Error:406 not acceptable
I have a wodpress site, and I have submitted it to google webmaster tools. When I search on google by my site name, the results come, and on clicking the searched result, I can open the website on my PC. But when doing the same thing on my mobile, i get this
Error 406: Not accebtable
How can can resolve it? | I had a similar problem recently with this 406 Not Acceptable error occurring when trying to update permalinks in WordPress. I also had the same problem when submitting any changes to the editor, etc. Google Webmaster tools would yield the same result.
The solution is to disable the mod_security firewall within your `.htaccess` file.
My fix was to install a plugin called "WP Htaccess Editor" (free WP plugin), then update the `.htaccess` file to the following, between the "Begin WordPress" and "End WordPress" tags:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

Prevent registration except through form
I have a Formidable Pro form that handles user registrations on my site. It has a CAPTCHA. Is it possible to prevent anyone from registering by other methods (e.g. wp-register.php)?
(I've tried using plugins to stop spam registrations but there was always something that didn't quite work for me. If the CAPTCHA is enough, why complicate things by adding a new plugin?) | I found a good answer and slightly modified it on a related question . It uses htaccess, and redirects any requests to wp-login.php?action=register.
# BLOCK SPAM REGISTRATION REQUESTS (wp-login.php?action=register)
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{THE_REQUEST} ^.*(wp-login.php\?action=register).* [NC]
RewriteRule ^(.*)$
</IfModule>
Notes:
1. In the answer I linked to he totally blocked these requests. However I have redirected them to the Formidable Pro signup form, as you can see in the RewriteRule.
2. As far as I know, all regsitration attempts, even wp-register.php, will go through wp-login.php?action=register.
3. I have tested signup using my Formidable Form and it's still working fine. Also, wp-login.php, including lost password, is still working. | stackexchange-wordpress | {

Redirect homepage /page/1/ to /blog/page/1/

meta_query 'compare' => 'IN' not working
First of all, I know it's a duplicate, but none of the older answers were helpful.
I'm searching in posts through `post_meta`. Here's my code, which currently returns nothing.
$args = array(
'numberposts' => -1,
'post_type' => 'post',
'meta_query' => array(
array(
'key' => 'system_power_supply',
'value' => array('single', 'redundant'),
'compare' => 'IN',
)
)
);
$query = new WP_Query($args);
echo $query->found_posts;
If I remove `meta_query` it works. I'm sure of these things:
* There's no spelling mistake in the `key` or the `value`.
* post type is `post`
* There **is** a post with the value 'single' in 'system_power_supply'. However, post fields are generated by Advanced Custom Fields. | There's no easy way to search serialized values in a meta query. If the list of values isn't crazy long, potentially you could set up multiple meta queries:
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'system_power_supply',
'value' => 'single',
'compare' => 'LIKE',
),
array(
'key' => 'system_power_supply',
'value' => 'redundant',
'compare' => 'LIKE',
)
)
Or if you wanted to get super fancy, you could set it up dynamically:
$values_to_search = array('single', 'redundant');
$meta_query = array('relation' => 'OR');
foreach ($values_to_search as $value) {
$meta_query[] = array(
'key' => 'system_power_supply',
'value' => $value,
'compare' => 'LIKE',

Adding "reply-to" in the email
So, I am trying to add "reply-to" in the order email using the `billing_email`
Here is what I have so far but the code is not written well and I am not sure how to change it.
Here is the original:
public function send( $to, $subject, $message, $headers = "Content-Type: text/html\r\n", $attachments = "" ) {
$email = new WC_Email();
$email->send( $to, $subject, $message, $headers, $attachments );
}
Then I edited to the following:
public function send( $to, $subject, $message, $attachments = "", $order ) {
$headers = array( "Reply-To: <?php echo $order->billing_email; ?>" );
$email = new WC_Email();
$email->send( $to, $subject, $message, $headers, $attachments );
}
Any suggestions?
Thanks | Not sure what the `WC_Email` class does exactly, but if the `$headers` argument is an array of headers, then you're almost there. To interpolate a variable value into a string in PHP you don't have to do the `<?php ...` stuff because it'll be rendered as is. Instead, you can use:
$headers = array( "Reply-To: {$order->billing_email}" );
Or:
$headers = array( 'Reply-To: ' . $order->billing_email );
Or:
$headers = array( sprintf( 'Reply-To: %s', $order->billing_email ) );
Also, if the billing e-mail address is user input, don't forget to validate it with `is_email()` and/or sanitize it with `sanitize_email()`.

