Is it best practice to use English as the base of a translation-ready theme?
If I make a theme and add hard-coded text using `_e()`, `__()`, `esc_attr()` and so on. Could I do this in polish (or whichever language) and then add English translation po/mo files with the other languages I want to include or is this backwards and bad practice? | The default language of WordPress is always English (`en-US`). Regardless of what your site language is set to. This is what the entire WordPress community expects for the language of source strings, and how many translation projects for WordPress will be set up too.
So yes, it **is bad practice** to choose use different source language from the system you're writing for.
You could choose to ignore best practice, but with Polish you will run into a technical problem too. WordPress has a built-in limitation that you can only define two source forms of a pluralized string. This is actually a limitation of the gettext system, which is biased towards English. In their own words: "the coding standards for the GNU project require program being written in English". You could say the same of WordPress. | stackexchange-wordpress | {

How does WordPress differentiate what scripts are loaded in wp_head() and wp_footer()?
A newbie question. I have gone through the `wp_head()` and `wp_footer()` documentation and both are said to be including the scripts and styles. So my question is how does WordPress differentiate which scripts need to be in the `wp_head()` and which needs to be in `wp_footer()`. My understanding is that the `wp_head()` will include all the scripts and styles in the header section of the webpage, and calling the `wp_footer()` will again include the same scripts and styles in the footer section of the website. I know it is wrong. | wp_enqueue_scripts has a parameter which specifies if the script should be rendered in `wp_head` or `wp_footer`
The function signature is this:
wp_enqueue_script( string $handle, string $src = '', array $deps = array(), string|bool|null $ver = false, bool $in_footer = false )
Note that it is the **5th** parameter, so if you wish to not have any dependencies and use the default version number for your script you still have to supply those parameters. For example:
wp_enqueue_script( 'your_script_name', 'your_script_location', array(),false, true );

Detect the activated theme from plugin code
I would like to have my plugin detect the current "activated" theme. If my starter theme or the correct child theme is not loaded, then alert the administrator from wp-admin with an alert notification.
I can figure out the latter, but it's the former I have a question about...are their hooks or conditional tags already built into WordPress that allows me to do this easily, or do most professional wp coders have their own custom logic of doing this?

I want the plugin to detect this for the existing theme, and if a theme in the future is activated.
Many thanks for the education! | You can use `wp_get_theme` to get current theme object.

After WP installation no GD lib recognition despite module is installed
Centos 6 sys with php5.3.3, php5.6 and php7.0.
Virtual Host set with php5.3.3 Just installed WP.
Adding a plugin I get:
> Adaptive Images Error — PHP GD image library missing
> The PHP GD image library is not detected in your server. ...
php -m | grep -i gd
> gd
rpm -qa | grep php
> rh-php70-php-gd-7.0.27-1.el6.x86_64
> php-gd-5.3.3-49.el6.x86_64
I could successfully installed the same plugin in another WP installation (different virtual host, same server and php version) I have long time ago.
I don't realize what's going on. I created the virtual host using Virtualmin.
Also switched from 5.3.3 to 7.0 php version but GD wasn't found too | It was a Virtualmin control panel issue.
It displayed a wrong php version used by this Virtual Host. Virtual hosts template is set to use 5.3.3 by default (user can change it later) and it is as it was displayed but phpinfo() displayed 5.6 w/o GD module.
As stated in the question, only 5.3.3 and 7.0 were installed with DG from Virtualmin repositories.
So I solved that installing GD for php5.6 from Centos repositories.
I also have to point out that from Virtualmin CP I "changed" php version to php7.0 but it seems that was not successful because WP still complained about lacking GD. | stackexchange-wordpress | {

is_page_template not working
Hi trying this code below to get working, but no look so far. Idea is simple if page template is **page-47.php** display `<h1>Something</h1>` else `<h1>This will show on any other page</h1>` .
<?php if ( is_page_template( 'page-47.php' ) ): ?>
<h1>Something</h1>
<?php else: ?>
<h1>This will show on any other page</h1>
<?php endif ?>
Thank You | `is_page_template()` will only tell you if the page is using a _custom_ page template. Meaning a template that was created by adding the `Template Name:` comment to the file and selecting it from the Template dropdown, as described here. The function works by checking the post meta for which template was selected.
If you have created a page template using the slug or ID using the method described here, which you appear to have, then the template being used is not stored in meta, so won't be picked up by the `is_page_template()` function.
If you want to know the filename of the current template being used, regardless of whether it's a custom template or not, you can use the global `$template` variable:
global $template;
if ( basename( $template ) === 'page-47.php' ) {

