How to center a video
I can not center a video in a wordpress blog post. Here is the shortcode used for the video:
[video width="1920" height="1080" m4v="
It is an mp4 video file from my uploaded media. I have tried to add this to my style.css, and still did not work:
.wp-video {
text-align: center;
margin-left: auto;
margin-right: auto;
}
Any help please.... | To center an element, you will also have to style it's parent element too. So let's say, you video has a structure like this:
<div class="parent-class">
<video class="wp-video">
</video>
</div>
To center the video, you will have to give it's parent a width. Using:
.parent-class{
width:100%;
display:block;
}
Now, you can use this to do the final touch:
.wp-video {
text-align: center;
margin: 0 auto;
max-width: 400px;
display: block
}
Notice that you have to define a width for this video, since your video has a width of 1920px, which for sure will overflow most of the screens. | stackexchange-wordpress | {

Exclude parent with child pages from WP_Query
How can I query only those pages that **DO NOT HAVE** child pages?
E.g.:
* Parent page 1
* Child page 1
* Child page 2
* Parent page 2
* Parent page 3
* Child page 1
* Child page 2
* Parent page 4
I would like to show
* Parent page 2
* Parent page 4
$newQuery = new WP_Query( array (
'posts_per_page' => -1,
'post_type' => 'page',
// Solution?
) );
`
Thanks | the_dramatist's answer will give you only top-level pages that have no children, which matches the example given in your description.
However, if you want to get ALL leaf pages, use the following:
SELECT *
FROM $wpdb->posts
WHERE
post_type = 'page' AND ID NOT in
(
SELECT ID
FROM $wpdb->posts
WHERE
post_type = 'page' AND ID in
(
SELECT post_parent
FROM $wpdb->posts
WHERE post_type = 'page'
)
) AND post_status = 'publish' | stackexchange-wordpress | {

Wordpress categories being called "archives" in google links. How to remove?

Is it possible to prevent website from breaking with auto update?
Recently i've noticed a lot of posts from users, complaining about their website running into problem after updating the WordPress to the latest version.
Let's say i have a website with a lot of custom functions and codes, which depends on the current core to run. The functions are too many to watch, maybe 30 or more, and WordPress is releasing update every once in a while.
So, how can i leave the auto update to ON and be sure that this feature won't break my Blog? I know i can make backups regularly, but this is not an actual salvation.
The path notes may be helpful, but still, on custom templates it's a pain to check it every time an update is release.
Now what are my choices? Do i have to turn the auto update OFF and backup / update manually? Or is there a way / plugin / etc. to prevent such things from happening? | A website is just like any other software product, any change need to go through QA stage first, no matter how trivial it might seem. This is why you should always test all updates on a staging/dev server before pushing it to production.
As always it comes down to a question of ROI. Simple blogs can suffer down time for days while a fix is being work on, while sites that generate 1000$/hour probably less tolerant to hiccups, and the time invested in proper QA to avoid it is totally worth it.
So it is your judgment call in the end of how bad will it be for you if an update will break you site. If you value your time in lets say 40$/hr and the site generates 5$/hr, it is just not worth it for you to have a 3 hours QA cycle on the bi-monthly update release (not official but this is the real life rate), especially if you don't have any bad hacks in your code and it should in theory be "future prof" | stackexchange-wordpress | {

How to delete a theme using AJAX

I've looked through the `ajax-actions.php` file and saw this: `wp_ajax_delete_theme()`, but how do I trigger it?
I want to add this 'delete theme' function to my WordPress plugin.

echo '<input type="submit" value="Delete TwentyThirteen Theme">';
echo '</form>';
You can replace the hard-coded `slug` input field with a `<select>` one and loop through installed themes to add them as the select options if you like, but I've given it this way because you say you want to delete _a_ theme. | stackexchange-wordpress | {

Remove current_page_parent from posts page link in WordPress nav menu
I have set a page to be the posts page. So when I visit single posts the link for posts page in nav menu has a class 'current_page_parent'.
But when I visit single posts for a custom post type, then also it is adding 'current_page_parent' to the link for posts page.
How can I restrict it and not add the class when I visit single custom post types page. | I assuming you're using wp_page_menu() or wp_list_pages(). If so, then what you need to do is hook into the page_css_class filter, e.g.,

function
my_func ($classes, $page, $depth, $args, $current_page_id)
{
if (/* test condition */) {
$classes = array_diff ($classes, array ('current_page_parent')) ;
}
return ($classses) ;
}

wp_set_object_terms not accepting variable array
I am trying to use the following command:
wp_set_object_terms( $myID, $myissuearray, 'my_issues', true );
But for some reason, it won't accept my variable array.
That array, `$myissuearray`, using `error_log(print_r($myissuearray,true))` outputs:
Array
(
[0] => 9
[1] => 10
[2] => 77
[3] => 12
)

