Front-end only $_POST and $_POST requests handling in WordPress plugin
I just created a WordPress plugin with a custom template that handles a $_GET request before the HTML code. Wordpress team is asking me to put this code inside a function.
I understand that for admin panel forms the way is to use
admin-post.php
or
add_action( 'admin_post_****', '****' );
But how do you handle a front-end form post (not that of admin panel). In what kind of a function should I put my template's $_GET or $_POST handling code. Because wordpress.org is not accepting my plugin without these request handles to be inside a function. | you can use something like this:
add_action( 'admin_post_add_foobar', 'prefix_admin_add_foobar' );
//this next action version allows users not logged in to submit requests
//if you want to have both logged in and not logged in users submitting, you have to add both actions!
add_action( 'admin_post_nopriv_add_foobar', 'prefix_admin_add_foobar' );
function prefix_admin_add_foobar() {
status_header(200);
die("Server received '{$_REQUEST['data']}' from your browser.");
//request handlers should die() when they complete their task
}

parse content from wikipedia article replacing search term with the title of article
I have a piece of php code, which shows wikipedia article introduction. It works fine, but I need to replace search term with the title of article.
<?php
function getDescription($keyword){
$url='
$xml=simplexml_load_file($url);
return $xml->Result->Description;
}
echo getDescription('*some term*');
?>
My problem is to replace `getDescription ('*some term*');` search word with title of article.
I`m trying with:
echo getDescription('<?php single_post_title(); ?>');
but it returns nothing.
My code located on other plugin (advanced ads). Any suggestions?
Thanks | You can't and shouldn't echo something into a function's arguments. The `single_post_title()` function will echo the title by default. You should either set the second parameter to false, or use another function:
echo getDescription( single_post_title( '', false ) );
WordPress also offers the `get_the_title()` function that returns the single post's title which you can use here.
So, your code should be:
echo getDescription( get_the_title() ); | stackexchange-wordpress | {

wordpress with 1.5 million posts
I wanted to transform my dictionaries into a WordPress website that has different dictionaries for different views. As you can imagine by now, the posts will mostly have just 2 words and a short sentence of the definition.
so The post body will mostly be this big:
home / casa
a place when people love
I'm not sure how much space that post would occupy considering it will be linked to 1 category (no tags nothing else) and have an explanatory title like `casa translation`
The text files in total consist in about 100MB of space I'm guessing as WordPress posts they would occupy double that. So I have 1Gb of ram. Will this be enough according to you WP experts out there?
Any possible fine tuning/customization I could make?
Like fcgicache or some mysql cache because I'm thinking WP super cache would not be a good option for so many files.
Thank you! | 1 GB on virtual private server (VPS) should be enough, if you don't have a high traffic.
WP Cache could cause problems when number of posts is more than 30,000 due to limitations on file descriptors.
Main rules of tuning nginx, php and MySQL are the same as for high traffic site. You can read relevant article in my blog. | stackexchange-wordpress | {

Slow Search Queries - How to exclude pages, media, excerpt, authors, private posts?
So I have this from _Query Monitor_ :
AND (((zp_posts.post_title LIKE '%mercedes%')
OR (zp_posts.post_excerpt LIKE '%mercedes%')
OR (zp_posts.post_content LIKE '%mercedes%')))
AND zp_posts.post_type IN ('post', 'page', 'attachment')
AND (zp_posts.post_status = 'publish'
OR zp_posts.post_author = 1
AND zp_posts.post_status = 'private')
ORDER BY zp_posts.post_title LIKE '%mercedes%' DESC, zp_posts.post_date DESC
I would like the searches queries to target only post_title and post_content, exclude all others parts. Any idea in achieving that? | You should be able to use `pre_get_posts` to change the query. I'd suggest creating a custom plugin, so that if you ever change your theme your modifications will still apply.
To get you started, here's how you can set the post types being searched:
function search_filter($query) {
if ( !is_admin() && $query->is_main_query() ) {
if ($query->is_search) {
$query->set('post_type', array( 'post' ) );
}
}
}
add_action('pre_get_posts','search_filter');
You would continue to add `$query->set` statements inside the conditionals to further customize what fields to search.
One other option would be to write a completely custom query and call that from your search rather than using WP's built-in query. You might want to benchmark that solution to see whether it is any faster than the `pre_get_posts` way. | stackexchange-wordpress | {

