Where's The Best Place to use Register_Shutdown_Function()?
I want to use Register Shutdown Function to track Fatal Errors, my question is, where's the best place to call this so it hits both WordPress, Plugin, and Theme Fatal Errors? | WordPress core register a shutdown function on its own (source) the function `shutdown_action_hook` registered to be ran on shutdown, call
do_action( 'shutdown' );
and little more (source).
So, if you want to register a shutdown function in _WordPress way_ just add your function on 'shutdown' hook:
add_action( 'shutdown', 'my_shutdown_callback' );
function my_shutdown_callback() {
error_log('Goodbye');
}
Where to put this code is not very important, a plugin, a mu plugin, functions.php, it doesn't matter, it will run always on shutdown...
Of course register it as soon as possible allows you to catch early errors, so using a mu plugin you can catch errors that happen on plugins init. | stackexchange-wordpress | {

username_exists() function can't be access without logging in
I'm using the following function in functions.php to check if a username exists in the DB
function check_username() {
$username = $_POST['user'];
if ( username_exists( $username ) ) {
$return['user_exists'] = true;
}
else {
$return['user_exists'] = false;
}
echo json_encode($return);
die();
}
add_action('wp_ajax_check_username', 'check_username');
The problem is that the `username_exists()` function only seems to work if a user is already logged in and checks a username. I tried to check for an existing username without logging in and it just returns `undefined` for me.
I have no idea why this is happening and can't find any documentation about this issue.
My question is, how do I enable a user to check if a user exists without having to log in?
Thanks | When using Ajax API, and you want to make the ajax callback available for non-logged users, you need to add 2 actions, `"wp_ajax_{$action}"` and `"wp_ajax_nopriv_{$action}"`.
Using only the first action, the callback will be called only for logged users, using only the second it will be called only for non-logged visitors.
Try this:
function check_username() {
$uname = filter_input( INPUT_POST, 'user', FILTER_SANITIZE_STRING );
wp_send_json( array(
'user_exists' => get_user_by( 'login', $uname ) ? 'true' : 'false'
) );
}
add_action('wp_ajax_check_username', 'check_username');

Wordpress capabilities and restricted categories access
I've a Wordpress blog to share content with some people only. Users has to login to access this website.
I created new roles and new capabilities on this blog.
I've got some articles which belongs to a certain category that I would like to share only with people with a certain role.

(

https redirect hell (adding www)

Thanks! | In case anyone has a similar problem the answer was a lot more complicated than I thought. It turns out that NameCheap (my hosting company) installed a different SSL cert incorrectly.

Show meta box only when post is being published first time
I'm creating a WordPress plugin where it is required to show the meta box only when a post is being published for the first time.

Modify main loop in taxonomy archive page
Is there a way that I can modify the main loop in a single taxonomy template, but leave it untouched in every other template?
In this case, I have a custom post type called "Events" which in turn has a custom taxonomy called "Region". What I want to do is, instead of listing each custom "Events" post chronologically by post date I want to order it by a custom meta value (In this case `event_date`).
I only want to do this in my `taxonomy-region.php` template and leave any other instance of the main loop untouched. | You could hijack the `$query` just before fetching the posts.

Custom post type - two taxonomies
I would like to have a page dedicated to gathering plants in nature. So lets say that in march and april it is possible to pick nettle leaves, while in september and october its root should be gather.
So I did a custom post type for a plant and two taxonomies - Months and Plants-part.
Is there a way to connect both taxonomies on the same post while still staying separate? Because I would need to fetch data based on a month.
Ocasionally, there would be a need for multiple data for same plant, for example
Some plant / latin name / tips
- roots -> october
- fruit -> march, april
- leaves -> august
- seeds -> september | It makes sense that each attribute should be a taxonomy - eg roots, leaves, seeds - but you don't need a separate taxonomy for months. Instead, the months should be the terms of these taxonomies.
The second argument to `register_taxonomy` in each case should be the name of your custom post type. This will mean you'll get a box for each taxonomy on the 'Edit Plant' screen. And in each box, a list of months (you'll need to populate this yourself).
Obviously this makes it straightforward to get the months of interest with respect to a certain plant, but it's perfectly possible to go the other way. For instance, if you wanted to get all of the plants which were of interest in a given month, you could construct this query quite easily. | stackexchange-wordpress | {

