Display a list of users with avatar filterable with alphabets
I'm trying to create a page which should display a list of users with the role "Author" only and exclude all other default and custom roles.
I also want them to be filterable by alphabets, so if I click on "A", or "B", and so on, the users starting with that alphabet should show on the page.
I tried to use wp_list_authors but that's very limited to what I need here. (code below)
<ul>
<?php wp_list_authors('exclude_admin=1&optioncount=1&show_fullname=1&hide_empty=1'); ?>
</ul>
Any idea how this can be done or any plugin for this? | Alright, I've got a plugin here which sorts it out.

Auto Stock Update after Order cancel from Admin of Woocommerce?
I recently implemented Woocommerce and in trial session I found following issue:
**1.** Initially, I provide 10qty for Product1. **2.** place a Dummy Order from front-end of 10qty of that Product1. **3.** Then After that I see Product1 is Out of Stock. **4.** From Admin of woocommerce, If I cancelled that dummy order or reduce the product qty on that order, It Doesn't Update the Stock Qty of that product1.
And I still see the Out of stock label on that product even after that order has been cancelled which reserved this qty.
Hence is their any way to Auto-Manage this Stock Updates between orders and Inventory. | Sorry to Trouble this Slept world of Wordpress. I got My answers From Awaked wordpress world,directly from Author of Plugin here: < | stackexchange-wordpress | {

How to get the url to tag & category base set by the user?
I'm searching for half an hour now on how to get the url/permalink base in Wordpress (the 'category' and 'tag' value set in the backend). Could you please point me in the right direction?
I want to dynamically print the following - but only replace the `tags` and `category` part (not the tag/category itself):
<a href="/tags/my-tag">My Tag</a>
<a href="/category/my-category">My Category</a> | You really shouldn't need this, as you should be outputting the URLs via the API: `get_tag_link`, `get_category_link`, `get_term_link`.

Rewrite vs Redirect from ?p={ID}
WordPress does a 301 from ` to ` but I thought a URL rewrite was different from a redirect and therefore this wouldn't result in a 301.
Can anyone clarify? | A _rewrite_ enables ` to translate internally to the proper query vars to load the requested post. The shortlink does a 301 _redirect_ to the pretty URL because it should not be possible to access the same content from more than one URI. This is so a search engine won't index the same post under two URIs. | stackexchange-wordpress | {

bulk deleting empty items in the media library
I wrote a function, which should rename my attachments, based on the post title. Unfortunately this function created over 10.000 empty instances in my media-library, before I was able to stop it. The instances are all attached to a single post, which I could delete if it's necessary.
I'm really sorry to bother you with the ask for help, but I'm a bit scared to screw things up again. | Since I didn't expected an answer to this question I tried it with wp_delete_attachment();. I wrote this function on a random page of my site (since the site isn't live yet) and executed it from there.
$attac_kill_ids = range(1235, 22686); //fill an array with the post_ids from the empty instances
foreach( $attac_kill_ids as $kill_id ){
$kill_post = get_post( $kill_id );
if( $kill_post ) {
wp_delete_attachment( $kill_id, true );
echo '<br />killed #' . $kill_id;
}
else continue;
}
' _delete_ ' would be more precise, but ' _kill_ ' sounds more dangerous and keeps me concentrated thereby.

Possible to enqueue scripts and CSS to Multisite Network dashboard?
Is it possible to enqueue scripts and css **only** to the Network Admin Dashboard?
To edit the network admin menu, you have this hook: `network_admin_menu`, so I also tried `network_admin_enqueue_scripts`, but this didn't work.
Thanks! Roc. | You can use the global variable `$current_screen`. It has the property `is_network`, with a boolean value, that indicates if we are in `/wp-admin/network/` or not.

