Search returns everything if search term has a space
When I try to search for terms with spaces, such as "lord of the rings", it returns all of my posts. However, if I just type "lord", it returns results.
Any ideas what would be causing this? | Chances are it's searching using the 'OR' operand, which for will pull up everything that has those common words - 'of the'.

Plugin Recommendation: Slideshow Gallery Delayed Image Loadging
I am wondering if there is a WordPress plugin that creates a slideshow of images where:
*flash isn't used
*images are not all loaded at once and instead are loaded after page load
I have a requirement for numerous images to be present in a slideshow that are high res. All images need to be stored locally (e.g. no flickr).
I took a cruise through one or two plugins but they include all the images at once. Which murders page load times.
Any suggestions? | I ended up using Really Simple Slideshow and manually integrating it into WordPress. Here is a link if this helps anyone:

Check if post has specific tag_ID in custom post type
I am using Event Manager and they have a custom post type of events, with a taxonomy of event-categories (separate from regular post categories). In that taxonomy I have created terms(?) or event categories, "Education" and "Research". I want a specific `<div>` to show up if a post is in the event-categories taxonomy with the term/category of "Education". The slug is "education" and the tag_ID is 8. Currently I'm trying to use this code snippet, but I'm not getting it. I know there's more to it, but I haven't been successful with other tutorials. Most are for category archives. I need it conditionally for single posts.
<?php
if(in_category('education')) {
echo '<div>test</div>';
}
?> | `in_category()` is conditional tag for taxonomy 'category'. With custom taxonomies you should use `has_term()` conditional, first parameter is term to check for and second is taxonomy.

Multisite Plugin - Access options (wp_options) on child sites
Is there a way I can access the `wp_options` table of all the child sites? I want to create a multisite plugin that can be setup at the network level and will populate the child site plugins with defaults that can then be overwritten by the each individual site. I'm aware that I could read/write from `wp_sitemeta` this way, but in my instance, it would make sense if I could access the other "local" tables. I could probably write a custom query using the WP query function, but I was wondering if there was a better way? | Try `get_blog_option()`.

Date not appearing in custom query
I'm having a weird issue with Wordpress which I cannot solve by myself, and for which I couldn't find an aswer over this and other websites.
Basically, I have a custom loop.
while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_post_thumbnail('featured'); ?></a>

<div class="dateonly"><?php the_date('d.m.Y'); ?></div>
<div class="titleonly"><?php the_title(); ?></div>
</div>
<?php endwhile; ?>

Should I use the standard wp_mail() function for a premium theme?
I am creating a premium theme that includes a Contact page template. Currently, I am using the `wp_mail()` function to send the contact email to the administrator-specified email address.
Basically, I am wondering if the `wp_mail()` function is the best/expected choice for implementing email functionality in a premium WordPress theme? If it is not, what would be the better option? | Yes, you should use `wp_mail()`. There is no difference between a premium theme and a regular theme in this point. `wp_mail()` has many advantages and your clients will rely on it. If you break it, many plugins will not work anymore.
Besides that, it is not the job of a _theme_ to change this functionality. There are plugins to replace the function. | stackexchange-wordpress | {

How can I remove the site URL from enqueued scripts and styles?
I'm dealing with an SSL issue and I would like to strip the domain from all scripts and styles being output via wp_enqueue_scripts. This would result in all scripts and styles being displayed with a relative path from the domain root.
I imagine there is a hook that I can use to fileter this, however, I am not sure which one, nor how to go about it. | Similar to Wyck's answer, but using str_replace instead of regex.
`script_loader_src` and `style_loader_src` are the hooks you want.

{
if( is_admin() ) return $url;
return str_replace( site_url(), '', $url );

You could also start the script/style URLs with a double slash `//` (a "network path reference"). Which might be safer (?): still has the full path, but uses the scheme/protocol of the current page.
<?php
add_filter( 'script_loader_src', 'wpse47206_src' );
add_filter( 'style_loader_src', 'wpse47206_src' );

How can I define the RSS feed content length?
I’m trying to shorten the content of my RSS feed. Right now it displays way, way too much for each entry and I’ve tried to select the “Excerpt” in the Syndications setting in my option panel but it hasn’t done anything.
I’ve tried different approaches but little has it helped.
Is there a simple way (possible add_filter) where I can set the RSS feed content length to, say, 200?
Thanks
\- Mestika | I usualy make a RSS feed in my template. Just copy the RSS feed you have in the wp-include/feed-rss2.php
Step two is registering it instead of the original:
// override feeds
function own_rss( $for_comments ) {
//it is in my theme/feed/rss2.php
$rss_template = get_stylesheet_directory() . '/feed/rss2.php';
if( file_exists( $rss_template ) ) {
load_template( $rss_template );
} else {
do_feed_rss2( $for_comments ); // Call default function
}
}
remove_all_actions( 'do_feed_rss2' );
add_action( 'do_feed_rss2', 'own_rss', 10, 1 );

