Css loads very slow
I have already searched about the problem but I didn't find something i understand, specifically for WordPress. Should I edit function.php of my theme somehow?
When the site loads the ugly sitemap appears and after a moment the site appears correctly.
I already fixed (only) the CSS errors seen in console and minified a big basic .css file
If you need the URL please tell me. | I assume, because you said that at first moment site is ugly and soon after that site looks fine that problem is in position of css in your HTML code. For example if you load external .css file in your footer it will load after everything above, so you will see your site "as ugly" because that part of your code is loaded before, and your browser do not now how to style your site, until it load css.
If that is the case, put your css in header of html. Also, if you provide site link I can see more. | stackexchange-wordpress | {

I am using CloudFront and Cloudflare at the same time. Is that good?
I'm running my site using two CDNs. I primarily just use Cloudflare for security, and CloudFront for complete CDN. | You will likely get better performance out of using Cloudflare alone for both security and performance.
Cloudflare has the following performance advantages of Cloudfront:
* CDN WebP support in Polish
* Support for HPACK in their HTTP/2 implementation
* Ability to cache anonymous page views with WordPress
* Railgun
Additionally, Cloudflare has Flat rate pricing so no need to worry about bandwidth fluctuation, unlike with Amazon. In terms of network size, AWS in 16 cities where Cloudflare is in 101. | stackexchange-wordpress | {

Use htaccess to redirect wordpress non-existent page to homepage
For seo reasons I need to redirect domain.com/index.html and domain.com/index.htm pages to homepage without breaking anything. I tried some options so far but none of them work. Plain Redirect 301 commands get the site into redirecting loop. Here is what I've got so far
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [R=301] # this two lines
RewriteRule ^index\.htm$ - [R=301] # added by me
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule> | You can achieve that using
RewriteEngine on
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.htm\ HTTP/
RewriteRule ^(.*)index\.htm$ /$1 [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.html\ HTTP/

How to Remove Slug From Database?
**For example:**
* `mydomain.com/embed` automatically redirecting to homepage although I haven't set redirection.
* I want to add a page in my website name embed and for this page URL
automatically becoming `mydomain.com/embed-2`.
I checked everything, there is no existing or trash post, page, tags Etc.
**How to remove that existing embed slug from the database?**
Thanks | I don't exactly know about the word `embed`, but by default WordPress reserves & uses these sort of words for internal use. I tried to create a page slug named `embed` but it wouldn't work for me either on my localhost or on my live server.

How do I future proof my older WordPress theme?
The latest version of my WordPress theme has a bug. The version before it does not have this bug. Is it okay for me to stay on the previous version long-term? I don’t use many plugins, mainly HTML and custom CSS which are written for my child theme. Is it possible for me to make a particular version of my WordPress theme future proof? Specifically, compatible with future WordPress versions? | I'd say it's a security risk that will only increase with time. How do you see making it "future proof"? It's like asking a car manufacturer for a car that's accident-proof - they don't make these. That's what car insurance is for. The WordPress version you're on is only good for having protections against already-discovered vulnerabilities. New ones keep appearing, so patching them is part of the reason why new versions keep coming out.
So, to extend the analogy of automobiles, your "car insurance" would be to pick a reliable host with good support, keep your WordPress up-to-date, and follow best-practice advice for protecting WordPress site against attacks (lots of it out there, just do a simple web search) while balancing it against your particular situation (because not all security advice can always realistically be followed in all cases). | stackexchange-wordpress | {

