WordPress API - Get Drafts
I want to check if a post already exists. This includes to check if the post exists as draft as well. But I struggle a little bit with the wordpress API v2. <
Under **List Posts** -> status they say
> Limit result set to posts assigned a specific status.
> Default: publish
I tried to assign the value as parameter, but I get an error response:
> {"code":"rest_invalid_param","message":"Invalid parameter: status","data":{"status":400,"params":{"status":"Status is forbidden"}}}
I als asign the title of the post to check:
> filter[s] = post Title
So how to get the posts with draft state? I'm currently using the Basic Auth for developing?
I also tried
> filter[post_status]=draft
but with no success.
I have the following plugins installed: WP REST API
WP REST API - filter fields

Child Themes and Updating Parent Theme
I have not got a child theme set up for the theme I'm using, though there is an update for the theme now. I've had a google and they say that if you don't have a child theme you will loose your "customisation".
When they say customisation are they referring to any code you've altered? As I haven't altered any. Or are they referring to any content, posts, pictures, changes to the home page you've made (through the customise UI in the appearance section).
If it does refer to the content, posts etc. is there any easy plugin or other way of easily restoring that to the updated theme, without having to go through setting up a child theme? | They are referring to the source PHP, JavaScript, and CSS and really any other files contained within the parent theme's directory. If you have not modified the files within the parent theme, you shouldn't have much to worry about. Your posts, pages, and other content should not be deleted from updating a theme.
It is possible that the updated theme will handle features in different or unexpected ways. You should still back up your site's database and files prior to doing an update as a precaution. | stackexchange-wordpress | {

Method to make definitively static an abandoned WP blog
I have a blog, created with WordPress 3.4, which I abandoned some years ago but it is still receiving a good number of visits each day through Google search results.
It means a load for my mySQL server and wondered if there was a method to make the blog definitively static. I don't plan to insert new posts, and I don't allow comments on the old ones.
Any tip is welcome. Thank you very much. | Install a page caching plugin and configure it for a very very long time. This have the advantage of you being able to post things when you decide that its time to do that again.

Inserting Post Using wp_insert_post. How to Fill Yoast Plugin SEO Fields
I am inserting posts into a database using `wp_insert_post` function once the post is inserted using below line of PHP
`$postId = wp_insert_post($array)`
I can insert values in my advanced custom fields using `add_post_meta` function but I didn't find anything to insert the SEO title or the meta description specifically in the Yoast SEO plugin.
Can anyone help me with this? | You can use the update_post_meta function to insert the Yoast Plugin data. Yoast uses 3 post meta keys for each post:
1. _yoast_wpseo_title ( use for SEO title )
2. _yoast_wpseo_focuskw (For meta keywords )
3. _yoast_wpseo_metadesc (For meta descriptio )
You can find all these meta key under postmeta table
$new_id = wp_update_post($array);
update_post_meta( $new_id, '_yoast_wpseo_title', 'SEO Title' );
update_post_meta( $new_id, '_yoast_wpseo_focuskw', 'keyword1 keyword2' );
update_post_meta( $new_id, '_yoast_wpseo_metadesc', 'SEO Meta Descr' );

How to automatically add edit link on frontpage post of any wordpress theme?
Hi I searched google for a plugin to do so, I can't find any. Can you recommend me one if not can I create it myself though I'm beginner in wordpress dev ? If yes can you give me some clues.
Thanks.
Update: I'm not interested in having edit link in admin bar; I bought a plugin which instructs me something I don't want to do by hand on dozens of themes :
 | As lot of themes use `the_content()` to display the post content. you can use `the_content` filter hook to add the edit link before/after the content.

Internationalize Forum Posts Without Translating Them
I would like to internationalize my forum. I would like for users to be able to display the forum in 2 languages.
The language will be determined by the url.
I downloaded a plugin called Polylang to help me with this.
This works well until it comes to displaying posts (ie: questions). I'm interested in displaying the posts in their original language regardless of the user's current locale (ie: page elements such as header and footer will reflect the user's locale while the post will be in its original language).
I would like a given post to have urls like: www.example.com/blog/fr/some-post www.example.com/blog/ru/some-post
Is this possible? The only possibility to do this with Polylang would be to enter the exact same post for each language. But it seems inefficient and incorrect to do this.
Does anyone have any suggestions for how I might achieve this?
Thanks. | The plugin WPGlobus allowed me to achieve what I stated in the question. | stackexchange-wordpress | {

