Disable wordpress comments API
We're using the disqus plugin on our wordpress site, so anyone commenting should have a login through disqus. Yet, I'm still seeing spammers trying to post through the regular comments API. They're not getting through to the post, but they're clogging my inbox as admin.
How do I disable this API - I only want to accept comments that come from a logged in Disqus user? | There is much easier way to close standard WordPress comments. Just add
add_filter( 'comments_open', '__return_false' );
to your `functions.php` file and comments will be closed. | stackexchange-wordpress | {

Get search.php results in header.php?
I want one image in header.php to change for different pages.
The function in header.php looks like that:
if(is_archive()):
//change image to "Archives"
endif;
if(is_404()):
//change image to "404"
endif;
Now, is it possible to check if page is the search page AND what's the search string AND how many posts were found?
So what I want to do is basically:
if(is_search()):
//change image to "Search" AND echo %s
endif;
if(is_search_empty()): //yes I made this up
//change image to "Nothing found" AND echo $
endif;
Is it even possible outside the search.php page loop? | > Now, is it possible to check if page is the search page
is_search()
> AND what's the search string
is_search() AND print get_query_var( 's' )
> AND how many posts were found?
is_search() AND print $GLOBALS['wp_query']->number_posts()
… or if you got a custom query…
$my_query = new WP_Query( array( /* whatever args */ ) );
is_search() AND print $my_query->number_posts() | stackexchange-wordpress | {

Run function on settings save
I am using the Settings API for a plugin's settings page. One of the settings allows the user to change the cron job interval for the cron job created by this plugin.
Therefore I'd like to run a function on saving of the settings page, which checks the value in the database and compares it to the value the existing cron job has. If they are different, the cron job should be recreated.
Is my logic right, and if so how can I run such a function after the plugin settings have been saved? | I'm not familiar with wordpress settings api but I know those options generated by settings api are handled/saved in wp-admin/options.php
Unfortunately,
if ( isset( $_POST[ $option ] ) ) {
$value = $_POST[ $option ];
if ( ! is_array( $value ) )
$value = trim( $value );
$value = stripslashes_deep( $value );
}
update_option( $option, $value );
as you can see, no hook before update_option.
But there is a workaround:
add_settings_field('..','..','callback');
function callback(){
if($_GET['settings-updated']=='true'){
//do your cron update stuff here.
}
echo 'output <input or something';
}

How to use the 'comments_number' filter?
I'm not sure how to use this filter. Could someone show me an example? I'm trying to change `('0', '1', '%')` to `('0 Comments', '1 Comment', '% Comments')`.
I'm using this function to get the comments number.
function lpe_get_comments_number( $anchor='#comments' ) {
$return = '<a class="comments-number-link" href="' . get_permalink() . $anchor . '">';
$return .= get_comments_number(); // '0', '1', '%'
$return .= '</a>';
return $return;
}
I know I could just set the arguments here and call it a day, but I was hoping to store my custom functions away in a different file and handle their settings from the themes functions.php. | The filter you mention is used by the end of `get_comments_number_text`. As you can see from the source the number of comments is passed through the filter, allowing you to completely change the default text. Like this:
add_filter ('comments_number', 'wpse89257_comments_number', 10, 2);
function wpse89257_comments_number ($output, $number) {
if ($number == 0) $output = '0 Comments';
elseif ($number == 1) $output = '1 Comment';

How do I use a custom theme for the WP Maintenance Mode plugin?
How do I use a custom theme, rather than the themes included with this plugin?
Here is the link to the plugin: <
I see that under the plugin's settings there is a way to choose "own style" theme and a way to link to custom stylesheet, but I want to use my own html as well. | How to do this is on the front of the plugins wordpress.org page.
<
> You can add your own html and stylesheet and add the url of this style to the options of the plugin. Write your style to this markup and upload to the webspace; after add the url include http:// to the settings of this plugin and change th theme to "Own Theme":
Which while it is ambiguous, the settings page does offer an alternative. If you upload a dedicated maintenance html page, then use the redirect feature to redirect to it, you would have full control over the page.
It may be that this plugins themes are purely CSS based. You may be able to use the hooks and filters provided to remove and add items of content and markup, but redirects are the simplest method.
**edit:** After some talk with the plugin author, I've gotten the readme for the plugin and terminology changed, it seems if you put a `wp-maintenance.php` in wp-content it will use that instead of the default html. | stackexchange-wordpress | {

increase maximum upload file
I want to increase the maximum upload file (media default:32mb). Before posting i search, but i didn't have the result that i want. My host didn't support .htaccess. I create my own `php.ini` with these:

Contact Form 7 Plugin emails not being received by some accounts

They claim that none of the messages end up in their spam folders either.

changing permalink for custom template in posts of a certain category
I've created a unique single post template to give people the option of reading all posts of a certain category using the awesome "reveal.js" which they access via this link
<a href="?show=presentation/">presentation</a>

website.com/post-name/?show=presentation
website.com/completely-different-post-name/?show=presentation

website.com/post-name/presentation/
website.com/completely-different-post-name/presentation/
I've spent the last 10 or so hours trying to figure this out (I haven't even gone to sleep yet, lol); unfortunately, nothing has worked.
Is there a way to do this?
As a side note, the site I'm trying to do this on is installed in a subdirectory (localhost/wp) but I'm developing this for my actual website which is installed in a top level directory | You can achieve this via the Rewrite API's `add_rewrite_endpoint`:
function wpa89344_add_presentation_endpoint(){
add_rewrite_endpoint( 'presentation', EP_PERMALINK );
}
add_action('init', 'wpa89344_add_presentation_endpoint');
Then in your template or wherever you differentiate a presentation vs normal view, check the global `$wp_query` for the presence of the `presentation` query var:
global $wp_query;
if( isset( $wp_query->query_vars['presentation'] ) ){
include(TEMPLATEPATH . "/single_wide_report.php");
} else {
include(TEMPLATEPATH . "/single_normal_report.php");

Possible to add meta box to edit.php pages?

How to get the post content after Wordpress post processing?
I have a plugin that will send tutorial emails to our users. These tutorials are created in wordpress and stored in wp_posts table in the database.
Of course I could simply run a query to get the post and that's it. But is there a special built-in function that I can use to get the post content after Wordpress post processing?

<?php
$my_id = 7;
$post_id_7 = get_post($my_id);
$post_content = $post_id_7->post_content;
?>
Thanks for any tips. | If by "post processing" you mean the autoformatting, the shortcode processing, that sort of thing, then you want to pass the content through the `the_content` filters.

Multisite plugin hiding on specific blogs
Is it possible to hide plugins on a per blog basis in WordPress multisite? I would like not to have plugins available on certain blogs. | Super Admin is your friend! If a plugin is not active in the Super Admin (also lamely named Network Admin) Then it won't show up as an option for individual blogs.
**It basically works like this:**
Installed as Super Admin (main site) and "Network Active" will be active on all blogs on the network. Installed on Super Admin, Active but **NOT** "Network Active" only active on Main/Parent site
If you want it only installed on a few sites then just manually install the plugins like you would normally do. Each instance of WordPress on a multisite is treated as its own site so installing a plugin on one site (with the exception of the main site) will not install it on the rest.
**EDIT:**
Based on your comments I would make sure that the user has the correct role to upload/activate plugins. You must create a user in each site individually or add an existing user to the site.

What am I missing? | Pagination in URLs only works for the "main" query.

The plugin author has stated following limitation on it.
# Limitations
This plugin does not work for weekly archives. The list with archive links is correct, but the links themselves do not include the category. So when used, WordPress will not filter the resulting page on the category. The technical reason is that WordPress does not apply filters when the links for weekly archives are generated, so the plugin can't change them. Perhaps this is fixed in a next version of WordPress.
I checked latest version of wordpress(3.5.1) to find out whether this version has added any filter for weekly url but it has not added yet :(

Thanks! | I'm not sure that this is a good idea, email is just not a good medium for emergency messages (who will see the email when you are a sleep or at the beach?), and if you want to monitor the site it is better done by external service which will probably be able to send you an SMS or make a phone call.
That being said, if you want to still send emails, you need to store the last error time in a separate file, and before sending a mail read the file and check when was the last time a mail was sent.

wordpress local host web login not working after port configuration

Possible to add a statement to a core file?

