There is a subtle difference between action hooks and filters. The most notable one is that filter functions are expected to receive a value and pass it along in return when done with their work. Inside the function the value can be modified or be used for something else. In your case the_content is a … Read more
Figured it out, hooking into content_save_pre: function remove_empty_lines( $content ){ // replace empty lines $content = preg_replace(“/ /”, “”, $content); return $content; } add_action(‘content_save_pre’, ‘remove_empty_lines’);
For this, you’ll actually want to utilize the wp_enqueue_scripts action instead of wp_head. wp_enqueue_scripts is technically the proper way to add scripts and styles to your site. This action allows us to both register scripts and styles for later use (which is what we want here) and allows us to output scripts and styles to … Read more
To output your content, It is advised that you pass your content through a filter. get_the_content() does not do this, so it will not for example execute shortcodes or create <p> tags. So, it would be better to use it this way: <?php echo apply_filters( ‘the_content’, wp_trim_words( get_the_content() , 70 ) ); ?> You can … Read more
To filter the content only when an auto-excerpt is generated you have to chain the hooks: Hook into get_the_excerpt and register a filter for the_content. In the second filter remove both elements and their content before the excerpt can see it. Sample: add_filter( ‘get_the_excerpt’, ‘t5_excerpt_clean_up’, 1 ); /** * Register handler for auto-generated excerpt. * … Read more
To update properties of a post in the database use wp_update_post. // Update post 37 $my_post = array( ‘ID’ => 37, ‘post_title’ => ‘This is the post title.’, ‘post_content’ => ‘This is the updated content.’, ); // Update the post into the database wp_update_post( $my_post ); Just beware of the possibility of an infinite loop … Read more
If you’re using a class, it would be class MyShortcode { static $instance = 0; function __construct($args = array()) { add_action( ‘init’, array(&$this, ‘init’) ); } function init() { add_shortcode(‘myshortcode’, array(&$this, ‘shortcode’)); } static function shortcode($atts) { //this is the code of your shortcode // you can increment your counter self::$instance++; } }
Double check that you don’t have a check for has_excerpt() that’s hiding the “auto-generated” excerpt. Even if get_the_excerpt() returns something made from post_content, has_excerpt() still returns false if the excerpt is empty. If that’s not the case, see if there’s a function that filters on get_the_excerpt that could be effecting this. To answer your question, … Read more
Since custom fields are kept in the meta table, you can proabably just remove this line: $c = str_replace(‘%points%’,cp_formatPoints(get_post_meta($post->ID,’cp_pcontent_points’, 1)),$c); Alternatively, you can use a boolean as a parameter to not run this line of code. HTH
echo $post->post_content; will echo your post content. Keep in mind though, it’s raw out of the database (same as get_the_content()). If you want to apply the same filters that the_content() receives, follow the instructions in the codex: <?php $content = apply_filters(‘the_content’, $content); $content = str_replace(‘]]>’, ‘]]>’, $content); ?>
