Unexpected Output: register_activation_hook with namespace
I encounter a weird error while using the `register_activation_hook` and `namespace`.
> The plugin generated 236 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
I get this error even with this simple plugin:
<?php
/**
* Plugin Name: Sample Plugin
*
*/
namespace Sample;
register_activation_hook( __FILE__, 'sp_activate' );
function sp_activate() {
}
If I remove the `namespace` the error does not occur. Do I miss something? What is wrong here? | When we are outside the `Sample` namespace, we should call the function by `\Sample\sp_activate()`, so please try the following:
<?php
/**
* Plugin Name: Sample Plugin
* Version: 0.0.2
*/
namespace Sample;
\register_activation_hook( __FILE__, '\Sample\sp_activate' );
function sp_activate() {
}
If something is printed out during the plugin activation it will result in unexpected output message. If you use for example `echo 'Hello';` in your activation function, it will generate such a message of 5 characters.
You should consider using `WP_DEBUG_LOG` and log the errors into a file, to see what kind of errors you're getting there.

404 Admin Error
I am new to WordPress and was looking at settings in the admin. I believe I changed the directory of the site from `example.com/wp/` to `example.com`. When I saved the changes I immediately saw a 404 error that says:
Not Found
The requested URL /index.php was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
In trying to fix what I messed up I came across this question which an answer said to `Delete .htaccess` however I believe the root cause in that question is different than my problem. | I found the solution.
I had to open up `phpMyAdmin` open up the database then open up `wp_options`. From there I had to change the `siteurl` and add `/wp` to the end and it works again. | stackexchange-wordpress | {

How to extract translatable (double underscores and _e) strings?
I made a custom theme and wonder how could I extract all translatable strings to a .po file so I can translate it. Do I need WPML plugin?
Ex: I have a string "soccer" which is written as `_e('soccer','mytheme');` and I want to translate it to "futebol" but how can I transport it to a .po file? | One way is to use the WordPress i18n tools. I had to checkout WordPress trunk to make it work. On the command line:
svn co
once you have trunk somewhere, you'll then want to call the `makepot` script. Again, on the command line:
php /path/to/wordpress/trunk/tools/i18n/makepot.php wp-theme /path/to/your/theme/
After that script has run, the pot files will be in whatever directory was specified in the above `/path/to/your/theme`

Add Incrementing ID to each paragraph in the_content

function ( $matches )
{
static $i = 0;
return sprintf( '<p data-section-id="%d">', $i++ );
},
$content
);
}

Is it possible to get feature image url (full-size) from an image url of smaller size?

or
Just easily remove the prefix "-150x150" ? (I'm not sure if this is proper since i need best practice also.) | The URL for rezied images in WordPress is constructed in a way that's impossible to direct reverse. Therefore, it's impossible to get the attachment associated with a URL of a resized image with 100% certainty, unless you loop through all attachments and check whether their URL matches the given URL. However, this approach is very slow and resource-intensive.

How to show file type of featured image?
How to show file type of featured image in post on single.php?
For example: Featured image type is: ".jpg"

$type = '.'.$mime_type['1'];
echo $type;

So is there any way to know is this archive page 'product' or 'blog' is active | First of all, `is_archive()` does not accept any parameters if you have read the codex, that is why it will always return true no matter what you tried on any archive page
As pointed out `is_post_type_archive( $post_types )` is the proper conditional tag to use to check for a specific post type archive page.
One thing though, your question is unclear on how you would like to use this condition, as you already have an archive page specially made for each custom post type, so to check if your on a specific archive page would not make sense. `is_post_type_archive('blog')` will always return true on archive-blog.php while `is_post_type_archive('product')` will always return false, and `is_post_type_archive('product')` will always return true on archive-product.php while `is_post_type_archive('blog')` will always return false. | stackexchange-wordpress | {

save_post action hook for comments
Is there a action similar to save_post for comments? Already tried comment_post which does not fire when clicking the update button on a comment in WordPress. | You can try the `edit_comment` hook that's fired within the `wp_update_comment()` function, called by the `edit_comment()` function when you edit a comment in the backend.
This hook is fired after the comment is updated in the database.
**Example:**
add_action( 'edit_comment',
function( $comment_ID )
{
// ... your code here ...
}
);
Notice the following comment in the source:
> The hook also fires immediately before comment status transition hooks are fired.
I find this comment somewhat confusing, because it's actually the `get_comment` filter that's fired immediately before the comment status transition hooks are fired within the `wp_transition_comment_status()` function. But it's true if _hook = action_ , but I usually understand the meaning of the word _hooks_ to be both _actions_ and _filters_. But this was just a minor detour.

