Template hierarchy override
One of the best way to override the default template hierarchy is to use the child theme and copy and paste the template file (from parent theme to the child theme) you want to override and change the code of the template file according to your need (to display the content on the template page). The other way is to use filter ( `add_filter( 'template_include' , 'custom_template' , priority_value );`) to bypass the predefined structure of template hierarchy.
Can any body explain how the second method works in detail? | To understand how this works, take a look at the source file `template-loader.php`. Here you see several lines of statements which determine which template WordPress will load. Near the end is the filter, which allows you to undo all the previous lines.
For instance, one of the lines determines which template to load if `is_single` is true. You could use the filter to add extra conditions, for instance to load a different template if `is_single` is true and the post is in a certain category. Beware, this still means you would need to have a template file in your child theme (where you also have the filter in `fucntions.php`).
Basically, for all templates that WordPress can find through the conventional naming of the template hierarchy, it doesn't make sense to use the filter. You would only use it if very specific conditions apply under which the template must be called. | stackexchange-wordpress | {

How to use add_action('wp_ajax_[action name]',...) for a specific page with condition?

... <- initalize $this->editable_item->item
add_action('wp_ajax_foo',array( $this->editable_item->item, 'foo' ) );

if( isset( $_GET["page"] ) && $_GET["page"] === 'edit-foo' ){
add_action( 'admin_init', array($this, 'init') );

Switch position of elements in the footer

How to Create a Multi Purpose Theme?
I keep Seeing the new themes on themeforest comes with multiple layouts i mean they are multipurpose theme. how can i create a multipurpose theme having 7 different layouts, how could i connect them what are the functions?? | The way I do it is create multiple layout files, add the option to choose which one to use on the template options panel:
layout-left.php
layout-right.php
layout-both.php

<?php get_header(); ?>
<?php if( get_option_tree( 'mz_layout' ) == 'right') { ?>
<?php get_template_part( 'layout', 'right' ); ?>
<?php } else if( get_option_tree( 'mz_layout' ) == 'two') { ?>

After changing Site url to https, can't access login page

Just login to cpanel or just use ftp. Then createa folder inside wp-content named mu-plugins .
Now download that plugin and upload all files of that plugin in mu-plugins folder. Make sure there is no folder inside mu-plugins folder. Just upload the plugin files to mu-plugins. Then this plugin will be active automatically and your problem will be solved right away.

Clean Custom URL for Serach + Custom Taxonomy
I have a custom taxonomy, called `filter`. All of the following urls lead to the `archive.php` and should give me at least 1 post.
* `/filter/bar` works by default, no custom rule needed
* `/myCategory/filter/bar` works with my own custom rule, nice!
* `/search/foo` works by my custom rule
* `/?s=foo&filter=bar` works as expected
* **`/search/foo/filter/bar`** **BOOM!** No entries
Here are my rules:
add_filter("rewrite_rules_array", function($rules) {
$newRules = array();
// ... more rules
$newRules["search/(.+)/?$"] = 'index.php?s=$matches[1]';
$newRules["search/(.*)/filter/(.*)/?$"] = 'index.php?s=$matches[1]&filter=$matches[2]';
$merged = array_merge($newRules, $rules);
return $merged;
});

**EDIT**
Query-Monitor for the desired URL (suche = search in german)
![enter image description here]( | With Slam's kind tip to use query-monitor plugin, I could figure out what the problem was.
Apparently the url `/search/foo/filter/bar` also fits the "general search" rewrite-rule. Makes sense, thinking about it– `(.+)` technically matches `/foo/filter/bar` aswell. So I could improve `(.+)` by excluding `/`s?
But I found an easier solution!
In hope "first match wins" I declared the more specific rule before the general rule– and e voila, it worked!
add_filter("rewrite_rules_array", function($rules) {
$newRules = array();
// more specific rule first
$newRules["search/(.*)/filter/(.*)/?$"] = 'index.php?s=$matches[1]&filter=$matches[2]';
// general rule later

