Why doesn't this function work when I know that the IP Address is "true"?
I am trying to append "DEV SRV:" to the page title (i.e. title tag) if the IP Address matches that of the dev server. I have tried this both in the functions.php file of my child theme and as a standalone plugin
add_filter('wp_title', 'dev_srv_title');
function dev_srv_title($title) {
$host = $_SERVER['SERVER_ADDR'];
if ($host =='0.0.0.0') {
return 'DEV SRV: '.$title;
}
return $title;
} | The issue was not persistent between multiple installations because there were multiple themes in use. The themes were creating the title tag in different ways.
Changed plugin based solution to inserting conditional banner content (and later a contextual feedback form) in wp_footer which is working regardless of theme (so far ) | stackexchange-wordpress | {

Random users always showing same 8 users
I am trying to display some random users on the page. It is changing the order of the users it is showing, but it is only showing the same users instead of randomizing from all users in the database.
So, it is currently showing 8 users, but always the same users, just in a different order. I have 100 users and it shouldn't always just show the same 8.
<?php $args = array(
'role__in' => array( 'member' ),
'exclude' => array( 37, 1 ),
'orderby' => 'rand'
);
$wp_user_query = new WP_User_Query($args);
$members = $wp_user_query->get_results();
?> | Actually, `rand` is not a valid argument for `orderby` in the WP_User_Query class (it is in the WP-Query class). So, it should default to `user_login`, giving you an alphabetical list. Also, you should get all users that fit the `member` and `exclude` criteria from this query, not just eight.
This suggests there is other code interfering with yours.
My suggestion would be to start with adding `'number' => 100` to `$args`. That should overrule any other code limiting the amount of results. You could then use `shuffle` to randomize the array returned or pick some random elements from the array with `array_rand`. | stackexchange-wordpress | {

Wordpress REST API V2: how to get list of all posts?
I need to get a list of all posts in a certain category. The number of posts is more than 100. I do not need the post's content. I need only id and slug.
` returns only 10 posts with content.
Is it possible to get all posts without content? | Out of the box and using the core available hooks and API, **you can't have more than 100 items per response on WordPress REST API** for performance reasons. For the second part of the question, _you may remove some fields from the response_ by using `_fields` parameter in your request as you can see in the examples of the handbook:
// option a: using comma separated fields names.
// option b: using array syntax.
And theoretically if you own the website, you could remove fields from the API response by using the `rest_prepare_{$this->post_type}` dynamic filter for the post(s) type(s) you want to change.
if(!function_exists('wpse_382314_post_filter_data')) :
function wpse_382314_post_filter_data($response, $post) {
$response->data['post_title'] = '';
$response->data['post_content'] = '';

If two first numbers exist in wp_meta_query value

Giving a new page an existing URL
Say I want to build a new page which will eventually replace an existing page. Rather then editing the existing page, I want to take my time and get it right, but when the new page is ready, I want it to have the URL of the original page.
How do I do that please? Presumably if I edit the just permalink to be the same as the exiting page, there will be two pages with the same permalink, which will cause problems? | The process to do this isn't probably as complex as you think.
1. Leave the existing page exactly as-is. Don't change its slug etc.
2. Create a new page draft
3. Create the new page content as you'd like it to have.
4. Once the new page is complete, and ready to go, go back to the original page and change its slug to _anything else_. (see below gif #1)
5. Go to the new page, and set its slug to the **original page slug** (that you changed in step #4)
6. Publish the new page.
.
If you want to keep the old page, decide on the slug you'd like to have and update it as necessary. | stackexchange-wordpress | {

Load user by specific role

array_keys( wp_roles()->get_names() ),

How to export posts and keep html tags in the title

How Can I save multiple records in same meta key?

