503 Login WordPress
Anyone have experience failed to login and got the 503 Service Unvailable?
My WP site hosted on GoDaddy Managed Hosting. They said cause of this is came from the WooCommerce. I tried to disable this but the error still occured.
Thanks | I've had 503 errors when using shared hosting services with Fasthosts / Rackspace etc. Typically, they don't last long, but if yours are - then there is something going on with the server you are sharing. You might want to check that the memory limit in the config is 96 MB but that shouldn't be causing the issue. | stackexchange-wordpress | {

Override css rules of a plugin within my own theme
I want to override some rules of a plugin css file within my own theme so next time that I updated that plugin, my settings of that plugin be in a safe place . currently I copied that css file into my theme and changed some rules.So then I need to override this rules. I think found an answer that is related to my question (HERE) but I can't understand this code. how it works?
add_filter( 'style_loader_src', 'wpse106104_replace_stylesheet', 10, 2 );
function wpse106104_replace_stylesheet( $stylesheet_src, $handle ){
if( 'plugin-script-handle' == $handle ){
$stylesheet_src = get_template_directory_uri() . '/css/themes-copy-of-plugin.css';
}
return $stylesheet_src;
} | The `style_loader_src` filter is used to modify/filter the src (url) of a stylesheet. The function callback accepts two parameters, the first is the original src and the second the handler of the stylesheet. The handler is the first parameter of `wp_enqueue_style()` used to enqueue the stylesheet.
So, to replace a stylsheet source with another one you should check the handler to know wchich stylesheet it must replaced, in the code you posted the checked handler is `plugin-script-handle`. | stackexchange-wordpress | {

Adding a menu item for a Custom Post Archive
I've created a Custom Post type (`project`) and it works perfectly. I have a custom archive page (`archive-project.php`), and that works great, too, but what's the best way to add a link to that custom post archive in the site's primary menu?
I've created a Custom Link (see below), but is there a better way that isn't so hard coded?
![enter image description here]( | You can use a built in function of the menu editor for this. Go to your Custom Post Type in the Menu editor, click the "view all" tab and the first item you see is a link to the CPT archive page.

Check if a database is well installed
I tried to install wordpress under `eclipse` and `xampp` under ubuntu. I created the database (user: `root`, password: empty) by a sql command `create database wordpress;`, that is it.
The wordpress seems to work, because I can run and see that with `locallost` under a browser.
Then, I tried to install another wordpress projet (which works) that my colleague had already customised. He sent me all the wordpress files and a database file `asyc.sql`. I created another projet under eclipse and imported the database by the following command line:
`/opt/lampp/bin/mysql -u wpuser -p wpuser asyc < asyc.sql`
And here is the result:

The database `asyc` does not seem to be well installed, though `wp-config.php` is well set in my opinion:

woocommerce blank page after clicking add to cart
I am building a custom plugin based on woocommerce. As a part of this development I have added few custom fields to single product page at `woocommerce_before_add_to_cart_button` hook.

As soon as I click on Add to Cart button I am seeing a blank page whose URL in address bar is same as that product page, may be the redirection to cart is no happening. When I go directly to the cart page to verify , I am able to see the added product in cart.

how to prevent all css and javascripts files from loading

global $wp_styles;
$wp_scripts->queue = array();
$wp_styles->queue = array();
return;
}
add_action('wp_head', 'prefix_block_resources');

What are the issues associated with upgrading MySQL for Wordpress?
What are the issues associated with upgrading MySQL from 5.1 up to 5.5 for a server hosting multiple Wordpress sites?
Will there be problems with the database after the upgrade?
I have Plesk 12 installed on a Ubuntu server and I can update to the latest version of MySQL (I believe only 5.5) but I don't know if this will cause issues? Is upgrading MySQL straightforward in terms of database compatibility (upgrading 5.1 to 5.5) or is it likely that things will break? | It depends on what version of WordPress your sites run. If you are up to date, you shouldn't have much of an issue. According to the official WordPress hosting guide, any version of MySQL version 5.0.15 or greater is supported for WordPress. You can give this article a read and see if there is anything that jumps out at you as being particularly dangerous.
If you are running a version of WordPress that is very old you are more likely to run into issues; however, if you are running a version that old you should strongly consider upgrading WordPress regardless.
That said, there can always be issues with this type of upgrade and if you decided to go forward with it you should make sure you have backups of everything. If WordPress compatibility is your only concern you should be ok. If this is for a production environment, I would strongly suggest testing both the upgrade and your sites on a dev server rather than doing a live in-place upgrade. | stackexchange-wordpress | {

Making sub-menus exclusive

1. Animals

User can manage one page accessible by everyone?
I'm creating a local site for my community. On this site we feature tutors in the area for hire.

