Yoast SEO plugin - Sitemap links greyed out & page priority
I have a sitemap - <
Why are some of the links within the sitemap greyed out? Also is it worth changing the priority of some of the pages to achieve better seo results? | Grey links are how it styles visited ones.
Priority is mostly for indexing purposes (as is rest of sitemap), I highly doubt is has any impact on search engine ranking. | stackexchange-wordpress | {

Changes in code only show after changing theme
I have a weird problem that happens only in one of my Wordpress sites (which is on a development server with many other wordpress sites that don't have this problem):
When I make changes in code - be it php, css or html - I can't just go to my site and refresh the pages for the changes to show up. I have to go to the themes page in the admin area, change to a different theme, then change back to the original theme, and only then can I refresh the page and see that changes I made.
Could it be a server configuration, something to do with caching? Or is it a plugin that might be causing the problem?
P.S I don't even know how to tag this question. Any help will be appreciated. | In the end we disabled all plugins, then turned them on again, and miraculously - the problem disappeared :) | stackexchange-wordpress | {

Check if user is logged in, inside php file in template directory
I have a php file in my template directory which generates some data from a database. I only want this data to be accessable for my wordpress users.
I tried by using this line of code but it gives me an error saying "headers already sent".
What is wrong? Or is there any other way to solve this?
<?php
require_once('../../../wp-blog-header.php');
if (is_user_logged_in())
{
echo "hello world";
}
else
{
echo "You do not have access to this resource!";
}
?> | Since the file is in your theme directory, Wordpress may not want the user to "directly" access it. Why not create a Page in wordpress, assign a Template Name to your PHP page and then assign that to the new page created in wordpress. For example, you would have a new page called "Members Only" and its template is "php-page-located-in-theme". Then, in the code, you don't have to call the blog header, just simply wrap the entire page in your "Is user logged in" if else statement.
Example:
<?php
Template Name: php-page-located-in-theme
get_header();
if ( is_user_logged_in() ) {
echo 'Welcome, registered user!';
/*PHP Generated Content Goes Here*/
} else {
echo 'You cannot access this page.';

Add multiple images to author profile page
I'm developing a directory style theme using multi-site and each new author needs to be able to upload 5-10 photos to be displayed in their profile page.
Is there any way of doing this? I don't mind if it's a plugin as this theme is for a client and not for general release. | You can use this for an author photo: <
And this one might give you multiple images for the author: <

where to split off footer.php
Is there any particular reason why index.php in most templates usually seems to go all the way from just after the start of #main to right before it's closing tag, with that closing tag contained in footer.php. In my theme it would be handy to have #main's closing tag in the index/single/page files not in footer.php ( so the split would be another couple of lines down the code from where i normally see it ).
And if there's no real difference then should i also move the header/index split up a line to get the #main div start tag into the index/single/page etc files ? | It's a personal choice. If the containing markup is consistent across all templates it doesn't matter if they're in the template or header/footer, it's just one less bit of markup that gets repeated in every template. | stackexchange-wordpress | {

WP_query 'orderby=none' Problem
I have another database which stores post's IDs and I want do display them using WP_query to use the WP default pagination. I'm using _orderby => none_ to preserve the original order, but the result reorders them by IDs.

$args = array (
'posts_per_page' => -1,
'post__in' => $ids,
'orderby' => 'none'
);
$query = new WP_Query ( $args );
while ( have_posts() ) : the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;
Could anyone help me?
Thanks, Romulo De Lazzari | You can order them manually after the query is complete:

What makes WP so SEO friendly?
I keep hearing that Wordpress is the best SEO solution, better than most static websites because of multiple reasons. I then go on to hear contradicting information elsewhere. So: Is Wordpress generally more SEO friendly/ready then most static html websites? What makes it more SEO friendly? Can I take any SEO tips from a Wordpress installation to improve a static HTML page SEO? | When you hear about SEO-friendliness of CMS it is essentially same as for static page - how URL looks and what gets into source of page.
Essentially WP is considered SEO-friendly because:
1. It is easy to get pretty permalinks enabled and working
2. There is large choice of themes and plugins, aimed at following recommended SEO guidelines (titles, meta tags, structure of headings, etc).
So this is not about WP being somehow unique. It is about it having tools (both native and extensions) to follow good practices for on-page SEO. | stackexchange-wordpress | {

