Manually return false for function_exists
I'm having a run at developing a theme options plugin and right now working on implementing a 'hero' header, checking first to see if my plugin is active using:
if( function_exists( 'my_header_function ) ): my_header_function();
else:
/* carry on and output the default header... */
endif;
Now as my hero header depends on whether the image and logo have been uploaded I wonder if I can manually return a 'false' result from my hook in order to have the original conditional in my header carry on an output the normal header.
Any ideas? Many thanks. | Have your function return your HTML rather than echo it. Perform the logic in the function to see if the image/logo are present and only return the HTML if that's the case, otherwise returning null/false.
function my_header_function( $output = false ) {
if ( /*image and logo have been uploaded */ ) {
$output = /* HTML of your hero header */;
}
return $output;
}
Add a check to your hook function to see if your function returns content; if it does, echo it.
if ( function_exists( 'my_header_function' ) && ( $hero = my_header_function() ) ) {
echo $hero;

Can you run wordpress with multiple domains at the same time (not multisite)?
Every now and then some clients have multiple domains for the same site. For example domain.com and domain.org. Is it possible to have wordpress work with both domains at the same time? I typically see issues when trying to load resources because of Cross-domain access. I know that I could just point domain.com to domain.org in the domain settings, but I was wondering if that's the only way.
I searched for solutions here, but all questions are about how to setup multiple domains for multisites (which makes sense). Just to be clear, I am not running a multisite. | Are you wanting for the exact same WordPress site to work on two different domain names, where all links and content would use either domain name?
If this were the case, you would run into Duplicate Content issues with Google, hurting your SEO pretty badly.
That being said, you still would have a very hard time getting WordPress to properly load your content off of either domain name. A variety of functionality uses the get_site_url function to construct the links on your pages, so all of your links would be using only the one domain within your Siteurl setting.
Even still, if you want to try and get really tricksy, you can use something like the following to define your Siteurl and Home in the wp-config.php based upon the Domain being passed to the site:
define('WP_SITEURL', ' . $_SERVER['HTTP_HOST'] . '/path/to/wordpress');
define('WP_HOME', ' . $_SERVER['HTTP_HOST'] . '/path/to/wordpress'); | stackexchange-wordpress | {

Merge comments from Facebook with WP comments

Questions about using Disqus or Jetpack for comments
I'm looking for a good commenting plugin, I want to choose between Disqus and Jetpack, but I have a few questions I **couldn't** figure out myself.
Hopefully you guys can help me out! :)
1) Where are the comments stored, is this in my database on or the Disqus/jetpack server?
2) What will happen if I switch over to default comments after all, will the Disqus or jetpack comments be removed?
3)Facebook is really important, while loggin in on Jetpack/Disqus, will these comment show up on facebook (in the activity feed of their friends) as well? Like normal facebook comments in wordpress?
4) Same with twitter, is there an option to share the comment on Twitter?
Hope you guys can help. Thanks. | I am using Disqus and can anwser for this platform :
1) You have the option to save comments both on Disqus and locally on WordPress.
2) This way, if you want to switch to default comments, they will already be there. On the other side, you cal also import local comments to Disqus, if you were using the default comment system and want to switch to Disqus.

Hide a category of posts from main blog, and only show in category view
I would like to hide a post on the main blog page (run on index.php) and have it only show up when the visitor views a particular category.
I have tried the following just before the loop:
<?php query_posts('cat=-208'); ?>
This hides the post in blog view as intended, but when I click into category 208 all posts show up there, even those not tagged with that category. However, the post tagged with that category does not show up there either.
Please help. | I was able to get the result that I wanted by putting the following into the `functions.php` file in my theme directory:
function exclude_category( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
$query->set( 'cat', '-208' );
}
}
add_action( 'pre_get_posts', 'exclude_category' );
The result of using this code was that any posts tagged with category 208 do not appear in the main blog, but they do appear in category 208 as well as in any other categories they are tagged with.
To exclude multiple categories, edit the following line of the above as follows:
$query->set( 'cat', '-208,-9,-50' );

How to Display a Single Post Excerpt
Is it possible to show the excerpt for a known and single post (on the Home Page) while in `the loop`?
I tried each of these and none of them work:

if ( $_post = get_post( 10 ) ) {
setup_postdata( $post = $_post );
the_excerpt();

What could interfere with changing iframe contents with href?
On one v4.1 Wordpress site the following code works as expected:

<iframe src=" height="1000" name="test" id="test"></iframe>

How can I determine what's breaking the reference to the iframe, or the hyperlink functionality, on the second site? | Ah ha: by searching the rendered page for `target` I discovered that the site was running a plugin called "Open external links in a new window."

