append PHP function to the_content
I'm using the Jetpack plugin for related items and social sharing. Both of these options filter the_content and append themselves to the end of it. The problem is that I'm using custom navigation in my posts which I output by using this code above and after `the_content` in my `single.php`.
<div class="navigare">
<?php multipagebar(); ?>
<div class="dropdown">
<?php TA_content_jump(1); ?>
</div>
</div>
I know that to append something to the_content I can use a filter:
add_filter('the_content', function($content)
{
return 'text-to-append' . $content;
});
My question and problem is: how to append the navigation PHP functions so that they display before the related and social sharing items of Jetpack? | You will need to experiment with priority.
add_filter(
'the_content',
function($content) {
return 'text-to-append' . $content;
},
10 // this is a priority number; 10 is default
);
The "10" is the default priority. I don't know what number JetPack uses but your original code, without a priority, should run at "10" so I'd try "9", or "8". It should be possible to get your code to execute before JetPack's code. | stackexchange-wordpress | {

Wordpress tags as twitter sharer URL hastags
I want to share a wordpress post on twitter. I'm using this :
<a href=" the_permalink() ?>&text=<?php the_title() ?>&via=<?php the_author() ?>&hashtags=<?php the_tags('', '') ?>" ></a>
My problem is that `the_tags()` prints the tags inside the `<a>` tag. How can I use `the_tags('', '')` ( which separates the tags with comma as the hashtag needs to be ) for twitter hashtags ?
I would appreciate any solutions without the use of a plugin | `get_the_tags()` with a little bit of processing will do it:
$tags = get_the_tags();
$tag_list = wp_list_pluck($tags,'name');
$tag_list = implode(',',$tag_list);

Change header based on visitor choice
I need to show a different header file ("header-tourist.php" and "header-agent-php") based on a choice the visitor will make. For example, I have 2 main buttons: `View site as Tourist` or `View site as Agent`. Based on this, I would like to show a different header throughout the whole site.
What is the best way to approach this (global variables, sessions etc.) ? | I would approach this by setting sessions.

How to remove the statusbar from the default wordpress editor?
How to remove the letter P from the default wordpress editor? Previously i have removed that P but now the entire code changed from the `class-wp-editor.php` file.
> !WordPress 3.9.1 WP_Editor | This ended up working for me, uses the tinyMCE init filter to remove the 'statusbar' entirely.
/** Edit TinyMCE **/
function myformatTinyMCE($in) {
$in['statusbar'] = false;
return $in;
}
add_filter('tiny_mce_before_init', 'myformatTinyMCE' );
Even with CSS, I couldn't find a way to definitely remove the path but keep the status bar - here's the CSS option:
function my_theme_add_editor_styles(){
?>
<style type="text/css">
.mce-path {display: none!important;}
</style>
<?php
}
add_action( 'admin_head', 'my_theme_add_editor_styles' );
**EDIT**
Changed the hook from `init` to `admin_head` as `init` would cause widgets to auto close when you would drag them to the sidebar - strange occurrence. | stackexchange-wordpress | {

Let Posts be stored in another table
I am trying to develop a plugin that creates a new table in the Wordpress database and I want to store there some kind of posts I create.
I am trying to understand how to "clone" the Wordpress Posts/Add New/Categories/Tags and store the posts not in wp_posts, but in another table (eg.: wp_special_posts).
At the moment I have the function that creates the table at the plugin activation, I created the page that grabs the information from the DB and display them using _WP_List_Table_ , but I do not have an idea on how, and if it is possible, to clone those sections.
And help? Hint?
**UPDATE**
I want to create a product section with its own table, called _wp_product_instore_ , and I also want to use the standard _post-new.php_ interface, but put the posts in the _wp_product_instore_ table instead of _wp_posts_. | Use `save_post` action hook as shown below but write custom insert/update queries to save information in a different table.

