Custom Wordpress Does Not Display Anything But Background in IE
I have a custom, well kinda custom wordpress in only one page of my site, the background only displays in Internet explorer, no body or content just background though in firefox it's fine as with other browsers. Reverted back to the original twenty ten and it shows in IE. I know the code is horrible but it was a shot at making a custom theme and it worked fine before. If I thought I could fix it myself I wouldn't ask the pros here. You guys have helped me a ton !!
Also, if you view the source, it shows content being there.
<
Sincerely Mark | In your initial style declaration that sets the background color:
background:#000D37;
You have an open HTML comment but no close. Close that and you should be fine. | stackexchange-wordpress | {

woocommerce and is_user_logged_in() if not redirect to homepage
I am currently using woocommerce and would like to redirect none logged in users to the home page, however i am having a little trouble determining where i should implements this
I have done research and determined that using the is_user_logged_in() i can see if the user is logged in.
I tryed implementing in the woocommerce/woocommerce-functions.php
// When default permalinks are enabled, redirect shop page to post type archive url
if (is_user_logged_in() && isset($_GET['page_id']) && $_GET['page_id'] > 0 && get_option( 'permalink_structure' )=="" && $_GET['page_id'] == woocommerce_get_page_id('shop') ) :
wp_safe_redirect( get_post_type_archive_link('product') );
exit;
endif;
but it still allows the page to be visible | You are going to want to insert your code at the top of the page templates for the Woo pages you would like the redirect to affect rather than the functions file. So for example if you want to redirect users when they try to access an individual product page you could put it at the top of the plugins->woocommerce->templates->single-product.php page.
When editing templates though I would recommend making a copy and placing it in your theme directory, so that when Woo updates it will not override any changes you made. So for the example I gave above (applied to my theme). I would copy single-product.php and place it in the themes->agency file and then make the changes to that file, there. Your theme will then always use that file before the one in the Woo template file. | stackexchange-wordpress | {

How to hide trackbacks on wp-admin/edit-comments.php
How to hide (or not to show, better said) trackbacks on wp-admin/edit-comments.php page?
I want to hide the comments with no email (also known as trackbacks) and comments with a specific email from the edit-comments.php page. | While this is not impossible, this is very likely to have ton of edge cases and backfire in some. In a nutshell comments are retrieved with comment query, which can be adjusted with something like this (if in admin and comment type not specified then only fetch normal comments):
add_action( 'pre_get_comments', 'exclude_pings' );
function exclude_pings( $comment_query ) {
if( ! is_admin() )
return;
if ( empty( $comment_query->query_vars['type'] ) )
$comment_query->query_vars['type'] = 'comment';
}
However the problem is "any comment query in admin" is too broad and there isn't much it can be narrowed down by.
Overall I would not recommend to mess with this.
PS excluding by author is not supported by native arguments and would be even more tricky with need to filter SQL. | stackexchange-wordpress | {

How to make wordpress use www.example.com/blog/wp-includes/ instead of www.example.com/wp-includes/?
I have WordPress at address < now I want it to be accessible as < without moving wordpress to root directory.

wp-config.php:

define('WP_CONTENT_URL', "

There are even includes like www.example.com/%post-name%/wp-includes/js/jquery/jquery.js?ver=1.7.2
I have fixed it through .htaccess:

Possible to use conditionals within add_feed() callback?
I'm using `add_feed()` to create some custom feeds but calls to `is_singular()`, `is_home()` etc... just don't seem to work within the callback. Is there a workaround for this?

function my_init() {
add_feed( 'new_feed', 'feed_output' );
}
function feed_output() {
if ( is_home() )
load_template( '/path/to/feed/home/template.php' );
else
load_template( '/path/to/feed/template.php' );
}

According to the codex article on add_feed it should be called with the `init` action, which runs before.

