Site throws 500 error after upgrading from PHP 5.6 to 7.X
If I try to upgrade to PHP 7 or up (from 5.6), I have one site that is throwing a PHP error.
I have tried uninstalling all plugins and activating the Twenty Twenty theme before changing PHP version. No dice.
Is there a setting in the database or core that would be effecting this? I also tried a default .htaccess file.
EDIT: WP debug.log says:
[10-Mar-2020 23:35:45 UTC] PHP Fatal error: Allowed memory size of 2097152 bytes exhausted (tried to allocate 32768 bytes) in /path/public_html/wp-includes/formatting.php on line 1600

But this seems unrelated, right? The site is having i/o issues as well. | try doing wp_debug true and if the issue is of memory allocation try allocating memory in the wp-config

Plugin throws up 404 on front-end when when enqueuing style with filetime
I'm building a very simple plugin to add social media icons to each page on a site that I'm working on.
I was expecting the following code to enqueue a stylesheet on the front-end:
function myplugin_styles_scripts() {
wp_enqueue_style( 'myplugin-style', plugin_dir_path( __FILE__ ) . '/css/style.css', array(), filemtime( plugin_dir_path( __FILE__ ) . '/css/style.css' ) );
}
add_action( 'wp_enqueue_scripts', 'myplugin_styles_scripts' );
On the front-end, I get the following error in the console:
> < net::ERR_ABORTED 404
The directory and file exist within my plugin. What's causing this? | You're getting the `404` error because you didn't provide the correct URL address of your CSS file.
And that's because of the _first_ `plugin_dir_path()` below which outputs a _filesystem_ directory path (e.g. `/home/user/var/www/wordpress/wp-content/plugins/my-plugin/`):
wp_enqueue_style( 'myplugin-style', plugin_dir_path( __FILE__ ) . '/css/style.css', array(), filemtime( plugin_dir_path( __FILE__ ) . '/css/style.css' ) );
So you should instead use `plugin_dir_url()` for getting the _URL_ directory path for your plugin (e.g. `
wp_enqueue_style( 'myplugin-style', plugin_dir_url( __FILE__ ) . 'css/style.css', array(), filemtime( plugin_dir_path( __FILE__ ) . '/css/style.css' ) );
And note that both the functions include a trailing slash, so in the above code, I intentionally used `css/style.css` and not `/css/style.css`. Otherwise, the URL would contain `//css/style.css` (note the two slashes). | stackexchange-wordpress | {

Change menu based on page template via functions.php
I'm trying to swap out the main menu of a page if it uses a specific page template.
This was working perfectly until I added a 2nd menu to the page.
I would greatly appreciate any guidance on how to target only the primary-menu and not all the menus on the page. I tried 'primary-menu' but did not work.
In functions.php:
add_filter('wp_nav_menu_args', function ($args) {
if (is_page_template('page-template-custom.php')) {
$args['menu'] = 'custom-menu';
}
return $args;
});
Thanks very much! | The `$args` the filter is receiving includes the `theme_location` used when the menu was registered, so assuming your main location is `primary`, you can add the following to your if statement to target only that menu:

is_page_template( 'page-template-custom.php' ) &&
isset( $args['theme_location'] ) &&
'primary' === $args['theme_location'] )

Finding the path of a specific WordPress install
I have recently taken over a WordPress website.
Once I got access to the server I found that there were more than 70 installations of WordPress spread across it (files and DBs).
What is the quickest/easiest way for me to determine which installation is the one that is running the actual live website?
I thought of putting a PHP file into each installation (a file that echoed something along the lines of `$_SERVER['PHP_SELF'];`) - then try and access that file from the site itself, from there I know which installation is the correct one (I can then work out which DB is the correct one from the wp-config).
But surely there is an easier way? I have access to wp-admin, is there anything I can do in there to show me the base install path of this particular WordPress? | If you haven't already figured this out, as you have admin access to the dashboard, just go into Appearance->Theme Editor then add some PHP into the theme's footer.php or functions.php to echo out the location of the install on the server. | stackexchange-wordpress | {

How to fix error message to edit sidebar widget text on a livesite childtheme?

How do you enable scripts on a WordPress installation in Softaculous?

