How can I get a comment ID on Submit?
I've added an attachment field to my comment form. It stores the files on Amazon AWS and writes the URL, user ID, post ID, and a few other things to a custom table. I'm having some difficulty getting the comment ID in order to properly associate the attachment with the comment. Is there a good way to get the comment ID as it is being written?
I've looked over the documentation and cant seem to find anything that would get my comment ID on submit. | You can hook `comment_post` and add your logic with the comment id
// Save the data along with comment id
add_action( 'comment_post', 'wti_save_comment_data' );

woocommerce stored variable
In wordpress, all information can be retrieved via `$post` or `wp_query`, in woocommerce, is there something similar? I want to display information of each product, on a page next to the picture. I have two questions.
1. How can i get to know, which variable does woocommerce uses to store the data.
2. In General, if we want to know the meta of any post,page, how can we pull it aganist each id, where id is generic (we don't know, its dynamic like `$post->ID`) | There is `$woocommerce`, which is is crucial. Several classes stored into this, see woocommerce class reference and additionally WC API Docs.
If you're looking for product information:
$product = get_product( $post->ID );
is certainly a good entry point. If you're already on a product page or generally in the wc loop, you often have `$product` already available.
Another thing to add is, wc product(s) are are just a custom post type, so you can do a lot by using wordpress core functions - like:
$all_meta = get_post_meta( get_the_ID() );
echo $all_meta;
But for some things you need or at least it's easier to use wc functions, to know these you have to read the plugins documentation, e.g. useful functions. Same applies to action and filter hooks.
Generally, take a closer look at the linked - and the not linked - information, the source and the variables/objects themselves to get deeper into that. | stackexchange-wordpress | {

Check if custom thumnail size image has been cropped to the correct dimensions
I'm looking for a way to check if an image has properly created a custom thumbnail size that has been hard cropped.
add_image_size( 'homepage-thumb', 1676, 828, true );
$size = "homepage-thumb";
echo wp_get_attachment_image( $attachment_id, $size );
This works well if the uploaded image is large enough but if it's smaller than the dimensions defined in add_image_size the aspect will be out which invariably breaks a layout. Is there a way to check the thumbnail before echoing the image? | $image_attributes = wp_get_attachment_image_src( $attachment_id, $size );
Returns an array containing:
[0] => url
[1] => width
[2] => height
[3] => boolean: true if $url is a re-sized image, false if it is the original.
Even though you pass the $size as parameter, while returning; it returns the actual width and height of the image irrespective of the image being cropped or not. Then you can check for the width and height if these are smaller then the requirement. OR better apply min-width, min-height in CSS or jQuery. | stackexchange-wordpress | {

Posts and Pages not showing on admin, but showing in theme
I've just transferred a WordPress install over from and old IIS server set up by our client, to our new Lunix based VPS. Whether that is relevant or not, i'm not sure.
I've changed all the usual settings and database options i'd usual do on moving a website to a new/live server environment.. This has worked perfectly other than the data doesn't show in the WordPress admin specifically, but does if you visit www.lenstec.co.uk. That suggest the data is being successfully pulled in as it normally would.
My initial thoughts are that this may be a global variable somewhere within the theme that WordPress does not like?
Unfortunately, i've check through my function file and corresponding theme files and not come across anything.
Can anyone suggest something I may have missed? | That is Core code trying to use a Core function. You have almost certainly had a problem with the transfer.
1. Very carefully, re-upload all of the files. I expect some file is missing or corrupt.
2. And make sure that all of your permissions are correct.
It would probably be a good idea to disable plugins and switch to a default theme as well. Since you can't get into the backend you will need to remove or rename the theme and plugin folders via FTP.

how to hide home nav link in wordpress

How to hide first gallery for every post?
I'm using galleries for attaching images, so the very first gallery for every post is used to generate a slider and nothing more. That's why I don't want to see it in post's conent. Let's say I have a single post that looks like this:
[gallery ids="1,2"] // hide
[gallery ids="3,4"] // display
[gallery ids="5,6"] // display
Is there some way of blocking the very first gallery from the content for every post?
#gallery-1 { display: none !important; }
works good but is ugly as hell :) Also it only hides the gallery but it's still there, same goes for it's JS. | You could use `preg_replace()` but I think it's much easier to overwrite the `$output` via the `post_gallery` filter and then remove the filter after the first run:
/**
* Remove the output of the first gallery
*
* @param string $output
* @param array $attr
* @return string $output
*/
function wpse125903_remove_the_first_gallery( $output, $attr )
{
// Run only once
remove_filter( current_filter(), __FUNCTION__ );
// Override the first gallery output
return '<!-- gallery 1 was here -->'; // Must be non-empty.
}
add_filter( 'post_gallery', 'wpse125903_remove_the_first_gallery', 10, 2 );

