How to Add a Digg Button to a WordPress Post

Andrea Ercolino — Wed, 01 Oct 2008 21:36:07 +0000

See the Digg button? {[ 1.diggthis() ]} is the enzyme I wrote for displaying it. I think it’s useful to have a means for adding a Digg button to a post only when and where you need it.

Of course you can put the same enzyme in a template (using the metabolize function), and you’ll see a Digg button into each and every post, but I prefer the on-demand way.

Now I’ll show you my setup.

1. Add a ‘diggthis-code’ custom field

As usual, I add the enzymes I’m going to use over and over, into the post number 1, the one that WordPress gives you by default.

This custom field is for the code that Digg tells you to use. I prefer to isolate external codes into their own custom fields, so this one is just for that:

2. Add a ‘diggthis’ custom field

This custom field is for the enzyme:

$post = $this->post;
$url = post_permalink( $post->ID );
if( false !== strpos( $url, '://localhost/' ) ) {
  return '[no digg for localhost]';
}
$title = $post->post_title;
$code = $this->elaborate( "1.diggthis-code" );
$code = $code[0];
$code = str_replace( 'WEBSITE_URL', $url, $code );
$code = str_replace( 'TITLE', $title, $code );
$style = $this->substrate;
if( '' != $style ) {
  $style = ' style="' . $style . '"';
}
$code = '
' . $code . '';
//return htmlspecialchars( $code );
return $code;

Line 1: get the current post object
Lines 2-6: get values for the variables of the widget
the localhost shortcircuit is a Digg requirement; if you don’t return, you’ll see an error
Lines 7-10: get the widget and set its variables
Lines 11-14: get custom style from the enzyme’s substrate, if any
Line 15: decorate the widget
reverse P-wrap is needed because WordPress automatically applies a P-wrap and a DIV into a P is not allowed
Line 16: useful for debugging
Line 17: return the widget

3. Use it

That’s it. For displaying a new Digg button now, right here

I wrote {[ 1.diggthis( =float: right; margin-left: 1em;= ) ]}. This time I overwrite the CSS for the class diggthis that I put into my theme:

.diggthis {
	float: left;
	margin-right: 1em;
}

WordPress Action and Filter Hooks

Andrea Ercolino — Sun, 13 Jul 2008 21:11:36 +0000

These are all the action and filter calls in WP 2.5.0. For each call I show its arguments and where it occurs into the code.

Actions

function do_action( $tag, $arg = '' ) {...}                                    -- wordpress-2.5.0/wp-includes/plugin.php (271)

function do_action_ref_array( $tag, $args ) {...}                              -- wordpress-2.5.0/wp-includes/plugin.php (354)

Fixed Name Actions

A call takes the form do_action( , , , … )

How to load JavaScript in WordPress plugins

Andrea Ercolino — Sun, 30 Mar 2008 20:43:39 +0000

If you want to load some JavaScript files from your WordPress plugin you have at least two options.

Head hooks

When building up a page, just before the closing tag of the head element, a theme should call actions hooked on wp-head. Those actions only need to output what they want to include into the head element, like script files.

What if a theme does not do that? Well, I’d include it into the so called “known issues”. For example, my last WordPress plugin, won’t work in this case. I think it’s better not to find a workaround, so that theme authors understand that they must follow WordPress standards.

On the other hand, there is also an admin-head hook, which is the wp-head hook counterpart when building up admin pages. For example, you could use the following function.



function load_into_head() { 
	$ADMIN_VIEW = "alert( 'Hello Admin!' );";
	$USERS_VIEW = "alert( 'Hello World!' );";
	?>

	
}

add_action( is_admin() ? 'admin_head' : 'wp_head', 'load_into_head' );

?>





Script API
WordPress provides also a good Script API that will let you do anything you want with script files, following WordPress standards. These are the main functions:

wp_deregister_script
wp_register_script
wp_enqueue_script
wp_print_scripts (action hook)
print_scripts_array (filter hook)

The general idea is that you write a function for loading your scripts using wp_deregister_script, wp_register_script, and wp_enqueue_script, and hook it on wp_print_scripts. If you also need to fine tune the order in which files are loaded or if they have to be loaded at all, then you can write another function and hook it on print_scripts_array.
deregister, register, and enqueue
wp_register_script let’s you create an alias and define dependencies for each script file. If a script file with the same alias was already registered, then your registration is ignored. This is a policy for conflict resolution (the first registration wins) that may help you, if you know it.
wp_deregister_script let’s you remove an alias. If the alias you give doesn’t exist, nothing happens. Tipically you use this function for forcing a new registration of an already registered alias: first you deregister and then register again.
wp_enqueue_script prepares the loading of a script. If the script was registered with some dependencies, this function automatically prepares their loading too, recursively, making sure each script will be loaded only once and before any script depending on it.
For example, jQuery 1.2.3 is registered by WordPress 2.5, but let’s say that you want to always download the latest version. You could use the following function.