Add class or ID to any Wordpress function
I often find the need to add class or ID's to Wordpress functions. Preferably I would like to do this in the a template (not in `functions.php`).
Example: `<?php the_excerpt(); ?>` Will output the excerpt inside `<p>`. How can I add a class to the paragraph so that I get `<p class="something">The excerpt text...</p>` | If you have only one template it's fine to do something like:
echo '<p class="whatever">' . get_the_excerpt() . '</p>';
However, if you have multiple templates and want to control the classes centrally, you can make a filter on `get_the_excerpt` as follows (but yeah, that would be in `functions.php`):
add_filter ('get_the_excerpt','wpse240352_filter_excerpt');
function wpse240352_filter_excerpt ($post_excerpt) {
$post_excerpt = '<p class="whatever">' . $post_excerpt . '</p>';
return $post_excerpt;
}

Preserve Javascript Through Customizer Preview Navigation
In the Customizer you can add some javascript and put your control transport to `refresh` so that whenever the user changes a setting it automatically gets reflected onto the website preview panel:
// Body Background Color
wp.customize( 'body_bgr_color', function( control ) {
control.bind( function( value ) {
$( 'body' ).css( 'background-color', hex2rgba( value, 1 ) );
} );
} );
I'm enqueueing my script using the `customize_preview_init` hook.
The issue happens whenever the user users the main navigation to go to the next page - the javascript changes are lost but preserved on the Controls Pane. How can I preserve or rerun the javascript whenever the user navigates to a new preview page? | Since I'm saving everything on hard save ( button click ) I was trying to avoid updating all the options via ajax. What the below does is as the preview pane is setting up the JS binding, I trigger a "change" which will reapply the controls value to the element.

jQuery( document ).ready( function( $ ) {
// Body Background Color

$( 'body' ).css( 'background-color', hex2rgba( value ) );

Is there a predefined callback function for custom categories?

'myCustomPostType',
'side',
'high'
);
When using `add_meta_box`, is there a predefined callback function for custom categories, such as `post_categories_meta_box`? | The callback you're looking for is `post_categories_meta_box` which we can use via a custom callback.
// Add your custom meta box.
function your_custom_meta_box() {
add_meta_box( 'your-custom-meta-box', 'Custom Meta Box', 'my_taxonomy_meta_box_cb', 'post', 'side', 'high', null );
}
add_action( 'add_meta_boxes', 'your_custom_meta_box' );
// Our custom callback.
function my_taxonomy_meta_box_cb( $post, $box ) {
// Pass in the taxonomy we'd like to use.

how to force tag page layout to use same as search layout?
I have remarked that when clicking on a tag I have a list of posts displayed differently that when I use search box.
How to force tag page layout to use same as search layout for any template ? | You can tell WordPress to use the `search.php` template whenever viewing tags by using the `template_include`. It works like this:
function wpse_240429() {
// IF we're planning on loading a tag template

// Try to locate the search.php template
$search_template = locate_template( 'search.php' );

// Use search.php for display purposes
return $search_template ;
}
}
}

Automate specific steps on WordPress install

Media files exist in upload folder but not showing up

Why is it happening? | Just by uploading files into the `wp-content/uploads` won't show up in the _Media Library_ , those media ID's needs to be there in the database to show up in the Media Library.

Retrieve tags data in post body

style="background-color: <!--Tag Color--> ">
<!--Tag Name--> </a>
I use default WP Taxonomy for tags, and I created a custom field "tag-color" for Tags using ACF. Does anyone have an idea of what is the best way to do that? | There are two ways to approach this: modify the existing `the_tags` function or build your own.
`the_tags` ultimately relies on `get_the_term_list`, which returns a list of hyperlinked tags. You would have to use regular expressions to add classes and styles to that using a filter. That would be quite cumbersome.
So, my preferred approach would be to construct a function yourself. Start with an array of tags and loop through them:
$all_tags = wp_get_post_tags (get_the_ID(), array('orderby' => 'name', 'order' => 'ASC', 'fields' => 'all'));
$output = "";
foreach ($all_tags as $tag) {
$tag_style = // get that from ACF
$tag_link = get_tag_link($tag->term_id);
$tag_name = $tag->name;
$output .= '<a class="tag-button w-button" href="' . $tag_link . '" style="' . $tag_style . '">' . $tag_name . '</a>';