How to have a custom URL structure for a custom post type?
Even though this question sounds like others here is my problem:
The site I am updating **had** a permalink structure of `/%postname%`, during this time I created a custom post type of "popups" (rewrite slug = 'popups') so the urls were:
/popups/the-post-name
**Now** the site has a blog, and the permalink structure has been changed to `/blog/%postname%`, this changed the custom post type url structure to:
/blog/popups/the-post-name
I want to keep the blog permalink structure as `/blog/%postname%` but I want to have a custom url structure for my custom post type that is not tied to the blog permalink. So instead of the urls for my custom post type of popups showing up as:
/blog/popups/the-post-name
I want it to show up as:
/popups/the-post-name
while retaining the blog permalink of `/blog/%postname%` | When you registered the post type, one of the arguments was rewrite, which took an array. make sure there's a `with_front` argument in the `rewrite` array, and set it to `false`.
<?php
$args = array(
// other stuf...
'rewrite' => array(
'slug' => 'popups',
'with_front' => false
),
// other stuf...
);
register_post_type( 'type', $args );
That should take care of it.
**Important:** Be sure to flush your rewrite rules after changing the code (go to settings > permalinks and hit save). | stackexchange-wordpress | {

Wordpress permalink, stop redirection

WP Cron is "half-failing" to insert posts
I built a plugin for my company, which basically goes to tube sites, scrapes them for content, and posts them automatically in whatever state is defined (publish, draft, future, etc).
Now, everything goes well when I manually add a post through the plugin: it opens a cURL to the sites, grabs the videos and embeds, takes thumbnails, posts titles, flawless. however, when I try to run it from the cron job using
add_action('timelyTube', 'timelyPost');
and on the activation hook:
wp_schedule_event(time(), 'hourly', 'timelyTube');
it works in the sense that it fires the function `timelyPost()`, but when it goes to grab the video, it's not able to do so, it grabs the thumbnails & titles, but not the embeds, meaning that the cURL is working, but something gets messed up in the process.
if anyone has any idea about what to do, I'll be grateful, Thanks, Itai. | Well, I've found my own solution, thanks weston, but I believe mine is a bit easier :)
from the function which calls to insert post, you do the following for simplicity's sake:

I have tried a variety of plugins, but none seem to work out of the box with the featured image. | There's no such thing as a link to a gallery, a post has a gallery by virtue of it having child attachment posts, it's not a separate entity.
You could achieve the modal window by using some sort of lightbox plugin and modifying the gallery shortcode to output the images as just anchor links with the same rel attribute and hide them with css. Obviously that's a bit of custom code, not sure if there's a plugin out there that already does this.
Alternately, you could create separate gallery posts and embed a gallery from another post with the gallery shortcode, then link to those gallery posts. | stackexchange-wordpress | {

Do I Need to Prefix Variables Inside Functions?
Sorry, this is a noob question. But, I want to follow the best practices.

lax_myplugin_myfunction() {
$count = 50;
return $count;

Forcing absolute <img> src links in the RSS feed
We are using relative image URLs in the post's HTML code. Looks like relative src links break on many RSS readers.
By default, Wordpress does not seem to prepare post's HTML for feed too much. Does there exist any solution for post-processing the feed URL and encoring all links and src attributes to be absolute? | Relative URLs are considered bad practice in WP, because of such issues and that they can be much more complex to migrate.
Basic approach to fixing this (not counting changing to absolute URLs everywhere) would be to filter `the_content`, while checking for `is_feed()`, and adjust links on the fly. | stackexchange-wordpress | {