For example:
dates(meta key) 2(meta value)
dates(meta key) 3(meta value)
dates(meta key) 4(meta value) | This should work out of the box, as long as the "unique" parameter of `add_post_meta()` is `false`.
add_post_meta($id, '_dates', 2, false);
add_post_meta($id, '_dates', 3, false);
add_post_meta($id, '_dates', 4, false);
then somewhere else
$dates = get_post_meta($id, '_dates', false);

Help! ERROR: Cookies are blocked due to unexpected output on attempting to login to resolve an issue with my site
First-timer over here!
**Domain for the buggered website (you'll see what I mean!)** <
**URL I am using to try to login to WordPress backend to fix the issue** <
So, when I enter my username, password and then proceed to login, I get the following error message **" ERROR: Cookies are blocked due to unexpected output"**
![enter image description here](
The problem I have is that in order to resolve the issue in the first place I would need to login, but as you can see I'm in a bit of a loophole.
Can anyone offer, in as simple terms as possible, any advice on how to get around this, as currently, anyone visiting the site would most likely move onto something that doesn't look like a piece of $hit. I'm planning on closing the site down as covid has dried up that little avenue of pleasure. Onto another project that is more pandemic proof!
Many many thanks in advance | The "unexpected output" forces PHP to send HTTP headers right before the output is sent, and that's too early for WordPress, which can't send cookies later as they are HTTP headers too.
If you look at your site, you get a bunch of notices at the top, which means you have something like …
define( 'WP_DEBUG', true );
… in your `wp-config.php`. You should _never_ set that to `true` on a live site.
So how to fix it? Two steps:
1. Access your site per FTP or SSH, and edit the `wp-config.php`, so `WP_DEBUG` is set to `false`.
2. Then log in, and update WordPress. Newer versions won't have this problem. | stackexchange-wordpress | {

How to tell which one of my plugins are paid or free?
I'm new to working on a specific WordPress site that has over 50 plugins installed.

That could be one of the clues.
One obvious clue would be that the plugin has some kind of login/licence key system.

if ( 'post' === get_post_type( $post ) ) {

What is the best way to achieve this. I think a plugin, but then how would I position the plugin at a place on an already existing page?
Sorry if this is a noob question, I really want to understand the correct way to achieve this before starting. | A plugin is just a file that gets loaded into WordPress, it doesn't have a _location_ on the page. In fact WordPress doesn't know which page it is yet when plugins are loaded. It may not even be a frontend page!
So if a plugin is just a place to put code such as hooks and filters, how do you embed code in a page?
There are several methods:
* blocks
* shortcodes
* widgets
* theme template files
You can register blocks/shortcodes/widgets in a plugin, whereas templates files are theme specific.

How to create a post using REST API with sending data as a JSON body?
I am able to create posts on my WordPress website using it's REST API with the below curl request format. Website uses basic auth plugin for the authentication process.
`curl --user "username:password" -X POST -i
However, my problem is I need to set custom fields of the post when creating a post using REST API. I tried to send data as a JSON body using the below command and it didn't work. It just returns all the posts without creating a new post and also without giving any error.
`curl --user "username:password" -X POST -i -d '{"title":"NEw tiitle"}'`
I have tried sending post creation requests to my website using the Postman service also and the same thing happened. Could anyone please help me to solve this problem? Thanks in advance! | That's strange, but nonetheless, you should know that whether you use cURL, PHP, JS, etc., if you're sending a JSON data, then you should set the `Content-Type` _header_ to `application/json`.
And via the cURL command line, you can use the `-H` option:
curl --user "username:password" -X POST \
-H "Content-Type: application/json" \
-i \
-d '{"title": "foo bar", "content": "test"}'
Also, if you're using Windows, you may need to use the **double quotes** instead of single quotes with the `-d` option. So the above would be: ( note I used the caret (`^`) symbol and not backslash )
curl --user "username:password" -X POST ^
-H "Content-Type: application/json" ^
-i ^
-d "{\"title\": \"Windows test\", \"content\": \"test\"}" | stackexchange-wordpress | {