$title = $_POST['post_title']; //example variable
$wpdb->query(
$wpdb->prepare(
" INSERT into wp_product_instore ( post_id, meta_key, meta_value ) values ( $post_id, 'post_title', $title )" ));

Blocking Plugin Css to load custom in template directory
What is the most popular method to stop/block a plugin from loading their css styles ( located in the plugin directory) so that I can use the custom copy I made (located in my template directory).
I ask this because I have one css document ( complied using sass,scss and grunt) that a visitor of my website loads. I want to add the plugin css to that document ( and to use the sass variable functions).
Many thanks. | You can dequeue a style, for do that you can use wp_dequeue_style() or wp_deregister_style()
To use both of them, first u need to find the **handler** of the style you want.
Go to the plugin's folder you wanna remove the css and search for wp_enqueue_style or the file name and locate the handler.

add_action( 'wp_enqueue_scripts', 'my_fontawesome_deregister_styles', 100 );
function my_fontawesome_deregister_styles() {

Should I store my Facebook access tokens?
I've built a custom login page for a Wordpress site which uses Facebook for authentication.
Is there any reason to store the Facebook access token in my WP database, or does it make more sense to use a PHP session? Are there any benefits to storing these values on my server? | There are a number of explanations here: <
The time it takes for your server to talk with facebook does contribute to a good amount of slowdown. So it depends on how intensely you plan to use the api. In that case, storing the key and other fb related user data can cut that cross-talk considerably.
If you are just using facebook as a login authenticator I don't think you need to bother.

How to count the length of a post title?
Let's say that I have an entry titled **Crime & Punishment**
I tried to count the number of characters of my entry titles using the following line:
echo strlen( get_the_title() );
I expected the code would give me 18 characters for **Crime & Punishment**, but the result turned out to be 23 characters.
The code above didn't give me my desired result since it reads the symbols within the title as a _HTML code_. Is there any workaround for such case? | There are actually two problems:
1. The `&` is encoded as `&`, so you have to use `html_entity_decode()` first.
2. Multi-byte characters need more than one byte, and `strlen()` will fail with them. Don’t use strlen().
So use something like this:
$title = html_entity_decode( get_the_title(), ENT_XML1, 'UTF-8' );
$length = mb_strlen( $title, 'utf-8' ); | stackexchange-wordpress | {

Function Error after WP Upgrade to 3.9.1

Can I protect a type of content site-wide with a single password?
I am developing a theme for a client who has a catalog of products. Each product has a spec sheet that he wants to make available to logged-in users. It's not a real security issue, just a means to simplify the page for casual visitors. Right now he emails clients a password and keeps track of logins based on which password he gave out. He'd like to continue doing that.
So I'd like to come up with a way of:
* logging a user in with a single field
* using `is_user_logged_in()` and related inquiries to check whether to display links to the protected content
* denying such visitors access to the Admin side completely
Is this out of the scope of WP user roles? If not, any suggestions on how I could achieve this? | I would approach the situation like:
1. Create an user with subscriber role.
2. Add a meta field to the user profile. This will be the password like field you will verify the user against.
3. Use AJAX to verify the password(meta value) entered by the visitor and display product specification accordingly.

Wordpress loop for multiple custom post types

echo '<ul>';
echo '<li>'.get_the_title().'</li>';
echo '</ul>';

Password protect media attachment - share across guests

<?php if($currentuserid == foobar): ?>
<a href="PROTECTED/CONTENT.pdf">LINK</a>
<?php endif; ?>
If I were to create a user with ID `foobar`, and then give its password to several people, would it cause any problems if they all decided to use it at once?
I would only want to use their logged-in status to show/hide certain content - they would not be accessing the admin side. | When logging into WordPress with a user account, WordPress checks your credentials against those stored in the database. If they are correct, it then sets a session variable in your browser and you are able to view all areas that check against this session variable to gain access to.
Sessions are set on a per browser basis so it does not matter how many browsers are accessing the site as they will each have this session created on their own browser if their credentials successfully authenticate.
You would only run into problems if for example multiple users were trying to write to the database at the same time for example but in your case there is no admin access so for viewing purposes only, not problem.

How To Style Links in Content Area With <span> Tag Automatically?

