Converting HTML5 to XHTML
What do I need to ponder if I want to convert Twenty Eleven theme to XHTML? Is it just the matter of replacing the HTML5 for divs? | Probably the easiest way to do it is to set the doctype, etc and then use the w3c xhtml validator and just go through one by one and pick off the errors...but that will take A LOT of time, I strongly recommend you leave it as is. | stackexchange-wordpress | {

Convert attachment ID into url?
I'm using the plugin advanced custom fields to create custom fields to create a relationship between two pages.
The code below is looking at the relationship field and grabbing the page title and company logo of the linked page.
The only problem is that instead of outputting the image url (so it displays the image), it's outputting the attachment ID. How can I convert the attachment ID into a url so the image displays?
<?php foreach(get_field('connections') as $relationship): ?>
<img src="<?php echo get_post_meta($relationship->ID, 'company_logo', true ); ?>" height="57" width="250" />
<a href="<?php echo get_permalink($relationship->ID); ?>"><?php echo get_the_title($relationship->ID) ?></a>
<br />
<?php endforeach; ?> | You need the function wp_get_attachment_image_src() see <
In your code it would be something like:
<?php foreach(get_field('connections') as $relationship): ?>
<?php $img = wp_get_attachment_image_src( get_post_meta($relationship->ID, 'company_logo', true ), 'thumbnail' ); ?>
<img src="<?php echo $img[0]; ?>" width="<?php echo $image_attributes[1]; ?>" height="<?php echo $image_attributes[2]; ?>" />
<a href="<?php echo get_permalink($relationship->ID); ?>"><?php echo get_the_title($relationship->ID) ?></a>

How to add super admin to all sites

My group of super admins needs access to all sites. | Super admins do have access to all sites, but they don't show up in "My Sites" by default, which I imagine is where you're looking. They'll want to go to the network admin (/wp-admin/network/, then go to all sites from there, then find the site they want to edit and click "Dashboard" (which appears on hover).

How to prevent a page from being linked in the menu/crossbar

How to redirect a link to a new link?
I am about to change the slug for my page's permalink. Since I dont want to loose the traffic, i would like to redirect the visitors to the new more SEo friendly link.
Can I achieve this with the mod_rewrite? (I use Apache on Ubuntu)
Or any other easier alternative? (I prefer not using any plugin if possible)
Many Thanks, | Go with the easiest alternative of all: _do nothing_.
No, really: WordPress itself handles redirects for renamed Post Titles.
### Edit
Apparently, the retention of `_wp_old_slug` only happens for _non-hierarchical_ objects.
So, since Pages are hierarchical, they don't get to enjoy the auto-magic slug redirection.
Therefore, for static Pages or other hierarchical post objects, I would recommend using a 301 Redirect Plugin. There are several to choose from. | stackexchange-wordpress | {

How to prevent URL-modification when page title contains digits only?
When I create a page whose title contains only digits - wordpress adds '-2' to the url, like it does in cases, where there is a page with the same name already existing. However this is not the case here.
Example: If I create a page titled `909303`, the url will be: `../909303-2/`
I want it to be `../909303/`. How do I do that conveniently? | well.. it is not exactly the case, but in a way, it is . every page has actually "2" names , one is the name you give and one is the ID, which is the number. If you will give a "name" which is a "number" - it might override another entity (Can be a post, page , attachment, or even a draft) with the same ID. that would result in multiple errors and 404 , depending on your permalink structure.
SO , it is not such a good idea to do that, but if you really want to go with it first try to change your permalink structure and if that does not work, you will need to hook the sanitize_title() - but I will still advise to avoid such a practice.

