Custom priority with the_content filter based on user input
Currently, in my plugin Contextual Related Posts, I have an option to automatically add the related posts to the content using
add_filter('the_content,'ald_crp')
I know I can change the priority of the filter by adding a number greater than 10 (which is WordPress default).
add_filter('the_content,'ald_crp',20)
However, what I would like to do is let the user set the priority of the filter from within the options page which I can use and set the_content filter accordingly.
The plugin already has its own settings page.
My plugins doesn't use classes. It uses functions.
Any suggestions / code samples for this? | Save the priority in your options and pass that value to your `add_filter`:
add_action( 'template_redirect', 'wpse_81687_prepare_filter' );
function wpse_81687_prepare_filter()
{
$my_options = get_option( 'my_options' );
$priority = isset ( $my_options['content_filter_priority'] )
? $my_options['content_filter_priority']
: 10;
add_filter( 'the_content', 'ald_crp', $priority );
}
In my example I register the `the_content` filter during `template_redirect` because it is not needed earlier. You don’t need the filter in `wp-admin` or a login page.
You could even use `the_post` as hook instead of `template_redirect`. But then … another piece of code might call `echo apply_filters('the_content', $some_text );` without calling `setup_postdata()` before. | stackexchange-wordpress | {

Difference between Option_Group and Option_Name in Register_Settings
I think the title pretty much says it all! I'm working my way through various tutorials on how to add an options page to my test plugin and am struggling to understand the `Register_Settings` function.
Every tutorial I have found quotes the codex for the arguments then uses the same text in the `Option_Group` and `Option_Name` argument. Can someone explain it to me please? | The codex defines the function as:
register_setting( $option_group, $option_name, $option_validate_function );
* `$option_group` is settings group name. Use when displaying on a settings page for example
* `$option_name` is the database entry name
* `$option_validate_function` is the callback for this database entry/this option.
Most codex tutorials use an array of data in one `$option_name` but that's not required (just more efficient in terms of table rows). You can add multiple options with unique names under the same option group.
**Usage**
* `$option_name` is the name you access when using `get_option( $option_name )`.
* `$option_group` is the group name used when creating security with `settings_fields( $option_group )`. | stackexchange-wordpress | {

How to make page template with admin able to select NextGen Galleries to be part of the layout?
I'm trying to make a product page template, editable by client, which will have 3 different NextGen Galleries per page.
In the product page admin area, I want the client to be able to select which 3 NextGen galleries to display, and in which order.
What do I put in my template page, and (I'm assuming) functions.php?
Here's a mockup of an individual product page how I want it to be, so you can see what I mean: <
I'm customising a theme, in which all the 'About the Product' fields etc are in the page template already, I just want to add selectable NextGen Galleries.
I've tried googling this but I'm not sure of exactly what terminology I should be searching for, so any advice would be appreciated. Thankyou! | You can add galleries directly to a template by calling do_shortcode() to run the gallery shortcode.
<?php echo do_shortcode('[nggallery id="1" template="example"]'); ?>
Edit: sorry, writing decaffeinated so short attention span :)
Add some custom fields to your product pages to let your client pick which gallery goes on that product. If you like, just use the Advanced Custom Fields plugin and its friend the NextGEN Gallery Field add-on, which will let you add drop-down lists of gallery names to your edit pages.
Then in the template, get the value of each custom field and load the gallery using the shortcode as above, like this (replace 'gallery1' with your custom field names):
<?php
$gallery = get_post_meta(get_the_ID(), 'gallery1', true);
if ($gallery) {
echo do_shortcode("[nggallery id='$gallery' template='example']");

Silently register plugin pages
I am developing one of my first plugins, and have come across a error:
> You do not have sufficient permissions to access this page
The plugin has a wizard that uses several forms, obviously I don't want people selecting later forms using the menu.
Is there a way to "silently" register a page? Basically, register the page without having it appear in any menu.
(I don't like my work around) | The mighty Codex holds the answers:
1. If you're running into the »You do not have sufficient permissions to access this page.« message in a `wp_die()` screen, then you've hooked too early. The hook you should use is `admin_menu`.

Help with this custom field conditional if no field is set display nothing
I'm using the code below to display an image if the swap_select custom field value is true. If it's no it displays nothing. However when posts are first created no custom field exists. So what would the conditional be to account for no custom field at all and in that case display noithing?
<?php
$swap_value = get_post_meta($post->ID, 'swap_select', true);
// check if the custom field has a value
if($swap_value!= 'no') {
echo '<img class="" src="thumbs/speechbubble_pink.png"/>';
}
else{
}
?> | I prefer `empty` for this because it considers a lot of things to be "empty" besides just an empty string, and that is the behavior I usually want. Be aware of that though.
I am not 100% sure what you are doing but...
if( empty($swap_value) ) {
// runs if no $swap_value, or an empty value
}
// OR
if( !empty($swap_value) ) {
// runs if $swap_value is set to something

