Post URL duplication adds numerical value
I thought that belonging to these different categories url naming posts the same would be treated as distinct.
Categories:
* Home
* Hotel
Posts:
* street
* street
URL generated:
1. www.my.com.br/casa/street-a
2. www.my.com.br/hotel/street-a-2
> I wonder how to solve this, I imagine that it affects> SEO <.
What is the solution to set that House and Hotel BELONG the same street to avoid being added this numerical value 2? | Posts have a slug (that's the last part of the URL), and it must be distinct, even if posts are in different categories.
If your only worry is SEO, don't worry. Google sees the URLs as distinct, and Google is used to dealing with URLs that have a suffix on them, and has no problems with it. The keywords in the URL are still the same and have the same value.
If you still want to change this, you could manually change the slug when you create the post, or you could hook into save_post and change the slug to be street-casa. But there is no need. | stackexchange-wordpress | {

Override plugin localization
Is it possible to override the localization files provided (or not provided) by a 3rd party plugin? A plugin that I'm using now doesn't have any language files but I want to avoid having a future update to the plugin overwrite the translation files that I've created. | From what you are saying you have translated your plugin and now you want to be sure the future update won' be overwritten. So to avoid that happening you can always put your po/mo translation files (if provided) in global languages folder that is located on your server in wp-content/languages/plugins folder.
If plugin have language file name for example someplugin.pot, from there you can generate someplugin-en_US.po and someplugin-en_US.mo files and put them in folder I mentioned before. Note that I put language code en_US just as an example you will add your language code.
Or you can just not update the plugin (but not recommended). There is also a plugin that disables plugin from auto update here.
Also for all kind of translations I would recommend using you LOCO TRANSLATE which you can use and automatically put your po/mo files generated from plugin .pot to global languages folder.
I hope this helps.

After plugin activation hook
Does it **OK** , to send email (to me) after user activate my plugin?
Does it a right way to do that (< with hook?
thanks | In the context of official plugin repository this is very explicitly forbidden by the guidelines (emphasis mine):
> 7\. No "phoning home" without user's informed consent. This seemingly simple rule actually covers several different aspects:
>
> * No unauthorized collection of user data. **For example, sending the admin's email address back to your own servers without permission of the user is not allowed** ; but asking the user for an email address and collecting if they choose to submit it is fine.

'taxonomy' => 'meal',
'field' => 'slug',
'terms' => 'breakfast'

Users are redirected to homepage instead of wp-admin
After migrating my wordpress site users **who are not Admins** are redirected to the site's **homepage after login**. On the old site they were redirected on wp-admin. The Administrator is redirected to wp_admin as it should.
I want the users to be redirected to `wp-admin` after login.
I changed siteurl from the database (`wp_options`), also added this filter in my `functions.php`:
function my_login_redirect( $redirect_to, $request, $user ) {
return admin_url();
}
add_filter( 'login_redirect', 'my_login_redirect', 10, 3 );
Any help please? Thank you and Happy Easter! | Yeeey, I figured it out! Actually my theme had a redirect like this one in `functions.php`:
// Block Access to /wp-admin for non admins.
function custom_blockusers_init() {
if ( is_user_logged_in() && is_admin() && !current_user_can( 'administrator' ) ) {
wp_redirect( home_url() );
exit;
}
}
add_action( 'init', 'custom_blockusers_init' ); // Hook into 'init'

How do I routinely extract the thumbnail of the most recent post?
I would like to write a PHP snippet that can communicate with Wordpress.
When a new post is published, a file today.jpg will be generated from the thumbnail url (a custom field) of the most recent post.
Or I can schedule a cronjob to execute daily for this action.
How can I implement this function?
My idea is to do it outside of functions.php so that it won't get executed all the time, while a scheduled update for today.jpg seems more resource friendly.
Any pointer is appreciated. | No need for a routine here - use the WordPress hook system to "attach" a function that will run when a post is published:
//
function wpse_225371_post_published( $post_id, $post ) {
// Do your thang

