Not sure how I would go about doing this in WP.. related to custom tags
Okay, so I want to do something, and after searching on Google I couldn't find any answers. Maybe you guys can help.
basically, I want to assign every post with a little bit of unique identification information. Every post would be tagged white, gray, or black. **I don't want to use categories or tags because I want to display this "unique identifier" on the home page only, and not in the posts where the categories and tags are already shown.**
For example, If I made a post about white tigers, I would want to **identify it as white post** (no racism or anything intended, just an example), and display it on the home page only.
If I made a post about gray tigers, I would want to identify the post as gray, and you get the point.
_**How can I go about doing this without a plugin?_**
**TL;DR - Want to identify each post with a unique identifier, but can't use categories and tags.**
Please help! | There are two mechanisms in WordPress that would fit your use case: custom taxonomies and post metadata.
Since you have already determined that you want something close to mechanics to categories/tags (which are built-in taxonomies) it seems like custom taxonomy is a right fit for your use case.

How to highlight the current page in the nav menu?
I'm customizing a WordPress theme for my school, and I'm a bit annoyed by the fact that the current page in the nav menu is not indicated.
For example:
!enter image description here
You can clearly see that I'm hovering over a page in the nav menu, and that the page I'm hovering over is highlighted, as expected.
However, the page that I'm currently on, called "Arhiva", is not highlighted, and I think that this can be somewhat confusing.
I don't want the current page and the page the mouse is hovering over to be highlighed in the same manner though. I believe that a bold entry text in the nav menu would do just fine to separate the current page from other pages.
How can I achieve this?
Theme's current CSS can be viewed here: < | The Navigation Menus system is adding a lot of classes, including matching current page (rather intelligently, it will even try to detect custom URLs, that were input explicitly).
The simplest class to make use of is `current-menu-item`, but there are quite a few more dealing with parents/ancestors and more.

Creating a custom multilingual form
I need to create a special form for my website where users cand specify a series of data including some textfields, combo boxes and sliders (from 0 to 100). Also I need this form to be qTranslate compatible, for my website is multilingual.
What would be the easiest, cheapest approach for this?
I tried the lite version of Ninja Forms plugin but it offers very few form element types.
I also started creating my own template with the form elements but I don't know how to make it work with qTranslate. And I'm thinking this solution is maybe reinventing the wheel and there's a fastest approach than programming it myself. | > What would be the easiest, cheapest approach for this?
Simple, create one form per language.

add_shortcode( 'my-lingo-form', 'shortcode_wpse_98360');
function shortcode_wpse_98360()
{
$lingo = your_language_detection_method();
switch( $lingo )
{
case 'en':
echo do_shortcode('[form-en]');
break;
default:
echo do_shortcode('[form-other-languages]');
break;

Using post_class to style posts indivdually
I have a homepage on which I want to display the latest post different from the other posts. I haven't used `post_class` and I am not sure how to.
Would I be able to achieve what I want using `post_class`? | You should be using `post_class` (and `body_class` for that matter) but you don't need it for this. Alter your Loop on your home page to conditionally format the first post.

while (have_posts()) {
the_post();
if ($first) {
// code to format the first post
$first = false;
} else {
// code to format all the other posts
}
}
}
If all you need is a small change that can be made via CSS then you can pass `post_class` a parameter.
$first = (!is_paged()) ? 'is_first' : 'not_first';
if (have_posts()) {
while (have_posts()) {
the_post();
echo '<div ',post_class($first),'>';
// the rest of your Loop

Adding a template in WPTouch
I am creating a mobile version for a site. For that I am using WPTouch not WPTouch-Pro. Now I want to add a form in my page.
For desktop version I used template to add form. But in mobile version it's not working. When I exit mobile version form is present in my page. I saw some post which suggest to add child theme and its for WPTouch-Pro.
Since I am new to wordpress I don't have any idea how to solve this problem. | As WPTouch uses its own theme, we can't hardcode certain functionality inside the regular theme, neither in a page/post template nor `functions.php`.