Text snippets shared across posts
I'd like to add a "fast facts" section to a wordpress site - an area in the sidebar where snippets of text are rotated.
Where is the best place to store things like this? Widgets don't really allow repeated items grouped in a good way & i don't want to add a post type as that would be available as a page with a URL | It sounds like you _do_ want a custom post type, you just want to set the `public` argument to `false`. The `register_post_type()` has lots of arguments that will let you do everything you probably want. Along with `public`, you'll probably set `has_archive` to `false`. Setting `show_ui` to `true` will allow you to manage the posts in the backend.
If you want to group the "fast facts" in any way, register a taxonomy to go along with your post type.
Obviously, you'll still have to fill in some blanks and write a widget to put into the sidebar, but I think this answers your main question. | stackexchange-wordpress | {

Date in the URL with The Events Calendar
I am somewhat of a Wordpress beginner so please excuse any ignorance.
I have installed the plugin The Events Calendar ( and it works pretty much perfectly. One issue I have is the URL format for an event, which based on the URL slug is `/upcoming-event/[event title]/`. If I have multiple events of the same name, the URL looks like `/upcoming-event/[event title]-2/`.
This is undesirable, I would prefer to have URLs more like that possible with posts `/upcoming-event/[year]/[month]/[event title]`. On a whim, I attempted to copy in the format used for posts `/%year%/%monthnum%/%postname%/` but alas, no luck.
I had a quick check to make sure it wasn't a PRO feature but it doesn't appear to be. So does anyone know if this is possible somehow? | You could just try to change the slug to the value you need for each event. The problem arises if you have the same event twice (or more) in the same month though. You will need to create a new title for the event.
you can try this plug-in: <
It might help you with changing the permalink structure for the events so you wont need to keep changing the slugs when you create events. But I don't think that will help with removing the number after the event title as that is the way WP core works for duplicate posts.

Performance Gains of Relational DB Setup
Our team is working on the 3rd of large WP sites for a client, and contrary to most "typical" WordPress setups, our projects are generally experience lots of requests, data pulls, and general content - if you saw (and could see) our site, you would be hard [word]pressed to know it was even a WP site. I've been examining performance, particularly on the database level, and we've implemented some basic caching for larger data sets.
My question is - would we gain much in performance by taking some steps to improve the database in terms of structure? Such steps would include:
* converting tables to InnoDB (our default is MyISAM)
* setting up proper foreign-key relationships, such as wp_postmeta.post_id => wp_posts.ID
Those are the only ones I've come up with so far, but there may be others. I've done work with various SQL engines, but I'm by no means a master of optimization on the database level. | I can't comment on foreign keys but moving to InnoDB would be a good idea for large scale.
Although it's a little slower than MyISAM, it does row level locking, rather than table level locking. As a result saving a post or doing a lengthy operation or query won't lock the posts table, freezing the entire site while it waits for the table to unlock.
For very large multisites it may be desirable to investigate HyperDB, which is what wordpress.com uses.
Not DB related but you may want to look into the short init definition for AJAX calls | stackexchange-wordpress | {

How to filter out an iframe from feed
There is some iframe inside post content and I want to get rid of that iframe when the rss feeds are generated. To generate rss feeds, I'm showing full post content.
I started looking at `strip_tags()` but it does pretty much the opposite: strip everything unless the desired tags.
I'm wondering that maybe there is some hook and some wordpress-y form of solving this issue.
I know I should do something like this:
function rss_noiframe($content) {
global $post;
// filter out iframe here
return $content;
}
add_filter('the_excerpt_rss', 'rss_noiframe');
add_filter('the_content_feed', 'rss_noiframe');
But I'm lost at this point. Any ideas?
On demand by EAmann, here is some example code that isnt modified at all (it still appears in the feed, in fact):
<iframe src=" frameborder="0" scrolling="no" width="500" height="375"></iframe> | One potential option is to use `preg_replace` to do a regex match on your content and replace the iframe with empty space.
So this function:
function rss_noiframe($content) {
$content = preg_replace( '/<iframe(.*)\/iframe>/is', '', $content );
return $content;
}
add_filter('the_excerpt_rss', 'rss_noiframe');
add_filter('the_content_feed', 'rss_noiframe');
Should automatically convert any instances of `<iframe src=...>...</iframe>` to a blank. | stackexchange-wordpress | {