Add custom fields after post/page title
I am using the Headway theme, and I need to add custom field code to page & posttitles. This is what I need to be able to do.
example [edit:image has been deleted]
The red button will be added through a custom field. It needs to be shown inline with the title. I have worked out I can do this using the `headway_after_entry_title` hook, but I can't seem to get the code right to retrieve the custom fields. I got this far :
//Add custom field image after entry title
function title_btn() {
echo '<div class="title-btn">[custom field code to go here]</div>';
}
add_action('headway_after_entry_title', 'title_btn');
and the outcome should be:
<a href="xxx"><img src="xxx"></a>
where the xxx is the custom field url code
Hope anybody can help me out with this. | There's the `get_post_meta()` function to retrieve those data.

add_menu_page() with different name for first submenu item
The `add_menu_page` documentation says to pass the menu title as the second parameter:
add_menu_page('Page Title', 'Menu Title', ...);
When adding more pages later via `add_submenu_page`, the main page becomes the first entry in the submenu:

* * *
However, I want the first item in the list to have a different name (but still point to the same page), the way Wordpress itself does it:
!enter image description here
* * *
How could I accomplish that in my plugin? | You can make the 'slug' for the submenu page equal that of the top level page, and they'll point to the same place:

Remove Open Sans from Twenty Twelve theme
I´m creating a child theme for Twenty Twelve v1.0 and I want to remove the Open Sans font.
Open Sans is added in Twenty Twelve´s functions.php:
wp_enqueue_style( 'twentytwelve-fonts', add_query_arg( $query_args, "$protocol://fonts.googleapis.com/css" ), array(), null );
I´ve tried to deregister/dequeue the stylesheet in my childtheme´s functions.php (see examples below) but to no effect:
function example_scripts_styles() {
wp_deregister_style( 'twentytwelve-fonts' );
wp_dequeue_style( 'twentytwelve-fonts' );
}
add_action( 'wp_enqueue_scripts', 'example_scripts_styles' );
Any ideas how I can remove this file? Thanks! | Found the answer here:
> Script dequeuing calls should be added to the wp_print_scripts action hook(..). This is because scripts are typically enqueued on the wp_enqueue_script hook, which happens early in the wp_head process. The wp_print_scripts hook happens right before scripts are printed, and thus is latest in the process. (Otto)
Following the same logic we can use `wp_print_styles` to remove the Open Sans font:
function remove_open_sans() {
wp_dequeue_style( 'twentytwelve-fonts' );
}
add_action('wp_print_styles','remove_open_sans');

How to disable main query?

How to disable main query for home, category and search pages? | This is not trivial, because "home,category and search" are logically determined while main query churns through stuff. I am pretty sure I read this is possible, but that was in context of syndicating site that hadn't used posts/loop at all and scrapped it to do different stuff.
More typical approaches are:

Multiple multisite instances connecting to the same database
I like the idea of making developers connect their copies to the same database and just set `WP_HOME` and `WP_SITEURL` to configure the domain name as they like it. In this model, we don't need to keep migrating databases between servers, and the content will be kept in sync between developers. We also use this for staging, as each version has its own `wp-config.php` file.
If we try to make the same with multisite installs it won't work because it relies much more in the database values for domain names. So, what would be the best way of making multiple multisite development copies with different domains connect to the same database for development purposes like the non-multisite sites we're already dealing with? | Instead of changing WP_HOME etc, it would be best to enforce a single domain, e.g. local.example.com or shared.example.com and then use the HOSTS file to set that address to 127.0.0.1
This way there is no change to the URLs at all as it is unnecessary, and the shared DB content is consistent (this menu doesn't work on Alice' machine because Bob created it on his machine, and he uses a different domain name to Alice )
Also keep in mind your situation has the fatal flaw of sharing post content, but not post attachment files/uploads. | stackexchange-wordpress | {

What's the difference between wp_insert_user() and wp_create_user()
I know the former allows additional parameters, so you can more user info, but other then that, why do both exist?
The specific reason I want to know is that wp_insert_user() is happening REALLY slowly. Somewhere between 5 - 10 seconds. I don't remember having this problem in the past, when I was using create_user, so I'm wondering if there's a lot more happening behind the scenes with one as opposed to the other.
Thanks. | None. The whole source of `wp_create_user()` is:
function wp_create_user($username, $password, $email = '') {
$user_login = esc_sql( $username );
$user_email = esc_sql( $email );
$user_pass = $password;
$userdata = compact('user_login', 'user_email', 'user_pass');
return wp_insert_user($userdata);
}
It just calls _insert_ version almost immediately, basically a shorthand wrapper. As for why it exists - core works in mysterious ways and (short of hunting down developer by version control history and asking) there is rarely way to tell. :) | stackexchange-wordpress | {