Note there asome pages which look alike, maybe I can create catogories, but is it possible to select part of the content and put it in a div for example? | WordPress is fetching current post for you, you have to only type to the right url. When you get e.g. to `example.com/lorem-ipsum/` WordPress will load automatically post with title `Lorem ipsum` and display it using `page.php` template. Your `page.php` template should be looking something like that.
<?php get_header(); ?>
<div id="content">
<?php while ( have_posts() ) : the_post(): ?>
<h1><?php the_title(); ?></h1>
<?php the_content(); ?>
<?php endwhile; ?>
</div>
<?php
get_sidebar();
get_footer();
The concept of a loop is difficult to understand for novice developers. Only in the loop you can use functions like `the_title` or`the_content`. Outside of the `loop`, these functions won't return you anything.

Insert wp_query after the_content with plugin (filter the_content won't work)
I would like to insert a wp_query after the post content. After looking in different website, they all suggest using a filter on the_content. Example: add_filter( 'the_content', 'filter_the_content_in_the_main_loop' );
function add_query_after_content( $content ) {
echo $content;
echo *** The query ****;
}
add_filter( 'the_content', 'add_query_after_content' )
However it creates an infinite loop (the content in the query is filtered as well).
What is a good way to entering the query automatically after the post, **using a plugin that will work on most themes** ? | You should remove your hook before query.
function wpse_288691_add_query_after_content( $content ) {
$ouptut = '';

// Do your *** WP_Query *** and assign result to $ouptut.
// Reset query by executing `wp_reset_query`.
add_filter( 'the_content', 'wpse_288691_add_query_after_content' );
return $content . $ouptut;
}
add_filter( 'the_content', 'wpse_288691_add_query_after_content' );

why is the delete option missing from just one category?
A site I'm working on had one big category called `News`. I wanted to be a little more specific and create `Industry News` and `Company News`. Not a big deal at all, but when I go to delete `News`, I saw that delete options are missing! Both the checkbox...
![in the markup, there is a non-breaking space entity instead of a checkbox!](
...and the link that appears when you hover are just not there.
![where is that link?!](

extract serialized array to use for wp-query

I have built a page template that will display a loop of posts from a certain category, however I want the user to be able to select the categories they want to display in that loop, preferably when they create the page and select the template.

How do you get specific tags from the_content?
How would I grab specific tags from the_content? For example, I'd like to pull a list of all h1 tags. | Using `preg_match_all()` you can create a regex pattern to find and extract tags (and their content).
With Wordpress's `post_content` hook, you can find and list all the H1's within current posts content with something like:
add_action('the_content', function ($content){
// look for <h1> tags and text therein, anticipate class/id name
$findH1s = preg_match_all('/<h1 ?.*>(.*)<\/h1>/i', $content, $h1s);
// if found, show above content
if (is_array($h1s) && isset($h1s[0]))
return "<pre>H1's in this post: ".print_r( $h1s[0] ,true)."</pre>".$content;
// if none found, just return content as-is

Hide post title when single post with specific category
May I know is there a way I can show my blog post title under the below condition?
<header class="single-header">
<?php if(is_singular('post') && (!is_category('campaign-post'))) : ?>
<h2 class="page-title"><?php the_title();?></h2>
<?php endif; ?>
</header>
I have a few different categories, which I have created within Posts. One of it (campaign-post), I wish not to show the post title. So I have written the above condition. Unfortunately, no luck. The title still showing.
Can anyone show some clue how I can solve this problem? | Instead of
!is_category('campaign-post')
I think it's
!in_category('campaign-post')
* * *
`is_category()` is used within Archives pages, when it's in WP Query. Like your viewing a category archive page, and you're asking: _is this the category queried_.
`in_category()` (which uses `has_category()` which then uses `has_term()` which then uses `is_object_in_term()`) relates to single posts, asking: _does this post have this term_. | stackexchange-wordpress | {

