Is it possible to get all term items from a custom taxonomy regardless of post attachment status?
Essentially, I build web sites with galleries, for photographers. Up until now, gallery images have all been attached to posts and I've just pulled from the category taxonomy. This is messy if it's also to be used as a regular blog.
So I've been poking around and I discovered things like if an attachment item isn't assigned to a post, it has a `parent_post ID` of **0**.
If I could, how would I go about simply getting all items with a term in my custom taxonomy, ignoring their `parent_post IDs`?
I'm getting the feeling Wordpress just isn't quite there yet, for what I would like to do... | If I understand right, you need all attachments (attached or not) with specified term?
$args = array(
'post_type' => 'attachment',
'my_taxonomy' => 'my_taxonomy_term'
);
$my_query = new WP_Query( $args );
if( $my_query->have_posts() ):
while ($my_query->have_posts()) : $my_query->the_post();
// your stuff here
endwhile;
}
// Don't forget to reset
wp_reset_postdata();

new WP_Query all post in a category inside the loop
Im trying to get a list of post in a category with this:
$category = get_the_category();
$args = array(
'post_type' => array('post', 'entrevista'),
'cat' => $category[0]->term_id,
'post__not_in' => array(get_the_ID()),
'ignore_sticky_posts' => 1,
'posts_per_page' => -1
);
$queryScience = new WP_Query( $args );
unset($args);
?>

<?php endwhile; endif; wp_reset_query(); wp_reset_postdata(); ?>
I think it goes infinity loop because shows more than 40.000 results. What am I doing wrong? | You have to call `the_post()` within your loop, otherwise you'll output the first post in an infinite loop, as `have_posts()` will always be true.
$queryScience->the_post();
Also, you don't need `wp_reset_query()` with `WP_Query`, `wp_reset_postdata()` is enough. | stackexchange-wordpress | {

Is it possible to animate the Twenty Eleven menu?
I have a menu in my Twenty Eleven child theme that has some hierarchical items. Twenty Eleven handles it just fine, of course, but my client likes the fancy-looking menu animation that you can see on this site. I don't need the horizontal style that shows up under the "Resources by Topic" item, just the on-hover expansion like the "Who We Are" heading. I have used jQuery quite a bit before in other (non-WordPress) websites, but don't know where to begin in this case. Is this animation possible with Twenty Eleven? | The answer is yes. It is possible with some jquery. I think your question is still too broad. Also, asking for plugin recommendation is on the don't ask list. Id start doing some Google searches for implementing jquery in a wordpress menu, attempt and maybe ask for help with your code if it is not working. Otherwise a quick search for wordpress menu plugins will give you lots of addon choices. | stackexchange-wordpress | {

How to insert link to the default post archive into a menu
I can add categories, I can even add a custom post type archive, but I can't add the original posts archive.
It's not among the page list.
I worked around this by creating a page, creating a page-pagename.php file, displaying the posts there and linking to that page, but when that page is shown, the menu item doesn't have the 'current-menu-item' class. | Instead of finding out how to put a custom archive link in the menu (which would still be nice to know), I found the problem with my custom page template solution.
To display the posts in the News page template I obviously had to alter the original query, which carried the News page record. Since the footer, which was outputting the menu, only came after the loop, it couldn't find out which page it was on - hence it couldn't correctly assign the current-menu-item class.
All it took was a `wp_reset_query();` command after the custom loop and we're good. | stackexchange-wordpress | {

Is it possible to change the log file location for WP_DEBUG_LOG?
I use WP_DEBUG_LOG in my development environment and have no issues with debug.log being in the wp-content directory.
Sometimes I turn on WP_DEBUG in production when I need to debug something, and I still want to use the log but would like to redirect it to something outside my web root. Is this possible using WP_DEBUG_LOG? | It turns out that all WP_DEBUG_LOG does is:
ini_set( 'log_errors', 1 );
ini_set( 'error_log', WP_CONTENT_DIR . '/debug.log' );
So, if you want to change the log location for WP_DEBUG_LOG in a plugin or theme, webaware's answer is best. If you just want to have it changed within `wp-config.php` you can replace `define( 'WP_DEBUG_LOG', true );` with the above 2 lines and change the log file to wherever you want. | stackexchange-wordpress | {

