Displaying Only Certain Tags in Loop
**What I'm trying to do is alter the loop across my site so it will check the site URL so it will know which tag to display.**
For example, if I give some posts the tag "golfclubs", I want it to work something like this:
if ($_SERVER['HTTP_HOST']=="www.golfclubreviewdomain.com"){
// code here to display only the "golfclubs" tagged posts
}
In case the code above is incorrect for what I want, I just want to check the current domain to see if it is < and if so, display the posts that are tagged with "golfclubs". I would like this change to work across all themes, so I want to change this at highest level if possible so it will affect homepage, categories, etc. Is there a core file that I can use that will never be updated when I upgrade wordpress?
And my final question, what change do I make to display more than 1 type of tagged post? maybe something like "golfclubs" and "general"? | * Create a must-use plugin.
* Put it in `<docroot>/wp-content/mu-plugins/selective-posts.php`
* Following should be the code in `selective-posts.php` to filter specific posts.
function golfclubs_tag( $query ) {
if ( $_SERVER['HTTP_HOST'] === 'www.golfclubreviewdomain.com' ) {
$query->set( 'tag', 'golfclubs' );
}
}
add_action( 'pre_get_posts', 'golfclubs_tag' );
This way it would filter all the queries across the site for specific domain and it would filter the posts with specific tag.
If you want to add another tag in the query, you can edit the above code as follows:
function golfclubs_tag( $query ) {
if ( $_SERVER['HTTP_HOST'] === 'www.golfclubreviewdomain.com' ) {
$query->set( 'tag', 'golfclubs,general' );
}

How to display username and password after registration
When a new user registers for a new account, WordPress sends an email with the login information as usual. The password is auto-generated and stored securely in the WP database and the registration is handled by MemberMouse. MemberMouse defers all user authentication to WP's built in system so they don't do any of the generation themselves.
What I'd like to do is route this new user to a Thank You page that displays some information like instructions on what to do next and will also display the username and generated password on this HTTPS page that allows them to more easily login since emails often end up in the spam folder.
Is there an easy way to do this? | No as it will be insecure to do it. Being able to display the password to the user means that you store it as a plain text somewhere which is a big no no.
Emails ending in spam should not be relevant here as you should not send passwords in email.
(sure you can hack something to make what you want but the system is not built to support such a thing) | stackexchange-wordpress | {

How to add a tag above a category post that displays the category name in Wordpress
I am wondering how I can display the category name on top of each article on this page. For example, each of the articles on this page are from multiple categories. Preferably, the category name would appear above the article title and below the photo.
I tried some of the settings in the Scene theme to no avail. I am guessing I'll have to jump in the PHP and code in the action to display the category name.
Here is the URL for the website: <

scrolltop always 0, can't trigger script
While trying to add a jQuery trigger on scroll script to my child theme, I noticed it never triggered even though it was added. However after trying to figure out why the script wasn't working I used `document.body.scrollTop` to find it always returned a value of `0` despite having a larger scroll height.
I tried the same thing on the unmodified parent theme and found it also always returned me a `0`. So I'm assuming there is some style or script that is hijacking it. I've tried to hunt it down but no luck as of yet.
Is there anyway I can reset the scrolltop property via css / javascript or trigger my script on a different scroll trigger? | I guess
`body.scrollTop` is deprecated in strict mode. Please use `documentElement.scrollTop` if in strict mode and `body.scrollTop` only if in quirks mode.
So I would suggest you to use `document.documentElement.scrollTop`. also let us know when are you using this statement? show us full code and your console error if possible
Please try the below code edited with respect to your comment code and let us know what you see in console.
jQuery(document).ready(function ($) {
jQuery(window).scroll(function(){
var ScrollTop = jQuery(window).scrollTop();
if (ScrollTop > 100) {
jQuery( ".site-header" ).addClass( "scroll" );
console.log("above 100");
}else{
jQuery( ".site-header" ).removeClass( "scroll" );
console.log("below or equal to 100");

