How to remove date, author and comment count from Chameleon search results page
I would like to remove the following from the search results page, I'm using the ET Chameleon theme which doesn't have a search.php file in the editor section. Any help greatly appreciated.
Posted by auscov on Feb 22, 2013 in | 0 comments | If the theme doesn't have a `search.php` file, `index.php` will be used.
> ### Template_Hierarchy
>
> Template file used to render a Search Results Index page
>
> 1. **search.php**
> 2. **index.php**
>
_[update]_
Use the following to print the current template being used to render a page:
add_filter( 'the_content', 'so_9405896_the_content_filter', 20, 1 );
function so_9405896_the_content_filter( $content )
{
if( is_admin() || !current_user_can( 'delete_plugins' ) )
return $content;
global $template;
$the_templ = '<strong style="background-color: #CCC;padding:10px">TEMPLATE = '
. basename( $template ) . '</strong><br />';
$content = sprintf( $the_templ . '%s', $content );
return $content;
}

post_count not working
I've fixed my initial problem but I'd like to know what I was doing wrong.
<?php
$args = array(
'post_type' => 'page',
'post__not_in' => array( $post->ID ),
'post_parent' => '43',
'post_count' => '3',
);
$my_related_posts = new WP_Query( $args );
?>
Displays 4 results, where I expected 3. I fixed the problem by doing:
<?php
$args = array(
'post_type' => 'page',
'post__not_in' => array( $post->ID ),
'post_parent' => '43',
'post_count' => '3',
'posts_per_page' => '3'
);
$my_related_posts = new WP_Query( $args );
?>
But what was I doing wrong? Changing post_count seemed to have little or no effect. Thanks | `post_count` is not a parameter of WP_Query argument.
`post_count` is a property used to get the number of posts being displayed. For example, `echo $my_related_posts->post_count;` will display the number of posts being displayed. | stackexchange-wordpress | {

Too many login attempts
Since a week or two I keep receiving the following automatic email message sent from my WordPress website, and I'd like to know if it indicates any security hole and if there's anything I can do to stop it :
"A host, 79.148.238.85(you can check the host at < has been locked out of the WordPress site at < until Friday, February 22nd, 2013 at 9:41:54 am UTC due to too many login attempts.

<
installed with the `Enable login limits` feature activated here `/wp-admin/admin.php?page=better-wp-security-loginlimits`. You can configure the plugin to stop sending you these messages. But you should have the feature activated, since most likely some **bot** is trying to login. Or even consider to blacklist this IP in the plugin via the `Ban` page in `/wp-admin/admin.php?page=better-wp-security-banusers` (if you are sure this is not an actual user in your Wordpress trying to login)

Permalinks that go to a specific template
This is actually my first question here, so hello to everybody in this community!
I have developed a theme with a custom post type and a template (lets call it "my_template.php") that shows posts of this custom post type in an archive-like fashion.
What I'm trying to achieve is to make a permalink in the navigation of the site that goes to a specific template (like "my_template.php") and ignoring the wp template hierarchy.
How could one do that?
Note: I've already checked out This answer, but that one didn't really help and provided only a workaround.

Plugin won't activate, fatal error (widget class not found)
I've been putting together a simple WordPress plugin that employs a sidebar widget and shortcode. One user has reported the following error when trying to activate the plugin on their local WP installation:
> Plugin could not be activated because it triggered a fatal error.
>
> Fatal error: Class 'Example_Widget' not found in /Applications/MAMP/htdocs/wordpress/wp-content/plugins/exampleplugin/exampleplugin.php on line 30
Here's the code in `exampleplugin.php`, beginning with line 29:
$example_plugin = new Example_Plugin;
$example_widget = new Example_Widget;
class Example_Plugin {
...
}
I'm fairly new to OOP in PHP, and can't figure out what's causing a fatal error for this user. The plugin works fine for me, making this all the more mysterious. | You should not need to instantiate the widget class at the top of your code, because of the register_widget function hooked from your main class does that work for you.

