Redirecting to new URL structure and 301
I had links like `example.com/?location=boston` on my site. These were indexed by Google. Due to obvious SEO reasons, I had to change the URL structure to `example.com/deals/boston`. The old URLs are there on Google results and redirect correctly to new URL.
What I want to know is: while doing the redirect, is WordPress also doing a 301 header so that Google can update its indexes or there is something that I am supposed to do?
Basically, I want Google to update its indexes i.e. replace `example.com/?location=boston` with `example.com/deals/boston` | Really depends on how your redirects are set up. But you can check the status code using Firebug (or a comparable tool with a request profiler).
Open up the "net" tab in firebug, and hit one of your old URLs. You should** see the request show up at the top of the list, and you'll see the response code in the "status" column. If your redirects are working correctly, the first request will have a status of 301, and will be immediately followed by a second request for your new url, with the status 200.
You coud also do this in Chrome developer tools. The tab you'd use there is titled "Network".
** If your intial request disappears from the list, it probably means that the redirect is being done via JavaScript or some other non-legit method. This method of "redirection" is incapable of returning status codes like 301. | stackexchange-wordpress | {

how can i simple change upload folders to %year%/%month%/%day%?
Is there a easy way to do that? Godaddy have a silly limit of 1024 files in one folder and my client upload more than 500 and with the thumbnails we get lot over the limit.
If im able to changed folders into %year%/%month%/%day% i will be safe about that limit
Also another question is if i can make wordpress to generate thumb only when needed. For example home slider will only use 10 images i dont want the other 1000 images have that thumbnail generated.
Thanks for the help! | The Custom Upload Dir plugin can help with this.

Recent Posts+, how to solve multiwidget?
I have installed the Recent Posts plugin, that came with a widget. Now, i can only add one instance of the widget to the widget areas. I want one instance to show in my widgetarea that only appears on my startpage, and one instance of the widget to my widgetarea that appears on other pages.
Now, the widget doesnt seem to support "multiwidget", but the "widget instances" are supposed to have the exact same configuration. Is there any way to "Force" WP into adding the widget to my other widget area too, even if it means "hacking" the DB? | Easy, Anton!
You don't have to hack the database...
Probably you can find a replacement for this plugin that uses the modern Widgets_API, responsible for the multi-instance widgets. At least as far as I know, because haven't worked much with WordPress pre-2.8.
If you are willing to hack something, hack the plugin using the examples of the Codex.
As for showing one widget in the Front Page and other in the rest, use the plugin Widget Logic. It is very simple and effective. | stackexchange-wordpress | {

How to generate thumbnails when needed only?
I have 1000 images. How can i make wordpress to generate thumb only when needed. For example home slider will only use 10 images i dont want the other 1000 images have that thumbnail generated as its a waste of space and resources.
There is a way to fire add_image_size only when needed ?
Thanks
**UPDATE** As you mention is not really add_image_size what it needs to be fired. What it would be great is to fire the image resize when i use **the_post_thumbnail('slider-thumb');** Maybe this slowdown the first view of the image but that view is usually generated by me when i actually review the post so i dont care.
So between my posts, slider, blog thumbnauls, portfolio thumbnails etc i got 1000 images and i want just 10 images to be resized for the slider i see a lot of wasted resources to generate the thumbnail size for the other 990 images.
Hope its clear now, sorry for my english | ### Take a look at Otto's Dynamic Image Resizer plugin
> This plugin changes the way WordPress creates images to make it generate the images only when they are actually used somewhere, on the fly. Images created thusly will be saved in the normal upload directories, for later fast sending by the webserver. The result is that space is saved (since images are only created when needed), and uploading images is much faster (since it's not generating the images on upload anymore). | stackexchange-wordpress | {

Remove bulk actions based on user role or capabilities

add_filter( 'bulk_actions-' . 'edit-post', '__return_empty_array' );
add_filter( 'bulk_actions-' . 'upload', '__return_empty_array' );

<?php
defined( 'ABSPATH' ) OR exit;
/** Plugin Name: Limit Bulk actions to Editor & Admin */

function wpse_53371_remove_bulk_actions()

{
add_filter( 'bulk_actions-edit-post', '__return_empty_array' );
add_filter( 'bulk_actions-upload', '__return_empty_array' );

automated tests as a user?