How to add padding between posts
Ultimately, I'm really confused on how exactly you create a single class that affects each post in a static home page "recent post" type content area. I want to essentially have it where there's a post with a background, a space, then the next post with the same background, but not have the background behind all the posts. I hope that makes sense. Here's the code I have, but no matter what I do, I'm only able to add a class for one post at a time with the ID.
<ul>
<?php $the_query = new WP_Query( 'posts_per_page=5' ); ?>
<div class="new_home_single"><?php the_post()?></div>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a>
<?php the_excerpt(__('(more…)')); ?>
<?php
endwhile;
wp_reset_postdata();
?>
</ul> | Wordpress already generates class for each posts, you can use these classes using the **`post_class`** function.
**Note:** The function can be used either within the loop or by passing the `$post_id`
So you would have
<ul>
<?php $the_query = new WP_Query( 'posts_per_page=5' ); ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>
<div id="post-<?php the_ID(); ?>" <?php post_class( 'post' ); ?>>
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a>
<?php the_excerpt(__('(more…)')); ?>
</div>

do I need to change the default database prefix?

See I have four or more worpdress site on one server(not multiplesites),like:<
All of them are using wordpress and sharing a same database prefix.Is there any problems for that when it comes to site preformance? | If it is easy to do, best practice is to have all wordpress installs use their own DB.

WordPress update 4.7 - the 70.000+ news posts became "Uncategorized"
Dear WordPress experts,
I updated a news website to Wordpress 4.7 from 4.6.1 or 4.6. The update ran well, the routine message showed up saying that the database as well should be updated. I clicked "OK". In a short while a 504 Gateway Timeout error occured. Afterwards, in the WordPress dashboard none of the 70.000+ posts has a category, all of the posts are marked as "Uncategorized". Once I try to edit and choose one of the 300+ categories and publish - nothing changes, the post remains "Uncategorized".
In PHPMyAdmin all the tables are fine, wp_terms is fine, all the categories with their IDs are listed there. However, the front-end and the WP-dashboard show no category to be assigned to a post.
PLease advise. | I have solved the issue. The max_execution_time (the time limit for server requests) was too short and seized the database update after 4.7 was installed.
I have just downgraded the WordPress version back to the previous version 6.1: \- WP-includes and WP-admin folders were overwritten along with the root files of the WordPress install (robots.txt and wp-config.php are not affected at all as they are not included in the fresh WordPress release files).
After the downgrade all the categories are fine, just the news articles that were published in the meantime had "Uncategorized" category that I easily removed and assigned them correctly in the dashboard.

When importing database, it shows error
I was importing my website' database on to another server but it is showing this error which I have no idea about:
![](
I tried importing the database multiple times but failed. I also checked 'Add Drop Table' field that comes when exporting the database file but it didn't do anything. | This issue is as a result of your server not supporting the `utf8mb4_unicode_520_ci` collation type.
To resolve this you should convert the collation for all tables with `utf8mb4_unicode_520_ci` to `utf8_general_ci`
**If you're exporting through phpmyadmin, you can:**
1. Click the "Export" tab for the database
2. Click the "Custom" radio button
3. Go the section titled "Format-specific options" and change the dropdown for "Database system or older MySQL server to maximize output compatibility with:" from NONE to MYSQL40.
4. Scroll to the bottom and click "GO".
**OR run the following query on each of the affected tables:**
ALTER TABLE myTable CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci

CSS in child theme to replace !important in parent theme
I am trying to edit the colours of certain elements in my child theme on wordpress (the specific theme is Kleo if relevant). I have been doing fine adding in custom css to the child, however it seems the parent theme has labelled a few options as '!important' (at least that is what shows up when I inspect the elements in chrome). I'm not sure why they've done this but it makes for somewhat clunky code when I subsequently have to include '!important' on everything else I edit to overcome the parent's '!important'.
I was wondering if anyone knows of ways to edit the parent theme's css or of any other way of getting around this problem.
Many thanks for any help | You can overwrite an !important option with another !important but with a deeper selector. Example: the next snippet
.container {
width: 800px !important;
}
should be overwritten by
html .container {
width: 800px !important;

cookie free subdomain and @font-face

font-style: normal;

src( format('woff'), etc.

