Infinite Scroll on Self-hosted Wordpress
Trying to move a Wordpress website from Wordpress.com to a self-hosted version.
<
The site automatically had infinite scroll on Wordpress.com and I'm trying to implement that on the self-hosted version.
Is that feature part of the JetPack plugin? If not does WordPress offer a way to simulate that functionality on self-hosted? | Jetpack does provide the infinite scroll, but unlike other functionality it may require you to modify your theme to support it.

How to include admin-ajax when loading external javascript
I'm creating a plugin that has some external Javascript and some AJAX calls ... but I don't know the best way to make reference to the `admin-ajax.php` file since the path requires some input from PHP (paths and such).
Should I declare a global javascript variable?
What is the best way to accomplish this? | What you need to do is register and/or enqueue your script and then use `wp_localize_script` to include a Javascript variable on your page. The Codex page has this example:
wp_enqueue_script( 'some_handle' );
$translation_array = array(
'some_string' =>
__( 'Some string to translate' ),
'a_value' => '10'
);
wp_localize_script( 'some_handle', 'object_name', $translation_array );
You can then access the variable with, to quote the same Codex page:
<script>
alert(object_name.some_string); // alerts 'Some string to translate'
</script> | stackexchange-wordpress | {

remove_filter( 'the_content', 'wpautop' ); only for certain post types
I want to try and remove automatic `<p>` tag and `<br>` tag addition for my custom post type.
It looks like
remove_filter( 'the_content', 'wpautop' );
will do this, but how would I make the change only for my chosen post type I've tried writing a function for this, but it doesn't seem to work:
function remove_tags() {
global $post_type;
if ( 'client' == $post_type ) {
remove_filter( 'the_content', 'wpautop' );
}
} | remove_filter('the_content','wpautop');
//decide when you want to apply the auto paragraph
add_filter('the_content','my_custom_formatting');
function my_custom_formatting($content){
if(get_post_type()=='my_custom_post') //if it does not work, you may want to pass the current post object to get_post_type
return $content;//no autop
else
return wpautop($content);
}
found this code on stackoverflow - looks to do the trick. | stackexchange-wordpress | {

how to force caching of wordpress admin
Because of using slow connection these days, I would like to force WordPress's Admin section to be cached in browser (FF,IE) so that it it takes less time to load admin pages (because in fact, most of items never change.). Is there any way to do that? | your problem is not with the admin pages themself, they are simply not big enough to be hugely impacted by slow connection, but with JS and CSS files. You can set an expiry date for them which will signal to the browser it may cache them until that time.
To cache them for a week in your .htaccess file add (idea taken from askapache)
# 1 WEEK
<FilesMatch "\.(jpg|jpeg|png|gif|swf|js|css)$">
Header set Cache-Control "max-age=604800, public"
</FilesMatch>
The max age parameter specifies the time in seconds after which the url have to be fetched again.
If this is not good enough, maybe because your browser cache is full with other files which you access more frequently, then you should install a caching proxy on your PC, configure it to always cache JS and CSS from your site, and configure the browser to use the proxy. | stackexchange-wordpress | {

Running WP Cron on specific local time

// how should change time() to meet my local schedule?
}
add_action('add_daily_task_schedule', 'add_daily_task'); | Not sure what is the question, but the use of `time()` is wrong as it will give you at best the local time of the server and not the local time of the site which takes into consideration the time zone configuration of WordPress.

Disable all scripts and styles from NextGEN Gallery?

<script type='text/javascript' src='
<script type='text/javascript' src='

wp_dequeue_script('shutter');
}
function wpse_82982_removeStyles() {
wp_dequeue_style('NextGEN');
wp_dequeue_style('shutter');
}
But: are you _sure_ you want to do that? Maybe you can be a little selective, and only do that on selected pages / posts / categories.