If on the other hand, I don't use my variable and set the issue array by hand in the command to something like:
wp_set_object_terms( $myID, array(9,10,77,12), 'my_issues', true );
the command works and the terms are set. I am stumped as to what I am doing wrong. Why won't this command accept my variable array?? | Ok, so it turned out that my array was an array of strings somehow, which using var_dump (instead of print_r) revealed. Then I needed to convert my array to int values, which I did thus:
$myissuearrayINT = array_map('intval', $myissuearray);
And now, when I do the following it works as expected:
wp_set_object_terms( $myID, $myissuearrayINT, 'my_issues', true );

Pulling Data from CSV vs. pulling data from database
I developed a custom post type with a custom taxonomy for my WP theme and I need to add a number to associate with my taxonomy.
Example: The taxonomy is "store" and the average savings for that store is "20".
I created an interface to add average savings while creating and editing the taxonomy. The number is stored in wp_options table for the particular taxonomy ID. On the other hand, my colleague created added a CSV file in the root directory and wrote a function to open the file and fetch the number according to the taxonomy name, every time a taxonomy page is loaded.
I just need to know which is the best method to do this and why? | Reading, searching and closing a file every time the page is loaded is highly time consuming. Database systems are highly optimized for reading and writing huge amount of records, querying data, providing schemes, relations between the data etc.
What will happen if 10K users hit the taxonomy page? How you will handle the updates of a taxonomy or the insertion of a new one in the file? How you can do efficiently queries regarding the value saved in the CSV file? What will happen if you delete the taxonomy or if the file has 1 million records?
**The proper way is to save it in a database.**

Page Revision date displaying on google search

How to display author above content-single.php post

MathJax inside shortcode
In my custom theme I included some shortcodes. One of them is called `[alert]...[/alert]` and results in a bootstrap alert box. It accepts a type (warning, danger, info or success), a title and the main content. The output is a simple return:
return '<div class="alert alert-' . $atts['type'] . '" role="alert"><p class="alert-title">' . $atts['title'] . '</p>' . $content . '</div>';
I need to wrap an important math formula by one of these alerts, so I wrote:
[alert type="warning" title="Important Formula"][latex]a^2 + b^2 = c^2[/latex][/alert]
But this outputs:
<div class="alert alert-warning" role="alert"><p class="alert-title">Important Formula</p>[latex]a^2 + b^2 = c^2[/latex]</div>
So the mathjax latex shortcode is not being recognized and thus is not translated into a mathematical formula. Outside the alert shortcode they are translated into a formula.

Newline URL entity when using esc_url()
Is it possible to set a newline character `\n` as a URL entity when using `esc_url()`? The URL entity for a newline is `%0A` as mentioned here: <
But `esc_url()` strips out the `%0A`.
Any help appreciated. | # Background:
WordPress strips out `%0A` from URL because in general newline has no practical purpose in URL. Unless it's a `mailto:` protocol, WordPress strips out `%0A`.
So it's better not to use them in URL at all.
# Solution:
Still, if for any specific purpose you have to use `%0A`, you may use `%250A` and then filter it back to `%0A` using `clean_url` filter.
> `%250A` is URL encoded version of `%0A`, i.e. double URL encoded version of `newline`.
You may use the following CODE for filtering (in a plugin or in your active theme's `functions.php` file):
add_filter( 'clean_url', 'double_encoded_nl_to_encoded_nl' );
function double_encoded_nl_to_encoded_nl( $url ) {
return str_ireplace( '%250A', '%0A', $url );

How to link to a custom .php page in my folder
I have created a custom page that I have called mypage.php.
It is in my template folder with al the other pages (index.php, page.php, ...)
I want this page to be opened when i click on the below code.
<a href="<?php site_url(); ?>/mypage.php">Go to page</a>
When I click on the link the url in my browser look like: < which I guess is correct.
BUT it uses index.php as template ignoring the code I have into mypage.php
So all i am getting at the moment is an empty page with only my header and footer.
Is it possible to use pages in this way with Wordpress? I had a look online and on this site but I haven't been able to find a solution for this problem. | WordPress doesn't load templates that way.
# First: give the template a name:
To load a page template, first you'll have to make sure your template has a name. To do that, you'll have to have the following CODE in your template file (here `mypage.php`):
<?php
/**
* Template Name: My Page
*/
Once you have the above PHP comment, WordPress will recognise it as a template file.
# Then, assign the template to a page:
Now you'll have to create a WordPress `page` (from `wp-admin`).
While you create the `page`, WordPress will give you the option to choose a custom template (if there is one). After you choose the template and `Publish`, that page will use your `mypage.php` file as a template.