You may therefore have an issue with your URLs. Your paths in the first (multiple-line) example are relative to your css file; is your 'fonts' directory in the same directory as the css file? If not, that is your issue (or one issue).
Also, check your font file formats. All your fonts have 'ttf' (TrueType) as the first file extension, but they can't also be .eot (Embedded Open Type), .svg (Scalable Vector Graphics) and so forth: those are different file formats.

I want to create an archive and single page for a custom taxonomy for a custom post type

wp_kses allow checkbox class and checked
I'm having a hard time getting `wp_kses` to allow the class for an input. These approaches didn't work:
input' => array(
'type' => true,
'class' => true,
'name' => true,
'value' => true,
'id' => true
),
also with `array()` for class it still is not returned.
Checked is also filtered.
Why do I need this? Well, long story short, the input is in a table which needs to be escaped prior to being printed with echo or with ajax. | According to the codex, you should define your **`wp_kses`** list of allowed html elements as below with `array()` instead of `true`

<?php else: ?>
<?php endif; ?>
or
<?php if (is_page()) { ?>
<?php } else { ?>
<?php } ?> | As far as I can tell, there's no performance difference. And both styles are acceptable by WordPress Coding Standards as you can read in:
> Braces should always be used, even when they are not required:
and
> Note that requiring the use of braces just means that single-statement inline control structures are prohibited. You are free to use the alternative syntax for control structures (e.g. if/endif, while/endwhile)—especially in your templates where PHP code is embedded within HTML

WP REST API: Order posts by meta value (acf)?
I'm requesting posts with the WP REST API and need to sort them according to an ACF field. It's value represents a date (numeric, jQuery date format yymmdd). I know how to do it with a normal WP_Query and tried to do the same using the rest api:
mydomain.com/wp-json/wp/v2/posts?filter[orderby]=meta_value_num&filter[meta_key]=my_field_name&filter[order]=DESC
In fact I'm using a custom post type that's registered with the rest api and everything else is working perfectly, so I think its not a cpt specific issue?
But the posts show up in default order (their creation date, latest to oldest). What am I missing? Is this orderby parameter not supported by the rest api? If so, how can I implement it myself?
Any other workarounds, suggestions? Really looking for a solution! Thankful for any hints! | I'm guessing you haven't exposed meta_key and meta_value to the REST API with the rest_query_vars filter, so this should do it:

$current_vars = array_merge ($current_vars, array ('meta_key', 'meta_value'));
return $current_vars;
}
add_filter ('rest_query_vars', 'my_add_meta_vars');
Then you can refer to meta_key and meta_value in your query.
Be aware that this obviously exposes all your post metadata to the API, which has potential security implications; I believe that's why it's not activated by default. | stackexchange-wordpress | {

Is it possible to install two mail plugins together in a single Wordpress site? How to do it?

Writing functions in WordPress functions.php that don't replace a WordPress core function

How to display the category featured images

Accessing content from third party as native posts in Wordpress
Can Wordpress be architected to use external content accessed over HTTP instead of reading and writing to a database ? Size of the content available remote is simply huge and potentially modified by other tools as well. So importing into database is not a viable option.
Is there any product available that can abstract wpdb layer and use HTTP calls instead ? | Simple answer is "no". Whatever the API you might use it will be too slow to return a page in a timely manner, unless you have the other HTTP server on your LAN, in which case you should just access its DB directly.
What you can do is cache the "external" content in your DB and serve it the "normal" wordpress way. It means that instead of overriding the `wpdb`class you will need to write code in "higher layer" that will be responsible to sync items from the remote site whenever it is needed.
Other obvious options are to use iframes or oembed to embed the remote content in your wordpress pages. | stackexchange-wordpress | {

<span style="color: #000000;">By AUTHOR FOR</span> <?php the_meta(); ?> </p>'; ?>

<p style="text-align:left;font-size:18px;margin-bottom:5px;"><span style="color: #000000;">By AUTHOR FOR</span> <?php the_meta (); ?></p>
However I'm not sure you want to use `the_meta ()`, because all values get displayed, and in an unordered list. (Reference: the_meta.)