Referring to site URL in shortcode argument
Apologies for the noob question -- have searched extensively, and it's probably a forehead-slapper.
A plugin I'm using offers a shortcode that takes a URL as an argument; I should set that argument to the URL of a particular page on my site. For example:
[cool-shortcode arg_needing_URL="URL of site page goes here"]
How can I avoid hardcoding the URL? I'm working on localhost for the moment, but I'd like the argument to work no matter where the code is hosted. I could tinker with the PHP for the shortcode to allow a special argument syntax meaning "look up this constant," but that feels like using a chainsaw to open an envelope. Does WP have a syntax for referring to constants from your content? | To answer the heart of your question: no, WordPress does not have a way of referencing posts by ID/slug/etc. within the post content. In fact, probably the recommended way to do that is with a...shortcode! Even that wouldn't help you in this case, though, since you can't nest shortcodes without a plugin.
So I'd recommend you use your own shortcode, or plug theirs if it's a pluggable function. Simply replacing their URL argument with a `get_permalink()` that accepts an ID from the shortcode is probably all that's required. | stackexchange-wordpress | {

Can you check if a post WYSIWYG field has an image in it?

For example, if I upload an image into the editor and float if right of the text - I intend on treating the rendered container differently than a container without the image. | There isn't really a built-in way in WordPress to determine if a content field _has_ an image in it, but you can use standard PHP functions to check.

You haven't included any of your code, so this is just a sample you'll need to work in to what you already have.
The `strpos()` function will tell you if a specific string is inside another string. For example:
if( strpos( get_the_content(), '<img ' ) ){ /* this content has an image */ }
You could perhaps use this to add classes to your content container, so you can treat it differently in the CSS:

$image_class = strpos( get_the_content(), '<img ' ) ) ? 'has-image' : 'no-image';

Getting error Parse error: syntax error, unexpected 'add_filter' (T_STRING), expecting function (T_FUNCTION)
I am getting error

First you need to call it from where code makes sense, _inside_ another class method or from outside a class.
Second you cannot hook methods by their name alone, you need to use proper callback with a name of the class. Examples would be `[ __CLASS__, 'method_name' ]` (static method) or `[ $this, 'method_name' ]` (non-static method in class instance).

Is /wp-login.php?redirect_to[] exploitable?
I have a wordpress site, against which I ran a penetration testing tool (debug mode was on at the time)
It reported a (medium severity) issue in that errors were being displayed, and cited
> `/wp-login.php?redirect_to[]=blah`
>
> as triggering a warning: `urlencode()` expects parameter 1 to be string, array given in `/home3/.../wp-includes/general-template.php` on line 340
When I turned debug mode off, and replayed the session the redirect took place, and redirected me to /Array
Which concerns me that wordpress may be trying to evaluate the querystring parameter name in some way that is exploitable.
Am I being overly paranoid? | I think this is nothing to worry about.
The redirect target is sanitized and validated a lot. To be honest I think I haven't seen any part of the WordPress code where so many checks happen for the most obscure attack vectors.
Finally when you cast an array to a string `Array` is returned which is what you've seen.
> Arrays are always converted to the string "Array";

Can a plugin still effect a site even after deletion?
I haven't been able to find an answer on whether or not this can happen. If there is a poorly built plugin that hasn't been updated in two years, and I make the poor decision to install it anyway - is it possible that even after complete deletion in the FTP this plugin could still be effecting my site? Has anyone ever dealt with something like this before and how did you fix it? I imagine I might have to check out the database if the plugin is causing this funky behavior, but I'm not sure where to start to rule this out. | Yes, a plugin that does not properly clean up after itself can continue to affect your site even after deletion.

Handling single.php in Multisite
I'm using sub directories for my WordPress multisite, posts are controlled with single.php. How can instruct single.php to use a different header and footer file for the site in the sub directory?
I tried using get_current_blog_id but that didn't seem to work. For example:
$current_blog = get_current_blog_id();
if ($current_blog == 2) {
get_template_part('header', 'blog2');
} else {
get_header();
}
**Edit**
I was able to use in_category so this is my solution for now:
if (in_category('News')) {
get_template_part('header', 'blog2');
} else {
get_header();
} | I'm surprised `get_current_blog_id()` didn't work, since that's probably the best way to approach it. Always try doing a `var_dump( $current_blog )` to make sure you're testing for what you need. _Edit (19 Aug 2015): Also, triple check that you know which header you're expecting to see and that you're making the change you want in the right header file._
Alternately, consider making a child theme and replacing the header that way. That may be more maintainable over the long run, particularly if you plan on using unique headers for other sites.
Also, you can use `get_header( 'blog2' )` instead of `get_template_part( 'header', 'blog2' )`. Same result but the first way's a bit cleaner. | stackexchange-wordpress | {