Get template part vs locate template function
I'm in single.php where I'm trying to get related-posts.php template. The problem is that when using get template part the related-posts.php isn't getting custom taxonomy name from single.php in `wp_Query`.
The solution is getting the wp post terms once again in related-posts.php in order to use `get_template_part`. But technically it shouldn't be required since parent (single.php) is already having it.
But when I use locate template function it works fine. I feel that this method would be slower than `get_template_part`. What should I do? | First of all note that `get_template_part` internally uses `locate_template`, so your feeling that the latter is slower is wrong.
If you look at the code, `get_template_part` is little more than a wrapper for `locate_template`, so if one work and the other not, there are 2 possibilities:
* you are using `get_template_part` wrong
* there's some hook on `"get_template_part_{$slug}"` action that prevent it works
However, if `locate_template` works, use it: it's not slower, to be honest it can be pretty faster if there are functions hooked on `"get_template_part_{$slug}"` that slow down execution. | stackexchange-wordpress | {

Trying to hide subcategories which have categories without posts
On custom archive pages, I want to show subcategories that **_don't_** have their own posts but have sub-subcategories that **_do_** have posts.
And if a child category does not have posts, I want to hide its parent too.

if(is_category() && $has_category_children){ //$has_category_children is true if the current category has subcategories.
$args = array(
'hide_empty' => 1,
'hierarchical' => 0,
'parent' => $term->term_id,
);

foreach ($categories as $cat) {
echo $cat->category_nicename;
}
}

How would I go about adding custom header images per category?
I am using WooCommerce along with the Neighborhood theme. I am trying to figure it out but I need some guidance if anyone can offer it. | You can do it by adding some code or by installing a plugin.
You can add the following code inside your loop:
if (in_category('news')) {
get_header('news');
} else {
get_header();
}
This code checks if the current post belongs to a category that's called news, and if that's true, then it will use header-news.php instead of header.php.
You will have to create header-news.php inside your theme and add your custom header image in it.
Or you can install the following plugin which allows you to add a custom header to pages, posts, categories, or tags:

get meta fields and taxonomy of any post type

I know that this information is not saved in DB unless a post is created, so is it possible to read this information like WordPress is reading or please suggest me if this is possible or not. | If I understand correctly you want to get the taxonomies associated with a custom post type object, not with a specific single post. To do that you can use get_object_taxonomies(). For example, to get the names of the associated taxonomies to "my-custom-post-type":
$taxonomies = get_object_taxonomies( 'my-custom-post-type', 'names' );
foreach( $taxonomies as $taxname ) {
echo $taxname;
}
I think you can not do the same for meta fields because meta fields are associated with a specific single post not with a post type object. You will have to hardcode the relationship between metafields and custom post type. | stackexchange-wordpress | {

get categories the post was in and just been removed from

//Handle this category

'pre_post_update',
function($post_ID,$data) {
var_dump($post_ID,$data);

Are term IDs unique even between multiple custom taxonomies
I can't find the answer for this question on either Wordpress or here, nor via Google searches, so I'm throwing this out to the community.
If you have two taxonomies, and you add 1 term to each taxonomy, will the first term added in taxonomy_1 have a term ID of 1 and the second term added to taxonomy_2 have a term ID of 2? | The short answer is no. If you have a look at terms, taxonomies and categories, all of them is stores in the database in the `wp_terms` table.
Every one of these are assigned a numerical value that is unique to that term/category/taxonomy. This don't just apply to "objects" added to `wp_terms`, but to anything added to a specific table in the db. So nothing added to a specific table will ever have the same ID
These ID's are assigned according to the "object's" place in the specific table, in numerical order. So if the last item in that specific table is number 16, the next item that is added will be number 17, hence ID 17 will be assigned to that "object". The next "object" added will then automatically be ID 18 and so forth
So, to conclude, ID's are assigned to their place in a table, and not according to their relation to another "object" | stackexchange-wordpress | {

!enter image description here
Here's the screenshot in DropBox. | My current understanding is that the problem was caused by the fact that my project only encompassed a plugin directory while the page I was debugging was generated by many php files outside the project directory.
The fix took just two changes to PHPStorm preferences:
1. Go to `PHPStorm > Preferences > Project Settings > PHP > Debug` and disable `Force break at the first line when no path mapping specified`.
2. Go to `PHPStorm > Preferences > Project Settings > PHP > Servers` and disable `Use path mappings (select if the server is remote or symlinks are used`.
With those two changes, it all seems to be working perfectly fine. | stackexchange-wordpress | {

