List custom post types in metabox
Is there a function to list all custom post types in a metabox?
I have
wp_list_pages( $args );
to list the pages in metabox but now I need also to list all custom post types.
Thanks for advices | <?php
$args = array(
'public' => true,
'_builtin' => false
);
$output = 'names'; // names or objects, note names is the default
$operator = 'and'; // 'and' or 'or'
$post_types = get_post_types( $args, $output, $operator );
foreach ( $post_types as $post_type ) {
echo '<p>' . $post_type . '</p>';
}
?>

How can transfer get so large when exporting data (15-16MB to over 10GB)
When I try to export a database throught **Wordpresses export-function** (database = about 15-16 MB), I get this in the xml-file created (that is 1kb):
**Fatal error** : Allowed memory size of 100663296 bytes exhausted (tried to allocate 45481985 bytes) in row 2935 in functions.php. The limit of transfer is 10GB on the webhotel (space2u). But how could the transfer be so large?
Line 2935 is inside a function that is hooked by:
add_action( 'post_submitbox_misc_actions', array($object, 'callback-function') ); | You seem to be confusing different things. I am not sure what precisely you mean by "transfer" (monthly bandwidth? disk space?), but 10GB figure likely isn't about _memory_ (RAM).
Error you are getting _is_ about RAM. 100663296 bytes corresponds to just 100MB. That much is _typically_ enough for average WP install to function, but might not be enough for some specific functionality or third party code. I think the highest WP tries to request natively is 256 megabytes when manipulating images.
You should inquire with your hosting about RAM available and configuring it to higher value. If that is highest you can get you might not be able to do resource–intensive operations. | stackexchange-wordpress | {

How to get DEFER or ASYNC attribute to appear when I add a stylesheet with wp_enqueue_style from a plugin?
Almost all of my CSS and JS resources can be postponed with an ASYNC or DEFER tag added to the resource. This may improve performance of my page load times considerably.

return $url;
}

Best way to modify a plugin with no hooks and no pluggable functions?
I have to make some changes to some functions in a plugin that don't have hooks and aren't pluggable.
My idea was to wrap the functions I modify in a `if ( ! function_exists())` and move my modifications into a separate plugin. Then whenever I need to update the plugin, I just re-add the `if ( ! function_exists())` wrapper.
Please tell me why this is a bad idea and what I should be doing instead. | It seems like the plugin you are using are quite important to you and/or your client, and the plugin itself is most probably regulary updated with proper support.
I would definitely contact the author and discuss possible changes to the plugin. If a change is a constructive change and would bring some degree of usefulness to the plugin, I see no reason why the author would not implement your changes in the near future releases/updates.
Primarily, if your change is to out of scope of the current plugin, you can suggest and ask the author to just add a proper filter where needed in future releases/updates.
But yes, I would start at the plugin author for such kind of support before looking into other solutions | stackexchange-wordpress | {

Creating a search with tag variable also added for more detailed results
Wordpress search results is definately not the best indexing and search function we have seen.. If adding multiple tag variables in the search in order to get a more precise result work?
For example:
Default search query: `www.example.com/?s=kidsbook`
What if we spiced it up a bit adding: in the search some more tags that the results must have (for example female author and bestseller). So that only post results of kidsbook AND from those results only the best sellers of female authors.
would the bellow example work?
www.example.com/?s=kidsbook&tag=femaleauthor&tag=bestseller
Would the search accept both tags?
Last question would this type of search cause a much greater load on the server?
Thanks for your answers. | Add a new input to the form, the name is key, you can easily access query vars that match a paremeter supporter by WP_Query using the function `get_query_var`.
For example, you could try to generate an URL like this:
And with `get_query_var(tag)`, you get the values, and the you create a custom `WP_Query` using that parameters.
$query = new WP_Query(
array(
's' => get_query_var('s'),
'tag' => get_query_var('tag')
) );
One thing you have to take into account is that can't have the same parameter twice in the URL, well, you can, but you can't use the `get_query_var` function to get the value.
You can use jQuery to get the selected options from a `select` element with the `multiple`attribute, and pass the selection to an input with the name "tag", there are other workarounds for this.
The query wont affect performance that much.

