How can I make WordPress serve homepage to different URL?
I would like to set up a landing page and a homepage for my WordPress website. I am new to WordPress, but I am an experienced web developer.
WordPress will only serve the homepage content if the URL is `example.com`; however, I would like to force it to serve the homepage content to `example.com/home`.
I was planning on setting the “Front Page” to the Landing Page I have created. And then the landing page will link to `example.com/home`. However, for now the `example.com/home` page is blank, and I would like to have it display the “Home Page” content.
Basically, I am trying to find out whether it is possible to make `example.com/home` serve what is supposed to be on the home page. | You could do this by creating a new page called "Home" with the permalink slug of "home" and another page e.g. "Landing" for your landing page. Then go to Settings -> Reading and set the "Front Page" option to your landing page from the dropdown box. You will then be able to link to `mydomain.com/home` from your landing page. | stackexchange-wordpress | {

Plugin Post 2 Posts: How to list most connected posts?
I want to list the most connected posts ordered by quantity. ¿Is it possible? ¿Could anyone help me with that? I explain with an example: let's say I have `Movies` custom post type and an `Actors` custom post type, that are connected with `Posts 2 Posts`. In the Actors archive, I want to **order them by the number of Movies that they have worked on**.
I think it is maybe possible with `each_connected()`, but I don't know how to order the `$wp_query` array by the number of elements in `connected` subarray for every `$post`.
Thanks. | I have done this way:
// Find connected pages (for all posts)
p2p_type( 'actors_movies' )->each_connected( $wp_query );
Now we have a `$connected` property attached to every post on the `$wp_query`, that is an array of posts connected by `actors_movies`.
$actors = array();
while (have_posts()) : the_post();
$movies_acted = count($post->connected);
if($movies_acted > 0) {
$actors[$post->ID] = $movies_acted;
}
endwhile;
arsort($actors);
foreach ($actors as $id => $quantity) {
//Show the actor info
}
Then, I have made an array with the `ID` of the `$post` as the `key`, and the quantity of `$connected` as the `value`, for each. Then I have ordered it by the `value`, and I have done a `foreach` through the array, to get the post from every `ID`, starting from the most prolific =D | stackexchange-wordpress | {

Include files in functions.php
This is a rewritten post since the way I worded my old post totally confused everyone.
MikeSchinkel shows how he uses Include files in his theme's functions.php file In this Stackexchange post: Organizing Code in your WordPress Theme's functions.php File?
Example:
require_once('includes/my-file.php');
How would you write this php line if the file to include is inside a directory, inside the wp-content directory? Location: [wordpress install]/wp-content/new-directory/my-file.php
The only way I can think of is like this:
require_once( ABSPATH . '/wp-content/new-directory/my-file.php' );
Would this be the correct way? | Including a file inside a subdirectory is the same as any other as long as you know the path to the file. Since it's possible to move the 'wp-content' directory, don't pass that part of the path to the `require` statement; instead, use the `WP_CONTENT_DIR` constant.
require_once WP_CONTENT_DIR . '/new-directory/my-file.php';
Also, you can leave out the parentheses since `include` and `require` are statements, not functions. | stackexchange-wordpress | {

Hook that get's triggered when the author of a post is changed
Is there any hook that gets trigged when the author of a post is modified from the edit post screen?
I can list to the update post hook, but then I will not know whether the author of the post was changed or not. | There is no special hook to author change.
But you can achieve it by using `post_updated` hook.
Example:
add_action('post_updated', 'prefix_on_update_author', 10, 3);
function prefix_on_update_author($post_ID, $post_after, $post_before)
{
if ($post_after->post_author != $post_before->post_author) {
// author has been changed

Targeting specific pages in the loop
I am having a custom query that calls in pages in an array like so:
<?php
$args = array(
'post__in' => array( 2, 7, 9, 11, 13 , 15, 17 ),
'post_type' => 'page',
'orderby' => 'menu_order',
'order' => 'ASC'
);
$the_query = new WP_Query( $args );
while ( $the_query->have_posts() ) : $the_query->the_post();
?>
Is it still possible to target single pages of the array to have page specific alterations of the code, i.e.
<?php if(is_page(7)) { ?>
// do something
<?php } else { ?>
// do something else
<?php } ?>
inside this query or do I have to query every page in a a separate query?
I am using this query to put together multiple pages into one template (front-page.php) in order to have a onepaged layout, i.e. all content on one page, so I would like to use conditions inside the loop for clarity in my code. | You would rather want to use the post ID inside the loop to target your pages. `is_page()` simply checks whether the current page is actually a page or a specific page if a value is passed
## Example
if ( $post->ID === 7 ) {
// Do something for page id 7
} else {
// Do something for other pages