How to disable commenting from Twenty Ten theme?
This is a terrible user experience when I'm trying to do the most simple thing and it never works. There are many pages with "instructions" how to do this and none of the "instructions" work.
Now we hate Wordpress for making the most simple thing just not possible.
## Solution ##
This only worked when doing it via the quick-edit which is disastrous since there no instruction that says so. We should get our money back for this crap. | WordPress admin screen -> Settings -> Discussion -> "Allow people to post comments on new articles". Uncheck it.
For existing posts, go to Posts -> All Posts. You can click "Quick Edit" on any post to find the "Allow Comments" checkbox and turn them off for that post.
To bulk-edit existing posts, you can select all the posts you want to edit at once using the checkboxes, then use the "Bulk" feature at the top of the page. Select "Edit" from the dropdown, click Apply. Then in the bulk editor, change the Comments dropdown to "Do not allow" to change that setting on all the selected posts.

How to get twenty ten content side by side (images and/or text)?
I try to align content side by side. I tried this solution from the Wordpress forum but it is not working for me: < | I had to guide a user through this recently, some tricks that I found:
1) Make sure the HTML is clean, that fidding in the visual editor has not added in extra paragraphs or alignments or whatever. In fact, take out all the alignleft etc. you can, get it back to a virgin state.
2) In the visual editor, select the image so it turns blue.
3) Make sure the little mountain icon is displayed on it; if not it means you've got the container selected or something like that, not the image itself
4) Click the align left icon to move the image to the left.
5) If that still doesn't work right, experiment with which image goes first in the HTML; when floating images like this it matters what the sequence is and what is inside what.
At the moment in your HTML it looks like both images are aligned left, resulting in them not being side by side. | stackexchange-wordpress | {

Can't get custom user meta to show in header

what is the difference between timthumb and post thumbnail?
I get the image through wordpress built in post_thumbnail, but i see a lot of developers use timthumb for that and i don't know why! is it more flexible or something? | There are two reasons:
1. post_thumbnail was introduced with WordPress 2.9, and many themes which used TimThumb because post_thumbnail wasn't yet available to them.
2. TimThumb is more flexible than post_thumbnail — it gives you more options for how images are cropped, and allows for simple filters to be applied to the images.
However, TimThumb has also caused security issues, especially with sites which didn't keep their themes (and because of this their timthumb versions) up to date. Because of this, it often makes more sense to use post-thumbnail, especially if you don't need much beyond WordPress' built-in cropping for thumbnails. | stackexchange-wordpress | {

query posts and custom post type with meta key
I'm trying to query all-in-one-event-calendar's custom post type ai1ec_event and normal wordpress posts in a slider on my home page. That works pretty well.
Now I want to query only the posts with the custom field value "teaser", but that returns just normal posts, not the events.

query_posts( array(
'post_type'=>array('post','ai1ec_event'),
'posts_per_page' => 50,
'meta_query' => array(
array(
'key' => 'teaser',
'value' => 'on'
)
)
);

Even if I leave out the post type query:
<?php
query_posts( array(
'meta_query' => array(
array(
'key' => 'teaser',
'value' => 'on'
)
)
);
?>
it only returns posts, no events. | I'm afraid WP_Query is not able to fetch (Posts with custom field) or (ailec_even). You'll have to query the firs one, than the second one and merge those arrays. Use WP_Query instead of query_posts.
I've just tried it on my local installation and this code called from index.php of twentytwelve works (brings post with title "Hello post" and ai1ec_event with title "Event" - both with custom field "teaser" with value "on"
$events_query = new WP_Query( array('post_type' => array('ai1ec_event', 'post'), 'meta_query' => array( array( 'key' => 'teaser', 'value' => 'on' ) )) );
while ( $events_query->have_posts() ) :
$events_query->the_post();
echo get_the_title() . '<br/>';

Upload a custom csv file, read contents and delete that file
Can someone please direct me to a resource or give me some pointers on:
* How to upload a csv file to wordpress (media uploader or alternate methods, ajax powered preferred)
* Access that file so I can read the contents
I am not looking for a plugin as this is a custom file that I need to read and process inside a plugin.