Can I use register_settings and unregister_setting once the settings page has loaded?
I want to add few settings fields dynamically on settings page depending on user action. I am planning to register these new fields dynamically once user asks for it and show the corresponding HTML using jQuery. Is it possible to register settings once you are already on settings page? Also, is there a better way to do this? | Better to avoid such a thing. The settings API has two "faces", one the UI, and the other is handling the form submission. The form submission is handled on a different URL than the UI (`/wp-admin/options.php`) and therefor your "user action" depended code will not run and the handling of storing the setting in the DB might fail.
You need to register properly all fields, and then you can use CSS or JS to show/hide the relevant UI. | stackexchange-wordpress | {

Override plugin option by with a custom theme
I'm creating a custom theme and using one of video embedding plugins from the market. There are plenty of options and among them "don't load css style", is there a way how to make it always checked when my theme is active? Author hasn't provided any define value to fix it.
it's stored in option: `fve_disable_css`
I have tried to `update_option();` on init and as well tried a filter `pre_option_fve_disable_css` but no success, any ideas?
Thanks a lot | Plugin can read options on init event or just in code (during loading). All plugins are loaded before theme load. So, using init action can be too late.
Filter `pre_option_fve_disable_css` doesn't change value of the option. Instead, you have to use `option_fve_disable_css` filter. But again, it can be also too late.
You should check the handle name in wp_enqueue_script function in plugin code, which enqueues relevant css and deregister this handle in your functions.php during wp_enqueue_script event. This is the right time for such an action. | stackexchange-wordpress | {

Redefine REST API variables
I'm having quite a few problems with my WP settings. The main issue is that I need to have WP installed at //domain1.xxx/ and viewed at //domain2.xxx. It's not enough to change wp_home and wp_site_url to achieve this. Since I want to remove all trace of domain1 when viewing the site at domain2 I use relative paths (courtesy of a plugin called "Remove HTTP"). The problem that remains is that some plugins still use absolute paths. One of them is Contact Form 7 which use the WP REST API. My question is: Can I redefine the REST variables so that I remove domain1 and replace it with preferable "/" or if that fails use domain2. | This solved my problem:
if ( $_SERVER['HTTP_X_FORWARDED_HOST'] ) {
$_SERVER['SERVER_NAME'] = $_SERVER['HTTP_X_FORWARDED_HOST'];
}
$_SERVER['HTTP_HOST'] = $_SERVER['SERVER_NAME'];
define('WP_HOME',' $_SERVER['SERVER_NAME']);
define('WP_SITEURL',' $_SERVER['SERVER_NAME']);

Theme-based character encoding issue

Extract links inside embed tags in WordPress
I am using the default WordPress embed to embed a couple of videos in the content.
I want to extract the video link from `[embed] can anyone help with the regex? | No need to use regex. WordPress has a handy function to strip shortcodes from a string.

echo $your_clean_url; // should output

Here's a function (tested) that will remove your _"unwanted"_ shortcode, and any other one.

$start = "[" . $shortcode . "]";
$stop = "[/" . $shortcode . "]";
$cleanFirst = str_ireplace($start, '', $content);
$cleanSecond = str_ireplace($stop, '', $cleanFirst);

Will php documentation conflict with wordpress documentation?
Hi I have a php script that makes liberal use of
> `/* */`

> `//`
my question is will that conflict with wordpress since the wordpress engine often reads variables inside those things?

I worry my documentation inside my script could cause wordpress to do unexpected actions or worse create a security vulnerability | I believe the practice of including additional data within PHP code comments is typically called _annotations_.
WordPress core makes no use of annotations technique for any code runtime tasks and doesn't have an API for such purpose.