How can I enqueue protocol relative external (//ajax.googleapis.com/...) scripts?
According to the Codex, wp_enqueue_script supports protocol relative, or protocol agnostic external links: "Remote assets can be specified with a protocol-agnostic URL, i.e. '//otherdomain.com/js/theirscript.js'."
But I'm not seeing it:
wp_enqueue_script('google-maps', '//maps.googleapis.com/maps/api/js?&sensor=false', array(), '3', true);
Output:

Perform action on WPMU blog deletion
Hi guys :) I know there is the `wpmu_new_blog` action hook which enables us to perform an action when a new WPMU blog is created. Is there something similar to this which enables us to perform an action when a WPMU blog is deleted? Something which looks like this:
`add_action('blog_deletion_hook', 'function_to_perform')` | Yes, inside `/wp-admin/includes/ms.php` there is the action hook `delete_blog`.

/**

* @param bool $drop True if blog's table should be dropped. Default is false.

Different logo on homepage

Theme: < | It looks like the theme designer has a means for you to use a different logo on the homepage. Looking at your `header.php` on lines 83-93.
If your theme detects that this is the front page, the title is enclosed with an `<h1>` tag, otherwise it is enclosed in a `<div>`. Both have `id='logo'`.

Target all posts that are NOT aside or link post formats
I want to add a post title to all of my posts apart from those that are marked as "aside" or "link" post formats.
I'm currently using this code to hide the post title for aside posts;
<?php if (! has_post_format('aside')) { ?>
<?php the_title();?>
<?php } ?>
How can I target the "link" post format aswell using this method? | **Edited:**
Now that I understand your question, try this...
Place this above your title to enable the post_class function.
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
Then add `</div>` below your title (or excerpt, or wherever you want this special styling to end).
Now, a special class will be added in which you can use the classes for post formats. for example, you may now use `.format-aside` in your CSS to style the aside. | stackexchange-wordpress | {

prepare() not working
When I do this:
$transients = $wpdb->get_col(
"
SELECT option_name
FROM $wpdb->options
WHERE option_name
LIKE '_transient_wb_tt_%'
"
);
It works fine, but when I use prepare like so:
$transients = $wpdb->get_col( $wpdb->prepare(
"
SELECT option_name
FROM %s
WHERE option_name
LIKE '_transient_wb_tt_%'
",
$wpdb->options
) );
It doesn't work, what am I doing wrong here? | I agree with @bainternet. You don't need `$wpdb->prepare`. There isn't any user supplied content.
The answer to the question is that to get a wildcard `%` to pass through `prepare` you need to double it in your code.
LIKE '_transient_wb_tt_%%'
Try that or this if you want a good look at the generated query:
var_dump($wpdb->prepare("
SELECT option_name
FROM %s
WHERE option_name
LIKE '_transient_wb_tt_%%'
",
'abc'));
die;
Other than being unnecessary, using `$wpdb->prepare` like this won't work. The attempt to use `prepare` to swap in the tablename will result in a tablename with quotes around it. That is invalid SQL. The query should be simple:
SELECT option_name
FROM {$wpdb->options}
WHERE option_name
LIKE '_transient_wb_tt_%%' | stackexchange-wordpress | {

Taxonomy Tag Conditionals

}else{
jigoshop_get_template( 'product_taxonomy-no.php' );

thanks | If you want to use an entirely different template, you could filter `404_template` and check query vars for a specific taxonomy:
function wpa83050_404_template( $template = '' ){
global $wp_query;
if( isset( $wp_query->query_vars['product_cat'] ) )
$template = locate_template( array( "product_taxonomy-no.php", $template ), false );
return $template;
}
add_filter( '404_template', 'wpa83050_404_template' );
You could also just put logic similar to the above in your 404 template and use that single template for all 404s, check `$wp_query` for what query vars are set and print some text accordingly. add `var_dump( $wp_query );` to your template to see what query vars get set under different conditions. | stackexchange-wordpress | {

