I've recently purchased the events plus Wordpress plugin from http://wpeventsplus.com/ and am trying to get the calendar to show up on a template page. However, the shortcode [PLUS_CALENDAR] is not working on the template page I wrote. Here's my entire code for that page:
<?php
/*
Template Name: page-registration
*/
?>
<?php get_header(); ?>
<?php if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} // end if
?>
<?php get_footer(); ?>
My background is in HTML and CSS, and I'm not familiar with php much at all. I should also mention that my site is WP Theme converted from a normal HTML site, making it a little harder to work with plugins, as the code was not converted in a very clean way to php. I'm guessing I have a mistake, or a few, in my code, but I have no idea where to start looking, I'd appreciate any help. Thanks.
You can execute a shortcode in a WordPress PHP file this way:
<?php echo do_shortcode('[PLUS_CALENDAR]'); ?>
Details: https://developer.wordpress.org/reference/functions/do_shortcode/
So your code becomes:
<?php
/*
Template Name: page-registration
*/
?>
<?php get_header(); ?>
<?php if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
echo do_shortcode('[PLUS_CALENDAR]');
//
} // end while
} // end if
?>
<?php get_footer(); ?>

I want to extract the images contained in a gallery block while maintaining their correct order. Since get_children() and get_attached_media() do not seem to register when the image order is changed in wp-admin, I'm trying to use get_post_gallery() instead.
My problem is that the function returns false, even though the post does have a gallery.
I tried both the example and the plain usage from Codex. Currently, my entire single.php looks like this:
<?php
get_header(); //html head etc
if (have_posts()): while (have_posts()) : the_post(); //the loop
if ( get_post_gallery() ) :
echo get_post_gallery();
else :
echo (the_ID() . " has no gallery.");
endif;
endwhile;
endif;
?>
… which results in "ID has no gallery" every time.
However, the output of print_r($post->post_content); does include the following, which seems to confirm that there is in a fact a gallery:
<!-- wp:gallery {"ids":[80,81,82]} -->
<figure class="wp-block-gallery columns-3 is-cropped">
<ul class ="blocks-gallery-grid">
<!-- … -->
I'm also attaching a screenshot from wp-admin to make sure I don't misunderstand what constitutes a gallery.
get_post_gallery() works only for native galleries which have been created in classig WYSIWYG editor. You can find more about it there. Hovewer, if you create Gallery via Gutenberg, it create the whole HTML code instead of classic editor gallery which create shortcode like this: [gallery ids="400097,400052,400051"] . Functions get_post_gallery(), get_post_galleries() and get_post_gallery_images() works only on classic galleries added via native shortcode.
Are you only trying to display the gallery block as opposed to all content? If so, maybe try this?
<?php
get_header(); //html head etc
if (have_posts()): while (have_posts()) : the_post(); //the loop
if (has_block('gallery', $post->post_content)) {
echo 'yes, there is a gallery';
$post_blocks = parse_blocks($post->post_content);
foreach ($post_blocks as $post_block){
if ($post_block['blockName'] == 'core/gallery'){
echo do_shortcode( $post_block['innerHTML'] );
}
}
}
// if there is not a gallery block do this
else {
echo 'no gallery';
}
endwhile;
endif;
get_footer();
?>
I got some inspiration from reading this post btw.
I'm looking for a possibility to add a custom html block/post to the woocommerce "shop page" inside the products grid, as a product.
What I mean.. I have a grid of products on the "shop" page (archive-product) and I want to create a special post/page/html block with some text information, that will be inserted into the products grid as a one of "product", but with no price, with no title and unclickable. I've attached the screenshot of the final result I want to have, it's really self explaining - here it is exactly what I'm looking for.
As an idea probably I can create a special product with specific slug or title and the corresponding script with pre_get_posts hook will find this post/product and modify it to look like I need. I'm looking for some code/ideas how to insert this specific block/page/post into the archive-product page on some position in the grid. Thanks!
