Change plugin's has_archive = true to false?
When a plugin registers a post type and sets `has_archive` to `true`, is there a way to change it to be false? I don't want the plugin's post type to have an archive, but can't figure out how to turn it off.
A similar questions was asked here, but has no responses: Changing a custom post type "has_archive" after registered | The `register_post_type_args` filter (available from WordPress v4.4 on) will allow post type registration arguments to be changed:

Updating user meta
I'm struggling to figure out to get the code to update a single current user meta. For instance if I want to update their first name automatically. I'm using
$current_user = wp_get_current_user();
to call the current user data rather than specifying a particular user ID. | One of two functions you'll need; `update_user_meta` or `add_user_meta` \- more often than not you'll just need the former, but it's worth noting the difference:
> `add_post_meta` will only create an entry if the `$unique` parameter is false, or if there is **no** existing data for `$meta_key`. `update_post_meta` will add if no data exists yet, otherwise it will update, depending on if/what you specified for `$prev_value`.
Both functions take the same three initial parameters; a user ID, a meta key, and a value:
$current_user = wp_get_current_user();
$current_user->ID; // The current user ID
$current_user_id = get_current_user_id(); // Alternative for getting current user ID
// Update current user's first name
update_user_meta( $current_user_id, 'first_name', 'Jimbo' );

How to make mailing queue using php's mail() function

How to display the user's comment status on the front end
How can I display the current status of a user's comment/s (on the front end), that is, "approved" or "pending" | Displaying comment status is quite standard in every theme; maybe you have not been notice it but you have seen it for sure. All default themes do it and the default `wp_list_comments()` function does it also and it is the most common function used to display posts comments.
So, if you use default `wp_list_comments()`, you are displaying comment status already; if you are using a custom callback, you can check the comment status, for example like this:
<?php
if ( '0' == $comment->comment_approved ) {
?>
<p class="comment-awaiting-moderation"><?php _e( 'Your comment is awaiting moderation.' ); ?></p>
<?php
}
Or more accurately, you can use `wp_get_comment_status()` function:
// Return 'deleted', 'approved', 'unapproved', 'spam' or false on failure
$status = wp_get_comment_status( $comment_id ); | stackexchange-wordpress | {

Referencing files in JavaScript in WordPress Plugin
I have a JavaScript file in my plugin in which I need to reference a sound file to play when any link is clicked in any front end page.
I did it like this:

var sound = new Audio('sound.mp3');
$('a').on('click', function(){
sound.play();
});
})(jQuery);
I added the 'sound.mp3' file in the root folder of my plugin like this:
my_plugin/sound.mp3
But the reference of the sound file in the js script is incorrect. How should I refer to the file correctly? | Use `wp_localize_script`.
function pr_add_link_sound () {
//Register the script first
wp_register_script('add_sound', plugins_url( 'add_sound.js', __FILE__ ), array('jquery'), '', true);

Multi domain, multi sites with different themes and content
I have about 300 domains I need to setup wordpress. Then for each of them, I need different theme, and content of the sites will be different as well.

foo.com
bar.com

How to get all featured image sizes and their URLs?

Display 4 chronological posts starting with a random post
I know that I can display 4 random posts by doing something like:
get_posts('orderby=rand&numberposts=4');
What I'm trying to achieve is starting with a random item, but then showing the next 3 posts that are in chronological order.
I'm thinking something along the lines of this:
$posts = get_posts('orderby=rand&numberposts=1');
foreach($posts as $post) {
the_title();
//get next 3 chronological posts and loop
}
I guess I need to use something like the 'offset' parameter, but with a post id instead of a position? | For a random offset we might try:
$ppp = 4;
$total = wp_count_posts()->publish;
$offset = $total < $ppp ? 0 : rand( 0, $total - $ppp );
$posts = get_posts( [
'posts_per_page' => $ppp,
'offset' => $offset
] );
## Example:
Let's take `$ppp` as 4 and assume `$total` is 6.
Then are three possibilities for the `$offset`, namely 0, 1 and 2:
Nr Offset Selections
1 0 x
2 1 x x
3 2 x x x
4 3 x x x
5 4 x x
6 5 x
so
$offset = $total < $ppp ? 0 : rand( 0, $total - $ppp );
would give:

Three variables on conditional tags
I'm trying to return $ad_code if three variables are present, but it doesn't allow the third variable I'm trying to add. I want to exclude a category.

