Word limit in post_content after more tag
I am using the following code to hide the teaser and show content only after more tag in loop:
<?php
$after_more = explode(
'<!--more-->',
$post->post_content
);
if( $after_more[1] ) {
echo $after_more[1];
} else {
echo $after_more[0];
}
?>
Is there anyway to show only first 50 words instead of entire post content? I want to hide teaser and show 50 words after tag. | Use `wp_trim_words` function to limit the content to a certain number of words and returns the trimmed text. Example use of `wp_trim_words` function.
<?php
$content = get_the_content();
$trimmed_content = wp_trim_words( $content, 50, NULL );
echo $trimmed_content;
?>
So I added `wp_trim_words` function in your code to get 50 words after `<!-- more -->`.
<?php
$after_more = explode( '<!--more-->', $post->post_content );
if( $after_more[1] ) {
$content = $after_more[1];
} else {
$content = get_the_content();
}
$trimmed_content = wp_trim_words( $content, 50, NULL );
echo $trimmed_content;
?>

Change date from 2015/02/23 to "1 min ago"
So here is my code to display the post created date:
$date_create = '<div class="mydate-created">';
$date_create .= get_the_date('',$product->id);
$date_create .='</div>';
$output .= '</div>';
$output .= '<div class="mydate-created">';
$output .= get_the_date('',$product->id);
$output .= '</div>';
It displays the date of post created as the following "2015-02-23"
I know there is setting in the backend to change the date displayed.
However is there a way to display it like "1 min ago" or " 1 hour ago"?
Thanks! | Here you go. This goes in `functions.php`
This changes the time on your website everywhere. Now you can keep using `<?php echo get_the_date(); ?>` in your loop or theme files.
// Relative date & time
function wpse_relative_date() {
return human_time_diff( get_the_time('U'), current_time( 'timestamp' ) ) . ' ago';
}
add_filter( 'get_the_date', 'wpse_relative_date' ); // for posts and pages
// add_filter( 'get_comment_date', 'wpse_relative_date' ); // for comments
I added a PHP comment before `add_filter` to also change comment dates too. Because I am not sure if you want that for comments too. Remove PHP comment if needed. | stackexchange-wordpress | {

Get only one product category woocommerce
I have to get and show only one category name from a product. I have almost read everything and tried everything.
<?php
$term = get_the_terms( $post->ID, 'product_cat' );
foreach ($term as $t) {
$parentId = $t->all;
if($parentId == 0){
echo $t->name;
}else{
$term = get_terms( 'product_cat', array('include' => array($parentId)) );
}
}
?>
It shows one long string with all the category names. How should I get only one category and show its name. | Before I begin, just one note, there is no property called `$all` in `get_the_terms`. Here are the available fields which you can use
stdClass Object
(
[term_id] =>
[name] =>
[slug] =>
[term_group] =>
[term_order] =>
[term_taxonomy_id] =>
[taxonomy] =>
[description] =>
[parent] =>
[count] =>
[object_id] =>
)
I'm not very sure what you want to achieve looking at your code, but if you need only one term from the returned array, you can do something like this: ( _NOTE:`get_the_terms` returns a `WP_ERROR` object on invalid taxonomy, so you want to check that, also check whether or not you have terms retrieved_)
$terms = get_the_terms( $post->ID, 'product_cat' );
if ( $terms && ! is_wp_error( $terms ) ) {
echo $terms[0]->name;