WordPress Page Reload Takes forever during theme development
OK, I'm hacking my way through my first theme (while reading Prof. WP Design & Development 2nd Ed.) and ....
EVERY TIME I change -for example- a p tag or a div tag or a css rule, when I then go to reload the page to see changes ... I....wait....and....wait.... for the dang page to reload!?!
I'm seeing "cache issue", but I'm unsure of exactly what that means, so I'm not sure that IS my problem.
IF this is a cache issue, can someone please explain exactly _what is going on under the hood_ during the reload? And just what I can do about it?
Can someone break this down a bit for the noobs. :)
thanks, sleeper | From the comments above, it seems the problem is caused by a plugin. You can try to search for the error message (cache issue?) within the plugin files. Some editors and IDEs have a function "file search" which searches in every file. E.g. in Notepadd++ you can do a file search by hitting [ctrl]+[f].
If you found the error message, deactivate the plugin and install an alternative plugin. | stackexchange-wordpress | {

Remove .htaccess portion upon plugin deactivation?
I have a plugin that inserts some rewrite rule in the .htaccess file. However, upon deactivating it, doesn't remove said rule. The rule is nested in `# BEGIN My plugin` and `# END My plugin`.
I want to create an uninstall.php file for this plugin to remove the rule created on acrivation.
I've never done this before. I suppose I can get the .htaccess with
$htaccess = dirname(__FILE__) . '/../../../.htaccess';
should I use a regex or is there a proper way to remove a specific rule from the .htaccess? | How do you add your rewrite rule?
If you are adding it manually (opening the .htaccess and adding the lines by yourself in php) then you are also supposed to remove it manually. As you suggested the best way would then be to use regex.
If the rewrite rule was added through the Wordpress API using add_rewrite_rule() you are able to remove it using flush_rewrite_rules(). You could use it like this:
register_activation_hook( __FILE__, 'myplugin_activate' );
function myplugin_deactivate() {
global $wp_rewrite;
unset($wp_rewrite->non_wp_rules['the-string-you-passed-as-param-to-add-rewrite-rule']);

Nonce check causing issues when creating new post
I have created a new custom post type and some custom fields for it. My function for saving the custom meta fields fires on the 'save_post' hook.
The problem is that I am getting a warning when I go to add a new post:
Notice: Undefined index: my_meta_box_nonce....
// verify nonce
if ( ! wp_verify_nonce( $_POST[ 'my_meta_box_nonce' ], basename( __FILE__ ) ) )
return $post_id;
When I enter the post details and hit publish the error is not displayed, it's only there when I create a new empty post. What's wrong here?
My code is almost identical and based on this tutorial: <
In the comments of that tutorial it seems that there were others who had the same problem, but there is no solution given. | I know that this is not the only tutorial that has code that check nonce for meta boxes but this is truly idiotic. Nonce should be checked per the whole action not per parts of it and if your save_post hook was called it means that the save nonce was already checked and found valid, so There is no need for more security checks.
My advice is to simply remove anything related to nonce from your metabox code, but if you will feel better having it around just change the code to
// verify nonce
if ( !isset($_POST[ 'my_meta_box_nonce' ]) || !wp_verify_nonce( $_POST[ 'my_meta_box_nonce' ], basename( __FILE__ ) ) )
return $post_id;
which will bail out when no nonce was supplied or the nonce failed validation | stackexchange-wordpress | {

How is it possible to list custom post types by "category" like with simple posts?
I created a custom taxonomy, "partners". I would like to categorize these items, so I created a custom post type with a taxonomy.
register_taxonomy("partners-category", array("partners"), array("hierarchical" => true, "label" => "Partners", "singular_label" => "Partner", "rewrite" => true, "slug" => 'partners-category'));
I would like to list these posts by categories for example: categoryname-category.php. I know it's working only with posts, so what's the best way?
Thank you very much and sorry, I'm newbie. | You have to create an template file called taxonomy-{name}.php to show the posts assigned to a custom taxonomy. So in your case it should be taxonomy-partners-category.php . Category related archive pages work only with "Posts".

wpdb-> not adding prefix to custom table
I know it should work with custom table and I think it worked in previous development I believe. But this time I don't know whey it is not getting custom table with `$wpdb->tablename`
Code:
global $wpdb;
$items = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM $wpdb->review_media"));
This is not giving any result but when I tried with `$wpdb->prefix than it works
$wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM ".$wpdb->prefix."review_media"));

Does post-meta belong in header?