Trigger a cron every 24h GMT -8
I' like to run a cron every 24 hours at midnight PST ( = GMT -8 )
This is what I have
if ( !wp_next_scheduled( 'cron_hook' ) ) {
//reset on 00:00 PST ( GMT -8 ) == GMT +16
$timeoffset = strtotime('midnight')+((24-8)*HOUR_IN_SECONDS);
if($timeoffset < time()) $timeoffset+(24*HOUR_IN_SECONDS);
wp_schedule_event($timeoffset, 'daily', 'cron_hook');
}
This sets a daily cron on midnight GMT -8 (24-8) and postpone it 24 hours if it's already in the past so the cron doesn't get triggered at the time of creating.
Am I correct with this approach or do I miss something?
I've already tested it but since my server is running with GMT + 0 I cant verify that for other timezone | Almost,
WP Cron jobs do not run at specific times, they are approximate, and all timestamps should be UTC, as WordPress **_always_** deals in UTC timestamps. If you want midnight PST, you'll want to specify 8PM UTC.
Also for example, your above code suggests midnight PST, but it may not run at midnight PST. If nobody visits the site at the specified time, and there's 4 hours before someone arrives, then the cron job will occur at 4am.
If you're wanting accurate cron jobs that are not approximate, you will need to setup a server cron job to call the wp cron URL at fixed intervals.
I would also choose a more specific name than 'cron_hook' to prevent clashes and issues in the future
You can test this easily by just figuring out what time midnight PST is in UTC, aka 8AM, does your cornjob fire at 8AM UTC? | stackexchange-wordpress | {

Displaying child page content of a certain parent
What I would like to do is to create a WP loop that will display info from a child page of an adult page ID, so the Page ID is 2. I would like to pick a page ID to display what page.
So that way I could display information from another child page on an alternative page.
Owen | This is a near duplicate of a number of questions here, but the "single random result" might make it somewhat distinct.
$args = array(
'post_type' => 'page',
'post_parent' => $post->ID,
'orderby' => 'rand',
'posts_per_page' => 1,
'no_found_rows' => true
);
$child = new WP_Query($args);
var_dump($child->posts);
You are telling `WP_Query` to pick 1) pages, 2) with the parent of the current page, 3) ordered randomly, 4) one result, and 5) don't bother tracking found rows since we already know it should be 0 or 1.
There are numerous examples of creating multiple loops here and in the Codex. You should be able to find plenty of information to flesh this out. In short you want:
while ($child->have_posts()) {
$child->the_post();
var_dump($post); // raw dump of your child post

How can i listing current category and Featured Category post list?

<li><a href="<?php the_permalink(); ?>">
<?php the_title(); ?>
</a> </li>
<?php endwhile; else: ?>
<?php endif; ?> | I think you're asking about your custom secondary loop affecting your main loop, correct?
`query_posts()` alters the main loop. A quick fix would be to call `wp_reset_query()` after your custom loop to reset the query data:
<?php wp_reset_query(); ?>
However, it's more efficient and friendlier to use `WP_Query()` instead of `query_posts()` (especially if you're making a secondary loop). This should be the equivalent of your provided code using `WP_Query()`:

if ( is_category() ) {
$current_cat = get_query_var('cat');
}
$args = array(
'category__and' => array( 55, $current_cat )
);
$my_query = new WP_Query( $args );
?>

Deleting a custom field field
Is there a way to delete a custom field (in the sense of complete removal from WP database) without using a plugin? | If you have access to phpMyAdmin, these steps should do the trick:
> Step 1: Login to your hosting account and launch myPHPadmin from the cPanel, or equivalent, to access the WordPress database engine.

> Step 2: Enter a select SQL command to list all the meta keys you want to remove. In this example, I want to find and eventually remove the meta key dcssb_short_url.

>
> SELECT * FROM 'wp_postmeta' where 'meta_key' = 'dcssb_short_url'
>
>
> Step 3: Once you are satisfied you’ve narrowed down the selection, issue a delete SQL command to remove the rogue data
>
>
> DELETE * FROM 'wp-postmeta' WHERE 'meta_key' = 'dcssb_short_url'
>
>
> Step 4: Issue the same select SQL command again, to verify all the offending records have been deleted.
>
>
> SELECT * FROM 'wp_postmeta' where 'meta_key' = 'dcssb_short_url'

