Different page template for paginated content?
Sorry for the basic question, but I can't track down a solution (or maybe it's just hard to search for).
I'm creating my own infinite scroll system for a wordpress site I'm working on. For ease of development it would be beneficial for the 'paginated' content to be on a separate template (so that I can just output the content, and ignore the rest of the template). Can this be done in wordpress?
i.e.
`domain.tld/content-page` should use `content-page.php`
`domain.tld/content-page/page/1` should use `content-page-paginated.php`
I suppose the obvious alternative is having logic in content-page.php that checks to see if it's paged content and outputs differently if that's the case. | > I suppose the obvious alternative is having logic in content-page.php that checks to see if it's paged content and outputs differently if that's the case.
Basically.
In `content-page.php`:
get_header();

global $paged;
// If post/page isn't paginated
if ($paged === 0) {
//Do stuff that you want for non-paginated posts/pages

Theme specific plugin, how?
Can someone tell me whether it is possible to create a plugin that is only available to a specific theme and how do I override certain settings in that theme?
**The problem** This is basically the story. We've had a third party design and create a wordpress theme for us. Now it's up to us to expand the functionality of the theme by creating a plugin that will only be valid when someone has our theme installed.
Are there specific functions available to achieve this?

Why use the Settings API over a new administration menu?
I'm writing a 'quote-me' plugin which provides the end-user with a quote based on data they submit through a front-end form. The quote is calculated according to a price list. The price list varies depending on the time of year so I need a way of letting the admin-user update the prices via the back-end dashboard.
My first thought was to use the Settings API but have since seen administration menus can be created.
Considering my objective above, should I create a new admin menu or should I use the Settings API? Which is more appropriate for my use case and why?
Hoping someone can explain. Thanks in advance.
**UPDATE:**
My confusion came from my assumption that the Settings API is to be used for just the _Settings_ administration menu. But now I know the Settings API can be used across the whole set of administration menus, including new ones I create.
Thanks for your answers and comments! | The two are not the same thing at all, and likely you'll use both.
The Administration Menu stuff shows you how to create the menu item and page for your settings to live on. In other words, the menu item in the left hand bar, and the existence of the page itself.
The Settings API is what you use to actually build the contents of that page (the table of settings, form fields, and submit button), and to then process the data coming back from it. | stackexchange-wordpress | {

Why does enabling Permalinks make pages not found?
I'm new to Wordpress and am creating a site using v3.9.1 of WordPress. When I create a new page, I can see it in edit mode, but the URL it is supposedly creating is not found when permalinks is used, but visible when permalinks is disabled. For example, if I try to create a page called `photos` right below the top level, the editor states the page will be visible at ` when permalinks is `Post name`, but navigating to such page gives the error:
> Not Found
>
> The requested URL /photos/ was not found on this server.
But if I put Permalinks back to `Default` then it becomes visible at ` | This is a Site I maintain hosted on GoDaddy. All HTML seen by the outside world is stored in the `/public_html` directory. Therefore `/public_html` is considered the root directory of my server.
!FileZilla Photo
This site runs on WordPress 3.9.1. All that was done, was that GoDady's custom installer package unzipped the WordPress download zip to the `/public_html` directory. Doing this Manually is easily accomplished by unzipping the WordPress download to a Folder and then uploading the **contents of that Folder(but not the folder)** to your web root. I suspect you unzipped and then uploaded the containing folder, which would lead to `www.example.com/wordpress` if wordpress was the folder you uploaded.

Making a Custom Menu Sidebar Icon show as Current in css

Add character count to custom metabox
I know of a way to add a character counter to the excerpt metabox in WP, but I would like to add a character counter to a custom metabox. The following script is getting the counter in the metabox, which has tabs, but it isn't counting. Any help would be great. Thanks, it's my first question in StackExchange.