How to add custom script to the particular Product Category page
I am trying to add the script to the particular Product Category page, but the code is not adding it to the category.
**Page (working):**
function wpb_hook_faq_javascript() {

if ( in_category( 'category-name' )) {
?>
<script type="application/ld+json">
</script>
<?php }
}
add_action('wp_footer', 'wpb_hook_faqtocategory_javascript');
But the above code is not working.
**Product Category URL:**
wp-admin/term.php?taxonomy=product_cat&tag_ID=9&post_type=product | `in_category()` should be used inside The Loop (unless if you pass a post ID as the second parameter like `in_category( 1, 1 )`) and only for the default/built-in `category` taxonomy.
For custom taxonomies like the `product_cat` in your case, you should use `has_term()`; however, if you're checking if the current request/page is a taxonomy archive page, you should instead use `is_tax()`:
function wpb_hook_faqtocategory_javascript() {
if ( is_tax( 'product_cat', 9 ) ) { // 9 is the term ID, but you can use the slug/name
?>
<script type="application/ld+json">
</script>
<?php
}
}
Or in WooCommerce (you're using WooCommerce, right?), you can use `is_product_category()`, but you'll need to know the term _slug_ :
function wpb_hook_faqtocategory_javascript() {
if ( is_product_category( 'term-slug' ) ) {

"This is my custom message.", // Text string to display.

isDismissible: true, // Whether the user can dismiss the notice.
// Any actions the user can perform.

{
url: '#',
label: 'View post',
},

Gutenberg - reusable blocks that I can edit? Am I being slow?
I'm either being incredibly stupid or I've misunderstood a "reusable" Gutenberg block.
If I make a block that I need to reuse then it is all very simple to save it and it's placed with the reusable library.
However, if I insert it back into the page and try and edit it then edits the entire block.
My point is that all I want to do is edit the text - not the layout.
What is it that I am doing wrong here? | A reusable block is meant to be a global block...meaning that you can insert it on any page and if the content is updated, it will update across the entire site. This is handy, for instance, for call-to-action content.
However, if you want to have a reusable block that has all of the same styling and features, but just need to change the text, you can convert an instance of that block back to a `regular block` by clicking on the three dots (block settings) menu and clicking "Convert to Regular Block":

What happens to the default query when I use WP_Query?
I'm working on a custom theme based on Underscores. In my `archive.php` I want to style the first post in the loop differently than the rest, so I'm running one `WP_Query` to fetch the first post, and another to get the remaining posts.
What I'm wondering is -- since I'm handling the queries myself, what happens to the default query that WordPress is running implicitly (that is, the one I'd normally be iterating over with `while ( havePosts() )`? Obviously for performance reasons I don't want to run any unnecessary queries, so is there a way I can stop it?
I'm somewhat familiar with the `pre_get_posts` hook, but I'm not sure how I would use it since, as I mentioned, I'm not just trying to modify the one default query -- I need two (unless there's a better way of doing this). | WordPress always queries a default set of posts when you view any sort of archive. So if you run your own query as described you’ll end up with 3 database queries instead of 1.
You should not develop your template the way you describe. The standard WordPress templates should all use the default query. You’ll be coming back as the 400th person to ask why pagination isn’t working properly if you do it this way, among other potential issues. If you want to style the first post differently there are plenty of ways to do that without querying it separately, from CSS techniques to logic in the template. If you have something specific you’re trying to accomplish, I suggest posting a new question with those details. | stackexchange-wordpress | {

Hide inventory message on product page based on available stock quantity
I have a site which needs to display the available stock left for each product, which is fine. However some products are print on demand (i.e. infinite stock) so I have these loaded with 99999999 in stock. Obviously I don't want this stock level to show on the front end of the site as there isn't really any physical stock.
I've found the below snippet - can this be edited to say, for example, if the current stock is more than 1000 then hide the stock message?
function my_wc_hide_in_stock_message( $html, $text, $product ) {
$availability = $product->get_availability();

Need to pull parent category and slug - only pulling daughter category
I am tweaking a theme for my friend, and I am using the following:

How can I achieve this? Many thanks :D | There are functions for retrieving a term/category link (i.e. URL to the term archive page) and in the case of the default `category` taxonomy, you can use `get_category_link()`:
<a href="<?php echo esc_url( get_category_link( $category[0] ) ); ?>"><?php echo $category[0]->name; ?></a>

How to remove google font in WordPress for only single page?

How can I access variables from theme in child theme?
I am using a WordPress theme (Kalium Theme) as a base and extending it with my own child theme, which includes javascript & php files. The parent theme uses a image carousel plugin (Flickity) to display e.g. product image galleries doesn't work exactly the way I want it to. I need access to the flickity instance outside of the Kalium main libraries. Can you advise me on how best to access the carousel objects and manipulate them in javascript without directly changing Kalium Core files? I am talking about adding event listeners to the flickity instance and changing settings in the instance. | You would access it the same way that Kalium does. Code in child and parent themes all have access to the same things, there is no sandboxing or walls of separation dividing the two. Any functions or variables in the parent theme are accessible in the child theme the same way they'd be in the parent.
Having said that, overriding PHP functions and classes in the parent theme may not be possible if they don't provide actions and filters, and can't be unhooked.
Similarly, javascript is javascript, once it's loaded into the browser page, it has very little to do with WordPress and parent/child themes. You'll probably have to deregister the parent themes javascript and then add your own that does everything the parent theme does, but your way.