Importing Existing Users with Passwords
I have an existing legacy PHP site of 15000 users with base64 hashed passwords , I would like to import all these users into the new wordpress site with their passwords , What would be the best approach to realize this?
Praveen | You can use `wp_insert_user`. Since your old database has passwords in base64, you can easily get the original password string using `base64_decode`.
$new_user_data = array(
'user_pass' => 'password',//pass your decoded password string
'user_login' => 'username',//pass your username
'user_email' => 'email',
'first_name' => 'firstname',
'last_name' => 'lastname',
'role' => 'author'//if you want to specify a different role other than default one
);
wp_insert_user( $new_user_data );
You need to format your old data in csv or xml or text file and read and pass them accordingly. And don't try to import all 15000 users at once. Do this in several parts. Also `sleep()` function will be quiet good to give the server some rest. | stackexchange-wordpress | {

Multitenant with a single site
**What are the best practices to create a multitenant enviroment in wordpress?**
I've created an app with wordpress. Now i would like to make it as a multitenant solution. I've ended up with two options:
* Create a multisite registration and use the wp network solution (each tenant is a site - a lot of dbs / separated content )
* Single site and use authors on queries (tenant content not well separated / single wp db)
The app is the same for everyone, all interfaces, content types, available options are the same. | Before I learned about Wordpress network solution I went with option two - setting up certain privileges to users to be able to view and edit content only authored by (and for) them. That can be accomplished by using almost any WP plugin that allows you to change permissions per user, and a few functions that will change how and when things like attachments, post/page count, media library appear. It's manageable, but also a bit of a hassle.
Having recently done a similar thing with WP network, I have to say it's an easier and cleaner solution that already handles most of the issues you would come across using single WP installation. Note: Network doesn't require separate databases from you, merely tables under the same database.
That means that you can query content from other sites (blogs) to avoid its repetition.
All in all, I'd say that for this purpose:

Can plugin variables cause conflict?

class Pluginname {
...
}
}
if (class_exists("Pluginname")) {
$obj = new Pluginname;
}
Question: What if `$obj` is already used in Wordpress code or in another plugin? Can this be a potential source of conflict? If so, what to do? | They can. Say you have plugin one, with only this:
// Plugin one
$variable = "henk";
And then you have plugin two, with only this:
// Plugin two
echo $variable;
And now you activate these plugins, you will probably see the variable of plugin one echo'd by plugin two (at least it did here, but I don't know what determines the sequence).

Do WordPress cron jobs slow down page loading?
If a user visits a site and his visit triggers a cron job that is quite intensive, the page load speed will be slower for him right? As I understand the page doesn't wait for the cron job to execute before loading, but since the cron job would be running in parallel, it might still be the case that the page loads slower since the server is busy right? | Short answer - **Nope**. Any page request initializes the scheduled queue. It's just an initialize request. Wp-cron request is a standalone request.
> so requesting URL `/somepage` you just initialize request to `/wp-cron.php`
However - If cron event doesn't work really well (it's has 1000 db queries e.g. or its requesting a some really long-to-respond resource), or both, or re-scheduling cron event for each request... just like any other http request it will eat resources, CPU performance, memory, etc... if it eats enough resources, your page will become slower. | stackexchange-wordpress | {

Save wp_editor() content as option
I'm having some troubles with a extra feature i'm writing for my theme.
The admin should be able to make some special posts, those posts are stored as an option. The options are atored as an array and WP makes it's own json for arrays.
So, the user has a wp_editor(), and the array stored looks something like this:
array(
'title' => 'My title',
'content' => 'Look at my cat! <img src="mycat.jpg" />', //Generated by wp-editor
'signature' => 'My name'
);
The thing is, when an image is added to this content, the image string is quite badly escaped. When i'm trying to get this content i get it as
<img src="\"mycat.jpg\"" />
instead of
<img src="mycat.jpg" />
How can i store content like this in the wp-options table so i can get it right when i try to get the content? | If you just want to get rid of the `\` characters in the string that's returned, you can use PHP's `stripslashes()`:
$content = stripslashes( $content );
I'd recommend doing this on output rather than on input; WordPress adds the slashes as it sanitizes your data on insert, per `update_option()`'s Codex page,
> The `$option` (option name) value is escaped with `$wpdb->escape` before the `INSERT` statement.

