I’ve created a field group called ‘main_image’ and under it I have 2 fields
1.
‘main_image_logged’
type: image
2.
‘main_image_logout’
type:image
what im trying to do is to show the classic featured image which comes with the post for all, and for users that is logged in show the image in field “main_image_logged’
for the logout i even tried to set name:_thumbnail_id which took the image from ‘main_image_logout’ and used it as a featured image.
is there any way how to do this?
if user is logged out -> featured image from field ‘main_image_logout’
if user is logged in -> featured image from field ‘main_image_logged’
tried something like this but it's wrong
function acf_set_featured_image( $value, $post_id, $field ){
if (is_user_logged_in()) {
if($value != ''){
//Add the value which is the image ID to the _thumbnail_id meta data for the current post
add_post_meta($post_id, '_thumbnail_id', $value);
}
return $value;
}
}
add_filter('acf/update_value/name=main_image_logged', 'acf_set_featured_image', 10, 3);
using:
Wordpress
Advanced custom fields
Divi theme
thanks alot guys
Try this
add_filter('post_thumbnail_id', 'replace_thumbnail_id_with_acf', 20, 2);
function replace_thumbnail_id_with_acf($thumbnail_id, $post) {
if ( is_user_logged_in() ) {
$image_id = get_field('reveal_face', $post->ID, false);
if ($image_id) {
$thumbnail_id = $image_id;
}
} else {
$image_id = get_field('_thumbnail_id', $post->ID, false);
if ($image_id) {
$thumbnail_id = $image_id;
}
}
return $thumbnail_id;
}

I'm working on an index page that lists all posts for a custom post type. I've been listing the categories for each post using <?php echo strip_tags(get_the_term_list( $post->ID, 'genre', ' ',' • ')); ?>.
We need to add sub-categories but I don't want these to display on the index page - just the parent category. Have tried using get_term_parents_list and a few other examples from here but can't get anything working.
Can anyone help?
You can use get_the_terms filter to change the terms to return.
add_filter('get_the_terms', 'only_parent_genre', 10, 3);
function only_parent_genre($terms, $post_id, $taxonomy) {
// TODO for you : Add condition to heck if you are not on your custom index too.
if(is_admin() || $taxonomy !== 'genre') {
return $terms;
}
// Loop over terms and if parent is something different than 0, it means that's its a child term
foreach($terms as $key => $term) {
if($term->parent !== 0) {
unset($terms[$key]);
}
}
return $terms;
}
I have a wordpress website where customers make an image with text and icons, once processed thru woocommerce and payed for that image name 12345.png is saved as Customer_product_image
function add_order_item_meta($item_id, $values) {
$key = 'customer_product_image'; // Define your key here
$value = $values['user_img']; // Get your value here
woocommerce_add_order_item_meta($item_id, $key, $value);
}
And i works great, but now i'm banning my head against the wall! When the purchased image is displayed on the Order admin detail page, it shows up as CUSTOMER_PRODUCT_IMAGE: 1234.png how on earth would i go about wrapping that within an image tag so the image is displayed there?
I've searched high and low on google but haven't been able to find anything, its probably that i dont know what do actually search for....
This did the trick for me!