Hierarchy of Subcategories on Permalink (bug?)
I found out something weird today.
The current permalink is set to `/%category%/%postname%/` but this happens (example):
I have a parent category `Food` and 4 subcategories `Burger`, `Pancake`, `Waffles`, and `Pizza`. As expected, the link should appear like this: `foo.com/food/burger/post-name` but it only works on 2 of my categories and looks like so:
foo.com/food/burger/post-name-1
foo.com/food/pancake/post-name-2
foo.com/food/post-name-3
foo.com/food/post-name-4
I'm refreshing the permalink settings but it doesn't seem to work.
I've even tried renaming Burger and Pancake to something else, both of them still look fine. But even if I rename Waffles and Pizza to Burger and Pancake, they still don't appear in the permalink.
Any quick solutions for this? Do I have to enter a custom taxonomy thingy? | When a post belongs to more than one category, regardless of their parent/child structure, WordPress will use the category with the lowest ID in the permalink. If that lower ID belongs to a child category, you'll see the parent/child structure in the permalink.
If you always want parent/child category appearing in the permalink, a simple solution would be to only assign the child category to the post. | stackexchange-wordpress | {

Were the language toggles removed from WP recently?
I need to change my weblogs language to "English".
I am refering to the article: < which allegedly was "Last modified: July 16, 2012".
I only looked for this option in v.3.4 forward and I cannot find it. It's also absent in v.3.5 beta 1. I initially installed and still use the German locale.

2). Could my webhoster be at fault somehow? They offered the "WP One-Click-Install" option, which I thought shouldn't hurt things - I guess I was wrong...

Force image crop size in media editor
I've searched high and low for this but think the answer I seek is being buried by the more common questions.

Help Understanding Template Hierarchy
I must be thick, but I could use some help grasping the way template files are chosen to be used. I noticed loop.php is no longer around, and looking at the file structure for twentytwelve there is now a 'page-templates' directory. As well as content-* files. We have index.php, page.php, content.php which one is used when? I know index.php is the "last resort" choice, however does content or page come first? And what is the difference between them? Thank you. | Template hierarchy consist of templates, but not every template file is necessarily in hierarchy.
Essentially hierarchy determines entry points (one of matching templates with pre-defined name structure), but from there template can further load additional arbitrary files.
`page-templates` directory holds custom templates for pages (`is_page()` branch in hierarchy). It's recent development that they can now reside in sub-folder.
`content-*.php` templates are called by Twenty Twelve like this from other templates: `get_template_part( 'content', get_post_format() );`. They are named arbitrarily and not part of template hierarchy - just a code organization choice that developers of this specific theme made. | stackexchange-wordpress | {

this is pulling out all post with the categoy 'news' which has cat id equal to 1.
depending on your needs there are two possible things you can do.
1 - if you simply want all posts with N categories displayed without any other customisations, you need to create a menu entry link which calls both of your categories i.e. which you can test in the browser:
2 - if you want something more complicated you will need to create a specific page and modify the loop; these might give you an idea: multiple categories < multiple cat with selection control <

Why do I get Fatal error: Call to undefined function get_most_recent_post_of_user()?
I am using WordPress 3.4.2. The codex doesn't say anything about this function being deprecated: < | get_most_recent_post_of_user() is for multisite installs to get the most recent post of the user from each blog.
Here is a comparable function you can use that will return the post object of the defined users most recent post.
function wpse_get_user_recent( $user ) {
global $wpdb;
$recent = $wpdb->get_row( $wpdb->prepare("SELECT ID, post_date_gmt FROM {$prefix}posts WHERE post_author = %d AND post_type = 'post' AND post_status = 'publish' ORDER BY post_date_gmt DESC LIMIT 1", (int)$user ), ARRAY_A);
if( ! isset( $recent['ID'] ) )
return new WP_Error( 'No post found for selected user' );
return get_post( $recent['ID'], 'ARRAY_A' );
}

$post = wpse_get_user_recent( 36 );

