Modify built-in post type properties
I have an unusual situation where I need to make the built-in post type 'page' non-hierarchical.
I printed the post type object with `var_dump(get_post_type_object('page')); die;` and I got this:
object(stdClass)#164 (26) {
["labels"]=>
...
}
["description"]=>
string(0) ""
["publicly_queryable"]=>
bool(false)
["exclude_from_search"]=>
bool(false)
["capability_type"]=>
string(4) "page"
["map_meta_cap"]=>
bool(true)
["_builtin"]=>
bool(true)
["_edit_link"]=>
string(16) "post.php?post=%d"
["hierarchical"]=>
bool(true)
....
}
How might I go about modifying the post-type object so that `["hierarchical"]=>bool(false)`? | This is a pretty late answer, but I was looking to do something similar and figured it out. I wanted to get nav_menu_items into an RSS feed, which required changing the built in nav_menu_item post type property publicly_queryable.
Anyway, it was actually pretty simple, here's a generic function to do it:
function change_wp_object() {
$object = get_post_type_object('post_type');
$object->property = true;
}
add_action('init','change_wp_object');
And that's it. I've got it in a plugin. If you want to see the list of available properties to change, throw in
echo '<pre>'.print_r($object, 1).'</pre>';
to get a nicely formatted output of all the properties.
In your case you'd use
$object-> hierarchical = false;

Optimizing wp_get_attachment_image_src
I'm working on WordPress gallery. I display images with wp_get_attachment_image_src function:
foreach($slideshow_data['attachment_ids'] as $attachment_id) {
$img_data = wp_get_attachment_image_src( $attachment_id, 'full' );
echo "<img src=\"{$img_data[0]}\" width=\"{$img_data[1]}\" height=\"{$img_data[2]}\">";
}
Which results in over 140 database queries per page for large galleries. Of course this can be cached, but I feel that this is not correct way.
My question is, am I doing something wrong?

Disable a Custom Taxonomies default save mechanism
I have a custom taxonomy X.
I've specified that the UI should be shown (for debugging purposes), however the UI is now interfering with my automation. I have code that automatically mirrors terms into this taxonomy, duplicating it. Taxonomy X is effectively a copy of Taxonomy Y or a subset. This code is working almost perfectly, except that my assignment code is doing its work which is then undone by the WordPress UI code setting the terms for the post from the metabox.
So how do I make the metabox showing Taxonomy X terms read only? AKA keep the metabox, but remove any save/edit/delete hooks attached to it?
_**edit:** for reference, if `show_ui` is set to false in the registration of the taxonomy, and the UI for that tax is hidden, then everything works as expected. ( which itself is to be expected)_ | Like Bainternet suggested - `remove_meta_box( 'tagsdiv-custom_taxonomy_id', 'post', 'side' );` to remove the default Metabox. If you want to still _see_ the terms. Then re-register the metabox with your own custom callback.
This callback function can then mimic the function used to display the default metabox - but simply omitting any input forms /checkboxes which send any data.
The function you'll want to mimic is:

Removing admin javascript
I'm having some trouble adding jquery-week-calendar to WordPress' admin interface using `add_menu_page` and other API methods. What I found out is that the default `jquery-ui` and other JavaScript references are interfering in the rendered calendar behavior.

if ( !array_key_exists($handle, $wp_scripts->registered) )

WordPress adding <br> tags into plugin content
We've written a plugin that shows reviews upon usage of a shortcode. On some sites, Wordpress is adding `<br>` tags throughout the shortcode content, and others it does not.

I would like to give special promotion for the first 100 posts in my blog? Can anyone tell me how to do that?
My website is a multi author blog. I would like to give special promotion for the first 100 published posts in my blog?