Is it possible to have one page with multiple items, or 2 blogs on a site?
I have a Page on my site that I use as a Blog.
And then there's another page that I'd like to add a few different posts to. It's not really a blog, it's a list of projects, and each one will have about 300 words of description.
I'd like users to be able to pick which project they want to view. So this could work as either a blog, or as a drop-down menu from the menu item 'other projects', or maybe in another way.
\-- Since I already have a blog on the site, is it possible to add another blog under another menu item?
\-- Or is there another way to accomplish the objective, such as making 'other projects' a drop-down menu?
The current blog is here: <
And the page I'd like to list projects on is here: < | It's absolutely possible on the same WordPress install.
How I do it, is I generally reserve the 'posts' sections for the site's news, and make a Custom Post Type for other things, such as your projects list.
Have a look at the codex for custom post types, and the template hierarchy
To separate the blog posts from your projects custom post type, simple add something like this is the appropriate template file:
query_posts( 'post_type=projects' ); // For projects
Or
query_posts( 'post_type=post' ); // For posts
query_posts works if you're using the main query.
* * *
Another solution, if you have no extra data to keep about projects, is to simply store your projects in 'posts' as well, and associate a category to them.
query_posts( 'post_type=post&cat=5' ); //EX if category id 5 = projects category | stackexchange-wordpress | {

How do I install more than one WordPress blog on EC2?
I created an EC2 instance and installed WordPress inside `/var/www/html/blog/`. I'm running Amazon Linux with Apache.
Assuming I want to create another blog. Do I create another directory and install WP as per the first attempt? Or can I run two blogs from the same installation? | Unless EC2 is much different than other servers, you should be able to install another WordPress installation under another directory.
For instance, you could have `/var/www/html/blog/` with WordPress installed and `/var/www/html/blog/wordpress` with another WordPress install.
You can either use a separate database or use the same one as the other install, but you would need a unique table prefix set in the wp-config.php.

Change div background acording to the selected category
I'm coding a graphic menu that consist in five divs with a background each. On mouseover the background changes and the child div disappears. On click, each one works like a link to the correspondent category. I want to apply some changes to the clicked div, so I was wonder if there is some function in wordpress to get the selected category. So I can check for It and in function of wich category is selected apply the changes to the correspondent div.
Thanks in advance. | If you use `wp_list_categories` (see Codex), it automatically adds the classes `cat-item`,`cat-item-{ID}` and (to the current category being viewed) `current-cat`. (It also adds `current-cat-parent` to the parent of the current category).
This should be enough to style any particular category a certain way, and style the current category a particlar way.
However, you can obtain the current category being viewed by, in your category template file, using:
$term = get_queried_object();
The current category's slug is given by `$term->slug`. This would allow you to add a certain styling to the current category (the exact details of how to do that would depend on how you were displaying the category links). | stackexchange-wordpress | {

How to convert hits from Top 10 plugin to WordPress Popular Posts?
How can I import/convert hits from the plugin top 10 to wordpress popular posts plugin? | # Short Answer
You don't.
# Long Answer
These two plugins are fundamentally different. Popular Posts stores views in a custom field with each post. Top 10 creates a new table in the database and stores views there.
So you'll need to look for the `wp_top-ten` table in your database. It should have these fields:
* `postnumber`
* `cntaccess`

How to hook into wordpress admin upload iframe?
I have written a plugin which lets the user upload file attachments for using WordPress as a download site.
So I have added a meta box which shows the user the files he has uploaded for every post. Everything is working fine until I wanted to make it so that if a user uploads file using the built-in upload manager and then closes the ThickBox a function of mine is invoked to update that meta box for new files.
In simple words, I want to be able to listen on the ThickBox close event. That's it. | When the thickbox gets closed it triggers 'tb_unload' (in earlier WordPress version it was just 'unload' (not sure though) )

$(window).bind('tb_unload', function() {
//do stuff

possible to combine sites that have lots of content, into multisite?
i run 3 wordpress sites.
they are each on different installations.
i don't really want to combine them right now because i'm not very proficient technically, with wordpress, but i might want to combine them at a later date, to make it easier to administer.
but i want to check in case it's better to set it up now, because i'm just setting one wordpress site up -- maybe it's better to do this now.
so my question is: at a later date, when i have 3 sites running, each with lots of content on, can i combine them at that time?
or does setting up multisite involve starting things from scratch? | > at a later date, when i have 3 sites running, each with lots of content on, can i combine them at that time?
Yes, you can. I've found the easiest way to do so is to use the Export/Import feature, but it really depends on the site, and sometimes you have to get creative. Assuming these will be easy, what you would do is setup a multisite install, create new sites within this for each of your 3 solo sites, export XML files from your solo sites, then import those XML files respectively into the new sites in your Multisite network.

