Does WordPress send data about your blog back to Automattic or somewhere else?
> **Possible Duplicate:**
> Does WordPress send data about your blog to WordPress.org or Automattic?
I've recently heard someone say that WordPress sends data about your blog to home (where ever that is). Is that true? and if so what is sent away or where in the code can I see what's exchanged? | This is true to a degree. They probably do this for a few reasons but most likely to help monitor bugs and things like that in regards to future improvements and updates. Nothing malicious to worry about! They need to keep track of versioning especially so that you can be notified of updates to WordPress itself as well as themes and plugins.
Your WordPress installation syncs up every 12 hours. A few things they keep track of: wordpress version, php version, locale, whether multisite is enabled, etc.
You can get a much better understanding of what they are tracking if you check out `includes/update.php` in your WordPress installation as everything is outlined in that file. | stackexchange-wordpress | {

How to restrict a plugin from certain pages without editing its core
I've run into a problem using two different twitter plugins. One is for login and one is for displaying a twitter stream. The issue is they both use Oauth so I get a re-declare error when trying to login on my custom login template. Since I only use the twitter stream plugin on profiles I'd like to limit it's functions use purely to the profile but without actually changing the plugins core code. Possible? | I would approach as follows:
1. Identify all the action/filter hooks in the plugin
2. Identify all scripts/styles being enqueued.
3. Create a function that removes the actions/filters based on the page using `remove_action`, `remove_filter`, `wp_deregister_style`, `wp_deregister_script`
You could use something like the following:
function foo_disable_plugin(){
if(is_page('PAGE_TITLE OR ID')){
remove_filter('the_content', 'PLUGIN_FILTER_NAME');
remove_action('wp_head', 'PLUGIN_ACTION_NAME');
wp_deregister_script('PLUGIN_SCRIPT_NAME');
}
}
add_action('template_redirect', 'foo_disable_plugin', 999999999);
If this doesn't work, you're probably going to have to make one of the plugin's classes pluggable.
if(!class_exists('CLASS_NAME')){

remove page template from dropdown?
I created a page template, uploaded it, but then changed the template name later.

Now, the new template name is showing up on the Page dropdown, but so is the old template name. How can I delete the old one from the list?? | Just remove the old file from your theme's directory.

Hook when new CPT published AND postmeta inserted
I would like to know if there is a hook that fires when a new CPT is published and its postmeta has been inserted.
I was using publish_mycpt but found that the postmeta wasn't being saved at that point. I would like my hook to run only for this custom post type, not for all posts.
The function I will be calling via the action hook is also used by a scheduled cron job, so it's not only called when a new post is published via the administration interface, not sure if this is important or not. | I believe you can do it using the save_post hook, than do a conditional check for the post's post-type and the value of its post meta.

echo post-permalink without http and www

Don't get me wrong, this has nothing todo with rewriting permalinks or whatsoever. Just a simple echo of `the_permalink()` on my page that is not handled as link but as normal text.

changing theme folder name breaks menus - twentyeleven
I needed to change the twentyeleven theme folder name, so I activated the default theme, changed the twentyeleven folder name to X, then reactivated it. Everything worked except the menus were all in the wrong places. I figured out they needed to be redefined in Menus>Theme Locations. But now, there's an extra sitemap listing in the footer.. I didn't put it there and can't figure out how to get rid of it. It's listing out the sitemap in ul tags, twice. Any suggesions? | Try going to **Dashboard -> Appearance -> Menus** and re-applying your custom menus to the appropriate Theme locations.
By changing the directory name, you've impacted the `theme_mods`, including custom menus. To WordPress, **`/wp-content/themes/twentyeleven/style.css`** and **`/wp-content/themes/X/style.css`** are two different Themes, _even if all the files are the same_. | stackexchange-wordpress | {