Help setting up a sql query
I need to list out specific custom field items that contain an associated custom field entry. For example, the custom fields are named "type" and "food". I would like to list out all of the breakfast foods. "Breakfast" being the "type" custom field and "bacon", "eggs", "biscuits" being the "food". Right now, I have this query, but it lists out every type of food when I need it to list out only the breakfast types.

add_rewrite_rule to search
Newbie WordPress developer here.
I need to map a WordPress URL like this `www.example.com/user/Username` to a search result based on that Username
I already have the page that makes the search with the url `www.example.com/search-results/?name=Username`

"user/([^/]*)",
"search-result/?name=$matches[0]",

}
But this is not working and the rule is going to `non_wp_rules`. | That's going to the non wp rules because you're not mapping the URL to the index.php page format.
If you want it to be a WP rule, then you need to start the destination with index.php and include the query string to define what you want the query to contain.
So if you wanted it to go to a specific Page, for example, then you could set it as:
`index.php?page=123&name=$matches[0]`

Why is 'pre_get_posts' having no effect?

}

From what I have read, I cannot see anything wrong with this, but when I run this below it:
echo get_query_var( 'posts_per_page' );
it displays the default '10', rather than the '1' I was expecting. Am I doing something wrong? The index page is entirely empty apart from the above code. Cheers for any help. | > ... It's a very simple piece of code on the **index** page of an otherwise empty theme...
If you are running this code on the **_index page_** of your theme and expect it to effect the main query, then you are adding the action too late. The main query runs well before your theme template loads. You will need to put that code in `functions.php` in your active theme or in a plugin and use some conditional logic to make sure that it runs only where you want it too. For example...
function just_one( $query ) {
if ( $query->is_main_query() && $query->is_front_page() ) {
$query->set( 'posts_per_page', 1 );
}
}
add_action( 'pre_get_posts', 'just_one' );

Check if custom taxonomy has posts with get_categories()
I'm using **get_categories** to list all the terms of my taxonomy " **genre** ", but I have other taxonomy called " **brands** ".
In Brands page ( **taxonomy-brands.php** ) I need to return all the posts from the brand and the genre they're related.
**For example, I have a taxonomy page for Ferrari:**
. Brand name: Ferrari
.. Genres: Red, Yellow
**But I also have a taxonomy page for Wolkswagen:**
. Brand name: Wolkswagen
.. Genre: Blue, Green
The problem is that Ferrari page, is also listing "Blue" and "Green", even if Ferrari doesn't have any posts related to Blue and Green.
Finally, is there any way to hide "Blue" and "Green" when they're not used?
Here is what I got so far: <
If you need a visual example: \- "Sucos" and "CD" should not appear, since this brand only has posts with "Macarrão Instantaneo". | Category objects returned by API have count of posts on them in `count` field. You should simply check that and skip rest of the iteration for those that have no posts.
Something like:
foreach( $categories as $category ) {
if( 0 == $category->count ) {
continue;
}
Scratch that. If I get it right this time what you really need is to check if you got any posts before you output category header. Something like (don't use `query_posts()` by the way, it's trouble):
$stuff = new WP_Query( $args );
if ( $stuff->have_posts() ) {
?><a href="#" class="list-group-item active"><?php echo $category->name; ?></a><?php

Displaying categories items among posts
I'm making a website with lots of custom posts as well as custom hierarchical taxonomies. Default index (archive) page is made of bricks with photo, title and excerpt from posts. And here comes the problem, cause those index/archive pages mustn't contain only posts items (bricks), it should also contain (among the normal post items) bricks showing sub-categories of current.
Is it a good way of doing such a thing using categories, and if it is - how to achieve it?
EXPLANATION EDIT: By bricks i understand floating containers, just the visual representation of post (or category) data. Floating thumbnails with descriptions.
Category archive page would contain items of two types: 1) posts located in current category (not subcategories) and 2) subcategories of current category. It'd be kind like files and folders structure. | Okay, after a research of a matter, i came to the conclusion. My post types would either be the category posts with no data (parent containers) or a child posts - standard articles. My template will check if the post does have any children - if not - it will display the post itself, and if yes - it will display gathered bricks (thumbnailed excerpts) of them.