Adding Font Awesome to WP Plugin
I'm trying to use font awesome icons for my plugin. I've read this page in the codex and this question.
Here's what I've tried so far:

>
> add_action( 'wp_enqueue_scripts', 'wp_styles' );

> wp_register_style( 'font-awesome', plugins_url( 'wp-plug-in/css/font-awesome.min.css' ) );
> wp_enqueue_style( 'font-awesome' );
> }

> `<i class="fa fa-twitter"></i>`
But to no avail. It doesn't display anything at all. I know I'm missing out something and I'm hoping that someone could point it out and probably give me additional resources.
Thank you.

It turned out the theme I had activated didn't have `<?php wp_head(); ?>` on the header.
Lesson learned. :) Thanks a lot @Robert and @Abhik. | Did you create `wp-plug-in/wp-plug-in.php` file in plugins folder and added this following code.

How to manage hundreds of WordPress sites?
I am managing 100+ WordPress sites in a single multisite install. The sites are completely independent (i.e. the site's owners do not know that they are hosted on the same server). So far the multisite has served me well in maintainability (just one server to access to, one WordPress install, a single copy of each plugin, ...).
There are problems, though: with multisite the user base is shared between all sites (it's a _network_ , after all), so that if a user sign up on a site, she can't sign up on another site with the same email; and I need the site admins to not know that they are inside a multisite.
Is there a way to make the multisite user register with the same email on different sites?
If not what's the best way to manage this use case?
As an alternative I have thought of making multiple WordPress installations, symlinking the plugin folder (WP 3.9+) and using something like InfiniteWP to manage the sites. | There is a plugin for this: Join My Multisite
> Allow site admins to automatically add existing users to their site, or let users decide at the click a button.

>
> * Auto-add users
> * Have a 'Join This Site' button in a widget
> * Keep things exactly as they are
> * Create a per site registration page
> * Use a shortcode to put a 'join this site' button on any page/post.

Get all pages and posts with get_pages() or get_posts()
Trying to get all posts (with all I mean all pages, posts and posts from custom post types).
Is this possible? The documentation says I can only pass a string as `post_type` so how can I get all pages and custom post types?
Example where custom post type is called `project`

'exclude' => $inclPages,
'post_type' => 'pages,project',
'title_li' => __(''),
'sort_column' => 'menu_order'
);
$pages = get_pages( $args );
Any advice would be appreciated | `get_pages` does not work with posts or post types that is not hierarchical like pages, so if your post type is hierarchical like posts, it would not work
> This function can also retrieve other post types using the 'post_type' parameter, but the type must be hierarchical like pages, or the function will return false.
If you need all post types to be returned, ie all `post`, `page` and custom post types, just pass `any` to `post_type` in either `get_posts` or `WP_Query`, the choice is up to you | stackexchange-wordpress | {

How to query authors by custom taxonomy?

B. "Share this - with the icons inline with comments - Now we have it centered above the comments with the jetpack plugin.
2. Above the entry title i want do display which category the post is displayed in. So its displayed first with category, then title and last the time.
3. I also wants configure the time of the day in the time data. So it should be displayed like "16:45 | september 16, 2014" | If you don't want to use twentytwelve_entry_meta(); in the post loops that calls the date, category and adds that "This post was posted in" text itself, then you'll have to remove it and re-write from scratch.

<?php comments_number( 'No Comments', 'Comments: 1', 'Comments: %' ); ?>
1B: If this is coming from Jetpack, it will automatically place them for you. If you want to change where they appear, take a look at this topic: <
2: To show the current category(ies) that your post is in, refer to the the_category function: <
3: To change the format of the date, refer to the get_the_date function: <

Where to use $post global variable?
I am confusing to use `$post` global variable. Is it use inside loop or outside loop? What is the advantage to use it inside and outside loop? | The `$post` global is set by `$wp_query->the_post()`. As `$post` is set by the main query and the fact that templates are set within the global variable scope, it is available throughout the template, so there is no need to explicitly calling the `$post` global when you are within the specified template as the `WP_Post` objects can be accessed any where. You can access the `WP_Post` objects by just simply calling them directly, for example `$post->ID` to retrieve the page ID on a page template
When you need to access post data outside of a template, for example, in a function or in a widget, you need to call the `$post` global to make the post data available for use. | stackexchange-wordpress | {

Serializing User Role for update_user_meta

How do I 'rebuild' the WordPress Media library after transfer to new host?