Filter yoast canonical add_action priority

I tried using this as I can see the `WPSEO_Frontend` was the declared class where the `add_action( 'wpseo_head', array( $wpseo, 'canonical' ), 20 );` is located... But ended-up to broken site. | You would need to look in the Yoast plugin to find what the global class is that is referred to as `$this`, so that you can access it outside the class context. If it was for example, `$wpseo`, in your functions.php you could do something like:
$wpseo = WPSEO_Frontend::get_instance();
remove_action( 'wpseo_head', array( $wpseo, 'canonical' ), 20 );
add_action( 'wpseo_head', array( $wpseo, 'canonical' ), 55 );
To find the class name to use, look for the name of the class that contains the `add_action` with `$this` in it as you have already, and then get the instance of that class, like `$wpseo = WPSEO_Frontend::get_instance();`

Organize functions.php
What's the best way to organize functions.php for performance?
I have a couple of add_action calls, few more add_theme_support and couple of add_filter and 4 additional functions. For breadcrumbs, stylesheets, registering menu and widgets.
Is there an order we will need to follow? For example first all the add_filter functions, then the add theme_support etc.
Not sure if it's relevant to add the code since it's a general question. If needed, I would gladly update this post. | Doing this simply won't make a significant performance difference, instead organize your customizations with clear headings so you can find and edit things faster later... in other words, organize for development in this case, not for the frontend.

How to localize something coming from theme customizer
<p><?php echo get_theme_mod('simplisto_p'); ?></p>
something is saved in the database through a theme customizer and then pulled through `get_theme_mod`.
# My Question →
How to localize this? `_e` something of this sort to be used. I can use this on normal strings but confused how to do this here. | If it's a text field, why would you? The user can put in whatever they want in their own language. If it's some sort of select then you just localize the options.
Regardless, you're not supposed to put variables or code inside `__()` functions because that's not how translations work. WPML has its own way of translating theme options that doesn't involve `__()` functions for this reason. | stackexchange-wordpress | {

Security for data obtained from the database
I am getting information from the database to show it to the user, example:
$data = (get_option('config')) ? get_option('config') : false;
I need to display this data when loading the webpage, example:
<label><?php echo $data['title']; ?></label>
<input type="text" value=" <?php echo $data['value']; ?> " >
Is it necessary protect this data before showing it to the user, if the information is obtained from the database?
_Thank you very much_ | Well, it depends on the context. Usually we don't need to protect data for only showing it in frontend. **_But the best practice is, always escape or validate data, no matter where they comes from._** Like for your case you can do that like below-
<label><?php echo esc_html( $data['title'] ); ?></label>
<input type="text" value=" <?php echo esc_attr( $data['value'] ); ?> " >

What is the section ID (name) for "Menus" in the Customizer?
I browsed many articles to know the section Name of the "Menu" in the theme customizer. Here are the few resources that proclaim and identifies that the default section name is "nav" →
1. <
2. <
Currently, there are 5 fields that are resting in the →
title_tagline - Site Title & Tagline
but as soon as I change their section name to :
'section' => 'nav',
The fields do not appear inside the menu section. whats the issue? | _Customizer > Menus_ is a _panel_ named `nav_menus`.
_Customizer > Menus > Menu Locations_ is a section inside the `nav_menus` panel called `menu_locations`.
Each menu is added a little differently, but I believe they are sections inside the `nav_menus` panel whose ID is `nav_menu[menu_id]'` where `menu_id` is the `term_id` of the menu.
_Customizer > Menus > Add a Menu_ is a section inside the `nav_menus` panel called `add_menu`, with a priority of `999`.
Browsing core code is the best way to find this stuff out. All this stuff is in `/wp-includes/class-wp-customize-nav-menus.php`

Change the HTML of the comment form that is generating somewhere from the core Wordpress

I am sure that there must be certain way to achieve this(Modify the core comment form HTML). | You can write your own custom HTML structure for comment listing. Inside your `comments.php` file, there will be a call to `wp_list_comments()` function. Find it, and pass your own function as its callback:

Now, create a callback function and start implementing your own HTML structure. This function accepts 3 arguments. Here is a basic example:
my_function( $comment, $args, $depth ){
$GLOBALS['comment'] = $comment;
// You have access to comment's ID and other

Woocommerce cart page - Add "Free" to the shipping label when shipping is 0
I use a custom shipping plugin for my WooCommerce called Table Rate. When the cart's total is more than X $, the shipping cost is set to 0.