)
);

To clean up the entire table, open a SQL console (the plugin Adminer has an UI for that) and type:

Or … you could use an existing anit-spam plugin with open source (Antispam Bee and/or T5 Spam Block for example) and run all your comments through their filters. In a secound round, find all IP addresses marked as spam already and delete all comments with matching IP addresses.

Display the current post author and his url in the post header
I'm making some changes in my theme. I want that when they visit a Post the header should contain the post author and his URL. right now I'm using this:
echo '<a href="'.get_author_posts_url().'">'.get_userdata($posts[0]->post_author)->data->display_name.'</a>;
the auhtor's display name is working correctly, but the link is going like
www.mysite.com/?auhtor=0
instead of this (for example)
www.mysite.com/?auhtor=36
so this is the code in the header
<a href=" name</a>
instead of this:
<a href=" name</a>
by the way: I'm doing this outside a loop. | for anyone who's having this problem,this is the code I used:
echo '<a href="'.get_author_posts_url(get_userdata($posts[0]->post_author)->data->ID).'">'.get_userdata($posts[0]->post_author)->data->display_name.'</a>'; | stackexchange-wordpress | {

multiple language website navigation menu suggestion
I have completed a single page wordpress theme. I have to add the feature of multiple languages to it. So what I have decided is to make the user create a page such as about-gr Which gr stands for Germany. The website has a navigation menu, which loads the content of the page via ajax. in my jqueyr ajax call, if they selected germany as the language i append -gr to the link and load the page about-gr. it works fine. But the issue is how can I change the language of the menu.
* _Should the user create multiple menus for each language and load the relevant menu? I find this difficult to handle for the user. Is there any other way of changing the language of the menu? *_ | > Should the user create multiple menus for each language and load the relevant menu?
Yes
Obviously menus are part of the content of the site, and no one else except for the site owner can decide what will be the content.
> I find this difficult to handle for the user. Is there any other way of changing the language of the menu?
Sure, localization is hard. You can use the google translate API to translate automatically. IMO this approach is not recommended to any site that don't want to be ridiculed (google translate is good enough to give a general meaning of phrases, but from time to time it will give you a funny translation that is out of context).
side note: you are reinventing the wheel. This kind of localizations is usually solved by using dedicated plugins like WPML or by setting different sites (maybe over a network installation) per each language. | stackexchange-wordpress | {

How to get the real file type for images that do not have an extension
So i have a front end form that let users upload images from an URL...
Everything its ok when the image URL have the proper extension like this:
<
but when the image url doesn't have an extension like this :
<
My code doesn't work.
This is how i get the extension:
$filetype = wp_check_filetype($imageurl, null);
Now, if the file name of the image retrieved does have an extension, say jpg, then the output of the above call is
Array
(
[ext] => jpg
[type] => image/jpeg
)
However if the extension is not part of the file name then the call above returns the following array
Array
(
[ext] =>
[type] =>
)
How can i get the real file type for images that do not have an extension? | I think, you can not exactly determine, but you can assume one with header data.
$headers = wp_get_http_headers( $url );
$mime_type = $headers['content-type'];
$ext = '';
foreach ( wp_get_mime_types() as $exts => $mime ) {
if ( $mime == $mime_type ) {
$ext = $exts;
break;
}
}
Now in the `$ext` variable, it could be multiple extensions that have been matched, and there's no way to determine which one the image actually have. But, you could try the first one.
if( $ext ){
$exts = explode('|', $ext);
$ext = $exts[0];

jQuery Live Form Validation in Wordpress
I'm trying to implement the form validation that can be found at: <

jQuery("#firstname").validate({
expression: "if (VAL.match(/^[A-Za-z '-]{3,20}$/) && VAL) return true; else return false;",

});
});

How do I use Mac Keyboard Icons in WordPress

Thanks in advance! | The answer is rather simple – you type them. :) When properly configured WP should be able to support Unicode characters for `⌘` and `⌥`. Even when not you can fall back to numeric character references (`⌘` and `⌥` respectively).
Windows key has no Unicode symbol and is typically abbreviated as `Win`.
`<kbd>` HTML element is appropriate to use for keyboard commands and is often already styled in theme (if it is thorough enough). | stackexchange-wordpress | {

the_content();//by this am getting the medium sized images from the post content as it is uploaded through add media

Now i want to show full size of the image for each post. How to do it.
can anybody help? | Since you say that your image is "uploaded through add media", you need to select the full sized image when you attach it to the post, not when you try to display it. You should even see in the markup that a smaller size has been chosen (by you).