How to check user's password?
I am trying to check the passwords of users I created on my WP multisite, but the ones I find in the `sw_users` / `user_pass` do not match what I get when I do a _MD5 hash_ of the passwords I received during the user signup process.
Here is an example from the table `sw_users`:
(11, 'user5', '$P$BiwskWiaqZIQLzDUTAhSyvACr0Jpnl.', 'user5', '[email protected]', '', '2012-03-28 11:44:08', '', 0, 'user5', 0, 0),
so I would assume that
> $P$BiwskWiaqZIQLzDUTAhSyvACr0Jpnl.
is the result of MD5 hash of the password. Is this correct? And why can I not match this when I run MD5 to the given password which is either
> EJnltoRrQC6K
or
> fnxIwBW9Sjrm | Wordpress does not just MD5 hash the password, it runs it through `wp_hash_password()` which in turn runs through the `$wp_hasher` (a global object) `HashPassword` method. This does some hsld crap to include getting random bytes of data, salting the password, and encrypting it.

Detect category choice for posts with multiple categories

Its essential that I use the route they chose, i.e. if they clicked Category 1, then Post A, if Post A is also Categorised as Category 2 and Category 3, I only want to show posts from Category 1 because that is what they originally chose.
Is this an option? Is there a way to store some sort of global variable which I can set on my category page, then utilise on my single page? | Use:
get_query_var('category-name');
Which will give you:
> example.com/ **category/subcategory** /my_post
Which you can then put into any queries you make under `category-name`.

Google Apps login in wordpress

why doesnt is_home() work in functions.php

wp_register_script('homepage', get_template_directory_uri() . '/js/homepage.js', 'cycle');
wp_enqueue_script('homepage');
}
add_action('wp_enqueue_scripts', 'my_scripts_method');
} | At the time _functions.php_ is included during bootup, WordPress has no idea on the contents of the query, and doesn't know the nature of the page. `is_home` will return false.
Wrap the code in a function and have it triggered by the `wp` hook, which comes after the global query object has been hydrated with data.
add_action( 'wp', 'wpse47305_check_home' );
function wpse47305_check_home() {
if ( is_home() )
add_action( 'wp_enqueue_scripts', 'my_scripts' );

How to generate video out of images via Wordpress plugin

require("wp-load.php");
$page_id = 300;
$data = get_page($page_id);
echo $data->the_content;
However, the content is different from what WordPress would output normally. For example, paragraphs which are separated by blank lines in source come just like that, without `<p>` tags. How can I get the content from a page in the same way that WordPress would print it? Should I apply some other filter or use another function to process the text? | Indeed! It's a filter called 'the_content', to which numerous other functions are hooked such as the one that turns Wordpress into WordPress, oembeds, and the p tag wrapping

Pods cms and "advanced custom fields" plugin
We are planning to build a quite big database to store data for our 5000 yearly subscribers association.
We were considering pods cms for our needs since it permits a good flexibility in building a complex website and is performance aware while managing the database.
But recently I red on the pods cms website that they're having some funding problems, so they're struggling reaching the 2.0 milestone.
We're afraid that the development could stop.
On the other side we found "advanced custom fields" that also seems a good alternative. Furthermore it has a stronger business model.
So what would you suggest me to do? | Development of Pods 2.0 definitely won't stop, the funding problems explained in that dev post were alluding to an upcoming announcement that we'll be pushing some of the enterprise and "extra" functionality of Pods 2.0 into a premium version targeted towards firms with more advanced and specific needs.
On the data structure, Pods 2.0 handles post types, taxonomies, and more. It even will have a migration feature to move between different content types. You probably won't be worse off by going with ACF right now, and eventually having to migrate to Pods, as you'll have a solution that works well for you when you need it (now).
Even if you don't use Pods, good luck with your project and I'm sure people would love to see the site you're working on when it's done if you find time to follow up with how it all worked out for you. | stackexchange-wordpress | {