I don't want to create another welcome email function.
Thanks.
**Answer**
do_action('woocommerce_created_customer', $user_id, $new_customer_data, false); | There is no actions/filters to hook to. You need to override standard `WC_Email_Customer_New_Account` class and implement your own logic. To do it you need to create your own class which will inherit that class and register it.
class WPSE8170_Email_Customer_New_Account extends WC_Email_Customer_New_Account {
function trigger( $user_id, $user_pass = '', $password_generated = false ) {
// do what you need here and then call parent method
parent::trigger( $user_id, $user_pass, $password_generated );
}
}
Now you need to register this class:
add_filter( 'woocommerce_email_classes', 'wpse8170_update_email_classes' );
function wpse8170_update_email_classes( $emails ) {
$emails['WC_Email_Customer_New_Account'] = new WPSE8170_Email_Customer_New_Account();

Custom CSS for a particular text/html widget in Wordpress
I have a couple of text widgets on my Home Sidebar. There is one text widget in particular that I want it to implement custom CSS written in my child theme rather than the default styling provided by the theme. Is that possible? If yes, how?
Edit: the below answer generally doesn't work because most widgets have their css implemented after both, the theme style and the custom style file. | From firebug, you can see the ID name of the text widget, which is "text-some number" and this is what we need to customize. the specific WordPress widget has the class name "widget" (from class="widget widget_text".).

#sidebar .widget #text-3564277 {
background-color: #fff;
border: 1px solid #ddd;
padding: 10px;
}

Get list of scripts / styles and show file which enqueued them
I want to show what scripts and styles have loaded on a page and which plugin / theme / file has added them to the page.
We can show all scripts and styles using:
<?php
global $wp_scripts, $wp_styles;
var_dump( $wp_scripts );
var_dump( $wp_styles );
?>
Or more elegantly using this answer: How do I get the $handle for all enqueued scripts?
I now want to be able to see where they were enqueued. For example if I had a JS file called foobar.js and it was enqueued by plugins/organge/orange.php I would want to output this file location along with the script.
This is for development to help isolate what is loading what. | This is not possible the way you think. It _would maybe_ be possible if you use Reflections or `debug_backtrace()`, but there's no reliable way to do this. WordPress does not keep a stack or queue where it tracks file names.
The _only_ thing I could imagine is just hooking into the action and inside `wp_enqueue_scripts()`:
wp_enqueue_scripts
and attach a tracking mechanism of _attached callbacks_ there. Note the `s` and that this is not the function that you use to attach scripts to the stack.
<?php
/** Plugin Name: (WPSE #152658) Script Loader Callback Inspector */
add_action( 'wp_enqueue_scripts', function()
{
var_dump( $GLOBALS['wp_filter'][ current_filter() ] );
}, PHP_INT_MAX -1 );
This would leave you with a queue of all attached callbacks. You can then trace them back with your IDE. | stackexchange-wordpress | {

Tell WP to use a specific template file in posts
I've searched everywhere and tried a couple plugins with no success. I'm using WP 3.9.1.