Single posts for one CPT UI post type are 404s
I have an instance of WordPress with multiple custom post types created with the CPT UI plugin.
The posts for one of the custom post types are shown on the front end as 404s. The other custom post types are fine.
I've tried flushing permalinks, deleting and remaking the post type, disabling all plugins, changing my theme.
I'm not entirely sure what else to check.
Thanks in advance for your suggestions,
Nathan | Based on our discussion in the comments I think the issue you're experiencing is that you've got a slug conflict with WooCommerce 'downloads'. Your CPT isn't conflicting but the slug it's applying is probably conflicting with WooCommerce's slug for downloads.
To rectify this, simply prefix your slug or adjust it:
`/dls/`
`/nthn_downloads/`
`/themename_downloads/`
Anything of that sort that'll differentiate it from the download endpoint & urls that WooCommerce generates for downloadable products should be sufficient.
Using the CPT UI plugin you would just edit your Post-Type and scroll down to the area pictured here...

Use wp_remote_get to get JSON instagram feed from public profile
I'm using the curl php library to get the instagram json feed from a given public profile. I want to use `wp_remote_get()` because on the host I'm using for this project, I don't have the ability to use curl to request the json feed, I've noticed that my actual plugin script will work well on localhost, on netsons and aruba but not on tophost.
I don't know if the function included in wordpress will do the same thing so my question is, will `wp_remote_get()` return to me the json feed if I provide the instagram url? See the example above:
$feed = wp_remote_get(' | Yes, it will do the same thing.
Taken from the official docs:
/** @var array|WP_Error $response */

if ( is_array( $response ) && ! is_wp_error( $response ) ) {
$headers = $response['headers']; // array of http header lines
$body = $response['body']; // use the content
}
<
Wether it will work for you though, is a different story. If both curl and javascript are returning `null`, I don't believe the problem is in the tool used to make the request, but rather what/how you're requesting it.
If your code works everywhere, but does not work on your current host, then you need to speak with your host. Making the same request in a different way is unlikely to help. | stackexchange-wordpress | {

How to trace and resolve a theme problem such as flickering links in WordPress?
When I hover the mouse/cursor over any link on my website the link flickers and it takes some time for the link to be active.
You can see this here ` when you hover over any link on images and text.
I have tried to analyze the code of my theme but couldn't find anything obviously connected to the problem.
Have you any idea how I could solve this? | If you are still interested to look for the reason, here is the CSS code that cause the flickering (which is a CSS related issue).
In the theme's style.css
a:focus, a:hover {
/* ... */
animation-name: fadeIn; /* <=== this cause the flickering, just comment it out or use another CSS to override this such as animation-name: none; */
/* ... */
}
Like @WebElaine mentions, generally if theme has problem, you may consider
* contact the author
* sometimes, maybe there is chance that you might need to overcome the problem immediately before author updating the theme, you may consider to add your own override. You could do it by using child theme and create your own CSS file. | stackexchange-wordpress | {

Send admin an email when a user's search has no results
I'm new to WordPress. What is the easiest way to trigger an email to admin when a user's search has no results. | You haven't provided much info so I will give you a basic example.
You need to find whatever template your theme is using to display the results, possibly search.php. If this isn't your theme create a child theme and duplicate the file that displays the results.
This file should already have an `if` statement for displaying the results, possibly an `if/else`. If not you will need to add one. The Else is used for when there are no results. You can grab what was entered in the search with get_search_query().
Inside the else you can use wp_mail() to send an email.
For Example:
if ( have_posts() ) : while ( have_posts() ) : the_post();
// Code to display your results
else:
// No results so send an email
$query = get_search_query();
$to = '[email protected]';
$subject = 'User Search';
$message = 'User searched ' . $query;
wp_mail($to, $subject, $message );

How to use apiFetch to get author information in Gutenberg properly?

* how you want to design, if this is the first post, does it still have previous class? Some design create loops, first post previous will go to the last post like a loop, some design does not display the previous button if it is the first one.