Auth cookie value security risk?
A short question this time:
How much of a security risk is it when an third party gets access to WordPress auth cookie?
Can they for example simply copy the cookie and "be" logged in as the user who was the original cookie owner?
I ask this because i'm planning on passing the auth cookie value between different servers. | > Can they for example simply copy the cookie and "be" logged in as the user who was the original cookie owner?
**Yes!** with the cookie they basically have your login session. You do not want 3rd parties to get the cookie. Keep in mind there is more than 1 cookie, for frontend and for backend.
> I ask this because i'm planning on passing the auth cookie value between different servers.
I would advise against sending the actual cookie across servers. This sounds like an XY problem question, where instead of asking how to solve problem `X`, you asked how to implement or fix solution `Y`. There are better ways to handle users across multiple servers ( some of which are a part of how cookies work ), but it would depend on what you're doing that necessitates this, you'd need to ask a new question ( possibly on another stack ) | stackexchange-wordpress | {

Thanks for your help | As long as it gets registered before the `admin_menu` hook happens, it doesn't matter what file you put it in. The important part is what hook you call your function on.

Custom CSS for viewing a draft page on the frontend?

Is there any way to have draft-specific CSS (or even just a header message?) | There is probably a better way but you could add the following CSS to your stylesheet, which will add a little banner when viewing a page that has a status of draft.

display: block;
text-align: center;
}

`.status-publish`
`.status-future`
`.status-private`

I am also able to get articles from BlogSpot with specific keywords as below
I have tried to get articles from filtering with specific KEYWORD in wordpress blog but I am not able to get. What can be the URL.
I am very much newbie to wordpress. | You can modify the list of posts displayed in feed using `pre_get_posts` action. And to target only feeds, you can use `is_feed` conditional tag.
So such code can look like this:
add_action( 'pre_get_posts', function ( $query ) {
if ( ! is_admin() && is_feed() && $query->is_main_query() ) {
if ( isset($_GET['q']) && trim($_GET['q']) ) {
$query->set( 's', trim($_GET['q']) );
}
}
} );
This way you can go to `example.com/feed/?q=KEYWORD` and you'll get filtered feed (be careful - most browsers are caching feeds, so you'll have to force them to refresh it). | stackexchange-wordpress | {

change header height on 2017 theme for logged in users
When a guest sees the homepage they see the (almost) full height picture which is quite nice I think.
However, when a user logs in I'd like them to be redirected to the home page but with a much shorter picture (as the picture appears on the internal pages of the site).
I know I could redirect logged in users to a faux front page, but is there a way of changing the height of the main header picture depending if the user is a guest or logged in? | WordPress will automatically add a body class to the body tag if a user is logged in. You could potentially use this to adjust the height.
For example..
.logged-in #myElement {
...Your CSS
}
Something like this should work.
.logged-in.twentyseventeen-front-page.has-header-image .custom-header-media {
height: calc(70vh);
}

Adding a widget under an 'Add to Cart' button through a PHP snippet

I'd like to also add a small currency converter calculator widget using the same function, if possible, but my Google-fu hasn't returned useful results. Do I need to access the source code of the plugin? is there an easy way to do it? where do I start?
Hope to improve my programming skills bit by bit with your help guys. Thanks for your attention. | Your plugin for the converter supports shortcodes, so this is a good starting point. Everything should be as simple as using this code:
add_action( 'woocommerce_after_add_to_cart_button', 'astra_add_woocommerce_payments', 97 );
function astra_add_woocommerce_payments(){
echo do_shortcode( '[currency_converter_calculator lg=”en” tz=”0″ fm=”EUR” to=”USD” st=”info” bg=”FFFFFF”][/currency_converter_calculator]' );
}
You probably want to wrap the shortcode result inside a `div` or something to size it properly for your add to cart area.