How can I remove "Proudly powered by WordPress" from twentyeleven without modifying footer.php?
How can I remove "Proudly powered by WordPress" from twentyeleven without modifying footer.php, and without creating a child theme?
I'm looking for a php command, such as `add_action`, `remove_action`, `add_filter`, or something of that sort.
I'm not looking for CSS to hide the footer.
I don't want to modify any of the theme files other than `functions.php`
Is this possible? For reference the code in the footer that is creating this is below.
<div id="site-generator">
<?php do_action( 'twentyeleven_credits' ); ?>
<a href="<?php echo esc_url( __( ' 'twentyeleven' ) ); ?>"
title="<?php esc_attr_e( 'Semantic Personal Publishing Platform', 'twentyeleven' ); ?>"
rel="generator">
<?php printf( __( 'Proudly powered by %s', 'twentyeleven' ), 'WordPress' ); ?></a>
</div> | There are 3 methods.
1. Somewhat weird but since this text is internationalized you can filter the output. This is just an example to remove the text, the link is still present in the source.
add_filter('gettext', 'remove_powered_by', 20, 3);
function remove_powered_by( $translated_text, $untranslated_text, $domain ) {
$custom_field_text = 'Proudly powered by %s';
if ( !is_admin() && $untranslated_text === $custom_field_text ) {
return '';
}
return $translated_text;
}
2. Use jQuery (or javascript)
`$('#site-generator').remove();`
3. Create a child theme and just comment out the code or delete it. | stackexchange-wordpress | {

Is there a way to show different source feeds on individual pages?
As a freelance writer, I have a few outlets I write for routinely plus additional sites, and while I used to post my content manually, due to SEO concerns and logistical issues, I have been looking to modify my Wordpress install to pull posts of mine from my client websites and display the content as it is added.
I'm not sure if this is a valid comparison, but essentially I want to use Wordpress like Mahara which seems to be built for you to post all types of content, like a digital potfolo, all in one place.

Incremental number handling on duplicate file names
After a couple of hours searching the WP core I've lost hope finding this myself (for once).
Could someone guide me perhaps to where WordPress handles the incremental number when having duplicate file names during uploading?
As a side question. When handling questions like this, where and how would you start searching? AFAIK I've searched through every file containing `file` and `upload`. | The number is added in `wp_unique_filename()` in `wp-includes/functions.php`. You can prevent it by hooking into `'sanitize_file_name'` and setting another file name.
You can find such functions and filters by following the code with your IDE. Most IDEs make functions clickable so you can go from their call to their declaration.

Wordpress 3.3.1 Page template not showing in admin area

$params = array() // set parameters

update_post_meta( $post_id, 'mycoderan', true );
} | The `{$old_status}_to_{$new_status}` and `{$new_status}_{$post->post_type}` hooks tend to generally solve the problem.
To avoid running the code in case post status is changed to draft then published again (after already being published), implement a simple flag using the `post_meta` functionality.

display metabox on front end (my-metabox-class)

$my_meta->addRepeaterBlock($prefix.'re_',array('inline' => true, 'name' => 'This is a Repeater Block','fields' => $repeater_fields));

$title = get_post_meta(get_the_ID(),'mt_t_field_id',true);
echo $title;
Any advice? | Nice to see people using my class :)
Anyway when you save a field in a repeater block , to access the data you need to use the repeater ID which in your case it's
$repeater_data = get_post_meta(get_the_ID(),$prefix.'re_',true);
and this returns an array of arrays with the id as key and value as value so you can loop over the array like this:
foreach($repeater_data as $arr){
echo 'title: ' . $arr[$prefix.'t_field_id'];
echo '<br />Description: ' . $arr[$prefix.'d_field_id'];
echo '<br />Price: ' . $arr[$prefix.'p_field_id'];
echo '<br />image: <img src="' . $arr[$prefix.'i_field_id']['url']">';

Static Front Page problem
My theme uses the front-page.php file to display a number of items on the front page including a slideshow and some featured items.

Can anyone suggest anything that might help me.