Bold steps interest me the most. | 1. Enable upload of CSV files, which are not in the default allowed files (see here)
2. Hook into add_attachment action hook to detect when the desired file is uploaded
3. Do whatever you need to do using that hook, then trigger wp_delete_attachment once the file has been processed.
Depending on what you want to do, it may be beneficial to craft your own upload setup outside the default Media Manager where it would be easier to detect when a file uploaded should be processed by your plugin. | stackexchange-wordpress | {

WordPress Translation to french, at -> à not working
I have a german / french blog. I installed the german WordPress version, so I already had de_DE.mo and de_DE.po in wp-content/languages. After I realized that the content of a comment's `<time>`-element wasn't translated, I googled and downloaded fr_FR.mo and fr_FR.po and put them in wp-content/languages. Now everything I tested works, except that 'at' doesn't get translated to 'à' ( I get: 3. février 2013 at 17:00).
So I opened fr_FR.po to see whether there is a translation available. I found this:
#. translators: 1: date, 2: time
#: wp-includes/comment-template.php:1367
msgid "%1$s at %2$s"
msgstr "%1$s à %2$s"
Which seems alright to me. So to make sure, I replaced the existing mo file with this. Still it does not work.
How do I make it translate 'at' to 'à'?
I'm using WPML. | No matter what languages your site are in, when using WPML you should **never** install a localised WordPress version, instead you should just install the default one (i.e. US English).
Also make sure that you didn't change the LANG definition in your `wp-config.php` file, so that should read: `define ('WPLANG', '');`
Then you need to make sure that all the strings are in English (go to WPML->String Translation, scroll down to the bottom where you can set the language of the strings). After that rescan your theme for strings and you will be able to add translations for "at" in both German and French. | stackexchange-wordpress | {

Get URL Parameters from referer
Not 100% sure if this one classes as a php question or is specifically Wordpress...
I'm implementing the Wordpress Settings API with a tabbed settings page. I've added a 'reset tab' button, but since the validation is done on a separate page (options.php) I can't seem to figure out which tab I'm on - without adding the tab as a hidden field, which I want to avoid.
I've found the `wp_get_referer()` function, but that gives me the full URL - I'm not sure how to pull the `tab=tab1` out as a variable.
**Update - Answer:**
$url = parse_url(wp_get_referer());
parse_str($url['query'], $path);
$tab = $path['tab'];
As said in the answers, some validation is then required. | If `tab=tab` is in the URL then:
global $_GET;
var_dump($_GET); // debugging only; You should be able to see what you need.
That is pure PHP. If your really need to process that string (I don't know why your would) use `parse_url` then use `parse_str` on the `query` part of it.
$path = parse_url($url);
$path = parse_str($path, $output);
var_dump($output); // again, just debugging
For completeness, please don't use any of those values without validating them.

Use an archive as the parent of a page?
how can I solve the following problem?
I have the category "Events" with the permalink `www.myblog.com/events/` and of course single events like `www.myblog.com/events/lets-party/`. Now I want to add a custom page "Event Contacts" which should be located below "Events" like `www.myblog.com/events/contact`. But I can't choose category archives as a parent page in the backend.
Any advice? | Once wordpress reads the "Events" part of the URL it knows that what follows are posts or subcategories of the events category, and a page is neither, and that is the reason you don't even have an option of doing what you want.
Do it as a post instead of a page. Then edit you single.php to have special treatment for your contact post id if you need it. If you are lucky it might be enough to change the css for the specific post.
Alternatively you can try to use the fact that if all other URL parsing options fail, WordPress tries to parse the URL as page, and add a page with the slug "Events" and contact as its sub page. If you go that way you need to always remember not to create sub categories or posts with the slug contact. | stackexchange-wordpress | {

How to back-up a database on IIS

Arrange custom fields with drag and drop?
I am making theme for hotel and i made custom metabox with list of various custom fields that i would need in posts.
What i did is i made a list of fields like
* booking
* wifienabled
* coffe
* pool
* spa
and so on...
Problem is that currently i can show those custom fields in website frontend only by order how i added them in array, if i change places in my list custom fields will change places in website frontend.

PHP unit testing WordPress?
Given how WordPress is written and how it interacts with a database and given how its not very much OOP oriented, is there a way to unit test a theme? is there a way unit test a framework (not a theme framework) that interacts with WordPress, that is, for example, can you write a unit test for dealing with the loop, dealing with the widgets?

