Adding extra user meta fields

On By westiIn Development, Tutorials, WordPress22 Comments

Last night there was a discussion as to what could be achieved today as part of a “WordHack” session at WordCamp UK and SimonD tweeted that he would like to be able to add extra user meta fields to the back end user profile page easily.

I tweeted back that it was already easy and so here is the proof of concept code which shows you:

  • How to add a user meta field to the page
  • How to process the new value when it is updated.

These can the been displayed on the front-end using the standard template tags get_the_author_meta() and the_author_meta()

/* Initialise outselves */
add_action('plugins_loaded', create_function('','global $pjw_user_meta_instance; $pjw_user_meta_instance = new pjw_user_meta();'));
?>

Enjoy!

Updated to correctly use the $user/$user_id passed to the actions rather than the global $user_id

Retiring WordPress version check

On By westiIn Development, Security, WordPress

I was reminiscing today on what the world was like when I released my WordPress version check plugin back in 2005.

What a different world it was, upgrading WordPress took time and people just didn’t bother even though new versions which contain security fixes had been released.

Now we are just about to get WordPress 2.8, people can upgrade with the click of a button and there hasn’t needed to be a security release for WordPress 2.7 how things change.

In celebration of this I have decided to take down the web-service which supported the plugin and have started the shutdown process by changing the message returned to point to this blog post.  So please un-install the plugin and rely on the notification that has been built in to WordPress for a few releases now.

Oh and don’t forget if your one of those people who has been ignoring these messages and are still running v1.5.2 (yes you know who you are) then please upgrade.

Searching for Children and Grandchildren

On By westiIn Development, Tutorials, WordPress2 Comments

I had a request recently for help on using my Query Child Of plugin to create a page template to show the grandchildren of a page as well as a number of people asking for better examples on how to use my plugin in general to just list the children of a page.

I am now happy to announce that I can provide these examples and have updated the plugin documentation on in the WordPress plugin directory to match as well.

Howto: Backup your iPhone on another machine

On By westiIn Technology, Tutorials

Jane asked –

“I’m nowhere near my iMac, and won’t be for weeks. I need to backup my iPhone onto my MacBook Pro or external hard drive today. How?!”

To which the answer is, suprisingly, use iTunes.

It turns out that once you have connected your iPhones to iTunes on another Mac you can just right click on the device and select backup like so:

backup-iphone

Hopefully this will help other people in a similar situation in the future.