Search functionality with multiple categories
Good day fine wordpress gurus,
I'm having a tough time writing a function that handles the search in a couple of user-selected categories. The way I'm presenting the categories is through the old get_categories method and I'm iterating through the array in order to build a category tree with checkboxes (client requirement).
So what I need is a hint of how to get the search in such a way that it includes the search term and the cat_ID's that the user selected in order to bring the relevant results.
PS: I already checked out Wordpress Multiple Category Search this link, and I didn't find anything useful. so please help. | Sounds like something Relevanssi could handle. With Relevanssi, you'd have the checkboxes to choose the categories. Then, you'd write a function to hook on 'relevanssi_modify_wp_query' filter, where you'd read the checkboxes and convert them to a comma-separated list of category ID's. That you would store in $wp_query->query_vars['cats'] and hey presto, Relevanssi gives you relevant results in those categories.
I think the same idea might work with default search, actually, but instead of 'cats' you'd use 'cat' and instead of 'relevanssi_modify_wp_query' you'd need another way to modify the $wp_query. | stackexchange-wordpress | {

adding a custom css class to post
essentially I need to be able to add a class to a post when it show in the list (say index.php) so when in the back end you can say oneCol, twoCol, threeCol and it will then output this within the loop post class.

You can setup a Custom fileds for that - See usage, then use `get_post_meta()` function to fetch it and show where you want

<?php echo get_post_meta($post->ID, "your_meta_name", true)?>

Wordpress do_shortcode first iteration
I've created a recursive shortcode that looks like this.
[tabs]
[tab state="active"]Home[/tab]
[tab]About[/tab]
[tab]Contact[/tab]
[/tabs]
[tabcontent]
[tabpane]Content 1[/tabpane]
[tabpane]Content 2[/tabpane]
[tabpane]Content 3[/tabpane]
[/tabcontent]
It is working, but I would like to remove the state="active" and automatically add that to the first tab, but I'm not sure how to tell which iteration my do_shortcode is on?
**Update:** What would be even better is if I could keep a count while iterating through the do_shortcode so I could add attributes like id="tab1", id="tab2". | Figured out both issues. You can keep a count and find out when you are on the first iteration in the same go.
static $count;
if(!$count) {
$count = 1;
$state = ' active';
} else {
$count++;
$state = '';
}
From the PHP Manual. "A static variable exists only in a local function scope, but it does not lose its value when program execution leaves this scope."
This code sets a static variable within the recursive function, in this case a function called by do_shortcode(). This lets you keep a count going so if you wanted to have id's like #tab-1, #tab-2 you could easily do so. With this code you can also tell when the first iteration happens. I set a $state variable and give it an active css class. Since I'm appending it to a class attribute already I've only got active, but you could also pass the whole thing if you only had one class like class="active" for example. | stackexchange-wordpress | {

Should multi-language site using multi-site architecture have default language in base site?

WordPress theme options vs custom post types
For dynamic content across a WordPress website, is it a better practice to create new post types for updating content or using theme options?
I personally find theme options a little more time consuming to code than registering a new post type in `functions.php` | It depends on the type of content.
Is the content dynamic, likely to change, likely to have repetitions of the same types of information, time dependent? I'll probably use a custom post type.
Is the content unlikely to change, or only needs one instance of the information set (like a logo, Google analytics code, social media usernames, etc)? Theme options.
There is another option that's sometimes viable: custom post meta-data. I'm working on a site right now where one of the pages has a list of FAQs set up in an accordion-style interface. My plan is to set up a custom meta-box specifically attached to just that page to hold the key-value pairs for the FAQs. This could be set up as a custom post type, but I'm setting it as custom post metadata. I figure this will be easier for my client, rather than having to learn, remember, and find yet another UI element. | stackexchange-wordpress | {

Do we have In_category like function for tags?
I have been using "if (is_single() && in_category('keyword') )" to display custom links on the sidebar. I was wondering if we have in_tag or any similar function for tags? | Here is the source of `in_category` function:
function in_category( $category, $post = null ) {
if ( empty( $category ) )

return has_term( $category, 'category', $post );

You see, it's actually `has_term`. This is the same as `has_category` function.
For tags, there's no `in_tag` function, but you can use `has_tag`. It has the same functionality:
has_tag( $tag, $post );
Or you can use:
has_term( $tag, 'post_tag', $post );
where `$post` can be omitted (default is current post).