What about the post image? Could that be part of the header? | The w3 specification says that only h-tags are allowed inside of the hgroup-tag. The basic purpose of it is to group a main-headline and a sub-headline together.
<hgroup>
<h1>My maintitle</h1>
<h2>Subtitle of my content</h2>
</hgroup>

query_posts and custom taxonomy posts order
i have a custom taxonomy defined for "Projects" and a page that shows all the projects. In this page there's a jquery filtering menu (isotope). Initially the page must show all the projects but chronologically ('chronological' is a category and 1970, 1980, 1990, etc are subcats for a Projects element) ordered in DESC mode.
Now the query that initially shows the Projects in the page is
query_posts('post_type=portfolio&project-type='.get_post_meta($post->ID, 'portfolio_page_cats', true).'&posts_per_page=-1&orderby=menu_order&order=ASC');
There are a lot of questions about this argument, i know. Please, what is the best way to do that?
Regards, | If you are trying to order your posts by taxonomy terms, it's not technically possible in one query (since multiple terms can belong to multiple posts - which means that WordPress _cannot_ support 'orderby' for taxonomies or terms because there are potentially more than one).
Your solution would be:
1. Fetch a list of your (sub)terms and loop through them.
2. In each term loop, run query_posts() to fetch only posts attached to the current term.
3. In each term loop (after the query), create your content-output loop to display your posts. | stackexchange-wordpress | {

Can't remove menu items added by plugin
I am trying to remove menu items from the backend but for some reason I can't remove specific menu items added by plugins. For example, I can use this line to remove the plugins page and it works just fine:
remove_menu_page('plugins.php');
I have a plugin, CW Image Optimizer, that adds a sub menu under the Settings menu. The php file the plugin uses is named cw-image-optimizer.php. If I use the following line to remove the sub menu it doesn't work:

Is there something specific I need to do to remove menu and sub menu items added by plugins? | I'll assume you're calling it in your functions.php file?
If that's the case, likely the plugin is adding the menu item after you're call is being called. Try placing it in the admin_init() hook, at the very end.

function remove_wp_menu_items() {
remove_submenu_page( 'themes.php', 'theme-editor.php' );

Organize Existing Posts from the Admin Area to a New Category
I want to create and admin area that allows you to add, reorder, and remove existing posts to a 'featured' category by selecting from a dropdown menu that has a list of categories and posts in that category, preferably with a drag and drop functionality.
Would this be done with a custom post type? If so, can anyone direct me to an article somewhere that can get me started on doing this? | While it's not _exactly_ what you're asking for, check out Zoninator. It does everything you're asking except that it doesn't use categories. I'm guessing you just wanted to use categories to target a featured area of the site, and if so, this does that extremely well.

What is user_trailingslashit() for?
What does the `user_trailingslashit()` function do, and when should I use it? How is it different from the `trailingslashit()` function? | The `trailingslashit()` function adds a `/` to the end of a URL if it lacks one.
`user_trailingslashit()` uses the permalink template as set under _Settings > Permalinks_ to decide whether to add or remove the trailing slash from the end of the URL
For example, if you had the permalink format set to `/%year%/%monthnum%/%day%/%postname%/` (note the trailing slash), `user_trailingslashit()` would append a trailing slash to the URL passed in as the first parameter.
If the permalink format was `/%year%/%monthnum%/%day%/%postname%` (no trailing slash), any trailing slash on the URL would be stripped off.
Basically, `user_trailingslashit()` forces the URL to be consistent with what is set in the permalink preferences. | stackexchange-wordpress | {

Adding Second Plugin Author
**Background:** I have a few plugins in the WordPress directory and have recently made the decision to team up with another individual to grow one plugin faster. I'm planning on adding him as a plugin author, but I want to be sure that if I do so there's no risk of me "losing control" of my plugin.
**Question:** If I add another author, is there any way that the new author can remove me as plugin author? Can they upload the plugin with their username and password, or am I still the only one that can upload changes?
I couldn't find anything on this topic, and I'd really hate to have my plugin stolen as I've become somewhat attached to it. | You can add the author as contributor and all I know, he does not get automatically write access to your svn repository.