1. The static page to serve as the Placeholder for your site front page
2. The static page to hold the content you want to display as an excerpt on the front page

(If this is a distributed Theme, then you'll want to add a Theme option or other means by which to select the Page ID to query in `front-page.php`; otherwise, you can just make the ID static, hard-coded in the template file.) | stackexchange-wordpress | {

Using pre_get_posts to set posts per page, how do I?

endif;
}//end filter_press_tax
I'm not quite understanding how to access the taxonomy and term in the $query. Yes the taxonomy and term have the same name. Is this a bad idea? I do not have a custom query set up on the taxonomy-press-press.php template for the 'tax_query' is this the problem?

if( $query->is_tax('press') && $query->has_term('press')):
$query->set('posts_per_page', 5);
return;
endif;
}
?>
You can use any conditional tag or any argument that can be passed to `WP_Query` to test your condition or set a new value via `pre_get_posts`. Also try `$query->get('taxonomy')` / `$query->get('term')`. And check this for `$query`'s set and get methods. | stackexchange-wordpress | {

`register_widget()` was introduced with the new Widgets API and takes an object/class as an input rather than actual widget parameters. WordPress can instantiate as many copies of this widget as you need, allowing you to have several instances of the exact same widget.

}
add_action('do_feed_rss2', 'create_my_custom_feed', 10, 1);

**Edit by Otto** : While that will work, this would be a better way:
function create_my_custom_feed() {
load_template( TEMPLATEPATH . '/feed-rss2.php');
}
add_feed('rss2', 'create_my_custom_feed');
The `add_feed()` function is smart, and will handle the actions and such for you.

How do I flush the rules after saving settings using the Settings API?
I'm using the Settings API to allow the user to toggle the `has_archive` option on some custom post types. When the user turns archives on or off, I want to flush the rewrite rules. If I had written the saving function myself, I could just call `flush_rewrite_rules()` and be done with it, but the Settings API takes care of the saving for me. Is there a hook somewhere that I can use?
## Chosen Solution @Stephen Harris
add_action('admin_init', 'my_plugin_register_settings');
function my_plugin_register_settings() {
if (delete_transient('my_plugin_flush_rules')) flush_rewrite_rules();
register_setting('my_plugin', 'my_plugin_settings', 'my_plugin_sanitize');
// add_settings_section(), add_settings_field(),...
}
function my_plugin_sanitize($input) {
set_transient('my_plugin_flush_rules', true);
return $input;
} | You simply need to visit the Settings > Permalink page (you don't have to do anything there) after saving the settings.
> If I had written the saving function myself, I could just call flush_rewrite_rules()
Not quite. `flush_rewrite_rules()` would have to be called after the custom post type is 'updated' to reflect the changes, that is, after you register it. So you would need to call it on the next page load, after the CPT is registered.
You _could_ use a transient to trigger flush_rewrite_rules() on the next ( **and _only_ the next**) `init` (and after CPT is registered). To be clear, `flush_rewrite_rules()` is expensive and shouldn't be called regularly, this is why I suggest simply telling your plug-in users to visit the Settings > Permalink page after altering any permalink options - that way the rules get flushed only when its really needed. | stackexchange-wordpress | {

Cleanest Way to Select Every Second Element in a Loop?

What is the best way to provide plugin users with a way to customized the styles
I'm working on a plugin to be release to the public, it is a very simple plugin that includes a single html element in the page html. I can do many things to allow users customize its appearance: 1\. Let them override a default CSS that is includes as a plugin configuration (on a management screen) 2\. Require that they modify their styles.css (not a very good idea for this plugin) And probably a fee more
option 1 seems like the most user Friendly, since it allows any admin to modify the style without need of accessing code. But I wonder if there might be a better way?
Is it possible to provide a default CSS file for the plugin that would be theme independent and would be editable through a management screen? The styling needs to persist regardless of chosen theme.
Any thoughts? | Is it possible? Yes.
# Option 1
Simply register and enqueue your default stylesheet. The theme stylesheet can then be used to override whatever styles you implemented.
function register_my_styles() {
wp_register_style( 'default-style', plugins_url('default.css', __FILE__) );
wp_enqueue_style( 'default-style' );
}
add_action( 'wp_enqueue_scripts', 'register_my_styles' );
# Option 2
Register whatever custom options you need either on a specific plugin options page or using the WordPress Settings API. Then output these styles in a regular old script block in the theme header.
function output_custom_scripts() {
?><style type="text/css">
<?php echo get_option( 'custom_css' ); ?>
</style><?php
}

