WP_Query() load selected post
I need to load a selected post in a ajax function, I have some problems writing the appropriate query that calls the post i'm pointing

$pb_id = $_POST['post_id'];

'p' => $pb_id,

Homepage meta title and description not showing in search engines?
I have just launched a new website and have been having trouble locating it anywhere on search engines, so I decided to do a google search for **_"site:mysitename.com"_** to show all of the results from my website.
The homepage is the first page to be displayed, however, it is saying the meta title is a title of one of the blog posts on the website.
Once I click on the homepage link and view the source the meta title is set to **_Home | My Site Name_** as I have set it to. So my question is why in a search engine is the title of my homepage showing up as one of the blog posts names? | Google doesn't always show the meta descriptions and title's that you set. This is taken directly from Google's Search Console help pages.
> Google's generation of page titles and descriptions (or "snippets") is completely automated and takes into account both the content of a page as well as references to it that appear on the web. The goal of the snippet and title is to best represent and describe each result and explain how it relates to the user's query.

Bootstrap grid system is not working in my Wordpress theme

How are updates to the style.css file in child theme recognized?
When I update the _style.css_ in my active child theme, the changes are not immediately picked up.
I tried doing a `touch` on the file, but the results have been inconsistent. It worked once, but did not work the next time. The changes were recognized after waiting for some time (~15 minutes). I checked the file timestamps and they
Is there something else that I need to do to let WordPress know that the style.css file has been updated for the current theme? Is the browser's concept of time involved in the decision to include changes from the style.css file?

Custom post type based on existing one

Show recent products first but "sold out last" in query
I am using WooCommerce and would would like to show the "out of stock" products last in the query on the archive page. How can I do that?
Currently we are making the newest product show first with the following custom query:
add_action( 'pre_get_posts', 'mik_exclude_category' );
function mik_exclude_category( $query ) {
if ( $query->is_main_query() ) {
$query->set( 'orderby', 'date' );
$query->set( 'order', 'DESC' );
}
}
So, we would like to do both. Show the newest products first, but show "out of stock" products last no matter how new they are.
Sincerely, Mika | If we only have two stock statuses, namely `outofstock` and `instock`, we can very easily achieve sorting with `pre_get_posts`
add_action( 'pre_get_posts', function ( $q ) {
if ( !is_admin() // Target only front end
&& $q->is_main_query() // Only target the main query
&& $q->is_post_type_archive() // Change to suite your needs
) {
$q->set( 'meta_key', '_stock_status' );
$q->set( 'orderby', 'meta_value' );
$q->set( 'order', 'ASC' );

custom post type archive page url to point to Page permalink
I wish that my 'custom post type archive page' would point to Page.
The situations is as follows:
I have `Page` in Wordpress with permalink ` This page shows list of posts with custom post type = `vmgallery`. I have custom logic for this page that is working fine.

How to achieve this? | You have multiple options here.
**1\. Define post type archive slug on post type registration**
By setting `'has_archive' => 'galleries'` you can define custom post type archive slug. Check documentation. Then you can delete your page "galleries" then add & customize the `archive-post_type.php`
**2\. Disable default archive for post type**
Disable the archive by setting `'has_archive' => false` then keep the page for the post type archive.
**3\. Redirect archive requests to your page**
You can permanent redirect default archive request to your page.

wp_redirect( home_url( '/galleries/' ), 301 );