> Creates or updates a modification setting for the current theme
and `get_theme_mod()`:
> Retrieves a modification setting for the current theme
With this you should be able to get the logo:
$custom_logo_id = get_theme_mod( 'custom_logo' );
$logo = wp_get_attachment_image( $custom_logo_id, 'full' );

get_terms sort order with child categories of varying depth

Network activating; if ( !current_user_can( ‘manage_options’ ) ) locks me out…
iHi,
I use this snippet in a plugin;
if ( ! ( current_user_can( 'manage_options' ) ) )
do something
}
but problem is, when network activating this on a multi-site installation, I get locked out of admin pages. WP says “You don’t have authority to this page” or something (translating from Swedish).
I have, by trial and error, limited down the problem to the function "current_user_can" but is_super_admin gives the same result. I get locked out. Please note that this only happens when network activating on a multisite installation. If I activate the plugin per site everything works as expected. See github for an example of how I try to implement it.
How come? I’ve tried it out many times and tried to tweak the code, but I can't get it to work.
Any better way of checking it user does NOT have authority to manage options (does not have admin capabilities)? | Thanks for your advice. In fact it is a hook that I fire of with this check.

and the function is;
function ngo_remove_eo() {
remove_menu_page( 'edit.php?post_type=event' );
}

add_action( 'wp_loaded', 'eongo_cleanup' );

if (!(current_user_can('manage_options'))) {

Modifying the Search Results
I want to inject additional search results along with the search results provided by WordPress for the site search feature. Basically, I need to find the WP_Query object that the search uses, and modify it.
I figure I should use the `posts_pre_query` filter, and return an array of post objects - some of which will be real post objects, and others which will be "fake" posts objects that represents results from the other sources.
The problem I have is, how do I detect that this is a public search query - what characterizes a WP_Query instance that is a public search result? | add_filter( 'pre_get_posts', '__filter_pre_get_posts' );
function __filter_pre_get_posts( $query ) {
// this is to detect a public search query

Where am I gaining 6px height retrieving buddypress avatar
I'm currently in the process of building a social network based site using buddypress and when the user is logged in I want to display their avatar in my header. To do this I've used this code.

<a href="<?php echo bp_loggedin_user_domain(); ?>">

Intercept the "lost password" action by first redirecting to an existing instructions page
We have a situation where the users (children) keep not forgetting their password but making trivial mistakes while trying to login.
As per question they should be first redirected to page e.g. id=5 with instructions like:
> Please go back and:
> Activate your cookies
> Check if the correct language is on your keyboard
> Ask your mother to log you in
> etc...
> If none of the above works please click here (< to ask for a new password
So, the lostpassword link on the login page should redirect to the existing page with the custom message/instructions **and then** , the link on the page to the actual lostpassword link.
_PS: I believe that the lately introducedlostpassword_post hook could be useful._ | This is straightforward.
1. Hook on init to detect the lostpassword page
2. If the user is not coming from your instructions page (which we defined by adding extra query parameter) he'll be redirected to your custom page
3. In your custom page add the link to lost password page including the extra parameter we set to skip the redirection.
add_action( 'init', 'lostpassword_instructions' );
function lostpassword_instructions() {
global $pagenow;
if ( $pagenow == 'wp-login.php' &&
isset( $_REQUEST[ 'action' ] ) &&
$_REQUEST[ 'action' ] == 'lostpassword' &&
! isset( $_REQUEST[ 'skip' ] )

Is it possible to set custom post type revision limit inside the theme files?
i want to be able to set the revisions limit number of a specific post type. i know there is a plugin for that, and i know it can be set through the "wp-config.php" file, but **my question is:**
Is there a simple short code i can implement on my theme to do that without a plugin and without the need to change other files out of the theme folder scope? | I had a look at the `wp_revisions_to_keep()` function. There's a filter called `wp_revisions_to_keep` that overrides the value of `WP_POST_REVISIONS`.
Here's an untested example ( _PHP 5.4+_ ):
add_filter( 'wp_revisions_to_keep', function( $num, $post )
{
// Post Types and Revision Numbers - Edit to your needs
$config = [
'post' => 10,
'page' => 9,

// Override the WP_POST_REVISIONS value

$num = $config[$post_type];

