To cut a long story short, this issue was driving me insane, and I was frantically trying to pin down the cause of the problem. I eventually tracked down the culprit. It was the Events Calender plugin.

If you’ve installed the Events Calender plugin, and you’re experiencing the CSS bug, continue reading, I have a solution for you. If you’re experiencing this problem but DON’T have the plugin installed, I probably don’t have a solution for you. But the root of the problem maybe of a similar nature, as in a plugin you have installed is causing the issue.

The solution for those that have the Events Calender plugin installed

Step 1: Find the file eventcalandar3.php, located in /wp-content/plugins/event-calandar/.

Step 2: Find the following function, ec3_get_the_excerpt.

Step 3:
Replace:

1

$text=strip_tags($text);

With:

1

$text=strip_tags($text, '<style>');

Step 4:
Upload the new eventcalandar3.php file. I would suggest keeping a backup of the original file.

That should have resolved the problem. Phhheeeeew!

Please let me know if this helped anyone. I’m curious to know if this issue has plagued anyone else!

<link rel="EditURI" type="application/rsd+xml" title="RSD" href="" /> 
<link rel="wlwmanifest" type="application/wlwmanifest+xml" href="wlwmanifest.xml" /> 
<link rel='index' title='BrightCherry' href='http://www.brightcherry.co.uk' /> 
<link rel='start' title='What is BrightCherry?' href='' /> 
<link rel='prev' title='' href='' /> 
<meta name="generator" content="WordPress 2.9.2" />

Most of it is unnecessary, and only delays the load time of the page. To prevent those elements from loading, you can add the following lines to the “functions.php” file which is located in your theme directory.

remove_action( 'wp_head', 'feed_links_extra', 3 ); // Removes the links to the extra feeds such as category feeds
remove_action( 'wp_head', 'feed_links', 2 ); // Removes links to the general feeds: Post and Comment Feed
remove_action( 'wp_head', 'rsd_link'); // Removes the link to the Really Simple Discovery service endpoint, EditURI link
remove_action( 'wp_head', 'wlwmanifest_link'); // Removes the link to the Windows Live Writer manifest file.
remove_action( 'wp_head', 'index_rel_link'); // Removes the index link
remove_action( 'wp_head', 'parent_post_rel_link_wp_head', 10, 0); // Removes the prev link
remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0); // Removes the relational links for the posts adjacent to the current post.
remove_action( 'wp_head', 'wp_generator'); // Removes the WordPress version i.e. - WordPress 2.8.4
remove_action( 'wp_head', 'wp_shortlink_wp_head', 10, 0 ); // Removes the shortlink link
remove_action( 'wp_head', 'start_post_rel_link');

Save the file, upload it. Next time you look at the source code, those unneeded elements won’t load.

Note: I’ve tested this for WordPress version 3.0.1 and it works. All the actions above may not work for previous versions.

So I wrote some code which allowed me to do exactly that. In the single.php page, replace the following code:

1

<?php the_content(); ?>

<?php
$show_after_p = 1;
$content = apply_filters('the_content', $post->post_content);
if(substr_count($content, '<p>') > $show_after_p)
{
	$contents = explode("</p>", $content);
	$p_count = 0;
	foreach($contents as $content)
	{
		echo $content;
 
		if($p_count == $show_after_p)
		{
		?>
                INSERT ADSENSE CODE
		<?
		}
		echo "</p>";
		$p_count++;
	}
}
?>

That code will automatically display your Adsense unit after the first paragraph. You can modify $show_after_p = 1, which will control which paragraph you want the unit to display after.

If the $show_after_p value exceeds the amount of paragraphs there are in a post, the ad unit won’t display.

If anyone knows a better solution, please let me know. And if anyone decides to use the code, let me know if it works for you.

From what i’m aware, currently, WordPress doesn’t allow enough flexibility when it comes to manipulating categories, especially when it comes to identifying the difference between a “Parent” and “Child” category. Let me explain…

The “Depth” Parameter

WordPress only recently added a “depth” parameter, which allows you to pull out ONLY parent or child categories. However, it still isn’t flexible enough because you can only use it with limited functions.

<ul>
<?php
wp_list_categories('depth=1'); ?>
</ul>

The above code will list all parent categories in a list format. The downside of this approach? It’s not flexible enough because it lists the parent categories as links. But if that’s all you’re after, that’s cool. But If you want more flexibility with categories, that won’t help.

Putting Categories Into a Foreach Loop And manipulating

The solution to the problem above is as follows:

1

$categories = get_categories();
foreach ($categories as $cat)
{
  if($cat->parent < 1)
  {
    echo $cat->category_nicename
    echo $cat->cat_name ;
   }
}

The above code will put the categories into an array, meaning you can now pass the values through a foreach loop (as shown in the code), consequently, you can completely control how you want the categories to display. In the example, I’m only printing the category name and category nice name (category url). But you can print out a lot more, which I explain a bit further down

The $cat->parent variable prints the parent of each category. If the category doesn’t have a parent, it has a value of 0. So by adding the if($cat->parent < 1) condition, we prevent all child categories from displaying.

To view all the values in the array or further possible manipulation, print the following array:

1

print_r($categories);

I hope that’s been useful

Example

All you really need is one simple function. So for example, in your header you may have an image which you want to appear on the homepage:

The Code

1

<?
if (is_home() && ) {
?>
<img src="http://www.brightcherry.co.uk/images/logo.png" title="brightCherry Logo" alt="BrightCherry Logo" />
<?
}
?>

If you use the above code, you will still see the image when you paginate to the second page of the homepage. If you strictly want it on the homepage, and no other pagination pages, you should use the following code:

1
2
3
4
5

<?
if (is_home() && strpos($_SERVER['REQUEST_URI'], "/page/") === false) {
?>
<img src="http://www.brightcherry.co.uk/images/logo.png" title="brightCherry Logo" alt="BrightCherry Logo" />
<?
}
?>

Now the image will only appear on the homepage