jQuery("#feed").val(jQuery("#excerpt").val().length);
jQuery("#bgnp-metabox-tabs").keyup( function() {
jQuery("#bgnp_metabox_tabs").val(jQuery("#excerpt").val().length);
});
});
The counter appears in all of the tabs, but I only want it in the tab "#feed" | I assume the `#feed` element is the one in which you want the count value to appear? If so, change the `#bgnp_metabox_tabs` entry in your keyup function to `#feed`.
**EDIT:**
For some reason, I wasn't seeing all the code when I first read the problem.
The id of your placeholder for the character count is the same as the id on which you are calling the `after` function. I would change the placeholder id to something like `char-count`.
You can then target that placeholder with `jQuery(#feed #char-count)` to get it to be shown only on the feed tab (assuming the feed tab has an id of `#feed`) | stackexchange-wordpress | {

Get markup for post without loading into the template
I am writing a shortcode plugin that displays posts according to some parameters passed into the shortcode. I have the `wp_query` to get the posts and now I am trying to get the markup for the posts according to the theme's template files.

How do I prevent term from being created on create_term hook?

Is there an action hook that fires just before a template is loaded?

So if it's going to run index.php, just before it starts reading code from line 1 of index.php, some hook would be super useful.
Anyone know one? | Looking at the Action Reference in the Codex, the first action listed after the `wp` action that sets up the WP object is `template_redirect`, which is indeed fired after all queried data is available, and before a template is selected. You can use the WordPress conditionals to determine if your intended template file will be loaded.
There is also the `template_include` filter which is executed after a template has been selected but before it is loaded, and gets passed the selected template file as an argument. But you should note that as this is a filter hook, it's intended purpose is to replace a selected template rather than adding or removing functionality.
Alternately, if you are using your own theme, you could call `do_action( 'my_custom_action' );` at the top of your template file and simply add hooks to the action to execute custom functionality. | stackexchange-wordpress | {

if ( ! empty( $value ) )
… and `empty()` is `TRUE` for values like `0` or `"0"`.
You have two options now:
1. Filter `walker_nav_menu_start_el` and replace `<a` with `<a tabindex=0`.
2. Pass `$atts['tabindex'] = "0 ";` in your original function. Note the extra space. It circumvents the `empty` check. Test it with different browsers. | stackexchange-wordpress | {

WP_NAV_MENU filter targets all menus
Im trying to replace my template's primary menu through a plugin so that I don't have to make changes to the header.php.

add_filter('wp_nav_menu', 'my_menu_func');
function my_menu_func(){
print "Testing 123";
}
It worked but it replaced both my top primary menu and the widget side menu.
How can I specify which menu to target when using the filter? | You could try the following code snippet to override the _primary_ menu:
/**
* Override the primary menu.
*
* @param string $nav_menu The HTML content for the navigation menu.
* @param array $args Array of wp_nav_menu() arguments.
* @return string $nav_menu

function wpse_150003( $nav_menu, $args )
{
//Override the primary menu:
if( 'primary' === $args->theme_location )
$nav_menu = 'My new menu';
return $nav_menu;
}
add_filter( 'wp_nav_menu', 'wpse_150003', PHP_INT_MAX, 2 );
where we find the input arguments info from the source.
Notice that we **return** the `$nav_menu` value, instead of **echoing** it.
You could also filter my other attributes, for example `menu_id`.
You might also consider these filters:
* `wp_nav_menu_items`
* `wp_nav_menu_{$menu->slug}_items`

How do I add a featured image to a single post page?
I'm using the Pinboard theme on WordPress 3.9.1. I'd like to edit Pinboard (or, more accurately, make a child theme) so that on single post pages, if the post has a defined featured image, it displays at the top of the post.
I've gathered that doing so requires editing single.php in the theme, but my knowledge of PHP is minimal at best, so when I open single.php, I can't figure out where to make the changes--or, in fact, what changes to make.
Would anyone be willing to walk me through what it would take to include the featured image at the top of a post page such as this one? Once I understand how to properly get the image on the page, I should be able to style it the way I want.
This is probably asking for a little more hand-holding than is normal around here, so big thanks in advance. | In `single.php`, find `<?php the_content(); ?>` around line ~17. Just before that. paste following code.
<?php if ( has_post_thumbnail() ):?>
<div class="featured-image-wrap"><?php the_post_thumbnail(); ?></div>
<?php endif; ?>
This will show featured image if assigned to the post. To change the size of image you can pass parameter to the function `the_post_thumbnail()`. See official documentation of the_post_thumbnail(). I believe you would use child theme for modification. | stackexchange-wordpress | {