Avoiding using a loop to access a single post
Sometimes I want to access one particular CPT to extract something from it, for example a custom field value:
$group = new WP_Query( array(
'post_type' => 'group',
'p' => $group_id
) );
while ( $group->have_posts() ) : $group->the_post();
$group_type = get_post_meta($post->ID, "group_type", $single = true);
endwhile;
However the purpose of a loop is to access more than one element so I dislike using a loop for a single post. Is there a way to do exactly the same thing (accessing this custom field value) without using a loop? | how about get_post?
$post = get_post( $p );

Buddypress Language Files Question
I have one question. I use latest Wordpress and Budypress. I have language files for buddypress - .po and .mo. My question is where I need to put the files, how I need to rename them and is there any function that I need to add somewhere (for example functions.php) to load them. I checked this page and try to follow the instructions, but my site is still in english.
Thank you in advance :) | The naming convention for plugins translation files (`.mo` and `.po` files) is `pluginname-language_COUNTRY.mo`. So, for example, a French translation files of Buddypress will be: `buddypress-fr_FR.mo` and `buddypress-fr_FR.po`. After renaming these files, put them in `wp-content/languages` directory and your translation should work. Note that `WP_LANG` must be defined with the same language (`fr_FR` for example) for the translation files to load. | stackexchange-wordpress | {

Updating client websites on a regular basis
I hope the following question is acceptable here, as it's half WordPress-related and half-business related.
Updating WP regularly is important for security purposes, but it can be time consuming if there are many websites to update and even more if some updates require plugin updates (and in some cases, a plugin ceases to work after WP update which potentially requires a time-consuming solution).
What is the best solution to address this ongoing problem? Should WP regular updates be charged for example? Should it be mentioned in the initial contract? | I don't think there's a best solution, but whatever you decide to do, speak to the client about the issues, reach an agreement and put it in writing. I think it's important to discuss why we are using WordPress/theme frameworks/3rd party plugins, and what that means. The advantages: vastly reduced development time, a great community, etc., and the potential disadvantages (plugins that break). One option is to offer six months of free support, then charge by the hour after that. As long as the client is comfortable backing up their WP installation, then I see no reason why they can't update the site themselves. If something goes wrong, they at least have a backup. | stackexchange-wordpress | {

WooCommerce: How to edit the get_price_html
I am trying to edit the price value for a single product.
In `single-product/price.php` there is a template call to `$product->get_price_html`. How can I edit that function/method to change the way the HTML is presented?
At the moment even if I delete all the contents of the function located in `class-wc-product` it still miraculously displays? Anyone know why? | Core and plugin files should never be edited directly, as any updates could overwrite your changes. If you look in WooCommerce source at the `get_price_html` method, there are a number of filters available to modify the output of the function.
See `add_filter` in Codex for more info on adding filters to `apply_filters` calls.
From `get_price_html` in `class-wc-product`:
return apply_filters('woocommerce_get_price_html', $price, $this);
So to add your own filter:
add_filter( 'woocommerce_get_price_html', 'wpa83367_price_html', 100, 2 );
function wpa83367_price_html( $price, $product ){

Hide meta box based on post format

Using wp_get_image_editor in a standalone script
With WP 3.5, they updated the image resizing scripts with `wp_get_image_editor`.
Currently, in this standalone script that is accessed with Ajax, I have included `wp-load.php` so I can access all of the WP functions. Particularly, `$wpdb;`. In order to use the `$wpdb` functions, I had to declare `global $wpdb;` first.

When using:
$image = wp_get_image_editor($current);
//if (!is_wp_error($image)) {
$image->resize(100, 100, false); }
nothing happens, and if I remove the `if` statement, I get the error
> PHP Fatal error: Call to undefined method WP_Error::resize()
Does anyone know how I can do this? Would it be smarter to install my own image-resizing scripts? | Turns out I'm just silly.
WP_Error was the undefined method, not resize. I was sending a bad image location through the resize function. How silly of me! It was working all along.

require_once( $parse_uri[0] . 'wp-load.php' );