UPDATE wp_posts set post_content=REPLACE(post_content, 'mysitexyz.net.basepointsite.com/', 'mysitexyz.net/');
What is the correct way to re-associate these images and have them appear correctly in the media library? | There's a few plugins to fix this, but basically it your database still references the images to be "oldsite.com/wp-content/uploads/" and you need it to be "newsite.com/wp-content/uploads"

UPDATE wp_options SET option_value = replace(option_value, ‘ ‘ WHERE option_name = ‘home’ OR option_name = ‘siteurl';

It will look for a string starting with `style="` and containing any number of characters until it hits another double quote `"`. (That would be an inline style applied to an HTML element). You'll "replace" it with an empty value (to delete it).
You can also test your content / regular expression with Regexr to ensure the one I gave you will work.

Debugging a redirect loop affecting only certain pages
I am trying to fix a site which has several redirects that seem to have been added via a plugin called Peters plugin redirect. The plugin has since been deactivated and delated but the redirects loop is stil present. I have tried the following:
* deactivating and deleting the plugin
* refreshing the permalinks
* clearing and resetting the htaccess defining the home and site url in wp-config
* deleting the rewrite rules in the options table
No caching plugin is being used and the problem remains in Private browsing mode. The only two pages affected are the home page and the registration page.
I would appreciate any ideas on how to resolve this or any suggestions on how to go about debugging.
EDIT: I found this which might have something to do with the issue as the site owner likes to use capital letters. | Turned out to be cacheing problem.

How to change home page only in WordPress
I am a newbie in WordPress theme development. I have a WordPress site on online. I create a new home page for my wp site and I want to use it my wp site instead of old home page.

add_rewrite_rule on multisite doesn't work
I define a rewrite rule on an init hook like:
add_rewrite_rule( 'foobar/(abc|def|ghi)/(.+)(/(\d.+))', 'index.php?my_action=$matches[1]&my_name=$matches[2]&my_version=$matches[4]', 'top');
This works with following URL on a single WP installation:
However it doesn't on a multisite installation.
It seems there's problem with rewrite rules on multisite an there's ticket #19896 which describes a similar problem on "non WP rules"
I have no idea what I should add to the `.htaccess` file and I prefer a "proper" solution.
**EDIT:**
I have forget something important:
I'm using WordPress MU Domain Mapping to use different domains and while the network is on `network.example.com` the site I use `add_rewrite_rule` is sub.example.com | It seems the problem is not with `add_rewrite_rule` rather with the `.htaccess`file for the multi site.
One of the test addresses was
Here's a part of the htaccess which causes the result (Line 2)
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
If I comment this line out it works as expected but it may break other thing. So you have to add your own rule **above** the latest block:
RewriteRule ^([_0-9a-zA-Z-]+/)?foobar/(abc|def|ghi)/(.+)(/(\d.+))$ index.php?my_action=$2&my_name=$3&my_version=$5 [R=301,L] | stackexchange-wordpress | {

How to Determine a Post's Last Edited Date?
I'm writing a little extract script to do a DB pull. I've been asked to get all restaurant posts (custom post type) that are among the 1000 top hit, OR have been added or edited in the last 3 years. OK, so I've got the 1000 top hits done through an export from Google Analytics. Then I did a SQL extract like so:
SELECT p.ID, concat(' p.post_name)
FROM wp_posts p
WHERE p.post_type = 'restaurant' AND p.post_status = 'publish'
AND p.post_modified < DATE_SUB(now(), INTERVAL 36 MONTH);
I thought I had it licked. Then the users looked at it, and found some restaurants that I thought were outside the 3 yrs, which were in fact _inside_. On investigation, I found it was due to **revisions**. :(
So, what is the best practice for determining last edited date, taking into account revisions? | If I got your question right, and you want posts created/modified between 3 years ago and today, try this query:
SELECT p.ID, concat(' p.post_name)
FROM wp_posts p
WHERE p.post_type = 'restaurant' AND p.post_status = 'publish'
AND p.post_modified > DATE_SUB(now(), INTERVAL 36 MONTH);
Because your `DATE_SUB` returns something like this: NOW - 3 years, so, it's something along the lines of `2011-09-20 12:21:41.000000`, and you are using a `<` sign, so you are checking for post that were created or modified before that date, so instead of getting the post created/modified between 3 years ago and today, you are getting the post created/modified more than 3 years ago.
Also, you aren't getting revision, because as you specify the `post_type = 'restaurant'`, and revision have a `post_type` called `revision`, you are just getting the post that belong to the custom post type you specified. | stackexchange-wordpress | {

