Easiest way to call an External rest API?
I am currently attempting to make a simple GET call on an external API and then to populate the page with the response, no matter I search I cannot seem to find a clear or understandable answer as how to do this or if it is even possible.
Edit:
I have found an answer, however I feel that I should expand on what I wanted as I feel that Mark Kaplun was right. What I wanted to be able to do was make an external API call to GET a response from my own backend service (dreamfactory in this case). The issue that arose, largely due to my unfamiliarity with WordPress, was that I could not find a way to send off an api call. What it transpired the issue was that I attempted to make the api call inside the page and not inside the "Functions.php" page that I should of done, calling a short-code inside the page editor to activate it. | Mark is right, without knowing more, this is a hard question to answer. This is a general guide though (not written by me) that I've used for my projects in the past.

Which has more impact on site performance? Template overrides or hooks
I'm building a website with the "Neighborhood" Theme and WooCommerce. The site is quite large and is heavily customized and I have to set dozens of divs to not display or edit the text, which I'm using a large translation function for that uses multiple switch statements. As well as hooks for editing multiple woocommerce buttons. So my question is, is it better in regards to performance to hide all of these divs and use the function to edit text and redirections, or should I override multiple template files in woocommerce to make these changes? | The templates are, by definition, the mechanism to define how a certain woocommerce page would look, and child themes are, by definition, the way you change a behavior of a theme beyond what it allows for in the Admin UI.
Overriding the templates in a child theme is the best practice. _(Bear in mind that this means you may have to come back and update the template when Woocommerce updates their templates.)_
Also, changing the content in PHP is usually cheaper than letting the default PHP run then changing the content in the browser, because it duplicates work. | stackexchange-wordpress | {

Custom page template with entirely different design. Is it possible in?
I'm trying to create 2 different page templates for a website here.
The idea is that admin should be able to select this new template for specific pages at the time of creating it. Also, they should be able to select the old design when ever they want.
What could be the best way to design a new page template with entirely new designs instead of changing any current designs? | Short answer is, yes it's possible.
That is the very purpose of having a template hierarchy. Different templates having different functionality and design based on your needs.
For example, you can create a `tag-facebook.php` and make it look like Facebook, while having a `tag-twitter.php` that looks nothing like Facebook, but just like Twitter!
There is one thing you should consider. Most of the page templates have the following structure:
// Header
<?php get_header();?>
// The page's content is here
// Footer
<?php get_footer();?>
If you follow this structure, you can't fully customize your page since `get_header()` and `get_footer()` will always include the same header and footer templates in your page.
Unless, you define different headers and footers to use in different designs. | stackexchange-wordpress | {

add_theme_support( 'post-thumbnails' );
then add
add_image_size( 'thumbnail-news', '100', '75', true );

Change the CSS of the Customizer API

Can I modify a WP_Query instance or clone it with modifications?
Let's say I have created a `all_movies` function that returns a `WP_Query` instance that includes all posts of a custom type `movie`.
$movies = all_movies(); // returns WP_Query instance
I would like to modify the `WP_Query` object to only show a certain author's movies, maybe in code like this:
$movies = all_movies();
$movies->filter(['author' => 14]); // not real code
Or maybe I could create a new `WP_Query` instance that copies the existing instance with modifications:
$movies = all_movies();
$new_movies = $movies->filter(['author' => 14]); // not real code
Of course, I would expect the query to be lazy only resolve at the last minute. I'm used to other ORM systems where something like this is possible. Is it possible with Wordpress' `WP_Query` class? | `WP_Query` can repeatedly _loop_ through the retrieved posts multiple times, but it was never meant to query them repeatedly/iteratively. You can just do `$query->query($args)` again, but there is little point as opposed to just making a new clean object.
In your case I think it would make sens to have your custom function accept optional parameters, along the lines of:

$defaults_args = ['stuff'];