Active DB queries in Wordpress?
I just make some researches regarding to wordpress DB queries and I just wonder if I miss something
a normal `SELECT` query for example in Codeigniter with active records would look like if I assume I init my DB instance in both of the cases inside of a Class as `$this->db`
$data = $this->db->get('wp_mytable');
$data->result();
**Wordpress way**
$data = $this->db->get_results('SELECT * FROM wp_mytable');
and if I would use a condition than would look like
$this->db->select('*');
$this->db->from('wp_mytable');
$this->db->where('id', 1);
$this->db->result();
I find this handy if I would use more than one `WHERE` as array
but I do not see this kind of query types in wordpress wiki or I do not search in the right place? | `wpdb` doesn't include such kind of API, mostly since it descended from ezSQL which didn't either (as far as I remember).
While there are _some_ helpers for insert/update stuff, most of query abstraction happens in `WP_Query` since that's where bulk of complicated querying is typically going on. | stackexchange-wordpress | {

Remove from "Wordpress" when reciving email (Should I remove filter?)
I am getting "Wordpress" when I sending my email using wp_mail. So to remove "Wordpress" from my e-mail I am using filter like so:

function remove_from_wordpress($email){
$wpfrom = get_option('blogname');
return $wpfrom;
}
add_filter('wp_mail_from_name', 'remove_from_wordpress');

My question: Is this a proper way to do it? Because I am concerned that my filter will maybe break some other plugins. If that is the case how can I avoid that?

You are deregistering your sidebar correctly. For some reason you are registering it, or something. I don't see the need or use for this.
The other possibility that I'm thinking of for using this code is that somewhere you are registering your own custom sidebars.
If that is the case, you are most probably reusing the ID of the sidebar you have deregistered. Try changing the ID to 12 of your new sidebar. You can not reuse ID's. All ID's needs to be unique | stackexchange-wordpress | {

Which hook if user profile information is updated?

How to tell which Plugin is displaying?
I'm editing a Wordpress website for a client that was written by someone else. I'm noticing that a video and button are displayed on the home page. I used the Reveal-Template plugin to figure out which template was displaying but I can't seem to figure out which plugin is being used to display the video and button. I'm sure it's a plugin too because I changed the video yesterday.
The problem I'm trying to fix is that I want to put a link on the button but currently, it only gets set by a drop down menu. This means I'll need to go and edit the plugin being used to allow for a URL instead of just internal pages.
If I could figure out which plugin it is, I would go edit that code. Does anyone have a good way of figuring this out? I'm very new to Wordpress development so I apologize if this is a really basic question. Thanks in advance for your help! | It can be less than trivial to match output to a source code responsible in WordPress.
The typical cases are following:
1. The output is produced by template file directly. The locating template responsible is often about just searching for full or partial text match. From the other side template files can be identified among all files being loaded.
2. Output is produced by function call in template file. This is not far from previous case, but can be slightly trickier since code definitions is now in separate place from code execution.
3. Output is produced by function call, hooked to an action/filter. This can be nightmarish to unwrap, especially in cases of things getting nested.
In a nutshell good search tool is always a solid start. After that it's matter of what you typically work with and what tools are fitting for that. Personally I find `Query Monitor` plugin striking good balance in providing debug information but not _too much_ information. | stackexchange-wordpress | {

Is it possible to make one of two custom fields in Custom Post Type UI Required but not the other?
I'm new to wordpress and I'm trying to make a field that either links to a page internally via a dropdown OR a text area for a URL. Obviously I don't want the button to have two destinations so I'd like to make them both required but only one can have a value at a given time. Is this possible in CPT UI? | You should use Advanced Custom Fields. If I understand what you want to do correctly, you can add a Select Field with Radio Buttons, and then build conditional Page Link and Text (for the URL) Fields that appear based on the Select Field button.
You would then build an if/else statement in the code:
<?php if(get_field('page_link') == "internal"): ?>
<a href="<?php the_field('internal_page_link'); ?>">Page Link</a>
<?php else: ?>
<a href="<?php get_field('external_page_link'); ?>">Page Link</a>
<?php endif; ?>
You can set the two options up to be conditional based on the selected button from select field.
Also note in this example, you should use `get_field` for the Text field. This will return it as a string and not output text to html. | stackexchange-wordpress | {

