Accepted arguments value in hook functions
Let's say I have the following hook function:
function my_function() {
$post_type = isset( $_GET['post_type'] ) ? $_GET['post_type'] : '';
if( !isset( $_REQUEST['mode'] ) )
$_REQUEST['mode'] = ( $post_type == 'my_post_type' ) ? 'excerpt' : 'list';
}
`add_action( 'load-edit.php', 'my_function', 10, 1 );`
The fourth argument is (from WP Codex):
> (int) (optional) The number of arguments the hooked function accepts. In WordPress 1.5.1+, hooked functions can take extra arguments that are set when the matching do_action() or apply_filters() call is run. For example, the action comment_id_not_found will pass any functions that hook onto it the ID of the requested comment.
>
>
> Default: 1
>
The default value is 1, however I do not pass any arguments to the hook function.
Should I add an action like that?
`add_action( 'load-edit.php', 'my_function', 10, 0 );` | The accepted arguments value is used by WordPress as `$length` argument for `array_slice` when performing the action.
It means that, yes, if you pass `0` no argument will be passed to your callback.
However, you should care of that only if your function acts differently if an argument is passed or not.
A function like the one in OP, is defined without any argument, nor any function like `func_get_args()` or `func_get_arg()` is used in it, so it means that **you can pass any number of arguments to that function, but it will not change its behaviour**.
For that reason you can just ignore the 4th argument of `add_action` like so:
add_action( 'load-edit.php', 'my_function', 10 );
also consider that 10 is default priority, so previous line has same effect of
add_action( 'load-edit.php', 'my_function' );
It's not worse nor better from a code quality point of view, avoid to pass irrelevant arguments just saves you to type some chars. | stackexchange-wordpress | {

how to make a new page affected by a theme's index.php layout?
I need to create some new pages for my website e.g. Gallery, Audio collection, etc. I want them to have a layout similar to my theme's index.php. How can I do this so that the layout updates for the mentioned pages if I change current theme for my WordPress website?
Do I have to use the same markup of index.php in new pages I want to create or is there a systematic way to tell WordPress to use the same layout for my theme's index.php for my new pages? | Wordpress loads templates in order from most specific to least specific, depending on which templates files exists.
For instance, lets say we have a wordpress page by name of "Audio Collection" with page ID of 14. WordPress would look for files by these names in order, and return the template for the first file name it checks that exists in your active theme.
* page-audio-collection.php
* page-14.php
* page.php
* index.php
So if you wanted to, you could create a duplicate of index.php, and call it page-audio-collection.php, and modify it as needed. That template would only be loaded when viewing the Audio Collection page, and all other pages would continue loading their current template file.
You could also create and assign a Custom Page Template, which would override all of the normal template hierarchy I outlined above.

I want to rel=nofollow wordpress images
I have a default theme. When i add media to wordpress site. By default it use simple "a href" tag I want to add attribute "rel=nofollow" to it. Can anybody please point me in right direction?. | You need to hook into the image_send_to_editor filter. This allows you to modify the markup used when inserting an image into the content editor.
Something like this should work:

function my_add_rel_nofollow($html, $id, $caption, $title, $align, $url, $size, $alt = '' ){

} else {
$html = preg_replace('/(<a.*?)>/', '$1 rel="' . 'nofollow' . '" >', $html);
}
return $html;
}
This will first check if there is already a `rel` attribute, and add the no_follow. Or, if there is no `rel` attribute, it will add one, and set it to `nofollow`. | stackexchange-wordpress | {

How to hide page links from theme menu

My guess is you will need a combination of body class (for the correct content type), media query and appropriate CSS. | stackexchange-wordpress | {

I'm assuming you mean that this query gives you all posts inside _post type_ inspiration and you want to pull specific post IDs instead of all _posts_ of the _post type_. Taxonomies and Post Types. are two different things.
Try to alter your query to something like this:
$loop = new WP_Query( array(
'post_type' => 'inspirations',
'post__in' => array( 4174, 3608 )
));
The difference between this and your original loop is that 1) There is a post type defined and 2) `post__in` has 2 underscore where yours has 1. I removed the `posts_per_page` parameter as this query should only return 2 posts. | stackexchange-wordpress | {

Post Type Upload Directory - {post_type}_upload_dir filter
I'm working with modifying the upload directory depending on which post type is being uploaded to. I've ran across this question: Post type specific upload folder in 3.5 and one of the lines confused me:

Where `$type` is the post type. They then go on to join the paths:
$dir['path'] = path_join($dir['basedir'], $uploads);
$dir['url'] = path_join($dir['baseurl'], $uploads);
Which works fine, you get the expected upload folder of `wp-content/uploads/post-type-name` but what does the `apply_filtes` achieve? It seems like I could just change that line to:
`$uploads = $type` or `$dir['path'] = path_join($dir['basedir'], $type);`
and I will still get the same folder structure, so what does the `apply_fitlers` portion actually achieve? I can't seem to find reference on the filter anywhere either. | 'apply_filters' runs the value through all of the other hooks / functions attached to it. Try an experiment:
print_r( $type );

This will display all posts in the query, which in a taxonomy template will be all posts attached to a term.

