Code in a functions.php (or any file loaded by that file) should not run automatically, eg. when the file is included. All code should be bound to hooks. That means, you don’t need a special action in the parent theme. The child theme can turn off all parent theme callbacks with remove_action() and remove_filter(). But … Read more
In your theme’s functions.php file you can add add_image_size( ‘thumb’, 600, 350, true ); add_image_size( ‘thumbnil’, 600, 350, true ); add_image_size( ‘medium’, 600, 350, true ); add_image_size( ‘large’, 600, 350, true ); add_image_size( ‘post-thumbnail’, 600, 350, true ); add_image_size( ‘{custom-image-type}’, 600, 350, true ); For more information have a look at http://codex.wordpress.org/Function_Reference/add_image_size
When accepting user data inputs, I think that data validation must be performed if possible, not only sanitization. For example, you could expect a number, a bool value, a text string (even when the input is a selectbox it can have a string value), etc. You can santize for that data types; then you can … Read more
Your theme should not depends on any external link library. There is no guarantee when that library can be taken down. That’s the reason all of your theme assets should be package with theme, to prevent the future risk.
It’s because that’s not how you should include an SVG in PHP, include_once is used for including PHP files. Reason behind this error: PHP Parse error: syntax error, unexpected version (T_STRING) is that PHP was unable to parse the beginning of the SVG file at the point where the XML version was defined: <?xml version=”1.0″ … Read more

Technically featured image is custom field with name _thumbnail_id that holds attachment ID. So you can easily query with something like: $args = array( ‘meta_query’ => array( array( ‘key’ => ‘_thumbnail_id’, ) ) ); $query = new WP_Query( $args ); Size on other hand is attribute of that attachment and not post itself. You will … Read more
There is a lot of leftovers in script-related articles in Codex that are not entirely correct (putting it mildly). The enqueue should not be done before wp_head(), it should be done on wp_enqueue_scripts. Which is technically early inside wp_head(). It doesn’t harm performance, because registering/enqueueing script is merely explaining to WordPress how it should be … Read more