if ( is_single() && ! is_category( '1293' ) && ! is_admin() ) {
return prefix_insert_after_paragraph( $ad_code, 2, $content );
}
return $content;
The code (including the code that specifies what $ad_code is) works. Just when I try to add in `&& ! is_category( '1293' )` it still displays on all posts (not just 1293). I tried using the category name as well, but that also did the same thing.
The third variables I've tried either stop `$ad_code` from loading on all or on no posts. | Your conditional, `is_category()` is wrong here. `is_category()` checks whether or not you are actually on a category page. By using the `!` operator in conjuction with `is_category()` and ID `1293`, this part of the condition will always return true except when you are actually on the category page for category `1293`.
If you need to exclude a certain set of posts from the category `1293`, you should use the conditional check, `in_category()` or `has_category()` ( _in essence, they both are excatly the same_ ). So your conditional statement should look something like this:
if ( is_single() // Make sure we are on a single page
&& ! in_category( '1293' ) // Make sure the post does not belong to category 1293
&& ! is_admin() // Make sure this is not an admin page
) {

Get_template_part seems to be ignoring my template
I am developing a website that requires specific pages to have certain elements change color in addition to a full-width calendar page. I figured that using page templates and changing what `get_template_part` looks for would be the simplest approach, but I've run into unexpected trouble. The page template loads fine, but the specific content template appears to get ignored, with WordPress instead loading the general template. I'm using a child theme derived from Twenty Fifteen, but this shouldn't be a problem, since the customized content template loads just fine.
get_template_part( 'content', 'page', 'kahvilaravintola' );
It should be loading `content-page-kahvilaravintola.php`, located right in the child theme's folder, but instead loads `content-page.php`, located in the same folder. I can't seem to figure out what is wrong. | Taken from the Codex and Dev Hubs:
>
> <?php get_template_part( $slug ); ?>
>
> <?php get_template_part( $slug, $name ); ?>
>
`get_template_part` only takes 2 parameters, not 3. If you look in your error log you should be seeing warnings and notices that you passed a third parameter to a function that only takes 2. I would expect your call to load the file `content-page.php` then `content.php`.

How to identify which javascript is being executed
I am trying to figure out which script is being called and executed within my Wordpress website.
I have website with a number of scripts that are included by the core, the theme and the numerous plugins i have installed.
This is not just for one site but on all sites I manage - I usually install w3 total cache to minify the scripts which works great BUT there are always 1-2 elements on site that stop working if their scripts are minified.
I can turn off minify to make it work again and I can exclude scripts from minification BUT I have no idea which script is listening to the functions that are failing. Removing scripts one by one is really time consuming and with the added "caching" of total cache, I can never properly identify the actual script accurately?

Why BuddyPress fields not saving?
I have a Wordpress+BuddyPress site. I added some extra fields in user profile. When i registering user i fill all fields on register form. After i do redirection in user profile:

wp_set_current_user($user_id);
wp_set_auth_cookie($user_id);

get_currentuserinfo();

exit();
}
add_action( 'user_register', 'auto_login_new_user' );
?>
And see that BuddyPress's fields is empty. Only default wordpress fields filled.
If i not do redirecting (i mean after registretion use a actiovation email to activate user) all fields in user profile are filling.
Any advises? | The `user_register` hook probably fires too early.

How to add and clear custom post types and taxonomies in a plugin? Considerations for existing data
How do we manage the creation/deletion of custom post types and taxonomies in a plugin?
For example, if I write a plugin that creates a new custom post type and an associated custom taxonomy, what is the best practice when this plugin is removed from the system?
I would like to delete/de-register the custom post type and taxonomy and delete all the content.
How should I do this? | Custom post types and taxonomies can be registered using `register_post_type()` and `register_taxonomy()`. These functions do not actually create any data in the database. Data _is_ added when users populate content (posts and taxonomies).
When a plugin is disabled, any post types and taxonomies that it registers will be unregistered, but all of their data in the database will remain in place.
If you are going to remove data from the database, you should make it abundantly clear to the user what is happening. One common pattern is to require the user to click an option that states that they want data to be deleted when _deleting_ the plugin. The data deletion process can be run using the `register_uninstall_hook()` or `uninstall.php` file. Data should not be removed when simply deactivating a plugin. | stackexchange-wordpress | {

query_posts works while get_posts doesn't

Display post_meta-by_key on product catalogue

echo get_post_meta_by_key( 'author' );

Not tested, because I don't have a WooCommerce install handy (and WooCommerce specifics are off-topic here anyway) but this is pretty standard so it should just work for you.