Custom Post Formats
Here's my use case: a client will be making numerous blog posts, some of which are portfolio pieces of his recent work. This sounds like a perfect use case for a Post Format, but no "portfolio" post format exists.
Post Formats are meant to be standardized, common formats, such as gallery, quote, status etc. Unfortunately "portfolio" isn't in that list and doesn't seem to fit with any of the sanctioned post formats.
Creating a custom post type for this seems like bringing a bomb to a bonfire and frankly doesn't sit right with me since the portfolio blog post fits right in with the chronological main blog.
So should I consider extending post-formats (if that's even possible)? Or is that strictly taboo? What's another alternative? | You can't create custom post-formats. What you could either do is have a post category called portfolio and then use the body/post class specific to that to control the display on the front end, as this is what post-formats are designed for, or go for a custom post type. Personally I go by the idea that, if it makes the posting screen less complicated for the client to work with for a specific post type, then a custom post type is the best option.
You can still include custom post types in your standard loop - < so you wouldn't lose that chronological order, it would just make it easier for the client to add portfolio posts, if they are to be so different to normal posts. | stackexchange-wordpress | {

Stop Wordpress from "guessing" redirects for nonexistent URLs
Wordpress sometimes "guesses" a redirection for a nonexistent page slug if the slug is at the beginning of another URL. After some searching, my hypothesis is that this part of the canonical redirection functionality, which can be disabled using this code:
remove_filter('template_redirect', 'redirect_canonical');

function no_redirect_guess_404_permalink( $header ){

return $header;

jQuery('#_your_meta_box_id').hide();

Saving Custom Fields Defined in BuddyPress' register.php
I am writing a custom app for a client that is based on BuddyPress and WordPress. One of the requirements is a custom registration form. To accomplish this, I have managed to hack a custom register.php together inside of a child theme which does the trick. The part where I am stuck, however, is getting BP to save my custom fields without hacking the core. I understand that I might be able to use the "user_register" hook to save the fields but I am not sure if that is the best way and if it is where in the database to store the custom fields. Can anyone point me in the right direction? Thanks!
P.S. I also need a second submit button that redirects to a different page than the normal one for further processing but I may be able to figure this out myself. | Without hacking core files your only option is to use `user_register` hook to save the custom fields and usually custom fields should be stored in the corresponding object meta table, meaning that if its user meta then store it in the `usermeta` table and if its post meta then store it in the `postmeta` table.
As for redirecting after the submit, that really depends on how your form works, if its the regular form then you can simply add an hidden field with the redirect value, something like:
<input type="hidden" name="redirect_to" value="
but if the form is custom and not really using the built in registration form then take a look at **`wp_redirect()`** function. | stackexchange-wordpress | {

Plugin settings page template
When creating plug-ins for WordPress, there are times when you need to make a settings panel. Sometimes, you need more than one page, and they can be quite complicated.
So far, I have been programming/coding them alone. I try to make most of the WordPress original Admin design, but for sophisticated panels, I get a spaghetti of PHP and HTML code. Also, every time, I have to write code that gets the data submitted by the user, analyses and saves it, and return a response.
What solution are you using for your plugins? Are you using a template engine, or just mixing PHP code with HTML? Are there ready framework that offers such a solution?
**Update**
I found the solution to this problem. It's provided by WordPress, and it's very simple and intuitive. This blog post describes how to use the settings API which allows to create a settings/option page with ease. | There are indeed some frameworks

* Rilwis Meta Box Class

Wordpress adds extra width to post images container boxes

Display Registered Taxonomies
Another question. I have a custom post type called "Articles" Within that I have registered some taxonomies using register_taxonomy called "Article Topics" So my client would pop over to Articles, put in a new article, fill out the publisher, and link to where its published, choose the topic its about...all good.
Except: How do i get those "topics" to display in the sidebar. How do i make a sub-nav out of registered taxonomies? Something like this:
<?php wp_list_categories($args); ?>
Is this even a good idea? Or should I just say to hell with it, and go back to categories, and ditch the custom post type?
Thanks.
Nadine | Have a look at the codex page for `wp_list_categories`.