How do I load custom scripts and styles for a page?
Different pages often need different set of scripts and styles for them.
I use functions.php and construction like this to load scripts and styles:
function load_assets() {
wp_enqueue_style( 'styles', get_template_directory_uri() . '/css/styles.css');
wp_enqueue_script('main-js', get_template_directory_uri() . '/js/main.js');
}
add_action( 'wp_enqueue_scripts', 'load_assets' );
I know I can put some condition here like this:
is_page()
but is there a better way?
Suggestion:
Can wp_register_script() be used to target specific pages? | Yes, you may add conditional tags to the `wp_enqueue_scripts` action. See the examples below:
function load_assets() {
wp_enqueue_style( 'styles', get_template_directory_uri() . '/css/styles.css');
// loads on any 'page' post type
if( is_page() ){
wp_enqueue_script('main-js', get_template_directory_uri() . '/js/main.js');
}
// only loads on the page with a slug of 'home'
if( is_page('home') ){
wp_enqueue_script('home-js', get_template_directory_uri() . '/js/home.js');
}
}
add_action( 'wp_enqueue_scripts', 'load_assets' );

how to use wp_redirect inside a function

} | You do not get that error because it runs inside a function, but because the headers have already been send. This means your server already has send some information about the page to the client, thus is it unable to change it's headers (headers are the first thing that gets send). This mostly happens after something gets echo'ed.
There are a few things you can do to prevent this from happening:
* Choose another event that gets triggered before the headers are send
* Remove any echo'ed text or HTML before the redirect
* Check if there is no whitespace (spaces, enters, tabs) between the the start of your file and the `<?php` tag.
* Change your server configration to send the headers later (this can be tricky or inpossible). | stackexchange-wordpress | {

How often do you need to register_post_type?
Assuming you write a plugin and hook into activation / deactivation to register_post_type is that good enough? Or do you need to do it every init?
I'm looking for perf boosts and I want to reduce unnecessary calls.
GenerateWP uses `add_action( 'init', 'custom_post_type', 0 );` so that might be as early as I might want to register it.
**FINDINGS**
* @s-ha-dum:
> `register_post_type` needs to be called on every page load
>
> The `post` data itself is kept in the database, but the registration tells the PHP what to do with it.
* @pieter-goosen:
> Build in types are actually registered twice on every page load (due to localization that is only available on `init`) | `register_post_type` needs to be called on every page load-- `init` seems to be fine and is the hook used in the Codex sample. The post data itself is kept in the database, but the registration tells the PHP what to do with it. Most of the post type information-- the `$labels`, the `$args`\-- are not kept in the database to my knowledge (though I would agree that there _might be_ an argument for doing so), so without that registration code Core doesn't really know about the post type.

Theme Customizer - Text without a setting (a comment or <p> tag)
In the Theme Customizer, is it possible to just have text (for example a comment, or a HTML `<p>` tag with text), or a setting that has no type (but a title of `Text I need to display`).
For example, I may want to say - `Go to XXX to do this` at the bottom of a section, or `Find out more in the documentation`
I know you can have descriptions on settings but that is not what I want (unless the setting itself is invisible). | If I understand the question right, the easiest way to implement this now is to create a new control type that doesn't actually render any input but rather just displays your desired text. Controls have to have an associated setting, so you can register a setting with a custom type of `noop` so that it will not have any effect. Give the control a high priority so it will appear at the end of the section.
A more elegant solution would be to create a custom section that has this end matter as part of its template. Unfortunately, the `ul` is currently expected to be a direct descendent of the section container, so this is problematic. | stackexchange-wordpress | {

Solution dealing with Child Theme / Parent theme functions
This week I was struggling a bit customizing an exsisting theme for a client. To prevent the theme from being overwritten each update I created a child theme. This allowed me to cusomize most of the files that handled templating. The function which loaded additional stylesheets and js libraries was pluggable and could be overwritten.
The biggest problem I faced was to overwrite some of the core functions of the theme. These were not pluggable (did not use the if(!function_exsisits()) statement) and didn't use a hook or filter. Calling the same core function from the child theme functions.php or a custom plugin threw a fatal error (function cannot be redeclared). | My solution to this issue was to create a custom plugin with copies of the core functions needed to be overwritten. I gave these functions custom names so I could call them from the template files in the Child Theme directory. Now I could add my own code and modifications and leave files with the core theme functions intact.
This creates some redundant code, but now I can use a child theme and 'overwrite' core theme functions until the theme author makes the original core functions pluggable. | stackexchange-wordpress | {

Wrong slug on blog page
<?php

This code is used after `<head>` and before `<body>` and is supposed to get current page's slug. It works great, however it will get the _slug of first blog post_ when on _"general"_ blog page.