How do I turn off the blog and archives?
Is there a fixed set of htaccess rewrite rules I can use to "turn off" everything blogging related?
It's not enough to just not show the links in the menu, I want to completely hide everything related to the blog part, including blog posts, archives, tag and category pages. So people or robots can't come across it by guessing the url or though the sitemap.xml In other words just use WP as a CMS for a website. | You are already using pages which does not work the same as posts.
You have to remember, pages don't have taxonomies and they are excluded from the main query by default on all archive pages and the homepage, so there can never be any links to any kind of archive.
Archive pages, whether date, category or tag archives, are just dummy/virtual "pages" which does not exist. Archive pages are just a way to group posts together which shares a common object. If a grouping object does not exist, the archive page can never exist
To conclude, there will be no links to archive pages that can be "guessed" by robots or humans, it is as I said, they will never exist. Links that does not exist will never be indexed anyway.
And any link in a site that does not exist will simply 404, it will not display blank pages | stackexchange-wordpress | {

error_log over 70GB. How to stop this?
I just migrated a website from a host to another. And in one day, my error_log got up to 70GB. How to stop this? | Most important thing here would be to figure out what's causing the errors as opposed to just hiding them. 70 GB file might be tough to open, so you can use tail to open up the last several lines of it `tail -f error.log` and see what's going on. Maybe it's a quick fix.
If it's filling up with notices and things you're okay with you might have debugging turned on? Turn it off in wp-config:

Genesis - Adding custom hooks to display secondary navigation

pre_get_posts having no effect on my category archive

function filter_archive( $query ) {
if ( ! is_admin() && is_category('76') && $query->is_main_query() )
$query->set('posts_per_page', '12');
}

Overwriting templates in child theme and performance

Is this bad for performance or the incorrect way? | Actually, what you have described is the correct way to do things and there shouldn't be any noticeable impact on site speed and performance.

Site needs massive upgrade - how to proceed?
I have a former customer who, contrary to my recommendations, has not stayed on top of their WP upgrades. They now need to make the leap from 3.5.1 to 4.1.1 (or whatever is current at the moment). They used a fairly vanilla theme (might have even been Twenty Eleven), and not used too many plugins.
I have found numerous threads (here and elsewhere) that talk about doing this 1 mini-upgrade at a time. Is this really necessary, or can bigger steps be taken? E.g. 3.5.1 -> 3.9, then 3.9 -> 4.0, and then 4.0 -> 4.1.1
Thoughts or experiences are appreciated. | Check out the Codex on Upgrading Across Multiple versions.
Regarding the upgrading steps, it says:
> If you plan on upgrading across more than two major releases, please consider upgrading incrementally to avoid potential conflicts and minimize the risks of database damage. For example, if you plan on upgrading from 2.5 to 4.1.1, upgrade to 2.7 first, followed by 2.9, then 3.1, and so on. Essentially, it's okay to skip one release, but never skip TWO when upgrading.
So according to this advice, your upgrade sequence could be:
3.5.1 -> 3.7.x -> 3.9.x -> 4.1.1
I agree with the comments by @Milo and @PieterGoosen; You shouldn't experiment with this on a production install, test this first on your dev install. Deactivate plugins before the upgrades and activate them afterwards, one at a time. Remember to activate the debug log and scan through the `debug.log` for errors.
Remember to backup everything.

Excerpt for pages not showing

function my_add_excerpts_to_pages() {
add_post_type_support( 'page', 'excerpt' );

Get the post thumbnail with wp_query

Any suggestions would be great. | If you are using this inside the loop of your `WP_Query` then why are you providing the `Post ID` parameter in functions. You don't need to do that.

Schedule Page to Menu
Every week I tend to have 2-4 pages scheduled though I need to get them added to my menu as well.
The "Add New Top Level Pages to Menu" option won't work in my case though as the pages in question aren't top level. In odd cases they're subpages of subpages.
Does anyone know of any way to schedule pages to add to a menu with or without a plugin? I would try and code one in but it's a little too complicated for me.
I posted this exact question on the WordPress support forum and it's gone unanswered for too long, hoping for some answers here.

