Limiting post list by taxonomy
I currently have the following code pulling the 10 latest posts from a specific category, I would like to filter those posts to a certain custom taxonomy which I've set up called article type.
What do I need to modify to incorporate this filter?
<div id="btcc" class="main-headline-box">
<h2>Features</h2>
<?php $btcc_query = new WP_Query('category_name=btcc&showposts=10'); ?><ul>
<?php while ($btcc_query->have_posts()) : $btcc_query->the_post(); ?>
<li><a href="<?php the_permalink() ?>" title="Permanent Link to:
<?php the_title_attribute(); ?>">
<?php the_title(); ?></a></li>
<?php endwhile; ?><li class="read-more"><a href="">Read more from the BTCC Archive</a></li></ul>
</div> | A simple search in codex shows how to do that :
$args = array(
'post_type' => 'post',
'tax_query' => array(
array(
'taxonomy' => 'people',
'field' => 'slug',
'terms' => 'bob'
)
)
);
$query = new WP_Query( $args );

Get query result before posts are displayed?
If I want to modify the query, I can use `pre_get_posts` filter. But what if I want to loop through the queried posts before they are ran through the `The Loop`? Is there a filter/action hook for that? I want to find out if all the queried posts belong to same `term` and then do something if they are not. Please note that creating a custom `Query` is not an option. | You can use the `the_posts` filter to loop through the results before they get returned.
Proof of concept:
function test_the_posts($a) {
var_dump($a); die;
}
add_action('the_posts','test_the_posts');
I am fairly certain (though I haven't tested it) that you could pretty easily break pagination and probably other things by fiddling with that, so be careful. | stackexchange-wordpress | {

How to rename wp-includes folder?
Is there a way that we could rename wp-includes folder
I have found out there are ways to do for other folders. But how do we do it for wp-includes folder? < | Unfortunately not at the moment. If you look in `wp-includes/default_constants.php`, the `WP_CONTENT_DIR` and other constants all have a `if ( ! defined(constant) )` check before them.
`WPINC` (the `wp-includes` constant) does not. It's defined in `wp-settings.php`, and has no `if ( ! defined(WPINC) )` check, so defining it before hand (in your `wp-config.php`) would just result in an error.
Also, altering core you could do this, but as soon as you update WordPress, Core files would be reverted, and therefore it would revert back to `wp-includes`.
I suggestion just masking your site with WordPress in a subdirectory (call it `xadw` or something nobody would guess) and just set the home URL to be the actual domain. Then put your `wp-content` folder in another folder, so it won't be obviously when people look at uploads, etc. | stackexchange-wordpress | {

automatic title through filter
the template of my customer looks bad if the user doesn't add an title at the top of every page.
I want to write a function to add an H1 tag automatially if H1 tags are not present.
**This doesn't work!**
function auto_dummy_titles($content) {
if (strpos($content,'<h1>') == false) {
echo '<h1>PLEASE ADD H1 TITLE TO THE PAGE</h1>';
}
return $content;
}
add_filter( 'the_content', 'auto_dummy_titles');
**It does work just if I write 'h1' instead of ''** Why? | I don't understand why your "titles" are in the post body content, but you should not be `echo`ing content from that filter. You should be creating and returning a string.
function auto_dummy_titles($content) {
if (strpos($content,'<h1>') === false) {
$content = '<h1>PLEASE ADD H1 TITLE TO THE PAGE</h1>'.$content;
}
return $content;
}
add_filter( 'the_content', 'auto_dummy_titles');
The function does work though. I can't help but think that the problem is that you should be checking the actual post title for a title and not the post content. | stackexchange-wordpress | {

Custom Dashboard Home Screen Options
I want to make the entire Homepage on the Dashboard empty and add in my own custom screen options. How do I go about doing this? Do I create one from scratch or edit what's already there? Is there some kind of codex for this, I'm not even sure what they're called...
For example, If I just wanted to add a small message to the Dashboard Homepage `"Hello World"` how would I go about doing this? | Replacing the dashboard and adding to the current one are both accomplished with plugins. Fortunately, some pretty smart folks have already figured it out for us...
To completely rewrite the Dashboard, you'll need to create a new page and redirect requests to the built-in dashboard page to your custom one. Fortunately, someone has already figured this out and wrote an excellent post about how to do it over at <

