On Plugin Activation, How Do I Check for Proper Transport Mechanism?
For a plugin that communicates with somewhere else, I hear we're supposed to use wp_remote_post and wp_remote_get instead of PHP's Curl library.
Okay, but is there a fast and proper way on plugin execution to test for a blog's PHP/host OS to have the proper transport mechanism installed? I mean, I could attempt a test POST, but thought WP might have a better, faster mechanism that I can test for? Doing the following is unacceptable:
if (!function_exists('curl_exec')) {
wp_die('The CURL API is not installed with PHP. You cannot use this plugin without that. Ask your web hosting provider to install it.');
} | I wouldn't cause the plugin to die like that. Just check for cURL each time you need to make a call or fall back on `wp_remote_(post|get)` (eg. write a wrapper function that takes care of the check and send the data/headers you want).
BUT, if you really really want to disable the plugin if cURL is not installed, you can use an activation hook to check for the `curl_exec` function and deactivate the plugin if not.
<?php
register_activation_hook(__FILE__, 'wpse51312_activation');
function wpse51312_activation()
{
if(!function_exists('curl_exec'))
{
// Deactivate the plugin
deactivate_plugins(__FILE__);
// Show the error page, Maybe this shouldn't happen?
wp_die(
__('You must enable cURL support to use INSERT PLUGIN NAME'),
__('Error')
);
}
}
For what it's worth, I believe that the HTTP api tries to use cURL if it's available. | stackexchange-wordpress | {

Getting the action's tag name within the action
There's a function attached to a set of actions, like this:
add_action('some_tag', 'the_function');
function the_function($maybe_some_vars){
// ...
}
Is it possible to find out the action name ("some_tag") within the_function?
The reason I'm asking, is that I'm attaching the function to multiple actions (some of them custom, some belong to WP like `the_content`). The code that executes within the function depends on knowing the name of the action.
I did manage to get it using `debug_backtrace()`, but I'm pretty sure that's not a very reliable way. | Simple: `current_filter();` (link to plugin.php) or `global $wp_current_filter;`. | stackexchange-wordpress | {

Create WordPress taxonomies based on theme settings
Is it possible to create taxonomies based on theme settings? That is, are theme settings actions run before taxonomies / post types are initialized? | Yes. Post types and taxonomies are (should be) registered on the `init` hook. You are able to use `get_option` inside that hook to retrieve your theme's settings and register your post type/taxonomy with args based on those settings.

How can I detect if a user changes their password?
I would like to track when a user changes their password. Is there a way to detect when a password has been changed? | WordPress sends an email to the admin's email when a user resets their password.
To get a notification when a user changes their password you could hook into the `profile_update` action which is fired when a user's profile is updated.
When the action is fired WordPress has already validated and updated the user's details we only need to check if the user submitted a password with the request, if it was submitted then the user's password has changed.
function my_profile_update( $user_id ) {
if ( ! isset( $_POST['pass1'] ) || '' == $_POST['pass1'] ) {
return;
}
// password changed...

How do I add a promotional message to my posts?
I'm sure this is a dup, but I honestly can't find an answer.
I'd like to add a message to the start and end of my posts:
"Check out my new startup: Facebook For Dogs!"
Is there a simple way to do this, hopefully using a plugin? | You'll want to hook into `the_content` to add a message.
Something like this:
<?php
add_filter('the_content', 'wpse51338_filter_content');
/*
* Filter the content to add a message before and after it.
*/
function wpse51338_filter_content($content)
{
// not a singular post? just return the content
if(!is_singular())
return $content;
$msg = sprintf(
'<p class="special-message">%s</p>',
__('Here is an awesome message!', 'your_textdomain_string') // this is your message
);
return $msg . $content . $msg;

