links format change "on clic"
i have an issue on my site, and i don't know where it comes from.
every link "change" ( comes bigger & change place ) when i click it.
on menu link, they still are clicable, but with link in page, it doesnt work at all.
exemple :
<
try to click on "aix en provence" to see what happen.
thanks in advance for your help | It comes from the css definition in style.css around line 125. There is this rule:
.hotel-detail-booknow a, a:active
defined that gives the link its enormous size and blue colour. I would guess that it should be:
.hotel-detail-booknow a, .hotel-detail-booknow a:active
In your case, the rule is applied to all clicked links, not just the ones within a `.hotel-detail-booknow` element. | stackexchange-wordpress | {

Enable right click on WordPress site
I can not right click on my site and I don't know why!
Is there any function to enable right click on the site? | This isn't something WordPress is doing but probably your theme. Perhaps it's an attempt to get people to not download your images or code, this is basically useless and doesn't prevent anything like that.
Your theme might be using something similar to this...
`document.addEventListener('contextmenu', event => event.preventDefault());`
Try searching your theme files for `contextmenu` and see what you can find. | stackexchange-wordpress | {

Wordpress 404 on style.css but not on all pages
I have noticed an issue when running a site audit on all of my websites using SEMrush I picked up the error:
> issues with broken internal JavaScript and CSS files
Examples
> < < <
All the sites are WordPress and some use a child theme and some do not, the example site does use a child theme.
The style.css error is currently on 34 pages but not all.
I did update the permissions after editing the files but nothing has worked, the current permissions are dir 755 and the stylesheet is 644.
I am not sure what the issue is as it does not look like the permissions are the issue and if it was the child theme not loading the stylesheet then it would break across all the pages. | By looking at the source of `/about-us` the culprit seems to be the contact form in the footer, present in more pages of your website.Look here.
Look at the Code module inside the divi builder, you'll see a `<link>` tag referring to a `style.css`: that's the code that's causing your 404. By the fact that the link tag is placed before a form I'm getting you wanted to style the form with some custom css? In that case just use the Divi theme options page and paste the css there, giving a proper id or class to the form. | stackexchange-wordpress | {

Comment status shows 'closed' in db, but it shows 'open' when i echo it
Here is database ss. And comment_status is `closed`
I’m almost certain that somewhere in your page you make another wp_query and modify the global `$post` variable. So when you’re printing the comment status it’s showing the real value but for different post.
If you do such wp_query, then you'll have to remember to use `wp_reset_postdata` after that loop, so the global `$post` variable is restored to its original value. | stackexchange-wordpress | {

How can I mass-update/save all WordPress posts and pages?
I'm using a free SEO plugin for WordPress called Rank Math - <
Overall, I like it a lot. But it has some problems for users with existing WP sites who are importing data from another plugin like Yoast.
Rank Math is relying on individual posts and pages to be edited (not using WP's bulk quick edit feature, but opening each post and re-saving them one-by-one).
This happens with author sitemaps for example. An author's page is only added to the sitemap if I manually open and re-save one of their posts and then re-save the sitemap settings. It doesn't find and add existing authors otherwise.
Is there any way to simulate clicking the "update" button for all posts and pages without changing any actual content in a circumstance like this?
Thanks. | Add to your functions.php file, but dont forget to take it off after use it !!!!!
function update_all_posts() {
$args = array(
'post_type' => 'post',
'numberposts' => -1
);
$all_posts = get_posts($args);
foreach ($all_posts as $single_post){
$single_post->post_title = $single_post->post_title.'';
wp_update_post( $single_post );
}
}

class="remove_field" style="margin-left:10px;">Remove</a><div></div>
</div>
But not the remove , nothing happen when i click on the remove hyperlink Any idea pls | This isn't WP related but Its not working because you are trying to add an event to a dynamically created element.

Personalize checkout text

I am able to remove the input fields, but I cant find a way to remove the text.

