How to add a php custom page to Wordpress
I want to create a custom page for my Wordpress blog that will execute my php code in it, whilst remaining a part of the overall site css/theme/design.
The php code will make use of 3rd party APIs (so I need to include other php files)
How do I accomplish this?
N.B. I do not have a specific need to interact with the Wordpress API - apart from including certain other php libs I need I have no other dependencies in the PHP code I want to include in a WP page. So obviously any solution that didn't require learning the WP api would be the best one.please help me to slove this problem. | Please refer to the **Page Templates** section of the **Static Pages** Codex entry.
Essentially, you create a custom page template, named something like `template-foobar.php`, which will live in your Theme's root directory, or in a one-deep sub-directory.
Inside this template file, add the following:
<?php
/**
* Template Name: Foobar
*/
get_header();
// YOUR CUSTOM PHP GOES HERE
get_footer();
?>
Now your template is available to be assigned to any static Page you create. | stackexchange-wordpress | {

Restrict access to specific users
Is there a built-in function that would allow me to restrict access to registered users until the official launch date in Wordpress 3.4.2? The blog is self-hosted. | This should do it. Place it in your theme's `functions.php` or a plugin.
function tst($a) {
if (!current_user_can('edit_posts')) {
wp_die('You are not allowed to view this page');
}
}
add_filter('template_redirect','tst');
You can still get to the login page like normal by going to "/wp-login.php" or "/wp-admin".
Alternately, you could use `wp_safe_redirect` or `wp_redirect` instead of `wp_die` to send people to a "Coming soon" page or something like that. | stackexchange-wordpress | {

Is there any danger in deleting all transients?
I have a big site for a client, and as it is a really customized wordpress installation with lots of extensions on functionality, I can't use the caching plugins.
To improve the performance, I built a lot of the Site using transients (for example the navigation, the google maps with all the markers etc.), and leave the dynamic content dynamic.
The problem here is if I change anything, I have to manually delete the specific transient to see the current result. The site shows different menus and googlemaps when entered from a different channel, so I have like ten transients for each area.
Would you create a function where I delete those all at once (with a listing of the names of the transient), or is it okay to just delete all the transients on the site?
It's not really that urgent, but for future ddevelopment I would like to know if you had any problems with stuff like that, and how you manage all your transients.
Cheers, fischi | For development I would advise to always work with `WP_DEBUG` set to `true` and do the following:
$key = 'transient_key';
if( !WP_DEBUG && ( false !== ($transient = get_transient($key)) ){
/* Generate transient manually */
$expiration = 24*60*60;//How long to keep for
set_transient($key,$transient, $expiration);
}
In general - it should be fine deleting transients, as they should never be assumed to be in the database. | stackexchange-wordpress | {

Admin Subpages without Menu entry
I have added some pages to the WP-Adminmenu, with `add_menu_page` and `add_submenu_page`. The URLs for those pages look like `admin.php?page=my-plugin/admin/submenupage.php`. If I try to add a page now that has isnt registered to the menu and link to it with `<a href="?page=my-plugin/admin/add.php">` I'm getting a permissions error. Is there a way to add pages to the admin area without registering them to the menu? | The best thing you can do here is to call them with a `$_GET` parameter, and just register the first site to the menu.
so for example, when you registered `admin.php?page=my-plugin/admin/submenupage.php`, you have the `submenupage.php` structured like this:
if ( !isset( $_GET['section'] ) ) {
include('mainpage.php');
} else if ($_GET['section'] == 'hiddenpage1' ){
include('mainpage.php');
} // go on for every page needed.
This way you have your registered menuentry, but by clicking it from the adminmenu you always get to the `mainpage.php`. Just add the `§ion=hiddenpage1` or whatever you call your hidden pages, and you will see the "hidden" admin sections. | stackexchange-wordpress | {

Making the wordpress login form a jQuery dropdown
I'm using a plugin called `sidebar-login` to display a wordpress login form (it uses `wp_login_form`) in my sidebar. However, I feel like it the actual form (textboxes and labels) take up too much space and I'd like to hide it all in a slide-down jQuery div.
Basically, the user would click on a link called `"Login"`, which would make the login form fade in and slide down for the user to use. The problem is I need to add that link and wrap up the whole form in a div that I can apply a jQuery rule to.
What is the recommended way of doing this so I don't break any existing login procedures? | Try using SimpleModal Login. This should be exactly what you are looking for. | stackexchange-wordpress | {