* Single Post -> Show reading time: yes
* Custom Post Type "wpdmpro" -> Show reading time: no

With my code the reading time is not shown - neither in the CPT nor in the normal single post:
// Reading Time
if (function_exists('readingtime') ) if ( is_single() && ! 'wpdmpro' == get_post_type() )
{
echo '<span class="text-sep text-sep-cat">/</span>';
echo readingtime();
}
Thanks for your help. | This part is incorrect:
if ( is_single() && ! 'wpdmpro' == get_post_type() )
That essentially means:
if ( is_single() && false == get_post_type() ) {

if ( is_single() && 'wpdmpro' !== get_post_type() )
Also, the way you've combined the two `if` statements is hard to read and prone to errors. Instead, just add the first statement as a condition to the one statement:

Return to the beginning of the results of a for loop

if (!empty($search_args)) {
$search_args['posts_per_page'] = -1;
for ($i = 0; $i < count($search_results); $i++) {
if ( $search_results[$i]->ID == $currenttPostId ) {
$prevNext[] = $search_results[$i - 1];
$prevNext[] = $search_results[$i + 1];
}
}
} | You can instantly access any position in an array by specifying the index.
i.e. to get the first element of the $search_results array:
$first_result = $search_results[0];
_Note if you're not used to working with arrays, they are "0" indexed in most languages, which means the first element's index is 0, the second is 1, etc._
This is what your loop is basically doing as well. Each time it accesses a different number directly, $search_results[$i] is just putting the value of $i in the same spot as I had the 0 above.
You can **also** change the value of $i in your loop if you want to start the loop over, for instance. Adding the line:
$i = 0;
...would send you back to the beginning. However I would not recommend you work with the index of a loop until you are quite comfortable with them. | stackexchange-wordpress | {

How do I make WordPress send an email to the user when his account gets approved (manual by me)

Is this possible in WordPress core, or is this something that has to be added manually?
Thanks in advance. | What you are trying to do - approve a user in the admin and send an email - must be done using action and filter hooks, either by a plugin you're using or your own code in your child theme or a plugin.
To approve a user, take a look at the `user_register`, `edit_user_profile`, `edit_user_profile_update` and `load-user-edit.php` hooks to get started. In your own approval code, you would then structure your email and send it with the `wp_mail()` function.

checked: !!textSize,
onChange: function(){
textSize ? props.setAttributes({ textSize: '' }) : props.setAttributes({ textSize: ' big' })
}
So textSize controls the checked status and holds the classname, if checked. You can use the textSize string in other elements className: attributes. | stackexchange-wordpress | {

How would I find where this particular SQL query is built for orderby to debug this ? | You can't pass SQL directly as query parameters. The only valid values for `orderby` are covered in the docs for `WP_Query`.

How to take shortcode and content separately from a page?
I have a page with content and shortcode for the contact form. I want to display the content of the page in one div and the shortcode in another div(that means the form should render in another div). How to implement this? I tried
`<?php remove_filter( 'the_content', 'do_shortcode', 11 ); the_content(); add_filter( 'the_content', 'do_shortcode', 11 );*/ ?>`
for filtering the content only...but it displays the shortcode as it is.([contact-form-7 id="72" title="Contact form 1" html_class="col-lg-8 col-md-8 col-sm-12 col-12 dose-contact-form row"]).How to ffx this? | I found the solution. I used the following codes and it worked for me . To remove the shortcode from the content, I Used this `<?php $content = get_the_content(); $content = preg_replace("/\[.*]/m", " ", $content);
$content = apply_filters('the_content', $content); $content = str_replace(']]>', ']]>', $content); echo $content; ?>`
and the following code to get the shortcode only from post content ` <?php $pattern = get_shortcode_regex(); $matches = array(); preg_match_all("/$pattern/s", get_the_content(), $matches);
echo preg_replace_callback( "/$pattern/s", 'do_shortcode_tag', $matches[0][0] ); ?>` | stackexchange-wordpress | {

How to always display a specific post from the search result first

)
);
$taxonomies_selected[$taxonomy] = (get_query_var($taxonomy)) ? get_query_var($taxonomy) : '';
} | One way to show a specific post always first is to add a sorting loop between your post query and rendering loop.

foreach ( $my_posts as $post ) {
if ( "some logic here" ) {
array_unshift($sorted_posts, $post); // use php function to prepend the post to the sorted array

Migration / convert an existing site to WordPress
I have an advertisement site that I create with PHP and MySQL.
The structure of the database is very simple:
* Tables: ads, type of ads, user, and images.
* Each ad has an ad type (offer or request)
* An ad has one or more associated images.
* A user can post multiple ads.
The site contains more than 10 thousand registered ads.
How do I export data to a WordPress database? | Since it is a custom site and database structure, there is no easy way to import your data into WordPress.
I would suggest you instead focus on how you would accomplish the same thing within WordPress. In other words, start by pretending you don't have those 1,000's of ads, and build out your way of tracking ads in WordPress. Then, when that works, you can think through if there's any way to move some of the data.
If not, it would probably be easier to leave the old ads as-is and have the front-end run both implementations (pull from both data sources).
You _could_ build a custom plugin that allowed you to continue using the custom database structure you already have, yet give you an editing capability through WordPress. After all, WordPress is quite comfortable with mySQL.
So consider what you are hoping to gain by integrating the site with WordPress, how you would integrate it with WordPress in the first place, and then whether or not its worth bringing in your old data. | stackexchange-wordpress | {

