i got this code from researching and trying to modify it but no luck. I want the last item in yoast breamcrumbs not to appear on single pages only
if ( is_single() ) {
/*Remove Last item in Yoast SEO Breadcrumb */
function adjust_single_breadcrumb( $link_output) {
if(strpos( $link_output, 'breadcrumb_last' ) !== false ) {
$link_output = '';
}
return $link_output;
}
add_filter('wpseo_breadcrumb_single_link', 'adjust_single_breadcrumb' );
};
I tried adding if is single in between the function and also this
if(strpos( $link_output, 'breadcrumb_last' ) !== false && is_single) {
unfortunately, the whole breadcrumb disappears.
with this code, you can remove post title in single page.
add_filter('wpseo_breadcrumb_single_link_info', 'remove_post_title_wpseo_breadcrumb', 10, 3);
function remove_post_title_wpseo_breadcrumb($link_info, $index, $crumbs)
{
if (is_singular() && isset($link_info['id']))
return [];
return $link_info;
}
Updated: In the latest version above code does not work perfectly.
for this reason, I removed the last item with regex:
function getBreadcrumb() {
if ( function_exists( 'yoast_breadcrumb' ) ) {
ob_start();
yoast_breadcrumb( '<p id="breadcrumb" class="meta-info">', '</p>' );
$breadcrumb = trim( ob_get_clean() );
if ( is_singular() )
$breadcrumb = trim( preg_replace( '/ ' . WPSEO_Options::get( 'breadcrumbs-sep' ) . ' <span class="breadcrumb_last" aria-current="page">(.*)<\/span>/i', '',
$breadcrumb ) );
echo $breadcrumb;
}
}
And call the function anywhere you want:
<?php getBreadcrumb() ?>

In Woocommerce 3.0 the single variation add to cart button is wrapped in a container div:
<div class="woocommerce-variation-add-to-cart variations_button">
// do_actions for before and after add_to_cart_quantity
</div>
I'd like to filter the html to remove the container div without overriding the variation-add-to-cart-button.php template file and without jquery/javascript.
Any help would be great!
Please try the following code. I haven't tested it but it supposed to work. Please try this on your dev environment first.
add_action( 'woocommerce_before_template_part', function( $template_name ) {
if ( 'single-product/add-to-cart/variation-add-to-cart-button.php' === $template_name ) {
ob_start();
}
} );
add_action( 'woocommerce_after_template_part', function( $template_name ) {
if ( 'single-product/add-to-cart/variation-add-to-cart-button.php' === $template_name ) {
$content = ob_get_clean();
$content = str_replace( '<div class="woocommerce-variation-add-to-cart variations_button">', '', $content );
$content = str_replace( '</div>', '', $content );
echo $content;
}
} );
I have a category called 'News'. The category ID is '20'. I am using the Divi (Divi child) theme + Wordpress and want to shorten the excerpt for the News category.
I typically would use the 'add_filter' function like this:
<pre>
add_filter('excerpt_length', 'news_excerpt_length');
function news_excerpt_length($length) {
if(in_category(20)) {
return 30;
} else {
return 60;
}
}
</pre>
But that ain't workin'. I found the excerpt control in the 'main-modules.php' and figure to add my filter here? Has anyone done this?
I added the 'main-module.php' to the root of my child theme and then added this to my child 'functions.php'
<pre>
if ( ! function_exists( 'et_builder_add_main_elements' ) ) :
function et_builder_add_main_elements() {
require ET_BUILDER_DIR . 'main-structure-elements.php';
require 'main-modules.php';
do_action( 'et_builder_ready' );
}
endif;
</pre>
It didn't break the theme, but it didn't work either. Does anyone have any experience with this particular issue?
-Thanks!
