Audio file's length (duration) is missing from Attachment Details in Media Library
I'm uploading a different mp3 file to each post as an attachment and using `wp_get_attachment_metadata()` to print the duration of the mp3 file.

Best way to include reusable sections in page content
I'm fairly new to WP dev and I'm trying to work out the best method to include reusable sections/templates within the page content added within the page editor. I have included an image to illustrate what I mean:
 for each reusable section, then create shortcode functions for them in the functions.php. Then add them to the page content using shortcodes?
Hope this makes sense.
Thanks | I think you should to take a look at the gutenberg bloc.
This is not simple at the first approach, but I think you should take a look at it (even if you want to use some plugin to help you)

What plugins create a directory on the root directory of WordPress?
How can I detect if a plugin or a program is creating a folder on the root directory of my WordPress site?

How to test a Wordpress plugin in real time
I'm developing a simple WordPress plugin, and each time I want to test the plugin manually, I need to make a zip file and upload it to the site through the admin panel. (The WordPress site is running locally through XAMPP) It's very tedious to do this every time I make a change.
Is there any way to test the changes to my plugin in real-time as I code? Helpful answers are highly appreciated. | If you use a local dev environment you can run WordPress and your plugin on your computer, any changes you make are instant as there is no uploading/installation step.
**Since you are already using XAMPP** , open the files directly with your editor from the XAMPP folder that contains the WordPress install. There is no need to upload and install as everything is on the same computer. | stackexchange-wordpress | {

Does size of a theme's functions.php file matter?
I created a custom theme for my website and I'm in the process of updating the theme to work with Gutenberg. So far the file size of the theme's functions.php file is currently 1.9MBs.

Why nav_menu_css_class doesn't work with apply_filters?
I was trying to add css class to nav items.
The documented function call in WordPress docs was
apply_filters( 'nav_menu_css_class', string[] $classes, WP_Post $item, stdClass $args, int $depth )
But I tried adding the following to functions.php in my child theme doesn't work.
apply_filters('nav_menu_css_class', ['nav-item']);
But the adding the following to functions.php works as expected.
add_filter('nav_menu_css_class', fn () => ['nav-item']);
Why do add_filter works but not apply_filters? | Because that's not what `apply_filters()` does. You'll even see the usage guide and examples at your link all use `add_filter()`. Also see the official docs on Filters.
Using `apply_filters()` makes a value filterable. `add_filter()` is used to filter a filterable value by passing a function that does the filtering.
_WordPress_ uses `apply_filters('nav_menu_css_class', ...`, which allows you to use `add_filter()` to modify its value. So if you want to modify the nav menu CSS classes, you need to add a filter, with `add_filter()`.
The reason `apply_filters()` is shown in the docs you linked is because it's showing how that filter was originally defined. Not how to use it. | stackexchange-wordpress | {

How to Extend login session times to a Month
How can I extend wordpress login sessions to a month so that it doesn’t automatically ask for login after 48 hours?
I am basically testing some program with wordpress and around 48 hours it fails and I’m pretty sure it has to do with the session id... So please help me extend it to at least a month! | By default the login cookie lasts for
* 14 days if you tick 'remember me'
* 48 hours if you don't
So as a short term fix you probably want to tick 'remember me', and to extend that to 30 days you can add an auth_cookie_expiration filter e.g.
function auth_cookie_expiration_30_days( $seconds, $user_id, $remember_me ) {
if ( $remember_me ) {
return 30 * DAY_IN_SECONDS;
}
return $seconds;
}
add_filter( 'auth_cookie_expiration', 'auth_cookie_expiration_30_days', 10, 3 );

Add a second role when registering programmatically

$new_user->add_role( 'a_second_role' );

