Note that to remove a filter callback from the woocommerce_email_content filter, you first need to have it registered via: add_filter( ‘woocommerce_email_content’, …some-custom-callback… ); but it looks like you’re trying to remove the inline styles from the message. I guess you need the text/html content type, so try instead to override the styles with (untested): add_filter( … Read more
You shouldn’t be putting arbitrary HTML into post content, instead use shortcodes! Shortcodes were intended for this situation. Otherwise you face 2 problems: Filters will escape your content via the wp_kses_post on output TinyMCE will filter/mangle/strip tags when you use the visual editor, even for the slightest of moments All of these are done for … Read more
I suggest post status transitions that runs only when your set conditions are met. Example: add_action( ‘transition_post_status’, ‘add_awesome_terms’, 10, 3 ); function add_awesome_terms( $new_status, $old_status, $post ) { // only run when it’s a page, new status is publish and old status isn’t publish if ( $post->post_type == ‘page’ && $new_status == ‘publish’ && $old_status … Read more
You need to make a custom query to display these pending posts. Here is an example using get_posts(): $args = array( ‘post_type’ => ‘post_type_name’, ‘post_status’ => ‘pending’, // -1 shows all ‘posts_per_page’ => -1, ); $pending_posts = get_posts( $args ); foreach( $pending_posts as $pending_post ) { // post object properties $id = $pending_post->ID; $title = … Read more
Use the $wp_scripts, which is a global variable to get the version of a registered script. add_filter( ‘script_loader_tag’, ‘script_handler’, 10, 3 ); function script_handler( $tag, $handle, $src ) { // the following global contains all the information you need global $wp_scripts; $ver = $wp_scripts->registered[ $handle ]->ver; // do your thing } Note, this is exemplary.
As you can see in the Codex, the filter actually has 2 arguments, which needs to be stated: add_filter( ‘the_title’, function ( $title, $id = null ) { return preg_replace(‘#(\s{3})#’, ‘…’, $title); }, 10, 2 ); You could as well just use a placeholder that you replace on the fly – might be easier. In case … Read more
The theme_page_templates filter is not available anymore, please use the theme_templates filter instead. add_filter( ‘theme_templates’, ‘filter_template_dropdown’ );
Ok, got it working. I was returning a property of a serialized option within the callbacks for the filters: add_filter(‘pre_option_page_on_front’, ‘page_on_front’); function page_on_front() { $options = get_option(‘theme_options’); return $options[‘page_on_front’]; } add_filter(‘pre_option_page_for_posts’, ‘page_for_posts’); function page_for_posts() { $options = get_option(‘theme_options’); return $options[‘page_for_posts’]; } The returend values were numbers, but strings. Typecasting them to int got it working.
Well it works the same in the case where you tested it. The answer could actually be somewhat complex, but mainly having it inside an action callback only registers them when needed, just putting it inside the functions.php it happens always when the theme is active. First of all this can be a waste of … Read more
If you are talking about excerpt set manually in the excerpt field of post then you can use following code in the functions.php file of your child theme or plugin to display default excerpt if no excerpt it set. function display_default_excerpt( $excerpt ) { if ( has_excerpt() ) { return $excerpt; } else { return … Read more