Here is also a link to the author's site, < , where he discusses why he built the plugin and also two other plugins that also work similarly. The advantage of the Jamocreations Auto Submenu plugin though is that if later you want to edit the menu using Wordpress Menu editor the entries are actually visible there so you can reorder them or whatever.
The plugin works based on selecting a parent page from the Wordpress page editor. If the parent page or parent sub-page has been added to the Wordpress menu, then its child pages will automatically be added as well. | stackexchange-wordpress | {

How do I set a specific template for sub-categories?
There's a few posts about getting sub-categories to use the same template as their parent but I want to do something slightly different.
I have a category 67, and I want all sub-categories of 67 to use a specific template. Not the default template, and not the custom category-67.php template.
How do I do that?
I have the following code in functions.php, but it also seems to change the template of category-67
// use specific template depending on category
function myTemplateSelect() {

load_template(TEMPLATEPATH . '/category-slider.php');
exit;
}
}
}
add_action('template_redirect', 'myTemplateSelect');
Eventually I will want to add a few more categories to this also.
Any ideas?

Thx. | If you look at the source of `add_settings_error()`, you will see that the errors are stored in the `$wp_settings_errors` global. So in your `tearDown()` function, you can do this:

301 Redirect Loop
I have wordpress site hosted on openshift say example.com. I am redirecting example.com to www.example.com (non www to www). I have created alias for www and non www version and updated my cname with app name.

I need a lightbox plugin that will apply to gallery

How to use the built in tooltip for form validation error messages in WP admin plugin?
I'm building a wordpress plugin that includes serveral menus in the wordpress backend (admin). I'd like to use as many existing parts as possible and make my menus look like the standard wordpress ones.
Wordpress already does quite nice form validation on its admin forms and I already reuse the `form-required` class to enforce required form fields.

Can somebody provide a hint on how to reuse this from a custom jquery form validation script?

Set Display Name to first and last name (phpmyadmin SQL Query)
I'm trying to change all the users Display Names to be their first and last name. I have looked into a number of plugins and wrote my own PHP to try and accomplish this however the site has over 50,000 registered users (I can imagine most are spam from my clients previous site) but because of this the PHP hangs and only gets to about 2000 before giving up.
So I thought that the next best thing would be to write an SQL statement from within PHPmyAdmin to perform the task, However pure SQL confuses the hell out of me and so far all I have been able to do is set the display name to be the users First name I'm not to sure how I would go about getting the Last name as well. Here is the statement that I used.
UPDATE wp_users, wp_usermeta
SET display_name = meta_value
WHERE ID = user_id
AND meta_key = 'first_name'
Any help would be appreciated. | I know this is an old question, but for anyone still looking how to achieve this, the following query should do the job:

SET wp_users.display_name = CONCAT(fn_meta.meta_value, ' ', ln_meta.meta_value)

Why the WP Core team does not allow filter_* functions?
This question is somehow related to this other question.
Provided that is seems we have a solution for the magic quotes issues, why the WP Core team does not allow them?

* Apparently the issue has been rones by @westonruter: <
* This post from @westonruter actually looks like to be positive: <
As far as I can see, filter_* functions are the best way (even better than WP core functions, in my opinion) to handle validation, filtering and sanitation. Also, they are part of PHPNG (therefore, PHP 7) and everywhere I can see posts saying to use these functions (here in SO, as well as elsewhere). | Because on the minimum version required it isn't always available since the SPL can be disabled on PHP 5.2 and below.

date_query not returning some posts in date range

I also suspect that your problem might be related to PHP and not Wordpress.
Your `before` date is invalid. PHP only supports dates between 13 December 1901 and 19 January 2038, so your dates need to between those two dates. For reference, see `date`

Migrate WooCommerce Orders
I need to export/import all WooCommerce orders from a clients old website to their new website. We basically took their website, redesigned it but the install and everything is the same - besides there being two versions and both are on different servers. We tried replacing postemta and posts but that messed up EVERYTHING, like the pages, menus, etc.
We are on a tight deadline (every moment is crucial) and we need help on this. We are aware of the plugins, but if there is a dirty way to do it we are open to it.
To reiterate: we need to move just the orders from one site to another without messing everything else up.
Thanks in advance! | The reason copying those messed up your site was probably because of id mismatches. That is, posts with the ids of the stuff you're importing already exists.
Regardless, since woocommerce stores orders as a custom post type, your safest bet here is probably the built in wordpress post import/export tool.
1\. In the wordpress backend for the old site select Tools->Export
2\. Choose "Orders"
3\. Download the export file.
4\. In the wordpress backend for the new site select Tools->Import
5\. Click "Wordpress" (install the plugin if you need to).
6\. Choose/Upload the file you created in step 3.
If you need to do this through SQL for some reason, the place to start will be with
`SELECT * from wp_posts WHERE post_type='shop_order'`
Then you'll need to export the result of that query and increment all of the IDs by whatever the auto increment value is on the new table. But that will give you a pretty messy table... | stackexchange-wordpress | {

