  1. Remove any files already added form the working directory. For example:

    $ git rm -f *dwsync.xml

  2. set up your a global git ignore file

    create a gitignore file in your home directory. eg:

    $ printf "dwsync.xml\nThumbs.db\n" >> ~/.gitignore

    using git config add this to you git prefs

    $ git config --global core.excludesfile ~/.gitignore

For repos that may be worked on by multiple users you should also create this file at the root of your working directory.

If you swap your WP database between a development and production server at all regularly and don’t fancy editing your site URL and WordPress URL in the wp-options table each time (either directly or via the WP admin interface)… you can hard code it into the wp-config.php file! Tie this together with WordPress ability to keep this config file out of harms way in a directory above your WP install (ie out of your public_html directory) and you have an easy hands free file sync operation too.

Just add these two lines of code into wp-config.php:

// hardcoding the domain
define("WP_SITEURL","http://www.mysite.com");
define("WP_HOME","http://www.mysite.com");

BTW – note the lack of trailing slashes on the URLs

Usual stuff but well written without either speeding or jabbering.

There’s a nice overview of Custom Menus, Multisite, Custom Post Formats, Custom Post types and Custom Taxonomies.

WP Custom Heaven

One thing I’d never heard of before was the new ability in WordPress 3.x to enable custom background images to any post. Just add the following to your functions.php file:

add_custom_background();

. Look up the codex for more. Aparently this allows admin users to change background image properties (as CSS) from within the appearance menu. http://codex.wordpress.org/Function_Reference/add_custom_background. Having not tried this – but I think its limited to a global preference per install – so of limited use to theme developers.

Anyway nice stuff Jeff Starr at .Net …

Basic stuff: get value from URL querystring with PHP http://www.lazydada.com/2011-07-11/basic-get-value-from-url-querystring-with-php/?utm_source=rss&utm_medium=rss&utm_campaign=basic-get-value-from-url-querystring-with-php http://www.lazydada.com/2011-07-11/basic-get-value-from-url-querystring-with-php/#comments Mon, 11 Jul 2011 09:14:50 +0000 admin http://www.lazydada.com/?p=934 As I’m still an idiot when it comes to media queries and mobile devices and can pass this stuff on to other folks – but needed to give myself and the interested parties a visual representation of how different sized graphics will be delivered to different mobile devices… I was after a simple ‘switch’ that would allow a single wedge of HTML to render according to a variable.

The example here goes along the lines of http://example.com?width=340 where the width has a few values it accepts or will default to a preset size…

This variable can then get passed around in the PHP file to set image dimaensions CSS etc…

<?php
function getUrlStringValue($urlStringName, $returnIfNotSet) {    if(isset($_GET[$urlStringName]) && $_GET[$urlStringName] != "")      return $_GET[$urlStringName];    else      return $returnIfNotSet;  }
$width = getUrlStringValue("width", "480");

You want a simple script to redirect to a different page if te referrer is such and such. In the following example the two referral page options ( foo.html and bar.html ) are separated with the double pipe (the ‘or’ bit)… 

<script type="text/javascript">
if (document.referrer == ("http://example.com/foo.html" || "http://example.com/bar.html"))
      location.href = "foobar.html";
</script>

If this had been around a year ago ‘d have avoided having to craft this php counting system for a custom WordPress loop.

Want to get something in your theme to work with data from a particular page or post – but don’t know for sure what that post’s ID is?

A. Try this in your functions.php file:

$my_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = 'myPost'");

…then you can then pass a variable about in your theme’s templates.

This doesn’t work in WordPress theme parts. It’s easy to overcome though… you just need to recall the variable first…

somewhere in functions.php

 $my_var = "xyz"

Now i can do this somewhere in header.php

<?php global $myVar ;  ?>
<?php echo $myVar; ?>

Got a theme that needs two different excerpt lengths?

A. Found here: set the standard, longer excerpt as normal in the functions.php file and the override locally using this code:

<?php echo substr( get_the_excerpt(), 0, strrpos( substr( get_the_excerpt(), 0, 75), ' ' ) ); ?>

I mostly use git to track changes (very useful to check on what I’ve  been up to when it’s late in the night!) but occasionally I need to use it to roll back to a previous commit. This is the command I always forget, and today it took me more than one minute to find the answer (or formulate the right question) on google.

The answer, unsurprisingly on stackoverflow: in your [git tracked] working directory enter this terminal command:

git reset --hard <tag/branch/commit id>

Where  you replace the gubbins inside the angle brackets with the SHA ID of your commit. Find this easily using GitX or my potential new favourite GIT client on the Mac: Gitti.