Filter post before *editing*

replace html entities in posts between pre tags
I run a wordpress blog with a syntax highlighter plugin (Crayon). The plugin highlights code between pre tags, example:
<pre class="lang:languageid" title="example">
some code
</pre>
Wordpress sometimes replaces characters suchs as `" & < >` with html entities which are shown in the code `"` `&` etc. I tried several plugins that should prevent this but they don't (always) work.
Is there an easy method to bulk edit old posts and search for entities between `pre` tags en replace them with the character? Or would it be easier to use a replace function on display and replace entities with their characters?
Any suggestions to prevent this in the future are welcome as well (perhaps extend/modify crayon?).
I usually write my blogs with Windows Live Writer but the behaviour also occurs when editing posts with the builtin editor. | Both answers are not the full solution, seems that if I combine them I am very close (just need to fix the replace part).

There is no way to split points, common best practice seems to be to combine both answer in your answer and accept that one. I hope that's ok for both?
The answer is then:
Use the Search RegEx plugin for wordpress and use a regex expression `|<pre.*>(.*)</pre|isU` to match html entities within pre tags. | stackexchange-wordpress | {

how to "not" display new posts with a specific category on the main page?
I've read this and this but I'm just a basic user.
I have a "technical" blog that more and more people visit.
I'm a freelance, and now, when someone hears about me, he/she wants to search for me, and my blog is #1 (before anything else).
The problem is that it was a personal blog, and now it becomes professionnal. So I would still like to post some articles, but when there are some specific tags (like "games", "family" and so on), I'd like them **not** to appear on the main page but only under the category filter (` ` would be ok, but _not_ `
How to do this? | There is even an example in the WordPress codex here for this: <
function exclude_category( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
$query->set( 'cat', '-3,-8' );
}
}
add_action( 'pre_get_posts', 'exclude_category' );
Just modify the category IDs (replace -3,-8 by your category IDs preceded by the minus sign) and put it in your functions.php or your plugin code.
The WordPress codex states the following:
> `query_posts()` is the easiest, but not preferred or most efficient, way to alter the default query. The preferred way is hooking into `pre_get_posts` and altering the main query.
This way you just alter the main query instead of throwing away the results of the first query and running a second. | stackexchange-wordpress | {

User registration on sub site
I have configured multi-site wordpress. I have some sub-sites as like **site1.mydomain.com** and **site2.mydomain.com**. Now i just want to enable the user registration on my sub-sites.
When a user clicks on register link in any sub-site (site1.mydomain.com or site2.mydomain.com) **it takes them to the main site** (mydomain.com) and register them as an administrater of another site. so he will be having another site as (site2.mydomain.com).

Theme Check: Could not find post_class
I've inherited a theme from a another developer that I've re-styled for a client. We're just about finished, but I thought I'd run it through the Theme-Check plug-in to see if there's any errors or problems.
Unfortunately there's a ton. I've gotten rid of most of them, but I have one Required left:
REQUIRED: Could not find post_class. See: post_class
I've read the WP page on post_class, but as a relative newcomer I still don't understand what it is, or why it should be _required_.
What should I do to fix this? | ## What it does
`post_class` adds classes to the posts on a post by post basis, usually adding them to some kind of post "wrapper". This allows for the targeting of posts with CSS rules according to various criteria-- category, tag, sticky, format, etc. That is, theme authors, plugin authors, and individual users can write CSS rules based on the classes added by `post_class` and get very fine grained control over layout.
## Why you want it
While I am not a canonical source, I am sure it is required according to the WordPress Theme guidelines to ensure a minimal functionality across themes. If you aren't submitting your theme to the WordPress repo you can do what you want. There are no WordPress Theme Police to track you down and spank you, but `post_class` and the related `body_class` are very useful and easy to implement. I see no reason not to use them. | stackexchange-wordpress | {

Should all references to a text domain be to my current theme?