Wordpress Child Theme Template auth_redirect wrapper
I'm successfully utilizing a child theme in Wordpress. I would like to create a page template that simply forces login for any visits to the pages where this template is in use. (Simply need to add `<?php if (!is_user_logged_in()) { auth_redirect(); } ?>` to a separate template.) Copying the existing template down to the child theme makes updating tedious and prone to failure for such a simple call. However, I cannot find a way to create a new template that calls a parent template. I will admit that I may not be understanding an existing call, but I have been unable to see any way to do this.
Setting URL filters for every page is not a usable option. I'm also unable to use slugs, as they are already in use for another purpose. | I solved the issue at hand by creating a Custom Field of requires_login and setting it to "true", then adding the following code to functions.php:

auth_redirect();
}
}
add_action('template_redirect', 'require_login');

wp_category_checklist won't show up for non-admin users
I have a product registration page with a form in which I use `wp_category_checklist()` to make my users select categories. This works great only, I just today noticed that only admin's can use the checklist! **For normal users the whole category list doesn't even show up!** Is there any workaround for this? I've googled but couldn't find it.
What I mean with " _it doesn't show up_ " is that every element below the `wp_category_checklist` in the DOM gets deleted.

<body><? wp_category_checklist(); ?>
<div> one million div's here</div>
</body>
It won't show me anything on the page, the `<body>` would be blank. | If you want to use the wp_category_checklist on pages that also non-admin users access. You have to include the following php:

Random posts in WP_Query when searching by tag

'post_status' => 'publish',
'order_by' => 'date',
'order' => 'DESC',
'ignore_sticky_posts' => 1

How to check if "is single" page
I know – at first glance the problem may seem easy to solve – and I hope it is – I just can't figure out where/ how to check if I'm really on a single page, or just rendering a single page in the loop.
I basically need to alter the page title of CPT pages. This is what i have tried so far:
function event_page_title($title) {
global $post;
if ( ( 'event' == $post->post_type ) && ( is_singular() ) ) {
$title = "Title: " . $title;
return $title;
}
add_filter('the_title', 'event_page_title', 0);
Problem is: the title is also altered in listings (`WP_query`) – although not in archive pages. I hope somebody can point me some direction? Thank you! | You can use `is_singular()` with post types like this:
if( is_singular('event') ) {
// We are in single view of event post type
}
So, your code could be:
add_filter( 'the_title', 'event_page_title' );
function event_page_title( $title ) {
if ( is_singular( 'event' ) ) {
$title = "Title: " . $title;

WP_Query offset argument does not work

WP_Query( array(

'offset' => 20,
'cat' => 5,
) );
This query shows all posts without starting from the offset value. Whys is that? | The `offset` index for WP_Query generally works with pagination. When you set pagination to a `-1` the function assumes you're getting all posts and there will be no pagination or offset. So to counteract this you would set the `posts_per_page` to a high number like 999. Reading the Function Reference on WP_Query the pagination section says:
> `'posts_per_page'=>-1` to show all posts ( **the`'offset'` parameter is ignored with a -1 value**). Set the ‘paged’ parameter if pagination is off after using this parameter. | stackexchange-wordpress | {

Is accessing theme and using customizer GPL distribution?
I am theme developer and I want to make a "demo" website, where people to which I give password will have access to nearly all theme functions (except theme editor) -> they won't have full admin rights. They will use it only to evaluate theme. Problem is that, I don't want to them to have the right to a have copy -> to not distribute theme to them.
My question is whether using customizer and theme options counts as redistribution, therefore use of GPL which force me to give them the source code which I don't want to. | In my understanding (and I'm not a lawyer, etc etc), this would not count as distribution.
I make this distinction mainly based on the fact that a separate GPL-flavoured license actually exists where this _would_ count as distribution - the GNU Affero General Public License.
GitHub's choosealicense.com states:
> GNU AGPLv3 is distinguished from GNU GPLv3 in that hosted services using the code are considered distribution and trigger the copyleft requirements.
(<
Therefore, as long as you're using the GPL and not AGPL, I believe what you're doing wouldn't count as distribution.
Remember though that once you sell your theme under the GPL, the buyer can do whatever they like with it - including posting the source code online for free. | stackexchange-wordpress | {