Listing all posts from current category on page
I'm trying to list all posts from a certain category, in a list, on the category page that already lists the posts out in blog form. I'm trying to do it in the header area so that you can get an overall look at the posts on the page. I found this:
<ul>
<?php
global $post;
$category = get_the_category($post->ID);
$category = $category[0]->cat_ID;
$myposts = get_posts(array('numberposts' => 5, 'category__in' => array($category), 'post__not_in' => array($post->ID),'post_status'=>'publish'));
foreach($myposts as $post) :
setup_postdata($post);
?>
<li>
<a href="<?php the_permalink(); ?>">
<?php the_title(); ?></a>
</li>
<?php endforeach; ?>
<?php wp_reset_query(); ?>
</ul>
But it always seems to cut one of the posts out of the list. Is there an easier way to do this, without a plugin?
Thanks | Good news! I think you're making things harder for yourself than they need to be. If I understand your question, you're looking for `rewind_posts()`. The always useful _Digging Into WordPress_ has a nice summary of it.
Because both tasks involve looping through the _same query_ , you don't need `get_posts()` at all.
Instead, you'll want to use the aforementioned `rewind_posts()` something like this:

Prevent empty Post Title on form submit via front end post (wp_insert_post_)

How to encode post content as JSON?
I`m trying to construct a json object but are having difficulties with the_content since it returns newlines, which causes the script to fail. The error messages received is: **Uncaught SyntaxError: Unexpected token ILLEGAL**
**Example of the json:**
[ {image : ' title: 'Example string
with newlines
that outputs illegally!'}]
Ideally I'd want it to output the HTML content (as seen when pressing the HTML tab in the editor). | To output JSON always the function `json_encode( $string )`. The function is not available on all hosts. Don't worry, WordPress offers a fallback in `wp-includes/compat.php`. That's a wrapper for `class Services_JSON::encodeUnsafe()` (see `wp-includes/class-json.php`).
If you take a look at the source you'll see: It's not a trivial job to encode a string. :)
There is a small difference: The native PHP `json_encode()` accepts a second parameter `$options` since PHP 5.3.0. The WordPress fallback doesn't.
New lines are encoded as `'\n'` in JSON; you cannot get the same output as in the HTML tab in TinyMCE.

How to tell WordPress that jQuery exists on the page to avoid duplicates via wp_enqueue_scripts
To reduce http requests, I'm combining all scripts that my theme uses into a single minified .js file each time theme options is saved.
One of the files in this .js is the jQuery library.
Rather than including jQuery as a separate file (using wp_enqueue_scripts), I'm including the wordpress core jquery file as part of the output stream of this master .js file
The problem is that since I'm not using wp_enqueue_scripts() to load jQuery, there's is a possibility it can be included more than once on the page via a plugin that does not know its already there.
Can I set a flag so that WordPress knows that file already exists on the page? | You really shouldn't do it, it's not a good practice. You should always use the jQuery version supplied with WordPress package. If you use your own jQuery version in your own file you would have to update it manually every time the jQuery gets updated in WordPress package.
If you really insist on doing that, the most simple, hackish solution I can think of is to first deregister the original jQuery, then register your file (minified.js) as jQuery. You will surely run into problems of incompatibility with plugins sooner or later. | stackexchange-wordpress | {

Validate data on attachment_fields_to_save
I'm very glad that there is such a dedicated website for WP.

I can check and so on, BUT THE QUESTION IS: How to validate these fields, so if validation do not pas - WP returns an error in it's regular style, just like in registration form if you fill bad email.
In registration process in `register_post` action you can do this `$errors->add('some_error_code', "<strong>Klaida</strong>: Nenurodėte įmonės kodo");` and it will not save data and return to visitor an error. I want that in saving attachment form :D | # THE ANSWER
Well as it happens many times in my life - i found the answer myself. For people who struggles as me here the answer:
`$post['errors']['field_name']['errors'][] = __('Error text here.');`

Is there any more DB efficient way of doing this, kind of like a have_posts( 'post_type=vacancy' ) ? | I wouldn't worry about doing a second query (e.g. using `get_posts()`). If you want to check if a post type has any published posts - you're going to have to query the database.