How to work with constraints on wordpress user metadata?
For example, I want to add a custom user metadata field for projects he is assigned to. But this field must have a foreign key constraint to another table to make sure that the project it is referencing, is valid.
Is there a way to handle this scenario with pure user metadata instead of creating an extra table to link the users with the projects? | You won’t be able to do this with meta.

The category loop output is still `<li class="product-category product"> ...` and can't find where to change this.

W3 Cache redirects to front page when I press purge all caches
I migrated my site to a new server. Everything seems to be fine, but the browser is redirected to the frontpage when I save configurations in either the "W3 Total Cache" plugin or in "Duplicate post" plugin. It does save the edits, but it´s annoing with the redirect.

define('WP_HOME','
define('WP_SITEURL','
In my wp-config.php
And with these google results: Redirecting to home-page when saving any edited code <

I tried to change the wp permanent link options in the admin settings too.
The "Duplicate post" plugin was installed after the site migration. | Okay, I found a solution. To anyone in the future having this problem here's what i did:

Newbie: Help with Vertical Spacing on Footer Widget

meta_post_meta return value 1

If you have only one meta field with key `prep_time`, you’ll get:

On the other hand I’m pretty sure that’s not what you’re expecting, so you should pass `true` as the third param like so:

What does $temp do?
I am new in WordPress Development. And I saw a sample which uses `$temp` to store the old `$wp_query` instance before instantiating a new `WP_Query`. I guess it is used to return original state when showing some posts other than the current `$wp_query` contains. But, I would like to be sure and learn other reasons. And I wonder what is the best way of this type of operations. | What any variables used in samples do depends entirely on that specific sample. If a sample assigns a query to a variable called `$temp`, then that's what `$temp` does. It doesn't mean anything else, it's just what's shown in the sample.
Guide and tutorial writers can and will create and use any variables they want. You will need to read and understand the guide to understand what they're doing, or ask the author if you're unsure. If you need to, learn basic PHP first, as it will help a great deal.
That being said, what you've described -- modifying `$wp_query` directly and then resetting it -- is something you should absolutely **_never_** do. Do not take further advice from any source that told you to do this.
If you need to query posts for your own purposes, use `new WP_Query()` or `get_posts()`, and if you need to modify the main query, use the `pre_get_posts` filter. These are thoroughly documented across the web, and this site, if you need to know more. | stackexchange-wordpress | {

How to show metabox on page if it is using a template

How can I remove the ::after CSS selector which is automaticaly appended to the_content()?
I have a CPT which displays meta values after the_content() in the front end, and this ::after selector is messing with my layout. The selector always appears right after the final element inside the_content(). | It has nothing to do with `the_content()`.
`::after` is a pseudo element that's added with CSS. Note that the `::after` element in the dev tools is only there to help development. It does not exist in the HTML source.
So your theme's CSS must be adding it to whatever element is wrapping `the_content()` in your template. You can remove it by setting `content: none;` on the selector for it. For example, if the element that's wrapping your content is `<div class="entry-content">` then the CSS to remove it could be:
.entry-content::after {
content: none;
}
The rules of specificity still apply though, so whatever selector you use to remove it needs to be more specific than the one that added it.
Also keep in mind that your theme likely does this for a reason. Most commonly elements like this are used to clear floats and prevent float-aligned content, like images, from breaking outside the parent element. | stackexchange-wordpress | {

How to hide specific Gutenberg blocks settings from users

This could be difficult, especially if you don't have any JS and/or block editor dev experience.

To answer to your question:

yes, you need to create subdomains on your server using cPanel or plesk.
> if yes, do I have to install a WordPress installation in this subdomain before creating a site within the multisite admin dashboard, or after?
You don't need to install wordpress for the subdomains. Be careful to point the root of every created subdomain to the root of your wordpress multisite installation. Multisite network will share the same wordpress installation, so you don't need to reinstall it each time you add a subdomain.