Stop Wordpress processing Javascript as text
I'm currently developing a bus route planner, using Wordpress as my CMS. I've added some JQuery code to add support for ajax (so visitors can use the route planner and load the route without having to go to another page), but it's not working.
On closer inspection using Chrome's Inspect Element, Wordpress appears to be adding paragraphs to the Javascript code, although the Javascript code is properly configured and is recognised as such:

Why is Wordpress doing this, and how can I stop Wordpress from adding paragraphs to the code?

Anything you put through the post editor will get run through `wpautop()` before output, which is what adds the paragraph tags -- even if you enter it via the Text mode. I'd suggest outputting your JavaScript via a hook on the page instead of via the post editor.
Something like this:
/**
* Output JS to the page head.
*/
function output_head_js() {
?>

$( ‘#gosearch’ ).click( function() {
…
});

What is the earliest hook to modify post content?
I have installed a plugin that adds stuff at the end of the content. I just want to apply my modifications to the post content before this plugin does.
In my case or otherwise, what is the earliest hook that can be used to modify post content even before `the_content` filters are applied? | When two or more filters are hooked to the same filter hook, the conflict is resolved as follows:
1. If the filters are hooked with a `priority` parameter, the filter with a lowest value for the priority will be executed first. If no priority value is supplied, the default value is taken as 10.
2. If two or more filters are hooked with the same priority, the filter that was hooked first will take priority.
Eg.
add_filter('the_content','filter_1',5);
add_filter('the_content','filter_2');
add_filter('the_content','filter_3');
add_filter('the_content','filter_4',1);
In the above example, `filter_4()` will be called first, followed by `filter_1()`. `filter_2()` and `filter_3()` have same priority ie. 10. Hence, `filter_2()` will be called next because sequentially, `filter_2()` was added before `filter_3()`. And of course, finally `filter_3` is called.

Regardless of how you are adding a colorbox or what plugin you are using, assuming you added it by adding a field in your options table (as provided in the link), you can use the color value anywhere in your template files with a call to `get_option`:
$options = get_option( 'my-theme-options' );
$bg = $options['background'];
For example, as mentioned here, to colorize your first level headings add the call in your `wp_head` section.
function my_wp_head() {
$options = get_option( 'my-theme-options' );
$color = $options['color'];
echo "<style> h1 { color: $color; } </style>";
}
add_action( 'wp_head', 'my_wp_head' );

{
extract(
shortcode_atts(
array (
'form' => 0,

Post thumbnail height problem
I am trying to create a square thumbnail with auto crop with size of 300px 300px. I only get the width of 300px but the height is auto, i think is not cropping.
I tried this:
add_image_size( 'custom_image_size', 300, 300, true );
the_post_thumbnail('custom_image_size');
and this
set_post_thumbnail_size( 300, 300, true );
the_post_thumbnail();
but i get the width 300px and the height is auto. I also tried to Regenerate Thumbnails by using a wordpress plugin. So what should i do to get the thumbnail 300px with 300px ?
Images have dimensions: 1600 × 1200... so the images are bigger then 300px in width and height. | So i followed this link how-to-get-larger-images-in-a-wordpress-gallery and i changed the Thumbnail size to 300px with 300px from SETTINGS -> MEDIA, and then run a Regenerate Thumbnails.