Is it possible to place custom post type files inside a folder in theme directory?
I have created a custom post type called `customtype`. From my understanding the template file for it would be `single-customtype.php` which is placed inside `wp-content/themes/mytheme`.
Can I place the `single-customtype.php` file inside a custom folder in the theme directory? It's not critical but would help with theme files organization.
This is what I want to achieve: `wp-content/themes/mytheme/customtype/single-customtype.php` | You may want to look at the TwentySixteen theme, which does it this way:
In `single.php`:
`get_template_part( 'template-parts/content', 'single' );`
Several templates are grouped in the 'template-parts' folder. You could use a similar logic for your custom post type.

Cannot Find Hook that is changing the_content()
I am working with a wordpress theme that is using Foundationpress as it's starter theme. When I use `the_content()` all `img` tags have there css class replaced with `image`. This is overwriting the ability for the editors to use there own classes.
While debugging if I `die(get_the_content())` I see the original classes. I have been going through the entire project trying to find where that logic could be overwriting these classes. Has anyone seen this before ?
So far i have checked:
1. Functions.php
2. All javascript
3. Library directory that comes with foundationpress.
Anywhere I could be overlooking? | It's unusual for `the_content` to be rewriting image classes like this; it sounds like it could be a plugin (or theme function) which is doing this. Have you disabled all plugins just to check?
Having said that, most of the functions in core that hook into `the_content` are located in `wp-includes/default-filters.php` (apart from the oembed functions).
You can remove any of them by adding the following to your theme's `functions.php`, eg. to remove the `wpautop` function:
remove_filter("the_content", "wpautop");
However none of these should be messing with these classes. The `wp_make_content_images_responsive` function _will_ be messing with image tags, but it should only be checking the classes, not changing them, which is why it sounds like these changes could be happening in a plugin. | stackexchange-wordpress | {

Best db table structure for users with many records
I want to allow users to have 1000+ records in my WordPress system.
I was wondering is it best to have just one table for all users and their records or one table per user?
Keep in mind that I could have 1000 users.
A user columns for records would look like:
User_client_name | User_id | User_post_id | etc...
Each user might have 1000+ records in the database of their contacts. If I put all users in one table, I would have to show each of my users their records separated by User_id.
I was wondering is it better to create a new table per new user I signup for? Or stick to one table of users and their records? | Personaly I would go with one table for all users. Having more tables with the same columns seems like a strange idea to me. The database will be a complete mess after you gwt more users.
Make sure that the `user_id` is an index for the table and all your select/update/delete will be fine. The insert might have a very short but unsignificant delay after the table gets bigger, but I guess this might not be the most used opperation. | stackexchange-wordpress | {

Replace content via rest api only?

Add post/page ID to inserted links within the_content
Within the main content editor of posts and pages, we can insert multiple links to other posts/pages:
<a href=" World</a>
What I am trying to do is get Wordpress to automatically add the ID of, in this case, the Hello World post to the link. To try and clearly explain what I'm wanting, imagine I'm writing a new blog post and I put a link within the new blog post to my existing Hello World post.
<a id="4" href=" World</a>
Where in the above example our Hello World post has the ID of 4. I have been studying this answer to a different question but I haven't quite figured out how to get the ID of the post/page I am linking to and add it to the anchor element. Incase we have more than one link pointing to the same post/page it might be safer to use the rel attribute instead:
<a href=" rel="4">Hello World</a> | This is the solution I arrived at with thanks to the pointer from @bravokeyl
So, to be clear **it does not add the ID's to links** but by using the link slug I'm able to get the ID which is a solution for what I need. I'm using JS to pass the URL into this function and then stripping it down to the slug only which is used within `get_page_by_path` which then returns the ID for that post.
It's part of what I'm working on to build an Ajax powered theme. This approach also solves the issue of having multiple links with the same ID's.
function local_post_init() {
/** Get post ID from slug **/
$page_slug = $_POST['id'];
$page_data = get_page_by_path(basename( untrailingslashit( $page_slug ) ) , OBJECT, 'post');
$page_id = $page_data->ID;
/** $page_id holds our ID which we then use in our query */
$args = array( 'p' => $page_id );