Generate dynamic ID's for each accordion button
Hello my awesome WP peeps. I have a situation where I have an accordion and I want to add a show/hide all button for each new accordion I add.
So I'm able to generate the post ID in the admin for each new button like:
<button id='wp_1'></button>
Im also able to add the jQuery code for an onclick event that will open the accordion like:
$('#wp_1').on('click', function () {
$('.panel-collapse').collapse('toggle');
});
The problem is, Im not sure how to generate multiple dynamic ID's so that each button only opens up the accordion below it. So in the screenshot below, how do I get WP to also generate an onlclick for #wp_31? Appreciate the help.

How to call plugin function per site in a multisite?
**My goal is to be able to call a plugin function per site and of course it has different result based on the site data.**
e.g.
I have a plugin called: **sample-plugin.php**
Inside it has a function called:
function sp_echo_site()
{
echo get_site_url();
}
I have a multisite inside has 3 sites: e.g. animals.com, fruits.com and people.com
And in a network level, I wanted to call the `sp_echo_site()` function.
I wanted to do the following loop, however of course it doesn't work, How can I make this work?
foreach (get_sites() as $site)
{
$site->sp_echo_site();
}
How can i achieve the following result?:
animals.com
fruits.com
people.com
Is this possible? Or do I have to go to database? Or any other alternative methods? | You're almost there...
If you have this in your plugin:
function sp_echo_site() {
echo get_site_url();
}
Then you call this function as this:
sp_echo_site();
And this line will run this function in the context of current site.
So you'll have to do something like this:
if ( function_exists( 'get_sites' ) ) {
foreach ( get_sites() as $site ) {
switch_to_blog( $site->blog_id );
sp_echo_site();
restore_current_blog();

How to elect position of new item output in a dropdown when using add_filter
Hello I am using the suggested snippet here to add a new term to a dropdown menu: <
which is:
add_filter( 'job_application_statuses', 'add_new_job_application_status' );
function add_new_job_application_status( $statuses ) {
$statuses['example'] = _x( 'Example', 'job_application', 'wp-job-manager-
applications' );
return $statuses;
}
That works fine but my new single entry 'example' is output at the bottom of the dropdown list, I'd really like it to be in 2nd place. Is there a simple way to do this? Thank you. | You can achieve this by using the array_splice() function in conjunction with array_merge(). Here is an example:
function add_new_job_application_status( $statuses ) {
return array_merge(
array_splice( $statuses, 0, 1 ),
array( 'example' => _x( 'Example', 'job_application', 'wp-job-manager-
applications' ) ),
array_splice( $statuses, 1, -1 )
);
}
add_filter( 'job_application_statuses', 'add_new_job_application_status' );
This function takes the first item in the `$statuses` array, your custom example field, the rest of the items in the array and merges it together. You need to do it this way as splice doesn't support inserting a multi-dimensional array at a specific point in an array. Hope that helps. | stackexchange-wordpress | {

Loading page template into shortcode
I am attempting to load a page template into a shortcode so I can easily load the content wherever I want.
I have done some research and many people have said this code has worked for them but for some reason this does not seem to load my template right as I just get a blank page.
I know the shortcode is executing as it does not show as plain text so I'm guessing there is a problem with the way I am loading the template.
Any help is much appreciated .
public function register(){
add_shortcode( 'sponsor_main_page', array($this,'my_form_shortcode') );
$RegistrationFormId = esc_attr( get_option( 'ik_form_id' ) );
}
function my_form_shortcode() {
ob_start();
get_template_part( 'template-sponsors.php' );
return ob_get_clean();
} | `get_template_part` takes slug as first parameter and not filename.
So it should be:
get_template_part( 'template-sponsors' );
And with more details... This function takes two parameters:
get_template_part( string $slug, string $name = null )
And inside of it, the name of a file is built like this:
if ( '' !== $name )
$templates[] = "{$slug}-{$name}.php"; $templates[] = "{$slug}.php";
So, as you can see, the `.php` part is added automatically. So your code will try to load file called `template-sponsors.php.php` and there is no such file, I guess. | stackexchange-wordpress | {