<?php
}

</ul> | I have tested your code on my side, and it works perfectly. The relevant info displays, whether I'm logged in or not.
This is definitely not a problem with your code, but more an external problem. You will need to look for any type of code that might restrict this code from showing if a user is logged out, something like `if ( is_user_logged_in() )`. If you have any type of admin/role type plugin, have a look at those as well. They might be restricting a user from viewing certain pages or info when they are logged out
I would suggest the following, get yourself a code editor like Notepad++ and search your wordpress install for statements like `if ( is_user_logged_in() )`. Also look at your user roles and what they can and cannot view if you have customized your roles. You should also try to deactivate your plugins one by one and check if the problem goes away or not. Lastly, try one of the bundled themes.

if beefs id is 37 then i want to retrieve all the posts with `term_id = 37`
Thank's | Have you tried using the WP_Query class? You might find it's easier to use the built-in tools for this instead of a custom query from scratch. Something similar to the following should work for you:
<?php
$args = array(
'post_type' => 'recipe_cpt',
'tax_query' => array(
array(
'taxonomy' => 'recipe_tx',
'field' => 'term_id',
'terms' => 37
)
)
);
$query = new WP_Query( $args ); ?>
EDIT: note the `tax_query` is an array of arrays by design. Many tax query problems are a result of missing this detail.

Find out who deleted a page or post?
Someone moved a very important page on my website into the trash, and I do not know who did it! It was not deleted permanently so I don't need to worry, in that sense.
The revisions, when I restored it, show that someone edited it 3 days prior to today, so it could have been them, but I can't be sure.
Does WP keep track of who clicks the trash button? If not, I presume I'd have to write a custom script to hook onto the trash button, when clicked. | By default, no, WordPress doesn't keep track of who changes post statuses (at least that I can see).
you can hook into `transition_post_status` and log the user id.
add_action( 'transition_post_status', 'wwm_transition_post_status', 10, 3 );
function wwm_transition_post_status( $new_status, $old_status, $post ) {
if ( 'trash' == $new_status ) {
$uid = get_current_user_id();
//somehow or another log the $uid with the $post->ID

Query unique author ids with published post of type job
I'm trying to come up with a simple query to return an array of unique author IDs that have a post_status of 'publish' and a post_type of 'job'.
I know I can query using:
$args = array(
'post_type' => 'job',
'post_status' => 'publish'
);
$published_jobs = new WP_Query( $args );
But this seems horribly inefficient to iterate through the results when all I want is an array of unique author IDs. At most we will have 30 or so authors, but could have thousands of job posts.
Any suggestions? Thanks! | The most efficient means would be to query directly via `wpdb`:
$author_ids = $wpdb->get_col(
"
SELECT DISTINCT post_author
FROM $wpdb->posts
WHERE post_type = 'job'
AND post_status = 'publish'
"

CSV to WordPress posts: do I have to populate each possible field?
I'm planning to import Products in a CSV to WooCommerce.
We are still working on an Excel, and we are using the main fields that a product has, following the WooCommerce wordings for the Products (post_title, post_excerpt, post_content, sku, regular_price, images).
However, we have no columns for ID for example, or comments_status or post_author.
My thinking goes that those fields would be auto-populated by WordPress with a kind of "default", but, hence my question, I'm not sure.
Do I have to include ALL the fields that a Product (or Post or Page) has, so the import is successful?
If so, is it enough to give an ascening ID to the products? (if the last created ID on the site is 35, assign IDs like so: 36, 37, 38, etc).
Thanks for your inputs, | Nope, the WP is pretty flexible about this and will perfectly handling omitted fields. Including assigning IDs (which is actually best left to it, outside of edge cases when exact IDs must be imported).
The only situation that natively won't let you create post is if neither of title/content/excerpt is provided and post type supports any of them. Even then there is `wp_insert_post_empty_content` filter available to adjust the behavior. | stackexchange-wordpress | {

Dynamic meta description
I am trying to make the `<meta name="description" content="">` pull the content from single posts, but I am running into a snag.