Post preview gives 404 when permalinks are purely date based
I have an issue pertaining specifically to the situation in which permalinks are set to be based only on publication date. My permalink structure is as follows:
/%year%%monthnum%%day%/
When I try to preview a post, I get 404. The issue does not come up when I add other URL tags to the structure, like post ID or post name.
I have already tried to diagnose the issue and one thing that came up was that Wordpress may be treating URLs consisting only of date tags as date archive pages. Indeed, is_date() returns TRUE when a post page is displayed.
Is there a way around it that does not involve changing permalink structure? Thanks for help. | I will sum up my findings for future use by others:
1. When using permalink structure that uses only date tags, Wordpress is unable to identify a unique post because there may be more posts in any given day.
2. For this reason Wordpress treats URLs with date based tags only as date archive pages.
3. Given the permalink structure, Wordpress still allows for previewing of posts with present or past publication date (published or drafts) and posts that have publication date set for the future **and** are still drafts. Previewing posts that are scheduled for future publication and are not drafts, is impossible - they will return the 404 error.

Pull GetOption() variable into jQuery dynamically created html
I have a page with the following markup in the site theme footer:
<div id="modalpopup"><div id="inside"></div></div>
I have a variable in the WP db I can retrieve via `GetOption()` which I would like to stuff into that `div#inside` on page load via jQuery.
When I've done AJAX before it's always been upon the user hitting a button to cause a POST, but this is a bit different so I'm kinda stuck.
I need to retrieve that variable from the db, send it to the jQuery function and then have the HTML generated rendered all -before- the page loads.
Ideas? | You would still do this with AJAX, except that instead of firing on some event like a 'click', or 'hover', or `submit`, you would fire the Javascript function on `jQuery(document).ready` instead. That will execute immediately on page load. It doesn't let you execute the code _before_ the page loads as your question states but you can't run Javascript before the page loads. Javascript runs client-side, in the browser. The page has to load in order for that to happen. | stackexchange-wordpress | {

How to deal with the confliction between PHP-Markdown and MathJax?
I use PHP-Markdown plugin in WordPress. In order to show the formula beautifully, I add some code to use MathJax.
Like this:
<script type="text/javascript" src="
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
extensions: ["tex2jax.js"],
jax: ["input/TeX", "output/HTML-CSS"],
tex2jax: {
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
processEscapes: true
},
"HTML-CSS": { availableFonts: ["TeX"] }
});
</script>
But something wrong happens. Once my formula contains at least two underlines, the MathJax doesn't work. Such as `$$P_1, P_2$$`, and the words between the two underlines will be transformed to italic.
The formula will be transformed by PHP-Markdown first, and it can't be transformed by MathJax again.
Could you help me? | I'm not sure this is a real answer, but have you tried PHP-markdown-extra (by the very same Michel Fortin)?
At least for me (using Mark Jaquith's markdown-on-save plugin) your example is not a problem.
But Markdown-extra is not perfect either and I've seen some other quirks with respect to emphasis, e.g. Let $(y_n)_{n\in \omega}$ enumerate ${ x_i: i \in \bigcup_{n\in \omega} A_n} $ will trip it up. | stackexchange-wordpress | {

including image assets in widget
I've written my first simple WP widget-- it all works fine, but I'd like to dress it up a bit, and add an image / logo in the widget display code.
How do I package the widget (which is just a single PHP file) with the image, and where will the image be stored in the WP site (so I can create the img tag link correctly)?
I know I could easily host the image externally and just "hotlink" to it from within my widget, but that seems a little hackish.
Thanks | It sounds like you'll need the `plugins_url()` function which generates the URL for the plugins directory and can handle any alternate configuration (such as if you moved it to the `/mu-plugins/` directory, a personal favorite of mine). The Codex documentation is good, but here's a quick example.
* Let's say you're making this in a plugin that in `/wp-content/plugins/my_awesome_widget/`.
* To make the example slightly more interesting, you store all associated images in `/wp-content/plugins/my_awesome_widget/assets/images/`.
* Your image is called `company_logo.png`.
* In the root plugin directory is your main plugin PHP file which needs to reference the widget.
So to get the image, you'd use a snippet like this:
<?php printf(
'<img src="%1$s" alt="{YOUR COMPANY} logo" />',
plugins_url( '/assets/images/company_logo.png', __FILE__ )
); ?>
If all goes well, that will print out:

Why don't some template tags work when querying information on single.php?
I'm trying to fetch content about the current post into the header.php of my theme (to dynamically insert Facebook OpenGraph Metadata).

wp_head() - list hooked actions with priorities?
I'd like to add something to `wp_head()` but I'm aiming precise location (like after style.css but before rtl.css and before my other custom script). I'm wondering if it's possible to list everything that is attached to `wp_head()` in execution/display order anyhow?
I know that I can pass priority/order parameter to `add_action` but I need to know what number will that be.

