How to remove WPML Generator Meta Tag by theme's functions.php (override plugin function)?
I've tried hard to find a way to not let plugin WPML output the following `<meta name="generator" content="WPML ver:2.8.1 stt:3,1;0" />` tag in `<head>` via help of theme's `function.php`:
It's called in `sitepress.class.php` beginning with line 255
if ( !is_admin() ) {
add_action( 'wp_head', array( $this, 'meta_generator_tag' ) );
}
This specific question has already been asked once in WPML forum. I've tried:
/* ::: Disable WPML Meta Generator Tag ::: */
if ( ! is_admin() ) {
remove_action( 'wp_head', 'meta_generator_tag', 20 );
}
add_filter( 'meta_generator_tag', 'theme_generator_tag' );
function theme_generator_tag() {
return false;
}
\-- without success | The instance of this class is made global by WPML, so this should work:
if ( ! empty ( $GLOBALS['sitepress'] ) ) {
add_action( 'wp_head', function()
{
remove_action(
current_filter(),
array ( $GLOBALS['sitepress'], 'meta_generator_tag' )
);

Toolbar/topbar missing on homepage only?
My theme seems to have the `<?php wp_footer() ?>` and `<?php wp_head() ?>`, yet it's still not showing on the homepage of my site.
However, it is visible on all other pages and posts. | As Mayeenul wrote: Use Firebug/Chrome Inspector to see what's wrong.

add_filter('show_admin_bar', '__return_false');

How to get particular data from wp_list_comments outside the loop?

Can wp_list_comments output into variable?
Is there any way how to output `wp_list_comments()` into a variable?
Something like `$output = wp_list_comments(array('reverse_top_level' => false ), $comments);`
I am writing a plugin and it would be handy to use standard WordPress function instead of writing my own. | In the default usage this is impossible due to the nature of the default comment walker which always directly outputs. But the function allows to provide a custom walker.

Connect to remote database using Localhost install
I will be designing and developing a website for a client but want to allow the client to add content while I am working on the design and development of the site so that it is pretty mich done by the time I am finished.
Currently, I use XAMPP on port 81 so my project URL looks something like
My wp-config file has all the settings I need to the remote DB and yet, when I run the
URL it constantly redirects me to
I've removed all htaccess files thinking the problem was there but that didn't work. My ISP suggested opening port 3306 which I have done but that's not done the trick either.
I don't know if it has to do with port 81 on Xampp perhaps?
**EDIT:** General settings link through to the online version of the site so
Site Address = <
WP Address = <
Many thanks | I think s_ha_dum is in the right track, but I think he got it backwards.
You want to:
1. develop/design locally
2. connect to the REMOTE database and work with his content?
You need a remote (staging) installation of WordPress, where the client can create/enter his content.
You need your local WordPress site (localhost) to point to the remote database, to grab the content he is using.
So, you would have your < set up for the client to edit - just even with a vanilla WP install. This site would be connected to it's own database.
Your localhost site would have the REMOTE site's database credentials, with the `DB_HOST` set to < or whatever the mySQL path is if it's accessed another way through your hosting provider.
On your local site, keep the `WP_SITEURL` and `WP_HOME` set to localhost. Otherwise, you'll get redirection loops. | stackexchange-wordpress | {

Create "new pages" within the admin section of plugin
Here is my situation, I'm trying to create my first plugin for Wordpress, but I'm having an issue of trying to change the display within the plugin admin page.
Here is what I currently have:
!enter image description here
As you can see I have a couple links on the new page. What I want to do is to change what is being displayed in the window when I click on a link.
If this has been asked, I'm sorry, please point me to the post, but I'm not sure how to word what I'm trying to do. I want to be able to change the view based on links that are clicked. So if I wanted to add a customer, I could click on the 'Add Customer' link, and the display a form to add the user, all the while maintaining the admin portion (the links of the left).
I hope this makes sense. | The easiest way is to add another $_GET parameter to the URL. In the moment you are viewing `admin.php?page=Customer_Search`. You could make your links go like `admin.php?page=Customer_Search&type=your-page`.
In your plugins files you can then output the desired content based on that parameter.

