Use different categories for a custom post
I was wondering if it was possible not to mix the categories across my different custom post ? | Do you mean having different taxonomies for your custom post types? If so, you can define custom taxonomies and apply this taxonomies only to the post types you want. If the custom taxonomy has "hierarchical" argument set to true, the taxonomy will be works the same way categories do.
register_taxonomy(
'my_taxonomy_name',
'my_custom_post_type',
array(
'hierarchical' => true
)
);
//And then

Is there a way to implement a commenting system such as that on medium or sitepoint in WP?

why some permalinks adding characters/ruining links
I am using a gallery to link to some sub categories. Some of the links within the category work exactly how they should. However there are a few that are adding strange characters on the end, I've re-done the permalinks but it still does it, you cannot see the extra characters in the link section of my gallery admin. Obviously by adding these characters, it is preventing the link from working and giving me the 404 message. It is vital to my website that my links work.
Can anybody think of a reason why they would not? I have tried disabling plugins and also looked for invisible characters.
"%20%E2%80%8E" variants of this are what is being added.
Really hoping someone can help me to solve this! Thanks. | Chances are you are copy+pasting the links in, correct? Depending where you are copying from, they could be filled with hidden space characters, like `<wbr>` in the actual HTML (if you copy from a website) which offers a break point. You need to paste these links into TextEdit, or Notepad, or Event the browser address bar to make sure no spaces are being stuck in there by mistake. | stackexchange-wordpress | {

Use different template than author.php for get_author_posts_url()
I have a client that wants two pages for each author profile:
First Page - has user info, bunch of social media links, etc. Using author.php for this.
Second Page - list of author posts
I've built everything, and here's my question:
**Is there a way to have get_author_posts_url() use a template other than author.php?** | There is a filter called `author_link`. You can use that change the URL to whatever you want.
add_filter(
'author_link',
function ($link, $author_id, $author_nicename) {
var_dump($link, $author_id, $author_nicename); // debug
return $link; // return your modified URL
},
1,3
);
The question does not have enough detail to allow for more specific code.
You can use the `template_include` hook to alter the template that loads in much the same way as the above code alters URL.
function author_archive_wpse_112852($template) {
if (/* not sure what your conditions are */) {
$template = get_stylesheet_directory().'/diff-author-template.php';

Optimising a big Wordpress site
I'm looking at optimising a rather large site I've been adding to and adding to. The database has become pretty big (maybe 100,000 posts) and it has started slowing down somewhat and giving me "Mysql has gone away"errors. I've been reading about database optimisation and have ready some people saying you should only be looking to use 1-15 queries on a page.
Do people think the suggestion that only a handful of queries should be used on any page?
Am I correct in thinking that every time I use a Wordpress function such as get_permalink() I am creating a new query and new connection the database?
I have some loops in there that literally loop through 100+ users at a time and use functions such as get_user_meta() in these loops - so would this mean I am literally making 100 database queries or are they somehow cached in Wordpress?
Thanks | Looking a the source code of get_permalink(), that function not always generates additional queries. It depends on the particular situation. get_user_meta() is always performing aditional queries although they can be stored in wp cahe.
Take a look into Save queries for analysis and this helpful plugin. You will be able to see the total number of queries, time taking by each one and other useful information that will help you to know if using a especific function is generating aditional queries or not. | stackexchange-wordpress | {

how to get number of posts in a category on a specific date
I want to get the number of posts for each category on a specific date. I think I can do the following: \- get a list of categories \- start loop \---create a query for each category and specific date loop and count posts \- end first loop
Is there any easier way to do this?
I plan to put this in the php code widget. Note I have quite a few categories | You would want to use something like this:
$query = new WP_Query( 'year=2013&monthnum=12&day=20&cat=5' );

// change monthnum to the month you want
// change day to the day you want
// start the loop
while( $query->have_posts() ) : $query->the_post();
// do loop stuff
endwhile;
wp_reset_postdata();
Above says get all posts that has ID of 5 for category and the year of 2013 and month is 12 (December) and day is 20. | stackexchange-wordpress | {