Changing permalinks structure without loosing SEO
Current structure is `/%year%/%monthnum%/%postname%.html`
Desired structure is `/%postname%/`
Since we are already positioned with urls like `domain.com/2015/04/example-post.html`, we want people to be redirected to `domain.com/example-post/`.
I already tried installing some plugins, like **Simple 301 Redirects** , which looked good since it seems to work with rules as shown in the image below:
\.html$ /$1 [R=301,L]
Where
* `[0-9]+/` is the numeric year and month
* `(.*)` is the part we'll use below (`example-post` in your case)
* `/$1` is the part we've got from the above
301 redirect is completely perfect for SEO. | stackexchange-wordpress | {

Restrict partially matching usernames
I've been looking and looking for a solution for my problem but i have been unable to find anything.
I have found a plugin that allow me to restrict certain usernames, I found even a function but there is nothing that allows me to restrict partially matching usernames, there is nothing to prevent users to register under names like "joeadmin" or "seanadmin" and etc.
Is there anything that can be done to prevent users to register anything that contain "admin" and other prohibited words? | There's a `validate_username` filter hook that is used by `validate_user()` which is in turn used by `register_new_user()`.
So you can disallow usernames containing `admin` or other prohibited terms:
add_filter( 'validate_username', 'wpse257667_check_username', 10, 2 );
function wpse257667_check_username( $valid, $username ) {
// This array can grow as large as needed.
$disallowed = array( 'admin', 'other_disallowed_string' );
foreach( $disallowed as $string ) {
// If any disallowed string is in the username,
// mark $valid as false.
if ( $valid && false !== strpos( $username, $string ) ) {
$valid = false;
}
}
return $valid;
}
You can add this code to your theme's `functions.php` file or (preferably) make it a plugin.

How can I include a query string with get_permalink
My login link uses `wp_login_url( get_permalink() )` so that the user is redirected back to the page they were viewing, and not to the dashboard.
However, this does not include query strings. So if a user was at `here.com/?page=4` they would not be redirected back to page 4.
How can I include the query string in my code?
$items .= "<li class='menu-item'> <a href=\"".wp_login_url( get_permalink() )."\">Login</a></li>"; | You can use add_query_arg() to add any query parameters you want to a URI, e.g.,
$redirect_uri = add_query_arg ('page', '4', get_permalink ()) ;

Or, you could simply use `$_SERVER['REQUEST_URI']`, which will already contain any query string present in the current page's URI, e.g.,

Is it possible to restrict viewing of category PAGE to logged in users only?
I want to block the category page so that only logged in users can view the category page. I'm not talking about the posts in the page, I'm meaning the actual page view.

Dynamic name of cron event

Skip file when plugin updated
Is there a way to keep a constant file in my plugin directory so that it doesn't get updated? I'm a developer and would like to have a file for users to add custom functions to in my plugin. When they update the plugin, that file should not be updated if it already exists. Is this possible? | On you future code files in your plugin, do not include the 'option' file in the repository. Since it is not included in the repository zip, the file (if it exists) will not be overwritten on the user's system.
You may need some code in your plugin to create the file on activation with some default values, if it does not exist. That will ensure that the file will be there for the end user.
Although I am not a fan of letting users create files in the plugin area. It would be better, I think, to create an options page in your plugin that would contain the values (constants?) needed by your plugin. And your plugin would probably need to create those constants if they do not exist. (Remember that constants are 'constant', and cannot be redefined.) | stackexchange-wordpress | {