What is the etiquette on extending a plug-in
I recently played with a plugin which I liked a lot, but felt it was missing something. So as first stage I went and wrote a tiny plugin (my first), that just added the needed feature - meaning, that the original plugin still had to be installed for something to work.
Now I gave credit to the authors for doing most of the job, but I have to think of the future, what happens if they decided to stop developing that plugin or don't resolve issues regarding it. My plugin will stop working or will potentially become incompatible with future Wordpress versions.
Would it be ethical for me to just avoid the issue alltogether by copying their code into mine and renaming the plugin functions? This of course causes other problems, but now they are my problem to resolve. What say you? | I'm assuming for now that the plugin is open source. If so ...
# Send them an update
Most devs appreciate contributions from the community. Contact the original authors and offer your code as a patch to add your new feature.
# Reference the plugin
Optionally, you can just hope that they keep developing the system and offer your smaller plugin as an extension. Just be sure to keep it up-to-date with a list of compatible WP versions _and_ the 3rd party plugin versions.
# Fork
Open source software is meant to be extended, adapted, and distributed. You have the right under most OS licenses to edit and redistribute the software so long as you follow a certain set of rules (i.e. maintaining original copyrights, releasing under a compatible license). I can't speak to specifics without knowing _which_ plugin you're using, but in the majority of cases forking the plugin and releasing your own version is 100% acceptable. | stackexchange-wordpress | {

highlight specific text in the content box
This is an idea that came through my mind, and I would like to know if possible and how to approach it if so...
I have my own wordpress framework that I use as based for all my projects, I manage the content position generated in the content box using shortcodes which respond to an especific div with a location...
Said this, sometimes I find myself into a mess really hard to understand, for sample:
[one_column] content [/one_column] [one_column] content [/one_column] [one_column] content [/one_column] [one_column] content [/one_column]
when the among of text is big, is hard to find where the shortcodes are placed.
So, is there any way to highlight the shortcode (like with a different color) into the content box? or maybe easier, is there any way to indent the content and keep that indent once I save or update the post?
I would like to hear you opinion,
Thanks in advanced.

How should I best target dynamically served content?
I am editing the 'Bizz' portfolio Wordpress theme( It includes custom post types for managing portfolio examples, the highlights on the homepage, etc.
I want to style the background color displayed behind each 'highlights' heading with a different color, but since they're served dynamically, I'm not sure how I should target each h2.
Would it be best to attach a unique class to each of the three headings through the php, or try to target them through CSS selectors? And how would I best do that?
My major concern in using CSS selectors would be backward compatibility, I dont know that I want to bulk up the page with extra bootstraps.
How should I go about it? Thanks! | I think it depends on whether you want it to be unique for each of the four "highlighted" project columns on the homepage, or whether you want each "highlighted project" to be different.
Does that make sense?
E.g. if you just want each of the four project "columns" on the homepage to look different then I'd use CSS to achieve this : nth-of-type perhaps.
But if you wanted Project A (when highlighted on the homepage) to have a unique background colour regardless of what column it appears in, then Id use PHP to add the post->ID as a class in addition to portfolio-item and then use CSS to style that. | stackexchange-wordpress | {

Remove action from shortcode
There is add_action() function inside function which is callback for add_shortcode(). Any idea how to remove this action with the help of custom plugin? Should I hook to any action which is called later then add_shortcode() function? I do not want to removing and re-adding shortcode, because there is huge function beyond it.
Simple example:
function test_shortcode() {
... other code ...
add_action( 'some_hook', 'custom_function');
... other code ...
}
add_action( 'wp_head', 'setup_theme' );
function setup_theme() {
... other code...
add_shortcode( 'test', 'test_shortcode' );
... other code ...
}
I need to remove custom_function() from this shortcode.
Thank you for your help... | OK, I found a way. Function add_shortcode is called for the_content filter with priority 11 (after wpautop). So, to remove custom_function() has to be done with the help of this filter (also with priority 11). Solution?
add_filter( 'the_content', 'unhook_custom_function', 11 );
function unhook_custom_function( $content ) {
remove_action( 'some_hook', 'custom_function' );

Managing Backups: Space Issues
I recently reached 95% full storage on my GMail. Approximately 60% of this was, in fact, email backups from Wordpress' "WP-DB-Backup" plugin on 10+ sites that I manage. (I get a scheduled daily backup of the whole database.)
There must be a better way to manage my backups. Ideally, if I can somehow automatically delete all but the most recent backup (whatever the solution is), that would be best. Sure, I can manually do this in GMail, but it's tedious and error-prone.
Is there a better way to do this, or a better way to manage WP backups without worrying about HD space? GMail doesn't look like it's a good solution. | You can use a plugin like **`backwpup`** that lets you:
* Store backup to Folder
* Store backup to FTP Server
* Store backup to Amazon S3
* Store backup to Google Storage
* Store backup to Microsoft Azure (Blob)
* Store backup to RackSpaceCloud
* Store backup to DropBox **(free)**
* Store backup to SugarSync **(free)**
and manage the number of backup copies to store which means for example you set the number to be 5 and when you reach backup number 6 the first back will be deleted for you. | stackexchange-wordpress | {