What content to use for inserting images

<div class="col-md-6">
<?php the_content(); ?>
</div>
<div class="col-md-6">
<?php // include images ?>
</div> | Images (and other media) in WordPress are stores as attachments — which are a special native post type (more or less).
There are two common ways to display attachments in a post context:
1. Include them in post content (individually or via gallery shortcode)
2. Select one as featured image (aka post thumbnail) and have theme with support of the feature display it separately from content
So unfortunately natively there isn't a way to select _multiple_ images with intent of displaying them separately from content.
However it is a common feature in custom fields frameworks. They often offer nifty interface options for it and store attachments IDs in post's meta data, from where it can be retrieved and used.

Using URL variables on a custom WP_Query

How can I use this method to filter the 'listen' page, by 'category_name' (show name)?
Thanks, Andy. | WordPress doesn't handle this logic qutomatically so you will have do do it manually.
What you need to do is:
1. Read the url parameter with get_query_var( 'category_name' );
2. injects it in your custom WP_Query:
$custom_query_args = array(
'post_type' => 'post',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'post_format',
'field' => 'slug',
'terms' => array( 'post-format-audio' ),
),
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => get_query_var( 'category_name' ),
)
)
);
Note that if you decide to pass an arbitrary variable instead of category_name, you will need to declare it before using it.

Replacing Images in Media Library
I have a media library containing 500 images. I need to make some modifications to these images in Photoshop (batch resizing and color correction). I'm looking for a way to simply overwrite the files in the 'wp-content/uploads' directory without having to re-upload them via the media library. The file names will stay the same. I also want to be able to retain the title, alt, caption and description associated with the old image files.
What would be the most efficient way of going about this? | Well, I think the easiest way would be the following:
* Download your `wp-content/uploads/` folder so you have all images on your hard disk
* Remove the images WordPress has automatically generated (the ones with -*x*.jpg, maybe read this if you have SSH access as a filename)
* Optimize your base images with Photoshop
* Reupload the images into the `wp-content/uploads/` folder
* Use a plugin like "Regenerate Thumbnails" (I use that one often) to rebuild all the necessary images
This should work, but I have not tested it.
**Important!** Do not change the filenames of your base-images, otherwise WordPress will not find them after reuploading. _(Yeah, seems obvious, mentioned it just for clarification...)_ | stackexchange-wordpress | {

Custom Fields with get_post()
I am using get_post() to call a single Wordpress post using it's post ID. I have successfully managed to pull the content / title of the post but would like to also pull custom fields also.
The code below is how I declare custom fields in a standard wp_query:
$customField = (get_post_meta($post->ID, "_mcf_customField", true));
And my get_post code below:
$my_id = 401491;
$post_id = get_post($my_id);
$customField = get_post_meta($post_id, "_mcf_customField", true); // I do not think this is correct
$content = $post_id ->post_content;
echo $content;
echo $customField; // No output
I believe the customField variable above is declared incorrectly, cannot seem to find anything in the Codex that sheds any light though. Does anyone have experience using Custom fields with get_post? | You already know the ID, so just use it:
$customField = get_post_meta($my_id, "_mcf_customField", true);

problem migrating files from https to http mock site - how to see mock site

Thanks. | Since you cannot get access to the website due to a HTTP/HTTPS conflict, you need to ensures that all of the URLs for your website are up-to-date, try the following steps using the Search Replace DB tool:

Is there a way to get attachment data?
So, I'm no big fan of how WP stores images (image data) and I was hoping there had been made some improvements in version 4.x. But alas no.
When I say image data, I mean `url, title, caption, alt text, description` data that you can update in the media gallery.
`wp_get_attachment_image` only returns a URL with this data
`wp_get_attachment_image_src` only returns url
`get_attached_media( 'image' )` returns some data:
public 'post_content' => string 'This is the description'
public 'post_title' => string 'This is the title'
public 'post_excerpt' => string 'This is the caption'
public 'guid' => string '
After I removed the attachment (and deleted the image), then attached another image, `get_attached_media( 'image' )` returns empty.
So **IS** there any good way of getting image data? | Don't forget that attachments are just _posts_ (though they are native posts and those tend to be a special case).