Put password on a wordpress link in a article
I've trying to find out how to do this in wordpress and I've searched the web, but I can't find any easy way to make my visitor only see one link if they enter a password to be able to see it.
Is there any plugin or solution that could do that ? | I think this is almost what the article Add Private Content to Posts via Shortcode talks about. But it's only for registered users:

function private_content($atts, $content = null) {

return '<div class="private-content">' . $content . '</div>';
return '';
}
And used inside the post/page like:
> [private]
> This post contains registered-only content!
> [/private]
To add a password functionality, you'd have to add a `<form>` inside the shortcode function and show the content after the password is successfully `$_POST`ed.

Displaying posts sorting by a custom criterion
I wish to display my posts, not according to the date, but to a completely custom criterion. Ideally, I would manually set a numerical value to each post and the WP loop would display posts according to this value.
So if post X has value 1, post Y has value 2 and Z value 3, it would display first X, then Y, than Z, even though the date criterion would entail a different order. Hope it makes sense.
How to achieve this? | Save the order in a Custom Field, then modify the main query to order on that custom field via `pre_get_posts`. Example for posts page:
function wpa_custom_order( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
$query->set( 'meta_key', 'your_order_key' );

Can I safely remove banned names from WordPress?

My particular question pertains to "blog." I would like to use is as a name for a network / multisite that I am installing. | The slug blog is reserved for the main/root site of a wp multisite setup. In short, _I do **not** recommend trying to use it for something else_ \- it only produces trouble.

I could describe how to do it or link you to some how-to's, tutorials out there, but I decided against it, because it's just **not advisable** to do that. So if you really want to try it, you have to find the information yourself - here or on the net.

wpdb Cannot Access Associative Array Data in a Count Query

Notice that, one is `/?tag=` (i.e. a query) and the other `/tag/` (i.e. a subdirectory).
I deactivated all plugins but both URLs were still "200". Can't find any settings to change. Any suggestions for fixing this? | I would like to suggest you to learn how WordPress Rewrite API works. When you learn it, you won't have such kind of questions. Take a look at The Rewrite API: The Basics and The Rewrite API: Post Types & Taxonomies.
**TLDR:** The permalink structure like ` is the default approach to determine what should be displayed on a page. In the same time this ` is advanced version of default permalink structure. Internally WordPress will reformat advanced version to `index.php?tag=santas-workshop` and will use it as current request URL.
So you don't have to worry about existence of `...?tag=...` URL, it is standard and expected permalink structure for WordPress. Just use your advanced version of URLs.
Even more, your theme could support canonical URLs and will add canonical URL meta to each page. In this case Google Bot won't care which URL he will use to grab your page, it will always refer to canonical one found in meta. | stackexchange-wordpress | {

I am working with a custom taxonomy that operates like tags. I have added a custom field to that taxonomy. When the user adds a new term, the data in my custom field is not cleared.
I have tried using jQuery to clear the fields when the submit button is clicked, but of course this clears the fields even if the tag is not added (if, for instance, the name field hasn't been filled out).
Does WordPress offer any callback or hook-like system on the Javascript/jQuery side of things which I could use to execute a function when a new tag is added?
I believe I can hack a solution by searching for any fields with the class 'form-invalid' and not clearing my data. But I thought I would check first to see if there is a more stable and future-proof solution.
Thanks. | After some experimentation, I found the best hack to be:
$('#addtag #submit').click(function () {
// Look for a div WordPress produces for an invalid form element
if (!$('#addtag .form-invalid').length) {
// hide elements and reset hidden field
}
});
Binding to the click event on the submit button captures both click submissions and submissions where the user hits enter in a text field. The latter were not captured when bound to a submit event on the form element.
Checking for the .form-invalid element is not a perfect solution, as WordPress could easily change the class name in the future. But I found it the most comprehensive at catching an empty name field or a duplicate name -- neither of which WordPress will allow to go forward. | stackexchange-wordpress | {

Adding Woocommerce to my own theme, how do I do it?
After searching and trying for days, I'm starting to get agitated..
I have a custom theme for Wordpress, wich seems to function OK. But after installing Woocommerce several widget don't work, such as the shopping cart and lightbox.
I found out that it has something to do with my theme not being compatible with Woocommerce because when I change to a standard theme everything works as expected.
On Woocommerce docs I saw I might have to add some hooks to my functions.php but I can't figure out where to add these hooks...
Can anyone point me in the right direction? | Open your FTP browser and go to your WordPress root folder. Find `wp-content/themes/` folder, there should be your theme folder and `functions.php` file inside of it. Open `functions.php` file in a text editor application.

Is it possible to personalize the Media Library?
When we create a new post and click on Featured Image, I realize that WP creates a folder structure "year/month/image.jpg".

