woocommerce get_available_variations() stripping slashes - woocommerce

I want to display variations in a list format and i've implemented the code below
$variations = $product->get_available_variations();
foreach ($variations as $key => $value) {
echo "<li><span data-slug='".implode('/', $value['attributes'])."'>".esc_html( apply_filters( 'woocommerce_variation_option_name', str_replace("-"," ",implode(' ', $value['attributes'])) ) ) ."</span></li>";
}
The problem is the website i'm working on has attributes such as; 30/50, 40/50. When they are returned, they are displayed without a slash so 3050, 4050.
How do i solve this so they include the slash?

You must replace each slash sign in the string with an HTML entity code. The code for a forward slash is: /

Output certain product page on homepage / WooCommerce shortcode not working properly

I need to output a certain product page on the homepage. add_rewrite_rule doesn't work for homepage for any reason (
there are actually no rewrite rules for the homepage in the database, WordPress seems to use some other functions to
query the homepage):
//works fine
add_rewrite_rule( 'certainproductpage/?$',
'index.php?post_type=product&name=certainproduct',
'top'
);
//does not work
add_rewrite_rule( '', //tried everything like "/", "/?$" etc
'index.php?post_type=product&name=certainproduct',
'top'
);
After spending way too much time looking through wp / wc core code and stackoverflow I came across an alternative. I can
simply add a shortcode in the content of the page I need to be the homepage and a product page at the same
time: [product_page id=815]. Indeed it works great, but only if the shortcode is added in the admin editor or is
stored in the database (post_content). If I try to call the shortcode manually on the page template (
page-certainproductpage.php) then it outputs the product page without some necessary stuff (PayPal, PhotoSwipe and
Gallery js). Weirdly enough, if I keep the shortcode in the content (via Gutenberg / Code Editor) but don't
call the_content and only echo the shortcode then everything works fine:
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
get_header( 'shop' );
//works fine only if the same shortcode is within the certainproductpage's content
echo do_shortcode("[product_page id='815']");
//the_content();
get_footer( 'shop' );
Also when I try to add the shortcode via the_content filter hook before the do_shortcode function is applied in core's
default-filters.php ($priority < 11), then I get only the error:
NOTICE: PHP message: PHP Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/html/wp-includes/functions.php on line 5106
Unfortunately there is no stack trace logged. And the function around line 5107 is wp_ob_end_flush_all which is called on shutdown from default-filters.php
echo do_shortcode(apply_filters('the_content', "[product_page id=815]")); did not help either (same incomplete output as
with echo do_shortcode("[product_page id=815]");)
Also totally weird:
When I compare the string of the content from the editor and the string of the shortcode added programmatically it is
equal!:
add_filter( "the_content", function ( $content ){
$wtf = "<!-- wp:paragraph -->
<p>[product_page id=815]</p>
<!-- /wp:paragraph -->";
$result = $wtf === $content;
?><pre><?php var_dump($result)?></pre><?php
return $content;
}, 1 );
But if I replace return $content with return $wtf - I get the maximimum exucution time exceeded error.
So how can I properly output a product page on the homepage ("/") or how can I get the same result with the shortcode
when applied within the the_content filter as when just adding the shortcode in the (Gutenberg) editor?
Update
Tested it with a simple custom shortcode outputting only a heading tag and it works fine with the_content filter. Also tried it on an absolutely clean site with only WooCommerce and PayPal installed - with the same results. Seems to be a bug on the WooCommerce side. Gonna run it through xDebug some day this week.
Ok, found a bit of a hacky solution. I just check on every page load whether the homepage is currently queried or not. Then I get the page content and check if it already contains the shortcode. If not then the page content gets updated in the database with the shortcode appended.
//it has to be a hook which loads everything needed for the wp_update_post function
//but at the same time has not global $post set yet
//if global $post is already set, the "certainproductpage" will load content not modified by the following code
add_action( "wp_loaded", function () {
//check if homepage
//there seems to be no other simple method to check which page is currently queried at this point
if ( $_SERVER["REQUEST_URI"] === "/" ) {
$page = get_post(get_option('page_on_front'));
$product = get_page_by_path( "certainproduct", OBJECT, "product" );
if ( $page && $product ) {
$page_content = $page->post_content;
$product_id = $product->ID;
$shortcode = "[product_page id=$product_id]";
//add shortcode to the database's post_content if not already done
$contains_shortcode = strpos( $page_content, $shortcode ) > - 1;
if ( ! $contains_shortcode ) {
$shortcode_block = <<<EOT
<!-- wp:shortcode -->
{$shortcode}
<!-- /wp:shortcode -->
EOT;
$new_content = $page_content . $shortcode_block;
wp_update_post( array(
'ID' => $page->ID,
'post_content' => $new_content,
'post_status' => "publish"
) );
}
}
}
} );
I'd recommend one step at a time. First of all, does this work?
add_filter( "the_content", function ( $content ) {
$content .= do_shortcode( '[product_page id=815]' );
return $content;
}, 1 );
This should append a product page to every WordPress page/post.
If it works, then you need to limit it to the homepage only, by using is_front_page() conditional in case it's a static page:
add_filter( "the_content", function ( $content ) {
if ( is_front_page() ) {
$content .= do_shortcode( '[product_page id=815]' );
}
return $content;
}, 1 );
If this works too, then we'll see how to return a Gutenberg paragraph block, but not sure why you'd need that, so maybe give us more context

