Removing the base "Author" or changing it to something else. is it possible?
Is it possible to remove the AUTHOR base?
Is it possible change it to postedBy so that the urls is site.com/postedBy/joe
And finally, is it possible to remove a custom taxonomy base from the url so that a url like site.com/people/joe can become site.com/joe | Use the plugin Edit Author Slug to change the base.

wp_nav_menu li item empty
I created an menu by admin panel > Appearence > Menu. I have just one menu page in **menu_lateral_1** .
Or the result is
<li id="menu-menu_lateral_1" class="menu"></li>
<li id="menu-item-212" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-212"><a href="my_website">my page</a></li>
With following code :
$args = array(
'menu' => 'menu_lateral_1',
'container' => '',
'items_wrap' => '<li id="%1$s" class="%2$s">%3$s</li>'
);
wp_nav_menu($args);
I don't understand where the first item comes ?! | Take a look at the Codex documentation. The `items_wrap` attribute is for wrapping the list elements as a whole - not each individual menu item:
> Whatever to wrap the items with an ul, and how to wrap them with
If you look at this line you'll see that it is using `sprintf` to replace three place-holders in the provided `items_wrap`. The first being an ID, the second a class, and lastly the items.
Try:
wp_nav_menu( array(
'menu' => 'menu_lateral_1',
'items_wrap' => '<ul id=\"%1$s\" class=\"%2$s\">%3$s</ul>'
) ); ?>
This should give:
<ul id="menu-menu_lateral_1" class="menu">
<li id="menu-item-212" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-212"><a href="my_website">my page</a></li>

Can I use wordpress comments system to build a user review system within my website?
I am creating a part of my site where a user can enter a comment (review) and rate my web application. When a user enters a comment and rates my site out of 5, their comment will be available to the entire site (after approval).
I am not sure whether to go about this by making a database table for this and manually setting up user input fields into my custom DB table, or trying to use a wordpress plugin, or try and leverage the wordpress comment system in a mixture of both.
Can anyone provide an idea of the best way to go about doing this? | You can use comments and store individual ratings using `add_comment_meta()`.
You would also probably want to store the rating average using `add_post_meta()`, since it's rather expensive to calculate it on the fly. Each time a rating is added or removed, you will have to update this average.
I don't know if there are any plugins that do this already; haven't searched. | stackexchange-wordpress | {

Sort posts by most recently modified
Is there a way to list posts in the order in which they were modified?
For example;
A user posts 5 posts (#1 being the oldest and #5 being the newest), by default they would be listed with #5 being at the top, but say the user edited post #3 at a later date, is it possible to then list post #3 above #5 without manually changing the page attributes?
This is a secondary query by the way, using get_posts | If you use `WP_Query` you can set the `orderby` to `modified` and then the order to `DESC` and you'll be good to go. If it's not a custom query, you can just use the `set()` method on the default `$wp_query` global to do the same. Since `get_posts()` is just a wrapper for `WP_Query`, you can set the `orderby` parameter there if everything else is working and not change anything else. | stackexchange-wordpress | {

is there an update_post_meta action
Are there any actions I can hook into for update_post_meta()? I don't see anything obvious in the source. Woocommerce lets you change the featured status of items via ajax from the edit screen. I am using a transient to store the featured items in lieu of querying them every time and I'm deleting that transient on the save_post hook, but it isn't getting fired because of the ajax function that directly updates the post meta. Worst case I can unhook woo's action and recreate it myself with the delete transient call, but I'm wondering if there is another hook i could use. | (See codex) `update_post_meta()` calls
update_metadata('post', $post_id, $meta_key, $meta_value, $prev_value);
This function is here. And there are plenty of hooks/filters:
(In example of 'post', `$meta_type='post'`)
## Before metadata is updated:
`update_{$meta_type}_metadata` (here) **Filter**
- _If this returns anything other than 'null', the metadata won't save_
`update_{$meta_type}_meta` (here) **Action**
## After metadata is updated:
`updated_{$meta_type}_meta` (here) **Action**
`updated_post_meta` (here) **Action**
- _For posts only_
All the actions take `($meta_id, $object_id, $meta_key, $meta_value)` as arguments. The filter filters a `$check` and takes the above as additional arguments. | stackexchange-wordpress | {