Working with l10n contexts (_x etc)
Basic l10n from a .mo file generated out of PoEdit works fine.
But as soon as I introduce `_x`, or variants, the link breaks, because as best as I can tell, PoEdit, completely ignores the context, and does not generate the corresponding `msgctxt` line in the .po/.mo files.
`_x`, `_ex` and other variants are all added to the keywords, and PoEdit **is** finding and parsing `_x()` occurrences within my source code. It's just not capturing the context and it is not generating the `msgctxt` line in the resulting .po file.
What's the workaround ( _other_ than manually editing the .po or .pot file?) | When adding _x to the keywords, try it this way:
_x:1,2c
This tells the parser to watch out for _x and to take the first argument as msgid and the second argument as a comment, which will then be recognized as context by poEdit and inserted as msgctxt.
Oddly enough, my poEdit then shows me the msgid twice in the "new/old" messages window. However, in the messagelist everysthing is correct then. | stackexchange-wordpress | {

How to put custom admin setting field into a shortcode

using wp_tag_cloud with custom taxonomy

* /events/2017-08-23/
* /events/2017-08-19/
* ... (thousands more)

How to detect that site is hosted on WPEngine?

So I need to not run the plugin on WPEngine hosting. Any thoughts? | From a quick look at wpengines headers it looks like there may be some info you can check.

Of course the problem is this can change at anytime outside your control.
### Updated:
There is another workaround to figure out whether WPEngine is used. WPEngine uses its own MU plugin, which contains `WPE_API` class. By checking whether this class exists, we can say whether the plugin is hosted on WPEngine hosting or not.

Pass boolean value in shortcode
In WordPress shortcodes, how can I pass boolean attributes?
Both of `[shortcode boolean_attribute="true"]` or `[shortcode boolean_attribute=true]` are giving string values.
EDIT
There would be no problem for users who know what they're doing if I use the trick which was commented by @brasofilo. But some users will get lost if they give an attribute `false` value and receive `true` value. So is there any other solution? | Is easy to use `0` and `1` values and then typecasting inside the function:
`[shortcode boolean_attribute='1']` or `[shortcode boolean_attribute='0']`
but if you want you can also strictly check for `'false'` and assign it to boolean, in this way you can also use:
`[shortcode boolean_attribute='false']` or `[shortcode boolean_attribute='true']`
Then:
add_shortcode( 'shortcode', 'shortcode_cb' );
function shortcode_cb( $atts ) {
extract( shortcode_atts( array(
'boolean_attribute' => 1
), $atts ) );
if ( $boolean_attribute === 'false' ) $boolean_attribute = false; // just to be sure...

wp-login.php not returning error messages / or gives 404
I have several WP sites that were logging in fine last week. Now today thay are all failing to login using the native wp-login.php.
The strange thing is some of the sites have the "Woocommerce" plugin installed, using the plugin login form I can access the dashboard. But not using wp-login.php
I have already tried:
* adding this to wp-config.php
/** wp-admin login fix */
define('ADMIN_COOKIE_PATH', '/');
* re-uploading all wp files apart from wp-content
* Changing file permissions of wp-login.php
* permalinks on and off
* removed .htaccess
* Disabled Plugins
* 100% fresh install of WP 3.6.1 on a new DB
The thing that is confusing me is that I can still login using woocommerce on sites that have it. And the native login was working last week.
Could this be a hosting issue?
Any help / suggestions would be very much appreciated.
Thanks in advance
Joe | Ok the problem has gone. As strangely as it appeared it vanished. I got a call form a client later that day I asked them if they could login, yes they could.
I then tried logging in through my phone this was also successful.
So the problem seemed to be localised to my computer.
I logged in the next day and all was fine. I still don't know what caused the error but its gone now.

Insert images into wordpress post with a query
I have a Wordpress installation with 2.000 posts. Also in a separate table of my database I have a set of image paths and the filenames of the images, each image is assigned to each post of my Wordpress installation based on the post id.