RECOMMENDED: Text domain problems in loop.php. The twentyten text domain is being used!
The site has no plans for being translated, so what's the best thing to do in this situation? Replace every reference to `twentyten` to my theme's text domain, or just remove all references of a text domain at all?
The WordPress documentation is a little confusing :-/ | You can remove all the translation references if you don't plan on translating it. You can also leave it in place, it shouldn't hurt anything..
If you want to remove it, go through your theme files and find references to `__(' Your Text', 'Domain')` and just change it to the "Your Text" portion. (Sometimes, you may even see `_e('Your Text, 'Domain')`). | stackexchange-wordpress | {

Do I really need the div class entry?

Removing any and all inline styles from the_content()
For one of my current projects, I had to transfer blogposts from an old Wordpress site to my project.
Things went smoothly until I've seen that all the posts were copy pasted from Word, leaving this before pretty much every paragraph:

Minimum Word Count Before A Post Can Be Made Pending Review
I'm looking for a way to check that a post has a minimum word count before allowing it to be sent for review (added to the pending post status).
Below is the code I have:
if (current_user_can('contributor')) {
function minWord($content){
global $post;
$num = 150; //set this to the minimum number of words
$content = $post->post_content;
if (str_word_count($content) < $num)
wp_die( __('Error: your post is below the minimum word count.') );
}
add_action('draft_to_pending', 'minWord');
}
This appears to "work", in that it brings up an error message when the word count is indeed below 150. However, the post is still saved as a "pending". Is there any way to prevent the post from being made pending, but instead keep it saved as "draft".
Cheers
Peter | Those transition post hooks run after the post is saved. You will have to interrupt the process earlier. I would hook to `wp_insert_post_data`.
function minWord($data){
if (current_user_can('contributor')) {
$num = 150; //set this to the minimum number of words
if (str_word_count($data['post_content']) < $num) {
$data['post_status'] = 'draft';
}
}
return $data;
}
add_action('wp_insert_post_data','minWord');
Seems to work when I test it. Following your code, this only effects the "Contributor" role. It does not interrupt status changes for other roles. | stackexchange-wordpress | {

"sufficient permissions" error for admin after duplicating WP database to new install

How to add menù section to my WordPress template?
I am pretty new in WordPress blog and I am developing a blog with this template: <
As you can see at the top of the page there is a "menù" that only show the page in the site (at this moment: "Home" and "Pagina di esempio").

If, in the administrator dashboard I go to the menù section in the "Position of themes" square say me that: **"This theme has no support for menus but it is possible use the personalized menu widget to add every created menu in the sidebar"**
So I think that my template have no definied a true menù section on the top (but only a list for the static pages). Can I add a true section where add a true menu? How can I do?

Andrea | 1. You need to edit functions.php andding the following line
`<?php register_nav_menu( 'primary', 'Primary Menu' ); ?>`

Previously had been working fine but I forgot the password but when I go through the process of 'Lost your password' I am meant to get an email with new password but it never arrives in my hotmail (also checked the junk) I know these can sometimes take a while to come through but it has been a day now.. Any ideas I could try?
Thanks | Probably you dont have any mail server installed/enabled (like sendmail/qmail/postfix) in your local machine. You can still reset your admin password from database. The table "wp_users" stores the password in the "user_pass" field
You can just replace the value with a md5 hash value of your desired password for the admin user.
_Note: This is good for test/local environments and dont do so in Production server because it invalidates the effect of salt :)_ | stackexchange-wordpress | {