Just display content between shortcode brackets

Everything works fine, but what I want is 'post_title' = > 'rand', but the 'rand' seems not to work. What am I doing wrong? | The short answer is "you can't do that." Take a look at the Codex.
When using orderby as an array the value can either be `ASC` or `DESC`. If you want to set `rand` you would do so as a key only. That being said, ordering by random will override any other orders, so you won't really get a benefit from ordering by `tipo_prodotto_clause` first.
'order' => 'ASC',
'orderby' => 'rand',
Also make sure you take note of the required context for orderby rand:
> Random order. You can also use 'RAND(x)' where 'x' is an integer seed value. **Note an "order" parameter needs to be present for "orderby"** **rand to work.**
A piece of advice: ordering randomly is highly discouraged. The query does not perform well in mysql and has the potential to break caching on a site for every request or not appear to work if caching is less flexible.

but like this
[add_to_cart title="XXXXXXXXX"] | default woocommerce shortcodes won't do that. you'll need to write something custom to get the product by title, grab the ID from there, and then call the add to cart shortcode using the ID. something like this:

if (basename(parse_url(wp_get_referer(), PHP_URL_PATH)) == 'my-search-page') {

(Also note `wp_get_referer` is deliberately misspelled. It originates in a misspelling in one of the web standards)

How to remove the WooCommerce Product->Category thumbnail from admin

add_image_size not working with after_switch_theme
This is a weird one - this exact code works with `after_setup_theme` but not with `after_switch_theme`. Of course I would rather use `after_switch_theme` because `after_setup_theme` runs all the time - but it just will not work.

add_image_size( 'hero_image_md', 767, 460, true);
add_image_size( 'hero_image_sm', 549, 575, true);
...
}
For reference: yes, I am switching the theme. Yes, I am regenerating the thumbnails. And in my `wpdocs_theme_setup` function I'm also adding custom roles that work regardless of which hook is being used. Any thoughts? | The reason adding custom roles works on `after_switch_theme` is because roles are saved in the database. In fact, because it saves to the database, it should _not_ run on `after_setup_theme`.
`add_image_size()`, on the other hand, does not save anything to the database, so needs to run on every page load, and needs to be hooked on a hook that runs for every page load. So `after_setup_theme` is the correct hook to use. | stackexchange-wordpress | {

how do links move when I move my site?
Very new at this, so maybe I am missing some fundamental understanding of how WordPress handles links. But, I'm building a website on my local machine, expecting to upload it to a provider when I'm done. Right now everything resolves to localhost.
Here's the problem. One of the pages has a list of links to other pages on the site. WordPress created those links as <
Shouldn't there be a placeholder for the domain name there instead of a hardcoded localhost? Or better yet, shouldn't they be relative links instead of fully qualified URLs?
Or will WordPress automatically fix those links when I move my site to a provider? | Some links (those built in code) will automatically change to your new domain.

Woocommerce: limit user to see only the products he created
I have this code where the authors can see only own posts. I need the authors to see only the products they have created on woocommerce. I know the woocommerce products have no authors by default, but I can add this with a plugin. Whats I want to do is to change this snippet to limit the lists of products in the custom post type of woocommerce.
Someone know the best way to do that?

global $pagenow;
if( 'edit.php' != $pagenow || !$query->is_admin )

if( !current_user_can( 'manage_options' ) ) {
global $user_ID;
$query->set('author', $user_ID );
}

if( !current_user_can( 'manage_options' ) )
to this one:
if( !current_user_can( 'manage_options' ) && 'product' === $query->get( 'post_type' ) )
would do it.
Brief explanation: I added a second condition which checks if the query is for WooCommerce products where the post type is `product`.
## UPDATE
If you want to make certain that the code runs only on the products page (WooCommerce -> Products), then you can (remove the `global $pagenow;` and) change this:
if( 'edit.php' != $pagenow || !$query->is_admin )
to this one:
if( !$query->is_admin || 'edit-product' !== get_current_screen()->id )
And instead of relying on the global `$user_ID`, you should probably use `get_current_user_id()`: `$query->set( 'author', get_current_user_id() );` :) | stackexchange-wordpress | {