Logout redirects to /forums/
A while back I installed a plugin which, upon logout, re-directed users to `/forums/`.
Unfortunately, I have no idea which plugin that was and whether or not it's still active/installed.
What code/db settings can I look for to remove the offending code?
Thanks in advance, | I discovered the Hikari Hooks Troubleshooter ( this weekend to find what plugins were loading my header with competing open graph metadata.
Enable it, and visit the frontend. There will be a modal dialog over your site which should list the hooks into wp_logout. One of these will be the offending plugin.
If you're still using the other parts of the plugin and there are no settings to turn that feature off, you should be able to remove it by adding `remove_action('wp_logout', $plugin_function)` to your theme's functions.php.

PHP if Condition not working

<?php if (!is_page('about-us') || !is_page('news-articles')) {wp_head();}?>
It seems to work great when I only use the command for one of the pages, but using an operator seems to mess things up. In some cases the pages load correctly, but the desired results are not happening. I've also double-checked to make sure that I'm referencing the pages correctly, and I'm confident that I am. | You should be using the "AND" operator, not "OR"

How to display a certain template element only for posts published within certain time range?

Wordpress add_rewrite_rules for custom URLs ending in .html

Wordpress category loop offset possible?
I have been on this for a while now and haven't really come across a solution to filter the posts on a category page using a sort of offset in php.
There are plugin for posts and pages but I am trying to achieve this with pure php and specifically for a category page.
Scenario example: A blog with 7 posts, setting the offset to say 3 would begin the loop on the category page to only show (Post4, Post5, Post6, Post7) and NOT (Post1, Post2, Post3).
I am wondering if this would be possible at all and be dynamic enough to apply to all categories without the need to specifically identify which posts to exclude via id numbers. | The 'offset' parameter does what you want. I've written this hack, it should help you...
<?php
//The third parameter corresponds to action priority,
//set it to change the order of execution in case of a conflict

function the_modified_loop($query){
//Remove 'is_admin' if you want the code to run for the backend category archive page
if(!is_admin() && $query->is_category()){
$query->set('offset', 3);
}

How to order results by date and meta key?
I'm using wp-postratings to rate posts which stores the rating as a custom meta value `ratings_score`. It gives you the option to use `r_sortby` to order the loop by highest rated but I want to give it a trending feel by dividing the $ratings_score" by how old the post is in days. So something like this..
$ratings_score = get_post_meta($post->ID,'ratings_score',true);
orderby = $ratings_score / days ago
How can I accomplish this? | You could do this by sorting on a calculated factor. Dividing the rating by the days gives a good starting point:
rating/days = factor (e.g. 15/6 = 2.5 or 11/3 = 3.6)
You can balance this to your needs by multiplicate the variables (rating and day) with any factor you like.
There are to ways to implement such a factor:
1. use wp-crons to hourly refresh the factor for each post and save the value as postmeta. So you can easily use a WP_Query and sort the posts by the meta_value_num.
2. calculate the factor directly in your post-loop | stackexchange-wordpress | {

making images scalable for responsive designs
Working on first responsive website template; layout is part fluid, with fixed sidebars, using media queries. I want to have some of my images be scalable. Per this article < it should be very simple, at least for manually loaded images. Add this to stylesheet:
img{max-width: 100%;}
img{ -ms-interpolation-mode: bicubic; }

How to handle shortcodes when using the JSON API
I'm wrangling a little logic problem:

For example:
JSON result->template->DOM injection->trigger hijack for gallery/slideshow/whatever the shortcode is?
The above method feels a bit dirty as I'd have to either keep firing a parser to process the shortcodes or else I'd have to use JQuery.live (seriously dirty).
Can anyone think of a more elegant way of doing this? | You can add your own AJAX API for `do_shortcode`. Add this to a suitable location (i.e. `functions.php` or a plugin):
add_action('wp_ajax_doshortcode', 'ajax_doshortcode');
function doshortcode() {
echo do_shortcode($_POST['text']);
die(); // this is required to return a proper result
}
And this to your Javascript:
$.ajax({
url : ajaxurl,
data : { action : 'doshortcode', text : <text> },
type : 'POST',
error : function(req, stat, err) {...},
success : function(data, stat, req) {...}
});
`ajaxurl` is defined on admin pages; see here for instructions for viewer-side applications.
Alternatively, you can set up such actions for all API functions you need, wrapping the original calls with `do_shortcode`. | stackexchange-wordpress | {

Current theme broken - after server and domain migration

get_term_children doesn't return an array of children terms

print_r( $children );

Security updates to 3.3.2
I know all security updates are important but given that how important on a scale from 1 to 10 is it to upgrade from 3.1.3 to 3.3.2.
I have some sites that need to be upgraded but the host has me locked down in an older version of php that limits me to 3.1.3.
I am currently running version 5.2.3 of php.
Thanks, Bart | Since WP 3.1.3 has come out, we've released:

* 3.2
* 3.2.1 - **security update**
* 3.3
* 3.3.1 - **security update**
* 3.3.2 - **security update**
On a scale of 1-10, skipping a single security update is about a 3 (bad, but not catastrophic). Skipping _4_ security updates, though, would be closer to an 8-9 ...
You should seriously consider moving to a new host if they're locking you on PHP 5.2.3. Even PHP 5.2.4 included several security updates, and the 5.2.X branch maxed out at 5.2.14. The current stable for PHP is 5.4 (thought 5.3.9 is still pretty solid). | stackexchange-wordpress | {

How to check user role?

$capabilities = $user->{$wpdb->prefix . 'capabilities'};
if ( !isset( $wp_roles ) ) {

if ( array_key_exists( $role, $capabilities ) )

can the_excerpt function also get images?

Does anyone know if there is a Wordpress function to get the timeout value of a saved transient? I am using a transient with a 5 minute timeout to cache data from a web API call locally. Between transient timeouts I load the data locally from the transient acting as a cache and secondary API throttle. What I would like to do is read and display the timeout value of the currently saved transient data so the user knows how long they need to wait before the next data refresh. The value is stored in the 'wp_options' table as '_transient_timeout_transient-name', so I assume I could use the global $wpdb object and just do a SQL query, but I wanted to make sure there wasn't a more elegant way. | So, after one minute of more thinking, there is an easy solution, although i did not try it myself:
$transient = '_transient_timeout_' . $_your_transient_name;
$transient_timeout = get_option ( $transient );
you should be ready to go with this.
Another Way throught the database would be:
$transient = '_transient_timeout_' . $_your_transient_name;
global $wpdb;
$query = 'SELECT option_value FROM ' . $wpdb->prefix . 'options WHERE option_name = ' . $transient;
$transient_timeout = $wpdb->get_var( $wpdb->prepare( $query ) );
the returned value is a timestamp, but i'm sure you know how to handle it from here. | stackexchange-wordpress | {

Custom post type and URL
Is it possible to remove alias from custom post type? Let me tell a bit more. For instance, I've created a post type, name "Book". So URL will be `domain.com/book/post-title` or `domain.com/?post_type=book&p=528.` I want the URL as `domain.com/post-title.`
Is it possible? | In short - you cannot, or at least _should not_.
`www.domain.com/post-title` is interpreted as post (if your structure is `%postname%`) and/or a page - and WordPress is set to deal with them as such, including any conflicts.
You can do the following:
add_action('init','wpse0845_add_rule');
function wpse0845_add_rule(){
add_rewrite_rule("([^/]+)/?",'index.php?book=$matches[1]','top');
}
(and then flush rewrite rules, _once_ ).
However, you'll notice that now your pages (and depending on your structure, posts too) give a 404. | stackexchange-wordpress | {