1 | img1.png
2 | secondimage.jpg
...
2014| onemoreimage.gif

foreach($your_table as $post_id => $image)
{
//full path to the image
$image_path = _YOUR_FULL_ABSOLUTE_PATH.$image;
/**
* Get an ID of the inserted attachment
* This takes care of resizing image and stuff…
* The fourth param I would sugest you to keep true, since in case of duplicate entry in your table, it will not have been inserted more than once
*/
$featured_image = wp_insert_attachment(array('attachment_meta'), $image_path, $post_id, true);
//assign featured image

What are the disadvantages of using global variable?
I am a newbie at WordPress. In my "recent posts" shortcode, I used `global $post` variable, because `the_title()` function was giving me page's title, not post's title. I am not exactly sure, but I thought that's because of loop inside of a loop.
Some advanced users here tell me not to use `global` variable, so using `global $post` variable inside my "recent posts" shortcode is good or not? | The `global` variable `$post` will be set to the first post in the main query. When any Loop runs (assuming it is constructed correctly), whether the main Loop or any number of secondary ones, `$post` will be set to each post in that/those loops in turn. At the end of the Loop, it will be set to the the last post in the last Loop that ran. The functions `wp_reset_query` and `wp_rest_postdata` help clear this up in a lot of cases.
I am pretty sure that the problem is the construction of your "loop inside of a loop" but you don't post the code so guessing is all I can do. My guess is that you have something like:
$recent = get_posts(/*...*/);
foreach ($recent as $r) {
the_title();
}
And you need:
$recent = new WP_Query(/*...*/);
if ($recent->have_posts()) {
while($recent->have_posts()) {
$recent->the_post();
the_title();
}

Tracking Disqus comments on Google Analytics

I have researched the problem, and there's some documentation for it, but it's not very clear. So far I've found some help from Disqus themselves (here), and from On Digital (here), so now I know what code to add.
What they don't mention is where to add it.
Do I insert it in one of the Disqus plugin files? My theme? Which file, and where? | You can use that snippet just anywhere where it can be rendered on single pages. For example, you can paste this under functions.php of your theme:

function disqus_config() {
this.callbacks.onNewComment = [function(comment) {

Get post object in shortcode function

$section_id = 16;
$section_home = get_post($section_id);
setup_postdata( $section_home );
the_content();

return "";

How to redirect homepage to actual URL?
I have a stupid problem. In the custom header template I include on all pages are some images. When I set the links to the images as images/image.png it works on the homepage but not on other pages.

This is because the homepage url is given as 'mysite.com' instead of 'mysite.com/home/'.
Is there any easy solution to this problem?
My guess was to redirect any visit to the homepage to 'mysite.com/home/'. But it looks like Wordpress itself prevents this. If I type 'mysite.com/home/' in an adress bar it redirects immediately to 'mysite.com'.

How do I change the value of lang=en-US
I have noticed that in the `<html>` tag on my WP site that the language is defined as US English.
<html lang="en-US" prefix="og:
I would like to change it to British English `en-GB` but I'm not sure of the best way.
I dug around and found `language_attributes()` in `general-template.php` which makes a call to `get_bloginfo('language')`. I could manually insert the value here but that doesn't seem like the best way to do it.
What is the proper way to change this value? | The value for that string is normally taken from the option `WPLANG` in your database table `$prefix_options`. You can set it in the backend under _Settings/General_ (`wp-admin/options-general.php`) or per SQL.
There several ways to change that value per PHP:
1. Create a global variable `$locale` in your `wp-config.php`:
$locale = 'en_GB';
2. Declare the constant `WPLANG` in your `wp-config.php`:
define( 'WPLANG', 'en_GB' );
This has been deprecated, but it'll still work.
3. Filter `locale`:
add_filter( 'locale', function() {
return 'en_GB';
});
This a very flexible way, because you can add more conditions to that function, for example check the current site ID in a multisite. | stackexchange-wordpress | {

Is there any simple wordpress search template that works with existing searchforms?

Is there any default wordpress search template that I can use and that will work with my existing search forms?
In regards to Toscho's questions asked here:
1. My site doesn't have that much content, so slowness is not a problem.
2. Search results may point to a specific page, the page that hosts the widget
3. I want only to display results from text widgets. | Widget content is stored in the `$wpdb->options` table as serialized data. You can search that with SQL because to SQL serialized data is just a string.
SELECT option_value FROM {$wpdb->options} WHERE meta_value LIKE "something"

* The table is not indexed for that kind of search
* Searching serialized data is dicey anyway
* And I have no idea how you are going to associate the widgets with the pages. That does no happen by default and you have not answered my question about that point.
Put together you aren't going to have a very efficient query and once you jump through hoops to associate the widgets and pages/posts it is going to be even less efficient still.

