I’ve posted a code snippet I used to sideload images from Flickr into WordPress, specifically for http://foodirl.com/ I originally stored all of my images on Flickr because I started the blog on Tumblr, knowing that I would move it later (which I did, to Crowd Fusion and then to WordPress).

	<?php
	/**
	* Retroactively sideload images referenced from Flickr.
	*/
	$flickr_sideload_media_id = null;
	function flickr_sideload_get_media_id( $media_id ) {
	global $flickr_sideload_media_id;
	$flickr_sideload_media_id = $media_id;
	}
	function flickr_sideload_init() {
	global $flickr_sideload_media_id;
	if ( isset( $_GET['do_flickr_sideload'] ) ) {
	add_action( 'add_attachment', 'flickr_sideload_get_media_id' );
	require_once( ABSPATH . 'wp-admin/includes/media.php' );
	require_once( ABSPATH . 'wp-admin/includes/file.php' );
	require_once( ABSPATH . 'wp-admin/includes/image.php' );
	$offset = 0;
	$limit = 10;
	while ( $posts = get_posts( 'posts_per_page=' . $limit . '&offset=' . $offset ) ) {
	$offset += $limit;
	foreach ( $posts as $post ) {
	if ( preg_match_all( '/(?<atag><a[^>]+href="(?<href>[^"]+)"[^>]*>)\s*(?<imgtag><img[^>]+src="(?<src>[^"]+)"[^>]+>)\s*(<\/a>)?/i', $post->post_content, $images, PREG_SET_ORDER ) ) {
	$post_content = $post->post_content;
	foreach ( $images as $image ) {
	if ( strpos( $image['src'], '.flickr.com/' ) !== false ) {
	$description_matches = array();
	$description = '';
	if ( ! empty( $image['atag'] ) ) {
	preg_match_all( '/title="(?<title>[^"]+)"/i', $image['atag'], $description_matches, PREG_SET_ORDER );
	}
	if ( ! empty( $description_matches ) ) {
	$description = $description_matches[0]['title'];
	}
	else {
	preg_match_all( '/alt="(?<alt>[^"]+)"/i', $image['imgtag'], $description_matches, PREG_SET_ORDER );
	if ( ! empty( $description_matches ) ) {
	$description = $description_matches[0]['alt'];
	}
	}
	$image_html = media_sideload_image( $image['src'], $post->ID, $description );
	preg_match_all( '/width="(?<width>[0-9]+)"/', $image['imgtag'], $width_matches, PREG_SET_ORDER );
	preg_match_all( '/height="(?<height>[0-9]+)"/', $image['imgtag'], $height_matches, PREG_SET_ORDER );
	if ( ! empty( $width_matches ) && ! empty( $height_matches ) ) {
	$size = array( $width_matches[0]['width'], $height_matches[0]['height'] );
	}
	else {
	$size = 'full';
	}
	if ( ! empty( $image['atag'] ) ) {
	$image_html = wp_get_attachment_link( $flickr_sideload_media_id, $size );
	}
	else if ( $size != 'full' ) {
	$image_html = str_replace( '<img ', '<img width="' . $size[0] . '" height="' . $size[1] . '" ', $image_html );
	}
	$post_content = str_replace( $image[0], $image_html, $post_content );
	}
	}
	if ( $post_content != $post->post_content ) {
	wp_update_post( array( 'ID' => $post->ID, 'post_content' => $post_content ) );
	}
	}
	}

	die;

	add_action( 'init', 'flickr_sideload_init' );

Stick it in mu-plugins and then load wp-admin/?do_flickr_sideload. It doesn’t have lots of error checking, but it worked flawlessly for FoodIRL’s 160+ posts.

A new plugin and theme for Keyring users

I’ve posted a new plugin that works with Keyring Social Importers to allow you to import activity from Reddit and a lifestreamy theme to show off all of the data that Keyring Social Importers can transfer to WordPress. Soon, you’ll be able to back up the entire Internet to a WordPress blog.

IM-porter plugin for WordPress

I released a new WordPress plugin this morning: IM-porter: Import your chat transcripts into WordPress. I wanted to save some decade-old AIM logs, so I wrote an importer to convert them into posts on a private blog. While I was doing that, I found more chat and IRC logs, so I extended the importer to handle those too.

IM-porter is extendable by other plugins too; to add support for a chat log format, just implement the abstract methods in the Chat_IMporter_Format class and add the class name to the array filtered by the chat_importer_formats filter.

Improving Post Previews

In WordPress ticket #25546, I propose that the features of my Inline Preview plugin be included in core. Come join the discussion!

Idea: Chaos Monkey WordPress plugin, which would randomly cause external HTTP requests to fail, disable other plugins, simulate DB unavailability — anything bad that might happen on a WordPress site that you might want to ensure doesn’t bring your site down entirely.

Inline Preview is now available via Extend: http://wordpress.org/plugins/inline-preview/

The latest version has a resizeable, collapsable, auto-refreshing preview frame, and it also improves your self-esteem. Check it out now!

Idea a WordPress plugin that lets you easily…

Idea: a WordPress plugin that lets you easily generate a Chat-formatted post from any comment thread on your site. Perfect for those times when you want to promote the interesting content that arises in the discussion following a post.

This weekend, I published a long-awaited plugin called Formategory. It lets you create post templates on a per-category basis, and it’s now on Extend.

I wrote a quick plugin this morning to export all of a site’s posts as simple HTML files. Here’s the background on the plugin, and here’s the sourcecode. Here’s an example of the plugin in action on my main blog.

I’ve updated my Feed Statistics WordPress plug-in to take advantage of all of the wonderful features added to WordPress in the last two years.

If you use WordPress as your primary feed distribution mechanism (instead of FeedBurner or a similar service), try out the plugin and get a good idea of how many people you’re reaching. Track total subscribers, post views, and link clickthroughs.