How to use "has_term" correctly

Im working with the single product page and I need to have a different image (depending on the category) after the add to cart button.
I tried this code but it doesn't show me the image that I need
add_action ( 'woocommerce_after_add_to_cart_button', 'content_after_button' );
function content_after_button() {
if (has_term( 'Categoria', 'Accesorios' ) ) {
echo 'https://prueba.soygorrion.com.ar/wp-content/uploads/2019/08/iconos2.jpg';
}
I think im using has_term in the wrong way.
What im trying to accomplish is:
I have a parent category that is "Accesorios" and inside that I have other child categories like "Billeteras". For each one of this child categories it has to show a diferent image.
thank you
First of all there is issue with your has_term checking. If you check has_term docs, you can find it takes first parameter as category term and second parameter as taxonomy.
Add secondly you are just echo image url that is not going to display image.
So, do as follows -
add_action ( 'woocommerce_after_add_to_cart_button', 'content_after_button' );
function content_after_button() {
// do check with has_term( $term = '', $taxonomy = '', $post = null )
if( has_term( 'Accesorios', 'product_cat' ) ) {
echo '<img src="https://prueba.soygorrion.com.ar/wp-content/uploads/2019/08/iconos2.jpg" />';
}
}
Since you mentioned that the problem is with has_term function. If you can get the product ID inside add to cart, then you can use this code to get categories and check them:
$categories = wp_get_post_terms($product_id, 'product_cat');
if(in_array("Accesorios", $categories))
{
echo "bla bla";
}
I have tested this code for another purpose, it works fine. I hope this will help. Please inform me when you test it and if you face any errors update your question with your new code.

Add a symbol before every single category inside a list display categories widget - Wordpress - WP_Widget_Categories

I want to add a symbol (the Hash symbol - #) before every category displayed inside the list display categoris widget in wordpress.
I am not adding the WP_Widget_Categories code to the post question because it is the very basic one that anyone will find with wordpress.
Anyway I am trying to make something like this:
Example
That's all. I started to study php from a few days and I don't know how to do this, any help will be really appriciated.
You can use a filter to modify the results generated by the default categories widget. Try adding this in your functions file:
function modify_widget_categories_listing( $content ) {
return "#$content";
}
add_filter( 'list_cats', 'modify_widget_categories_listing', 10, 2 );
You may have to make some changes to what is being returned to get exactly what you're looking for, but that's the gist of it.
Put this in your functions.php
function show_categories_with_hash() {
$terms = get_terms( 'categories' );
echo '<ul>';
foreach ( $terms as $term ) {
$term_link = get_term_link( $term );
if ( is_wp_error( $term_link ) ) {
continue;
}
echo '<li>#' . $term->name . '</li>';
}
echo '</ul>';
}