How to filter by custom post type in taxonomy archive pages
I have two custom types. One called "Questions" and other called "Files". They both share a custom taxonomy called "Types". Everything works fine, however if I go to the "Types" link inside my Wordpress admin and click on any category, it lists all the items, both in "Questions" and "Files".
Is there a way to construct a link so I could just query a specific type of one custom type instead of both?
Thanks a lot! | That is the normal behaviour. If you go the archive of one taxonomy term you will get all posts, of any type, with this taxonomy term.
One solution can be, for example, adding ?custom_type=files or ?custom_type=questions to your URLs and alter the main query in the pre_get_posts filter:
add_action( 'pre_get_posts', 'my_pre_get_post' );
function my_pre_get_post($query){
if(!empty($_GET['custom_type'])){
//limit the filter to frontend, main query and archive pages
if($query->is_main_query() && !is_admin() && $query->is_archive ) {
$query->set('post_type',sanitize_text_field($_GET['custom_type']));
}
}
}
If you want to go further you can write custom rewrite rules and add query vars to have those URLs be "pretty". | stackexchange-wordpress | {

custom post creation on front page - on submit a search is done

I have been looking at `get_current_screen();`. I have seen there is also a global `$current_screen;` that I could use.
Here are two examples:
// Using function
function wpse_post_notice() {
$screen = get_current_screen();
// Only run in post/page creation and edit screens
if ( $screen->post_type === 'post' ) {
return 'This is a post';
}
}
// Using gloabl
function wpse_post_notice() {
global $current_screen;
// Only run in post/page creation and edit screens
if ( $current_screen->post_type === 'post' ) {
return 'This is a post';
}
}
Is one method considered better than the other? If so why? | In your example, there is currently no difference. You get the same object, if there is one. Try it:
global $current_screen;
$current_screen->foo = 1;
$screen = get_current_screen();
$screen->foo = 2;
echo '$current_screen->foo: ' . $current_screen->foo; // 2!
The simple reason: objects are not passed as a copy in PHP.
**But:** global variables are really bad, because everyone can change them any time. One day far, far away, WordPress might deprecate this global variable. If you are using the function wrapper to get the object, you should be fine. Otherwise, your code might raise notices.
And always check if you get indeed an object. `$current_screen->post_type` might not exist. | stackexchange-wordpress | {

Custom filtering on month value only of an entire date field
I'm using the plugin Ajax WP Query Search Filter (< to search some custom posts I've created.
The filter works great on three custom taxonomies, however I also want to include a filter on a date field where the full date is stored.
The filter I'd like is a dropdown containing each month, as such:
* Jan
* Feb
* Mar
* Apr
* May
* ... etc...
This would search the date field on its month value. My question is how do I do this?
* dd/mm/yyyy
I know I can create a Custom Meta Field filter, but how I would get it to search on the month part only?
Thanks,
Chris. | I've solved it by creating a Custom Meta Field filter using the following options:

Update field in database for users

Best Way to Add UnEditable HTML to Posts
I find myself more and more needing to use tables or divs inside my wordpress posts content. The problem I find with this is that one wrong backspace or newline, copy / paste has the possibility to throw off the whole code. Is there a best practices when it comes to adding html inside the content? Is there a way to make it so that the user cannot delete certain things inside posts content?
For Example: On one of my websites I have an accordion. Each accordion content is seperated by `div class="accordContent"` but when the user adds a new line inside the current `accordContent` div, it ends the current div and creates a new one with the same class that throws off the code. | > Is there a way to make it so that the user cannot delete certain things inside posts content?
You need...
1. A shortcode that will generate the content. This will let your users provide input but the markup can be rigidly controlled.
2. Or a custom meta field. The markup around this can also be rigidly controlled, but to a lesser extent, or in a different way.
3. Or you need to write the markup into the templates.
I can't tell you exactly which you need. I'm not sure. I think the shortcode, or a group of shortcodes, might do what you need. | stackexchange-wordpress | {

Avoid to load default WP styles in login screen
Is there some way to avoid the load of default WordPress styles in login screen to only load my custom stylesheets?
Actually I'm using this code:
function login_styles() {
// Sets the styles if is the current theme
if (get_stylesheet_directory() == get_template_directory()) {
// Prints link to stylesheed login.css
wp_register_style(...);
wp_enqueue_style(...);
}
}
add_action( 'login_enqueue_scripts', 'login_styles' );
It works well but WordPress first loads its styles. I want to exclude that files from this screen. | Using `wp_deregister_style( 'login' )` to remove the login styles will still result in a 404'd request for the login CSS file. However, if you re-register the login style after deregistering it you can prevent the unwanted request.
add_action( 'login_init', function() {
wp_deregister_style( 'login' );
wp_register_style( 'login' );
} );
This will leave you with a completely unstyled `wp-login.php` page. To restyle it you could instead register your own CSS file under the `login` handle.
This might be more helpful than messing with the `style_loader_tag` filter.
* * *
**Update:**
`login_enqueue_scripts` is a more appropriate action and dequeuing doesn't result in a 404.

why the wp_register_script doesn't work for register_activation_hook

However, when I register my script using init hook or other hook, my code works - why? | Whatever is hooked to activation runs in just a single request when the plugin is activated in a sandbox, and the output is captured to check for errors.