Return only Count from a wp_query request?
Is it possible with the standard build-in tools in Wordpress to get `wp_query` to only return the count of an query?
Right now, I’ve a query which has several meta_queries but what the only thing I’m interested in is the actually count of the query.
I know that I can use the found_posts property but the query itself generates a big overhead by query `SELECT *` and thus returns the whole object.
I could just as easy query the DB with a custom query using `$wpdb` but I would like to utilize the build-in query system if possible..
I’ve been looking for the answer for this on SE and Google but came on empty.
If I've explained myself poorly, please let me know and I'll try to elaborate.
Cheers | There is no build in function to achieve what you want, at least not for complicated meta queries like this. If you need to use build in functions for this, the best will be to make use of `WP_Query`.
To make the query faster and to skip the unwanted returned array of `WP_Post` properties, and because you are only interested in post count, you can use the following in your parameters in your arguments
'fields' => 'ids',
'no_found_rows' => true,
This might even be a bit faster than a custom SQL query, and the results from `WP_Query` is cached as well. | stackexchange-wordpress | {

How to sync user database with "user role editor" plugin enabled
I already know how to sync user database for multiple wp installations from this answer. I don't know how to sync user database with custom user roles.
Thanks in Advance! :) | User roles and associated capabilities are all stored in the `$prefix_options` table in the `$prefix_user_roles` (note that in both of these `$prefix` is a variable, so if your `$prefix` is `foo_`, your table will be `foo_options`). You need to sync this value between databases. As far as I'm aware, there is not a way to sync just this one option beyond connecting to the needed table for it.

add_meta_box creating default form field types
I'm using `add_meta_box` as per the Codex entry.
My question is about the 'callback' to print the form fields on the admin page.
In the Codex, the form fields are echoed as written out HTML elements, but in some plugins I've looked through, the developers prefer to use 'callback_args' to pass an easy to understand array to pseudo-form elements that is then processed to output the HTML elements with minimal HTML coding. See, for example, this code on GitHub. WooCommerce also has a similar way to build meta boxes for products.
So my question is: does WordPress by default have a similar mechanism or is that a feature that requires a plugin? | Short answer: no.

Term specific featured post on taxonomy archive pages
I am trying to find a way to display a per term featured post on taxonomy archive pages.
So say you navigate to `url.com/my_taxonomy/my_term` it should show the featured post of `my_term` above the results of this page.
Making a post "`featured`" would be done by a custom field named "`featured`", which is a true/false field.
**Edit: the way to go...**
<?php
$obj = get_queried_object();
$post_object = get_field('featured', $obj );
if( $post_object ):
// override $post
$post = $post_object;
setup_postdata( $post );
?>
<div class="featured">
</div>
<?php wp_reset_postdata(); ?>
<?php endif; ?> | The way to go would be to create an archive template for your **taxonomy**. Then you can catch the term requested with a function like `get_queried_object()`. So now you can do a custom `WP_Query` querying for both your term and your meta 'featured'

Categories' hierarchy in URL

Thank you. | The permastruct `/%category%/%postname%/` will include the categories and subcategories in the URL **from top to first assigned child**.

error in wp_title on year archive - undefined index 00
In the year archive page in the title tag i get
Notice: Undefined index: 00 in wp-includes\locale.php on line 271

Add HTML to single post <head> tag
If I have developed a separate HTML page that I wish to include inside my Wordpress site what is the best way of including it? In this case it requires a javascript library or stylesheet that is not by default in my Wordpress theme that would need to be inserted in the tag.
I am aware of the following solutions:
iFrames:
* To match the site styling I would need to include every css from the theme in the iframe header.
* If the theme is updated with another script style sheet, this would not be updated in the iframe, maintenance could be arduous.
Editing the theme:
I could add into the various theme files along the lines:
is_single( 'page1' )
add_action( 'wp_head', 'extra_stuff' )
For each post/page I create or change I would have to change the theme files accordingly.
Ideally I would like to be able to do this from within the post editor
Are there any plugins that accomplish this? | I found the best solution was to add a custom field, `head`, and then build a short plugin to add the contents to the head tag:
add_action('wp_head', 'add_HTML_head');
function add_HTML_head(){
global $post;
if(!empty($post)){
// get custom field for 'head'
$headHTML = get_post_meta($post->ID, 'head', true);
if(!empty($headHTML)){
echo $headHTML;
}
}
}

Authentication / login mechanism (non wp-admin)

List subcategory on taxonomy term page
On WooCommerce I am using the archive-product.php template page. I want to show a list of the sub-categorys from the displayed category.

