execute do_shortcode in functions.php - wordpress

I'm trying to run a do_shortcode in functions.php with no luck
I'm using Types plugin http://wp-types.com/ for creating custom post types and custom fields.
What I'm trying do is adding a custom column in admin for view all custom posts that displays a thumbnail from a custom field.
This is what I got so far, but it seems that the shortcode doesn't work inside functions.php
// add a column for custom post type (products)
add_filter('manage_product_posts_columns', 'add_thumbnail_column');
add_action('manage_product_posts_custom_column', 'add_thumbnail_content', 10, 2);
function add_thumbnail_column($defaults)
{
$newSlice = array('thumbnail' => 'Image preview');
$counter = 2;
$array_head = array_slice($defaults,0,$counter);
$array_tail = array_slice($defaults,$counter);
$defaults = array_merge($array_head, $newSlice);
$defaults = array_merge($defaults, $array_tail);
return $defaults;
}
function add_thumbnail_content($column_name, $post_ID)
{
// this one works when putting into post content
echo do_shortcode('[types field="square-picture" id="' . $post_ID . '" size="thumbnail"]' . '[/types]');
}
Can anyone help please?

In the Wordpress notes for the function it says
"If there are no shortcode tags defined, then the content will be
returned without any filtering. This might cause issues if a plugin is
disabled as its shortcode will still show up in the post or content."
Types may be conditionally declaring their short code only when you are on the frontend. What may be happening is that, in the admin, the short code is not defined and you are simply getting a false return. While on the frontend, the shortcode is defined and you get the results you intended.

Custom Columns Don't Display Anything

I have added a new column to a custom post type to display the post's ID. This works for the WordPress core post type, but not for my custom post type. I have tried using the manage_{post_type}_custom_column hook and just applying it to all posts, but neither works.
It DOES add the custom column headers, but I can't populate them with anything at all when viewing the custom post type.
This is what it looks like when viewing the custom post type
and
this is what it looks like when viewing a regular core post.
// Add post ID column to use an order ID in all posts view.
add_filter('manage_posts_columns', 'oms_order_id_header');
add_action('manage_posts_custom_column', 'oms_order_id_column', 10, 2);
function oms_order_id_header($columns) {
//Remove title column
//unset($columns['title']);
//Add new columns
$columns['order_id_header'] = 'Order ID';
$columns['customer_header'] = 'Customer';
$columns['author'] = 'Owner';
return $columns;
}
function oms_order_id_column( $column, $post_id ) {
if ($column == 'order_id_header') {
echo $post_id;
}
}
This turned out to be an issue with the post type being set to hierarchical. Hierarchical post types need to be targeted by a different action hook than the one used here.
Instead of manage_posts_custom_column, hierarchical post types need to use manage_pages_custom_column.
I just tried you code and it seems to be working perfect on my WordPress installation in both cases: Custom Post and Post.
Maybe your error is happening because your posts are drafts? I don't think so but maybe. (I tried your code also with drafts on my installation and it worked). Here is the screenshot:
Try printing "hello world" instead of the $post_id to check if it prints in all cases.

Visual Composer Grid with do_action shortcode is not working

I have visual composer which is packed with total theme. When I put the following grid short code in my page in the editor it works correctly.
[vc_basic_grid post_type="post_type" max_items="10" item="masonryGrid_SlideFromLeft" grid_id="vc_gid:1458178666639-80ebf3775500c87d35de078c3422fe96-10" taxonomies="555"]
However, when I call the exact same code using do_action it gives the following javascript error. I checked the html output and it is the same using do_action like putting the short code in editor.
Error: Syntax error, unrecognized expression: {'status':'Nothing found'}