function load_with_api() {
	wp_deregister_script( 'jquery' );
	wp_register_script( 'jquery', 'http://code.jquery.com/jquery-latest.pack.js', false, '' );

	//keep jQuery and Prototype compatible
	$url = get_bloginfo('wpurl').'/wp-content/plugins/my-plugin';
	wp_register_script( 'jquery_no_conflict', $url . '/jquery_no_conflict.js', array( 'jquery' ), '' );	
	wp_enqueue_script( 'jquery_no_conflict' );
}

add_action( 'wp_print_scripts', 'myOwnTheme_init' );

?>




Keeping jQuery and Prototype compatible is a needed functionality, because WordPress uses both and they both use $ as a global symbol. In fact, the jQuery file packed with WordPress includes the compatibility setting.
Fine tuning
If you want your scripts to be loaded in a particular order, with one script before or after another, maybe with respect to one that was registered by WordPress itself, or by other plugins, then you can write a function for the print_scripts_array filter.
For example, to load the jquery_no_conflict file just after the jquery file, you can use the following function.


function jquery_no_conflict_follows_jquery( $js_array ) {
	if ( false === $jquery = array_search( 'jquery', $js_array ) )
		return $js_array;

	if ( false === $jquery_no_conflict = array_search( 'jquery_no_conflict', $js_array ) )
		return $js_array;

	if ( $jquery_no_conflict == $jquery + 1 )
		return $js_array;

	array_splice( $js_array, $jquery + 1, 0, 'jquery_no_conflict' );

	unset($js_array[$jquery_no_conflict + ($jquery_no_conflict < $jquery ? 0 : 1)]);

	return $js_array;
}

add_filter( 'print_scripts_array', 'jquery_no_conflict_follows_jquery' );

?>




My Own Theme
If you want to see all this in action, you can install the My Own Theme plugin.



WP Chili Released
Andrea Ercolino — Fri, 14 Mar 2008 22:04:20 +0000
A couple of days ago I released WP Chili, a simple WordPress plugin that installs Chili into WordPress and let’s you add client-side code highlighting to your posts, with extreme simplicity.
After activating WP Chili, it’s just a matter of wrapping your snippets into code or pre-code elements, with the programming language of the snippet as a class, like in the following example:

echo "Hello $name";

When the post reaches your readers, the snippet is unescaped by their browser and highlighted by Chili 1.9 (downloaded from your server). Your readers will see the example rendered as:
echo "Hello $name";




WordPress Rendering Troubles
Andrea Ercolino — Sat, 24 Nov 2007 22:41:59 +0000
WordPress has many helpers that allow authors to write down some text and have it nicely formatted for their readers, without having to care about HTML issues. It’s a great job, but sometimes it doesn’t do the right thing.
This bug affects content and custom fields, which means that it’s more of a conceptual bug than a coding bug. I wrote an article with a workaround for the content. Now, let’s see a simple fix for custom fields.
I’ll describe both problems I detected and give a solution based on changing some WordPress code. I know it’s not a perfect solution, but it works and it’s also relatively easy. In the snippets you’ll see the code as it’s supposed to get changed to. (with 3 lines of context before and after changed lines, each preceded by a //noteslog.com comment)
WordPress Version: 2.3.1
Problem: HTML Entities Conversion
Custom fields that have HTML entities in their key or value are treated by WordPress weirdly. Frustration will appear soon after realizing that WordPress won’t return what you put in before.
If I write ¶ inside the visual editor of a post, WordPress should assume that I want to visualize ¶. In fact it will pretend to do the right thing the first time I save the post. All subsequent times it will show a ¶ where I put a ¶.
If I write ¶ inside the code editor of a post, WordPress should assume that I want to visualize ¶, and it does the right thing (sort of, because I now have a ¶ inside the code too).
If I write ¶ inside a custom field’s key or value, WordPress should assume that I want to visualize ¶ for my readers, and ¶ for myself when I’m authoring the custom field. In fact WordPress does the wrong thing here again, because it’ll immediately convert ¶ to ¶.
Solution
This fix requires changing four lines in two files. We’ll use the PHP function htmlspecialchars in place of the WordPress function attribute_escape. After the fix, filters for “attribute_escape” won’t get applied to custom fields keys and values. (this shouldn’t be a problem)
Open: wp-admin/admin-ajax.php