Image rotator plugin
I have tried two Rotator plugins so far. Nivo-slider and EasyRotator. Nivo-slider was great, but i could only have an image caption, and i need both image caption and image title. Also, i couldn't get the "bullets" for indicating the current slide to work. So i Googled and found the "EasyRotator"-plugin. Great, except it rescales the images, even if i upload in the correct resolution, the generated HTML is all inline styling so it's kind of hard for me to style it as i want from css.

2. Image Caption
3. Bullets to indicate current slide

Custom taxonomies to define versions of a product
I have a custom post type that describes components of a product. As the product is developed new components are added. I'd like to define what version of the product the component was added, and then be able to browse products by that version.

Is taxonomies that right approach or is there another way to handle this in WP? | Taxonomies is not the right approach here, you should use custom fields (post meta) instead this way you can use `compare` argument of the meta query as `<=` ex:

array(
'key' => '_version',
'value' => '1.0',

Author can only see own post comment and can moderate

if(!current_user_can('edit_others_posts')) {
add_filter('comments_clauses', 'my_plugin_get_comment_list_by_user');
} | The default author role does not have the `moderate_comments` capabilities so you need to add that capability to the author role, so add this to your plugin:
function add_theme_caps() {
$role = get_role( 'author' ); // gets the author role

Does plugin's uninstall.php file have access to the plugin 's object?
I read on the codex that the best way to implement a clean uninstallation functionality to a plugin is by adding a uninstall.php file inside your plugin directory.

delete_option('my_plugin_options');

$wpdb->query("DROP TABLE `$table_name`");

As per my tests, the table remains after deletion, so i guess i'l fallback to using a hook inside my plugin's file, unless i'm missing something? | I'm not in my desktop, but I suspect it won't be retrieved.
But:
* have you tested it? Does the table gets droped?
* I'd say you need to declare _global $wpdb;_ , isn't it?
* if you don't have any, a tool like FirePHP is **really** handy when developing
* anyway, this seems a case where is pretty harmless to hardcode the table name | stackexchange-wordpress | {

How to display user role

Getting Thumbnail in fetch_feed from custom field

$rss = fetch_feed('rss link here');
$maxitems = $rss->get_item_quantity(5);

$item->get_description();
$item->get_permalink();
$item->get_title();
get_date('j F Y | g:i a');
But i am not sure how to get thumbnail in my feed or here in this system. But in my posts i do have a custom field called post-img for displaying posts.
Help is appreciated. Thanks | According to the Codex, fetch_feed() uses the SimplePie engine for parsing RSS.
So, if `$item->get_title();` is working, then you should be able to do:
> `$item->get_thumbnail();`
as per the SimplePie documentation, as long as there are any thumbnails already on the feed.

Before running the above, you have to insert the images on your feed. Check for _display featured image in RSS feed_ and _How to grab first image attached to post and display in RSS feed?_ topics on it. | stackexchange-wordpress | {

//mail should go.
}
else{
//stop the mail.

Wordpress redirect on login
I have downloaded my site to a production environment. I have set up both the live site and the production site to use the same DB. When i login to the admin panel i get redirected to the live site. I know that wordpress stores URLs in the DB so i want to modify (hard code) my production site not to redirect anywhere.
Where and how?
Edit: I found the solution to this particular problem here <
But when one problem was tackled two new ones appeared and as discussed below, it's not worth it. | I think getting the site to redirect to the proper location on login would only be the beginning of your issues with this setup.
What would happen when you want to use any WordPress function to retrieve the site url? You would possibly have to re-write those functions as well, so that they return the production url instead of the url from the database.
If your production site is on your local machine you might try editing your HOSTS file so that your local machine thinks that its the real server. When you are finished working on your local machine you could then switch your hosts file back to normal to see the real live site again.

