Sneaky OrderBy stuff.

July 30, 2012 No Comments

When ordering a query by meta_value, if you are using a numeric meta_value, do this:

$args = array( 
	'post_type' => 'msd_contest_entry', 
	'numberposts' => -1, 
	'meta_key' => 'Votes',
	'orderby' => 'meta_value_num'
	);
$items = get_posts($args);

Otherwise:

$args = array( 
	'post_type' => 'msd_contest_entry', 
	'numberposts' => -1, 
	'meta_key' => 'Votes',
	'orderby' => 'meta_value'
	);
$items = get_posts($args);

Adding JavaScript to the WP admin, an alternative idea

Can I use the same theming method I use on the front end to hook certain files to the backend and create a custom theme?

Javascript on just ONE Admin Page

June 25, 2012 No Comments

I ran into this issue recently when I had a setting page that allowed a file upload (image for logo) and the script for it started overriding the general image uploader across the entire admin. Grrf. A better way to hook the .js is found on Justin Tadlock’s blog. (I wasn’t able to do this exactly, but I used the idea.)

add_action( 'admin_menu', 'my_example_settings_page' );

function my_example_settings_page() {
	global $my_settings_page;

	$my_settings_page = add_options_page( 'DevPress Example', 'DevPress Example', 'manage_options', 'my-example-page-name', 'my_callback_function' );

	add_action( 'admin_enqueue_scripts', 'my_admin_enqueue_scripts' );
}

function my_admin_enqueue_scripts( $hook_suffix ) {
	global $my_settings_page;

	if ( $my_settings_page == $hook_suffix )
		wp_enqueue_script( 'my-example' );
}

Widgets Style

June 5, 2012 No Comments

Plugin idea: a plugin to add the ability to wrap any widget with a class. Would be great for the custom styled widgets like Cole likes.

Clean up WordPress revisions

May 31, 2012 No Comments

Salut,

Ce n’est pas suffisant, il y a deux autres tables affectees par l’autosave (wp_term_relationships et wp_postmeta), le code complet serait:

delete x,y,z
from wp_posts x
left join wp_term_relationships y on (x.id = y.object_id)
left join wp_postmeta z on (x.id = z.post_id)
where x.post_type = 'revision'