How to access a variable on all page?
I added a variable to my functions.php file:
$options = get_option( 'simple_options' );
I can access to this variable on every page, but If I call it in the footer.php it's not working. How to fix that? | Generally, you cannot access local variables in a function from outside the function, so this...
function func() {
$var = 2;
}
$var = 1;
func();
echo $var;
would result in "1".
To make a global variable, you can do this to make `$option` available outside `functions.php`:
function func() {
global $option;
$option = get_option( 'simple_options' );
}
However, I cannot recommend it, since every other script may change the value. You can use a define:
define('MY_OPTION',get_option( 'simple_options' );
And in your footer:
echo MY_OPTION; // note that there are no quotation marks
But also this wouldn't be that neat, since you'd have to make sure no other script defines this `MY_OPTION` and you cannot change it later on.

Recommended sidebar / content widths

If you plan on running ads, please check the ad width requirements and use that as your baseline. For example, if you are running AdSense ads and the ad requires 300px, then make sure that sidebar has a minimum width of 300px or your might break your layout or the ad might not show.

Is there a solution to this? Thanks. | Browsers will cache any files so it's hard to know without more detail _which_ files are your issue.

Should i use _n for pronouns in translation?
**I use _x() now! I accepted the answer just because he understood right and was first. So don't get confused!**
$like_me_on = __('Like me on %s', 'my-plugin');
$like_us_on = __('Like us on %s', 'my-plugin');
$follow_me_on = __('Follow me on %s', 'my-plugin');
$follow_us_on = __('Follow us on %s', 'my-plugin');
$my_x_profile = __('My %s profile', 'my-plugin');
$our_x_profile = __('Our %s profile', 'my-plugin');
I have this code and i read about _n() and saw only examples with $count on wordpress codex.
The text is for a bunch of social services that will later be %s, if i would use _n then i would have this variables combined, but the translation string would be more complicated to read. So what is best practice and is this intended for pronouns or just for numbers? | It's interesting idea and I think that such approach will work for you. What I would recommend you is that it will be better to use constructions like this:
// $singular = 1 - for 'me', 2 - for 'us'
$like_on = _n('Like me on %s', 'Like us on %s', $singular, 'my-plugin');
In this case it will be easier to understand how to translate the phrase.

Using Underscore Templates in WordPress

Add robots.txt to root
I have a new Wordpress 3.5.1 install (hosted on Dreamhost FWIW) that I do **not** want to be indexed by search engines. I would like to serve a simple robots.txt with `Disallow: /` for all user agents.

Is there a way to have Wordpress automatically generate and serve an appropriate robots.txt file? If not, what is the best way to configure it to serve my own static robots.txt file? | First of all, in order for Wordpress to generate a robots.txt for you you must be using a non-default permalink structure.

Get Posts From A Certain Post Type In An ID Array

'fields' => 'ids', // if you only want the Post IDs

Showing all the posts in one page?
There are over 200 posts tagged with the keyword "Apple."
Each tag page -- example.com/tag/apple/page/2/ -- shows 10 posts.
So there are 20 tag pages.
Is it possible to show all these 200 post (links) in one page? I don't want to show any of the excerpt -- just consolidate all those 200 links in one page.
Appreciate your help! | This is what I would consider the correct solution, and is the solution alluded to by Milo's comment (if I am not mistaken).

$qry->set('posts_per_page','-1');
}
}
add_action('pre_get_posts','alter_ppp_for_tags_wpse_88337');
Using `query_posts` will cause two requests to the database-- the main query, and the query triggered by the use of `query_posts`. By using a filter on `pre_get_posts` you alter the main query before posts are fetched and thus only hit the database once.

Resizing old post thumbnail images

set_post_thumbnail_size( 475, 475, true );

Infinite scroll loads new posts several times

Using Wordpress as a Mobile App Backend
I'm searching for a fast way to develop a backend for Mobile Apps. The idea is to use Wordpress as a backend.
My problem is: How can i serve the information to the Mobile App? I saw the JSon plugin but you can't use it for custom post types.

The problem is that in this case the link is corrupted. It always links to the very first post. What I am doing wrong? | The Problem is that you query for Post Status `null`.

strip last comma from get_the_category
foreach((get_the_category()) as $category) {
echo $category->cat_name . ', ';
}
So I'm echoing it like this because I don't want the categories to appear as hyperlinks, I just want the cat names.

