Change Font Size on Blog (Twenty Twelve)
I have a Twenty Twelve child theme. I love the fonts on the site. I am willing to live with the normal font size that Twenty Twelve has on pages like the home page. However, on pages like the blog, I want to have a nice big font that is easy to read (see the size on Medium.com). The questions is how do I increase the font size on the blog posts only, and not the rest of the site. Thanks in advance, Shaan | Try to add those styles with the CSS class `.single` or `.single-post`. Because it's a child theme you'll probably need to use `!important` | stackexchange-wordpress | {

Custom post type within a subdirectory
I've searched around but have not been able to find an answer to my question.
What I'm trying to do is create a custom post type that exists within a sub-directory, not just after the root as is default.
For example right now I have:
<
I would like to have:
<
The reason I'm trying to do this is that I have a client that now has additional clients that I would like to have named as a sub-directory, and not an entirely new sub domain.
I was planning on creating custom post types to create the additional blogs or the two other clients, but I can't find a way of having a sub-directory first.
Is there an easy way to do this? I'm decently versed in WP but not an expert, so I'm hoping there is an easy-ish method.
Thanks for any guidance | When you register your post type, add the subdirectory to the `has_archive` argument, and as the `slug` argument of the `rewrite` argument:
$args = array(
// ... other args removed for clarity
'rewrite' => array( 'slug' => 'subdirectory/custom-post-type' ),
'has_archive' => 'subdirectory/custom-post-type',
// ...

The conditional logic only works to show or hide?
I am using the Advanced Custom Fields for custom fields in the User Profile. I use conditional logic to display one of between four fields, each field will be displayed according to a radio field option previously clicked.
In this case only one option would can be sent. But, when the user update your profile all four fields are being sent.
The conditional logic in this case is only serving to show or hide.
Some tip on how to improve this?
I appreciate any help. | This is a limitation of how showing/hiding fields works with Javascript, and how Wordpress saves meta-data. Probably the best way to handle it is to use the same type of switch logic where you want to use the data. something like this:
switch ( get_field('radio_field') ) {
case 'first_option':
// get data from your first field
break;
case 'second_option':
// get data from your second field

Strip post_tags from list of returned taxonomy terms

Why tags are displayed bellow the content and not inside
I am developing a theme for myself and I was wondering why wordpress tags are allways displayed bellow the_content.
I know that this can be done via shortcode, but I would like to know if this is for seo purposes, or there is any technical reason?
I´am asking because I didn´t find any information on the web...
My code:
in functions.php (found in here)
function tags_in_post($atts) { // [tags] outputs post's tags in a span
global $post;
$tags = '<span class="post-tags">';
ob_start();
the_tags( '<span class="post-tags">', ', ', '</span>' );
$tags = ob_get_contents();
ob_end_clean();
return $tags;
}
add_shortcode ('tags', 'tags_in_post');
Than this shorttag [tags] must be used inside the wordpress editor.
Thanks | So if I look closely, seems our actual question is "Why does WordPress put Post Tags at the bottom of a Post?"
The answer depends on the theme, of course. But, most themes put them after a post's body so that you can use it as part of browsing away from that post, to get involved with further reading. Basically like saying, "You've been reading about: Toys, Babies, Books" where each of those items is a link to, presumably, articles on those topics.
The idea of having them at the end of the article is so you don't get bored too quickly and jump off to read something else.
Unless you mean something else by `tags` as that can be a pretty vague thing around these parts. | stackexchange-wordpress | {

Any other ways to this | This is more of PHP implementation detail. If you want a precise match you can do something like:
if ( isset( $words[$translated] ) )
return $words[$translated];
return $translated;
PS you might want to declare `$words` as static, so that array is reused and not continuously re-created on each function call (which would be _a lot_ of calls with `gettext` hook). | stackexchange-wordpress | {