tag.php doesn't work with tags on a custom post type post?
here's another stumper.
I have a tag.php page. It works fine, unless you click a tag that is in a post associated with a custom post type. Then it doesn't work. Its like that tag, doesn't exist. But its just a tag that's used cross site.
I'm not too sure why? And the codex isn't helping much after a lot of searching.
anyone ever run into this issue? I'm stumped.
thanks.
Nadine | If this is related to your other question, what you've got is a custom _taxonomy_ , so you need either a `taxonomy-{taxonomy}.php` template (in your case `taxonomy-article_topics.php`), or just a more general `taxonomy.php` template.
(also, go back and accept answers to your other questions here if they've been solved!)

add this to your `functions.php` template file to show your custom post types on tag pages:
function wpse28145_add_custom_types( $query ) {
if( is_tag() && $query->is_main_query() ) {
// this gets all post types:
$post_types = get_post_types();
// alternately, you can add just specific post types using this line instead of the above:
// $post_types = array( 'post', 'your_custom_type' );

'connected_order' => 'desc',
'connected_from' => get_the_ID()

Redirecting posts in Wordpress to a specific page

<?php wp_list_pages( /* maybe some stuff here */ ); ?>
</ul>

<li<?php if ( is_home() ) echo ' class="current_page_item"'; ?>><a href="<?php bloginfo('url'); ?>">Home</a></li>

WordPress stats: OWA plugin overhead in the future

Does anyone have experience with this plugin? | I hadn't used this specific solution, but any self-hosted analytics in general should be considered potentially huge resource hog:
* every async action in WordPress is effectively another WP core load, so if tracking code makes even one additional async request to back-end it effectively doubles the load;

Using SMTP for outgoing mails (PHPMailer) on AWS instance?

2. Using Custom Contact Forms plugin, specified SMTP the settings so emails are sent using SMTP settings in PHPMailer

Weird google bot crawl problem
I have moved my website to a VPS server. It is a Wordpress + Buddypress installation, latest versions.
I don't understand why I can't see anything when I visit my site with Lynx - a text browser. I can see other sites using wordpress on the same server, but this one doesn't work. Also blogs created on the platform also work fine in Lynx, but the pages of the website don't.
Guess that's why my website also was removed from google search results. | I have found the problem, there was a plugin activated for mobile browsers support - Smooci (WordPress on Mobiles).
The plugin was enabled, and no theme chosen for it. So instead showing the default theme, the plugin, broke out my website - showing nothing/blank page on mobiles.

jQuery in header or footer
From my reading it seems there is a good case for loading scripts like jquery and dependencies into the footer as a preference if possible; however 2 things confuse me which. Firstly the default for wp_enqueue_script() is to put the script in the footer and second (and possibly related) there is a line from the codex
> Note that you have to enqueue your script before wp_head is run, even if it will be placed in the footer.
Is this to say that even if the script is set to load into the footer it still loads early on and so we loose several of the advantages of footer placement?
**Edit** \- Just in case the above incorrect statement confuses anyone in future. I realised since that I'd been reading the codex wrong and that the default for `wp_enqueue_script()` is **NOT** to put the script in the footer | There is a lot of leftovers in script-related articles in Codex that are not entirely correct (putting it mildly).
The enqueue should not be done before `wp_head()`, it should be done on `wp_enqueue_scripts`. Which is technically early inside `wp_head()`.
It doesn't harm performance, because registering/enqueueing script is merely explaining to WordPress how it should be done. Actual script output is done as separate print action.