I tried 'stripping' it (php seriously confuses me small design mind)
foreach((get_the_category()) as $category) {
echo $category->cat_name . ', ';
echo rtrim($category, ", ");
}
That didn't trim it though. | There are two ways to solve this issue. You need a clean array of category names for both, so let’s start with that:
$cat_names = wp_list_pluck( get_the_category(), 'cat_name');
`$cat_names` is now an array with just the names:
Array
(
[0] => aciform
[1] => Cat A
[2] => Cat B
[3] => Cat C
[4] => sub
)
Now you can use the simple way:
echo join( ', ', $cat_names );
Result: _aciform, Cat A, Cat B, Cat C, sub_
But my recommendation is to use the grammatically correct list, use `wp_sprintf_l()`:
echo wp_sprintf_l( '%l', $cat_names );
Result: _aciform, Cat A, Cat B, Cat C, and sub_
`wp_sprintf_l()` will use a localized separator for the last two items, so in a German site this would output: _aciform, Cat A, Cat B, Cat C und sub_.
And you don’t even have to care about the correct translation – the proper separator is part of the regular language files. | stackexchange-wordpress | {

What's the best way to implement AJAX in WordPress?
WordPress has a framework in place for handling AJAX which is well documented here: <
My concern with this is that every time you execute an AJAX query, (even if you want to return a single field from a table) this framework instantiates the whole WordPress stack, including any plugins and theme functions that may exist on your site. This strikes me as a pretty heavy method to perform what may end up being a pretty simple function.
Typically a lot of WordPress sites run on shared hosting and don't have a whole lot of processing power, so, based on my experiences, a reponse time of 2 seconds to a WordPress hosted AJAX call is not uncommon.
Any recommendations on how to improve on this response time? | The crude alternative most people resort to is the one where you add a file and include several levels up. This is arguably worse for performance if not just as bad.
But there is a variant that works better, if we create our own AJAX entrypoint URL, and specify:
define( 'SHORTINIT',true);
Then include the WordPress environment, we can skip over the majority of the loading process. This is the way to go if you want super zippy AJAX requests. The downside is that we have to load some things ourselves, and some steps of the loading process are never executed.

Saving Taxonomies to Post Revisions
In a custom post type, I first got all the revisions using `wp_get_post_revisions()`.
I looped through, and compared metadata and postdata to see the differences between the two. However, it seems that when I employ the same strategy on `get_the_terms()`, I'm getting the proper taxonomies for the actual published post, but the revisions do not have any taxonomy data.
How can I save taxonomy information for revisions? | WordPress only supports revisions for post content, not terms.
To create a system that monitors changes in post-term relationships over time, you would have to write a plugin that explicitly handles that.
If you're interested in going down that route, you would probably need to use the save_post hook to save term data (saving as serialized post meta would probably be best) and the add_meta_box hook to output a list of term updates/revisions.
This would be decoupled from the existing revision system unless you wanted to get even more technical, but it might be the most expedient way to get what you want. | stackexchange-wordpress | {

www.tenspeedgreens.com
where it says 'ten-speed greens' is where i would like the custom text to be displayed.
thanks | For something like this, you can use WordPress's built-in "Custom Fields" feature.
**Step 1**
On your edit page, **create a new Custom Field** (if you don't see the Custom Fields box on your edit screen, click on the grey"Screen Options" tab at the top-right of the page, and make sure the "Custom Fields" box is checked). The name can be anything, for example let's assume you want to use "Page Description"...
**Step 2**
Finally, **output that custom field into your theme.** Do this by using the following snippet wherever you want to output the custom description text...
<?php echo get_post_meta(get_the_ID(),'Page Description',true); ?>
One more thing... WordPress will remember the name of your Custom Field. Any time you want to use it on a page or post, you can select the name from a drop-down and then enter your description for that page/post. | stackexchange-wordpress | {

Wordpress update and plugin install not working

Display 1 category only with get_the_category (by ID or slug)
After hours of unfruitful Googling, I am asking for your help on this issue.