To have Wordpress interact with memcached it must be installed as a PHP extension?
I have the `Memcached` Daemon running on my server but some plugins for wordpress don't see it (i.e. W3 total Cache).
Do I need to configure it as a PHP extension to use it?
I've found this answer: W3 Total Cache doesn't detect memcached and this article <
but some explanation would be very useful | This depends on what is it that you are trying to do/use. In theory the protocol used to communicate with memcached server is not very complex and can be implemented in PHP, and therefor as a plugin. In practice you might want to prevent collisions of multiple processes writing at the same time to the cahce which will most likely require the access to the multi tasking API of the OS, something that is not built-in in the default PHP modules and will require you to use additional modules in any case. (there is also probably some performance argument that can be made here between running C and PHP code, but I am not sure how important it is).
Having it as module also let you as the server admin "break out" of whatever restrictions you put on the PHP code in the php.ini and other setting files (in theory you can block the ability of the PHP application to connect anywhere, although I never heard of anyone doing that) | stackexchange-wordpress | {

Can not using get_header() cause trouble (later on)?
Can not using `get_header()` cause trouble (later on)?
I can think of several reasons of not using `get_header()`, for example if you would be making a one page website or you want to use some other php templating system or you want your header.php to be in a subfolder.
I know get_header() is basically the same as get_template_part() except for the fact that it does a `do_action('get_header')` (and uses require_once).
So the real question would be can not having `do_action('get_header')` inside of your template cause trouble? | As long as the `wp_head()` function is still being called in the template, you should be fine.
You've pretty much summed it up in your question; by not using `get_header()`, the `get_header` action will not be fired, but that wouldn't matter for your particular use case.
Using `get_header()` along with the name parameter would be the more "WordPress way" of doing it though:
`get_header( 'single-page-app' );`
Would use the file `header-single-page-app.php`. `get_header()` uses `locate_template()` internally, which does not search sub directories, so this approach would not be suitable for your use case. | stackexchange-wordpress | {

How to Add an Index to Plugin Database table
I've created some additional tables for a plugin I'm developing and need to add indexes to these tables.
What's the WordPress way to do this?
Using `dbDelta()` doesn't seem to be working, and I'm not seeing any error in the logs. | You can execute _arbitrary_ SQL statements with wpdb::query(), including Data Definition Statements, e.g.

**Note:** Because `$wpdb->query()` can execute _arbitrary_ SQL, if the statement you pass to it contains **ANY** user input, then you should use wpdb::prepare() to protect against SQL Injection attacks.
But this raises the question: how did you create your plugin-specific tables? "Manually" or programmatically? If programmatically, did you not use `$wpdb->query()`? If you did it "manually", then you really should create the tables (and their indexes) upon plugin activation.

How to get site URL if database is disconnected?
Recently I realized that you could include a db-error.php file in your `wp-content` directory from "How to monitor server for error establishing a database connection" that would replace the existing WordPress database error message with something custom.

header("Location:

Is there a way to get the site URL without a database connection that could be used in the header redirect? | One option is setting the site's URL in the `wp-config.php` file itself. This effectively overrides the `siteurl` option that's otherwise stored in the database, but it also means you can reference the URL without doing a query.

>
> Add these two lines to your wp-config.php, where "example.com" is the correct location of your site.
>
>
> define('WP_HOME','
> define('WP_SITEURL','
>
After that, using code in a regular theme that checks the `siteurl` or `home` option will pull from the constant rather than the database (hence my note on the override above).

Custom query var rewriting with only variable
On every post there is a "read" (default) and "listen" button that users can click on without page refresh.
The listen tab can be accessed directly through
domain.com/category/post-title/?listen=listen
and
domain.com/category/post-title/listen/listen
I would like to edit the rewrite rule so that the same page can accessed though
domain.com/category/post-title/listen
How would I go about doing this?
My code:
function cp_narrations_query_vars( $qvars ) {
$qvars[] = 'listen';
return $qvars;
} add_filter( 'query_vars', 'cp_narrations_query_vars' , 10, 1 );
function cp_add_my_endpoint(){
add_rewrite_endpoint( 'listen', EP_PERMALINK );
} add_action( 'init', 'cp_add_my_endpoint' ); | Answered thanks to Milo's comment.
I wrote a small function to check if the query variable exists. Note that `get_query_var('listen')` didn't work for me.
function is_listen() {
$vars = $GLOBALS['wp_query']->query_vars;
if ( array_key_exists('listen', $vars) ) {
return true;
} else {
return false;
}
}
Use it in a conditional like so:
if ( is_listen() ) {
// Display listen tab