}
So I just want to know this laziness is a right way or not:) | Yes you can. But to make sure the script has not already been registered or enqueued, use `wp_script_is()` as follows:
foreach( $jquery_ui as $ui ) {
if( !wp_script_is( $ui ) ) {

Get more than 10 posts in a specific category with the wordpress api

How to get the user meta data for a post?
Im trying to get the user meta data from a post but only getting the one user:

// Is there a function that I need to pass the post ID ($post["ID"])?
var_dump($user_id);
}
When another user makes a post, I cant get their meta data. How, please? | You can pass the post's author as an argument to `get_the_author_meta`:
get_the_author_meta('ID', $post->post_author);
The second argument is the user's ID. This is stored in the post object in your loop, which you can access it by using `$post->post_author`.
## Reason
The reason behind the current code of yours that isn't working is this piece of code that is included in the `get_the_author_meta()`:
if ( ! $user_id ) {
global $authordata;
$user_id = isset( $authordata->ID ) ? $authordata->ID : 0;
} else {
$authordata = get_userdata( $user_id );
}
If you set the second argument to true ( which is the `$user_id` ), it will trigger the `else`, and by triggering the else you are passing a `true` to the `get_userdata()`, which will obviously won't work.

Is this really always bad? (variables in l10n functions)
I needed to translate strings on another language than the current $locale, so I need to change the locale and restore it later, and I really couldn't repeat all the code for the 30++ strings I had to translate.
So I ended up with this function:
function __2($string, $textdomain, $locale){
global $l10n;
if(isset($l10n[$textdomain])) $backup = $l10n[$textdomain];
load_textdomain($textdomain, get_template_directory() . '/languages/'. $locale . '.mo');
$translation = __($string,$textdomain);
if(isset($bkup)) $l10n[$textdomain] = $backup;
return $translation;
}
Now, as per this famous article, I really shouldn't have coded that function :
<
...But it simply works. So my question is: is it really ALWAYS wrong to pass variabled to l10n functions? An eventually why? And why shouldn't I use my function if it just works? | The answer is: sometimes. As long as you know what you are doing, there are no problems in terms of bugs. There can be situations where this is possible and safe, and other where it can be necessary or extremely useful.
To complete and share the code above, I add the following:
function _e2($string, $textdomain, $locale){
echo __2($string, $textdomain, $locale);
}
// example
_e2('hello','stratboy','it_IT');

Is database safe after merging a branch of a more recent version over an older one?
Use case:
2 git branches:
staging (wp4.7x -- or whatever) production (wp4.7x -- or whatever)
Then I do a wordpress update on staging. Then merge staging files on production.
At this point, I will have all the most updated files on production, but the database wasn't touched. Dangerous? Or maybe wordpress will detect old db and ask to update? | For DB upgrades wordpress compares the db version number it hs in the code to the one in the DB. It makes no difference how the new code got there as long as it is the correct one.

How to Take Logo Out of Navigation Menu?
So I added my logo to the navigation panel at the top of my site. The theme doesn't support having a logo there... I just added the `<img />` code into the header HTML.
The only way to get the image where I wanted it though was to add it to the "top-navigation" section where all the page headings are contained.
I installed a responsive menu plugin and set it so the top navigation disappears and turns into the three bar icon when the page gets to a certain width (for example on a mobile device).
The problem is that since my site logo code is within the top navigation section the logo also disappears.
So basically I'm looking to take the logo code out of the top navigation section so it will remain when the page shrinks.
I have no idea how to code css or how to integrate the HTML with the css so I don't know how to do this.
My site theme is Fashionistas.
Very appreciative of any help. | I was going to leave this as a comment since questions about CSS are off-topic here, but it wasn't going to fit.
There is a rule in your inline CSS at line 75, which hides the menu of the screens sized less than 750 pixel. This is it:
@media only screen and (max-width: 750px) {
#top-navigation {
display: none !important;
}
}
Which hides both your logo and the menu. To revert this, you can either add your image outside the `#top-navigation`, or hide only the menu, not the whole navigation.
For example, add a simple media query and add it to `Appearance > Customize > Custom CSS`:
@media only screen and (max-width: 750px) {
#top-navigation {
display: block!important
}
#top-navigation .sf-menu {