Thanks for help, guys! I've implemented the functionality I was looking for. I've found the corresponding loop in archive-product.php and as was suggested by JapanGuy, I've added a simple "if i equal let's say 5 then echo < li>[Custom block]< /li>" .
The original snippet from archive-product.php:
<?php woocommerce_product_loop_start(); ?>
<?php woocommerce_product_subcategories(); ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php wc_get_template_part( 'content', 'product' ); ?>
<?php endwhile; // end of the loop. ?>
<?php woocommerce_product_loop_end(); ?>
Modified code with inserted custom block:
<?php woocommerce_product_loop_start(); ?>
<?php woocommerce_product_subcategories(); ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php
if ($i == 5) {
echo "<li>[Custom block]</li>";
}
$i++;
?>
<?php wc_get_template_part( 'content', 'product' ); ?>
<?php endwhile; // end of the loop. ?>
<?php woocommerce_product_loop_end(); ?>
Im such simple way I can add any content to the created [Custom block] and have an usual products grid with extra custom designed block. I'm not very experienced programmer, so probably my code is not perfect, but it works. Thanks!
Edit: Previous code was wrong, changed it here
$i=0;
while ($row = mysqli_fetch_array($query))
{
if ($i == 2) {
echo "Cusom block";
}
echo "<p> Product block " . $row['column'] . " </p>";
$i++;
}
Creating WordPress Custom Post Archives : Hope this meets your requirement.
Custom Post Archives list your custom content. You probably already know the standard WordPress archives. So you can follow this to display both together .

What is best practice for making a function call on a wordpress page?
For instance if you want to call my_special_function(); on the home page, where is the proper place to put the function call (ie home-page.php, /template-parts/content-page.php etc.).
<?php if( function_exists( my_special_function ) ) {
my_special_function();
} ?>
FYI Im using Underscores theme.
I've seen a few comments regarding shortcode. Would something like the below WP page template with the shortcode inserted be a best practice over just calling the function on that page?
So if I wanted the function to be called in the page template below I would just insert the shortcode wherever I want it on that page template or just is just calling the function is sufficient or best practice
<?php
/**
* Template Name: Home Page
*
* The template for displaying the home page.
*
* #link https://codex.wordpress.org/Template_Hierarchy
*
* #package Rollins_Ridge
*/
get_header(); ?>
<div id="primary" class="content-area">
<main id="main" class="site-main" role="main">
// insert Shortcode
<?php echo do_shortcode('[special_function_shortcode]') ;?>
// or just call the function
my_special_function();
// or something else im not aware of
code here;
<?php
while ( have_posts() ) : the_post();
get_template_part( 'template-parts/content', 'page' );
// If comments are open or we have at least one comment, load up the comment template.
if ( comments_open() || get_comments_number() ) :
comments_template();
endif;
endwhile; // End of the loop ?>
</main><!-- #main -->
</div><!-- #primary -->
<?php
get_footer();
Don't edit themes core files.
the proper way is using functions.php file in child theme directory.
you can add your function in this file and create shortocde using wordpress hook
like
my_special_function(){
//Your content goes here.
echo "This is proper way";
}
add_shortcode('special_function_shortcode','my_special_function');
and use following shortocde anywhere on site.
in wordpress page use [special_function_shortcode]
and in php use
<?php echo do_shortcode('[special_function_shortcode]') ;?>
Im forced to work with wordpress, and if you work with it, you probably know what i mean:
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
Its working, no question. But i do not understand what this actually means. Its not a ternary operator nor anything else i know. Ive never seen a statement like this in any php-projects ive worked on. So i got several questions:
What is this line exactly doing? I know that it gets all posts, iterates over them and ... what is this the_post() doing? And what are these doubledots doing?
Is this Wordpress-Only or could it be used somwhere else too?
Where is the current post stored?