Is it unsafe to put php in the /wp-content/uploads directory?
Pretty straight forward question, but I'll provide any clarifications needed.
The reason I'm asking is this: I created a child theme that pulls in a `custom-functions.php` file. This allows devs to customize the site without editing the child theme. I know that's the purpose of a child theme, but for the sake of brevity I won't go into the reasoning behind all that.
I put `custom-functions.php` in `/wp-content/uploads/customizations`. Is this a security risk? And if so, what's a better place to put it. I don't want to put it in my child theme because it'll get overwritten when the theme is updated. | **Yes it is unsafe** , though not for the reasons you think. _**DO NOT DO THIS.**_
If your developers can upload a PHP file to your site that gets executed, then that PHP file can undo all other security measures that you put in place. The location of the file is irrelevant. Functionally, there is no difference from editing plugins directly.
Additionally, a common security enhancement is to prevent PHP execution in the uploads folder, and assume any PHP in the uploads folder is malicious.
Either way, your proposed development process is _highly unusual_ and problematic. **I strongly advise against this.** Moving the files uploaded to another folder will not improve security.
Do not let developers upload PHP to the uploads folder. It is not a good idea. | stackexchange-wordpress | {

Super admin access to a forgotten WP instance?
I have inherited a Wordpress instance backed by a MySQL database, hosted on a bare bones server. I have SSH access to the server, and I can even log in with an old set of credentials to the admin panel. But the login I have does not allow me to install plugins, which I now must do.
Given I have the keys to the kingdom, but no knowledge, how can I either find the login for the old super admin or convert the user I can log in as into a super admin?
I'm comfortable with raw SQL, I'm just not familiar with Wordpress at all. | **Note:** Super Admins only have meaning in WordPress Multisite. I've assumed below that you're running Multisite, though your question isn't tagged as such.
Super Admins are stored as a serialized array in the `{$prefix}_sitemeta` table in the `site_admins` record. In my local installation, with only the user ID `adminpj` as a Super Admin, here's what I see:
mysql> SELECT meta_key, meta_value FROM wp_sitemeta WHERE meta_key='site_admins';
+-------------+--------------------------+
| meta_key | meta_value |
+-------------+--------------------------+
| site_admins | a:1:{i:0;s:7:"adminpj";} |
+-------------+--------------------------+
Unserializing the `meta_value`, I get:
Array (
[0] => adminpj
)

Get the term for an taxonomy archive when the term has no posts
Seems like it should be simple (the Stack Overflow catchphrase)
A taxonomy archive `taxonomy-my-taxonomy.php`, I'm using ` $terms = get_the_terms($post->ID, 'my-taxonomy');` to get the properties of the archive term.
Trouble is this is the post term(s) not the archive term.
It assumes that `$post->ID` exists, ie this taxonomy has posts. I would like to display the page with the various term properties even if it's empty.
How? | You could simply check if a post exists. Otherwise, you can get the currently viewed term:
// Check if we have posts to work with
if( ! have_posts() ) {
$term = get_queried_object(); // Get the current term
}
// Check if we have a term to work with
if( ! empty( $term ) ) {
echo $term->name; // Output term properties
}
Since you're using this in a taxonomy template, `get_queried_object()` should return a WP_Term object. | stackexchange-wordpress | {

What is an equivalent of single_cat_title for getting the slug of the category?
I searched for something like `single_cat_slug` but I did not find something relevant. All I don't know how to do it is to find the slug, not the name, of the currently opened category page. I do not know how to find the slug if I have the name.
<?php
$c = is_category();
$d = !empty(get_the_category());
$cat = $c ? single_cat_title('', false) :
( $d ? get_the_category()[0]->slug : NULL );
if ($cat !== NULL) {
?>
and after this there is some HTML in which I will use $cat to highlight the currently opened category (either a post in that category or a category archive page itself).
The issue in my case is that `single_cat_title` does not return the slug but the title (the name). | On a category archive page, you can use `get_queried_object()` to get the data of the current category in the main request, and get the slug like so: `get_queried_object()->slug`. | stackexchange-wordpress | {

current_user_can() causing critical error
I am writing a function to add a link to the Media Library in the admin menu on front end:

// add Media Library to admin menu
$wp_admin_bar->add_menu( array(

// restrict to only users who can upload media
if ( !current_user_can( 'upload_files' ) ) {
add_action( 'admin_bar_menu', 'add_media_link_to_admin_menu', 999 );
}
Without the "if ( !current_user_can( 'upload_files' ) ) {" the function works fine. But with the if statement, I get a critical error.
Am I missing something? I just want to check if user can upload files. If not, they don't need the Media Library link.
Thanks, Chris | The problem is that wp_get_current_user (which current_user_can relies upon) is pluggable, which means it isn't loaded until after plugins are loaded (to give plugins a chance to override it). That means it's not available to call from the top level of a plugin file.
Instead, I'd make the role check inside the hook e.g.
function add_media_link_to_admin_menu( $wp_admin_bar ) {
if ( current_user_can( 'upload_files' ) ) {
// add Media Library to admin menu
$wp_admin_bar->add_menu(array(
'parent' => 'appearance',
'id' => 'media-library',
'title' => 'Media Library',
'href' => '/wp-admin/upload.php',
));
}
}
add_action( 'admin_bar_menu', 'add_media_link_to_admin_menu', 999 );

Double domain name in category URL-s
My site runs on the latest version of WordPress. However, I have a problem with categories. Permalinks are set correctly and my category path looks like this: `example.com/category-name`.

I feel like I've tried everything to fix it. "siteurl" and "home" fields in the database are set correctly (` as well as permalinks. It's not plugin nor theme related - I checked everything.
Does anyone have any ideas how to fix this? | You can "workaround" the issue with a redirect in `.htaccess`, although it's not clear why this double-domain-URL would be accessible in the first place.
So, we can redirect URLs of the form `example.com/example.com/?cat=6` to `example.com/?cat=6`, which you then say is correctly redirected to `example.com/category` by WordPress.
For example, at the top of your `.htaccess` file:
RewriteRule ^(?:www\.)?example\.com/(.*) /$1 [R=301,L]
This basically removes `example.com` (or `www.example.com`) from the start of the URL-path. Any query string that was present on the initial request (eg. `cat=6`) is passed through to the target URL by default.

Input sanitation
I have a question regarding a wordpress site I have recently developed for a client. I have only until now developed a site for small clients that just require personal websites, however this client has asked me to redeveloped his site as the current one has alot of security issues. Anyway I have created the site and shown it to him and he has asked if I can 'apply input sanitation so special characters like @,&,-,+,% are not allowed' to the login field.
* My question therefore is does Wordpress require further development to stop SQL injections etc on login forms? And do I need to apply input sanitation to the login fields?
* It seems odd to not allow special characters when special characters are better for passwords so should I do this? Bare in mind that the site doesn't have public registration. It has a login feature for partners which the admin would create the login for.
Thanks
Ian | wp-login.php should not require additional effort from you to secure. However, I don't think that's what you client is asking for.

To wp-login.php, no, you don't. Not for security reasons, anyway, but that's not what your client asked for. They just asked to make "@,&,-,+,% are not allowed", which sounds like a business logic decision, and not related to security.

Converting a Wordpress widget to a block
Is it possible to convert an existing Wordpress widget to a block, without having to write a custom block (javascript)? | The short answer here is no.
Widgets are written in PHP and blocks are written in JavaScript. Beyond that there pretty fundamental differences between the two paradigms in the sense of where they are stored, markup output approaches etc.
You could take the approach of a dynamic block where the block is rendered on the front end with PHP, but you'd still need to register a custom block in JavaScript ( as well as enqueue the files ) to be able to insert it into the Block Editor.

Looking through older tutorials or code for blocks built in 2018/2019 vs the more current blocks, I see two different ways attribute values are set.
For example, the "old" way for an attribute called "content" might be:
`onChange={ (newContent) => setAttributes({ content: newContent })} `
Whereas in a more modern block:
`onChange={ ( content ) => setAttributes( { content } )} `
I get it's a minor change but I'm curious if anyone here knows why.
Thanks! | Because `{ content }` is shorthand for `{ content: content }` it's a JS thing not a WordPress thing.
Both methods work and do the same thing, but the `{ content }` syntax is shorter, so the variable was named `content` in newer examples to allow it.
Otherwise, there are no security or performance improvements, it's just a shorter syntax for the same thing. | stackexchange-wordpress | {