Search: function wp_ajax_meta_row

add_action( 'shutdown', 'get_out_now', -1 );

function wp_ajax_meta_row( $pid, $mid, $key, $value ) {
//noteslog.com
	$value = htmlspecialchars( $value ); //attribute_escape($value);
	$key_js = addslashes(wp_specialchars($key, 'double'));
//noteslog.com
	$key = htmlspecialchars( $key ); //attribute_escape($key);
	$r .= "";
	$r .= "";
	$r .= "$value";

Open: wp-admin/includes/template.php

Search: function list_meta

}

		$key_js = js_escape( $entry['meta_key'] );
//noteslog.com
		$entry['meta_key']   = htmlspecialchars($entry['meta_key']);//attribute_escape($entry['meta_key']);
//noteslog.com
		$entry['meta_value'] = htmlspecialchars($entry['meta_value']);//attribute_escape($entry['meta_value']);
		$entry['meta_id'] = (int) $entry['meta_id'];
		$r .= "\n\t";
		$r .= "\n\t\t";

Problem: White Space Trimming
Custom fields that begin or end with white space in their key or value are trimmed. I can undestand that a key is more easily dealt with if it is trimmed before saving it into the database. But values should definitely retain all their white space AS IS.
Solution
This fix requires changing four lines in three files. We’ll add a $trim parameter to the wordpress function maybe_serialize, by default set to true. Wherever we do not want a $data value trimmed, we’ll call maybe_serialize with a false second argument.
Open: wp-includes/functions.php

Search: function maybe_serialize

return true;
}

//noteslog.com
function maybe_serialize($data, $trim=true) { //($data)
//noteslog.com
	if ( $trim && is_string($data) ) //( is_string($data) )
		$data = trim($data);
	elseif ( is_array($data) || is_object($data) )
		return serialize($data);

Open: wp-admin/includes/post.php

Search: function add_meta

$metakeyselect = $wpdb->escape( stripslashes( trim( $_POST['metakeyselect'] ) ) );
	$metakeyinput = $wpdb->escape( stripslashes( trim( $_POST['metakeyinput'] ) ) );
//noteslog.com
	$metavalue = maybe_serialize( stripslashes( ( $_POST['metavalue'] ) ), false ); //( stripslashes( trim( $_POST['metavalue'] ) ) );
	$metavalue = $wpdb->escape( $metavalue );

	if ( ('0' === $metavalue || !empty ( $metavalue ) ) && ((('#NONE#' != $metakeyselect) && !empty ( $metakeyselect) ) || !empty ( $metakeyinput) ) ) {
		// We have a key/value pair. If both the select and the

Open: wp-admin/includes/post.php

Search: function update_meta

if ( in_array($mkey, $protected) )
		return false;

//noteslog.com
	$mvalue = maybe_serialize( stripslashes( $mvalue ), false ); //( stripslashes( $mvalue ) );
	$mvalue = $wpdb->escape( $mvalue );
	$mid = (int) $mid;
	return $wpdb->query( "UPDATE $wpdb->postmeta SET meta_key = '$mkey', meta_value = '$mvalue' WHERE meta_id = '$mid'" );




Enzymes 2.0 Released Today
Andrea Ercolino — Sat, 10 Nov 2007 22:55:43 +0000
Enzymes is a WordPress Plugin for retrieving properties and custom fields of posts, pages, and authors, right into the visual editor of posts and pages, and everywhere else.
I’m releasing now Enzymes 2.0 which is quite a step forward. The features are

a new syntax for retrieving properties of posts, pages, and authors; as well as the old syntax for custom fields
a new syntax for identifying posts and pages by means of their slugs; as well as the old syntax with their numbers
a new elaborate method allowing for an easier processing of indirect arguments
a new merging method helping at crafting how the pathway is built by evaluation enzymes
slash and backslash templating uniformly supported by transclusion and evaluation enzymes
a cleaner code
a new manual
new examples