Return one unique custom post type result when it shares a custom taxonomy in WP_QUERY?
Is it possible to remove custom post types from WP_QUERY that have a same shared custom taxonomy so that only one custom post type associated to that custom taxonomy is returned?
Example: Get an Items custom post type, returning only one Item per a custom taxonomy.
On a taxonomy-types.php page, I'm using WP_QUERY to get the Items custom post type. Then, wp_get_object_terms to get the Models custom taxonomy for the Items, and displayed that. However, I can end up with duplicate Models displayed because WP_QUERY is returning all Items and not one Item per unique Model.
Thank you for your help! | Thanks guys. I think I may have found a solution.
What I did:
* On `taxonomy-types.php`, get all Items for that type using WP_QUERY.
* Loop through them, use `get_the_terms()` to get taxonomy Model for each Item
* Still in the loop: use PHP's `in_array()` function and a `$model_ids` array for unique Model checking
* Still in the loop: if the Model is unique, store the Item id in an `$item_ids` array
* End that loop
* Use WP_QUERY to get Items with `'post__in'` set to the `$item_ids` array | stackexchange-wordpress | {

Using save_post to replace the post's title
I am using custom posts, and in these, I don't a need for the title.
This causes Wordpress to set the titles of my posts to "Auto Draft".
I'd like to change the title's value to something else, computed from other fields in my post.
How do I go about doing that using save_post or some other means? | This simplest method would be to edit the data at the point it's inserted, rather than updating it afterwards, using `wp_insert_post_data` instead of `save_post`. This works on creating a new post or updating an existing post without change. It also avoids the danger of creating an infinite loop by triggering `update_post` within `save_post`.
add_filter( 'wp_insert_post_data' , 'modify_post_title' , '99', 1 ); // Grabs the inserted post data so you can modify it.
function modify_post_title( $data )
{
if($data['post_type'] == 'rating' && isset($_POST['rating_date'])) { // If the actual field name of the rating date is different, you'll have to update this.
$date = date('l, d.m.Y', strtotime($_POST['rating_date']));
$title = 'TV ratings for ' . $date;
$data['post_title'] = $title ; //Updates the post title to your new title.

Merging Wordpress posts from different databases
I have development and production versions of my website (on the same hosting). I want to easily synchronize the content between these versions. On the production website, content is updated daily.
I cannot use the XML export function because duplicate posts would be created on the development website.
Currently both websites uses different databases, but if there is a solution that allows for usage of only one database I gladly will go through it. | If you never send/sync Production posts to live.
Then just pull/copy the live database to the development database via mysqldump (or similar) and use wp-config vars to force the site and blog URL.
Use the following in the dev versions wp-config.php to force the URL's
define('WP_HOME','
define('WP_SITEURL', '
You may as well sync the entire database, rather than just posts, so then you get all the post revisions as well as any plugin configurations/data.
This is my normal method of developing a live site, locally. (Grab live DB drop Dev DB import Live DB into Dev) (The only fun bit is sending specific plugin configs up to the live site from the dev site) | stackexchange-wordpress | {

How to delete custom field "suggestions" from dropdown list
When you use a standard custom field in WP you have to write the name of the cusotm fields the first time.

Why does running get_the_excerpt() when generating JSON file take 28 seconds vs. 599 milliseconds without it?

How to add to cart via AJAX Woocommerce
I have been searching for a while, this. I want to add an item via AJAX. When you add an item to a cart in Woocommerce the page reloads with the GET parameter `add-to-cart="The current product ID"`.
I want to do it via AJAX. In the admin area is a checkbox to enable that featured that is labeled "Enable AJAX buttons to add to cart on the product list"
But it doesn't do anything, it stills reloading the page. | are we talking about the single product view or the product archive pages (shop,categories)?
because the text beside the checkbox/option states, roughly translated:
_»activate ajax-checkout-button on product archive pages«_
and on all the installations i did so for, that is the way its working - ajax checkout on the archives, but not on the single view.

