Custom loop by url
So currently I have this working for 'search' ie: if I do www.domain.com/search/query, it returns everything it finds on the word 'query'. I would like to utilize that loop/template I created within that search.php but change it to posts. Then query a specific post category if possible ie: www.domain.com/posts/category1
I'm think it all stems off changing
<?php get_template_part('loop', 'search'); ?>
Fairly new to wordpress so any help or suggestions is greatly appreciated! | You can customise the loop query to get results based on a search term - with $s being the search term;

Adding Pinterest Script Before Closing Body Tag
According to the Pinterest website in order to add the Pinterest button to any page I have to add the following just below the closing body tag:
<script type="text/javascript" src="//assets.pinterest.com/js/pinit.js"></script>
What's the best way to do this?
Should I follow the link, grab the script and use wp_enqueue_script? Or can I somehow include the script element another way?
Thanks. | Yes, you have to use wp_enqueue_script function. Pass `$in_footer` argument as `true` and your script will be added before closing body:

What is the advantage of separating wp_users and wp_usermeta table?
I want to know why Wordpress designed their database with two tables separating users and meta from each other. Wouldn't it be better if first_name, last_name, nickname, description, and capabilities are in the wp_users table?
SO what's the advantage for doing this separation? | The meta table is build to allow custom user meta. If anything would be in just one table a plugin developer had to add a new column to the table for each meta data or the data had to be stored as serialized arrays/objects which would made them unsearchable.

How to Custom Edit Post Title & Permalink Slug?
I'm trying to build some functionality where if you're logged into an admin account you'll see a small 'edit' link next to each post title. clicking will use jquery to create 2 form inputs - 1 with the current post title and the other containing the current slug.
I'd ideally like to then allow admins to edit any post/slug from the post page itself using Ajax. To accomplish this I need to find how to update MySQL when the user hits "save". What would be the best way to go about doing this?

What is theme-compat?
I have noticed that `wp-includes/theme-compat` directory.
So, what is it?
Is it a theme? | The `theme-compat` directory is comprised of a set of **deprecated** (since WordPress 3.0) files that WordPress _used_ to use as fallback template-part files, in case the active Theme failed to include them.
In other words, if a Theme used the `get_header()` template tag, but failed to include a `header.php` template-part file, WordPress would fall back to `/wp-includes/theme-compat/header.php`.
The template-part files in `theme_compat` are **deprecated** , unmaintained, incredibly old (by core/current-Theme standards), and should not be relied upon by any current Theme. | stackexchange-wordpress | {

Filter query_posts by tag slug on "Tag Archive" page (when tag is 2 or more words)
I'm using the following to bring up a tag archive page:
<?php query_posts( "tag=". '' . single_tag_title( '', false ) . '' ); ?>

Is it possible to query_posts by tag slug, rather than single_tag_title?

Customize WordPress>Error Page

I'm not talking about 404, but when WordPress displays an error.
I'd like to style this page to match my theme. | You're probably talking about theming `wp_die()`, which is the function that produces those grey error pages with a white box of text in them.
**For a plugin solution** , you could try this plugin, which says it does what you want. Not sure about version support though--it says it only works up to 3.1.4.
**For a programatic solution** , you'll want to hook into the filter "wp_die_handler". So you can do:
add_filter('wp_die_handler', 'my_die_handler');
As far as code for the `my_die_handler` function, you could start by looking at the default die handler -- the function is called `_default_wp_die_handler`, and it starts on line 2796 of the core file `/wp-includes/functions.php`. You can copy the whole function to your plugin file (or your theme's functions file), rename it `my_die_handler`, and customize it from there. | stackexchange-wordpress | {

Creating a Search Array From Multiple Tables

How to reset a custom theme
After making a lot of little changes to the current custom theme [ [zeeBizzCard]]( I'm using, I want to reset it back to it's original style. Being new to WP, I didn't make a backup of the default theme and can not find a quick and easy method of reseting the theme.
Have I missed something, or is there no "reset" options for downloaded themes?
Thanks | If you look into the file `includes/admin/theme-admin.php` you’ll see that the theme’s options are stored in `'themezee_options'`. You can either delete these options per database manager or per a plugin.
If you aren’t familiar with database operations, copy the following code into a PHP file, install it as plugin and activate it once. Then deactivate it immediately.
/**
* Plugin Name: Reset zeeBizzCard options
*/
register_activation_hook( __FILE__, 'reset_zeebizzcard_options' );

Maintaining plugin addons while upgrading
I'm developing a freemium wordpress plugin where "skins" will be available for purchase to customize the appearance of the plugin.
If I commit an update to my plugin, it sounds like the contents of the "skins" folder inside of my plugin would be removed (since the skins don't come bundled with the core plugin), and the user would lose any skins they may have purchased.
What can I do to circumvent this issue? Should I look into moving the skins folder temporarily while upgrading, or somehow utilize the database?
Thanks! | I'd suggest either using the database if possible or using a folder outside your plugin folder. A sub-folder of the `wp-content/uploads` appears to be a popular choice, as it survives updates/upgrades. | stackexchange-wordpress | {

Create/Edit/Check cPanel Email Accounts from Wordpress
I need a plugin (or other) recommendation to allow users to create email accounts, as well as change their passwords and check their email using WordPress.
I have a multi-author baseball website and I would like to allow authors to create their own email addresses at my domain name, if they like.
That being said, I do not want to create the email addresses myself. I do not want/need to know the authors' passwords to the accounts and want them to know I respect their privacy.

1. Open your code editor
2. Open up search and replace
3. Select the plugin folder to search
4. Search the source code for `/cpanel_ops/`
5. Replace it with `/cpanel-operations/`

Moving from one host to another - cannot access the dashboard
I'm having a problem with my WordPress installation. I'm trying to move it from one host to another (switching hosting providers for my sites). I was following the instructions given here, and everything went smoothly except for one little thing: I can no longer access the dashboard.
Similar to this (unanswered) question: moving server can not login
The site works, I can see all the posts, all the uploaded pictures, all the comments and tags - everything is there and available. I just cannot access the dashboard. Password recovery didn't help, and doesn't seem to be the problem. It doesn't complain, just clears the fields when I click "log in" and stays on the login page.
Note that the domain name doesn't change, I switched servers, but the domain remains the same.

To delete all these comments is it sufficient and safe enough to do:

What is the difference between these two methods of writing $ instead of jQuery in WordPress

// console.log($);
})( jQuery );
... Which I found here
and
jQuery(function ($) {
/* You can safely use $ in this code block to reference jQuery */

(function(someVar) {
// Inside the closure, someVar == "test"
})("test");
Basically, you're manually passing jQuery into the closure by referencing the `jQuery` object externally and aliasing it to `$` inside the context of the closure.
The second pattern is unique to jQuery. It's one of the library's shortcuts to the DOM ready event. The following calls are all equivalent:
jQuery(document).ready(function($) {
// Use $ inside here like normal
});
jQuery.ready(function($) {
// Use $ inside here like normal
});
jQuery(function($) {
// Use $ inside here like normal
});
In all three examples, you're also passing the `jQuery` object into your function as the variable `$` so that it's available within the local scope. | stackexchange-wordpress | {

What is the right way to make custom main page?
I am making a custom theme and I want the main page to be a gallery, not a blog,
is it right to change `index.php` to a gallery page (content wise) or should I use another page? | There are definately a few ways of achieving this functionality. I assume by "main page" you mean the home page...
a. Create a new page called "home" b. In your site settings change your homepage to point to the "page" home, rather then grabbing your 10 newest posts. c. Now you have a page hook which you can build a custom template for in one of two ways.
1.) Use wordpress "custom page templates" to create a new template and apply to the new "home" page in "edit page" <
OR...
2.) You can simply create a new file called "page-home.php" (ensuring the slug of your new home page is "home") and WP will use this page template instead....
Solution 2 is more streamlined for progamming if your clients don't need to apply templates themselves.

How can I attach images to a post from the media library?
Currently, there is no way to do this in a vanilla Wordpress install. Is there a way to retroactively attach an image from the Library to a post?
EDIT: Ah, let me clarify — when editing a post, and clicking the "Insert Media" button, I see no way to add past media. I can insert it into the post, but not add it to the post gallery. | This is not something that is currently supported in WordPress. There's some discussion about it here: <
One plugin which does enable this functionality is:
<
This plugin does a few extra things, but one option it provides is that after clicking "upload/insert" and going to the media library tab, you can tick check boxes beside images and choose to attach them to the current post.
There's also an old thread on WordPress support forums which pertains to adding a small bit of code to your functions.php file to enable this functionality but I think that only works within the Media Library section, not when in the Upload/Insert thickbox, so the above plugin might be your best bet.

term_exists returns NULL

Two Custom Post Types, Share Two Taxonomies
I have two custom post types
* Hotels
* Things to do
And I have two taxonomies
* Activities
* Regions
So when a user sees a **Hotel** (custom post): the user can then see
* the region it's in
* what activities they can do.
_And viceversa as well_
When the user sees **Things To Do** , he can see in which **Region** it is and what **Hotels** have the same type of **Activity** nearby.
The problem if I use two custom post type and create a taxonomy for it, I have no way of discerning each taxonomy related to a custom post:
> Example: **Hotels** in X **Region**
I would get both the **Hotels** and **Things to do** custom post, within that taxonomy.
* * *

* Hotels (taxonomy is _continent-hotels_ ) values: Europe, Asia etc
* Places (taxonomy is _continent-places_ ) values: Europe, Asia etc

force enqueue script to be first in order of prominence
I have a few scripts which are being enqueued,
the problem is that I want to force the order of prominece to which these scripts are loaded. There is one in particular which is loaded from a plugin before the theme ones which requires jquery however the plugin does not require jquery (bad dev on the plugin but I'd rather not touch 3rd party code for futureproofing reasons)
is there some way to mess with the enqueue order at runtime?
Thanks very much | You just need to enqueue your scripts before plugin does it. You can do it by setting priority to 0 for your hook. For example, do the following:
add_filter( 'wp_enqueue_scripts', 'wpse8170_enqueue_my_scripts', 0 );
// or if you enqueue your scripts on init action
// add_action( 'init', 'wpse8170_enqueue_my_scripts', 0 );
function wpse8170_enqueue_my_scripts() {
wp_enqueue_script( 'myscript', ' array( 'jquery' ) );
// my else scripts go here...
}

Custom row action on custom posts list page causes a wp_die?

when does output of get_user_count turns into an array?
**question**
WHEN does the integer output of get_user_count() turns into an array ?
**background**
The function get_user_count() in ms-functions.php returns an integer (it calls get_site_option('user_count')
The function wp_version_check() in update.php stores this integer in $user_count on line 55
Directly after that on line 73 it calls this integer with $user_count['total_users']
**reason for asking**
On my network admin pages I get the error:
_`Warning: Illegal string offset 'total_users' in /opt/htdocs/html/wp-includes/update.php on line 75`_
So I need to understand where I need to look (probably something I did somewhere)
see also: < | Via:
* <
* <
* <
I find:
1. Normally it would return an array from the cache
2. Meaning the return value of get_user_count() is different than in the php doc above it
3. But... if the cache does not contain it, it will return an integer leading (in my case) to an warning (requesting an array value from a string) BUT somehow not leading to a warning with many others (assuming they still have an array as return value, even if it does not contain a value)
I found out that when on PHP version 5.4 or later it will throw this warning. Previous versions will not throw this warning, related, see example 2 on <

Update Wordpress automatically on its own
Is it possible to update Wordpress automatically so that when there's a new version of Wordpress, my installation will update itself automatically without me having to login to admin > update ? | Yes it is. Though perhaps not in the way you might be thinking.
If you check out some of the shared hosting sites, many of them have the capability to automatically update your WordPress site.
Of course, as Milo has said, it can be rather disastrous too. Especially on a site with lots of plugins installed.
So the answer is to have an **external script** that does a "manual" upgrade as per the WordPress documentation.
Firstly, the script needs to check to see if an upgrade is needed. The code is always available as " so you could write a PHP script that checked if an HTTP head request to that URL returned a 304 (not changed) or a 200. If the later, you would start the download and then ...
You _will_ want to make the script do a backup of both the site and the database _before_ doing the upgrade of course.

Wordpress : Explain Plugins & Theme string value in database
i have installed wordpress and i i have installed couple of plugins and i have got two themes already came with wordpress.
What i am asking about today is : what does the Plugins & Theme string value in database mean ?
Example [When plugins are active] , there is a value on table of :
a:3:{i:0;s:19:"akismet/akismet.php";i:1;s:9:"hello.php";i:2;s:37:"one-click-logout/one-click-logout.php";}

a:2:{s:12:"twentyeleven";s:7:"/themes";s:9:"twentyten";s:7:"/themes";}

Further explanation is not really WordPress specific, but here you go -- the 's' is the length of the string representation of the succeeding array element (the length of the string in quotes). I.E. in
`a:2:{s:12:"twentyeleven";s:7:"/themes";s:9:"twentyten";s:7:"/themes";}`

{

Does WP always makes 301 redirection?
We rented a SEO specialist for our site, and he says that we have to do some changes in site structure before he starts his work.
The first is, that now most pages have 301 redirection.
For example:
* `mysite.com/2010/12/02/postname/?p=5500` is redirected to `mysite.com/2010/12/02/postname/`
* some posts are redirected from `mysite.com/2010/12/02/postname/?=12786` to `mysite.com/2010/12/02/another-postname/`
* some posts have redirection from `www.mysite.com/2010/12/02/postname/Mysite/?p=32123` to `www.mysite.com/2010/12/02/another-postname`
I would like to know:
1. Why does it happen?
2. Is it a normal WP behavior?
3. How can I change it?
4. Is it really important to avoid this for good SEO? | Yup, that is very normal.
If you don't want WP to redirect anything. Simply remove the action by adding this code into your working template functions.php file.
`remove_action( 'template_redirect', 'redirect_canonical' );`

Getting trackpacks/pingbacks for a post via wordpress?
Is there a way for someone to query the wordpress API of a blog in order to get the pingbacks/trackbacks for a post?
E.g a blog is hosted on example.com. I want to query example.com's wordpress API to get a list of its posts, and for each post I want to query it, to get a list of the trackbacks.
Is that possible? | You may be able to find that information in the blog's feed, i.e. example.com/feed/ I'm unsure if the trackback would be public, you may have to view the Comments section of the WordPress blog. | stackexchange-wordpress | {

Is there a default template file for child pages / subpages?
This seems like a very simple question. I'm looking for something like sub-page.php or page-child.php where I can do some different things on the child pages of my theme.
They are different enough in design and content that I'm having to use a lot of php or the CSS .page-child class to do all the dirty work. I'm looking for a simpler method.
One caveat - I would like this to happen automatically so I don't have to tell the client "make sure to always select the 'subpage' template when you create a subpage!" which is precarious.. | There is no specifica template for child pages, but you can do this pretty easily with the get_template_part() function.
First create a file called "content-child.php".
Second create a file called "content.php".
Next, inside of page.php, place this:
if( $post->post_parent !== 0 ) {
get_template_part('content', 'child');
} else {
get_template_part('content');
}
Anything that you want displayed on a child page will be placed inside of content-child.php. Anything you want displayed on non-child pages will be placed in content.php. | stackexchange-wordpress | {

Per theme plugins?
I'm building a plugin that heavily modifies the commenting section of a blog page. It think that I cannot do this in a way that works with all themes — some CSS has to be tweaked, depending on the particular theme in use.
I'd guess that in the future, the plugin will also store some data in the database. So I suppose it should be a plugin, not a theme. (?)
Hence these questions:
1. Is it possible to in some way indicate that a plugin works with only this and that theme?
2. And then release some fairly simlar versions of the plugin, each version tweaked for a specific group of themes?
3. Or are plugins supposed to work well with... all themes in existance?
4. Can you think of some solution other than per-theme-plugins and/or forking-and-modifing-existing-themes? Perhaps child themes? But, no, then it would not be possible for users-of-my-child-theme to create their own child themes? | There is no way to bind it to a specific theme unless you contact theme authors and they link back to you at some point (on theme activation with yellow message on the top or in their admin menu etc). As you suggested yourself, a plugin is supposed to work with any theme.
Theme and plugin markets could handle this by indicating that their plugins work with their themes only but this is a corporate restriction and cannot be applied technically.
What could be do is when you release something, you could name and describe it so it's pretty much obvious (such as here - < ). Also, in your plugin you could check for the currently activated theme (see get_current_theme ) and output some error message from within your plugin that it's inappropriate choice. | stackexchange-wordpress | {

file_get_contents Not allowed in Themes?
I'm using `file_get_contents` in a theme development (in a widget of the theme). However the theme check plugin gives me following warning:
WARNING: file_get_contents was found in the file file.php possible file operations.
Line 49: $data = file_get_contents ( '

Don't use `file_get_contents` to download web page. WordPress has HTTP API for such needs. In your case, I would suggest you to use `wp_remote_get( ' );` function instead of `file_get_contents`.

Do all wordpress themes a similar class name for content?

.entry-content
if not then how would I go about referring contents for all theme using jQuery?
e.g $j('.entry-content').css('color','red');

What hooks/filters are there to alter selected terms on post save?
Very simple, where would I hook/filter to alter the users selection of terms when they save a post (Update or Add)?
I need to hook in all instances; such as when saving a post via AJAX, saving when JavaScript is disabled and a normal POST is done and when posts are saved via quick edit. | It is always `'save_post'` (or `'wp_insert_post'` immediately after this). In `$_POST['tax_input']` you will find all the terms for all taxonomies associated with the current post.
Example:
'tax_input' =>
array (
'location' =>
array (
0 => '0',
),
),
To change the terms you have to call `wp_set_post_terms( $post_ID, $tags, $taxonomy );` manually, just changing these values will not work because they are set when the actions fire.
For an existing post that is updated you can hook into `'edit_post'` and `'post_updated'`.
Parameters for all these actions are `$post_ID, $post` in this order. For `'post_updated'` there is a small change: `$post_ID, $post_after, $post_before`. | stackexchange-wordpress | {

Make 'Howdy, [name]' function as log out button

Storage of array in settings
I'm creating a plugin that will store some simple layouts to be used in shortcodes.
The shortcode usage will be similar to `[shortcode layout="name"]`
With this mind I'll need to store each layout in the array as a key/value setup
Key = layout name
Value = layout markup
I'd like to store these in settings however I'm not sure how to go about it. How can I create a settings page that allows addition and editing. Normally my settings pages use code as follows and automatically wires into the api.
<input type="text" id="company_name" name="wpv_settings[company_name]" value="<?php echo $wpv_settings['company_name']; ?>" class="regular-text" />
However, I can't find how to go about this when the setting is an array of key/values.
Can anyone point me in the right direction of how this would be done? | Since the layout names are dynamic, perhaps it's better to store them in a numerically indexed nested array? Something like:

Where should a plugin or widget cache its results?
_Where should a plugin cache its re-usable results?_
I have read the code of several well-used Wordpress plugins, and it seems that the answer is not consistent. I have written several plugins myself, and I store things in a cache directory. But I just picked the location of the directory out of a hat, and my code creates the cache directory if it doesn't exist. This seems arbitrary.
I know there are plugins that do caching. Suppose I don't want to use a plugin. I find that relying on the filesystem to cache results is easy for maintenance, diagnostics, and performance.
Is there a good, more-or-less standard approach, or a blessed approach, to choosing a filesystem location for a cache? | > I find that relying on the filesystem to cache results is easy for maintenance, diagnostics, and performance.
Please note that this might be true in some (maybe even most) circumstances, but not **all** of them. If your code is meant for anything beyond personal usage you _don't know_ with which file system and hardware will it be used and how will it perform there.
WP is engineered to use database for storage of textual data, that is more typical and logical first choice than file system.
> Is there a good, more-or-less standard approach, or a blessed approach, to choosing a filesystem location for a cache?
`wp-content` folder is meant as a place for files uploaded or generated during operation. Plugins that use file cache should create folder for it in there. Note that WP is flexible about most of folder structure and it can be easily renamed/relocated from defaults - use appropriate functions to determine that rather than hardcode default path. | stackexchange-wordpress | {

_deprecated_argument for constants
i'm working on updating a theme and previously it had used a lot of php CONSTANTS to set up some options as true or false. we're going to be updating these "decisions" to use add_theme_support() instead. is it appropriate to use the _deprecated_argument() function to tell child themers that these constants are deprecated? if not, what is the best way to trigger a deprecation warning for a constant? | Unfortunately there is no way to trigger WP deprecation warning for PHP constants.
What I can suggest - to use your constants and "theme support" options together. First for backward compatibility, second for customization facilities. Your theme will have to rely on "theme support" options only, and keep constants only for child theme.
The trick is in the way of declaration such constants. You have to define your PHP constants based on what has been added to support by theme.
After updating your theme, you need to let people know that you don't use PHP constants any more and you will remove PHP constants in further releases. You can place such information on a site via which you distribute your theme. | stackexchange-wordpress | {

Separately formatting date elements
I am trying to achieve the following look in the time format:
!enter image description here
I have for now several issues,
First is that the month and year are not displayed at all, I use `<?php the_date('D'); ?>` `<?php the_date('M'); ?>` `<?php the_date('Y'); ?>` for start and only the day is shown,
Second - Are there WP functions I can use to
* Get the month in 3 cap letters?
* Get only 2 last digits of year?
Or I have to use my own PHP functions for that?
Also, it must be hard-coded in the theme, because otherwise it will mess up the design.
**Update**
I used `<?php echo get_the_date('M'); ?>` and I got all the times, but isn't `the_date` meant exactly for that? | I believe all the info you need is in the PHP Manual for Date/Time. Also, it is recommended that you use `get_the_date();` instead of `the_date();`
> **Get them month in 3 cap letters?**
`M` is the right format character that outputs a short textual representation of a month (3 chars). Why can't you use CSS to capitalize all the three letters? I mean, `text-transform: uppercase;` should do it.
> **Get only 2 last digits of year?**
Use the small `y`. It outputs two digit representation of a year.
**EDIT (to answer the updated question)**
The function reference for `the_date();` in codex has a **special note** that says:
> When there are multiple posts on a page published under the SAME DAY, `the_date()` only displays the date for the first post (that is, the first instance of `the_date()`). To repeat the date for posts published under the same day, you should use the Template Tag `the_time()` or `get_the_date()` (since 3.0) with a date-specific format string. | stackexchange-wordpress | {

Custom image size vs CSS sizing
I am developing a theme which will have 2 configuration options for the slideshow in the header; a full width version and a half width version. The theme is also responsive and so I am trying to optimize it as much as possible from a speed point of view. I am trying to decide which approach is best.
1. Use `add_image_size()` to create a new image size to use for when the user selects the half width configuration
2. Use the full width images and re-size them using CSS
The advantage the new image size is that the slider images would be smaller, this is positive since the theme is to be responsive, however it means that every image in the library now will have an extra image created, even though only a small few of these images will actually be used in the slider.
Which would be the best approach, or is there anything else to consider? | The best approach is to serve the smaller image sizes, that is what matters to the end user. If you do the math on something like 5 slider images (large ones) you will see a pretty significant difference. Image sizes are in most cases the largest request.
The downside is simply having more storage on your server, but that doesn't effect the end-user nor is it expensive. | stackexchange-wordpress | {