Dynamically creating content on custom URL without getting 404

mypage.com/item/subitem/code

Stop refresh event in customizer

Right procedure when you develop a WP Website for a client

1. create a database and sub-domain on my server
2. install Wordpress and the relative template
3. start to develop the website
4. When everything is ok for the client export the Website (plus the Database) and import it on client's domain.
Is this procedure "correct"? | This is a suitable method. There are plenty plugins in the WP Plugin Directory that can 'migrate' your site for you including plugins and their settings.

Access general settings trough wordpress files
I was reading an article about HTTPS and that you could turn on SSL and HTTPS for Wordpress quite easily.
However in the article it said that you should go to Settings > General Settings within the admin panel and change Wordpress Address (URL) and Site Address (URL) from http:// to
However after doing this I'm no longer able to access my admin panel as it always wants to go to https. I just get to a page that says "This webpage is not available"
So my question is, would it be possible for my to navigate trough the Wordpress Install files and undo this? | You should be able to amend those items from the database.
In the table `wp_options` there are the option_names `home` and `siteurl` \- editing these back to the `http` version should do the trick.
You might also want to check your `wp-config.php` file for the following:
define('WP_SITEURL', '
define('WP_HOME', '
And remove the 's' here as well.
Turning on HTTPS and SSL for WordPress is very easy and what you have done will work - so long as you have already uploaded and installed a valid SSL certificate onto your server, without this there is no way for the server to actually be certified, and the https website url will not work. | stackexchange-wordpress | {

How can I hide the entire "Shipping Details" block on the admin side of Woocommerce?
My Woocommerce store has virtual products that don't require shipping. I have disabled the shipping options from the customer on checkout, but now I want to hide it on the backend as well.
When viewing orders on the admin side, I have 3 columns: General Details, Billing Details and Shipping Details. I want to remove the Shipping Details in the third column so that later I can add some custom fields there instead.
I've tried using
remove_filter( 'woocommerce_admin_shipping_fields', 'filter_woocommerce_admin_shipping_fields' );
but that doesn't change anything on the backend.
I could probably do it with some deeply complicated CSS and display:none, but I'd rather just remove it programmatically, like with a remove_filter or something. | There is no "clean" solution for what you are asking.

Custom post type and taxonomy cross registration
I intend to set up the following:
* CPT: job, team-member

$args = array(
....
'hierarchical' => false,
'rewrite' => array( 'slug' => 'location' ),

....
'rewrite' => array('slug' => 'careers'),
'taxonomies' => array('location'),

Custom field value not saving when it contains a URL?
I implemented a custom field into one of my post formats called 'url'. When I enter a random string of characters into the field, it saves just fine and I display it in my template like this:
`<h2><a href="<?php echo get_post_meta($post->ID, url, true); ?>"><?php the_title(); ?></a></h2>`
However, whenever I enter a URL into this field, i.e "< the value doesn't save. What is going on here? Am I doing something wrong or do I have to treat URLs differently? | After some testing, I figured out the issue. With the Advanced Custom Fields plugin, you have to make sure your field name is unique in order for it to save properly.

Why is an empty result an error? ( $wpdb->get_row )

But your SQL is wildly complicated for you are doing. That is entirely equivalent to
SELECT * FROM $table ORDER BY id DESC LIMIT 1

Send notification to the admin when new custom post is submitted

$subject = 'Subject';
$headers = 'MIME-Version: 1.0' . "\r\n";

wp_mail( $mailadmin, $subject, $message, $headers );
}

WP_Query for products always returns empty

'taxonomy' => 'product_cat',

'terms' => 280 // You can use an array to include multiples terms i.e. array(280,281)

Modify Image Source With The_Content Filter?
I'm very inexperienced with regex, however I'm trying to create a function that filters through `the_content()` and `get_the_content()` in order to modify the SRC of all images. The intended purpose would be to modify the URL's to use ` instead of ` This would allow posts to utilize the Photon API without needing the JS side of Photon..
I know I need to hook into `the_content()` using a filter in order to accomplish this, but I was unable to accoplish this using `str_replace()`, so I'm assuming using `preg_replace()` would work.
Also, if it's possible to add `?quality=70&strip=all` to the end of the URL this would help decrease page speed.
Any thoughts? | Let's give it a try:
$str = '<img src=" />';
$pattern ='#<img src=" />#';

Creating new menu item

Is there a way to change a post's thumbnail image(s)?
I just recently finished the first version of a blog (here: < ), but whenever I share a post on social media, the thumbnail image is the atrocious scaled up version of one of the social media icon's I have on the footer.