To override the post_excerpt lengh, you can find in custom_functions.php the function truncate_post()
if ( ! function_exists( 'truncate_post' ) ) {
function truncate_post( $amount, $echo = true, $post = '', $strip_shortcodes = false ) {
global $shortname;
if ( '' == $post ) global $post;
$post_excerpt = '';
$post_excerpt = apply_filters( 'the_excerpt', $post->post_excerpt );
if ( 'on' == et_get_option( $shortname . '_use_excerpt' ) && '' != $post_excerpt ) {
if ( $echo ) echo $post_excerpt;
else return $post_excerpt;
} else {
// get the post content
$truncate = $post->post_content;
// remove caption shortcode from the post content
$truncate = preg_replace( '#\[caption[^\]]*?\].*?\[\/caption]#si', '', $truncate );
// remove post nav shortcode from the post content
$truncate = preg_replace( '#\[et_pb_post_nav[^\]]*?\].*?\[\/et_pb_post_nav]#si', '', $truncate );
// Remove audio shortcode from post content to prevent unwanted audio file on the excerpt
// due to unparsed audio shortcode
$truncate = preg_replace( '#\[audio[^\]]*?\].*?\[\/audio]#si', '', $truncate );
if ( $strip_shortcodes ) {
$truncate = et_strip_shortcodes( $truncate );
} else {
// apply content filters
$truncate = apply_filters( 'the_content', $truncate );
}
// decide if we need to append dots at the end of the string
if ( strlen( $truncate ) <= $amount ) {
$echo_out = '';
} else {
$echo_out = '...';
// $amount = $amount - 3;
}
// trim text to a certain number of characters, also remove spaces from the end of a string ( space counts as a character )
$truncate = rtrim( et_wp_trim_words( $truncate, $amount, '' ) );
// remove the last word to make sure we display all words correctly
if ( '' != $echo_out ) {
$new_words_array = (array) explode( ' ', $truncate );
array_pop( $new_words_array );
$truncate = implode( ' ', $new_words_array );
// append dots to the end of the string
$truncate .= $echo_out;
}
if ( $echo ) echo $truncate;
else return $truncate;
};
}
}
You don't need to put if ( ! function_exists( 'truncate_post' ) ) { to make it work just create your function with the same name in functions.php
If you are using a child theme (I really hope so with a theme like this), copy/paste index.php and paste these lines, line 54
if(in_category(20)) {
truncate_post( 30 );
} else {
truncate_post( 60 );
}
It can be easier
Hope it helps
I ended up doing it ( although I don't know which solution is better ) by putting this in my 'main-module.php' starting on line 12319
// do not display the content if it contains Blog, Post Slider, Fullwidth Post Slider, or Portfolio modules to avoid infinite loops
if ( ! has_shortcode( $post_content, 'et_pb_blog' ) && ! has_shortcode( $post_content, 'et_pb_portfolio' ) && ! has_shortcode( $post_content, 'et_pb_post_slider' ) && ! has_shortcode( $post_content, 'et_pb_fullwidth_post_slider' ) ) {
if ( 'on' === $show_content ) {
global $more;
// page builder doesn't support more tag, so display the_content() in case of post made with page builder
if ( et_pb_is_pagebuilder_used( get_the_ID() ) ) {
$more = 1;
the_content();
} else {
$more = null;
the_content( esc_html__( 'read more...', 'et_builder' ) );
}
} else {
if ( has_excerpt() ) {
the_excerpt();
} else {
if(in_category(20)) {
echo wpautop( truncate_post( 70, false ) );
} else {
echo wpautop( truncate_post( 370, false ) );
}
}
}
} else if ( has_excerpt() ) {
the_excerpt();
}
The Challenge
I have been trying to write a filter that applies (prepends a string) to (a) post titles of a certain post type and (b) to that same post type WordPress admin backend for use by an auto social sharing plugin.
I've gotten really close. I've achieved:
1. prepending only to custom post_type post titles
2. prepending to custom_post type titles AND all nav menu items
3. prepending to ALL titles (post, page, nav menu, and backend auto-sharing plugin)
The final, 3rd attempt got me very hopeful, but yet still, no matter the function, conditional statement, or combination I use, I can't get custom_post title AND backend social sharing plugin, but not nav menu items.