Archive template for custom post type only lists first 10
Here is my template for archive-people.com:

<?php
endwhile;
endif;

<?php get_footer(); ?>
If I want it to display everyone, is that something I change in the template? Or is that something that I add to the functions.php file? | In `function.php`

Can YOAST SEO fields be removed from custom post type
The Yoast SEO plugin is great, but it seems to appear in more places then wanted (columns, custom post type pages, etc.). I want to remove this option because as it stands even when I ignore the fields if I save my custom post type I get several fields added to my database.

remove_meta_box('wpseo_meta', 'reservation', 'normal');

Where to place PHP for shortcodes

How could I write a get_categories_by_year() function?
I need to write **a function to get all the categories for a given year**. Since the creation date of a taxonomy isn't stored in the database, I'm not really sure what to do.

Why links are not linked if edited comment?
I am using the plugin `front end editor` to edit posts.. This works very well in posts, where all links are perfectly visible if I have edited a post. For some reason, if I edit a comment and there are links in the post, I can't see the links and can't click on them because it's not linked.

Is there a solution without having to refresh the page? Why is this happening at all? | The plugin author has solved the issue. He says:
> I have encountered this bug before, but I just now realized what's causing it: the 'comment_text' filter is not applied on the updated comment content. The make_clickable() function, which makes the links in the content clickable, is hooked to this 'comment_text' filter.

As a plugin developer, how to deal with theme developer loading jquery from google?
Theme developers like to deregister wordpress jquery and load jquery from google instead.
I've been told it is for speed and I agree.
This usually is not a problem **for me** since I always use **jQuery** instead of **$**.
But I do see some plugins try to use **$** , well, it generates javascript error and also makes my plugin not working. As a result, clients blame on innocent me.
Sometimes my js code depends on the version of wordpress jquery but theme developers tend to load **a specific version** from google.
Even though the theme is updated, they may not update the jquery version, not to mention an old theme.
**What should I do in such situations?**
Actually, I'm thinking about, maybe I should use Zepto.js instead and include it in my js code.
p.s. good news, wordpress 3.6 doesn't allow deregister jquery in its backend. | Any Theme developer that dequeues core-bundled jQuery in order to enqueue some other version - _any_ other version, bundled, CDN, etc. - is `_doing_it_wrong()`, period. Core, active Theme, and active Plugins all rely on a _known version_ of jQuery being available.
What to do about it?
1. Tell the Theme developer that he's `_doing_it_wrong()`, and ask for a fix.
2. Tell your Plugin users to use a Theme hosted in the official WordPress Theme directory, since every Theme hosted there is prohibited from dequeueing core-bundled jQuery
3. Instruct your Plugin users how to override the Theme's jQuery override, via a site functionality Plugin that dequeues the _Theme's_ custom jQuery, and _re-enqueues_ core-bundled jQuery
4. Instruct your Plugin users how to patch the Theme's incorrect jQuery implementation, by adding _no-conflict wrappers_ | stackexchange-wordpress | {

Custom post types: change "read more" text
I'm developing a website that has a blog section as well as a "free monthly download" section set up as a custom post type. On the home page I'm displaying excerpts with "read more" links for both the most recent blog post and the most recent monthly download (these are in separate loops).

}

Any suggestions for how to have different "read more" text for the blog post excerpts and the custom post type excerpts?

How to do that in WordPress? | I'm afraid that you can't do it this way.
`wp_redirect` is a fancy way to send header `Location` and the second argument of this function is request status, and not custom variable. (404, 301, 302, and so on).

if ( $post_id ) {
$variable_to_send = '1';
wp_redirect( home_url() .'?my_variable='.$variable_to_send );
exit;
}
Then you can use these variables as `$_GET['my_variable']` or register it as custom get variable. | stackexchange-wordpress | {

How Does Wordpress Remember Metabox Positions?