Thank you very much! | Facebook scrapes your pages for images to go along with the post you share. When it finds an image on the page it will use that.
To specify which image exactly you have to use Open Graph tags in the `head` part of you html page. The `og:image` tag in particular:
<meta property="og:image"
content=" />
Here is a list of plugins that insert the Open Graph tags for you. If you like to put the Open Graph-tag code in functions.php yourself, check this article.

How to change text of a widget depend on condition?
I have text widget with default ads on it ( google ads for example ).
Sometime, depend on condition like location, time, I need to change the default ads from code, just temporary only.
Is there anyway to do that? | It should be pretty easy to alter the text for the Core text widget via the `widget_text` filter:
function conditional_text_widget_wpse_207957($text) {

}
return $text;

Can I use namespaces in my plugin?
I am building a plugin that I hope to eventually put on Envato CodeCanyon.
Currently I am creating functions of the form `mypluginname_action`. This is quickly becoming silly as I have to do that a lot. I'm thinking of using PHP namespaces, but I'm worried that there might be a reason why I shouldn't.
1. Are namespaces compatible with WordPress and Envato's coding standards?
2. Can I use namespaces in the PHP versions that I should be supporting?
3. Are there any professional theme/plugin makers who make use of the namespace feature? If not, why not? Are there any common pitfalls with using namespaces?
I am well aware that I can research all of this myself, and of course I will, but as I'm early in development, at this point I'm hoping for a quick answer from more experienced people who might have already looked into this.
I appreciate any thoughts on this. | It's almost four years after I asked this question. For anyone reading this now, namespaces are officially supported. From the 5.2 release notes:
> The minimum supported PHP version is now 5.6.20. As of WordPress 5.2, themes and plugins can safely take advantage of namespaces, anonymous functions, and more! | stackexchange-wordpress | {

Load plugins'.mo and .po files from a directory
What I'm trying to do is simple: I have so much WordPress plugins, and 3/4 of them aren't translated in my language, so I want and can translate them all without problems, but I would insert translations inside a directory, so everytime I update plugins I don't have to re-upload in every plugins folder the translation...
Could this in some way be achieved?
It's like as a **child theme** works; so if you insert for example, _header.php_ in child theme, WordPress will load code from there.
Practically I would create a directory like **wp-content/translations/name-of-plugin/en.mo** ; exists any way to tell WordPress to use that directory to take translations? Thank you! | This is, in fact, already available by default. If specific locale isn't available in plugin's folder WordPress will try to fallback to languages directory.
It is defined by `WP_LANG_DIR` constant and for plugins the default location would be `wp-content/languages/plugins`. Note that name is expected to follow the specific format: `name-locale.mo`. | stackexchange-wordpress | {

Theme RTL semi work but with "?rtl=1" fully work
I have a theme which support RTL. RTL direction semi work with WPML plugin, but when I add `?rtl=1` to URL it work fully. I mean it switch direction in the correct way.
How I can switch direction without add `?rtl=1` to each URL? | Looking at the source, there is no programmatic way to accomplish that. There is only one location where `$_GET['rtl']` is referenced and its value is used directly (i.e., it is not used to set the value of another variable used in the plugin). The function you would want to modify if you want the same effect without passing the `rtl` parameter is `function _show_post_content()` in `inc/translation-management/translation-management.class.php`. Specifically this block of code looks to be the only place affected by the parameter:
[...]
if ( @intval( $_GET[ 'rtl' ] ) ) {
$rtl = ' dir="rtl"';
} else {
$rtl = '';
}
echo '<html' . $rtl . '>';
[...]
You could just remove the if/else statement all together and change the echo to `echo '<html dir="rtl">'` for a quick "hacky" fix if desired. | stackexchange-wordpress | {

