5 Useful WordPress Functions For Functions.php!

Lately, I have been diving into a few awesome WordPress projects that involve some very specific customizations and queries. I'm going to make a mini post series this week and next that involve some helpful code that wasn't easy to find around the web that has helped me do a lot of these customizations!

I will start out this mini post series with some helpful function.php snippets that are not always easy to find. These are all some functions that would go in the functions.php WordPress theme file. Hopefully these help you and save you some time searching around the web! Enjoy! :)

1. Only allow specific tags in WordPress comments

// only allow <strong>, <em>, pre, code, and <a href=""> tags add_action('init', 'my_html_tags_code', 10); function my_html_tags_code() { define('CUSTOM_TAGS', true); global $allowedposttags, $allowedtags; $allowedposttags = array( 'strong' => array(), 'em' => array(), 'pre' => array(), 'code' => array(), 'a' => array( 'href' => array (), 'title' => array () ) ); $allowedtags = array( 'strong' => array(), 'em' => array(), 'pre' => array(), 'code' => array(), 'a' => array( 'href' => array (), 'title' => array () ) ); }

2. Detect the browser or device being used and add a class to "Body"

// Add - Browser Detection Body Class add_filter('body_class','lh_browser_body_class'); function lh_browser_body_class($classes) { global $is_lynx, $is_gecko, $is_IE, $is_opera, $is_NS4, $is_safari, $is_chrome, $is_iphone; if($is_lynx) $classes[] = 'lynx'; elseif($is_gecko) $classes[] = 'gecko'; elseif($is_opera) $classes[] = 'opera'; elseif($is_NS4) $classes[] = 'ns4'; elseif($is_safari) $classes[] = 'safari'; elseif($is_chrome) $classes[] = 'chrome'; elseif($is_IE) $classes[] = 'ie'; else $classes[] = 'unknown'; if($is_iphone) $classes[] = 'iphone'; return $classes; }

3. Make WordPress automated emails a custom "from" email other than the default.

// Custom "from" email function res_fromemail($email) { $wpfrom = get_option('admin_email'); return $wpfrom;} function res_fromname($email){ $wpfrom = get_option('blogname'); return $wpfrom;} add_filter('wp_mail_from', 'res_fromemail'); add_filter('wp_mail_from_name', 'res_fromname');

4. Hide new WordPress admin bar.

// Lose New WordPress Admin Bar add_filter('show_admin_bar', '__return_false');

5. Change the default WordPress excerpt length.

// Excerpt Length function my_excerpt_length($length) {return 20;} // 20 sets the number of characters add_filter('excerpt_length', 'my_excerpt_length');

QUICK TIP: Setting up your functions.php file.

<?php // // ↑ // Place any of the above functions in here! :) // ↓ // ?>

I hope this helps you guys! Please let me know (via the comments or Twitter) if you have any questions about them or need help using them! Thanks! :)