<p style="text-align:left;font-size:18px;margin-bottom:5px;"><span style="color: #000000;">By AUTHOR FOR</span> <?php echo get_post_meta (get_the_ID (), 'my-author-meta-key', true); ?></p>

Backticks (`) Instead of Single Quotes (') in an SQL Statement?

$sql = "CREATE TABLE IF NOT EXISTS $table (

* What is the proper term for the oddball quotes :)
* Why are they used instead of ' ?
* Is this only pertinent to MySQL? WP? Php?
* Where can I find a technical reference for this sort of thing so I don't have to bug you fine folk? | Backticks and regular quotes (both single and double) have distinct meanings in SQL. Quotes indicate a literal string, whereas backticks are quoted identifiers. This isn't specific to WordPress, but rather a general way in SQL of quoting columns or tables.
For example, imagine you're running a query comparing two columns:
SELECT * FROM wp_posts WHERE post_name = post_title
If you compare with single quotes (`'post_name' = 'post_title'`) this would compare the literal strings, which are never equal. However, with backticks, it would refer to the column.
Why use backticks at all? If a column is named the same as a reserved word in SQL, or contains a space, you need to quote it. For example, if you had a column called `count`, you'd need to quote that every time you refer to it, as `COUNT()` is a function (and hence, reserved word) in MySQL.

I want to add custom field 'tnid' to all my posts, and have it's meta value taken from field 'name'
i have the following working query:
INSERT INTO wp_postmeta (post_id, meta_key, meta_value)(
SELECT post_id, 'tnid', meta_value
FROM wp_postmeta
WHERE meta_key='name')
Now to my question. I want to add the new custom field only to post_type 'post', not to any other post_type. How do i have to edit the SQL query to accomplish that? thx | Hope this below SQL query will solve your problem-
INSERT INTO wp_postmeta

'tnid',
meta_value

WHERE meta_key = 'name'
AND post_id IN (SELECT id

Set default options for inserting media
Is it possible to set default options for inserting image into article. I want every image to link to full image and be right aligned. Setting this manually every time is annoying and unproductive.
Can I do this with some hook in my functions file? | You can do this in two ways. If you want to keep it theme specific, edit your `functions.php` file with this code:
add_action( 'after_setup_theme', 'my_new_default_image_settings' );
function my_new_default_image_settings() {
update_option( 'image_default_align', 'right' );
update_option( 'image_default_link_type', 'file' );
}
The other way to do it is more general, but also more rigid:
1. Go to YOURSITE.COM/wp-admin/options.php
2. Find the `image_default_link_type` field.
3. Type in `file`.
4. Find the `image_default_align` field.
5. Type in `right`.
6. Scroll to tho bottom and hit Save.

Levels of caching and impact on the WordPress web site
Recently I have tried to answer this question and I noted how important is to understand the caching when solving Wordpress problems.
Namely, I just wanted to summarize the possible levels of caching that may exist between the web browsers and WordPress website.
There is:
* A browser caching
* Possible proxy web server caching
* WordPress plugin caching (W3TC, ...)
* Webserver software caching (Like Redis, Memcached ,...)
* WordPress query caching
* MySQL caching
* PHP opcode caching
* Maybe more
This may look complex but if I add custom version to the URL like `?version=3.14` will all possible caches be defeated? | Adding custom variables(query strings) to **static resources** doesn't affect caching at some of the levels you've listed above:
* WordPress plugin caching
* Webserver software caching
* PHP opcode caching
* MySQL caching
* WordPress query caching
* Several more etc.
All of these don't cache static resources(js, css and so on) but rather cache the output of application codes at their different applied levels.
Most Proxy Servers, CDNs and browser cache prevent caching static resources with query strings as it is a common method used for breaking cached objects so caches at the **browser cache level** for instance would be invalidated when the query strings are updated.
To my knowledge, this might be because caches of static resources are actual copies of the static files stored with the headers and references to the object's url. | stackexchange-wordpress | {