How to query for most viewed posts and show top 5

Is there a limit to the length/size of serialized data that can be stored as user meta?
I tried to store an array containing about 50000 keys and respective values to the user meta using update_user_meta. Since, this was only a test, I ran a for loop to generate the array.
$test = array ();
for ($i = 0; $i <= 50000; $i++) {
$test[$i] = $i;
}
update_user_meta($user_id, 'test', $test);
I ended up getting the error `WordPress database error: [MySQL server has gone away]`. Eventually, I was able to get it working with an array size of 48000 keys. Since update_user_meta converts arrays to serialized data before storing, is there a limit to the serialized data that user meta or post metas can handle? Or does this happen due to some other issue?
I tried the timeout fix suggested here. But I am not sure if it is supposed to work for WP 3.3.1. or whether if at all it is solution to my problem.
Please note I am using a local dev install using MAMP. | According to the DB schemea, the `meta_value` column is of type longtext, and that has a maximum size of 4GB, however you're unlikely to reach that.
Eitherway storing large quantities of data in a single field is bad both from a practical point of view, a performance point of view, and data storage.

Sadly WP can't output anything more than this. Every error output sends a header (as `var_dump`/`var_export`/`print_r`/`print`/`error`/`printf` would output.

Custom Post Type & Meta Box - Displaying meta box information on front end?
I've created a custom post type "projects" that has a meta box for additional information (client name, type of project, budget, etc). I'd like to be able to display this information on the front-end.
The custom post type is available to be added to custom menus if desired ('show_in_nav_menus' => true), but when you view each project, all you see is the title and the description.
Ideally, I'd like the meta data to show with the title and description in whatever theme that is being used for the site, but I don't know if that's possible.
Is there a way to display the meta box information on the front-end without having to either (a) touch the theme files (since themes can change so I don't want to do that) or (b) calling my own function that returns my own page template for the projects (because then it won't use the theme that is active)?

ETA - This is all done within my plugin. | Solution:

'post_status' => $post_type,

Hourly WP schedule, do I need at least 1 visitor hourly?
I am planning to schedule an hourly task from my wp plugin, as I understand these tasks are triggered by visits to the website.
So for an hourly task I will need at least one visitor hourly.
Does it matter at what time of the hour the visitor comes? For example if there's a visitor at 1:05, and another at 2:55, the 1 and 2hs task wont be missed? | As you've noted, cron jobs are only fired when someone visits your website. WordPress checks if they are any events that have been scheduled before 'now' that have not yet occurred - and runs them.
Importantly with events that are recur according to a regularly pattern (say hourly) - their occurrence is relative not absolute. That is, once your event triggers it will be scheduled again in an hour's time (rather than being schedule for 1:05, 2:05, 3:05) - of course with no guarantee that it will actually run in an hours time.
In fact with recurring events WordPress only keeps one occurrence saved. Once that occurrence is trigged it is replaced with the next one. | stackexchange-wordpress | {

Change Site Title and Description html tags if not home page
For the purpose of good HTML structure, accessibility and SEO I'd like to change the site's title and description from H1 and H2 to P when appearing on any page other than the homepage.

WP_Query with 2 genres
I'm working with a custom post type and trying to get a query working that includes 2 genres (a custom taxonomy).

array(
'post_type' => 'widgets',
'post__not_in' => array($wp_query->post->ID),

'post__not_in' => array($wp_query->post->ID),
'genre' => array('styleB', 'styleC')
)
);

Much appreciated. | Something along these lines should work:
$myposts = new WP_Query( array(

'taxonomy' => 'genre',
'field' => 'slug',
'terms' => array( 'styleA', 'styleB' )

function fb_change_fead_creator( $text ) {
if ( ! is_feed() )

Get moderation notifications on one post only
I'm running a web based community using wordpress multi-site and buddypress. All users are invited by existing users so no spam accounts exist on site. Therefore we feel no need to moderate logged in users.
Since doing this we have found that from now on all moderation requests come from spam attempts. So I have turned off email notifications for moderation.