If I uncheck sections in the screen options GUI, does WP still try to update the associated post meta within that section? | > If I uncheck sections in the screen options GUI, does WP still try to update the associated post meta within that section?
This won't speed up saving, that markup needs to be generated otherwise JS can't show/hide it on the frontend.
On top of that, the data still needs to be saved, but wether that happens is plugin specific. Eitherway this isn't a good route to go down if your saving is slow.
Instead of speculating, actually measure what's happening when you save a post using a plugin such as query monitor, or profiling such as XDebug or XHProfile. You might be surprised by what you find ( e.g. making remote requests is super expensive ). Also consider reducing the number of plugins.

grant multiple roles access to specific admin menu item

I am using the "Members" plugin to create custom user roles if that makes a difference.
Thanks in advance! | You shouldn't use Roles to handle permissions for your menu page. Instead, use capabilities, and then assign those capabilities to whichever roles should have access.
For example, instead of creating a `customrole` role, use a custom capability like `manage_custom_plugin`:
add_menu_page(
'Custom-Plugin',
'Custom-Plugin',
'manage_custom_plugin',
'custom-plugin',
'init_custom_menu_page'
);
Now, using the Members plugin you can enter `manage_custom_plugin` into the "Custom Capability" box, and add it to whichever roles you need.
In code you would grant this capability to roles using `WP_Roles::add_cap()`, like so:
$roles = wp_roles();
$roles->add_cap( 'administrator', 'manage_custom_plugin' );
$roles->add_cap( 'editor', 'manage_custom_plugin' );

3 - check the $table_prefix - make sure the value matches the table that holds the post/pages. (Wordpress uses $table_prefix so you can actually have multiple wordpress installs in the same database.) E.g. $table_prefix = 'wp_'; but your actual table name for posts is `site_posts` \- then that's the problem, they are different sites. If your actual table name is `wp_posts` \- then it is OK.
4 - check your users table. Does the users match what you see in admin panel? If not, the website is not stored in that database.
Let's say the prefix or any of the creds is wrong - just fix it directly in wp_config.php by editing the value to match. It should work right away. | stackexchange-wordpress | {

Is it safe to increase/alter the size of the wp_post.guid column from VARCHAR(255) to VARCHAR(2048)?

Any drawback in increasing to VARCHAR(2048)? Any alternative to make this work without altering the DB?
_Note: as pointed by Tom below, this is a really a limitation of that plugin which should use some other means of storing the external URL..._ | **No, it is not safe** to resize columns in WP core tables, or to alter them.

How to use _embed when using _fields?
It seems that if you use `_fields` in an API request also containing `_embed`, the `_fields` filter will filter out all embeds.
The following request:
domain.com/wp-json/wp/v2/posts?_fields=link,title&_embed=wp:featuredmedia
has no `_embedded` field, but it comes back if I remove the `_fields` filter. I also tried passing `_fields=link,title,_embedded`, but it doesn't work either. | It is not clear in the documentation, but you need to include the "_links" and "_embedded" as fields to be returned. In addition, I include the _embed parameter, as it does not require a value. As of WordPress 5.4, the resources to embed can be limited by passing a list of link relation names to the _embed parameter, though I have not had success with that when using _fields
Example:
domain.com/wp-json/wp/v2/posts?_fields=link,title,featured_media,_links,_embedded&_embed | stackexchange-wordpress | {

str_replace remove words from title
I have a site that reviews movies (DVD/Blu-ray, etc.)So every review in a particular category will have (Blu-ray) after the title, another will have DVD and so forth. i.e. Avengers: Infinity War (Blu-ray).

<?php
echo str_replace("(Blu-ray)"," ","<?php the_title(); ?>");

How to use orderby with meta_query?

'post_type'=> 'post',

Security when outputing wp_oembed_get code
This is a code I have in a function.php action. It is responsible for getting and displaying an embed code. Typically there is a youtube link from $embed_link but it comes from a public form so it can contain anything:

$embed_code = wp_oembed_get( $embed_link[0] );

The list of supported providers is available here. This means the only code that can be output is embed code from those providers.

Buddypress function and global $bp question
I have a question regarding Buddypress tweak.
I can use any Buddypress function when I make a plugin without any include or require functions.
How is it possible? Because Buddypress loads faster than my plugin?
In addition, What does global $bp mean? Withou this global $bp, I can use any buddypress functions, so why does it need?
I'm newbie to development. Thank you :) | Plugins load alphabetically by default. If Buddypress is alphbetically before your plugins folder name, then Buddypress will load first and it's functions will be available. Additionally, whatever functionality depends on another plugins you can always attach to the `plugins_loaded` hook, which fires after all plugins are finished loading. For example:
/**
* Runs code after plugins have finished loading
*
* @return void
*/
function prefix_plugins_loaded() {
die( 'Plugins have finished loading.' );
}
add_action( 'plugins_loaded', 'prefix_plugins_loaded' );
PHP Globals are common in Plugins and WordPress. The `$bp` global is simply a variable that likely holds a required object needed by the specific plugin function. | stackexchange-wordpress | {

How can I remove a button from the paragraph block toolbar?

