Small Program Blog » WordPress http://blog.sunnycyk.hk Just another WordPress weblog Sat, 05 Nov 2011 06:32:15 +0000 http://wordpress.org/?v=2.8.1 en hourly 1 Wordpress and flash? http://blog.sunnycyk.hk/?p=351 http://blog.sunnycyk.hk/?p=351#comments Fri, 03 Jul 2009 05:33:48 +0000 Sunny http://blog.sunnycyk.hk/?p=351 ok. First I want to say: This may not work, just my idea how Wordpress and flash work together.

Since WordPress uses Database, you can actually retrieve your Blog from the database. What you need to do is write a script to retrieve those data and display it as XML or whatever data format you like. Then your flash movie should read XML (or other data format) and display it.

This purpose only good for read only.. since we are not modifying the database.. so I guess this should work well. If you want to do more advance stuff, then the best way is first to see how the database tables related to each other, then do an appropriate updates for each modification.

If you have a better idea, please let me know…

<?php
  /**
  * @package WordPress
  * @subpackage mySmallProgramTheme
  */
  ?>
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes(); ?>>

<head profile="http://gmpg.org/xfn/11">

  <link rel="shortcut icon" href="<?php get_bloginfo('url') ?>/wp-content/themes/mysmallprogramtheme/image/favicon.png" type="image/png" />

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
  <?php if (is_singular() ) wp_enqueue_script('comment-reply');
  ?>
  </head>
  <body>
  <div id="page">
  <div id="header">

  <div id="headerimage">
  <a href="<?php echo get_option('home'); ?>" ><h1><?php bloginfo('name'); ?></h1></a>
  <div class="description"><?php bloginfo('description'); ?></div>
  </div>

First, I have setup some header information with bloginfo() in the Header tag. You may just take a look how I did that because you mostly will put the same header as mine.

After the Header Tag, I defined a Wrapper layer “page”


<div id="page">

This is the wrapper for all contents in my blog. In this wrapper, usually you will define four different parts(or layers).

1. Header
2. Content
3. Footer
4. Sidebar

And for this example, this file is called header.php, so I will define our “Header” layer here. Next 5 lines, I have defined my “Header”:


 <div id="header">

  <div id="headerimage">
  <a href="<?php echo get_option('home'); ?>" ><h1><?php bloginfo('name'); ?></h1></a>
  <div class="description"><?php bloginfo('description'); ?></div>
  </div>

In the header layer, I have defined another wrapper called “headerimage”. This is because I want to wrap my Blog title and description in my header layer.

Later on, I will show you how I created index.php for my content layer. footer.php for my footer layer, and sidebar.php for my sidebar layer.

One more thing I forgot to mention, in header section, there is a php code:


 <?php if (is_singular() ) wp_enqueue_script('comment-reply');
  ?>

is_singular() will check if this page is a single post (only one post on the page, and actually there is a template file called single.php that you may also define it yourself or by WordPress default template. single.php is liked index.php which I will call my header, sidebar, and footer files here except it only displays one post per page). In my case, I only want to include javascript for replying a comment when someone land on single.php, or else the code should not be included.

So, it looks pretty simple right? However, don’t forget the code above has no decoration, so you will have to define your own CSS style for each layer and wrapper, or otherwise you will only see plain text on your header. 


body {
	font-size: 62.5%; /* Resets 1em to 10px */
	font-family: Arial, Helvetica, sans-serif;
	background: #ffffff;
	color: #333;
	text-align: center;

}

#page {
	border: none;
	background:url(image/layoutbg.png) repeat-y bottom center;

}

#header {
	background: url(image/headerpic.jpg) no-repeat top center;
}

#headerimage {
	width: 830px;
	height: 195px;
}

#header h1 {
	font-size:36px;
	text-align: center;
	color: #903;
}

#header a, #header a:visited {
	text-decoration: none;
	color: #903;
}

#header a:hover {
	text-decoration:underline;
}

#headerimage .description {
	font-size:14px;
	text-align: center;
	color: #666;
	font-family:Georgia, "Times New Roman", Times, serif;
	font-style:italic;
}

body {
	margin: 0px 0 20px 0;
	padding: 0;
}

#page {
	margin: 0px auto;
	padding: 0;
	width: 830px;
}

#header {
	margin: 0 0 0 0px;
	padding:0;
	height:195px;
	width: 830px;
}

#headerimage {
	margin: 0;
}

#header h1 {
	margin: 0;
	padding:70px 0px 0px 0;
}

#headerimage .description {
	margin: 0;
	padding:1px 15px 0 0;
}

Please forgive my mess. :) I defined them twice because I kinda modified from the default WordPress Theme which it separates the style of structure and coloring in two parts. You may just group them in one depends on what you like.

Then you need to handle space for each line. Also, you may want to highlight some keywords. There will be a lot of work, and some programming languages look really similar, but if you want to decorate them, you may have to do it one by one, and it could suck out most of your time.

Fortunately, WordPress has a plugin that helps you to do all the works for you. It is called Highlight, and you can download it and use it as WordPress plugin or just code it within your HTML file. You only need to assign some CSS style such as color for keywords. This is very nice because usually I like to program everything myself, but this really saves me a lot of time. (On the other hand, many things on the web are really useful).

