Creating a Query Post Shortcode for WordPress

Daniel — Fri, 24 Jun 2022 18:25:53 +0000

With this tutorial, we will create a shortcode that will return the results of a WordPress query.

We will be creating a add_shortcode shortcode that will contain the shortcode name and function as parameters.
With this example, we will call a query for a Video post type sorted by number of likes.

We edited the get option inside the shortcode if you have options. Then we run the new WP_Query.

 'viavideos',
		'meta_key'             => '_post_like_count',
		'orderby'              => 'meta_value_num',
        'order'                => 'DESC',
		'posts_per_page'       => -1,
		) );
	if ( $query->have_posts() ) { 
	?>
	
	
	have_posts() ) : $query->the_post(); ?>

Calcul Pourcentage Post Meta Key – Post Type :
This tutorial will allow you to calculate the total percentage (Num) of a Meta post of Post type’s 100%.

In our example, we using a viavideos post type. We have various meta posts that will allow us to fetch the video’s language.

We want to display the video’s percentage in a language according to the total number of videos.

We also have a calc function in our files and display example for a language meta post. This tutorial is well documented and explains what it displays.

Note: The progress bar is displayed via a CSS bootstrap. Simply add the CSS line in your header or user your own progress bar.

WordPress Search Function

Daniel — Sun, 06 Feb 2022 20:38:51 +0000

Sometimes, it is possible that you experience query issues occur especially with Custom Post Type. Here’s a solution to address this issue.
Here’s a function that do an advanced search to optimize your users’ searches on your website. First of all, make sure that the searchform.php is triggered properly.

Afterwards you need to add a function filter to your functions.php file.

///////////////////////////////////////
// Requete de recherche mots clés tous post
///////////////////////////////////////
function searchfilter($query) {
 
if ($query->is_search && !is_admin() ) {
$query->set('post_type',array('post','recettes'));
}
 
return $query;
}
add_filter('pre_get_posts','searchfilter');

You’ll notice that with this filter, we do a query on general posts but also a Custom Post Type. Simply replace the Custom Post Type by yours.

Let’s image that we have a second Custom Post Type called portfolio, so how can we add it after the first one?

///////////////////////////////////////
// Requete de recherche mots clés tous post
///////////////////////////////////////
function searchfilter($query) {
 
if ($query->is_search && !is_admin() ) {
$query->set('post_type',array('post','recettes','portfolio'));
}
 
return $query;
}
add_filter('pre_get_posts','searchfilter');

Your search.php will display the results.

Creating a Shortcode to Obtain a Post’s ID

Daniel — Wed, 11 Jul 2018 13:18:08 +0000

With this tutorial, we will create a shortcode that will allow us to fetch the ID of the current post. This shortcode is often referred to as current post id . For example, this can be used to fetch a param and get the value in order to stash it in a form.

We will need to add this shortcode into our functions.php file and will return the current post id.

//[thepostid]
function thepostidfunc( $atts ){
         global $post;
         return $post->ID;   
}
add_shortcode( 'thepostid', 'thepostidfunc' );

Puis vous pouvez l’appeler de cette façon :

Randomly Display Taxonomy Terms

Daniel — Tue, 01 May 2018 13:32:27 +0000

With this tutorial, we’re going to show you how to display randomly display taxonomies. For example, we’ll create a Post Type called Event whose taxonomy will be Event Type. We consult an Event page and under its results, we want to randomly display additional taxonomy except for the one we’re currently viewing.

They are like similar terms, but random.

For our example:
Post Type: Events
Taxonomy: Event type (must be the same as the category name)
Template used: taxonomy-type-evenements.php

Thus we will create a query that will allow us to do so. We will use the get_terms function and add our args. Afterwards, we will get a random result and we will indicate how many results to return. To display the results, we close the loop with a foreach for every term.

We also must not forget to exclude the term we are currently consulting with the get_queried_object_id(); that we use with our variable before the get_terms.