How to redirect correctly a root domain to a subdomain in a subfolder?
The next `.htaccess` code redirects `example.com` (from _/public_html_ root folder) to the `subdomain1.example.com` (to _/public_html/subdomain1_ subdolder) and an old page _register_ to a new one at `subdomain1.example.com/enroll`. So far so good! But, I have also a subdomain `subdomain2.example.com` (in the _/public_html/subdomain2_ subfolder) that instead of his normal URL is redirected to the `subdomain1.example.com/subfolder2`, that not exists.

Restricting page access
I need to restrict access to a page in a wordpress site for everyone but registered users. I have looked at a couple of plugins, and although they work well, they don't quite fit my solution... The page I am trying to restrict is based on a page template that itself has some hard coded forms that will interact with a backend server. The plugins I have tried block the WP content, but I can still see the forms from the template.
I need:
1. show login and registration box in-line on the blocked page that I can style (not redirect to standard WP logon)
2. upon successful registration, then the page will show the content including the template content. I hope this is clear and that someone can help me with either a better plugin, or a code solution.

List of users with email and role

// Array of WP_User objects.

background_image support multiple image size?
Does background_image support showing multiple image sizes like feature image? I can see multiple files were created when I uploaded a file. How do I use those images or does background_image not allow that to happen?
Something like `get_background_image('large')` [doesn't work] or something where I can insert the dimensions after the file name like the-url-to-the-image-1024x768.jpg. | Figured it out using `str_replace`.
First the location of the background image is stored in a string:
<?php $backimg = get_background_image(); ?>
Then perform a string and replace where the `.jpg` is removed at the end of the `$backimg` and is stored as `$bgraw`
<?php $bgraw = str_replace('.jpg','',$backimg);?>
It output as:
The .jpg is removed; from there you insert the file you want to use. For example, I have a custom image where the dimensions are 1280px wide by 450px height. The image is created as fileimage.jpg-1280x450.jpg.
To use that image, take the stored value of `$bgraw` and add `-1280x450.jpg` or whatever file you want to use instead.
<?php echo $bgraw . '-1280x450.jpg' ;?>

How-to stop wordpress from saving utf8 non-breaking space characters
Anyone have a tip on how to prevent Wordpress from saving utf8 space characters (= hex C2 A0) in DB by replacing with space \x20 ?
Is there a hook that can be used to do a replace before saving to tables?
Background: ` ` looks like any other "space" character to the eye in editors (Notepad, Notepad++, Wordpress etc.) but actually hides itself in 2-byte code (`\xc2\xa0`) if you view though a hex editor.
Problem: css word-wrap causes sentence not to wrap as they should as it knows it's a "non-breaking space".
User experience: When someone does copy+paste from another source (website, word document etc.) sometimes the original space is a ` ` and the user doesn't see or know this as they're not that tech focused as we are.
Anyone has an idea or proposal for solution here?
Thx | Both initial creation and updates for the posts pass through `wp_insert_post_data` (among other filters). You can modify `post_content` item in array passed to make the replacement you need, before it proceeds on to be saved in database.
**Update** Code pasted from comments
add_filter( 'wp_insert_post_data', 'rm_wp_insert_post_data', '99', 2 );
function rm_wp_insert_post_data ( $data , $postarr ) {