get_the_post_thumbnail_url does not return anything if image size is set
I want to display the post-thumbnail image in the header using `get_the_post_thumbnail_url()` with defined size, however if I am using it without specifying the size, like `get_the_post_thumbnail_url()` it is displaying the thumbnail img, but if I am using it like: `get_the_post_thumbnail_url('thumbnail')` nothing is shown.
my code in the header.php is:
<?php
function vkb_header_style() {
if (has_post_thumbnail() and is_singular()) {
$vkb_thumbnail_url = get_the_post_thumbnail_url('thumbnail');
echo 'background-image: url(' . $vkb_thumbnail_url . ');';
} else {
storefront_header_styles();
}
}
?>
<header id="masthead" class="site-header vkb-header" role="banner" style=" <?php vkb_header_style(); ?>"> | The first parameter for `get_the_post_thumbnail_url()` is the post ID or post object, and not the image size which is actually the second parameter.
So:
// Instead of this:
get_the_post_thumbnail_url( 'thumbnail' )
// You should use:
get_the_post_thumbnail_url( get_the_ID(), 'thumbnail' ) // pass a post ID
get_the_post_thumbnail_url( get_post(), 'thumbnail' ) // or post object
// Or you can pass a null to use the current post:

Which WordPress option stores the current active theme?
I always thought that the current theme is saved under the "template" option.
But looking inside the "secret" `/wp-admin/options.php` area, I see other related options.
In total, there are three:
* template
* stylesheet
* current_theme
In my WP installation all those three have the exact same value. I would like to know what each of those options really does and which one is storing the actual current theme name that WP uses when loading templates.
It may seem useless as a question but the point is that I am "studying" the WP architecture, and this is one of the current confusion points of the road. | All those options are actually pointing to the active theme, but the difference is the value stored in each option:
* The options `template` and `stylesheet` both store the name of the active theme folder, e.g. `twentytwentyone` for the `Twenty Twenty-One` theme. But if you're using a child theme, then `stylesheet` would be the name of the child theme folder, e.g. `twentytwentyone-child`.
* `current_theme` on the other hand (is or seems like a deprecated option which) stores the name of the active theme on the site, e.g. `Twenty Twenty-One`.
And this option is used by `get_current_theme()` (a deprecated function) and a deprecated option named `mods_<theme name>` (see `get_theme_mods()`).
And note that I don't have this option on my site (default install of WordPress 5.7), but if I had it, then the value would be the same as what `wp_get_theme()->get( 'Name' )` returns. | stackexchange-wordpress | {

Using 2 HTML blocks in Gutenberg to wrap content with div

How to set a Post's default visibility to 'Private' in Gutenberg?
I am trying to set a Post's default visibility to 'Private' when a user first creates the post. They should then have the ability to manually select 'published' from the sidebar dropdown once they are ready or the post has been reviewed.
My goal is to ensure posts aren't accidentally published if the user isn't ready or forgot to select 'private'.

A server-side hook failed when committing plugin code to SVN
We're trying to commit and push our initial release to the SVN repository assigned to us by the wordpress team.
However when committing the code we're getting an error (probably because of the PHP8 polyfill) but are a bit baffled why this is stopping the plugin from being deployed?
In the readme.txt and composer we specifically also set the min. version of PHP to 7.0
![enter image description here]( | After discussing this with the WP plugin review team.
The precommit hook that is being run on the server does not yet support PHP8. Removing any dependencies on the PHP80 polyfill code in vendor packages should fix this until they upgrade the precommit hooks to support PHP8.
> Just noting on the discussion above related to symfony/polyfill-mbstring the Symfony polyfills now include files which are only PHP8-syntax, but those files are only included on PHP8, the PHP7 variant is included for the rest of the users. Same situation as when the libraries added PHP 7.3/7.4 syntax and we were strictly requiring 7.0 or something.
> Using the older version of the library is the proper solution for now. The SVN server will lint with PHP8 once it’s deployed for usage on WordPress.org web requests, which while it has no timeline, I expect it’s probably going to happen at some point in the next few months, but before it’s widespread adoption. | stackexchange-wordpress | {