If logged in user meta is
I was wondering if it's possible to display certain content _if_ a user meta field is set to a certain value.
The most related thing I could find is get user meta, however it seems to get the user meta from the author of the page/post, and not from the logged in user - correct?
Appreciate any hints - cheers! | No, not correct - `get_user_meta()` returns meta data based on the `$user_id` parameter you provide. You can combine it with `get_current_user_id()` to check if an user is logged in and than - if so - get the post meta. E.g. like this:
$curr_user_id = get_current_user_id();
// the value is 0 if the user isn't logged-in
if ( $curr_user_id != 0 ) {
// we know now the user is logged-in, so we can use his/her ID to get the user meta
$um_value = get_user_meta( $curr_user_id, 'your-key', true );
// now we check if the value is correct
if ( ! empty( $um_value ) && $um_value == 'your-value' ) {
// if so we can output something
echo 'user meta has the value';

User Selectable Delete of Pages
in my WP MultiUser project i am designing a template for deleting a page from the front-end (only the super admin can access the back-end admin panel)
I have almost achieved the desired result, but when I press "Delete," the function deletes all pages. I just want to delete only the selected page. Here is the code that I created:
<?php $pages = get_pages();
foreach ( $pages as $page ) {
$option = '<li>';
$option .= '<a href="' . wp_delete_post( $page->ID ) . '">';
$option .= $page->post_title;
$option .= '</a>';
$option .= '</li>';
echo $option; } ?>
edit 2 Sorry i miss few changes
<?php $pages = get_pages();foreach ( $pages as $page ) {
$option = '<li>';
$option .= $page->post_title;
// $option .= '<a href="' . wp_delete_post( $page->ID ) . '">';
$option .= 'Delete</a>';
$option .= '</li>';
echo $option; } ?> | You are deleting all pages with that code because you are triggering the function wp_delete_post().
You should build the url to delete the page(or post) like this:
$delLink = wp_nonce_url( get_bloginfo('wpurl') . "/wp-admin/post.php?action=delete&post=" . $page->ID, 'delete-post_' . $page->ID);
So your code should be:
$pages = get_pages();
foreach ( $pages as $page ) {
$delLink = wp_nonce_url( get_bloginfo('wpurl') . "/wp-admin/post.php?action=delete&post=" . $page->ID, 'delete-post_' . $page->ID);
$option = '<li>';
$option .= '<a href="' . $delLink . '">';
$option .= $page->post_title;
$option .= '</a>';
$option .= '</li>';
echo $option;
}

Questions on WordPress Codex Concept
When I was reading the WordPress Codex about outputting the Post and Pages I saw these two Titles at Here
> Output a list of all **registered** post types
and
> Output a list of all **public** custom post types
now can you please let me know
1 - What are Registered posts? Is there any un-registered one?
2 - What are the Public Custom Post Types? is there any Private one?
Thanks | Adding here.
`register_post_type` function have a parameter `public` which controls how the type is visible to authors and readers.
If public parameter of a post type is **true** then post type will be `exclude_from_search`, `publicly_queryable`, `show_in_nav_menus`, and `show_ui`. Read more about it in register_post_type function.
Also all post types must be registered to use in WordPress. So there is not such thing as `un-registered post type` but a registered post type can have option to be public or not based on what value you supply. | stackexchange-wordpress | {

is there any standard format that support all browser and html5 video player ?? | There is no one format that works on all browsers, for example, Firefox won't play MP4 files due to FF not having the license to use the MP4 codec.

Where should I put this custom data?
My client needs to store food nutrient data in his site's database. I have food name, calories, protein, fat, carb, fiber and other data to store for many food items.
I'm a developer but new to WP. Where is the best place to store this information? A custom table, custom post, regular...
Thanks! | Supposing that each food item is treated as a post (perhaps even a custom post type), and the parameters (name/calories/etc.) are attributes of this post, you would do well to treat them as post meta fields.
Various means exist to grant end-users the ability to maintain custom fields; my preferred option is Developer's Custom Fields, but other solutions exist. Regardless of the method used, the assumption is that for a given post certain meta fields have been populated and must be queried at runtime.
Within a loop (in particular, after invoking `the_post()`), and for a particular custom field (for illustration I will use "calories"), you would retrieve the value using `get_post_meta()` as shown below:
echo "Calories: " . get_post_meta(get_the_ID(), "calories", true);
Some assumptions are made here (that you're in a page/post loop, the data you are requesting has already been entered, and the name of your custom field is "calories"). | stackexchange-wordpress | {