Passing a variable via wp_head and then calling it on the page
As my question suggests I'm having difficulty creating a variable in the header, via functions.php and wp_head, and then calling that variable further down the page.
For example, in functions.php
add_action( 'wp_footer', 'add_ran_var' );
function add_ran_var () {
$random_variable = "1";
}
And before the
</head>
tag include
<?php wp_head(); ?>
in header.php
The problem arises if i try to call $random_variable later on in the page. It returns nothing.
<?php echo $random_variable; ?>
Could anyone please shed some light as to why this does not work? Has it something to do with the order the different files (header.php, functions.php) are called?
Thanks in advance to anyone who can offer me some advice on the above.
Cheers Noel | Before you use your `$random_variable` for the first time you need to globalize it , something like:
global $random_variable;
then next time or any time you want to access it just call globalize it again and it will be available like this:

Why is `add_meta_box` not working?
I'm trying to add some meta fields to a WPSC product using the following code:
/**

echo 'callback executed!';
}
/**

{

add_action('load-post-new.php', 'abc_load_post', 10, 2);
The `abc_load_post` function gets called fine but nothing actually appears on the product editing page (i.e. `/wp-admin/post.php`)
Can someone explain what I'm doing wrong? | I can see 2 problems with your code. You seem to want that meta box to appear on product pages, but you actually add it to the post type and not the product post type. The other problem is the hook you attach your function to. Try this:
add_action( 'add_meta_boxes_{post_type}', 'abc_load_post' );
Substitute {post_type} with whatever post type you actually want to target, e.g. product, post or page. The fourth argument for add_meta_box() is the post type, btw, which you have set to 'post'. | stackexchange-wordpress | {

Remind a user about their account if they have not used it for 6 months
I have a website working with a user registration/login system all working also.
I wish to automatically send all users an email that have not used their account for 6 months. I have an idea, but just wondered if there would be a better/more convenient solution.
Because this will be done in PHP, I guess this requires a cron job, which isnt a problem as I have done many of them before. Wordpress just doesnt seem to store the last time a user visits my site (to my knowledge). I then thought I could just store in the database (manually) the last time a user visits the site, and run a comparison to the current date in a PHP cron file.
Has anyone got a better suggestion? Or even a plugin to do it for me :p
Thanks! | Take a look at the Transients API. It's meant to store data temporary. Note, that this doesn't replace a cron job, as it needs "Action" on the site. So if the site isn't requested, where you set/alter/delete a Transient, then nothing happens. | stackexchange-wordpress | {

So, current post progression:
Draft --> Pending Review --> Scheduled/Published

No need to go outside the WP template hierarchy. If you want something like `~/user`, then use the `Rewrite API`.

Q&A lite plugin comments

How can I get more out of `$post` in an `add_action` callback?
I have the following action callback set up:
function abc_save_post($post_id, $post)
{
// do stuff
echo '<pre>'.print_r($post,true).'</pre>';
}
add_action('save_post', 'abc_save_post', 10, 2);
The thing is that `$post` is a very trimmed down version of `$_POST` and is missing lots of data that I want to get at. How can I get more data into `$post`? | Simply use the post ID, provided by `$post_id` (and stored at `$post->ID`) to use the various functions WordPress provides to get any extra data related to that post (`get_the_terms`,`get_post_meta` etc).
Performance wise you suffer no loss by using these functions as opposed to trying to force more data into the `$post` object (probably the reverse in fact), since WordPress caches data related to posts (such as taxonomy terms, post meta,...) | stackexchange-wordpress | {

reverse next/prev page order
I think the way wordpress display previous and next posts is basically non sense, with next posts on the left side, and older posts on the right side.
I am using the code
<?php posts_nav_link() ?>
is there a way to reverse such order? | This is because it is, by default, done as 'previous page' on the left, and 'next page' on the right. Posts appear in reverse chronological order, with the latest post first, so 'next page' means going back in time. So in terms of pages it makes sense, in terms of chronology it doesn't.
Anyway... this should work:
<div class="navigation">
<div class="alignleft"><?php next_posts_link('« Older Entries','') ?></div>
<div class="alignright"><?php previous_posts_link('Newer Entries »') ?></div>