A WordPress Plugin
This version is available for download from wordpress.org
The previous version
I released Enzymes 1.2 one year ago from mondotondo.com, and re-released it as version 1.3 one month ago from wordpress.org. Both were almost the same thing. Here are the only differences:

updated the description header, accounting for the new address (notelog.com)
removed the signals to my server for activation / deactivation of the plugin
packaged as a wordpress plugin, available for download from wordpress.org




How to add semantics to WordPress posts
Andrea Ercolino — Fri, 02 Mar 2007 09:49:35 +0000
Browsing the WordPress’ ideas repository I’ve found one that could make WordPress fill the gap between a blog tool and a knowledge base: Structured Blogging.
The fact that it got 60 votes but only 50% stars means two things:

voting people are lazy thinkers
it’s a difficult task at many levels

Nonetheless it’s a good idea because this is and will be for many years to come the blogging era, where millions of authors post content to the Internet. There is no good reason for that content to be unstructured except lazyness and complexity.
Nothing can be done about lazyness but complexity can be substantially reduced. The solution needs:

a mechanism for adding XML tags from some dictionary
a template system for showing XML content appropiately

On the path to something readily usable (I hope Matt will provide it in WordPress 3.0), a mechanism could be a jQuery plugin for the visual editor, and a template system could be based on Enzymes.
Autocompletion
I think that tinyMCE can be extended by plugins, but I don’t know how to. jQuery itself has an autocompletion plugin that could be used this way. When an author presses a < key, the autocompletion gets triggered and the popup … pops up :-)
If you have ever used IME (for Japanese for example), you should know what I mean. Options are organized in a hierarchy and you get the most relevant at the top, depending on the few characters already typed. XML dictionaries could be ajaxed and locally cached; they could be plugins that you install into your blog, or be web services too; they could be international standards compliant or be completely custom.
The most-relevant-first feature of the autocompletion popup would be a big help for authors. If I already opened a Tag, then the most relevant options after pressing < could be:

the closing tag for that Tag
any tag that could be inside that Tag (properly sorted if needed)
any root of the cached dictionaries (if possible in Tag)
an option for accessing additional dictionaries (if possible in Tag)

Templates
A PHP template for properly rendering XML content is very easy to write, and Enzymes could be used in the clockwork. In fact an Enzymes feature is the possibility of easily transcluding all the content of a post or a page by means of the special char *
The XML to HTML template can be transformed in an Enzymes template with a couple of PHP instructions, thus allowing you to almost copy and paste already available templates. Then you could apply a solution like this:

write a private post or page with the XML content, using the autocompletion feature described above (say this post is #123)
write a public post or page with the Enzymes statement {[123.* /template.php]} in its content

The post in 1. needs to be private because you don’t want it to appear on the blog as is, and 2. makes the transformation happen. As an added benefit, you can display that semantic content inside of a greater context, and you can transclude it wherever you want in your WordPress blog (as many times as you like).



Found the Culprit of the Pacman’s Effect
Andrea Ercolino — Thu, 22 Feb 2007 12:22:50 +0000
Some time ago I wrote Entity enzyme, or The pacman effect strikes back. It was an article about the pacman effect of the ampersand in WordPress and how to try to solve it with a simple enzyme. Recently I’ve discovered that it’s an escaping / unescaping issue still unresolved in WordPress 2.1, and it’s somewhat nastier than I initially thought.
If you want to write HTML entity codes in a post, and you need to represent that of an ampersand for example (it’s &), then there is no way to get it right. In fact, WordPress will always resolve an entity code.
Thus, if you write &, you’ll get & after the first save roundtrip, and if you try to escape the & into & with &, obtaining &amp; (this looks weird but it’s the way to do it in plain HTML), then the first time you save the post you get & back, and the second time you save the post you get & back.
In general if you write & followed by any number of amp; (like &amp;amp;amp;amp;amp;amp;) then WordPress will make the & eat up an amp; at each saving roundtrip, hence the pacman effect.
But the title of my previous post about this issue was “the pacman effect strikes back.” In fact it’s not only a problem of the post content but also of the custom fields, thus corrupting the last resort we WordPress bloggers have for content AS IS. And this is where I get really upset.
Last tuesday I found the culprit and asked the wp-hackers list wether they considered it a bug or not. I’m still waiting for an answer, so I hope this post will help me to broaden the question and understand if I need to submit it to WordPress Trac or go in for a hack myself.