Add Class to Specific Paragraph of the_content()
Let's say I want to give the first paragraph bold text by adding a body class to the first paragraph. Is there a way to filter the output of
the_content();
or any other paragraph? First paragraph? Last paragraph?
I know I can do this using Javascript or CSS (:firstchild), but is there a native WordPress way?
Thanks.
J | The following bit of code adds a class to the first paragraph output by `the_content`:
function first_paragraph($content){
return preg_replace('/<p([^>]+)?>/', '<p$1 class="intro">', $content, 1);
}
add_filter('the_content', 'first_paragraph');
Add the above to your theme's functions.php file.
Then in your CSS add something like:
p.intro { font-weight:bold; }
I can't claim credit for this solution (see this thread in the WP forums) but I tested it and it worked great for me in WordPress 3.3.2. You should be able to modify it as needed to target whichever paragraph your heart desires. | stackexchange-wordpress | {

uploaded images not going to /uploads folder
having a huge problem with a site. i updated the theme to use post thumbnails (that's how old it is) and then when trying to upload an image to use as featured thumbnail: the images process/crunch but then the URLs result in 404s.
!enter image description here
there isn't anything abnormal in the site's .htaccess. there actually wasn't a wp-content/uploads directory so i made one and the chmod permissions are 0755, so that shouldn't be the issue. i reset the media settings folder to be the default but no images are ending up in that folder.
edit: changing the uploads folder to 0777 permissions seems to resolve this. is it safe to leave the permissions this way? | If I remember it right, this happened to me once. I deleted my `/uploads` directory (to delete all the images) and went back to posting thinking that WordPress will automatically create an `/uploads` directory and any necessary sub-directories for me.
And yes, that's how it works. But here's the catch -- WordPress doesn't set proper permissions for the `/uploads` directory and the directories within, this time. The new chmod permissions were like `0700`.
**SOLUTION:** What I did was, I set back the permissions for `/uploads` directory at `0755`, and selected the option in my FTP client to set the permission recursively to all sub-directories in the `/uploads` directory.

Compare the_excerpt() to the_content()
Is there a way to compare the_excerpt() to the_content() to know if the_excerpt() is actually showing the entire post content? for instance, if a post were particularly short.
ultimately i'd like to have a "Read more" link at the end of excerpts. but i want it to say 1 thing for posts and another for posts of the video format (ie... 'watch the video' instead of 'read the rest'). but at the same time i don't want to manually tack this on after the excerpt, but i have plenty of posts that are short enough they don't need a 'read more' link, since the_excerpt displays the full post.
but adding the permalink to the excerpt_more filter isn't quite right since it won't add a link to the video posts that have no other content.
so i'm stuck between the two. i hope that made sense. if it didn't it's late and i will try to re-explain in the morning. | What you're trying to do with the video is exactly what Post Formats were created to handle.

Secure Validation of wp_editor in Theme Options
So I just found this great WPSE thread about security for themes/plugins. It answered most of my questions but it was created before the new `wp_editor()` function was built.
I have two TinyMCE editors on my Theme Options and I'm wondering whether I need to use `esc_html()` or `esc_textarea()` in a validation callback before saving the theme option. It seems to me that TinyMCE takes care of a lot of that stuff (as well as the Settings API security that's taken care of), but there's still not a lot of documentation out there about `wp_editor()`.
Any resources and answers appreciated. | `esc_html()` and `esc_textarea()` are, appropriate to their names, escaping functions and really meant for display rather than sanitizing or validating. I would use `wp_kses()` or `wp_kses_post()` (which is just `wp_kses()` with the global `$allowedposttags`) to sanitize input from a `wp_editor()` field before saving. | stackexchange-wordpress | {

Will it break my site if I delete all transient records in wp_options table?
My site currently has an outrageous 500k+ transient records in the wp_options table. This causes the table to be crashed frequently and so be my site.

New rewrite rules for custom taxonomy and reuse default

i.e. WordPress already directs example.com/?location=national and example.com/?location=boston correctly. I want to add new rules on top of these and want to reuse them.
Is it possible? | Note that the url-rewriting doesn't directly determine the template used. A pretty url is interpreted as a query and then that query determines what template is used based on the template hierarchy.
So only need _one_ rule:
example.com/localdeals/myterm => example.com/?location=myterm
WordPress will look for the template `taxonomy-location-myterm.php` and use that (if it exists) or otherwise fallback to `taxonomy-location.php`
To add the above rule, when you register your taxonomy:
register_taxonomy('location','post',array(
'hierarchical' => false,
...
'query_var' => true,
'rewrite' => array( 'slug' => 'localdeals' ),
...
));

</div>
where $variable is the data of the attached image/s.