Can A Post Meta Field Store multiple values that are not in an array?
I have a post_meta field that seems to be displaying multiple values, yet they do not seem to be in an array. Using debug bar, this is what I see inside of the '_custom_post_type_onomies_relationship' meta field.
!screenshot
I want to filter these id's to return titles instead. Because I am using Facet WP, I need the values to NOT be an array when done.

$title = get_the_title( $item_id );

}

This works just fine except that it is an array. What data type is that custom field before I filter it? How do I reproduce that data type?
Note: Before I filter it, the data type must not be an array because FacetWP can understand it. | Meta data keys do not have to be unique, you can have multiple rows of the same key, each containing singular values. If you use `get_post_meta` to fetch a key and don't set the 3rd argument to `true`, the function gets all the individual values and returns them as an array, which is not the same as getting a single value that is an array saved as a serialized string.
If you want to iterate over the returned array and save new values, you have to call `update_post_meta` for each item in the array, and set the 4th argument of the function, which is the old value of the particular row you'd like to update.
$item_array = get_post_meta( $post->id, '_custom_post_type_onomies_relationship' );
foreach ( $item_array as $item_id ) {

Filtering the default avatar list
I'm using the `avatar_defaults` filter hook to filter the default avatar list. For example:
function my_avatar_defaults( $avatar_defaults ) {
$avatar_defaults[' = __( 'Foo' );
return $avatar_defaults;
}
add_filter( 'avatar_defaults', 'my_avatar_defaults' );
This works because if I visit Settings > Discussion and then scroll down, I can see Foo has been added as a default avatar option. See the following screenshot for an example:
!Default avatar list of options
The problem is the `src` attribute of the image displayed next to Foo. It seems to be making a call to Gravatar. Here's an example of the source code I'm getting for the image next to Foo:
<img src=" />
How can I ensure the `src` attribute points to my image URL instead of the Gravatar URL (which seems to have my image's URL inside it)? | You are doing it correctly.
The call to gravatar.com passes the location of your custom image so that WP can load it. Take a look at the query string in the src, you'll see your image location. That's how it works. | stackexchange-wordpress | {

How to order by multiple fields using standard query_posts?
In our `archive.php` we show all the items which match our selected category. This works absolutely fine.
Then we improved it by adding (just before the loop) a sort and upping the posts per page from the default 10, like so:
$posts = query_posts($query_string . '&orderby=title&order=asc&posts_per_page=99');
This works even better.
Now, however we want to sort by more than one field, say `menu_order` then `title`. I don't see a way to do this using this query_posts / querystring syntax we have in place. Code samples all involve firing up a new WP_Query, losing track of the query_string. What's the solution? | If you're altering the main query, always use `pre_get_posts` to alter query parameters _before_ the query is run and before the template is loaded. This will be the most efficient and will not break pagination. As of v4, `orderby` accepts an array of arguments, which gives you the ability to have different `order` for each if necessary:
function my_get_posts( $query ){
if( !is_admin() && $query->is_category() && $query->is_main_query() ){
$query->set( 'posts_per_page', -1 ); // show all posts
$query->set( 'orderby', array('menu_order' => 'ASC', 'title' => 'ASC') );

Plugin installation not possible / FTP credentials in WP-config

Difficult to create unique titles and meta description?
I have just made my first theme for WordPress and I have been searching for information or some kind of tutorial, about how to create some sort of very simple plugin to handle unique titles and meta description for the pages and blog posts.
Is this very complicated? Where can I find info about this?