Removing user contact methods works from functions.php but not from a plugin
I'd like to remove user fields and I used this code:
add_filter( 'user_contactmethods', 'newfields' );
function newfields( $user_contact ) {
unset($user_contact['facebook']);
unset($user_contact['twitter']);
return $user_contact;
}
If I use this code in `functions.php` of my theme, it works, but if I use this code in a plugin, it doesn't work.
Why? How can I resolve it? | This could be the matter of adjusting the _priority_ of your filter callback, since the plugins files are executed before the `functions.php` theme file. That could explain why it works in your `functions.php` file, if the priority is the same.
When you add the code snippet to a plugin, it might be executed before the other plugins that use the same filter.
The default priority is `10`, so you should try something higher in your plugin code, for example:
add_filter( 'user_contactmethods', 'newfields', 99 );
or even
add_filter( 'user_contactmethods', 'newfields', PHP_INT_MAX );
if you want to be absolutely sure your filter callback is the last one to be executed - assuming the other plugins are not using `PHP_INT_MAX` as well.
But better yet, just check the priority the `user_contactmethods` filter callbacks the other plugins are using. | stackexchange-wordpress | {

Customise search form in the Widget
I would like to customise the Search Form that you drag and drop from the widgets panel.
The customisation will be more than just css changes. I would like to add and custom classes. Is this possible?
Is there a hook to customise the Search Field?
The only option I can think of is to create a custom search widget. | if your theme have not `search-form.php` file then you will create the file and add the custom css there. Because search widget is calling the **get_search_form()** function. First it will search the `search-from.php` file from activated theme folder. If there have no file then it will call wp's default search form.

What's the best approach to do this?
I want to start a new site where I want the main page to be a static page showing information about myself, a kind of resumee without personal details.
Then, there would be a `site.com/blog/` where I occasionally write to demonstrate the skills listed on the static page.
Finally, I want all of this to be in English and Spanish.
* * *
So far, I changed the static front page to "About me" and then I created a new empty page "Blog", and chose it as posts page. When I click on "Blog", I get to the posts page but the URL looks like `/?page_id=11`. I would like it to look as I said before (`/blog/`).
About the language, I see there are multiple plugins that translate the content. I'm interested in write it by myself, and the only plugin that seems to allow this is qTranslate, which doesn't work with the latest WP version. The only idea that comes to my mind is to do two separate installations on `site.com/en` and `site.com/es`. What else could I do? | about the permalinks you should go to settings->permalinks and change permalinks to "post name". then you can see "/blog/" for your blog page. for translating your theme you dont need any plugins. you should work with .po files. go to your theme folder and then "languages". there you can see translation files inside this folder. you can create your own translation files but actually you need a software like "poedit". it's free to download and use. good luck | stackexchange-wordpress | {

Show only first children level of current category?

How to show only first level of children (if exist) on category page? | You are using get_categories() function and this function have not ' **depth** ' argument. Also php is not supporting `$cat-id` variable. it would be `$cat_id`.

WordPress 4.0 beta - how to change the link URL in RSS feeds

Get latest post from all categories except one

while($i<count($output_categories)):
$latest_cat_post_6 =
new WP_Query( array('posts_per_page' => 1,'category__in'=>$output_categories[$i]));
if($latest_cat_post_6 == 48){

} else {
if( $latest_cat_post_6->have_posts() ) :
while( $latest_cat_post_6->have_posts() ) : $latest_cat_post_6->the_post();
}
?> | Your code doesn't make sense to me. The easiest way to do this is to use `get_categories()` to get all the categories, and use the **`exclude` parameter to exclude the category that you don't need**. You can then feed that back into a new `WP_QUERY`
Example
$categories = get_categories( 'exclude=ID_OF_CATEGORY')
foreach ($categories as $category) {
$new_query = new WP_Query( 'posts_per_page=1&cat=' . $category->cat_ID );
if($new_query->have_posts()) :

Missing argument 2 for wpdb::prepare() Issue

Overide enqueue in non plugable function via child theme

The 3rd parameter in remove_action() is the priority. Try playing around with that number - the default is 10 - to see if there is any change.
remove_action() also returns a boolean so you can debug it with
var_dump( remove_action('wp_print_styles', 'az_enqueue_dynamic_css') );

How to query WP Multisite primary site link
Currently I have created a multisite for my client. Within the network, there are a (primary)corporate site, a newsbites site and a blog site. Is there a way to query the primary site link, so that newsbites and blog site can connect back to the (primary) corporate site, without hard coding the site url? | Use `network_home_url( $path = '', $scheme = null )`.