<?php
include('./admin-footer.php');
I would like to add an php include statement...
include('./custom-file.php');

Is there some way I can use to add this one line via a function without having to edit the core file?

How to add custom widget above admin_footer

include( plugin_dir_path( __FILE__ ) . 'quickpost/quickpost.php');

Is there a way I can specify where to place the code? I would prefer to work with the 'load-edit.php' action, but if that is not possible - it is okay with me. Thanks! | As far as I know you have 2 options.
1. Using `admin_footer` or `load-edit.php` and position with `absolute` or `fixed`, or use JavaScript.
2. If you creating a completely new posts screen (not a default posts, pages, etc), you can extend `WP_List_Table` class, specifically the `extra_tablenav` function.
For example:
class My_Custom_Table extends WP_List_Table {
function extra_tablenav( $which ) {
if ( $which == "top" ){
//The code that goes before the table is here
echo "Hello, I'm before the table";
}
if ( $which == "bottom" ){
//The code that goes after the table is there
echo "Hi, I'm after the table";
}
}
}

What are the Best Practises When Using AJAX in Plugin Development?
I am in the middle of creating a plugin and everything works fine with the AJAX calls but one question I can't seem to find the answer to is about best practise.
I route the AJAX calls through `/wp-admin/admin-ajax.php` and have my php functions in the theme `functions.php` script.
However, I've just thought that this doesn't seem such a good idea because what do you do when the user activates your plugin, do you need to create a function to write your code to functions.php on activation?
Similarly, what if the user changes theme?
Therefore, I was just wondering if there are other ways to do it or what is the common approach for this type of thing. | WordPress AJAX best practices are following:
1. Use `wp_localize_script` to declare JavaScript global variables;
2. Use `admin-ajax.php` script to handle all AJAX requests;
3. Use nonces and check for permissions;
4. Use jQuery Form plugin to submit forms.
Read 5 tips for using AJAX in WordPress article for more details.
> What do you do when the user activates your plugin, do you need to create a function to write your code to functions.php on activation? Similarly, what if the user changes theme?
You don't have to care about it. If you write your own plugin and it uses AJAX requests, then it has to be implemented only inside your plugin, don't write code into theme's `functions.php` file. | stackexchange-wordpress | {

I want to reset user's post meta after successfully login
I want to reset admin's meta value after login. It can be changed after login by admin via control panel, but I want to reset it after every login.
I used this code but it's not working:
function reset_dismiss_message(){
update_user_meta( get_current_user_id(), 'tgmpa_dismissed_notice', false );
}
add_action('wp_login', 'reset_dismiss_message');
I checked if and found it that the **get_current_user_id()** function is not returning user's ID as there is no data generated when wp_login action processing.
So how can I do this? | `wp_login` action passes 2 arguments `$user_login` and `$user`. The second argument is the object of `WP_User` class, which you can use to get user id from:
function reset_dismiss_message( $user_login, $user ) {
update_user_meta( $user->ID, 'tgmpa_dismissed_notice', false );
}

Create a WordPress administrator without access to back-end
My site recently got hacked, and all my admin users lost their administrator level access. But when I access mySQL database, I saw all the users still exist.
How can I create an administrator when I can access the database only? | Run this script in phpMyAdmin or whatever tool you use to access MySQL:
SET @user_login := 'justin_foell';
SET @user_pass := 'Q9xiHgzZ';
SET @user_email := '[email protected]';
INSERT INTO `wp_users`
(`user_login`, `user_pass`, `user_email`, `user_registered`)
VALUES
(@user_login, MD5(@user_pass), @user_email, now());
SELECT @user_id := LAST_INSERT_ID();
INSERT INTO `wp_usermeta`

VALUES
(@user_id, 'wp_capabilities', 'a:1:{s:13:"administrator";b:1;}');
INSERT INTO `wp_usermeta`
(`user_id`, `meta_key`, `meta_value`)
VALUES
(@user_id, 'wp_user_level', '10');
Replace the set values at the top for `@user_login`, `@user_pass` and `@user_email` with your own settings. Also, if your WordPress installation uses tables that start with a prefix other than `wp_`, you’ll want to replace that in the table names as well.