How can I determine what mode the editor is in and when it changes?
I need to determine if the page/post editor is in Visual or Text mode. I also need to determine when this changes.
Does WordPress provide some kind of functionality for doing this? I am writing some JS that requires this information. | 1. To determine what mode the editor is currently in, you can use the `getUserSetting('editor')` in JavaScript, which returns either "html" or "tinymce".
2. To determine when the editor mode is switched, you can use the jQuery `click` event handler on the `#content-tmce` and `#content-html` elements, which are the editor type switching buttons:
jQuery( '#content-tmce' ).click( function() { // Visual editor selected } );
jQuery( '#content-html' ).click( function() { // Text editor selected } );
Bear in mind that these click events will always be triggered when you click on the buttons; when you click on the "Visual" button for example, the event will be triggered regardless whether the current mode is "Visual" or "Text". If you need to, you could easily tackle that by storing the previous state yourself. | stackexchange-wordpress | {

Hide meta box for everything BUT a certain custom post type

Add a static page that links to homepage
My home page is a dynamic page and on my navbar I have different static pages I want to add one to link to the homepage as if I clicked the logo. | To add a link to the homepage in your navbar, you can use the following function to add a link to the home page in `wp_page_menu_args`
function wpse01_home_link( $args ) {
if ( 'main-menu' === $args -> theme_location){
if (! isset( $args['show_home'] ) )
$args['show_home'] = _x( 'Home', 'homepage' );
}
return $args;
}
add_filter( 'wp_page_menu_args', 'wpse01_home_link' );

wp_insert_post removes information when updating
I'm using a front-end form and `wp_insert_post` to update posts from the front-end of a website - in order to do this I am using:
'ID' => get_the_ID(),
to make sure it is updating the current post (the form appears on the posts page). I am using the below to edit the post content:
'post_content' => $_POST['postContent'],
(this takes the result from a submitted form).
However, on save the information is submitted in to the post but all other post data seems to be reset such as the title and post password.
Is there any way to stop this happening? it seems like some very odd default functionality. | You are using the wrong function. `wp_insert_post()` is for creating posts. You need `wp_update_post()` if you want to update existing data. | stackexchange-wordpress | {

Uses Cases for the Calendar Widget
So I've looked at several themes and visited several theme dev sites and i'm confused about the "purpose" of the WordPress Calendar Widget.
So it states it is...
> A calendar of your site’s Posts
But really? Is that all it is used for? Surely there are more creative uses for this widget. Is anyone using it in any creative way?
**Edit**
The Question is - how you would modify the calendar widget to extend its functionality for custom purposes. | As it sits, the calendar widget pretty much does just what you've said—allows people to troll the archives.
Of course, it can be modified for different uses. One site I worked on used the Future plugin to convert the WordPress calendar widget into a calendar of events by creating a post for each event whose "date published" field was set to the date the event had happened in the past or would happen in the future. | stackexchange-wordpress | {

store custom WP table names in a global variable
I was being creative and put this in one of the files loaded with my plugin. Are there implications with storing the table names this way?
global $wpdb;
if(!defined('DB_ARTISTS'))
define('DB_ARTISTS', $wpdb->prefix . "artists");
if(!defined('DB_RELEASES'))
define('DB_RELEASES', $wpdb->prefix . "releases");
EDIT: I had originally not included all of the information I had meant to. Tables and variables are prefixed with ABC ( `ABC_DB_ARTISTS` & `$wpdb->prefix . 'abc_artists'` ). | The `DB_` constant prefix in WordPress is generally considered reserved for `DB_NAME`, `DB_HOST`, `DB_USER` and `DB_PASS`. Using it for plugin-specific constants is, in my opinion, not a great idea. The only implication it might pose is if other plugins try to use the constants, but that's purely theoretical.
The proper way to do this is to store the table names in the WPDB object stored in the global `$wpdb`.
global $wpdb;
if ( ! isset( $wpdb->myplugin_artists ) && ! isset( $wpdb->myplugin_releases ) ) {
$wpdb->myplugin_artists = $wpdb->prefix . 'myplugin_artists';
$wpdb->myplugin_releases = $wpdb->prefix . 'myplugin_releases';
}
It's important to use a proper prefix (in this case `myplugin_` for your plugin). For example, for Advanced Custom Fields, this is usually `acf_` (more on prefixing). | stackexchange-wordpress | {

It shows all the content | You can use the WordPress function `get_extended` to fetch the different parts of a string (the part before and the part after the `<!--more-->` tag). `get_extended` returns an array with three keys, of which the keys `main` and `extended` are important: `$arr['main']` contains the part before the more tag, and `$arr['extended']` the part after the more tag.
This would yield something like:
// Fetch post content
$content = get_post_field( 'post_content', get_the_ID() );
// Get content parts
$content_parts = get_extended( $content );
// Output part before <!--more--> tag