Including code from other themes in child themes
I'm about to build a new site based on a theme close to what I'm looking for. I understand the concepts around child theming & have read the caveats about overriding php or css files like the one described here.
Using such workarounds and calls from functions.php, is it possible to build a "Frankenchild theme" by taking chunks of a second (would-be parent) theme and patching them into the child theme? I'm not quite asking about creating a child of two parents; the child would only have one "official" parent.
As an example: Start with a Gantry basic theme and add custom taxonomy search capabilities & search results formatting (say a card-based carousel). Is that stepping over the line into plugin development? | The canonical answer is that themes are for visuals only, the rest go in plugins.
In practice though, people bundle everything in a theme because it's easier to sell a zip you upload to the themes folder. In the future it will be possible to have themes that contain little to no PHP at all thanks to full site editing.
With that in mind, if you want to take functionality from an unrelated theme, nothing prevents you copying the files over, however, this doesn't mean that it will work. You'll almost certainly need to make adjustments so that styling looks right. You may need to implement PHP and JS changes to restore the functionality.
If you can move it to a plugin then that should always be the preferred choice.
If at any point you are tempted to load the code directly from the other themes folder via `include` or `require`, do not do this. _It is extreme bad practice_ , and a very bad thing to do. There is no situation where this is a good idea. Avoid at all costs. | stackexchange-wordpress | {

How does the Gutenberg mobile/tablet/desktop preview work with media queries?
I am building a block which has different layouts for mobile and desktop. As far as I understand CSS media queries, they work when the viewport is resized.
![enter image description here](
The preview feature in Gutenberg doesn't actually resize the viewport, it just reduces the width of the container containing the blocks.
I saw that the core Gutenberg block "Gallery" changes its layout when switched between desktop and mobile preview modes. I was wondering how that works? I checked the source code and even checked the Dev tools to detect any addition/removal of CSS classes but couldn't find any.
Can someone shed some light please? | I investigated the states set using React Dev Tools and found the preview modes are set under the `deviceType` key. Went through the Gutenberg source and came across the `__experimentalGetPreviewDeviceType` function.
/**
* Returns the current deviceType.

const { deviceType } = useSelect( select => {
const { __experimentalGetPreviewDeviceType } = select( 'core/edit-post' );
return {
deviceType: __experimentalGetPreviewDeviceType(),
}
}, [] );

Formatting messed up when piping wp commands

<?php echo "hellow world"; ?>
**style.css**
/*
Theme Name: mytheme
*/
body {background: red;}
**functions.php**
<?php
wp_enqueue_style( 'style', get_stylesheet_uri() );

the solution marked is only half the answer.

wp_header();
echo "hellow world";

Add description to custom plugin setting

How to get a list of all possible values of a specific user meta key?
I have set up my posts with bookmarks where the user's meta will be updated with the post ID of the post they are bookmarking. They are stored in user meta key `my-bookmarks` as an array.
Now I am trying to query (using PHP) all of the users that have bookmarked a specific post, and list the counts by state. So 20 people from Wisconsin, 10 people from Florida, etc.
I am wondering if there is an easy way to fetch all of the possible values of the user meta key `state` from the users that have bookmarked that post, so I don't have to iterate all 50 states every single time. I would rather see that only users from 3 states have downloaded them, so let's just query the users from those 3 states.
Unless you have a better idea. | Perhaps you could create a private utility taxonomy `bookmarks`, where each term would correspond to a user. When ever a user is created a new term would be added to the utility taxonomy. As the user bookmarks or removes one's bookmark from a post, your code would attach or detach the user equivalent term from the post.
The user ID could be saved as the term name and/or slug, which you could use to do "reverse lookups" e.g. turn the term name into a integer and query single user with it.
To find out who has bookmarked a post, you'd simply use `get_the_terms($post_id, 'bookmarks')`, turn the term names to an array of IDs, and query the users with `WP_User_Query(array('include' => $user_ids))`. | stackexchange-wordpress | {

How to add ajax url to js using wp_add_inline_script()?

'map-scripts',
'const ajax_info = ' . json_encode(array(

but, it's good practice to use nonce as well for better security:
wp_add_inline_script(
'map-scripts',
'const ajax_info = ' . json_encode(array(
'ajaxurl' => admin_url('admin-ajax.php'),
'nonce' => wp_create_nonce('your_nonce_handler'), //the more specific the better

Wordpress Side Menu Admin Panel Default Order numbers List?