My Code - what I've tried
I've tried different conditionals, like is_admin() and !is_nav_menu with all nav menu IDs. I've also tried comparing the ID of the post to the ID of the menu. Finally, I've also tried adding the filter only to loop_start and that seems promising if combined with other statements. I will clean up my code for your review but I leave it this way for now in hopes it helps to see what I've tried and maybe where I went wrong with any of those methods.
// , $id = NULL
function append_album_review_to_title( $title ) {
global $post;
global $dont_apply_title_filter;
$text = 'Album Review: ';
$prepended_title = $text . $title;
/*
$nav_menus_obj = wp_get_nav_menus();
$nav_menu_ids = '';
foreach( $nav_menus_obj as $nav_menu ) {
$nav_menu_ids .= $nav_menu->term_id . ',';
}
rtrim($nav_menu_ids, ',');
*/
// if ( get_post_type( $post->ID ) == 'album_review' && in_the_loop() ){
// if ( get_post_type( $post->ID ) == 'album_review' && $id == get_the_ID() ){
// if ( !is_nav_menu( '32057,32058,35135,32054,32056' ) ) {
// if ( get_post_type( $post->ID ) == 'album_review' && is_nav_menu( $id ) ) {
if ( get_post_type( $post->ID ) == 'album_review' && !$dont_apply_title_filter ) {
//print_r( $nav_menu_ids );
//print_r( is_nav_menu( $nav_menu_ids ) );
return $prepended_title;
/*
} elseif ( get_post_type( $post->ID ) == 'album_review' ) {
return $title;
*/
} else {
return $title;
};
}
add_filter('the_title', 'append_album_review_to_title');
//add_action('save_post', 'custom_post_type_title', 100);
/*
function set_custom_title() {
add_filter( 'the_title', 'append_album_review_to_title', 10, 2 );
}
add_action( 'loop_start', 'set_custom_title' );
*/
Solution
function append_album_review_to_title( $title, $id = NULL ) {
if ($id) {
if ( get_post_type( $id ) == 'album_review' ){
return 'Album Review: ' . $title;
} else {
return $title;
}
} else {
return 'Album Review: ' . $title;
};
}
add_filter('the_title', 'append_album_review_to_title', 10, 2);
Explanation
First trying this:
function append_album_review_to_title( $title, $id ) {
if ( get_post_type( $id ) == 'album_review' ){
return 'Album Review: ' . $title;
} else {
return $title;
}
}
add_filter('the_title', 'append_album_review_to_title', 10, 2);
I noticed that on the backend, the social sharing plugin I am using to auto-share posts would return warnings like missing parameter 2 and Notice: Trying to get property of non-object..., and so it occurred to me that unlike the front end (nav menu and the loop), in the backend, apparently an $id is not being passed to the_title and so I can use this as a conditional.
Checking for $id will, for my purposes, tell me that if it is true, we are on front end, if it is false, then we are at backend post view.
This code accomplishes what I need (ie, modify post title in the loop, do NOT modify nav menu items, and modify the_title for use by a backend social sharing plugin):
Entirely Revised Please Reread
Hello,
The theme I am using displays the page's title as opposed to it's menu label in the breadcrumbs. I am trying to get the breadcrumbs to instead display the associated menu label if it is available and if not then default to the page_title.
I have come up with some code that I think is close. Line 4/// $menu_items = wp_get_nav_menu_items( $slug ); returns null and it should return the nav item that contains $slug of the current post. Obviously, there is something I do not understand.
What I am attempting to do is get the slug of the current post, then using the slug get the nav item post. Then extract the title of the nav item and use that in place of the page title in the breadcrumbs. If the page was not in the nav system then it should default to the page title, as might be the case for a ppc campaign landing page.
if ( is_page() && !$post->post_parent ) {
$title = null;
$slug = mpactMEDIA_get_the_slug( get_the_ID() );
$menu_items = wp_get_nav_menu_items( $slug );
//var_dump((array)$menu_items);
foreach ( (array)$menu_items as $key => $menu_item ) {
$title = $menu_item->post_title;
}
if ( $title ) { echo $delimiter . ' ' . $before . $title . $after; }
else { echo $delimiter . ' ' . $before . get_the_title() . $after; }
}
I'm my functions.php file I have the following function
function mpactMEDIA_get_the_slug( $id=null ){
if( empty($id) ) global $post;
if( empty($post) ) return '';
$id = $post->ID;
endif;
$slug = basename( get_permalink($id) );
return $slug;
}
Thank you in advance,

I read the question a few times, I got here searching for an answer, ended up making my own.