Redirecting all posts after changing URL structure with htaccess
I am looking for the `.htaccess` regular expression that would redirect the old structure to the new one, the reason i don't want to use plugins is they often have unexpected results when WordPress updates or the author abandon them, I need something that would 301 redirect for a long time reliably.
Old permalink:
New Permalink:
**Note:** I am not sure if the rule should consider this but. I also use custom post types which add their slug to the url. So The "category" shows up for normal "post" but on CPT it's just:
I suspect a good rule could work for both cases since /%category%/ and /%example-cpt-slug%/ are _something between_ "/ /".
What I'm not so sure is how can you specify the POST ID (%post_id%/) as a target. | Within Settings > Permalinks your Custom Structure was set to `/%category%/%postname%/` right?
Now you want to set (or you've already set) to `/%post_id%/` right?
As far as I know (and I've also tested) WordPress will 301 redirect all of your posts (from the post type 'post') to your new Custom Structure. You won't need to do a thing.
So if you've set the Custom Structure to `/%post_id%/` it means that if someone accesses the URL ` they would be redirected to `
After you've changed your Custom Structure even if you also change your post slug WordPress will still redirect it correctly.
I don't know from which WP version this is supposed to work, but just for the record, I've tested within 4.7.
If it's not working for you let me know and I'll give you another solution.

Customizer: widget-synced triggers twice
I just noticed that `widget-synced` is triggered twice when you're trying to edit a widget, click on a text field, write something, triggers `widget-synced` once and after that, if you click anywhere else it triggers a second time.
![enter image description here](
Is this default behavior and can it be prevented in a custom widget?
Thanks!
Pinging @WestonRuter | The reason for this is that the widget will run its update logic on `keydown` _and_ also on `change` for a given `input` element. See <
There are some tradeoffs made when widgets were added to the customizer to bring these PHP-driven interfaces into a JS-driven context. It wasn't perfect and so this is part of the reason behind the JS Widgets feature plugin, to modernize how custom widgets are implemented in the customizer.
If you want to really just listen for when a widget actually changes its state, you can listen for the control's underlying `setting` change instead. The setting will only be updated once after a given `keydown` and subsequent `change` event. | stackexchange-wordpress | {

Should a WordPress plugin polyfill the global JS environment?
I'm building a JS-heavy WordPress plugin with babel/WebPack to transpile ES6 -> ES5 code. I'm also relying on some of the new features, like `Promise` and `Object.assign`, and I'm wondering a few things:
1. Does WordPress ship any polyfills of its own for the global environment?
2. What are best practices around handling/shipping polyfills in WordPress plugins? | > Does WordPress ship any polyfills of its own for the global environment?
No, as far as I remember WP core doesn't ship with any polyfills.
> What are best practices around handling/shipping polyfills in WordPress plugins?
The typical practice for JS in public WP extensions is to either:
1. stick with core–provided scripts/environment;
2. isolate your code and dependencies from impacting global state, by use of noConflict modes or otherwise.
If you _have_ to deal with global state in public extension — be prepared for it to explode in most peculiar ways out there in the wild. | stackexchange-wordpress | {

above paragraph is quoted from WP Codex.
so you cannot use this hook to get older value because it fires after saving new values to DB. WP has another action hook named `wp_insert_post`but sadly this hook does same thing as `save_post`
alternatively you can use Filters to get the job done. WP provides few filter to edit the post while saving or before saving to DB. like `wp_insert_post_data` & `content_save_pre` might work for you, i think.

} | No you don't need `esc_attr()` function to print out fixed static text.
You only need it to print out dynamic or generated text, so that if the attributes have any special characters that may break your HTML, `esc_attr` will escape that properly.
In your particular case, you can just write:
echo '<label><input type="checkbox" id="custom_header" name="custom_header" value="1" '. $checked .'> Activate Custom Header</label>';
However, if you had any generated or user input text, then you should've used `esc_attr()`. For example:
$style = "__Some generated text from database or user input__";
echo '<label><input type="checkbox" id="custom_header" name="custom_header" value="1" '. $checked .' style="' . esc_attr($style) . '"> Activate Custom Header</label>'; | stackexchange-wordpress | {

php syntax - how to concatenate properly - echo bloginfo('stylesheet_directory)
This is driving me batty. Is my syntax wrong? Why is the first "." in my img src call throwing out an error? This works if I put a hard link in the img src call, FYI.
<a class="blog-image" href="<?php the_permalink(); ?>">
<?php if (has_post_thumbnail() ) {
the_post_thumbnail('medium-size');
} else {
echo '<img src="' . bloginfo('stylesheet_directory'); . '/img/ogpimage.png" alt="Blog Posts Placeholder">';
} ?>
</a> | 1. `bloginfo()` does already an `echo`. It will be printed before everything else in your `echo` statement. Use `get_bloginfo()` instead.
2. `stylesheet_directory` is one of these arguments where it is better just to use the function that is called by WordPress: `get_stylesheet_directory_uri()`. It is easier to understand, especially in this case where one could expect a path by looking at the name of the argument string.
3. If you are using an URL provided by a WordPress function, **escape it**. Always.
4. For better readability, I would use `printf()` here.