Are custom post types suitable for storing high numbers of data elements, in this case chat messages?
I'm developing a system that will have around 2k users and they will be communicating with an internal live chatting system.
Now I'm wondering if it's a good choice to store messages as custom post type? Or it's better to use custom table for them? | As far as I can see, the main problem you might have to deal with is having to store a fairly large amount of chat messages.
So to avoid making WP core functionalities querying post and postmeta from large amount of rows generated by your single functionality, it seems obvious to me you'd better create a custom table.
I believe this would also offer to you the possibility to optimize your table's structure for your specific usage which would result in faster queries.
**At this time** , WP postmeta queries get very slow generally speaking, when they have to deal with a large amount of rows. Look at the problem WooCommerce actually has when dealing with over 100k products which they store as post and postmeta. They're on the way of fixing this by migrating all the products inside custom tables... | stackexchange-wordpress | {

Remove header title form page through CSS
I would like to change the size of the message on my shopping-cart page, for example:
<
If a product is added, there a large message appears ( _Winkelwagen_ ). I messed around with inspect element and got rid of the extra space, but I'm not versed in coding enough to get the right code in the `style.css` file of my child theme.
Is there any way I can simply get rid of the following for that page?
<div class='c12 end pageheading'>
When I play around with it in the inspect element the problem disappears. Does anybody have suggestions? | To hide the title ( _Winkelwagen_ ) from that page:
;
function hide_winkelwagen() {
?>
<style itype='text/css'>

$wpdb Mysql trigger problem
This is an extension of this question : SO
I want to implement the mysql trigger helpfully provided by @Shadow into a Wordpress plugin. The query=trigger is
$sql_trigger = "
drop trigger if exists bi_tbl_B $$
delimiter $$
create trigger bi_tbl_B before insert on tbl_B
for each row begin
DECLARE v_slug as varchar(255);
DECLARE v_url as text;
SELECT url, slug INTO v_url, v_slug FROM tbl_A WHERE id = NEW.id;
NEW.url=v_url;
NEW.slug=v_slug;
end;
$$
delimiter ;
";
mysqli_multi_query($wpdb->dbh,$sql_trigger);
I have few questions:
1) Is this query correct or I need to make changes?
2) Do I have to use any one of this
`global $wpdb;` or
$mysqli = new mysqli();
$mysqli->connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
3) Is the query safe? | 1. No idea
2. yes, use `$wpdb`
3. seems like it should be. OTOH if this is something you want to do in a plugin, I am not sure if normal wordpress users (as defined in the DB) have trigger creation privilege.
just be careful with what you are trying to do, as if you have object caching and the data you create is read by wordpress APIs, you might end up with a mismatch between the cache and the DB. | stackexchange-wordpress | {

List child pages within page template
I am building a page template within a theme that lists child pages for a product page.
Is it possible to change this so that it lists the children of the page the user is on rather than having to specify a page ID?
My code
<?php
$args=array(
'post_parent' => 27641, // This page!
'post_type' => 'page',
);
$my_query = null;
$my_query = new WP_Query($args);

<ul>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<li>
<a href="<?php the_permalink() ?>" title="<?php the_title_attribute(); ?>" itemprop="url">
<?php the_title_attribute(); ?>
</a>
</li>
<?php endwhile; } ?>
</ul>
<?php wp_reset_query(); // Restore global post data stomped by the_post().?> | The ID of the current page is available via the global $post variable, so to get the ID use:

Replace post's "the_content" with ACF value
I try to replace post's `the_content` with value from ACF field `article_text`. I managed to achieve it with following method:
$postid = get_queried_object_id();
$my_post = array(
'ID' => $postid,
'post_content' => get_field('article_text'),
);
wp_update_post( $my_post );
the_content();
But I have a small issue with it: when I create post, `the_content` doesn't automatically gets the value from ACF `article_text`. I have to refresh the browser couple times in order to see that change. When I preview the post without publishing, I cannot see `the_content` at all.
My question - is there a more efficient way to do it to see the content straight away?
The reason why I want to display `the_content` instead of `article_text` is because of several not-ACF-friendly plugins. | Instead of updating the post's content, you can filter it using the `the_content` filter.
add_filter( 'the_content', 'wpse241388_use_acf_field' );
function wpse241388_use_acf_field( $content ) {
return get_field( 'article_text' );
}

add_filter( 'the_content', 'wpse241388_use_acf_field' );
function wpse241388_use_acf_field( $content ) {
if ( is_singular( 'article' ) ) {