It all starts with `10` but somehow rtl.css seems to be always after style.css. Is it `11` maybe? How do I find that out? | While you can practically control order of hooked things by priority, it's not always the right tool for the job.
In case of styles you should be using appropriate `wp_enqueue_style()` function which allows you to easily set up elaborate dependencies which will be automagically processed by WP to produce desired order of styles output.
Unfortunately while there is analogous `wp_enqueue_scripts()` for scripts, you cannot cross-depend scripts and styles like your question indicates.

Removing meta boxes: remove-meta_box() or unset()?

function TEST_remove_dashboard_widgets(){
remove_meta_box( 'dashboard_recent_comments', 'dashboard', 'normal' );

global $wp_meta_boxes;
unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_comments']);
}
add_action('wp_dashboard_setup', 'bmc_remove_dashboard_widgets');
remove_meta_box seems better since it's clearly intended just for that, but I've also seen the unset formulation in several places.
Why would I use one vs. the other? | When in doubt use the API.
Let’s say the structure of `$wp_meta_boxes` will change or go away one day.
`remove_meta_box()` will still work, because the API is a contract between core and developers. Unsetting some keys in a global variable might break.
`unset()` is easier to write when you want to remove a whole group: `unset($wp_meta_boxes['dashboard'])` is clearly simpler than running through each separate box. But shorter code is not always better, so this should not be used in public code.
Note, both methods actually work differently: `unset()` removes an element from the array, while `remove_meta_box()` set the elements value to `FALSE`:
foreach ( array('high', 'core', 'default', 'low') as $priority )
$wp_meta_boxes[$page][$context][$priority][$id] = false;
Other plugins might rely on the existence of that element – and break after you have used `unset()`. | stackexchange-wordpress | {

I've enabled comments in Settings->Discussion and removed the `commentstatusdiv` meta box with `remove_meta_box()`. After that I've figured out that comments is unset when the meta box is disabled.
I am looking for the way to enforce the comments now. | Filter the `'comments_open'` check. It happens inside of the function with the same name, and that function is called in a theme usually like this:
comments_open() and comment_form(
array (
'comment_notes_after' => ''
)
);
This is how the filter works:
add_filter( 'comments_open', 'wpse_98775_comment_check', 10, 2 );
function wpse_98775_comment_check( $open, $post_id )
{
if ( $open )
return $open;
if ( 'my_post_type' === get_post_type( $post_id ) )
return TRUE;
return $open;

Display random posts, but omit the post it is on?
I am trying to have a section under a single post where it displays completely random posts. I got everything working, but every once in a while one of the random posts that get displayed is the actual post that it is on (the single).
Here is my code:
<?php
$args = array( 'numberposts' => 3, 'orderby' => 'rand' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
<?php endforeach; ?>
Is there anyway to not have it ever display the post it is on?
Thank you. | Check to see if you have a post ID (which you should on a single post page but I am not sure if this is in `single.php` or some other template like `index.php`) and add that to the `$args` if you do.

if (is_singular() && isset($post->ID)) {
$args['exclude'] = array($post->ID);
}
$rand_posts = get_posts( $args );

Print out one of 2 post category
I've been trying for quite a few hours to get something to print out in loop: post has 2 categories, one of them is `prace` (slug) and I need the other one printed. If it isn't too much to ask.

Custom Role does not have access to dashboard
I was just adding a custom role by using the add_role() function. Here is the code below:
add_role('user', 'User', array('read'));
I figured this would give the same level of access as the subscribers role. Technically I want them to be the same but I don't want to use the subscribers as a role for certain users because there will be different access between the two.
However, although, from what I read on the wordpress codex site, the subscribers has only one capability and that is to 'read' it has access to the dashboard and can edit their own profile. My custom role cannot. I get the following message when going to the admin panel.
_You do not have sufficient permissions to access this page._
Why is that? Hoe do get the right permissions to do this?
Thanks, Joe | You have to give the capability a true or false, like this:
`add_role('user', 'User', array( 'read' => true ));`
To fix it, first remove the role and than re-add it again.
remove_role('user');

Post Terms As Class Name For Full Calendar Events
I have implemented Full Calendar via json with my Wordpress custom post types.