Set posts per page for parent category and it's all children

}
}

Also, why is the uploading failing? | When you uploaded an image within the Edit Page screen for a page with a date of 06/01/2013, the media uploader will use the date of the page to set the sub-directory within the uploads folder.
This is expected behavior because the media uploader passes the post_date to the wp_upload_dir() function. See <
If you were to upload the image using just the media uploader, but NOT within a page or post, the file would be moved into the appropriate folder for the current date.

i found this css style in css stylesheet od TwentyThirteen theme, i search a lot in WP forum and w2schools and even w3c but i can't find any thing like that.
what that means | It is a CSS3 Substring matching attribute selector. See section 6.3.2. Substring matching attribute selectors in the W3C document: Selectors Level 3.
Quote:
> [att*=val]
> Represents an element with the att attribute whose value contains at least one instance of the substring "val". If "val" is the empty string then the selector does not represent anything. | stackexchange-wordpress | {

Catchable fatal error on 3.6 update
Trying to debug the situation. Getting close, but will need a little help!!
Here is the error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/website/public_html/wp-content/themes/Alexia/lib/functions/common.php on line 97
And my code from the error:
// no cache files - let's finally resize it
$new_img_path = image_resize( $file_path, $width, $height, $crop );
line 97--> $new_img_size = getimagesize( $new_img_path );
$new_img = str_replace( basename( $image_src[0] ), basename( $new_img_path ), $image_src[0] );
// resized output
$vt_image = array (
'url' => $new_img,
'width' => $new_img_size[0],
'height' => $new_img_size[1]
);
return $vt_image;
}
// default output - without resizing
Thanks in advance NINJAS!! | `image_resize` (deprecated) is returning an error object so really, the problem is here: `$new_img_path = image_resize( $file_path, $width, $height, $crop );` Something is wrong with that line and you are not checking whether the return value is an error object or a string before trying to use the return value as a _string_.
You did not post any code that might help me work out what is wrong with `$new_img_path = image_resize( $file_path, $width, $height, $crop );` but at the very least you should do:
$new_img_path = image_resize( $file_path, $width, $height, $crop );
if( !is_wp_error()) {
$new_img_size = getimagesize( $new_img_path );
// ...
Converting to use `WP_Image_Editor` would be wiser though. | stackexchange-wordpress | {

Twenty Eleven Theme
I have edited the pages and categories to all look the same and have a right sidebar, so when I click to a page or category they are same layout and also search results and archives and tag archives.
However when I click on the post title or posted on date the layout is different (no sidebar).
Does anyone know how I can make this look the same as other pages/categories with the right sidebar or which file I need to edit in the directory? | Add
<?php get_sidebar(); ?>
to `single.php` in the same place as the other files, i.e. right before
<?php get_footer(); ?>
You also need to go to style.css, and remove the margins for .singular and .singular #content, .left-sidebar.singular #content.
In version 1.5 of this theme css only has,
.singular #content,
.left-sidebar.singular #content

Creating Featured Content Boxes
I know there are plenty of plugins to do sliders out there but I'm looking for something slightly different and I've come up with no luck for a solution.
Basically, what I am trying to accomplish is to have a set of images (thinking of around 4) that sits statically above my content. Preferably it would pull the featured image and the title from posts with a specific tag or category and list them up there. Basically, a slider that doesn't slide I suppose.
I've included a screenshot of what I mean. Does anyone know of a plugin that would achieve this or a good tutorial on creating something like this?
!Example | What you are describing can be accomplished with Featured Image and a simple wp_query call.
These are very core elements of a WordPress theme. You'd need to define a size with add image size, and then call it up using the aforementioned post_thumbnail.