Force Plugin to English Translation
Here's my thing:
I'm using a plugin that has multilang capabilities. The point is that the language translation in my country lang is very bad and it makes more complex than simpler my work. :D. So is there a way to force a plugin to not to use multilanguage and be showed, at least, in English? | What's the plugin? Is it using custom translations in mo/po files? Is there an admin interface which allows you to set the plugin locale?
There is a generic filter which you might be able to add to the plugin code to set the language which might look something like the following (obviously set the language to what you want:
add_filter('locale', 'wpse_get_locale');
// returns the locale based on user preference
function wpse_get_locale($locale) {
// get_current_user_id uses wp_get_current_user which may not be available the first time(s) get_locale is called
if (function_exists('wp_get_current_user'))
$loc = get_user_meta(get_current_user_id(), 'user_lang', 'true');
return isset($loc) && $loc ? $loc : $locale;
}
However I wonder if it might not be easier to improve the translation of the plugin by editing the mo/po files or whatever they use for the string translation? | stackexchange-wordpress | {

how to place a link on the first post only using a plugin

Hook into the rendering of a WordPress Template
I have to use WordPress as some meta templating system and include some `JSP` snipptes which will be evaluated later with Tomcat after rendering the page statically. But naturally the `JSP` Code could not be interpreted by the php parser. This results in plain text strings mixed with the interpreted template parts.
**Is there any way to hook into the (pre) rendering of a WordPress Template?**
I need way get access the rendered template so i can strip out the `JSP`-Tags. Maybe wrapped between some unique tags or something else. But this ist not part of this question.
## Example
<?php get_header(); ?>
<render:jsp>
<%= request.getParameter("title") %>
</render:jsp>
<?php get_footer(); ?> | You can, but WP doesn't offer you the possibility to do it in a nice way, so you have to use output buffering.
Something like:
// before template is included
add_action('template_redirect', function(){
// you can do some checks here
// perhaps you need this only a certain page?
if(!is_home())
return;
// capture output from here on...
ob_start(function($html){
// this function runs after the capture ends,
// you can replace your tags here
$html = strtr($html, array(
'<render:jsp>' => '<!--',
'</render:jsp>' => '-->',
));
return $html;
});
});
The contents of the buffer are automatically sent by PHP to the output just before the script finishes execution. | stackexchange-wordpress | {

Displaying the most recently used tags

The only things that I found were the WP Recent Tags plugin which is a bit outdated and no tags are displayed when I use the widget.
I found the following posts:
> <
> <
But they don’t work for me either. | Sure, just feed your tag list to wp_generate_tag_cloud:
$found_tags = $final_tags = $id_records = array();
// get last 10 posts
$last_posts = get_posts('numberposts=10');
// gather tags
foreach($last_posts as $post)
$found_tags = array_merge($found_tags, wp_get_post_tags($post->ID));
// prepare final tags for the cloud
foreach($found_tags as $tag){
// ignore duplicates
if(in_array($tag->term_id, $id_records))
continue;
// track ids...
$id_records[] = $tag->term_id;
// generate links
$tag->link = get_tag_link($tag);
// keep it

How to get post meta value and post in one query?
When query a post, I need not only the post but also the post_meta. But seems the post query and meta query can not be done together.
With WP_Query, I first get the posts, then, I need to do `get_post_meta(get_the_ID(),'key',true)`
Is this the way WP works? Or, is there a way to query both in one hit? | ## When you do a query WordPress already gets the post_meta.
Even though you are calling `get_post_meta()` It is not performing another query. It is retrieving the value from the post meta cache.
Now if you don't need the post meta you can set a flag that will eliminate the additional MySql query. To do this you set `'update_post_meta_cache' => false` in your args. | stackexchange-wordpress | {

Post processing of uploaded file
When a file with the `.xml` extension has been uploaded on my blog (via the Add Media uploader) I would like to automatically replace some attributes.

I would like that Wordpress modifies it automatically in:
<content creator="bar"></content>
What hook should I use and how? | You can do this using the `wp_handle_upload` hook:
Create a function and add it to this hook so it runs last, it will be passed an array. The array contains the location of the newly uploaded file:

Use MarkItUp as editor and not the default
Does anyone know if it is possible to use this editor as my WordPress editor and not the default. If so, how? | Yes, It is possible ... there is a good article on DigWP \- which points out one warning that MarkDown is not reversible (ie articles written in Markdown get saved in Markdown so if you ever turn off MarkDown, then you're left with goo on your screen).
There is a MarkitUp plugin on the WordPress.org ... While the project has a warning about its age, I think you could find it still works.
Have a search on WordPress.org there are other markdown plugins