Examples:
// Root of main site
$network_home = network_home_url();
// About page on main site
$network_about = network_home_url( 'about/' );
In a network, the main site has always the same ID as the network ID. `network_home_url()` uses `get_current_site()` which return the global variable (sigh) `$current_site`, an instance of `stdClass`. This one is filled in `wp-includes/ms-settings.php`, which in turn is loaded in `wp-settings.php` **before** mu-plugins are loaded.

I don't want to remove the sidebar completely, but nothing I do in the CSS file allows me to get rid of the black bar. Even removing the sidebar from a template file leaves an empty black strip where the sidebar used to be.
Has anyone found a way to peacefully override this without throwing out the whole system? | The sidebar is created in two different places:
* The black strip is created from `.site:before`, check line 3910 of style.css
* `#secondary` actually displays the sidebar information, check line 3923 of style.css
`.featured-content, .site-content, .site-main .widecolumn` provide left padding to the content area should you wish to dispose of that too. | stackexchange-wordpress | {

Custom Menu url is Empty
I added a new menu using this code:
wp_update_nav_menu_item($menu->term_id, 0, array(
'menu-item-title' => 'Custom menu',
'menu-item-url' => '
'menu-item-db-id' => 0,
'menu-item-object' => 'custom',
'menu-item-parent-id' => 328,
'menu-item-type' => 'Custom',
'menu-item-status' => 'publish',)
);
That code generates a menu the way I wanted. But the link is totally empty. What did I do wrong? | Your menu type is:
'menu-item-type' => 'Custom',
But if we look in `wp_update_nav_menu_item`:
if ( 'custom' != $args['menu-item-type'] ) {
`custom != Custom`, so your URL gets stripped | stackexchange-wordpress | {

Set default link type to "file" for image galleries
Whenever you add a image gallery to a post, the images automatically link to the image attachment pages. This is not ideal, because I want to use Fancybox so the user can cycle through the images.
I tried the following code to let the images link to the files by default, but this doesn't seem to work for galleries. Any suggestions on how to set the default link type to "file" for image galleries?
I would be even happier if the image attachment page wouldn't be available at all (on galleries an regular images). I don't really like this feature.
/**
* Set default image link type to file
*/
function tp_set_default_link_type() {
update_option( 'image_default_link_type', 'file' );
}
add_action( 'after_switch_theme', 'tp_set_default_link_type' );
Thanks in advance! | You can override the gallery shortcode `link` attribute with:
add_filter( 'shortcode_atts_gallery',
function( $out ){
$out['link'] = 'file';
return $out;
}
);
This means that even if your shortcodes are:
[gallery ids="1,2,3"]
[gallery ids="1,2,3" link="none"]
the gallery output will always be generated as if you used `link="file"`. | stackexchange-wordpress | {

Sorting posts by Multiple custom fields in defined order
I'm currently sorting some posts out by custom fields 'role' and 'surname', using the following:
function customorder($orderby) {
return 'mt1.meta_value DESC, mt2.meta_value ASC';
}
$args = array(
'post_type' => 'staff',
'meta_key' => 'role',
'meta_query' => array(

'key' => 'role'

array(
'key' => 'surname',
),
)
);
add_filter('posts_orderby','customorder');
$query = new WP_Query( $args );
remove_filter('posts_orderby','customorder');
How can I define the order that I would like the first meta_key in, as opposed to alphabetically desc or ascending. For example where role = 'Head Teacher', 'Deputy', 'Teacher', 'Support', 'Clerical' ... etc Therefor grouping the posts by the meta_key value.
Thanks in advance for any help
Cheers
Noel | You can use FIELD or FIND_IN_SET:

Disable Debug Log Programmatically
I'm trying to disable `WP_DEBUG_LOG` if and only if `debug.log` exists. I'd like to hook into `wp_footer` and test if the file exists and if so disable my debug log. All I've found though is that `WP_DEBUG_LOG` is a constant and can only be changed from the `wp-config.php` file which is too early for my case. Is there a way to change it from a constant on install and keep it working as normal?
My only other thought is to create an option on install in the options table and just check it every time `wp-config` loaded to see if the value has changed but I was wanting to avoid that.
Granted I could check if the file exists before I define `WP_DEBUG_LOG` but somebody would have to view a page twice before debug log actually exists and is detected by the `file_exists()` (since it's run very early) which is not optimal.
Does anybody know of a workaround to programmatically turn off `WP_DEBUG_LOG`? | @Wyck was right, ( well sorta :P ) you can set error logs but
1) You need to enable debugging
2) `ini_set('log_errors', 1);` or 0 for `false`
3) You need to set a log location via `ini_set('error_log, $location)`
Once you have that set you can then if need be test if said file exists via `$location` and turn off `log_errors` by setting its value to 0. | stackexchange-wordpress | {