It works well but adds the post id in front of the content. Is there anyway to remove that?
Thanks. | The the_ID() function that you are using in your code echos the current post id, to get current post id instead of displaying it use the function get_the_ID() as shown in the following code.
Alternatively you can just use get_post() function without passing any post id as a parameter because the post id parameter is optional and if you don't pass any post id then by default the current post is used.
Try using the following code instead of what you are using.

Get new (not old) post inside transition_post_status hook
Following up the ticket 'transition_post_status' is executed before 'save_post', I'm still struggling how to access the **new** `$post` (after it has been saved) inside a `transition_post_status` hook. Right now, I'm getting the old $post data (before it has been saved).

// a post is getting published
if(!check_my_post($post->ID)){ //how can I get the saved/new post here?
...
// do something
}
}

Any ideas how to achieve this? | According to the Codex, if you use `wp_transition_post_status()` you will get both the old version and the new version.
wp_transition_post_status( $new_status, $old_status, $post )
The ticket also says that the post type needs to support revisions for the save to work.
> Check the post type of the post objects before doing anything.
>
> If your post type supported revisions, you'd see both actions fire twice -- transition then save for the revision, transition then save for the post.

Wordpress does not output "post" class when calling post_class() function
I am writing an ajax call to a server which requests a next set of posts. However when I try to generate a list of posts I am having an issue with post_class() function. It does not add a "post" class to post.

Result:
<article id="post-154" class="post-154 type-post">
Expected result:
<article id="post-154" class="post-154 post type-post"> | `get_post_class()` generates and returns the list of classes echoed by `post_class()`. The only reason for the function itself not producing the result you want can be found in the source `post-template.php`:
if ( ! is_admin() )
$classes[] = $post->post_type;
Which means that the class `post` actually only gets generated if `is_admin()` _doesn't_ apply.
Another possibility actually could be that the filter post_class is used to prevent the class. But given the available information this can just be a non-grounded assumption. | stackexchange-wordpress | {

How to apply action the_post to the post that is only being mainly displayed

function do_some_modifications($post)
{
if (is_singular('product')) {
// do some action
}
return $post;
}
add_action('the_post', 'do_some_modifications');

function do_some_modifications($post)
{
if (is_singular('product') and get_queried_object_id() == $post->ID) {
// do some action

Using a custom field value as current users name

I am a newbie forgive my ignorance!!
Thanks | First of all, you're testing for a string, as you're wrapping `the_field("my_field")` in single quotes. So, you want to remove these quotes. Next, `the_field("my_field")` outputs a field, it doesn't return it. You should try `get_field` instead of `the_field`. | stackexchange-wordpress | {

Using Masonry - How to make every Xth post thumbnail image span multiple columns?
To be specific:
* I'm using Masonry to show all posts within a certain category
* Thumbnail images for each post are shown on the category page in a 3-column format using CSS fluid width columns
* I need to show the 7th thumbnail image spanning the width of all 3 columns

'posts_per_page' => 12,
'paged' => $paged
);

more tag in the $post->content when get_pages were used
I used get_pages() to get the content of the child pages of a page.

This would yield something like:
// Fetch post content
$content = get_post_field( 'post_content', get_the_ID() );
// Get content parts

How to Emulate Default Navigation Menu Behaviour in a Custom Theme?
I'm trying my hand at developing a custom theme, and I've got navigation menus working (with the help of this walker, but only if they're explicitly defined in the menu settings.

If you didn't want to set the global then
$my_comment_ID = apply_filters( 'get_comment_ID', $comment->comment_ID );

How to hook watchdog script for existence of a WP page?
I would like to have a watchdog script which checks the (un)availability of a certain DB entry, namely a certain WP page.
The script itself is absolutely independent from WP and not difficult, but I don't know how where I hook this script into WP. It should be called with every website visit. | An easy way to do this would be to create a simple Must Use Plugin and check for your page in a function hooked to an action, like `wp_loaded`
function wpd_check_page_exists(){
$page = get_page_by_title( 'The Page' );
if( !$page ){
wp_mail( '[email protected]', 'a message from your site', 'the page is gone!' );
}
}
add_action( 'wp_loaded', 'wpd_check_page_exists' );
You may want to use a different function to query the page, depending on how you identify whether it exists or not, like `get_post` if you want to pass an ID, or `get_page_by_path`, or `WP_Query`. | stackexchange-wordpress | {