How to add a class and title attribute to the link generated by next/previous post
The following code
<?php previous_post('%', '<', 'no'); ?>
<?php next_post('%', '> ', 'no'); ?>
returns these links, as it should
<a href="post_address/"><</a>
<a href="post_address/">></a>
My question is about adding a class and title attribute so that the code returns
<a class="normalTip" title="Previous Project" href="post_address/"><</a>
<a class="normalTip" title="Next Project" href="post_address/">></a>
I am using the iWR Tooltip plugin and would like to use it on the links for the post navigation.
There is probably a simple solution by adding something to the function.php file, but I have not come up with the answer. Any ideas? | `previous_post` and `next_post` are deprecated. you should be using `previous_post_link` and `next_post_link`. That function applies the `{$adjacent}_post_link` filter. You can use that to get what you want. A very, very crude example:
function construct_np_attr_wpse_92086($matches) {
if ('prev' == $matches[1]) {
$np = 'Previous';
} else {
$np = 'Next';
}
$ret = 'rel="'.$matches[1].'" class="normalTip" ';
if (!empty($np)) {
$ret .= 'title="'.$np.' Project"';
}
return $ret;
}
function add_attr_to_np_links_wpse_92086($link) {
return preg_replace_callback('/rel="([^"]+)"/','construct_np_attr_wpse_92086',$link);
}
add_filter('next_post_link','add_attr_to_np_links_wpse_92086');

Collect Data from NEXT item while in loop
I am trying to get the value of a custom field. The trick? I'm in the loop, currently printing out 2 of 5 for this example. I would like to get some info from 3 of 5 (or even 1 of 5) while printing out info on 2 of 5. I hope that makes sense. Any help would be great! | As you posted no code and little in the way of exactly what criteria you are using, I can't really writ functioning code but inside your Loop try:
var_dump($posts[$wp_query->current_post -1]->post_title);
That is, `$posts[$wp_query->current_post -1]` is the previous post. You can change `-1` to plus or minus whatever value you want but the math cannot result is a figure below `0` or above your posts_per_page -1 (I think), as those don't exist. The query only gets posts on "this page". If you do need information from posts that appear on a previous or next page you will have to query for that information. | stackexchange-wordpress | {

Format Buddypress Date Picker Output
I've created a custom profile field for my BP users and I'm looking to show the value on the user's profile page. The code below does this...
<?php bp_profile_field_data( array('user_id'=>get_the_author_meta( 'ID' ),'field'=>'birthday')); ?>
...But it displays it as "1985-10-30 00:00:00".
How can I format this to display like this: "October, 30 1985" | I have no idea if BuddyPress has built in date functions but WordPress does and PHP does. This should do it:
$bpress_date = bp_profile_field_data( array('user_id'=>get_the_author_meta( 'ID' ),'field'=>'birthday'));
// $bpress_date = "1985-10-30 00:00:00"; // test
echo date('F, j, Y',strtotime($bpress_date));
PHP's `date` expects UNIXTIME. That is why the date string is passed through `strtotime`. It does not work without that step.
You probably want to consider using WordPress' `date_i18n`, however, which would look like:
echo date_i18n(get_option('date_format'),strtotime($bpress_date));
This gives you some ability to internationalize things as the date will displayed according to the blog's date format settings. | stackexchange-wordpress | {

Fetch all Posts where logged in user has commented

Thanks! | It should be simple since comments are stored with a user_id if they are created by a logged in user and if not then its set to false so all you need to do is select the post id from comments that are made by user_id bigger the zero, something like this:

How to not show post_thumbnail from specific category for not logged users

Why does this loop only work on the homepage?
I've been trying to figure this out all day now.
Consider the following code below:
<div class="slider">
<div class="slides"><?php
wp_reset_query();
if(have_posts()) :
while (have_posts()) :
the_post();
if(is_sticky()) : ?>
<div class="slide"><a rel="bookmark" href="<?php the_permalink() ?>"><?php echo the_post_thumbnail('full'); ?><h2><?php the_title(); ?></h2></a></div>
<?php endif;
endwhile;
else: ?>
<p>Sorry, no posts matched your criteria.</p>
<?php endif; ?>
<div class="left-arrow"></div>
<div class="right-arrow"></div>
</div>
</div>
The loop above doesn't work on the site's pages (e.g: page 2/3/4) or 404.php, but works perfectly fine on page 1 (the index.php).
Why is that and how do I fix this? | If you look at that code carefully, the only thing it ever prints are sticky posts:
if(is_sticky()) : ?>
<div class="slide"><a rel="bookmark" href="<?php the_permalink() ?>"><?php echo the_post_thumbnail('full'); ?><h2><?php the_title(); ?></h2></a></div>
<?php endif;
You stand a better chance of having sticky posts on page 1 of the index than on any page thereafter. 404 pages don't have posts at all, sticky or not. That is why they are 404 pages.
I think that is why the code **_appears_** not to work on some pages, but it isn't that the code is broken, just that the conditions for printing post data and not met. | stackexchange-wordpress | {