Star rating for custom post types
I need to add star ratings to one of my custom post types. At first I coded them myself but when the rating challenge came along i thought about using a plugin instead, so I used easy post types.
I've tried a couple star rating plugins and none of them seem to work. For example, with WP-PostRatings, I used the next code in my single-customposttype.php:
<?php if(function_exists('the_ratings')) { the_ratings(); } ?>
The image shows, but clicking does nothing. The same thing happens with other plugins. Star Ratins only says "an error ocurred" but no other debug info is displayed.
So I don't know if you could recommend alternate plugins or any alternate method to add the star rating feature for my custom post type, because can't get it work as it is. | For any rating functionality I always turn to GD Star Rating by Milan Petrovic.
This plugin can do SO many things, including thumb rating, rating of comments, multiple ratings, etc. It can also handle Rich Snippets (for getting your star ratings shown in Google SERPs), caching mechanisms, etc..
In short, it can do a lot, and I generally use it because of its flexibility and capabilities.
You might need to change the code depending on your site, but here is how I have implemented it on one of my sites (in 'single.php' template file):
if (function_exists('wp_gdsr_render_article')) {
wp_gdsr_render_article(10, false,'',16);
}

getting all values of a custom taxonomy if there is no post

attachment.php code or tutorial
I am confused about the exact purpose attachment.php ( and image.php) . I notice many themes dont have them. If single.php displays the image the way I want then is it OK to leave it out. On the other hand could i just make a copy of single.php for attachment.php and leave out the sidebar.
The other thing that confuses me is that when I add a gallery to a post I get the option to open images in an attachment page but when I add a single image to a post it only gives me the option to open the image as an image file (outside of the theme - ie without menus etc). I cant understand the point of this. What is the point in having an attachment.php file for images (or an image.php file) if it isn't going to get invoked when someone clicks on an image.
Ideally what i need is a good tutorial on attachments but I cant find any and i can find very little info in the codex. | This is part of the WordPress template system, it allows you to drill down and further customize output based in the template hierarchy, for instance if you want the attachments to have separate functionality/style then your `single.php`, you simply create `attachment.php` or go even further with `MIME_type.php` (like images).

How to allow YouTube object embed in Wordpress 3+?

Multiple post types in archives (filter?)
I'm trying to get all custom post types to appear in my archive sections on a site, including monthly, tagged, author archives. At the moment, I've thought of something like:
add_filter('pre_get_posts', 'sw_custom_post_type_includes');
function sw_custom_post_type_includes($query) {
$post_type = array('post','custom1','custom2','custom3');
$query->set('post_type',$post_type);
return $query;
}
But I don't want to use pre_get_posts, as this messes with all queries. Is there a filter for, in effect, pre_get_archives? Can't seem to find a solution on Google. | Try this:
function sw_custom_post_type_includes($query) {
$post_types = array('post','custom1','custom2','custom3');
if ( ! is_archive() && ! in_array( get_post_type(), $post_types ) )
return $query;
$query->set( 'post_type', $post_types );
return $query;

Is there a hook that runs after a user logs in?
I am writing a plugin that fetches some extended user info from a remote service and I need it to execute its function each time a user logs in.
Is there a hook that gets fired after login that I can add an action to? | The action hook wp_login runs when the user logs in - it can run a simple function.
function do_anything() {
//do stuff
}
add_action('wp_login', 'do_anything');
documentation : <
The real breadwinner here is `wp_authenticate` which has a bit of documentation. It passes an array with the given username and password, which gives you the opportunity to pass info to the remote service, if necessary. <
and to change the redirect URL after login, there is the filter `login_redirect`: < | stackexchange-wordpress | {

should i be checking for jquery before enqueing it in a plugin
At the start of a typical plugin which uses jquery I have something like the following
wp_deregister_script('jquery');
wp_register_script('jquery', ' false, '1.3.2');
wp_enqueue_script('jquery');
Which as I understand it deregisters and re-enqueues jquery ( from google in this example but that's irrelevant here )
My question is this: is there not some way of checking to see whether the library is already enqueued ( by another plugin or the theme) to save needless deregister/register and enqueue ( or is this not very expensive in reality ) | Enqueues are not piling up if done multiple times (that is kinda the point of having a queue).
As for registration - frankly it shouldn't be done by most (public) plugins. WordPress comes with jQuery to use and when that copy is re-registered to something else - it affects all plugin and theme code that depends on it.
If it's private code - just do registration once somewhere, no need to duplicate it. | stackexchange-wordpress | {

Membership Plugin
I'm looking for a good plugin for premium blog content. My client wants to offer 30 trial that's free as well as a paid monthly/6 months/yearly plan.