Adding more onto an esc_url
I have an esc_url that creates a link to buddypress profiles depending on the author of the post which returns like this < I want to make it so it returns "posts" at the end of the url too like so, <
The code I have.
esc_url( bp_core_get_userlink( get_the_author_meta( 'ID' ), $no_anchor = false, $just_link = true )),
I tried placing the following
&& 'posts'
|| 'posts'
after the
bp_core_get_userlink( get_the_author_meta( 'ID' )
and other parts of the code line but my PHP isn't great so I'm not sure exactly how && and || works. Worth a try though. Thanks for the help in advance :) | To concatenate strings, PHP uses the concatenation operator `.`. Thus, to append a string to the current user link, you can use
bp_core_get_userlink( get_the_author_meta( 'ID' ), false, true ) . '/posts/'
Note that I've removed the first part of the assignment from the `$no_anchor` and `$just_link` parameters, as the values should be passed, and not the assignments themselves.
In general, I suggest you start by reading a few basic PHP tutorials. | stackexchange-wordpress | {

Using a private method as an action callback from within a class
I have created a class from within which I would like to call a private method (from within the same class) from the `__construct` method as an action callback.
When I would like to use a public method I can access it by:
add_action( 'init', array( $this, 'action_callback' ) );
However, this causes an error when the method is private. I have also tried unsuccessfully:
add_action('init', $this->action_callback() );
How do I access a private method?
The class looks something like:
class My_class {
public function __construct() {
add_action( 'init', array( $this, 'action_callback' ) );
}
private function action_callback() {
// do something
}
} | It's not possible to call a private method through an action or filter. When calling `add_action` or `add_filter`, WordPress adds the callback to a list of callbacks for that specific action or filter. Then, when `do_action` or `apply_filters` is called, WordPress uses `call_user_func_array` to call the linked functions and methods. As `call_user_func_array` is not called from within the class, it can't call private methods of that class.
Furthermore, there's no proper way to really keep the method private, even though you could add a separate (public) method to your class, add that as a callback to the action, and have that call the private method. In doing that, however, you lose the real concept of the method being private. | stackexchange-wordpress | {

Retrieve a specific field from taxonomy term through advanced custom fields
I've set up a custom field which appears in a taxonomy terms page. I am trying pull an image associated with the custom taxonomy term directly
However the page in which it is being displayed is a template page. I think I need to pass the post ID before pulling the specific image, but how do you do that for a custom taxonomy?
The custom taxonomy is 'manufacture', and the term id is e.g 1, the image field id is 'image_toc' and I have set ACF to image url. I've read the page on "how-to/how-to-get-values-from-a-taxonomy-term/" but I don't really understand what I'm supposed to replace with what. I am using things along the lines of:
<img src="<?php the_field('image_toc', 'I am giving term id here'); ?>" />
But nothing is happening. No image and no path in the source code. | To retrieve a field from ACF for a term (instead of, for example, a post), you should use the taxonomy name, followed by an underscore, followed by the term ID instead of the post ID when calling `the_field` or `get_field`. Assuming you want to retrieve the field `image_toc` for the taxonomy `mytax` and term ID `$termid` that would be:
<img src="<?php the_field( 'image_toc', 'mytax_' . $termid ); ?>" />

Query child's child categories
I'm building a query to get the child's child categories. For example : I have a parent category named 'animal' and others like 'food' and 'sport'. I want to get animal's sub categories.
I do :
$parent_cat = get_cat_ID( $cat_name );
$args = array(
'type' => 'post',
'parent' => $parent_cat,
'order' => 'DESC'
);
$categories = (array) get_categories( $args );
And no problem, with a foreach I get my animal's sub categories.
In my sub categories, I also have categories (this is a 3 levels hierarchy).
I do the same :
$child_cat = get_cat_ID( $sub_cat_name );
$args = array(
'type' => 'post',
'parent' => $child_cat,
'order' => 'DESC'
);
$sub_categories = (array) get_categories( $args );
And... it returns the others parents categories 'food' an 'sport'.
Why that ? Where am I wrong ? | Ok then, I actually was getting the subcats with the wrong method.
in `$parent_cat = get_cat_ID( $cat_name );` `$cat_name` wasn't a name but un slug. First mistake.
So I corrected with `$parent_cat = get_category_by_slug( $cat_slug );`
The final code is :
// Get the parent cat thanks to the page's cat slug
$parent_cat = get_category_by_slug( $cat[1] );
$args = array(
'type' => 'post',
'parent' => $parent_cat->term_id,
'order' => 'DESC'
);
// child cats
$categories = get_categories( $args );
// loop on the child cats to get the sub cats object
foreach ($categories as $key => $value) {
return $value;