{
echo $terms[0]->name;
} }
Thanks for any advice | You are using `get_single_term` in a way that would require it to return a value...
$term = get_single_term($post->ID, 'course_locations');

function get_single_term($post_id, $taxonomy) {
$terms = wp_get_object_terms($post_id, $taxonomy);

{
return $terms[0]->name;

I noticed a couple of other things not directly related to the question but worth mentioning.
1. You really should be using the AJAX API. `include`ing `wp-load.php` like that is a kind of hack, in my opinion, that is no longer necessary. It is also prone to error. Imagine if someone were to move one or more of the content directories.

Why do you need an unlikely integer in paginating?
The `paginate_links` Codex function reference has some sample code that's being reposted all over the net.
It has a section that uses a variable called `$big = 999999999; // need an unlikely integer`:
echo paginate_links( array(
'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
'format' => '?paged=%#%',
'current' => max( 1, get_query_var('paged') ),
'total' => $wp_query->max_num_pages
) );
And is used in `str_replace` in the `echo paginate_links` function.
Is this some form of encapsulation? | Note the `get_pagenum_link( $big )`: This will create an URL ( _not_ a link) based on the number provided in the first parameter.
That function is used to get the basic pattern for the URL, and the high integer is used here, because:
1. You must provide an integer as argument.
2. The resulting URL is filtered with `apply_filters('get_pagenum_link', $result)` and might be changed by plugins. This risk is slightly higher for numbers _matching existing pages,_ for example when a plugin implements separate titles for sub-pages.
So this is just a … dirty convention, a signal to other plugins: Don’t change that please! I think `PHP_INT_MAX` would have been better, but still ugly. And I wonder how many plugin developers _know_ that.
The number is then replaced with the placeholder needed in `paginate_links()`.
What you see here is an **incomplete API**. Try to learn something from this example – do not release incomplete APIs, or your docs will look embarrassing. :) | stackexchange-wordpress | {

List the categories under custom taxonomy

Cannot select certain authors for posts after import
I just consolidated a couple standalone WordPress installs into one Multi-site install. After importing posts into each site accordingly, I am unable to edit a post or page, and select a different user.

Walk over the post IDs, get the tags of each post. Add the tags to a result array (`$tag_all`).

Is a *.wordpress.com blog easy to migrate?
As a student software developer who is about to graduate, I find it is time to start my own blog. I've been told it is important to make a name for yourself, to stand out from the rest. Therefore I decided to make a Wordpress website.

Output posts with same name as tags?

WP_Query meta_query by array key
I have a custom post type with its meta in an array. What I need to do is query based on the value of a key in that meta array.
$args = array(
'post_type' => 'my-cpt',
'posts_per_page' => -1,
'orderby' => 'meta_value', // Sort by this value
'meta_key' => 'my_meta_array', // Sort by this meta key
'meta_query' => array(
array(
'key' => 'key here', // WHAT GOES HERE?
'value' => array( 'meta-value' ),
)
)
);
$query = new WP_Query( $args );
What goes in the meta_query key, if my key is my_meta_array[key]?
FYI: the keys are indexed by my_meta_array[key], stored in the db via update_post_meta( $post_id, 'river_helpers', 'my_meta_array' ), and retrieved via get_post_meta( $post->ID, 'my_meta_array', true ); | You can't do that. When you save postmeta (or any other meta, for that matter), WordPress runs it through `maybe_serialize` which turns objects and arrays into serialized data. When it gets pulled back out, it is run through `maybe_unserialize`.
Serialized data looks something like this:
a:1:{s:3:"one";s:3:"two";}
In other words, what get's stored cannot be queried in the way you want. The best you could do is a `LIKE` query, which will be unreliable at best and less performant. Just use `LIKE` as the `compare` argument of your meta query.
Your best bet: rethink how you store meta and move whatever `key` is to its own entry. Meta tables in WordPress are key value stores, it's not unreasonable to store multiple meta values per post type or plugin. | stackexchange-wordpress | {

Display posts of the last 7 days
I'm trying to display the 5 best rated posts of the last week (7 days) on my website, however I can't seem to figure out how to display them.
Here's what I've achieved so far but it doesn't seem to work:
<?php $slider_query = new WP_Query('posts_per_page=5&cat=3&orderby=highest_rated&order=desc'); ?>
<?php
$mylimit = 7 * 86400; //days * seconds per day
while ($slider_query->have_posts()) : $slider_query->the_post();
$post_age = date('U') - get_post_time('U');
if ($post_age < $mylimit) {
?>
//The Post
<?php } ?>
<?php endwhile;?> | In addition to birgire's solution, as of WordPress 3.7, you can use Date parameters.
Your arguments would look like this to filter posts from the last 7 days:
$args = array(
'post_type' => 'post',
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'DESC',
// Using the date_query to filter posts from last week