I would like that when the shipping is 0, it adds the text "(Free)" after "Postal delivery" in the cart and checkout page, but I can't find out where this is managed in WooCommerce.

What am I doing wrong? | You're overwriting the defaults passed to the filter, one of which is `echo`, which is `false` by default for the widget.

Importing ACF code in other page templates

Right now I need to copy paste the code and if I want to change anything I need to go through all the pages that are using this ACF group and change the code.
Is it clear what I mean? Is this possible?
Thanks! | You could make one php file (not a page template) for the code of that group. Then you can include that file on the pages so you only have to edit one file to indirectly edit all the files that included that file.
You can do this with the get_template_part function
For example: You create a php file with the name of the group or something to remember it by like normalpage-code.php. you can place it directly in your (child) theme or create another directory and place it there. then in your page templates you can do:
<?php get_template_part( 'normalpage','code' ); ?>
or if you have it in another directory in your theme:
<?php get_template_part( '/anotherdirectory/normalpage','code' ); ?>
You could also use the php include function combined with locate_template to pass variables from the page template to the code for the group.

Increase per_page limit in REST API
WP 4.8.2
We need to increase the per_page limit on responses to a REST API request. afaik – the limit is 100
There used to be a way to filter that parameter, but it seems this filter hook is no longer working: `rest_post_collection_params`
Is there any way to increase that limit without hacking the code?
We understand the repercussions of increasing the limit, but we need to exceed the per_page in a _single_ call for use in code that will not be distributed. | The collection params accessed via that filter appear to describe the available query params but are not actually used in the query.
I think what you actually want is the `rest_{$this->post_type}_query` filter which allows you to modify the args before they are passed to `WP_Query::query()`.
Also keep in mind that on the API request the `per_page` arg might be set, but internally that is translated to `posts_per_page` for the actual query args.
Edit: I think I misread the original question...
The `rest_{$this->post_type}_collection_params` does indeed describe the available params.
You should be able to set the `per_page` max at `$params['per_page']['maximum']`. | stackexchange-wordpress | {

Gravity Forms custom Field entry
I've setup a pretty long form using gravity forms, I have gravity custom fields installed and was hoping I could then create some custom fields using "Advanced custom fields" plugin.

Wordpress Yoast SEO plugin Post Save/Update Issue
**The Problem**
Whenever the Yoast Premium SEO plugin is active, posts are unable to save/update properly in the Admin Menu. After hitting the Update button, I found that all the custom theme shortcodes within the post were being rendered (without the CSS) instead of me being returned to the post editor. With debugger enabled, I was receiving errors like:
`Cannot modify header information – headers already sent by (some/file.php)` | **The Solution**
After WAY more research than I cared for and ultimately not getting a straight answer, I started to realize that the custom shortcode I was using to create HTML might be to blame. I was creating content by closing the `<?php` tag and reopening it after the html was finished. Turns out, I should have been using an output buffer like `ob_start()`/`ob_get_clean()` and returning the code instead.
Before:
`if (argument > 0) { ?> <p>Some text</p> <?php } `
After:
`if (argument > 0) { ob_start(); ?> <p>Some text</p> <?php return ob_get_clean(); } `
This returns the buffered HTML and allows any filters or echos to take place on the shortcode properly. Once this change was made, Yoast (and a couple others like Relevanssi) started working as they were intended to.
Now it's possible that you might get the same debug errors for other reasons, but in this instance, it boiled down to my custom theme not producing shortcodes correctly. | stackexchange-wordpress | {

How do I sanitize the str_replace function in javascript variables

0 => string '4/7/2018' (length=8)
1 => string '11/18/2017'(length=10)