more tables created when create a new site
Can someone suggest me an idea on this?
I am using Wordpress MU. And as per my requirement every user who register on main site will have a sub-site for them. And it is working correctly.
I noticed that whenever a new site is created it is creating few tables in the database as like wp_2_post, wp_2_postmeta and so on. **Whenever a new site is created, it is creating about 9 new tables in my database**.
**If i have 1000 users in my site, then will it create about 9000 new tables in my database?**
I will be having lot more users with my site.
So, can someone tell me is this right? Can i have this much of tables in my database? Or can i do anything else to avoid this? **Is there any other way to avoid this.?** | Yes, this is the correct behavior, and no, there is nothing you can do about it in a multi-site setup. But that's usually not a problem; disk space is cheap.
Maybe you could run a workaround with a single-site installation and rewrite rules to map subdomains to URLs like `/author/post-name/`. But that sounds like a collsion magnet; so I wouldn't recommend it. | stackexchange-wordpress | {

Hiding or removing file extension displayed in HTML on attachment page
I’m doing up a photography theme in WP at the moment, and I’ve already got great help on this thread (thanks Milo!) for a previous question.
In that thread, I asked about displaying the file name of an uploaded file on the `attachment.php` page for that file. I’m now using the suggested answer, which uses this code to display the name: `<?php echo basename( wp_get_attachment_url( $post->ID ) ); ?>`
What I need to do, however, is to display this file without its extension: so, `filename`, instead of `filename.jpg`. Is there any easy tweak to this existing PHP snippet that could do this? If not, what would be a best-practice way of achieving this end result?
I should add that I’m far from a PHP expert, so take it easy on me... :)
Thanks. | You could use `substr()`
> Returns the portion of string specified by the start and length parameters.
in combination with `strrpos()`
> Find the numeric position of the last occurrence of needle in the haystack string.
**Example**
$name = basename( wp_get_attachment_url( $post->ID ) );
echo substr( $name, 0, strrpos( $name, '.' ) );

Translate Woosidebars plugin strings
I'm trying to translate Woosidebars strings in french using PoEdit but my french strings are never shown on the front-end. English strings are always displayed, even when I change the language (And I can see it works since other plugins strings are well translated).

If someone had the same issue it would be great to share a solution!
Regards | I've finally found why this strange thing was happening on my website.
It appears there was a conflict with the WPML String translation module which was already installed and configured to translate widget strings.
`fr_FR.po` file was never called because the WPML plugin was configured to use database translated strings and not `.po`/`.mo` files for widgets. | stackexchange-wordpress | {

echo 'term ID ' . $term->term_id . ', term name: ' . $term->name . ', description: ' . $term->description . '<br/>';
}
}

/*
Template Name: Foo
*/

Best practice to update the file header.php

The built-in editor works just as well as any other text editor. That goes for any of your theme files, not just `header.php`.
The benefit of using an external editor (like Notepad++ and using FileZilla to FTP your changes), is that you have the possibility of using 'syntax coloring'.
I highly recommend Notepad++, as it supports multiple document encodings (UTF-8, ANSI, etc) and many scripting languages (with their generally accepted syntax coloring), such as PHP, JavaScript and CSS, your most common languages when working with WordPress. | stackexchange-wordpress | {

woocommerce product categories in menu
I am using woocommerce plugin, and added some product categories in appearance->menu. I mentioned that if I logging off, the product categories is not showing at all... please help.
sorry for bad english. | I found the answer. The main problem is:

Woocommerce category name "my category" has ID: 13
And
Wordpress page "Logout" has ID: 13
So, in woocommerce where is function called "woocommerce_nav_menu_items" is checking pages like "Logout", "Change password", "View order", "Edit address" to avoid show if user is not logged in. And this function is checking if you are not logged in, unset all these pages which would be in menu.
And it's happened what my created category in woocommerce was with the same ID like created page "Logout".