Can we have private drafts?
As per the documentation, Draft and Private are two mutually exclusive post statuses. Therefore, when you mark a draft post as Private, it is no longer a draft.
We are a big team making extensive use of private posts. Therefore, we would like to mark a draft as private (an unfinished post that will be internal). Ideally, the "publish" button would un-draft the post, not make it public.
To put it differently, we need both a (draft / finished post) distinction, and a (public / private post) distinction.
Is that possible? Do we need a custom post status? | I would probably create a custom field / check box for this for a draft stage. Then hook into post status transition (or around) and when post is published force it to only private, even if normal publish was pressed.
From personal experience custom post statuses are a wreck. They _seem_ like a good idea, but they just introduce mountain more of access and visibility problems since core code never cared much for any non–default status. | stackexchange-wordpress | {

wp-cli regenerate media is not working for custom sizes
I'm using `wp media regenerate` to generate thumbnails. While this works for the built-in Wordpress image sizes (even when the width and height are customized in `functions.php`), it does not work at all for custom image sizes. The command finishes and the custom sizes simply are not generated. The original images are much larger than the sizes being generated, so it's not related to upsampling. I've also tried declaring the custom sizes using the `after_setup_theme` action hook, but the result was the same. Does `wp media regenerate` only work for the built-in media sizes, or am I doing something wrong?
**functions.php**
// Built-in sizes work
update_option("large_size_w", 2000);
update_option("large_size_h", 9999);
update_option("large_crop", 0);
// Custom sizes don't work
add_image_size("Custom Size", 320, 320, true); | I finally figured this out. It ended up being something really stupid. I have short tags enabled on my server so I can use `<?` instead of `<?php` in theme files. I was also using a short tag to open my `functions.php` file. Apparently, when PHP scripts run from the command line, they require the full `<?php` open tag, otherwise they just echo to the console. I made this change in my `functions.php` file and it works now.

WpAlchemy - _global_head is being output 3 times
Today while attempting to make use of the repeating fields function (have_fields_and_multi) I've discovered that with the latest WpAlchemy (1.6.1) and the latest Wordpress (4.6.1), the inline JavaScript blocks from MetaBox.php are output 3 times on the admin page.

Do my defines need to be unique?
In the root file of my plugin (`the-plugin/the-plugin.php`), I've set up some defines that I will be using throughout my plugin:
# Plugin's latest version
define( 'THEPLUIGN_VERSION', '2.0.0' );
# Minimum WordPress version required
define( 'THEPLUIGN_MIN_WP', '3.7' );
# Minimum PHP version required
define( 'THEPLUIGN_MIN_PHP', '5.3' );
# Plugin base
define( 'THEPLUIGN_BASE', plugin_basename( __FILE__ ) );
As you can see, I've prefix the defines with `THEPLUGIN_`, I assume this is necessary to add in order to keep each of the values unique and to prevent conflict with other plugins. Is this true? Or is there a better way to define these values, globally, to be used throughout my plugin?
I've implemented both namespaces and class structure in my plugin. | Yes they do, the more interesting question is why do you use define instead of `const`? Take a look here: define() vs const.
The only situation in which you should use a define over `const` is if you want the user to be able to override your defines in `wp-config.php`. Obviously things like minimum php version should not be overridable.
Once you go with const you can just use namespaces and get over the whole issue. The only problem is that const before PHP 5.6 could not be assigned an expression and you have two defines which are not simple values.
If you target PHP 5.6 and above then, in my opinion, just use `const`. Otherwise defines should be avoided as they can be overwritten by mistake, but it is your judgment call about using defined values instead of calling the relevant APIs. | stackexchange-wordpress | {

How to Backup and Transfer Everything to Another WordPress Site?
After doing much research, I give up and finally decided to ask this question here.

How to change footer or <div> for different kinds of users in wordpress?

background: black;

Functions - callback vs fallback
While seeing the source code of some themes or plugins, I have noticed that, sometimes these two words are used to denote/indicate other functions.
What's the difference between them? Which function should be called `callback` function and which is `fallback`?
Can you give me an example?
Thanks in advance. | That is not really a question in the focus of WordPress, is also in other programming languages and in our speaking language a topic. Maybe I can clear the difference between these words with a non coding example.
## Callback
A return of a situation to a state. Like a call with the telephone to a message of the phone or the answering machine to a defect of a product.
In the coding context is a callback a function/method which executed after the current effect is finished.
## Fallback
An act of falling back. Like an alternative plan to the current idea, progress.