Is it risky if I update all url in the database due to my site url changed?
Let's say I have a wordpress site on a subdomain.
Initially, I created the site with "www." >>> www.mysite.mainsite.com
Now, I'd like to change site url to only mysite.mainsite.com without www anymore.
I can change it via Settting > General but I checked the database and I found that all of my images in media library (guid field of the posts table) are still having www.mysite.mainsite.com with www which I don't want it anymore.
I also found this thread related to this Changing www prefix in General Settings and Interior Links
But anyone can suggest if it's risky to do that or not? Will the code there usable for today?
Thanks | I have updated the URLs stored in the database when the domain has changed.
Here are the things to watch for:
1. In the `posts` table, the post_content will have any embedded links. These you can change without issue.
2. Again in the `posts` table, the gid would change if you do a global search and replace. This is mostly used with regard to RSS feeds. You can either change them or leave them without much issue unless the RSS GID is important to you.
3. In the `postmeta` table, this is where it gets tricky. If the field is just a raw string field, then you'll have no issue changing it. **The issue is when the URL is within serialized PHP data.**
**Why serialized data would break**
When PHP serializes a string, it embeds the length of the string. For example, ` becomes `s:22:" Notice the `22` after `s:`, this is the string length. If we drop the `www`, then the serialized value would be: `s:18:" If the length is wrong, then the data becomes garbage to WordPress. | stackexchange-wordpress | {

Remove function or filter
Im working with a child-theme of Wordpress-Bootstrap by 320press.com I want to get rid of the lead class added to the first paragraph of the content.
I looked in Wordpress codex in these articles:
* `remove_action`
* `remove_filter`
But im not so experienced in PHP, only HTML - so i cant really tell if its a filter or a function that i need to remove - i tried both solutions in above links, but i cant seem to get any of them to work.
This is the PHP from functions.php that adds the class
// Add lead class to first paragraph
function first_paragraph( $content ){
global $post;
// if we're on the homepage, don't add the lead class to the first paragraph of text
if( is_page_template( 'page-homepage.php' ) )
return $content;
else
return preg_replace('/<p([^>]+)?>/', '<p$1 class="lead">', $content, 1);
}
add_filter( 'the_content', 'first_paragraph' ); | Your problem isn't that you did the wrong thing, it's that you did it at the wrong time. When it happens is important, not where.
In a child theme, the functions.php is loaded, then the parents, so you're doing this:
1. Remove the `first_paragraph` function from `the_content` filter
2. Add the `first_paragraph` function to `the_content` filter
Clearly this is the wrong way round. It's like building the penthouse of a skyscraper first then building the foundations second, it isn't going to work. Here you can't remove the filter because it hasn't been added yet
To get around this, remove the filter at a later point using an action/hook, e.g.:
// when the init hook fires
add_action( 'init', 'sillo_remove_that_filter' );
function sillo_remove_that_filter() {
// remove the filter

Multiple instance of data in plugin custom database table on plugin activation

Making the columns type is not an UNIQUE.
**My question** How do i prevent the plugin from inserting the same data that was meant to be inserted int the database just once on plugin activation? | Found a great solution.
Basically, you can check if an option name exists and if it already exists you don't insert your data.
The main idea is, each time your database schema changes and requires an update on your user’s database, you need to increment the DB_VER by 1, then write a database upgrade routine for the current DB_VER. This would create some sort of an evolution trail of your database schema, which is very helpful when your user needs to upgrade from an ancient version to the latest one. WordPress itself keeps track of its schema changes this way, so it’s always safe to upgrade from WordPress 2.x to 3.x without much issue.

Does WordPress support Plupload chunking when uploading asynchronously?

chunk_size : '200kb',
max_retries : 3

My aim is to break files down into smaller 'chunks' whilst uploading. Plupload has built-in support for this.
**My question**
An example of server-side chuck handling is provided by Plupload. Does WordPress handle chunks server-side when uploading asynchronously or is this something I have to do myself?
Ref: < | To the best of my knowledge, no, the async-upload process on the WordPress side does not support chunking from plupload. You can find this code in /wp-admin/async-upload.php.
To handle the uploaded file, it calls the wp_ajax_upload_attachment() function, in the ajax-actions.php file. This function refers directly to the PHP $_FILES array, meaning that the file would be completely uploaded and saved to a tmp file by PHP before WordPress is invoked. Therefore chunking is not directly supported. | stackexchange-wordpress | {

Extract post category except one category
My posts are in two categories - one that defines their type eg. `article` or `review` and the other defines the topic - `tablets`,`smartphones`,`smartwatches`, etc.
How can I get the current post's category ID for its topic - i.e. whether it's a `tablet`, `smartphone` or `smartwatch`.
If I do `get_the_category( $post->ID );` I suppose it'll return all categories the post is in, but how do I filter out the `article` or `review` categories out?
Example: Post `ABC` is in categories `article` with `ID=1` and `tablets` with `ID=10` how can I extract on the `tablets` `ID=10` category without the `article` one? | You can simply loop over the categories that you don't need. `get_the_category()` return an array of categories that the post belongs to.
With that in mind, you can do the following: ( _Just remember to change`21` and `41` to your desired ID's_)
$categories = get_the_category();
foreach ( $categories as $category ) {
if( 21 === $category->cat_ID || 41 === $category->cat_ID ) {