$category = get_the_category();
if($category[0]){
echo '<a href="'.get_category_link($category[0]->term_id ).'">'.$category[0]->cat_name.'</a>';
}
?>
Thank you for your contributions. | I think you could do something like this:
$categories = get_the_category();
$displayed_category_id = 1; // set this to the category ID you want to show

if ( $displayed_category_id == $category->term_id) {
$output .= '<a href="'.get_category_link($category->term_id ).'" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '">'.$category->cat_name.'</a>';
}
}
echo $output;

Allow Content Author to Publish, But Not Edit or Delete

How to stop direct HTTP POST to a PHP script?
I have a form on my site, created using Contact Form 7 with Captcha. Contents of the form when POSTed are being sent to a PHP script, the "action" attribute of the form is set to `themes/<themename>/<filename>.php`

Function to change meta value in database for each post
I have a meta key called 'prijs' in each post. The value of this meta key consist of numbers in the follow structure: 2,100.00

What's the difference between post thumbnails and featured images (if any)?
On the Codex on Post Thumbnails, I see:
> Post Thumbnails is a theme feature introduced with Version 2.9. It was quickly changed to Featured Images with Version 3.0. Post Thumbnail, now Featured Image, is an image that is chosen as the representative image for Posts, Pages or Custom Post Types.
On the changelog for Version 3.0:
> Change Media UI labels from "Post Thumbnails" to "Featured Image"
Is there any difference in behaviour of post thumbnails and featured images, or was in 3.0 only the name changed? Why did the name change? It is a source of misunderstanding, as the image size is still called `thumbnail` or `thumb`, while it on the UI everywhere says Featured Image. | This is explained in the core ticket #12554.

> We should change the UI label for the post thumbnail box on post and page editor screens.

Is There A Way To Add Another Field To Custom Post Type (Not Custom Field/Meta)?
Maybe I'm not getting the whole concept, but is there a way to modify a Custom Post Type so that it includes other 'fields' like a 'real' db table. I don't mean a Custom Field (get_meta)... I mean inside the table that can be manipulated with rules. I want to make a post type with several -mandatory- fields.
eg.
Song Record:
<Title
<Lyrics
<Date
<Length
<MP3
:end
Yeah, I can do that with a bunch of custom fields, but I was wondering/hoping if this structure could all be laid out with Register_Post_Type so it could be manipulated as a single 'object'... as one can do in Drupal.
Or have I got this all wrong?
\---JC | There is no built in way to do so. You could possibly do it via MySQL directly via ALTER TABLE but you'd have to write custom code to take advantage of this yourself. Another option is to create a new table where each set of data references a certain post. Yet again, you'd have to manage everything yourself.
My suggestion: use a plugin like Meta Box or WP Alchemy to use the custom field system that's already there. Either one creates a meta box of fields that'll save the custom post meta for you | stackexchange-wordpress | {

Add Default Wordpress Formatting To Data From External SQL Tables?
I have a number of external SQL tables that have data in exactly the way I want and I would like to use them to populate various wordpress posts with shortcodes.

and
are added.
IOW: I have a proper WP Post and I display the contents on a page it auto-magically includes
and
tags. If I copy that text to my external table and then pull that field into the same WP post using
$result = $wpdb->get_col( "SELECT my_text FROM my_songs WHERE id = '" . $song_id . "'" );
...the results has none of the `<br>` or `<p>`s unless I explicitly add them to the text.
How can I take $result above and 'format' it so that it matches the same text from a WP Post using `get_content()` ? | You can run the `the_content` filters on your data.
foreach ($results as $r) {
echo apply_filters('the_content',$r);

Wordpress add_permastruct unwanted matches
I'm working on a project which involves filtering some customs posts on the front-end. I managed to create the permalinks including a custom field, but it seems that the rewrite rule matches some unwanted pages, making them not display-able on the frontend.

$wp_rewrite->add_rewrite_tag('%competition%', '([^/]+)', 'competition=');
$wp_rewrite->add_rewrite_tag('%prize_category%', '([^/]+)', 'prize_category=');

But it also matches this one:
`

` not for `domain.com/au/param1/` ?
Thanks, George | I've been struggling all morning to solve this and found your question when searching for the answer. I'm sure it's a little late for you now but in case anyone else stumbles across this question here's the solution I found:

To:
$wp_rewrite->add_permastruct( 'competition', '/au/%prize_category%/%competition%/', array( 'walk_dirs' => false ) );

However, if oembed does not support the service (Eg. Spotify) and the user inputs the full embed code, it does not echo out anything.