* < (github mirror)

How to Add Rewrite Ruled Argument Into Permalink Properly

mysite.com/products/?type=foo&paged=2

WordPress mysqli and PDO
Does WordPress code base use mysqli or PDO?
I know PDO is superior to mysqli but mysqli is not bad neither. Plus from one of the features of what makes PDO is superior to mysqli ( that is being database agnostic ) does not mean much to WordPress as WordPress will always use mysql server. But binding params with data types is something PDO supports but mysqli does not and it's a good thing.
My guts tell me that WordPress does use mysqli but I could not see it in the code base yet.
My second question is if WordPress is using mysqli, is it because of speed concerns or is it because back in the earlier days (when WP was being developed), PDO wasn't just there yet? | WordPress uses `mysql_*` functions.
<
It has used those ever since I can remember, which probably answers your last question. It is what I would consider legacy code. I suspect it will be updated sometime soon (those functions were only deprecated as of PHP 5.5, I believe). I don't know which route development will go.

Pagination 404 errors for author posts query on author.php
I'm trying to query all posts by an author and paginate them on the author.php page. I've tried messing with the WP default blogs per page settings and that doesn't help.

'post_type' => 'post',
'author'=>$authorID,
'orderby'=> 'date',
'showposts'=>'5',
'paged'=>$paged
);
$query = new WP_Query( $args );
I even tried query_posts() with no luck.
The query itself works, but the pagination breaks. Any ideas? | There is already a query on that page. `author.php` is an optional template file that, if present, WordPress will use for author archives. You shouldn't have to create another query on that page. I think that your query and the native query are colliding, at least in part because both queries will be using the same `paged` query var.

Where is this strange og:description coming from?

them to potential site visitors. It might say s" />

I can't find that string anywhere in my WP admin settings, or in the "Facebook Open Graph Options" setting (as part of the "Facebook OpenGraph" plugin that I have installed). It's also not in any of my theme's template files, and it's not on my actual about page.
Where can I find this description, so I can change it?!

Get first category only and excluding one

$category = get_the_category();
if($category[0]->cat_name == "featured") {
//if first category in array is "featured", get next category in line
$name = $category[1]->cat_name;
$cat_id = get_cat_ID( $name );
$link = get_category_link( $cat_id );
echo '<a href="'. esc_url( $link ) .'"">'. $name .'</a>';
} else {
//get the first category
$name = $category[0]->cat_name;
$cat_id = get_cat_ID( $name );
$link = get_category_link( $cat_id );
echo '<a href="'. esc_url( $link ) .'"">'. $name .'</a>';
}
If you are outside the loop you can pass a post ID to `get_the_category($id);`

Custom post types problem
I have in my blog around 2k+ posts in 15 categories and around 1k tags. The problem now is that the website I bought the theme from decided to upgrade/update their themes infrastructure and now I need to export my normal posts into a custom post type. Ill explain below.

Reordering content using a meta value

How to add subscript and superscript in WordPress page titles
It is possible to add subscript and superscript in a WordPress page title? I need to add pages with "H2O" in the title.
I have been searching, but cannot find anything with answers... only a few non-answered threads on wordpress.org forums. | You can use markup in titles. `H<sub>2</sub>O` will work just fine. I would use H₂O with a real `₂` because markup will be stripped in title attributes and in feeds.
Note that WordPress will not create a pretty permalink for the correct character. The slug for my example will look like this: `h2o-h%e2%82%82o`.
You need my plugin Germanix URL to get `h2o` for both variants.

order of date column in custom post type
I have a custom post type and trying to set custom columns, the date column is there by default, and it appears right after the title. Do I have to unset the date first and then re-apply it, or is there a more elegant way of achieving this:
function custom_columns($columns) {
unset( $columns['date'] );
$columns = array_merge($columns, array(
'title' => 'Alert Title',
'region' => 'Region',
'date' => 'Date',
)
);
return $columns;
} | That's the only thing there is to do: _array manipulation_.
The filter `manage_edit-CPT_columns` is fired in **`class-wp-list-table.php`**:
add_filter( "manage_{$this->screen->id}_columns", array( &$this, 'get_columns' ), 0 );
Which in turn dispatches the function `get_columns()` in the sub-class **`class-wp-posts-list-table.php`**.
And, inside it, one filter for taxonomies, and others for _post/page/cpt_ columns.