What goes into wp_postmeta and why?
we are using WordPress in a site that has Places and eventsOn running, however we notice that sometimes the newly inserted place data goes into the wp_postmeta table others it doesn't... Searched for more information about this table schema and no result, can anyone shed a light on this and give me a better insight ?
Thanks, | Like several other tables it is just matching a key to value, when is this specific case they key is composed of the post id number and a string.
It is usually used to store additional information about the post that is not part of the content. In you case probably the place location or event time.
The reason to do such a thing, instead of just inserting it in the content, is to be able to run DB queries based on those values, for example find all posts that are related to event that happen at Christmas at NYC. This is something that is much harder to do when the information is in a free textual format as part of the text.

SELECT * FROM `wp_postmeta`
WHERE `meta_key` LIKE '%sku%' | I haven't tested this, but this should give you the count of skus for each post_id:
SELECT post_id, COUNT(`post_id`) AS sku_count FROM `wp_postmeta`
WHERE `meta_key` LIKE '%sku%'

To have it return only rows where the count is greater than one is trickier. Off the top of my head I'd probably use the above as a subquery:
SELECT * from (< insert the above query >) AS counts where counts.sku_count > 1

wpdb query on custom table not working

The following jQuery code works as expected, in that it inserts the specified html after the closing tag.
$( "html" ).append( "<div id='bf_rsvp_note_display'></div>" );
However, that's a clunky place to insert it. Ideally, I'd like to append it to , but using any other element stops it working.
$( "body" ).append( "<div id='bf_rsvp_note_display'></div>" );
and
$( ".exampleclass" ).append( "<div id='bf_rsvp_note_display'></div>" );
both do nothing - no errors, no anything.
Why is this? | These three lines work as expected , There is a problem maybe with other code before these lines that prevent the execution of your script;

Get all terms assigned to a post from different taxonomies
There are different taxonomies. I have assigned different tags from these taxonomies to different posts. Can anyone help me to get all the terms which are assigned to a post. (Different terms from different taxonomies are assigned to a post) | WordPress tracks which object types taxonomy applies to. This can be established on taxonomy registration or at some point after, so you shouldn't be trying to do this too early.
The approach would be to retrieve the list of taxonomies for the native `post` type and use it with lower level function, which supports multiple taxonomies:
$terms = wp_get_object_terms( $post_id, get_object_taxonomies('post') );
Of course if you interested in a list of _specific_ taxonomies you can just hardcode that as input. | stackexchange-wordpress | {

Option for pages order in backend
Can someone tell me what is this ordering in pages list in backend and how does it affect anything? Searching for wordpress pages order doesn't give me meaningfull results
`.
By default, this will output all of your pages firstly by their order, then by their title if the orders match.
This makes it simple to avoid the extra step entirely of configuring a menu, which is great for small sites - while still having the ability to get things in the right order.
Even on a site with menus defined, it can be nice to have the pages in the order one would expect to find them in, to make management easier. eg. I usually give the home page an order of -100 so it always appears at the top, and a Contact Page an order of 900 so it usually appears at the bottom. | stackexchange-wordpress | {

Custom script file enqueue has "?ver=4.5.1" when loading and doesn't update

Pass a parameter to a menu walker
Is there any way to pass a parameter to a menu walker? I'm trying to write a BEM-style walker, and I'd like to be able to pass a class to apply to the menu links via the walker. Something like:

"container" => false,
"depth" => 3,
"items_wrap" => "%3\$s",
"theme_location" => "primary",
"walker" => new BEMwalker("mobile"),
));
?> | As @toscho said, you can call the walker class with parameters as you did:
new BEMwalker( 'mobile' )
The constructor of `BEMwalker` will take the arguments (like any other function or method in PHP) so you can access the parameter(s) via `$this`:
class BEMwalker extends Walker_Nav_Menu {
private $classes;
public function __construct( $classes = '' ) {
$this->classes = $classes;
}
public function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {
$output .= sprintf( "<li class=\"%s\"><a href=\"%s\">%s</a></li>",
$this->classes,
$item->url,
$item->title
);
}

Problem with loading images from child theme CSS file with relevant path
I am getting an issue with loading relevant images within CSS file from a child theme directory. I placed -

background-image: url(/wp-content/themes/child-theme-name/images/some-image.png);

background-image: url(images/some-image.png);

Surviving Wordpress and plugin updates
In the phase of developing a new wordpress-based site, I'm evaluating also future pitfalls such as upgrades. Unfortunately, there's no guarantee that a third party plugin will not be discontinued. But that's how it works! There are two possible options:
1) Develop a tight robust site, with no future updates, and cross your fingers (hackers)
2) struggle to keep updated the site, and cross your fingers (what if plugin support is dropped?)
Is there a third option? | 3) Relax. You will have to update WP core anyway, so some work is inevitable. If a plugin is discontinued there usually will be an alternative. The most important thing is not to use plugins that require shortcodes in individual posts, because if these are discontinued that will really break your site.
Apart from plugins you will also have to worry about your theme, which may use functions that will be deprecated in future version of WP core. | stackexchange-wordpress | {

Special characters in tag get removed for comparison on save
Is there a list of characters, that are not allowed / are allowed in Tags? Or are there some more complex rules?
I first ran into the issue, that some tags are ok with a `*`-prefix, like: `*BLA-BL-BLA` but others are not `*BLA-BL-BLA blah`.
But after doing more testing, i found out, that i can not add a tag like `+BLA-BL-BLA blah` after `*BLA-BL-BLA blah`. The other way round also does not work.
It seems like the special chars get removed before a comparison and then the string matches an existing tag... | Basically, when you add a new term, WordPress will use `term_exists()` to validate term before add it to database.
1. `term_exists()` uses `sanitize_title()` which uses `remove_accents()` and `sanitize_title_with_dashes()` to sanitize term.
2. `remove_accents()` will converts all accent characters to ASCII characters and `sanitize_title_with_dashes()` will limits the output to alphanumeric characters, underscore (_) and dash (-), whitespaces will be converted to dashes, uppercase characters will be converted to lowercase characters.
3. WordPress also doesn't allow to create terms which have the same term slug at the same level of a taxonomy hierarchy.
**So, every characters which don't output the same term slug at the same level of a taxonomy hierarchy after passed through`sanitize_title()` function are allowed characters.** | stackexchange-wordpress | {

how to merge a WPQuery array with a PHP array and use the Loop to Output the result
I have a mostly normal `WP_Query` (getting 3 post types) for use on a Blog page. This works great.

I would like to Merge these arrays and use the WP Loop to output. seems like a stretch but figured I would ask. | Technically you _can_ merge things into loop, by manipulating its `posts` field (such as `$wp_query->posts` for main query). WP has it in `public` for visibility and access, as it tends to.

Detect if WP is running under WP-CLI
I use the wonderful WP-CLI tool. Due to dependence on Apache environment variables for a specific use case, I need to enable a bit of code to run only when running under WP-CLI. **How can I detect if WP is running under WP-CLI?**
In this specific case I _could_ check for the presence of the Apache environment variables in question. However, I would like to know the more general, canonical method to check. Thank you. | Within the `php/wp-cli.php` we find these lines:
// Can be used by plugins/themes to check if WP-CLI is running or not
define( 'WP_CLI', true );
define( 'WP_CLI_VERSION', trim( file_get_contents( WP_CLI_ROOT . '/VERSION' ) ) );
define( 'WP_CLI_START_MICROTIME', microtime( true ) );
so you could check if `WP_CLI` or `WP_CLI_VERSION` are defined. | stackexchange-wordpress | {