Help diagnosing scheduled post problem with transition_post_status
I've messed with trying to get scheduled posts to fire a function for months and finally stripped things down to the following code to see what is happening. The problem is that a scheduled post will not show the wp_die.
add_action( 'transition_post_status', function ( $new_status, $old_status, $post ) {
if( 'publish' == $new_status && 'publish' != $old_status ) {
wp_die('STOP');
}
}, 10, 3 );
If I simply immediately click on post then the STOP shows but a scheduled post shows nothing and will publish. I've also tried simply wp_die($post); to see what is returned on a scheduled post and there the wp_die isn't fired.
Even forcing this to 'future' == $old_status does not work.
How can I diagnose why this isn't firing for scheduled posts?
I've tried var_dump as well. | By default `add_action()` only passes one parameter, not all three. Change your function to:
add_action( 'transition_post_status', function ( $new_status, $old_status, $post ) {
if( 'publish' == $new_status && 'publish' != $old_status ) {
wp_die('STOP');
}
}, 10, 3 );
**Edited to add:**
The `transition_post_status` hook fires after the post transition from future to publish has occurred, and calling wp_die() will not display 'STOP' for scheduled posts. Instead you will just prevent the remaining actions in `wp_transition_post_status()` from being processed.
Future posts are published with background scheduled events via wp_cron, so calling a function like `var_dump()` or `print_r()` will not be useful for debugging.

Show Image Size as Dragging it Larger or Smaller
I've searched everywhere for this, but no luck! I think I must be hallucinating.
I thought previous versions of Wordpress displayed the size of the images in the visual editor as you dragged them to be smaller or larger. As in, you would pull the corner of the image inward or outward, and the "live" size of the image would show above the image as you dragged it. In other words you could see what size the image is as you make it smaller or larger, and that size is what gets printed in the HTML.
Does anyone know if this "live image size display" exists in Wordpress' coding, or if there's a way to get something like that working? Am I hallucinating? Thank you! | This is a screencast from my WordPress 4.1 install:

EM in CSS different size on wordpress then elsewhere

font-size: 1rem;
line-height: 1.5;

WPDB for post count on post

$post_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_author = '" . $curauth->ID . "' AND post_type = 'campaigns' AND post_status = 'publish'");
?> | The problem you are having is that get_queried_object returns results based on the query that was run.
On author.php, the queried object was an author.
On single.php, page.php, or any custom post type template, the queried object will be the post, not the author.
This means that if you want to use `$wp_query->get_queried_object();`, you will have to be aware of what kind of object you re grabbing ... and possibly do other things if your object is a post or a page.
e.g.
$post = $wp_query->get_queried_object();
$author_id = $post->post_author;
$post_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_author = '" . $author_id . "' AND post_type = 'campaigns' AND post_status = 'publish'");

Is there a way to make a pure vanila page of just HTML/CSS/JS
Bit of a odd question. I want to be able to host example simple websites on my Wordpress Site. These "simple" sites would just consist of client side code.
Is there a way to create a page which just uses these files, possible a plugin I am unaware of?
Thank you. | I've done this in the past by using custom page templates.
Basically, there are two ways to create a custom page template.
1. You can create a file in your themes directory and name it `page-vanilla-html.php`.
2. You can create a file and name it whatever you want (for example `vanilla-html.php`). You just need to include a template description at the top of the file:
<?php
/*
* Template Name: A Vanilla HTML/CSS/JS Custom Page Template
* Description: This template is nothing but vanilla HTML/CSS/JS!
*/
?>
Once you've created the custom template, you simply create a new page within Wordpress. If the name of the page is "Vanilla HTML" it will search for a file named `page-vanilla-html.php` and load it automatically. If you used the second method, you can select the template from the drop down on the right side of the page creation screen. | stackexchange-wordpress | {

