Actually, I just did something like this for a Drupal site. I based my truncation function on this: Truncate text preserving HTML tags with PHP Use the final version of the function at the end of the comments. The function takes its $length parameter in characters, not words, but you can probably use the general … Read more
You mean you call your class right before closing HTML tag? It is too late to enqueue scripts then. Don’t hook into wp_print_scripts to enqueue your scripts and styles. I just learned this today from Rarst. So change your init_hooks function to something like following: public function init_hooks() { add_action(‘wp_enqueue_scripts’, array(__CLASS__,’include_all_files’)); } Also you are … Read more
Ok, just noticed that you’re wrapping the URL in single quotes, so the $username variable won’t get interpreted. Try this instead: wp_remote_get(‘https://twitter.com/statuses/user_timeline/’. $username .’.json’); Or use double quotes instead of single.
if you are asking default background image for add_theme_support( ‘custom-background’); then it can be set using ‘default-image’ => get_template_directory_uri() . ‘/images/pattern.png’, complete code will look like below. $args = array( ‘default-color’ => ‘f0f0f0’, ‘default-repeat’ => ‘fixed’, ‘default-image’ => get_template_directory_uri() . ‘/assets/images/pattern.png’, ); add_theme_support( ‘custom-background’, $args );
Instead of using jQuery to update the value of the custom input, use the wp.customize object’s set() function (found in customize-base.js): wp.customize( key, function ( obj ) { obj.set( newValue ); } ); Where key is the setting, and newValue is the updated value. Also, worth noting, in the class that extends WP_Customize_Control, make sure … Read more
After using the Chrome inspector on the “Appearance > Menus” categories panel I was able to sniff out the hidden form values that are passed when one manually adds a category to a custom menu via the wizard: <li> <label class=”menu-item-title”> <input type=”checkbox” class=”menu-item-checkbox” name=”menu-item[-11][menu-item-object-id]” value=”181″> Category One</label> <input type=”hidden” class=”menu-item-db-id” name=”menu-item[-11][menu-item-db-id]” value=”0″> <input type=”hidden” … Read more
Before we go into details, it should be noted that the guides you are referring to is only what it is, a guide. Just like coding standards (which not even the core developers stick to 🙂), the WordPress Handbook is just a guide to developers, it is not the alpha and omega. The basic idea … Read more
How often are the theme mods changed? A lot in the design phase, maybe a couple of times later on. Always by admins, never by ordinary users, let alone visitors. So, it doesn’t make sense to generate the full css at every pageload (additional background info). A better approach is to generate the css only … Read more
You have to change the defualt Site Icon using the Customizer API. $wp_customize->add_setting( ‘site_icon’ , array( ‘default’ => YOUR_IMAGE_URL_HERE, ) );