Display current category without an active link in wp_list_categories

Subdomains to pages
Hi I have a website on wordpress which have 2 pages which I meant to convert it to subdomain.

RewriteCond %{HTTP_HOST} ^subsite\.domain\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/subsite [NC]
RewriteRule ^(.*)$ /subsite/$1 [L]

Deploying Wordpress for clients - what do they have access to?
I've developed websites from scratch up till now and would like to switch to using Wordpress to save time and money.
I've done some theme customization and plugin work so far. I can see that users can update posts and customize themes themselves from `/wp-admin`.
What I'm concerned about it - is that how projects are generally deployed in wordpress? That the client has access to customize pretty much everything themselves? Do they really get to see all this?
!enter image description here
I've generally made custom CMSs for clients based on whatever their website was, but somehow I feel like this is a bit much for clients to have access to? Or is it normal? | There is also a plugin named Adminize that will allow you to completely customize what the client can see in the admin.

Fluid Featured Post Carousel Slider for Wordpress with no Javascript

Output categories in something different than a list
I wanted to output all my categories in the sidebar of my wordpress theme. Now I use the function `wp_list_categories();` which works fine. However it always displays the categories in a list and I don't want that.
What I want is to display the categories as links so that they are inline elements. I could stay with the list and just style them as inline elements by applying `display: inline-block;` to the list items. I guess it is semantically correct, too.
So is there a way of getting rid of the list in WordPress or should I stay with my approach? And is it semantically correct?

User Tracking for Custom Post Type "Lesson". Database Queries and Performance
So I wrote this little code snippet to add a post id along with the current users id to the user meta table. I'll use this to show the "lesson" posts that a user has viewed back to them.
My only concern with this way of doing it this way is that it seems Wordpress will have to loop through this whole table to retrieve these posts. What if there are tens of thousands of users (I'm being optimistic) and they all view on average 10 or 20 lessons? Could this cause performance issues? I don't know enough about databases yet to know. Is there maybe a better way to go about this that I'm missing?
<?php
if ( is_user_logged_in() ) {
$user_ID = get_current_user_id();
$post_ID = get_the_ID();
add_user_meta( $user_ID, 'viewed_lesson_tracking', $post_ID ); // tracks that user has viewed the current post
}
?>
Thanks for your help! | Since there are going to be more than one post (lesson) per user, your code would be more like this:
<?php
if ( is_user_logged_in() ) {
$user_ID = get_current_user_id();
$post_ID = get_the_ID();
$viewed = get_user_meta( $user_ID, 'viewed_lesson_tracking', true);
if(empty($viewed)){
$viewed = array();
}
$viewed[] = $post_ID
add_user_meta( $user_ID, 'viewed_lesson_tracking', $viewed ); // tracks that user has viewed the current post
}
?>
So, all you have to do, when showing a list of all viewed lessons(posts) is to use the post__in parameter of WP_Query.
WordPress will not loop through the whole table. That's not how MySQL queries work. At any given time, there'll only be one query per user. You won't need to worry about the performance. Plus, WordPress caches all the queries and if you have a cache plugin on top of it, you don't need to even give it a thought. | stackexchange-wordpress | {

}
$loop = new WP_Query($query_params);
if($loop->have_posts()) : while($loop->have_posts()): $loop->the_post();
// SOME HTML

$categories = get_categories("taxonomy=city");
foreach ($categories as $category) :
echo '<li>' . $category->name . '</li>';

Is it possible to override this function/class in a child theme?
Is it possible to override this `widget` function from a parent theme? I saw this blog, but it dealt with a simpler case.

class Chocolat_Widget_New_Entrys extends WP_Widget {
function __construct() {...
function widget( $args, $instance ) {...
}