So, instead of creating different custom post types, a thing that creates other problems down the line to take care of, I just want to be able to say to wp "hey, use this template file".
How can I be able to do that? I guess it's about making wp asking the editor "for this post, what template you want to use?" in admin. | Use below code for getting post format, simple made condition if post format ="standard" then load your preferred template

How do i know the current post type when on post.php in admin?
Im trying to do something with an admin_init hook if - and only if - the user is editing a post (post.php) with post type "event". My problem is that, even though wordpress points to a global variable calls $post_type. if i do:

How to customize taxonomy archive template files for subterms?
I have a taxonomy called "location" where I have the term "Asia" and the sub-term "Thailand".
Now I created the taxonomy archive template file according to the Wordpress Codex, which is working in the following format:
* taxonomy-$taxonomy-$term.php --> taxonomy-location-Asia.php
Is there a possibility to create a template file also for the subterm, as following:
* taxonomy-$taxonomy-$term-$subterm.php --> taxonomy-location-Asia-Thailand.php | Strictly speaking, according to the **Template Hierarchy**, you cannot. Unfortunately
> taxonomy-$taxonomy-$term-$subterm.php
is not provided for in default, so this file structure will not work. The best you can do here is
> taxonomy-$taxonomy-$term.php
So for Thailand you will name your template as follows
taxonomy-location-Thailand.php
**EDIT**
Just to add to my answer, the file structure that you are looking for, it is doable outside the template hierarchy. You will just need to use the `template_include` filter hook to "redirect" Wordpress to use that specific template
function wpse_template_include( $original_template ) {
if ( has_term( 'Thailand', 'location' ) ) {
return get_template_directory() . '/ taxonomy-location-Asia-Thailand.php';

how to get the right path to images folder then display the images ?
Thanks | From your post what i understood is u need to show images saved in your plugin folder.if yes then you can go with plugin_url to link images in a plugin directoy without specifying the plugin folder name. Example:
<?php
echo '<img src="' . plugins_url('/images/header-background.png', __FILE__) . '" > ';
?>
The ouput will be like
<img src="
If you are using the plugins_url() function in a file that is nested inside a subdirectory of your plugin directory, you should use like this:
<?php
echo '<img src="' . plugins_url( 'images/header-background.png' , dirname(__FILE__) ) . '" > ';

I tried something like "selected = selected" but does not mark Argentina scored Zimbábue (rsrs) | should be `selected="selected"` NOT "selected=selected"
EDIT:
Ok I see - it's because you are using a foreach arguement to say that it's selected. Meaning that it prints the HTML showing that everything should be selected.
Try something like this:
<select name="pais" class="pais-select">
<option value="" disabled selected>País</option>
<option value="Argentina">Argentina</option>
<?php
$pais = diretorio_request('pais');
foreach(diretorio_countries() as $country) {
?>
<option value="<?php echo $country; ?>"><?php echo $country; ?></option>
<?php
}
?>

or I suppose you could do something like
<option value="<?php echo $country; ?>" <?php if ($country == Argentina) { echo 'selected="selected" ' } ?>"><?php echo $country; ?></option>

Using update_option() and get_option() is echoing escaped strings
I'm using the Option API for my theme settings page. I use the $_POST data to update the options when the changes are saved. My issue is that the strings I send get escaped and when I use this code:
<?php echo get_option('myOption'); ?>
it echoes the escaped string.
So for example, say 'myOption' = Bob's Diner
Using the above statement, it echoes Bob\'s Diner, which is definitely not what I want.
How exactly do I go about removing that backslash when I call the option on the site? | You can use PHP's `stripslashes()` command:

How to display user's nickname by default instead of username
I need to display the user's nickname by default after they are created in the DB, NOT the username.
I am creating a user with:
wp_create_user( $user_name, $random_password, $user_email );
updating the user nickname field directly after user creation:
update_user_meta($user_id, 'nickname', $user_nickName);
Now i need the "Display name publicly as" to be set to the nickname as default not the username.
My WP is automatically defaulting the users display name as the username. How do i put the selected value for the display name(Display name publicly as) as my nickname value programmatically? | Instead of `wp_create_user`, use `wp_insert_user`. So you will be able to set extra variables like `nickname`, `display_name` separately than the default value.
For your case, you can code like this:
$args = array (
'user_login' => $user_name,
'user_pass' => $random_password, //send as plain text password string
'user_email' => $user_email,
'nickname' => $user_nickName,
'display_name' => $user_nickName

Retrive images from the_content()