Manipulate Output of wp_list_something: select menu instead of li's
I'm working on a responsive webdesign where my navigation should swap into a select-menu when resizing the window in smaller sizes.
Is it somehow possible to add another param to functions like `wp_list_categories()` or `wp_list_pages()` so that it outputs `<option>item</option>` instead of `<li>item</li>`?
So what I wanna do is use `wp_list_pages()` and `wp_list_categories()` to ouput its default stuff in order to have a normal menu. However I also want to ouput the same pages and categories in a second `<select><option>…` navigation that is hidden by default but shown when a media-query is triggerd. Any idea how to dynamically produce this second menu?
Thank you in advance! | you can easily do this the same way as `wp_list_pages()`, using `wp_dropdown_pages()`. the args needed to retrieve the pages are the same. for the categories, use `wp_dropdown_categories()` | stackexchange-wordpress | {

Why does this WPDB code throw an empty WPDB error?
I'm writing a feed reader plugin for wordpress. I'm seeing a DB error that I can't figure out. First I create a table called user_entries. Then I put a sample entry into that table. When I try to delete an entry, I get a very strange error in my debug log. There are no foreign keys yet, no indices on the db, etc.

> WHERE owner_uid = 2 AND feed_id = 2; made by do_action, call_user_func_array, wprss_unsubscribe_feed, WprssFeeds->remove
So what is the error? It's just blank in there. This doesn't look like complicated SQL and it works fine in the phpmyadmin query window. I'm not sure what to do for a next step now, and I'd like folks to be able to unsubscribe from a feed! | The code you've linked to above:
//$sql set to raw SQL statement
$sql = $wpdb->prepare($sql,$feed_id);
if($wpdb->query($sql)){
$resp->uf_error = $wpdb->print_error();
}
So if there _isn't_ , an error you try displaying the 'error' with `$wpdb->print_error()`. Also`$wpdb->print_error()` doesn't **return** an error, it **prints** it.
It's (probably) the printing of that non-error that is causing an error in your second database query, the one for which an error is logged.
**Side note:** take a look at the `wpdb` class. There are methods in there that handle INSERT/UPDATE queries so you don't have to do them manually. | stackexchange-wordpress | {

Why is $wpdb->get_results failing on certain tables but not others (which have data)?
I'm trying to pull some custom data from a Cart66 table.
My code works whenever I pull results from standard WP table in (my array is populated and the print_r shows that data), but not with any Cart66 tables (it prints an empty array).
I am absolutely certain that I've got data in these tables (I've rechecked that I'm using the correct table names about 1,000,000 times). I've tried two Cart66 tables which have data in them.
The codex says the get_results class should work with any table, not just standard tables. I thought it might be the underscore that was causing trouble, but underscores are supposed to be fine, and indeed, standard WP tables with underscores work fine.
$rawproducts = $wpdb->get_results( "SELECT * FROM $wpdb->cart66_products" );
print_r($rawproducts);
This is maddening! Any ideas?
Thanks! | you do not have to specify the $wpdb again in your query, but be sure that your table uses the prefix, if it has one. if it doesn't, skip the part with the prefix. also, you should always prepare a manually added query first. this should do it:

Highlight menu item when on a custom post type?
I'm currently using this code to display a menu of pages. I'm using CSS to target the class `current_page_item` which works fine until you're on a page with a custom post type.

'walker' => '' ); ?>
<ul><div class="menu-button"><?php wp_list_pages( $args, 'sort_column=menu_order' ); ?></div></ul> | If this is for a one-off site, I would suggest doing this with CSS. Philosophically, adding the `current_page_item` class to a menu item when that's not true feels a bit wrong too.
As long as you're using the `body_class()` function on your `<body>` element in the theme, there should be a class called `single-{event}` where "{event}" is the id of the post type. Hence, add the selector `.single-{event} .page-item-{ID}` where "{ID}" is the page ID of the events page (you'll see that as the class on the menu item as well). | stackexchange-wordpress | {

How to update Post Meta values through the comment system

Keep formatting for tables copied from MS Word?
I've found that copying and pasting tables from MS Word was closest to easiest when it comes to making tables; rather than formatting a table from scratch in a WYSIWYG editor.
The one shortfall I've found is that the "center" formatting does not copy over. It LOOKS like it does but the formatting is not actually applied. you have to go through each cell and center it.
Just wondering if anyone has a clue on how the WP editor handles MS Word and maybe if there's a fix? | I actually have a pretty awesome way to get the HTML output of the Microsoft Word table formatting.

