Basically, I'm trying to add the tag <!--nextpage--> to generate the pagination of the post dynamically using some shortcode in a plugin,
I've tried to use the following code to do such functionality.
public function __construct() {
add_shortcode('CONTINUED', array(&$this, 'continued_handle'));
}
public function continued_handle() {
global $post;
add_filter('the_content', array(&$this, 'your_post_split'));
return $this->your_post_split($post);
}
public function your_post_split($content) {
$output = '<div>In page 1</div>';
$output .= '<!--nextpage-->';
$output .= '<div>In page 2</div>';
return $output;
}
When I use the shortcode [CONTINUED] on a page, I want it to echo <div>In page 1</div> then process the <!--nextpage--> like it normally would in WordPress and start the pagination.
What it's actually doing is returning this in the post
<div>In page 1</div><!--nextpage--><div>In page 2</div>
It's not actually doing the functionality of <!--nextpage--> in which I want it to

I've a WordPress website and am trying to add a custom search option in the website's home page as well in the header section. Unfortunately I can't see any option to include it from the website's dashboard and decided to follow the link to create a custom one as follows:
Tutorial Link - Custom Search
and this is the code that I've tried same as the tutorial:
add_action('tickercontainer','add_search_to_footer'); //Guessinghere I've to declare the div class
function add_search_to_footer() {
get_search_form();
}
function SearchFilter($query) {
if ( !is_admin() && $query->is_search ) {
$query->set('post_type', 'post'); //OR USE 'PRODUCT'
}
return $query;
}
add_filter('pre_get_posts','SearchFilter');
function storefront_search_form_modify( $html ) {
return str_replace( array('Search …','Search'), array('WooCommerce Hooks, Storefront Theme, Google AdWords...','Search Article'), $html );
}
add_filter( 'get_search_form', 'storefront_search_form_modify' );
function new_nav_menu_items($items) {
$searchicon = '<li class="search"><i class="fa fa-search" aria-hidden="true"></i></li>';
$items = $items . $searchicon;
return $items;
}
add_filter( 'wp_nav_menu_additional-resources_items', 'new_nav_menu_items' );
Though I am not sure what I am missing here and would expect some ideas to implement in an appropriate way.
Note: Right now, after including the code above, I can't see the search option in the website.
I have this PHP script:
function myshortcode_title( ){
return get_the_title();
}
add_shortcode( 'page_title', 'myshortcode_title' );
What is the shortcut i need for the page title to be shown? What do i need to put in the HTML for the fetched title to be shown
Add this to your theme, or make an plugin from it.
/* title to get the post title */
function getPageTitle() {
global $wp_query;
return get_post_title($wp_query->post->ID);
}
/* Add shortcode */
add_shortcode('page_title', 'getPageTitle');
for more ShortCode Api
You may use this.
echo do_shortcode('[page_title]');
https://developer.wordpress.org/reference/functions/do_shortcode/
I've created a theme from scratch and I have issues creating shortcodes. I have the following code:
functions.php
function caption_shortcode( $atts, $content = null ) {
return '<span class="caption">' . $content . '</span>';
}
add_shortcode( 'caption', 'caption_shortcode' );
in the WP Admin page editor:
[caption]My Caption[/caption]
on the page template page:
echo do_shortcode('[caption]');
The shortcode seems to be somehow working as it returns the HTML but not the $content.
My problem is that I can't seem to get my hand on the $content and display it using the shortcode. Any idea why this is happening?
P.S. I don't want to use the_content() function to display all the content, I want to use the shortcodes to divide the content the user adds in several pop-ups and child sections of the page.
Thanks!
Make sure you user shotcode same page
// [baztag]content[/baztag]
function baztag_func( $atts, $content = '' ) {
return $content;
}
add_shortcode( 'baztag', 'baztag_func' );
echo do_shortcode('[baztag]');
I'd like to show some custom content after the_content. However, I can't make it work. the custom content always shows before the_content. Here's my code:
function after_content($content){
function custom_content() {
include('page.php');
...
}
$content = $content . custom_content();
return $content;
}
add_filter('the_content', 'after_content');
I have successfully added a content after short description on single product page with
if (!function_exists('my_content')) {
function my_content( $content ) {
$content .= '<div class="custom_content">Custom content!</div>';
return $content;
}
}
add_filter('woocommerce_short_description', 'my_content', 10, 2);
I saw that in short-description.php there was apply_filters( 'woocommerce_short_description', $post->post_excerpt )
so I hooked to that.
In the same way, I'd like to add a content after the add to cart button, so I found do_action( 'woocommerce_before_add_to_cart_button' ), and now I am hooking to woocommerce_before_add_to_cart_button. I'm using
if (!function_exists('my_content_second')) {
function my_content_second( $content ) {
$content .= '<div class="second_content">Other content here!</div>';
return $content;
}
}
add_action('woocommerce_after_add_to_cart_button', 'my_content_second');
But nothing happens. Can I only hook to hooks inside apply_filters? From what I've understood so far by working with hooks is that you only need a hook name to hook to and that's it. The first one was a filter hook, so I used add_filter, and the second one is action hook so I should use add_action, and all should work. So why doesn't it?
Here, you need to echo content as it is add_action hook.
add_action( 'woocommerce_after_add_to_cart_button', 'add_content_after_addtocart_button_func' );
/*
* Content below "Add to cart" Button.
*/
function add_content_after_addtocart_button_func() {
// Echo content.
echo '<div class="second_content">Other content here!</div>';
}
You need to do echo instead of return.
add_action( 'woocommerce_after_add_to_cart_button', 'ybc_after_add_to_cart_btn' );
function ybc_after_add_to_cart_btn(){
//add text OR HTML here
echo '<p>After custom text here</p>';
}
If you want the same thing on the shop archive page then you need to use the woocommerce_loop_add_to_cart_link filter to modify the add to cart button.
When using 'Action Hook' adding the content(html) out of php would be easy.
if (!function_exists('my_content_second')) {
function my_content_second( $content ) {
?>
<div class="second_content">Other content here!</div>;
<?php
}
}
add_action('woocommerce_after_add_to_cart_button', 'my_content_second');
If need to add dynamic content just echo that content using variables or add using some condition.
Filter hooks are useful to modify the existing content and needs a return statement (the modified)
Action hooks are mostly useful to add content.