It also needs to receive payments through PayPal and automatically turn on the subscription after payment.

Wordpress Hacks/Defacing
Im trying to figure out how Wordpress sites become defaced/hacked. I know development very well. I know how to secure code, etc. But I am finding recently, that tons of Wordpress sites are becoming defaced. Both sites I developed, and others. Is it simply outdated Wordpress installs? Even when Wordpress is running version 3.1, sites are still being defaced.
All user input is validated, both on the front-end and back-end. WP nonces are used wherever possible. Servers are fairly secure (not 777).
????
I'm loosing faith in Wordpress. If it is my fault, I will gladly admit and fix, but the only answer seems to be outdated Wordpress sites, and I find that hard to believe. | > Even when Wordpress is running version 3.1, sites are still being defaced.
_Even_? There had been one major and **five** security releases since that version. If you are implying that 3.1 should be reasonably secure - it is not.
> but the only answer seems to be outdated Wordpress sites
What had you done to exclude themes, plugins and hosting used to jump to conclusion that WP is sole possibility?

Wordpress and Windows Live Writer
I've just been trying windows live writer with my WordPress blog. When I upload my posts from WLW to WordPress and then check them in the WordPress editor, they are a hideous mess of tags etc that describe the formatting (e.g. `<P>` and no line spacing etc), but aren't visible when I create and edit in the WordPress editor.
Is there a way to avoid this as it makes the WordPress editor very hard to use if I need to make edits outside of WLW. Or do people using WLW just give up on using the WordPress editor. I have to say I find the mess very offputting! | In this post, the poster had a problem of HTML tags being stripped of their opening and closing brackets when posting in WP from WLW'.
He explains the source of the problem, and his solution:
> The issue with the partially stripped HTML tags is a bug in libxml2. Specifically using anything less than PHP 5.2.9+ with libxml2 2.7.3+ is susceptible. The fix is to install a plugin into WordPress called LibXML2 Fix which you can get from your plugins menu or look here -> <

Show selected value in a drop down menu
I have a multisite setup and I am adding some additional information fields in the profile edit screen in my theme's dashboard. I am primarily using text fields however I have a drop down selection menu for the author's country
<select name="country" class="mid2" id="country" value="<?php echo $userdata->country ?>" style="width:150px;">
My problem is that if a user selects "Togo" for example it registers the change (I know this because it echoes it in the author's bio page) but the default value in the drop down menu (In this case the United States) always stays the same.
Any ideas on how I can have it display whichever country the author has selected? | Wordpress has a great little function built in for handling selections.
<option <?php selected('value1', 'value2');?> value='foo'>Bar</option>
You can also check out these form handling functions:
* checked() <
* disabled() <
Your HTML syntax is wrong as well. Per W3C, 'value' is not an attribute of the select tag. The value of a select is defined in the options of a select. It should look like this:
<select name="country" class="mid2" id="country" style="width:150px;">
<option value="US" <?php selected('US', $userdata->country);?>>USA</option>
<option value="ES" <?php selected('ES', $userdata->country);?>>Spain</option>

WordPress & W3C CSS Validation
I've played around with WordPress here and there for a few years and am wondering about problems with CSS validation with WordPress themes. This may seems like a stupid question, but:
Is there a reason, relating to WordPress, why it appears no themes I've run across come up error-free in WC3 CSS Validation?
I thought of a number of reason this may be happening:
* Those designing many themes not caring whether or not it pass validation
* I'm getting my themes from not so great sources
* There are quirks with WordPress that force designers to "hack" at their CSS
Just wondering. | There's no reason a WordPress site can't pass validation, it's entirely up to the theme designer. | stackexchange-wordpress | {

Include home page template in specific category template
I have a specific category who's page I'd like to look like the home page of my site, with all the nice sliding featured stories, etc. If I create a file `category-slug.php`, can I do some sort of include of the index template?
If it helps, I'm using wootheme's FlashNews theme. | A somewhat ghetto but fast way to do this is to just use `get_template_part`, for example,
get_template_part('index');
A better use for it is to grab "parts" of your template and not a whole index, but it still works.