Is there a way to call on just the content of a Page without actually using that Page?
The question sounds weird i know, but what i'm trying to do is add a gravity form into a template that i made.
But all of their tutorials seem to be more along the lines of adding a form to a page and not so much to a template.

But I have no idea of how do I fetch the content of any page.

$p = preg_split( '/<!--more(.*?)?-->/', $p->post_content );
echo $p[0];

If I write like `<?php echo get_avatar("[email protected]"); ?>`, then it shows my avatar through `user-avatar` plugin.
So if I can get the author's emails, it works all fine.

I'm stuck now. How can I set user avatar in post meta area? | Use `get_the_author_meta()`, this function returns data, it doesn't display it. For example:--

Unable to access wordpress login.php

Comments from mobile apps & Disqus
I'm currently using Disqus in my WordPress Installation, and I am pretty happy with it. However, I'd like to extend my native mobile app (Windows Phone) to allow the users to post comments directly inside the app. I'm using a framework which supports WordPress comments for registered users out of the box, and I wouldn't want to rewrite the app to explicitly support Disqus. But as far as I know I can't combine both systems without problems, right? I'm certainly not the only person with that problem, so what's your strategy? Should I switch to Jetpack comments? I don't want to loose social login options, at least on the normal homepage.

arguments for comment_notification_text filter
From WP codex:
> comment_moderation_text: applied to the body of the mail message before sending email notifying the administrator of the need to moderate a new comment. Filter function arguments: mail body text, comment ID.
Nevertheless, when I put in my functions.php:
function x99($textMsg, $comId) {
if (is_null($comId)) {
return "empty";
} else {
return ($textMsg);
}
}
add_filter("comment_notification_text", "x99");
the notification message body is "empty". So comment ID is null. Why? How can I retrieve it? | For the arguments, check the source:
$notify_message = apply_filters( 'comment_notification_text', $notify_message, $comment_id );
You have two parameters. The first is the notification text itself, prior modification by your filter. It is constructed earlier in the same function and is different for comments, trackbacks, and pingbacks. The second parameter, as you might guess from the name, is the comment ID. That is all correct, as per the Codex entry you found.
However, your problem is that only the first parameter is passed by default. If you want any of the others you have to ask for them by means of the _fourth_ parameter of `add_filter`.
add_filter("comment_notification_text", "x99", 1, 2);
The third parameter is a priority. You can raise that or lower it depending on your needs. `1` should run your filter early. | stackexchange-wordpress | {

Register Taxonomy - What is `query_var`?
The Codex doesn't really explain it very well, what is it used for and how do I use it exactly? | It is explained pretty thoroughly in the Codex, in my opinion. It serves a purpose e.g. when you want to grab posts for your taxonomy, it is a URL slug for your taxonomy, e.g. `example.com/tag/cats` -> `example.com/query_var/cats`.
> Note: The query_var is used for direct queries through `WP_Query` like
new WP_Query( array( 'people' => $person_name ) )
> and URL queries like `/?people=$person_name`. Setting `query_var` to `false` will disable these methods, but you can still fetch posts with an explicit `WP_Query` taxonomy query like
WP_Query(array('taxonomy'=>'people', 'term'=>$person_name)).
Basically, `query_var` is part of the WordPress Query Vars. | stackexchange-wordpress | {

Alternative to file_get_contents() for theme operations

Disqus resetting comment count to 0
For some reason my Disqus comment system seems to resetting the comment counts to 0 on the main page. If you load my site the current blog at the top has 1 comment, you can see it says 1 very briefly then changes to 0. Refresh the page and keep an eye out for it if you miss it. I have no idea why it's doing this. If you click the blog to read it, the comment count correctly displays 1.
Also, the 3rd blog down regarding VPNs, reads 0 comments on the main page and 0 comments when you click on it, even though it has a comment.
Can anyone suggest a solution?