EDIT: I just wasn't calling it by get_header(), sorry! | Simply having a `header.php` in your theme's folder will not output your header to the browser. You have to call the header too.
To call the `header.php` file, you should use `get_header();` at the top of almost every template (Almost!) such as `page.php`, `single.php`, `archive.php` and so on.
Do the same for `footer.php` to get the footer.

Line numbering on Wordpress frontend

> Second line

> This is the third
I want my front-end page to look like this
> 01 My first line
>
> 02 Second line
>
> 03 This is the third
Can it be done with code or a plugin? | It's not really a WordPress related question, but it's kind of related to visual editor.
If your content is just raw text separated by `<br>` tags, I can't think of any way to do it. But if your content's structure is like this:
<p>My first line</p>
<p>Second line</p>
<p>This is the third</p>
Then you can use a CSS feature called counter:
body {
counter-reset: section;
}
p::before {
counter-increment: section;
content: "Line number " counter(section) ": ";
}
This will output the following result:
> Line number 1: My first line
>
> Line number 2: Second line
>
> Line number 3: This is the third
Which you can customize it to get your favorite style. It doesn't have to be `p` element, it can be anything. Actually `p` elements are already considered as blocks, and automatically occupy a new line. You can see more examples at W3 Schools. | stackexchange-wordpress | {

wp_mail ignores the name in From field
I am trying to set custom From name and email in `wp_mail` headers but somehow, `wp_mail` ignores the name but gets the email correctly.
This is the headers code I am using.
$headers = array(
'Content-Type: text/html; charset=UTF-8',
'From: Michelle Titus <[email protected]>'
);
I am not using such plugins which can alter the data. However, I am using GravityForms which I don't think should conflict with what I have here.
I cannot use the `wp_mail_from_name` and `wp_mail_from_email` because the `wp_mail` is called dynamically with different From data each time. Maybe I can put some conditional logic but I thought I should ask for a better solution.
And there's no question resembling my issue anywhere, as far as I searched Google.
Thanks | Is there an actual `[email protected]` email address? And (more importantly) is the `brazilbr.com` the domain name of your site? If not, then your hosting place will ignore the 'from' email when it processes the `wp_mail(`) command.
You need to make sure that the 'from' email address you use in `wp_mail()` is an email address on the domain for your site. If needed, created an email account on your domain, then use forwarding rules to get it to the [email protected] email address.
You can also set the 'reply-to' in the mail header to whatever you want. But the sender email must match the domain of the site that is sending the mail. If not, the mail will get delivered, but will not have the 'from' address you specified. And, some mail clients might block your email as spam, since the sender email doesn't match the sender domain. | stackexchange-wordpress | {

Pass variable from action back to template
I'm new to developing with WordPress. I read here that a good way to process data posted from forms is to insert an action on the init function like so:
add_action( 'init', 'contact_form_send_email' );
My function seems to be processing the data correctly, but I can't figure out how to make a variable available within the same template that has the form.
What is the way to do this? I've heard that setting global variables is not a good way to go. | The difference between `add_action()` and `add_filter()` is semantic not technical, except that a filter expects a returned value and an action does/will not. The question is whether `contact_form_send_email()` **needs** to be called-at /hooked-to `init`.
If not, you can define your filter in the template with `apply_filters()`, and then hook to it to run your function and return a value to it.