Optimal solution to develop a wordpress theme?
What i was doing previously, are as follows -
1. I copy the wordpress base theme (like twentytwelve in wordpress 3.5)
2. Rename the folder and converted index.html of my HTML to index.php for wordpress theme.
3. Replace style.css with my current style.css.
Is it the right way of theme development or some else better technique can be applied for theme development ?
I google a lot for the theme development but 99% tutorials are only using index.php , style.css only(some only header/footer etc) although in the new version of wordpress 3.5 twentytwelve I found there are too many files in the theme.
So for the client case I dont want to leave any core theme functionality provided these dummy themes, so is it the correct way I am following or for the best way I need to design and code for each file ? | I like to do this as follows:
1. Go to underscores.me, fill out the theme name, and download the theme.
2. Strip out the parts of this (somewhat clean) template that don't want to use.
3. Start building your own template with the functionality that you wrote.
This way you will have a clean template to start with, and no core theme functionality provided by the theme you decided to use as a dummy.
I don't know exactly if there is any "right" way to build your own theme, only that the Codex insist you use the WordPress Coding Standards, CSS Coding Standards and that you follow the design guidelines.
I think that, except of the parts of the Codex a developer is free in how to develop a theme. | stackexchange-wordpress | {

Pull the content out of a page

I have a page template named page.php

<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', 'page' ); ?>
<?php comments_template( '', false ); ?>

but this just send me a comment field.. i need the text in the page
and i need the header | While inside a query loop, this function will output the current posts title:
the_title();
This function will output the content:
the_content();
What I suspect has happened however is that you are instead calling `get_template_part( 'content', 'page' );` and expecting it to output the content for the page, when what it's actually doing is checking if there's a `content-page.php`, and including it if it's present, if not it checks for `content.php` and includes that, and because neither exist, it's doing nothing, and so you get no content.
For more details on what `get_template_part` actually does, look here:

How can i do custom author list?
My blog have many author. I can list all author.
All Author list:
<ul>
<?php wp_list_authors('exclude_admin=0&optioncount=1&show_fullname=1&hide_empty=1'); ?>
</ul>
But I want to sort in a special way.
For Example im currently viewing Tech category page, I want a list of author with these id (3,10,12). I will use this code in sidebar widget. And i need a metabox for select author id.
Regards | I assume that you would be providing the author IDs in the widget options. And that the authors would be displayed in the order they were listed.
Assuming the input would be -> 3,10,12
You can have the following code to display the authors with that user ID in that order:
$user_ids = "3,10,12"; //this is assuming you already have the value stored in a variable
//convert the comma separated string into an array
$user_ids_array = explode(",", $user_ids);
//display the list of users
echo '<ul>';
foreach( $user_ids_array as $id ):
$user = get_userdata( $id );
echo '<li>'.$user->ID.' '.$user->display_name.'</li>';

You just have to take one more step, create the file in the Theme directory (the same folder where your `single.php` is located).

Can I do it with `WP_Query($args=array())` class? | Basically, I am reading right out of the Codex page for `WP_Query`.

send users logging in from wp-login.php directly to home page of site, rather than dashboard
I am currently using a plugin called Sidebar Login which allows users to bypass the dashboard and go directly to the site. However, when users login via `/wp-login.php` (e.g. when they click on their verification links in their emails), they are once again sent to the dashboard. I would like for users to be able to click on their verification links and have them directed to the home page of the website where they can sign in through the sidebar login I have set up. Is this possible? | You can achieve this by using the Plugin Peter's Login Redirect. It allows you to send users to a specific page after login, based on the user capabilities. So you can allow administrators to go to the admin section, while members are redirected to the front page.
If you want to prevent users from ever seeing the admin, insert something like this to your `functions.php`, depending on which users you want to allow in the admin you may have to change the capability.
if ( is_admin() && !current_user_can('manage_options') ) {
wp_redirect( get_bloginfo( 'url' ) );
}
You can also hook a redirect function to `login_enqueue_scripts`, to send every user calling the login page to the homepage (same structure as above). | stackexchange-wordpress | {

Does search.php autofilter The Loop?

I did not put any filters with $_GET in the loop, is it possible search.php automaticly filters the loop to get results that matches my search??? | The loop doesn not display _the latest posts,_ it just shows the posts the main query has found. On your search page the main query returns search results, and you can change its order (we have plenty of examples for that on our site).
WordPress looks for the parameter `s` or `/search/` in the request URI and decides to do a search query then. That’s what you see as results. You don’t have to do anything more, if you are happy with those results. It happens automatically. | stackexchange-wordpress | {

But this is not true. I am using a custom function `wp_my_own_link_pages()` which is a replacement for `wp_link_pages()`. It generates pagination with a compatible HTML structure for the theme.
Did I miss something required? How can I make this work? | First, this question should be asked on the Theme Reviewers mail-list, not at WPSE. If you want official answers, you should use the official communication channels.
But to answer your question in brief: Themes that implement core features/functionality are **required** to support the core implementation of those features/functionality.
Thus, the requirement to use `wp_link_pages()` is... a requirement. Note that if you need to modify the HTML markup of the generated pagination links, you can use the arguments passed to `wp_link_pages()`.