ACF allow zero as a value
I would like to have 0 to 5, and "n/a" as possible values, however this code will output "n/a" when I want it to output a zero. How can I get it to output "0"?
("n/a" is the placeholder if no value is set.)
Difficulty: <?php if(get_field('difficulty')) { echo the_field('difficulty');} else { echo "n/a"; } ?> | In PHP, `0 == false == [] == '' == null`. A simple check to check if a variable or condition has a value will return `false` if the value is equal to 0.
For `0` to return true as a valid value, you would need to make use of strict comparison by using the identical ( _`===`_ ) operator. Just remember, if you use `===`, not only the value must match, but the type as well, otherwise the condition will return false. If your values are a string, you should use `'0'`, if they are integer values ( _which I doubt as custom field values are strings as single values_ ), you should use `0`.
You can do the following check
$difficulty = get_field( 'difficulty' );
if ( $difficulty // Check if we have a valid value
|| '0' === $difficulty // This assumes '0' to be string, if integer, change to 0
) {
$value = $difficulty;
} else {
$value = 'n/a';

Plugin upgrade failing during unzip
I am having an issue upgrading one particular plugin on a site of mine. All other plugins on this site upgrade without an issue. It is not a permissions issue as this has been checked multiple times and like I say all other plugins update perfectly.
The error occurs during the unzipping of the upgrade package. Specifically it occurs in the `_unzip_file_ziparchive` function.
The error is sometimes mkdir_failed_ziparchive (Could not create directory) and other times it is copy_failed_ziparchive (Could not copy file). The directory or file on which it fails varies.
It is not the first directory it tries to create or the first file it tries to copy. I have run the process with some logging code added and can see that it is able to create many directories/copy many files to the location in the wp-content/upgrade folder before throwing the error.
I am stumped as to what the cause could be and would appreciate any insights. | The name of the temporary file created by the `download_url` function is 118 characters long.
The length of this is causing the full path name of some files or directories created during the unzip process to be longer than the allowable length on Windows. Therefore an error is thrown and the plugin upgrade fails.

WP-all-import problems with large input file
I'm running development environment xampp (windows) and production server.
On the DEV virtual machine, everything works correctly, PROD server doesn't work:
* wp-all-import plugin
* large XML feed < (175 MB)
* login to wp wp-all-import -> new import -> from URL
* file correctly downloaded to server -> AJAX redirect to "xpath builder" -> xpath "/PRODUCT" AJAX returns only 15 results

* DEV machine imports all 82600 records correctly

WooCommerce pages accessible to logged in members only
I’m building a shop in WooCommerce and wish to restrict access & viewing of the shop to logged in members only.
I don’t mind having links to the shop visible (such as in the nav bar), as clicking the shop link, or trying to directly access a shop item would check if the user is logged in, and if not, then redirected to ‘My Account’ to create an account.
Any there any options available to me via plugins or the functions.php?

Change post title if post has specific category
Basically what I am trying to achieve is to have title changed of posts which are in category number 30.

function adddd($title) {
if(has_category('30',$post->ID)){
$title = 'Prefix '.$title;
}
return $title;
}
add_action('the_title','adddd');
The code works, but has one issue. When I am inside the post which has that category, title is being changed for all other pages (which are called through the_title) too.
How can I change the title only to post titles which has that category, no matter what page I am on? | `$post` is undefined in your filter. You need to explicitely invoke the `$post` global inside your filter function to have it available. You must remember that variables ( _even global variables_ ) outside a function will not be available inside a function, that is how PHP works.
You actually do not need to use the `$post` global, the post ID is passed by reference as second parameter to the `the_title` filter.
You can use the following:
add_action( 'the_title', 'adddd', 10, 2 );
function adddd( $title, $post_id )
{
if( has_category( 30, $post_id ) ) {
$title = 'Prefix ' . $title;
}
return $title;
}
If you need to target only the titles of posts in the main query/loop, you can wrap your contional in an extra `in_the_loop()` condition | stackexchange-wordpress | {