* Blog url: `www.my-site.com/blog/ ->` slug in admin area is set to `blog`
* Blog post url: `www.my-site.com/post-1/ ->` slug in admin area is set to `post-1`
Code echoes `post-1` for both. **Any ideas?** | > This code is used after `<head>` and before `<body>` and is supposed to get current page's slug. It works great, however it will get the slug of first blog post when on "general" blog page.
`$post` is going to be set to the first post in the Loop when the page loads. On "page" pages with only one post in the Loop that is going to be the page data you expect. On archive pages it will be the first post in the set of posts on the page. This is what appears to be happening. You can't trust `$post` explicitly like that-- that is, without understanding exactly when it is set to what. (Most loops, even secondary ones, will alter this variable as well)
To get the page data itself you need `get_queried_object()` but be careful with that too as it will be different on various types of pages-- sometimes a post object, sometimes a user object, sometimes `null`. | stackexchange-wordpress | {

You need to loop over the results and run `get_comment_meta()`, or essentially do the same via a filter on `the_comments`.
It is also possible to add to the data returned by filtering the "fields" clauses:
function add_cmeta_wpse_212423($clauses){
// var_dump($clauses);

$meta = "(SELECT meta_value
FROM {$wpdb->commentmeta}

Wordpress Redirects on Install

* wp-includes/
* wp-content/
* s/

In the UNU website under the Experts section (< there's a form where you can filter the experts by their institute and expertise area.
This is what it looks like: ![enter image description here](
I understand that the experts are stored in custom post types "expert". But I don't understand how the search form is built so that users can filter experts by selecting their institution and research topics?
Specifically:
* How to build data structure into the `Expert` type, i.e. how to link an expert with attributes like "institution" and "research area"?
* With the above data structure built, how to include a filter for `Expert` listing as shown in the screenshot above?
I would appreciate if you could explain the general idea how it's implemented; or is there a plugin so I don't have to reinvent?
Thank you. | > How to build data structure into the Expert type, i.e. how to link an expert with attributes like "institution" and "research area"?
**Answer**
You may use Taxomonies in wordpress, to add extra level od categorization of your posts. In your example, you may register `Institution` and `Research area` taxonomies for your `Experts` custom post type.
> With the above data structure built, how to include a filter for Expert listing as shown in the screenshot above?
**Answer**
You may use an ajax call to pass the filter criteria and receive related experts from the server. | stackexchange-wordpress | {

How can I get the permalink of a page on which shortcode has been used
I want to redirect users to a page on which a particular short-code has been used after they login. So basically I want to know how can I get the permalink of that particular page on which my plugins specific short code has been used? | I think that the very best approach would be to store that page on a option.
Anyway, if you want to get the pages where a shortcode has been used, you can use the search parameter (`s`) of `WP_Query` class (or `get_posts()` function). Basically, this parameter performs a `LIKE` query, so it could be useful to search for shortcodes like this:
$args = array(
's' => '[myshortcode',
'post_type' => 'pages'
);
$pages_with_myshortcode = get_posts( $args ); | stackexchange-wordpress | {

How to modify single.php in a child theme?
My WordPress site uses a child-theme (of the default twenty-sixteen) and now I would like to insert a new line into the `single.php` file.