First i added this snippet for removing the custom meta item on order detail render:
add_filter( 'woocommerce_hidden_order_itemmeta', 'hide_order_item_meta_fields' );
function hide_order_item_meta_fields( $fields ) {
$fields[] = 'current_view';
$fields[] = 'custom_image';//Add all meta keys to this array,so that it will not be displayed in order meta box
return $fields;
}
second i added it back with this, and with the desired text and image tag:
add_action( 'woocommerce_after_order_itemmeta', 'order_meta_customized_display',10, 3 );
function order_meta_customized_display( $item_id, $item, $product ){
$all_meta_data=get_metadata( 'order_item', $item_id, "", "");
$useless = array(
"_qty","_tax_class","_variation_id","_product_id","_line_subtotal","_line_total","_line_subtotal_tax","_line_tax","_line_tax_data"
);// Add key values that you want to ignore
$customized_array= array();
foreach($all_meta_data as $data_meta_key => $value) {
if(!in_array($data_meta_key,$useless)){
$newKey = ucwords(str_replace('_'," ",$data_meta_key ));//To remove underscrore and capitalize
$customized_array[$newKey]=ucwords(str_replace('_'," ",$value[0])); // Pushing each value to the new array
}
}
if (!empty($customized_array)) {
foreach($customized_array as $data_meta_key => $value){
echo "<div class='product_container'><span>Produkt Billede: </span><img src='".wp_upload_dir()['baseurl'].'/flapper/'. $value ."' /> </div>";
}
}
}
i found the answer to this question on this page
You can use the filter woocommerce_order_item_display_meta_value to output the image. Place this code in your functions.php file, you'll need to modify the src attribute of the img tag to include the appropriate URL before the filename value. You can also modify the display label with the filter woocommerce_order_item_display_meta_key
add_filter( 'woocommerce_order_item_display_meta_value', 'modify_order_item_display_value' , 10, 3 );
function modify_order_item_display_value( $display_value, $meta, $wc_order_item ) {
$meta_data = $meta->get_data();
if( $meta_data['key'] === 'customer_product_image' ) {
return '<img src="' . $meta_data['value'] . '">';
}
return $display_value;
}
add_filter('woocommerce_order_item_display_meta_key', 'modify_order_item_display_key', 10, 3);
function modify_order_item_display_key( $display_key, $meta, $wc_order_item ) {
$meta_data = $meta->get_data();
if( $meta_data['key'] === 'customer_product_image' ) {
return 'Customer Image';
}
return $display_key;
}
This is a self Q&A.
How do you modify the text/html that appears in the output of a wp_nav_menu? For example, I wanted to add the featured image for pages and categories.
You see examples of doing this with a custom walker, but the code is very complex to do for small changes. Surely there is a way to do it with a filter?
This is the code I came up with thanks to some help from a Wordpress StackOverflow answer that I can't find anymore (please comment with a link if you find it).
First you need to add the filter to the specific menu (you could add it to all menus if you want - just use the add_filter line by itself).
// Add filter to specific menus
add_filter('wp_nav_menu_args', 'add_filter_to_menus');
function add_filter_to_menus($args) {
// You can test agasint things like $args['menu'], $args['menu_id'] or $args['theme_location']
if( $args['theme_location'] == 'header_menu') {
add_filter( 'wp_setup_nav_menu_item', 'filter_menu_items' );
}
return $args;
}
Then you need to build out the code to get the post or category ID from the $item object passed to the filter. It's not as easy as you'd expect, as $item doesn't contain the underlying post/category ID, just the menu item ID. So I use the URL's to do a reverse lookup of the IDs.
This won't work for tags used in a menu, or custom taxonomys. I only needed it for categories, so this is all I built.
// Filter menu
function filter_menu_items($item) {
if( $item->type == 'taxonomy') {
// For category menu items
$cat_base = get_option('category_base');
if( empty($cat_base) ) {
$cat_base = 'category';
}
// Get the path to the category (excluding the home and category base parts of the URL)
$cat_path = str_replace(home_url().'/'.$cat_base, '', $item->url);
// Get category and image ID
$cat = get_category_by_path($cat_path, true);
$thumb_id = get_term_meta($cat->term_id, '_term_image_id', true); // I'm using the 'Simple Term Meta' plugin to store an attachment ID as the featured image
} else {
// Get post and image ID
$post_id = url_to_postid( $item->url );
$thumb_id = get_post_thumbnail_id( $post_id );
}
if( !empty($thumb_id) ) {
// Make the title just be the featured image.
$item->title = wp_get_attachment_image( $thumb_id, 'poster');
}
return $item;
}
And then you want to remove the filter that you applied at the beginning, so that the next menu processed doesn't use the same HTML as defined above in filter_menu_items().
// Remove filters
add_filter('wp_nav_menu_items','remove_filter_from_menus', 10, 2);
function remove_filter_from_menus( $nav, $args ) {
remove_filter( 'wp_setup_nav_menu_item', 'filter_menu_items' );
return $nav;
}
Modified Drew Baker answer. It works without plugins, also if there is no category with current slug it checks for woocommerce product category ('product_cat').
functions.php
// Add filter to specific menus
add_filter('wp_nav_menu_args', 'add_filter_to_menus');
function add_filter_to_menus($args) {
// You can test agasint things like $args['menu'], $args['menu_id'] or $args['theme_location']
if( $args['theme_location'] == 'menu-header') {
add_filter( 'wp_setup_nav_menu_item', 'filter_menu_items' );
}
return $args;
}
// Filter menu
function filter_menu_items($item) {
if( $item->type == 'taxonomy') {
// Get category and image ID
$slug = pathinfo( $item->url, PATHINFO_BASENAME );
$cat = get_term_by( 'slug', $slug, 'category' );
// If there is no standard category try getting product category
if( !$cat ) {
$cat = get_term_by( 'slug', $slug, 'product_cat' );
}
$thumb_id = get_term_meta($cat->term_id, 'thumbnail_id', true);
} else {
// Get post and image ID
$post_id = url_to_postid( $item->url );
$thumb_id = get_post_thumbnail_id( $post_id );
}
if( !empty($thumb_id) ) {
// Make the title just be the featured image.