Add custom field automatically (add_post_meta) with value based on number of words of article

W3 Total cache "empty all caches" and no stylesheets render
I have the w3 Total cache plugin installed and so far its been great as I'm sure you will all agree, so thanks to the author for an amazing plugin. However, I used the "empty all caches" button on the general settings page and when the plugin is activated none of my stylesheets are loading so the page appears without any styling?
I have to deactivate the plugin for the stylesheets to load. How can I reactivate W3 so that the stylesheets all render properly again? | W3 Total Cache combines .css files. If you do not want this to happen, deactivate the option on the page `wp-admin/admin.php?page=w3tc_minify`, section CSS `enable`.
If this option is not available, try setting the `minify` settings on the main page of W3 Total Cache to `manual`.
This Caching Plugin is awesome - but you have to tweak the settings quite a bit, if you are new to it mostly through trial and error, to get to the best result.
Please be sure to check your page a few times after you finished your settings, and also check it in logged-out mode, I had a few problems with sites being processed right on their first call, but broken afterwards.
A really tricky thing is the javascript-combining and minifying - if you are not 100% sure what you are doing, it can make your site a mess. But if you do - hello PageSpeed :) | stackexchange-wordpress | {

How to remove tag base from permalinks

How do I programmatically generate a 404?
How can I get something like this to work?
// in a plugin / theme:
// This imaginary function will make WordPress think that the
// current request is a 404.
// Ideally this function could be ran anywhere, but realistically it
// will probably have to be before the template_redirect hook runs.
generate_404_somehow();
// later...
add_action('template_redirect', function() {
// should be "true"
var_dump(is_404());
});
Basically under certain conditions, I want to tell WordPress to show its 404 template (which I can hook into later if I want) instead of the template it's about to load (eg a page or archive).
I know I could just do a `302` redirect to a non-existent page but that's very messy. I could also send a `404` HTTP header manually, but then I can't use WP's nice 404 page (I already have things that hook into `is_404()` that need to get fired at the right time). | function generate_404_somehow() {
global $wp_query;
$wp_query->is_404 = true;
}
add_action('wp','generate_404_somehow');
Of course, that will send all of you page to the 404 template. I don't know what the conditions are that this should fire or not fire.
Or to be more cautious (see comments) ...
function generate_404_somehow() {
global $wp_query;
$wp_query->set_404();
}

Thanks | Since the question is tagged woocommerce, i'm assuming that it's a product CPT created by woocommerce wordpress plugin. This answer doesn't apply if that's not the case.
The products categories is not normal categories, they are a custom taxonomy created specifically for products which is just labeled as "Categories".
You should go through the woocommerce documentation to find some function that would do this for you, if you don't find anything you can try an alternative solution. For that, first you should know the name of the taxonomy. You can copy it from inside the url in your browser when you visit categories edit screen in the backend.

Update exisiting site to 3.5 release candidate

reason of splitting theme files to multiple files
I can create my theme without splitting it into separate files. Why do theme developers split WordPress theme into a few single files like header.php sidebar.php and etc? | You need that for child themes. If you have a separate `header.php` a child theme can use its own `header.php` and override the parent theme’s file. Plus, `header.php` and `footer.php` are used in `wp-signup.php`.
Another reason is readability: Putting all the code for a theme into just one file gets very messy very fast.
A use case for a compact theme is testing and debugging: My Mini Theme uses just `index.php` and `comments.php` for output. Whenever a plugin doesn’t do what I expected I use that theme to be sure it is not a theme issue. | stackexchange-wordpress | {

Extending a CPT by Created by another plugin

How do you extend a CPT created by another plugin? Is there an official hook that I'm not seeing to be able to modify an existing CPT? | I am not sure exactly what you are trying to 'extend', or how you want to extend it, but you can alter posts types with `add_post_type_support`, `remove_post_type_support`, and a few other functions.
You can add metaboxes to the post type with `add_meta_box` setting the `$post_type` argument to the name used to register your post type. (Examples are on the Codex page) Unless the original plugin provided a hook you won't be able to directly alter its metaboxes but you can use `remove_meta_box` to remove existing boxes and then add back a near clone of the metabox with your changes.
You will have to hook into `save_post` or [`admin_action_{$_REQUEST[action]}`]( to save any additional fields you create. | stackexchange-wordpress | {

### Deregister the Default Meta Box and Make a Custom One
@MikeSchinkel answer to this question is very detailed and thoughtful: Adding Page Attributes Metabox and Page Templates to the Posts Edit Page?