I would be grateful if somebody could show me how to do it properly. I would like to insert this line
<div class="fb-comments" data-href="<?php the_permalink(); ?> " data-numposts="5"></div>
into the
<div id="primary" class="content-area">
element, right above the closing
</main>

Filter by custom field in custom post type on admin page

Restricting text field to numbers only in Gravity Forms
We're trying to restrict a text field to numbers only. Here's what we've tried
* Add text field
* Apply input mask (9999999999)
The problem is that if someone does not fully complete the field, the number is erased when they tab into the next field or if they click anywhere outside of that field. It should not matter how many characters they put into the field, it should just restrict the field to a number.
If one only puts one 9 in the field, it restricts the field to 1 number. With the input mask set to ten 9's, you can enter 10 numbers. The problem is that if you do not enter the exact number, it clear the field once it loses focus.
We can do this with jQuery but we're hoping that Gravity has a hidden gem we've missed somewhere?
![enter image description here]( | If you add a question mark before your string of 9s, this will work as desired. It makes the completion optional. It will still enforce a max limit based on the number of 9s you have but there will be no minimum limit.

What WP-API authentication method should I use to interact with anonymous / not-logged visitors?

I was going to make an AJAX request to the `wp_ajax_$action` and `wp_ajax_nonpriv_$action` hooks but I'd like to use this small task as an opportunity to experiment with the new REST API since I heard it is going to replace the old `wp-admin/admin-ajax.php` way of doing it on the long run.

WP Query crashes on more than ~ 2000 posts
Hello there for a custom post type "organizations" I have about 5000 posts which have to be shown in a list with link within one page.
However WP_Query just crashes (without PHP timeout just after 4 seconds on the server). Is this a WordPress problem? If so, why do they limit it? Or is it definitly a server problem?
$q = new WP_Query(array('post_type' => 'organization','posts_per_page' => 9999)); | Querying this many posts is dangerous and you can ( and do ) take the site down. If you absolutely have to do this, you need to adjust your query to be more performant.
If you're just needing the link then add `'fields' => 'ids'` to your params - this will only return the post ID and not the whole Post object. You can then use the ID to get the permalink, title etc.
If you're not going to paginate, then use `'no_found_rows' => true` this will stop WordPress from running expensive SQL CALC queries to get the total number of posts that the query retrieves.
You should 100% cache the results of this query using the Transient API this will allow you to return cached HTML instead of rebuilding this query every time someone hits the page. | stackexchange-wordpress | {

How to get all logged in user id in buddypress

$bp->loggedin_user->id
But this is not helping.. Please help me to get all logged in user id. Thanks. | This `$bp->loggedin_user->id` will only give you a single id, of the _current_ logged in user. btw - it also requires use of the `$bp global`. You don't need to use that global. Use `bp_loggedin_user_id()` instead.
BuddyPress does not track logged in users. It does not use sessions. It does use timestamps in the database to indicate recent activity. So you could use custom sql to return user ids. For example:
function shahid_get_recent_active() {
global $wpdb;
$time = time() - (60 * 10); // current time minus 10 minutes
$cutoff = date('Y-m-d h:i:s', $time);

$custom_query_args = [
'post_type' => 'post',
'post_status' => 'publish',
];
// Add filter
add_filter( 'posts_where', 'wpse_where' );
// Query
$custom_query = new WP_Query( $custom_query_args );
// Remove filter
remove_filter( 'posts_where', 'wpse_where' );
where our custom filter callback is:
function wpse_where( $where )
{
global $wpdb;
return $where . " OR (
{wpdb->posts}.post_author = 2
AND {wpdb->posts}.post_status = 'publish'
AND {wpdb->posts}.post_type = 'post'

The problem is that the code stops working when you move the code to `functions.php`, which is a **_theme_** file. The theme loads after plugins load and hence after `plugins_loaded`. Take a look at the hook sequence for a typical page load: <

How to check custom fields from functions.php
I'm trying to hide certain menu items based on the custom fields on a page. I could use CSS or a script to hide the items, that's not the problem. What I don't know is how I can check the custom fields (if field empty then hide item) in my functions.php.
Any ideas? | I don't know if you need to hide the element completely, as in "never display it", or if you need to hide it conditionally with JavaScript-- say, to get a toggle effect. Either case is similar and would use `get_post_meta()`.
To conditionally display the data use something like:
$m = get_post_meta(get_the_ID(),'my_meta_key');
if(!empty($m)) {
echo '<div>your data</div>';
}
If you want something that you can toggle with JavaScript use:
$m = get_post_meta(get_the_ID(),'my_meta_key');
$str = '<div %s>your data</div>';
if(!empty($m)) {
$str = sprintf($str,'class="'.$m.'"');