Use object in template part
I try to use a template part in my loop.
<?php
foreach ($categories as $category) {
get_template_part( 'temp-parts/loop/blcnr_loop');
}
?>
In the template part I call the object
<?php
echo $category->name;
?>
But this gives me an error " **Trying to get property 'name' of non-object** ". Is there a solution for this?
I tried this
foreach ($categories as $category) {
$categoryData = array(
'name' => 'theName'
);
get_template_part( 'temp-parts/loop/blcnr_loop', NULL, $categoryData);
}
And this in the template part
echo $categoryData['name'];`
But this returns NULL | As of WordPress 5.5 you can pass variables to template parts by passing them in an array to the third argument of `get_template_part()`:
foreach ($categories as $category) {
get_template_part( 'temp-parts/loop/blcnr_loop', null, [ 'category' => $category ] );
}
These variables will populate an `$args` variable accessible from the the template:

Apply function.php filter only if url not has /amp/
I applied a filter to remove theme styles and javascript in function.php, but I want this to happen only if the url not ends with /amp/ | What is `amp`? Is it tag or category or page? You should use standard wordpress functions like `is_page()` `is_category()` `is_tag()`.
You can also use `$wp->request`. It will return the request URI. If the address is `" it will return `slug1/slug2` then use `explode()` function to split it.
<?php $uri = $wp->request;
$slugs = explode("/",$uri);//variable $slugs will have array of slugs
//$slugs[count($slugs)-1] will return last slug
if($slugs[count($slugs)-1] != "amp") {
//Apply your filter filter here
}

Can WP plugins access files outside the installation folder?
If I have multiple WP installations in let's say /var/www. Can a plugin be developed to access files outside its own directory?
I want to host multiple installations for different customers in the same chroot. But those customers will have admin access to their instance. Can they theoretically develop a WP plugin to access the files (or even WP config, including DB credentials) of another WP installation?
For example, can the WP located at /var/www/wordpress-customer-1 access files located at /var/www/wordpress-customer-2 ?
Thanks! | > Can they theoretically develop a WP plugin to access the files (or even WP config, including DB credentials) of another WP installation?
Yes.
If your folders are owned by the same user, run as the same user in Apache/Nginx or have read/write access to each other, then it's possible.
Your installations are sandboxed at the server/host level, not the WP level.If your users have the ability to upload plugins or edit PHP, then they can easily upload a version of the `emergency.php` targeted at the other installs and reset the admin password. Likewise they could insert a PHP shell, or read the `wp-config.php` of the other install.
It's also much worse, if one of those sites gets hacked, all of them could be infected. You also have a more difficult time with backups
If you are concerned for security, you should fix this immediately. How you would fix that is server specific and not in the scope of this site. Consider asking on ServerFault | stackexchange-wordpress | {

Filter Post Title without affecting screen-reader-text
Let's consider this code:
add_filter('the_title', static function ($title) {
return $title. '-boom';
});
Works fine, and adds '-boom' near all the titles.
But, I also noticed that in some themes (Twenty Twenty, Twenty One and most likely many others) if a post contains the `<!--more-->` tag, this also affect the "continue reading" button, see image attached
![enter image description here](
As you can see the span class "screen reader text" is also affected. Since I want to add some html close to the_title, this breaks the layout.
How to solve? | Ok, I found a solution.
I've found the filter `excerpt_more` that is used to show the string shown within the more link (if theme use standard WP functions).
So, to achieve this, we need to hook the `excerpt_more` and use a lower priority of the one used by the theme.
In my example, this
add_filter('the_title', static function ($title) {
return $title. '-boom';
});
adds `-boom` string in both text and excpert, and this
add_filter('excerpt_more', function ($more_link_element) {
$more_link_element = str_replace('-boom', '', $more_link_element);
return $more_link_element;