Randomly Display Taxonomy Terms

 'type-evenements',
	'hide_empty'    => false,
	'exclude'       => array($currentid)
	) );
	// Randomize Term Array
	shuffle( $terms );
	// Grab Indices 0 - 5, 6 in total
	$randterms = array_slice( $terms, 0, 2 );
?>

So by using get_terms, make sure to change the args for yours without adding any new ones.

WordPress: Template page Post Type & Redirect or Create An Page Archive Post Type

Daniel — Thu, 05 Apr 2018 22:27:40 +0000

With this tutorial, we will create a redirect that forces a Post Type template to use a WordPress page by using template_redirect.

The first step is to create your Post Type page template. For example, if you’re using the term team, you’ll need a template-equipe.php page template.

In your function, you’ll only need one condition: that it needs a page called Your Team that uses the page template created above. Your page needs to have the your-team slug i.e. the full URL should be https://www.domain-name.com/your-team.

What’s interesting with using Post Type template pages is that you can set it apart from the index and archive.php files allowing you to customize it by fetching results from a custom loop query.

Votre page template Post Type (Un exemple) :

Create a wp_redirect for an archive template page:

Alternatively, if you do not want to create a template page and a redirect, simply create an archvie page named with your Post Type such as Team which would translate to archive-equipe.php.

In this case, a redirect is not necessary as WordPress will automatically use the archive-equipe.php template.

You can use the same condition for other customed archives. If you do not use a Post Type template, WordPress will use the archive.php and its loop.

How to Duplicate Articles Without Plugins

Daniel — Wed, 28 Feb 2018 19:07:19 +0000

With this tutorial, we will use a function that will allow you to duplicate a WordPress post without using a plugin. Admins can easily duplicate a draft to save time.

It is important to understand that while duplicating is a time-saver, we have to be careful with the next post. We need to double-check the URL’s slug in the duplicated post because it will have the same URL with a -2 appended to it meaning you’ll need to tailor it based on the newest post.

In our function if we do an isset get post, we’ll first validate if the user has admin rights. And then we fetch the previous post’s attributes and afterwards we use wp_insert_post in order to recuperate taxonomy and category information. Finally, we validate and fetch all of the posts’ meta and add them into an SQL query.

function themepress_duplicate_post_as_draft(){
	global $wpdb;
	if (! ( isset( $_GET['post']) || isset( $_POST['post'])  || ( isset($_REQUEST['action']) && 'themepress_duplicate_post_as_draft' == $_REQUEST['action'] ) ) ) {
	wp_die('No post to duplicate has been supplied!');
	}
 
	/*
	 * get the original post id
	 */
	$post_id = (isset($_GET['post']) ? $_GET['post'] : $_POST['post']);
	/*
	 * and all the original post data then
	 */
	$post = get_post( $post_id );
 
	/*
	 * if you don't want current user to be the new post author,
	 * then change next couple of lines to this: $new_post_author = $post->post_author;
	 */
	$current_user = wp_get_current_user();
	$new_post_author = $current_user->ID;
 
	/*
	 * if post data exists, create the post duplicate
	 */
	 if (isset( $post ) && $post != null) {
 
		/*
		 * new post data array
		 */
		$args = array(
			'comment_status' => $post->comment_status,
			'ping_status'    => $post->ping_status,
			'post_author'    => $new_post_author,
			'post_content'   => $post->post_content,
			'post_excerpt'   => $post->post_excerpt,
			'post_name'      => $post->post_name,
			'post_parent'    => $post->post_parent,
			'post_passwothemepress'  => $post->post_passwothemepress,
			'post_status'    => 'draft',
			'post_title'     => $post->post_title,
			'post_type'      => $post->post_type,
			'to_ping'        => $post->to_ping,
			'menu_othemepresser'     => $post->menu_othemepresser
		);
 