$args = array(
'post_type' => 'post',
'posts_per_page' => 3
);
$loop = new wp_Query($args);
while($loop->have_posts()) : $loop->the_post();
echo '<a href="'.get_permalink().'">';

Woocommerce - Hide “add to cart” on free products

How to upload image without post ID using the new media uploader?
In the past when using thickbox to upload images, an image could be uploaded without having the post ID 'attached' to it by simply using the code below :
jQuery('.upload_slider_button').click(function() {
tb_show('', 'media-upload.php?post_id=&type=image&TB_iframe=true&referer=matrix-settings');
return false;
});
However, how can I achieve the same thing using the new Media Uploader which was introduced since WP3.5? I have spent the whole day searching in the internet but there isn't much resources available on this new media uploader. Most of it are focused on utilizing it in theme options / plugins.
Or perhaps there are other ways of uploading an image without having the post ID 'attached' to it and yet not using any plugins?
Thanks a lot for helping. | Well, I have finally figured it out. Using Mike's example here, I just need to put this code `wp.media.model.settings.post.id = 0` at this place :
event.preventDefault();
wp.media.model.settings.post.id = 0;
// If the media frame already exists, reopen it.
if ( file_frame ) {
file_frame.open();
return;
}

How to prevent meta data from being edited in a post?
I need to add a 'poll' to every single post automatically, and wish to do this without having to manually create a poll each time using a plugin, so I had an idea to store the poll results as meta data in the post. So each time someone votes, it saves their vote as a custom field meta value in the post.
This should work in theory, however one problem I've discovered early on is that when editing the post which contains a poll, if someone votes while I am editing and then I press Update, the results are reset back to whatever they were before I started editing, because the custom field is being saved along with the post.
Is there any way to stop a certain custom field from being saved when I update a post? Or to make it retrieve the latest value before saving it? | I would recommend you to remove custom fields meta box from the post editing page. You can do it by using `remove_meta_box()` function.

Capture post content before page renders
I'm trying to mesh Mustache Templating Engine with WordPress. So far, I have been very successful using the_content as a filter to parse my template tags e.g. `{{ something }}`.
However, if let’s say, a developer hardcodes the template tags directly into the page template e.g. loop-page, the_content doesn’t capture the hardcoded tags.
Is there a filter that will allow me to capture the content of the whole page template including the content? | WordPress does not concatenate the entire page into a string before printing it which is what would have to happen to "capture" the whole page template. Much of the page `echo`s as it occurs-- think about template tags like `the_content` and `the_title` which don't return strings. The just `echo` them.
You'd have to use output buffering to do this. That is pretty easy if you are writing the template-- `ob_start` at the beginning or `header.php` and `ob_get_contents` (or `ob_get_clean`) at the end of `footer.php`. But there are no hooks specifically at those locations. You should be able to capture most of the page with `ob_start` on a `wp_head` filter and `ob_get_contents` on a `wp_footer` filters. I'd have to play with things to dial it in. There may be a slightly better hook for `ob_start`. I doubt there is a better one for `ob_get_contents`. | stackexchange-wordpress | {

Count > 1 Navigation Slider
I have a post type `slider`, when you have more than one post to display navigation.
My code:
<?php
$count_slider = wp_count_posts('slider');
echo $count_slider->publish;
?>
<?php if($count_slider > 1): ?>
<div id="slideshowcontrol" class="clearfix">
<div id="button_prev"><a href="#" id="slideshowprev"><img src="x.gif" alt="Prev" /></a></div>
<div id="button_next"><a href="#" id="x.gif" alt="Next" /></a></div>
</div>
<?php endif; ?>
But it doesn’t work. Why? | This is a basic PHP error, you need to turn on debugging.
`$count_slider` is an _Object_ and not an _Integer_ which is what you are checking for, since you seem to want to compare published posts anyhow , write it like:

how do I get the date in a date archive page
In archive.php, if it is a date archive, can I get the date using a function?
Consider a url like this: myfirstsite/2013/08 - I want to get the 2013/08 | Use `get_query_var()` to get the date parts:
$year = get_query_var('year');
$monthnum = get_query_var('monthnum');
$day = get_query_var('day');
In `wp_title()` a call to `get_query_var('m')` is used for the month too, but I got always just a `0` as value even on an URL like `/2008/09/05/`.
If you want to print the month name, use:
$GLOBALS['wp_locale']->get_month($monthnum);
The month name will be translated by WordPress then.
There are also four conditional functions you can use:
is_year()
is_month()
is_day()
is_date() | stackexchange-wordpress | {

