It works there if the files are named correctly because the parent theme correctly loads … Read more

The actual encoding and decoding is done by your browser. When you write a post, your browser sends the text you just entered as UTF-8 to the … Read more
Save yourself a headache and make a class. The static variable can be accessed like a global once it’s loaded.

Yes, a database query is possible with WordPress: function is_image_in_network( $image_name ) { global $wpdb; $image = “uploads/2012/01/{$image_name}”; $value=”%”.like_escape( $image ).’%’; $blog_id = get_current_blog_id(); $wpdb->set_blog_id( $blog_id ); $image = $wpdb->get_var( $wpdb->prepare( “SELECT ID FROM {$wpdb->posts} WHERE post_status=”publish” AND post_content LIKE ‘%s'” , $value ) ); return is_null( $image ) ? false : true; } You … Read more
It is a long question but it is possible for some developers I would like to give this answer. Example: I have two choose for my home layout Grid and List and I prefer Grid is default choosing. I should add default value in add_setting simple like this ‘default’ => ‘grid’. $wp_customize->add_setting(‘yourtheme_home_layout_style’, array( ‘sanitize_callback’ => … Read more