Thank you | There are essentially three criteria here:
* do images belong to the site (are WP attachments)
* are images attached to this post
* are images used in this post
This has side effects, like:
* images used in post are not necessarily attachments
* post's attachments aren't necessarily used in _that_ post
So the only reliable way to produce complete set of images, actually used in specific post's content is indeed to parse the content (after shortcodes like galleries and embeds) for them.
After that you can [try] reverse engineer URLs into WP's attachments, see Turn a URL into an Attachment / Post ID for example. | stackexchange-wordpress | {

Can we create a custom post template for a specific page template
I am working in wordpress for the first time and the client had a requirement that we create a template which will be used for multiple products as shown below

1. The hero image
2. The text in the hero image
3. The CTA
4. The infographic(s)
5. The alternating contents
Once these custom posts are set up, can all these posts be combined together to create one template in the backend which can be reused.
I apologize for the naiveness of the question but I come from a background where I have worked in CMS's before where you can create a template in the frontend and also create backend templates which map to the content in the front end. | Yeap,
You can work with a page or single-cpt template with custom fields. In both case, you can use a plugin like ACF to set your fields.

Create a custom attachment thumbnail for quick page load
I've been trying to find a way to create a custom image attachment thumbnail. I want to display an image attachment thumb and link to the full size. (FYI The thumb is to get quick page loading speed instead of a full size that would slow down things.)

1. create an Image Attachment Thumbnail
2. keep it Small Size

* to manually create a thumbnail for the attachment and upload it.
* use the thumbnail setting for featured-image and change that to meet my needs, but i'm using it for the featured-image.

There are multiple approaches here, but all will take some tinkering:
* you can adjust category term archives to include your CPT (via `pre_get_posts` hook)
* you can extend custom post type archives with endpoint to filter them by category
* probably more ways, it gets pretty arbitrary outside of native functionality

2. get video: take just video link and show YouTube video under the text

$new_content = wp_strip_all_tags( $content );
Then you will want to trim that to 200 characters using `substr`:
$new_content = substr( $new_content, 0, 200 );
To retrieve the YouTube video, you'll need to use `preg_match`:
preg_match( '/(<iframe.*?src="(.*?youtube.*?)".*?<\/iframe>)/', $html, $matches );
if ( $matches ) {
$iframe = $matches[1];

How to fork a plugin to avoid updates after modifications?
I have made some modifications on a plugin. While everything is now working as I like to have it, I am annoyed by the update notification.
How can I fork the plugin such, that it I'd not linked anymore to the repository, but still uses all the settings from the database? Is it as easy as renaming only the folder and the php file, or there more required?
Thanks.
P.S.: license is GPL, so I think it is ok to do it... | I believe renaming the plugin file/folder should be enough; if not, you can also edit the plugin info in the header of the plugin file and set the version to something unreasonably high. On the rare occasion I've needed to do this, I usually also update the plugin info to indicate that the plugin has been modified from the original (and why, if it can be quickly summarized).
The function that performs the update check against the WP.org API is `wp_update_plugins`. It doesn't appear to have any filters available to remove a plugin from being sent to the API server, but it is storing the results in a transient called `update_plugins` so I imagine you could hook into the `pre_set_site_transient_{$transient_name}` filter to remove your plugin from the list, which should eliminate the admin notification. | stackexchange-wordpress | {

How to set twenty fourteen header image at 100% width?
if
function wpse_custom_header_setup() {
add_theme_support( 'custom-header', apply_filters( 'wpse_header_args', array(
'width' => 1460,
'height' => 220,
) ) );
}
add_action( 'after_setup_theme', 'wpse_custom_header_setup' );
can help define the width of the header in px, how I can set up a header image at 100% to get something similar like < | The header image is already set to 100% width by default. Check lines 571-578 in style.css of the twenty fourteen theme
#site-header img {
max-width: 100%;
}
If you need a bigger header, you'll need to set the sizes accordingly in the code in your question, which I suppose you got from one of my previous answers :-)
Just another note here, you can play around with the max width of `site-header` found in lines 847 to 853.
.site-header {
background-color: #000;
max-width: 1260px;
position: relative;
width: 100%;
z-index: 4;
}
You need to set `max-width: 1260px;` to your set width in your function | stackexchange-wordpress | {