Remove wordpress author's capability to moderate comments on their own posts
WordPress authors have permission to edit others comments on their own post. How to disable this and still allow the authors to edit their published posts? | From quick look at code the likely permissions check for that is `edit_comment` capability in `edit_comment()` function.
Your options to remove that capability roughly are:
* customize the role with plugin, for example Members
* customize role with code, probably using remove cap functionality
* filter thiungs around `map_meta_cap` or `user_has_cap` if you need to achieve more elaborate logic (for example denying permission in context of specific comment, rather than comments in general)
PS not sure if this will properly omit related parts of interface, might need to deal with that separately | stackexchange-wordpress | {

Is there a reason I cannot get the current category in a loop?
I think I am doing this wrong but if I do:
if(have_posts()){
$category_id = get_query_var('cat');
var_dump($category_id);
while (have_posts()){
the_post();
}
}
the var dump comes back empty. Why? Is there a better way to get the current category object in a loop? the same question applies to tags. Can I also get the current tag object if this was a `is_tag()`? | `get_query_var` will get the category from the main query, and it is only going to be set for some pages, such as category archives. It is not set for "single" pages or tag archives or a many other kids of "pages".
The value that `get_query_var` returns is something like a 'search' variable. It will be set when the query is instructed to look for posts in a particular category. It doesn't reflect the value of current post in the Loop, though of course if `get_query_var('cat')` is set then all posts should be assigned to that category.
What you want to get the category for the current post in the Loop is `get_the_category`, but it should come after `the_post`. `get_the_tags` will do the same for tags and the more generic `get_the_terms` can be used for any taxonomy. | stackexchange-wordpress | {

How to best delete orphan wp_postmeta
I'm in the middle of doing some fairly complex queries involving metadata from a custom post type. Unfortunately if any posts are deleted the metadata stays put which complicates matters as I am counting it.
I was wondering how best to go about deleting the orphan metadata in the event that the post is deleted.

I found an SQL query that does just that but I'm not sure how to format it.
DELETE pm
FROM wp_postmeta pm
LEFT JOIN wp_posts wp ON wp.ID = pm.post_id
WHERE wp.ID IS NULL
I tried it in phpmyadmin on a backup copy of my database but to no avail. | This snippet is good enough, use it with `$wpdb`. In this case I would use :
<?php
add_action( 'before_delete_post', 'my_func' );

// We check if the global post type isn't ours and just return
global $post_type;
if ( $post_type != 'my_custom_post_type' ) return;
// My custom stuff for deleting my custom post type here

How do I disable a plugin enforced by my host (in mu-plugins)?
My host makes mandatory two plugins which get automatic updates under mu-plugins folder.
Is there a way I can disable them with some trick, for example with a plugin folder of the same name under my local plugins folder or by duplicating some function and make them empty? | You disable mu-plugins by removing the plugin file from the `mu-plugins` directory. They are outside the normal plugin activation/deactivation cycle "and cannot be disabled except by removing the plugin file from the must-use directory, which is found in wp-content/mu-plugins by default." I assume you don't have the authority to remove the files.
The plugins may be using hooks and you may be able to remove some actions or filters and disable all or part of the plugins functionality, but without knowing how the mu-plugins work it is impossible to say how.
But... I suspect your host would **_shut down your site_** if you succeed in circumventing something they _require_.

add_post_meta -- not working

Any suggestions? | What user34296 said is `update_post_meta()` will update the value of the existing meta key (custom field) for the specified post. If it does not already exist it will call `add_post_meta($post_id, $meta_key, $meta_value)` instead. That's why you should use it.
**EDIT: in this case it should work, error is coming from another part of the code.**

How to programatically change username (user_login)?
As in the title, how to programatically change user's login?
I wanted to use `wp_insert_user` function, but it appears that when updating current user, it doesn't change their username. Should I use `$wpdb->update` for that? If yes, how would code for changing username look like? What consequences would changing user login have, given that WordPress API doesn't allow changing usernames? | I was sure that `wp_update_user()` should do this.
It even gets user_login as param, but it looks like it ignores it, when you set this param.
So this code looks OK, but it doesn't work as you wish it did :( :
wp_update_user(
['ID' => $user_id, 'user_login' => $new_login]
);
You have to call custom SQL query to update user_login:
global $wpdb;
$wpdb->update(
$wpdb->users,
['user_login' => $new_user_login],
['ID' => $user_id]
);
It works OK and I don't think it has any serious consequences, because WP uses users ID to assign posts/comments (and so on) to user.
The only problem I can think of is that when this user is currently logged in, he will be logged out after user_login change. | stackexchange-wordpress | {