How to get a meta value from all post
I searched for a while but I didn't find any solution. I used the functions listed here. It outputs something like this:
Array
(
[0] => 15
[1] => 30
[2] => 50
)

Array
(
[post_id_1] => 15
[post_id_2] => 30
[post_id_3] => 50

function get_meta_values( $key = '', $type = 'post', $status = 'publish' ) {
global $wpdb;
if( empty( $key ) )
return;
$r = $wpdb->get_col( $wpdb->prepare( "
SELECT pm.meta_value FROM {$wpdb->postmeta} pm
LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id
WHERE pm.meta_key = '%s'
AND p.post_status = '%s'
AND p.post_type = '%s'
", $key, $status, $type ) );
return $r;
} | `get_col()` function returns only one column as array. To get two column result we can use `get_results()`, Which will return an array of objects
Which further can be converted into required structure using foreach loop.
**Example -**
function get_meta_values( $key = '', $type = 'post', $status = 'publish' ) {
global $wpdb;
if( empty( $key ) )
return;
$r = $wpdb->get_results( $wpdb->prepare( "

WHERE pm.meta_key = '%s'
AND p.post_status = '%s'
AND p.post_type = '%s'
", $key, $status, $type ));

GUID not updated on import

Replace the slug of parent pages with #
I'm creating a Wordpress site with a Superfish CSS3 / Jquery dropdown menu, complete with hoverIntent as displayed here:
<
As far as I can see, this menu works well on mobile devices, because the link values refer to the same page, like `#a`, so that clicking a link does not cause the page to reload.
Please bear with me. I know that the right way would be to replace the dropdown menu entirely (with a select box or some other tool), but I need to have the exact same experience as on a desktop (long story).
My question is: how can I replace the href value of parent pages, with an internal link like `#a`?
My guess would be that doing this via jQuery would be the best solution. What are your views on this and could someone please provide a practical answer? Thanks in advance. | In my experience, Superfish actually does not rely on in-page links in order to show the submenus on touch devices (although admittedly I'm basing this solely on iOS devices).
Simply tap once on a top-level menu item and its submenu should show. A subsequent tap on the same top-level menu item would cause the browser to load that link. | stackexchange-wordpress | {

Can is_page() be combined with a switch control structure?
I'm using an if/else control structure to add class attributes to tags. Could I use a switch control structure instead and if so, how? If not, is there a better way to do this than what I'm doing?

elseif (is_page('home')) {echo 'class="home"'; }
elseif (is_page('contact')) {echo 'class="contact"'; }
?>>
</div> | While Ben's answer is basically correct, is_page also checks to make sure that the query is indeed a Page and not something else with the same post_name.
So to be 100% accurate, you could do something like this:
if ( is_page() ) { // only do this for actual pages
$page_obj = get_queried_object();
switch ( $page_obj->post_name ) {
// same switch as Ben's answer

How to make global post work with custom post type?

Providing a function to override the default query

the_post();

Loading post comments after clicking a button
Is it possible to load site comments on-demand instead of having them always display at the bottom of the post? Like by clicking on `Load Comments...`.
You can check **labnol.org**. They are using Disqus comment system which loads by clicking.
How could I achieve that? | You could try an easy jQuery approach of hiding the comments div and inserting a button to make it appear.
Instructions:
In your functions.php file of your theme, place this line of code to ensure that jQuery has been included to run the code:
wp_enqueue_script('jquery');
Then you could add this function to place the javascript code into the footer of each of your webpages:
function your_hidden_comments(){ ?>
<script type="text/javascript" defer="defer">
var comment_div = jQuery('#comments');
if(comment_div[0]){
jQuery('<button id="show_comments">Show Comments</button>').insertBefore(comment_div);
comment_div.hide();
jQuery('#show_comments').on('click',function(){ comment_div.fadeIn('slow'); jQuery('#show_comments').fadeOut('slow'); });
}
</script>

UTF8 Encoding problems when exporting posts

Users managed to register on website with no register button?
Due to recent spam, I wanted to stop registration on my website for a while.
But doing so meant the registration page would redirect to the homepage, which was bad for SEO.
So I left the registration page there, removed the 'register' submit button and put in a little message telling people to contact me if they wanted to be registered manually.
1 day later, I have another 5 users who somehow managed to register! All of these are spam users.
How did they do this?
I removed the 'register' submit button on the register page so did they manage to make their own submit button? (editing the webpage on their end)
Also if you go to mysite.com/wp-register.php or /wp-admin/ it asks for a password (.htpasswd protected).