Pls share if there is a way to do this, or what it would take.
TY | It sounds like "Featured" or "Thumbnail" images would work. These are enabled by default for 'posts'. For 'pages' they need to be enabled, but that is as simple as adding `add_post_type_support( 'page', 'thumbnail' );` to your theme's `functions.php` hooked on `init`, and, of course, modifying the theme template files to display the featured image.
function add_featured_to_post_wpse_83508() {
add_post_type_support( 'page', 'thumbnail' );
}
add_action('init','add_featured_to_post_wpse_83508');
The theme itself has to register its support with `add_theme_support( 'post-thumbnails' );`

However, both GIDZipTest and Google Page Speed Insights Chrome extension say that compression is not enabled.
I added the following to my .htaccess file, and they still say compression is not enabled:

AddOutputFilterByType DEFLATE text/html

AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
**UPDATE** : I have since disabled WP Super Cache, and I'm testing W3 Total Cache. | W3 Total Cache is working; compression is being performed correctly. | stackexchange-wordpress | {

Weird lightbox phenomenon
I have one weird thing happening with lightbox on my website. If I add a lightbox image or gallery and then click on the image, the first time it will navigate directly to the image file. If you then click the back button and click the image again, lightbox loads up normally.
Any thoughts on why reloading the page after the first click makes lightbox work properly?

Why Does get_posts() Return an Empty Set?
I'm writing a custom plugin that is initialized at `init`. This plugin is trying to query for some custom post types already stored in the DB.
Here's my code:
$args = array()
$myposts = get_posts( $args );
print_r($myposts);
No matter what arguments I pass into the $args array I don't get anything. For example:
$args = array( 'post_type' => 'page' );
Now, to my confusion if I use the exact same arguments with `get_pages()` I get a result.
Maybe this has something to do with when WP Query is initialized? | It seems that is was a simple problem. get_posts() has various default settings, one of which is that the `post_status` is set to `public` and my custom post type which doesn't use `post_status` used the default value, `draft`.
To fix this you can either query by post status (see the code below) or change the data in the DB.
$args = array(
'post_status' => 'draft',
'post_type' => 'your_custom_post_type'

How to gain access to each menu item in wordpress?

javascript is not working on Event Submission?

How to copy an existing (custom themed) site to a new domain
I'm trying to find a way of duplicating an existing Wordpress site that uses a custom theme to a new domain. Once it's there I'll do a redesign of the site and redirect the old url to the new one.
Just briefly... I tried following the instructions @ < but when it told me to "3.Go back to your OLD blog and go to options and change the url (both of them) to that of your new site." It logged me out and caused about 3 hours of trying to get it fixed again !!

Optimizing site speed by localizing paths
I read an article (which I didn't save) that argued you can improve the performance of your site by changing all file paths to full paths, so for instance, instead of `<img src="<?php bloginfo('template_directory'); ?>/images/headers/image.jpg" />` we go with `<img src=" />`.
My platform has its own theme, meaning that it will only be updated if we update it. So changing paths should not be an issue. Also, the article suggested that you do the same type of changes everywhere, e.g. script files, `functions.php`, plugins (if you can be bothered to redo it every time they update...).
So the question is, how much performance will this improve? Surely sending less requests on a page load should make some very minor, but noticeable, improvement? | This is nonsense. Almost all URL getters are a result of `get_option()`, eg. `get_option('stylesheet_root')`, `get_option('template')` and so on.
These options are loaded very early during the request, they are cached and not fetched again.
Since the options are fetched anyway, all you can improve is processing time. Nanoseconds. This isn’t worth the trouble. Just compare to the time you need when you have t change something in all those files (switching to HTTPS, to a sub-domain, changing permalinks).
Install a good caching plugin. That will improve load time much, much more. | stackexchange-wordpress | {