Title has word broken when viewed in mobile
I am designing a website using the Renden Free theme, and my problem is that some long titles, when viewed in mobile, have words broken in half. For example:
![Screenshot](
As you can see, the word "Corporal" gets broken and split in two lines.
Why is this? Is there any way to control where does Wordpress split the title? | It's possible that a word-break CSS rule could fix the problem. You could apply it globally with this
body {word-break:normal !important; }
Or maybe this:
body {overflow-wrap: normal;}
But it might be better to apply that to the specific class/id used by the title. And ever further tweak it to only apply that rule to smaller screens via the media query.
But you could add the above to 'additional CSS' in your theme customization to see if that will help.

Multiple pagename WP Query

get parent and childs from hierarchcial taxonomy
I have a hierarchical taxonomy and I want to show only children from 1 parent.
For example, the taxonomy looks like this:
- Events
-- Location
-- Date
- Region
-- State
-- StateCode
When I use my code, I get all child values...
$terms = get_terms( array(
'taxonomy' => 'events_category',
'hide_empty' => false,
) );
foreach ($terms as $term) {
if ($term->parent != 0) { // avoid parent categories
$options[] = array('label' => $term->name, 'value' => $term->term_id, 'id' => $term->term_id);
}
}
Is it possible, that I can modify this lines to get only the children from Events for example? | Yes, you can.
`get_terms` function takes `$args` as first param. And you can use the same args as with `WP_Term_Query`.
Two arguments that may interest you are:
* `child_of` \- (int) Term ID to retrieve child terms of. If multiple taxonomies are passed, $child_of is ignored. Default 0.
* `parent` \- (int|string) Parent term ID to retrieve direct-child terms of.
So if you want to get only the terms that are children of Event term, then you can use this code:
$terms = get_terms( array(
'taxonomy' => 'events_category',
'hide_empty' => false,
'child_of' => <EVENTS_TERM_ID>, // <-- you have to replace this with the term id of Events term.
) );

Updater user with multiple roles

Override theme style rule in Gutenberg
I have a theme that adds the following CSS rule inline through the Customizer to style the hover state of links in post content:
.entry-content a:hover {
color: <color selected in the Customizer>;
}
I'm adding support for Gutenberg in my theme and I'm having some issues with the link button block. The previous rule is overriding the following default core block style rule that applies the same link button color selected in Gutenberg for the button active, focus and hover states:
.wp-block-button__link:active,
.wp-block-button__link:focus,
.wp-block-button__link:hover {
color: inherit;
}
Checking the Inspector, I see that the last rule applied is the first one instead of the second one, which I thought it was more specific. That means that the link button color selected in Gutenberg is not honored.
Any ideas on how to fix this?
Thanks in advance | `.entry-content a:hover` is more specific than `.wp-block-button__link:hover`.
According to the rules of specificity, the first selector contains 2 class selectors (`.entry-content` and `:hover`), and 1 type selector (`a`), for a specificity score of `0,0,2,1`.
The second selector, on the other hand, contains 2 class selectors (`.wp-block-button__link` and `:hover`), and no type selectors, for a score of `0,0,2,0`.
It wasn't clear to me from your question where exactly the second set of selectors was coming from, but assuming that you can't edit them, the solution would be to exclude Gutenberg buttons from your original selector. You can do this with the `:not` pseudo class:
.entry-content a:not(.wp-block-button__link):hover {
color: <color selected in the Customizer>;
}
Now your Customizer-selected colour will only apply to links that are not block editor/Gutenberg buttons. | stackexchange-wordpress | {

Set custom post type terms by id without knowing taxonomy
For a custom post type with multiple taxonomies, is it possible to set the post terms without explicitly knowing which taxonomy the term falls under?
I have an array of term ids which may contain a mix of terms from any one of three taxonomies. The only function I've found to add terms to a cpt is `wp_set_post_terms` which requires the taxonomy slug. | It's a bit confusing, the documentation for `wp_set_post_terms()` claims that the `$taxonomy` argument is "Optional", but in looking at the source it appears that all this means is that its default value is `post_tag` if you omit the argument. If you attempt to pass `null` or an empty string, it won't work.
So I think the solution then would be to first get the taxonomies of the given IDs, and then set the terms for each taxonomy separately.
$post_id = 123; // For example.
$term_ids = [ 1, 2, 3 ]; // For example.
$terms = [];
foreach ( $term_ids as $term_id ) {
$term = get_term( $term_id );
$terms[$term->taxonomy][] = $term_id;
}