Displaying posts on homepage - Template Page

What is the problem with it? | The template tags (like `the_content()`) aren't available when using `get_posts`. In order to make the template tags available, you have to make use of `setup_postdata( $post );`

setup_postdata( $post );

ReOrder Post Within Categories plugin with featured image
I need to add featured image somewhere near title so I can easier sort them, currently the plugin use this code to show the title only, tried with the_post_thumbnail and nothing is showing up. Thank you.
echo '<li id="'.$post->ID.'">';
echo '<span class="title">'.$post->post_title.'</span>';

$thumb_url = wp_get_attachment_url( get_post_thumbnail_id( $post->ID ) );
echo '<li id="' . $post->ID . '">';
echo '<img src="' . $thumb_url . '" alt="" />';

Using wp_add_inline_style without a stylesheet

Of course, I could add them directly in the header.php file but I'd like to avoid this. | You just need to add the styles directly to the page head. The best way to do this is to use the 'wp_head' action hook, assuming you are using a theme that has the hook. Like so:

function my_custom_styles()
{
echo "<style>*{color: red}</style>";

current user can edit user?

because in Wordpress documentation a did not see this capability | Yes it can be good practice to check if a user is capable of doing something before doing something related in code.
For example, don't save a custom post type if the user doesn't have the capabilities needed to do it, or don't show certain things to users who don't have the `manage_options` capability ( super admins and admins normally ).
Bad practice in this case would be assuming the user has the necessary role to do these things and doing them anyway.

I am deploying WordPress MultiSite and if I get a decent amount of users, I will have thousands of database tables to support all of these sites. I like the idea of consolidating all of these tables to a single set of tables to make multisite more manageable and also more optimized for SQL Server. Has anyone had experience with a large number of tables issue in multisite?
**Edit:** Basically I want to understand the performance impact of having thousands of tables added over time? | Well, WordPress.com it's the largest deployment of WordPress Multisite and they're basically using the same setup (multiple tables for each site), so you could say that it's a good strategy.
This kind of setup would let you to, for instance, keep your VIP users on a dedicated box, or add multiple DB servers as the network grows.
I've had experience with networks of about 500 sites and some basic tuning it's enough to keep the sites working.
Also, check the HyperDB plugin, which it's a replacement for WordPress' default DB class that "supports replication, failover, load balancing, and partitioning" | stackexchange-wordpress | {

Why isn't the login page rate limited by default?
Brute force attacks seem to the be most common vulnerability on WP installs and rate limiting ought to be relatively easy to bake into WP itself as part of the official, default software (without the need to install a plugin). Why isn't this basic security feature included by default? | > Brute force attacks seem to the be most common vulnerability on WP installs
1. Brute force attacks are not WordPress vulnerability. They are password vulnerability, if bad passwords are used.
2. They are common, but if they are "the most common" in occurrences and, more importantly, breaches is questionable.
> rate limiting ought to be relatively easy to bake into WP itself
Had you _tried_ to bake this _easy_ thing? :)
I am yet to see login "security" plugin that didn't cause login issues long term, clashed with less than mainstream browsers, clashed with password manager applications, and so on. Ok, maybe there is one I can think of — for Google 2FA.
Anyone yet to demonstrate that _easy_ thing can be done reliably in plugin. Doing it at core scale? Ugh.
> Why isn't this basic security feature included by default?

My homepage's width has reduced and I can´t fix it
I am creating a site for a friend of mine and I'm having trouble with the width of my homepage.
The homepage is set as a full width page but when you view it it only displays about 60% of the span. Before attempting to do this on my friend's server and domain, I used a domain of myown to show him a model and the model works just fine.
Here is the homepage Here is the model
I made another full widh page just to see if it wasn't the template, but that test page is OK (I wanted to show you the link but I'm not allowed)
I thought that maybe a plugin that I'm using (Widgetize pages Light) might be causing the problem, so I deactivated it for a while but the problem persists. Anyway, the same plugin is in use on the test site.
What coul be the problem? Please give me a hand.
Thank you in advance.

Delete tables from database when deleting plugin

Adding text in more than one language (at the same time)

There are alternate approaches to configuration, such as loading credentials via environment variables, but in practice they are used exceedingly rarely because PHP's configuration file is a reasonable solution already.
It's not clear why you assume someone will get access to the configuration file. As a low-hanging fruit, you can place it outside of the web accessible directory. WordPress will scan for the configuration file up one directory level above itself.

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) [R=301,L]