How to get the first image gallery of a product in woocommerce in a loop
I want to display a product with a product image and when visitor hovers over that image, it will change to the first image from the product gallery. I am using this code to display the image gallery, but it displays all the images from product gallery. I just want the 1 image.
<?php do_action( 'woocommerce_product_thumbnails' ); ?>
Anybody know how to resolve this problem? Really appreciate any ideas.
Regards | Along with the product thumbnail (I'm assuming you have this), what you need is a list (array) of the product images - WooCommerce has such methods, eg `$product->get_gallery_attachment_ids()`.
You can grab the first ID in the array and use it to fetch the single image using `wp_get_attachment_image()`, or `wp_get_attachment_url()`, etc., then use that as an alternate source for the main (thumbnail) image.
Incidentally, the `woocommerce_product_thumbnails` call is outputting markup that you probably don't want to use. You'll need to either discard this or unhook functions from it to get the output you want. | stackexchange-wordpress | {

Wordpress CPT slug and page slug conflicts
I have one page slug "new-site" also i have another custom post type with same slug "new-site" while i browse site < then it directally goes to archive page and show all the posts from CPT new site.
How can i solve if i open with this url to page < and < for cpt post detail.
Thanks | As you don't need the CPT archvie, the easiest way to use `example.com/new-site` to open a page, and `example.com/new-site/post-slug` to open single posts of "new-site" post type, is to declare `has_archive => false` when registering the CPT:
add_action( 'init', 'cyb_register_cpt' );
function cyb_register_cpt() {
$args = array(
// .....
'has_archive' => false
);

Can I use both a custom excerpt and a trimmed excerpt?
For each post, I use the custom excerpt field to write a custom excerpt (180 characters max) for each of my posts, which I use as the meta description of my post for SEO.
When I show a list of my posts (archive pages, categories etc.) this excerpt is displayed as "teaser text" for each of my posts. The problem is that this text is too short, as it is written for meta description purposes.
Would it be possible to have a longer excerpt showing in category and index pages, yet keep my custom excerpt as a meta description of each post?

Help with rewrite rules for two post types
I'm trying to setup two rewrite rules for two post types. Basically, the structure I want is this:
`site.com/app/course/xxxx/` => adds query_var _course_
`site.com/app/course/xxxx/theme/xxxx/` => adss query vars _course_ and _theme_

public function rewrite_rules(){
add_rewrite_tag( '%course%', '([^&]+)' );
add_rewrite_tag( '%theme%', '([^&]+)' );
add_rewrite_rule("^app/course/([^/]+)/?",'index.php?page_id=3400&course=matches[1]', 'top' );
add_rewrite_rule('^app/course/([^/]+)/theme/([^/]+)/?','index.php?page_id=3400&course=$matches[1]&theme=$matches[2]', 'top' );
}
If I add just the first rule, it works. If I only add the second rule, it works too. But, if I add both, only the first rule works. The second rule loads a valid page, but the _theme_ var is not set.
Am I doing something wrong? Any tips are welcome! | The first rule is capturing all requests. If you add a `$` anchor at the end of the rules, they'll behave as expected (you could also just switch the order of the rules so the more specific one "wins").

function remove_nada_theme_font_style() {
remove_action( 'wp_enqueue_scripts', 'nada_theme_styles' );
}
add_action( 'after_setup_theme', 'remove_nada_theme_font_style' );
Since the child theme is loaded before the parent theme, you can't simply remove the action. because the add_action calls in the parent theme will simply overwrite your requests. You have to wrap it into the after_setup_theme hook. This hook will fire after the child and parent theme is loaded. So all removing filters and actions from the parent theme should go there.