Allow users to register as a higher role than default with code
By default all new registrants for my site are assigned the role "contributor" and then I make them request an upgrade to an "author" account through a form.

What I'd like to do instead is send them a link to a registration page that signs them up under the "author" role.

Require file in functions from theme directory using PHP
I am trying to dynamically get the facebook php sdk from my current themes folder.
I am writing this in my functions.php, but all my attempts break the site.
See my attempts below...
require template_url('/') . 'facebook-php-sdk-6c82b3f/src/facebook.php';
require get_bloginfo('template_url') . 'facebook-php-sdk-6c82b3f/src/facebook.php';
Can any one help me understand why this does not work?

Changing the permlink and SEO
I have a doubt on changing my permlink structure for the second time. What happened was I have moved my old website to the wordpress blog by copying all the posts.
After the migration, i have set the 301 redirect to the new url of wordpress and now it is updated in the google. After that I found the permlink is not good I am changing the structure to shorter url.
I found the old urls are correctly redirected to the new one i think it is handled by the wordpress. Will it be a 301 redirect by the wordpress?
Please help me. | You can check the status of the redirect using any number of developer tools (chrome can do this by default). I believe the default redirect that wordpress does when the post title is changed is a 301, but I could be mistaken. If you need finer control (or would like regex support), the Redirection plugin is a great option, and it supports 301, 302, 307, and 404 codes out of the box. | stackexchange-wordpress | {

CSS classes for theme
Does anybody know predefined (suggested by WP) CSS classes which should I use in my theme?
I have seen somewhere in Internet a list of all CSS classes, which are used in WP theme, but can't find it.

The Theme Review Guidelines include the following, WordPress-generated CSS classes:
* Alignment Classes:
* .aligncenter
* .alignleft
* .alignright
* Caption Related Classes:
* .wp-caption
* .wp-caption-text
* .gallery-caption
* Post Classes:
* .sticky
* Comment Classes:
* .bypostauthor

Migrate comments to Disqus
Is there a way to migrate all comments on my blog over to Disqus somehow? Thinking about using Disqus rather than the regular WordPress comments, but I don't want to lose the comments that are already written. | !Disqus export comments

When I re-save a post with [code] sections, the entities are double-escaped (> becomes > etc)
I've a hard time googling for this issue. On my blog, whenever I update an existing page, code sections are doubly escaped. I.e., on a recent page I have
find /V "QWERTYUIOPPO" < calc.exe:yourads.txt
and after a recent edit it has become:
find /V "QWERTYUIOPPO" < calc.exe:yourads.txt
When I save it once more, it will escape the entities once more:
find /V &quot;QWERTYUIOPPO&quot; &lt; calc.exe:yourads.txt
Etc. Needless to say this is nasty. For pages containing a lot of code this is a real bummer. Until now I just did some search and replace actions, but this can't stay forever. Does anybody recognize this issue?
Here's an example page that illustrates this issue. Also in the screenshot for future reference (as I sure hope to solve the issue on my pages sometime soon).
!enter image description here | I face this issue quite often on my own site where I publish code tutorials. Unfortunately, there isn't a good solution. Instead, I recommend this workflow:
* Use the WYSIWYG editor to build your article content leaving placeholders for your code snippets.
* Switch to the HTML editor to add your code snippets

Should I remove transients from the wp_options table?
I have been doing some cleaning up in the database of one of my WordPress installs, and I noticed that the `wp_options` table was about 2.1mb, and had 1200 rows. I've gotten it down to around 800 rows, and 1.2mb. However, there are a bunch of transients.
Should I remove these? I know they don't autoload, so it probably isn't causing strain on the database.
Most of the transients have formatting like the following:
_site_transient_browser_03df11ec4fda7630a5...
_site_transient_browser_065e09a1287aadfb4d...
_site_transient_timeout_browser_03df11ec4f...