Why not to include reference to /wp-admin/admin.php in Plugin
Contact Form 7 recently pushed out an update which caused a few conflicts in other plugins. WPCF7 Author explains that it's because plugins are including calls to `wp-admin/admin.php` in their scripts which you shouldn't do in a plugin. Takayuki Miyoshi explains it here but I'm not sure I understand exactly _why_ it would cause any kind of issue or how this is different from calling say `wp-load.php`.
Could somebody explain why it's advised never to load `wp-admin/admin.php` in your plugin and how it could cause issues? | > Could somebody explain why it's advised never to load wp-admin/admin.php in your plugin and how it could cause issues?
Because it is loading WordPress out of context-- well, parts of WordPress. And that can cause unexpected effects such as functions not being loaded or functions being loaded twice (which will cause fatal errors). You will have trouble with hooks firing multiple times, or not firing. You may have trouble with constants. You may not have trouble, but that depends upon how and why the files are loaded.
> ...how this is different from calling say `wp-load.php`[?]
`wp-load.php` is a bootstrap file that `admin.php` will load about line thirty-something. It is a similar hack and can have similar problems. It should not be done either.
There is very little reason to use either technique. WordPress should be loaded for you plugin for most purposes and if not, say you need to make a separate request, use the AJAX API which will boot WordPress properly. | stackexchange-wordpress | {

How to disable user registration for the default subscriber user role?
I'm dealing with fake user registrations on my site. Since i'm using WooCommerce, i have a custom signup page which will generate users with **"customer"** as the user role. However, all of the fake users are registering through wp-login.php, which will generate a user with the **"subscriber"** role.
Is it possible to somehow disable the user generation process(probably inside `wp_insert_user()`) if it tries to signup a user with the role set to subscriber? The closest action i could find is `user_register`, which triggers immediately after the user has been created, so i could delete the user if the role is subscriber, but i would like to do this before the user is even created.
Also most of the user data is filtered, but not the user role:( | There might be more elegant way to do it, but from quick look at the code it seems quite easy to simply override the relevant option on login page:

get_posts - require all categories

Shold I manually add 'cap' to admin role ?
I've created a role:
$role = add_role( 'role', 'role', array('read' => true) );
and so created a cap:
$role->add_cap( 'cap' );
after this I'd created a submenu in admin menu with 'cap' as capability argument. So the problem is that the user with 'role' role can see the submenu but the site admin can't see the submenu, so the question is: I have to add 'cap' to admin role ? isn't it automatically ? | A new capability has to be explicitly added to either a role or a user. In your case if you want all administrators to have 'cap' capability you will add it to 'administrator' role:
$role = get_role( 'administrator' );
$role->add_cap( 'cap' );
If you want a specific administrator only to have 'cap' capability then you add it to this particular user:
$user = new WP_User( $user_id ); // $user_id = id of your administrator user

How to search map address in custom post type?

Quotes in table name
Since WP3.5, `prepare()` accepts placeholders as a security measure, instead of just appending the argument to the query. Therefore, `$wpdb->prefix` needs to become a second parameter, called by `%s`:
$count = $wpdb->get_var( $wpdb->prepare( "SELECT COUNT(id) FROM %s WHERE answer !=' '", $wpdb->prefix . "faq_questions" ) );
However, doing that returns the table name in quotes:
`SELECT COUNT(id) FROM 'wp_faq_questions' WHERE answer !=' '`
How can I fix this? | > How can I fix this?
You can't, but it isn't broken. You are telling `prepare` to use a string. A string will be quoted. It isn't meant to generate MySQL syntax, which is what you are asking it to do. Your tablename is more a MySQL command or keyword than a string value. That isn't what `prepare` is for.
`prepare` is meant to operate on user supplied data. Your tablename is not-- well, shouldn't be-- user supplied data so you don't need to "prepare" it. It is unnecessary. Just construct the tablename in the SQL itself:
"SELECT COUNT(id) FROM ".$wpdb->prefix."faq_questions WHERE answer !=' '"

What is the meta-box-order_post_hash used for?
`meta-box-order_post_hash` is stored as an user option. I am sure it's related to `meta-box-order_post` but I could not find anything in the codex about it. So what is it for? And how can or should be used? | I could only find the following core code references for the `meta-box-order_` string:
/wp-admin/includes/ajax-actions.php:
update_user_option($user->ID, "meta-box-order_$page", $order, true);
and
/wp-admin/includes/template.php:
... get_user_option( "meta-box-order_$page" ) ...
that's related to the ordering of meta-boxes.
I doubt your `$page` value is `post_hash`, so my first guess is that this comes from a plugin/theme? If not then the user option might be dynamically constructed.
Searching the wide world web gave be only this plugin on GitHub, that uses the `meta-box-order_post_hash` user meta key.