Adding admin-ajax.php to the frontend. Good or bad idea?
I love admin-ajax.php. But I hate having to localize in order to point frontend scripts to it, and I wish there was an equivalent, easy-to-find file for themes. (It also just bothers me to see frontend requests go through "/wp-admin/". No practical reason, just looks ugly IMO.)
So I've simply copied admin-ajax.php to the root dir at "/ajax.php", adjusted the include paths and removed the WP_ADMIN constant definition. Seems to work like gangbusters (I can now just direct all my frontend AJAX requests to /ajax.php! And I can still use the normal wp_ajax hooks in my plugins!).
But is this safe? What might go wrong? Since this isn't built into core, I assume there's a good reason as to why not. But looking through the code, I can't see any immediate problems.
You're smart--tell me if this approach is crazy. Or if there's a simpler method that I'm overlooking. | You could just use a RewriteRule to your .htaccess above the regular permalink rewrite rules:

How to Add a Custom Size for Thumbnails for WP - Gallery
I am using "Lightbox Plus" plugin to create lightbox image overlay on the top of thumbnail galley.

I mean when I try to set a scale for Thumbnails through wp-Gallery edit option it apply the size even to the overlays (I would like to keep the overlay size as big as possible but this function makes them small like Thumbnails size) I also see this line of code in codex:
`get_the_post_thumbnail($id, array(100,100) ); // Other resolutions`

Re this comment:
> Thanks for comment but honestly I got more confused!can you please let me know what is the 'custom-name'? How I can associate this name with Gallery thumbnails?
The `custom-name` is arbitrary. It's whatever you want it to be. You could call it `gallery-thumb`, if you want to:
add_image_size( 'gallery-thumb', 123, 456, true );
Then, you would output that image size by passing `gallery-thumb` to `the_post_thumbnail()`:
the_post_thumbnail( 'gallery-thumb' );
In your case, I assume you're using the [core WordPress `[gallery]` shortcode]( If so, you can pass the `size` attribute:

How to load javascript on custom page template?
I have a custom page template where I would like to load some javascript. I suppose I could always include the javascript in the actual file, but that seems ugly. Is there any way to identify if WordPress is loading my custom-page.php file so I can enqueue the script only on that page?
It should work dynamically, so checking page id is not an option. | You can use **`is_page_template`** to check if you template is being used and load your scripts based on that ex:
Add this code to your functions.php:

function Load_Template_Scripts_wpa83855(){
if ( is_page_template('custom-page.php') ) {
wp_enqueue_script('my-script', 'path/to/script.js');

Can I hook into user registration *before* a user is created?
I want to limit registration based on the domain associated with their email address. I was looking at the `user_register` action hook, but it fires _after_ the user is already inserted, which, although it could be hacked into working, is less than ideal. I want to preempt rather than retroactively remove invalid users.
I've looked through the source in `wp-includes/user.php`, but nothing in there looks to be helpful. I did notice the `pre_user_email` filter, but that doesn't seem to offer any options for doing anything useful since I can't see a way to do anything with that. | You're looking in the wrong place.
When a user first attempts to register, their username and email is processed and sanitized inside the `register_new_user()` function in `wp-login.php`. This is where you want to do your filtering.
Before the user is created, WordPress will pass the sanitized user login, email address, and an array or errors through the 'register_post' action. If there are any errors after that, then the user is not added and they will see the errors in the UI.
So the following _untested_ function might help:
function prevent_email_domain( $user_login, $user_email, $errors ) {
if ( strpos( $user_email, '@baddomain.com' ) != -1 ) {
$errors->add( 'bad_email_domain', '<strong>ERROR</strong>: This email domain is not allowed.' );
}

How to remove a settings section from the Theme Customization API preview pane?

Deep customization of the comment form?
I've been handed over a design to translate into WordPress plugin & theme. My question is regarding building a custom comment form.
The design used some custom scripts on the comment submit button. It handles 'submitting...' button state, animations, and checks. And it uses an anchor tag `<a>` with jQuery's `.bind` to submit the form.
I noticed that the `comment_form` function of WordPress did not offer a solution to change the submit button. I only needed to remove it as I'm handling it myself.
What made it worse is that WordPress has hard coded `<input name="submit">` into the button, which made it impossible for jQuery to call `.submit` (more details on this issue here: < So just hiding this button with CSS won't work.
If I prefer not to use the `<input type="submit">` button of WordPress comment form, do I have any options to build my own button?
Thanks. | This is hard. Output buffering could solve that:
add_action( 'comment_form_field_comment', 'ob_start' );

Generate aggregated feed from member blogs
I currently manage a multisite installation with 7 member blogs. We need to produce a combined RSS feed of news from all 7. Currently we use Feedwordpress to syndicate 6 blogs into blog number 7. This isn't working out because we're duplicating content in the db.
Ideally I need a cached feed to reduce server load (the feed is subscribed to via high-traffic portals).
What's the best way of doing this? I've considered Yahoo Pipes, but how about using Wordpress transients to cache a query across all member blogs, and somehow publishing this as RSS?