Why does the $_GET parameter ?search forward the front-page to the archive/blog page
I need the $_GET parameter `?search` for my front-page for a third party plugin. Whenever I enter < I get redirected to the blog/archive page. If I enter < I get redirected to `/some-page`. It appears to be a redirection only for the front-page.
Am I missing something from the docs?
Steps to reproduce:
1. Go to a WP website and add `?search` to your front-page URL
2. Go to a WP website and add `?search` to a random sub-page URL | `search` is a reserved term, and should not be used as a query variable. The presence of any reserved query variable tells WordPress that the current query must be for something other than the front page, so it interprets it as an an archive query of some sort.
The reason you get redirected to the canonical URL on other pages is because being on another page means that there are some other query variables being set that tell WordPress which page to load. These aren't present on the homepage, hence the fallback to just the blog.
The parameter doesn't actually do anything though, and hasn't for at least 15 years, but it's still reserved for possible future use. | stackexchange-wordpress | {

Remove Site Logo from Homepage in Twenty Twentyone
I am looking for a way not to show the site logo in my homepage (but on all other pages). I can manage to do this only in the nasty way, using css and display none - however, I would like to avoid that the logo is not loaded on the homepage? functions.php?
best, Aprilia | I had a quick look at the site-branding template part which handles the rendering of the custom logo on the site header. There's a conditional check on two lines against `has_custom_logo()`, along show title theme mod, which determines, if the custom logo should be rendered or not.
Internally `has_custom_logo()` calls `get_theme_mod( 'custom_logo' )` to figure out, if a custom logo has been set. This means, you can use the theme_mod_{$name} filter to change 1) the value of the theme mod and 2) the result of `has_custom_logo()`.
As code the above would be something like this,
function prefix_disable_logo_on_front_page( $value ) {
return is_front_page() ? false : $value;
}

Automatically replace   with space
In my WooCommerce online store, I frequently copy and paste product description from the OEM webpage. This works well for the most part, however depending on the site, the spaces are sometimes encoded as  . While this renders just fine in the browser, it does cause issues with text wrapping as the browser appears to see the string as one long word (so the text will inevitably overflow, unless I use word-break which will just break words in the middle).

**No.** You should never make direct requests to php files inside a theme or plugin, and you don't need to create page templates to handle AJAX requests.
If you need to handle a form, make the request to the same page that served the form and inspect the POST/GET variables.
_If you need to make an AJAX request using javascript_ , do it to the REST API. You can register an endpoint URL with a pretty url that will respond with JSON that can be easily processed in javascript.
When registering the endpoint, you tell it the name you want for the URL, e.g. `/wp-json/hossein/v1/searchdatabase`, and you tell it a function to call when it's used. That function is where you do the searching of your database, and you return the data you want to send to the browser. | stackexchange-wordpress | {

Does WordPress require port 25 for email?
My host is about to block port 25 and I'm unsure if WordPress requires port 25 to send emails like password reset, user registration, notifications etc... | WordPress sends emails via the `wp_mail()` method, which, by default, needs port 25 to be enabled in your `php.ini` settings:
> For this function to work, the settings `SMTP` and `smtp_port` (default: 25) need to be set in your php.ini file.
You will have to change this setting if you would want to send mails via another port. | stackexchange-wordpress | {

Get user meta for only the keys with a certain prefix
There is a list of meta keys with the prefix my_theme, these are updated by the user. My problem is how to get_user_meta for only the keys with my_theme prefix. Tried a wildcard, didn't work.
get_user_meta( $user_id, 'my_theme%', true ); | There is no native WordPress function to achieve this but you can get all meta keys for a given user ID and then filter the ones you need.
Here is how to do that for a given `$user_id`. First you get all the user meta entries:
$all_meta = get_user_meta($user_id);
As you can see in the get_user_meta() docs, since we are leaving the `$key` argument blank, this will contain an array with all the meta entries for the given user, including the ones you are looking for.
Then you may filter the resulting array with the PHP array_filter() function.
$only_my_theme_meta = array_filter($all_meta, function($key){
return strpos($key, 'my_theme') === 0;
}, ARRAY_FILTER_USE_KEY);
Also note that each element is again an array, in some cases you may want to dereference the resulting array in order to take only the first index of each result:
$dereferenced_array = array_map(function( $a ){
return $a[0];
}, $only_my_theme_meta); | stackexchange-wordpress | {

Ok so following your answer with the image the css target would be `.page-content`, but that could target other elements with the same class.