Password in wp-config. Dangerous?
I don't know a lot of Wordpress yet, and I'm just wondering:
Before installation you have to fill in the correct data in `wp-config-sample.php` but this also includes the database password. Isn't that dangerous? I mean, can some one explain how this is protected from just reading the file and thus getting the password of your DB? | The "Hardening WordPress" page of the Codex contains a section on "Securing wp-config.php". It includes changing the permissions to 440 or 400. You can also move the wp-config file one directory up from the root if your server configuration allows for that.
Of course there is some danger to having a file with the password like this if someone gets access to your server, but, honestly, at that point they already are in your server.
Finally, you don't have much of a choice. I've never seen an alternate means of configuring WordPress. You can lock it down as much as you can, but this is how WordPress is built, and if it were a **serious** security threat, they wouldn't do it that way. | stackexchange-wordpress | {

Putting footer content in a "page" - Doing it wrong?
So, in my shortish WordPress development career, I've gotten in the habit of creating a "page" for the content in a footer, and adding different fields with the wpalchemy class. Everything with this approach seems to work fine, except for the fact that users can go to mysite.com/footer and see something I do not want them to see.
Should I somehow force this url to 404? or is there something fundamentally wrong with my approach? | I don't think there's anything fundamentally wrong with your approach, I see it pretty often.
You could hook `parse_request` and 301 redirect any requests to footer to the front page. I wonder though how visitors would end up there in the first place, as long as you exclude it from the sitemap and don't link to it anywhere.
Or you could create a custom post type for this kind of content and make it not publicly query-able. | stackexchange-wordpress | {

Styling Previous/Next Pages differently from Index
A friend of mine pointed me towards using child elements to style my index page so that I could have one loop and several different visual styles (a featured post, a smaller sub-featured post, and several smaller thumbnails). This is very helpful in that I can add posts and the existing posts will just flow through this styling.
For example, I can style the .hentry class by:
.hentry:nth-child(3)
{
background-color:#00000;
}
And so on.
The problem I run into is when clicking on the next/previous links on the bottom of the content portion, those following pages maintain that styling. Is there a way I can style those pages differently?

Where is phpMyAdmin inside WordPress?

Remove field in the form : only works for "url", not for "email"?

{
if(isset($fields['email']))
unset($fields['email']);
return $fields;
}
One reason that it could be failing on your theme is that args were passed into `comment_form`. Specifically, the theme author passed in a `fields` key into the `$args`.
As the filter name (`comment_form_default_fields`) implies, the fields are only defaults.
Fortunately there is another filter! `comment_form_field_{$name}`. Just hook in and return false and it should get rid of the email field.

Sharing a custom taxonomy - No posts?

'sort' => true,

Friendica integration using wordpress authentication

In a nutshell if hook can pass N arguments, your options are:
* pass 1 argument (default)
* pass <=N arguments by specifying number
* do not pass any arguments by specifying 0 (rare, but highly useful at times)
Note that you cannot change order of arguments passed, if you need Nth you will need to pass as many and then ignore unwanted ones in your function (which only makes sense in few hooks, because first argument tends to be meaningful one, rarely second). | stackexchange-wordpress | {

making sense of admin-ajax
So I'm working with ThemeTrust's "reveal" theme, and there is an ajaxed in chunk-of-content that I'm really trying to change (grab custom meta fields (images) + insert into a slideshow).

jQuery("#projectHolder").load(
MyAjax.ajaxurl,
{
action : 'myajax-submit',
slug : projectSlug
},
function( response ) {
}
);

changed custom post type now $image_attributes[0]; broken
i wanted to change the slug of a custom post type
so i
renamed

changed
$the_query = new WP_Query(array('post_type'=>'myslug','posts_per_page'=>8));

certain images show

some have images some dont.

Multiple post type queries (with specific arguments for each)

'posts_per_page' => '20',

query_posts( $args );

the_title();

How does Wordpress handle sessions?