_transient_feed_mod_e6460a14e5784b3ee64f91...
_transient_timeout_feed_1a5f760f2e2b48827d...
So, is it worth taking the time to remove these?
Thanks for reading! Any thoughts are appreciated. | This is not an amount that is likely to cause performance issues. However if you are concerned about leftover transients it is worth looking into if any code you are using is consistently "leaking" them (creating transients that are never removed).

Overide a function that is inside a plugin
I would like to change the behavior of one function in a plugin. Instead of rewriting the file and having to deal with updates I would prefer a solution that works similar to the way add_filter works for the wordpress core. Is this possible using either php or wordpress? | If there are hooks in the function, this is possible, if not, there may be pluggable functions, where you can replace their function with your own custom function. I have not seen pluggables in plugins frequently, but with most of the more popular plugins, you do see actions and filters.
You may be able to interact with the plugin by changing the behavior of the functions which it calls to your desired effect. This can be tricky, and often results in hacky solutions, but it's better than nothing.
If there is not a way to interact with the plugin, then you can fork the plugin's code. Naturally, this is the least desirable, but it may be your only option. | stackexchange-wordpress | {

How to get Post ID with the Add Filter Function
I'm writing a plugin and am trying to figure out how to add data to the end of a post based on some Custom Meta Information.
So i've done this so far:
add_filter('the_content', 'AppendMeta');
And here is the "AppendMeta" function
AppendMeta($content) {
echo $content; // Echo out post content
$PersonName = get_post_meta($post->ID, 'PersonName', true);
echo 'Person: ' . $PersonName;
}
That code works if I replace $post->ID with the id of the post, but I need it to work based on the post the user is currently navigating. How would I pass the post id in as a parameter? $post->ID doesn't work in this scenario and I can't find out why. | Nevermind, found out I can use `get_the_ID();`.
This function will return the post id inside the `the_content` filter. The function simply declares the global `$post` object and returns its ID.
add_filter('the_content', 'wpse51205_content')
wpse51205_content($content) {
echo $content; // Echo out post content
$PersonName = get_post_meta(get_the_ID(), 'PersonName', true);
echo 'Person: ' . $PersonName;
}
If you don't want to use `get_the_ID()`, you simply need to declare the `$post` object global before using it:
add_filter('the_content', 'wpse51205_content')
wpse51205_content($content) {
global $post;
echo $content; // Echo out post content
$PersonName = get_post_meta($post->ID), 'PersonName', true);

Retrieving multiple values to the Post Meta (using an array)
I'm having a problem retrieving post_meta values that I have stored in an array. I use this for storing the array:
add_action( 'comment_post', 'add_food', 1 );
function add_food(){
global $post;
$testvalues = array('bread', 'cake');
update_post_meta($post->ID, 'food', $testvalues);
}
and this for retrieving it:
add_filter('the_content', 'print_food');
function print_food($content){
global $post;
$custom_fields = get_post_custom($post->ID);
$food_field = $custom_fields['food'];
$content .= $food_field[0];
return $content;
}
however, this is added to the content of my page:
a:2:{i:0;s:5:"bread";i:1;s:4:"cake";}
The technique works fine for the comment_meta. What am I doing wrong here? | Aha! I think I found your answer. Two facts:
* The description of the $meta_value argument on add_post_meta() functions's codex page notes:
> An array will be serialized into a string.
* The $single argument's description on the get_post_meta() function's codex page notes:
> If set to true then the function will return a single result, as a string. If false, or not set, then the function returns an array of the custom fields. This is not intuitive. For example, **if you fetch a serialized array with this method you want $single to be true to actually get an unserialized array back**. If you pass in false, or leave it out, you will have an array of one, and the value at index 0 will be the serialized string. (emphasis added)
Therefore, this [untested] snippet should get you your food array as an array rather than a serialized string.