Correct use of get_the_terms()
I need to print all terms associated to a custom post type post. In the post template I wrote that code:
<?php foreach (get_the_terms(the_ID(), 'taxonomy') as $cat) : ?>
<?php echo $cat->name; ?>
<?php endforeach; ?>
The loop works correctly, but before the list also the id was printed. Like:
37
taxonomy01
taxonomy02
taxonomy03
What is wrong? | `the_ID()` print the post ID. You need to use the `get_the_ID()` which return the post ID.
Example:
foreach (get_the_terms(get_the_ID(), 'taxonomy') as $cat) {
echo $cat->name;
}
Always remember the naming convention of WordPress for template tags. `the` which mean to print `get` which mean to return in most of the cases. | stackexchange-wordpress | {

How to use WP Theme Option: Custom_Backgrounds on specific element?
I want to use the WP Theme option Custom_Backgrounds on a specific div.
By default it adds it to the body and I dont see a way of changing this.
Does anyone know how? | If your theme uses in-built `custom-background` callback then you can overwrite `add_theme_support` in your child theme. Yo do not need to use `remove_theme_support`.
First add `custom-background` support with your callback function.
$defaults_args = array(
'wp-head-callback' => 'my_custom_background_cb',
);
add_theme_support( 'custom-background', $defaults_args );
In callback function specify `div` CSS class or ID

$bg_image = get_background_image();
if ( empty( $bg_image ) ) {
return;
} else { ?>
<style type="text/css">
.your-div-class {
background: url('<?php echo $bg_image; ?>') no-repeat;
}
</style><?php
}

Logging in takes a few refreshes to show you are logged in, is this a cache issue?

How to change _wp_attachment_metadata specific value in SQL?
i had to resize a lot of existing images in my upload folder (around 1k). After reuploading them, Wordpress of course, doesn't recognize the new dimensions. My approach was to just change the size in the _post_meta table. But this looks like this:
a:6{s:5:"width";s:3:"330";s:6:"height";s:4:"1067";s:14:"hwstring_small";s:22:"height='96' width='29'";s:4:"file";s:22:"2012/03/2-IMG_1540.png";s:5:"sizes";a:3:{s:9:"thumbnail";a:3:{s:4:"file";s:21:"2-IMG_1540-56x183.png"; ...
All I need to change is the "width" value of the first entry from "330" to sth. else. Although it looks like a dictionary to me I do not find a way to get access to that value in SQL.
The wp_update_attachment_metadata reference states that all data must be given as existing data will be wiped. That's the reason why I thought it would be easier to do it in SQL. | You could do this via PHP instead of SQL, just get the existing metadata and change what you need to, it will handle the serializing for you:
$newwidth = '250'; // or whatever it is
$attachments = get_posts(array('post_type'=>'attachment'));
foreach ($attachments as $attachment) {
$id = $attachment->ID;
$metadata = wp_get_attachment_metadata($id);
$metadata['width'] = $newwidth;
wp_update_attachment_metadata($id,$metadata);

Correct use of curly braces vs alternative synax

Is there a good reason why WordPress uses these instead of curly braces for block statements? | As in many things wordpress, inertia has a lot to do with why things are done in specific way. Early core themes were written using those constructs and later developers copied them because they either did not know better or thought there was some non obvious reason to prefer them.
As @Howdy_McGee said, it is just a style preference but I would avoid the `endif`, `endwhile` as curly braces are standard block delimiters across many languages and therefor are in general easier to read even if we will ignore the benefit of syntax highlighting and block collapsing in general editors. | stackexchange-wordpress | {

This means my custom fields are below the default fields.
I have 'comment-title' and 'rating'fields that I need above the comment field.
Is there another Hook I could use? If not should I resort to editing a comment comments.php? | Sure, you could use the `comment_form_field_comment` filter to inject content (extra fields or whatever) above the comment field:

$new_field = '<p class="comment-form-extra"><label for="extra">Extra Field</label> <input id="extra" name="extra" type="text" value="" size="30" aria-required="true" required="required"></p>';
$field = $new_field . $field;
return $field;
}
add_filter( 'comment_form_field_comment', 'comment_form_field_comment_add_field' );
You could also switch that around to put the new/extra field below the comment field:
$field = $field . $new_field;

"Add media" dialog is not showing any images

Best way to save postmeta
Just wondering what the best way to save postmeta is.
I don't want empty postmeta values clogging up the database.
I had already been saving postmeta in my plugin, which was adding empty values, so I'd like to clean those up as people re-save their posts.