With two custom post types, how to make one a child of the other in the admin menu?
Been following Justin Tadlock's nice clear tutorial on how to have one custom post type act as a dropdown for another in the admin edit screen.
His example is of a restaurant CPT needing a dropdown to a neighbourhood CPT (btw, as the author points out in the comments, the reason not to just use a taxonomy is that the neighbourhood could have a bunch of custom fields not catered for by the built in taxonomy).
Here's the screenshot:
!enter image description here
The tutorial code works perfectly on our site.
My question is, to keep the admin menu clean it would be nice to have everything sit under one root entry like so:
Places
- Add New
- Neighbourhoods
I only know how to add a root level CPT. So mine looks like this:
Places
- Add New
Neighbourhoods
- Add New | In your `register_post_type` call, use the argument `show_in_menu`:
register_post_type(
'neighbourhood',
array(
'show_in_menu' => 'edit.php?post_type=place',

Can someone show me to give authors 'just' the ability to embed and iframe in posts? | The capability you are after is called `unfiltered_html`. Some options:
1. Modify **author** capabilities in your theme `functions.php`. This is saved in the DB, so you can access a page, make sure it works then remove it from your `functions.php` file. A better option would be to run it on theme activation. See this page on WP Codex for options:
function add_theme_caps() {
// gets the author role
$role = get_role( 'author' );
// This only works, because it accesses the class instance.
// would allow the author to edit others' posts for current theme only
$role->add_cap( 'unfiltered_html' );

Remove / overwrite some functions in buddypress.js
What's the best practice to overwrite some JS-functions in buddypress.js?
There are some quite annoying things in there like animating the form-fields on click/blur/post which I need to remove because they absolutely don't fit our design.

But if you place a buddypress.js in `wp-content/themes/your-theme/buddypress/js/` this file will be taken instead. The handle will be `bp-parent-js`

Writing editor content to a file
I have a project I'm working on where I need to write the content of the post editor to a physical file on the web server when a post is saved or updated.

Is there a different way I should be going about this and/or is there something I'm missing?

function pht_write_file() {
$file = WP_PLUGIN_DIR."/myplugin/test.xml";
$content = get_the_content();
file_put_contents($file, $content);
}
add_action('publish_post', 'pht_write_file'); | You should hook `save_post` instead of `publish_post`. `publish_post` only runs when a post is initially published and won't catch subsequent saves.
Additionally, the `publish_post` hook passes parameters to your function and those should be used to retrieve info about the post being published rather `get_the_content()`, which only works when you're inside the loop.
I think you're looking for something like this:
function pht_write_file($post_id){
if(get_post_status($post_id) !== 'publish') return; //only run if post is published
$post = get_post($post_id);
$content = $post->post_content;
$file = WP_PLUGIN_DIR."/myplugin/test.xml";
}

Prevent Version URL Parameter (?ver=X.X.X) on Enqueued Styles & Scripts
## Use Case
I've been experimenting with Chrome's Dev Tools Workspace features. It includes the ability to edit a file directly in Dev Tools and have the saved stylesheet refresh itself (or even compile and then refresh!).
However, as documented in the StackOverflow question "Chrome's “Auto-Reload Generated CSS” not reloading page when SASS recompiles CSS", URL parameters on the stylesheet URL prevent Chrome from noticing the change.
## Desired Outcome
That means that **only during development** , I wanted to remove the `?ver=X.X.X` from the normal stylesheet `<link>` output by `wp_enqueue_style()`. In other words, I wanted the default `href`:
to instead be this:
| ## Default `wp_enqueue_[style/script]()` behavior
The default value for the `$version` argument of `wp_enqueue_style()` is `false`. However, that default just means that the stylesheets are given the _WordPress version_ instead.
## Solution
Thanks to "Remove version from WordPress enqueued CSS and JS", I learned the undocumented fact that passing in `null` as a version will remove the version altogether!
## Example
wp_enqueue_style( 'wpse-styles', get_template_directory_uri() . '/style.css', array(), null );
## Caveat Reminder
It's worth pointing out, as noted in the question, that this should probably only be done during development (as in the specific usecase). The version parameter helps with caching (and not caching) for site visitors and so probably should be left alone in 99% of cases. | stackexchange-wordpress | {

As a general rule yes – all cached pages (unless a user is logged in, when pages aren't normally cached) would typically be served by your cache plugin (or an advanced tool like Varnish) as if they were a static HTML file.
It's not just about the server speed, you can make a lot of difference by optimising your image sizes, reducing the number of HTTP requests, writing more efficiently javascript or CSS and so on.