Proper Way to Enqueue CSS for Front Page - template_redirect in functions.php?

wp_enqueue_style( 'home_page_style' );
}
}
}
I had come across a blog by Mark Jaquith saying that template_include is for including, which is what I'm doing, right? | Nope. Use the `wp_enqueue_scripts` hook directly for enqueing all styles and scripts. There's no need to hook into `template_include` for that. `template_include` is specifically for modifying templates.

if ( is_front_page() || is_home()) {
wp_enqueue_style( 'home_page_style', get_stylesheet_directory_uri() . '/index-style.css', array('handle_of_main_style') );

Show excerpt for only first post in query
I'd like to only show the excerpt for the first post in my main query. I was wondering the best way to approach this.
What I have tried so far is:
1. Making a custom homepage and using two queries, one that returns 1 post with an excerpt and another queries that returns posts without.
2. Just using the default queries but using css to hide the excerpts for all posts but the first, using `nth-child`.
Both of these work well enough, but I was wondering if there was a better way to do this, through a function or filter.
Thanks! | You can use `$wp_query->current_post` in your loop to check the current post. You don't need two loops, one will do the trick If you need excerpt for first post only, you can do something like this. Just remember, the first post in the loop is `0`, and not `1`
if ( !$wp_query->current_post > 0 ) :
the_excerpt();
else :
<--- DO SOMETHING ELSE FOR OTHER POSTS

Why use while over if in single wordpress posts?
Why is `while()` used instead of say `if()` here:
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', 'single' ); ?>
<?php _s_post_nav(); ?>
<?php
// If comments are open or we have at least one comment, load up the comment template
if ( comments_open() || '0' != get_comments_number() ) :
comments_template();
endif;
?>
<?php endwhile; // end of the loop. ?>
So I've seen this since forever and I've used it too because it's what Wordpress uses by default. However today I'm feeling a bit more curious than usual - why is while used instead of if ? Am I expecting to receive more than a single post in single post view ?
< < | As the WordPress Codex for `have_posts` points out:
> As a side effect, have_posts starts, steps through, or resets The Loop. At the end of the loop, have_posts returns 0 after calling rewind_posts.
Looking at the source as it stands today: along with calling `rewind_posts()` it also fires the `loop_end` action (which plugins may rely upon) as well as set a flag so `in_the_loop()` correctly returns false afterwards.
So calling `have_posts()` on each iteration does more than just return a Boolean. I wouldn't lean too much on the specifics of the source because that's a moving object. It's enough to understand that there are other housekeeping tasks performed when you call `have_posts()` until it returns false and you're less likely to introduce subtle interoperability issues if you use it that way even when there is only a single post involved. | stackexchange-wordpress | {

Copying database tables to new database

How can i can copy this correctly ? | Export your tables using phpmyadmin interface. Just select those tables only that you want to export from the old database and import those tables in the new database

Difference between the_permalink() and get_permalink() function
In WordPress I am using both `the_permalink()` and `get_permalink()` functions, but I cannot get any difference in the output of both functions. What is the difference between both functions? | `the_permalink` echos out the permalink of the current post to the frontend.
`get_permalink` however returns it as a variable, but does not echo it out. You can also pass a post ID to it if you want the permalink of another post.
`the_permalink` is equivalent to:
echo get_permalink();
Which is very close to what it actually does. This is the implementation of `the_permalink`:

Checking for existence of a page by title?
I'm currently working on a plugin, and I essentially want to check if a certain page has been created.
Essentially, I want to do something like this:
if (file_exists($file)) {
$exists = true;
} else {
$exists = false;
}
But I just want to do it so that it checks, instead, for a post_name value. (If I was further able to ensure that the post was a _page_ and not just a post with that title, that would be great too.)
How do I do this?
I had been getting the script to grab the headers from the url of the post and if it returned a 404, to return $exists = false, but I've pinpointed a memory leak problem with that and I don't think it's very efficient. | Using `get_page_by_title()` along the line of below exemplary code should work:
if ( get_page_by_title( $page_title, $output, $post_type ) == NULL ) {
$exists = false;
} else {

}
_Explanation:_
* `$page_title` is obviously what you are looking for;
* `$output` can be OBJECT, ARRAY_N or ARRAY - Default: OBJECT;
* `$post_type` can be specified, in your case its not needed, because the default value is `page`;
* Returns `NULL` if no post with the title is found;
* For the inner logic take a look at the source. | stackexchange-wordpress | {

How to get the slug of the homepage when editing it in WP admin?
According to the WP_Class reference, `$post->post_name` holds the value of the slug of the current page being viewed. If I'm currently viewing the WP admin edit screen for my homepage as set under Settings > Reading > Front page displays > A static page > Front page, what would be the value of `$post->post_name` if I do the following?
global $post;
echo $post->post_name;
I wasn't aware my homepage had a slug. Would the value be an empty string? Hoping someone can help clarify. Thanks in advance. | `post_name` would be the slug as it was set before the page became the front page. When the URL for the front page is output via the API, the `get_page_link` function checks if the ID matches the `page_on_front` option and returns the `home_url` in that case. This is why you should always use the API to output data and not directly access post object fields. | stackexchange-wordpress | {

Modify text after post count
On my Archives page, I list categories with post counts. I've modified the post count by removing the parentheses, wrapping them in a span that floats them to the right, and putting the word "Entries" after each post count. But I'd like the text after the count to change for categories with only a single post (i.e. "Entry" instead of "Entries").

$variable = wp_list_categories('title_li=&echo=0&show_count=1');
$variable = str_replace( '(', '<span class="cat-count">', $variable);
$variable = str_replace( ')', ' Entries</span>', $variable);
echo $variable;
?>
How can I modify this so that categories with 1 post say "1 Entry" and those with more than 1 say "X Entries"?
You can see my Archives page here | The `_n()` function will sort out single from plural. How to use it is in the codex.
**EDIT:** Apologies. My first go at an answer wasn't quite enough to get you there. The trouble with using `wp_list_categories()` in this context is that it prints out pre-formatted HTML and you don't end up with any value you can use for $count.
Instead, try using `get_categories()` which will return an array of category objects you can tap into to get post counts and display accordingly.
Something like the following should do the trick, or at least get you started:

$categories = get_categories();
echo '<ul>';
foreach($categories as $category) {
echo '<li><span class="cat-count"><a href="' . get_category_link( $category->term_id ) . '">' . $category->name.'</a>';

Using get_query_var() from a plugin

* i'm using it inside of `init` hook set as priority 999
* it works if i use `wp_head` instead of `init`, but this way i can't do the redirect anymore
* i flushed rewrite rules

Reason: `init` is too early, query_vars haven't been set yet. `wp_head` is too late, no can redirect at that point. | stackexchange-wordpress | {

Getting Term_id - Taxonomy Metadata plugin
I've been looking everywhere but can't find any way to make this works. I am using the Taxonomy Metadata plugin and I am trying to display the custom metadata created. For this I use: `get_term_meta($term_id, 'my_metadata', TRUE);`. The problem is that I can't find a way to get the term_id. I am in a template page inside the loop. Here is what I have tried:
$term = get_term_by('name', 'name', 'custom_taxonomy');
$termid = $term->term_id;
$metadata = get_term_meta($termid, 'my_metadata', TRUE);
But it's not working, it just returns: `Trying to get property of non-object` for the term_id.
Could you help me please?
Thank you! | Alright, I have found a way. If it can be useful for someone here is how I solved it:
$terms = get_the_terms( $post->ID , 'custom_taxonomy' );
if($terms) {
foreach( $terms as $term ) {
$term_id = $term->term_id;
}
}
Then you can use `$term_id` in your expression. | stackexchange-wordpress | {
