I include the comments on the page afterwards with ajax, required code is in the plugin, but comment_template() function does not work when the request goes plugin file, Ajax request is successful, but there are no comments.
Codes that go to Ajax are as follows.
add_action('wp_ajax_nopriv_comment_update_get','comment_update_get');
add_action('wp_ajax_comment_update_get', 'comment_update_get');
function comment_update_get(){
global $withcomments;
$withcomments = 1;
$post = get_post($_POST['post_id']);
comments_template();
die();
}
From the Code Reference:
Will not display the comments template if not on single post or page,
or if the post does not have comments.
If you take a look at the source code, you'll notice that the comments_template() function checks whether we're currently on a post or a page, or if the global $post object is set up.
So:
function comment_update_get(){
// Set up our required global objects
global $post, $withcomments;
$withcomments = 1;
$post = get_post( $_POST['post_id'] );
// Load the comments template
comments_template();
// We're done here
wp_die();
}
add_action( 'wp_ajax_nopriv_comment_update_get','comment_update_get' );
add_action( 'wp_ajax_comment_update_get', 'comment_update_get' );

I'm trying to disable Jetpack Carousel on a specific post ID using the following code in my functions.php
function djcoh_disable_carousel( $value ) {
wp_reset_query();
if ( is_page( 614 ) ) {
$value = true; // true to disable Carousel
}
// Return original or changed value
return $value;
}
add_filter( 'jp_carousel_maybe_disable', 'djcoh_disable_carousel' );
Here's the reference for jp_carousel_maybe_disable on GitHub
It seems that I'm unable to use is_page() within functions.php - though I thought I'd be able to by using wp_reset_query() as mentioned in the codex
What am I missing?!
The code you have is from a tutorial which is intended for running as a simple plugin. The reason your code doesn't currently work is because you are using it in the functions.php.
In it's current form your function is called as soon as it is read as part of the functions.php file. This is usually some time before the page is formed, and so you can't grab the page id with is_page{}.
Instead you should query the page and get it's id as follows:
function djcoh_disable_carousel( $value ) {
//get the global
global $post
echo "TEST PAGE ID: ".$post->ID;
//wp_reset_query();
if ( $post->ID == 614 ) {
$value = true; // true to disable Carousel
}
wp_reset_query();
// Return original or changed value
return $value;
}
add_filter( 'jp_carousel_maybe_disable', 'djcoh_disable_carousel' );
if that doesn't work try this:
function djcoh_disable_carousel( $value ) {
//get the global
global $wp_query;
$post_ID = $wp_query->post->ID;
echo "TEST PAGE ID: ". $post_ID;
//wp_reset_query();
if ( $post_ID == 614 ) {
$value = true; // true to disable Carousel
}
wp_reset_query();
// Return original or changed value
return $value;
}
add_filter( 'jp_carousel_maybe_disable', 'djcoh_disable_carousel' );
If none of the above work then your script is being called far too early in the process to grab the page id. So, the easiest option would be to simply place this script in it's own .php file and then upload that to the plugins root folder. Then activate it from the plugins menu.
The final option would be to create this as a filter or script and add the function call in the actual page template.
I managed this by using REQUEST_URI within a plugin file:
<?php
// No direct access
if ( ! defined( 'ABSPATH' ) ) exit;
if ( $_SERVER["REQUEST_URI"] === '/PAGE-SLUG/' ) {
add_filter( 'jp_carousel_maybe_disable', '__return_true' );
}
Change PAGE-SLUG for your slug and you are all set.
You can find info on REQUEST_URI in PHP's manuals:
'REQUEST_URI'
The URI which was given in order to access this page; for instance, '/index.html'.
It seems simplest to conditionally dequeue the Jetpack carousel script and stylesheet. The conditionals that you would typically use to control output would be available at the point in the request when the wp_footer action fires.
add_action( 'wp_footer', function() {
if ( is_page( $page ) ) {
wp_dequeue_script( 'jetpack-carousel' );
wp_dequeue_style( 'jetpack-carousel' );
}
}
Be certain to modify the is_page function to include the $page parameter or the condition will match all pages. Place the code in your theme's functions.php file and the Jetpack carousel should be disabled.
I'm creating a plugin OOP for wordpress. The plugin creates a new custom post type called teams. Within a team page a could use the shortcode [program] to generate some predefault html code. Also i've created custom fields with new meta boxes.
The problem however is: when i'm entering the page thats calling the plugin, equal the team page with the sortcode i need to get post id within my plugin to retrieve get_post_meta().
I've tried the following things:
public function __construct(){
// not working
$post;
$post->ID;
// not working
global $wp_query;
$post_id = $wp_query->post->ID;
$post = get_post( $post_id );
// not workiing
echo '<pre>';
print_r('post_id:' . get_the_ID());
echo '</pre>';
}
How could i receive the custom post id within my plugin when i visited the page from frontend (so the plugin is called, runs the shortcode)
My main class gets loaded like this:
function run_plugin() {
$plugin = new MyPlugin();
$plugin->run();
}
run_plugin();
Within MyPlugin the constructor looks like
public function __construct() {
if ( defined( 'PLUGIN_NAME_VERSION' ) ) {
$this->version = PLUGIN_NAME_VERSION;
} else {
$this->version = '1.0.0';
}
$this->plugin_name = 'MyPlugin';
if(!empty(get_option($this->plugin_name))){
$this->clientID = get_option($this->plugin_name)['client_id'];
}
$this->load_dependencies();
$this->set_locale();
$this->define_admin_hooks();
$this->define_public_hooks();
$this->define_shortcodes();
}
If your plugin constructor is getting called too early, the post data won't be set up and ready to use.
You'll need to hook into one of WPs actions that run after everything is ready. The init action should be enough for the post data, but depending on what else you need you can hook into wp_loaded, as it doesn't run until after WordPress is fully loaded.
function run_plugin() {
$plugin = new MyPlugin();
$plugin->run();
}
/* run_plugin(); */ // <- instead of this....
add_action( 'wp_loaded','run_plugin' ); // <- ...do this
Try to define post as global like
global $post
I trying to make a shortcode to output specific page excerpt.Did research but there is no output on the code that I structured.
function page_shortcode( $atts )
{
$page_id = 173;
$page_data = get_page( $page_id );
$the_excerpt = $page_data->post_excerpt;
echo $the_excerpt;
}
add_shortcode( 'page_shortcode_excerpt', 'page_shortcode');
The page excerpt activation code is okay! but the get_page function you used in your shortcode is deprecated. you can check here enter link description here for more information.
Try putting below code for your shortcode:
function page_shortcode( $atts )
{
$page_id = 173;
$page_data = get_post( $page_id );
$the_excerpt = $page_data->post_excerpt;
return $the_excerpt;
}
add_shortcode( 'page_shortcode_excerpt', 'page_shortcode');
Also when you edit the page with id=173 from your admin panel, from screen options check excerpt check box at the top of the page and check if the excerpt field has any value or not. If not excerpt on front end won't show anything.
Hope this will help you!
I just needed to activate excerpt on page using this line of code
add_action( 'init', 'add_excerpts_to_pages' );
function add_excerpts_to_pages() {
add_post_type_support( 'page', 'excerpt' );
}