RewriteRule ^$ /my-articles [R=301,L]

Wordpress Redirecting Non Category Pages /page/nnn to their Canonical URLs
I seemingly to have a strange issue I have found in almost every other Wordpress site.
Suppose, you have set your Blog home to a static WP page `/myhome`. And you have a separate page for blog `/blog`.
Now, this works fine and should be:
/blog
/blog/page/2
/blog/page/3
/blog/page/4
But, for all other pages, e.g. `/about-us`, these links also work:
/about-us/page/2
/about-us/page/3
/about-us/page/4
And show the content of the `/about-us` page.
My problem is that `/about-us/page/2` should ideally redirect to `/about-us` (it's canonical URL) since there are no paginations in any other page except the `/blog`.
What am I missing there ? This seems to happen on almost all sites I have checked and is really frustrating from SEO point of view. | This is by design and intentional. WordPress rewrites have become increasingly complex over the years, and many plugins utilise the `page` endpoint for a page (usually with a template and custom query) - redirecting introduces a potential world of pain.
Long story short, it doesn't matter anyway. WordPress adds `<link rel="canonical />` for pages, so no need to worry over duplicate content.
**Update:** For localised situations where you want to disregard the potential risks, this will canonicalize all page URLS - note that it does not check if a page is actually paginated (i.e. with the `<!--nextpage-->` quicktag) and will break this feature if you use it.
function wpse_199180_canonical_pages( $wp ) {
if ( ! is_admin() && is_page() && isset( $wp->query_vars['paged'] ) ) {
wp_redirect( get_permalink( get_queried_object() ), 301 );
exit;

WordPress Admin Email

Disable user registration password email
So, WordPress 4.3 has a new password system as we all know. Unfortunately, this new system has done away with the ability to **NOT** send new users an email.

Jetpack JSON API configure button not showing
Installed fresh WP on my Hostgator - shared host plan. Installed Jetpack, connected to wordpress but can't make the JSON API to work. After activating there's no Configure button just deactivate button and i'm stuck. Thank you | You don't need to configure anything. As soon as you connect Jetpack to your WordPress.com account and activate the JSON API module, you'll be able to to use the API. You can double check that by running some test queries using the REST API Console here. You could also just try to load one of the endpoints in your browser, like so.
If you're still having issues working with Jetpack's REST API, I'd suggest contacting the Jetpack support team through this form, or in the Jetpack support forums. As mentioned in on-topic, it's best to use appropriate support channels for third party plugins and themes. | stackexchange-wordpress | {

Using ACF Custom Field value in a URL with do_shortcode()
I am using the ACF custom fields and video.js plugins and I want to add the custom field value inside the url for the youtube video that is inside of `do_shortcode()`
So far this is what I've come up with but it doesn't seem to work:
<?php
$thevideo = the_field('video');
echo do_shortcode('[videojs class="youtubevideo" youtube=" . $thevideo . '"]');
?> | Simply you need to replace `the_field('video')` with `get_field('video')`.
**Why?**
Because according to ACF documentation;
`get_field($field_name, $post_id, $format_value)`
> Returns the value of the specified field.
Whereas on the other hand
`the_field($field_name, $post_id)`
> Displays the value of the specified field. (this is the same as “echo get_field($field_name)”)

URL rewrite before template_redirect called
**Logic**
* I have a page template at `/blog` that contains a "public" blog.
* I have a page template at `/members` that is members area.
If a user enters the URL `/members/blog` I want to catch this in the `template_redirect` hook and load up a custom template that shows a "private" blog
**Problem**
Before `template_redirect` is called `/members/blog` is re-written to `/blog` so I can't load the private blog page.
There is nothing in the rewrite rules that says to do this. | So the problem was `redirect_guess_404_permalink` was detecting a 404 error and 'guessed' `/members/blog` to be `/blog`
My hacky solution was to hook into the status error check (Stop Wordpress from "guessing" redirects for nonexistent URLs) and if URL parts match then unset the guessed solution
function blog_no_redirect_guess_404_permalink( $header ){
global $wp_query;
if( is_404() ) {
// Get Request URL Parts
$url = parse_url($_SERVER['REQUEST_URI']);