Trying to disable slider for WooCommerce price filter
I'm currently working on an e-commerce site that uses WooCommerce, and the client wants to change the price filter from the existing range slider to the two inputs. By default, WooCommerce creates it as two inputs, then uses jQuery UI to replace it with a slider to make it accessible.
Now, I can do this by commenting out the appropriate `wp_enqueue_script` call in WooCommerce itself, but this will obviously get overwritten when WooCommerce gets updated.
As far as I can tell, the following should work when inserted into the `functions.php` for the theme:
function remove_slider() {
wp_dequeue_script( 'wc-price-slider' );
}
add_filter( 'wp_enqueue_scripts', 'remove_slider' );
This is consistent with what I've seen in quite a few blog posts that turned up in a Google search. However, it's just not working. Any idea what I need to do to achieve this? | This script is localized and registered, so you're going to need to use wp_deregister_script() instead of wp_dequeue_script().

Removing backstretch image from pages/posts

Does WordPress count as a means to learn web development?
I'm learning to make themes in WordPress, basically with CSS only. I don't feel like I'm learning actual web development (front end). I don't see how I can incorporate JS into themes, because it seems that WordPress does all the stuff for you (such as the drop-down navigation menus).
I know this is a badly written question. Basically, can WordPress be used as a means to learn overall front end development, or should I try it some other way? | Yes and no.
WordPress is inherently web content management system. Whatever you do with it _is_ web development since end result is, well, a web site.
However not all of WordPress is web development. Not all of web development is something that you typically do in WordPress.
As you grasped WP is strong at back–end and contains immense amount of functionality, as well as means to produce a lot of markup server-side. This is _good_ since it saves you from all that work.
But the other side of the coin is that WP is kind of set in its ways. It is a legacy framework and “newer” (or even years old really) techniques (such as dedicated template languages, JS frameworks, and so on) are often under–explored in it.
In a nutshell starting with WordPress development _does_ expose you to considerable amount of generic web development concepts (depending on what exactly you do with it), but it won't be exhaustive and at some point you will have to look beyond WP to make further progress. | stackexchange-wordpress | {

Must filter functions receive all arguments passed to them?
I'm writing a filter function to redirect logins:
function my_filter_func( $redirect_to, $requested_redirect_to, $user) {
// My code.
}
add_filter( 'login_redirect', 'my_filter_func', 10, 3 );
The filter hook in the template file is:
$redirect_to = apply_filters( 'login_redirect', $redirect_to, $requested_redirect_to, $user );
As you can see, `$redirect_to`, `$requested_redirect_to`, `$user` are passed to my filter function. My filter function receives these and I can use them in my function's code.
**My question:**
Must my function receive all 3 variables? Or can I do this:
function my_filter_func( $redirect_to ) {
// My code.
}
add_filter( 'login_redirect', 'my_filter_func' ); | Your function does not have to accept all arguments, you can not specify the number of accepted arguments and it will default to passing just the first.
You can also specify any number up to and including the total number of arguments. For example if you only need the first 2, this will also work:
function my_filter_func( $redirect_to, $requested_redirect_to ) {
// My code.
}
add_filter( 'login_redirect', 'my_filter_func', 10, 2 );
What you can't do is use more arguments than what you specify in your `add_filter` call. For example, this will generate a missing argument 2 warning:
function my_filter_func( $redirect_to, $requested_redirect_to ) {
// My code.

How to Prove Ownership of plugin
So I'm considering writing wordpress plugins to sell. Apparently distributing these type of plugins requires you to hand over the source code to the client. What would happen if one of the clients claims ownership of my plugins and starts selling them. How would I prove ownership of my plugin?
For example in VB.Net project your code will be compiled so the end user will not have access to the source. So you can prove ownership by showing your code to the court, while he does not have access to it. | You don’t sell the code, you sell support and automatic updates. If your plugin is successful, some people might try to claim the ownership … that doesn’t really matter, they will never be relevant for your business.