Create post thumbnails from images stored outside of uploads directory
I am redoing some of my older blogs and I noticed with the new themes most of them take advantage of featured images which is fine. The problem is a lot of my older posts that was never set either because I did not use it or because it didn't exist.
Now I know of the featured thumbnail plugin the regenerates your posts and it grabs the images from your post and makes a thumbnail which is great and that works, but I have some posts where the images were not stored in the uploads folder where the plugin seems to be looking and those posts fail.
Any thoughts on how I can get these featured images without going through every single post manually? | You need to first download those external images then you can attach and set them as the post thumbnail.
To download and attach you can use the `media_handle_sideload()` function.
I wrote a plugin that will search through all your posts and pages and download and attach any external image into the media library. It also has the option of setting the first image as the featured image.

get_term_link not working
I am trying to use the below code snippet to display an image and then wrap it in a link to a specific term archive page. In this case, I have a custom taxonomy (Series) with a few different terms. The variable $series outputs the Term Object, therefore I want to use the get_term_link function to get the URL to the terms archive page.
The documentation for get_term_link (< says that I should simply be able to provide the term object and it will work, but it's not. I'm getting a partial-page load, meaning the code is breaking when it reaches this function.
Any help is appreciated!
$imageid = get_sub_field('series_banner', 'options');
$image = wp_get_attachment_image( $imageid, 'home-series-banner');
$series = get_sub_field('series_link', 'options'); //Returns the term object ?>
<a href="<?php echo get_term_link($series); ?>"><?php echo $image; ?></a> | That field can return multiple term objects depending on how you've got it configured, so I'll guess that `$series` in this case is an array containing a single element, which contains your term object. Try inspecting the contents of series:
print_r( $series );
You'll probably see something like:
Array
(
[0] => stdClass Object
(
[term_id] => 1
[name] => test
[slug] => test
[term_group] => 0
[term_taxonomy_id] => 1
[taxonomy] => category
[description] =>
[parent] => 0
[count] => 1
)
)

Character \ appearing before ' after saving a settings page
It's a strange issue and I've seen it happen with plugins, however I don't know how to fix it. Maybe just a PHP issue?

I'm not sure what code would be helpful to look at for this. | It's a PHP issue. The character `'` is being escaped so that it can be safely in various places, not least of which is the database. That's why your `'` look like `\'`.

Plugin fatal error
I'm trying to activate a plugin I made on a network site. I'm getting an error:
Plugin could not be activated because it triggered a fatal error.
I have the debug mode on and it outputs all errors into a debug.log, however nothing is given for this error.
Is there another way to see what the error may be?
The plugin registers a CPT with taxonomy. It was recently deactivated to test a few changes I made. Upon the reactivation it is failing.

I had to export my post and taxonomy tables from the database, then delete everything, before I was able to activate the plugin.
After the plugin was active, I was able to import the posts and taxonomy terms back into their respective tables. | stackexchange-wordpress | {

Add a custom stylesheet for BlackBerry

Wordpress User Name Limitations
I need to know what the wp specifications for the usernames are. Like allowed minimum and maximum length, are special characters like ü,ö,ä,ß accepted,..?
Unfortunately I couldn't find any insight on this in the interweb. Do you have any? | I think the answer is in the source.
$username = wp_strip_all_tags( $username );
$username = remove_accents( $username );
// Kill octets
$username = preg_replace( '|%([a-fA-F0-9][a-fA-F0-9])|', '', $username );
$username = preg_replace( '/&.+?;/', '', $username ); // Kill entities
// If strict, reduce to ASCII for max portability.
if ( $strict )
$username = preg_replace( '|[^a-z0-9 _.\-@]|i', '', $username );
So, the code strips tags, octets, and html entities. And it replaces accented characters with unaccented ones via the `remove_accents` function, which is fairly lengthy. Other characters get through unless `$strict` is `true` (default is `false`), in which case only ASCII characters are allowed.
The maximum login name length would be the database limit for the user_login column\-- 60 characters. The minimum, as best I can tell, is 1. | stackexchange-wordpress | {

Use oEmbed in List Items
I'm aware that WordPress has oEmbed functionality. But the content to be embedded has to be on it's own line like so:
Lorem Ipsum
More Lorem Ipsum
Unfortunately, my markup looks like this so oEmbed doesn't work and I have to use a plugin.
<ul>
<li>
<li>
</ul>
Is there anyway I can get oEmbed to work without this plugin? A line or two in functions.php would be better than this plugin. | Just use the `[embed]` shortcode around your items.