I want edit_post_link() to open in a new window/tab (target="_blank")
I'm trying to make posts as easy to edit as possible. When a person clicks on "Edit Post", the default is to open in the same window. This can be frustrating, because it's a little difficult to quickly get back to the page they clicked "Edit Post" from (the blogroll).
Obviously, they could right-click > "Open Link in New Tab" (or Command-click), but I was wondering if there's a way to add `target="_blank"` to the edit_post_link(). Is that possible? | You can adjust the link via the `edit_post_link` filter.
Here's an example where we use a simple replace since we don't have the `class` and `url` explicitly as input arguments:

{
// Add the target attribute

PHP notice coming from the WordPress core?

2) Another case might be your are using a theme which might be using Visual Composer as a third-party plugin and has some Visual Composer Addons which is not updated and still uses that `add_shortcode_param`

Overriding a parent theme folder in the child theme

Installation problems on a domain-name-less server
Is it possible to install WordPress on a public server that doesn't have a domain name configured yet? I thought I'd set it up on IP-only, and had the line `server_name _;` in my Nginx configuration. I think it's because of this that the WordPress installation dies at `wp-admin/install.php?step=2` and I see the following error in the Nginx logs:

server {
listen 80;

Custom Fields through plugin in a Custom Post Type

Giovanna | This generally happens when you don't use some fixed term in the URL for category. For example, instead of:

The setting is in `WordPress Admin` => `Settings` => `Permalinks`.
Here, either you keep `Category base` blank or write a term like `category`, `topic` etc.
However, from your source code, it looks like you placed a dot `.` in there or used a setting from **Yoast SEO** to hide the term `category` from URL.

$result->subject = $_REQUEST['name'] . " send you a message";
$result->to = "get_option('admin_email');
$result->to = "get_option('admin_email'); showing NULL | I confess that I'm slightly confused by how your sending email function loads posts into your sidebar...the code does not seem to be doing the thing that you described.
Are you loading WordPress in sendContactForm.php? Is what you've shown here the only code in sendContactForm.php?
`get_option()` is a WordPress function, so you need to load WordPress to do this. This is usually done by putting something at the top of your php file like:
`require('../../../wp-load.php');`
But that's a bit hacky.
The proper way to do AJAX in WordPress is to send your POST request to `/wp-admin/admin-ajax.php` with an parameter like `action=sendContactForm` and then create an action hook like this:
add_action('wp_ajax_sendContactForm', 'my_email_function');
add_action('wp_ajax_nopriv_sendContactForm', 'my_email_function');
function my_email_function() {
// process request here

I'm attempting to modify existing rewrite rules generated by WordPress in order to override the default rewrite rules generated.
I'm using the filter hook `rewrite_rules_array` to obtain an array of existing rewrite rules.
While sifting through the rewrite rules array, there are rewrite rules containing `$` in the array value.
After replacing a set of array key/value pairs, PHP is interpreting the suffix text of the array value containing `$` as a PHP variable.
**For example:** `&feed=$matches[1]`.
When I'm done with my modifications and dump the array, everywhere with `$matches[1]` just appears blank.
**My question is:** How can I get `&feed=$matches[1]` to output as `&feed=$matches[1]` in my array value instead of outputting like `&feed=`?
Both my array keys and array values of the modified rewrite rules are contained within double quotes. | Wow I feel like a huge newblet. This is incredibly simple. Just escape it with a `\`.
`"&feed=$matches[1]"` should be `"&feed=\$matches[1]"`.

Change Structure Permalink => Error 404? How to redirect
i have a problem with Permalink as: former, i have set Structure Permalink as: `/abc-%postname%/` now i change (remove `abc-`) and set Structure Permalink to `Post name as /%postname%/` but all my link is error 404.