Theme options are they necessary
So I have decided to use wordpress for a site. But just as I begun I realized that I might need options. Things as simple as logo, favicon and possibly some parallax settings.
Is it necessary to have options or can I set the logo by just getting the uploads/images path and setting it to logo.jpg.
Then for say the parallax just categorizing pages and based on category use a specific section.php file to perform whats necessary?
I am new to creating themes in wordpress so if its not necessary I would prefer to not use options unless its easier than it looks. So far I got the 'Options Framework' plugin but am not sure how to use it exactly. | If you are developing the theme for yourself to use I don't see any reason for adding options if you don't want to/know how. If you are planning on distributing/selling your theme though, you might want to consider adding some options for your customers to change the settings and customize the theme.
I'd say that options are nice to have, but not necessary at all. If you are new to WordPress, learn how it works first. Then add options down the road if you feel that it would add some value for your site. | stackexchange-wordpress | {

'is_author()' logic in widget for author only
So, I have a widget that I only want to show it to the page author.
I used the following logic: is_author()
However it does not seem to work (it shows non-author)
Am I using this logic right?
Any suggestions?
Thank you | is_author() is only for Archive pages. Quote from the Codex:
> is_author() checks if an Author archive page is being displayed
So viewing a single Post or Page isn't going to get a TRUE from is_author().
I think you'll want something more like this:
global $post,$current_user; // get the global variables to check
get_currentuserinfo(); // get current user info
// Now check if the author of this post is the same as the current logged in user
if ($post->post_author == $current_user->ID) {
// do code here
}
I hope this helps. :)

Post formats and template hierarchy

Is it possible to edit the template hierarchy so that you can append formats to the single template (single-image.php, for example)? Alternatively, if this is best avoided, can anyone suggest another workaround? | It is easy to make this work if your theme don't support post formats
* Create a child theme
* `add_theme_support` for post formats
* Remove the loop from your template files and add replace it with `get_template_part( 'content', get_post_format() );`. Your template should look like this
if ( have_posts() ) { // <- Not necessary in single.php
while ( have_posts() ) {
the_post();
get_template_part( 'content', get_post_format() );
}
}
* Everything else should go into a new file which should be called `content.php`
* Create a new file called `content-image.php` and add the loop in there and modify as needed
* When a post is assigned the `image` post format, `content-image.php` will be used inside single.php to display the image posts

Can't add any menu items anymore, server related
_Unsure if this fits here, but hopefully it does._
So I'm having an issue that I can't add any menu items to a custom menu anymore. At this very point I can verify that it's server related, since this issue is appearing now on multiple Wordpress installations, even a complete fresh one.
For the record: I have tested it, as said, on a fresh installation with the basic theme, newly downloaded Wordpress, no configuration changes, etc.
Each installation on the server has it's own wp-config, .htaccess and php.ini file and there are non in the root (`public_html/`), so neither of those can't be the issue.

How do I include drag-and-drop in a plugin?

I want them to be able to do this with drag-and-drop, just like they add widgets to a sidebar. That is to say, the plugin will have a group of allowable fields, and the users will drag and drop those fields into a box to allow them to configure the fields in a custom post type.
Are there WordPress functions that allow developers to do this? Is there a tutorial anywhere that shows how to do this?
Thanks! | WordPress has a few of these libraries that come with core, you can view the list here: Default Scripts Included and Registered by WordPress. What you're looking for is Draggable, Sortable, and in your case Droppable.
You would use `wp_enqueue_script()` to add it like so:
`wp_enqueue_script( 'jquery-ui-droppable' );`
WordPress registers these scripts using a Handle which you can use to add them, the list of Script Handles can be found in the first link above. You would still need to hook into the admin panel and add the script:
function load_custom_wp_admin_style() {
wp_enqueue_script( 'jquery-ui-droppable' );

Front-end CSS Library for plugin
I'm looking for a CSS library that can style elements I display on the client-side (front-end) of a wordpress website. The CSS library needs to be able to work with most of the wordpress themes, which means it just has a list of classes I can use, and doesn't alter the themes' global style (see below for explanation).
The problem with the libraries I've come across is that they alter the global style of a theme. For example they style the body tag with a background color, they edit the fonts and sizes of h1, h2, h3 etc tags. Another part of the problem is _normalize.css_ , it tends to break themes.
So far I've tried:
* Bootstrap
* Bootflat
* Foundation
* Pure-io (too few styling options)
* Topcoat
In short: I'm looking for a CSS library which doesn't alter any elements unless I attach a class to those elements. This way I can build a plugin which doesn't break theme styles.
Are there any recommendations? | Achieving unaltered style via plugin for multiple themes is pretty difficult to achieve.
How about this?
Use any library among these e.g. Bootstrap in your plugin and then remove/comment the global properties from them.

How to use `wp_insert_post()` and `get_permalink()` functions?