Adding a user's ID behind the <a> tag ref link address
Good day, everyone:

above code will be turning in to a link if the user id is 113 who clicked it, the address will become:
<a href=" this page</a>
Or, if you know an alternative to do so, please also let me know.
Generally, the purpose will be that a user will be directed to a page that with unified address but there will be a number equal to his id attached behind. every time, someone click the same link, in same page, will have the same effect on each user. **When a user click it, will be the CURRENT USER, who is a registered user.**
If anyone could tell me if I could create the page at the same time (if not exist), will be terrific!

}
add_filter( 'content_edit_pre', 'wpse89725_pre_edit_content', 10, 2 );

You can also try the `edit_post_content` filter:

$value = apply_filters("edit_{$field}", $value, $post_id);
// Old school
$value = apply_filters("{$field_no_prefix}_edit_pre", $value, $post_id);

Any way to include custom fields in WP_Query results?
Looking for a way to include custom fields in the output of WP_Query. I am managing a site where nearly every post type has a lot of custom fields defined and it would be much nicer not to have to run get_post_custom in almost every loop. | You may want to hook somewhere in the gazillion hooks available in **`wp-includes/query.php`**.

$custom_fields = get_post_custom( $posts[$i]->ID );
$posts[$i]->custom_fields = $custom_fields;
}
return $posts;
}
add_filter( 'the_posts', 'my_always_get_post_custom' );
In this way you will always have your posts custom fields at hand in your **`$post` object** without having to bother to look for them every time you are setting up a loop.

Mapping Subdomains in Wordpress to give the appearance of a localised site, best approach?
I am building a classifieds website and am using Wordpress for the functionality of user accounts, Paypal integration, custom taxonomies and of course super flexible custom post types for the listings.
I would like to be able to map a subdomain to a particular sub-site. For example: australia.somesite.com or brisbane.somesite.com and have it localise the site to that particular region.
Is there a clean-cut way of doing this with Wordpress, possible that someone else has surely already done this. | Sort of a vague question, but I think I understand what you're getting at. You'd need to use a Wordpress Multisite installation, which will effectively create localized blogs on a subdomain (brisbane.example.com, perth.example.com).
Using a single site Wordpress installation to do this is possible, using CNAME mapping on the domain, however this would not suit your goal as you won't be able to **post within the localized listing**.
To achieve the subdomain for category "effect", with the least amount of effort, you should use Multisite. I hope that answers your question.
A good rundown of getting Multisite going can be found at WPMUDEV. Hope this helps.

for example :
add_action ('comment_post','my_comments_js_function');// runs when comments are POSTED
and then
my_comments_js_function(){
// do your JS stuff.

theme path in javascript file
I need to include the path to my theme file within a javascript file. How would I go about this? I have already tried:
var templateUrl = "<?php get_stylesheet_directory_uri(); ?>";
function LightboxOptions() {
this.fileLoadingImage = "'"+templateUrl+"/img/loading.gif'";
this.fileCloseImage = "'"+templateUrl+"/img/close.png'";
this.resizeDuration = 700;
this.fadeDuration = 500;
this.labelImage = "Image";
this.labelOf = "of";
}
This does not give me the path, but just inserts `<?php get_stylesheet_directory_uri(); ?>` instead of the actual path. Any ideas? Thanks in advance! | What you're looking for is wp_localize_script function.
You use it like this when enqueing script

