Tag archive for "WordPress"

I received an emergency call from a client, his WordPress site didn't work. None of the logins either. Well, here's another script to the rescue if all you have left is an ftp login or some other way to upload files. It will create a new admin user with the … more

Update: See also http://kuttler.eu/code/wordpress-emergency-admin/ which is a little easier to use. Recently I had to update a site but didn't have an admin account or access to the SQL database. So I wrote this short script to reset a forgotten password. To use it, edit it and fill in the … more

Are you getting "You do not have sufficient permissions to access this page." errors everywhere in the WordPress admin? I had this happening on a site, apparently the problem is that somebody changed the database prefix. It's a little suprising that this would totally break the admin, but whatever... As … more

Run some code when a new blog is created. I'm not sure, but I guess this code has to be in a network-activated or mu-plugins plugin. Maybe having this code enabled in the blog you're using will suffice. more

This snippet shows how you can add metadata to your existing custom taxonomy. So you can use updatemetadata() and getmetadata() on your taxonomy. The filter on switchblog is only necessary if the code runs on a blog network (recommended to implement anyway). The name of the database table is very … more

Build a custom WordPress query and order the posts however you want them. Notice that this won't work properly if you page results, so it is only useful in very specific cases. Btw, wrap everything into your class and get rid o the global var when you use this ;-) more

If you build WordPress theme you'll eventually come to the point where you want to minify the stylesheets. But the WordPress theming system has a fundamental flaw: It expects theme headers like name, version information etc. to be in the style.css. This is bad because removing the headers from the … more

Show the user a useful search form when on a 404 page. Turn the query string into a search. more

There are many plugins that find related posts for WordPress, and I was happy to use one of them in the past. However, WordPress evolves. One of the biggest change was the addition of custom post types. They are very useful and I use them a lot for my own … more

The built-in recent posts widget in WordPress isn't too bad, but it doesn't support custom post types. That's why I wrote this new widget. You can choose any custom post types you want. This way you can always get a list of recent updates on your blog. The widget ignores … more

This plugin is for you if you like sharing your code. Turn your blog into a pastebin and keep your own code on your own site. You can tag your pastes like you tag your normal posts, and visitors can leave comments if you allow it. I wrote this because … more

This makes it possible to have the taxonomy below some post type slug, e.g. the post type is at /cars/ and taxonomies are at /cars/manufacturer/, /cars/year-of-construction/ etc. You want to register the taxonomy with the same $slug. more

Run the filter whenever you want your post type in the main loop. Add ishome(), iscategory() etc. Example is for the post type 'paste'. more

There's obviously a little context missing for this paste, but the basic idea should be clear ;-) more

With this you can upload images through your plugin/theme. They are saved as attachments. Please add nonce fields for security reasons. more

When you create WordPress plugins and themes it is often a good thing to test them on blogs with much data. Since 3.0 I use custom post types and custom taxonomies a lot and couldn't find a plugin that autogenerates them. Hence I wrote a new plugin. Features: Automatically create … more

With this snippet you can log in a WordPress user automatically. more

See my previous paste for the whole class (minus this) http://kuttler.eu/code/wordpress-plugintheme-options-page/ more

I use helper methods/functions in my themes and plugins to create the input fields, this was simplified for the example here. more

The function should probably check if the post already has the tag/category before adding it a second time. I should probably look into the wpispost_revision() part again as well. more

I like to enqueue my CSS styles because it has the benefit of adding a version string. A link like style.css?ver=0.7 is useful because it will force visitors to download an updated style.css when the version number is increased. Here's what I currently use in my functions.php: <?php if ( … more

This is a new plugin of mine that will turn many existing WordPress blogs and their themes into Ajax-powered blogs. The best way to see what this plugin does is to look at the live demo. The theme on that site wasn't tweaked at all to make the Ajax functionality … more

WordPress is stupid

2010-07-13

I have stopped using WordPress for personal projects and only use it professionally any more. In case you haven't been aware of this, WordPress core developers think that potentially breaking thousands of links on thousands of sites is an accepatable edge case. Here's a great summary of what has been … more