What does setup_postdata ($post ) do?
The codex defines it as 'Set up global post data. Helps to format custom query results for using Template tags.' I don't really understand this.
Here is a code example :
global $post;
$args = array( 'numberposts' => -1);
$posts = get_posts($args);
foreach( $posts as $post) : setup_postdata($post);
echo $post->ID;
endforeach;
Please can you explain? | Template tag functions rely on global variables to access the post being processed and retrieve data from it or related to it.
The main variable among these is `$post`, which holds the post object itself.
In your example it's not explicit, but what is happening is that your loop assigns data to `$post`. If its name wasn't `$post`, you would need to name it explicitly (`global $post; $post = $some_other_post;`).
However, there are a bunch of other globals and the purpose of `setup_postdata()` is to fill them with data. If you look at the source, these are:
global $id, $authordata, $currentday, $currentmonth, $page, $pages, $multipage, $more, $numpages;
Note that in most cases you should be calling `wp_reset_postdata()` afterwards to return globals to their original state. | stackexchange-wordpress | {

What does extract( shortcode_atts( array( do?
The codex says
> _**`shortcode_atts()`** combines user shortcode attributes with known attributes and fills in defaults when needed. The result will contain every key from the known attributes, merged with values from shortcode attributes._
It doesn't make much sense to me (I'm a newbie).
Here is an example:
function wps_trend($atts) {
extract( shortcode_atts( array(
'w' => '500',
'h' => '330',
'q' => '',
'geo' => 'US',
), $atts));
$h = (int) $h;
$w = (int) $w;
$q = esc_attr($geo);
ob_start();
Please can you explain? | `shortcode_atts()` works like `array_merge()`: It merges the second list of arguments into the first one. The difference is: It merges only keys present in the first argument (`$default`).
`extract()` then takes the array keys, sets these as variable names and their values as variable values. `'w' => '500'` in your example becomes `$w = '500'`.
Do not use `extract()`. This very bad code style. Its usage was deprecated even in core, and that means something … :)
Your example should be written as:
$args = shortcode_atts(
array(
'w' => '500',
'h' => '330',
'q' => '',
'geo' => 'US',
),
$atts
);
$w = (int) $args['w'];
$h = (int) $args['h'];

What does get_current_screen() do?
Codex says ' This function returns an object that includes the screen’s ID, base, post type, and taxonomy, among other data points' . What does it mean by 'screen'?
Coding example:
function change_default_title( $title ) {
$screen = get_current_screen();
if ( 'POST_TYPE' == $screen->post_type ) {
$title = 'Enter Invoice Title';
}
return $title;
} | If you look at the source of `get_current_screen()` it's a really small function the merely gives you value of `$current_screen` global variable. There is matching `set_current_screen()` that fills that variable.
What the variable actually contains is instance of `WP_Screen` class. There is plenty going on in that class, but in a nutshell it keeps track of context for admin page you are currently seeing and implements functionality, shared between admin pages. | stackexchange-wordpress | {

How to make a website like the ones in theme demos?
I don't understand, in Joomla there was a quickstart package that came with templates to show the template's power with data. So our site would be like the one we see in the demos.

Advanced custom field - gallery - display one random image
I created a gallery with the "gallery add-on" of "advanced custom field" plugin.

$rand = array_rand($gallery, 1);

<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />

<?php
$gallery = get_field('gallery_home');

Pull Instagram images into an existing loop?

Is that possible (with or without a plugin)?

How to set hierarchical terms to a post using wp_set_object_terms
I have a hierarchical custom taxonomy called "locations". The parent categories are country names, the child categories are the territories under the country.
How can i attach these terms to a post programatically?
$country = 'Egypt';
$territory = 'Hurghada';
So, if the Egypt category doesn't exist, i need to create it, and i need to attach the $territory in a subcategory under Egypt.
This is where i am so far:
$post_id = 10;
$country_term_id = term_exists( $country, 'locations' );
if ($country_term_id !== 0 && $country_term_id !== null) {
wp_set_post_terms($id, $country,'locations');
} else {
//I guess this is where i need to set the territory?
} | Since `wp_set_post_terms()` does not accept hierarchy for it, you will first have to check if terms exist already, create them using `wp_insert_term()` if not and only then assign to post.