How to Highlight Mixed Language Source Code
Andrea Ercolino — Fri, 16 Feb 2007 15:35:29 +0000
Web pages contain many snippets from different languages, like HTML, PHP, CSS, and JavaScript. Chili 1.x cannot highlight mixed language source code automatically, but the forthcoming released Chili 2.0 will be is able to do that.
Meanwhile, if you are using a Chili + Enzymes setup, then it’s possible to write an Enzymes template capable of making Chili 1.x highlight a web page perfectly (expanding on my previous php template).
Here is the new updated (2007/02/19) chili-web.php Enzymes template. At the moment it supports XHTML, and embedded CSS, JavaScript, and PHP snippets.
'.htmlentities( $code ).'';
	}

	function snippet_php( $open, $code, $close ) {
		return snippet_wrap( 'html', $open ).snippet_wrap( 'php', $code ).snippet_wrap( 'html', $close );
	}

	function php_inside_html( $matches ) {
		list( $all, $before, $open, $code, $close ) = $matches;

		if( '' == $open ) 
			return snippet_wrap( 'html', $all );
		else 
			return snippet_wrap( 'html', $before ).snippet_php( $open, $code, $close );
	}

	function php_inside_css( $matches ) {
		list( $all, $before, $open, $code, $close ) = $matches;

		if( '' == $open ) 
			return snippet_wrap( 'css', $all );
		else 
			return snippet_wrap( 'css', $before ).snippet_php( $open, $code, $close );
	}

	function php_inside_javascript( $matches ) {
		list( $all, $before, $open, $code, $close ) = $matches;

		if( '' == $open ) 
			return snippet_wrap( 'javascript', $all );
		else 
			return snippet_wrap( 'javascript', $before ).snippet_php( $open, $code, $close );
	}

	function php_inside( $class, $code ) {
		return preg_replace_callback( '/(?:(.*?)(\<\?php\s)(.*?)(\?\>))|(?:.+)/si', "php_inside_$class", $code );
	}

	function snippet_web( $class, $open, $code, $close ) {
		return snippet_wrap( 'html', $open ).php_inside( $class, $code ).snippet_wrap( 'html', $close );
	}

	function format_code( $matches ) {
		list( $all, $before, $open, $tag, $code, $close ) = $matches;

		if( '' == $open ) {
			return php_inside( 'html', $all );
		}
		else {
			switch( $tag ) {
				case 'script': $class = 'javascript'; break;
				case 'style' : $class = 'css';        break;
				default      : $class = 'html';
			}
			return php_inside( 'html', $before ).snippet_web( $class, $open, $code, $close );
		}
	}

	function format_clean( $out ) {
		do {
			$len = strlen( $out );
			$out = preg_replace( '/(\[^<]*)\<\/code\>\/is', '$1', $out );
		} while( $len != strlen( $out ) );
		return $out;
	}
}

?>
)(.*?)(\<\/\3\>))|(?:.+)/is', 'format_code', $this->result );
	echo format_clean( $out );
?>

The WordPress file /wp-content /themes /default /comments-popup.php is a page that uses all the supported languages, so it’s a good test for the previous template:




     <?php echo get_option('blogname'); ?> - Comments on <?php the_title(); ?>

WordPress Custom Fields Restyling
Andrea Ercolino — Mon, 12 Feb 2007 23:20:44 +0000
I use Custom Fields a lot, always by means of Enzymes, for managing the code snippets I’m going to comment about.
The Custom Fields section inside the post editing page shows added custom fields in a table whose columns change their width to fit the content, but the rows don’t change their height. I do not like that design: a definition list is much better than a table there. The key is the definition term and the value is the definition data.
Here are some pictures about the results of my experiment. The first row is my restyling, and the second row is how the same data appear in the usual design. There are three custom fields already added to this post: snippet1, snippet2, and snippet3; in the right picture, a new google custom field is going to be added
 ,  , 

Features of my restyling

added fields and the new field are evenly represented by the classical definition list style, where definition data is indented below the definition term; this provides a powerful clue for identifying the key / value roles, thus making all the labels superfluous
space usage is smarter; the key spans all the available width; the value almost all of it, and its height is greater than usual too, thus allowing for a convenient inspection, for viewing and editing purposes; the vertical scrollbar is much more useful than the horizontal one
by clicking its key, a custom field gets expanded, thus showing its value and its two editing buttons, while the rest of the custom fields gets collapsed; showing only one custom field at a time helps keeping user’s attention focused
the selection box for chosing an already known-to-the-system key is replaced by a list of buttons, located above the key field; by clicking any of them, the key gets copied into the key field, so that the user can leave it alone or change it, if needed; the overall design is more coherent