Cannot display default template after switching to custom
I'm having a strange issue with a page. The site has a Default Template (page.php) and several custom templates. A page was created using a custom template (page-services.php), but then later switched to use the Default Template (all via Admin Page Attributes). However, the page's front end continues to pull the custom template instead of the selected Defaul Template.
The back end is correct (there are different custom fields depending on the template). The edit page view shows the correct custom fields for the template selected.
I can't think of any other details that might be relevant. | Refer to the Template Hierarchy to help understand what's going on here.
When you create a custom page template, it is identified as such by the header within the file, not by filename. But you've also named the file following the `page-{slug}.php` format, and as you can see in the Template Hierarchy, WordPress looks for the template named `page-services.php` for a page with slug `services`, if no custom template is assigned. In your case, they're the same file.
Rename your custom page template file so it doesn't clash with other template naming formats and this problem will disappear. | stackexchange-wordpress | {

ps. I realize that I will need to be defensive when function_b reads the flag--by making sure that the value was explicitly set, etc. | Uing OOP for your plugin it's very easy.
class MyPlugin {
static $flag;
static function function_a() {
self::$flag = 'a value';
}
static function function_b() {
if ( ! is_null(self::$flag) ) echo self::$flag; // echo 'A Value';
}
}
add_action('plugins_loaded', array('MyPlugin', 'function_a') );
add_action('init', array('MyPlugin', 'function_b') );
Not using OOP you can use `global` variables.
function function_a() {
global $myflag;
$myflag = 'a value';
}
function function_b() {
global $myflag;
if ( ! is_null($myflag) ) echo $myflag; // echo 'A Value';

Custom permalink with two parameters
I am using custom structure for permalink: `/%postname%/%page%/%year%/`.
When I navigate to ` it gives me 404 "Page not found".
Nonetheless, it is working fine with ` (without year) and `get_query_var('page');` is returning `19`. Now, I just need the value of `get_query_var('year')` instead of getting weird 404..

Building theme so user can change header image
My Google-Fu is letting me down so I'm trying it here.
I'm building a theme and I want the customer to be able to change the header image him/herself in the wp-admin. How do I go about this?
As I said my Google-Fu has been embarrasingly lacking on this one so even a link to where to start would be fantastic.
Thanks! | 1. You can add theme support in your functions file for a Custom Header page using this code which also enables you to add a default size and selector class which you can style with CSS.
add_theme_support( 'custom-header', array(
'width' => 320,
'height' => 60,
'header-selector' => '.site-title a',
'header-text' => false
) );
2. Or this method enables the user to change the header image in every page.
You can add this feature using custom fields with a header hook which isn't difficult.
The hardest part would be coding the meta box to display on all edit screens however the Codex offers a very basic example.
Another solution would be to use the code from the Twenty Eleven default theme which enables the use of Featured Images as header images on every single post or page. Slick featured for a theme in my opinion as it already includes the meta box. | stackexchange-wordpress | {

What is difference between logout and switch off?
What is the difference between logout and switch off in wordpress 3.6 except below?
1.Logut - redirect to login screen of admin.
2.Switchoff - redirect to UI side. | You have the plugin User Switching installed
From their FAQ:
> ## What does "Switch off" mean?
>
> Switching off logs you out of your account but retains your user ID in an authentication cookie so you can switch straight back without having to log in again manually. It's akin to switching to no user, and being able to switch back.
>
> The Switch Off link can be found in your profile menu in the WordPress toolbar. Once you've switched off you'll see a Switch back link in the footer of your site.
## From my experience:
The plugin allows you to switch to another user's profile and see what that user sees without knowing their login credentials. After you're done, you click on switch off to go back to using your profile. | stackexchange-wordpress | {

Check for files and database integrity
Someone started an automatic update of the WP core via dashboard today, and as it was taking too long, decided to cancel it.