3. I enabled comments on this new page, both in wordpress admin, and in the theme.

What's the proper way to find and remove duplicate images from posts and the media library?
I just exported a largish WP blog from MediaTemple to PHPFog.
I used the standard WordPress export and import plugins.
For some unknown reason all of my media assets have been duplicated. I now have twice as many images per post.
If an original file was called "Lot-44-Warrens.jpg" it now has a duplicate called "Lot-44-Warrens1.jpg" Both files are attached to the same post.

So my question is how do I remove said duplicates from the media library and from the posts?
I tried to search the media library with "*1.jpg", but it didn't work.

Aggregate multisite RSS and restrict certain content
As the title says, I've got a multi-site setup with 18 sites and would like to combine the RSS feeds from all sites into the root site's feed. The other feeds can still exists, that's not a problem. Additionally, I'd like a way in the admin (on page/post edit, perhaps), to exclude certain posts from the feeds.
In addition to a custom plugin containing all the specialty widgets and core function overrides, we're using a heavily customized theme as well. I'm using this code in my functions.php to pull all content types into RSS:
function custom_post_feeds($qv){
if (isset($qv['feed']))
$qv['post_type'] = get_post_types();
return $qv;
}
add_filter('request', 'custom_post_feeds');
Any ideas? | The bottom line is that you'll need to have all the post content in one place in order to be able to form it into a single feed. (Querying efficiently across 18 different post tables is more or less impossible.) My go-to method is to use the Sitewide Tags plugin < which allows you to designate a "tags" blog, where a copy of every post on your network will be saved.
You could set your main site as the "tags" blog, but it'll mean that you have to rig something up to keep the duplicated content out of your main feeds. (Such as a filter on guid, which the SWT plugin uses to point back to the original content.) Alternatively, you could just set up a separate "storage" blog for this purpose, and then point your RSS links to it (or `switch_to_blog()` in the context of your primary site). | stackexchange-wordpress | {

how to replace get_template_part('loop','tag') with explicit styled version?

It is a wrapper for `locate_template()`, which itself is just a wrapper for `include()`.
By calling `get_template_part( 'loop', 'tag' )`, you are telling WordPress to look for/include a file based on the following priority:
1. Child Theme `loop-tag.php`
2. Parent Theme `loop-tag.php`
3. Child Theme `loop.php`
4. Parent Theme `loop.php`
**If you need to modify the markup of the loop itself, then you simply need to modify the appropriate file, according to the above priority list - e.g.`loop-tag.php` in your Theme or Child Theme.**

How to add a class to meta box
When adding a metabox, i.e.:
add_meta_box(
'metabox_id',
'Metabox Title',
'my_metabox_callback',
'page',
'normal',
'low',
array( 'foo' => $var1, 'bar' => $var2)
);
how do I add a `class` to it for css styling? I'd like to avoid having to call each `id` in the style rule for metaboxes that contain elements having the same style. | Just add the class to the markup you are generating in the callback. | stackexchange-wordpress | {

How can I query the db to access current post information?
Alright y'all. I want to dynamically display the information of the 2 most current posts to the screen. So far I have only been able to get results by hard coding the ID into the query. Is there a way to retrieve this data dynamically?
query_posts('showposts=2');
while (have_posts()) : the_post(); ?>
<?php $x = get_the_ID();
echo $x;
$postStuff = $wpdb->get_row('select * from wp_posts where ID = "$x", ARRAY_A);
print_r($postStuff); ?>
<?php endwhile;?> | The correct way:
$my_query = new WP_Query('posts_per_page=2');

<?php
global $post;
print_r($post); // <-- this is your postStuff
?>
<?php endwhile;?>
<?php wp_reset_query(); ?>