HTTP ERROR 500 after installing child-theme [Wordpress]
I just created and activated a child theme and now I'm getting the HTTP ERROR 500. I've deleted the child theme through FTP and still getting the error.
Also tried changing `wp-content/themes` to `wp-content/themestemp` and that allows me to get back into the wp-admin panel but when I'm trying to install a new theme Wordpress can't create a new directory for the themes.
Is there a way to recover the primary theme?
Thanks in advance! | In general a `500 Server Error` can be solved (or at least be correctly identified) by looking at php logs. If you are on a shared hosting you should have something in your hosting's control panel to check the logs (look for `Error` messages), if you are self-hosting on your own vps you can usually find the logs in the `/var/log` directory.
This said, the current theme in WP is stored as two entries in `wp_options`, which are `template` and `stylesheet`. Name back the theme directory like the original one, write down the directory name of the original theme, and put it as the field value for `wp_options.template` and `wp_options.stylesheet`.

Add a query var for section:
function my_query_vars( $vars ) {
$vars[] = 'section';
return $vars;
}
add_action( 'query_vars', 'my_query_vars' );
I created the pattern for your section (which can be 1 or 2) and used $matches[2] to set the "name" parameter, which is your slug. Then I set the "post_type" to "post" to be sure WordPress is searching for a post.
Because I added the query var you can then do:
$section = get_query_var( 'section' );

Why do I have categories with duplicate slugs?
I have inherited a WordPress site, where I'm trying to resolve a weird-looking issue related to post categories.
In the `Edit Post` page, there is nothing showing up under `Categories` (Gutenberg editor).
![missing categories](
Thinking this is strange, I went to the `Categories` page. There, I saw many categories with the same slug.
![list of duplicate posts](
This is even more strange to me, since I thought categories couldn't have the same slug. I figure this is where the issue lies.
So I'd like to start deleting these duplicate categories, but there is no `Delete` link – only `View`.
![view button visible, but not delete](
Can anyone shed some light on what might be happening here? Can I fix this directly in the database somehow? | I found a few rows in the `wp_terms` table with a `term_id` of `0`.
There was also some entries in `wp_term_taxonomy` with `term_taxonomy_id` and `term_id` both set to `0`.

Also, I had to fix some issues with the database structure. In the `wp_terms` table, I had to make sure that `AUTO_INCREMENT` was enabled for the primary key field. | stackexchange-wordpress | {

Does WordPress still ask for FTP credentials for each file operation?
There is a reply from 2014, that is a great answer to a question I have, but WordPress changes, and I'm wondering if this is still true, "WP Filesystem API will ask for FTP credentials, but it will do so for each operation. They aren't stored persistently."
Where does wordpress store the FTP credentials?
If this is still true, I'm guessing that the interaction between WordPress and the host would be that the host would send the default (main) FTP credentials unless a specific account were added to wp-config. | Not quite right. WordPress only requests FTP credentials if it cannot modify files. That's the important bit from Rarst's reply. This all comes down to who owns the files and does php (and WordPress) have access via either the group and/or user to modify these files?
The default is to use php's filesystem extension which does not require FTP at all. In the case of using FTP, credentials would always need to be set either within the WordPress admin for each request or in wp-config.php.
Here's a good overview of what's going on: What security concerns should I have when setting FS_METHOD to "direct" in wp-config?
The codex for `FS_METHOD` lists the different options for WordPress interacting with the file system.
To answer your question, nothing has changed with regards to the way WordPress interacts with the filesystem with regards to FTP.

Add a containing DIV to core Gutenberg blocks
The design I am working with calls for each Gutenberg block to have a coloured background (white in this case) with `max-width: 1160px` and the content within to have `max-width: 800px` and centered. Similar to the image below:
![enter image description here](
Which would need a setup like this:
<main class="site-background">
<div class="width-1160">
<p class="width-800">Some text content...</p>
</div>
</main>
At this time we are only using core Gutenberg blocks but the markup it produces is similar to the below, without the containing `<div>`:
<main class="site-background">
<p class="width-800">Some text content...</p>
</main>
Is there a way to add a containing `<div>` to all Gutenberg content blocks that will be safe when core updates? | I'm sure there are other ways e.g. with CSS only or Add custom class to core blocks in Gutenberg, but regarding:
> Add a containing DIV to core Gutenberg blocks
one way could be with the `render_block` filter:
add_filter( 'render_block', function( $block_content, $block ) {
// Target core/* and core-embed/* blocks.
if ( preg_match( '~^core/|core-embed/~', $block['blockName'] ) ) {
$block_content = sprintf( '<div class="some__class">%s</div>', $block_content );
}
return $block_content;
}, PHP_INT_MAX - 1, 2 );