How can I highlight specific pieces of text within a blog post?

I have found a few methods related to syntax / code highlighting. I am not trying to highlight code but merely text within a blog post. Preferably I would like a simple method that provides a UI button within the editor itself as some users that post articles are not technically savvy and may have issues with short codes. I am currently running Wordpress version 3.5.1. | While I rarely recommend plugins, the CKEditor plugin will do highlighting of selected text. That sounds like exactly what you want.

Wordpress <!--more--> adding a <br> to my anchor for Read More
When creating a post within my wordpress site (using the editor) I want to add the short code, or even use the link at the top of the editor to do so.
The end result is (it does create the excerpt and add the "Read more" link) but that link is broken and the editor has seemingly inserted a
tag within my anchor breaking the link.
`<a href=" /> /a-test-post/" class="more-link">Read more »</a>`
Anyone have an idea as to why this would be happening? | Because of the way that `wpautop` works, I would expect that if you had a newline, or or maybe a space in your URL. I can't seem to get a space or newline to save from the admin interface, but it is trivial to insert by editing the `WP_HOME` and `WP_SITEURL` constants into `wp-config.php`... but that causes every page to 404 or worse.
There must be something happening when the link is generated-- possibly something hooked to `excerpt_more` or `the_content_more_link`. It is also possible that your theme is parsing the more link itself and bypassing the normal channels.
Without more information, that is all I have.

How to Put Custom Taxanomy Meta Box in Main Column
WordPress added the Custom Taxonomy Meta box at sidebar, Is there any way which we can relocate it in the main column , Under Edit box?
Thansk | Unfortunately WP is hardcoded to generate taxonomy metaboxes in that `side` location.
It is tad fragile, but possible to throw generated data around from one location to another:
add_action( 'add_meta_boxes', 'move_taxonomy_metabox' );
function move_taxonomy_metabox() {
global $wp_meta_boxes;
$taxonomy = 'test';
$metabox_key = 'tagsdiv-' . $taxonomy; // or $taxonomy . 'div' if hierarhical
if ( isset( $wp_meta_boxes['post']['side']['core'][$metabox_key] ) ) {
$metabox = $wp_meta_boxes['post']['side']['core'][$metabox_key];
unset( $wp_meta_boxes['post']['side']['core'][$metabox_key] );
$wp_meta_boxes['post']['normal']['core'][$metabox_key] = $metabox;
}
}
More proper way might be to just nuke generated metabox and completely redo registration. | stackexchange-wordpress | {

Unable to get WordPress auto update working on Ubuntu 12.04
I'm getting a tiny bit fed up with having to `chown 777` my entire WordPress folder in order to auto update a plugin, and then set the permissions back again. I've looked around for fixes now, but no fix I try seems to work.
I'm on an Amazon EC2 instance running Ubuntu 12.04. So, the Apache2 installation is stock standard out of the box, runs as the www-data user.
I've set my owner:groups to my entire project to ubuntu:www-data, and the permissions through the bank is set to `***rwxrwx--r**`, or `774`, meaning that either the ubuntu user, or the www-data group will have full read/write access to the file structure.
Whenever I try to update WordPress however, it asks me for FTP/SFTP details, so in order to get that going away, I need to run `chown -R 777` ... on the entire project folder.
That's annoying, and I've got no clue as to why this is happening. How can WordPress execute something other than the Apache2 user? | Found a fix. Simply add the following snippet to functions.php for your theme:

What you want is `get_post_meta` or `get_post_custom`. Those will return arrays which you will have to loop over and format yourself. `the_meta` uses `get_post_custom`. You can use its code as a template for your own code if you want. | stackexchange-wordpress | {

Thanks for your help
Gary | I would actually handle this with CSS. In your `style.css` file add something like this:
.page-title h1 {
text-indent: -9999px;
background: url(images/your_logo.png) 10px 10px no-repeat;
height: 100%;
}
You'll then make sure that your logo is added to your theme's `images` folder. Also, adjust the size of the image accordingly, or you can also adjust the size of the container.