Result Output
var disabledDays = ["4/7/2018","11/18/2017"];
How do I sanitize the above section in **The Code** | `esc_js()` is intended for escaping data for use within an HTML attribute.
If you want to escape data for use within an inline script, `wp_json_encode()` should be sufficient.
For example:
var disabledDays = <?php echo wp_json_encode( $iva_disable_days ); ?>;
This outputs:
var disabledDays = ["4\/7\/2018","11\/18\/2017"];
If you check the variable in your dev tools console, you will see that it is being parsed correctly:
, the second param to `wp_json_encode()` is a bitmask of options:
var disabledDays = <?php echo wp_json_encode( $iva_disable_days, JSON_UNESCAPED_SLASHES ); ?>;
This outputs:
var disabledDays = ["4/7/2018","11/18/2017"];

Table editing in Wordpress
I'm using a table in Wordpress to get my spacing right, but I'd like to remove the border completely or make it white so it isn't visible anymore. If anyone knows how to do that I'd appreciate it.

Why are Shortcodes Disabled in Widgets by Default?
I've looked all around but can't seem to locate a definitive answer for my question: why are WordPress shortcodes disabled by default in text widgets?
It's super easy to enable them, with the line `add_filter('widget_text', 'do_shortcode')`, so I'm just curious as to why WordPress doesn't have that option enabled by default.
Is it for potential security reasons? Page rendering speed? | That has been the case for a long time, text widget existed before shortcodes were added to WordPress, and since then, no one bothered to implement it.

Removing code added to htaccess with insert_with_markers
I use insert_with_markers in a couple of my plugins to add some small bits of code to the htaccess file. What I'm unclear about is how to remove the code and markers.
For example, if I call the function like this:-
insert_with_markers($htaccess, "marker","RewriteBase /foobar");
The result in htaccess is:-
# BEGIN marker
RewriteBase /foobar
# END marker
I can use insert_with_markers, with an empty string, like so:-
insert_with_markers($htaccess, "marker","");
Which removes all the code, but the markers remain, like this:-
# BEGIN marker
# END marker
Does anybody know of a clean way to remove the markers as well?... that doesn't involve filtering the htaccess file with regex? I would like to be able to uninstall my plugins and remove all the traces if possible. | If you know the exact code that is inserted, then read the `htaccess` file with a function that contains `fread` command, and do a search for your inserted text, replacing the found text with an empty string. Then `fwrite` the text to the `htaccess` file.

Using polylang, how can I see which post is the "original" and which are the "translated children"?
I am using Polylang. It is not obvious to me how the relationship between posts are established. I can switch between different language versions of the same post, and I can tell that they're (obviously) different posts in the database. But I can see how Polylang establishes and maintains that relationship. I assumed that there was some meta-value, but that's not the case. Does anyone have any insight?
Initially, I'd like to know this, because I need to create a publish flow where translations aren't accidentally published before the "original". | polylang stores translation in a taxinomy but it's better to access them with the polylang object like that :

// $translations contains an array with all translations of the post

Site header logo and parallax image on homepage do not display on iPhone

get full category structure by post id

- parent 1
- parent sub 1
- child 1
- child 2
- parent sub 2
- child 3
- child 4

Best method to upgrade multisite plugin's numerous database table

As the ACF docs put it, `the_field( 'field' )` is the same as `echo get_field( 'field' )` \- so wouldn't return true or false, but instead simply print (if you get to it).
I'd probably write it
if ( get_field( 'preparation_time' ) ) {
echo get_field( 'preparation_time' ) .
' 40 MINUTES PREP/COOK' ;