update_post_meta( $post_id, '_my_meta_key', $_POST[ '_my_meta_key' ] );
} else {
delete_post_meta( $post_id, '_my_meta_key' );
} | Your approach is good, you should run a basic check against the data tough. Otherwise you might get an array or a serialized object … which might lead to unexpected consequences (including security issues!) when you or someone else is trying to print the values.
Maybe something like this is easier:
$key = '_my_meta_key';
$value = filter_input( INPUT_POST, $key, FILTER_SANITIZE_STRING );
if ( $value )
update_post_meta( $post_id, $key, $value );
else
delete_post_meta( $post_id, $key );
Note that you should avoid writing the key string more than once. If you ever want to change its name, you should have as few places to search for it as possible. Ideally, just one in your whole code base. | stackexchange-wordpress | {

Is it possible to slow down site with a bulky child theme?
I am creating a child theme for my theme and as I go through all the modifications that I want, I am almost overriding all the templates and adding a functions to the theme and had to dequeue some styles and scripts to be able to override it.
While I know overriding the templates has no effect on the speed, because the parent templates dont get loaded when there is a child version, but I don't know how much (if any) resources the loading of unused functions in the parent take up or if dequeing many styles and scripts take up resources.
So the question is if there comes a point sometime in child theme development when it is better to take over the theme development and just integrate the changes and use without a child theme? Or is it not worth thinking about there is probably little to no difference between using a child theme with a lot of overrides to using a modified parent theme? | Yes. There is a definitely a point where you just want to create a new theme.
Unless you are writing more than a thousand lines of code, I would not be worried about performance problems with your child theme, if the parent theme is well-constructed.
Adding conditional statements to test if scripts and styles are needed for certain pages will improve site response, not reduce it. The amount of processing time for the server to test three PHP `if` statements is negligible. | stackexchange-wordpress | {

Check if Page Slug Exists, then display that Page's Title

so when i put this code on the page to lookup the slug:
<?php if (the_slug_exists('page-name')) {
echo '$post_title';
} ?>
everything is perfect other than the fact I need the function to output the title as well as lookup the slug, hopefully that makes more sense. | looking at MySQL query in the function it becomes clear that though it matches the post_name and returns true or false. What you want to find is, if a page exists by its slug. So, in that case, the function you have chosen is wrong.
To get the page by title you can simply use:
$page = get_page_by_title( 'Sample Page' );
echo $page->title
Just in case if you want to get page by slug you can use following code:
function get_page_title_for_slug($page_slug) {
$page = get_page_by_path( $page_slug , OBJECT );
if ( isset($page) )
return $page->post_title;
else
return "Match not found";

`add_filter('eventon_eventCard_evotx', array($this, 'frontend_box'), 10, 2);`
and the function is
`function frontend_box($object, $helpers){
.....stuff that stays....
include(name-of-file);
.....more stuff that stays.....
}`
I would appreciate any help you guys could offer or point me towards | It is not (easily) possible to interfere with PHP `include`.
What you can do in general is:
1. Fork a function (create your own copy under different name)
2. `remove_filter()` the original function
3. `add_filter()` of your function in its place
However that can get impractical very fast.
If the file being loaded makes sense to be customizable the first thing I would do is suggest to plugin developers to make it _easily_ so, introducing a specific filter for it or otherwise. | stackexchange-wordpress | {

Best | If you are looking at core source then what you see it use is Underscore.js template. WordPress has slightly modified the syntax of templates themselves, but it's the library it uses.
As far as I remember it was added when some parts of admin interface became more _rich_ and interactive, starting with media management. Unfortunately at the time (and still since) this part of WordPress is grossly underdocumented. As far as I am aware there is simply _none_ official documentation for it.