Advantages/Disadvantages Using Theme Editor Instead of Pages
I'm working on a site and I prefer to create the site using the WordPress pages system. A co-collaborator assisting me with the site prefers to add pages using Theme Editor.
My first thought what is the advantage in doing this instead adding a new page via the dashboard?
Are there any disadvantages in creating pages using the theme editor?
If I wanted to use a plugin would the theme editor be able to use that plugin? Or does it isolate itself some how?
If anyone can shed some light on this that would be greatly appreciated. | You should understand that the theme editor is used to change the code structure of the pages something that cannot be achieved by simply creating a page via dashboard.
These are two very different things, while you can add html on your page using the page editor you cannot add some Php there. In simple terms theme editor allows you to edit the structure of pages, styling and create new page templates as well.

Should I not use the text editor to add the shortcode? | Shortcodes get replaced when you output the content via `the_content()` function, or apply the filters hooked to `the_content`.

What's the purpose of 'taxonomies' parameter in register_post_type()?
As mentioned in `register_post_type()` Codex page:
> **taxonomies**
> ( _array_) ( _optional_ ) An array of registered taxonomies like `category` or `post_tag` that will be used with this post type. This can be used in lieu of calling `register_taxonomy_for_object_type()` directly. Custom taxonomies still need to be registered with `register_taxonomy()`.
> Default: no taxonomies
In my Custom Post Type (`product`) I'm also assigning two Custom Taxonomies with `register_taxonomy()` apart from the `register_post_type()`, and they are working fine. But there's a parameter in `register_post_type()` called `'taxonomies'` where it's said to mention all the taxonomies in an array, but even without this I'm achieving what it's meant to:
'taxonomies' => array( 'product_categories', 'product_tags' ),
So, I wonder what's the purpose of this? | To be really honest here, that is a useless parameter when used with custom taxonomies, as custom taxonomies are already registed to a custom post type when they are registered. Using the `taxonomies` parameter, you are re-registering a custom taxonomy to the custom post type
As stated by the codex, the `taxonomies` parameter is used to register build in taxonomies to custom post types, as build in taxonomies are registered to the build in post type `post`.
Just to close of, if you register a taxonomy to a post type, set the `taxonomies` parameter and use `register_taxonomy_for_object_type()`, you are doing the same job three times :-) | stackexchange-wordpress | {

Show post date on the page
What is the php code for showing post date on the page?
For example, it is a woocommerce product and here is the php code that I have so far:
does this work?
if ($hide_price !== '0') :
$output .= '<div class="mywoocmmerceprice>';
$output .= $product->get_categories();
//here is where I want to add the date
$output .= '</div>';
endif;
Thank you | `the_date()` is technically the template tag to do it. However it has a somewhat unusual aspect to only output once per date, so if there are multiple posts on page from same date they won't all show it.
`get_the_date()` is one level lower and retrieves (not outputs) a post's date without that bit of logic. | stackexchange-wordpress | {

Shortcodes Keep Wrapping in <p></p>
I've been ripping my hair out for hours and now I'm almost bald! :p Any time I try to insert any shortcode into the visual editor (on its own line), it wraps them in `<p></p>` tags. This happens when I save or switch to the text tab, even after I've manually removed the `<p></p>` tags. Wordpress is basically treating everything as text. It affects both default WP shortcodes and custom ones. Examples:
[gallery] -> <p>[gallery]</p>
[cardimg][/cardimg] -> <p>[cardimg][/cardimg]</p>
[W][/W] -> <p>[W][/W]</p>
I have tried every single solution here and on Google: < I don't know what to do at this point. Absolutely nothing I do changes the results. | Try <
It basically removes any `p`-tags before and after `[` or `]`, before rendering the content.

Single Must Use Plugins Directory for local development

Should I find/replace values in the_content?
I'm creating a plugin specialized for a website. Most of the pages are pretty general (blog posts, contact pages, etc...) but a handful of pages will have custom code (specific SQL) for display statistics.

Stop WordPress from reserving slugs for media items?

Mapping subdomain to point to sudirectory site in WordPress Multisite Network

WP_User_Query orderby meta_val_num

In the specific case of the Cherry parent theme (which is widely used in templates sold on themeforest, templatemonster etc), you cannot make stylesheet changes in reserved files such as main-styles.css (Despite them existing in a child theme).
The solution is to either make style changes in the style.css, or to make a stylesheet with a dependancy on main-styles.css, in order to override any auto-generated styles.