Most likely. If you're using WordPress 4.1, make sure there is **no** `<title />` in your `header.php` and add the following to your `functions.php`:
add_theme_support( 'title-tag' );
Otherwise, make sure the title tag looks like:
<title><?php wp_title( '' ) ?></title>
You should also have `<?php wp_head() ?>` within your `<head />`, this allows WordPress & other plugins to kick out all sorts of stuff to function correctly. | stackexchange-wordpress | {

Getting Plugin to read all script files
In my pluging I created a file-1.php file which contains the plugin info and some functions for the plugin functionality, when the file was getting too long, I created a file-2.php file and put some functions there, my plan is to organise the plugin into several logical files, but the plugin could not process the functions in file-2.php, untill I `include("file-2.php")` in file-1.php, which is more or less having one long file-1.php
I thought plugins would be able to read functions from any file without the _include_ directive.
Does the plugin info written in the first file gives it special privilege/priority? | Plugins, like any other functions file in a theme are just extensions to your theme's functions.php file. Any file that extends the main functions.php has to be manually included into the main functions file. The reason for this is, only files and templates within Wordpress file structure gets auto laoded. There is no logic to regocnize and to include custom files or templates
The main plugin file of a plugin however is autoloaded and need not to be manually included, although it is just an extension to the main functions.php file of your theme. A plugin is identified by the header of the main plugin file, and it is this header that wordpress uses to identify the plugin and according to that auto loads the main plugin file.
Again, Wordpress only loads the main plugin file as it only knows this file. Any extension to the main plugin file is ignored as Wordpress don't recognize it. To get Wordpress to load any other files, you need to include them into the main plugin file | stackexchange-wordpress | {

Is it a good practice to disable wpautop for premium themes?

Also, Is there any way to fix formatting with disabling wpautop ?

The simple truth is disabling wpautop pretty much breaks the line spacing in the visual editor, and if your clients are going to want to use the visual editor, which most of them do.

get_post_types not working properly in admin
I'm trying to get all post types (custom & built_in) but it's only gives me only built_in ones in admin. I can get all of them in root (5 with builtins included) but in admin, i can only get 3.
I throught need a trigger an action or something but i couldn't find it.
$post_types = get_post_types( array( 'public' => true ), 'name' );
var_dump($post_types);
More info: I'll use it in reduxframework's config page (in "setSection" function).
PS: I don't want to get post_types with sql query, because i need empty post_types too.
Edit: it is not about just admin.
For reduxframework developers; you can't use any function which uses the `init` action flag. For reference: < | `register_post_type` is recommended to be used in `init` action hook. So, `get_post_types` should be used in an action after `init`. Hooking in `init` with a very high priority, 999 or greater, should also work in almost every situation but it is safer to use a later action hook.
Example:
add_action('wp_loaded', function(){
$post_types = get_post_types( array( 'public' => true ), 'names' );
var_dump($post_types);
});
In admin section you can use `admin_init`, which run after `init`:

$post_types = get_post_types( array( 'public' => true ), 'names' );

Do rewrites added with add_rewrite_rule() persist after plugin deletion?
I am developing a Wordpress plugin and need to ad a rewrite url using `add_rewrite_rule()`.
That does work. But what happens when my plugin is deleted? Does Wordpress cleanup the htaccess or do I need to do that? How can I remove a url which was added using `add_rewrite_rule()`? | Let me say beforehand that when using `add_rewrite_rule()` nothing is written to the htaccess file. Rewrite rules are stored in the database and handled by WordPress internally on PHP level.
**TL;DR:** Rewrite rules do persist after plugin deletion, but probably not the way you'd expect it.
When using `add_rewrite_rule` these rules are added in the options table in the database. You then need to flush the rewrite rules via `flush_rewrite_rules()` (Visiting Settings > Permalinks and saving does the same) for them to come in effect.
Similarly when you remove your plugin that added the rewrite rules they stay in effect until the next flushing of the rewrite rules. So yes they persist, but they will disappear at some random point later on when the rewrite rules are flushed. | stackexchange-wordpress | {

