All good examples. But they weren’t working for me with the theme (pinboard) and plugin I was using (secondary-html-content) and what I wanted to do. The first challenge was to make sure that I get both pieces of content instead of just one. The second challenge was to replace the excerpt on the homepage with … Read more
add a filter to sanitize_file_name: function wpse27657_filename_filter($name) { return time().$name; } add_filter(‘sanitize_file_name’, ‘wpse27657_filename_filter’, 10);
Taking a stab at a general answer, since we don’t (yet?) have access to the specific Theme. Note: all of these edits can – and perhaps should – be implemented via Child Theme. First, you need to remove ALL of those lines from header.php. Scripts should be enqueued, rather than hard-coded into the template. Then, … Read more
pre_get_posts hook should work for this: add_action( ‘pre_get_posts’, ‘wpse35832_pre_get_posts’ ); function wpse35832_pre_get_posts( $wp ){ if( $wp->query_vars[‘p’] == 200 ): $wp->query_vars[‘p’] = 100; endif; return $wp; } It may work a bit differently if pretty permalinks are used, different query vars may be set, not sure though.
You’re doing several things wrong, and they’re all silly, avoidable, basic logic mistakes. Firstly, you’re not checking if this is an autosave. Autosaves do not save the custom fields, only the original core wordpress fields, like content, so an autosave will giv eyou unset/blank values. Add this to the top of your save function: if … Read more
wp_enqueue_scripts is only fired on the front end, and not on admin screens. For loading scripts admin side, you’ll want the hook admin_enqueue_scripts. Passed as an optional argument is the page hook. (Examples include edit.php, for the admin edit page (which lists pages/posts/ cpt posts), post.php when editing a post/ custom post type and post-new.php … Read more
register_deactivation_hook() is launched when a plugin is deactivated. For plugin uninstall, there is register_uninstall_hook(). WordPress plugins can also have a file called uninstall.php that is ran whenever the plugin is uninstalled. To prevent the uninstall.php file from being triggered directly, the state of a constant called WP_UNINSTALL_PLUGIN should be checked before launching the codes for … Read more
You cannot hook in a function without a hook. If it returns a variable, you will have to use it as it is returned. And then, maybe, perform your operations on that.
Try adding this to your theme’s function.php. It worked for me, hope it helps. // PRETTY PHOTO // add_action( ‘wp_enqueue_scripts’, ‘lightbox’ ); function lightbox() { global $woocommerce; $suffix = defined( ‘SCRIPT_DEBUG’ ) && SCRIPT_DEBUG ? ” : ‘.min’; { wp_enqueue_script( ‘prettyPhoto’, $woocommerce->plugin_url() . ‘/assets/js/prettyPhoto/jquery.prettyPhoto’ . $suffix . ‘.js’, array( ‘jquery’ ), $woocommerce->version, true ); wp_enqueue_script( … Read more
You can only return one chunk of data from a function. That is a PHP enforced rule. If you need to return multiple pieces of data you need to return an array or an object. With filters, though, you can’t just decide what to return. You have to return what the filter is meant to … Read more