Any help is greatly appreciated.
Well, you can't output contents directly in your templates by using core shortcodes of VC like that.
1. Problem:
For security, besides nonce, VC uses page_id and shortcode_id to check AJAX request/respond data.
The shortcode_id is automatically generated by VC, you can not harcode it.
For example, this is the shortcode you see on admin editor screen:
[vc_basic_grid post_type="post_type" max_items="10" item="masonryGrid_SlideFromLeft" grid_id="vc_gid:1458178666639-80ebf3775500c87d35de078c3422fe96-10" taxonomies="555"]
Let say the page ID is 4269, this is the generated HTML code on front-end:
<!-- vc_grid start -->
<div class="vc_grid-container-wrapper vc_clearfix">
<div class="vc_grid-container vc_clearfix wpb_content_element vc_masonry_grid" data-initial-loading-animation="zoomIn" data-vc-grid-settings="{"page_id":4269,"style":"all-masonry","action":"vc_get_vc_grid_data","shortcode_id":"1458178666639-80ebf3775500c87d35de078c3422fe96-10","tag":"vc_masonry_grid"}" data-vc-request="http://example.com/wp-admin/admin-ajax.php" data-vc-post-id="4269" data-vc-public-nonce="0641473b09">
</div>
</div>
<!-- vc_grid end -->
Now, if page_id and shortcode_id don't match each other, {'status':'Nothing found - $shorcode_id'} will be throw out and no contents will be displayed.
You can find out more inside vc_grid.min.js file.
2. Solution:
Generate a fake page with VC, then copy generated html code to your template file.
Create a template with VC directly.
Use Shorcode Mapper to create your own shorcode.
First you build a new page and add a grid post on it,
then we get
_vc_post_settings
post meta , and try to build a new one
then update post meta data
now we can by pass VC Ajax security check
in the following code "1513628284966-37b8c3ca-d8ec-1" is VC generated guid
you should change it to yours .
$meta = get_post_meta(1365,'_vc_post_settings');
$settings = array();
#$settings['vc_grid_id'] = $meta[0]['vc_grid_id'];
$key = random_int(1513628284966,9513628284966);
$settings['vc_grid_id']['shortcodes'][''.$key.'-37b8c3ca-d8ec-1'] = $meta[0]['vc_grid_id']['shortcodes']['1513628284966-37b8c3ca-d8ec-1'];
$settings['vc_grid_id']['shortcodes'][''.$key.'-37b8c3ca-d8ec-1']['atts']['custom_query'] = "tag=shop";
$settings['vc_grid_id']['shortcodes'][''.$key.'-37b8c3ca-d8ec-1']['atts']['grid_id'] = ''.$key.'-37b8c3ca-d8ec-1';
$n = add_post_meta(1365,'_vc_post_settings',$settings);
return do_shortcode("[vc_basic_grid post_type=\"custom\" show_filter=\"yes\" filter_style=\"dropdown\" item=\"5959\" grid_id=\"vc_gid:".$key."-37b8c3ca-d8ec-1\" filter_source=\"post_tag\" custom_query='tag=".$tag."']");
I've solved.
I had the same problems, with the Visual Composer Editor offered by WpBakery
https://wpbakery.com/
and after understanding the connection between the IDs of the block, and the ID of the Post, I put more attention to the settings of the Block.
There is infact one field called "Element ID", and here we have to put our ID of the Post we are editing.
In my case the Block was a block containing some Posts.
After saving, and viewing the page without the Editor, I was finally able to see the block, and not the message
{"status":"Nothing found"}
I found a solution to this problem.
I modified the woocommerce category template and linked to the woocommerce_archive_description hook to add additional descriptions from some pages, for this I got their id, and then display the content.
echo do_shortcode($post->post_content);
The gallery(media grid) didn't work because there was a mismatch between the page id and the shortcode id. Therefore, the logical solution was to redefine the global variable $post to the $post of the page from which I get the content.
global $post;
$post = get_post( $id );
And it turns out that the post id matches.
After that, don't forget to return the normal $post value;
wp_reset_postdata();
By the way - use this option to load custom styles for wpbakery elements.
echo '<style type="text/css" data-type="vc_shortcodes-custom-css">' . get_post_meta( $id, '_wpb_shortcodes_custom_css', true ) . '</style>';
The whole code
function extra_product_category_desc(){
if( is_product_category() ){
$id = get_term_meta (get_queried_object()->term_id, 'pageId', true);
if($id !== ''){
global $post;
$post = get_post( $id );
echo do_shortcode($post->post_content);
echo '<style type="text/css" data-type="vc_shortcodes-custom-css">' . get_post_meta( $id, '_wpb_shortcodes_custom_css', true ) . '</style>';
wp_reset_postdata();
}
}
}
add_action( 'woocommerce_archive_description', 'extra_product_category_desc', 11 );
You may also try with do_shortcode('');
Like
do_shortcode('[vc_basic_grid post_type="post_type" max_items="10" item="masonryGrid_SlideFromLeft" grid_id="vc_gid:1458178666639-80ebf3775500c87d35de078c3422fe96-10" taxonomies="555"]');