Including 2 Negative Is_Template Conditionals in header.php
I want to set a conditional in `header.php` to wrap all of my templates, except `front-page.php` and `single-device.php`, in a bootstrap container element.
Writing one conditional achives what I want
if( !is_singular('device') ) {
echo '<div class="container">';
}
However, when including two conditionals, only the first conditional applies.
if( !is_singular('device') || !is_front_page() ) {
echo '<div class="container">';
}
Is the logic incorrect? | _(Expanding on Pieter's comment above, and explaining the logic behind it...)_
`if()` evaluates the conditions in the parentheses, and that evaluation results in either `TRUE` or `FALSE` for the sum total (which can change, depending on how the various conditions are combined).
In plain English, `if( !is_singular('device') || !is_front_page() )` means, "If it's _either_ true that this is not a single Device post, _or_ true that this is not the front page, then..."
Since a URL on a WordPress site isn't going to both be the front page and a single post (unless you've gone out of your way to configure it as such, I suppose), you probably want to use `&&` instead: `if( !is_singular('device') && !is_front_page() ){}`
In plain English, the latter `if` statement means, "If it's _both_ true that this is not a single Device post, _and_ true that this is not the front page, then..." | stackexchange-wordpress | {

How would I change it to html php format? (I am not sure if I am asking it correctly). For example, I tried to change it but I am not sure if it is correct:

<a href="<?php $userpro->permalink($post->post_author); ?>"><?php echo get_the_author_meta('display_name', $post->post_author);?></a>
</div>
Did I do it right?
Thanks | First thing's first, we need to get our globals. If you're in The Loop you can remove the `global $post` in my code, if you're outside The Loop `$post` may not be what you expect it to be. We'll always need the `global $userpro` though.
<?php
global $userpro,
$post;
?>
<div class="myrelatedauthor">
<a href="<?php echo $userpro->permalink( $post->post_author ); ?>">
<?php echo get_the_author_meta( 'display_name', $post->post_author );?>
</a>
</div>
The key differences between your code and my code is that I include `global $post` and `global $userpro`. I also `echo` out the value returned from from `$userpro->permalink()`. | stackexchange-wordpress | {

CTP - check for value inside objects
I have registered a CTP which can add a new plant and user can tick which months it can be planted (february, march and april for example). Now, I need to display it on the page but with all months listed starting from the first one. For example january: no, february: yes, march: yes, april: yes.. december: no.
The problem I am facing is that with `get_the_terms` i get an array with many objects, and I am not sure how to check if value (in any of the objects) is equal to the name of the month.
$months = array('january', 'february', 'march'....);
$terms = get_the_terms( $post->ID , 'myctp' );
foreach($months as $month) {
foreach($terms as $term){
if($month== $term->slug)
echo 'yes';
else
echo 'no';
}
}
This doesn't work good because of the nested foreach loop, it will double/triple... data for each month if more terms are present. | There's no need for two loops. Just iterate over the terms and use `in_array()`:
foreach ( $terms as $term ) {
if ( in_array( $term->slug, $months ) {

Unrestricted height thumbnails
I have set my default thumbnail size in settings > media, however as I see it you _Have_ to add a value. However, I'd like to specify a width, but allow for an unrestricted height. For instance, both these dimensions would be alright:
w: 120px h: 70px
w: 120px h: 240px
Doesn't Wordpress allow this behaviour? Or should we simply set the height value to a ridiculously high number? | According to `add_image_size()` you can do something like that with `width` but I imagine it works the same with `height`:
> **$width**
>
> (int) (optional) The post thumbnail width in pixels. **Set to 9999** to resize based on $height Default: 0
Really I think you would want to set it to something ridiculously high which 9999 should work for you. You could test this and use a plugin like Regenerate Thumbnails to try it out or revert your changes if it doesn't work. | stackexchange-wordpress | {