If this will happen to you just delete created category and create a new one, because the system will assign another ID to your category.

put this:

where $ID_OF_PARENT_CATEGORY is a variable holding the ID of parent category, from which you want to show the children.
# Showing parent
That category WON'T show. To show it, you must do some greater hack (here I'll show you only thing that I can think right now), since there are no argument like `include`, so that you can just include it.
You can show categories that are PARENT and it's siblings, so, you will show children of PARENT's parent. That means that you will put in args 'show_option_none=Select category&show_count=1&orderby=name&echo=0&child_of='.$ID_OF_GRANDPARENT.'&exclude='.implode(',', ARRAY_OF_PARENTS_SIBLINGS)

Fatal error: Call to undefined function wp_get_current_user()
I have some strange error or may be I do not have the skills to tackle this issue. I am building a plugin for Multisite. When is use `is_admin()`, my plugin works fine but when I use `is_super_admin` it shows me this error `Fatal error: Call to undefined function wp_get_current_user()`.

unregister_widget( 'WP_Widget_Pages' );
unregister_widget( 'WP_Widget_Calendar' );

I saw this question but it's not helping me. | `wp_get_current_user()` is a pluggable function and not yet available when your plugin is _included_. You have to wait for the action `plugins_loaded`:

function wpse_92517_init()
{
if(!is_super_admin())
add_action('widgets_init','my_unregister_widget');
}
function my_unregister_widgets() {
unregister_widget( 'WP_Widget_Pages' );
unregister_widget( 'WP_Widget_Calendar' );
}
Or move the check into the widget function:
add_action( 'widgets_init', 'my_unregister_widget' );
function my_unregister_widgets()
{
if ( is_super_admin() )
return;
// not super admin

Wordpress pagination on custom script
I am using WP for my RealEstate project where all properties are pulled from a custom table (wp_listing) and displayed in a custom page template (page-realestate.php).
I know WordPress has built-in pagination methods to deal with paged content (pages, posts lists). I want to use that same pagination methods for the list of properties I am fetching from my custom DB table.
Is this possible? How?
[EDIT]
Code is something like:
echo '<ul>';
$properties = $listing->getProperties();
for($i = 0; $i < count($properties) ; $i++) {
echo '<li>' . $properties[$i]['address'] . '</li>';
}
echo '</ul>'; | It is unclear exactly which "built-in pagination methods" you are looking for. WordPress uses several.
If you are looking for the `next_posts_links` and `previous_posts_link` functionality, write your own function as those built-in functions depend upon the `$wp_query` global as you can see in the source. I doubt it is worth the time and effort to try to hack that to work with data from your custom table.
If you want pagination as you see at the bottom of the admin edit post screen, the built-in function `paginate_links` is generic. So long as you pass in the proper values you can paginate your own data without a problem. I have done it, and it works well, but you have to be very careful with all the parameters. Based on the information in your question, I don't think I can write the code you need. Plus, I am not even sure if that is what you are looking for. | stackexchange-wordpress | {