Taxonomies within plugin invalid
I have two taxonomies being registered in a functions file. They are then initialized like so:
function foo_register_post_types_and_taxonomies() {
foo_register_post_types(); // defined in lib/post_types.php
foo_register_taxonomies(); // defined in lib/taxonomies.php
}
add_action('init', 'foo_register_post_types_and_taxonomies');
The problem is that within a plugin i'm building, those two taxonomies are invalid. I think from what I've been reading is that the plugin runs before the taxonomies have been initialized? How do solve this so I can access these tax's from within my plugin?
In other words, outside of the plugin in any template file, when I run **get_terms('school')** , I get an array of terms for the taxonomy 'school'. Running this same code within a plugin returns invalid taxonomy. That's my problem in a nutshell. | Your taxonomies register where you've told them to register, on the `init` hook which is the recommended hook for registering them. That much you are doing correctly.
And yes, the plugins themselves will load prior to that hook's execution. You can see that by comparing the `init` hook's location in the load sequence to the `plugins_loaded` hook's placement.
You don't say exactly what you are trying to accomplish but the trick is that any code intended to access your taxonomies needs to run on the `init` hook (possibly with a higher than normal priority) or on a later hook. | stackexchange-wordpress | {

Delete post meta conditionally after save post

// WP edit function
wp_inline_edit.apply(this, arguments);
// get post ID
var post_id = 0;
if (typeof( id ) === 'object') {
post_id = parseInt(this.getId(id));
}
if (post_id > 0 && typeof mp_data !== 'undefined' && $.inArray( post_id, mp_data.ids ) > -1 ) {
var edit_row = $('#edit-' + post_id);

Change setting name in Customizer and keep the data
I created a theme while back when I was new to Customizer API and for some weird reasons I named theme settings as:
`$wp_customize->add_setting('thefunk_theme_options[header_color]`
Instead of just `header_color` and saved every setting in an array like `thefunk_theme_options[header_color]`
So I recently found out that it's generating some issues, so I want to save every setting, let's say, `thefunk_theme_options[header_color]` to `header_color` or `thefunk_header_color`.
Now I know how I can change the settings in the Customizer. However, it will affect everyone who is currently using the theme. All the customization will be gone, so does any one know how I can import the data from the old tables and add it to the new tables? | Personally I think keeping your mods in an array is a nice solution, but transferring them shouldn't be too difficult. Just loop through the array like this:
$all_mods = get_theme_mod('thefunk_theme_options'); // retrieve array
foreach ($all_mods as $key -> $value) {
if (!empty($value)) set_theme_mod ($key,$value); // set array element as separate mod
}
Since you have to do this only once, when the updated theme is ran first, you may want to insert an extra check upfront and delete the array afterwards. | stackexchange-wordpress | {

Page naming when there is a sub-category only sometimes.
I need help with understanding page naming to display a sub-category which only occurs only sometimes. I also need to understand if I need to create a custom Taxonomy to achieve this? I am using CPT UI plugin.
I have a CPT, called APPLES.
All of my main apple parent types are displaying as images on archive-apple.php. (maybe this should be page?). I will then click on the image of the parent apple type I want to know more about and I will see a sub-page of images/information about that specific kind of Apple.
BUT, Sometimes that individual Apple parent will have two or three variations of the main parent Apple. So an intermediary page with two sub-type images must display giving me the choice of what sub-type I want to see.
Here is a diagram to explain what I am trying to do. Please and thank you for any help.

register_taxonomy(
'apples_category',
'apples',
array(
'label' => __( 'Apples category' ),
'rewrite' => array( 'slug' => 'apples_cat' ),
'hierarchical' => true

);
}
add_action( 'init', 'add_apples_cat_taxonomy' );

Change url-structure for wordpress pages - pages in strucutre not top-level

The system doesn't work that way. Menus structure and URL structure are not tied together. You could probably alter permalinks such that this would be the case but it would be a complicated project and potentially cause substantial strain on server resources.
The simplest thing to do is to create nested pages via the backend.
1. Create a page called "Services"
2. Then create all of the other pages as children of that "Services" page.