I attempted to use `remove_action('widgets_init','???');` but soon realized I could not get a handle on the function that registered it!
I thought about overriding the function and creating a subclass, but still, it is registered in the parent by the name of the parent class.
I thought about just copying the whole class, but child `functions.php` is loaded before `parents.php`. | You simply need to run your code on a higher priority than what the parent theme is, the default on `add_action` function is 10 so you can use:
function s157343_unregister_widgets() {
unregister_widget( 'Chocolat_Widget_New_Entrys' );
}
add_action( 'widgets_init', 's157343_unregister_widgets', 20 );
This will unregister that widget. Of course, you can still create a new class that extends that widget's class to override the methods you want and register a new widget based on that:
class my_Chocolat_Widget_New_Entrys extends Chocolat_Widget_New_Entrys() {
public function __construct() {}
public function widget( $args, $instance ) {}

How to do that? | As Tom said, that will never work, as the main query have already executed. The only way to achieve that is to alter the main query **before** it is executed.

function wpse_custom_ppp( $query ) {
if ( !is_admin() && $query->is_main_query() ) {
$query->set( 'posts_per_page', '1000' );

Firstly, you are enqueueing your style with `wp_enqueue_script()`, which is meant to be used by scripts. You should be using `wp_enqueue_style`
Secondly, you need to understand what functions are loaded when. Plugins are loaded first, child themes second and parent themes last. So you styles gets loaded first, and then the styles of the theme. This means, duplicate css selectors get overwritten by the theme styles.
To make sure that your plugin style gets loaded after the theme's style, just add priority to your action. For reference, see `add_action( $hook, $function_to_add, $priority, $accepted_args )`. Be sure to use a very low priority (very high number)
Your code should be
/**
* Enqueue plugin style-file

</p>
<?php
}
Is using `is_email()` correct for this? Thank-you! | According to the documentation, is_email() is used to validate an email and either returns the email if it is valid or false if it isn't. So are using it correctly.
The only thing I can see in your code is that if the email is not valid, you are settings the data to a boolean value of FALSE.
$instance['email'] = is_email($new_instance['email']);
//with a bad email address, this will be the same as writing
$instance['email'] = false;
Depending on what you're doing in the widget that may give you unexpected results.
I would instead do something like the following
$instance['email'] = ( is_email($new_instance['email']) ) ? $new_instance['email'] : '';
This is going to make sure that if the is_email() call returns false then you are setting $instance['email'] to an empty string instead of a boolean value.

Display what taxonomies a custom post has?
I've trying to search high and low for this but am having a really hard time.
Essentially, I have a custom post type called `locations` with taxonomies. The posts in "locations" are categorized under several taxonomies called `markets`, `products`, `size`, `country`, etc."
I just need to know how I can get it so my custom post type on the front end displays what taxonomies the post is categorized into. Does anyone know how I can do that?
To clarify, I just basically need to emulate this page to a tee (which is a drupal site) where you can see what categories the post if under.

Would greatly appreciate ANY guidance or feedback. | As there's multiple Taxonomies, you will need to loop through all of the assigned taxonomies of that post type. `get_object_taxonomies` is the function which returns array of post type taxonomies.

Database Name Change
I read it was more secure to use something else besides wp_ as the database prefix, so I downloaded my .sql file replaced all instances of wp_ with tsi_ and then dropped the wp_ tables and imported my .sql file.
The prefix is now correct, so then I went to my wp_config file and changed the prefix table from wp_ to tsi_ and I thought everything was good.
Well, all my posts were still there, but the images are missing. I say missing because when you look in the uploads folder they are there, correctly sorted and everything, but in the media library, they appear as grey icons instead of the previews and they are missing from all my posts. Is there any way to get the images to display correctly?
*The domain name did not change or any of my settings, I just changed the database prefix and that's it.
The grey icons in the media library:
!enter image description here
The posts without images:

Thanks,
Josh | Ok...
So after some more research I found: < which explains that you can't just do a find and replace in a text editor and be good to go.
Fortunately, I still had the original database, so I dropped all the tables in the tsi_ database and restored the original wp_ database.
All my images were restored and the site was back to normal, now to change the database prefix properly...
I found a plugin called Change DB Prefix: < it allows you to put in the old prefix wp_ and replace it with a new one tsi_.
The plugin safely changed my database prefix and updated my wp_config file in less than a second! All my images are fine and everything is now up and running correctly with the new database prefix!!
Hope this helps someone!