For database there isn't quite any easy method (not counting native MySQL functionality). On other hand WP doesn't do _much_ to database on updates nowadays and it comes as separate explicit action (via splash screen) after file update was performed.

Is priming a Transient Cache possible?
I'm currently using Wordpress Transient Caching when querying images I've uploaded and tagged. Using Transient Caching has really sped up these queries once they are cached, but unfortunately, once the cached query expires it is only cached again when someone loads that page.
Is it possible to preload/prime transient caches so users don't get stuck with that responsibility and long wait time?
If not, should I be using something else to cache that does have that ability?
Thank you in advance for any advice | Your issue is not as much priming (which only happens first time) but that cache refreshes in solution you are using are synchronous.
Transients API is not dealing with updates by itself, it is handled by code that calls it. So it doesn't implement async updates.
On other hand there is nothing that prevents implementing async on top of it. It can be done in custom code or making use of generic solution with such functionality, for example WP-TLC-Transients library. | stackexchange-wordpress | {

So if you want secondary query also use the `s` param, pass it as argument.

// ... you have your query args here ...
);
// next line check the main query for the 's' argument and if present add it to args

Post/Custom Post Type URL Access

A lot of times we create posts or custom post types that end up being included as part of the content of a page or some other feature and are not always intended to be viewed individually.
A good example might be for a slideshow. You create a few posts where each individual post is the content of a slide in the slideshow.

There's no reason for someone to be able to access that individual post so I would like to "hide" it. | If you don't expose the permalinks on the front end, then there's no way for someone to reach them, but if you want to absolutely prevent it then set `publicly_queryable` to false when you register your post type. | stackexchange-wordpress | {

get_post_meta(get_the_ID(), 'subtitle', TRUE);
So, you are saying to Wordpress to get the meta value of the 'subtitle' field and that the returned value be in format of string. See get_post_meta() docu.
To get all meta data of a post you should use get_post_custom() function instead. For example, if you are inside the loop:
$custom = get_post_custom();
foreach($custom as $key => $value) {
echo $key.': '.$value.'<br />';
}
This will return all meta data of the post. If you want to check, for example, the "price" meta field:
if(isset($custom['price'])) {
echo 'Price: '.$custom['price'][0];

ThickBox width can't be changed in admin

Which template holds what to display when search returns nothing
Question is clear I guess.
Normally, which template is returned when no search results are found. I would say search.php, but my parent theme's (twenty thirteen) search.php looks like this (slightly edited):
<?php if ( have_posts() ) : ?>
<header class="page-header">
<h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'twentythirteen' ), get_search_query() ); ?></h1>
</header>
<?php /* The loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', get_post_format() ); ?>
<?php endwhile; ?>
<?php twentythirteen_paging_nav(); ?>
<?php else : ?>
<?php get_template_part( 'content', 'none' ); ?>
<?php endif; ?>
So, what is the `none` after `content` in the third last line? What exactly is fetched from `content.php` then? | `get_template_part( 'content', 'none' );` will look for:
1. `content-none.php`
2. `content.php`
Twenty Thirteen does have `content-none.php`.
In general this is organized in such way to support dynamic lookups where first two-part template might or might not exist and fallback to more generic template, if necessary. | stackexchange-wordpress | {

Wordpress Customise

Data won't save if metabox within conditional in admin. What am I missing?

Loading WP core Thickbox through frontend
Looking through some of the top Google results, this question has been answered a number of times, but the answers given don't seem to be working in my WP 3.6 install.
One solution given is this:
function my_thickbox() {
if (!is_admin()) {
wp_enqueue_script('thickbox', null, array('jquery'), true);
wp_enqueue_style('thickbox.css', includes_url('/js/thickbox/thickbox.css'), null, '1.0');
}
}
add_action('init', 'my_thickbox');
Another was this: `add_action( 'wp_enqueue_scripts', 'add_thickbox' )`.
I've also tried using this `add_thickbox()` with no success.
All of these approaches seem to successfully load `thickbox.css`, but no JS file is showing up. I can manually go and include the path to `thickbox.js`, but that seems less desirable given that all of this seems to be handled by the core in `script-loader.php`. | You need to add a call of `wp_footer();` function.