Removing Facebook contact field from user contact not working
I'm trying to unset the Facebook link for users who registered in the past 365 days. For users who have completed more than a year, don't unset.
Here's my code which is not working:
function modify_user_contact_methods( $user_contact ) {
get_currentuserinfo();
$user_data = get_userdata($user_ID);
$registered_date = $user_data->user_registered;
if (strtotime($registered_date) > strtotime('-365 days')){
// Remove user contact methods
unset( $user_contact['facebook'] );
}
return $user_contact;
}
add_filter( 'user_contactmethods', 'modify_user_contact_methods' );

Please guide. | Firs things first... always, always enable debugging.

Security issue with 'paged' and 'posts_per_page' parameters taken directly from a POST request?
I was wondering if this poses any security risk:
$current_page = $_POST['page'];
$posts_per_page = $_POST['posts_per_page'];
$result = new \WP_Query([
'posts_per_page' => $posts_per_page,
'paged' => ++$current_page,
'post_type' => 'post'
]);
Since I take `posts_per_page` and `paged` directly from a POST xhr request, someone could enter whatever values they want.
I see here that `posts_per_page` and `paged` are listed as `int`, but could someone use e.g. SQL injection in this case nonetheless? | Currently we have the following typecasting in the `WP_Query` class (see here):
$q['posts_per_page'] = (int) $q['posts_per_page'];
if ( $q['posts_per_page'] < -1 )
$q['posts_per_page'] = abs($q['posts_per_page']);
elseif ( $q['posts_per_page'] == 0 )
$q['posts_per_page'] = 1;
and here:
if ( isset($q['page']) ) {
$q['page'] = trim($q['page'], '/');
$q['page'] = absint($q['page']);
}
Instead of running the query for every user input, hoping the core will handle it somewhere, **validate** it beforehand and only run the query if it's of correct type and range. You could check for a positive integer here and have a max allowed value, e.g. 100, because you don't want to allow e.g. 9999999 that could seriously slow down the whole site. | stackexchange-wordpress | {

When importing - failed to import: Invalid post type, feedback
I am attempting to import a site using XML generated by WordPress.com

'public' => true,
'labels' => [
'singular_name' => 'Feedback',
'name' => 'Feedback',

How to use $wpdb to delete in a custom table
I am having trouble finding a good resource on using the $wpdb function.
I am trying to delete a row from a custom table named: eLearning_progress
$removefromdb = $wpdb->query("DELETE FROM eLearning_progress WHERE ID = '$user_id' AND module_id = '$singlecomparearrays_remove'" );
The row I would like to delete has the ID of '$user_id' and the 'module_id' of '$singlecomparearrays_remove'.
I have also tried:
$removefromdb = $wpdb->query( "DELETE FROM eLearning_progress WHERE ID = ($user_id) AND module_id = ($singlecomparearrays_remove)" );
and then:
$removefromdb = $wpdb->query($wpdb->prepare("DELETE FROM eLearning_progress WHERE ID = %s AND module_id = %s", $user_id, $singlecomparearrays_remove));
Please try not to sigh too loudly at my attempts but I can't find a good guide on using the DELETE command with variables in there too. Any help is much appreciated.
Regards, Alex | The best WP API solution for this goal is to use the `delete()` function to remove a row.
A small example, to delete the raw `ID` in the custom table `eLearning_progress`.
$id = 0815;
$table = 'eLearning_progress';
$wpdb->delete( $table, array( 'id' => $id ) );

Dynamicaly update field created with wp_editor()

Unable to show a message after plugin activation
Based on: <
My actual code
class Activation {
function __construct() {

}
function text_admin_notices () {
?>

</div

}

I know that `__construct()` is being executed, because `Utils::update_option` (a simple wrapper) is working, it's creating the option in the option table.