Pagination stops at page 6

'posts_per_page' => '1',

<?php next_posts_link( __( 'Next') ); ?>
<?php previous_posts_link( __( 'Prev' ) ); ?>
<?php endif; ?>
<?php wp_reset_query(); ?> | Trying to use pagination from a different query is always fraught with potential disaster. `next_posts_link` accepts a second argument, `$max_pages`, which may solve your issue if you pass it properly:
next_posts_link( __( 'Next'), $idxloop->max_num_pages );
However, the _real_ answer to this question is to adjust your query _before_ the template. Adjusting the default query via a new `WP_Query` or by using `query_posts` is quite simply _doing it wrong_ , despite the millions of examples on the web you will see that do exactly that.
The preferred method for this is using a `pre_get_posts` action along with a conditional check to apply it to the specific type of query you want to adjust:

Settings API in Multisite - Missing update message
When I use the settings API in a multisite installation and the options page sits at the network level, posting the options to `options.php` does not work, because the administration page sits at `wp-admin/network` and WP expects the page to be at `wp-admin`.
I added a function that checks whether this WP installation is a multsite installation (via the constant) and if it is, it changes the form's action value to `../option.php`. This saves the options OK, but the default message "Settings saved." is missing (however, the query string does include `settings-updated=true`).
Any thoughts on how to get the message to appear? | For network option pages the correct form action URL is:
wp-admin/network/edit.php?action=your_option_name
Then you have to register a callback:
add_action(
'network_admin_edit_your_option_name',
'your_save_network_options_function'
);
In that callback function inspect the `$_POST` data, prepare the values, then save them:
update_site_option( $this->option_name, $this->option_values );
And then you have to create the redirect without further help:
// redirect to settings page in network
wp_redirect(
add_query_arg(
array( 'page' => 'your_options_page_slug', 'updated' => 'true' ),
(is_multisite() ? network_admin_url( 'admin.php' ) : admin_url( 'admin.php' ))

Use register_post_type() to modify an existing post type
There are lots of situations where a theme or plugin registers a post type and you want to modify it.

>
> Create or modify a post type.
But in the past, when I've try to do this, it hasn't seemed to work. Is this function really for modifying post types, and if so, can you simply redeclare a couple arguments and leave the rest alone?

How to Reload the Dashboard After Clicking Update in Quick-Edit?
How can I refresh the `wp-admin/edit.php` page after a user clicks **Update** in the _Quick-edit_ form? | I dug through WordPress' `wp-admin/js/inline-edit-post-dev.js` and found that there aren't any hooks for executing JS code after the quick-edit update.
I decided to override the `inlineEditPost.save` function from `wp-admin/js/inline-edit-post-dev.js`, similar to how WordPress recommends updating form data when the quick edit form is displayed (which overrides `inlineEditPost.edit`).
The full function can be found in `wp-admin/js/inline-edit-post-dev.js`. I just changed the callback function in the post call to reload the page instead of hiding the quick edit form.
(function($) {
inlineEditPost.save = function(id) {
//...
// make ajax request
$.post( ajaxurl, params,
function(r) {
location.reload();
}
, 'html');
//...
}
})(jQuery); | stackexchange-wordpress | {

Add column to plugins table screen
I'm trying to add a column to plugin table screen using "manage_plugins_custom_column", but without success.
This extra column will show a custom value that was placed inside the plugin file.
I hope someone could help!
Thanks! Daniel
\---------------- edit ----------------
This is the working code that creates the column "Version":
function add_plugins_column( $columns ) {
$columns = array(
"name" => __( 'Plugin', '' ),
"version" => __( 'Version', '' ),
"description" => __( 'Description', '' ),
);
return $columns;
} add_filter( 'manage_plugins_columns', 'add_plugins_column' );
function render_plugins_column( $column, $plugin_file, $plugin_data ) {
switch ($column) {
case "version": echo $plugin_data['Version']; break;
}
} add_action( 'manage_plugins_custom_column' , 'render_plugins_column', 10, 3 ); | First, you have to add the custom column to the plugin column names:
function wpa65189_add_plugins_column( $columns ) {
$columns['wpa65189_column'] = 'wpa65189 Custom Column';
return $columns;
}
add_filter( 'manage_plugins_columns', 'wpa65189_add_plugins_column' );
Then output your column data for your plugin:
function wpa65189_render_plugins_column( $column_name, $plugin_file, $plugin_data ) {
if ( 'wpa65189_column' == $column_name && 'My Plugin Name' == $plugin_data['Name'] ) :
echo 'My Plugin custom column data';