		/*
		 * insert the post by wp_insert_post() function
		 */
		$new_post_id = wp_insert_post( $args );
 
		/*
		 * get all current post terms ad set them to the new post draft
		 */
		$taxonomies = get_object_taxonomies($post->post_type); // returns array of taxonomy names for post type, ex array("category", "post_tag");
		foreach ($taxonomies as $taxonomy) {
			$post_terms = wp_get_object_terms($post_id, $taxonomy, array('fields' => 'slugs'));
			wp_set_object_terms($new_post_id, $post_terms, $taxonomy, false);
		}
 
		/*
		 * duplicate all post meta just in two SQL queries
		 */
		$post_meta_infos = $wpdb->get_results("SELECT meta_key, meta_value FROM $wpdb->postmeta WHERE post_id=$post_id");
		if (count($post_meta_infos)!=0) {
			$sql_query = "INSERT INTO $wpdb->postmeta (post_id, meta_key, meta_value) ";
			foreach ($post_meta_infos as $meta_info) {
				$meta_key = $meta_info->meta_key;
				$meta_value = addslashes($meta_info->meta_value);
				$sql_query_sel[]= "SELECT $new_post_id, '$meta_key', '$meta_value'";
			}
			$sql_query.= implode(" UNION ALL ", $sql_query_sel);
			$wpdb->query($sql_query);
		}
		/*
		 * finally, redirect to the edit post screen for the new draft
		 */
		wp_redirect( admin_url( 'post.php?action=edit&post=' . $new_post_id ) );
		exit;
	} else {
		wp_die('Post creation failed, could not find original post: ' . $post_id);
	}
}
add_action( 'admin_action_themepress_duplicate_post_as_draft', 'themepress_duplicate_post_as_draft' );
 
/*
 * Add the duplicate link to action list for post_row_actions
 */
function themepress_duplicate_post_link( $actions, $post ) {
	if (current_user_can('edit_posts')) {
		$actions['duplicate'] = 'Duplicate';
	}
	return $actions;
}
 
add_filter( 'post_row_actions', 'themepress_duplicate_post_link', 10, 2 );
add_filter( 'page_row_actions', 'themepress_duplicate_post_link', 10, 2 );

We noticed that once the requirements have been filled, we enable the filter where we need it. In this case, we have two filters: post_row_actions and page_row_actions. One for the post and the other for the pages meaning that duplication will be enabled for both types.
If you want to do it for another post type such as Portfolio or testimonial, you’ll a filter similar to this: add_filter( ‘nomdutypedepost_row_actions’, ‘themepress_duplicate_post_link’, 10, 2 ); after the two other filters.

Display a Specific Link if User Has Post Published

Daniel — Thu, 19 Oct 2017 13:22:21 +0000

With this tutorial, we will show you how to display a specific menu item if a user has a Post Type published.

First we need to create a function that will allows us to create a query that will return the number of Post Type published by the user. In this example below, you need to replace the Post Type by yours or the posts. We need to return this query that the result is different than 0.

function themespress_user_has_posts($user_id) {
  $result = new WP_Query(array(
    'author'           => $user_id,
    'post_type'        => 'any',
    'post_status'      => 'publish',
    'posts_per_page'   => 1,
  ));
  return (count($result->posts)!=0);
}

Display the Number of Images Attached to Post IDs

Daniel — Sun, 06 Aug 2017 18:02:41 +0000

In this tutorial, we will create a few lines of code that will allow you to display the number of images attached to a Post ID with the help of a WordPress query.

First, in our query, we will need the $attachments variable which contains get_children of all images linked to Post or Post Type. And then we create a new $count variable that will count the images.

With a foreach, we will display Post ID’s number of images as long as the query will find Post Ids.