Create custom field key upon theme activation
Upon theme activation I want to create an 'URL' key for the custom fields. Like in !this screenshot.
I know who to run functions when a theme is activated, I don't know how to create this custom field key though. Any thoughts? I don't want to be using custom meta boxes. | Those values are populated from the unique keys in the `*_postmeta` table, excluding keys that begin with an underscore (`_`). If you want to pre-populate that key the add a value to the table under post ID `0`. There is no way to pre-populate those that I am aware of besides to add a dummy meta_key/value to the `*_postmeta` table.
`add_post_meta('0','URL','');` does not work, at least not when I try, so you need to write the SQL.
$wpdb->query("INSERT INTO {$wpdb->postmeta} (post_id,meta_key) values (0,'URL')");
That will create numerous entries in the database, however, unless you take further steps to avoid it.
**I strongly advise against this hack.**
Using a custom meta box is by far the cleaner solution, and I cannot guarantee that there are no negative consequences to adding a dummy key/value to `*_postmeta`. I highly recommend that you reconsider the custom meta box option. | stackexchange-wordpress | {

Show all terms in a custom taxonomy with all child terms wrapped in a ul
Is there a way that I can list all the terms within a custom taxonomy in an unordered list and wrap all child terms in another unordered list?
For example;
<ul class="menu">
<li><a href="#">Parent 1</a></li>
<li>
<a href="#">Parent 2</a>
<ul class="sub-menu">
<li><a href="#">Child of Parent 2</a></li>
<li><a href="#">Child of Parent 2</a></li>
<li><a href="#">Child of Parent 2</a></li>
</ul>
</li>
<li><a href="#">Parent 3</a></li>
</ul> | You can take a look at the Wordpress function `wp_list_categories()`. If you want to display all the terms within a given custom taxonomy you can for example use:
<?php
$args = array(
'taxonomy' => 'my_custom_taxonomy_slug',
'orderby' => 'name',
'hide_empty' => 0,
'title_li' => '',
'hierarchical' => 1,
'walker' => null,
);
?>
<ul class="menu">
<?php wp_list_categories( $args ); ?>
</ul>
If you need to adjust the html structure, you can use a _custom walker_ that extends either `Walker_Category` or `Walker`.

How to make all the posts commentable by default? Imputs in Settings/Discussions are not saved
I've modified my website quite a bit and now looks almost as I desire. I've set all the posts to be commentable in Settings/Discussions but it seems that this imput is not saved and new posts by authors are not commentable. Everytime, I need to "quick edit" the new post and mark the |_|Allow Comments field as selected |x|. This takes me a lot of time and I wonder if there's a way to have a function to make all the new posts as commentable as, just like I said, it seems not possible to choose it as option in Settings/Discussions.
Thanks! | A common method to keep all the posts open for comments, is to add this line into the file `functions.php` in the current theme directory :
add_filter('comments_open', '__return_true');

Remove post_tag from default post type, add custom taxonomy

Which file renders the "Edit Gallery" Settings page?

Gravity forms and wp_update_post

Does the textdomain have to be the theme's name?
Does a theme's text domain have to be the actual theme name?
If you develop WP themes, couldn't you just use the same name (perhaps your business name) for all the theme's you develop, making it easier to copy and paste code as you develop? (even though a find and replace is rather simple). | The text domain is a unique identifier, which makes sure WordPress can distinguish between all loaded translations so Using the basename of your plugin/theme is always a good choice because plugin/theme basename is always unique though it is not mandatory to have plugin/theme basename as text domain, you can use any unique identifier.
If you're translating a plugin or a theme, you'll need to use a text domain to denote all text belonging to that plugin/theme. This increases portability and plays better with already-existing WordPress tools.
In general, an application may use more than one large logical translatable module and a different MO file accordingly. A domain is a handle of each module, which has a different MO file so you should not use same text domain for different theme/plugin instead it should be unique for every plugin/theme.