Thank you! | If you're on a singular page, sometime after `init` and all the query variables have all ben set up you can use `get_queried_object_id` or `get_queried_object`.

Check user's role and store in variable
I am using **custom user roles** which I create and assign by using a plugin. I was wondering how I could retrieve the user's role and store it in a PHP variable.
What I am trying to achieve is something like this:
Let's say I created 3 custom user roles: `role_apple`, `role_banana` and `role_carrot`
if ( 'role_apple' === $user_role ) {
echo 'User is an apple';
}
elseif ( 'role_banana' === $user_role ) {
echo 'User is a bannana';
}
How this can be achieved? | You don't need to store anything, just check the current logged in user via `user_can`:
global $current_user;
get_currentuserinfo();
if ( user_can( $current_user, "role_apple" ) ){

wordfence scan warning on W3 Total Cache

Wordpress admin bar showing pending comments which cannot be selected or modified after deleting parent page

Get author custom image field URL to display on post page?

Reset Roles (or undo role changes on theme change)
I am creating a theme that deletes some user roles that are not necessary and creates others. (It deletes author and contributor and renames subscriber).

2. If capabilities and roles get updated, on every Wordpress update I'll have to manually check I'm adding the right capabilities back.

Add whitespace between Chinese and other letters

Is it possible to get a user with just the password field?
I tried doing something like this:
$user = $wpdb->get_row('
SELECT *
FROM ' . $wpdb->users . '
WHERE user_pass = "' . wp_hash_password('password') . '"'
);
But the `wp_hash_password` function generates a different string from the one in the database, is it possible?
What I'd like to do is have a custom form in my template that just asks for a password (think of it like the username/pwd screen to the WP admin area without the username) so I'd hash whatever the user inputs, compare it with my DB and if it matches take that user and log him in. | Here's what I ended up doing in case someone else need a similar functionality:
// Simple text password
$client_password = $_POST['client_pwd'];
$users = get_users();

// If it matches log the user in
if (wp_check_password($client_password, $user->user_pass)) {
$user = wp_signon(
array(
'user_login' => $user->user_login,
'user_password' => $client_password
)

WP_Query arguments: Loop through custom post type - get all entries except excluded meta_key?
Can't seem to find out what I'm doing wrong.
$args = array(
'post_type' => 'wr_event', // my custom post type
'posts_per_page' => -1, // show all posts
'meta_query' => array(
array(
'key' => 'event_announced', // a custom field either "on" or "off"
'value' => 'on',
'compare' => 'NOT IN'
)
)
);
$loop = new WP_Query( $args );
So all I want to do is loop through all `wr_events` but if an event has the custom field `event_announced` (a checkbox) checked I'd like to exclude it.
Ideas? I tried setting "on" or "off" for the `value` and tried different solutions for `compare` | Your current query will select posts that have a value in the key `event_announced` which does not equal `on`. What I think you want is `NOT EXISTS`, and you can omit `value`, since you are querying for posts that don't have the key, hence, it will have no value.

Delete all associated media when custom post type removed
Basically I have so many images associated with custom post type that I need to be able to safely delete all related media on removal from trash.
Is there a safe way of doing this? | Is your post to image association custom?
If not attachments should be automatically deleted by Wordpess.

Disable sticky option for specific categories

Wordpress "Loop" with large set of results
I'm not sure the appropriate terminology but I have a wordpress "loop" for a custom post type that has roughly 300 results that all get displayed on a single page (no paging). The causes an enormous load on the DB server because for every "post" in the "loop" there are like N database calls (the_title, has_post_thumbnail, get_post_thumbnail_id, the_content, get_post_meta, etc..). What is the wordpress way of optimizing this? For something like this do most developers just drop to doing queries with $wpdb or is the wordpress way to cache the page and move on? I looked at doing straight $wpdb sql queries but grabbing the relevant data (especially images associated with the post) is less then intuitive. | You can use the Transients API to cache the entire HTML output so the queries are not done every time the page is loaded:
$transient = 'my-300-posts';
$timeout = 3600; // 1 hour
if ( false === $out = get_transient( $transient ) ) {
$args = array( YOUR ARGS GO HERE );
$posts = get_posts( $args );
if ( $posts ) {
foreach ( $posts as $post ) {
$out .= get_the_title( $post->ID );
$out .= // whatever else you want to output...
}
}
if ( $out ) {
set_transient( $transient, $out, $timeout );
}
}
echo $out;
However, you're still serving 300 post thumbnails on one page load, which is a lot of data to transfer.
(You also need to delete the transient on the `save_post` and `delete_post` hooks)
Maybe you'd be better off with infinite scrolling? It's an option in the Jetpack plugin. | stackexchange-wordpress | {

Child Theme Variables

I put the code into functions.php:
function brickAlign() {
$a = "true";

function brickAlign() {
$a = "true";

return 'false';
}