![remove bold button from toolbar](

* hide the button using CSS
* Add a CSS editor style so that the font weight of bold text is the same as unbolded text

* Users can also write the bold text somewhere else, then copy paste it into the paragraph block | stackexchange-wordpress | {

How to write files in hosting in admin dashboard?
I see that some plugins like Wordfence can write on core folders like `wp-includes` or `wp-admin` (if write permission is enable). In case everything is permitted, is there a way to interact with the hosting from admin dashboard only? Assuming this is on the site installation folder only.
See also:
• Is there a way to figure out the way to access hosting if I have admin privilege? • WordPress file manager plugin that can change file permission? in Software Recommendations | You basically have two options:
1. Use any of the available File Manager plugins for WordPress. Just Google them, literally that phrase I just used.
2. Implement a custom PHP code in your theme or custom plugin which will utilize any of the PHP functions for manipulating the files. For example, check these:
* `file_get_contents()` \- For reading files
* `file_put_contents()` \- For writing files. This will also create a new file if it doesn't exist.
* `unlink()` \- For deleting files
* `chmod()` \- For changing permissions
* `chown()` \- For changing owner
There are also a ton of functions for more advanced file manipulation in PHP. Check this for reference: Filesystem Functions | stackexchange-wordpress | {

How to set default post editor based on role?
I found this code to functions.php

Thanks! | `create_function()` is deprecated as of PHP 7.2.0, so you should avoid using it. Instead, use an anonymous function.
Additionally, it's better the check the current user role _inside_ the callback function, so that the current user role is checked when the filter is applied, not when the hook is added, which could be before the current user role can be determined.
add_filter(
'wp_default_editor',
function( $default_editor ) {
if ( current_user_can( 'editor' ) || current_user_can( 'author' ) ) {
$default_editor = 'html';

One file for all translations
Is there any solution to translate just specific strings from plugins/theme from one central file? So the only translated strings are there (frontend) so editor of the website doesn't need to search trough all .MO files in Loco translate for example? | **No, this isn't possible, that's not how`mo` or `po` files work.**
A `po` file declares which locale it is for, and gets compiled into an `mo` file. You can't store more than 1 locale in the same file. Each file represents a single locale.
Keep in mind that these files aren't a WordPress thing. They're a `gettext` thing, and are used in lots of different applications, including other CMS's and even programs that have nothing to do with websites and servers.

Rewrite URL for only archive page (custom post type)
There is a few Q/A about custom post URL rewrite but I haven't found any simple answer to what I'm trying to achieve.

* `siteurl.com/agenda`
* `siteurl.com/event/event-slug`
Right now in my theme I use two files `single-event.php` and `page-agenda.php`. The latter is the archive page, because I want my archive post slug to be `siteurl.com/agenda` and not `siteurl.com/event` so I've created an additional page on my backend.
It's working like that but I'd like to know if there is a more elegant solution to only rewrite my CPT archive page URL while using the proper `archive-event.php` template? | You can have a separate slug for the post type archive by setting the slug as the value for the `has_archive` argument, instead of just `true`:
register_post_type(
'event',
array(
'has_archive' => 'agenda',
// etc.
)
);
Now you can use `single-event.php` and `archive-event.php` for the single and archive views, but the URL for the archive will be `siteurl.com/agenda`. | stackexchange-wordpress | {

Do not change the order of the tags in the editor
I have a list posts by tag, but the relation is not relevant because first look for the posts with the first tags stored alphabetically, and not the first main tag, that is to say for me the order of the tags are key because the first tag is the most relevant. So when saving everything, it is sorted alphabetically and this does not help me, any idea how to alter this?
![screenshot]( | **Terms/Tags aren't ordered**.
To help make the terms easier to read, the editor will list them alphabetically, but that isn't because they're ordered alphabetically in the database. It's because a piece of javascript sorted the terms in the UI control.
There is no order, only the order you give them. Fundamentally terms have no order. Any order you see in the editor is purely circumstantial, there is no order mechanism in the database for terms.
If you want to give special meaning to a term, you need to do so explicitly, e.g. store the term ID of the significant term in post meta. You cannot rely on order, as terms do not have order. | stackexchange-wordpress | {