Tweak next_post_link for it to include thumbnail

How to disable Wordpress blog folder
I've integrated Wordpress into my existing website and used WP JSON API to get the content from WordPress, but I don't want the WordPress itself to be available to my viewers.
When I refresh my website (`myWebsite.com/blog`), it appends a slash (`/`) and goes to `myWebsite.com/blog/`, which goes to the WordPress website itself and does not show mine.
How can I make sure that it does not append a slash to the URL and does not go to the WordPress theme when I refresh the page? | To clarify, `/blog` and `/blog/` are the same. The slash is added by the browser to properly structure the URL (best way I can explain it).
Your're trying to access two different pages with the `/blog/` slug. In this case, WordPress is overriding the blog link from your existing website and showing content from there.
What you'll need to do is set your WordPress site to a different location other than `/blog/`, such as:
`myWebsite.com/wordpress/`
Then, you will want to prevent unauthorized access to your WordPress site if someone got ahold of the link. You can use a simple plugin such as Force Login which require visitors to log in order to interact with the website. | stackexchange-wordpress | {

How many queries are normal to execute on a WP site?
I use the following PHP code in my theme's footer.
<?php echo get_num_queries(); ?> queries in <?php timer_stop(1); ?> seconds.
Then I realized that about 140 to 210 queries are executed for each page. Is it normal or not? I use a caching plugin, does it help?
I'm using a shared hosting and _sometimes_ (not always) I get about 20 visitors in a second. | I wouldn't say it's not "normal", but it's above typical.
The common minimum of queries would go like:
* main query (set of posts)
* functionality (menus, widgets, etc)
* data (terms and such)
On a WP test data that would make something under 50 queries on home page. With object cache it will fall under 10 on repeat visits.
Without knowing your set up — yes, it is likely that you are requesting too many things and/or not caching results optimally.
However some sites _need_ to query a lot of things to, well, perform their function.
Roughly I would recommend to:
* dump queries and examine _what_ are they (Query Monitor plugin would be a start)
* add Object Cache back-end to server, see if it makes a difference (but it's a good idea to have in _any_ case)
* consider manual or semi-automated caching for code which makes queries (full page and/or fragment cache) | stackexchange-wordpress | {

Wordpress mysql table double prefixes
Currently working on updating a wordpress website for a client of mine. The wordpress mysql database has double prefixes in it though.
The standard wp_ prefix and her own custom prefix for the tables. The custom prefix is currently being used. The wordpress install seems generator by installatron. Is it safe to remove all the wp_ prefixed tables or does wordpress still use those? | 1) In order to check what kind of prefix used by current installantion you can goto `wp-config.php` in a root directory and find line with `$table_prefix = 'PREFIX_HERE'`; variable
2) Backup the DB before making any action!
3) Additionally check if other tables with different prefixes/name_patters are not used by badly-written 3rd party plugins. They may not follow a good-practice:
> Do not hardcode the WordPress database table prefix (usually "wp_") into your Plugins. Be sure to use the $wpdb->prefix variable instead.
4) Right after this done you can drop all tables using a UI mysql admin panel or using more advanced way:
a. Generate a DELETE query programmaticaly:
SELECT CONCAT( 'DROP TABLE ', GROUP_CONCAT(table_name) , ';' )
AS statement FROM information_schema.tables
WHERE table_schema = 'YOUR_TABLE_NAME' AND table_name LIKE 'WORDPRESS-PREFIX_%';

Save values generated via API as taxonomy terms

//...

Wordpress 4.3 broke meta redirect (with url params plugin)
I'm using the plugin URL Params (homepage) in order to send an URL to a page and after three seconds redirect the user to that page. Unfortunately Wordpress 4.3 broke that functionality.
This is how it was done:
<META HTTP-EQUIV="Refresh" CONTENT="3; URL=[urlparam param="link"]">
The redirect only redirects the user to <
A work around is putting a link and placing it like this but then I loose the auto redirect.
<a href='[urlparam param="link"]'>
Does anyone know how to rewrite the meta tag so that the redirect could work? | You need to allow the content attribute of a meta tag to contain a shortcode, eg in your "functions.php" add:
add_filter( 'wp_kses_allowed_html', function ( $allowedposttags, $context ) {
if ( $context == 'post' ) {
$allowedposttags['meta']['content'] = 1;
}
return $allowedposttags;
}, 10, 2 );
and then your original **(without the quotes in`param=link`)**
<META HTTP-EQUIV="Refresh" CONTENT="3; URL=[urlparam param=link]">
should work. | stackexchange-wordpress | {