WP CLI Get all Enqueued Scripts and Styles
Normally, I would hook into the `wp_enqueue_scripts` action in order to gather a list of enqueue'd scripts and styles.
However, I have a very intensive process I need to run, thus instead of running it through the site itself, I am hooking into WP CLI.
How can I gather the scripts and styles without having the action `wp_enqueue_scripts` available to me in CLI? Or is there a CLI action that I am just not finding in the documentation for the WP CLI API? | You can't, and it doesn't make sense to do so.
Different pages/URLs enqueue different things, e.g. a WP Admin page won't enqueue the same styles and scripts, widgets might enqueue things conditionally, etc.
But in WP CLI those hooks don't run, and there is no page or frontend. So the question doesn't make sense at a fundamental level. It isn't enough to know the URL either, **you need to render the page to know which scripts and styles are enqueued**. There is no way to know in advance.
Could you render the page in WP CLI? _Unlikely_ , a CLI environment will be missing a lot of the environment that a browser request has. For example, there is no URL, no GET/POST, no current user, cookies, etc.
The closest you can get to this, is a `curl` request. Just know that the security policy you generate will be specific to that page, and will be missing other scripts and styles, e.g. things only enqueued for admins/logged in users/other pages/etc. | stackexchange-wordpress | {

Check If Post Was Published More Than 6 Months Ago Using get_the_date

So you can use that 3rd parameter and set the `orderby` to `taxonomy` (and `order` to `ASC`) like so:
$workshop_terms = wp_get_object_terms( $post->ID, array( 'area', 'group' ), array(
'orderby' => 'taxonomy',
'order' => 'ASC',
) );

How would you add sequentially numbered labels to images in posts?
I'd like to add sequentially numbered labels to images in posts. Just a small number in the corner of each image to help when referencing them in my writing.
All of the images are wp-block-image (no galleries). The numbering should be simple +1 addition **based on the order of appearance** in the images for that post (top left = #1, next img = #2...)
The order isn't expected to change after the post is published - it's static content - but in draft stage the images are moved and will be out of order from their upload/inserted/filename/ID.
A few gallery plugins appeared in search that claim to have this feature, but I don't think they'll work with wp-block-images and my existing content. And I'd rather not use a plugin if it can be handled cleaner without it.
How would you add these labels correctly and efficiently? | No need for plugins or any change to the markup - you can do all of this in pure CSS with what is called counters, which do have broad browser support.
body {
counter-reset: imageLabel;
}
.wp-block-image::before {
counter-increment: imageLabel;
content: "#" counter(imageLabel);
}
This will already produce the number after the image, you can style the `::before` however you like and position it where it needs to be.
Beware that this might hurt the accessibility of the page, I'm unsure how well screen readers can interact with both `::before` and the CSS `content`. However, solving this will probably require you to create either a new block or edit the image block . | stackexchange-wordpress | {

WordPress Admin bar missing from custom theme

* Your host is adding them, possibly as a condition of a cheap/free hosting plan.
* You installed a pirated theme or plugin that contains malicious code.
* Your website has been hacked in some other way. This seems unlikely if you saw them right after installing.
* _You_ have been hacked, and you have malware on your computer that's displaying ads on web pages.

How to make custom total price reactive in navigation
I created navigation for my custom template and added total price inside the `<li></li>` elements and it show the price if I add product to the cart, but if I add another product to cart price not change automatically. If I want the price updated, I need to refresh the whole page.
Can someone help me to make this price updating automatically if I add products to cart? I'm very bad about ajax etc... but I want this to working like it should work.
<ul class="nav-link-right">
<li class="nav-link-price">
<?php if ( class_exists( 'Woocommerce' ) ) : ?>
<?php
// Get order total
$cart_total = WC()->cart->get_cart_subtotal();
?>
<span id="order-total-price"><?php echo $cart_total; ?></span>
</li>
</ul> | Using woocommerce `woocommerce_add_to_cart_fragments` filter you can do that.
Going by the `id` attribute that you currently have for the span that displays the cart total, you can use the following code
add_filter('woocommerce_add_to_cart_fragments', 'bt_update_cart_total');
function bt_update_cart_total ($fragments) {
$fragments['#order-total-price'] = '<span id="order-total-price">' . WC()->cart->get_cart_subtotal() . '</span>';
return $fragments;
}