Hide Menu items base on capability
What is the best way to add/remove items for the `wp_nav_menu()` based on user roles?
For instance a custom menu that looks like:
* Some Page
* Some Other Page
* Special Admin Page
Where the `Special Admin Page` should only be visible for admin users.
Is this best done with `wp_nav_menu_items` filter or do I need a custom Walker?
This is a possible duplicate of: Hide menu items for visitors and filter based on role but that doesn't appear to have been completely solved. Though it does mention a tutorial about a custom Walker that seems relevant.
**EDIT:**
Based on Toscho's answer and How to add a custom field in the advanced menu properties? I combined the two to form my own plugin
Nav Menu Roles
Fair warning that I cannot vouch for its speed and I am relatively certain that it will not work _with_ another custom Walker, but it was a one-day plugin. | Create a custom walker. Redefine the method `start_el()` only:
function start_el( &$output, $item, $depth, $args )
{
if ( 'Your secret item title' !== $item->title
or current_user_can( 'administrator' )
)
{
parent::start_el( &$output, $item, $depth, $args );
}
}

fetch meta fields inside a widget
I'm trying to fetch a (date) meta field from a custom post type in a sidebar widget here: <
Somehow the date doesn't show correctly inside the widget (everywhere else I put it, also manually in the sidebar the code works fine). Anyone a clue?
The code looks like this:
<?php $loop = new WP_Query(array(
'post_type' => 'kurs',
'posts_per_page' => '5',
'meta_key' => 'dato',
'meta_value' => date('Y-m-d'),
'meta_compare' => '>=',
'orderby' => 'meta_value',
'order' => 'ASC'
)); ?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php $display_date = date('d.m.Y', strtotime(get_post_meta($post->ID, "dato", true))); ?>
<li><?php echo $display_date; ?> - <?php the_title( '<a href="' . get_permalink() . '" title="' . the_title_attribute( 'echo=0' ) . '" rel="bookmark">', '</a>' ); ?></li>
<?php endwhile; ?>
</ul> | I fixed this by adding:
global $post;
More specific: I can't explain why this works, that's beyond my WordPress skills, but I added it right after the start of the query, so the code looks like this:
<?php global $post;
$loop = new WP_Query( array(
'post_type' => 'kurs',
'posts_per_page' => '5',
'meta_key' => 'dato',
'meta_value' => date('Y-m-d'),
'meta_compare' => '>=',
'orderby' => 'meta_value',

Plugin - create a page without it appearing in the side menu
I am currently using add_submenu_page to add pages for my plugin. However, I wish to create a page that don't appear in the admin menu, is that possible? | Set the **`parent_slug`** property to **`null`** , example;
add_submenu_page(
null // -> Set to null - will hide menu link
, 'Page Title' // -> Page Title
, 'Menu Title' // -> Title that would otherwise appear in the menu
, 'administrator' // -> Capability level
, 'menu_handle' // -> Still accessible via admin.php?page=menu_handle
, 'page_callback' // -> To render the page
);
This will hide the sub menu page from your parent (top level) menu link.

Custom action on comment post
Whenever a user posts a comment, I'd like to basically have a copy of the post sent to another database for a separate site. The database part is simple, but I can't seem to find the right action hook for this. (I did my testing with a simple echo statement, a failure being it not displaying at all) 'comment_save_pre' would only work when updating a comment, 'wp_set_comment_status' only works when the comment is approved, and 'comment_post' didn't seem to work at all. Does the hook exist?
add_action('...?...', 'on_comment_post');
function on_comment_post($comment){
echo "Test";