Here’s the code to use with your Post or Post Type query.

global $post;
$attachments = get_children ( 
   array( 
   'post_parent'      => $post->post_parent, 
   'post_status'      => 'inherit', 
   'post_type'        => 'attachment', 
   'post_mime_type'   => 'image', 
   'order'            => 'ASC', 
   'orderby'          => 'menu_order ID' ) 
);
 
$count = count( $attachments );
$specific = array();
$i = 1;
 
foreach ( $attachments as $attachment ) {
    $specific[$attachment->ID] = $i;
    ++$i;
}

We display the results of the loop the number of images attached to the selected Post ID:

echo $count;

Creating a Custom Post Type

Daniel — Sat, 05 Aug 2017 17:35:15 +0000

Using a Custom Post Type is a great way to separate your custom content from your post given that WordPress posts are for blogging and non necessarily custom content.

So for example, let’s say you want to create a new section on your website, different from the blog, titled Tutorials. In order to display them accordingly, you’ll need to create a custom Post Type.

Here’s how you can create your own Custom Post Type:

// Register Custom Post Type
function theme_custom_post_type() {
 
	$labels = array(
		'name'                  => _x( 'Post Types', 'Post Type General Name', 'text_domain' ),
		'singular_name'         => _x( 'Post Type', 'Post Type Singular Name', 'text_domain' ),
		'menu_name'             => __( 'Post Types', 'text_domain' ),
		'name_admin_bar'        => __( 'Post Type', 'text_domain' ),
		'archives'              => __( 'Item Archives', 'text_domain' ),
		'attributes'            => __( 'Item Attributes', 'text_domain' ),
		'parent_item_colon'     => __( 'Parent Item:', 'text_domain' ),
		'all_items'             => __( 'All Items', 'text_domain' ),
		'add_new_item'          => __( 'Add New Item', 'text_domain' ),
		'add_new'               => __( 'Add New', 'text_domain' ),
		'new_item'              => __( 'New Item', 'text_domain' ),
		'edit_item'             => __( 'Edit Item', 'text_domain' ),
		'update_item'           => __( 'Update Item', 'text_domain' ),
		'view_item'             => __( 'View Item', 'text_domain' ),
		'view_items'            => __( 'View Items', 'text_domain' ),
		'search_items'          => __( 'Search Item', 'text_domain' ),
		'not_found'             => __( 'Not found', 'text_domain' ),
		'not_found_in_trash'    => __( 'Not found in Trash', 'text_domain' ),
		'featured_image'        => __( 'Featured Image', 'text_domain' ),
		'set_featured_image'    => __( 'Set featured image', 'text_domain' ),
		'remove_featured_image' => __( 'Remove featured image', 'text_domain' ),
		'use_featured_image'    => __( 'Use as featured image', 'text_domain' ),
		'insert_into_item'      => __( 'Insert into item', 'text_domain' ),
		'uploaded_to_this_item' => __( 'Uploaded to this item', 'text_domain' ),
		'items_list'            => __( 'Items list', 'text_domain' ),
		'items_list_navigation' => __( 'Items list navigation', 'text_domain' ),
		'filter_items_list'     => __( 'Filter items list', 'text_domain' ),
	);
	$args = array(
		'label'                 => __( 'Post Type', 'text_domain' ),
		'description'           => __( 'Post Type Description', 'text_domain' ),
		'labels'                => $labels,
		'supports'              => array( 'title', 'editor', 'excerpt', 'thumbnail', 'post-formats', ),
		'taxonomies'            => array( 'category', 'post_tag' ),
		'hierarchical'          => false,
		'public'                => true,
		'show_ui'               => true,
		'show_in_menu'          => true,
		'menu_position'         => 5,
		'show_in_admin_bar'     => true,
		'show_in_nav_menus'     => true,
		'can_export'            => true,
		'has_archive'           => true,		
		'exclude_from_search'   => false,
		'publicly_queryable'    => true,
		'capability_type'       => 'page',
	);
	register_post_type( 'POSTTYPENAME', $args );
 
}
add_action( 'init', 'theme_custom_post_type', 0 );