Nested Page Template not showing in page attributes
I have a custom page template that I am trying to use on my WP site (version 4.9). The folder structure where I am placing my page templates are as follows.
theme-root (/wp-content/themes/mytheme/)
|-landing
|-template-name
|-index.php etc...
When all of the template files are placed up one level in theme-root/landing I can see the template in the page attributes box on the admin screen when editing the page. When it is placed inside the template-name folder it doesn't show up. I have a plugin to clear the file cache so the problem isn't from the caching of files. It is structured this way because the site uses multiple page templates. | In WP 3.4 they allowed adding template files one level deep.
Since then code has changed, however in `wp-includes/class-wp-theme.php`, in `offsetGet()` (from `__get()`) you'll see:
case 'Template Files' :
$files = $this->get_files( 'php', 1 );
Although I can't fully unravel the maze of code for loading a theme, the above suggests the second argument, `$depth`, is still set to only `1` deep for `Template Files`. Which would coincide with the troubles your experiencing.
You may want to re-think your themes folder structure, and/or your logic for selecting a template.
If you're conditionally checking which template was chosen based on a user selection in the first place, on your conditions using the `load_template()` andor `template_redirect()` might help out more than leaving it to Wordpress defaults. | stackexchange-wordpress | {

Apply Additional Discount after coupon
I want to provide special discount on cart items but want to apply right after the coupon OR when proceed to checkout is clicked.
**Example:**
The customer added an item in cart with total price $100 and he applied the coupon e.g `10%OFF`. Now the total remaining cost is $90 and now I want to apply additional 30% discount which will be on remaining cost ($90).
I found this but it does partial job:
function custom_wc_add_fee() {
WC()->cart->add_fee( 'Fee', -10 );
}
add_action( 'woocommerce_cart_calculate_fees','custom_wc_add_fee' );
First, it applies when the cart page is loaded. (whenever I need after coupon). Secondly, I'm unable to get the cart price so unable to apply percent discount. What I like about hook is that it adds a little description so customer knows what happened. | Put this code in your current theme function.php file. Set how many discount as per your require.

How to add gallery support in WordPress?

Thank you for you suggestions on how manage both adding support in back end and echo it in the front end. | You can use gallery-metabox. Its open source and easy to use;
<
From Readme ;
Include the `gallery.php` in your `functions.php`:

`$types = array('post', 'page', 'custom-post-type');`
In your template inside a loop, grab the IDs of all the images with the following:
`$images = get_post_meta($post->ID, 'vdw_gallery_id', true);`
Then you can loop through the IDs and call `wp_get_attachment_link` or `wp_get_attachment_image` to display the images with or without a link respectively:
`foreach ($images as $image) { echo wp_get_attachment_link($image, 'large'); // echo wp_get_attachment_image($image, 'large'); } ` | stackexchange-wordpress | {

how to access query string in wordpress?

Sharing post in Facebook shows UTF8 invalid character �

The thing is the famous question mark diamond shows up on some of the posts description.
All the OG Meta looks good (using Yoast SEO), it's 'just' the text on the share post itself that has this sign.

The `content-type` is also properly set to `utf-8`

The website shows up just fine with no weird characters, it's only when trying to share a post on Facebook.
How can I find the source for the wrong encoding ? | I've found the issue.
UTF8 might produce a multibyte string (when using Hebrew characters for example).
Facebook truncates this string a post is shared to keep the description under max number of characters.
However, they might truncate a multibyte character in the middle which will result in UTF8 invalid character:
This issue actually reproduces in all multibyte websites.

wp-config.php modified?

Configuring WordPress Auth Cookie Expiration
I'm trying to configure the WordPress cookie expiration time, but for some reason it's not working. I went here:
<
And put the following hook based on the doc:
function init() {
// ...
$expiration = 60;
apply_filters( 'auth_cookie_expiration', $expiration );
}
This code is called from a hook in my plugin's constructor:
add_action( 'init', array( $this, 'init' ) );
And I have verified that it runs.
I expected this to produce a cookie that expires in 60 seconds, but it doesn't. Instead it sets a regular expiration time of 48 hours (WP default). I suspect this might be because when the user actually logs in, it doesn't create this expiration date, and running this function later has no effect. I haven't yet figured out how to make it work though. Any help appreciated. | Note that you're not adding any filter callback with:
apply_filters( 'auth_cookie_expiration', $expiration );
Instead use:
add_filter( 'auth_cookie_expiration', $callback, 10, 3 );
where `$callback` is the appropriate filter callback that modifies the expiration.
Here's an example
add_filter( 'auth_cookie_expiration', function( $length, $user_id, $remember ) {
return $length; // adjust this to your needs.
}, 10, 3 );
or to fit with your current class setup:
add_filter( 'auth_cookie_expiration', [ $this, 'set_auth_cookie_expiration' ], 10, 3 );
where `set_auth_cookie_expiration()` is the appropriate method, e.g.:
public function set_auth_cookie_expiration ( $length, $user_id, $remember )
{
return $length; // adjust this to your needs.