If I take Wordpresses AJAX/PHP example how would I call $whatever in another function? If I do get a result outside of the initial function (below) it is always 0.
add_action( 'wp_ajax_my_action', 'my_action_callback' );
function my_action_callback() {
global $wpdb; // this is how you get access to the database
$whatever = intval( $_POST['whatever'] );
$whatever += 10;
echo $whatever; //
die();
}

I suspect it is very simple but when you get in a certain mindset you cannot look beyond the blinders.
I'm new to Wordpress & PHP, so kindly excuse the naivety of the question, if any.
I'm building a plugin where I need to select values from the database and create a new HTML page with the values. I'm using a custom template file.
What I've done till now
Extracted the values from database
Load & display my own template in my plugin file
add_action( 'init', 'leb_add_endpoint' );
function leb_add_endpoint()
{
add_rewrite_endpoint( 'result', EP_PERMALINK );
}
add_action( 'template_include', 'leb_render_template' );
function leb_render_template($default_template) {
//some code removed for brevity
if ( ! is_singular() || !isset($wp_query->query_vars['result']) )
{
return $default_template;
}
$sample_result = $wpdb->get_var($wpdb->prepare($sql));
$default_template = plugin_dir_path(__FILE__) . '/my-custom-template.php';
return $default_template;
}
The content of my-custom-template.php is as follows
<?php
/* Template Name: My Template*/
echo '<h1>Testing</h1>';
?>
The page gets displayed without any problem. All I want is to insert $sample_result and other similar results pulled form database into my-custom-template.php
I need to generate dynamic pages based on values pulled from DB. So each time, the final page created might be different. E.g. if one hits www.example.com/sample-post/result, a page will be shown with values pulled from the DB. If one hits www.example.com/another-sample-post/result, a different page will be shown with different values. Both these pages will have the same design, only a few values will be different. This is what I'm trying to achieve.
How can I do that? Please help me. I'm stuck. :(
You need to define "result" in query vars.
Use EP_ROOT Endpoint Mask ( result/{var} is located in the root )
Inside template_include hook, you can find result value inside $wp_query object.
I've already tested the code
// Add a new var to query vars
function result_add_query_vars( $vars ){
$vars[] = 'result';
return $vars;
}
add_filter( 'query_vars', 'result_add_query_vars' );
// Add endpoint
function result_add_endpoint() {
add_rewrite_endpoint( 'result', EP_ROOT );
}
add_action( 'init', 'result_add_endpoint');
// change the template
function result_render_template($template)
{
global $wp_query;
if ( array_key_exists( 'result', $wp_query->query_vars ) ) {
$result = get_query_var('result');
$new_template = plugin_dir_path(__FILE__) . '/my-custom-template.php';
return $new_template;
} else {
return $template;
}
}
add_action( 'template_include', 'result_render_template' );
Now you can retrieve the query var in your custom template
/*
* Template Name: My Custom Template
*/
$result = get_query_var('result');
echo $result;
Well why don't you use $wp_query Inside your my-custom-template.php
<?php
/* Template Name: My Template*/
global $wp_query;
echo '<pre>';
print_r($wp_query); // Use this in case you want to see what else do you have with you.
echo '<pre/>';
// Now you can use $wp_query to build your dynamic query at run time.
// This will allow you to perform task at run time
?>
To Retrieve Meta
If you have saved something as a meta then
<?php
$meta_values = get_post_meta( $post_id, $key, $single );
?>
To Retrieve Child Post
If you want to retrieve child posts then
<?php
if ( have_posts() ) :
// Start the Loop.
while ( have_posts() ) : the_post();
// Do your stuff here such as below
the_title();
the_content();
endwhile;
else:
echo 'No Post Found';
endif;
?>
1) Write this function in function.php in your active template.
function leb_render_template() {
//some code removed for brevity
//$sql = 'YOUR_QUERY_CODE'
$sample_result = $wpdb->get_var($wpdb->prepare($sql));
return $my_template;
}
add_action('wp_ajax_leb_render_template', 'leb_render_template');
add_action('wp_ajax_nopriv_leb_render_template', 'leb_render_template');
2) Call function in your custom template.
<?php
/* Template Name: My Template*/
echo '<h1>Testing</h1>';
$result = leb_render_template();
print_r($result); // Print Your function output.
?>