Code to make a post sticky
How is it possible to upgrade a post to make it sticky directly from code, not by admin area? Is it possible through a code like:
update_post_meta($post_id, $meta_key, $meta_value, $prev_value);
In this case, the $post_id is known, but the $meta_key?
Thank you in advance for your answers | The sticky posts are saved as an array of post IDs in the _wp_options_ table. Hence,
$stickies = get_option( 'sticky_posts' );
$stickies[] = $post_id;
update_option( 'sticky_posts', $stickies );
will make the post in question sticky.
**EDIT:**
Even better, the core provides functions to stick and unstick posts (had to have 'em).

unstick_post( $post_id );

if ( $settpdf ) update_post_meta( $post_id,'_pdf_id', $attach_id );
return $attach_id;

Is there any way to dynamically alter widget titles?
I have a case where that are a lot of widgets in several custom sidebars. I am wondering if there is a simple way to alter the titles of each widget dynamically. Typically a widget has a title field you can set manually or on the plugin itself.
I wish to add something like a meta field value per post to each widget title.
The logic would be something like:
$dynamic_title = get_the_title();
// add a filter to change the widget titles per post value
//
// The widget title would be something like "Recent Posts for $dynamic_title"
I know there is a `widget_title` filter but how do you target specific widgets?
ps. I cannot use the regular `register_sidebar` parameters due to having many widgets needing specific titles. | You can use the `widget_display_callback` (fired, predictably, just prior to displaying a widget :) ).
add_filter('widget_display_callback','wptuts54095_widget_custom_title',10,3);

if ( is_single() ){
//On a single post.
$title = get_the_title();
$instance['title'] = $instance['title'].' '.$title;
}
return $instance;
}

Add mass action to wp-admin/users.php

Let's say i select 5 users and i want to asign them some user_meta value. | Unfortunately this isn't possible. Custom actions cannot be added to the bulk actions dropdown (see trac tickets: < and <
For posts you can use the `restrict_manage_posts` hook to create another drop-down / add buttons to trigger your custom action. But there is no `restrict_manage_*` hook available for the user table.
So the only (and not particularly pretty) workaround is to use javascript to insert extra options into the drop-down menu.
However, there is no (supported) way of handling the action - so this would also have to be handled yourself by hooking into the `load-*` or `admin_action_*` hook. (See the core files here).
You would then need to check the posted data (the user IDs, the action identifier, nonce, etc) inside that hook and then you would need to check the nonce and the current user's capability to perform that action.

In general, how do I use styles differentiated by template instead of using a global setting like the one above? | Create a primary stylesheet and enqueue as normal. Then, make a series of conditional statements using WP core functions - `is_home()`, `is_404()`, `is_page_template('template.php')` and so on. In each of those conditionals, enqueue the stylesheet you want that overwrites your core stylesheet, using your primary (`style.css`) stylesheet as a dependency.
Untested code, but should work:
function my_styles() {
wp_deregister_style( 'header' );
wp_register_style( 'style', get_template_directory_uri() . '/css/style.css' );
wp_enqueue_style( 'style' );
if (is_home()) { wp_enqueue_style('homestyle', get_template_directory_uri(). '/css/homestyle.css', 'style'); }

How do i 'deactivate' a plugin only on a certain page template?
I have a plugin which is great but it's kind of aggressive, and it changes a lot more than it should (but there are no settings to fix this).
I have a custom page template that calls wp_head('less') ... header-less.php, and i have an equivalent for footer-less.php.
I basically want, in this custom header-less.php to DE-REGISTER the plugin immediately after it gets registered.
note that i dont want to DeACTIVATE the plugin, because i really need the functionality on the other page templates, only on this certain template do I want to basically 'destroy' the plugin or deactivate it somehow | A quick glance at that plugin shows that it loads the filters from an option, `trueedit_options`. You might be able to add a filter to `option_trueedit_options` and check the context of when that option is being loaded and return an empty array. It runs on `init` though, so not sure how you'd determine that.
Another option is to add the filters back on in your header file. If you look in `/wp-includes/default-filters.php` you'll see all of the filters that are added to the content which could potentially be removed by the plugin:
add_filter( 'the_content', 'wptexturize' );
add_filter( 'the_content', 'convert_smilies' );
add_filter( 'the_content', 'convert_chars' );
add_filter( 'the_content', 'wpautop' );

