Can't Find Documentation For wp_styles in WordPress - wordpress

I'm seeing references to properties on global variables that I can't seem to find any documentation for in WordPress. For instance $wp_styles->queue and $wp_styles->registered , see this answer which contains similar code to the below:
function inspect_scripts() {
global $wp_scripts;
print_r($wp_scripts->queue);
}
add_action( 'wp_print_scripts', 'inspect_scripts' );
function inspect_styles() {
global $wp_styles;
print_r($wp_styles->queue);
}
add_action( 'wp_print_styles', 'inspect_styles' );
However when I try to find documentation for these properties in the codex for WP_Styles there is no mention of those properties. I also don't see a mention of these globals on the WordPress globals page. Where are people getting the information they need to write/use this code?

WP_Styles extends WP_Dependencies, and WP_Dependencies is where you find ->queue, ->registered, etc.

White page by using the filter template_include

I working on my plugin and tried to override some templates.
If I visit the page portfolio my screen gives a whitepage.
This is my code
define("PLUGIN_DIR_PATH", plugin_dir_path(__FILE__));
add_filter( 'template_include', 'plugin_tweak_template', 99);
function plugin_tweak_template( $template ) {
if ( is_page('portfolio')) {
$template = PLUGIN_DIR_PATH . 'required/templates/portfolio.php';
}
return $template;
}
I use this code in my plugin root file.
I think the define path has a conflict.
define("PLUGIN_DIR_PATH", plugin_dir_path(__FILE__));
PLUGIN_DIR_PATH is a example in many tutorials but you can define this one time.
Is you have another plugin check the define name from this plugins if this is the same name you have a conflict.
Remember always: use variable names etc. by your own and prevent issues.

Deleting a Wordpress user using a custom plugin Hook

I am new to wordpress hooks and I am trying to delete a wordpress user using a custom action the plugin Restrict Content Pro provides.
(https://docs.restrictcontentpro.com/article/2054-group-accounts-actions-filters)
What I want to achieve: When a member is removed from a group, their account should be deleted.
Unfortunately my code doesn't work. Any ideas on how to modify it be highly appreciated!
function delete_group_user() {
wp_delete_user($user_id->ID );
}
add_action( 'rcpga_remove_member', 'delete_group_user' );
You are close, your function delete_group_user() does not have $user_id defined. Luckily, it looks like the rcpga_remove_member hook provides that information. Something like this should work:
function delete_group_user($user_id) {
wp_delete_user($user_id);
}
add_action( 'rcpga_remove_member', 'delete_group_user' );
Also, note from the documentation that $user_id is an INT not an object.

Wordpress: Plugin for simple user profile pages

In WordPress, I am aware that tld.com/author/username exists for authors, but I am looking for a public user profile page for non-authors. I want to setup a simplistic "favorite's list" for members on my site. Users will create an account, and add posts they like. They don't need access to wp-admin.
I'm looking for something simple like tld.com/user/username -- not /user/?uid=1. Nice and "pretty". Just like how WordPress handles /author/admin, or /author/username.
I would also like to keep /authors preserved so that's accessible too.
I have tried many plugins like WordPress-Users, but it's not a "pretty" URL, also have tried complicated plugins like Members, profile-builder, wp-user-frontend.
I found the answer to this from #bybloggers answer found here. https://wordpress.stackexchange.com/a/58793/12920
I modified his code very slightly to tailor it to my needs, but this is the code that worked for me and was exactly what I was looking for:
// Create the query var so that WP catches the custom /member/username url
function userpage_rewrite_add_var( $vars ) {
$vars[] = 'member';
return $vars;
}
add_filter( 'query_vars', 'userpage_rewrite_add_var' );
// Create the rewrites
function userpage_rewrite_rule() {
add_rewrite_tag( '%member%', '([^&]+)' );
add_rewrite_rule(
'^member/([^/]*)/?',
'index.php?member=$matches[1]',
'top'
);
}
add_action('init','userpage_rewrite_rule');
// Catch the URL and redirect it to a template file
function userpage_rewrite_catch() {
global $wp_query;
if ( array_key_exists( 'member', $wp_query->query_vars ) ) {
include (TEMPLATEPATH . '/user-profile.php');
exit;
}
}
add_action( 'template_redirect', 'userpage_rewrite_catch' );
After this was in my functions.php file, I had to re-save my Permalinks.
Sometimes re-saving the permalinks didn't finish the job 100% and browsing to www.mysite.com/member/username would 404, so I had to manually flush the rules by putting this into my functions.php and loading my site once. Then removing it so I don't run it every time the site loads, since that's unnecessary overhead.
// Code needed to finish the member page setup
function memberpage_rewrite() {
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
add_action('init','author_rewrite');
I don't know if you will find this one, at least not for free. Have you checked out WPMU? I started writing a membership plugin a few months ago but never completed it and am now doing it in Symfony. Most WordPress membership plugins are either too complex to use or don't provide the features you need.
You should spec out what you need an get a local dveloper to build it for you, you might even be able to sell it if you do a good job.