Wordpress next_posts_link Linking to wrong URL

I have next_posts_link setup on the single.php, and it generates the following URL:
http://mywebsite.com/news/article1/page/2
However, this url would be redirected to
http://mywebsite.com/news/article1
Any way to get to the second page?
It seems that it's an issue with Wordpress permalinks. I currently use a custom permalink structure
/%category%/%postname%/
Setting the permalinks as default fixes this issue, but this project needs to have the custom permalinks.
You should be using next_post_link() which is meant to navigate between single posts. next_posts_link naviugate between pages
If you however need to navigate a paged post (using <--nextpage-->), then you should make use of wp_link_pages
EDIT
I have recently did the same exact thing on WPSE. As I explain in that post, the structure you need is not available for any permalink structure outside the default permalink structure.
Just a note before I paste that answer, I have done that for the /%postname%/ permalink structure. Just change all instances of /%postname%/ to the appropriate structure
POST FROM WPSE
As I said, this whole setup you are after is not possible natively with pretty permalinks. Your setup probably works with default permalink structure as both queries (the main query and your custom query) read these permalinks in the same way. When you switch to pretty permalinks, the two queries on the single page interpret the URL differently causing one or the other to fail when you try to paginate your custom query
Single pages was never meant to be paginated in this manner, specially using pretty permalinks. I have gone and played around with a couple of ideas, and the best way to accomplish this is
To write your own pagination functions that can read the page number from the URL
Write your own function that can append the page number to the URL, something like adding /2/ to the URL of single pages.
I must stress, if you are paginating single post with <!--nextpage-->, your post will also paginate together with your custom query. Also, if your permalink structure is not set to /%postname%/, the code will fail and display an error message through wp_die()
THE CODE
Here is the code that will get the next/previous page and also add the pagenumber to the URL.
function get_single_pagination_link( $pagenum = 1 ) {
global $wp_rewrite;
if( is_singular() && $wp_rewrite->permalink_structure == '/%postname%/') {
$pagenum = (int) $pagenum;
$post_id = get_queried_object_id();
$request = get_permalink( $post_id );
if ( $pagenum > 1 ) {
$request = trailingslashit( $request ) . user_trailingslashit( $pagenum );
}
return esc_url( $request );
}else{
wp_die( '<strong>The function get_single_pagination_link() requires that your permalinks are set to /%postname%/</strong>' );
}
}
You can use this function as follow to get the link for any page in the single page when paginating your custom query
get_single_pagination_link( 'pagenumber_of_previous_or_next_page' );
Again, as I said, there is no pagination function that will be able to paginate your custom query or read pagenumbers from the URL, so you have to write your own.
Here is my idea of creating links to the next and previous pages in your custom query. If you look closely, you will see how I have used the previous declared function get_single_pagination_link() to get the links to the next and previous pages
function get_next_single_page_link ( $label = null, $max_page = 0 ) {
global $wp_query;
if ( !$max_page ) {
$max_page = $wp_query->max_num_pages;
}
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
if( is_singular() ) {
$next_page = intval($paged) + 1;
if ( null === $label ) {
$label = __( 'Next Page »' );
}
if ( ( $next_page <= $max_page ) ) {
return '' . $label . '';
}
}
}
function get_previous_single_page_link( $label = null ) {
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
if( is_singular() ) {
$prev_page = intval($paged) - 1;
if ( null === $label ) {
$label = __( '« Previous Page' );
}
if ( ( $prev_page > 0 ) ) {
return '' . $label . '';
}
}
}
You can now use this two functions in your code to paginate your custom query. Both functions work exactly the same as get_next_posts_link() and get_previous_posts_link() and uses the same exact parameters, so you'll need to keep in mind that you need to pass the $max_page parameter for your custom query
Here is your custom query with these functions.
function get_related_author_posts() {
global $authordata, $post;
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
$args = array(
'posts_per_page' => 2,
'paged' => $paged
);
$authors_posts = new WP_Query( $args );
$output = '';
if( $authors_posts->have_posts() ) {
$output = '<ul>';
while( $authors_posts->have_posts() ) {
$authors_posts->the_post();
$output .= '<li>' . get_the_title() . '' . get_the_excerpt() . '</li>';
}
$output .= '</ul>';
$output .= get_previous_single_page_link();
$output .= get_next_single_page_link( null , $authors_posts->max_num_pages );
wp_reset_postdata();
}
return $output;
}
If you want your long post to be shown 2 or 3 pages . You just have to add <!--nextpage--> in your post . The content after it will be shown in the next page . Reference

Custom Fields/Values displaying out of order

I'm using the Types Wordpress plugin to enable custom fields. The plugin allows you to rearrange the order of the images in the admin page editor. Here's my code in my single.php to display multiple images in the custom field and have a link to itself to also use Fancybox:
<?php
$mykey_values_img = get_post_custom_values('wpcf-image');
if ($mykey_values_img != null) {
foreach ( $mykey_values_img as $key => $value ) {
?>
<img src="<?php echo $value; ?>" />
<?php
} //foreach
} //if
?>
Problem:
Right now this code works perfectly on my local copy running on MAMP. However, when I put it online hosted on iPage, the images are out of order. I don't know what's causing this discrepancy. When I use the shortcode from Types to display the images instead of the php above they are in order, but I don't have the option of using Fancybox. I was also wondering if there is a better way to display an image from Wordpress that will insert the alt tag for the image.
I just encountered this problem too, and your first answer led me to a tighter solution.
I also used types_render_field(), but if you include a 'raw' parameter, you can avoid the string manipulation.
$images_raw = types_render_field('image', array('raw'=>'true','separator'=>';'));
$images = explode(';', $images_raw);
foreach ($images as $link) {
echo '' . $link . '">"';
}
Then, if you're nasty, you can get the ID of the attachment from its SRC. Using that ID, you can get all the info you need about that attachment, like a caption, or whatnot.
I figured out a work around to get it working. Its not ideal but it works.
The Types plugin came with its own php function to display the custom field called types_render_field. It displayed my images in order. To get fancybox working I had to do sort of a hack on the string. Here's the code:
$images = ( types_render_field( "image", array( 'size' => 'full', 'alt' => get_the_title(), 'title' => get_the_title() ) ) );
$imgArray = explode(">", $images);
foreach ( $imgArray as $value ) {
$pos1 = strpos($value, 'src="', 0)+5;
$pos2 = strpos($value, '" ', $pos1);
$link = substr($value, $pos1, $pos2 - $pos1);
echo ''.$value.">";
}