Removing extra large generated images disables all crops

Using wp_editor tinyMCE in metabox cause form alert on leaving page

How to hook code in <body>?
In the question How to add code to Header.php in a child theme?, a recommended solution is to create a plugin, then hook into `wp_head` action by using this code:
add_action('wp_head', 'wpse_43672_wp_head');
function wpse_43672_wp_head(){
//Close PHP tags
?>
ADD YOUR PLAIN HTML CODE HERE
<?php //Open PHP tags
}
Looking at header.php, I see that `<?php wp_head(); ?>` belongs to `<head>`, not `<body>`. So which function to use if I want to hook into the body? I don't see any `<?php wp_body(); ?>` in header.php, though I find there is `<?php wp_footer(); ?>` right before `</body>` in footer.php.
My goal is to add these code, in order to use the Off Canvas Sidebars plugin:
<body>
<?php do_action('website_before'); ?>
<!-- WEBSITE CONTENT -->
<?php do_action('website_after'); ?>
<?php wp_footer(); ?>
</body> | The action you are looking for is `wp_body_open()`. I do not know if you are writing your own theme or not but if you are using a pre-built theme, the author of your theme may not have included this support.
If properly supported in your theme, any function hooked to this action will be called immediately after the page opening `<body>` element.

Best way to trigger rewrite rules
I typically call the rewrite rules with this action
add_action('init', 'add_my_rewrite_rules')
But what I do not like about it is that the rewrite rules are written every time an `init` action is triggered, which means pretty much every time a page is refreshed.
Is this the correct action to call the rewrite rules? Is there a better way of handling that? (i.e, no need to add the rules every time we trigger `init`)
Thanks. | `init` is the recommended hook and no, the rewrite rules will not be overwritten each time the hook fires or that the page is loaded, _unless_ if you call `flush_rewrite_rules()` or `WP_Rewrite::flush_rules()` in your callback.
add_action( 'init', 'add_my_rewrite_rules' );
function add_my_rewrite_rules() {
add_rewrite_rule( ... );
flush_rewrite_rules(); // don't do this
}
So please don't do that, or do it only upon plugin/theme activation and deactivation — and if you don't already know, you can easily flush the rules by simply going to the Permalink settings admin page, without having to hit the Save Changes button. | stackexchange-wordpress | {

$var_a = filter_input( INPUT_POST, 'var_a', FILTER_SANITIZE_STRING );
The above code will get `var_a` out of the `$_POST` data, and sanitize according to PHP's `FILTER_SANITIZE_STRING`. You can read the PHP Manual on Types of filters for other data types. | stackexchange-wordpress | {

How to control ajax calls without effecting memory of server?
I am trying to understand how ajax call and memory of server are linked? Is there any parameter in WordPress control this.
Say if am importing something big using ajax how can perform that without effecting the server with a memory limit of 250MB?
Pls help | An AJAX request to your server is no different to any other PHP request the server might handle, e.g. the frontend.
Browser requests have a time and memory limit configured at the server level, _WordPress itself is not responsible for setting or enforcing those limits._
> Say if am importing something big using ajax how can perform that without effecting the server with a memory limit of 250MB?
You have the following options:
1. Use less memory
2. Don't process the entire import in a single request
3. Break your import file into smaller chunks that get processed separately
4. Do the processing elsewhere, e.g. a CLI task. PHP running from a CLI command has no upper limit on time or memory except the amount of physical memory installed on the server.
Otherwise, you can't do stuff for free, there is always a cost. Browser requests are not suited to long running expensive/heavy tasks. | stackexchange-wordpress | {

What theme does this website use?
see <
Does anybody know the theme this site uses? Or, this site is not using wordpress? In this case, can you tell me what CMS/framework the site is built with?
Thanks | Looks like WP - BuiltWith shows Wordpress and Elementor as of Feb 2020, and Elementor classes are visible via inspector
There's no way to see which theme it is (afaik), but it's using Elementor, so it probably wouldn't matter which theme it uses if you're just looking to emulate its appearance.
Also worth noting that even when you use the same theme as another site, there are a million different ways in which a theme can be customized, so going for same/same is generally an exercise in futility.