Custom page pagination based on Kriesi pagination
I am stuck on this problem:
We have 2 custom post types on our website, both created the same way, only the name of the post type differs. In addition we have 2 custom page templates which show an archive of these custom post types.
Both use the same logic / look and feel only the custom post type posts shown differ.
Our problem is that we use custom pagination based on kriesi.at code. However for 1 custom page it works perfectly for the other one it isn't.
We did a diff of all code and cannot find the difference. And biggest problem is that we have absolutely no clue how to debug this since the only difference is the custom post type value...
Anyone suggestions on how to start debugging this? | when writing this question we suddenly thought that we did not try to change the permalink. After changing the permalink to another unique value it worked like a charm.
So still not sure what was causing this issue but the above solved the issue.
If anyone has a clue why the permalink was causing the problem please let us know, might help us by understanding the exact cause of the problem. | stackexchange-wordpress | {

Page and Posts loading as index page? Not loading the content
I've been developing a website on wordpress for some time now and came across some issues but until now I could figure it out, not today... Yesterday I've worked some more on the website and today when I came back to do some more work the pages on my site that are part of my navigation menu didn't load properly (minus the home page that is static and a news page that is the index page), they were loading the index.php page. Also with my posts in the news(index) page the load the index page instead of the post content. The URLs appear correct, but the loaded page is the index one. This doesn´t happen with the other pages I have that are not in the navigation menu and also with some custom post types, everything works fine there.

How to make my third multisite blog start with id 1000?

Theme does not respect spaces between paragraphs in pages
I am working with a theme that focuses on special types of posts. It seems that the author has neglected pages and as a result, paragraph spacing in pages is not respected. The next paragraph simply appears on the next line instead of leaving a line of space between paragraphs. This does not affect special posts, but it does affect pages.
What is the best way to fix that? | The theme's style sheet uses the reset method to set all margins on the `<p>` tag (and many others) to 0 (this is common practice). So you would need to add a style declaration into your style sheet to add the top and bottom margin back in for the `<p>` tag.
For example: you could add this to your style sheet after the reset.
p {
margin: 10px 0;
}
This will add a top and bottom margin of 10px. You can change this to whatever value you like.
You could also set the margins individually.
p {
margin-top: 10px;
margin-right: 0;
margin-bottom: 10px;
margin-left: 0;
}
.added p {
margin: 0;

Generating a certain sized thumbnail on the fly?

Widget logic conditional widget

if ( $post->post_type == 'my_post_type' // checks the post type of the post
&& is_single() // Checks if this is a single post
&& has_term( 'term-name or id or slug', 'my_taxonomy', $post->ID ) // Check if post has specific term

How can I fix the sort without changing the meta_value field type? | First of all, never ever use `query_posts`. It breaks the main function and all plugins and functions relying on the main query object. For custom queries, use `WP_Query` or `get_posts` if aren't looking to paginate the query
As for the following line
'orderby' => 'rr_recommends_count',
I can tell you that `rr_recommends_count` is an invalid value to the `orderby` parameter. Suspect that this is actually the key name, and the values are all numerical in that key, so you would use the `meta_value_num` value to the `orderby` parameter which is a valid value

Get all registered wp theme customizer sections?

I can remove all the default sections, but I can't predict which plugins or themes will register sections.

Is there any other way to retreive registered sections? | After digging around inside of some core files, I was actually able to get this resolved.
The following function will retrieve all registered sections in the customizer and loop over each to un-register them altogether.
This should run before registering any of your own custom sections, as to not remove your custom registered sections.
function eherman_remove_registered_customizer_sections() {
// retrieve the sections array
$registered_sections = $wp_customize->sections();
// loop over and remove each section
foreach( $registered_sections as $section ) {
$wp_customize->remove_section( $section->id );
}
}

in `functions.php` but it is adding the string in the header across the site. How can this be narrowed down to be only included in post pages? | Check the type of the queried object on the page and the post type:
function function_that_returns_js_string() {

echo 'your string';
}

However, I am concerned that you are inserting a script directly into the head of the page rather than enqueueing it, which is more standard practice. The same trick will work to conditionally enqueue:

Display News Posts by Day with Post Counter
I am building a site client who makes anywhere from 20-50 news posts per day. I'd like to have a news feed where it shows the date / post count as an H3 and then list all the posts for that day underneath.
Example...
**TODAY (4 posts)** \- News Article Link \- News Article Link \- News Article Link \- News Article Link
**YESTERDAY (6 posts)** \- News Article Link \- News Article Link \- News Article Link \- News Article Link \- News Article Link \- News Article Link
**MONDAY, JUNE 22, 2015 (3 posts)** \- News Article Link \- News Article Link \- News Article Link

How to add multiple custom URL variables?
I am building a Wordpress plugin that looks for different custom variables in the URL.
The way I am able to achieve that right now is with this code:
function add_custom_query_var( $vars){
$vars[] = "variable1";
return $vars;
}
function add_custom_query_var1( $vars1){
$vars1[] = "variable2";
return $vars1;
}
add_filter( 'query_vars', 'add_custom_query_var' );
add_filter( 'query_vars1', 'add_custom_query_var1' );
I feel like this code is redundant and was wondering if there is a better way to do this.
Thanks | I pretty sure this filter lets you add an array of variables. I've not tested this:
function add_custom_query_vars( $vars ){
$vars[] = "variable1";
$vars[] = "variable2";
$vars[] = "variable3";
//... etc
return $vars;
}
add_filter( 'query_vars', 'add_custom_query_vars' );
Or another way of doing it would be to do this:
function add_custom_query_vars( $vars ){
array_push($vars, "variable1", "variable2", "variable3");
return $vars;

Which Wordpress version to use for improved plugin compatibility?
I am currently using WordPress 4.2.2 and Woocommerce 2.3.11 -
I find that many plugins associated with Woocommerce have not yet been updated for whatever reason. In some cases a whole year has gone by with no updates to the plugins.
* Would it be advisable to regress to an older version of Wordpress?
* Is there a recommendable version to go back to? Say WordPress 4.0/4.1/4.2?
I understand that it may depend on my current situation. Most of the plugins i need to use are compatible to v4.1.5 only.
* Is it advisable(a good/safe idea) to use WordPress 4.0/4.1?
I am concerned about the security problems(if any) if i use and older version. | It is not advisable to run anything but the latest wordpress, especially with regards to security fixes. For a minior wordpress release, you can read the release notes and see if any of the changes are security related. If they aren't, then you can probably safely wait until the next security fix.
In my experience, wordpress updates only sometimes break a plugin. The problem, though, is that if there is a security fix in an update, it is quite irresponsible to not apply the update, especially if you have sensitive data in your system. This is just the burden of modern software, updates are mostly required, but the ofter cause incompatibilities.
A good solution is to set up a staging environment for yourself to see if the update breaks any plugins. If it doesn't, apply the update, if it does, start working on a contingency plan.

`get_theme_file_path()` (for absolute file paths) and `get_theme_file_uri()` (for URLs) work just like `get_template_part()` in that they will automatically look in the child theme for that file first, then fallback to the parent theme.

Getting Category Children
i have a problem understanding the get_terms function
All i want is getting all the children of specific category so that it can be listed. But i don't really know how the $args works.
So with this `get_terms(category, $args);`
I tried to use the child_of
$args = array(
'child_of' => 0,
'childless' => false,
);
But it gives all the category while i only need the child of a category. Changing the value to "1" gives empty result.
Then i tried the 'slug'
$args = array(
'slug' => 'on-going',
'child_of' => 0,
'childless' => false,
); `
This gives nothing but "On-going" only.
This is the category tree in my wordpress
!category
The only thing i want is listing all child category of "On-going", that's it....
Thanks | The `child_of` parameter excepts an integer value of the specific term you need to get descendants from. This means that you need to get the ID from the `On-going` category term and then passing that ID to the `child_of` parameter.
To note, the `child_of` parameter returns **all** descendants of the term passed, this includes direct children and all children of those children etc. If you only need first level children of a specific term, then you need to pass the term id to the parameter `parent`.
If you do not have the exact id, you can use `get_term_by` to get the id and then pass that to `child_of` in `get_terms`
## EXAMPLE
This example shows how to get the term ID if you only have the term name, like in your case `On-going`
$get_term_id = get_term_by( 'name', 'On-going', 'category' );
$terms = get_terms( 'category', array( 'child_of' => $get_term_id->term_id ) );