Updating parent themes vs. updating starter theme
# Context:
I use framework parent themes (e.g. Thematic) mainly because it ensures that my custom themes inherit cutting-edge and standard compliant code.

Is my understanding of the process of updating starter themes correct and if so, is it not less work to simply **reverse engineer a parent theme once and have automated version** updates rather than **repeatedly manually (and perhaps tediously) having to update my custom starter theme**? | You can enable child themes for any theme:

Turning a WP Site Into an iPhone/iPad App
With the advent of responsive design, it's beginning to simply make sense that we could make a site into an app. The concept is simple:
* When the user is on the site, remove the browser around the site so that it appears to be like any other app
* Provide the appropriately-sized icons for devices (tablets, smartphones, etc.)
* Meet all criteria necessary to distribute the app via the Apple app store
I'm curious if anybody has the hacks, tutorial, or information necessary to achieve this. | The best way to do this would be to use CSS3 media quires: `@media (max-device-width: 480px)` but requires more work.
The quick and dirty way to make your WordPress theme app-like would be to add the viewport meta tag to the `<head>` of your page:
`<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> `
Viewport scales you page to fit the users device.
To hide the address bar in iOS and Android Just add this line of JavaScript to your page:
// When ready...
window.addEventListener("load",function() {
// Set a timeout...
setTimeout(function(){
// Hide the address bar!
window.scrollTo(0, 1);
}, 0);

So, not sure where the code would actually go...
Thanks in advance | Technically yes, you can add those lines to your header.php file just after the wp_head() function and it'll load the jQuery from a remote source, just like it was on your local machine.

Retrieve default permalink while using seo friendly URLs in WordPress

Why is WordPress saving full-urls to the database?

There are themes like Roots where there are functions like `roots_root_relative_url` using `preg_replace` to remove the full url.
Wouldn't it be better to only have relative urls, **what is the downsides of that?**

I am new to this particular stackexchange (I use stackoverflow often) and wordpress development, so forgive me if this seems like a stupid question. | If you don't want to give users access to the WordPress admin screens and you don't want to use a premium plugin, you should create a form in a page and use wp_insert_post with the submitted data.

subdirectory install breaking existing links

My question: Is this behaviour as designed, or am I doing something wrong?
Please note: My question is not how to fix it. It's easy enough to add some lines to the root `.htaccess` to say, "for every request inside `/wordpress/`, if it doesn't exist, remove the word `/wordpress/` and try again," so I'm surprised WordPress doesn't do that by itself.

”doing_wp_cron” in URL even if ALTERNATE CRON is not in wp-config
The insertion of `?doing_wp_cron` in Wordpress’s URL is very well documented here.
My problem is a little different. I turned on the `ALTERNATE_WP_CRON` feature in my `wp-config` file a few days ago. Then, noticing this issue –i.e. the introduction of `?doing_wp_cron` in my URLs– I disabled it. And by “disabled” I mean I completely removed it from the `wp-config` file. I did this 36 hours ago.
My problem is that `?doing_wp_cron` is still showing up in my access log. I wonder why? My two hypothesis are:
1) I should not remove `ALTERNATE_WP_CRON` but instead I should give it the value `FALSE`
2) Those URLs are in some browsers cache and being served as such. With time they should disappear.
Feedback will be appreciated.
P. | I have confirmed with my host that this is a normal occurrence in access logs when running WordPress crons. Also, since I disabled `ALTERNATE_WP_CRON` I didn’t come across any actual (live) URLs with the `?doing_wp_cron` attached to them. | stackexchange-wordpress | {

