I want to create a simple Wordpress shortcode for recent posts to use it inside a post.
I know the basic steps of creating a shortcode:
1- I open the WP theme "functions.php" file and include a new custom file created in same directory i name it "custom-shortcode.php"
2- Inside the "custom-shortcode.php" i write the actual code:
<?php
// Shortcode function
function custom_shortcode() {
// Use WP recent posts function with default values return
return php wp_get_recent_posts( $args, $output );
}
// Add shortcode (WP function)
add_shortcode( 'recent-post', 'custom_shortcode' );
?>
I want to use the wp default function for getting recent posts, is my code will work?
I want to get shortcode with minimal code and with default values return so i can focus on learning how can i make my own shortcode.
Use
shortcode_atts(array( for make your custom style..
You can follow , http://codex.wordpress.org/Shortcode_API

I want to output a list of locations as a table and mark them up on a map. For this I have created a content type in WordPress with Pods with a property "Address". With a Pods shortcode, I am able to have the table created and list all the entries. With another Pods shortcode, I am able to generate a Leaflet shortcode.
The problem is that the Leaflet shortcode is output to the frontend, but is not interpreted by Leaflet as a map. If I use the Leaflet shortcode generated by Pods from the frontend in the backend, the map works as desired.
I'm afraid the problem arises because the shortcode generated by a shortcode is not taken into account and implemented.
I have created a WordPress page and noted the following shortcode:
[pods name="locations"]<br /><br />[/pods][pods name="locations"]<br />[leaflet-marker address="{#locations-address}"]<br />[/pods]
A correct shortcode is output in the frontend:
[leaflet-marker address="Ingolstädter Str. 101, 80939 München"]
In consultation with the developer of the Leaflet plugin for WordPress, I tried to insert the function with XYZ PHP code:
<?php
$a = do_shortcode( '[pods name="locations"][leaflet-marker]' . '[' . 'leaflet-marker address={#locations-address}' . ']' . '<br>[/pods]');
echo "[leaflet-map] $a [leaflet-marker]";
?>
The result is better, as the map is generated largely as desired, but when I insert the XYZ PHP code into the WordPress page, no map is output.
By default including a shortcode within a Pods shortcode will not work. If you need this functionality to work, you need to include the following constant in your wp_config.php file:
define('PODS_SHORTCODE_ALLOW_SUB_SHORTCODES',true);
Then, if you need to parse a shortcode within the Pods template, custom template or within your Pods shortcode, just add shortcodes=1 to the Pods shortcode.
Or you can use the filter below to have it always enabled:
add_filter( 'pods_shortcode', function( $tags ) {
$tags[ 'shortcodes' ] = true;
return $tags;
});
All these are explained at Pod's documentation.
I have found a solution in the meantime. The keyword is nested shortcodes (https://codex.wordpress.org/Shortcode_API) and the function "do_shortcode()".
Using a custom WordPress plug-in to run a script and output it as a custom shortcode, I was able to generate the map as desired. For this I used the following code. It is important to note that "do_shortcode()" must be used twice, first for Pods and then for Leaflet.
function map_func( $atts ){
$leaflet_map_shortcode = "[leaflet-map lat=48.13391418715657 lng=11.582841421510087 zoom=15 fitbounds max_zoom=19]";
$leaflet_map = do_shortcode($leaflet_map_shortcode);
$placese_marks_shortcode = '[pods name="places"]<br />[leaflet-marker address="{#places-address}" [...] [/leaflet-marker]<br />[/pods]';
$placese_marks = do_shortcode($placese_marks_shortcode);
$placese_marks2 = do_shortcode($placese_marks);
return $leaflet_map . $placese_marks2;
}
add_shortcode( 'map2', 'map_func' );
I am trying to create a shortcode from a page that currently resides in the back end. The page has several acf fields as part of a form that creates a request. I would now like to have the same page on the front end. I have tried following the syntax of creating a shortcode from a function after reading about shortocdes, its api and doc and several different tuts online.
add_shortcode('create_requests', array($this, 'load_custom_wp_admin_style'));
^ The attempt above didn't work and I don't get any output when I include the shortcode in a new page.