How to add a link to the tax term in the admin Edit page?
I have a custom taxonomy, 'genre.'
I'd like my editors, from the 'Edit Genre' screen (in the admin), to be able to link to the front end page for that genre/term.
So, at the top of the 'Edit Genre' page there would be a link such as:
See this page: mysite.com/genre/fiction
* or - if I could have a 'Preview Changes' button, as in the Post Edit screen.
Possible?
Note, I've seen some solutions that suggest putting in a dummy custom meta box, using the description as the text/link. Is there a way to do the above without doing the meta box? | The dynamic hook `{taxonomy}_term_edit_form_top` can be used to output a link to the term's archive page.

What's the best way to 'include' a file in WordPress?
Ive built simple web applications in the past using 'include' functions and typically I've used this command:
<?php include($_SERVER["DOCUMENT_ROOT"] . "/data.php"); ?>
This has worked great OUTSIDE of WordPress but my question is - can this be applied to a WordPress Environment?
_(I should add the reason I am doing this: it is because I have to load a file which is approx 2MB into a WordPress Template and it crashes each time I try to save the file)._ | You can include the PHP files in WordPress just the same way you do it anywhere else.
However, WordPress offers more constants and functions for defining a path for the `include()` function.
Instead of using `$_SERVER["DOCUMENT_ROOT"]`, move your PHP file to your theme's folder, and use this to include it:
require_once ( get_template_directory() . "/data.php");
The reason behind moving the file to theme's folder is both for security, and organization. Now, use this in the _very first line_ of your `data.php` file:
if ( ! defined( 'ABSPATH' ) ) die();
This will prevent direct access to your PHP script by entering the URL. `ABSPATH` is a core WordPress constant, and if it's not defined, then it means your script is probably being accessed directly.
Also, to prevent accidental conflicts occurred by including the file multiple times, I would suggest you use `require_once()` instead. | stackexchange-wordpress | {

Header Sidebar Won't Move Lower - Want to Align with Header Logo

attach unattached featured images to respective posts

Why does the_post_thumbnail output full sized images after activating post-thumbnails support?
I mean:
add_action( 'after_setup_theme', 'thumbs_setup' );
function thumbs_setup() {
add_theme_support( 'post-thumbnails' );
}
My media settings are 150x150px on thumbnails, but now `the_post_thumbnail()` will output a full sized image instead. Why?
I see that the only way to have `the_post_thumbnail()` to really output the thumbnail size is to explicitly pass it:
`the_post_thumbnail('thumbnail')`
Why? | I think adding support to 'post-thumbnails' also adds a new type of size: 'post-thumbnail'. But 'post-thumbnail' **is not** == 'thumb' or 'thumbnail', it's a new, different type. Also, `the_post_thumbnail()` if called without params will output the 'post-thumbnail' size instead of the 'thumb' size.
'thumb' (or 'thumbnail') are setted via admin media panel, while 'post-thumbnail' is not.
Since the 'post-thumbnail' size is not yet setted, than `the_post_thumbnail()` doesn't really know what size to use, and thus it will output the full image.
To set the 'post-thumbnail' size you must use standard `add-image-size()` passing 'post-thumbnail' as the name, or, just use `set_post_thumbnail_size()`. | stackexchange-wordpress | {

HTTP Security Headers in wp-config
Is there a way to place the HTTP Security Headers in `wp-config.php` instead of in `.htaccess` or `functions.php`? If so, what is the format? | The `.htaccess` file is read by the Apache server software before it even hands over to WordPress to generate a page. It is by far the best place to have your security headers.
That said, WordPress does have a class to modify the headers before they are send to the browser. This class contains a filter which you could use in a plugin. Beware that this filter might be bypassed if your page is served by a caching plugin (or some server level form of caching).
The `wp-config.php` file has a fairly narrow scope, as you can see in the codex. Defining security headers there is not among the possibilities.
Bottom line: yes, there are some ways to set security headers within WordPress, but make sure your `.htaccess` is in order. | stackexchange-wordpress | {