For example,


<?php
if (is_home()) {
	echo bloginfo('name');
} elseif (is_404()) {
	echo '404 Not Found';
} else {
	echo wp_title('');
}
?>

and my CSS Style (which applies the highlight for the code above and below for showcase):


code {
	color: #000099;
	font: normal "Courier New", Courier, monospace;
	white-space: nowrap;
	padding: 0 2px;
}
pre code {
	display: block;
	clear: both;
	background: #FDF;
	color: #333;
	border: solid 1px #ccc;
	overflow: auto;
	line-height: 140%;
	white-space: pre;
	width: 470px;
	text-align:left;
}
code .comment {
	color: #888;
}
code .class, code .rules {
	color: #ff00ff;
	font-size: 100%;
}
code .value,  code .title, code .string {
	color: #0000FF;
}
code .tag {
	color: #000099;
}
code .keyword {
	color: #000099;
}
.html .attribute {
	color: #006600;
}

All I have done is just put all my code within <pre><code></code></pre> and it will decorate my code with my CSS style. Isn’t it really easy? yea, you can compare my old posts which I just use <p> and style it, and which still doesn’t look good.

One more thing, if you do not want to use it as plugin, you can just put these two lines of code on your web page (The WordPress plugin will automatically add these two lines to your WordPress blog) :


<script type="text/javascript" src="highlight.pack.js"></script>
    <script type="text/javascript">
      hljs.initHighlightingOnLoad();
    </script>

It is pretty easy, right?

I will say compare to this site, my blog for designing the WordPress Theme is a mess… haha..

It has many tricks too. Good for anyone wants to do some graphic and web design (same as me :) )

]]> http://blog.sunnycyk.hk/?feed=rss2&p=243 0 WordPress Theme – Sidebar http://blog.sunnycyk.hk/?p=224 http://blog.sunnycyk.hk/?p=224#comments Mon, 09 Mar 2009 17:05:38 +0000 Sunny http://blog.sunnycyk.hk/?p=224 In WordPress, there are widgets such as calender that may appear on your theme based on your appearance setting. Usually they will appear on sidebar when you add the widgets in the theme. If there is no widget adding to the sidebar, a function dynamic_sidebar() will return a FALSE value. This function is useful if you are designing a theme template because you may want to create something if there is no widget on the sidebar. For example, you may want to include your own widget to the sidebar if user has not included any widget in the theme appearance setting.

Further, if you want to add widget at the appearance setting, you will need to register the sidebar to WordPress in the file function.php. The function register_sidebar() will tell the plugin that your theme will need exactly one sidebar and your admin inteface should have Sidebar Widgets in the Presentation menu. register_sidebar() also allows you to decorate the widget by adding a parameter to it. For example,

<?php
if (function_exists(’register_sidebar’) )
register_sidebar(array(’before_widget’=>’ ‘,
‘after_widget’ => ‘ ‘,
‘before_title’ => ‘<div class=”title”>’,
‘after_title’=>’</div>’));
?>

before_widget and after_widget means that something that you want to decorate the widget.. you may think it can be a warper and you will warp your widgets. In this example, we put nothing, so there is no decoration for this widget warper. Then before_title and after_title, will decorate the wiget title with <div lass=”title”> and </div>. The output will look like this:

<div lass=”title”> Widgets Title </div>

What if you want to include more than one sidebar? Then instead of using register_sidebar(), you will use register_sidebars(n) where n is the number of sidebars. (starting with 1)

]]> http://blog.sunnycyk.hk/?feed=rss2&p=224 0 WordPress Theme – WordPress Loop http://blog.sunnycyk.hk/?p=157 http://blog.sunnycyk.hk/?p=157#comments Sun, 08 Mar 2009 09:22:24 +0000 Sunny http://blog.sunnycyk.hk/?p=157 WordPress Loop is the Loop that is used by WordPress to display each of your blog posts.  Using the Loop, WordPress processes each of the posts to be displayed on the current page and formats them within the Loop tags.

Basic WordPress Loop structure will look like this:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<!– something you want to repeat within the Loop tag –>
<?php endwhile; else: ?>
<p><?php _e(’Sorry, no posts matched your criteria.’); ?></p>
<?php endif; ?>

Let me explain what is going on. First, you need to know that there is a global object called $wp_query, and when WordPress generates your blog pages, it will build and execute a DB query that results in an array of posts, and which will store in the $wp_query object and also return back to the blog header where it is stuffed into the global $post array.

The have_posts() actually calls $wp_query->have_posts() which checks a loop counter to see if there are any pots left in the post array and return a boolean value TRUE if there is post or FALSE when we have exhausted the loop. And the_post() calls $wp_query->the post() which advance the loop counter and sets up the global $post variable as well as all of the global post data. On the other hand, It takes the current item in the collection of the posts and makes it available for use inside the iteration of the Loop.

Once you understand how the WordPress loop works, then you can use this loop for displaying your blog posts. So, here are some functions that you probably will put inside the WordPress loop:

the_title() – Display the current post’s title

the_time(format) – Display the date with format

the_author() – Display the author name

the_permalink() – a Permanent Link that point to the current post

the_content() – Display the content of the post

There are more technique you can use and display inside the loop. Here I just post some common functions that you will usually use, but there are more function you can do such as comment for the post. You can find more information here:

Using Conditional Tags for testing whether a certain condition is met, and then returns either TRUE or FALSE.

For example,
is_home() will return TRUE if the main blog page is being displayed.

Some of the conditional tags may contain parameters for conditions.  More information can be found here: http://codex.wordpress.org/Conditional_Tags

(Yea.. I just want to learn everything…)

This is my very first WordPress Theme.  Very simple, and kinda modified from the default theme which comes with WordPress.  I actually have hard time to understand the API and function references from WordPress when I was drafting it at the beginning, but it is kinda straight forward.  It is not completely done, and I may just zip it here when it is completed in the future.

I am not going to write much detail here, but going to put some references here for myself for future development.