INSERT INTO wp_postmeta (post_id, meta_key, meta_value)
SELECT wp_posts.ID, 'category', 'photography'
FROM wp_posts
WHERE wp_posts.post_status = 'publish' | You can use WordPress functions to do this and just run it once, a fast example would be.
function wpse_85236_add_photo_field(){
global $post;
$photoquery = new WP_Query('posts_per_page=-1');
while ( $photoquery->have_posts() ) : $photoquery->the_post();
if ( in_category( 'photography' )) {
add_post_meta($post->ID, 'category', 'photography', true);
}
endwhile;
}
add_action( 'init', 'wpse_85236_add_photo_field' );
Remember to remove the function after it runs because you don't want it to run on every load. | stackexchange-wordpress | {

modifying the comment form
I see that there are lots of filters and things you can do to remove fields or modify them. I have found some useful ones on this site. I want to take it a step further because I want to do some things that there does not seem to be a filter for. Like removing the labels. At least I have not found one yet. I also need to remove the submit button and want to replace it with an actual button. For styling purposes. So I thought I could copy the comment_form function out of the wp-includes/comment-template.php file and put it in my functions.php file so that I could make any modifications I wanted. Problem with that is that WordPress throws you one of those previously declared functions errors. So I was looking for the filter or action to unregister that function so that I can use it in my functions.php file but I can't find it. Do you know how I can do this?
I tried
remove_action('comment_form');
but this did not work | That function is called directly in a theme, probably in `comments.php`. Remove the function call there, and use your own function with a different name.
Be aware many plugins rely on the code in the native function. If you change too much, some plugin might break.
You can edit the `label` element with a filter on `'comment_form_default_fields'`. Please do not remove them, they are important for screen reader users. | stackexchange-wordpress | {

Why WP_Query('showposts=5') shows only 1 post?
I am trying to do a simple query to get the latest 5 posts into an unordered list, but this is only showing 1 result even though I have several posts. I even did an offset, but it shows the next post yet still 1 result. What am I doing wrong?
<ul>
<?php $the_query = new WP_Query('showposts=5'); ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>
<li>
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a>
<p><?php the_content_limit(250); ?></p>
</li>
<?php endwhile;?>
</ul> | `the_content_limit` does not exist in WordPress. You probably want something like `the_excerpt`.
What's likely happening is your loop is working fine, but the call to an undefined function causes the program to error out, making it appear the the loop is not working. Look at the rendered HTML: you'll probably see a single, opening `<li>` tag, the link and an opening paragraph tag.
`showposts` is also deprecated. Take a look in the codex: dropped in 2.1
Try this:
<?php
$query = new WP_Query(array(
'posts_per_page' => 5,
));
while ($query->have_posts()): $query->the_post(); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<p><?php the_excerpt(); ?></p>

Do i need to keep register_post_type in functions.php?
I am creating several custom post types, do I need to keep the register_post_type calls in functions.php? I would assume that this would only need to be run the once then removed, or do I need to keep the calls there? | Yes, you need to keep it within `functions.php` and within the `init` hook, as it will have to register each time.

The $post variable – Did I get the grasp of how the Backend actions get parsed?
I was looking for a way to attach a custom meta box to the edit screen of a page at a specific template.
I found and tried this here and from my actual point of view this can't work that way. Let me explain why I think so: To determine, whether I'm on a screen using a specific template I need reference the global $post. But since this function to create the meta box is hooked into the admin_init the global $post will not yet exist.
So it has to put out an Error message, doesn't it? After those thoughts I tried to tie my meta_box_init function to edit_post, save_post and such. But the codex says, even they need $post to be set. So how could I achieve my page template specific meta box, really? Is there a clean solution? | As I've already wrote in question comments, at the very beginning of creating the new post or page first choose a template and save as draft. Meta box will appear after save if right template is used.
<?php
add_action( 'add_meta_boxes', 'my_add_meta_box' );
function my_add_meta_box() {
// get template file name
$template_basename = wp_basename( get_page_template() );
// check if right template is used
if('my-template.php' == $template_basename) {
add_meta_box(
'my_metabox',
__('Metabox name'),
'my_display_metabox',
'page',
'normal',
'high'
);
}
}
function my_display_metabox($post) {
wp_nonce_field( 'my_metabox', 'my_metabox_noncename' );

How to disable Jetpack modules such as Stats?

Move content between custom post types
I am importing a large amount of content from Expression Engine, the content in the other Expression Engine is all grouped together. I have created all the custom post types and taxonomies to organize the content better. However, Once I import the content to WordPress, I need to move the content into the newly created post types.
How do I move content from one custom post type to another? | The information about post type is stored in wp_posts table in DB in column post_type - either post, page, attachement and other post types you've defined. So i quess you can use some SQL query in your case.