Creating a simple button inside of a widget

Normally, this would work fine, like in this JS Fiddle: <
However in my WordPress widget, `.et_pb_widget a` is overriding everything else. And if I tried to just apply CSS to `.et_pb_widget a`, it's going to add it to all my widget links, which I do not want.

do_action( 'save_post', $post_ID, $post, $update );
//Fires once a post has been saved.
do_action( 'wp_insert_post', $post_ID, $post, $update );
Am I missing something? Or doesn't `wp_insert_post()` trigger the `publish_post` action? | It's triggered in `wp_publish_post()` that calls:
wp_transition_post_status( 'publish', $old_status, $post );

I'm coding my own custom install.php (wp-content) and I want to be ablt to activate my custom theme when an install is running. Right now I've tried switch_theme('theme-slug') which works, however when I first log in to my admin panel, all the admin pages under Settings etc. is gone, so something is not right. If I remove switch_theme function from my install.php, then it tries to activate "twentyseventeen" however it can't find that theme, and that's because I've removed it from the themes folder, because I want to activate my own theme called "mastertheme".
Can somebody help me on how to activate my own theme when WordPress installs? | Twenty Seventeen is the default theme if no default theme has been defined. line 359 from _wp-includes/default-constants.php_
if ( !defined('WP_DEFAULT_THEME') )
define( 'WP_DEFAULT_THEME', 'twentyseventeen' );
You do not need to edit that file, however, to change this.
Simply define your theme in the file _wp-config.php_ just before this line:
`require_once(ABSPATH . 'wp-settings.php');`
Like so:
define( 'WP_DEFAULT_THEME', 'my-new-default-theme' );

Rewriting rules: difference between 'init', 'rewrite_rules_array', 'generate_rewrite_rules'?
I was wondering, what's the difference, and best filter/action to add rewrite rules? I used all but I still can't say why should I use one or the other.
add_action('init', 'add_rewrite_rules'); // or:
add_action('generate_rewrite_rules', 'add_rewrite_rules'); // or:
add_filter('rewrite_rules_array','add_rewrite_rules'); | Use whatever is simplest for your needs.
If you just need to add a rule to the stack, use `add_rewrite_rule` on `init`.
`generate_rewrite_rules` and `rewrite_rules_array` give you access to the whole rewrite rules array. Use these if you need to modify, remove, or reorder the rules. | stackexchange-wordpress | {

How to see if event is featured in PHP?
I'm using The Events Calendar by Tribe. What I'm looking for is a way to see if an event is featured without using the shortcode and rendering their markup. Is there a conditional available such as `tribe_is_featured_event()` or something along those lines? I have not been able to find anything online regarding this. As a last resort, I will make a call to the database although I'm not sure where this is stored. | I believe you would want to use this function (from `the-events-calendar/src/Tribe/Featured_Events.php:45`):

return false;
}
return (bool) get_post_meta( $event_id, self::FEATURED_EVENT_KEY, true );

How can i get the post's full html source by its ID?
Is there a way that i can get the HTML source of a single post dynamically from within WordPress site?
for example, if i wanted an external html I would use:
file_get_contents($url)
or using cUrl, But I'm looking for a way to do it from within my WordPress to get full qualified HTML for one of my posts
Is that possible ?
Thanks in advance | If you have the post's ID, I assume that you are the owner of the blog ( Not because others can't have the ID, but because only the owner should do such tasks ).
To convert the post ID to the post's URL, you can use `get_the_permalink()`:
$url = get_the_permalink( $id );
Afterward, you can use `file_get_contents()` to fetch its content, including the full source of that web page. So, your full code will be:
$url = get_the_permalink( $id );
$data = file_get_contents( $url );
Which data is your HTML source. Note that this will only work in the WordPress environment. | stackexchange-wordpress | {