How to set wp_options in functions.php for removeing the Default Front Page
I want to disable the default front page as I want to show always the first listed page in the frontend. Therefor I disable the Static Front Page.
But I have also to set in **wp_options** the variables **show_on_front** and **page_on_front** to remove the old default Front Page.
I can manipulate the variables in the DB:
UPDATE wp_options SET option_value = 'page' WHERE option_name = 'show_on_front';
UPDATE wp_options SET option_value = '0' WHERE option_name = 'page_on_front';
How can I set this variables fix in my `functions.php`? Or is that the wrong approach? | You can use following:
update_option( 'show_on_front', 'page' );

Display post from a date range from custom field
I currently have a custom post type that has two major custom fields that are need for the query.
The 'score_time' field stores time of a score. Example: 12:20 The 'score_date' stores the date the game took place. Example: 01/22/2016
I need query to display post from a specified date range and they are ordered by the 'score_time' field value
Right now I don't have the date range working, but here is the code i have right now.
$args = array(
'post_type' => 'score_post_type',
'posts_per_page' => 5,
'meta_key' => 'score_time',
'orderby' => 'meta_value',
'order' => 'ASC',
); | The magic parameter ist described at WP_Query under: **Custom Field Parameters**
You need to add a `meta_query` array to your `$args` where you define your range.
In your case the code could look like this:
$range = array(
'2015-05-01',
'2015-05-31',
);
$args = array(
'post_type' => 'score_post_type',
'posts_per_page' => 5,
'meta_key' => 'score_time',
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_query' => array(
array(
'key' => 'score_date',
'value' => $range,
'compare' => 'BETWEEN',
'type' => 'date',
)
),
);
**NOTE:** Make sure that your date and time values are valid SQL date/time values. Your provided format MM/DD/YYYY is bad for sorting and querying. Better: YYYY-MM-DD. | stackexchange-wordpress | {

Modify Maximum upload file size text

if ( ( $size > $limit ) && ($is_image !== false) ) {
$file['error'] = 'Image files must be smaller than '.$limit.'KB';
}
return $file;
}

I assume it pulls this value from the servers PHP config, is there a way to modify this text? | This text is coming from `wp-admin/includes/media.php#L1946`

<nav class="top-nav">
<a href="">О студии</a>
<a href="pricing.html">Стоимость работ</a>
<a href="">Галерея работ</a>
<a href="">Важное о наращивании</a>
</nav> | First step is to register the name (or names) for your menus. In your example, top-nav seems appropriate.
function vd_register_menu() {
register_nav_menu('top-nav',__( 'Top Nav Menu' ));
}

Does something like is_rest() exist
I am starting a bit with the REST API. If I am not completly mislead, the `init` action hook is also executed when its a REST API request. Now, I want to execute some code only, when it is not a REST API request.
So I was looking for a command like `is_rest()` in order to do something like
<?php
if( ! is_rest() ) echo 'no-rest-request';

add_action( 'parse_request', 'rest_api_loaded' );

What does this if-statement do?: if($pages=' ') {}
This is an excerpt from a tutorial on how to create pagination for an blogpost overview page.
What does the first part `if($pages == ''` _exactly_ do?
> **_Quote from tutorial:_** Now we know which page we are currently viewing, but we also need to know how many pages we got. We are still asuming that we are not using a custom loop and that the $pages variable (dont mix up with $paged) was not set when we called the script. If thats the case we can once again make use of a global variable to get that number:
if($pages == '')
{
global $wp_query;
$pages = $wp_query->max_num_pages;
if(!$pages)
{
$pages = 1;
}
} | `$pages` is an optional parameter. If not set, `$pages` will equal an empty string. So `if($pages == '')` checks to see if that parameter has been set.
In this call, the parameter has not been set: `kriesi_pagination();` In this call, the parameter _has_ been set: `kriesi_pagination(5);`

