How to make wordpress plugin: General

Posted by in PHP code, Wordpress plugin on July 21st, 2009

This article will present you with the basics of wordpress plugin. I have create a plugin to help you understand how to create a plugin. This simple plugin shows a digg button to all your post. You can download the full code here. Below is several code I use:

class diggme
{
function diggme() {

add_action(‘init’, array($this, ‘init’));
add_action(‘admin_menu’, array(&$this, ‘setmenu’));
add_filter(‘the_content’, array(&$this, ‘the_content_filter’));
}

function init()
{
?>
<link href=”<?php echo get_option(‘siteurl’); ?>/wp-content/plugins/diggme/css.css” rel=”stylesheet” type=”text/css” />
<?php
}

function managepage(){
echo “<div id=’setting’>This is setting page. Just ignore this</div>”;
}

function setmenu () {
add_options_page(
‘DiggMe’,
‘DiggMe’,
‘manage_options’,
__FILE__,
array(&$this,’managepage’ ) );
}

function the_content_filter($content)
{
return $this->displaydigg() . $content;
}

function displaydigg()
{
global $post;

return “<div id=\”diggbutton\”><a href=\”http://digg.com/submit?phase=2&amp;url=”.get_permalink($post->ID).”\”><img src=\”".get_settings(‘siteurl’).”/wp-content/plugins/diggme/digg.png\”></a></div>”;
}

}

$diggme = new diggme();

  • The code will first create a class called diggme. Every time the plugin loads it will create an object of this class using $diggme = new diggme();

The constructor

  • add_action(‘init’, array($this, ‘init’)); -> This will tell your blog to execute function init whenever it loads.
  • add_action(‘admin_menu’, array(&$this, ‘setmenu’)); -> This will tell your blog to create menu at your admin page. You can place any settings here.
  • add_filter(‘the_content’, array(&$this, ‘the_content_filter’)); -> This will be executed every time when your post loads. In this example we will load function the_content_filter every time the page loads, read the post content and add a digg button to the post.

Other function is easy to understand if you have basic PHP skill. If you have any question just comment below.

jQuery reload page

Posted by in Jquery on July 18th, 2009

When you load a page using require PHP function, there is time when you want to reload the page in require PHP function again. You can do this by using the require in a div. Then load the page again using jQuery load function.

Here’s the code in the main page:

<html>
<head>
<script type=”text/javascript” src=”jquery.js”></script>
<script type=”text/javascript”>
function  reload()
{
$(“#page”).load(“page.php?value=test”);
}
</script>
</head>
<body>
<div id=”page”>
<?php
require(“page.php”);
?></div>
<br>
<input type=button value=”Click to reload page.php” onclick=”reload();”>
</body>
</html>

And the function in page.php:

<?php
echo “Test value = ” . $_GET['value'];
?>