This other Q&A ( How To Change Custom Taxonomy To Radio Buttons ) provides an example of _replacing_ the Taxonomies Meta Box.
### Add Ajax to the Custom Templates Meta Box
In this answer, there's an example of custom meta box that runs an Ajax call, that in turn makes a database query to modify an attachment parent.
To do the Page Template live switch, it would be a matter of modifying the table `wp_postmeta` where the current template value is stored.

Authors' Links on Homepage Not Going to Author Post Pages
This problem only occurs with the articles/blog posts on the homepage of the site, readbuzz.com.
On the homepage of the site, the author's name is supposed to link to that particular author's post page, where all the blog posts the author posted on the website will show up. Instead, each name that shows up links to the homepage.
Yet, when you click and go into any of the posts on the homepage, then checked the author's link, it takes you directly to that author's post page.
I know I need to include this function, but can't seem to find the place where I need to edit this: link
**UPDATE: The code below is the correct code, in several different PHP files. Currently need to know how to write it using the the_author_posts_link();**
<p class="postAuthor">By <a href="<?php the_author_meta('user_url'); ?>"><?php the_author(); ?></a></p> | > The code below is the correct code, in several different PHP files. Currently need to know how to write it using the the_author_posts_link();

> <p class="postAuthor">By <a href="<?php the_author_meta('user_url'); ?>"><?php the_author(); ?></a></p>
>
Just replace this:
<a href="<?php the_author_meta('user_url'); ?>"><?php the_author(); ?></a>
With this:
<?php the_author_posts_link(); ?>

<a href="<?php echo get_author_posts_url(get_the_author_meta( 'ID' )); ?>"><?php the_author(); ?></a>

How can I use get header from within my plugin?
I'm writing a plugin to do some specific business logic - edit records for authenticated users, etc.
Rather than having the overhead of a form processing plugin that uses stuff in template tags. I've created a rewrite do redirect like:
/mylisting/909 ->/wp-content/themes/myplugin/edit.php?id=909
Which seems to make sense as I'm keeping the very specific logic to an individual plugin.
The problem is, I want to use my theme within my plugins files as they'll be output in the site's frontend and as such I want them to have the same look and feel.
So I've tried get_header(); include('../mytheme/header.php')
As well as including wp-load.php
...None of which work (I get fatal errors)
Any help? | > I've created a rewrite do redirect like:

There is a better way: Create an endpoint, use your code in a callback handler for the new URL. You get the whole theme environment for free here: `get_header()`, sidebars, menus etc.
Do not forget to call `exit;` at the end of your endpoint, othrwise WordPress will use the theme files again. :)

get_terms on save_post hook
Usually, if I want to check for some attribute of the post I'm about to publish, I will check like this:
$post_title = $_POST['post_title'];
post_title is the name of the title field in the edit window.
I thought I'd apply the same logic to the taxonomy meta box.
$formats = $_POST['tax_input[formats][]'];
Essentially, I'm trying to check if a specific taxonomy term is being selected when I publish a post. | You're on the right track.
When you do something like this in a form..
<input name="tax_input[formats][]" />
You create levels in the `$_POST` array.
So you'd get the formats array like this...
<?php
$formats = $_POST['tax_input']['formats'];
Full example...
<?php
add_action('save_post', 'wpse74017_save');
function wpse74017_save($post_id)
{
// check nonces and capabilities here.
// use a ternary statement to make sure the input is actually set
// remember that `save_post` fires on every post save (any post type).
$formats = isset($_POST['tax_input']['formats']) ? $_POST['tax_input']['formats'] : array();
// do stuff with $formats

How to List Events by Year and Month Using Advanced Custom Fields?

Getting only direct child pages in WordPress with get_pages
I am trying to fetch all direct children of a page. But I am getting all children and grand children as well. Any ideas?