Security around save_post hook
There are a lot of examples using the `save_post` hook, that include adding and verifying a nonce, and checking the user has appropriate permissions before you continue.
Is this necessary?
When updating/publishing a post, WP verifies the normal nonce, and checks permissions itself, redirecting to a 403 or 'Are you sure you want to do this?` page if something doesn't check out. As such, the hook won't even be called if a bad request was made, so why would I have to double check these things myself? | The `save_post` hook is called every time someone calls the function `wp_insert_post()`. Plugins do that, unfortunately some themes too, and WordPress itself on several places when …
* someone uses _post per email_ or XML RPC
* an auto-draft is created
* the _Quick Draft_ feature on the dashboard is used
* a navigation menu item is added
* a revision is created
You really don’t want to handle all those action without your own verification.
Besides that, nonces _should_ guarantee that an action cannot be repeated by someone who listens to another person’s network traffic. In theory, nonces prevent that. The default WordPress nonces are not very secure in that regard, because they can be reused. But your users might have installed a plugin that creates real nonces. Do you really want to bypass their extra security measures? Probably not. | stackexchange-wordpress | {

Echo page path suffix only - not the title, path or permalink
Is it possible to echo a page path suffix only? ie: if the path/permalink is example.com/about, echo just "about"?
My page paths are different than my page titles (ie: page title for example.com/about is "About ACME Co.") so I cannot use `the_title()`
I am trying to echo just the suffix so it is the same name as an icon image for each page, so if the page is "about", the icon is `icon_page-about.png`, like this (wpse_page_suffix is where I need the help):
`<img src="<?php bloginfo('template_directory'); ?>/_img/icon_page-<?php wpse_page_suffix();?>.png" alt="Icon - <?php the_title();?>" />` | Use the Post Object instead.
When in the loop, do this:
global $post;
echo $post->post_name;
That should do the trick. | stackexchange-wordpress | {

How to use custom stylesheet only for a template in child theme
I am using Themco's X theme. To modify the theme styles I used the Ethos child theme provided by Themeco. I have designed a custom template in the child theme. Now I want a stylesheet custom-style.css to be used only for that theme. But when I use this
<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/custom-style.css">
the link that comes up is that of the parent theme rather than the child theme. What else can be done to use that stylesheet only for that template?
Please note I don't want that stylesheet to be used in any other template. | Try this:
add_action( 'wp_enqueue_scripts', 'my_custom_styles_function', 100 );
function my_custom_styles_function(){
if (is_page_template('test-template.php')) {
wp_enqueue_style( 'my-custom-css', get_stylesheet_directory_uri() . '/custom-style.css' );
}
}
`wp_enqueue_scripts` hook is used for including new stylesheet. Here template is `test-template.php`. Change it with your template. Stylesheet will only be included in your page template. | stackexchange-wordpress | {

Hook into 'when user logs in' [persistent login]

Making a string translation ready with html in it
I can make a simple translation string like this:
<?php _e('Hello world','text-domain'); ?>
But how to make a translation string if there is a markup in it? For example this:
<?php _e('<span>Hello</span> world','text-domain'); ?>
Is the above correct? | Localizing a string with html markup inside the string can be a very opinionated story as you can see from one of my questions when I started out.
I would not say you are right, neither would I say that you are wrong, but I would say that your method is not prefered.
If you have a look at **I18n for WordPress Developers**, you'll see that you should use `printf()` and placeholders when you have variables inside a string, well, the same applies for markup. My emphasis, you should never translate html tags, always use html tags outside of your string.
An example, with what I've just covered, should render a string like this
printf(__( '%s Hello %s world', 'textdomain' ), '<span>', '</span>' ); | stackexchange-wordpress | {

