Say you created your own Gallery plugin that uses it's own shortcode (eg: [my_gallery] )
How would you go about modifying the default WordPress gallery shortcode insertion within the editor of [gallery] to [my_gallery] so that the client is not confused with having to remember the custom shortcode and accidentally making incorrect gallery insertions?
first remove the gallery shortcode , and then add your own ...
remove_shortcode('gallery', 'gallery_shortcode'); // removes the original shortcode
add_shortcode('gallery', 'my_awesome_gallery_shortcode'); // add your own shortcode
function my_awesome_gallery_shortcode($attr) {
$output = 'Codex is your friend' ;
return $output;
}
or as an alternative just rename your shortcode to something less confusing :-)

So, I know you can put:
function page_title_sc( ){
return get_the_title();
}
add_shortcode( 'page_title', 'page_title_sc' );
Into function.php to fetch the page title and get a [page_title] shortcode within Wordpress, but is it possible to do exactly that for keywords?
I put a focus keyword down in Yoast SEO and I would like to have a shortcode for that.
Or another idea: is there a way to have a custom shortcode field in every page? So that I only have to put something into that once and can use it as a shortcode within the whole page?
If you want a shortcode for Yoast to output the keyphrase automatically:
function wpso_61018203_output_yoast_keyphrase() {
// Make sure Yoast is installed/active.
if ( class_exists( 'WPSEO_Meta' ) ) :
// Hold the global post object.
global $post;
return WPSEO_Meta::get_value( 'focuskw', $post->ID );
endif;
}
add_shortcode('yoast_kw', 'wpso_61018203_output_yoast_keyphrase' );
You can then do this ['yoast_kw'] in your content, or use echo do_shortcode('[yoast_kw]'); in your template.
Use get_post_meta and grab _yoast_wpseo_focuskw:
function page_focus_keyword( ){
return get_post_meta(get_the_ID(), '_yoast_wpseo_focuskw');
}
add_shortcode( 'focus_keyword', 'page_focus_keyword' );
WordPress filters all content to make sure that no one uses posts and page content to insert malicious code in the database. This means that you can write basic HTML in your posts, but you cannot write PHP code.
And you want to use Wordpress shortcode for focus keyword.
Possible solution given on Wordpress.org Yoast SEO plugin support query on similar query, and checkout the linked solution
insert the below php snippet in functions.php
if(!function_exists('wpseoFocusKW'))
{
function wpseoFocusKW()
{
$focuskw = wpseo_get_value('focuskw', $post->ID);
echo $focuskw;
}
}
And to use the shortcode in another page for focused keyword, insert the below shortcode in any pages with yoast-seo plugin :
Shortcode for focus keyword
[<?php wpseoFocusKW();?>]
I am new to WordPress.org and I figured out that I can add HTML, CSS and Javascript to a page via a code block. But my question is, can I also make a call to the WordPress database from a page? Or do I need to make a plugin for that?
You can do this with a shortcode that calls a php function in your (child-themes) functions.php.
This is a good guide to start from:
https://www.wpbeginner.com/wp-tutorials/how-to-add-a-shortcode-in-wordpress/
// function that runs when shortcode is called
function wpb_demo_shortcode() {
// Things that you want to do.
$message = 'Hello world!';
// Output needs to be return
return $message;
}
// register shortcode
add_shortcode('greeting', 'wpb_demo_shortcode');
And then call it within your post/page (in a Gutenberg shortcode block)
[greeting]
This is a good way because you can re-use and maintain it easily.

Using page you can call database you can do it using
Creating a template and assign that template in wordpress page
Or you can create short code in function.php and add shortcode in your wordpress page
Create page template
1) Create file in your theme folder and name it 'custom.php' you can name it anything.
2) Open file and add this
3) Start editing in that page you can call database using
global $wpdb;
$result = $wpdb->get_results('SELECT * FROM wp_posts LIMIT 10');
4) After editing 'custom.php' you can assign this template in your custom page
note: please refer this link to know more about page template
https://www.cloudways.com/blog/creating-custom-page-template-in-wordpress/
Create short code in function.php
1) You can create shortcode using
// function that runs when shortcode is called
function wpb_demo_shortcode() {
global $wpdb;
$result = $wpdb->get_results('SELECT * FROM wp_posts LIMIT 10');
return $result;
}
// register shortcode
add_shortcode('get_post_shortcode', 'wpb_demo_shortcode');
2) you can call shortcode in any page of wordpress.
<?php echo do_shortcode("[get_post_shortcode]"); ?>
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();
$game = get_post();
include_once SLOTSL_PLUGIN_DIR . 'templates/slotsl-single-game.php';
return ob_get_clean();
}
I'm trying to run a do_shortcode in functions.php with no luck
I'm using Types plugin http://wp-types.com/ for creating custom post types and custom fields.
What I'm trying do is adding a custom column in admin for view all custom posts that displays a thumbnail from a custom field.
This is what I got so far, but it seems that the shortcode doesn't work inside functions.php
// add a column for custom post type (products)
add_filter('manage_product_posts_columns', 'add_thumbnail_column');
add_action('manage_product_posts_custom_column', 'add_thumbnail_content', 10, 2);
function add_thumbnail_column($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.
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