Currently this function that uses `add_filter` and `the_content` function reference is not working for the Admin Menu Management Page.
I create custom menu sets and place them in sidebar's using widgets for easily management "quick links" to other pages and documents.
I've been using the following codex page to find function references: Function_Reference. | There doesn't seem to be a single filter _just_ for a menu item URL, but in `wp-includes/nav-menu-template.php` there are a few filters:

* `wp_nav_menu` \- the completed menu just before output | stackexchange-wordpress | {

Using _s theme, menu changes do not affect header menu

adding a text message beside the comment submit button
What is the cleanest way to display a text message beside the submit button like this in screen shot:
!example of what I am talking about
I am currently doing it by editing the file `wp-includes/comment-template` line `1577` (wordpress 3.5)

value="<?php echo esc_attr( $args['label_submit'] ); ?>" />
after:
<input name="submit" type="submit" id="<?php echo esc_attr( $args['id_submit'] ); ?>"
value="<?php echo esc_attr( $args['label_submit'] ); ?>" />

Using Schema with `the_excerpt`

Really simple query giving error in SQL syntax
I'm sure this is a simple oversight but I cannot seem to narrow it down:
global $wpdb;
$tablename = $wpdb->prefix . "icrm_folders";
$sql = $wpdb->prepare( "SELECT * FROM %s", $tablename );
//$sql results in SELECT * FROM 'wp_icrm_folders'
$result = $wpdb->get_results( $sql );
This seems to result in nothing! My debugger shows an error on $wpdb object under last_error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''wp_icrm_folders'' at line 1
Now I ran the query `SELECT * FROM 'wp_icrm_folders'` directly in phpmyadmin and that gives me an error because wp_icrm_folders is inside `'` the query executes fine if I remove the apostrophes or replace them with the grave accent/character.

How to use get_post_custom function on the blog page?
First, I have a static page for homepage and for blog page too. I created a custom box for pages to setup unique background image for the pages. My idea is working on all page templates, but on blog page something wrong.
**header.php is same on all page**
<head>
{...}
<?php $values = get_post_custom( $post->ID ); ?>
<style type="text/css">
body { background-image:url("<?php echo $values['background_image_meta'][0]; ?>"); }
</style>
{...}
</head> | The basic problem is that there is no variable `$post` in your `header.php`. That variable might exist in the **global** scope, but your code operates in a function scope of `load_template()` which was called by `get_header()`.
So you have four options:
1. Import the global variable into your function with the `global` keyword. global $post;
// make sure everything is set up as a post object
$post = get_post( $post );
$values = get_post_custom( $post->ID );
2. Use `get_queried_object_id()` to get the ID, similar to hepii110’s suggestion.
$values = get_post_custom( get_queried_object_id() );
3. Use `get_the_ID()`. This does almost the same as version 1.
$values = get_post_custom( get_the_ID() );
4. Call `get_post_custom()` without the post ID. It will try to find the correct ID automagically.

Running Wordpress from MySQL Cluster with HAPRoxy
I'm trying to install a wordpress installation where the DB will sit on a MySQL cluster (Galera/Percona XtraDB Cluster) and connected through HAProxy.
Everything outside of the Wordpress install seems to work fine. Using the mysql client to connect to the database with a username and password works just fine. The Wordpress install is on the same server as the HAProxy. That works fine from command line when I do this:
mysql -u wordpress -p<password> -h <haproxy ip> -D wordpress
However, from the install GUI page, it constantly takes me to the "DB connection failed" page.
Can anyone shed some light on where the issue might be? Here is what I'm attempting to use in the install from:
database name: wordpress
username: wordpress
password: <password>
database host: <ip of haproxy server>
table prefix: wp_
Thanks for any suggestions! | SELinux was contributing to the problem. The main issue was that an HTML page was attempting to talk to another port on the localhost. I would not have seen the problem if the HAProxy was running on a separate host.
The log was revealed in /var/log/messages, where I should have checked but did not considering I didn't expect it. Fail on my part. The log looked like this:
`setroubleshoot: SELinux is preventing the http daemon from connecting to network port 3306 For complete SELinux messages.`
SELinux should not have been running to begin with, so I simply disabled it:
`echo 0 > /selinux/enforce`
To maintain this state upon reboot, simply edit the SELINUX line in /etc/sysconfig/selinux to say `SELINUX=permissive` rather than `SELINUX=enforced`. This will log alerts but not stop any processes.