Overwrite tpl-footer.php in child
I am trying to overwrite a template file (tpl-footer.php) in my child-theme. According to the wordpress docs this should be possible just by adding the file with the same name and the same path into the child-theme. When I do so, nothing happens.
The theme I use is **snsnitan**
Does anyone know what I am missing? Do I need to overwrite more files?
The footer.php in parent theme has just:
<?php wp_footer(); ?>
</body></html> | **If the file is included via`get_template_part` or a part of the template hierarchy, then yes**, create a file with the same name in a child theme and WordPress will preferentially load that file.
**If the file is included via`include`/`require`, then no**, those are PHP language features, not WordPress functions, there is no way to intercept or override them so that your file is loaded instead. Either fork the theme or contact the theme support route. The author may have provided alternative methods of overriding the template, or be able to add support for it.
Remember, child themes let you preferentially load child theme templates via the template hierarchy and `get_template_part`. They can't auto-replace arbitrary PHP files, CSS, JS etc files by putting them in a child theme and expecting them to be used instead | stackexchange-wordpress | {

htaccess redirect not working
I'd like to 301 redirect all `.com/language/X` URLs to `.com/members/?members_search=X`.
Test case:
` should 301 redirect to
`
The rule I have set up:
RedirectMatch 301 "^/language/(.*)" "/members/?members_search=$1"
It works correctly when I use a `.htaccess` tester. The rule is at the very top of the `.htaccess` file. Any ideas? | Even though you've placed this rule at the top of the `.htaccess` file, `RedirectMatch` is a mod_alias directive so still runs _after_ other mod_rewrite (ie. `RewriteRule`) directives, so you may have a conflict.
Try changing this to a mod_rewrite directive. For example:
RewriteRule ^language/(.*) /members/?members_search=$1 [R=301,L]
NB: No slash prefix on the `RewriteRule` _pattern_ when used inside `.htaccess` files.
You will likely need to clear your browser cache before testing. Preferably test with 302 (temporary) redirects to avoid potential caching issues. | stackexchange-wordpress | {

What is the reason for the new_to_publish hook not working?
this hook should normally be triggered on new post but it doesn't work
add_action("new_to_publish", "doSomething", 10,1);
function doSomething($post){
global $post;
$_SESSION['yeni'] = 'test';
}
echo $_SESSION['yeni']; | When you create a new post, the initial post status is not `new`, but rather `auto-draft`. Try this:
add_action("draft_to_publish", "doSomething", 10,1);
function doSomething($post){

$_SESSION['yeni'] = 'test';
}
echo $_SESSION['yeni'];
Also note that you may want to make sure your session is properly initialized. To verify the callback works at least, enable `WP_DEBUG` and `WP_DEBUG_LOG` and do something like
add_action("draft_to_publish", "doSomething", 10,1);
function doSomething($post){
error_log( 'Inside the new post transition');

About template hierarchy
The hierarchy picture doesn't tell me exactly which one is dominant.
/search/query/?category_name=general&post_type=custom
/category/general/?s=query
/tag/any/?s=query
/custom_post/?s=query&custom_tax=term
/?s=query&custom_tax=term&post_type=custom
When I tested the links I gave above, I could not draw any conclusions. When we open these links, I do not understand which archive file it prefers.
Sometimes it goes to `archive.php` while opening `search.php` in some cases.
Outside of this hierarchy, is there any indication of what it prefers when it comes to equivalence? | The answer is simple:
* `/search/query/?category_name=general&post_type=custom` is not a part of WordPress and has been added by a plugin/theme, you need to ask their support or inspect the code to find out
For everything else, if `is_search()` is true, then it's a search archive. If `is_search()` is not true it is not a search archive.
Since all of those URLs have `?s=` they are all searching for things, so they are all search archives.
We know this because it shows `search.php`, and because the body class is:
class="archive search search-results category category-maintenance category-39 logged-in admin-bar customize-support"
You shouldn't need to know the priority of template to know which template is currently loaded. WordPress shares this information openly if you built the theme correctly, debugging tools will tell you, and you can always put **this is the search template** at the top of `search.php` and see if the text appears. | stackexchange-wordpress | {

