I have a wordpress website with customs posts and metas boxes.
One of these manage some pictures and I want to force the title of the post.
It should be the same as the name of the media uploaded.
Is it possible ? And how ?
Thank's
Manipulate the post title with a filter.
function change_post_title( $title, $id = null ) {
if ( is_single() ) {
$title = 'new title';
}
return $title;
}
add_filter( 'the_title', 'change_post_title', 10, 2 );
Thanks all for your help.
I have used a filter but this one :
function modify_post_title($data){
if($data['post_type'] == 'fcfm_photos' && isset($_POST['image'])) {
$data['post_title'] = substr($_POST['image'], -(strpos(strrev($_POST['image']),'/')));
}
return $data;
}
add_filter( 'wp_insert_post_data' , 'modify_post_title' , '99', 1 );
And when I save the post, the post title change automatically. This is what i want.

on my wordpress page I have a gallery which displays featured images.
I would like to add HTML to a specific item, using the wordpress functions file.
If I run the following code:
add_filter( 'post_thumbnail_html', 'add_featured_image_html', 10, 1 );
function add_featured_image_html( $html ) {
return $html .= '<p>'.get_the_ID().' is the ID</p>';
}
My frontend does display the post ID's underneath my thumbnails. In this case, I would like to target Post_ID 19 (btw this is a custom post type).
If I extend my code to:
$id = get_the_ID();
if ($id == 19) {
add_filter( 'post_thumbnail_html', 'add_featured_image_html', 10, 1 );
function add_featured_image_html( $html ) {
return $html .= '<p>'.get_the_ID().' is the ID</p>';
}
}
Nothing is displayed.
Is there someone that could help me out? thanks a million!
The second parameter of this filter is the post id. https://developer.wordpress.org/reference/hooks/post_thumbnail_html/
This isn't tested yet, because I'm on my phone... But this should work.
add_filter( 'post_thumbnail_html', 'add_featured_image_html', 10, 2 );
function add_featured_image_html( $html , $id) {
if ($id == 19){
return $html .= '<p>'.get_the_ID().' is the ID</p>';}
else {return $html}
}
What I want to have is that every new product will have the default title like this: shoe Size 10
Because there will be add many products everyday it would be much easier to have that as a default product title. Does someone have a code for this or can someone help me out with this?
You can use "Secondary title plugin". Instructions on link below secondary title plugin
Try This Method
add_product( 'the_title', 'product_title');
function product_title( $title, $id ) {
if ( is_shop() && get_post_type( $id ) === 'product' ) {
return ( $title);
} else {
return $title;
}
}
I want to add a product short description by default whenever is the new product is being created. All the products will have the same short description, so there is no point keep copying and pasting it. So it should just be there when I click on the add a new product.
I would appreciate any help.
add_filter( 'woocommerce_short_description',
'single_product_short_description', 10, 1 );
function single_product_short_description( $post_excerpt )
{
global $product;
if ( is_single( $product->id ) )
$post_excerpt = '<div class="product-message"><p>' . __( "Article only
available in the store.", "woocommerce" ) . '</p></div>' . $post_excerpt;
return $post_excerpt;
}
I found the above code but couldn't get it to work :(
Thank you.

Emre.
Add this code inside your themes function.php
Change the short description content as per your need - "Here goes your short desc."
add_filter( 'wp_insert_post_data' , 'cdx_add_product_short_desc' , '99', 1 );
function cdx_add_product_short_desc( $data )
{
//only for product post type
if($data['post_type'] == 'product' ) {
//only if short description is not present
if( '' == trim($data['post_excerpt']) ):
$short_desc = 'Here goes your short desc.';
$data['post_excerpt'] = $short_desc ;
endif;
}
// Returns the modified data.
return $data;
}
This will work to automatically override anything put into a product's short description field on the front-end only. It will not add the text to the backend field itself, which is good because it keeps it globalized if you need to change it later.
add_filter( 'woocommerce_short_description', 'filter_woocommerce_short_description', 10, 1 );
function filter_woocommerce_short_description( $post_excerpt ) {
$post_excerpt = '<div class="product-message"><p>' . __( "Article only available in the store.", "woocommerce" ) . '</p></div>';
return $post_excerpt;
}
I would like to know how to remove the word "archives" from a category or tag page title of a WordPress theme? Thank you!
Look at the official docs of get_the_archive_title(). You can modify the content through filter like below.
add_filter( 'get_the_archive_title', function ( $title ) {
if( is_category() ) {
$title = single_cat_title( '', false );
}
return $title;
});
This is a self Q&A.
How do you modify the text/html that appears in the output of a wp_nav_menu? For example, I wanted to add the featured image for pages and categories.
You see examples of doing this with a custom walker, but the code is very complex to do for small changes. Surely there is a way to do it with a filter?
This is the code I came up with thanks to some help from a Wordpress StackOverflow answer that I can't find anymore (please comment with a link if you find it).
First you need to add the filter to the specific menu (you could add it to all menus if you want - just use the add_filter line by itself).
// Add filter to specific menus
add_filter('wp_nav_menu_args', 'add_filter_to_menus');
function add_filter_to_menus($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;
}