What is the most efficient method for loading widgets in functions.php
I have seen WordPress developers use two different methods for loading custom widgets from the functions.php file.
The first:
include("functions/my-custom-widget.php");
The second:
require_once(dirname(__FILE__) . "/functions/my-custom-widget.php");
Which one of these methods is more efficient. I'm particularly interested in performance if there is a difference at all. Does the require_once follow better 'best practices' ?
I'm sure there are plenty of other ways of doing this. If anyone has a better recommendation I would love to hear it.
Thanks. | Both are acceptable but not recommended. Use `locate_template()` instead because a child theme can overwrite the loaded file then.
Example:
$found = locate_template( 'functions/my-custom-widget.php', TRUE, TRUE );
The first `TRUE` tells WordPress not only to _search_ for the file but to _load_ it actually. The second makes it a `require_once` call.
The function return the path to the located file in case you need it later. If nothing is found it returns an empty string. | stackexchange-wordpress | {

Display Notification Bar on Header on Certain Post Count
I want to display notification bar on header in my Wordpress theme when user submit certain number of post. I want to notify my author once they are submit amount of post. e.g.
if (authorpost === 50){
// congratulations! you have submitted total 50 posts bla bla.
} else if (authorpost === 100) {
// congratulations! you have submitted total 100 posts bla bla.
} else { // nothing will display }
I want this into header.php and will place my div right after tag. Also I want to display only when they submit certain number of post as I mention above as soon as they cross that number it won't display anything. | A simple way to achieve this would be to do something like the following;
<?php
$user_id = get_current_user_id();
$post_count = count_user_posts($user_id);
if ($post_count >= 50 && $post_count < 100) {
// Congratulations you have submitted 50 posts!
} elseif ($post_count >= 100) {
// etc etc...
} else {
// do something else, or nothing.
}
?>
You can place this within your header.php file, or for that matter in any template file should you choose to display this information elsewhere as this can run from out-side of your post loop.

How to make media upload private?

How to Protect Uploads, if User is not Logged In?
_Frank Bueltge's_ answer seems interesting but the code is quite complex. As he himself admits his english is nasty, but I can assure his coding skills are superb :)
And the answer provided by _hakre_ could be operational:
* Protecting one or more folders inside `/wp-content/uploads/` through `.htaccess` as detailed there.
* Moving the desired files to this upload folders according to User or Post-ID, and for that the answer I provide to this question should do it. And, with the examples provided, maybe you can think of other kind of filtering. | stackexchange-wordpress | {

Single database for multiple instances
I would like to create two instances of WP on a single domain. For example, I would like wp1.domain.com and wp2.domain.com to use a single database (same comments/posts). One for production and one for development. Is this possible, and if so, how? | It's considered best practice to have two separate databases (one for production, one for development) then migrate the database as detailed here. If you, for example, install a database-changing plugin on one but not the other, you risk breaking one of your sites until you duplicate those changes over. If you're working late tweaking code, you might end up breaking your live site and not realizing it until the angry client calls to rip you a new one.
Really, keep your production and development sites completely separate. It will save you a number of hassles down the road.
If you only have access to a single database, set each site to use a different database prefix. This ensures easy duplication with standard SQL tools while keeping separate dev/prod environments. | stackexchange-wordpress | {

Should I remove_filter in order to replace a filter?
If a plugin modified one of wp's filters by "add_filter", and I want to discard the modification and modify the wp's filter by my own codes. Should I remove the plugin's filter before I add my own filter? | Yes, you need to remove it first and then add your one. You can do it by calling remove_filter function like this:
remove_filter( 'wp_core_filter_hook', 'wp_core_filter_hook_handler', 10 );
Pay attention at third parameter passed to function: it is priority, it should be the same as defined when the function was originally hooked, otherwise the filter hook won't be removed.
If you want to remove all hook handlers, you can call remove_all_filters function:
remove_all_filter( 'wp_core_filter_hook' );
// or with priority
remove_all_filter( 'wp_core_filter_hook', 10 );
This function takes two parameters: filter name and priority (optional). If you pass priority then all handlers with specified priority will be removed.
And finally if you want to check if any filter has been registered for a hook, use function has_filter. It takes two parameters: filter name and function name (optional). | stackexchange-wordpress | {