# Second test

$test2 = get_page($page->ID);

$options = get_option('test_theme');
but I don't understand what that is returning. it calls this right before the form, presumably to loop through the options? the data is actually getting saved, it's just not being represented when the page is refreshed. | This sets $options to the value of test_theme in the database, you can go to phpmyadmin and the wp database and the wp_options (if wp is your prefix) and do a search on option_id row and you'll find it there.

Whole bunch of errors on WP website - media upload, edit slugs, edit screen not working
I am having a problem which I didn't meet before. I took a client website for just a small bunch of modifications, so I wasn't there when WordPress was installed or when the theme was developed.
But when I enter the admin area, I can not upload media, I can not edit slugs, and on top of all, the "edit" screen for pages and posts is not working: I can't see the text I am typing, I can't see the format buttons, I can't use the visual/html buttons (please see attached). The website in question uses Genesis framework along with a Genesis theme child. It has a bunch of plugins installed. Now I am asking you, in your experience, what could cause these problems?
\- WordPress was installed wrong
\- A plugin is causing the problems
\- It has something to do with Genesis
\- ...?

Can't get CSS Into the Head via add_action
I'm trying to add some CSS to the head part of the CSS but I can't get it to work (I want to add it to the head before the Theme CSS so the plugin user can easily over-ride plugins default CSS without !important over-rides). Here is what I tried:
<?php
add_action('wp_head', 'addCSS');
function addCSS() {
wp_register_style( 'prefix-style', plugins_url('AddToCartStyles.css', __FILE__) );
wp_enqueue_style( 'prefix-style' );
}
?>
EDIT: Maybe the way I worded this was confusing. I Don't want to include the CSS in the plugin Admin Page, I want to include the CSS in the regular theme pages (e.g. the pages the end user will actually see). | You don't call enqueue or register functions hooking into the `wp_head` hook. At that hook its too late to add more, I guess, unless you play with priority parameter.
Use the init hook to call `wp_enqueue_*` & `wp_register_*` functions.
Do it like this:
<?php
add_action('wp_enqueue_scripts', 'addCSS');
function addCSS() {
wp_register_style( 'prefix-style', plugins_url('AddToCartStyles.css', __FILE__) );
wp_enqueue_style( 'prefix-style' );
}

Add a Save Button to Custom Meta Box
> **Possible Duplicate:**
> Adding submit or update button to custom metabox?
I added a Meta Box Like So:
add_action('add_meta_boxes', function() {
add_meta_box('CNMeta', 'Custom MetaBox', 'CNCustomMeta', 'post');
});
I also added a thing that saves all of the meta information like this:
add_action('save_post', function($id) {
if(isset($_POST['CNPrice']) ) {
update_post_meta( $id, 'CNDetails', strip_tags($_POST['CNDetails']) );
}
});
So they can save it by updating the post, it would be nice if I could add a submit button at the bottom of the meta box that also updates the post (and doesn't popup a warning saying "You are about to leave this post unsaved"

Set generic reservation form for custom post type
I want to create a simple reservation (reservation.php) form for a custom content type (houses), i have created the reservation.php in the theme directory. The question is: How can i link to this general reservation form from the custom post type and pass the post id via `POST` or `GET`, so i can retrieve some information like post title, taxonomy, and so on. A plus would be do this with a nice permalink like `mysite.com/lake-house/reservation/` | If you have to make it a separate page that's available by visiting a permalink, you have to think what happens when user visits this page directly, without visiting the single post (house) first.
If you know how to handle it, the easiest way would be to make the reservations.php it's own page template and just link to that page from within your single post, while adding post ID as an argument.
The best way to do this, however, is, like kaiser suggested, include the reservation form in the single post template. | stackexchange-wordpress | {