Disable permalinks on all pages and posts
As I am using the JSON API, the permalinks don't make sense. My site URLs are totally different to the ones generated by the permalinks, so this is likely to confuse the client.
Is there any way I can disable permalinks on pages and on the default post type? I was able to do it on custom post types by specifying `'public' => false` but how do I make this change site-wide? Even the media pages have a permalink. | Since WP 4.4, there is a hook you can use to edit default arguments for registered post types:
`register_post_type_args` (view in context on trac)
If you're wanting to remove the permalink/slug from the edit post/page screens but not remove posts from the admin menu itself, setting `public => false` and `show_ui => true` should do that.
function remove_from_public( $args, $post_type ) {
$args['public'] = false;
$args['show_ui'] = true;
// some other common uses:
//$args['show_in_rest'] = false;
//$args['rewrite'] = false;
//$args['rest_base'] = false;
return $args;
}
add_filter( 'register_post_type_args', 'remove_from_public', PHP_INT_MAX, 2 );

create filter in functions.php
I want to create a filter in my functions.php theme to change the URL of $icon_html in this plugin function.
public function get_icon() {
// paypal icon
$icon_html = '<img src="paypal.png" />';
return apply_filters( 'woocommerce_gateway_icon', $icon_html, $this->get_id() );
}
How to perform this? $icon_html is not unique.
Thank you, Thibault | Whenever you see `apply_filters( 'filter_name', $value )`, you can use `add_filter()` to replace or modify the value of `$value`:
add_filter( 'filter_name', 'callback_function' );
Where `callback_function` is a function that you create. That function will accept `$value` as an argument, and needs to return a new value. So for your example, that will look like this:
function wpse_275788_replace_icon( $icon_html, $id ) {
$icon_html = 'Put new icon html here.';
return $icon_html;
}

Is there any way to do that? | So just to clarify, you've already setup the multisite by following: <
And the multisite is working and you can create subdomains. But you want your current site to be a subdomain?
If so, I think the best way to do this will be to create the new sub site first, then use a cloning/migration plugin to copy all your data from your current site to the new sub site. WordPress has it's own export-import plugin:
<
The WordPress Importer will import the following content from a WordPress export file:
* Posts, pages and other custom post types
* Comments
* Custom fields and post meta (this will include your post thumbnails and attachments).
* Categories, tags and terms from custom taxonomies

Then you can remove all the data on your root site.

Wordpress as a backend for external service?
I created php REST API for old windows application of our company.
Through the REST API I display data on a web page.
I want to manage our data through Wordpress, like classic custom post with custom fields
**My concept:**
1. Loading data over REST API into WP backend (I don't want save these data to WP database)
2. Show list custom post (like from Wordpress DB)
3. Edit and Save post to REST API, not to Wordpress DB
It's possible? If so, how? | Yes, you could create a plugin to produce admin pages that connect to the REST you've made for your application, and provide a gui to interact with its endpoints for CRUD operations. It would be, essentially, no different than connecting to any other external api (i.e. a Mailchimp or Google api).
If you are only looking to provide a gui for interacting with your windows application, there may be less constrictive options. (ng-admin comes to mind)
If, however, your application has other tie-ins to a wordpress install (data lookup relevant to some other content management operation for instance), then look into the Plugin Developer's Handbook.
You may need to create custom capabilities for user roles to manage access to your CRUD operation endpoints.

Let me know if you need more details. | This is happening due to encoding. I assume you have a function in your search page, which you get and use `search_text` inside that template. You should decode the URL before doing so.
The `urldecode()` function would be what you are looking for. Your string is also UTF-8 encoded, so this is what you are going to need:

How to Display Post Excerpts in Admin by Default?