reply to comment excerpt instead of author in comment title
One can reply to a comment using `Reply` link, below each comment item in comments list.
According to codex, by clicking that link and using `comment_form_title` function like this:
$replytext = 'Leave a Reply to %s'; // %s = author
comment_form_title( $noreplytext, $replytext, $linktoparent );
You can have a comment form title as `Leave a Reply to [author's name]`.
I would like to find a way in which you have this output instead:
**Leave a Reply to [comment's excerpt]**
where comment's excerpt is the comment's first few words. | Finally I found a way and I am posting it here to address any further requests for such a workaround.
You may add a customized version of `comment_form_title` function to your theme's `functions.php` file and call it in your theme's `comments.php` file.
function my_comment_form_title( $linktoparent = true ){
global $comment;
$noreplytext = __( 'Leave a Reply' );

insert_with_markers() WordPress & htaccess help
I'm trying to develop a plugin which adds a single line to the .htaccess file generated by WordPress.
The problem is that one of the WP generated lines override my rule, and via the "insert_with_markers()" function, I have not found a way to specify a position so I could prepend my line instead of appending it as currently is happening.
The first line of code is the auto generated WordPress line, and the second one is the one I'd like to have working.
RewriteRule . /dev/index.php [L]
RewriteRule ^article/([/_0-9a-zA-Z-]+)$ [R=301,L,NC]
The way I see it there's 2 possibilities here:
A) Somehow specify where the insert_with_markers() places the new line of code, or
B) Modify my RewriteRule to work together with the WordPress generated one.
I hope you can point me a step or two closer to the right path.

New User ID not working in custom function with user_register hook

Getting "too many redirects" when using wp_redirect for attachment page
Code comes from the codex:
<?php wp_redirect( get_permalink( $post->post_parent )); exit; ?>
I added the above, in an empty attachment.php page. When I visit an attachment page (eg. < I get the error:
"This webpage has a redirect loop ERR_TOO_MANY_REDIRECTS"

UPDATE:
Based on the answer given, I updated my code to:
if($post->post_parent != 0):
wp_redirect(get_permalink($post->post_parent));
else:
wp_redirect(get_permalink(2));
endif;
exit;
That way if the post_parent == 0, it will go back to the home page. I don't know if I should be catching for anything else. But this seems to work.
Thanks Ignat B. for explaining what was going on. I have a few attachments that have post_parent = 0. And it just happened that the link I was trying out was one of them. | Considering WordPress Codex, and WordPress Template Hierarchy \- attachments stores as post records.
Your code is making a loop redirection to the same page. The most reasonable case is:

When can you get current page ID and initialize hooks right after?
I'm developing a plugin and need to know on what page user is and then add specific hooks and filters for that page.
And my problem is that `is_page()` and `the_ID()` doesn't work outside of `wp`, `wp_loaded`, `init` actions, but if i use these actions then i can't initialize hooks because for them to work properly they must be added before those actions.
So my question being, is there any hook from witch i can call `the_ID()`, get a proper result **and then** add another hooks for that page? Or is it possible **only** using PHP's `$_SERVER['REQUEST_URI']`? | The earliest safe hook to get post information is the `template_redirect` hook. All the hooks in question runs before Wordpress has setup postdata, so any post info are still unavailable at that point.
The globals like `$wp_query` and `$post` will still contain no data, that is why your efforts returns nothing.
## EDIT
Extra info as per comment by @TheDeadMedic
> Actually `wp` is an earlier, still-safe hook - just make sure to use `get_queried_object()` instead of relying on `$post` global | stackexchange-wordpress | {

Adding HTML within an image title attribute

<img src="img.png" title="<h1>Title heading</h1><hr><h2>Title sub heading</h2>" | First of all i'd recommend you stop using `title` attribute for html container purpose:

In FireFox and Opera it pops up when you hover over an image
In order to get things works you can use `data-` attribute (very good "intermediate" article about data-attribute with example how to use)

Why would media_sideload_image() not work locally?
I designed a theme for a client that sideloads an image returned from an API. It has always worked and it's still working on their live website.
My staging environment _used_ to be a separate account on the same server. It was accessible online but password-protected and sideloading images always worked there as well. Today I created a local staging environment using VirtualHostX. Everything on the website works as expected, _but sideloading doesn't._
* Nothing in my source has changed.
* The WordPress installation is a direct clone (configuration and build numbers are identical)
* I've verified that my AJAX response is returning an image URL, but the image doesn't even make it into the media library.