Change Wordpress feed <link> for one specific tag

I have an external page that reads a RSS feed for a tag. I can't change anything on the external page, so the challenge is to change the RSS feed on my side to match the requirements.
On the external page the 3 latest posts for a tag are shown, and at the end of the section (note: not after each post but after all 3 posts) there is a "View all" link. This link receives its value from the element in the feed, which is by default set to my blog homepage, e.g. http://myblog.com). For this specific tag the link should be http://myblog.com/tag/myspecialtag.
The requirement is that the "View all" link links to the tag page instead of the homepage.
My idea was to add a condition to the element to change the URL for this specific category. I tried to change the feed template as recommended here: Customizing feeds, but for some reason it doesn't change the template at all. The code I tried is the following:
remove_all_actions( 'do_feed_rss2' );
add_action( 'do_feed_rss2', 'change_feed_rss2', 10, 1 );
function change_feed_rss2( $for_comments ) {
$rss_template = get_template_directory() . '/feeds/feed-custom_rss2.php';
if( file_exists( $rss_template ) )
load_template( $rss_template );
else
do_feed_rss2( $for_comments ); // Call default function
}
Of course I created the custom feed template and stored it in the feeds directory in my theme.
As this didn't work I tried looking into filters/hooks but I couldn't find anything helpful regarding my issue. Any ideas on how to best solve this issue?
I came up with the following solution:
I created a new custom page template custom_rss-feed.php and copied the code from wp-includes/feed-rss.php into it. I assigned this template to a new page. Additionally I added a filter to get_bloginfo_rss like the following:
function alter_bloginfo_rss($value, $key) {
if ( $key === "url" &&
is_page_template("custom_rss-feed.php")
) {
return $value . "/my/custom/url";
}
return $value;
}
add_filter("get_bloginfo_rss", "alter_bloginfo_rss", 10, 2);

Replacing only parts of an archive and single page template of WordPress

I am having a bit of trouble here understanding how to do the following. I have searched for weeks now but cannot seem to find what I am looking for.
I have a custom post type 'product' and want to change which template gets loaded for the single product page as well as the archive for the products. I am using the following code to load include and load templates.
add_filter('template_include', function() {
if (is_post_type_archive('product')) {
$templatefilename = 'archive-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
return $template;
}
if ('product' == get_post_type() ){
$templatefilename = 'single-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
return $template;
}
});
The problem I am having is that it replaces the current theme's template instead of just the inner part of the content and archive areas.
Here is what I want to achieve:
Create a custom post type 'product' in a plugin - DONE (Was kinda easy!)
When opening a single product only change the content part. - I can do this with the_content filter hook. Simple enough. Any other suggestions is welcome.
When I go to the archive view for the 'product' custom post type I don't want to have it load the theme's default archive (list) view but instead a grid view from my plugin which I cannot seem to get right. I only want to change the inner part of the template, not the whole page.
I have created this plugin a few weeks ago using only shortcodes which works good but want to see if I can do it without the use of shortcodes by means of creating the custom post type and changing the inner template parts of the current active theme.
Can anybody steer me into the right direction here?
If I create a theme I can do what I am looking for but I want to create this into a plugin instead without adding or making changes to the active theme. The plugin should handle what is needed.
The same issue is discussed here but what I want is to develop something that is theme independent. No changes should be made in theme files and no theme files should be copied to the plugin.
WP - Use file in plugin directory as custom Page Template?
Recently I also had the same problem. Here's how I worked it out.
template_include filter accepts a parameter which is the selected template that you want to override (this what you are missing in your code).
I don't know but sometimes the filter hook need higher priority to work like 9999. But first check if it work with default priority, if don't change it.
I assume your both archive and single product template both have include get_header() and get_footer() which can be used for default selected theme (Or if the theme has different setup, setup accordingly).
This is simplified code:
add_filter('template_include', function($default_template) {
if (is_post_type_archive('product')) {
$templatefilename = 'archive-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
$default_template = $template;
} else if ('product' == get_post_type() ) {
$templatefilename = 'single-product.php';
$template = WPVS_PATH . 'templates/' . $templatefilename;
$default_template = $template;
}
// Load new template also fallback if both condition fails load default
return $default_template;
}, 9999); // set priority, only if not worked with default one
The best option in this case is to provide a shortcode to the user. So they can place it on any page that they want (or that you auto generate). That way you will place your content inside their theme.
Something like this:
add_shortcode( 'slotsl-game', 'embed_game' );
/**
* Print the game
* #return false|string
*/
function embed_game(){
ob_start();
$game = get_post();
include_once SLOTSL_PLUGIN_DIR . 'templates/slotsl-single-game.php';
return ob_get_clean();
}

is there a way (plugin) to insert html/css/images ect automatically into every wordpress post?

is there a way (plugin) to insert html/css/images ect.. automatically into every wordpress post? most of my posts are going to be very similar so is there a plugin that will automatically insert the pre written html/css/ ect in every post as opposed to me entering it manually every time.
Thank you in advance ;-)
You can write your own simple function for this, see my example below:
add_filter( 'default_content', 'my_editor_content' );
function my_editor_content( $content ) {
global $post_type;
if( $post_type == 'post') { /* Or your custom post type, pages etc. */
$content = 'Your custom HTML/CSS content here';
}
return $content;
}
Place this in functions.php and it will be the default content of every new post/page/custom post type you create.
For a list of available post types, please refer to the Codex
You could use a plugin such as Ad injection, it will allow you to do what you need without having to alter / amend / ad any code to the templates or files