Hide the post count behind Post Views (Remove All, Published and Trashed) in Custom Post Type

So, resorting to `preg_replace`...
We'll need to filter the links, and it's good to see that you've already found the proper filters! Looping through the views and using a regular expression, we can remove the element containing the post count. Implementing this for posts, you'll need something like this:

function wpse149143_edit_posts_views( $views ) {

Show category post with excerpt text

Why use wp_send_json() over echo json_encode()?
When sending a JSON response back to an AJAX request, why use the WordPress function `wp_send_json()` and not `echo json_encode()`? What is the benefit of using the WordPress function `wp_send_json()` over `echo json_encode()`?
Ref: `wp_send_json` | `wp_send_json()` handles all parts of returning content in an AJAX call. First off, it sets the content type of the returned content to `application/json` with the proper charset. Secondly, it automatically calls `wp_die()` after sending the JSON result, which is necessary in an AJAX call in WordPress.
You could consider using `wp_send_json_success()` for successful requests and `wp_send_json_error()` for erroneous requests, thereby adhering to the WordPress standards for handling AJAX requests. These functions set a `success` (boolean) and `data` (any type) key in an array and encode that entire array, thereby allowing you easily check in a structured way whether the request was successful or whether something went wrong. | stackexchange-wordpress | {

ob_end_clean();

return $items;
}
When login is performed using this button, It should redirect the current page where login is clicked. How can I do that?
I think `wp_loginout('index.php')` needs to change because after login and logout I redirect to home page. What should I write to go previous page ? | `wp_loginout` accepts two arguments, `$redirect` (string) and `$echo` (boolean). You can specify the URL of the page to redirect to after logging in or out with the `$redirect` parameter. In your current code, `$redirect` is 'index.php'.
You can get the full URL of the current page by using
( is_ssl() ? 'https' : 'http' ) . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']

How to create .pot files with POedit?
I've spent hours today on what seemed like something really simple, which is to create a .pot file for a Wordpress theme that I'm creating. I've read the Smashing Magazine article, the Tutsplus article and few others on how to use Poedit to create .pot files for a theme, and then create .mo and .po files, but sadly, I'm still stuck at the first step.
I installed Poedit and I find that the UI is completely different than that is shown in all of the the tutorials and it seems like there is no more an option to create .pot file. Only thing that is available is to create .po and .mo files from an existing .pot file, which is not what I need now.

Is it wrong to use the English version of WordPress to server a site in a different language?
I'm building an online store for an Indonesian market, so the front-end must be in Bahasa Indonesian.
Will using the English version of WP, and a theme in English without .po files, introduce complications/errors/bad experience if the content is in Bahasa Indonesia? Ie. Incorrect language attributes. Or is it ok to use the English version of WP and fill it with content written in Bahasa Indonesia? | There is no technical problem in doing so, and there won't be any complications or errors.
However, it could be that not all content on the site will be in Indonesian. Some strings in themes and in other places in the front-end are outputted by WordPress, and as all strings are in English in WordPress by default, some content on your website might be in English.
Thus, if you don't rely on localization anywhere, there shouldn't be a bad user experience either.
A better solution, however, might be to change the locale depending on whether the page being served is front-end or back-end: Different Language for Frontend and Backend. | stackexchange-wordpress | {

How to make javascript work on theme options page
Gentlemen!
I'm composing a theme options page for my WP theme. And I bumped into the problem of finding the proper way to introduce inline jQuery interactions to the page.
Ideally for me in the situation will be inline jQ code
<script type="text/javascript">
$(document).on({
ready: function(){
alert('Hey!');
}
})
</script>
But this code fails because I guess the admin options page is rendered before the jQuery is included so js generates expected error. The same code with no jQ identifiers works ok means I get alert window when introduce:
<script type="text/javascript">
alert('Hey!');
</script>
Question is how to properly introduce inline js containing jQ (or any other framework) syntax and make it work? | The problem with your code is, as we found out in the comments on the question, that you're using `$`, which is either undefined or has a conflict (in any case, it's not pointing to `jQuery`).