Is there a hook before the user is authenticated?
I'm looking for a hook that can be used before WP reads the DB to authenticate the user's login credentials, but can't seem to find one anywhere. Does one exist?
I tried `add_filter/action('authenticate', 'customcode', 30, 3)`, but this seems to execute as soon as the `wp-login.php` page is requested, rather than after the user hits login and the username/password is `POST`. | Ah, turns out `add_filter/action('authenticate', 'customcode', 30, 3)` was what I was looking for...
The problem was, I had the priority too low so whatever response I was creating with my custom code was over-ridden by the other filters.
So dumping `global $wp_filter['authenticate']` I could see the following filters:
20, wp_authenticate_username_password
30, wp_authenticate_cookie
99, wp_authenticate_spam_check
By changing the priority to 100 (or higher), I could do the overriding instead and create the response I wanted for handling the login credentials submitted via the login page. | stackexchange-wordpress | {

You need to login with a user that has edit posts capacity?
I have a network blog and after the user has created a site they are getting an error when trying to save their post:
> You need to login with a user that has edit posts capacity
Shouldn't they have edit posts capacity when they've created their account? | _Short answer:_
Incorrect URL. Was trying to save to the network path and not the user path.
_Long answer:_
I have a network blog. I have an examples blog with the default user. With the default user I made posts. When a new user signs up they get a copy of that post locally on the client side (JSON of the post data). It is a duplicate they can use to get started. When default user saves it works fine because he is at the default network path. When a new user saves it does not work because new user cannot save to default path. New user can only save to new user path.
Default user path:
> <
New user path:
> <
The client side JSON object that was duplicated was trying to save to the original URL (this worked for default user who has same path):
> <
Once I updated the path to new users site:
> <
...he was able to save the document.
The error message was correct. My code was incorrect. However, the error message could have contained more information. | stackexchange-wordpress | {

Run "the loop" in a random order
I'm using a transient to store a query that gets 60 posts and makes a mosaic of background images, because it improves performance greatly.
The query has 'orderby' =>'rand' set, but obviously when it's retrieved from the transient it displays the same each time.
My question is, can I make the loop display the results of the query in a random order? This would then equal my original state with much better performance.
Thank you. | As I understood, you want the same results but randomize their order. So, you need to shuffle that results. That is quite simple using `shuflle()` PHP function. But that function needs arrays, not objects.
You could convert the object from WP_Query to an array or, I think better, use `get_posts()` instead of WP_Query.
$args = array(
// Arguments to get posts
);
$posts = get_transient ( "your-transiente-name" );
if( $posts === false ) {
$posts = get_posts( $args );
set_transient( "your-transiente-name", $posts, "the-expiration-time" );

When you register a sidebar in Wordpress, is it possible to choose in what order it appears in the admin

How can I query on the year part of a complete date in a custom field?
My posts have a custom field named _production_ _date and formatted YYYYMMDD.
How can I form a meta_query to select only the YYYY part?
$meta_query_args = array(
array(
'key' => 'production_date',
'value' => '2004',
'compare' => '???'
)
); | The handy thing about how ACF stores dates as `YYYYMMDD` is you can treat them like integers and get a similar level of functionality as if you were using "true" dates.
For example, to get all dates after 1st Jan 2011, use `> 20110101`. Those before June 1st 2012? `< 20120601`. And for your case, all dates within 2004? `>= 20040101 && <= 20041231`.
Translated into a meta query:
$year = '2004';
$meta_query_args = array(
array(
'key' => 'production_date',
'value' => array( $year . '0101', $year . '1231' ),
'compare' => 'BETWEEN',
'type' => 'NUMERIC',

Change reset password URL returned by wp_lostpassword_url() via plugin

Function to change post status IF current user and post author are the same

Thanks | You won't get anything back from your template simply because the loop returns what is in the main query object for that specific page. To see what is actually in the main query object, you should do `var_dump( $wp_query );` outside the loop.
To display custom content on a page template, you will need to run a custom query to pull in the required posts. `pre_get_posts` does not work on page templates, so you will need `WP_Query` or `get_posts` to run a custom query
## EXAMPLE:
$args = [
'posts_per_page' => 6,
// Add any extra query parameters here according to
];
$q = new WP_Query( $args );
if ( $q->have_posts() ) {
while ( $q->have_posts() ) {

How can I relate custom post types?

Also the page that lists all the case studies for a particular product is very much like an archive page so it would be nice to be able to access it via
/productname/casestudies | There are probably several ways to handle this. I would store the parent product ID for each case study as post meta data for the case study.