Remove the Edit button in posts for permalinks on certain user roles? WP 3.3
I am using Wordpress 3.3.2 with the following plugin: \- <
The plugin works perfectly but the author said there is currently no way to achieve this from the plugin, So I am wondering if there is either another plugin or any code modifications I can make to achieve them.
1. I created a custom user role Called "Member"
2. I applied certain permissions so the user can only sees options to make posts in the backend.
3. When making a post, the user does not see the "Edit" option to change the permalink.
4. The problem comes after the user submits the Post. Right below the post title field it shows the permalink and shows an "Edit" button which allows the user to change the permalink.
Is there any way to remove either the "Edit" button so they can't edit the permalink, or removing that entire line altogether so the permalink doesn't show for them at all?
Thank you in advance! | You could do something like (in your functions.php file);

$post = get_post( $id );

Displaying wp menus by name without using theme locations
I used wp menus in the past but always registering a location and then using:
<?php wp_nav_menu( array( 'theme_location' => 'header-menu' ) ); ?>
To display a menu on that location on my theme I would first create a menu, and then assign it to that location.
Well now what I would like to do is to create all the menus I want using some standard name like my-menu-1, my-menu-2, my-menu-x. And then I want to display those menus on my theme but without using any location, just printing them using code identifying them by name.
**How could I do that?** | Umm u can do that easily. And this is the way I do
how i register my menu in functions.php

function register_custom_menu() {
register_nav_menu('custom_menu', __('Custom Menu'));
}
Then in ur admin panel u create different menu by ur desired name. And get the menu where ever u want like this. EX:- if I made two menu in admin by name "Menu 1" and "Menu 2"

Wordpress adding in anchor elements when I save a page in html editor
This page I am editing in the html editor. I pasted in my list from my text editor. You'll notice that the second last list item is all a link, thats because wordpress has taken it upon itself to wrap the whole thing in an empty tag! Why is it doing this and more importantly, how do I stop it?

Unregister Nav Menu from Child-Theme
I like to use the Starkers Theme and build child-theme.
So, I`d like to remove the this primary menu
Starkers (functions.php)
function starkers_setup() {
// This theme uses wp_nav_menu() in one location.
register_nav_menus( array(
'primary' => __( 'Primary Navigation', 'starkers' ),
) );
}
endif;

unregister_nav_menu( array(
'primary' => __( 'Primary Navigation', 'starkers' ),
));
// my new nav
register_nav_menus(array(
'primary_navigation' => __('Main', 'starkers'),
'utility_navigation' => __('Meta', 'starkers')
));
But it doesn´t work for me.
What´s wrong?
Thanks | The Starkers theme setup is hooked to `after_setup_theme`, at a priority of `10`. So you basically have to wrap the unregister function inside another function (child themes functions.php file) and add it _later_ than the parent themes setup function, so it gets first added by the parent and later on removed by the child.
function wpse_remove_parent_theme_locations()
{
// @link
unregister_nav_menu( 'primary' );

Best Way to Query Custom Taxonomies Used on Custom Post Type
I have a custom post type and a custom taxonomy located in a plugin. In writing my output loop for the CPT, I'm trying to output all the custom tax items assigned to the CPT items at the top of the page before outputting each individual CPT item.
This is what I'm hoping to achieve:
tax 1 | tax 2 | tax 3 | tax 4 ...
CPT 1
CPT 2
CPT 3
...
I assume `wp_get_object_terms()` is the best way to get at the tax items, but I have to pass in the `$post->ID` or, in my case, an array of ID's as a parameter.
Is there a way to write only 1 loop which would grab the IDs, do its thing and them move on to output the CPT items, or do I have to write 2 loops, 1 which first builds the array of CPT post ID's to pass into the function and then a 2nd which outputs the CPT items? Am I missing something else entirely?
Thanks for your help! | Yes there is a way using only one loop but that can be messy and have on resources for large amounts of data,
To do that you simple store all of the output as a variable and only output after you finished your loop, ex:
$tax_array = array();
$output = '';
while ( have_posts()) {
the_post();
$output .= '<div class="item">';
$output .= '<div class="item_title">'.get_the_title().'</div>';
$output .= '<div class="item_content">'.get_the_content().'</div>';
$output .= '</div>';
$temp = wp_get_object_terms($post->ID,'tax_name');
$tax_array = array_merge($tax_array,(array)$temp);
}
so after this single loop you have all of the items output in `$output` and `$tax_array` holds an array of all terms that you need. | stackexchange-wordpress | {