Ive already googled it, but there are no information regarding my problem, noone seems to be interested in how wordpress works. I am, but i do not get it. If somebody got an explanation for me, it would be great.
<?php define('WP_USE_THEMES', false); get_header(); ?>
The loop starts here:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
and ends here:
<?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>
This is using PHP's alternative syntax for control structures, and could also be expressed as:
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} // end if
?>
the post()
This function does not accept any parameters.
Return Values
This function does not return any values.
<?php
while ( have_posts() ) : the_post();
echo '<h2>';
the_title();
echo '</h2>';
the_content();
endwhile;
?>
have_posts()
Parameters
This function does not accept any parameters.
Return Values
(boolean)
True on success, false on failure.
Examples
The following example can be used to determine if any posts exist, and if they do, loop through them.
<?php
if ( have_posts() ) :
while ( have_posts() ) : the_post();
// Your loop code
endwhile;
else :
echo wpautop( 'Sorry, no posts were found' );
endif;
?>
Note
Calling this function within the loop will cause an infinite loop. For example, see the following code:
<?php
while ( have_posts() ): the_post();
// Display post
if ( have_posts() ): // If this is the last post, the loop will start over
// Do something if this isn't the last post
endif;
endwhile;
?>
If you want to check if there are more posts in the current loop without this unfortunate side effect, you can use this function.
function more_posts() {
global $wp_query;
return $wp_query->current_post + 1 < $wp_query->post_count;
}
1. What is LOOP
The Loop is PHP code used by WordPress to display posts. Using The Loop, WordPress processes each post to be displayed on the current page, and formats it according to how it matches specified criteria within The Loop tags.
It will fetch data related to specific page
:(colon) is used to tell condition/loop starts from here. You can replace it with { }(bracket quotes)
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} // end if
?>
2. Is this Wordpress-Only or could it be used somwhere else too?
yes of course you can use it.
You can access full wordpress functionality by including one core file with name of "wp-blog-header.php" that is located on root of wordpress directory.
<?php
/* Short and sweet */
define('WP_USE_THEMES', false);
require('./wp-blog-header.php');
?>
Include this file in the top of your external file, you can access wordpress database, wordpress function , wordpress hooks too.
3. Where is the current post stored?
11 default tables are existed in wordpress database. You can see wp_posts table in database. all posts are store in this table.
suppose, if your are creating meta tag in your post, it will store in wp_postmeta
It's just an alternative syntax for:
if ( have_posts() ) { //open if
while ( have_posts() ) { //start while loop
the_post(); //call a function
See http://php.net/manual/en/control-structures.alternative-syntax.php
It's not wordpress specific and can be used in any php code.
To whom it may concern.
What is WordPress Loop?
When we save data inside WordPress(posts, pages, almost everything) data gets saved as a row inside our database fx. MySQL.
WordPress dynamically query the database and finds which row corresponds to the page you are on, and pulls that data then displays it in that section.
As this is a dynamic query and executed in a repeated manner, it is called a WordPress Loop
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
What are these doubledots doing? condition/loop starts from here :(colon) and is a ternary operators.
I think rest of the questions has been answered by others.
I am creating a wordpress template and I now need some code that creates a loop to show all posts but not full posts, just excerpts.
Can anyone help please?
Use this code to generate the excerpt into the loop:
<?php
if(have_posts())
{
while(have_posts())
{
the_post();
the_excerpt();
}
}
?>
The above will generate only the excerpt of the posts. If you need extra options like post title, date, author and more you have to read the WordPress codex. http://codex.wordpress.org/Main_Page
You can read more by following the link given by markratledge below.
Everything you need to know - with examples - is here: http://codex.wordpress.org/The_Loop
The most basic loop is
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
//
// Post Content here
//
} // end while
} // end if
?>
and you want to use the_excerpt() instead of the_content() See http://codex.wordpress.org/Function_Reference/the_excerpt