Remove query string except from google map api
I have an issue similar to many others in the web, but still with no solution so far.
To remove query strings i've used the following code:
function _remove_script_version( $src ){
$parts = explode( '?', $src );
return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
What i'ld like, is to know if someone believe to know how to set up a code to exclude googple map api query string from being removed.
To fix the error below:
> “The Google Maps API server rejected your request. The “sensor” parameter specified in the request must be set to either “true” or “false”.
Does anyone beleive to know how to fix this? | First of all I would like to strongly recommend you to not remove query parts of javascript and stylesheet files. Why? Because they contain a version of a file.
Why do I need it for? We need to add version to each file (whenever it is possible) to prevent versions collisions. These collisions could appear when a new version of WP/plugin is released and you update it from admin panel. In this case, your users' browser won't be notified that a new version of a script exists and won't download it, but will use previous one which is stored in browser cache.
But if you strongly confident that you don't need it and still want to trim query strings, you can do it by changing your function to the following view:
function _remove_script_version( $src ){
return add_query_arg( 'ver', false, $src );
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );

Custom Stylesheet instead of Inline CSS for Wordpress Customizer API Overrides
I've looked at Wordpress Customizer API and it looks to be able to achieve what I'm looking for; allowing the developer to set aside as many dynamic styles which can later be configured by the Wordpress admin.
However, the recommended mechanism for injecting the styles is really not cool. All guides I've read online and from Wordpress recommend they be added inline to the Head of the document.
With the popularity of such documents flooding the net I was unable to find a definitive guide on how to add these codes neatly to a stylesheet! Can get theme mod() be called from a PHP stylesheet? Sorry please bear with me as I'm just weeks into PHP and Wordpress documentation.
Any suggestions would be nice I'm sure there are many developers who would not accept inline CSS. | > However, the recommended mechanism for injecting the styles is really not cool. All guides I've read online and from Wordpress recommend they be added inline to the Head of the document.
That's how HTML works, no fault of WP's. Dynamic stylesheets have always been a challenge since CSS is not dynamic language by nature.
There is number of options, which all can be implemented relatively neatly in WordPress, however all have drawbacks.
1. Inline styles. Bloat page source size, but just work.
2. PHP script serving CSS. Highly flexible, but serving extra PHP script is orders of magnitude slower than serving static CSS file.
3. Compiling and serving static CSS files. Somewhat challenging to implement (especially in code for public use), but has least performance drawbacks.
Overall the way to go depends much more on your performance requirements and how will final product be used, than specific option. There is no winning one here. | stackexchange-wordpress | {

How to implement filesystem cache in Wordpress
I'm currently using the Transients API to cache some product details from Amazon. Now I'm looking into adding a file system cache. But I have no idea how to implement it. The only thing that I can think of is to actually save the JSON string representation of a specific product into a text file. Is this worth it? Are there any proven performance benefits when doing this or does it have the same performance to that of the database? Thanks in advance. | Some of caching APIs in WordPress, including transients, can make use of swappable Object Cache backend. There are ready-made implementations around for it which use file system as storage engine.
However determining if it's worth it is another matter entirely. In _usual_ case database is very likely to outperform disk for typical caching tasks. However there are combinations of factors out there that _might_ make disk preferable (when data gets prohibitively large for individual database entries, etc).
Unless you can practically benchmark and determine limitations of your current setup it's unlikely that you need dedicated file cache.
PS note that more commonly Object Cache backends use memory caches (APC, Memcache, Redis) and that unsurprisingly tends to outperforms database and disk either for caching tasks | stackexchange-wordpress | {

Put CSS on TOP, how?
I have this mission, that regards setting my existing CSS on HEAD. I've tried to make a search on if there was any kind of plugin or code to automatically set the CSS code directly in Head. The main purpose is to follow YSlow recomendations such as "Put CSS on Top"
How can i do that? Is there a code for it? a plugin?
Does someone believes that can help me with this?
My domain is < | Would be interesting to see if you get the same YSlow message when checking your site without any plugins. Its a little difficult to be sure because of the minification of HTML/CSS on your site, but it seems some of the plugins are not inserting stylesheets in to the `<head>` part of your document, and placing them when they appear instead.
From my understanding of YSlow's documentation < it helps to ensure progressive loading - or in other words, the visual loading of the site for the end user is enhanced.
If a fresh install of your theme (perhaps on a test site) results in the same YSlow message, then feel free to ignore the above.
