/*
* Add categories to pages
*/
function add_cats_to_pages_definition()
{
register_taxonomy_for_object_type('category', 'page');
}
add_action('init', 'add_cats_to_pages_definition');To set up default post categories for custom post types, please install plugin “Pods – Custom Content Types and Fields”
How it works:
Using hook set_object_terms anytime the categories are updated, this function will check whether they belong to a parent category and select the parent categories as well (and parent of parent, etc).
Note:
Do not use save_post to update categories.. because when you save a post where you only update the categories.. the save_post hook is not called.
add_action( 'set_object_terms', 'auto_set_parent_terms', 9999, 6 );
/**
* Automatically set/assign parent taxonomy terms to posts
*
* This function will automatically set parent taxonomy terms whenever terms are set on a post,
* with the option to configure specific post types, and/or taxonomies.
*
*
* @param int $object_id Object ID.
* @param array $terms An array of object terms.
* @param array $tt_ids An array of term taxonomy IDs.
* @param string $taxonomy Taxonomy slug.
* @param bool $append Whether to append new terms to the old terms.
* @param array $old_tt_ids Old array of term taxonomy IDs.
*/
function auto_set_parent_terms( $object_id, $terms, $tt_ids, $taxonomy, $append, $old_tt_ids ) {
/**
* We only want to move forward if there are taxonomies to set
*/
if( empty( $tt_ids ) ) return FALSE;
/**
* Set specific post types to only set parents on. Set $post_types = FALSE to set parents for ALL post types.
*/
$post_types = array( 'post' );
if( $post_types !== FALSE && ! in_array( get_post_type( $object_id ), $post_types ) ) return FALSE;
/**
* Set specific post types to only set parents on. Set $post_types = FALSE to set parents for ALL post types.
*/
$tax_types = array( 'category' );
if( $tax_types !== FALSE && ! in_array( get_post_type( $object_id ), $post_types ) ) return FALSE;
foreach( $tt_ids as $tt_id ) {
$parent = wp_get_term_taxonomy_parent_id( $tt_id, $taxonomy );
if( $parent ) {
wp_set_post_terms( $object_id, array($parent), $taxonomy, TRUE );
}
}
}If you want to simply get rid of all shortcodes in excerpts, try this:
add_filter('pre_excerpt_content', 'shortcodes_trim');
function shortcodes_trim($content) {
$content = preg_replace('/\[.*?\]/s', '', $content);
return $content;
}
For Divi Page Builder, use this:
add_filter('pre_excerpt_content', 'trim_divi_shortcodes');
function trim_divi_shortcodes($content) {
$content = preg_replace('/\[\/?et_pb.*?\]/', '', $content);
return $content;
}
For Visual Composer, use this:
add_filter('pre_excerpt_content', 'trim_vc_shortcodes');
function trim_vc_shortcodes($content) {
$content = preg_replace('/\[\/?vc.*?\]/', '', $content);
$content = preg_replace('/\[\/?mk.*?\]/', '', $content);
return $content;
}
Normally the get_the_content() tag returns the content without formatting. I found out a solution to make get_the_content() tag return the same content as the_content().
For me and others that can be a problem if you expect them to behave the same. I looked into the WordPress core and found a solution. Put this code into your functions.php in your theme folder.
function get_the_content_with_formatting ($more_link_text = '(more...)', $stripteaser = 0, $more_file = '') {
$content = get_the_content($more_link_text, $stripteaser, $more_file);
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
return $content;
}
In your theme, call the function within the loop:
function wpb_new_contactmethods( $contactmethods ) {
// Add Twitter
$contactmethods['twitter'] = 'Twitter';
//add Facebook
$contactmethods['facebook'] = 'Facebook';
return $contactmethods;
}
add_filter('user_contactmethods','wpb_new_contactmethods',10,1);