Edit post_content on posts with Featured Image

How can I make a shortcode from this code?

function item_count() {

}
add_shortcode('count', 'item_count');
But the echo is triggering a 'headers already sent' error.
I've since learned that shortcodes should 'return' rather than 'echo', but haven't been able to figure-out what I need to do to use this as a shortcode. | It should be as simple as this:
function item_count() {
$dir = '/PATH TO DIRECTORY/';
$filecount = 0;

while ( $f = $d->read() ) {

$filecount++;
}
}
}
return '(' . $filecount . ')';
}

If that's still giving you a Headers Already Sent error, then check to make sure that there's no whitespace at the end of your PHP file. (You can safely omit the closing `?>` tag, which will help you ensure that there's not any extraneous whitespace.)

I want to be able to sort the table by clicking on the table `TH` cell containing the custom field name.
I've been pointed to meta query clauses by ACF support, but I'm out of my depth with those.
I'd really appreciate some help in generating URLs to wrap around the the custom field name in each `TH` element. | To follow up on @rock3t's comment, do you really have to query the backend whenever a user clicks on a column header?
Have you looking into using the jQuery tablesorter? It allows an end-user to sort an HTML table by doing DOM manipulations.
I've never used it in a WP project, but I have used it extensively in other projects I've built and it works great. It's **very** configurable, so I'm sure it will satisfy your needs.
tablesorter is **not** one of the jQuery plugins included with WP Core. So you'll have to download it (from the above link), include it in your plugin/theme somewhere and enqueue it. Then, enqueue a simple JS file that would like something like:
(function ($) {
$(document).ready (function () {
$('#id_of_your_table').tablesorter ({widgets: ['zebra']}) ;
}) ;
})(jQuery) ;
You can read more about how to use tablesort in their docs, including various other parms to the `tablesorter()` method. | stackexchange-wordpress | {

How to delete an user including data from custom database tables

Redirect short-form URL to long-form URL (post_id to post_id + post_name)
My blog uses this custom structure for permalinks:
> /%post_id%/%postname%/
>
> e.g.: <
Articles can then be accessed and linked to in two ways:
* Short form. e.g.: <
* Long form. e.g.: <
* The canonical URL (set with `<link rel="canonical">`) is the long-form URL.
This is handy because, this way, links are shorter. Useful for sharing on Twitter.
What I'd like to do, is **create a redirect from the short-form URL to the long-form URL.**
My question is: where to do that?
As I understand it:
* `add_rewrite_rule` is not appropriate -- I cannot access `post_name` from it.
* `add_permastruct` is not appropriate either -- I cannot declare a redirection in it.
I guess I should create a hook somewhere, but where? | I think can do:
add_action('template_redirect', 'my_func');
function my_func(){
if(is_single()){
// catch the last string

$last_phrase= $new_array[2];
if(is_numeric($last_phrase)){
$id = $last_phrase;

How to create a front end user profile with a friendly permalink and a 404 trigger
I've implemented the accepted answer from this question and works great:
How to create a front end user profile with a friendly permalink
But it does not trigger a 404 if you just enter anything /user/asdasd
I'm thinking it needs to happen at some point in this section of code:
if ( array_key_exists( 'user', $wp_query->query_vars ) ) {
include (TEMPLATEPATH . '/user-profile.php');
exit;
}
So check the query_vars then maybe run that through the users database to check?
I'm not really sure how to integrate a 404 redirect if the url is not a user.
Maybe it is something that I put on user-profile.php to check if it returns anything about the user, if not, load the 404 template? | I believe the solution here would be as simple as you've generally described it.
Assuming conveniently that `$wp_query->query_vars['user']` contains the **username** and not its **ID** :
if ( array_key_exists( 'user', $wp_query->query_vars ) ) {
if ( username_exists( $wp_query->query_vars['user'] ) ) {
include( TEMPLATEPATH . '/user-profile.php' );