<
instead of the YouTube page:
<
in your embed code.
**2)** You can always use the `[embed]` shortcode if you need to embed YouTube videos:
[embed width="600" height="400"]
**3)** You should consider adding a _prefix_ to your shortcode callback, for example `macko_tarana_` to avoid function name collision with other plugins.
**4)** Try to avoid `extract(...`, use `$atts = shortcode_atts(...` instead.
**5)** Consider atting the third parameter to `shortcode_atts`, i.e. the shortcode name so you can use the `shortcode_atts_{$shortcode}` filter. More about it here in the Codex.

3.8 Media Upload and Custom Meta Box

Content area is too small
I want to change to the new twenty fourteen theme because it's a nice look and feel. However if I try so the content is reduced only on a small area and a lot of space on the page is unused.
I already tried this: how to create a conditional content_width for a wordpress theme? but it does not help me at all.
to give you an image of what i mean look at this: Unused pagearea marked in yellow
Some of you know where and what do I have to change to fit the whole area?
My blog: www.sysstem.at | You need to edit your theme's CSS to do this.
In style.css in your 2014 folder on line 1021:
.site-content .entry-header,
.site-content .entry-content,
.site-content .entry-summary,
.site-content .entry-meta,
.page-content {
margin: 0 auto;
max-width: 474px;
}
change 474px to whatever you want your content width to go up to. Or set it to 100% to stay full width. | stackexchange-wordpress | {

Should I put my plugin javascript inline?
I have a small bit of (localised) Javascript bundled with a plugin. Currently it's in a non-minified .js file, called at via enqueue_scripts.
Given that this script will likely run on every page, should I minify it or output it so it's inline in the page? | If you minify it you'll be able to reap the advantage of caching the file.
If you inline it, the browser will have to download the script every time it accesses a page with your plugin on it.

How to display recent posts added in custom post types
I have tried a code posted here>>Custom Post Type: Get most recent permalink
But the thing is-it is showing only one post from the recent and without get_the_title,,, can anyone help me to achieve, upto 10 posts' Title and permalink of custom post type.
I am googling from about 1 hour.. Please anyone help me | The answer is essentially in Codex!
<h2>Recent Posts</h2>
<ul>
<?php
$recent_posts = wp_get_recent_posts(array('post_type'=>'book'));
foreach( $recent_posts as $recent ){
echo '<li><a href="' . get_permalink($recent["ID"]) . '" title="Look '.esc_attr($recent["post_title"]).'" >' . $recent["post_title"].'</a> </li> ';
}
?>
</ul>
The only thing I did was add an argument to search for the `book` post type instead of the default `post` type.

get_template_part() to render single page Theme
I´m developing a single page theme and want to render all pages with their respective templates on a single page. I know I could make a query and write the markup for the respective page, but I prefer separate all templates in files. What I want is to make the loop and load the template-*.php file for each page. Is that possible?
To clarify this a little bit, below follows an example of what I want:
$query = new WP_Query();
$wp_query->query('post_type=page');
while ($wp_query->have_posts()) : $wp_query->the_post();
get_template_part('templates', 'template_slug');
endwhile;
and in the while loop output not only the content, but the content in teh right markup.
Any help is more than appreciated! | Something like this if you want to call mytemplate.php:
get_template_part( 'template');
Or something like this if you want to call content-mytemplate.php:
get_template_part( 'content', 'mytemplate' );

How to display data from db in select list
I wonder what it's wrong in my code. I can't get all of data in column "adres". In result I only have the lest record. Thanks for help.
global $wpdb;
$result = $wpdb->get_results ("SELECT adres FROM wp_ow_adres;");
foreach ( $result as $result )
echo '<td><select id="adres" type="text" name="adres">
<option value="">Select your address</option>
<option>'.$result->adres.'</option>
</select></td>'; | You're recreating the select element on every iteration through the loop, and you need to name your current loop assignment variable differently, as you're overwriting your original.
Lastly, you're also not assigning a value to the options within the loop, so you're not going to get anything on the form submission, and text isn't a valid type for a select element.
Try this:
global $wpdb;
$results = $wpdb->get_results ("SELECT adres FROM wp_ow_adres;");
echo '<td><select id="adres" name="adres">';
echo '<option value="">Select your address</option>';
foreach ( $results as $result ) {
echo '<option>'.$result->adres.'</option>';
}
echo </select></td>';

Is this plugin being loaded before file.php, subsequently not allowing me to use certain functions?
I'm trying to use `get_home_path()` in my plugin, however, I get a _`call to undefined function`_ fatal error (running Wordpress 3.8).