How to get posts without author? | That won't be as easy as you'd like to... `get_posts` uses `WP_Query` to get posts and if you take a look at `WP_Query` code, ten you'll see, that 0 is used as empty in there (<

On the other hand, if you already have 0s in there, then you'll have to use custom SQL to get these posts. One way to do this will be with this code:
global $wpdb;
$ids = wp_list_pluck( $wpdb->get_results( "SELECT ID FROM {$wpdb->posts} WHERE post_type=post AND post_author=0" ), 'ID' );

It is basically a PHP script that is written for WordPress usage (but of course can be used with any database).

It enables you to make database queries based on regex, with a 'dry runs' - you will see a preview of the data that will be changed, but no real changes would be made. Also, it is serialization aware, meaning, if the variable you are replacing is inside a serialized object, it will safely be replaced, without breaking the serialization.

`admin_head` is an action that allows you to print your custom code inside `<head>` tag of admin sites. But if it's inside of `<head>`, then some output is already sent to the browser, so you can't perform any redirections any more.
As you can see here Actions Run During an Admin Page Request, the `admin_head` is called after the scripts and styles are already printed.
So you should run your code using some hook that is fired before any output is sent to the browser. You can use `wp` hook for example.

Bulk activate a theme on multisite

function switch_all_multisite_themes() {
foreach ( get_sites() as $site ) {
switch_to_blog( $site->blog_id );
switch_theme( 'theme' ); // for example 'twentyten'
restore_current_blog();

The easiest way is to export DB to SQL, find and replace all occurrences of old URL with the new one. But... This can break your DB - some things are stored as serialized objects in DB and such simple change of strings will break these objects and make them impossible to unserialize.
Another way is to use tool like Interconnects Search Replace DB | stackexchange-wordpress | {

Prevent Wordpress Automatic Logout
I am using this function which is supposed to prevent wordpress from automatically logging me out. However, I am still being logged out every so often.
function my_logged_in( $expirein ) {
return 31556926; // 1 year in seconds
}
add_filter( 'auth_cookie_expiration', 'my_logged_in' );
Is there another solution to this? | As we know by default WordPress keeps logged in for `48 Hours`. If we check "Remember me" while login then it will keep login for 14 Days.
If you want to set the logout timeout you can use this code as:

if( $remember && user_can( $user_id, 'manage_options' ) ){
$expiration = 31556926;
}

How to Disable Right Click on wordpress Dashboard(Admin Area)
Just want to know how to disable right click on dashboard(admin area) side of the wordpress.already used following code for frontend(user area).
body {
-webkit-user-select: none;
-moz-user-select: -moz-none;
-ms-user-select: none;
user-select: none;
} | Use the selector `.wp-admin` to make sure you are selecting only the wordpress admin area.
html body.wp-admin {
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
The code above will prevent the user from selecting/highlighting the page content.
If you really want to disable right click, just use a simple JS code like:
<script>
document.oncontextmenu = new Function("alert('Right click is blocked.'); return false");
</script>

Posts page not showing correct image
The Wordpress site I am working on has a static front page, and all posts are sent to another page (entitled `blog`).
The images on this Posts page are random pretty shots, and not in the Media collection at all. When I click on a post however, I do get the correct image in its new page.
How can I either get the correct image in the Posts page, or remove these images from the Posts page entirely?
Wordpress is version 5.1, and the theme is something called `Simple Business Pro`. Thank you! | If the theme you're using is this: < then... This is the code responsible for images on the blog page:
<?php
if (has_post_thumbnail()) {
the_post_thumbnail('nimbus_722_400', array('class' => 'nimbus_722_400 img-responsive'));
} else { ?>
<?php if ( (simple_business_wp_get_option('fp-news-thumbs-toggle') == "1") || (simple_business_wp_get_option('fp-news-thumbs-toggle') == "") ) { ?>
<img src="<?php echo get_template_directory_uri(); ?>/assets/images/preview/722x400-<?php echo rand(1,8); ?>.jpeg" class="nimbus_722_400 img-responsive" alt="<?php the_title(); ?>" />
<?php } ?>
<?php } ?>
As you can see, it will show post thumbnail, if it is set. And if there is no thumbnail set and some option is set to true, then it will show random image from assets.
So if you're seeing some random images on the blog list, then probably you haven't set featured images for these posts. | stackexchange-wordpress | {