[0] => url
[1] => width
[2] => height

}

How Can I Centralize Content Usage and Approval in a WordPress Multi-Site installation

* options to create a link to those blogs, which means when the original post is changed, other copies are changed, too

Removing widget without using unregister_widget

Use Firebug for Firefox, or Chrome/Safari inspector to discover the widget ID.

How to programatically set the post title of a CPT on wp-admin
I've been playing with custom post types & custom fields, using a combination of the `types` plugin and the `advanced custom fields` plugin, also having done the same manually.
Occasionally I want to create a CPT where a `title` would be inappropriate - for example, an FAQ where I want two fields labelled `Question` and `Answer`. This does work without a title, however they all get saved as `(No Title)`.
What I'd like to do is either set the `title` to the value of the `Question` custom field, or somehow define my own `title` field that I can label as I like.

add_filter('enter_title_here','wpse51871_alter_title_label',10,2);

Hook for feed creation?

Also, how would I get the `args` in the URL into my function as an array? | It depends what you want to do as for when you want to hook into the process. `the_content_feed` is fired for each item in your feed, so this probably isn't the one you are after.
You could use `pre_get_posts` which fires just before WordPress queries the database:
add_action('pre_get_posts', 'catch_the_feed');
function catch_the_feed($query){
if($query->is_main_query() && $query->is_feed()){
//It's a feed!
$variables = $query->query_vars;
}
}
_untested_ but `$variables` should be an array of registered query varibles and their value (usually populated from what was recieved in the url).
...or you could use `template_redirect` which is when WordPress has retrieved the posts and is ready to display them (or redirect the user to a feed template) | stackexchange-wordpress | {

Using WP Multisite for multi language site? A good option?
I´m going to develop a site for a client which requires multiple languages. I have no experience with this from beforehand so I´m researching what might be the best way to do this.
The webpage will be in swedish, english and norwegian. I must have the ability to have separate content in each language, like separate news posts for each language, or separate products etc.
Would using WP multisite be a good way to achieve this? I´m thinking I can do like this: Start a network with three sites: www.domain.se /en and /no. Develop for the first language version (swedish) and fill it with the correct content. Export the content, and import it from the other installations. Then replace the contents with the same content in the other languages.
Would this be a good way to achieve what I want, or would you suggest some other way?

Disable the post save process completely
I need a way to disable the save process completely using an `action/filter`. Something that works (for e.g.:) in the `query`, `posts_clauses` or `wp_insert_post/save_post/update_post` hooks.
So far I only tried to `return '';`, which gives me tons of errors for missing values for post object parts in the admin UI.
This should happen "silently", so no errors get thrown when `php_error/WP_DEBUG` and such are set to `TRUE/On`.

Is It A Good Idea To Change Author Slug (user_nicename field) Directly In MySQL DB?
Searching for a how-to on changing author slug, I found two methods:
1. Change the `user_nicename` field in the MySQL database of your WordPress site to whatever you want the slug to be.
2. Changing the Author Slug from Username to Nickname
The (2) is out of question because I want the slug to be something custom, but not the nickname/nicename.
As for (1) I wanted to know if this is okay -- to change the value of `user_nicename` field in the database for the user? | Providing you know what you're doing that shouldn't be a problem. You will however have to check that any author/user pages you may have are linked by id rather than name in the code:
$data = get_userdata( $userid );
As opposed to
$data = get_userdata('Admin');
Because the ID will never change (unless you delete the row and re-insert) but if you change `Admin` to `Supreme Overlord, Master of this Domain` the second reference will not work but the first will.
NOTE, this will not break the usage of `current_user_can($capability)` but will break `user_can('Admin',$capability)` but I don't see why you would be using `user_can()` over `current_user_can()` anyways. | stackexchange-wordpress | {