Cite-Tag for blockquotes
I want to have a cite underneath my blockquote, that has a certain style.
"Blockquotes are an essential part of a fancy website."
– Cite
The markup should look like this:
<blockquote><p>Blockquotes are an essential part of a fancy website."</p>
<cite>Cite</cite></blockquote>
But the WYSIWYG-Editor does not offer me the possibility to define a cite for the blockquote. And I can't force my users to write the HTML by hand.
Is there a way to make the WYSIWYG-Editor generate the required markup? | The TinyMCE Custom Styles Codex Page should get you through this.
There are code snippets on that page, but, as an overview, the process requires two steps:
1. Add the TinyMCE "styleselect" element to the first or second row of icons.
2. Add one or more elements to that styleselect menu.
If this were me, I would consider also _removing_ the blockquote button from TinyMCE and then adding `blockquote` as an option in the styleselect along with `cite`. Doing it that way means your editors can find the correct markup for an entire `blockquote` in one place.
And I hope this goes without saying, but make sure to implement a custom `editor-style.css` file so that the `blockquote` and `cite` styles match the theme output. | stackexchange-wordpress | {

Validating custom meta boxes with jQuery results in posts being saved as draft instead of published post
I have a custom post type with a bunch of custom fields. I want to validate the meta box input with jQuery as soon as you press the Publish button. Here's what I have (I left out all my validation stuff):
$("input#publish").click(function(e){
e.preventDefault();
$("#ajax-loading").show();
$('form#post').submit();
});
As you can see I am only interrupting the form submit at this point, nothing else going on. However, posts are now saved as drafts only and I can not manually set them to published (I have administrator priviliges). As soon as I remove above code, all is back to normal.
Is there any way to get this type of client side validation working properly without using plugins? I'm on Wordpress 3.6.1. | So here's what I ended up doing: I hide the publish button, replace it with my own publish button (one that does not submit the form) and when you click that button the validation script is executed. When there are no errors, a click event is registered on the original publish button. That way, no more drafts and problem solved. | stackexchange-wordpress | {

Custom Post Type Archive in Sub Folder
I have a sub-directory in my Wordpress theme (there are a lot of pages and I want a more logical structure). I have a custom post type called "entry" but if I place the archive-entry.php template in my sub-directory it is no longer picked up by the theme.
Is there a way I can put my custom post type archive templates in a sub-directory? | Unlike page templates, WordPress doesn't look in subdirectories for post template pages. The base function used for locating such templates is `locate_template()` (see source), which looks in the root directory of your theme (and parent theme).
_(On the other hand`get_page_templates()` searches sub-directory)_.
You can use `template_include` filter (which filters the absolute path to your template) to change the template used:
add_filter( 'template_include', 'wpse119820_use_different_template' );
function wpse119820_use_different_template( $template ){
if( is_post_type_archive( 'entry' ) ){
//"Entry" Post type archive. Find template in sub-dir. Look in child then parent theme
if( $_template = locate_template( 'my-sub-dir/archive-entry.php' ) ){
//Template found, - use that
$template = $_template;

How to get author's name by author's id

<?php echo $recent["post_title"]; ?> by

</ul>
But `$recent["post_author"]` returns only id of author. And this is outside `The Loop`, so I can't use `the_author()` function.
How can I get author's name from ID? Or maybe there is a better way to do it? | Try `get_user_by()`:
get_user_by( $field, $value );
In your case, you'd pass ID, and the user ID:
// Get user object
$recent_author = get_user_by( 'ID', $recent["post_author"] );
// Get user display name

How to show 5 posts from specific category on related page?

How do I reference the front page's parent Page object?

The problem is I'm trying to access the core Page to pull out some information. On any other Page I could look to `$post` but in this setup, with blog posts being present, that variable is otherwise taken.
How do I reference the underlying Page object? | You can get the ID of the front page via `get_option( 'page_on_front' )`. (See also: WordPress option reference.)
From there, you can query the page object via `get_post()`:

Multiple variables through wp_get_image_editor
I want to merge 2 images with imagick.
I already know how to merge them with imagick, but I need to pass 2 variables through `wp_get_image_editor` to get this to work.
I named the 2 variables `$background` and `$logo`. `$background` contains the background image path. `$logo` contains the logo image path.
Does anyone know how I should do this? | Mike Schroder said:
"WP_Image_Editor is built to handle one file at a time, and there isn’t anything built in to combine two images by default.
The main reason here is that the files in-memory aren’t compatible with one-another if different editors (say, GD and Imagick) are used for each.
There are a few different ways to handle it, of course, but one way to solve the problem here would be to load one of the two images, then extend the Imagick editor (or both editors, if you prefer more compatibilty) to support combining images. Say, with a $image->combine( ‘filename’ ) method.
First, you’d load one of the images with wp_get_image_editor() (and specify that ‘combine’ is a required method), then call your combine method while specifying the second image." | stackexchange-wordpress | {

Wordpress 3.6 Video shortcodes in template