Can't run database query
I am writing a function to query some information from a custom table in the database. It seems that I am unable to query the database on the field I need.

global $wpdb;
$details = $wpdb->get_results("SELECT * FROM " . $wpdb->prefix . "ch_guests WHERE key = '" . $id . "'", ARRAY_A);
return $details;
}
$id is currently '001'. If I search on any other field in the table, I get the expected results, but on this field nothing is returned.
If I run exactly the same query in phpMyAdmin, it works fine. | Here issue with the column name. You are using column **key** in the query which is the default keyword/index in mysql.
For resolving this kind of issue just use the "Grave accent(`)' symbol in the query for the column name, No need to change the column name. So in your case the right query is
$details = $wpdb->get_results("SELECT * FROM " . $wpdb->prefix . "ch_guests WHERE `key` = '" . $id . "'", ARRAY_A);

Show modified time if post is actually modified
I want to display post updated time only if post is modified, I am using function `the_modified_time()` . So I just read about that there is if statement that can be used to check if post is even modified that looks like this:
if (get_the_modified_time() != get_the_time())
So I put this in my template where the time itself is being displayed so it looks like this now:
if (get_the_modified_time() != get_the_time()){
echo 'Last updated:' . the_modified_time();
}
And it is not showing at all. So obviously I am missing something here. | Loosely what you have should work already. However few things are off.
1. Calling these function without time format will produce values like `1:36 pm` (depending on your site's settings), which are not exactly comparable.
2. Post modified time can be _less_ than published in some cases, like scheduled posts.
So I would write it along the lines of:
if ( get_the_modified_time( 'U' ) > get_the_time( 'U' ) ) {
echo 'Last updated:' . get_the_modified_time();
}
`U` format stands for a numeric Unix timestamp, which is comparison–friendly. | stackexchange-wordpress | {

Could not insert term into the database
I've spent a fair while reading about the **"Could not insert term into the database"** error, but the fixes I have read (changing theme, fresh WP install, disable plugins) simply are not working.
I tried a force DB upgrade, still no joy.
Looking at `wp_terms` there's a category with `term_id` of 0. This is mighty strange and if I delete it, I'm then able to add a category via wp-admin. However, subsequent categories then fail with the **"Could not insert term into the database"** message and re-checking `wp_terms` shows the freshly added category as id 0! This seems to suggest WP is assigning the cat a `term_id` of 0 every time.
Has anyone seen this? Any ideas on a fix? The database in question is pretty huge, so a rebuild would not be a pretty thing. | OK. There where multiple issues here;
`wp_terms`, `wp_termmeta` and `wp_term_taxonomy` all had their ID's set not to `AUTO_INCREMENT`.

How to limit number of images being printer out in "Set Featured Image" pop up?
I have wordpress web site which contains over 150 000 images and when you click on "Set Featured Image" whole server slows down. Another thing is that it take a really long time to load images.
Is there any filter/action/hook to add pager or to just show last 10 images.
Another question is how to optimize whole thing (maybe images sort by subfolders with some plugin) so it can work | ### Update 1:
After dived into core AJAX call, this filter will only happen on `post.php` page:
add_filter('ajax_query_attachments_args', function($query){
if ( isset($_POST['post_id']) && !empty($_POST['post_id']) ) {
$query['posts_per_page'] = 10; // output 10 images only.
}
return $query;
});

1. You can use `ajax_query_attachments_args` filter:
add_filter('ajax_query_attachments_args', function($query){
$query['posts_per_page'] = 10; // output 10 images only.
return $query;
});
2. Because of querying attachments happens in core and using AJAX, I don't think we can optimize the whole thing. | stackexchange-wordpress | {