Share plugins, themes, and multi post in a multidomain network
I have created a network consisting of 3 sites (site1.com, site2.com, site3.com). Everything works fine, and I can access all three sites fine.
What I need is to be able to share themes, plugins and post to all sites. I have tried multipost-mu, and ThreeWP Broadcast. When I create a post I can now choose the other two sites, but the post doesn't show up there.
The way I set up my network is:
1. My host Setup the dns with a wildcard A record, and setup apache by adding ServerAlias *.|DOMAIN| to my httpd.conf
2. I then added the subdomain
3. I Edit the new subdomain: Changeg the value of Domain, Siteurl, Home, and Fileupload Url to suit to my new domain (
4. I Edit my wp-config.php: define( 'DOMAIN_CURRENT_SITE', 'domain.com' ); changed it to define( 'DOMAIN_CURRENT_SITE', $_SERVER['HTTP_HOST'] );
What am I doing wrong? | Marja,
By default any plugins in the wp-content/plugins directory will be shared across the site. You can **Network Activate** a plugin so it's activated on all sites.
For themes, you will need to **Network Enable** the themes in the network admin panel.
I'm not sure about the posts. That would be a support question for the plugin author that doesn't match the scope of this QA site.

Search Users base on meta_value & meta_key
How can i use multiple meta_key and meta_value to search users?
For example, i want to search & find user name is "David" & location in "London".
I'm using this query, But nothings in result!
$query = "SELECT user_id FROM $wpdb->usermeta WHERE (meta_value LIKE '%%david%%') AND (meta_key = 'first_name') AND (meta_value LIKE '%%london%%') AND (meta_key = 'location')";
$rows = $wpdb->get_results($query);
Thanks | Your query is wrong that's way noting is returned because there is no row in the database that holds more then one meta_key. What you can do instead is create a Sub Query to get all user id's of users who live in London as a Sub Query and the use that to filter users id's of users who are named David, something like this:
$query = "SELECT user_id FROM $wpdb->usermeta
WHERE (meta_value LIKE '%%david%%')
AND (meta_key = 'first_name')
AND user_id IN (SELECT user_id FROM $wpdb->usermeta WHERE (meta_value LIKE '%%london%%') AND (meta_key = 'location'))";

How to query posts by month based on date custom field?
I currently created a custom field for a custom post type that stores a date in the format dd/mm/yyyy is there a way to query the posts by the month?
I "kind of" got the functionality I need using the following query:
`query_posts('post_type=attraction&meta_key=attraction_date&meta_value=10&meta_compare=LIKE');`
The `meta_value` parameter would be the month but since I'm using `LIKE` to compare if I have a date like 10/04/2011 it'd be returned even though it's not from october.
I know there's a `RLIKE` expression in MySQL that lets you use regex for the `LIKE` condition but I'm not sure if wordpress lets you use it in any way.
Thanks in advance! | It is not clear what you're using as a comparison, but `WP Query` supports meta query comparisons and even has a DATE type.
For example:
$query = new WP_Query( array(
'post_type' => 'attraction',
'meta_key' => 'attraction_date',
'meta_value' => '10',
'meta_compare' => 'LIKE',
'type' => 'DATE' ) );
Using `10` is not going to get you very far, you should use a timestamp.
I have not tested the date parameter in WP QUERY, it should be using/converting all dates to a unix timestamp using `strtotime`, if not I would suggest doing so.
