Author bio Social Links
I'm using simple code to show user social link in author bio. **in functions.php**

function add_remove_contactmethods( $contactmethods ) {
// Add Twitter
$contactmethods['twitter'] = 'Twitter';
//Add Facebook
$contactmethods['facebook'] = 'Facebook';
// Remove Contact Methods
unset($contactmethods['aim']);
unset($contactmethods['yim']);
unset($contactmethods['jabber']);
return $contactmethods;
}
add_filter('user_contactmethods','add_remove_contactmethods',10,1);
?>
**in single.php**
<a href="<?php the_author_meta('twitter'); ?>" title="Twitter" target="_blank" id="twitter"><img src="/images/twitter.png" alt="Twitter" /></a>
so how can i hide social link in author bio when the field is empty in user profile.
please help me... | You need to check, if the field is empty or not before printing link using the get_the_author_meta function.

Best way to abort plugin in case of insufficient PHP version?
You write a plugin which requires PHP 5.1. Someone tries to install it on a server with PHP 4. How do you deal with that in a safe and user-friendly manner? | /**
* Plugin Name: Foo
*/
// Check for required PHP version
if ( version_compare( PHP_VERSION, '5.1', '<' ) )
{
exit( sprintf( 'Foo requires PHP 5.1 or higher. You’re still on %s.', PHP_VERSION ) );
}
// The rest of your plugin code follows
I'm not sure since which WP version this happened, but in 3.5 the plugin actually fails to activate and the error message is shown to the user in the admin, which is neat.
The error message is not translated, though. In order to do that you’d have to load your translation files right before the `exit` call. | stackexchange-wordpress | {

A single category with a specific permalink structure differing from the standard set for the rest of the site
I'm interested to know if there's a method to specify a specific link structure for only a single category.
Currently I have my install set to **/2012/12/post-title**. However there is a single category I would like to set to **/category-name/post-id/**. Part of this is that I don't plan to title any of these posts, but I also would like to make it simple to block this section from being crawled using the _robots.txt_ file.
_Possible caveat, I'm using Nginx rather than Apache, so rewrite rules if needed will differ._
Thanks | You can use URL rewrites to edit the displayed URL, but without changing your actual wordpress setup all your internal links will still point to the structure assigned in your permalinks settings.
The most straightforward way to do this would be by using a custom post type. With CPTs you can set up a whole different structure for your posts and get as customized or as standard as you want with how wordpress handles it, both internally and externally. You can even make custom taxonomies (post categories is an example of a taxonomy) and associate it only with that CPT.
You can do this manually by editing your functions.php file (good tutorial here) or use a plugin like this one to do the heavy lifting for you.
Here's the codex for registering CPTs
I've recently gotten pretty deep into custom post types, use role creation and management and such. It's really powerful and will save you a lot of hassle with URL rewrites. | stackexchange-wordpress | {

Two WordPress sites sharing the same content
My question is this:
Is it possible to have two separate installations of WP with two separate domains sharing the same content?
**Scenario:** User on < publishes a post. < uses the exact same database and can show that post as if it was its own.
I've been looking around for quite some time for this solution and cannot find a valid procedure to achieve this.
**My ideas are:**
1. Is there a way to share the database without having the issue of the siteurl and theme stored in the database be an issue.
2. Maybe use just an RSS feed and somehow parse the XML and display them in a template. This is not the best idea because it would have zero functionality that WordPress provides.
3. Find a way to somehow sync the databases but exclude the wp_options table ? | If your main requirement is to synchronise blog posts from a master site to a slave, then maybe look at the FeedWordPress plugin. It means that you would only add/edit posts on one website and they would be replicated to the other site. That will allow you to cleanly run different plugins on the two sites. | stackexchange-wordpress | {

add_filter on "the_excerpt" only works when post does not have excerpt
class my_menu extends WP_Widget
{
function widget($args, $instance)
{
// Excerpt length filter
$new_excerpt_length = create_function('$length', "return " . $excerpt_length . ";");
if ( $instance["excerpt_length"] > 0 ) {
add_filter('excerpt_length', $new_excerpt_length, 999);
}
//...
}
}
This filter works great if the post does not have an excerpt. How do I apply the same filter to a post that has an excerpt?
In other words, when the post has an actual excerpt, its not filtering it at all, the whole excerpt is displayed. However, when the post does not have an excerpt, the get_the_excerpt() call gets filtered so that it only returns the number of words specified by "excerpt_length" | I posted an article about this a while ago:
function wp_trim_all_excerpt($text) {
// Creates an excerpt if needed; and shortens the manual excerpt as well
global $post;
$raw_excerpt = $text;
if ( '' == $text ) {
$text = get_the_content('');
$text = strip_shortcodes( $text );
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
}
$text = strip_tags($text);
$excerpt_length = apply_filters('excerpt_length', 55);
$excerpt_more = apply_filters('excerpt_more', ' ' . '[...]');
$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);

Theme Activation, Create Database Tables
I have been tasked with creating a theme that will be a base to list the site owners ebay store products.

Count posts published in one particular day: the lighter way
I would like to get just the number of posts published in one particular day. I'm using this code, but this retrieve lot of code:
$day = date('Ymd');

$mypost = get_posts($query01);
$counter = count($mypost);
wp_reset_postdata();
Is there a lighter way to obtain the same? | `$wp_query->found_posts` can be used to get the number of posts. But here are arguments you can use to optimize the query and avoid useless SQL retrievals:
cache_results' => false, // Turns off post caching
'no_found_rows' => true, // To optimize when pagination is not required
'fields' => 'ids' // To only retrieve IDs information, nothing else (avoid collecting all useless post data)

Show category children, one level
I am coding a pretty complex wordpress site (at least, taxonomically speaking), and i need to display a list of categories, children of a parent category, but I am struggling with getting the code to do this.
I tried doing something like:
<?php
$cat = get_query_var('cat');
$categories= get_categories('hide_empty=0&parent=1&child_of='.$cat);
foreach ($categories as $category) {
$mycat .= $category->cat_name;
echo $mycat;
}
?>
But i don't seem to get the correct output.
Do you have any idea? Thx! | Why are you using the parameter parent=1? If you remove this parameter it should work.
If you want children and grandchildren, you should use:
$categories = get_categories('hide_empty=0&child_of='.$cat);
If you want only direct children, you should use:
$categories= get_categories('hide_empty=0&parent='.$cat);
Also note that you are echoing $mycat inside the loop, and you are joining the multiple categories in this var, so the categories should appear repeated... | stackexchange-wordpress | {

Searching for this symbols in Google seems futile... | Those are javascript templates that get compiled into HTML by a javascript library. I think WP uses underscore.js.
Let's say you write a jQuery plugin, and you have to append HTML code to the document. Using such templates you can avoid stuffing that HTML code inside huge concatenated strings within your javascript code, and put it where the other HTML markup is. So you load that template from your plugin, compile it (variables get replaced) and append the resulting HTML to your document. Essentially you separate the business logic from the presentation logic. This also makes your plugin more decoupled. | stackexchange-wordpress | {

$wpdb->prepare() warning in WordPress 3.5
I am receiving this warning when I try to run a database query:
> **Warning:** Missing argument 2 for wpdb::prepare()
The offending query is:
$result = $wpdb->get_var(
$wpdb->prepare(
"SELECT DISTINCT meta_value FROM $metatable
WHERE meta_key LIKE '%matchme%'
AND meta_value IS NOT NULL
AND meta_value <> ''"

);
In this case, the `$wpdb->prepare()` function is **not doing anything**. There are no variables holding unknown values, therefore there is no need to sanitize them.

Wordpress plugin updates / set file as immutable to prevent certain files from changing?
I'm wondering--what is the best way to prevent a file (say, a custom CSS file associated with a plugin) from being overwritten during the update process?
Would setting the file's status as immutable do the trick, or would this just cause an error during update? What is the best way to go about doing this? | Basically you should not include the file in the plugin in the first place. If the reason you don't want it to be overwritten is because you modify it based on some local setting, then you should leave the immutable part of the file in it and create another file which will contain the mutable parts.
Then you can use your CSS like that (assuming you suplly constant.css with the plugin and generate costum.css locally.

function my_plugin_addcss() {
// register and enqueue the immutable part

Linking to page with all posts
I'm new to the Wordpress world. I've read the template hierarchy document and read online, but, I wanted to get feedback from here on what the best way to do this would be.

Prevent network activation of plugin
I have a plugin that currently doesn't support network activation. The best fix for this of course is to fix it :) which I plan to do. However I wonder if there is a temporary solution I can use to prevent network activation in the meantime, perhaps a workflow similar to:

2. Display message that it's currently not supported, and I stink, I'm sorry
3. Interrupt the activation or deactivate
Or, other suggestions accepted. Thanks.
For clarification: Multisite activation is fine, just not network-wide activation. | The answers here are overthought and too complex. Why deactivating the plugin instead of preventing activation? Something as simple as calling die('your error message here) upon activation will do the job.

}
register_activation_hook('your-plugin/index.php','activate');

should i use GLOB_ONLYDIR to hook add-ons for wordpress plugin
I am adding the ability to add add-on to my plugin. Right now i am using:
foreach(glob(GMW_PATH .'/plugins/*', GLOB_ONLYDIR) as $dir) {
include_once $dir . '/connect.php';
}

This is the first time i am using GLOB_ONLYDIR and i am not sure about its performance. Is it a good idea to use the above or should i create each add-on as a stand alone plugin, which they actually are, but add the a ability to just activate them from the plugins page?
Thank you. | Depends on your plugin. I prefer to use plugins with the minimal functionality that meets my needs. Less configuration options, less documentation to read, and hopefully less bugs. You also need to think on the upgrade process. If you make a change in a big plugin I should look into upgrading it even if the change is in a functionality I don't use, and upgrades are always risky or take time to test.
Therefor, if you can break up your functionality into several plugins, that is the way to go IMO. But if it is not possible for what you do, then before you think about distributing addons for your plugin, think how are they going to be installed and upgraded. Unless you have a good plan for managing the addons I suggest you distribute them with the main plugin and then you can directly include them without the need for `GLOB_ONLYDIR`. | stackexchange-wordpress | {

My host does not allow me to use "Options" or "DirectoryIndex" within a .htaccess file. I have tried putting a .htaccess file in the /uploads/ folder with "IndexIgnore *" in it. However none of my images from the /uploads/ folder will show up on my site with that option. I also tried password protecting the directory with a .htpasswd file but this gives any visitor of my site a popup asking them to enter the credentials.
So my question is how do I prevent people from browsing the directories while enabling me to embed files from those directories in my wordpress posts/pages.
For example, can I place .htaccess file in the /uploads/ directory and add RewriteRules so WordPress can still show the files on my website? | To disable directory browsing all you have to do is drop in a blank `index.html` file into the `wp-content\uploads` directory, each subsequent sub-directory also would need a blank index file, there are plugins that can automatically do this for you.
ps. Get a better host, there is no reason they should disallow you having your own .htaccess files. | stackexchange-wordpress | {

How do I use WP_query with multiple post IDs?
I want to query multiple posts with an array of IDs (note: I am querying a custom post type).
Here's what I have, which isn't working:
$myarray = array(144, 246);
$args = array(
'post_type' => 'ai1ec_event',
'p' => $myarray
);
// The Query
$the_query = new WP_Query( $args );
Any tips on how to do this? | Please reference the Codex entry for post/page parameters for `WP_Query()`.
The `'p'` parameter takes a single post ID, as an integer.
To pass an _array_ of posts, you need to use `'post__in'`:
$myarray = array(144, 246);
$args = array(
'post_type' => 'ai1ec_event',
'post__in' => $myarray
);
// The Query

How do I programatically remove Menus?
I know that each menu item is simply post present in `nav_menu_item` post type. It has has ID and can be removed with `wp_delete_post()` but posts deleted this way don't remove menus present under [Appearance > Menus]. Only menu items are removed.
For instance I have "My Menu" under [Appearance > Menus] that has the following items: page-1, page-2, category-3. I can remove menu items with `wp_delete_post()` but "My Menu" (group for those items) remains intact.
How can I programatically remove all defined Menus (and menu items)? | Please check wp_delete_nav_menu() function. If you want to get all nav menus you can check wp_terms table or

Shortcode content does not show in feed discription/excerpt

How to change post template
I have a post featuring a product that I've created using advanced custom fields. I would like to have a link on the post that opens in a new window and displays the same product, just with a different look and info. (Note: I'm specifically looking to use a second template and not a different CSS because different info will be displayed on each template.) I've tried using the code below, but my custom template just returns a blank page. Can anyone suggest a fix?
Here's the link I'm using on the original template.
<a href="<?php the_permalink(); ?>?custom-template=1">Link</a>
Here's the code that I'm putting at the top of the custom template.
if ($_GET['custom-template'] == 1) { include custom-template.php; return; }
Thanks, John | The way I see it you have two options here:
1. Pass the id to a custom template and then create a custom `wp_query` loop and use `$_GET['id']` as the id of the loop.
For Example:
<?php
/*
Template Name: Pop Up View
*/
//get id from your url
$id=$_GET['id'];
//start custom loop
$query = new WP_Query( 'p=$id' );
//loop stuff and page template here
?>
then you would call `<a href="custom-item-template?id=<?php the_ID();?>">Link</a>`
Or going more with your current code you could do something like
if ($_GET['custom-template'] == 1) {
get_template_part( 'custom-template');
die(); //or exit();
}
This fixed a few problems I see with your current code. One being that return can't be used outside of functions. Also uses get_template_part instead of include with is a more WordPress way to do it.
Both ways should work, hopefully that gets you on the right track. | stackexchange-wordpress | {

Advanced Custom Fields - category image
I'm trying to get an image for I previously assigned to a category using ACF.
here's what I'm doing:

261, , catsmall, , , Array
Any idea what I'm doing wrong? Many thx!
Alex | Whenever in doubt, consult the documentation and nice plugins like ACF are very well documented.
It depends on how you set the image field, but from this page _Field Types -> Image_, looks like you set you field to return an object.
Instead of using `the_field`, which _prints_ the value, you need **`get_field`**:
$category_image = get_field('cat_small', $linkedcat);
And then:
$image = $category_image['url'];
Or, if available:
$thumb = $category_image['sizes']['thumbnail'];
Also, instead of `echo`, use `var_dump` to debug arrays. | stackexchange-wordpress | {

> Remove navigation from header in custom page template
Is there some way to remove `wp_nav_menu` in a page template? I can't find anything related to page templates other than redirect default theme files etc.
I know that just placing the `header.php` content in the page template will do the trick but this seems a awkward hack.
Thanks for any clue. | Without knowing your theme, you have at least a few options. You could 1. hide it with CSS.
.your-page-template-php #your-menu {
display: none;
}
Or 2. you could create a custom header file. For example, duplicated header.php to header-nomenu.php. And in your new file delete the menu. And then in your page template instead of calling
get_header();
you'd call
get_header('nomenu');

**EDIT**
Upon further review there _is_ a filter inside the `wp_nav_menu` function. Conditional logic will probably work as long as you haven't messed around with the query object and forgot to reset it.

Remove navigation from header in custom page template
I'm building a landing page and want to remove the navigation menu from the page. The navigation menu is in header.php which is of course in the page template. Is there a WordPress function I can use to remove the navigation menu from this specific page? I know I could do it with jQuery and do display:none for the nav menu but i'd like to do it server side before the page loads.
Thanks | ## Use a conditional tag:
Codex References:
Function Reference (is_page)
Function Reference (Conditional Tags)
You can specify the landing page by Page ID, Page Title or Page Slug.
Here is an example:
<?php if ( !is_page( 'landing-page' ) ) {
wp_nav_menu( array(
'show_home' => 'Home',
'container' => 'false',
'theme_location' => 'main')
);
}
endif;
?>
It excludes the page (in this case the page with the slug "landing-page") by placing the **`!`** in front of `is_page`

Filtering a Database Query
In a WP_List_Table example I'm using, I am seeing how to make a general query to the `wp_options` table in the Wordpress database.
For example, `$query = "SELECT * FROM $wpdb->options";`
I also see that we typically create a `foreach` loop to display all the records in this table on separate rows. Sounds easy enough.
But I would like to filter this query to reference an "options array" instead. This is a single value in my table. For example, I want to query a single option called `testimonial_settings` and then retrieve all the array values from this single field. I can't wrap my head around how I would do this using a `foreach` loop.
Maybe a simple example showing the proper syntax would help clear things up....? | The table `wp_options` can normally be queried using get_option()
So you can use something like
$testimonial_settings = get_option('testimonial_settings');
to retrieve the values of `testimonial_settings`. If the stored value is serialized, it will be retrieved as an array. | stackexchange-wordpress | {

Speed optimization of $wpdb->get_results
I'm using this code to generate all my custom field values from all posts for custom field named "autor".
<?php $autor = $wpdb->get_results("SELECT meta_value AS autor FROM wp_posts, wp_postmeta WHERE post_status = 'publish' AND meta_key = 'autor' GROUP BY meta_value ORDER BY meta_value") ?>
<ol>
<?php foreach( $autor as $autori ) : ?>
<div class="autor">
<li><a href=" echo $autori->autor ?>"><?php echo $autori->autor ?></a></li>
</div>
<?php endforeach ?>
</ol>
It works okey, but the problem is that it takes a couple of seconds more (like, the page is loading for 5-10 seconds) for server to load that particular page. Is there any way to optimize this request? | Your query is incorrect in the first place because you're not doing the join correctly. What you're actually selecting with that query is just all the postmeta's autor fields, without regards to whether the post is published or not.
Here's the corrected query.
SELECT meta_value AS autor FROM wp_posts
JOIN wp_postmeta ON (wp_postmeta.post_id = wp_posts.ID)
WHERE post_status = 'publish'
AND meta_key = 'autor'
GROUP BY meta_value
ORDER BY meta_value
This will probably be faster because the proper join will eliminate a lot of the posts. It's not fully optimal, but it will give some improvement. | stackexchange-wordpress | {

Do i need the git directory?

So leave the .git folder there, don't touch it, if you must, back it up before deleting it.
If it's been put there as part of the auto installation then removing it could cause issues if your host tries to update it, or if it uses that folder to check if there's a WordPress install

How to determine wordpress base path when wordpress core is not loaded

Adding schema itemprop image to the_post_thumbnail with filters
I have tried to apply filters to the_post_thumbnail() function using
apply_filters( 'post_thumbnail_html', $html, $post_id, $post_thumbnail_id, $size, $attr );
Here's the code I have come up with but doesn't seem to work completely
function red_adjust_image_schema($html, $id, $caption, $title, $align, $url, $size, $alt)
{
$html = '<div class="image-container" itemprop="image">'. $html . '</div>';
return $html;
}
add_filter('post_thumbnail_html', 'red_adjust_image_schema', 20, 8);
How can I add itemprop="image" to the actual image element so it registers properly? Right now it seem like I can only do a container and wrap around $html?

WPMU - How to echo only one URL

What is the Difference in bones_comments() and comments.php
I started to use Bones HTML5 Wordpress Starter Theme, but a little confuse with some built-in function in bones,
There is `function bones_comments()` in functions.php but I cannot find anywhere on the files where this function is used or called.
And I take a look at the code in the function it just looks like some code to output wordpress comments, and yet there is comments.php for comment_template() in wordpress.
So really confuse why bones add the bones_comments() function and not use it. and what is the difference between bones_comments() and comments.php | It is a function created to be used as a hook.
Inside the comments.php file is
<?php wp_list_comments('type=comment&callback=bones_comments'); ?>

Why is inline CSS added to images automatically?
I have placed images on Wordpress page templates without any inline style attribute but it seem Wordpress automatically add style tag with `width` and `height` set to zero.
<img src="wp-content/themes/ecoblog/images/hiw-image-1.png" style="width: 0px; height: 0px;">
Sometimes height is set to its original dimentsions and sometimes after complete refresh its values are zero.
What is causing this? | Before you ask a question: maybe check on a other install of WP, is this the default? It is not? The problem is very often from plugins or themes. Disable plugins and switch to the default theme, current Twenty Twelve and check your problem.

page 1 is not paged
I have rules that only work on paginated pages (is_paged). However, they don't work on page number one (/page/1).

How to assign custom template to specific products in Woocommerce?
I figured out how to assign a template to a product category (from this thread Different template of products for specific category. WooCommerce), but I'm wondering if I can assign a custom template to specific products.
EDIT: For more clarity, I want to have a certain style applied to the category page, but when I click on one of those products, I want to keep that same style. | If the changes you need are strictly CSS, you can add the category names as classes to the `body_class` via the `body_class` filter.

function wpa76627_class_names( $classes ) {
if( is_singular( 'product' ) ):
global $post;
foreach( get_the_terms( $post->ID, 'product_cat' ) as $cat )
// maybe you want to make this more unique, like:
// $classes[] = 'product-category-' . $cat->slug;
$classes[] = $cat->slug;
endif;
return $classes;
}
This code checks if we are viewing a single product page, then loops over all product_cats, adding the slugs as classes to the body tag. This could also be adapted for any post type or taxonomy. | stackexchange-wordpress | {

Which action hook can I use when a featured image has been selected
I have made a plugin for wordpress which copies the image to another directory when a post has been edit. But if you only upload another featured image and don't save the post.

The action which I now use for the post edit is wp_insert_post().

* `updated_postmeta`, after the data is written into the database. Previously `updated_post_meta`
### SECOND EDIT: No need to panic
`updated_{$meta_type}_meta` and `update_{$meta_type}_meta` still work.

Only make custom image size if uploaded via Thickbox and attached to certain page

What is the advantage of the wp_options design pattern?
As we all know, a design pattern that is used frequently in WordPress' DB code is the idea of persisting data for a particular object (blog/post/comment), indexed with a particular name or key.
We see this pattern used in the following standard tables:
* wp_options
* wp_commentmeta
* wp_postmeta
As far as I can tell, the motivation for this design decision was to enable plugin/theme authors to persist data easily (e.g. by using custom fields) without having to modify the database schema. It would seem to me that there are few other advantages to this approach, since it is significantly slower and makes it harder to implement complex queries.
What are the other advantages to this approach, if any?
* * *
UPDATE: Reading info on the drawbacks of this approach:
* <
* < | The ability to store abstract key-value pairs without modifying the database structure is _the_ reason. Without that, WordPress loses **_much_** of its flexibility. I can't speak for others, but the single largest reason why I develop atop WordPress is its flexible nature.
To quote one of your links above,
> Usually the reasoning behind doing what you are doing is because the domains need to be "user definable". If that is the case then even I am not going to push you towards creating tables on the fly...
While it's true that it forces queries to be more complex, and a little slower, the benefits far outweigh the costs. But, hey, it's all about what you're doing. Don't use a hammer to bang in a screw.

That's because that's what your callback is telling the filter to do. It returns true for _all posts_ in your specified contexts (archive index, category index, blog posts index), _not_ just for the _first post_ in those indices.
> ...and removing the_content() altogether on all of the single pages.
That's because, if your conditional returns false, you don't return anything. You need to `return $content;` outside of your conditional. | stackexchange-wordpress | {

Update feed more frequently
When i publish new posts, i notice the new posts do not appear in the feed ` instantaneously, there is always lag time, one or several hours.
When i change something in `wp-includes/feed-rss2.php` file (just `echo 'test'`), it also takes one or 2 hour to see the `test` word in ` it means wordpress only use that file periodically.
Anyone know how to solve this problem? I want whenever the ` page is open in browser, it must use `wp-includes/feed-rss2.php` file.
Thanks! | Just like the pages WordPress makes normally, feeds are generated on-demand, they're not "rebuilt" or "updated" or any sort of thing like that. So posts will appear in the feed at the exact instant that they are published.
If you're seeing a lag time, then you may be using a caching plugin, such as WP-Super-Cache, or some form of feed redistribution service, such as FeedBurner, which is holding a copy of the feed for some period of time and only refreshing from the actual feed periodically.
In this case, you need to either configure the caching plugin to not cache the feed, or stop using the feedburner-like service. | stackexchange-wordpress | {

How to track hits of a single media file?

How can I do this? | You could use Google Analytics for WordPress. Here's an excerpt from their FAQ on how you could set it to track certain file types:

Does dbDelta delete columns as well?

Post incorrectly displaying as page
I have a small WordPress install that I'm setting up, and have run into an issue that I've encountered before, but do not understand the cause.
Issue: With permalinks set to `/%postname%/`, on a site with the following:
1. Home page
2. About page (slug: "about")
3. Two links to categories (there are two categories, with slugs of "digital" and "broadcast")
4. About 35 posts
Most everything works as expected, however there is one post with a slug of "swampism" which displays (incorrectly) in the page.php template file, rather than the single.php template file (where all other posts properly display).
How does this happen? Why does it happen? And how can I fix it and/or avoid it in the future.
**Note:** Changing the permalink structure to default, or date driven is not an option. Besides, that is (in my mind) a work-around, not a solution/explanation of the problem. | I was going to make this a comment but it was getting long and I think I see an answer emerging. I'll gamble.
If this is the problem URL: < you are seeing an attachment page `<link rel='canonical' href=' />` WordPress shows these when individual images are requested. I am starting with that assumption.
The image on that attachement page is, interestingly, named `Swampism.jpg` which, if the pattern I see in my DB holds, means it has the slug of 'swampism'. I am betting that that is where you conflict is. WordPress is finding the image slug and loading the attachment page for it instead of finding your "page-name" slug. | stackexchange-wordpress | {

Output in XHTML or HTML 5 for plugins?
I'm currently writing a plugin that displays some images - possibly with captions. So, I was wondering whether to use XHTML (`<div>`s and `<span>`s) or HTML 5 (`<figure>` and `<figurecaption>`) for output.
I image that the answer to this question depends somewhat on the theme being used. Is there a way to figure out which output format the user's theme is using? Or what's the best approach here? What's Wordpress doing to solve this issue? | WordPress will not help you here. In back-end use conservative XHTML 5: `<br />`, but not `<figure>` (see WP coding standards).

wp_redirect not working after submitting form
I'm using this redirect after inserting a post. It's not working, it only refreshes the page the form is on. I know the $pid is getting the post ID so what is the problem? This is the very end of my php code for handling the form submission.
$pid = wp_insert_post($new_post);
update_post_meta($pid,'domain',$domain);
update_post_meta($pid,'keywords',$keywords);
wp_redirect( get_permalink($pid) );
exit();
Here is a pastebin of the complete code
Using Better HTTP Redirects it's output is, and it links the word `here` to the correct newly published post.
302 Found
The document has moved here. | You can only use `wp_redirect` _before_ content is sent to the browser. If you were to enable php debugging you'd see a "headers already sent" error due to `get_header()` on the first line.
Rather than process the form in the template, you can hook an earlier action, like `wp_loaded`, and save some queries to the db if you're just going to redirect away.
**EDIT** , example-
add_action( 'wp_loaded', 'wpa76991_process_form' );
function wpa76991_process_form(){
if( isset( $_POST['my_form_widget'] ) ):
// process form, and then
wp_redirect( get_permalink( $pid ) );
exit();
endif;
}
Using an action, you can keep the code out of and separated from your templates. Combine this with a shortcode to output the form and wrap it all in a class to save state between processing/output, and you could do it all without touching the front end templates. | stackexchange-wordpress | {

Return all Tags from search results
I am wondering if it is possible to return a list of all the "tags" that are associated with ALL returned posts. In theory, I would then use this list of terms to build appropriate "filter by" links for refining the search.
For instance: A user searches for "Foo" and there are 100 results. Would it be possible to get a collection of all the posts' tags? So, post "Foo 1" might be tagged "little bar" and post "Foo 2" might be tagged, "big bar" and "foo foo", etc and etc.
I would like to do this _before_ the `while_posts()` is doing its thing. Failing that, I think I could use the `while_posts()` loop to collect all the tags for each post. This is the most obvious solution to me, except that then the list isn't where I want it in the markup. AND, I'm not sure how to include tags on page 2 (and onward) of the results. | The global `$wp_query` object is available before you call `have_posts()`. All you have to do is running through this object’s `posts` member with `get_the_terms()`.
Sample function:
function get_query_terms( $taxonomy = 'post_tag' )
{
$list = array ();
foreach ( $GLOBALS['wp_query']->posts as $id )
{
if ( $terms = get_the_terms( $id, $taxonomy ) )
{
foreach ( $terms as $term )
$list[ $term->term_taxonomy_id ] = $term;
}
}

Is it possible to insert images directly from the server?
I've uploaded images directly to my WordPress server through FTP. I want to add these images to a post, so right now I'm using the Add from Server plugin that allows me to browse images on the server and add them to the media library. The only thing I don't like about this is that adding an image to the media library generates two smaller versions of the image that are used for thumbnails. Is it not possible to completely bypass the media library and add images directly from the server? | I think that the best option here would be to disable the generation of additional image sizes on adding an image to the media library. Doing so is fairly straight-forward:
Visit the _Settings > Media_ page of your WordPress dashboard. Under the _Image Sizes_ section, change all of the values to 0.
!Media Settimgs
Save the changes. This will stop WordPress generating thumbnails, medium, and large sizes of every image you upload.

function prefix_update_post() {
if ( current_user_can( 'edit_post' ) ) {
// your goodies here

'format' => '?paged=%#%',
'current' => max( 1, get_query_var('paged') ),
'total' => $wp_query->max_num_pages
)

If you imagine the "middle" numbers overlapping the "first" numbers you'd get 3 or 4 or five numbers bunched up.