Recently I changed the url of my site from atlas.site.com to site.com, one thing I just came across in the admin area for posts, custom post types, pages, where there are more than one page of posts, the arrows for next, previous, first & last page, are all pointing at atlas.site.com/wp-admin/...
I've done a find and replace for atlas in the db, but perhaps I'm not looking in the right place, and it returned 0 results, and WP_SITEURL & WP_HOME in wp-config are both set to <
The same applies for Title, Author, Date at the top of the columns for sorting.
Thanks | Ok so apparently this site is behind a firewall or proxy.
On lines 491 and 658 in wp-admin/includes/class-wp-list-table.php, replace this line `$current_url = ( is_ssl() ? ' : ' ) . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];`
with
`if(!empty($_SERVER['HTTP_X_FORWARDED_HOST'])){ $hostname = $_SERVER['HTTP_X_FORWARDED_HOST']; } else { $hostname = $_SERVER['HTTP_HOST']; } $current_url = ( is_ssl() ? ' : ' ) . $hostname . $_SERVER['REQUEST_URI'];`
Thanks goes to < for posting this fix.
Now the question is there any way to do this without editing core files? If anyone can post that I'll mark that as the accepted answer, I haven't had to modify my core yet, and I'd prefer to keep it that way. | stackexchange-wordpress | {

Media Library, hook on delete user action
I need to run my function when a user deletes a media file from the media library. Is there a hook I can use?
Would appreciate it if someone could please point me to the right direction.
Thanks! | A more appropriate hook may be `delete_attachment($post_id)`. You may also need to hook `edit_attachment`. Note that the `post_id` is that of the attachment type post, not the page/blog post to which the media is attached (if any).
In case you want to know when media is added, hook `add_attachment($post_id)`. Note that `add_attachment` is called before intermediate size files are generated but after the media has been placed in the upload directory. | stackexchange-wordpress | {

Is there any way to add that posts into my custom menu I created in Appearance->Menus?

Using the_excerpt() on a page
I've been trying to utilize the PHP excerpt function to call from her recent blog post to post on a main landing page without avail. Any thoughts?
<div id="home_news" class="prefix_9 grid_3">
<div id="newsbox" style="display: block;">
<div id="news">
<h2>Welcome</h2>
<div id="news_content">Welcome to the... .check back shortly for a new selection of oil paintings, latest prints and greeting cards</a>.
<?php
$my_query = new WP_Query('category_name=blog&posts_per_page=1');
while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->505;
the_excerpt();
endwhile; ?>
</div>
</div>
</div>
</div> | While this was far from clear in the OP at first, I think this might be a good solution. Just make a shortcode to place the excerpt in the body. (This is a bad idea if you want this on _every page_. This is a good idea if you want it once in a while on some pages in the body.)
Here's code to put in your functions.php:
function the_excerpt_shortcode() {
return get_the_excerpt();
}
add_shortcode( 'the_excerpt', 'the_excerpt_shortcode' );
Once you have the, just put this in your page body:
[the_excerpt]
And you're good to go.
If you're using Twenty Ten, Twenty Eleven, or some other theme that hooks to the excerpt_more filter, you may have to modify that short code to strip an auto-generated "Continue Reading..." link, but for many themes that's unnecessary. Consider this a starting point. | stackexchange-wordpress | {

WordPress network: set themes and plugins for new blog
How can I enable specific themes and plugins for new blogs that have been created with `wpmu_create_blog`? I'd like to set the themes and plugins in code rather than having a person manually set them in the network administration section (i.e. not in `
Thanks!
Update: Actually I think I may have figured **part** of this out. `wpmu_create_blog` has a `$meta` property. This property can be set to an associative array with a key of 'allowedthemes'. That key's value should be set to an associative array with keys:values = 'theme-name-or-id':true. I still need to set the starting theme for this blog and set plugins, which must be similar. Is this even a good approach? | This WPSE answer led me to the $meta argument for `wpmu_create_blog`. That led me to this Support thread showing that $meta can include `template` and `stylesheet` arguments which seem to contain the folder name for the theme you want (just like the "Template" field in a child theme's style.css head section).
I'm having a hard time finding good documentation on `wpmu_create_blog`, but hopefully this is enough to work on. | stackexchange-wordpress | {

Localized Date Format for Custom Field
I'm using a custom field, formatted with "dd-mm-yyyy". I would like to use it with the Date Format defined in the Dashboard settings.
It seems alright in English with
get_option('date_format');
Or manually in French with
setlocale(LC_ALL, 'fr_FR');
$date_local = strftime("%d-%m-%Y",$date->format('U'));
But is there a way to use the localized date format of wordpress? I can't find how to give the date as an argument to
the_date() | actually I found the answer right after posting:
date_i18n(get_option('date_format') ,$timestamp);