Don’t edit core WordPress files or the files of themes or plugins you didn’t develop yourself. If those are updated they are replaced entirely and you will lose any changes you make.

PHP variable = get_the_post_thumbnail_url outputting without slashes

RSS audio enclosures have length of zero (podcast duration is missing)
I have had success at creating an RSS feed with enclosures containing episodes of my podcast by simply creating a post and inserting an mp3 file from my media library into it via the robust `Add Media` functionality of the post editor.

<enclosure url=" length="0" type="audio/mpeg" />

I am not interested in changing the format of my posts, so any plugin-based solution should not require a significantly different workflow when posting. | The enclosure tag will implement via the function `rss_enclosure`.

Set WordPress Transient Expiration via Variable Value
I want to set WordPress Transient via Variable Value.
This is an example code with what I'm trying to achieve.
<?php
if ( false === get_transient( 'special_query_results' ) ) {
$ExpiryInterval = "24 * HOUR_IN_SECONDS"; // <--- Storing in Variable
$RandPostQuery = new WP_Query(array('post_type'=>array('tip'),'posts_per_page' => 1,'orderby'=>'rand'));
set_transient( 'special_query_results', $RandPostQuery , $ExpiryInterval ); // <-- Retriving from Variable
}
?>
I don't know why it's not working. If I try setting directly without variable it's working perfectly. Not sure why it's not working this way. | $ExpiryInterval = "24 * HOUR_IN_SECONDS";
`$ExpiryInterval` is being assigned a string, but you need a number.
Consider this example:
$foo = 5 * 10;
$bar = "5 * 10";
The value of `$foo` is `50`. The value of `$bar` is `"5 * 10"`. `set_transient` expects a number, not a string, `"24 * HOUR_IN_SECONDS"` is text/string, `24 * HOUR_IN_SECONDS` is a number. `HOUR_IN_SECONDS` is a constant equal to the number of seconds in an hour. | stackexchange-wordpress | {

How to add CSS via custom plugin?

}

wp_enqueue_style( 'style', get_stylesheet_uri() );
wp_enqueue_style( 'slider', get_template_directory_uri() . 'test.css', array(), '1.1', 'all');
Neither of those files are in your theme. `get_stylesheet_uri` refers to the `style.css` that has the themes name etc, and `get_template_directory_uri` is the URL of the parent theme. Neither of those are your plugin folder.
_You can confirm this by looking at the browser dev tools and seeing an error in the console that it tried to load a`test.css` from your themes folder and failed._
Instead use `plugins_url`.
e.g.
plugins_url( 'images/wordpress.png', __FILE__ )
Where the first parameter is the path to the file in your plugin folder, and the second parameter is the main plugin file location on the server.
So this:
get_template_directory_uri() . 'test.css'
becomes:
plugins_url( 'test.css', __FILE__ ); | stackexchange-wordpress | {

From 3.5 to 5.6.2 - Recommendation on how to get there with the least amount of pain?
I've recently been asked to help someone who's neglected their WordPress for a long time. They're currently on 3.5. I need to get them current. I'm considering the following options:
1. Manually upgrade step-by-step. Outside of the pain of more than 20 steps, I'll also likely need to upgrade plugins when the old version no longer works with the next WP version.
2. Export the site contents using the WP export, then re-import the content. I've got a few plugins that won't export (and I'm not sure I want to deal with import/export of them from the database directly).

Evaluate if the website really needs the features and functionality the plugins provide. If so, add them progressively later.

else