Auto-fill Custom comment fields
Thank you for reading,
I added custom fields to the comment form, and saved the input in the DB, following this tutorial <
Now i'd like the meta-fields in the comment form to auto-fill after the user has commented once.
Just like wordpress does with the Name, E-mail and Url; once you've commented the value stays in the fields. However, wordpress does this with $commenter['comment_author'] and this array doesn't have the data I'm looking for. | You can store these values in cookies and fill them when you are creating form inputs.

Apply the_content filter to a custom field with multiple values

foreach ($video as $vid) {

echo '<li>'.apply_filters('the_content',$vid).'</li>';

$lis = '';
foreach ($video as $vid) {
$lis .= '<li>'.$vid.'</li>';
}
echo apply_filters('the_content',$lis);
I haven't benchmarked the one versus the other but given that the latter calls the filter once and the former many times, I'd bet on the latter. | stackexchange-wordpress | {

Custom theme template files
Im trying to create a Theme from scratch, its quite challenging, cause im new to WP. I follow this developing process at Teamtreehouse. All is very good, its just, im puzzled with the template file creation.
Its all fine with `front-page.php` and `home.php` files, but eventually I want to have as well the: `partnership.php`, `gallery.php`, `contact_us.php`, `prices.php` files too.
Anyhow, when I created the `partnership.php` file and linked it to display the Partnership webpage title with testimonials and link to the webpage, I got default `index.php` to display. I understand that WP will display the `index.php` if it does not find any other file in the structure, but the files are all in the `example.com/wp-content/themes` directory. Im working on localhost.
It seems that WP did not recognize the custom template files.
Share your thoughts on this please.
Many Thanks | If you want to use custom page templates, yo have to:
1. Create file for your template.
2. On beginning of your file add comment defining that this file is custom template file (`/* Template Name: One column, no sidebar */`).
3. Manually set that chosen page should use this custom template.

How to include Related Posts in WP RSS feed not use plugin? I have search around on google and stackexchange but have no result about this. Thanks all friends! | You have to use `the_content` and `the_excerpt_rss` hooks. You can do this like this:

$content .= $related_posts_html;

Comments: Approve when admin Replies, from the Front end
Thank you for reading,
In the admin panel, when a comment is awaiting moderation, you can "Approve and Reply" in the same action.
However, in the front end, if you show the awaiting comments to the admin, and she hits Reply, the comment wont approve.
Does anybody know how to get the proper link, or where modify the code, to auto-approve comments when the admin replies ?
**Why:** I'm creating the site for a client, and trying to make it as easy as posible so she won't need to learn WP's admin panel. | Well... All you have to do is to check what hooks are available during comment posting.
The one I think might be helpful is `wp_insert_comment`. So you could do something like this:
function my_wp_insert_comment($id, $comment) {
if ( is_admin() && $comment->comment_parent ) {
if ( wp_get_comment_status( $comment->comment_parent ) == 'unapproved' )
wp_set_comment_status( $comment->comment_parent, 'approve' );
}
}
add_action('wp_insert_comment', 'my_wp_insert_comment', 10, 2);
Just place this code in `function.php` file of your theme. This function will be called every time a comment is inserted into database. No matter how (from admin area, front end or by some plugin, etc.) | stackexchange-wordpress | {

Wordpress for questions and responses website
I am using Wordpress to create a Q&A website.
The question is returned by `the_content.`
If I store the answers as post meta field array:
{
[1] => 'first answer',
[2] => 'second answer',
[3] => 'third answer',
.....
}
How can I create separte comments for each item (comments for question, then comments for first answer, then comments for second answer....)?