Allowed memory size exhausted. WordPress side solution
I'm getting a well known error from the question title. The problem is, website is running on a shared server and I don't have access to php.ini file.
I've set `php_value memory_limit' inside .htaccess to higher value.
I've set `WP_MEMORY_LIMIT` inside wp_config.php to higher value.
`phpinfo()` says that `max_execution_time` is set to 30 and `safe_mode` is off.
My question is, can I change something inside my WordPress installation to make my website work? I've read about `set_time_limit`. Can it help me somehow, or the only solution is to move onto another server? | You can simply create a text file and call it php.ini . Make sure the file has the text encoding "Unicode no BOM", as that will work best for both linux and windows. Use an FTP client to make a new file on the server and that will generate a file with the correct permissions and text encoding.
Put just this line in it:
memory_limit = 64M
_But that will not raise your memory allocation_ if the host doesn't allow individual php.ini files in accounts which override the server php.ini, which sounds like is the case, since they don't allow .htaccess to override the server. And it's doubtful they will change your php.ini file for you.
Usually bumping memory in wp-config.php is sufficient, and there's no need to edit .htaccess. Many hosts allow individual php.ini files. You're on a very restrictive host. I'd change hosts. | stackexchange-wordpress | {

Where does the gallery shortcode gets its attachments from?
I know that media are an attachment post type that are children to a post, but how are galleries stored in WordPress? | This completely depends on how your gallery shortcode looks like.
If you replaced it with something custom, then you'll have to take a look at the plugin (or the theme).
The default gallery shortcode gets it from a query:
$query_args = array(
'post_status' => 'inherit'
,'post_type' => 'attachment'
,'post_mime_type' => 'image'
,'order' => $order
,'orderby' => $orderby
);
Then it decides to add additional args for either `include` or `exclude`.
Here're the 3 scenarios that add the additional/non-shared arguments.
'include' => preg_replace( '/[^\D,]+/', '', $include )
'exclude' => preg_replace( '/[^\D,]+/', '', $include )

include <p> content within conditional statement?

echo do_shortcode('[nggallery id=1]');
} else {

?>
I'm wondering, is there a way to include page specific content in that? For example, if that code is used to show A's gallery, how can I include A's bio info within that statement(using `<p>`)? | You can do that via `echo`, just place it on a new line inside the if conditionals braces `{` and `}`
e.g.
if(this statement is true)
{ // <- do everything between here
/*
stuff that happens if the statement is true
*/
} // <-- and here
else
{
// stuff that happens if the statement is not true
}
So you could do this:

I mean they take a lot of database space and apparently have no use after the post has been published. | It all depends on your workflow. If you have no use for the post revisions and autosaves then disable them in wp-config and WordPress will clean them up on its own. You may also prefer to limit how many you keep at once.

Allow all file types for upload
I'm using Wordpress 3.4.2 for a private blog, i.e. one on which only I can post. Now, Wordpress prevents me from uploading certain file types (like C# source files). As far as I understand it, there's a white-list that defines what can be uploaded.
Is there a plugin that can extend - or better, even disable - this white-list?
All other answers tell me I should edit my theme but I'd rather have a plugin for that (so that I don't need to edit all my themes).
Also, I found this plugin but, again, it requires me to edit some file on my server (that's probably overwritten when the plugin is updated).

Website loading slowly - Advanced Custom Fields images
I'm currently using `get_field` with Advanced Custom Fields plugin (see here) to get a single image for search results.

Change post title during post saving process
My theme and Qtranslate plugin have a conflict and cause many issues on my website's post titles. I cannot trace what causes the issue and I thought that I could handle the title saving myself instead.
I would like to be able to change post title that wordpress uses when saving a post from backend.
How can I do that? | You can hook into `wp_insert_post_data` and change things.
<?php
add_filter('wp_insert_post_data', 'wpse67262_change_title');
function wpse67262_change_title($data)
{
$data['post_title'] = 'This will change the title';

Obviously you're going to have to some checks and stuff so you don't change every post title. That hook will also fire every time the post is saved (adding a new post, updating, trashing a post, etc) and for every post type. `$data` is an associative array with every column you'd find in the `{$wpdb->prefix}_posts` table as keys. So if you just wanted to changed posts:

add_filter('wp_insert_post_data', 'wpse67262_change_title');
function wpse67262_change_title($data)

Display all posts starting with given letter?