Highlight current tag using get_tags()

foreach ($tags as $tag) {
echo '<li><a href="' . get_tag_link( $tag->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $tag->name ) . '" ' . '>' . $tag->name.'</a></li>';
}
}
?>
</ul>
I'd like to apply `<li class="active-tag">` to the list item that contains the active tag in the code above - can anyone help me with that please?
Many thanks
Osu | Compare `$tag->term_id` with the value from `get_queried_object_id()`. You have to cast the former to integer, because it is provided as a string for no good reason.
<ul id="blog-tags">
<?php
$tags = get_tags();
if ( $tags ) {
foreach ( $tags as $tag ) {
echo '<li>';
if ( (int) $tag->term_id === get_queried_object_id() )
echo "<b>$tag->name</b>";
else
printf(
'<a href="%1$s">%2$s</a>',
get_tag_link( $tag->term_id ),
$tag->name

How to redirect logged out users to specific page?
I have a question and a technical issue in wordpress. That is, i have a login form on my website to allow visitors to login to see special content. The question goes here, when the time they log in, i am managed to redirect them to a targeted page. When the time they logging out from the member zone, i am out of idea how to send them to a different targeted page.
In my function.php file, I have this code:
add_action('wp_logout',create_function('','wp_redirect(home_url());exit();'));
How to add the page url that i want to redirect them to this code above? I am just beginner in php. Hope to get some guidance. | `home_url()` will accept a parameter that will be used in the creation of the URL.
The bare minimum solution would be:
add_action(
'wp_logout',
create_function(
'',
'wp_redirect(home_url("/path/to/page"));exit();'
)
);
`site_url()` will also accept the same parameter and may be (probably is) a better choice.
I believe that using either of those will make the link dependent on permalink settings. I don't think that those function will translate between different settings, though I have not tested that.
I would suggest using `get_permalink()` with an explicit page/post ID.
add_action(
'wp_logout',
create_function(
'',
'wp_redirect("'.get_permalink(1).'");exit();'
)
);
Note that you don't need `home_url()` or `site_url()` since `get_pemalink()` will generate the complete URL. | stackexchange-wordpress | {

get_posts - get all posts by author id
I want to get all posts by certain author id (current user). Later, I want to pick the first post made by this user (ASC). I guess I do not use the right arguments in get_posts, am I? $current_user_posts always contains an Array with all blog posts in multiple different WP_Post Objects.
global $current_user;
get_currentuserinfo();
$args = array(
'author' => $current_user->ID, // I could also use $user_ID, right?
'orderby' => 'post_date',
'order' => 'ASC'
);
// get his posts 'ASC'
$current_user_posts = get_posts( $args ); | I'm a bit confused. If you want to get onlya element from the posts array you can get it like this:
* reset($current_user_posts) - first post
* end($current_user_posts) - lat post
But if you want to get just one post with the `get_posts()` you can use the `posts_per_page` argument to limit the results.
$args = array(
'author' => $current_user->ID,
'orderby' => 'post_date',
'order' => 'ASC',
'posts_per_page' => 1
);

Hide Pages WooCommerce
I would like a condition such as the following:
1) User is logged. Select Page Shop and displays all content. 2) If user is not logged. Select Shop page, they are redirected to another page, for example Sign Up page.
I hope it is possible. I have tried many plugins but failed. At the moment the only one that works with WooCommerce is s2Member, but it is overkill for my purpose.
Thanks in advance for any help. | You can do this by using
1) is_shop fx
2) template_redirect action hook
3) wp_safe_redirect fx
add_action('template_redirect','ravs_shop_for_login_user');

//check user in shop page and not login
if( is_shop() && ! is_user_logged_in() )
wp_safe_redirect( home_url() );// enter your url here where you want to redirect page if user on shop page and not registered

How do I use wp_get_recent_posts?
I'm trying to display the title and excerpt of the most recent 8 posts on the sidebar.
I'm getting a list where:
* All items link to the oldest post
* All titles are "id number of a post that should be displayed"+"oldest post title"
* All excerpts are from the oldest post
* * *