Custom Fields Question
I'm new to wordpress and I am trying to understand these custom fields. I read the wordpress codex page refering to custom fields but I have some questions. I take for example my site. I created a custom field named "country_flag". I want this custom field to store for every post a link to a icon displaying a country flag.
This icon i want to place on my site after the post title to show guest in which language the post is.
On the codex page it tells me to place `<?php the_meta(); ?>` in my template. But if i have more custom fields and I want only one to be shown in my template where i put the `<?php the_meta(); ?>`, what code should I place? | If you want to display a single custom field (post meta) then you can use:
get_post_meta();
It has three arguments.
1. The ID of the post
2. The name of the post meta field (country_flag)
3. Whether or not the value returned is a single string (in your case it will be);
So the usage might be something like this:
$country_flag = get_post_meta( $post->ID, 'country', true ); | stackexchange-wordpress | {

Escape HTML on WP input

$instance['content'] = ( ! empty( $new_instance['content'] ) ) ? esc_html( $new_instance['content'] ) : '';
This works partially as it let me saves the HTML (an iframe) but displays it as code in the frontend, I need it to convert the iframe code to a working video.
I have also tried:
$instance['content'] = ( ! empty( $new_instance['content'] ) ) ? strip_tags( $new_instance['content'] ) : '';
but it won't let me save the iframe content (it clears the box).
Which function do I need to use so my widget behaves the same as the default text widget. | The default text widget - `WP_Widget_Text` \- can be found in `wp-includes/default-widgets.php`. The input is handled like this:
* `stripslashes( wp_filter_post_kses( addslashes( $text ) ) );` for the text;
I assume this should work likewise for your custom widget. Additionally there is:
* `wpautop( $text )` on the output, if the filter is set to do that;
But optimally you're taking a look at the source yourself.
Additionally the codex articles:
* Validating Sanitizing and Escaping User Data; and
* Data Validation

How to get better performance for redirect from domain.tld/35 to domain.tld/full-permalink?

{
wp_redirect( get_permalink( absint( $wp->request ) ), 301 );
exit();
}
});
While testing it seems that this approach is not the best for the performance. I wonder if there´s a better solution for this matter? | I fear the answer here is that redirecting will just never come with good performance. Especially doing it via PHP, because then it's handled rather late.
You could think about doing it via apache in particular the `.htaccess` file, which intercepts way earlier, before PHP/WordPress even come into play. Which will be better, but of course it still will be a redirect. But as @birgire pointed out in his comment, you need the concrete/exact rules, so this isn't very practical.

Function to get the name in database table from the comma separated string

Which delete query is better with prepare or delete
Just wondering which of the two delete queries would be the preffered method
$qdel = $wpdb->query($wpdb->prepare("DELETE FROM $shopping_meta_table WHERE meta_shopping_key = '%s' AND wp_user_id = %d", 'product-2', $id));
or
$qdel = $wpdb->delete($shopping_meta_table,array('meta_shopping_key' => 'product-2', 'wp_user_id'=>$id)); | By your **reputation** , It seems that you know about the wordpress very well.
Use of `prepare` method in query is to make sure we're not dealing with an illegal operation or any illegal characters.So I recommend you to delete with the `prepare` method.
Other than that, you might be aware of **SQL INJECTION**. Before release of **wordpress 2.5** , there was `$wpdb->escape()` to prevent SQL Injection whose work was to prevent SQL injection attacks and keeping the bad dudes out. Since WordPress 2.5 a new $wpdb function has been included called ‘prepare’, whose work is to prevent SQL escapes.
So All data in SQL queries must be SQL-escaped before the SQL query is executed to prevent against SQL injection attacks. The `prepare` method performs this functionality for WordPress, which supports both a sprintf()-like and vsprintf()-like syntax.
Read more about **SQL escaping**.

How to share posts in Wordpress Multisite?

Get access to Wordpress when logged out
I have a WP site with bbPress installed and bbPress Like Button (a like button plugin).