Use Repository Pattern in WP theme

Can I clone plugin folder to another directory so that I don't have to reinstall them?
I built a multisite network and it got broken due to a developer who now claimed that it can't be fixed: The subsites' dashboards can no longer be accessed and the pages give the error message "page cannot be found". Since I haven't worked on it for very long, I am fine with "abandoning" the site and restarting.
Right now, I would like to move all my installed plugins (paid and non-paid ones) from this site to a new single site installation (not multisite). Is this possible? How do I do it?
Thank you | Sure you can copy the folders and their contents over. A few caveats:
* they will start as deactivated
* their database records will not be copied over automatically. Some paid plugins store the license key in the database.
* there may be compatibility issues if your new site is on a different version of WordPress, PHP, etc., Especially since you said the site is a couple of years old and you haven't touched it in a while
Personally I would rather try to fix what you have and then go from there. "Can't be fixed" is subjective. If you reinstall the core WordPress files, network deactivate the plugins, and network-wide deactivate non-core themes, you still can't get into the subsites' dashboards? | stackexchange-wordpress | {

$new_id = wp_insert_post($post_arr, true);
kses_init_filters();
if (is_wp_error($new_id)) {
$this->write_log("error occurred in wordpress post entry: " . $new_id->get_error_message() . " " . $new_id->get_error_code(), true);

return;
}
if($url) update_post_meta($new_id, 'source_link', $url);
else {
// wp_delete_post($new_id); // Move post to trash
$deleted = wp_delete_post($new_id, true); // Permanently delete post

Use
$authors = get_users( [ 'role__in' => [ 'auther'] ],
// add other parameters
);
Then loop through $authors to create your own list.
foreach ( $authors as $author ) {
// your list goes here

Check and load class of theme from a plugin
I'm in the process of breaking down a theme to a bunch of plugins, I wanna do it one by one so hell won't break loose.
Question is, Suppose I have a plugin which depends on a class from the theme, where and how should I validate his existence and load it, and if not exist how do I properly show an error and avoid loading the plugin, is it on the activation hook? I'm pretty new to plugins, and would love to get best practices, or any good docs references regarding my issue, thanks!
I don't need to check another plugins existence, just another code that is currently part of the theme. | I'd recommend to not use methods from your theme in the plugins. **Only the other way around. Let your plugins provide methods to be used in the theme.** Then you could simply use `is_plugin_active()`.

Nonetheless you could use PHP's `class_exists()` to check for the existence of a class. Another common practice seems to be to let your plugin `die;` at the very top before anything else can be loaded.

How to disable updates in WordPress theme
I am working on a WordPress website. Earlier before me, there was one another guy has worked on that website.
Now he has done all his changes in parent theme without creating a child theme. Now, what should I do to prevent updating theme?
Also, I know it is nearly impossible but If anybody can suggest me any step to separate both changes. that would be more helpfull.
Theme is twentyseventeen | First of all, it is a very bad idea to modify the original theme without creating a child theme. Disabling updates of such theme is even worse idea, because without updates, your site may get infected or attacked.
So the long-term solution would be to:
1. Check the version of modified theme.
2. Download that version from official repository.
3. Compare the original files with modified ones.
4. Create a child theme containing only necessary modifications.
If you need to disable the updates for a few days, there is an easy way to do it - just change the version of your theme to 9.9.9 - WordPress will think that it is newer than the one in repository and it won't get updated. (BUT... Don't think of this hack as a solution - it's just a dirty temporary fix and you still should perform the process from points above). | stackexchange-wordpress | {

How to have the Header show different content on different pages?
I made a Navigation (primary) via Appearance->Menus which navigates the user to anchor tags on the side, but I also have subpages, where I want a different navigation - only with my 'Home'-button in it. Which would mean I need to get rid of the other navigation points.

`<php if (has_nav_menu ( 'primary') ) : ?>`
Can i just do an `else` with another navigation?

// just show a link Home for the subpages...