If I reuse it, it will display a new comment for all the items. `comments_template` doesnt have a pramater to identify a list of comments against other lists. | (adding answer from comments above)
Set up your Responses as a Custom Post Type. Then you can use WordPress's native comment system for, well, comments on the Responses.
To tie the Responses to the Questions, you can simply use something like `update_post_meta( $response_id, 'question_id', $question_id );`. See `update_post_meta()` for details. | stackexchange-wordpress | {

Prevent child theme from inheriting a parent theme's required file

Can I use a form in a dashboard widget?

Is there a WordPress API to do something like that? I already know how to add a dashboard widget, but I don't know how to make a form in a dashboard widget / how to process the data.
The only thing I can think of is to redirect the user to my options page - there must be a neater way. Is there any? | There are two options to use forms in a dashboard widget:
1. Use the parameter `control_callback`. See the Codex

'my_render_widget', // $callback
'my_control' // $control_callback
);
function my_control()
{
// print some form elements, WordPress will handle the <form> tag.
}
2. If you want to use a form in the main display handler, set the form action to `admin-post.php` and add a callback function for a custom `action` there. Example. When you are done processing the form redirect back to the dashboard. | stackexchange-wordpress | {

Custom Post Type Template based on Taxonomy
I have a custom post type, Vehicles. Vehicles have a custom taxonomy, new or used. Naturally the vehicle pages use single-vehicles.php but I would like to differentiate between new and used vehicles by somehow using different templates automatically based on whether they're new or used.

} else {

Refresh page using Cron after any post is published

I ve'been trying to google that info, but it seems that nobody were ever interested or it seems as impossible. | Well, I don't think you can do this with cron.
Browser sends request to server and gets response. It isn't connected permanently to your server. So if you want to refresh page which is already displayed in browser, you have to force browser to send request for this page one more time (do refresh).
Another way would be placing some JS on your page. It could send AJAX request every few minutes (or so) to your server and check if there is anything new to show and process them in any way you'd like. | stackexchange-wordpress | {

Function to add class to <form> element?
I'm using the Sidebar Login script by Mike Jolley, I would like to add a class of "clearfix" to the element tag. I have been unable to find a solution to this so far.
I'd also like to understand any solution given, so if you would like to briefly explain how the function works I'd be very grateful. | That plugin does not create a `<form>` tag itself. It uses `wp_login_form` to do that, and that function does not provide a way to add a class to the `<form>` tag. You can see that by looking at the `widget` method, which is what generates the front end content.
I don't see a way to do what you want to do, but there is an action before the form-- `do_action( 'sidebar_login_widget_start' );`\-- and one after-- `do_action( 'sidebar_login_widget_end' );`\-- that would let you wrap the whole form in some other markup.
However, I very much doubt that you need to add a class to that tag. I would bet that you can do anything you need by writing CSS rules using the existing markup. | stackexchange-wordpress | {

English version of my site show french strings
This is a weird one :
< is the french version of the site < is the english one
The problem is that the english version show theme strings in french.
I have no idea why.
Infos : i use WPML and the network of websites wordpress features. | If these theme strings are prepared for translation and the theme is not in english by default (they're outputed with `__()` or `_e()` functions) and you include your theme textdomain correctly, then you probably haven't translated these strings to english.
WPML had/has some tool to do this, but it isn't very user-friendly (at least I don't like this tool). I'd suggest using Codestyling Localization plugin.
Install it, rescan your theme directory (it will find all translation strings) and then add missing translations. Don't forget to build `.mo` files after translating strings (without it new translations won't work).

Add site options UI in Multisite Sites > Infos page

Any suggestion ? | I finally found a way to add more lines to the Sites > Infos table : !My own option in the Sites > Infos table
It's a little bit ugly, but it works. I simply use the action `admin_footer` to add a bunch of HTML code at the end of the page, and then use jQuery to move it to the right place.