wp-json and what data does it give away?
I just discovered `/wp-json` and it seem to give away some unwanted information. The entire json file is too big to scan everything so I decided to ask a question.
One particular thing I am concerned about is, it gives away user slug. Which kind of seem unnecessary to publish user id of site author. Should I be concerned or it is pretty common thing?
What other information does it give away? Should I be concerned and take any precautions?
Thanks. | `/wp-json/` is the base part of the Wordpress REST API
<
An authors ID isn't a big deal. I would imagine on your theme, every time the post authors name shows, within the HTML showing the name, there'd be element classes containing the authors ID. It's normal to have shown in publicly viewable source code, and it's easy to discover "hack" an id by simply making a query on your site `/?author=x` and manually mapping IDs to usernames.
The link above details the REST API, and what it does and can show. I'm over simplifying it, but: the REST API acts as basically your entire Wordpress site, in JSON format - with availability to query and do specific things.
If nervous about the API and not using it, it's easy to remove. | stackexchange-wordpress | {

Modular theme settings
I'm looking for advice on the best way to store a series of settings for a modular theme.
To note:
* The settings will not be user facing (not suitable for the customiser api).
* Ideally the options would not be stored in the database as they will be static (for performance).
* The theme is not public, it will be used as a framework for multiple sites.
I have discarded `add_option` / `get_option` which uses the database, and likewise for `get_theme_mod` / `set_theme_mod`.
Am currently using a global scoped array - which is not ideal (from what I read).
Any other thoughts / suggestions? | If a user can not change them then they are not options, they are constants. Declare them using `const` in your maim theme file (probably `functions.php` but any other files that is being always loaded will do), and use them wherever you have use the "options" array now.
If you want to control it without editing you theme files, you can use a conditional `define` instead (check if value is not defined yet and if not define it). That way you will be able to override the default values by defining them at the `wp-config.php` file per site.
... But this all question sounds wrong. The DB is there, so just use it, and a basic UI to control the options is easy to come up with. There is no real reason to resort to code changes every time you want to active/deactivate a module. | stackexchange-wordpress | {

Can a kind person please let me know what I'm missing? | The `get_the_post_thumbnail()` internally uses the `global $post` to get the post ID. That is why the code works while you are getting errors. it's not required to pass the post ID to this function, so you can pass `null` to it.
But the error is because there is no defined `$post_ID` variable. If you want to get the post's ID, you should either use `global $post; $post->ID;`, or better use `get_the_ID()`. | stackexchange-wordpress | {

Preventing BFA in WordPress without using a plugin

What is the most minimal way, without a "complex" plugin like WordFence, to prevent BFAs in WordPress admin?
The end state should be that IPs trying to enter more than x times get blocked for at least x time (presumably, the default values).
**Edit: Maybe SSHguard could help with that too?** | One **_plugin-free_** layer of protection you could implement is to route your traffic through a site like CloudFlare that has built in brute force protection.

Is "the loop" a template tag?

Is "the loop", the loopish function that shows posts while we have posts, based on if we have posts, should actually be considered a a template tag? | The `Template tag` is just a name chosen for a variety of function. It doesn't really matter what you call them, and they are functions.
However, the `while( )` loop itself is a simple PHP feature. It uses the `have_posts` method of the `WP_Query()` class to detect whether there is any posts to display or not. The main query itself is already set when you load a page, which can be accessed via `global $wp_query;`.
So, putting all together, this can be an opinion based question. The `WP_Query()` class doesn't exists in the File section of Template Tags page, so I would call it a _"No"_. | stackexchange-wordpress | {