How to get date of post when using wp_get_recent_posts()?
I get the latest posts this way:
$args = array( 'numberposts' => '2' );
$recent_posts = wp_get_recent_posts( $args );
Then I loop through them and get information about the post this way:
$recent_posts[0]["post_title"]
How can I get the date the post was published? | You can see everything returned via php's `var_dump` or `print_r`:
$recent_posts = wp_get_recent_posts();
echo '<pre>';
print_r( $recent_posts );
echo '</pre>';
This will reveal that the date is stored in `post_date`:
foreach( $recent_posts as $recent ):
echo $recent['post_date'];
endforeach;
Or to format the date, use php's `date` and `strtotime`:

Query by post title
I've used a custom post type for one of my website. Custom post type contains scratch card data along with some custom fields.
I've developed an android application to manage those items from android device.
In the android app, I want to keep search feature which will help admin users to search card numbers to manage those.
I can use wordpress query to search by title.
Code
$args = array("post_type" => "mytype", "name" => $title);
$query = get_posts( $args );
It can only provide result if I provide exact title. But I need to retrieve all items with similar title.
Any suggestion? | You can use either search parameter of wp_query :
Code
$args = array("post_type" => "mytype", "s" => $title);
$query = get_posts( $args );
Or you can get posts based on title throught wpdb class:
global $wpdb;
$myposts = $wpdb->get_results( $wpdb->prepare("SELECT * FROM $wpdb->posts WHERE post_title LIKE '%s'", '%'. $wpdb->esc_like( $title ) .'%') );
Than you'll get post object in this form:
foreach ( $myposts as $mypost )
{
$post = get_post( $mypost );

remove_menu_page breaks "Add media"
Using the the remove_menu_page function results in a really strange bug. By adding the code below in the functions.php file the integrated "Add media" widget starts to bug.
function remove_menu_pages() {
// Remove admin menu pages that are not used
remove_menu_page( 'link-manager.php' );
remove_menu_page( 'tools.php' );
}
add_action( 'admin_init', 'remove_menu_pages' );
When clicking "Add Media" while editing a post no files will show up under "Media Library", even tough the Media Library has plenty of files uploaded to it. If you try to upload a file, it will show up, but you won't be able to insert it into the WYSIWYG editor. If you close the "Add Media" window and then open it again the file is gone (but it's there if you navigate to the media library in the main navigation).
Have anyone experienced this? Can anyone replicate it?

How to move existing Wordpress wp-content folder along with database to new server and new domain name?
Running WP 3.5.1 on a LEMP stack (over at Linode) ...
I have a wp-content folder for a WP site along with a full backup of the database. The URL of the site was something like:
> test.example.com
I want to get the site operational on my own server at:
> test.mydomain.com
And once the site is finished and DNS changes take effect, I want to have the site URL be:
> myclientsdomain.com
What is the preferred (and hopefully most straightforward way) of handling server moves and domain changes like this? I'm looking for a step-by-step answer, one that accounts for all the situations described above for both the files and database. | There's a pretty good step by step on moving WordPress in the Codex. It is what I follow when changing domains.
Moving the files is pretty straight-forward. It is the hard-coded references in the database that are tricky. However, serialized search and replace will take care of all database changes.

Create hooks based on an array of hook names?
I have this idea where I would create a class that would take in a set of hook names then create them, for me to use when ever, and where ever.
Currently the way to create a hook is we do something like:
function some_hook_name(){
do_action('some_hook_name');
}
And then from there we write some other function, well call - add_content and then pass it to the action as such:
add_action('some_hook_name', 'add_content');
and there we go.
But what if I wanted to create a class where I do something like:
$array_of_hook_names = array(
'hook_one', 'hook_two', ...
)
so that later on, I could do:
add_action('hook_one', 'add_content');
Is there any way to do this? Could I just do something like:
public function setup_hooks($array){
foreach($array as $hook_name){
do_action($hook_name);
}
}
Ideas? | Your proposal is OK - you can see this in action even in the WordPress itself. See admin-ajax.php where you can find this piece of code:
// Register core Ajax calls.

add_action( 'wp_ajax_' . $_GET['action'], 'wp_ajax_' . str_replace( '-', '_', $_GET['action'] ), 1 );

Filter categories/tags to display in multiple metaboxes for selection in back-end