How to change "Draft" string for status of custom post type to "Unavailable"?
**ANSWER MOD** : just an important mod to the chosen answer:
// check if you actually have drafts; also avoids extra '|' separator
if (isset($views['draft'])) {
// 'Drafts' should be added (and come first) if you don't want to end up with 'Unavailables'
$views['draft'] = str_replace(array('Drafts','Draft'), 'Unavailable', $views['draft']);
}
and the mentioned caveat is not showing up for me on 3.4. :D
* * *
Only for one particular custom post type `employee`, I want to change the name/string "Draft" (which stands for the `'draft'` status) to "Unavailable" for any `employee` post that has a `'draft'` status, anywhere the name shows up on the admin screens and basically throughout the entire site, i.e.
!enter image description here
Is there a hook for this? Or is there a better way to do this? | I was investigating the issue for this question, and one option is using the plugin Edit Flow.
It can be configured to display custom `post_status` in specific CPT's, but further tests are necessary to see if it applies to this case.
* * *
Other option is using toscho's Retranslate plugin, where you can define the string to be translated and the `post_type`: <
It gets almost all the job done, because, curiously, there's one string (the very first one of the screenshot) that don't gets translated and one extra code is necessary:
add_filter( 'views_edit-employee', 'wpse_54330_custom_draft_translation', 10, 1);
function wpse_54330_custom_draft_translation( $views )
{
$views['draft'] = str_replace('Draft', 'Unavailable', $views['draft']);
return $views;
}
One caveat of this method is that just after "quick editing" the post status, the word _Draft_ appears... | stackexchange-wordpress | {

Restored Wordpress on new Server - Can't auto-update plugins
I have installed a new Ubuntu server and have set everything up for Wordpress. I have also extracted mySite directory in the /var/www/ and did a `mysql -u mysqlusername -p databasename < blog.bak.sql` to restore the data to the database.
It all worked smooth and works beautifully.
The only problem I have discovered is when I try to auto-update the plugins.
Please click to see the screenshot (I don't have enough reputation to insert a screenshot here) <
Well, I have never setup any FTP on my previous server. How comes this is now asking me this information? And yes I was able to auto-update plugs on my other server without a problem.

How to edit/delete single row items in a table on my own menu page
I have successfully created a wp-LINKS-list-table that displays the output of WP's core "Links" table in the WP Dashboard, and I have it displaying on a menu page I created. Step 1 accomplished!
But now I would like to be able to have the single row edit/delete (database) functionality just like the Links page. Right now I can edit/delete the links, but it's just adding/removing items from the actual links database table. I'm assuming that I not only have to create a different database table for my own queries, but I need to process my pages outside of the WordPress core as well. Right?
Or is there a core WP functionality that I can use to edit/delete my own table items? | Wordpress allows you to use a class called wpdb
Here is an example of how you would use it
function add_to_db() {
global $wpdb;
$your_table_name = $wpdb->prefix . "wp-LINKS-list-table";
$the_value = '123';
$wpdb->insert( $your_table_name, array('column_name' => $the_value,));
this will insert 123 into the column_name. You can read more here
Note: If you are creating a menu page that reflects the tables similar to the wordpress tables there is another class you can use to help you. It is called WP_List_Table I would suggest reading that and getting the Custom List Table Example Plugin it is very helpful showing examples of using WP_List_Table. | stackexchange-wordpress | {

How can I stop TinyMCE from converting my HTML entities to characters?
Here's the problem: I paste the HTML entity code for, let's say, a service mark (`℠`) into the HTML view of the editor. As soon as I switch to the "visual" tab, my entity code is turned into an _actual service mark character_ (I guess the corresponding UTF-8 character or something? I don't know from character encodings...). I don't want this--I want it to stay as the entity reference.
Is there some kind of configuration I can change to stop TinyMCE from doing this? My understanding from reading the internets is that this is not the default behavior--that TinyMCE should actually be doing the opposite, and converting characters to their entities. So is this something specific to WordPress' version of TinyMCE? | According to this page, you can use the `tiny_mce_before_init` filter, make sure the entity encoding is set to `named`, and then add whichever special characters you want to the entities array. | stackexchange-wordpress | {

Disable pingbacks and trackbacks in blog posts