Show menu on page with all sub-pages and sub-sub-pages of that page

Fetch the latest post with attachment image
What I want to do seems to be simple but I can't get around it. I'd like to get the latest post that has an image attachment. A little help would be appreciated. Thanks
Lita | This is a tricky one. If you wanted to get the latest image attachment and display the post associated with it, you could use:
$attachments = get_posts('post_type=attachment');
$first_attachment_post = get_post($attachments[0]->post_parent);
To get the latest post, but only if it has an attachment, I think the only way to do it would be with two nested queries. For example:
$the_query = new WP_Query( $args );
while ( $the_query->have_posts() ) : $the_query->the_post();
$attachments = get_children( array('post_parent' => get_the_ID(), 'post_type' => 'attachment', 'post_mime_type' => 'image') );
if ( $attachments ) {
// Post output here will only be display if attachments are found

Theme thumbnail in dashboard
I'm not sure whether this question belongs here but I don't know where else to ask it : do WordPress designers/developers usually create a dashboard theme thumbnail when they completed the WP theme for their client? If so, do they put their own logo on it or a screenshot of the home page? | Thats entirely up to to you.

Creating shortcodes with user created forms

Fixing YARPP plugin FULLTEXT MySQL indexing

Does the 'nav_menu_css_class' filter accept 2 or 3 arguments?
I've been using the `nav_menu_css_class` filter in one of my plugins, implemented as:
add_filter( 'nav_menu_css_class', 'wbwcrf_nav_menu_css_class', 10, 3 );
function wbwcrf_nav_menu_css_class( $classes, $item, $args )
{
/* snip */
return $classes;
}
The filter clearly has 3 arguments in the code (source) yet someone using my plugin has told me they get the error `Warning: Missing argument 3 for wbwcrf_nav_menu_css_class()`.
So I looked at the codex documentation on `nav_menu_css_class` which has an example using 2 arguments, I changed my code to 2 arguments since I'm not actually using the $args argument and everything seems to be working fine.
But I'm still really stumped as to why the source has 3 arguments yet the codex has 2 and why I don't receive any error when using 3 arguments, yet someone using my plugin does. Anyone able to clear up my confusion here please? | I can confirm that this filter applied with 3 parameters as you mentioned in your snippet. The warning is very strange and shouldn't appear if WordPress core wan't hacked.
The best practice for this case is to request parameters, which are required by your hook. So if you don't use `$args`, so don't request it:
add_filter( 'nav_menu_css_class', 'wbwcrf_nav_menu_css_class', 10, 2 );
function wbwcrf_nav_menu_css_class( $classes, $item )
{
// ...
}
Another approach is to set default values for income arguments:

Noob Loop Question

<?php endwhile; ?>
<?php endif; ?>

Sorry for the question, is that I'm not very familiar with wordpress yet. Thank you! | If you want to check the number of posts on each page, you can use the `found_posts` method of `WP_Query` :

while ($portfolio->have_posts()) : $portfolio->the_post();
echo "<div>";
the_title();
echo "</div>";
endwhile;
endif;
wp_reset_postdata();
?>

How to use is_feed() to target a category feed?
`is_feed` (one of the many conditional tags) can be used to determine if the current query is for a feed.
But how do I use it to target all category feeds? (or tag or custom taxonomy feeds for that matter)
This doesn't seem right:
if (is_category()) {
if (is_feed()) {
// Code Goes here
}
}
And I have no clue as to whatelse I'd try. | If you want to determine if you are in a category feed, for example:
you can do so with
add_action('wp', 'mycheck');
function mycheck() {
if(is_feed() && is_category() ){
// do stuff
}
}
or
add_action('wp', 'mycheck');
function mycheck() {
global $wp_query;
if($wp_query->is_feed && $wp_query->is_category){
// do stuff
}
}
You can similarly check if you are in a tag feed, for example:
with `is_tag`.
You can then check if you are in a custom taxonomy feed, for example:
with `is_tax`. | stackexchange-wordpress | {

Cannot locate specific <a href> link/string using String Translation with WPML?