JQuery UI not loading without explicit loading of jQuery
I know there are a lot of questions regarding this issue, but I can't figure out mine here. I'm trying to load the whole jQuery UI ( Actually I need only the Slider ) and I successed. This is my enqueing which is working:

Why I cannot use them and load them twice? When I remove the jquery enqueueing, jquery UI is not loading. Is it a good practice to load jquery from external sources? Why the wordpress jquery is in version 1.4.1 and google's 2.1.4? When there are these libraries loaded, why can't I use them in the front end? I got quite confused about this. | jQuery and the jQuery UI Slider are both registered by default by WordPress. In order to use them, all you should need to do is something like this:

function wpse192997_load_slider() {
wp_enqueue_script( 'jquery' );
wp_enqueue_script( 'jquery-ui-slider' );
}

**2\. Add A Filter**
Move the above code into your theme's `functions.php` file and wrap it in a function. Then add a filter to `the_content()` to make it include your new function. Your code should look something like this:
function my_the_content_filter(){

How to change user password with wp-cli?
wp-cli is great. But it's not clear how I can quickly change a user password with it.
How to change a user's password programatically can probably help to figure this out.
Although `wp user update username --field=password` is not gonna cut it, apparently `md5` is deprecated so it should go through `wp_set_password`. | This does the trick:

Wordpress get_posts by category
I have the following bit of code:
$args = array(
'posts_per_page' => -1,
'category' => 7,
'orderby' => 'name',
'order' => 'ASC',
'post_type' => 'product'
);
$posts = get_posts($args);var_dump($posts);
This should return one post I know that is in the category, but it isn't. If I leave out the 'category'-argument, I get all the products, so I know this should normally work. If I change the category to 1 and take out my custom post type (product), I get my default posts.
I can't see what's wrong with this. Can anyone spot what the problem is? | In all probability you are using a custom taxonomy, and not the build-in `category` taxonomy. If this is the case, then the category parameters won't work. You will need a `tax_query` to query posts from a specific term.

Register Page Template from Plugin
I'm trying to figure out how to properly register a page template (and all of the associated assets, like CSS and Images) from a plugin. Basically, I've created a landing page that I want to live outside of the Theme, so I can use it on multiple websites.

function custom_page_template( $page_template )
{
$page_template = dirname( __FILE__ ) . '/custom-page-template.php';
return $page_template;

But I'm not seeing the page template within WordPress. | You misunderstand what `page_template` does. It does not create a new template that you will "show up" somewhere and that you can use. It replaces the `page.php` template provided by the theme.

if (is_home()) {
get_header();
echo 'do stuff';
get_footer();
}
}
add_filter( 'template_redirect', 'custom_page_template' );

How to add a class to figure tag for featured images?

NextGEN Gallery - set lightbox image size
I use NextGEN gallery with lightbox effect. Is there any way how to set the lightboxed image to f. ex. to max width: 600px? Without resizing the source image? I have tried all of possible Lightbox Effect setting, but nothing has helped.
We use big pictures (+3000px width) because our users can download them through NextGEN Download Gallery so we don't want to resize them. But if you click on image as a lightbox is loaded the big image which is really useless and pretty big so it takes time and data traffic.

* nextgen-problem-resize-images-automatically-in-screen-resolution-function

2. or use backup files created by NextGenGALLERY by changing the source code of plugin - see here

Question on using custom structures for categories
Im trying to create a topics "section" similar to what Justin Tadlock has on his site but i'm not sure **how** he is doing this. Categories? Tags? or what?
I tried changing the Category base to topics as the instructions state:
> If you like, you may enter custom structures for your category and tag URLs here. For example, using topics as your category base would make your category links like <
Now assuming my category is "foo", when I visit ` I see the proper listing of articles categorized as "foo".
But when I back out to ` i get ...nothing. Whereas I assumed I would get a list of all categories.
Again looking at Justin Tadlock's site, it appears each item in his "Topics Archive" is actually a tag?
How is this done?
Is he using a Custom taxonomy or what? How do I approach this?
Please advise.
\--pkd | The simple and quickest solution is showing categories list by using sitemap plugin with short-code.

Why does wp_enqueue_style() in plugin not load stylesheet?
I'm trying to load a custom stylesheet (for the front-end, not admin area) via plugin. As near as I can tell, I'm doing things the way the Codex says is correct, but my CSS doesn't get loaded. This is what I have:
/*
* Load stylesheets, etc.
*/
function cl_chanimal_scripts() {
//Register CSS
wp_register_style('cl-chanimal-styles', plugins_url('css/cl-chanimal-styles.css', __FILE__));
//Use it!
wp_enqueue_style ( 'cl-chanimal-styles' );
}
add_action( 'wp_enqueue_scripts', 'cl_chanimal_scripts' );
Am I using the wrong action hook? It is possible to load front-end styles via plugin, is it not? | First thing to mention is that you don't need to use `wp_register_style` if enqueuing within the same function. You can replace it with `wp_enqueue_style` and remove the duplicate.
As for why your stylesheet isn't loading, start by checking the file path. Try this instead:
`wp_enqueue_style('cl-chanimal-styles', plugin_dir_url( __FILE__ ) . 'css/cl-chanimal-styles.css' );`

Include Class File in Wordpress
I'm including a Class file in `functions.php` file
require_once get_template_directory() . "/core/classes/General.php";
require_once get_template_directory() . "/core/classes/User.php";
When I do `$user->getCredits($user_id);` in some page, it works fine. But when I tried doing that same line of code in `header.php` it prompts an error of `Call to a member function getCredits() on null`.
So what I did is I required the same file in `header.php`, it still gives the same error, when I removed the included file in `functions.php` the error was removed and the code in header.php works (`$user->getCredits($user_id)`) but then in normal pages it does not detect the required file.
Any solution for this stuff? | Please clarify where you initiate the object $user in both ways (function.php and header.php).

Ignore/Skip default value on orderby menu_order?
Is there a way to query all pages and order them by `menu_order` **but** ignore those pages that the default value of `0`?
I was trying to do something like this:
$the_query = array(
'post_type' => self::POST_TYPE,
'posts_per_page' => $total,
'product_cat' => $product_category_name,
'orderby' => $orderby,
'suppress_filters' => '0'
);
Or do I need to create a filter to alter the `WP_Query`? any ideas?
cheers | You can try the following ~~(untested)~~ mini plugin:
<?php
/**
* Plugin Name: Support for ignoring the default menu order in WP_Query
* Description: Uses the _ignore_default_menu_order argument
* Plugin URI:
*/
add_filter( 'posts_where', function( $where, $q )
{

if( (bool) $q->get( '_ignore_default_menu_order' ) ) {
$where .= "AND {$wpdb->posts}.menu_order <> 0";
}
return $where;
}, 10, 2 );
Then you should be able to use the new custom query argument like:
$query = new WP_Query(
[
'_ignore_default_menu_order' => true,
]
);
to ignore posts with the default menu order (`0`).

Set post tags using tag ID
I want to set post tags to a new value. Is there a way to use the **tag ID** to do it? The `wp_set_post_tags` only accepts the **tag name** or an **array of tag names**.
<?php wp_set_post_tags( $post_ID, $tags, $append ) ?>
The reason why I want to set the tag using the `ID` is I don't want to make an additional call for getting the full tag object. | For non-hierarchical terms (such as tags), you can pass either the term name or id. If you pass the id there is only one caveat: You must pass it as an integer, and it must be in an array. This is necessary because any non-array value passed will be converted to a string, which will be interpreted as a term name.
$tag = '5'; // Wrong. This will add the tag with the *name* '5'.
$tag = 5; // Wrong. This will also add the tag with the name '5'.
$tag = array( '5' ); // Wrong. Again, this will be interpreted as a term name rather than an id.
$tag = array( 5 ); // Correct. This will add the tag with the id 5.

Should non-WordPress data get its own DB?
I couldn't find anything on Google or on here about best practice for data that is not really Wordpress related.
Say we have a database of clients that we'll be accessing through PHP/SQL. Should I just create new tables within the wordpress database or is it good practice to keep these in completely separate databases?
Currently its very basic and was actually being done as an external CSV.

Rewritten URL not loading WordPress environment
I have a page that I am sending users directly to so I can serve them a PDF dynamically created using the FPDF library. Since I'm sending them directly to the file which generates the PDF, I'm rewriting the URL. In the original file I use `require_once('wp-load.php')` with the correct path in order to load the WordPress environment. It loads perfectly fine and spits out the PDF when I go to `website/path/to/file.php?p=foo&q=bar` but when I go to `website/rewritten?p=foo&q=bar` the `require_once()` function is breaking.
I can tell that my rewrite rule is working properly because when I add debug messages to the file, they are printed when I go to `website/rewritten?p=foo&q=bar` and using `dirname(__FILE__)` returns the path of the actual file not the template.