Recent posts script mess up blog posts

Using Ajax call in jQuery doesn't work in widget
So I'm in the midst of creating a new conversion widget and I'm having some trouble getting the Ajax call to work in my widget. (works perfectly outside of WordPress).
The problem at the moment is that it outputs the whole homepage in the #results div rather than just the results figure: | If your AJAX Url is conversion.php it will most likely point to yourdomain.com/conversion.php. Is your file in that location?
Looks like not, and I guess you don't have a 404.php, and in that case your request gets directed to your index.php, that's why you get the contents of your homepage.
If your file is in your theme folder, you would have to change the URL to wp-content/themes/yourtheme/conversion.php

Solution for Wordpress URL structure changes and 301 redirects?
After a major site review, we've created a new link and category structure to better accommodate URLs and content for the long-term. While we roll out the change, we need to avoid broken links and SEO issues because our category structure is changing.

Beta Versioning of Plugins
When I'm writing a fix to some bugs, I often increment the version and send it to the bug finder to see if my fix works. If I have `1.2.5` and I want to create a beta that will become redundant once I commit my code, should I use `1.2.5-beta` or `1.2.6-beta`? My concern is that `1.2.6` < `1.2.6-beta` so that the string comparison may favour the beta and the bug finder would not get a notification of the stable version being released.
EDIT:
If the string is compared absolutely without taking into account the release type, you could use `1.2.5-fix` and then `1.2.6`. The problem is also outlined at < | If your current plugin version is `1.2.5`, and you have a beta version for the next version, it should be called `1.2.6-beta`. Your user can install it, and when the real `1.2.6` version is released on the repository, WordPress will notify the user on the Plugins page and let him update.
WordPress uses a PHP function called `version_compare` to compare version numbers for this purpose. When comparing version numbers, WordPress will recognize them like this:
`1.2.5` < `1.2.6-beta` < `1.2.6`
I've tested this out with a plugin of my own in the repository, currently at version `0.45.11`. I changed the version number of the plugin on my own site to `0.45.11-beta`, and WordPress let me update to `0.45.11` from the Plugins admin page. | stackexchange-wordpress | {

Is there a wordpress plugin enabling an autocomplete search box, then jump to page?
I have very little experience with WordPress. I am exploring it as a potential solution for our needs.
I would like to implement an autocomplete search box (a bit like jQuery's) where users could type, say, the name of an ingredient and jump automatically to that ingredient's page. We would fill the possible values of the search box ourselves.
Is there such a plugin for WordPress or should implement this myself via Javascript? If I need to implement this myself, are there any tips/code examples available? | You could use the autocompleter plugin. It does exactly what you describe: it autocompletes half-typed tags and categories.

PNG with transparent background turns black when uploaded and resized
Steps to reproduce:
1. Create a PNG-8 with a transparent background.
2. Upload to WordPress 3.3.1.
3. View original PNG in any browser, Chrome, Firefox, IE, etc. Notice that it retains transparency as it should.
4. View a resized version of that PNG in any browser. Observe that the transparent portions of the PNG are now black.
Examples:
* Original uploaded image: <
* Resized version of the uploaded image: <
This occurs even with a clean install of WordPress 3.3.1 with no plugins activated. Any ideas on what might be causing this bug?

Show add_meta_box by selecting a specific category

How to secure WordPress XMLRPC?
XMLRPC is great for remote publishing to WordPress, but there has been many security issues attributed to it. How do it make it more secure? More specifically, only user from the intranet will be publishing through XMLRPC. WP is currently running on Lighttpd and php5.3. | XMLRPC is as secure as the rest of WordPress. All of the requests need to be authenticated with username and password credentials that exist on your site already. That means, if someone has a login for your site, they can use the XMLRPC interface (if it's turned on). But anonymous users can't get in.
The only potential security vulnerability you might face with XMLRPC is that of a man in the middle attack. But you face this same risk with the regular WordPress admin, so it's not unique to XMLRPC.
The _best_ way to prevent this kind of an issue is to enable SSL security on your site. You'll need an SSL certificate, and then you need to access you XMLRPC endpoint via ` rather than ` This will encrypt your requests and prevent anyone from intercepting them and stealing your credentials.
You should also enable SSL security on login for your regular site because it, too, faces the same risks. | stackexchange-wordpress | {

Blog shows up without Theme/CSS styles
I installed Wordpress to my own domain and it was working just fine. I then, downloaded a new Wordpress theme and uploaded it into the wp-content/themes/ folder directory.