Is it just me, or is that a little odd? How can I make file.php load first so I can access this function?
The line of code that causes this issue (within my plugin) is:
register_theme_directory(get_home_path().'/material/views'); | to make sure everything required is loaded before plugins loads, use plugins_loaded hook and initialize your plugins its callback funtion. for example:

WP 3.8 theme customizer error

Setting a new default template for the creation of a page

Help with changing style of the extended menu drop down
I am trying to change the style of the extended menu drop down from being on the right side to the left side. As you can see by the picture provided, the menu item named "Catholic Women's league of Canada" comes down on the right side.

Assign SQL 'post_thumbnail' column as featured image
I have added a column called `post_thumbnail` to my wp_posts table.
Is there any way I can make `post_thumbnail` to each post's featured image? | How is the post_thumbnail information stored?
If you've already created an attachment with the image and are storing the attachment's `postId` in `post_thumbnail`, then you just need to go through your posts and update the meta using `update_post_meta($postId, '_thubmnail_id', $attachmentPostId)`.
If `post_thumbnail` stores the path to an image file on your server, you need to create an attachment using wp_insert_attachment and pass in that file location. If the files are not already stored in the uploads directory, you can use the Add From Server plugin to import the files into wordpress as attachments. You can then use `update_post_meta` to set the attachment as your featured image.
If `post_thumbnail` stories the URI of the image, you need to save it to your server, then create the attachment, then update the post's meta. | stackexchange-wordpress | {

Recommended Media Size for Twenty Fourteen
is there a recommended media size for Thumbnail size in twenty fourteen? am trying to sort out my website so that it doesn't serve any resized media on the home page, most of the resized media are coming from the featured image on the home page. When i test the page speed i get "The following images are resized in HTML or CSS"
Any help on the thumbnail media size wold be greatly appreciated. | Twenty Fourteen uses 2 custom media sizes:
* 672x372px for post thumbnail image size
* and 1038x576px for 'twentyfourteen-full-width' custom image size
So for images uploaded _after_ the theme is activated, these 2 size are created automatically, but for images uploaded _before_ twentyfourteen is activated, an available size is used and image is resized via html/css properties.
What I suggest is for new images upload files having width >= 1038 px and height >= 576 px and let theme resize them.
For images already uploaded a plugin like Regenerate Thumbnails can be very usefull (but images must be larger than custom size required by theme or the thumbnail will not be generated). | stackexchange-wordpress | {

wp_head hook content showing up at top of RSS feed
The RSS feed for a site I maintain recently stopped working. I did a little investigating and found that the `wp_head` hook contents of several plugins is getting injected at the top of the page, causing an XML parse error (obviously).
I'm really not sure what the problem is. I'm not really familiar with how WordPress generates its feeds, so I don't have much insight there.

I don't know for sure though, it certainly could be a 3.8 bug.

When every plugin is disabled, the feed works, because nothing is hooking onto the `wp_head` hook that's causing the problem. | The wp_head hook is not normally called for feed generation, so you need to find which plugin or other piece of code is adding that to the feed.

Instantiate class to be available to all plugin functions
I'm developing a plugin for a site that has to communicate with several non-wp tables in a database. For that I made a class that contains all of the MySQL-related functions.
When you declare a function within a plugin, you can easily call it within a theme. But how to do that with a class? Is there a way to instantiate it with wordpress init and make it available to plugin(s) and theme(s)?
Thank you for your time! :) | Ryan McCue had a nice idea for his plugin Hopper: add a callback for a custom filter to return the current instance.

{
add_filter( 'get_plugin_class', array ( $this, 'provide_instance' ) );
}
function provide_instance() {
return $this;
}
}
In a theme or a second plugin you can access the instance now like this:
$plugin_class = apply_filters( 'get_plugin_class', NULL );
if ( is_a( $plugin_class, 'Plugin_Class' ) )
{
// use the plugin class instance