How do I remove the product thumbnail link from a specific div in Woocommerce?
I have a section on my front page that displays the top 4 most popular products from my Woocommerce shop. I is located within a div as such:
<div id="trending">
<p class="trending-title">Trending Products</p>
<?php echo do_shortcode('[best_selling_products per_page="4"]'); ?>
</div>
I want to remove the fact that the thumbnail image is clickable. I don't mean removing the 'add to basket' button but the thumbnail image is clickable and takes you to the individual product page. I initially though to edit the product-image.php file but I don't want to affect this feature across the entire site just in that div 'trending'. Does anyone know of how I can accomplish this? Thank you in advance for any answers and suggestions! | Yes you can for example target the link itself inside the trending id with CSS and remove the action with CSS itself, in your place it would be something like this:
#trending > li.product > a {
pointer-events: none;
cursor: default;
}
Note that this is CSS scheme, not exact CSS, that deppends on classes you have (I would be more specific if you provided link). But the point is you are targeting `<li>` inside `#trending` id and link inside `<li>` itself and you are disabling any events, so that will do the job.

Change users.php WP_User_Query

if( is_admin() && 'users' == $screen->base ){
$query->set( 'role', 'Subscriber' );

on line 3920 | `setup_postdata()`requires a post object such what you would get by using the `global $post`. You are using a custom field, presumably from ACF, and calling it $post. The problem is that it is not an object.
You can use the field `$designer` in a customised post loop like so:
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
$designer = get_field('designer');
if($designer){
the_field('designer');
}
}
}
Another way to solve this might be to make sure the designer custom field returns a post object. To see the value of `get_field('designer')` you can do something like:
$designer = get_field('designer');
var_dump($designer);
A post object will contain all the relevant information (title, content, etc.). | stackexchange-wordpress | {

Add post meta based on another post meta value before publish post
I want to add a meta value to my post , which will be based on another meta value , before publish post . This is what I have tried
add_action('save_post_my_custom_post', 'add_custom_field_automatically' );

$new_meta_value = get_post_meta($post_ID,'_my_meta_key',TRUE).'to ' .' something new';
add_post_meta($post_ID, '_my_new_meta_key', $new_meta_value, true);
}
But it doesn't work . The hook fired properly , it saves only "to something new" , but what I expect the value should be "my meta value to something new" | The solution is using `added_post_meta` and `updated_post_meta` hook .
Here is the working code .

Is sanitize_text_field() is enough to save to DB?
So here is the situation. We allow users to enter input data, i.e. user_first_name and user_additional_comments. Then we use sanitize_text_field() , which is named as save.
But after this filter:
`Thomas' OR SELECT * FROM wp_user`
Is still save into DATABASE as full text. And `'` char is not escaped as `'` or `\'`.
I use `$wpdb->query("INSERT INTO A (a,b,c) VALUES ('{$a}', '{$b}', '{$c}')");` So $a has to be a valid value here, which can be inserted into db.

So is this brokes the security? | You can use wpdb insert function. It's better in every way.

How I can made a custom post type to page templates?

'has_archive' => true,
)
);
}
In my site, I want to have two pages: Index and Pictures
->Index: It had posts only of text ->Pictures: It had posts only of pictures
In Dashboard -> Posts. All posts that I did go straight to the index.
I wonder how I can access the Dashboard-> Pictures-> Add New . And each post I do, fall into the "Pictures" page.
How I can do this? | You need to add:
'supports' => array('title', 'editor','page-attributes','thumbnail')
add this to your array after 'singular name' => 'pictures'.
The thumbnail adds the featured image option to your post type.
You can access the post type archive: yoursite/archive-pictures, this will use your themes archive.php file if it exists.
Or you can create a custom post type archive template with a custom loop: archive-pictures.php.
Or you can create a custom page template and apply it to a page.
Both the post-type archive and custom page template would contain similar code: a custom post type loop like this:
$args = array( 'post_type' => 'pictures', 'posts_per_page' => 10 );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();