Are multiple values from get_post_meta guaranteed to be ordered?
You can create multiple rows in the `postmeta` table for a post with the same key, like this:
add_post_meta( $post_id, "example_key", "value1" );
add_post_meta( $post_id, "example_key", "value2" );
To retrieve the values, you can use `get_post_meta`, which will return an array:
$rv = get_post_meta( $post_id, "example_key" );
// $rv is array( "value1", "value2" )
Is the resulting array guaranteed to be ordered? In what order are the values in? Alphabetical, or date inserted? | **Yes**.
`get_post_meta()` uses `get_metadata()` which in turn uses `update_meta_cache()` to retrieve the values. In the source code we see this part (comment mine)
// $id_column is 'meta_id'
$meta_list = $wpdb->get_results( "SELECT $column, meta_key, meta_value FROM $table WHERE $column IN ($id_list) ORDER BY $id_column ASC", ARRAY_A );

How to move Wordpress theme files into a subfolder without breaking the theme?
I've been coding a Wordpress theme using OOP PHP, node.js and Webpack, and between classes, node_modules, configuration files and Wordpress template files my theme's directory has become a bit messy...
Is there an easy way to move the theme's template files to an `app` subfolder without breaking the theme?
(I've found a similar question but it was asked in 2011, so hopefully something came up over time). | Out of the box WP relies on Template Hierarchy to resolve and load template. The default assumption is that (most) template _are_ in the root of the theme and follow the naming conventions.
Placing template files elsewhere essentially requires rebuilding Template Hierarchy in your code with different assumptions. This used to be crazy inconvenient, but WP 4.7 introduced `{$type}_template_hierarchy` hook, which makes it significantly easier.
As a personal aside I think native WP template simply doesn't scale meaningfully to complex use cases. If there are enough templates to clutter the directory, then I would move to a different template engine (such as Twig) altogether. Of course that is hardly mainstream technique in WP development.
I have an example of template hierarchy override in my Meadow project for Twig integration, but same works for just changing up logic for PHP templates. | stackexchange-wordpress | {

Filter the regular price of woocommerce products

Corrupted nav-menu?
I am currently debugging a WP install with lots of plugins and Avada theme (Fusion core, Fusion Builder)
The thing is I can't edit the current Menu. When I select an item and add it, the spinner pops, unpops, and nothing more happens actually.
I digged a little and tried to delete all terms and taxonomies in database but now. I can't create nav-menu because it is created with term_id 0. Even with wp-cli, wp create menu 'test' says :
`Success: Created menu 0.` with each new invocation of the command with different menu names.
What is wrong? Anyone has tips to reinitialize menu datas ? | I resolved my issue.
This was due to the lost of indexes, primary keys and auto_increment feature in my database structure due to export/import database actions.
With bad export options, the indexes and primary keys at one point, weren't re-created during import and so on....

read_private_pages capability not working for new role
I have created a new user role - _vendor_ \- with the capability to `read_private_pages`, but when I log in as such a user, and go to a private page I cannot see it.
Here is my plugin code:
function fc_add_role($role, $display_name, $capabilities = array()) {
if (!empty($role)) {
return wp_roles()->add_role( $role, $display_name, $capabilities );
}
}
if (!get_role('vendor')){
fc_add_role('vendor', 'Vendor', array('read_private_pages', 'read_private_posts'));
}
And when I go to my private page as a vendor, it just shows:
> **Oops! That page can’t be found.**
>
> It looks like nothing was found at this location. Maybe try one of the links below or a search?
What am I doing wrong? And how can I make it so vendor users can read private pages?
NB - When I log in as admin, I can see the private page. | Your capabilities should be a key value pair:

I renamed my server from http to https and now I can't login
I set up a WordPress site under a temporary domain name, using http protocol. It works fine.
Now I want to make it live under a completely different domain name, with https enabled.
My first step was to obtain an SSL certificate for the new domain name. I enabled Apache to accept https requests using the new domain name. I verified this was working by accessing the site using the new name. Of course, since the site name in WordPress general settings is the old http address, my browser was redirected there.
So I logged in to wp-admin and changed the site url fields to the new domain name (with https).
As soon as I saved the page, I was redirected to a login page (which seemed to be missing its css). But trying to login on that page just redirects back to the login page again.
I did this successfully before with another site, so I'm confused why it doesn't work this time, as I think I have been through the same steps. | Have you tried a database migration plugin? WP stores serialized data about the URLs so often simply updating the home and site_url option is not enough. Also try an Incognito window or another browser to see if you have old redirects cached. | stackexchange-wordpress | {