Show with echo if a post has two or more categories
I am not exactly an expert in php and less in wordpress. I wanted to know if they are so kind that I have a fault. I explain, my problem is that I want to display a div with echo in a post if it has these two categories (or more). I am attaching the code. Thank you very much and greetings!

elseif (has_category(array('aloe vera', 'jeran'))) {
echo $bplant; }
elseif (has_category(array('rabbit', 'cow'))) {
echo $banimal; }
else
echo "No";
?> | To answer your question, if placed within the Loop - after, typically, `while ( have_posts() ) : the_post();` in a single.php file - the code will work as follows:
* The `has_category( array( 'x', 'y' ) )` condition will be satisfied if the post is in either x or y, or both, regardless of whether it is in any other categories (assuming an otherwise unmodified main query and no other conditions).
* In your example, if the post was in both "jeran" and "cow," then `$bplant` would be echoed, but not `$banimal.` I think you probably already understand why.
* If a post must have **both** of the two categories, then you'll have to work the logic out accordingly- e.g., `if ( has_category( 'x' ) && has_category( 'y' ) )`, etc.

$timestamp = strftime("%Y-%m-%d %h:%M:%S %a", time() - 3*60*60);
Now you have a formatted value of 3 hours before, which you can use in `date_diff()`. | stackexchange-wordpress | {

Create a WordPress template without navigation and footer
As the title suggests, I'd like a page template to have NO navigation and NO footer.
All my page templates have this:
<?php
/*
* Template Name: Blah Blah
*/
if (!defined('ABSPATH'))
exit; // Exit if accessed directly
get_header();
?>
But if I remove the above code then the entire page won't work. | Don't remove `get_header()`.
Duplicate the `header.php` to `header-{custom-name}.php`, let's say (`header-nonavfooter.php`) then in the template file replace `get_header()` with **`get_header('nonavfooter')`**.
In the new header file (`header-nonavfooter.php`) remove the code related to navigation.
Do the same for the `footer.php` also(Create a new footer.php and remove the footer parts that you don't need), remember not to remove `wp_footer()` available in `footer.php`. | stackexchange-wordpress | {

How to set a Background image in Wordpress?
I want to set a background image (jpeg) for my home page only and not for the whole site. Right now it is white color for the whole site. This is the code in function.php:
// Background color
$background_args = array(
'default-color' => 'ffffff',
);
add_theme_support( 'custom-background', $background_args ); | The way I see, you have 3 options:
* You can achieve that with CSS. Just target the div you want to put the background in. Target it in a way that only shows at the home of the site (check the ID and class of the body div, it usually has names like 'home-template' and such.
* You can achieve that with HTML. You can 'hard-code' the style inline, in your PHP file, like you would do in a HTML one. You can do that, if the body of the document is in a file that _is not header.php_.
* (recommended) You can achieve that with PHP using 'is_front_page' (< Just do a conditional that checks if the page is the front page. If it is, you can attach and ID to the body, or style it inline. Else, just use the regular body. | stackexchange-wordpress | {

Hide disclaimer from summary excerpts
I have a system that works well for me where I can add a tag of affiliate to a post and then this code in my functions.php file adds a disclaimer to the beginning of the post:
`/* Add disclaimer to top of POSTS that contain affiliate tag */ function tt_filter_the_content( $content ) { if (has_tag('affiliate')) $custom_content = '<hr><p><em>Disclosure: This post contains affiliate links and we may receive a referral fee (at no extra cost to you) if you sign up or purchase products or services mentioned.</em></p><hr>'; $custom_content .= $content; return $custom_content; } add_filter( 'the_content', 'tt_filter_the_content' );`
I've been using this method for a while and it works great. However, I noticed that on my summary excerpts and my feed, it shows that disclaimer as well. That makes it a little messy and cuts away from a lot of the summary text showing up.
Is there a way to filter this out from being applied to the summary and my RSS feed? | You could do something like this:
/* Add disclaimer to top of POSTS that contain affiliate tag */
function tt_filter_the_content( $content ) {

$custom_content .= $content;
return $custom_content;
}
add_filter( 'the_content', 'tt_filter_the_content' );
Now you are checking if the tag exists and if it's a single post. If this still shows up in the feed, then you can change the if statement to something like:
