In a MS install, can you allow different users to have their own themes?
Is it possible in a MS install to allow network site admins to edit their own themes? For example, I would like to give everyone access to theme ABC, but if one user edits that theme, they seamlessly create their own instance of the theme, so no other user's theme is affected. I believe the short answer is "no" so I'm wondering if there are any good ideas about how to implement this kind of system. | Well as WordPress is open source, if you have control of your server, you can technically do anything :-) Depending on your skill set, that may or may not be feasible.
A low tech solution would be to create a copy of the theme ABC for each user. Change the folder name, and change the **Theme Name** in the comment at the top of style.css to personalise it to each user (e.g. "ABC for Bob", "ABC for Clare"). The codex on child themes is a good starting point for information about this.
I'm not aware of any API calls to detect changes through the theme editor, so I think you'd have to patch the core WordPress install. I had a brief search for where this might be. Using exec() to copy the theme directory would be pretty simple, but the user interaction and updating which version of the theme is being used could make it a bit more complicated.
Of course this is further complicated by the fact that the 'edit' function on a multisite is only available to the network admins. | stackexchange-wordpress | {

How to call uninstall.php?
I am a newbie in WordPress... I have created my plugin... now i am creating uninstall.php file for uninstall my plugin...
this is my code of uninstall.php
if(!defined('WP_UNINSTALL_PLUGIN'))
exit ();
//here I am dropping my table and options...
I don't know how to call uninstall.php? from where to call? from where i can uninstall my plugin...
I know register_uninstall_hook() but when it get triggered?
Thanks in advance | Uninstall hook and `uninstall.php` file are two alternate ways to implement uninstall functionality, they are independent of each other.
When `uninstall_plugin()` is called it checks for `uninstall.php` **or** hook (in this order).
So if you are using file approach there is nothing special you need to do to call it. WordPress looks it's up by name and runs on uninstall natively. | stackexchange-wordpress | {

Change the name of an installed plugin
I have installed a third-party plugin for my wordpress site. What I want is to rename that plugin so that it matches my purpose for installing it. Is it possible?

plugin generated 751 characters of unexpected output during activation
I made a custom plugin for my wordpress admin for view user detail. This plugin is working fine after showing this error but the main issue is by this plugin , when i try to open some link the page went blank. I dont know why and what is this error..Searched on internet but unable to resolve this issue. Your help would be appreciated...here is the fulll error comes when i activate this plugin...I
**The plugin generated 751 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin** | Your plugin is causing some errors, but not fatal ones, so plugin works, but as the error messages says, it can cause some problems, i.e. the feed that can output the plugin error so not valid xml content, or when somewhere in the code there is a redirect once _"headers already sent"_ it fail.
If you are asking yourself why the plugin works despite that error, it's because not all errors are _fatal_ (make script die), just as example see following code
if ( ! $number ) {
$number = 1;
}
echo "My number is " . $number;
If you have a code like this in your plugin it will works, but it causes an error because in first line there is a variable that is not defined anywhere.
This is just an example, but there are **a lot** of situations like this where code works but causes errors.
When you develop a plugin, activate **debug and error log** and also I suggest to use some debug tools: some are really useful. | stackexchange-wordpress | {

get post types and plugin order
I write a simple plugin to get all post types by using get_post_types. But it does not work.
$customPost = get_post_types(array(), 'object');
it returns default post types of wordpress.
When i install Woocommerce plugin, it does not show the custom post types of woocommerce ?
Does it relate to plugin order ? | Post types in WordPress are not _saved_ some where, they are _registered_ everytime you request a page.
So to get all post types, you have to wait untill all post types are registered.
Normally, all post types are registered before the hook `wp_loaded` is fired.
So change your code in something like this:
add_action( 'wp_loaded', 'my_get_all_types' );
function my_get_all_types() {
// if you want only custom post types use '_builtin'=> false in the arguments array
// 2nd argument should be 'objects' not 'object'

Disable the visibility options in WP

$_SERVER['SERVER_NAME'] in WP_SITEURL
My client has two domains, and wishes to split a product catalogue over them. They want to have a shopping cart that is shared over both, i.e. a shared session over the two domains, this is solved in principle at least, and not the point of this question.
Am using WooCommerce (no choice in this).
Since the products need to available to be ordered in one transaction, they need to be in the same database, so I don't think a normal multisite install is going to work.
I'm hoping therefore to be able to use a single WP install, and simply put `$_SERVER['SERVER_NAME']` in `WP_SITEURL` & `WP_HOME`.
I've seen very few references to doing this, so I'm nervous about possible unforeseen consequences.
Can anyone reassure me, or perhaps tell me why I shouldn't do this? | Personally, I make them default to the HTTP host:
define('WP_HOME', ' . $_SERVER['HTTP_HOST']);
define('WP_SITEURL', ' . $_SERVER['HTTP_HOST']);
There are no caveats for single WP installs. It's in fact very convenient when testing changes in a dev.example.com subdomain, in the sense that it allows to use the same database before rolling out a change on a live site.
Don't do this in multisite installs, however — especially you plan want domain mapping. :-) | stackexchange-wordpress | {

bloginfo() vs get_option?
What's the difference between:
`bloginfo('name');`
vs
`get_option('blogname');`
The parameter is just an example, but I see no differences in terms displaying what I want.
Are there any particular differences? Or are they just for semantic reasons.
Thanks in advance. | The two functions output exactly the same thing.
From the Codex entry for `get_bloginfo()`:
> 'name' - Returns the "Site Title" set in Settings > General. This data is retrieved from the "blogname" record in the wp_options table.
From source:
case 'name':
default:
$output = get_option('blogname');
Neither `get_bloginfo()` nor `bloginfo()` do any sort of sanitization or escaping; so both `get_bloginfo( 'name' )` and `get_option( 'blogname' )` return exactly the same value. | stackexchange-wordpress | {

How to create a category or tag available exclusively to the admins and not to the users?
I would like to create a category or tag name that is available only to the admin(s) and not to the authors.
For example, I would like to create a category or tag called `Exclusive Content`.
Now only admins should be able to add this category or tag to their posts. Other users should not be able to see it or use it.
Is it possible? | Sure, you can restrict access to a tag with the following code:
add_action('save_post', 'remove_tags_function', 10, 2);
function remove_tags_function( $post_id ){
if(!current_user_can('manage_options')){
$post_tags = wp_get_post_terms( $post_id, 'post_tag', array( 'fields'=>'names' ) );
$pos = array_search( 'ExclusiveContent', $post_tags );
if( false !== $pos ) {
unset( $post_tags[$pos] );
wp_set_post_terms ($post_id, $post_tags, 'post_tag');
}
}
}
So, with this code, whenever a normal user adds the tag `ExclusiveContent`, it will be removed upon save _unless_ if the current user can `manage_options`. This code should be added to your functions.php file. You can find this file in your theme's folder. | stackexchange-wordpress | {

Set colors depending on category
I have this function which outputs the last 6 posts of categories 1 and 2.

<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><strong><?php the_title(); ?></strong></a><br />
<em><?php echo substr(get_the_excerpt(), 0,110); ?> ...</em>
</li>
<br />
<?php endwhile; ?>
</ul>
What I'd like to do is have the link to the article (for instance) red if it's from category 1 and green if it's from category 2. Can you help me? | Setting aside that you're incorrectly using `query_posts()`, the easiest solution is to add a call to `post_class()`, to output post-specific classes, including `.category-{ID}` and `.category-{slug}`:
<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<li <?php post_class(); ?>><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><strong><?php the_title(); ?></strong></a><br />
<em><?php echo substr(get_the_excerpt(), 0,110); ?> ...</em>
</li>
<br />
<?php endwhile; ?>
Then, you can use CSS to target `li.category-{ID}`. | stackexchange-wordpress | {

What is the best way to mimic a search query within a plugin

Wordpress Importer Tries to save media files to wrong site folder
I am importing from one WordPress multisite instance to another, using Tools -> Export to generate a WXR file that I then import with and Tools -> Import . I receive the "Failed to import media" message for all files.
When I look at the apache log(on the production server, which is importing) I get:
` [Wed Nov 13 11:05:30 2013] [error] [client 10.11.1.13] client denied by server configuration: /var/vhosts/wordpress/html/wp-content/uploads/sites/10, referer: < `
The path on the test server I am importing from is: /var/vhosts/wordpress-test/html/wp-content/uploads/sites/10
The path to the new site on the production server is: /var/vhosts/wordpress/html/wp-content/uploads/sites/6
I do not understand why it is trying to get to that site on prod | I've created a patch that will work around this issue. This patch is for WordPress 3.6.1. It is a hack, not something that should be taken very seriously except that it points out where the problem may be. I don't know PHP, but was able to trace it back to this point before giving up. I expect someone with more familiarity with the WordPress code base could figure out what the problem is once they see the patch and see what code is being modified.
I did notice that the code is doing a lot of checks against the IP of the remote server. I'm not sure the justification for checking whether the remote server is on a private network, but that may be part of the issue. The server we exported from is on 10.10.2.16, while the server we import on is 10.10.1.206. Both are on the same private network.

Is it possible to create an action hook using do_action() within add_action()?
Is it possible to create a new action hook like `do_action('my-hook-name');` inside a call to `add_action();`?
I'm aware this code doesn't work, but I was thinking something along the lines of... `add_action('init', do_action('my-hook-name'));`
or
Is the only way to actually add a callback function to `init`, then inside my callback function create my hook?
add_action('init', 'my_callback');
function my_callback(){
do_action('my-hook-name');
} | Creating an answer based upon responses via comments on original question of: Is it possible to create an action hook using do_action() within add_action()?
Yes it is possible to create an action hook using `do_action()` on a call to `add_action()`.
For clarification, the following code does **NOT** work:
`add_action('init', do_action('my-hook-name'));`
As stated by `@IvanHanák` in the comments to the original question asked; It is possible to create an action hook using `do_action()` on a call to `add_action()` by using anonymous functions.
An example of creating an action hook using `do_action()` on a call to `add_action()` using anonymous functions:
`add_action('some-existing-hook-name', function(){do_action('my-new-hook-name');});`
However, it should be noted that using anonymous functions can make it difficult to debug or remove hooks. | stackexchange-wordpress | {

Display articles related to a custom field on a page
I have a little problem to display some articles related to a parent page. I explain.
On the first hand I have a page with a model template. On the wordpress editor part, I create a custom meta field call "cat_page". This meta must be the same as the article related (view more below). This template has a classic loop to display to content of the page :
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php the_content(); ?>
and below I need to display the articles who have the same category name as the page.
if ( get_post_meta($post->ID, "cat_page", true) == the_category() ) : ( have_posts() ) : while ( have_posts() ) : the_post();
It's only what I think it should look, because I have tried several things but I don't know how to proceed.
Image (if it can help)
Thanks in advance. | If I understand well, you have a page template, and you want to use this page template as a category archive.
The term to show is in a page meta field with key 'cat_page'.
If I'm right, in this page template use:
the post(); // being a singular page the 'while' stuff is useless
the_content(); // this will show the page content
$cat = get_post_meta( get_the_ID(), 'cat_page', true ); // get the category to display
if ( $cat ) { // if category is setted in page custom field
$query = new WP_Query( 'category_name=' . $cat ); // run the custom query
while ( $query->have_posts() ) { $query->the_post(); // run the custom loop
// your post loop code goes here
}
wp_reset_postdata(); // reset the post data after the custom query

Add a YouTube or Vimeo video as a post attachment?

get_post_meta() retrieves meta from a specific post on pages, not the page currently viewed

Custom Post Types. Are there any disadvantages/advantages in using a plugin to develop them?
There are a few plugins which can assist you in building your CPT's, and these can usually handle your taxonomies and sometimes postmeta also. Some even take it further than that.

**Here are some of the plugins I'm referring to**
* Custom Post Type UI
* Types
* WCK
* Custom Post Type Maker
**Here's my Advantage/Disadvantage list**
_Advantages_
* Quicker and Easier
* Developers have hopefully considered security so no need to worry about nonces or protecting the database etc
_Disadvantages_
* Might be a performance issue for some applications
* Depending on development to continue.
* Possibly Less Flexible
Does anyone want to add to or take away from this list? | I think there's no really huge difference, you choose the tool that you feel most comfortable yourself. Plugins have the drawbacks you mentioned, and doing them from scratch can be a bit slow and tedious.

Get an uploaded attachments local server path?
All the wordpress functions for retrieving media details seem to give you the web url of a file uploaded. I want to the local server drive/folder path, ideally relative to the install of wordpress. I have the attachment id value to hand so can parse that to a function, if only I knew what it was.

Custom headers in WordPress, are there also custom footers?
I’m new to WordPress. I saw a custom header file in the `inc` folder of Twenty Twelve theme. I understand that we can use this custom header in any custom page template instead of header.
I have a doubt now, is there any custom footer that also can be used? Why this custom files should be stored in `inc` folder? | You can take a look at Custom Headers documentation for information about it.
There is no "custom footer" feature, well because WP only has "custom header" theme feature and it isn't named/scoped to handle arbitrary custom-something.
> why this custom files should store in "inc" folder?
This is just an implementation detail of specific theme, it's not required or standardized in WordPress. `inc` is short for `includes` and is typical name for folder containing PHP files (other common folder names being `php` and `src`). | stackexchange-wordpress | {

Vagrantpress + composer
I was looking at the roots.io blog, where I learned about Vagrant and Composer which in combination seem to give you a more intelligent development environment and dependency management system. I choose to get and install Vagrantpress since it seems like the easiest way to get started with wordpress + vagrant. The plus of Vagrantpress is that it installs Wordpress and all its dependencies for you. As I understand Composer in adjunction with Wordpress, is that the easiest way to combine the two is to use the Outlandishs WordPress Packagist. Now my question is, how are people using Composer and Vagrantpress tougher? How does your setup look like? Are there any good examples of composer.json file + Vagrantfile for Vagrantpress?
/PS: If someone with enough rep could create the Vagrant and composer tags that would be great. No relevant tags really exist, but I hope the question is relevant enough. | Unfortunately you can't use Vagrantpress and Composer directly together easily. Half of Vagrantpress is the WordPress setup itself which isn't compatible. If you still wanted to leverage the base work Vagrantpress has done with PHP, Apache, MySQL etc, you could fork it and modify their WP module found here: <
It would still require a decent amount of changes though since you'd need to install Composer, modify their wp-config.php (the ones outlined in the Roots blog post), and run `composer install` instead of downloading the WP tar.gz.
It might just be easier to built a custom LAMP style Vagrant file with < and then write your own manifests for the WP/Composer part. | stackexchange-wordpress | {

Undefined index: id, when I save the options

Why is get_pages() returning a boolean?
I have created a custom post type that I want to use to allow people to add an arbitrary number of sections to the homepage of my theme. I want to loop through all posts of that type and include their contents in the page. My problem is that calling `get_pages()` with `'post_type' => 'home_section'` seems to be returning a boolean, not an array.
Here is the code I'm using to test:
<?php
$hp_sections = get_pages(array('post_type' => 'home_section'));
echo '<!-- $hp_sections type: ', gettype($hp_sections), ', value: ', $hp_sections, ' -->';
?>
When I view source on my page I get:
<!-- $hp_sections type: boolean, value: -->
I'm pretty new to both PHP and Wordpress so I'm assuming I'm making some sort of dumb mistake. I'd like to know both what is wrong with the above code and what the recommended way to get all pages of a given type and iterate over them inside a template is. | Historically I've had better luck using `get_posts()` over `get_pages()`. Especially in the case of a custom post type, I'd recommend using something like
$args = array(

);

instead of using `get_pages()`.

Videos via the video shortcode are always 640px wide?
I've run into a particular problem with the Video Shorcode of WP.
I can't seem to change the size of the player with the attributes of the Shortcode.
This happens on multiple sites with multiple templates (Twenty Thirteen included).
Here's the visual :
!enter image description here
So I have 2 video tags, one with a width of 720 and the other with a width of 930.
!enter image description here
In the page, they are both the same size (640px wide) even if they still have place in their container (see orange box by the developper tools, meaning that there's untaken space on the right of the first video) and they both had different sizes over 640.

woocommerce product attributes

site-description css is overriden
I'm trying to change the site-description color of my twentythirteen header to #220E10.
My style.css file reads :
.site-description {
font: 300 italic 20px "Source Sans Pro", Helvetica, sans-serif;
color: #220E10;
text-align: center;
margin: 0;
padding-bottom: 25px;
}
However, the color of my header (viewable here) remains #FF6000.
I know the css file is the used as a source for size, font and other details, since I can effectively change those and see the results happen. The color will not change however.
I suspect the override has something to do with the basic Wordpress editor which allows you to change the color of your header text.
I can't seem to be able to identify the location of the source css being used for this color. The #FF6000 color is not present in my style.css file, except for that intentional navbar.
Could you help me edit the site-description to a different color ? | There's a CSS rule being output in the `<head>` of that document that is defining the color, _after_ your stylesheet is included (thus overriding it). Take a look at the options for the theme, and see if there's a way to set the color through the admin area.
If you want to override JUST the description, add `!important` to the color rule in your css file. It's an unfortunate solution, since `!important` rules can cause all kinds of havoc during maintenance phases... but the other option is to dig into the theme files and try to change the options settings to two color settings, or change the output in the theme header so it only defines a color for the title, instead of both the title and description. | stackexchange-wordpress | {

Woocommerce Attributes pulling in wrong data

Confusion on how to display custom field data
Hey I'm new to WordPress. I've looked at the codex and other topics here, I just don't get how to display my custom field, which I have set in the area under my post editor. The name is `MyField` and the value `This is my custom post text`.

Weird characters in title if it contain “ ”
If my post title contain `“ ”` all the title stored in the database title column in weird characters like this
`"الأورومتوسطى للشباب" تبدأ تلقى استمارات أنشطة الجمعيات الأهلية`
I searched more & more but all i found is some advices to change the table encoding to `UTF8` it is already `UTF8`
After some tests i found that the problem is came from `feedwordpress` plugin not from WordPress itself
How to solve this? | The Solution is:
every normal character stored in weird starts with `&#` ends with `;` like this `٪`
So you can simply 1-open you dreamweaver
2- new HTML file
3- code tab
4- delete all the code in it
5- put one weird code like this `٪`
6- design tab
7- you can see the original character here
8- execute this sql query in `PHPMyAdmin`:
`update en_posts set post_title = replace(post_title, 'one weird chracter code', 'original character');`
9- repeat this method for every character
10- save your sql queries in txt file
11- execute all this queries every few days
The benefits of this cleaning method:
1- for big wordpress installation this will decrease your database size & speed up your site performance
2- if you using `getposts` or `wp query posts` to execute posts by `s=keyword` all the weird posts will not shows in your query