Wordpress Add javascript:void(0); to menu link item?
I want to add `javascript:void(0);` to menu link item instead of `#` but it is not accepting any JavaScript. Now i am thing to replace `#` with `javascript:void(0);` using filters, but could not find the appropriate filter for the task.
Can any one tell me which filter can be used for this task.
Note. I know this could be done with javascript/jQuery but this is for SEO purposes so have to do it with PHP on server side and render the correct html for google Spider, to avoid duplicate URL issue. | > I am not sure how it does effect the SEO but just to answer this question:-
You can not save menu item with `javascript:void(0);` because WordPress filter the URL using function `esc_url()` thus removing bad values. And it all happens in Nav Walker class. So you need to alter the URL when WordPress done with filtering and returning final safe HTML.
You can use filter `walker_nav_menu_start_el` if your theme does not have custom nav menu walker class OR does have this filter in walker class.

add_filter('walker_nav_menu_start_el', 'wpse_226884_replace_hash', 999);

* Replace # with js
* @param string $menu_item item HTML
* @return string item HTML

Add custom HTML to posts page

This file will be called before the other templates.
If you want to modify the template that is used to display your latest blog posts, `index.php` would be the file of choice.
`Index.php` is also the fallback template for any post object so you might want to let it as it is to avoid the special content being displayed on any other site.
You could conditionally hook into `pre_get_posts` and do your modifications there. You could create your own action hooks and fire them conditionally. There are many ways to achive modifications.

Set spesific size of featured images

I would like Wordpress to handle this automatically so that I do not have to worry about cropping my images before I upload. It is also always nice to have the original size, but We do not want the user to wait for such a large image to load. | In your functions.php you want to issue a call to set_post_thumbnail_size()
<
As with add_image_size, you provide the target width, height & whether you want the image hard cropped to these dimensions. So, for example,
set_post_thumbnail_size(427, 427, true);
will crop all your thumbnails to be a maximum of 427px high or wide, depending on aspect ratio of the original.
If you use
set_post_thumbnail_size(427, 9999);
then your images will be scaled to 427px wide without being cropped. | stackexchange-wordpress | {

How to Move the Comments Bubble to the Right Side of the Toolbar
In the admin section, the commments bubble is on the left side of the toolbar. I know how to remove the bubble. What I can't figure out is how to move it to the right hand side of the toolbar (next to 'Howdy, [username]).
Any ideas? | After you have removed the comments bubble, you add it again. The trick is that in the `$args` of `add_node` you have to set `parent` to `top-secondary`.
So it will look like this:
add_action( 'admin_bar_menu', 'wpse227079_toolbar_link_to_bubble', 999 );

'title' => 'QQ',
'href' => 'QQ',
'meta' => array( 'class' => 'QQ' )
);
$wp_admin_bar->add_node( $args );
}
Title needs the full html of the bubble, href the link where it is going and meta the class for the list item. You'll have to delve into the source code of the admin bar to find the right QQ's for the bubble. | stackexchange-wordpress | {

Correct procedure for fixing broken WP sites after WP version update
What is the correct procedure for fixing a WP site that has broken due to a recent update to the latest WP version. Assuming there are no backups both locally or via the web host.
Is it a case of switching off plugins and switching themes to see if it is restored? | I'm afraid reverting would depend on how major the upgrade was. A WP upgrade can change the database structure as well as the core code.
Your first step though should be to disable all plugins and see if the site runs without them. If so, enable them one by one until you find the problem one.
Same goes for your theme. Try one of the default themes to rule out a conflict with your own theme.
Make sure that your plugins and themes are on their latest versions too.
When I've had sites white-screen after an upgrade, those steps are usually enough to get to a fix.
If not, turn on PHP error display or logging and see where the problem apparently lies. This can be a mixed blessing as it may report a core file problem when really the issue is within a plugin or theme, hence the elimination of those earlier on. What you might see though is a compatibility issue with your hosting and the new version of WP. | stackexchange-wordpress | {
