(PHP) Force Geo Mashup to use a different home URL (add a slash)

Sun, 21 Oct 2012 02:45:24 GMT

Some hosting configurations do uncontrollable redirects and other oddities that play havoc with Geo Mashup maps. Most commonly the home URL redirects improperly unless a slash is added at the end. This code attempts to add the slash just for Geo Mashup. Put it in a theme functions.php or in mu-plugins.

(JavaScript) WordPress Geo Mashup Mapstraction Custom Markers

Fri, 20 Apr 2012 10:23:34 GMT

Some common custom javascript for customizing geo mashup map markers for Mapstraction map providers (any other than Google v2). The marker images used are 24 x 24 pixels, anchored at the bottom center, with no shadow. You'd put images in `wp_content/plugins/geo-mashup-custom/images` to work with this snippet.

(PHP) Load a javascript library (MarkerWithLabel) in a Geo Mashup map frame template

Tue, 03 Apr 2012 05:03:36 GMT

This is very close to the default map frame template that comes with Geo Mashup, but it registers and queues the external library.

(JavaScript) Load KML attachments for all geo mashup map markers

Sun, 01 Apr 2012 10:43:07 GMT

By default KML is only loaded for a selected marker. This bit of [custom javascript](http://code.google.com/p/wordpress-geo-mashup/wiki/Documentation#Custom_JavaScript) will load it for all markers.

(HTML) Fix for Addthis menu appearing at page top

Fri, 25 Mar 2011 04:51:30 GMT

If you use hidden text spans inside link buttons instead of an image tag, addthis menus seem to attach to the page top instead of the link. For some reason a strong tag used the same way works.

(PHP) Geo Mashup global map of the current category

Fri, 19 Nov 2010 03:22:59 GMT

This code would go in a category template, outside the loop. In a more general template, you'd want to put it inside a check for `is_category()`.

(PHP) Geo Mashup post query contextual map

Wed, 28 Jul 2010 02:51:41 GMT

Geo Mashup contextual maps display the results of a WordPress query, so they can be very useful in combination with the WordPress `query_posts` function. This example maps post with an example tag, but any call to `query_posts` could be substituted. This is code that would go in a WordPress template.

(PHP) Conditional Geo Mashup map template code

Wed, 10 Mar 2010 15:26:24 GMT

This template code will work only in the WordPress Loop to include a map if the Geo Mashup plugin is active and the current post has a location.

(PHP) Global Geo Mashup map centered on current post

Thu, 11 Feb 2010 11:53:59 GMT

Use this code in a WordPress template with the Geo Mashup plugin (see URL) to include a global map within a post or page, centered on that post or page's location, with marker highlighted.

(jQuery) Toggle next element on click

Fri, 13 Nov 2009 12:47:04 GMT

Make elements with the "toggle-next" class show/hide the following element when clicked.

(PHP) WordPress is_child_of: Is this a child of page x?

Thu, 08 Oct 2009 15:25:09 GMT

This makes template code that applies to children of a particular page much more readable, especially if you can use a page path instead of an ID: `if ( is_child_of( 'topic/subtopic' ) ) :`.

(JavaScript) Disable and enable a text input in Firefox

Wed, 02 Sep 2009 12:49:15 GMT

I just noticed in Firefox 3.5.2 that setting `disabled = true` for a focused text input seems to make it impossible to re-focus after setting `disabled = false`. The solution is to blur it before disabling.

(jQuery) Encode HTML entities

Fri, 28 Aug 2009 14:46:57 GMT

Found at the source link - stealing and indexing :)

(jQuery) Get the selected value from a select box

Fri, 28 Aug 2009 08:44:14 GMT

It's not obvious from the jQuery documentation that `val()` will work to get the currently selected value of a select box (in 1.3.2 at least).

(PHP) WordPress: in subcatory?

Wed, 26 Aug 2009 15:15:48 GMT

Usually use in a template with `in_category()`, like `if ( in_category( 3 ) || in_subcategory( 3 ) ) { ...`. Tested in WP 2.8.4.

(jQuery) Simple tabs with jQuery Core (not jQuery UI)

Wed, 19 Aug 2009 13:02:49 GMT

Sometimes I want simple tabs without all the packaging of jQuery UI with a theme. This does the job with just jQuery 1.2.6, and should work with later versions.

(PHP) WordPress: Get the root page ID

Mon, 17 Aug 2009 17:49:20 GMT

Get the ID of the root (oldest ancestor, parent without parents) page relative to the current page in a WordPress page template. Can be helpful for use with wp\_list\_pages() to create navigation markup.

(jQuery) jQuery: select first and/or last list items

Mon, 17 Aug 2009 17:14:01 GMT

Select the first and last item in an unordered list. As an example, I add a CSS class to each. In WordPress, it's not so easy to get wp\_list\_pages() to generate these classes. jQuery provides an easy out for javascript-enabled clients.

(PHP) Wordpress: Does a page have children?

Mon, 17 Aug 2009 11:20:03 GMT

There's no has\_children() function in WP 2.8.4, but get\_children() returns false if the post/page has no children, so it can serve the same purpose in a page template. Outside a page template you'd have to add a global declaration for the $post variable.