You can notice that the function I am trying to use 'load_custom_wp_admin_style' returns a null value and uses hooks.
This is the file that contains the function.
Try to include file like below code. I checked your file according to me you need use the plugin url it seems like you are developing the plugin
wp_register_style('your_namespace', plugins_url('style.css',__FILE__ ));
wp_enqueue_style('your_namespace');
wp_register_script( 'your_namespace', plugins_url('your_script.js',__FILE__ ));
wp_enqueue_script('your_namespace');
Assuming that the page you want to display on the front end is a normal WordPress page - created in the pages tab, post type page.
Very simply you can just use the following PHP code to include it in a template:
<?php
$page = get_post(192994);
echo $page->post_content;
?>
If it needs to be a shortcode you can add this into your functions.php:
function output_page_function($atts) {
$page_id = $atts['page_id'];
if (!$page_id) return false;
$page = get_post($page_id);
return $page->post_content;
}
add_shortcode('output_page', 'output_page_function');
And include a shortcode where desired (with 'page_id' attribute)
[output_page page_id=192994]
If it's not a WordPress page, but an actual wp-admin screen, then this would be significantly more difficult/not possible.
I want add Prettyphoto to my blog and I prepare filter:
add_filter( 'wp_get_attachment_link', 'sant_prettyadd');
function sant_prettyadd ($content) {
$content = preg_replace("/<a/","<a rel=\"prettyPhoto[slides]\"",$content,1);
return $content;
}
But where I should looking file function.php ?
When WordPress is integrated into Magento, the functions.php file is not used, which means that any code you add to it won't have any effect on the frontend of your blog.
The integration extension is Magento based and uses Magento templates to display your blog. You probably want to add the preg_replace function call to the post view template. This can be found at the following location:
app/design/frontend/base/default/template/wordpress/post/view.phtml
To make changes to this file, first copy it to your custom theme and edit it there. Look for the following line:
<?php echo $post->getPostContent() ?>
This is the code that retrieves the post content. You can use the preg_replace call here to achieve what you're trying to do.
I need to know how to take the output of a custom built Wordpress plugin and output it onto a specific page.
I know that I need to use the add_action() / add_filter() functions to call the function which outputs the plugins output when a wordpress hook function runs.
Currently I am using the 'the_content' hook.
This outputs my plugins output to all pages in my theme which call the the_content() function.
Which hook can I use to make the output only appear on a specific page.
Also
It would be useful to know how to create a page using my plugin.
Checkout is_page()
if (is_page(123)) {
// put your hooks here
}
put your code in a file inside plugin directory
then
use this
function page_directory()
{
if(is_page('123')){
$dir = plugin_dir_path( __FILE__ );
include($dir."custom/page.php");
die();
}
}
add_action( 'wp', 'page_directory' );
I am using wordpress wp-admin to create the menu. It is under Appearance/menu.
I have a link that points to /members/ but what I really need is a link to /members/$logged_user...
For example /members/user_1 or /members/user_2.
How can I do that?
I dont know if it is important, but I am using buddypress plugin.
I have written a short script for adding dynamic buddypress links in wordpress menu. Hope it helps
I have added custom links in wordpress menu replacing username in link with --username--
example
http://website_name.com/members/--username--/messages/
then add this code in function.php
add_filter( 'nav_menu_link_attributes', 'menu_override', 10, 3 );
function menu_override( $atts, $item, $args ) {
$user = wp_get_current_user();
$newlink = str_replace("--username--", $user->user_login, $atts[href]);
$atts[href] = $newlink;
return $atts;
}
The default menu doesn't really have that option. But you can make your own walker function, searching for the keyword and replacing it with the current user.
See http://codex.wordpress.org/Function_Reference/wp_nav_menu#Using_a_Custom_Walker_Function
But it would probably be faster and more manageable to just place the link outside the menu call with some static html and the needed php.
You can use the BuddyPress Custom Profile Menu plugin to get close to this functionality, otherwise you will have to write custom code that uses actions/filters of wp_nav_menu().