How to Loop with the final result formatted differently?
I need to list post_title's in this specific format (note the last title in the list **must not** have a comma)
"post_title","post_title","post_title"
I thought a mini-loop might work. Here's what I'm using
<?php query_posts('cat=0$posts_per_page=-1'); // query to show all posts independant from what is in the center;
if (have_posts()) :
while (have_posts()) : the_post(); ?>
'<?php the_title(); ?>',
<?php endwhile; endif;
wp_reset_query();
?>]">
But I need the final post_title to have no trailing comma? | I'm not sure of the context for this, but `query_posts` probably isn't what you want to use. (See this answer).
( _Untested_ ). I would use get_posts:
$posts = get_posts(array(
'numberposts'=>-1,
'category'=>0
));
And then use `wp_list_pluck` to get the titles:
$post_titles = wp_list_pluck($posts,'post_title');
$post_titles = array_map('esc_html',$post_titles);
Finally, the php `implode` function an list them with commas:
echo '"'.implode('","',$post_titles).'"'; | stackexchange-wordpress | {

wp_upload_dir how to get just the directory name .
I imagine that this would be a breeze for some - but I'm having difficulty getting just the upload's directory name - not the full path - I've gotten this far:
$uploads = wp_upload_dir();
$upload_path = $uploads['baseurl']; // now how to get just the directory name?
anyone have any ideas? thanks for sharing your experience. . . | This is what you get back from the function:
Array
(
[path] => C:\development\xampp\htdocs\example.com/content/uploads/2012/04
[url] =>
[subdir] => /2012/04
[basedir] => C:\~\example.com/content/uploads
[baseurl] =>
[error] =>
)
So you can get the (as @OneTrickPony pointed out), folder/directory name with
echo wp_basename( $uploads['baseurl'] );
If you're running multisite and you defined the constant `UPLOADS`, then you access it from `UPLOADS` or `BLOGUPLOADDIR`.
**EDIT**
For multisites, you would get something like this:
Array
(
[path] => /var/www/example.com/public_html/wp-content/uploads/sites/2/2016/12,
[url] =>
[subdir] => /2016/12,
[basedir] => /var/www/example.com/public_html/wp-content/uploads/sites/2,
[baseurl] =>
[error] => ,

Proper Network Activation problem has been fixed in wp 3.3.1 or not?
@scribu opened a core trac ticket here for Proper Network Activation problem in multisite. It seems like its fixed in wp 3.1.
But scribu was saying it doesn't fixed in wp 3.1.
So he released a plugin for proper network activation.
I'm using wordpress multisite. So can anyone tell me whether this problem fixed in wp3.3.1 or not? | In short: No, it hasn't been fixed - You should use the plugin instead.
In Detail: Activation hooks should work for the main site properly. For subsites (or as Nacin pointed out: for all sites), you should use a proper upgrade routine. _Not that I double that 1)._

post/page content
I am trying to insert a post/page into one of my themes files and it won't display shortcodes or PHP.
I have created a page called home in the wordpress admin-paned and inserted into my code the following:
<div id="home_page"> <!-- echos the content from the page "home" id:43 -->
<?php $home_id = 43;
$home_page = get_page( $home_id );
?>
<?php echo $home_page->post_content; ?>
</div> <!-- end #home_page -->
and non of the shortcodes that I have in the page work. I installed a `php in post or page` and tried using php and it doesn't work.
when I insert
echo do_shortcode('[youtube_sc url=
directly into the code it works.
does anyone know y this happens?
thank you. | You need to apply the filter `the_content` e.g.:
<?php echo apply_filters('the_content',$home_page->post_content); ?>
Also, you don't need custom shortcodes for youtube, just put the URL in the content (but not a hyperlink), and it'll be swapped out for a youtube player at runtime. No plugins or extra code needed thanks to oembed. | stackexchange-wordpress | {

Combining the_excerpt with the_content
I have some html:
<div class="container">
<p class="accent">The first paragraph...</p>
<p>The rest of the article...</p>
</div>
I'd like to put "the_excerpt" in the first paragraph (with a special colour / font size) but then have the following text be "normal".
Is there a way to **subtract** the_excerpt from the_content so the section "The rest of the article" does not repeat the excerpt? | The key is to use **user-defined excerpts** , rather than auto-generated excerpts. For example:
<div <?php post_class(); ?>>
<?php
// If post has defined excerpt, output it here
if ( has_excerpt() ) {
?>
<div class="first-paragraph-excerpt">
<?php the_excerpt(); ?>
</div>
<?php
}
// Now output the content
the_content();
?>
</div> <!-- .post -->
You'll need to adapt to your needs, but this will output a div with the Excerpt, if it exists, and then output the content. | stackexchange-wordpress | {