get_term_by "name" not working with & in name
I want to get category id by name so I am using get_term_by
This is working fine when name is simple but when '&' is coming in term name it is not fetching category id.
e.g I have a term named "Website Development & Designing" under **skills** taxonomy and I am using following query to get its term id.
$value = "Website Development & Designing"
get_term_by('name',$value,'skills');
but it does not return term object :( | The characters <, >, &, " and ' (less than, greater than, ampersand, double quote and single quote) are enconded in term names. & becomes `&`. This is done by passing the term object to `sanitize_term()` function which applies several filters. By default WordPress applies theses filters: `sanitize_text_field()`, `wp_filter_kses()` and `_wp_specialchars()` (see `wp-includes/default-filters.php`), this last function encondes <, >, &, " and '.
So, you need to do:
`$value = "Website Development & Designing" get_term_by('name',$value,'skills');`
Or, for unknown values:
`get_term_by( 'name', esc_attr( $value ), 'skills');`
NOTE: use `esc_attr()`, not `_wp_specialchars()` directly because `_wp_specialchars()` is marked as private function and it is not intended for use by plugin or theme developers. | stackexchange-wordpress | {

Display taxonomy term only if there's a value
I have a post type which I want to add some taxonomy values (tags)
Example Post Type One
1. **City** : London, Paris
2. **Color** : Red, Yellow
3. **Language** :
In the example above, Language doesn't have any value, therefore, I want to hide it.
I have this code:
<?php
$lang= get_terms( 'lang' );
if ( !empty( $lang)) {
echo '<li><strong>Language:</strong>';
the_terms( $post->ID, 'lang', ' ', ', ' );
echo '</li>';
}
?>
But **Language** will still appear even though I don't add any tags on it. | `get_terms()` return all the terms in the taxonomy regardless of the current post. So if current post does not have **lang** terms still this condition `if ( !empty( $lang))` will be `true` thus it will display the text **Language**.
Use `get_the_term_list` instead of `the_terms` which return the terms list instead of printing, so output can be used for both purpose.
Example:-
$lang = get_the_term_list( get_the_ID(), 'lang', ' ', ', ' );
if ( !empty( $lang)) {
echo '<li><strong>Language:</strong>' . $lang . '</li>';
}

How to change Woocommerce breadcrumbs content?
I want to customize the breadcrumbs directly from PHP. Some of the pages are generated dynamically and do not exist in the database, therefore i must automatically put them in the breadcrumbs with some sort of PHP script.
I don't need to change default stuff, like homepage url, separators, etc...but i actually need to manually put some pages in the breadcrumbs. I was trying with some filterings and some hooks.
I've read the documentation but it just explains how to change default stuff.
How can i change the actual content of the breadcrumbs?
I tried this:
add_filter( 'woocommerce_breadcrumb', 'change_breadcrumb' );
function change_breadcrumb( $defaults ) {
// Change the breadcrumb home text from 'Home' to 'Appartment'
//do something
return $defaults;
}
But the `//do something` never executes. It's like if that filter never gets called | That is due to the fact, that your filter `woocommerce_breadcrumb` doesn't even exist.
This filter here works and pulls out all the elements, that are currently in the breadcrumb (as an array):
add_filter( 'woocommerce_get_breadcrumb', 'change_breadcrumb' );
function change_breadcrumb( $crumbs ) {
var_dump( $crumbs );
return $crumbs;
}
And this filter pulls out the `main term` (as an object).
add_filter( 'woocommerce_breadcrumb_main_term', 'change_breadcrumb' );
function change_breadcrumb( $main_term ) {
var_dump( $main_term );
return $main_term;
}
The 'main term' is just the first element that is returned by this function (reference):
$terms = wc_get_product_terms( $post->ID, 'product_cat', array( 'orderby' => 'parent', 'order' => 'DESC' ) )

// do whatever
}
But while debugging the post object I've seen that there is no trace of it.
Can someone help me understand the reason why this happens? | The reason you don't see it if you dump object is because it's not _actual_ object property.
`WP_Post` implements magical `__get()` method for `ancestors` and several more keys like that. When you access `$post->ancestors()` what you actually get is not some value from the object, but return of `get_post_ancestors()` function executed on it.