Add to array, redirect and display

$url = get_site_url(null, '/redirect_to_two');
wp_safe_redirect( $url );
}
public function two(){
$this->display();
}
} | If you need to pass some data over the redirect, you can do that by adding parameters to the redirect url with `add_query_arg()`. But other more elegant solutions might exist also.
Single parameter,
wp_redirect( add_query_arg( 'notice', 'success', get_site_url(null, '/redirect_to_two') ) );
exit;
or multiple parameters
wp_redirect( add_query_arg( array( 'notice' => 'success', 'foo' => 'bar' ), get_site_url(null, '/redirect_to_two') ) );
exit;
Then use `$_GET` to grab the parameter(s),
if ( ! empty( $_GET['notice'] ) && 'success' == $_GET['notice'] ) {
// Do whatever.
}
If I'm not mistaken, I don't think you need to worry about unsetting arrays as data doesn't normally persist in WordPress. Once you do a redirect all the data in your `$variables` are gone. | stackexchange-wordpress | {

What permissions does a role need for the user to be assigned as the author of a post?
I have a Wordpress site with custom roles (except for administrator) and now wanted to create a role so that a user with this role can be manually assigned as the author of a post. I thus created a role which had all permissions checked in the "post" submenu, but none in the others (since this role is only there for this reason).

What permissions does a role need so that the user can be assigned as the author of a post? I would really like to not make this user an administrator | You probably need to add 3 capabilities:
* edit_published_posts
* publish_posts
* delete_published_posts
but at the very least, you need to add `publish_posts` as that is the capability WordPress uses to determine what users are shown in Authors drop-down.
Note: Changing capabilities is stored in the database so the recommendation is to modify these values via a plugin and only when the plugin is activated or deactivated rather than on every request. | stackexchange-wordpress | {

Do I need to sanitize `$atts`? If so, how please?
Help appreciated. | Of course you do have to sanitize it and escape it.
Otherwise any author/editor of the site will be able to perform any query on your database.
First of all you should never create SQL queries like you do in your code. Never concatenate the raw SQL with anything that is variable or comes from user.
You should use `$wpdb->prepare` for that.
So your code should look more like that:
$sql = "SELECT COUNT(meta_key) as count FROM {$wpdb->usermeta} WHERE meta_key = %s && meta_value = %s";
$member_count = $wpdb->get_var( $wpdb->prepare( $sql, 'mepr-address-state', $atts[0] ) );
As you can see, there is also no point in getting all rows (there’s only one) and there’s no point in getting all columns (there also is only one).
That’s the escaping part that will save you from SQL injections.
But yes - most likely you should also put some validation in there - but it depends on what are the available values for that param. | stackexchange-wordpress | {

WooCommerce Description and Short Description <p> tags removal
When adding content into the description and short description fields for a product, line-breaks and
tags are completely removed from the markup. Other than installing Advanced TinyMCE, is there any setting, filter, or hook I need to check to make these fields include
elements.
In review of the Product object array in WooCommerce, it looks like the value for description is wrapped in the wpautop() function, but it doesn't appear to be working (it's possibly I'm just not understanding this part of the code correctly within the plugin).

Note: I only have ACF and WooCommerce installed as plugins. I'm using Underscores as a parent theme to build my own custom theme and product templates. | So, I realized I was using the actual object in the template to call the description `$product-get_description()`. If you're experiencing this issue, then you can wrap this in a `wpautop()`, or you can do what WC actually does (not sure how I didn't remember) and use the simple `the_content()` function to get the description.

Reorder attachements in the media library
I have a plugin that takes an user selected image from the media library, puts some special effects on it, and then saves a copy of the "enhanced" image back to the library using media_handle_upload().
This works fine, but it puts the updated image at the top of the media library, separating it from the original.

However I can't find what column in the wp_posts is used to sort attachments when the wordpress media library displays them.
Any help with this problem would be much appreciated, thank you! | Attachments in Media Library are obtained using WP_Query, so you can modify that query with `pre_get_posts` action.