why does WordPress need two cookies for auth/login
I can see two cookies: auth and login cookies in wordpress. Why do we need two? I think one is enough. | "On login, wordpress uses the wordpress_[hash] cookie to store your authentication details. It's use is limited to the admin console area, /wp-admin/
After login, wordpress sets the wordpress_logged_in_[hash] cookie, which indicates when you're logged in, and who you are, for most interface use.
Wordpress also sets a few wp-settings-{time}-[UID] cookies. The number on the end is your individual user ID from the users database table. This is used to customize your view of admin interface, and possibly also the main site interface."

Single-page wordpress theme navigation

I thought I will use `query_posts` for `'post_type' => 'page'` and just style those pages but is there more flexible way of doing this? Also this query displays all pages (all I want is just depth = 1) and I don't know how to order them same way as wp_list_pages does.
Maybe there is some text to read about this kind of pages on the internet? | I've done a few templates that essentially are on one page. I used this code as the starting block for all of them:
<?php
$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page','posts_per_page' => -1));
foreach ($all_wp_pages as $value){
$post = get_page($value);
$slug = $post->post_name;
$title = $post->post_title;
$content = apply_filters('the_content', $post->post_content);
};
?>
It basically gets every page, you can then use the variables to build the rendered markup.
Then a small change to meet you're depth requirement I would use:
`$all_wp_pages = $my_wp_query->query(array('post_type' => 'page','depth' => 1, 'posts_per_page' => -1));`
And finally `'posts_per_page' => -1` gets everypage, not limited to the number set in 'Admin > Settings > Reading'

Get the post_id of a new post
There are several ways to get the id of a post after it has been saved (auto, etc.), but is there a way to get the post id immediately after you create a new post?

thoughts?
cheers! bo | Try this...

Passing variables to templates (alternatives to globalizing variables)
I want to make my WP code simpler (there's some mess within header.php, page.php etc.). So, for example, I want to set something like this global:

So `$foo` will work properly used anywhere in page.php, header.php, footer.php, loop.php and also within different theme files linked to functions.php (require_once).
I already know two ways of achieving this, both require editing functions.php:
## Global dynamic function
function foo() {
return 'bar';
}
## Global constant
define('FOO_BAR', 'directory');
Do I really need to fire a function in multiple places just for one variable? Isn't it an overkill? | You could also use this function:
set_query_var('foo', $foo);

The purpose of the post_date_gmt?

Switching theme only changes style sheet being used
I have a plugin that I'm using to switch themes for a specific user for development. When logged in as that user they see the different style sheet but the themes files, function.php, header.php, etc are the active theme for everyone else.
What I am doing wrong?
function change_user_theme($template) {
global $user_ID;
if ( in_array( $user_ID, array( 5 ) ) ) {
$template = 'fezmobile';
} else {
$template = 'fezforprez';
}
return $template;
}
add_filter('template', 'change_user_theme');
add_filter('stylesheet', 'change_user_theme');
add_filter('option_template', 'change_user_theme');
add_filter('option_stylesheet', 'change_user_theme'); | Take a look at my answer here:
Switch Theme Through Options Panel
The code is as follows:
add_action( 'setup_theme', 'switch_user_theme' );
function switch_user_theme() {
if ( in_array( wp_get_current_user()->ID, array( 5 ) ) ) {
$user_theme = 'fezforprez';
add_filter( 'template', create_function( '$t', 'return "' . $user_theme . '";' ) );
add_filter( 'stylesheet', create_function( '$s', 'return "' . $user_theme . '";' ) );