How do I get content of custom post type through post ID in wordpress
My custom post type name is movie_reviews. Inside movie reviews there are multiple post but i need only that post whose id is 244. My code for it is
<?php
$my_query = new WP_Query('post_type=movie_reviews&ID=244');
while ($my_query->have_posts()) : $my_query->the_post();
the_content();
endwhile ?> | Have a look at the Post & Page Parameters Section in the `WP_Query` Documentation
For getting a Post by Post ID, you need to use this:
$my_query = new WP_Query('post_type=movie_reviews&p=244');
If you only need the content of one specific post, you can also do this:
$mypost = get_post(244);
echo apply_filters('the_content',$mypost->post_content);
In this case, you don't need to worry about the loop or the global vars getting overwritten, removing your main loop. | stackexchange-wordpress | {

Custom Maintenance Page
I'd like to create a custom Maintenance Page for my needs, but not only when wordpress is updating. I just want to close my site for a period with all the necessarily status code sent. What is the best way to do it? | For such maintenance mode, I found the following plugin a better one (with currently rated a 4.1 on 5):
> **Easy Maintenance Mode** -- WordPress Plugins
It's a good one, and the screenshots are there to describe its look and functionality. It'll create a maintenance banner foo all other users except the Admin. It's has a good user connectivity with the social networking links below, so the user who are seeing the Maintenance notice, won't go away - they will be in touch with your social updates.
And there are many facilities described in the plugin page.
BTW, if you find difficulties functioning any plugin like this, try switching to the default theme (Generally TwentyFourteen), and try deactivating all other plugins and activate them one by one to find which one is conflicting.

Would it be dangerous to send all the wp_options to javascript file?
I've noticed that wordpress allows me to send the wordpress options to javascript via wp_localize_script:
wp_localize_script( $this->plugin_slug . '-plugin-script', 'wp_options', wp_load_alloptions() );
This way, my javascript can access different settings such as what day the week start on and what date format the user has chosen.
Are there any risks, sending all the options as a variable to js, or is this okay? I've noticed that options such as "logged_in_key" and "logged_in_salt" becomes available in the front end too.
My gut tells me that this is bad practice - securitywise ? But I wanted to hear from someone who knows more about security in wordpress.
Thanks.

How to extend parent theme sections and settings to Options Tree
I am developing a child theme based on a theme that use Option Tree for it's options.
Is it possible to add a new section with my child theme settings to the already defined sections by parent theme ?
The only reference I found was < but I couldn't implemented. I also read a lot the Option Tree code but couldn't find the appropriate filter. | For anyone who want to achieve the same thing :
add_filter( ot_settings_id() . '_args', 'my_ot_setting');
function my_ot_setting($custom_settings){
//do some work with the settings and the sections, ie append your settings.
return $custom_settings;
}

Changing admin Textarea to integrated WP editor
I'm currently working on a theme for my page that utilizes wordpress's built-in gallery system to make a slideshow with php/jquery.

<
The caption is what you see as the title, and in the gallery "description" TEXTAREA is where you see all the dummy text.
**Now, My Question:**
How would I go about changing the built-in description textarea (see image), (in the gallery back-end) to the built-in wordpress editor (tinyMCE)? Our writers here aren't the best with HTML, and want to make it as easy as possible for them.

Get category id for a custom category and display it in a class

$category = get_the_category();

Sticky posts are not showing at the top of category posts
Can anyone tell me why sticky posts are not being displayed at the top of the following query:
$wp_query = new WP_Query(array(
'post_type' => 'post',
'posts_per_page'=>10,
'category__in'=>array( 5,140,430 )
));
It was working fine until I added the `'category__in'=>array( 5,140,430 )` parameter, but the stick posts are in category 430 so I don't see why they would suddenly stop appearing at the top?
Edit: This appears to be a long-standing wordpress issue between `category__in` and sticky posts. Wordpress codex says stickies should always appear on the front page, but seeing as how this is on the front page and doesn't work it must be a bug. | I don't have direct experience with this, but from what I read...
Sticky posts don't show up by default on category pages, so adding the categories may throw the query into an "I don't care about sticky posts" mode.
You could try running a query first that just grabs the sticky posts, using arguments like this:
$sticky = get_option( 'sticky_posts' );
$args = array(
'post__in' => $sticky,
'ignore_sticky_posts' => 1
);
You may be able to include `category__in` there as well, to get only sticky posts from the categories you want. Again, I haven't tried it, but it's a good avenue of approach.