<td><input type="text"/></td>
</tr></table>

$('.form-table tbody').append($('#user16975_custom_options'));
});</script><?php

!is_admin() condition turns true in admin pages
I need users to redirect to login if not logged and once they are, redirect them to backend if they try to see front end pages. This is my code:

if(is_user_logged_in() ):
bk1_debug('logged in');
if (!is_admin()):
bk1_debug('not in admin, redirecting...');
wp_redirect(admin_url());
endif;
else:
bk1_debug('not logged in, redirecting...');
wp_redirect(wp_login_url( admin_url() ));
endif;
}, 10 );
Of course it doesn't work... For some reason 'not in admin, redirecting...' is called also in backend, and even better, in front end nothing happens altogether! Only redirecting for not logged in user goes.
Any idea? | Following suggestions from @s_ha_dum who noted that user need be logged in anyway to go to back end and that 'template_redirect' doesn't work in backend (even if my code did trigged console messages only in back end), I simplify the code as such:
add_action( 'template_redirect', function () {
if(!is_admin()) wp_redirect(admin_url());
}, 10 );
But nothing changed. Still I go to front end and nothing happens. I also tried with 'init' and nothing.
Then I thought that maybe I was calling 'template_redirect' in the wrong moment, so I mixed the two hooks:
add_action( 'init', function () {
add_action( 'template_redirect', function(){
if(!is_admin()) wp_redirect(admin_url());

Pagination posts. Url format
i'm using pagination for very long posts. So i have a problem here. I'm not happy with standard utl structure (where is couple personal reasons for that in my project). For example, i have post
/post.htm
and i need to get second page of it with
/post2.htm
not
/post.htm/2
I'm sure that i won't create post/page with slug post2 How can i change standard url in a such way? I tried this
add_action( 'init', 'wpa5413_init' );
function wpa5413_init()
{
add_rewrite_rule('^([^/]+)([0-9]{1,2}).htm$','$matches[1].htm/$matches[2]','top');
}
But it doesn't work... | Your rewrite rule format is not correct. The `$rewrite` argument must point to `index.php` with query vars set so WordPress can create the default query:
add_action( 'init', 'wpa103850_init' );
function wpa103850_init()
{
add_rewrite_rule(
'^([^/]+)([0-9]{1,2}).htm$',
'index.php?name=$matches[1]&page=$matches[2]',
'top'
);
}
However, this will still not work correctly, due to the canonical redirect. WordPress wants to enforce a single URL for any given post/page. You'll have to remove that filter to prevent that from happening, but note that this will have other possibly undesirable side-effects, as no canonical redirects will happen.
remove_filter( 'template_redirect', 'redirect_canonical' );

You need to check the query object passed to your function hooked to `parse_query`:

Only Display a Featured Image on First Post Page
In WordPress a single post can be divided into multiple pages using page-links.
Currently, I use featured images on my post pages and call them by size, as shown below. If an image is larger than 500 pixels it is displayed as the top-post thumbnail and if it is smaller than that it displays as the standard thumbnail.
<?php $image_data = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' );

if ( $image_data[1] < 500 ) { the_post_thumbnail();
} ?>
The problem is when I include this in my single-post.php it shows up on every page of a post, even when that post is divided by page-links. How do I make these images only show on the first page? | Use the global `$page`, which holds the current page number.

Minimal WordPress load for only `get_option` to work (because ajax...)
In a plugin, I use ajax to `get_option()` which takes much longer than it has to because entire wp gets loaded.
How do I set things up so that it (my ajax) loads only what is needed? (`get_option()`)
[](
[]( | If you're building something for public consumption (a plugin, a theme, etc) use `admin-ajax.php` like you should because that is the appropriate and accepted way to do things and gives your end users the power they need to change and modify things if they so choose.
Beyond that, the best you MAY be able to do is use the `SHORTINIT` constant. Define it in a custom php file, then require `wp-load.php` and do what you need to do. `SHORTINIT` stops most of the WordPress core from being loaded.
<?php
define('SHORTINIT', true);
require '/path/to/wp-load.php';
// you'll have the basic API here, including `get_option`. Do stuff.
If you do this outside the WP core, you'll have to _guess_ where `wp-load.php` may be -- you won't have any `ABSPATH` contant to guide you. That's a risky bet unless you're in full control of the system. In other words, if this is a custom, not publicly-released thing, go for it. Otherwise, use `admin-ajax.php`. | stackexchange-wordpress | {