$item->title = wp_get_attachment_image( $thumb_id, 'poster');
// Display image + title example
// $item->title = wp_get_attachment_image( $thumb_id, 'poster').$item->title;
}
return $item;
}
// Remove filters
add_filter('wp_nav_menu_items','remove_filter_from_menus', 10, 2);
function remove_filter_from_menus( $nav, $args ) {
remove_filter( 'wp_setup_nav_menu_item', 'filter_menu_items' );
return $nav;
}
Using filters/hooks, how would I replace the title of a wordpress post with whatever term has been selected from a custom taxonomy.
Hopefully the attached image will explain what I'm trying to do.
Let's say I selected 'Powerchrono' - I would like the title of the post to be replaced with the selected term, and it's parent.
Any help would be much appreciated.
I'd obviously like the url of the post to also be updated too.
I can't guarantee this will work straight out of the gate since it's untested. But this should get you started:
functions.php
<?php
add_action('save_post', 'update_term_title');
function update_term_title($post_id)
{
if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return;
if(!current_user_can('edit_post', $post_id))
return;
//Replace 'manufacturer' with whatever your custom taxonomy slug is
$terms = wp_get_post_terms($post_id, 'manufacturer');
if(empty($terms))
return;
$title = false;
foreach($terms as $term)
{
if($term->parent)
{
$parent = get_term($term->parent, 'manufacturer');
$title = $term->name.' '.$parent->name;
break;
}
}
/*Default to first selected term name if no children were found*/
$title = $title ? $title : $terms[0]->name;
/*We must disable this hook and reenable from within
if we don't want to get caught in a loop*/
remove_action('save_post', 'update_term_title');
$update = array(
'ID'=>$post_id,
'post_name'=>sanitize_title_with_dashes($title),
'post_title'=>$title
);
wp_update_post($update);
add_action('save_post', 'update_term_title');
}
?>
I am using the FeedWordPress plugin http://wordpress.org/extend/plugins/feedwordpress/ to pull posts from one site to another.
I have written a filter that after some help from Stack users successfully scans the $content and extracts the image URL into $new_content
define('FWPASTOPC_AUTHOR_NAME', 'radgeek');
add_filter(
/*hook=*/ 'syndicated_item_content',
/*function=*/ 'fwp_add_source_to_content',
/*order=*/ 10,
/*arguments=*/ 2
);
function fwp_add_source_to_content ($content, $post) {
// Use SyndicatedPost::author() to get author
// data in a convenient array
$content = $post->content();
// Authored by someone else
if( preg_match( '/<img[^>]+src\s*=\s*["\']?([^"\' ]+)[^>]*>/', $content, $matches ) ) {
$new_content .= 'URL IS '.$matches[0].'';
return $new_content;
}
else
{
}
}
What I wanted to do now was save this URL into a custom field instead of just returning it. Has anyone achieved anything similar?
So as I understand it, the plugin grabs content from external RSS feeds and creates them as posts in your website.
If this is the case, using your filter you should be able to grab the post ID within the $post variable.
So all you need is the add_post_meta() function to add a custom field to the specific post.
So including your code above it should look something like:
define('FWPASTOPC_AUTHOR_NAME', 'radgeek');
add_filter(
/*hook=*/ 'syndicated_item_content',
/*function=*/ 'fwp_add_source_to_content',
/*order=*/ 10,
/*arguments=*/ 2
);
function fwp_add_source_to_content ($content, $post) {
// Use SyndicatedPost::author() to get author
// data in a convenient array
$content = $post->content();
// Authored by someone else
if( preg_match( '/<img[^>]+src\s*=\s*["\']?([^"\' ]+)[^>]*>/', $content, $matches ) ) {
$new_content .= 'URL IS '.$matches[0].'';
//Add custom field with author info to post
add_post_meta($post->ID, 'post_author', $new_content);
return $new_content;
}
}