Better in the long run to use post date or custom taxonomy to sort/separate posts by year?
I have custom type posts that I need to separate by year as the posts are entries in an annual contest. Would it be better in the long run for efficiency of queries, speed, etc to simply use the built in post date or set up a custom taxonomy to group these posts into years?
I notice that post_date is stored in the wp_posts table, so it seems to me that this would make for speedier queries than having to reference the separate taxonomy table.
Thank you! | I can't see any practical reason to use a custom taxonomy here. You can already query posts by year using OOB query and archive stuff (see this Codex article about the "year" WP_Query parameter, and this one about the "yearly" mode for wp_get_archives()).
If you're asking purely about performance, I'd consider this kind of thing (a single table query vs. a simple join) a "micro-optimization". For 95% of WordPress sites, it won't make any visible difference. And if your site is at the point where you need serious tuning, there are probably better places to focus energy (like identifying _really_ slow queries, and having a good caching strategy).

Accessing + retrieving custom database in WordPress
I am looking for something really simple(?). I am using WordPress as a CMS. I created a new page in which I added a form (questionnaire). Inside WordPress' database (the same database in which all WordPress data are), I created a new table called "ExampleTable".
Now I have 2 questions:
1) How can I insert data from the form into that custom table? 2) Is is "okay" to add a custom table (which has nothing to do with WP inside WordPress' database, or should I create a new database?)
Thanks :) | It is OK. And you can access this table with standard way, throught wpdb

global $wpdb;
$wpdb->insert(
'exampleTable',
array(
'column1' => 'value1',
'column2' => 123
),
array(
'%s',
'%d'
)
);
To breafly explain what this code mean. WordPress sanitizes values before inserting them into database (to prevent database being compromited by SQL injection.). First line defines table to inser value. Secon array contains col names and value being inserted. The third array contains type of value to insers. %s stands for string, %d stands for int (digit).

Auto log in hook is requiring a page refresh

How to show animal lineage/pedigree in WordPress?

create functions based on array values
I am working on a function set that will add a piece to each custom post type on a site. Since I won't know what CPTs are registered, I wrote a function to get them all (simple). However, I now need to create a function for each value in an array (a small settings page) to properly finish this off.

You could use __call in your class and call your function for grabbing the page types and check them against the $name (first) argument and running custom code against it.

$types = array ('type_a', 'type_b', 'type_c');
if (in_array($name, $types) {
// custom code
}

Minimum Template Files for Theme Development
WordPress has minimum theme template files as
* style.css
* index.php
and also some other files as listed here.
If the theme developer wants to build theme with less bells and whistles, what are some of the template files which should be included at minimum? There isn't any guidelines in the WordPress codex. Only thing that you can find is what files and when to include them. For making use of most of the WordPress functions without any conflict, there doesn't seem to be specific number mentioned for number of template files.
So how many files should be there when you build a theme from say raw html template? | To have the theme listed:
* `style.css`
With at minimum this:
/*
Theme Name: Minimum Theme
Description: Test
Author: Test
Version: 1.0
*/
For the theme to be functional:
* `index.php`
`index.php` must have a post loop, so this would be the bare minimum functional `index.php`
<html>
<head><?php wp_head(); ?></head>
<body>
<?php
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
the_title( '<h3>', '</h3>' );
the_content();
}
}
wp_footer();
?>
</body>
</html>
index.php is the defacto fallback for all template files WordPress might look for. All the rest are entirely optional, though I advise that you use them.
