How to create a directory within the uploads folder

April 23, 2013 at 6:23 pm

When developing a plugin or theme, it can be useful to be able to programmatically create a directory within the wp-content/uploads folder. Here is a handy piece of code to do it.

Simply paste this code snippet on your functions.php file (or plugin file if you’re creating a plugin)

function myplugin_activate() {
    $upload = wp_upload_dir();
    $upload_dir = $upload['basedir'];
    $upload_dir = $upload_dir . '/mypluginfiles';
    if (! is_dir($upload_dir)) {
       mkdir( $upload_dir, 0700 );
register_activation_hook( __FILE__, 'myplugin_activate' );

How to display an author bio excerpt on your WordPress blog

April 16, 2013 at 3:52 pm

WordPress offers users the option to add biographical info for each author. This bio can be displayed on your theme using the the_author_meta( ‘description’ ) function. But what if you’d like to display only a bio excerpt? Here’s a function to do it.

The first thing to do is to create the function. To do so, paste the following code into your functions.php file:

	function author_excerpt (){	                     					
		$word_limit = 20; // Limit the number of words
		$more_txt = 'read more about:'; // The read more text
		$txt_end = '...'; // Display text end 
		$authorName = get_the_author();
		$authorUrl = get_author_posts_url( get_the_author_meta('ID'));
		$authorDescription = explode(" ", get_the_author_meta('description'));
		$displayAuthorPageLink = count($authorDescription) > $word_limit ? $txt_end.'<br /> '.$more_txt.' <a href="'.$authorUrl.'">'.$authorName.'</a>' : '' ;
		$authorDescriptionShort = array_slice($authorDescription, 0, ($word_limit));
		return (implode($authorDescriptionShort, ' ')).$displayAuthorPageLink; 		

Once done, simply call the function when needed, as shown below:

<?php  if (function_exists('author_excerpt')){echo author_excerpt();} ?>

How to detect a comments page on your WordPress blog

April 15, 2013 at 4:04 pm

On WordPress dashboard, there’s an option to divide comments lists in sub pages. Unfortunately, there’s no built-in conditional tag to know if you’re currently on a comment page. So let’s built one!

Simply put the following code anywhere on your theme files. If you’re on a comment page, the conditional statement will return true, so any code within brackets will be executed.

$cpage = get_query_var( 'cpage' );
if ( is_singular() && $cpage > 0 ){
    // Your code here

This code works on posts, pages, attachments as well as all custom post_types.

How to directly include Typekit fonts on your WordPress theme

Typekit is a useful service which allow you to use countless different fonts on your website or blog. They do provide a WordPress plugin to easily add their fonts to your WordPress site, but there’s no built-in solution for integrating Typekit fonts directly to your theme. Here’s a recipe to do it.

Edit the code below and update the .js file path on line 2. Then, simple paste it on your functions.php file. Save the file, and you’re done!

function theme_typekit() {
    wp_enqueue_script( 'theme_typekit', '//');
add_action( 'wp_enqueue_scripts', 'theme_typekit' );

function theme_typekit_inline() {
  if ( wp_script_is( 'theme_typekit', 'done' ) ) { ?>
  	<script type="text/javascript">try{Typekit.load();}catch(e){}</script>
<?php }
add_action( 'wp_head', 'theme_typekit_inline' );