{
$post_tempalte = the_page_template_part();

Custom page sidebar using Template dropdown box
i am wondering how i go about making a Template for some of my pages to use a different sidebar? I have created the widget like this:

'id' => 'ourPat-sidebar',
'name' => 'ourPat Sidebar',
'before_widget' => '<div class="widget %2$s" id="%1$s">',
'after_widget' => '</div>',

'after_title' => '</h3>'
));

Then i go into my Widget panel and its displayed just fine. Then i proceed to add text to it in order to form the sidebar html.
!widget menu
However, when i go to my Page menu and create a new page, i do not have the choice to use the custom widget code?
!theme
So i must be doing something incorrect since its not in there.
To recap, i'm just looking for a way for different pages of mine to use a different sidebar using a custom widget i made. | In order to accomplish this you will need to also create a separate page template to use. You may need to double check your template head information.
Example:
<?php
/*
* Template Name: Your Template name
*/
?>
This has to be put at the top of the page template. Then within the custom page template you will need to call the custom sidebar that you have.
You will need to put this in the template where you want your sidebar to go:
<?php
if ! dynamic_sidebar( 'ourPat Sidebar' ) ) :
?>
You need to add widgets for items to show in this area. To add for this area add widgets to "ourPat Sidebar".

How to specify expiration of cacheable resources?

What is the proper way to get logged in user id in a plugin?

Exclude categories from homepage but not from sidebar
I would like to exclude categories from my homepage, but I want them to still display in the sidebar shown on the homepage, how can I do that?

function exclude_category_home( $query ) {
if ( $query->is_home ) {
$query->set( 'cat', '-5, -34' );
}

}

How to set a custom post type to not show up on the front end
I use a custom post type in one of my sites for image slideshows. I have publicly queryable set to false/off but when Google crawls my site I see 404 errors for the URLs for my slideshows. I thought that by having publicly queryable off Wordpress would not create those front end URLs.
How can I completely turn off the front end URLs and pages for my custom post type?
## EDIT
By adding `'public' => false`, `'has_archive' => false`, `'publicly_queryable' => false`, and `'query_var' => false` I have successfully gotten rid of the 404 errors in Google. I also added the function provided by @Norcross just for good measure. | Another option would be to set a 301 redirect for all the slideshow CPTs to redirect somewhere (like the home page).

Restrict access to the Trash folder in Posts
I want to restrict users from deleting posts permanently. How do I restrict access to the Trash folder in Posts? This is the only page were the users can delete their posts **permanently**.
The only solutions that I have so far is:
1) Adding this to stylesheet:
li.trash {
display: none;
}
But both me and you know that this is a dummy fix and more importantly, it just hides the link that goes to the Trash folder for **all** users.
2) Remove the capability `delete_posts` for none-editors. The problem with this is that the users will not be able to move their posts to the trash folder (which is a feature that is essential for my platform).
Do you know of a better solution? | With the filter we prevent the `Trash` link from being printed.
And with the action, redirect back to the post listing page if the user tries to access the URL directly (`/wp-admin/edit.php?post_status=trash&post_type=post`).

How to Create Editable Blocks of Text for the Homepage?
I'm making a site based on WordPress. It's not going to seem a blog or WP. Just a website. So WP acts like backend where the client can edit the text blocks.
Question:
* How can I put block of text on my designed template wich users can edit from admin panel?
Let's say something like this:
, how do you fill them from admin panel? Or specific text from header or footer. Do I have to create 3 posts, and reference them on template through `get_post($id)`?
Which is the best way to do it? | You have multiple options here, depending on the amount of flexibility you want to give the editor of the text blocks.
1. Create a custom loop with `WP_Query`. See our examples and the Codex page for usage. Then you print the excerpts of the page these boxes are linked to.
You can use attachments (images) and the full formatting here.
2. Use widgets. See our examples and the Codex page. Limited formatting because the visual editor doesn’t work too well in widget forms.
3. Use a custom navigation menu and print the description.
You can combine these methods: Use widgets for header and footer, `WP_Query` and page or post excerpts for the other boxes. | stackexchange-wordpress | {

a one-off rewrite rule
I have _one_ page that I need to change the URL for.
Currently, the page resides at example.com/departments/human-resources/
(human-resources is a sub-page of /departments/ )
My client wants to maintain the legacy url for the hr department which is:
<
How can I rewrite any request for `^/hr/?$` to `^/departments/human-resources/$` but keep the URL the same?
That is, nobody will ever see /departments/human-resources/.

RewriteRule ^index\.php$ - [L]

Referencing parent theme image from child theme
Apologies if this has been answered elsewhere, but I've had some trouble finding the solution via Google.

How to set different cookies for logged in admin users and logged in non admin users?