How to edit it to limit number of posts and specific taxonomy name of this custom post type. | I prefer using using the array form...

array(
'taxonomy'=>'my-custom-tax', //Your custom taxonomy name

'field'=>'slug',//or you could select by ID
'terms'=>array('my-term-slug')//Get posts with this term (or ID if above is ID)

add_rewrite_rule('foobar/page/([0-9]+)?$','index.php?is_foobar_page=1&paged=$matches[1]','top');

You can look for the function login_with_ajax() in your themes header.php and remove it, if it's there.
If an undefined function is called you get a fatal error and the script will stop. So it only displays until the function, in your case the end of your header. | stackexchange-wordpress | {

Compatibility with RTL installations
I want develop a plugin that add boxes and menus in WordPress backed.
What I have to keep in mind to make it **compatible with WordPress RTL** installations?
Any idea or suggestion will be appreciated.
Thanks | You can use `is_rtl()` to check if the user is setup for RTL or not, then you would just need to register and enqueue the RTL styles instead of the LTR styles. | stackexchange-wordpress | {

add_filter() doesn't work in loop
I'm trying to order the posts in the home page by modified date, and I put this code in the functions.php of my active child theme:
function orderby_last_modified() {
return 'post_modified DESC';
}
If I add the filter in the same functions.php file it works:
add_filter('posts_orderby', 'orderby_last_modified');
But I only want the filter in the home page loop, when I change that line to the home page it just dont work.
<?php
add_filter('posts_orderby', 'orderby_last_modified');
if(have_posts()):
while(have_posts()) atom()->template('teaser');
remove_filter('posts_orderby', 'orderby_last_modified');
?> | It doesn't work in your template because the query has already happened before the template is loaded. If you want to add your filter only under certain conditions, you need to hook an earlier action, like pre_get_posts, and check if the query is for the home page:
function add_my_orderby_filter( $query ) {
if ( $query->is_home ) {
add_filter('posts_orderby', 'orderby_last_modified');
}
}
add_action( 'pre_get_posts', 'add_my_orderby_filter' );
This would go in your `functions.php` along with your `orderby_last_modified` function.
See the WordPress Action Reference for the order actions are executed in a request. | stackexchange-wordpress | {

Nice way to print_r arrays
So you know how Drupal has functions in modules like Devel that allow you to output arrays in a nice format like `dsm($array)` or `krumo($array)`... Does WordPress have an equivalent or a nice way of displaying `print_r($array)`? | I created a Kint plugin that works really well. I also integrates with the Debug Bar plugin. You can download it at: <
There are a few functions to help you out with WordPress specific globals:
* `dump_wp_query()`
* `dump_wp()`
* `dump_post()`
For printing arrays in a styled, collapsible format you would do the following.
$foo_bar = array(
'foo' => 'bar',
'bar' => 'oof',
'rab' => 'foo'
);
d($foo_bar); //Styled
s($foo_bar); //Un-styled | stackexchange-wordpress | {

Post data returning null
I'm writing code from within a plugin and I'm attempting to create a two-part registration form. I'm using POST to determine if the first part of the form was submitted or not. Unfortunately, though, the POST data is not coming through. Here is what my form looks like:
<form action="<?php echo $_SERVER['REQUEST_URI'] ?>" method="post">
<input type="submit" name="user_info_form" id="user_info_form" />
</form>
This should POST back to the same page, in theory. I then use the below code to read the POST data.
if(isset($_POST['user_info_form']))
{
echo "found data";
}
else
{
echo "nothing found";
}
Unfortunately, "nothing found" is being outputted following a form submission.
Is there any reason for this that has to do with WordPress? I've been at this for hours now so any help is _very_ much appreciated! | I found my own answer on this one (just now). The stupid plugin had javascript at the bottom of the page disabling all submit buttons from working - what a joke, sorry everyone. | stackexchange-wordpress | {