Several places recommend to block the WordPress admin area with a password. While this certainly is a good idea, implementing it properly is non-trivial. One of the problems is that the WordPress Ajax handler script is located in the admin directory. So password-protecting the admin area will break all Ajax … more

The new navigation menus system in WordPress 3.0 looks promising, but in my opinion it's not very usable yet. Anyway, here's one way to add navigation menus to your theme while maintaining backward compatibility: In your theme's functions.php add something like the following code: <?php function mytheme_addmenus() { register_nav_menus( array( … more

I recently converted several simple WordPress installs into a single WPMU install. As I use all of the blogs myself I wanted a quick way to switch between the various backends. This is probably only useful if you don't have too many blogs and use all of them yourself. The … more

I recently installed my first WordPress network on lighttpd and was looking for rewrite rules. This post is correct except for the rewrite rule for files. I supposed it's a change that was introduced in 3.0, or maybe earlier. Anyway, here are updated rewrite rules: In your lighttpd.conf: $HTTP["host"] =~ … more

Sometimes it's useful to put a WordPress loop inside another loop. To do this you'll have to create a new WP_Query object, as in this example: <?php $my_query = new WP_Query( "cat=3" ); if ( $my_query->have_posts() ) { while ( $my_query->have_posts() ) { $my_query->the_post(); the_content(); } } $GLOBALS['post'] = $GLOBALS['wp_query']->post; … more

Did you ever want to know what exactly your visitors are doing on your site? Watch them! A client of mine wanted a plugin to log what users type into forms. I kind of didn't see the point at first. But a few days later I was a little annoyed … more

I like WordPress, but I don't like the WordPress page system at all. That's why I recently converted all my plugin pages to posts. My main reasons for doing so were: Pages can't be tagged Pages don't have categories Pages and posts don't mix too well in custom loops Pages … more

Update: Apparently this code is also necessary when you want to list the comments on the blog page, and probably on archive pages as well. There could be a better solution, if you really care check out the P2 theme (and leave a comment). Sometimes you want to access WordPress … more

Not too long ago I wanted to add a new plugin to my blog. During various tests I noticed something quite shocking: at least one of the plugins insisted on loading it's CSS and jquery on every page of my blog. A little more testing showed me that many plugins … more

Zero Conf Mail

2009-10-11

It took me quite some time to check a few existing contact forms and I didn' t like any of them. No, I don't want you to load jquery on every page of my blog. I want it localized, pretty please. Oh, and I want this JavaScript onfocus/onblur effect I … more

Recently, I've been checking out some of the blogs that link back to me because they use one of my plugins. And it seems like a lot of them are using buggy, incorrect templates. It looks like many WordPress theme developers don't read the theme development checklist. Another fine document … more

This plugin adds a small form to every comment on your blog. The form is only added for admins and allows you to move comments to a different page and to fix comment threading. This plugin is not designed for mass-moving of comments, rather for moving single comments from time … more

Edit: I wrote a plugin to make this easier, see the move WordPress comments plugin page. Do you sometimes get comments that should be on a different post or page on your WordPress blog? I get such posts from time to time and always wondered how to move them to … more

This plugin shows fireworks on your WordPress blog. I think it's pretty stable by now, although the images still aren't that nice. If you're a designer and you like this plugin, feel free to submit nicer explosions or rockets. You should be able to see the fireworks on this page. … more

I was a little surprised when I realized that wp_title() doesn't return the page title for a static WordPress front page or the blog page. I don't like that, because I want at least the blog page to have a label. Something like... blog :-D or maybe news. So I … more

Comment paging is a great new feature in WordPress 2.7. However, how do you not display the pager when there are no previous or next comments? After digging through the code for quite a while and chatting with some people here's a solution: <?php if ( have_comments() ) { ?> … more

A Better Tag Cloud

2008-11-03

A Better Tag Cloud I was pretty annoyed with the default tag cloud widget. It does a lot of things wrong, like inconsistent HTML markup and hardcoded font sizes. So I wanted to write my own. Digging through the code I found out that the wordpress wp_tag_cloud() function is pretty powerful. In fact, it … more