There is a static page with a next button on it. The next button is responsible for pulling the next section and displaying it to the user.
After analyzing data, the flow is something like this:
1. Click on "Next" button.
2. POST /section-viewer with two parameters, "next_section_id: 3451" and "hash: 345345"
3. POST responds with page HTML as its body -- which is the full page of the next section, 3451.
I have found bits and pieces of the HTML being generated, but I am not able to figure out the final response, and where/how Wordpress/PHP responds to the POST.
What I'd like to do is instead of sending the next page's HTML as the body of the POST response, is send redirect, and then redirect the user to the page that has the HTML there. | The answer is, anything that is `echo`d after the POST request, is sent back to the requester via the RESPONSE body.
Thus any `echo` statements issued after processing whatever was sent via the $_POST is generated and sent back. In this template's case, it would be better to re-direct the user immediately to a new page, instead of echoing contents back. | stackexchange-wordpress | {

How to update custom taxonomy meta using ACF update_field() function or any other wordpress function
I'm trying to update the Advanced Custom Fields meta value associated with a custom taxonomy term
$term_status = wp_update_term( $rate_id, 'rate', $term_data );
$term_id = $term_status['term_taxonomy_id'];
update_field( 'field_56829855eebc9',$rate_daily,$term_id );
However, I'm not getting the field updated. I have tried the field name instead of the field key too. | I figured it out somehow..
Syntax of `update_field()`:
`update_field($field_key, $value, $post_id)`
MY MISTAKE: I was using the wrong parameter for the `$post_id` which i thought was the Term Id of the custom taxonomy term.
CORRECT USAGE: rather than using term id (`$term_id` in my question), one should use a string with the taxonomy preppended to the $term_id
ie `$post_id` = `$taxonomy.'_'.$term_id`
for eg: if your custom taxonomy is `foo` and the term id is `123`
then : `$post_id = foo_123`
Hope this is helpful for someone.

Don't show avatars in media library
I am letting users upload avatars which are stored within the uploads folder inside the avatars subfolder which I created.
The problem is that avatars are now listed in the media library among other uploaded images.
How can I prevent that?
I was looking for a filter to filter out what is being displayed but couldn't find one. I wouldn't mind the avatars folder being outside the uploads folder if it has to. | Like most page loads in WordPress, `WP_Query` is intimately involved meaning `pre_get_posts` is your friend. Proof of concept:
function step_2($qry) {
$qry->set('post__not_in',array(468,303));
}
function step_1() {
add_action('pre_get_posts','step_2');
}
add_action('load-upload.php','step_1');
I'm using the `load-upload.php` hook to isolate the filter to the "Library" page. If you've changed the uploads folder for your avatars you've already got some "upload" code in place. You will need to extend that to track your avatar IDs and retrieve them instead of hard-coding as I did. It might be possible to use some other mechanism to filter the results as well.
While I haven't tested this, if you were to upload as some other post type than "attachment" the rest would probably fall into place without further effort. | stackexchange-wordpress | {

Buddypress avatar image in database
I want to get path of buddy-press profile pic directly in database to be used on other then word-press platform but i am not able to find it in database.. because i can't use buddy-press functions in other platform or language.i am using only buddypress databse.
Please help Thanks | BuddyPress does not store the avatar path in the database.
It loads avatars using the directory path - usually `.../wp-content/uploads/avatars/`. For example, the full sized avatar for a member might be `.../wp-content/uploads/avatars/1/ef1e70a512662ea4fdca5b2efb6f76ab-bpfull.jpg` where `1` is the user_id.

Get product link
I want rating from customers by sending mail after order is completed. If customer will click link on mail for review it should redirect to same current product page of my site.

