But it doesn’t have to be that way now, since newer versions of WP have a script loading API. So here’s a better way to do it, without modifying any core files:

First, we make a basic plugin file, where we tell WP to load some javascript, right after loading the quicktags script:

<?php
/*
Plugin Name: My Custom Quicktags
*/
 
add_action('admin_print_scripts', 'my_custom_quicktags');
function my_custom_quicktags() {
	wp_enqueue_script(
		'my_custom_quicktags',
		plugins_dir_url(__FILE__) . 'my-custom-quicktags.js',
		array('quicktags')
	);
}

Now, instead of modifying quicktags.js, we add our quicktag code in a separate file:

edButtons[edButtons.length] = 
new edButton('sup'
,'sup'
,'<sup>'
,'</sup>'
,''
);

Feel free to modify this to suit your needs.

The benefit of this method is that when you upgrade WordPress, your quicktag(s) will still be there.

I’ve made a .zip with these two files, which you can download and install as a regular plugin. It has been tested on WordPress 2.8.1 and 2.7.1.

I’d love to know what quicktags you make with this tutorial, so feel free to share in the comments.

Update: It seems someone has taken this a step further, with the Post Edit Buttons plugin. More power to him

To be honest, I don’t know what Jeff (the author of that post) is talking about. All the people that leave comments here have a grateful attitude, or are at least polite.

Actually, I want to thank them:

• the people who report bugs or post suggestions
• the people who make translations
• the people who spread the good word on their sites, on twitter etc.
• the people who simply make a small donation
• the people who offer me paid work

You guys rock! This site would probably not even be here, if it weren’t for you. Thanks!

OR query

?fruit=apple,orange,pair

will match all posts that have the fruit field set to apple OR orange OR pair.

AND query

?color=red+orange+yellow

will match posts that have 3 color fields: one with red, one with orange and one wih yellow.

These capabilities are disabled by default. Before you enable them from Posts -> CF Taxnomies, a word of caution:

If some of your field values have commas ‘,’ character in them, don’t enable the OR query.

Also, if some of the field values have spaces ‘ ‘ in them, don’t enable the AND query.

Currently, you can’t enable both the AND query and the “Show posts that don’t match all key=value pairs” option. This will probably be fixed in the future.

So I wrote this small plugin. To test it, start typing in the comment section below. Don’t press submit, because that’s not the point.

add_action('template_redirect', 'front_editor_load', 1);
function front_editor_load() {
	// Now the plugin will load only on single post pages.
	// Feel free to change the condition to meet your needs.
	if ( is_single() )
		return;
 
	remove_action('template_redirect', array('frontEditor', 'add_scripts'));
}

Just add this code in your theme’s functions.php file and you’re good to go.

Of course, it’s not a perfect 1:1 match.

WordPress also has filters, besides actions, and a few other functions for controlling both. jQuery, on the other hand, gives you the possibility to bind an event to one or more elements on the page.

The important thing is that if you understand one system, you will easily comprehend the other. I guess this is another reason why jQuery is the prefered library for the WordPress admin.

bbPress 1.0 has finally been released last week. But why do I use it? Why would anyone use it? Here are my 7 reasons.

It’s familiar

If you have any experience with WordPress 2.7 or older, you will feel right at home using the new bbPress admin. You imediatly get a sense that you already know how to use it, which is great.

It’s fast

Very fast, right out of the box, which is always important for users.

It scales

It has to scale, since it’s used for WordPress Support, which gets thousands of new messages daily.

It integrates with WordPress

Since it’s built on the same backend as WordPress, you won’t find any other forum software that integrates better.

It’s extensible

bbPress doesn’t include many of the features that other forum software have, but it has the same plugin architecture that made WordPress popular. That means you can add exactly the features that your users need.

It’s easy to brand

The theming system is similar to that of WordPress, so it’s pretty easy to tweak the design to make it your own. If not, you can always get a whole new theme from the interwebs.

It’s free

Last but not least, it’s free, as in beer – you don’t pay for it. It’s also open-source, being GPL licensed,  which is very important, at least for me.

So these are the 7 reasons why I’ll stick to bbPress.

You’ll notice the change when you use the Insert CFI button to add an image. Otherwise, you can still add the URL by hand.

A Default URL option was also added in this version, so that all posts can have an image, making your site more uniform.

The template tags have also changed, for the better, I hope.

These are the declaration for the template tags now:

custom_field_image($post_id = '', $defaults = '');
 
get_custom_field_image($post_id = '', $defaults = '', $format = 'html');

Say you want to override the default alignment. You can do that by adding this code:

<?php custom_field_image('', 'align=right'); ?>

If you also wanted to override the alt text, you would do this:

<?php custom_field_image('', 'align=right&alt=icon'); ?>

And so on, with any parameter: url, id, size, align, alt, link.

Props to Separatista for taking the time to make a Czech translation.

And props to Mike for pitching in with suggestions.

Today I found out.

Say you have this code:

foo = 1;
function test() {
	foo = bar;
}
test();
alert(foo);
 
// Result: 'bar'

It turns out that foo will be modified from the test() function.

If you are coming from PHP scripting, like I am, you will find this very unusual.

Now, if you used var:

foo = 1;
function test() {
	var foo = 'bar';
}
test();
alert(foo);
 
// Result: 1

foo would remain unchanged.

It even works with functions declared as variables:

foo = 'something';
function test() {
	var foo = function() {
		alert('bar');
	};
}
test();
alert(foo);
 
// Result: function()

So, var affects the variable scope:

Inside a function, all undeclared variables are global. Only those declared with var are local. This becomes very important when you have a lot of scripts running on the same page.

You might say that var is the opposite of the global keyword from PHP.

While tackeling the problem on this site, all I could find was baseline rhytm calculators. Sure, that helps a little, but it wasn’t quite what I needed. So I wrote this bookmarklet, creatively named “Baseline Checker”.

What it does

It draws equally spaced horizontal lines on top of a webpage. The position and the distance between the lines is calculated in reference to a particular element on that page.

With it, you can see for yourself if the baseline is consistent or not.

How to use it

1. “Install” the bookmarklet by dragging ( Baseline Checker ) to your bookmarks menu.
2. Go to a webpage and then click the bookmarklet.
3. Click an element on the page.