How can I show the subcategories content on the parent category page?
I have a WordPress website that has a category with two subcategories.
Now, how is it possible to show the content (the subcategories items/content) on the parent category? | One possibility:
<?php
$sub_cats = get_categories('parent=' . get_query_var('cat'));
if( $sub_cats ) :
foreach( $sub_cats as $sub_cat ) :
$sub_query = new WP_Query( array(
'category__in' => array( $sub_cat->term_id ),
'posts_per_page' => -1)
);
if ( $sub_query->have_posts() ) :
while( $sub_query->have_posts() ) : $sub_query->the_post();
//your output//
endwhile;
endif;
endforeach;
endif;

Split Testing with W3 Cache Enabled?
I'm trying to do some simple split testing on a category page, but W3 Cache is causing some issues.
To do the split testing, I randomly select a layout (either grid or horizontal), then I store it in a $_SESSION variable so that the page is the same for that user while they're on the site.
Then on the category-slug.php page, I just do an if statement to determine what layout to display based on the value in the $_SESSION variable.
It is all working fine, except W3 Cache is caching the page. So the $_SESSION will have a grid layout value, but a horizontal layout will actually be displayed. Obviously this skews my data.
I'd rather not disable W3 Cache since it helps reduce our page load time. Anyone have any ideas? | I ended up just putting variables to denote the layout in the conversion link.
For example, if the layout is a grid, the url is <
It doesn't consistently let me switch layouts between users, but at least the data isn't being skewed by a $_SESSION variable reporting something differently than what is being seen by the user. | stackexchange-wordpress | {

implementing a centralized content "show-do-not-show" toggle?
I have many custom templates for different post types, and I am manually inserting a social share bar inside the 'entry-meta' footer in each of those templates. I need a simple centralized way to disable the social share bar without hacking into the plugin.
Basically I have this setup so far:
In **functions.php** :
`update_option( 'show_social_bar', 'true' );`
In my templates I have this check:
if( get_option( 'show_social_bar' ) === 'true' ) {
// show my social share links
}
If I need to turn the bar off, I just set the option to 'false' in **functions.php**. This somehow seems inefficient. Is there a more sensible way? | It's a bad practice to update an option on every page load. You should use a constant instead.
define('SHOW_SOCIAL_BAR', true); //functions.php
if(SHOW_SOCIAL_BAR){
//Do Something

Minimal WordPress Functionality on Existing Website
I have a client that wants the ability to remove or add a special offer from the front page of her website.
I thought of creating a custom loop using a featured image etc, which would display the latest special offer.
Her site is a PHP site right now without any WP functionality.
What is the minimum installation that would allow me to display this loop. Instead of creating a theme and template I just want to use the existing page.
Thanks. | You can require the wp-load.php file in the existing page...
<?php require('wp-load.php') ?>
This will basically load the WordPress installation and allow you to access each of the functions (and the loop) as you normally would. | stackexchange-wordpress | {

Main Sidebar Dispappeared - What could possibly cause this?
I used to have the drag & drop Widgets on Main Sidebar working but for some reason it no longer works. That is, whatever I place there (on the back-end) is no longer visible on the front-end.
In my attempts to troubleshoot this, I uninstalled completely the only 2 plugins I had:
1. "Contact Form With Captcha"
2. "WP fade in text news"
But that didn't help.
I also switched back to the `twentyeleven` theme (from a child theme containing `style.css` only) but that didn't help either.
I also compared the content of the entire directory tree with pristine copy of the WordPress 3.3.1 ZIP package and found no differences. Does this point to some problem in some settings stored in the database?
Lastly, I tried the 3 different `Default Layout` settings in `Appearance > Theme Options`, just in case. That didn't help either.
What could possibly make the sidebar disappear? | After much search I found an explanation to the mystery: With the new `Twenty Eleven` theme (from WordPress 3.2 and up), the sidebar is gone in the **single post page**. | stackexchange-wordpress | {