Use register_taxonomy() in register_activation_hook()
I would like to use `register_taxonomy()` to define a hierarchy of geographical terms. It seems that the natural place to place it would be in a function called by `register_activation_hook()` seeing how the taxonomy needs only to be defined once. However, the fine manual explicitly states to "use the init action to call this function".
Why? Is the data not stored in the database but rather in memory? If so, might such taxonomies become memory hogs? I cannot anticipate where the end user might use the taxonomies to target anything more precise than init. | > Is the data not stored in the database but rather in memory?
Taxonomies (like post types) aren't store in database and needs to be registered on every page load. The build in taxonomies, `category` and `post_tag` are actually registered twice, the second time on the `init` hook.
The `init` hook is the earliest to register taxonomies and post types because this is the hook where localization becomes available. This has become the accepted hook to register post types and taxonomies.
> If so, might such taxonomies become memory hogs?
No. If you are going to register tons of taxonomies (or post types) it might become an issue, but doing that would point to a flaw in your design.
Terms on the other hand needs to be be registered once as they are stored in db. Here the `register_activation_hook()` is useful to register terms on plugin activation. Here is an example on how to register terms on plugin activation | stackexchange-wordpress | {

c) Enqueue Script

Publishing Markdown posts from bitbucket to WordPress
I have a lot of markdown documents stored in a BitBucket repository. The md documents change often so I use it to track changes.
I was now playing with the idea to 'publish' these MarkDown documents to a WordPress site.
Is it possible to setup a continuous deployment of MarkDown documents to a WorPress site. And if so, any pointers on how to get this started?
Thx, | It is possible although it would take quite a bit of initial setup.
I recommend learning about Bitbucket's webhooks. This is how you would have Bitbucket essentially talk to your WordPress install. You would create a plugin or a theme template that has a physical url to it that you point the webhook to.
When a commit is made, bitbucket will send a payload to that url and a php script will update the existing post in the database based on the changes made. If it is a new markdown file, a new post is created, if the post already exists, it will update. This would of course be the hardest part of all of it.

How to stop wrapping comments in P tag
When I update a comment in wordpress, the comment is wrapped with p tag.

remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );
remove_filter( 'pre_comment_content', 'wp_filter_kses');
return wp_update_comment( $data );
I removed the `wpautop` filter but the problem didn't disappear. Does anyone know how to solve this problem? | Comments aren't part of the post body. Those won't be effected by the filters that you are trying to use. The core front end comment filters are these:
146 add_filter( 'comment_text', 'wptexturize' );
147 add_filter( 'comment_text', 'convert_chars' );
148 add_filter( 'comment_text', 'make_clickable', 9 );
149 add_filter( 'comment_text', 'force_balance_tags', 25 );
150 add_filter( 'comment_text', 'convert_smilies', 20 );
151 add_filter( 'comment_text', 'wpautop', 30 );
You will want to do something like:
remove_filter('comment_text','wpautop',30);
With `remove_filter()` the priority hook isn't when `remove_filter()` runs, it is the priority of the callback that you are removing. It has to match. | stackexchange-wordpress | {

Conflict with single and double quotes

esc_attr__( 'Default', 'my_theme' )

How to determine the template loaded when you are not an Admin?

WP plugin calls for custom pages
I'm trying to create a custom landing page for my site. I am using wordpress because of the SEO plugins they offer. Mind you I'm not an expert so this might be an obvious question (please be gentle)

[EDIT]
I was asked for clarification so hopefully I am able to clarify my question a bit. I want to include my wordpress plugin in a custom landing page I'm hand building (coding myself). To include these plugins, would I do calls somewhere in my custom code for the landing page? What do I necessary have to do? Hopefully this is a little more clear. Thanks guys :) | You don't have to "include" plugins. Plugins operate, or **_should operate_** , by means of the extensive "hook" system built into WordPress core. Once activated, a plugin should not require much else (with a few exceptions for very complicated plugins).
What you need to do is make sure that you are using the appropriate Core functions classes to generate content-- such as `get_header()`, `get_footer()`, `the_content()`, `the_title()`, `WP_Query`, `get_template_part()`. It is a very, very long list.