Can I Hook Into the TinyMCE Insert/Edit Link Button to Use Shortlink For Post?
The idea here is to be able to use the Link button to search through posts as usual, but, once selected, use the shortlink (with something like `wp_get_shortlink();`) instead of the permalink:
`<a href=" Link</a>`
Not sure if it would be easier to add this function to the existing button or add a new button with this dedicated behavior. | If you mean the _link dialog_ , then we can modify the _permalinks_ with the `wp_link_query` filter:

{

Impossible User Registration

WP API Get post with tag names instead of tag ID's
When you request posts using WP API's search mechanism, it returns tags as one of the post's properties, but it is an array of tag IDs, not tag names. Is there a way to make the API include the name of the tags without making subsequent requests to the API by tag ID for each one?
tags: [
188,
30,
151,
189
]
I couldn't find any parameter in the API docs that does this, so I was thinking of creating a custom plugin to maybe filter and substitute the tag ID's for names before the response is sent back to the API caller. In that case, what action should I listen for? | I figured something out based on what I found at this post.
Basically I need a plugin that listens for when the REST response is about to go out. The plugin code would be similar to the following:
function ag_filter_post_json($response, $post, $context) {
$tags = wp_get_post_tags($post->ID);
$response->data['tag_names'] = [];
foreach ($tags as $tag) {
$response->data['tag_names'][] = $tag->name;
}
return $response;
}
add_filter( 'rest_prepare_post', 'ag_filter_post_json', 10, 3 );
It adds the tag names as a new property called `tag_names`. The rest of the heavy lifting is done by the `wp_get_post_tags` function. | stackexchange-wordpress | {

Should I install plugins to my WordPress installation from web sites having in URL "nulled" or, "null"?
I would like to bring some attention to WordPress people. On few places or Websites you may find some plugins for free that usually cost money. These websites usually have "null" or "nulled" in URL.
Should I install them? | No. This is a security risk. Not only morality question.
I checked some of these plugins and found most of all of these are infected. For instance, they will use `base64encode` functions and evaluate in the end to send info from your web site to URLs in Panama, Iran or like.
They may write to your `license.txt` or `readme.txt` files for instance, and in that way the hackers can get your credentials.
**Note** There may be honest businesses having "null" or "nulled" in URL so I would like to enclose, since I meant specifically those web sites delivering hacked plugins. | stackexchange-wordpress | {

Strange characters added to the database
So I am migrating over a Wordpress website it has quite a lot of custom fields, long titles and a lot of images.
When I make the migration over the database is not seen and Wordpress goes to a fresh install page, then it makes up a new database. In PhpMyAdmin I can see the old database is still there and it uses normal conventions like wp_commentmeta but the new version (the one WP has no problem seeing but no info from the old site) puts in odd characters like wp_z5v95e_commentmeta?
Even if I kill the database, rename it, re-du the con-fig file, get rid of the plugins, get rid of the theme, do a fresh WP install and I still get wp_z5v95e!
If I have to start from scratch and rebuild the site so be it but it also doesn't see the media library which is key due to the amount of images in the website.
Has anyone seen or know what this is?
Thanks | The strange characters you are referring to are part of the table prefix. This is configured with the variable `$table_prefix` in the file wp-config.php.
$table_prefix = 'wp_';
When migrating a WordPress installation and setting up a new wp-config.php file you have to make sure, the prefix stays exactly the same as in the former config file. Else all database tables have to be renamed accordingly. | stackexchange-wordpress | {

Do action only on certain front end pages?

}
else {
echo "this is the wrong page". "<br>";
}
}
}
add_action('wp_head', 'asdf');

Is there a get_post(s) filter that can alter/replace the output completely?
I would like to create a plugin that creates a JSON cache of saved/updated data. But for the plugin to be general purpose I'd need it to override the output of `get_posts` and other `get_functions`.
I know that html cache is faster and that good plugins already exist for that purpose, but this would be a nice thing to have when building a SPA, and in scenarios where table locking occurs like in Woo Commerce sites.
There are hooks like `updated_post_meta` and `post_updated` but I couldn't find the `get_posts filter`. There is `pre_get_posts` but it only allows for the `$args` modification, the underlying `WP_Query` is still ran. | If you look towards the end of the query process (which starts with the `pre_get_posts` filter), there is a filter called `the_posts` (not to be confused with `the_post`). This allows you to modify the output of `get_posts` completely, as you asked.
Beware that this only works if there is no plugin or so that suppresses filters on `get_posts`. Also note that this doesn't work on `get_post`. | stackexchange-wordpress | {