Removing the main link to Jetpack from the menu
I need to remove the link to the Jetpack settings, but not the links to Omnisearch and Site Stats from the admin menu for everyone not having an administrator role:
!enter image description here
For this, I came up with this code:
function remove_posts_menu() {
if (!current_user_can('administrator')) {
remove_submenu_page('admin.php?page=jetpack', 'admin.php?page=jetpack');
}
}
add_action('admin_init', 'remove_posts_menu');
(Reference for the `remove_submenu_page()` function)
However, this doesn't work. I did check that the function is called and so by adding `remove_submenu_page('tools.php', 'tools.php');` \- when this is added to the function, just after the removal of the Jetpack settings link, the Tools link is removed, but the Broken Link Checker link (of a plugin I installed) is still visible.
What's the correct way to remove the Jetpack link? | Try this instead:
function remove_posts_menu() {
if ( ! current_user_can( 'manage_options' ) )
remove_submenu_page( 'jetpack', 'jetpack' );
}
add_action( 'admin_init', 'remove_posts_menu' );

What could cause a WP Option to get truncated?
I have a WP plugin, where all admin setting field values were suddenly changed to the letter 'a'. All settings are stored in one 'big' option in the table. Seemed like the serialization gone wrong.
I run a `var_dump` on the `get_option` value and it returned a truncated string, not an array as usual. I'll update the question once I can reproduce the truncated string again.
I only use the 'Save changes' button and let the WP Options API write to the option, getting the values from user changeable or hidden HTML fields.
Is there any special characters or similar that can prevent an option from being written properly which could result in the serialized array being truncated?
The cause has something to to with Instagram or an Instagram user name. | It was a character. Make sure you sanitize everything that gets written as field values, even if it's a username.
trim(preg_replace("/[^\w\s]+/", "", $user->full_name))
I assumed there are no special characters in Instagram usernames. Never assume. I don't really use Instagram, just my plugin supports it. BTW it got truncated on the first occurrence of the special character. | stackexchange-wordpress | {

Hook in a sidebar widget and add some markup
I'm looking to hook into a sidebar widget, this one in particular loads the members.
All I'm looking to do is add a link into the widget, I managed to get a result but it's not quite right. It doesn't load the original function, instead it replaces it.
Here's how I far I got:
function members_dir_link(){
echo '<a href="/members/">View Members</a>';
}
add_filter('bp_has_members','members_dir_link'); | I don't think it can be done. I'm sorry, but this widget has no hooks in there. You can only use `bp_has_members` hook, but you shouldn't use it to echo anything, because it's used in many other places, so you may break some things doing it this way.
The only way I can see to achieve this (and it's not perfect), is to write your own widget based on this BP widget. To do that you should:
1. Find the original widget's source code. (It's in `bp-core/bp-core-widgets.php` file)
2. Copy it's code and place it in your themes `function.php`
3. Rename it properly (take care of class name, and so on).
4. Register your new widget with:
add_action('widgets_init', create_function('', 'return register_widget("");') );
You can also try to inherit this new widget class from original BP widget class (you won't need to copy entire source code then). | stackexchange-wordpress | {

Automatically adding a link to the next page link before '<!--nextpage-->' tag in posts?

bbpress Not Showing: How to troubleshoot?
BBPress isn't showing on the front-end in a custom theme I've built and I can't figure it out. I activated TwentyTwelve and it shows, so I know it's not a plugin. I also cleared out functions.php and that didn't have any impact. How do I begin troubleshooting from here? | The "most" stripped-down theme I can think of that can run **BBPress** is just a single `index.php` file containing:

if ( have_posts() ) :
while ( have_posts() ) : the_post();
the_content();
endwhile;
else :
_e( 'Nothing!' );
endif;
// get_footer();
?>
So my guess is that your `while` loop is missing something or you are overwriting the `the_content` filter used by BBPress!
Well, taking the extreme, it looks like it's possible to run it with the following one-liner in `index.php`:
<?php the_post(); the_content(); ?>