How can I get a page url knowing only its ID? | You're probably getting that error because WordPress doesn't have the $wp_rewrite global loaded yet for some reason. Either something deactivated it, or you're trying to run those functions before WordPress has a chance to load it.
If you're trying to do this in a plugin or in your theme's functions.php file, make sure you're inside a function that is hooked to after_setup_theme or a hook that runs sometime after. For example:
function get_url_of_page_id_165() {
return get_permalink( 165 );

Rendering css to screen and debug problem

so the question is, what is the problem ? the CSS, the browser, the debugger the system (mac?) or HTML... if need your light !... thanks in advance | Its an old bug in Chrome.

Which template name to use for taxonomies but not their terms?
I can't figure out which template name to use to modify custom taxonomy archive page, but not the one for terms in that taxonomy.
My goal is to show terms list in custom taxonomy archive and in custom taxonomy terms - custom post types..
`{taxonomy}-{term}.php` is used to display custom taxonomy terms ( so there will be custom post types inside ) but i need so there would be terms list inside.
Hope my question in clear.
## Edit:
Just found out that I can't open that kind of page in wordpress at all.. So now question is how to make such page?
For ex. I have ct - `device`. So `/device/iphone` will show all posts in `iphone` term, but `/device/` should show all terms in device tax.
My problem is that `/device/` is readed as page slug, not tax in wordpress by default.
How to change that? | There is no such hierarchy in Wordpress, accessing a custom taxonomy directly simply `404`. This works for all taxonomies, build-in or not. There is unfortuantely no other work around to this but to create a page
You should create a custom page template with a custom query to list your taxonomy terms, something like the following
* Create a page template called `page-device.php`
* Use `get_terms()` to create your list, something like this: ( _Extend as needed, taken from the`get_terms()` page_)
$terms = get_terms( 'device' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
echo '<ul>';
foreach ( $terms as $term ) {
echo '<li>' . $term->name . '</li>';
}
echo '</ul>';
}
* Create a page in the back-end with slug `device`
Now, if you visit `mysite.com/device/`, you will see this page showing up with all your terms in the taxonomy `device` | stackexchange-wordpress | {

How to get image extension from wp image editor object?
`get_extension` seems to be a protected method dunno why, seems to me there is no way to get file extension using image editor object...

$wp_img->save($save_path);
$img_name = basename($wp_img->generate_filename('suffix'));
$img_name = str_replace('-suffix', '', $img_name);
$img_url = content_url() . '/tmp/' . $img_name;
$filepath = WP_CONTENT_DIR . '/tmp/' . $img_name;
As you can see a suffix must be specified because currently the method adds a default suffix as the image size by default, and to retrieve the correct image filename + extension it must be removed afterwards. | stackexchange-wordpress | {

Enqueuing scripts and styles in custom plugins
I have a couple of questions regarding enqueuing scripts and styles in custom plugin code.
I've recently come across plugin code where scripts were enqueued hooing into the `template_redirect` action hook while scripts were enqueued using the `ss_css` (I guess this is a custom action) and `login_enqueue_scripts` action hooks.
My question, therefore, is:
What is the most appropriate hook to enqueue JS scripts and styles. Is it `wp_enqueue_scripts` as is the case in themes? Or should it be more purpose specific as in the scenario described above? In short, should enqueuing scripts and styles in plugins be governed by different rules? | Straight outta the Codex:
> `wp_enqueue_scripts` is the proper hook to use when enqueuing items that are meant to appear on the front end. Despite the name, it is used for enqueuing both scripts and styles.
So the simple answer to your question is yes, `wp_enqueue_scripts` is always the correct action for enqueuing scripts AND styles. This is so other themes/plugins can modify previously-enqueued files or other plugins (e.g. a minifier) can assume that all scripts/styles are loaded with that hook. | stackexchange-wordpress | {