I put my blog on a subpage, how do I get page title?
I've got my blog setup on a subpage (not the front page) and I'm using the template file `home.php`, how can I get the contents from the page editor onto this subpage?
If I change the title of the page it changes in the nav menu, but how can I get this to display on the page? (i.e. as the `<h1>` header) | Untested, but try:
<?php
echo get_the_title( get_option( 'page_for_posts' ) );
?>
But it's _somewhat_ hackish. Really, the `page_on_front` and `page_for_posts` are intended to be nothing more than _placeholders_ for the site front page and blog posts index page. | stackexchange-wordpress | {

Remove Tag from theme support

writing a plugin, how to disable the comment form altogether?

How to get post category title within the loop?

Getting a role based on a localized role name
I use the following code to get the Administrator role
$admin = get_role('administrator');
This works fine, but on a different WordPress language setup, this code breaks. For example, in French it should be
$admin = get_role('adminstrateur');
Any cross-language solution? | Just guessing, but maybe:
$admin = get_role( __( 'administrator' ) );
If you're trying to make sure that WP translates the string for a specific locale, `__()` will return the translated string. So if `get_role('administrator')` works and on a French setup `get_role('administrateur')` would work, then the above code snippet should do what you need. | stackexchange-wordpress | {

RSS feeds and wordpress?
I'm working on my first wordpresss website and I've really never worked with RSS feeds. However my friend that I'm doing a website for wants it in there. so I guess I'm in a crash course learning session with google to learn all I can about RSS feeds.
I was hoping to find a plugin that just allowed the visitor to subscribe to the websites blog but they are all pretty ugly, or not what I want.

I'm hoping to have an email field that I can style like the way I have designed it here.
Or even something like the way this website has it done
Are there any good plugins and articles to read up for a beginner wordpress theme developer to learn this RSS feed information? | As you develop WP theme, I would mention that you need to enable automatic-feed-links by adding following function call to your functions.php file:
add_theme_support( 'automatic-feed-links' );
After it RSS links fill be added automatically to head of your site. The best practice is to add this call in function for `after_setup_theme` hook handling:

add_theme_support( 'automatic-feed-links' );

What is the cleanest way to extract custom variables from a post

$custom_values = get_post_custom_values('tenderfields');
$custom_values = unserialize($custom_values[0]);
$custom_values = $custom_values[0];
Then accessing them with `$custom_values['my-custom-value']`
This works fine but feels a little clunky, it feels like something there is probably already an internal call for that I am just missing?
I have looked through the docs and couldn't find anything. | If you always need **all** of post meta at once this is the way to do it.

Alphabetical search
Is is possible to create an alphabetical search like so:
A | B | C | D | etc
Each letter is a link so when clicked it would show all the posts starting with "A" or "B" etc etc.

global $wpdb, $post;
$letter = 'a'; // or $_GET['letter']...
$query = "SELECT * FROM {$wpdb->posts} WHERE post_name LIKE %s";
$query = $wpdb->prepare($query, $letter.'%');
$results = $wpdb->get_results($query);
// note that variable name must be $post,
// because you need to override stupid wp globals...
foreach($results as $post){
setup_postdata($post);
// the usual loop functions go here

wp_verify_nonce vs check_admin_referer
What is the difference, which one should I use?
I know that wp_verify_nonce checks the time limit, and check_admin_referer I think calls wp_verify_nonce as well as checking for an admin url segment, but I'm a bit confused on which one I should use and when.
Thanks for the clarity. | I _thought_ that `check_admin_referer` checked the nonce (it does call `wp_verify_nonce`, **and** the referring url. After digging into the core code I realised that it did not do this. Thinking it was a bug I reported it, and Ryan Boren replied with the following:
> Actually, if the nonce is valid the referrer should not be checked. The unreliability of referrers is one of the reasons that nonces are used. Nonces replace referrer checking entirely. The only time we check the referrer is when handling the -1 backward compatibility condition. -1 means that someone is not using nonces so we fall back to referrer checking. This usage is now very rare. check_admin_referer() is badly named now that it almost never does referrer checking. It would be better named something like check_nonce(), but we keep it as is for back compat and old times sake.
So there is in fact there is no difference. | stackexchange-wordpress | {