Add_query_arg + two times the same argument?
I'am trying to filter my archive page by clicking links. When clicked they execute the add_query_arg command.
Everything works fine so far.
But now i want to add combinations within the same custom taxonomy.
ex: < '?events=test&events=test2'
now the question, how to add two times the same argument with add_query_arg without overwriting the first one ? And how to get them again ?
Hope someone can help me out here.

Adding Read More to Custom excerpts

global $post;
return '<strong><a class="moretag" href="'. get_permalink($post->ID) . '">... Read More</a></strong>';

However I would also like this to appear when something has been specified in this box, currently it only displays in the first instance.

$post_cats = get_the_category();
return '<p>This post is in the ' . $post_cats[0]->cat_name . ' category</p>' . $content;

Add management screens to post type

* View Memberships
* Add Membership
* Options

add_action( 'admin_menu', 'register_my_custom_menu_page' );
function register_my_custom_menu_page(){
add_menu_page('My Custom Page', 'My Custom Page', 'manage_options', 'my-top-level-slug', '', '', 28);

How to obtain the current website URL in my theme?

After updating WP keeps nagging about a newer version. Why?
I updated WP to version 3.9.2 (currently the latest) via Git which works fine. However, in the admin it keeps on telling me “a newer version is available”. After some digging somehow it appears to be related to the language pack. I’ve got `WPLANG` set to `nl_NL`.

Click it and you’ll notice it offers a response with the status “upgrade”, yet the version is the same!? If you remove locale argument at the end or leave it empty (URL below), you’ll see it will answer with a status value of “latest” and thus not triggering update nags.

Why I can't change the permalink of this page?
I have the following problem with a permalink: if I open this page (it is implemented as a static page) on my local website: `localhost/wordpressAsper/archivio` it automatically change it into `

For example the **function.php** file ino every theme is not a class but is a simple php file containing some functions, so it respect the old procedural model.
At the same time it seems to me that WP don't use MVC pattern
My question is: why WordPress (that is a modern CMS) don't use a totally Object Oriented paradigm and don't adopt the MVC model? | WordPress as a project has extreme commitment to backwards compatibility. Whatever new things you add the old things need to work still. Whatever things you change still need to work in old _way_ as well.
So regardless of how WP started as non–MVC application, it cannot become one without retaining all of its non–MVC ways. Which makes it pretty pointless direction.
Coming from formal background MVC might seem like a baseline and "naturally" preferable way to organize. Coming from self–taught background (or lack of programming background entirely) it's mostly overblown abstraction which even people who like it cannot agree on.
WordPress largely targets _users_ , not _developers_. Any complicating of the learning curve will just be shooting its strong sides for little gain. | stackexchange-wordpress | {

Custom MySQL Query for Post and Post Meta
I have a custom table called "tags" that contains a `charity_id` that is a reference to a post ID ... I need to query the "tags" table to grab this `charity_id` and then pull in the post title and a few of the meta data.
Ideally, the end result would produce the following:
tags.serial_number, post.title, post_meta_data.post_title, post_meta_data.location_city, post_meta_data.location_state, post_meta_data.location_country | You have to use `JOIN` for that. Try it like this:
$wpdb->get_results("SELECT tags.*, $wpdb->posts.*, $wpdb->postmeta.*
FROM tags
INNER JOIN $wpdb->posts ON tags.charity_id = $wpdb->posts.ID
INNER JOIN $wpdb->postmeta ON tags.charity_id = $wpdb->postmeta.post_id

Get multiple tags by slug
The following code works fine for me:
$term = get_term_by('slug', ‘foo’, 'post_tag');
$args = array (
'posts_per_page' => 5,
'paged' => $paged,
'post__not_in' => get_option( 'sticky_posts' ) ,
'tag__not_in' => $term
);
I'd now like to `get_term_by` multiple tags, e.g., 'foo' and 'bar' (I'm trying to display all posts _except_ those tagged 'foo' or 'bar').
I realize this is probably elementary, but I'm not sure how to go about it.
Ideas? | I've come up with a better way than in my previous answer:
First you need to set up an array containing the slugs of the tags you want to exclude. Then loop over that array, and on each term, use `get_term_by()` to get the tag, saving its ID to another array. That is what you can pass through to your query.
$tag_slugs = array(
'foo',
'bar',
);
$tag_ids = array();
foreach( $tag_slugs as $slug ) {
$tag = get_term_by( 'slug', $slug, 'post_tag' );
$tag_ids[] = $tag->term_id;
}
$args = array (
'posts_per_page' => 5,
'paged' => $paged,
'post__not_in' => get_option( 'sticky_posts' ),
'tag__not_in' => $tag_ids,