can the footer be included on a child theme
If the footer can be included, what must be written on the child theme `footer.php` page to get it started. I should say I am new to child themes and have already shut the site down by including the entire parent stylesheet/functions.php. After reading about that same rookie issue that another member experienced I immediately went to cPanel to delete it.
However before I upload my updated child theme, I'll wait for an answer concerning the `footer.php`. Of course I would like to edit it on my child theme to remove the WordPress branding only once. | Take the whole footer.php from the parent theme and copy it to your child theme. Your child theme will override the parent footer now. Any changes you make to that footer file in the child theme (ie removing branding) will affect the site.
This is usually better than starting with a whole new footer.php especially if the theme you are using is overly complex.

Append class to posts page
I'm trying to style something unique to the Blog/Posts page, which isn't on the front page. The body tag right now looks like this:`<body <?php body_class() ?>>`
But doing this `<body <?php body_class('blog') ?>>` only returns `<body class="logged-in">` or just `<body>` if I'm not logged in.
I've tried:
<body <?php if ( is_home()) {
echo 'class="blog"';
} else {
body_class(); }?>>
It sort of works but it replaces the "logged-in" class entirely. There has to be a way to append classes to the body tag for posts pages right? | In your theme's functions file, use the `body_class` filter to add new classes:
function wpse_282694_body_class( $classes ) {
if ( is_home() ) {
$classes[] = 'blog';
}
return $classes;
}
add_filter( 'body_class', 'wpse_282694_body_class' );
If your category archives, tag archives, date archives and search results also need the same styling, which is fairly commin, check for each of them like so:
if ( is_home() || is_date() || is_tag() || is_category() || is_search() ) {}
Note that I didn't use `is_archive()`, because that would also affect any custom post types you might be using. | stackexchange-wordpress | {

Unable to access website admin page - 500 error - how to change landing page
Help is required to solve a problem created by a stupid mistake.
Our website is hosted by Godaddy and created with Wordpress. It had been set up and running smoothly for long.
Recently We wanted to keep the website down for some time as we wanted to modify some contents. So with a "brilliant-idea-moment", using wp-admin login, in the dashboard, the landing page name was changed from "mydomain.com" to "mydomain.com/404".
Now we are not able to access the wp-admin login page at all to revert back, as it keeps redirecting it to "mydomain.com/404/wp-admin", a page which does not exist so giving a 500 error message.
Is there anyway, we could change the landing page back to original, through hosting admin or cPanel by editing any specific file?
Your assistance would be highly helpful. | Connect to you Cpanel through godaddy and search for `PHPMyadmin`. The interface that allow you to manage your database.
Then search for a table called `wp_options` then in this table you should be able to find the url of the site in two places ( **siteurl** , **home** ) and you should be able to change it back to the domain name.
After this you will be able to access the admin again, then you should go to the permalinks settings and hit save (without doing any changes). This will correct your url rewriting. | stackexchange-wordpress | {

if ( isset( $_POST['first_name'] ) )
update_user_meta($user_id, 'first_name', $_POST['first_name']);

How to add custom classes to a Wordpress theme HTML tag?
I've been googling how to add custom classes to the HTML tag of a Wordpress theme, but it's a tricky issue to research because all results are about HTML tags in general, not the **specific HTML tag** that opens a document. I want something like this:
<html class="custom-class">
I know the `body_class` filter can be used to customize the body's classes, but there seems to be no such thing for the html tag, yet Wordpress does output some classes for `<html>`, so they must be coming from somewhere...
Any ideas? | There is no designated template tag for classes on `html` container.
For example in latest core Twenty Seventeen theme they are hardcoded:
<html <?php language_attributes(); ?> class="no-js no-svg">
For proper customization you would likely need to create a child theme and override repsective template (likely `header.php`) or settle on manipulating classes with JavaScript. | stackexchange-wordpress | {