$args = array( 'numberposts' => '8' );

<div class="title"><p><a href="<?php the_permalink($recent["ID"]); ?>"><?php the_title($recent["ID"]); ?></a></p></div>
<div class="subtitle"><?php the_excerpt($recent["ID"]); ?></div>
</div>
<?php
}
?> | Don't use the 'helper' methods, they tend to cause more trouble than they're worth.
Any time you want to grab posts, be it the latest, the oldest, in a category etc, use a `WP_Query` loop, here is its standard form:
$query = new WP_Query( $args );
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
// do stuff
}
wp_reset_postdata();
} else {
// none were found
}
This is what `wp_recent_posts` will be doing internally, although it isn't doing it very well. So save the above to an autocomplete macro in your editor | stackexchange-wordpress | {

Editing Theme Files on Wordpress.com-hosted Site
I'm doing some work for a client on her Wordpress.com-hosted site. I'm used to only working on self-hosted WP sites, and I know how to edit the theme files there, but I'm not sure if it is possible to do this on a Wordpress.com-hosted site.
I'm trying to change the way that blog posts are displayed when listing posts from a given category, which I would usually do by going into the theme and editing the relevant php file. Is this not possible with this type of site?
Thanks! | With WordPress.com you can edit a theme's CSS styles* _, fonts_ *, or other display options offered under the theme's Appearance->Customize menu. You do not have access to edit any of the theme's php or template files.

View category in the preview of Theme Customizer
I am building a theme which Theme customizer changes colors, sizes, etc. and has also the option to choose a category and style that category specifically.
How can I display that category in the preview (only when the user is changing the corresponding options) instead of the default home/front page displayed by default?
**EDIT**
I can access the preview window with customize_preview_init, but I can not apply wp_redirect, which I guess could be a way. | I ended up with this solution:

function mytheme_customizer_live_preview() {
require_once('library/preview.php');
}

2.What I had to do is modify the query as I would normally do in the page, so just do it in the preview (inside preview.php):
function modify_query($query) {
$category = get_theme_mod( 'mytheme' )['categories'][0];
$query->set('cat', $category);
return $query;

Query parsing only author ids
I need array only all author ids from the loop, each one only once if possible and out of all posts in the loop. Any suggestions? | Assuming that you have an array of post objects in `$my_posts`...
$authids = array_unique(wp_list_pluck($my_posts,'post_author'));
What you will get are the post authors for the _current page of posts_ , not the post authors for all of the posts. If you want the authors for all of the posts you will have run another query.
To run a new query based on the main query in `$wp_query`...
$this_query = array_unique($wp_query->query_vars);
$this_query['posts_per_page'] = -1;
$new_query = new WP_Query($this_query);
$authids = array_filter(wp_list_pluck($new_query->posts,'post_author'));
var_dump($authids); // debug
_**I caution you against this.**_ You could be querying hundreds or thousands of posts. That could be very inefficient or even cause server failures, depending on the server and the load. I am almost certain that there is a better way to do this if you think it through and alter your architecture.

How to display a widget on a page with no theme?
I would like only a widget to appear on a page, is this possible?

Essentially if there was no widget added it would be a blank page. Is this possible? | You should read this. It's completely possible, but you have to go through the right process.

Remove /author/ from the author profile url

See, with your setup, then given a URL like < WordPress has no way to distinguish whether "whatever" is an author or a Page.

Safe to say WordPress security releases don't have database upgrades
Since all security releases are based on last released codebase + security patch, I think its safe to say WordPress security releases don't have database upgrades, but I figured I will ask my fellow developers here.

And yes, some of the point releases (including 3.5.2) contained "database upgrades".
Now, it is only very rarely that the actual database _schema_ changes, but there are minor bugfixes in every point release, and sometimes they require a little database action. So while 3.5.2 had seven security related patches, it also contained a fix for multisite installs to fix an invalid site-option. This required a minor bit of code to change the data in the database.