why the same code got different results when using query_posts in functions.php and index.php
I am using WordPress 3.5, and my blog sites have many registered users. After they log in, I want them to see just their own posts, not others.
So I added this to my `functions.php`, but I get a blank page.
function only_login_user_post_on_homepage() {
$current_user = wp_get_current_user();
query_posts('author=', $current_user -> ID);
}
add_action( 'pre_get_posts', 'only_login_user_post_on_homepage' );
So, I comment out the `add_action`, then go to `index.php`, add the same code:
$current_user = wp_get_current_user();
query_posts("author=".$current_user -> ID);
Yeah, got the results, I don't know why? The code are the same, but why I got different result. | In your first code example, you hook into the `pre_get_posts` action, which fires during the main query. But instead of manipulating _that_ query, you trigger another one using `query_posts()`, which fires the hook again, and you end up with an infinite loop.
With the second code example, you're just overriding the main query after it's occurred. But whilst it works, you've ended up with a redundant, time-consuming query.

How to rename theme's root directory?

define( 'WP_CONTENT_URL', '
define( 'WP_PLUGIN_DIR', $_SERVER['DOCUMENT_ROOT'] . '/extension' );
define( 'WP_PLUGIN_URL', '
So, how to rename the theme's root folder like this way? | Although @TheDeadMedic is technically correct and you can't rename the `themes` folder. You CAN change some of the public facing urls.
For example, you can make a new folder `assets/new-themes` and add your CSS, and images there. Then make a theme include your styles.css (which can be just the header info) and anytime in your theme you want to refer to any image, css, or JS (public urls) set that to your new theme folder (or CDN if your fancy)
I'm not sure how changing the name of the directory would improve security as there are so many ways to find out if someone is using WP but that's just one way to apply a similar effect.

Using a nonce in a Custom Login Form
I am trying to create my own login form for WordPress using wp-login.php as a template.
In the form that is used to collect login information from the user (lines 680 through 703 of wp-login.php), there doesn't seem to be any implementation of a nonce.
I have been told by quite a few people that I should always be using a nonce when collecting information from forms - but there is not a single reference to a nonce in this entire file - despite their being four fairly critical forms.
So - what am I missing?
I know that the login form uses a testcookie and that you create a securecookie when reading through the POST information - but does that somehow solve the security issue? Are there any good resources out there for understanding how secure cookies work in this instance? | > using wp-login.php as a template.
is not a correct way to do that.
Source
You'd better use the wp_login_form() function in a custom template.
EDIT:
And if you want to add an option to reset password you could do this :
add_action( 'login_form_middle', 'add_lost_password_link' );
function add_lost_password_link() {
return '<a href="/wp-login.php?action=lostpassword">Lost Password?</a>';

Get posts in a subcategory of a chosen parent

'post_status' => 'publish',
'post_type' => 'post',

So your function should look like this:
function getPostsInCategory($category) {
return get_posts(array(
'post_status' => 'publish',
'category' => $category, // e.g '3' catgory is passed as 'cat' param of WP_Query, so it will display posts from children categories as well

Changing RSS feed URL structure
I am in the process of creating a wordpress website, and I just have one issue left - RSS feeds.
Currently, the website has a `.htaccess` file blocking access to `/category/*` pages. It was part of a requirement that the site is not obviously Wordpress, and `/category` is a decent indicator of that.
Each category is fronted by a page, which displays the category content - so `/category/news` becomes `/news`.
However, RSS feeds always seem to point to `/category/xxx/feed` \- is there a way to remove this `/category/` part? So people could view the RSS feed at ` ?
I've tried fiddling around with the `.htaccess` file, but it's the one area of building a web application I'm not 100% sure on. Every search has returned with results of how to point a feed to Feedburner instead, which is not what I am looking to do at all. | I found (in my opinion) the best and easiest way to do this, and thought I should leave it as an answer in case anybody stumbles upon this thread.
I downloaded and installed the WP No Category Base plugin and that did exactly what I needed.
Unfortunately, I never got around to trying the other answers (had to move on to a more urgent project), so I can't clarify if any of them work.

register_theme_directory and broken deploys

// do step two