Implement plugins as part of a theme

I have a package of plugins that I use on almost all of our websites (both public and internal plugins)... and plugins should _really_ remain plugins. Deploying a package of plugins is not hard or time consuming and only needs to be done once per project.
By integrating them into a theme, you lose the ability to activate/deactivate them if necessary, nor can you update them. Please consider that first.
Ok, so to incorporate them into your theme, this is what you would do...
1. Create a "plugins" folder within your theme.
2. Place both plugins in that folder.
3. Within your functions.php file, use require_once to load each of the plugins default php files (if the plugin authors correctly followed convention, the main plugin file will be the one that matches the plugin folder name).
4. Done.

Self-hosted blog Admin Panel Forwarding to WP.com

Wordpress REST endpoint with JSON for Mobile App integration
Is there some REST API that Wordpress supports, out of the box or through any plugin that exposes the same information exposed through the normal pages? (I.e. latest posts, filtering by categories etc.)
There seems to be a JSON API plugin but it seems to be very old and not maintained.
There also seems to be some plugin called Jetpack but not sure if it provides what I am looking for (seems more dedicated to content management rather than exposing it publicly).
I am trying to integrate a Mobile App with a Wordpress Blog, and I need to find the best way to transfer the information to the application in terms of performance and also displaying it right. (Any ideas appreciated) | The REST API can be used for straight-up retrieval on any blog that has enabled it. Self-hosteds require an active choice to turn the JSON interface on in Jetpack but once it's up it's wide open.
This is not necessarily appreciated by everyone, and that's somewhat understandable. I picked a blog ID at random here for the /posts/ call:
<
That's the full output. If you were trying to make life marginally harder for scrapers by only providing excerpts in your RSS feed then this pretty much undoes that. It's a pretty false sense of security - if your blog is public then it's scrapeable - but not everyone loves this fact.
For your purposes you can absolutely just use the API to pull individual posts and display them in an alternate manner. | stackexchange-wordpress | {

Display current taxonomy term when inside custom post type
Well, this should be pretty simple, however I couldn't find answer anywhere on the web. all answers I found were close but no exactly what I needed. what I need is to display just the current term of a custom post type I am in. **not all the terms just one!** (the relevant one)
this is what I'm using but it displays ALL the terms which is not good for me:
<?php
$taxonomy = 'genre';
$queried_term = get_query_var($taxonomy);
$terms = get_terms($taxonomy, 'slug='.$queried_term);
if ($terms) {
foreach($terms as $term) {
echo $term->name;
}
}
?>
remember - I would like to display it in my single post type template can anyone suggest? thanks | Ok, so I finally found what I needed here: How to get current term in my custom taxonomy in WordPress?

// Loop over each item since it's an array
if ( $terms != null ){
foreach( $terms as $term ) {
// Print the name method from $term which is an OBJECT
print $term->slug ;
// Get rid of the other data stored in the object, since it's not needed

Multiple templates for single custom post type
Does anybody know of a way to modify the wordpress template process so that a single custom post type can be displayed on two separate templates based on the value of a custom field.
For example I have a single Custom Post Type called "plans"
It is using the single-plans.php and archive-plans.php files as templates by default.
What I would like to do is use this bit of code to filter out some of the results within my loop.
<?php //Filter the results based on the presence of $var
$var = get_post_meta($post->ID, 'my_custom_field', true);
if($var !== '') { ?>
THE LOOP
<?php } ?>
This works fine but i need create two separate templates where I can test for separate $var so I can have two menu items that each call on a separate version of the template and get a unique set of results from my single CPT
Thanks, Eric | Might be side-stepping your question, but can you use get_template_part?
<?php
get_template_part( 'plans', get_post_meta($post->ID, 'my_custom_field', true ) );
?>
Then create "plans_plana.php" and "plans_planb.php" (assuming that 'my_custom_field' can have values of 'plana' and 'planb').