Sorting posts by custom field value in array
I have a custom field value that is an array and it has date as one of the values:
a:3:{s:4:"date";s:10:"03/06/2013";s:6:"target";d:1000;s:8:"currency";s:3:"USD";}
I'm trying to sort posts with this date but I'm having trouble doing it.
Here is my query:
$args = array (
'showposts' => -1,
'post_type' => 'project',
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_query' => array(
array(
'key' => 'date',
'value' => date('m/d/Y'),
'compare' => '>=',
'type' => 'DATETIME',
)
),
'cat' => $cat_id);
$posts = get_posts( $args ); | Sadly you can't.
You can't query based on serialized data and since you store the data in an array it is saved as serialized.
you should use a separate row for each field you want to query / sort based on.

Add class to DIV depending on page loaded
I'm designing a new theme and in my page template a have a section where an image is displayed . I would like this image to change depending on which page is loaded.
The section is a DIV like this: `<DIV class="ximage"></DIV>`
What I would like to do is to add a class to the DIV depending om page loaded and then style the class with background-image in CSS.
I know you can do this with for example body_class() if you want to add classes to BODY. But how do I do this with a DIV?
There will be quite a few pages in this theme, so ceate a template for each page seems wrong. | You might want to consider using the Wordpress function `body_class()`
<body <?php body_class($class); ?>>
Then you could use the body class as your current page reference.
This function is for example used by the Twenty-Twelve theme.
For a single post it will become
<body class="single single-post ...">
and for the home page:
<body class="home blog ...">
You can read more about this function in the Codex here:
<
**Edit:**
> I know you can do this with for example body_class() if you want to add classes to BODY. But how do I do this with a DIV?
You could use it in your `div` tag:

Display Something in the Header After All Styles are Loaded
I'd like to include a functionality in a theme that will overwrite styles from previously included CSS files. For this purpose, I need to be able to display a `<style>` in the header after ALL stylesheets have been displayed.
Is there a hook to do this? | Hook to `wp_enqueue_scripts` with a high priority number. For example:
function load_my_style_wpse_90225() {
wp_register_style( 'mystyle', get_template_directory_uri() .'/path/to/stylesheet.css');
wp_enqueue_style( 'mystyle' );
}
add_action('wp_enqueue_scripts','load_my_style_wpse_90225',1000);

Contact information footer
I am new to Wordpress but forced to create a website as a Wordpress template for my current employee (I am a front end developer, mostly build new systems/apps etc from scratch). Creating the template is no issue, but how do I go about making everything fully editable? For example the footer: it contains contact information and I would like information to be fully editable from within the Wordpress admin. Everything however seems to resolve around posts and articles... so, my first idea was to simply make posts and categorize those as "Footer" and then filter the displayed posts on the loop in footer.php by that category but that doesn't seem very logical. What is a more common approach? Widgets? If widgets is the answer, how exactly do those present themselves in the admin section?
Sorry for the long question :) | Another option is to create a new post type called "modules" or something to that effect. Then you can create as many of those as you like, for example, "Footer: Contact Information," "Footer: Social Media," "Header: Callout," etc, and you can use that post's ID to bring it into the designated spots in your template.
While the sidebar suggestion from Jacob is also good, if you have a lot of those one-offs, it can get pretty overwhelming to manage. By making it a post type, you can search it, you get a WYSIWYG editor, and you can add additional custom fields if needed. | stackexchange-wordpress | {

Theme URLs problem
I programmed a theme post (edit: probably that's the `single.php` template) which uses the function `get_userdata( $_GET['p'] )`. But the main admin reformatted urls to this: `~/author/gamelaster` (default is `?author=1`) and now this is not working correctly.
> How do I get the id of Author in this URL format?
Or
> how do I get user slug + get id from database?
But, I cannot use the standard author functions/post functions(get_ID etc). | If you are on an "Author" page, and since you mentioned `author.php` it seems that you are, `get_queried_object()` will give you the author data, which it seems is what you want.
Try:
var_dump(get_queried_object());