Increment integer field in database when WHERE needs to be dynamic

how to get users with usermeta include array of an array

Match tag names with form titles
I am trying to match tag names with form titles to fetch the correct form into the current post, to subscribe to new posts tagged with the current posts tag. I only have 1 tag assigned per post.
The code for categories works well, and I tried to transcribe it for tags, but I am afraid there are syntax errors in the code, because it does not work.
How do I write the correct code?
add_shortcode( 'subscribe-to-tag', function() {
global $wpdb, $post;
$the_tag = get_the_tags( $post->ID );
$tag_name = $the_tag[0]->tag_name;
$id = $wpdb->get_var($wpdb->prepare("SELECT ID FROM wptq_forms WHERE name = '{$tag_name}';"));
if (is_null($id)) { return ''; }
return do_shortcode( '[newsletter_form id="' . intval( $id ) . '"]' );
} ); | I don't see PHP syntax errors (like unwanted brackets) in your code, but there are two WordPress-specific issues that need to be fixed:
1. Note that `wpdb::prepare()` needs one or more placeholders (e.g. `%s` for strings and `%d` for numbers) and the replacement value for each placeholder.
So in your case, the correct `$wpdb->prepare()` would be:
$wpdb->prepare( "SELECT ID FROM wptq_forms WHERE name = %s", $tag_name );
2. `get_the_tags()` returns an array of term objects on successful requests, and each object is a `WP_Term` instance which does _not_ have a `tag_name` property, only `name`.
Therefore `$the_tag[0]->tag_name` should instead be `$the_tag[0]->name`. | stackexchange-wordpress | {

$wpdb->prepare was called incorrectly when inserting multiple records
This works:
$values = array();
foreach ( $_POST as $key => $value ) {
$values[] = $wpdb->prepare( "(%d,%s,%s)", $post_id, $key, $value );
}
$query = "INSERT INTO {$table} (post_id, meta_key, meta_value) VALUES ";
$query .= implode( ",\n", $values );
$wpdb->query( $wpdb->prepare( "$query", $values ) );
But it throws this notice:
> PHP Notice: wpdb::prepare was called **incorrectly**. The query does not contain the correct number of placeholders (0) for the number of arguments passed (3).
How can I avoid the Notice? | Well, you don't need the second `$wpdb->prepare()` and just do `$wpdb->query( $query );`. The reason is because the `$query` does not contain any placeholders just as stated in the notice; only the items in `$values` contain the placeholders, but you already prepared them in the `foreach`. Additionally, be sure to run the `query()` only if the array `$values` is not empty. | stackexchange-wordpress | {

Show latest posts in a plain HTML website custom widget
I have a plain HTML website with WP in a subfolder (/blog). I need to display latest posts from /blog into the plain HTML webpage.
Is there a PHP script or some kind of widget to achieve this?
Thanks! | Perhaps you could consider using WP REST API to get the posts with a XMLHttpRequest in javascript instead of trying to get php work on .html file(s).

> The WordPress REST API provides an interface for applications to interact with your WordPress site by sending and receiving data as JSON (JavaScript Object Notation) objects.
And

Change the Sender(not From) on wp_mail() function
I'm using the Post SMTP Plugin, but I manually send email via the `wp_mail()` function. The gmail client shows the correct From:, but when I switch to outlook or another email client, shows the different Sender: (the one that has been set up in the Post SMTP From: setting)
I have tried these filters, but only the `wp_mail_from_name` works:
add_filter( 'wp_mail_from', create_function('', 'return sanitize_email("[email protected]"); ') );
add_filter( 'wp_mail_from_name', create_function('', 'return "Test Testov"; ') );

and in another email client this:
`From: Correct Name`
`Sender: [email protected]` <\---- This is wrong. | First Disable PostSMTP plugin and delete if not used anymore it should cleanup.
Then in functions.php add the following lines
// Function to change email address
function sender_email( $original_email_address ) {
return '[email protected]';

// Function to change sender name
function sender_name( $original_email_from ) {
return 'Tim Smith';

Changing search slug from + to - (hyphen)
I've been fiddling with this all day, where I'm trying to change my search function from website.com/s?this%20is%20an%20example to website.com/tag/this-is-an-example to no avail.