Thumbnails for media Library images
I have somee Item in the media library, where I want to retrieve the thunbnail from. I use the normal post thumbnail functions (tried some of them), with normal posts or cpts's the work fine.
As media library items are handled, similiar to posts, I thought the normal wp thumb function could work there, too. There are also thumbs created, as i can see on the server.
But no one fo WP's Thumb Fuunctions returns that thumb.

<?php echo get_the_post_thumbnail($post->ID, 'size-1'); ?>
The post ID is correct. The Thumbnail size is registered and works for other posts fine.
Thank YOu! | `wp_get_attachment_image($post->ID, 'size-1');`
The "post thumbnail" actually gets the featured image that is attached to the post. For an attachment, you want the attachment itself in a specific size, which isn't the same as the featured image. | stackexchange-wordpress | {

Why doesn't default Wordpress page view use force_balance_tags?
I noticed that the default WP theme uses force_balance_tags for listing posts' excerpts. This way, it doesn't cause major html breakage whenever someone writes a post like
<div><b>This is an excerpt. <!--more--> and this is more text... </b></div>
It will close tags instead of bolding everything, and breaking div.
Why doesn't the normal wordpress page do this by default, in the default theme? That way, broken page content like:
</div></div> now text is not where it's supposed to be </div> unmatched tags
would not cause unexpected behavior.
Was this an oversight, or are there certain things that break when using force_balance_tags on pages? | `force_balance_tags()` is not a really safe function. It doesn’t use an HTML parser but a bunch of potentially expensive regular expressions. You should use it only if you control the **length** of the excerpt too. Otherwise you could run into memory issues or some obscure bugs.
The other problem is: the function uses two hard-coded lists of elements for single tags and nestable tags. There are multiple places where WordPress uses such lists, and they are not kept in sync. So when you use an element that isn’t part of these lists or changed its nesting behavior you may end up with incorrect markup. | stackexchange-wordpress | {

How to order posts in an arbitrary order?
I need to list posts in a very specific order that has nothing to do with the date of the posts or the title, or anything WordPress can figure out for me. I need this order to be used when I list posts in a category and on the category archive page itself.
Is it possible to do something like this, were $idlist was an array of post ids in the order I want, and it could loop through each one?
<?php query_posts(post_id=$idlist); ?>
<?php the_permalink(); ?> etc... | First off, `query_posts` is terrible doesn't use it. It does all kinds of fun things like mess up the very useful conditional tags like `is_singular` and the like as well as mess up pagination.
Short of hooking into the `posts_orderby` filter and writing some custom order by SQL, your best bet is to use the `post__in` argument combined with the `post__in` orderby argument that was added in WP 3.5.
Example:
<?php
$custom_query = new WP_Query(array(
'post__in' => array(1, 2, 4, 5, /* whatever your post ID's are here */),
'orderby' => 'post__in',
));
while ($custom_query->have_posts()) {
$custom_query->the_post();
// use the normal template tags here
?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a>

Javascript block in Twenty Twelve theme
I am authoring a WP plugin, and I have to generate some JS (jQuery) code in "realtime". It is working fine in general, though I've stuck with one problem with the WP 3.5.1 and its default Twenty Twelve theme: there the scripts are inserted in the footer of the page, not in the header, causing my code to throw errors.
I've looked through all the theme's files (header, footer, functions), and I can't seem to find the reason for that. Looks like the `wp_footer()` is inserting the block, but I can't find any hook or anything else that tells WordPress to insert scripts there.
So, my question is: how to make jQuery and other scripts go in the header by default, not in the footer? What does make the theme work this way (maybe the default WP behavior changed?) | By default when you use `wp_enqueue_script` the script is inserted into the `<head>` section. This is usually set in `functions.php`.
The argument also has a footer option called `$in_footer`, if you set this to true, the scripts will instead be added to the footer section. In TwentyTwelve there are several calls to `wp_enqueue_script` with footer set to true.
For example:
wp_enqueue_script(
'twentytwelve-navigation',
get_template_directory_uri() . '/js/navigation.js',
array(),
'1.0',
true
);
To remove the footer calls you can `wp_dequeue_script` it, then requeue it for the header or just add `false` for the 5th parameter. <