function get_menu_label_by_post_id($post_id, $menu) {
$menu_title = '';
$nav = wp_get_nav_menu_items($menu);
foreach ( $nav as $item ) {
if ( $post_id == $item->object_id ) {
$menu_title = $item->post_title;
break;
}
}
return ($menu_title !== '') ? $menu_title : get_the_title($post_id);
}
Example usage:
echo get_menu_label_by_post_id($post->ID, 'Primary Nav');
This will return what the menu label is if it finds it, otherwise just the title of the post ID.
Check the documentation for wp_get_nav_menu_items. It doesn't take a page slug as a parameter at all.
If you want to list child pages of a given page, use wp_list_pages and pass a child_of parameter to it.
Also, as a side note, if you know the $post and want the slug, it's just $post->post_name
Trying to remove the gallery shortcode from the post content and save in a variable for use elsewhere in the template. The new Wordpress gallery tool is great for selecting which images they want and assigning captions, hoping to use this to create the gallery, but then pull it out of the content on the front-end.
So this little snipped works just fine for removing the gallery and reapplying formatting... however I want to save that gallery shortcode.
$content = strip_shortcodes( get_the_content() );
$content = apply_filters('the_content', $content);
echo $content;
Hoping to save the shortcode so it can be parsed into an array and used to recreate a custom gallery setup on the front-end. An example of this shortcode I'm trying to save is...
[gallery ids="1079,1073,1074,1075,1078"]
Any suggestions would be greatly appreciated.
Function to grab First Gallery shortcode from post content:
// Return first gallery shortcode
function get_shortcode_gallery ( $post = 0 ) {
if ( $post = get_post($post) ) {
$post_gallery = get_post_gallery($post, false);
if ( ! empty($post_gallery) ) {
$shortcode = "[gallery";
foreach ( $post_gallery as $att => $val ) {
if ( $att !== 'src') {
if ( $att === 'size') $val = "full"; // Set custom attribute value
$shortcode .= " ". $att .'="'. $val .'"'; // Add attribute name and value ( attribute="value")
}
}
$shortcode .= "]";
return $shortcode;
}
}
}
// Example of how to use:
echo do_shortcode( get_shortcode_gallery() );
Function to delete First gallery shortcode from Post content:
// Deletes first gallery shortcode and returns content
function strip_shortcode_gallery( $content ) {
preg_match_all( '/'. get_shortcode_regex() .'/s', $content, $matches, PREG_SET_ORDER );
if ( ! empty( $matches ) ) {
foreach ( $matches as $shortcode ) {
if ( 'gallery' === $shortcode[2] ) {
$pos = strpos( $content, $shortcode[0] );
if ($pos !== false)
return substr_replace( $content, '', $pos, strlen($shortcode[0]) );
}
}
}
return $content;
}
// Example of how to use:
$content = strip_shortcode_gallery( get_the_content() ); // Delete first gallery shortcode from post content
$content = str_replace( ']]>', ']]>', apply_filters( 'the_content', $content ) ); // Apply filter to achieve the same output that the_content() returns
echo $content;
just use the get_shortcode_regex():
<?php
$pattern = get_shortcode_regex();
preg_match_all('/'.$pattern.'/s', $post->post_content, $shortcodes);
?>
that will return an array of all the shortcodes in your content, which you can then output wherever you feel, like so:
<?php
echo do_shortcode($shortcodes[0][1]);
?>
similarly, you could use the array entries to check for shortcodes in your content and remove them with str_replace():
<?php
$content = $post->post_content;
$content = str_replace($shortcodes[0][1],'',$content);
?>
Something like $gallery = do_shortcode('[gallery]'); might work.