Dynamic content in a static page
I have developed some calculators (in php) for my website and I need Wordpress integration. The calculators have a form and, after submission, the result is shown. The result depends on a query in the database. **Is it possible to create "static pages" (at least static URLs) that provide to the user dynamic content?**
Just to clearfy, I want something like:
website/blog
website/forum
website/calculators
website/calculators/one
website/calculators/two
I heard about Pages, but I cannot include php code on it. Worth point out that the calculators aren't static, the result will change everyday. | You _do_ want static pages. The easiest way to do this, and a very good way even if perhaps not the only way, is:
1. Create one or more custom template files for your static pages. This is where your PHP comes in.
/*
Template Name: Calculator
*/
get_header();
// your calculator code
// Whatever PHP you have should work
// This is very minimal. You may want something more complicated.
get_footer();
2. Save the file as some name not on the reserved list
3. Create your static pages from wp_admin->Pages. Why creating the pages, save them with appropriate "Template"-- that is, one of the ones you've created. (Look in the right sidebar under "Page Attributes".)
This way, you can keep the calculator pages consistent with the other pages on the site. | stackexchange-wordpress | {

What is the purpose of $merged_filters?
Savvy WordPress user here, or at least trying to be. I have the hang of hooks and filters with the code in WP's plugin.php
The only thing I cannot seem to understand is the $merged_filters global. The value for a tag is unset when a filter or action is added.
However, when an action or filter is executed, the $merged_filters[$tag] value is set to "true".
What is the purpose of this?
Thank you | For those of you who may be wondering what this does - I have figured it out.
When a new function is added to an action/filter hook, it is added at the end of the array. However, WordPress specifies that those functions are to be executed by priority.
When a function is added, merged_filters is used to keep track of whether functions for a hook have been sorted by priority or not. merged_filters is checked on do_action/apply_filters to determine whether the functions should be sorted (by priority) or not before the hook is executed | stackexchange-wordpress | {

Plugin update, is a deactivation and activation done?
When a plugin is being updated via the automatic updater, is that plugin deactivated and then re activated when the plugin update is finished?
Also is a maintenance file created during theme and plugin updates, or only during core updates? | According to the source code of _wp-admin/includes/class-wp-upgrader.php_
**Single plugin update:**
add_filter('upgrader_pre_install', array(&$this, 'deactivate_plugin_before_upgrade'), 10, 2);
add_filter('upgrader_clear_destination', array(&$this, 'delete_old_plugin'), 10, 4);
It'll deactivate the plugin before upgrade and you need to re-activate it manually after upgrade.
No maintenance file generated
**Bulk Pluigns Update**
add_filter('upgrader_clear_destination', array(&$this, 'delete_old_plugin'), 10, 4);
// Only start maintenance mode if running in Multisite OR the plugin is in use
No deactivation before upgrade. The plugin status will be as what it was. So, if it is activated now, it'll still be activated after upgrade.
And maintenance file will be generated if running in Multisite OR the plugin is in use.

Best Practice: Remove data on deactivation or uninstall?
When is it appropriate to remove a plugin's settings? On deactivation or uninstall? | Remove data only on uninstall. Deactivating plugins can be done by mistake or in order to troubleshot some other problem and you don't want to make the plugin users to config everything again in this situation.
Think about your PC software, does it delete its data when it is being closed and become inactive? no, only when it is uninstalled. Same applies here.
Actually the uninstall option is relatively new and it was created specifically to have a point where you know it is safe to delete data. | stackexchange-wordpress | {

Utilize Function in Child Theme / Template File

require_once('../../plugins/events-and-bookings/lib/class_eab_event_model.php');

Also this is the best place for all your `require_once` calls.
One trick I would like to recommend for theme development approach:
Don't use direct `require_one` call to include your scripts. Instead of it, use `locate_template` function to load scripts. By using this function, all child themes will be able to override your scripts. So for instance, you have file called `utilize.php`, and it lies in `inc` folder of your theme, then instead of calling `require_once 'inc/utilize.php';`, call `locate_template( 'inc/utilize.php', true, false );`.
Now it will be possible to create `inc/utilize.php` file in a child theme and override parent file. | stackexchange-wordpress | {