Can I use $wpdb for my custom tables in the WordPress database?
I am building a custom application based on WordPress. I have my custom tables in the WP database. Can I use $wpdb to work with them, or is that class solely for the WP related tables?
For example, If I have a database that keeps up with dogs and cats, and I create a custom table named animals (animalid, animal_type, etc.). Do I use $wpdb?
I don't know if "interacting with the WordPress database" with $wpdb is intended solely for the stock tables or not.

Page that links to category content
I have a page called: fruit...then I have three child pages called cherry, lemon, and peach. I also have a category called fruit, and three child categories called cherry, lemon, and peach. What I am trying to do is when a user clicks on one of the child pages IE: "Cherry" the user gets a category page with all posts associated to the "Cherry" category.
Normally this wouldn't be a big deal, I'd manually do an `<?php if (is_page("cherry")) { ?>` in my template, but what I'm looking for is a way to do it dynamically so that if someone creates a new child page and a matching child category then everything will be good to go without having to manually adjust the template.
I guess it would be taking the page and redirecting to it's corresponding category page, but is that possible?
Thanks,
Josh | You can do something like this
global $post;
//Get the page name
$term = get_post( $post )->post_name;
//If a category with the same name exists, then show the posts from that category
if( term_exists( $term, 'category') )
{
//Show posts from $term category

Grab values from the query string to fill in hidden fields in ninja forms
I've added a custom page template where I pull out a list of available jobs from the database.
The page displaying the jobs is called `jobs`.
I'm using the `Ninja forms` plugin to add a form on a page called `apply.php`, which has fields for a job application.
Now for each job title offered on the jobs page, I want it to be a link that the user can click on to apply, and be redirected to `apply.php`, where I can grab the job id and save in a hidden field on `apply.php`.
This is so that when I save the applicant's submission, I can get it saved together with the job they applied to.
I've added the link alright - as follows:
?page_id=18&jid=2
where 18 is the id of the apply page, the page that I've got the ninja form on.
But how can I grab the jid from the query string and use it in the ninja form fields? | @Eric Allen's answer worked perfectly.

How to add images to taxonomies?
**Q:** Is it possible to add images to all of my taxonomies (default and custom ones)?
**Note:** I do not want to use any plugins (not my favourite solution for design related matters).
**Usage:** I want to create really practical custom post type portfolio with custom taxonomies. For example, custom taxonomy - clients, so if multiple projects from same customer/client would be realted and at the same time I could use the taxonomy as showcase of my clients. The similar usage would go with almost of my taxonomies (whether to have taxonomy archive with image and description on).
Any good practice advice here? Thanks in advance
**Clarification:** I want to add images to the terms of my custom taxonomies. Example, custom post type 'portfolio' with custom taxonomy 'clients', where each 'client' term (lets say Adidas) would have its logo attached. | Starting from Wordpress 4.4, you can use add_term_meta function to store metadata for a term. This is basically a key-value pair information which is stored in `wp_termmeta` table.
**Original Answer(Prior to WP 4.4)**
Wordpress doesn't have the option to add extra information to taxonomies. There isn't any `taxonomy_meta` table. So, you have two options.
* Create a new custom table and save the extra information(image link) there.
* You can also use `options` table to store the information.

How to add a rel attribute to images that contains their categories?

/**
* Create a rel attribute from the image categories
*

function( $html, $id )

}
return str_ireplace(
'<img ',
sprintf( '<img rel="%s" ', join( ' ', $rel ) ),
$html
);
}
, 10, 2 );
where we use the `get_image_tag` filter to modify the inserted image HTML.

Tags such as `<div>` or `<pre>` are still available when commenting. | There's a filter-hook that allows you to run some checking before comment is posted so you could use it too :
add_filter('preprocess_comment', 'wpse_158147_check_new_comment');
function wpse_158147_check_new_comment($commentdata){
$commentdata['comment_content'] = preg_replace("/<tag(.*?)>(.*)<\/tag>/", "$2", $commentdata['comment_content']);// or str_replace
return $commentdata;
}
Here "tag" would be stripped (to be replaced here with your specific tag). | stackexchange-wordpress | {