'bbPress Like Button needs bbPress installed and activated in order to work.'
This is on QA server and so I can't get access to the files.
Is there any way to fix this - Is there any way to access the dashboard to re-activate the plugin | So the plugin mishaps are blocking you from signing into the dash? You will likely need server access or someone who has this access if you're not using version control.
You can just rename the folder for the plugin that you want to de-activate (BBPress Like Button). That will force it to de-activate since the WordPress will lose track of it. Then log into the dashboard, activate the appropriate plugin (BBPress) and then return the plugin folder (BBPress Like Button) back to what it was before you changed it. Then you can activate BBPress Like Button once you're sure it has what it needs and won't break your admin access.

404 on child page when parent page slug is identical to custom post type
The internet is swamped with this issue but all the results were from 2010-2011 so I wanted to check if there was any advancement in the matter.
I have the following scenario:
* Created a custom post type "videos"
* Created a parent page "Videos"
* Created a child page "New Video"
* Changed permalinks to `%category%/%postname%`
WP automatically created the permalink for the child page as `www.example.com/videos/new-video` but the page leads to a `404 Not Found` error.
* Re-saving permalink settings does not solve the problem

* Changing the custom post type to "video" **solves** the problem

I think emoji are killing my WordPress site… How can I debug?
I have had a rather frustrating last couple of days… after quite a bit of trial and error, I have come to the suspicion that emoji are killing my WordPress installation. Specifically, emoji in the settings of my theme.
!Screenshot
In retrospect, I can see that even trying to use emoji was a bit of a risky proposition. As I understand it, they are not officially a part of the UTF-8 character set.
For the time being, I have tried to carefully go back through all of my theme settings and eliminate any use of emoji anywhere. But now, I would like to find out exactly how they are breaking WordPress and where. Trouble is, I'm not familiar with PHP beyond the basics I've needed to pick up for theme customization.
Where should I begin to debug this problem? | This is a limitation of MySQL’s UTF-8 implementation: it supports just a limited set of valid UTF-8 characters. You can convert your database to `utf8mb4`, and emojis will work. But there may be other side effects.

How can I reduce file upload size?
The current file upload size limit is 128MB. I want to reduce this to 1MB. I do not have access to php.ini file. I do have access to .htaccess and I could use this solution.
But why isn't there a method for doing this in the `functions.php` file?
** UPDATE **
So this, over at Stackoverflow, basically says why:
> Those settings are not going to have any effect when set via ini_set
>
> The reason is that PHP needs those values before your script is even executed. When an upload occurs, the target script is executed when the upload is complete, so PHP needs to know the maximum sizes beforehand.
>
> Set them in php.ini, your virtual host config, or in a .htaccess file. A typical .htaccess file would look like this
>
> `php_value post_max_size 30M`
> `php_value upload_max_filesize 30M`
So the question remains; Is there a way to set max upload size in WP `functions.php`? | Absolutely, you can simply hook into `upload_size_limit` and set a maximum filesize:
// Change the upload size to 1MB
add_filter( 'upload_size_limit', 'wpse_163236_change_upload_size' );

Relative time - how to calculate difference beween post publish date and current time
I want to calculate the difference between post's publishing time and current time, and I want to read that value as a number (number of hours, minutes, seconds whatever, i just want it to be a number).
The reason is I want to do something depending on the post's age.

$date = get_post_time('G', true, $post);

...
}
// if post is between one and two hours old
else if (($postsage >= 7200) && ($postsage <=14400)){
...
}
else {
...
}
Is this code bit valid? | To print relative time on posts automatically we can use `get_the_date` filter. We will check the time difference and print it in human readable form.
// Relative date & time
function wp_relative_date() {
return human_time_diff( get_the_time('U'), current_time( 'timestamp' ) ) . ' ago';
}
add_filter( 'get_the_date', 'wp_relative_date' ); // for posts
add_filter( 'get_comment_date', 'wp_relative_date' ); // for comments
And in your theme use `<?php echo get_the_date(); ?>` to print relative time.
If you do not need relative time for comments then remove following from code.
add_filter( 'get_comment_date', 'wp_relative_date' ); // for comments
**EDIT**
To get time difference in seconds. Use this.
$seconds = current_time( 'timestamp' ) - get_the_time('U');