WP_Query Excluding pages with Order is 0

'post_status' => 'publish',
'meta_key' => 'tile-home',
'meta_value' => 1,
'orderby' => 'menu_order',
'order' => 'ASC'

How can I edit the arguments in order (please, forgive me the pun) to exclude all the pages that have menu_order set to 0? | You can define custom `where` like this if your table is `wp_posts`
function _20170112( $where ){

'post_status' => 'publish',
'meta_key' => 'tile-home',

How to detect custom query inside `posts_where` hook?
Imagine you have something like this:
function f_posts_where( $where ){
// set a condition based on arguments ...
}
add_filter( 'posts_where', 'f_posts_where' );
What is the best way to set a condition for my custom query inside the `f_posts_where`?
I create a custom query like this:
$q = new \WP_Query( $args ); | If we have the query arguments like this
$args = array(
'queryid' => 'blackjack',
...
);
$q = new WP_Query( $args );
Note we added one custom query argument that is not officially present in here. Now we can identify the exact query by that `queryid` if we use the second parameter of the `posts_where` hook.
function f_posts_where( $where, \WP_Query $q ){
// $q->query will hold the query arguments ...
if ( 'blackjack' == $q->query['queryid'] ){
// do our custom actions on $where for our queryid blackjack
return $where.
}
return $where;
}
add_filter( 'posts_where', 'f_posts_where', 10 , 2 );
As you can note `$q->query` will hold the query arguments.
This will allow us to intercept the custom queries we like if we add custom arguments we like. In this case the `queryid`. | stackexchange-wordpress | {

How to unpublish a page and still keep a draft?
I have a holiday sale page that no longer applies as the holidays have past.
* I want to keep the page for future design reference.
* I do not want the page to be accessible from the Internet.
I tried:
* Setting the page status to `Pending Review`
* Setting the page status to `Draft`
Neither of these status changes seem to have any effect as the page is still visible at the URL. I am not even sure why these settings exist for pages.
I could password protect or set the page to private, but neither option unpublishes the page.
I could do a 301 redirect, but I would prefer not to use this method. (SEO impact of 301 redirects.)
Is there no other option? | > When I logged out the URL generated a 404.
Correct.
> Why can I see the page when logged in? Is this documented somewhere in the codex?
I think this is something that codex has but some parts are still not written, like this part for draft. In the case of **draft** post your permalink will look like this:
?p=2898&preview=true
And it is not available when you are not logged out as you noted -- _404 error page_ is what you will get.
The same error you will get also for the **pending review** status when you are not logged in, but the permalink will be the same as for the **published** post if you are logged in. | stackexchange-wordpress | {

Identifying where plugins are being used in your wordpress install
I've inherited an existing wordpress installation and there are several plugins (active and inactive) that I'm unfamiliar with and unsure if they're even still being used in any fashion. Once I see that they're not being used at all, I plan to delete them.
Do you have any tips or ways to automatically test if any content using these plugins (and if so, identifying where), without deactivating each, one by one, and examining different pages or the dashboard?
I'm thinking something like searching for plugins' shortcode(s) in my posts tables? | This would be impractically to automate due to nearly endless amount of ways which constitute plugin "use". What plugins do range from super obvious to extremely subtle and niche.
Some plugins specialize in changing behavior to _not_ do something, making their functionality consist of _absence_ rather than presence of results.
If I absolutely _needed_ a starting point I would dump `get_included_files()` and check against plugin folders to have a rough guess which stuff is actively loaded. But that would only serve as rough outlook.

Delay the ping to Google when publishing new Posts or Pages

How to get all Custom Post Type Filtered by one Specific Taxonomy Term

Where `genre` is the name of your taxonomy ( not the human readable version, but the internal slug ), and `comedy` is the slug of the term you want to filter by
Importantly, indent your query parameters, and put them each on their own line so that it's easy to read/type/change, a good editor will do this for you. You also need to do an `if( $loop->have_posts() )` to check that you got posts and handle things if none were found, and a `wp_reset_postdata` call to clean up at the end ( otherwise any calls you make will show the last movie in the loop, rather than the current post/page )
