… (sound of me going down the deep end)

Here’s what I’m trying to do: Make a plugin for TXP so people can enter a latitude and longitude (into a custom field) for any post and have a heap of cool geo-location features on their site like links to MapQuest, GeoURL tags, and a list of other articles ordered by geographic proximity to the current one.

Here’s where I’m stuck: I can’t find the source code to any of the TXP plugins which I think might help me learn how to access custom fields and the database. Hints anyone?

here’s some code that might help you with custom fields.

<pre> if (is_array($atts)) extract($atts); global $thisarticle; global $txpac;

//Get extra fields from db $id = $thisarticle[“thisid”]; $query = safe_rows(“*”, “textpattern”,“id=’$id’”);

//Shove values + labels into simple arrays for($i = 1;$i <= 10;$i++) { $name = “custom_”.$i.”_set”; $fields[$i][“label”] = $txpac[$name]; $vname = “custom_”.$i; $fields[$i][“value”] = $query⁰[$vname]; }
</pre>

eventually it’ll be a plugin in itself, but when I get the time.

Thanks tmacwrig!

I take it that the bit which didn’t make it through textile properly above was supposed to be square brackets open, zero, square brackets close.

But I can’t get it to work. Indeed… I can’t even get my plugin to return a simple “hello world” string (simply using an echo command). :-(

I’m finding this compiling business for plugins a real drag. Anyone got the source code to a simple plugin which I can learn from? :-)

Have you already installed a plugin? If so, go to the code (admin/plugins) and add the following:
function sdr_echo ($atts) {
return echo “Hello World!”;
}

Now add the <txp:sdr_echo /> tag to a page. This should output the string at your chosen loation.

http://eoin.free.fr/media/eoi_location.txt

Plugin name: eoi_location

Version: 0.1b

Adds geographic location features to Textpattern, as found in WordPress, and a similar plugin I did for NucleusCMS. Name one of your custom fields ‘latitude, longitude’ and you can enter a geographic location for any article using decimal notation (e.g. “xx.xxxx, yy.yyyy”). Then add the tag txp:eoi_location with any of the attributes below to have some fun.

Attributes:
customid – Enter the number of the custom field you are using for geographic coordinates (default is 1).
format – Enter any of these formats to have your coordinates come that way (like format=raw):
- raw – Exactly as it appears in the custom field (default).
- lat – Latitude as it appears in the custom field.
- lon – Longitude as it appears in the custom field.
- multimap – URL to use in a hyperlink to multimap.com.
- mapquest – URL to use in a hyperlink to mapquest.com.
- acmemap – URL to use in a hyperlink to acme.com’s mapper program (US only).

Example:
txp:eoi_location customid=“3” format=“multimap” could be used inside an “a href” HTML tag like this: a href=“txp:eoi_location customid=“3” format=“multimap” “Show in MultiMap/a

To do…
I want to add distance calculation, proximity searching, and other features like that. I also want allow input and output in DMS format too.