WP showing "warning: call_user_func_array()", What to do?
I am currently working on designing my blog and am almost done but when I updated to 5.1 WordPress version in XAMPP, it started showing up this error message:

function 'disable_embeds_rewrites' not found or invalid function name in
E:\xampp\htdocs\wp\wp-includes\class-wp-hook.php on line 286
The blog theme(with custom callback for comments) I had just designed was working properly in last version of WordPress but this error started showing up just after I updated my WordPress.
Please provide me some solution! | The error you're getting is showing, because somewhere on your site (your theme or one of your plugins) is registering a filter function that doesn't exist.
Somewhere in your code, there will be such line (or similar to it):
add_filter( 'rewrite_rules_array', 'disable_embeds_rewrites' );
It may use different hook, so it may also look like:
add_filter( 'XXX', 'disable_embeds_rewrites' );
The problem is that the function `disable_embeds_rewrites` doesn't exist on your site.
The easiest/quickest way to fix it is to remove the line above.
PS. But you should be careful. Maybe that filter is needed on your site. So when you find it, you should contact the author of that part of code (plugin/theme) and report it as a bug. | stackexchange-wordpress | {

Why does paginate_links() reload the entire page? and can you make it reload only a specific div?
Beginner here; apologise for any obvious mistakes.
I have a post list on my homepage showing 3 posts at a time and using `paginate_links()`.
When I click on page2 or next in the paginate_links(), it reloads the entire homepage(and scrolls to the top of page.
Need to scroll down back to post list) and then the page2 of the post list is shown.
My homepage has a lot of other content; so is there a way for `paginate_links()` to work by reloading only the post lists instead of the entire page? | `pageinate_links` is a function that retrieves paginated link for archive post pages.
So yes - there are links. And links works exactly this way - if you click on it, you will go to the url that is connected with that link - so the page will get reloaded.
If you want the link to cause a partial reload of only one div (or other container), you'll have to write your own code, that will:
1. Prevent the link reloading the page when clicked.
2. Send AJAX request to the server and obtain new content of that container.
3. Replace the content of container with the new content received from server. | stackexchange-wordpress | {

How to get full native language instead of iso?

Invalid key on activation and password reset
I am in a pickle now, about to release a Wordpress-based app and I can't get the registration complete because password set/reset key is **sometimes** invalid.
I say sometimes because when the user is registered, he gets link to set the password, and that is always invalid. Then he is asked to enter his username to reset the password and a new email is sent. That link is also invalid, however, if he requests a new password reset email again, then the link is valid.

`
When the key is with symbols, it gets denied, example:
`

What could be happening here? Please help!
**Edit:**
I repĺicated this behavior again to make sure, and this time it took 4 tries. So I am guessing that if you keep trying to get a clean key, it works. Why would this be happening? | Problem solved!
I had a filter hooked onto `random_password` filter to generate passwords with custom rules and `get_password_reset_key` uses the function `wp_generate_password` to generate the key, and that is why I was getting the behavior I was getting.

Is it possible to access plugin data from a custom feed template?
I'm trying to use `current_user_can` in a custom feed template (created using `add_feed`) to check if they have a particular Memberpress membership plan in order to access the feed, but while I can get other user data (e.g. `$current_user->user_login` outputs the username), I can't use the plugin function.

Why submenu item's background color is not changing by css?
I am developing child theme based on Accelerate by ThemeGrill. I am trying to change submenu item's background color. However it is not affacted by any selector.
I have tried to add following to Additional CSS options:
*{
color: #00df00 !important;
background-color: #50df50 !important;
background-image: none !important;
}
This results in every item in the page to be green except submenu's backgroud which is still gray. However text of the submenu items were changed, so the submenu items are partialy affected by this css.
Why is the background color of submenu items not changing? | CSS is a game of competing priorities. When two rules conflict, whichever one has the higher specificity wins.
If you have these rules and something is not affected by it, then something else has a higher specificity.
Since you have specified the !important tag, whatever is trumping you is also using the !important tag. Then it is trumping you by also having a higher specificity in another way (or even just by coming after yours).
You need to inspect the element and find out the source of your competition, then write a rule to trump it.
The difficulty in trumping !important tags is the precise reason they are absolutely not recommended.
No one else can diagnose this further without seeing the actual page where it is happening (since you don't know where the other style rules are coming from). | stackexchange-wordpress | {