Custom post type functions.php if statement on action

I am using developing a child theme for Woothemes' Canvas.
I am trying to use functions.php in the child theme to only use actions on my custom post type.
This code doesn't seem to be working:
add_action( 'woo_post_inside_after', 'my_geo_mashup' );
function my_geo_mashup() {
echo GeoMashup::map();
if ($post->post_type == 'listings') {
//My function
}
}
add_action( 'woo_post_inside_before', 'listings_nivo' );
function listings_nivo() {
echo do_shortcode('[nivo source="current-post" ]');
if ($post->post_type == 'listings') {
//My function
}
}
So, I'm unsure how to get the above to work properly and only show these items on the custom post type, or only for the custom post type template single-listings.php (as I only want the map and slider to show on the actual post, not on the blog page (archive.php)
Rather than making the entire $post object global, you can just make $post_type global instead. Ex below.
I'm not exactly sure where that function is being loaded, but make sure you hook somewhere within the post. If the action is before, as far as I know and from experience, the post variable will be null.
Just as a test, try running the action in wp_footer Ex. add_action( 'wp_footer', 'listings_nivo' );
See if that yeilds any results.
if echoing var_dump($post) is still null, well, not sure where to go from there.
So you can try running the below, then run the action in the appropriate place if it works:
function listings_nivo() {
echo do_shortcode('[nivo source="current-post" ]');
global $post_type;
// Diagnostic purposes
echo var_dump($post_type);
if ($post_type == 'listings') {
//My function
}
}
add_action( 'wp_footer', 'listings_nivo' );
Check your error log or turn wp_debug to true in your wp-config.php file if nothing else to see if anything else is going on.
Best of luck!
Inside your function, try adding global $post;. Then to see what you are getting with $post->post_type echo it out to the screen. As long as this gives you "listings", your code should work. If not, there's probably another issue at play.

Wordpress - How to include() a file that lies in another dir

I am writing a plugin that will take advantage of other plugin's features (think about a plugin for a plugin).
My file lies in /plugins/new-plugin/new-plugin.php
and I need to make a
include(/plugins/OLD_plugin/old-plugin.php)
so I can use a couple of functions from the old-plugin.php file.
What is the correct way to do this? I could maybe make the functions in old-plugin.php available globally, but I don't want to change the old-plugin.php file.
I've already tried several ways to do this, but none worked. The new-plugin will only show some info in an options page, not viewable for the general public and does not interact with any public page or post in my site.
I've already tried $_SERVER, WP_PLUGIN_DIR, WP_CONTENT_DIR, the absolute server path, relative paths and even some black magic, but nothing seems to work good.
With some of this solutions the plugin's options page shows good but the blog's pages do not render. With other solutions the inverse happens, and with some other solutions nothing even render, be it admin pages or blog's pages, all with errors regarding to file not found.
The new-plugin.php is as simple as
<?php
/*
WP Common Headers
*/
global $wpdb;
if ( ! defined( 'WP_CONTENT_DIR' ) )
define( 'WP_CONTENT_DIR', ABSPATH . 'wp-content' );
if ( ! defined( 'WP_PLUGIN_DIR' ) )
define( 'WP_PLUGIN_DIR', WP_CONTENT_DIR . '/plugins' );
include '/server-absolute-path/public_html/gameblogs/wp-content/plugins/old-plugin/old-plugin.php';
add_action('admin_menu', 'new_plugin_menu');
function new_plugin_menu() {
$page_title = 'New Plugin';
$menu_title = 'New Plugin';
$function = 'new_plugin_admin_page';
$menu_slug = 'new_plugin';
add_menu_page($page_title, $menu_title, 0, __FILE__, $function);
}
function new_plugin_admin_page() {
$result = old_plugin_link_data(" WHERE link_destination NOT LIKE '/%' AND link_destination NOT LIKE '%gameblogs%'");
$total = count($result);
old_plugin_list_links($result, $total, FALSE, FALSE);
*/
}
?>
thanks for any ideas!
check the old plugin files and see if there are any do_actions or apply_filters in it. If there are then you can hook into the old plugin script with your new plugin using add_action and apply_filters and execute other things you want to do.
see http://codex.wordpress.org/Function_Reference/do_action
and http://codex.wordpress.org/Function_Reference/apply_filters
For example (very basic example):
If in old plugin you find a:
do_action('some_type_of_reference);`
In your new plugin you can hook into it by doing:
`add_action('some_type_of_reference', 'name_of_my_function');
function name_of_my_function() {
//executed code here
}`
If in old plugin you find a:
apply_filters('some_type_of_reference', $variable);
Then in your new plugin you can hook into the filter by doing:
apply_filter('some_type_of_reference', 'my_function');
function my_function( $variable ) {
//act on the variable from the filter.
return $variable;
}
Have you looked at the plugins_url function? I haven't had an in-depth read through your code, but it might help.
The plugins_url template tag retrieves the url to the plugins directory or to a specific file within that directory. You can hardcode the plugin slug in $path or pass FILE as a second argument to get the correct folder name.
Hope this helps!