I was thinking about custom post types at first, but creating and maintaining 26 custom post types sounds like an overkill.
What will be the most efficient way of sorting posts like that? Database query, splitting loop with PHP? I am aiming for 1000s of posts (yes, it has to be Wordpress :)). | Don't use post types, use taxonomy terms!
On save, set the object terms in an A-Z taxonomy, using the first letter of the post title. Make sure to force upper or lowercase for consistency. Make sure to create terms for each letter of the alphabet, and a term for numbers and other non alphanumeric symbols.
This should be faster than querying the first letter of each post title, and it gives you a taxonomy you can do more stuff with, like tag clouds, or term lister widgets! It's also a much faster way of determining which letters have associated posts and how many, without forcing the database to manually count, and you can use standard WordPress term APIs out of the box to do more complex queries, like posts starting with vowels | stackexchange-wordpress | {

Two exact templates, sidebar showing in one but not the other
I'm using the Roots WP Theme and for some reason when copy pasting the page-custom.php to create a home page template. The new homepage template is showing the sidebar but not the original page-custom template even though the two template files are exactly the same at this moment.

'page-custom.php'
)
);

How to order custom post type by multiple custom fields?
How to display posts with 'Event' custom type ordered by 'Start_Hour' and then by 'Start_Minute'?
'Start_Hour' and 'Start_Minute' are numeric custom fields.
I tried this, but it doesn't work:
$args = array(
'post_type'=>'Events',
'orderby' => 'meta_value',
'meta_key' => 'Start_Hour Start_Minute',
'order' => 'ASC'
);
$loop = new WP_Query( $args ); | Thanks to Bainternet I found the solution:
function orderbyreplace($orderby) {
return str_replace('menu_order', 'mt1.meta_value, mt2.meta_value', $orderby);
}
and...
$args = array(
'post_type'=>'Events',
'orderby' => 'menu_order',
'order' => 'ASC',
'meta_query' => array(
array(
'key' => 'Start_Hour',
'value' => '',
'compare' => 'LIKE'
),
array(
'key' => 'Start_Minute',
'value' => '',
'compare' => 'LIKE'
)
)

Missing thumbnails
For all the pics I upload to Wordpress I get such a link to the pic:
src='
Anf ofcourse Wordpress does not find it.
But if I change to with the firebug:
src='
Wordpress displays the picture. Where I should look for the problem? Thanks. | Seems to me you use a WordPress theme which uses some kind of php library to resize images. You should really use WordPress default `add_image_size()` and `wp_get_attachment_image` but if you were the one who created the theme you would already know that.
There are 3 things you can do:
* find a new theme that is not **that** outdated
* dive into `mytheme/thumb.php` and find out whats going on and where it fails
* update the theme wherever it uses thumbnails and/or different image sizes with the above default WP functions | stackexchange-wordpress | {

local WAMP admin user has lost privileges
I have a Wordpress 3.4.1 installed on a local WAMP server.
I am in the process of upgrading it to a network, but I now realise my admin account has no admin privileges:
1. No access to the Updates page (update-core.php) - I receive "You do not have sufficient permissions to access this page."
2. No ability to install plugins.
3. No ability to edit users.
4. No ability to go to Tools > Network Setup - same error as above.
* The **wp_capabilities** of my user account is **a:1:{s:13:"administrator";b:1;}**
* The **wp_user_level** is **10**
What is wrong here?
**Update** \- I added another admin account using PHPMyAdmin following this tutorial, but I receive the same symptoms for this 2nd admin account. | I've just done a new install of a newly download zip file, and the installation process stops at:
This page is blank, and nothing progresses.
I now recall this happened on my previous installation also.
If I refresh this page, I receive a message: "Already Installed You appear to have already installed WordPress. To reinstall please clear your old database tables first."
I can elect to log in from here, and doing so presents me with the ability to install Plugins, which I can't do on my other installation. | stackexchange-wordpress | {

delete category name in the pages
I'm looking for a way so that I can delete category's name in the pages.
I tried to find something for category in index.php but I couldn't find anything.
Please help me to solve this problem.
Thanks in advance | _**What theme are you running?_**
Are you referring to **Pages** or **Posts** because they are two different **types** or rather, what we call **Post Types**.
* **Pages** are normally controlled via your `page.php` template file
* **Posts** are normally controlled via your `single.php` template file
Commonly you will find category and tag functions in your `single.php` file, but calls to such functions are not strictly limited to a `single.php` file. They can in fact be used in multiple theme files.
So for example,
* if you are viewing a **Single Post** , then look within `single.php`
* if you are viewing a **list of your Posts** , then look within `archive.php`
You will be looking for template tags such as,
<?php the_category(); ?>
or...
<?php the_tags(); ?> | stackexchange-wordpress | {