What is the most idiomatic way to let clients edit phrases in HTML?
I added HTML banners to the top of certain pages on a client's site. He wants to make edits to the text phrases on these banners without having to edit any HTML. How do I open this up for him?
* * *
In the past, I have simply made a collection of pages that I insert into my HTML banners using the following code:
<div class="banner-top">
<h1><?php echo $about_us_phrase->post_title; ?></h1>
<p><?php echo apply_filters( 'the_content', $about_us_phrase->post_content ); ?></p>
</div>
But this feels hackish, especially because it forces the client to swim through a potentially large number of pages to find the one that corresponds to the text they'd like to edit.
What is the most Wordpress-y way to do this? | Are the banners related to each page? If so, I would use a custom field or just a metabox that the user could edit or enter information into on the page that you want the banner to show up. The field would show up below the content in the page editor. You would then in your single.php add the code you noted above to encase whatever is typed in the custom field.
If the banners are NOT related to individual pages. I would make a custom post type "banners" and then have them randomly show up on pages by inserting a call for the CPT within the single.php.
You can either use a plugin to create the fields or these reference links will help you get started on creating your own:

Exclude current post for custom post type
What I need: show random post except current post for custom post type `Question`
In below codes, the exclusion doesn't works. It simply show any post including current post.
<?php
$my_query = new WP_Query( array('showposts' => '8', 'post_type' => 'question', 'post__not_in' => array( $post->ID ), 'orderby' => 'rand'));
while ( $my_query->have_posts() ) : $my_query->the_post(); ?>
<a href="<?php the_permalink(); ?>"><?php the_title() ?></a><br>
<?php endwhile; ?>
If I change the `Question` to be `Page`, it works for Page. If remove the `Question`, it works for Post.
I guess it must be something I missed if I want to make it works for custom post type
**Update:**
Previously I wrote `Question` now changed to `question`, but still results the same | You should use `get_queried_object()` or `get_queried_object_id()` to get the current custom post's ID. IMO `get_queried_object()` is a better choice here as you can conditionaly check for the post type also. Try this
function wpse258217_random_posts() {
$obj = get_queried_object();
if ( $obj->post_type === 'question' ) {
$postid = $obj->ID;
$my_query = new WP_Query( array('showposts' => '8', 'post_type' => 'question', 'post__not_in' => array( $postid ), 'orderby' => 'rand'));

Instructure Canvas API with Wordpress
My client has an account on Canvas LMS where he is running his institute, he wants a wordpress website that should be connected to his canvas LMS account and he should be able to handle requests from his website, like if a user, after logging in, changes something in his profile then it should changed in the main application (canvas LMS) too, he should be able to edit courses, view courses etc on his website. I am not sure from where to start this, I have searched the internet but couldn't find anything relating Canvas LMS API with worpdress. If someone can point me in the direction from where to start that would be a huge favor. I am new to APIs with wordpress and dont know how to authenticate or get access token and then how to send requests to the API using wordpress.
Thanks in advance | Generally speaking, you will need to create a plugin to accomplish the connection and manipulate data. It looks like Canvas uses JSON in their API. There is a good overview of handling JSON in PHP \- the rest you will probably need to piece together from Canvas's API documentation. Before you get started, make sure both sites are running over HTTPS so you don't expose any sensitive information.
Since there are no Canvas-to-WordPress-specific tutorials available, you might also find it helpful to go through Google's OAuth 2.0 tutorial for practice in connecting using OAuth, and then work on connecting to Canvas. In my experience connecting is the hardest part. From there, piecing together requests becomes easier.
Out of curiosity, why is the client asking you to build a WordPress site that manipulates Canvas data? I work in higher ed and would love to hear more about their use case. Are they trying to provide a different front end for faculty? | stackexchange-wordpress | {

Use .php file as page instead of wordpress page & template file?

{
if (get_post_meta(get_the_ID(), 'usercp', true) === 111) {

Where does Yoast SEO plugin sets the site/page title?

One of my plugins broke when I tried to update it, how do I safely uninstall it?
I recently tried to update Yoast SEO to its most recent release (4.3). My site is running the most recent version of WordPress (4.7.2).

error: tried to create a directory that already exists