}

Using default wordcount javascript in Wordpress on custom wp_editor() areas
I have two `wp_editor()` instances on pages and posts used to populate the sidebars of my three-column website. I would like to use the default wordpress word-count script on the two wp-editor areas to get the word-count of the content within them.
I enqueued the script and added the required HTML but the wordcount was always that of the main content editor area.
Has anyone managed to use this functionality with custom wp_editor areas and what HTML will I use?
I have searched on the web but could not find any examples where the default script is used.
Thanks in advance nav | Git this to work by using the following line of code in my theme's functions.php.
$wordcount = str_word_count( strip_tags( $content ), 0 );
I got this piece of code from a stackoverflow post.
The only disadvantage with this code is that it does not update dynamically which is not a big issue as the current wordcount will show up every time the post is updated.
The problem with using javascript on which event I should trigger the wordpress function on.
WordPress's wordcount functionality is tightly coupled with the default editor and I had to duplicate their javascript to try and get similar functionality which is not a good choice.
I would still like to get some thoughts on this by a more experienced WP developer.
Thank you. nav | stackexchange-wordpress | {

LESS compiler for Wordpress

Thanks Ogni | Alternative see the lessphp Project: <

difference between add_options and register_setting
I am confused. Want to save data for my plugin. There are people who use add_options and there are others who use register_settings. My question is What is difference between `add_options` and `register_setting`? | register_setting() uses Settings API, which is just an API for options.php, is easier to use, more secure and preffered way of storing options since WordPress 2.7.
If you need to store only a few options or doing simple plugin just for yourself - it's really up to you which one to use :)
Here's the Settings API (well) explained: <
Basically it makes a few things much easier, you don't have to render whole forms all over again (great for plugins/themes with many options), you don't need to care about nonces etc.

Display a custom taxonomy as a dropdown on the edit posts page
When you create a custom taxonomy, seemingly the only options are to display it as a tag (non-hierarchical) or category (hierarchical). Is there a way to display them as a dropdown menu?
I realise that this an be done using `add_meta_box()` and actually manually adding it, but I'm looking for a builtin way (if one exists), to save lots of code! Thanks. | Unfortunately there is no way of doing this with `wp_register_taxonomy()`. When you register a taxonomy, the default metabox is either checkboxes (hierarchical) or as a cloud (non-hierarchical).
The only way round it is to de-register the existing metabox and add a new-one in its place. By carefully mimicking the 'default' metabox - you won't have to process the data yourself, but let WordPress automatically handle adding / removing terms.
The details of how to do this are given in this answer. You may also find this GitHub repository helpful (which now includes the ability of creating terms on the fly in the new metabox). The linked resources refer to creating a metabox with radio boxes, but it could be easily adapted for drop-down menus. | stackexchange-wordpress | {

Image Upload from URL
I really like the way SE uploads an image from a URL (I'm sure many do!). I've been searching, but can't find, **is there a plugin or a method similar to this available for WordPress?**
I know an image can be uploaded and crunched directly from a URL by entering the image URL into the File Name box after you click Upload/Insert Media >> From Computer >> Choose File

Is there a PressThis that doesn't hotlink?
What are some plugins or alternatives to the PressThis function?
I want to use the PressThis bookmarklet to quickly blog about what I see online, but every time I do and include an image, it hotlinks to the image from the site I'm blogging about.
That's bad, because I don't want to tax the site I'm writing about. I don't want to use a full-sized image. And I don't want the image to be broken on my site if the site I'm writing about to goes down. | PressThis bookmarklet does upload images to the wp uploads folder that you add to the article. Basically in the PressThis window go to the 'Add' menu and click on 'Insert an Image' icon.

As well there's an empty Description field and just above that field - on the right click on 'Insert Image' and it will insert it in your post.

can't upgrade wordpress or install plugins, it seems to "think" it's still on a local installation

Query specific posts from parent by slug rather ID
I'm developing a theme in a local machine and migrating it to a production server. To keep things in sync, i'm trying to avoid any queries of specific ID's