What WordPress API function lists active/inactive plugins?
After seeing thousands of useful API functions in the WordPress core, I'm surprised to discover today that there ain't a function that would list the active plug-ins. I don't know you but I'm quite surprised at that.
I was wondering if there is a reason for missing that? If so, I'd like to know about it.
And, if there is a quick PHP snippet you know of that could give you a list of active plugins, ( the same way that a `get_post_types('','names');` does for CPT's or `get_taxonomies('','names');` does for CTs ), I'd appreciate it if you provide the code. | `wp_get_active_and_valid_plugins()`

plugin to upload to youtube via wordpress
before you say it, i know that in most situations it's _easier_ to do this the other way around (i.e. upload via yt site then embed) but i _need_ a plugin to upload/manage yt videos via the wordpress admin interface.
ive scanned through the plugin directory but cant see any good options.
can anyone suggest anything worthy?
hopefully something that uses the youtube api: <

YouTube Uploader

Adding guestbook to my wordpress site

How can i give the user permission tu publish without register? | The easiest way by far would be as you suggested to use a page coupled with comments. Restyle it so that it looks more like a guestbook.
I'm sure there are plugins out there that do this but I don't see the point as you'll need to restyle them anyway and it just slows down your site. | stackexchange-wordpress | {

Wordpress pre-build slider
Does wordpress 3+ brings a default images slider feature? Or is it just the template I downloaded?
If it brings a pre-build slider, how should I customize, add more features to it? I want to modify it to allow some content sliding features (like on: < and not only images. | No, WordPress does not have a slider feature built in. It will be either a plugin or your theme that has added the slider.
For modifying or adjusting your slider, please go to the support area for the plugin/theme you used.

When we register a custom taxonomy or post type, does the WP database modified at all?
When you use the `register post type` and `register taxonomy` functions in your functions.php, where do all that setting info get stored in regards to the CT's and CPT's you are registering?
I'm talking about the settings such as whether the CPT is public or not, which custom post types work with which registered taxonomies, whether custom taxonomy is hierarchical or not etc.
Is that all on the server memory? If so, what's the reason of not saving it on the database -for example in wp_options table?
Isn't the `wp_options` table specifically deal with stuff like this? | When you register post type it is stored in a global var name `$wp_post_types` and the taxonomies are stored in a global var named `$wp_taxonomies`
Its all in the memory since you need it all and if it was stored in the database you would need to pull it from the database and then it would still be in the memory. | stackexchange-wordpress | {

Add custom option to Standard Page Attributes Meta Box
I'd like to add a simple checkbox option to the exsisting standard Page Attributes Meta Box.
Is there an obvious/intended way to do that using the WordPress API, rather than registering a new metabox for my one new option? | Unfortunately not. The only way is to deregister the metabox, and then re-register it, supplying your own callback function which mimics the original metabox, but with your alterations (making sure the names of the inputs do not change).
This method is outlined in these posts:
* custom post type taxonomies UI radiobuttons not checkboxes
* Custom-Taxonomy as categories: Remove "most-used" tab?
Alternatively you can insert the options with javascript as outlined in:

In particular it seems that:

Moving the postbox triggers this. Some browsers/versions handle that better than others as @ocean90 mentions above but generally the editor textarea and iframe shouldn't be moved. - **azaozz** | stackexchange-wordpress | {

Want to exclude slider from page.php in header
I know this is a dumb question, but for the love of my life, I can't get the code to work. I have three page templates: home, page and another page-by category. I have a slider that I want to excluded from the default page.php file but to show everywhere else. I have tried to do this with `is_page_template` , but that isn't working. any help will be much appreciated. I'm not sure if you need my header code. If you do then leave a comment please and I'll paste in in pastebin. Thanks a lot in advance. | Did you consult the `is_page_template()` Codex entry?
If you want to query for the `page.php` page template, then you need to pass that filename to `is_page_template()`; i.e.:
<?php
if ( ! is_page_template( 'page.php' ) ) {
// The current page template is NOT page.php;
// do something
}
?>
Sidenote: if you want to query for being a static page AND not a specific page template:
<?php
if ( is_page() && ! is_page_template( 'page.php' ) ) {
// Current page is a static page AND
// The current page template is NOT page.php;
// do something