Nonce best practices: hidden input vs. wp_localize_script?
I noticed while looking at the HTML of an edit page that WordPress uses a lot of hidden input elements for storing nonces. Is there a significant advantage to using either this style of storing nonces for AJAX use or using those stored via the `wp_localize_script` style? | Depends, will the form work with AJAX turned off?
If so use an input and degrade gracefully.
Otherwise, define nonces used by JS using JS for consistency, and to prevent grabbing stuff from the DOM | stackexchange-wordpress | {

Using do_shortcode with variables?
Struggling to get the format right for the PHP in this do_shortcode embed using variables from Advanced Custom Fields plugin. I think I've tried every variation on ., ', and ". After reading every resource I could find I'm still no closer.
<?php
$address = get_field('cong_streetaddress');
$city = get_field('cong_city');
$province = get_field('cong_province');
$postalcode = get_field('cong_postalcode');
echo do_shortcode('[pw_map address="'" . $address . " . " . $city . " . " . $province . " . " . $postalcode . "'" width="100%" height="200px"]');
?>
Doing it with just one variable, like so `echo do_shortcode('[pw_map address="'. $postalcode . '" width="100%" height="200px"]');` works fine. | Your syntax is broken, the quote marks do not match. Try to separate data from the shortcode template, and use `sprintf()`:
$shortcode = sprintf(
'[pw_map address="%1$s %2$s %3$s %4$s" width="%5$s" height="200px"]',
$address,
$city,
$province,
$postalcode,
'100%'
);
echo do_shortcode( $shortcode );
That’s much easier to read, and it is harder to create syntax errors. :) | stackexchange-wordpress | {

XML-RPC and post_date
I'm trying to set the post_date via XML-RPC and keep getting an error saying the XML isn't formatted properly. The code goes something like:
$post = get_post( $post_id );
$response = $client->query(
'wp.editPost',
array(
0,
$user,
$pw,
array(
'post_date' => $post->post_date
)
)
);
I'm hitting the same issue with `wp.newPost`. I know the date should be formatted ISO8601 but I'm just having no luck getting it formatted right. | There are a couple of issues here. First of all, `wp.editPost` takes a fourth parameter before the content struct -> the ID of the post you're trying to edit (should be an integer).
Second, you're passing a string for the `post_date`, so the client automatically converts this to a `<string>` tag before sending it to the server ... unfortunately, the server expects a `<dateTime.iso8601>` tag.
You can fix this by parsing the string date and passing an instance of the `IXR_Date` class instead. The client will parse it properly and the server will react appropriately. I've tested the following scenario on my own server:
$date = new IXR_Date( strtotime( $post->post_date ) ); // Parse the date to an IXR_Date object.
$response = $client->query(
'wp.editPost',
array(
0,
$user,
$pwd,
$post_id,
array(
'post_date' => $date
)
)

how to use the slide show of Skylark in showcase?
I created a page and I set the template as _showcase_ and then I went to setting->reading and as a static page I choose my created page.

How to add text to comment form #content textarea?
I have a plugin that does validation on user submitted comments. When validation fails, I want to redirect them back to the comment form, and have their comment still appear in the comment box, so they don't have to type it again.

Two installs conflicting - Pages redirecting
I have two installs of wordpress on my server.
**Site 1.** mysite.com
**Site 2.** mysite.com/othersite
The first wordpress install is located in mysite.com/wordpress, but is viewable at mysite.com, and the second install located in mysite.com/othersite, and viewable at the same address. I have page slugs activated for both sites.
**Site 1.** works perfect. I can login to both admin panels and they work perfect. On **Site 2.** i can view the index page, but all other pages redirect as follows:
1. redirect to the 404 page of **Site 1.**
2. if a page has a similar name in both sites e.g. mysite.com/contact and mysite.com/othersite/contact, it will redirect to the page on **Site 1.**
My guess is that something in the wordpress core files uses redirection for slugs. But this is a stab in the dark, and i have no idea how to solve it.
Any help with this issue would be very much appreciated.
Thanks | You have to ignore the "otherside" in the htaccess file of your "root" blog.