How to disable the default WordPress redirect to non-www URLs?
I am trying to redirect all non-www to www URLs in my WordPress MultiSite install. I am using a simple `.htaccess` rule like this:
# Redirect non-www to www:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ [R=301,L]
Normally this would work, however WordPress already seems to have a default redirection to non-www URLs. This means that when I use that `RewriteRule` it causes an infinite redirect loop.
**How do I disable this?**
PS. I tried `define('NOBLOGREDIRECT', ' in `wp-config.php` with no effect. | Answer: Don't disable it, use it to do the redirection you want.
* If you have a subdomain install, then you cannot do this at all, the www is a subdomain.
* If you have a sub-directory install and want all the sites to be www, then edit your wp-config.php and change the DOMAIN_CURRENT_SITE to be your www domain.
* If you are using domain mapping, then use the domain mapping plugin to change the domain to have a www in it.
In the latter two cases, the point is that you're not using .htaccess to do the redirection, you're letting WordPress do the redirection to what it expects the URL is supposed to be. | stackexchange-wordpress | {

Comment number does not increment
I am making a custom wordpress theme and when I add a comment to a post and retrieve the number of comments using `get_comments_number()` the number does not change.
I do know the function works because for the first comment that gets preinstalled with wordpress it returns 1. but somehow the number does not increment if I add additional comments.
Is there a way to manually increment this number? Does anyone know what the problem might be?

Pretty URLs with Categories and Tags

For instance, if the category is Country (America) and the tag name is city (New York), can I have a permalink like wordpressblog.com/america/new-york for a page that shows all posts belonging to Amercia category and NY tag?
Thanks much! | You could do it manually in your .htaccess although I'm not sure how. In the past I have been able to use partially pretty urls by doing

Force redirect single.php to index
I want to make a force redirect for single.php to index so that it is never reachable by direct access (the site is built in a way that you retrieve all the content on the index page, still need to have this page available though because of an ajax function). I assume this is done in .htaccess?
Edit: I need to be able to access the single.php through an ajax request from the index page, i.e. the redirect should only occur upon direct url access. | put this code in functions.php file
add_action('wp', 'myfun');
function myfun(){
if(is_single()){
wp_redirect( home_url() ); exit;
}

Inserting images in multiple posts native gallery
I am trying to find a solution to a problem that Wordpress seems to lack.
Here is a scenario:
I have uploaded images to a post using the native gallery to display the images. These images then appear under the gallery tab within the upload/insert and they will appear on the post. Works perfectly.
Further down the line I create a new post, I want to include images from my Media Library into the gallery without re-uploading the same images again.
I expected to find, "Insert into gallery", next to "Insert into post", but there doesn't seem to be a way of doing this.
Is there a solution to this? I have done a lot of theme development in the past, but amazed at there isn't a simple solution to this problem.
I would be grateful for any help. | Attachments are a type of post, and a post can only have a single parent, that's why it's not natively possible to have an attachment associated with multiple posts- there is no mechanism for many-to-many associations. There are several ways to solve this, but how simple it is depends on your skill level or willingness to depend on plugins.
For plugins, there's File Gallery, and Advanced Custom Fields, probably others. Otherwise a couple of custom solutions would be to use post meta data to store references to attachments for a post, and/or a taxonomy to "tag" images for each unique gallery you want them associated with along with some meta data for ordering them.

Is it possible to set individual shipping prices in Woocommerce?
I currently have a store running on Bigcommerce, but unfortunately it doesn't offer the functionality that I require. I am debating whether to use a magento/wordpress install or wordpress/woocommerce.
Does anybody out there know if it is possible with woocommerce (or additional plugins) to perform the following:
Set an individual item with a fixed shipping price to different regions/countries.
Offer a free shipping option on orders of a particular item over a given amount.
I believe this would possible with magento, but it appears to be a quite heavy weight option for a wordpress blog/ e-commerce store.
Thanks in advance for any assistance with the above. | Just to help you out ... Wordpress and Magento are comparable as they are both PHP content management systems. However Magento doesn't compare to WooCommerce in the way you mention it above.
For example: you may not need WordPress if you installed Magento. But you have to install WordPress to use WooCommerce.
What you are looking for is Table Rate Shipping this is part of the Magento functions, but you'd need to buy the Table Rate premium extension from WooCommerce to achieve this. | stackexchange-wordpress | {