How to write specific HTML code with a specific custom field?
In my Wordpress, each post can contains 2 buttons pointing to different links.
To make it easy for the end user, I want to create a couple of **Custom Fields** where the user only needs to enter the **URL of the link for Button A or Button B** (or both), but once inserted, it will actually write the following code inside the post:
<a href='Custom Field A Value' target='_blank' class='btn btn-primary fb-event'></a>
<a href='Custom Field B Value' target='_blank' class='btn btn-primary ra-event'></a>
That would be if both custom fields are filled and inserted, it can also include only one link.
So long story short, can I hardcode HTML code around specific Custom Fields and use the value inside the HTML?
Is that even possible? | Try this :
// get_the_ID() will work if you're running within The Loop.
$fieldA = get_post_meta( get_the_ID(), 'name_of_fieldA', true );

if( $fieldA ) {
echo "<a href='".$fieldA."' target='_blank' class='btn btn-primary fb-event'></a>";

How can I debug the TTFB in WP?
I'm developing a WP theme, based on _s default theme with WP 4.1.1.
I keep getting a TTFB(time to first byte) of 22s, consistently both on the front and back of the site, while on localhost.
Here's a print from DevTools: !enter image description here
I'm using the Debug Bar plugin, so I can see on the Queries and Profiler tabs that this is not a database or execution time problem(the sum of both takes 700ms). I guess it's not a rewrite problem either, since it behaves the same on the default permalink structure.
Other wordpress sites on my www don't have the same problem, so I'm discarding the server configuration. I also tried to load in incognito mode, without any difference.
Is there a way to debug this a little deeper? | Meanwhile, I found some plugins and tools that can help with this:

* Laps
* Debug Bar with some add-ons(Slow Actions, Rewrite Rules, etc.)

Add attribute to shortcode dynamically
I'm looking to add an attribute to a shortcode used in a post dynamically. For example, say we start with:
[shortcode-name]
I'd like to add the "attribute=xxx" portion to the shortcode so it is effectively like so:
[shortcode-name attribute=xxx]
For just the first shortcode encountered in a post. Is this possible?
Thanks! | Untested (and can't test right now) but you ought to be able to add attributes with a filter... something like:
function test_sc($atts,$content) {
// echo 'test_sc';
$atts = shortcode_atts(
array(
'foo' => 'no foo',
'bar' => 'default bar',
),
$atts,
'testsc'
);
// var_dump($atts);
}
add_shortcode('testsc','test_sc');
function test_shortcode_att_add($atts) {
# this filter should only run once (first use on page)
remove_filter('shortcode_atts_testsc','test_shortcode_att_add');
$atts['xxx'] = 'yyy';
return $atts;
}
add_filter('shortcode_atts_testsc','test_shortcode_att_add');

How to add an attribute to a user?
I have looked for an answer, and couldn't find a clear and relevant answer yet.
I want to add more attribute to the users not to display, but only store information about them. The information will be used for a background function. I know that usermeta is used to add more attributes, and I know how to access the already existing information, but I don't know how to add/create new attributes.
This piece of information can be a null string by default for every user and modified if the user enters information.
I'd appreciate any kind of help since I'm new at Wordpress. Thanks! | The easiest trick is to use the `user_contactmethods` \- the fields don't actually have to be contacts, but WordPress will do all the leg work for you (displaying the fields & saving the data):
function wpse_183763_user_contactmethods( $methods, $user ) {
$methods['my_field_1'] = 'My Label For Field 1';
$methods['my_field_2'] = 'My Label For Field 2';
return $methods;
}
add_filter( 'user_contactmethods', 'wpse_183763_user_contactmethods', 10, 2 );
If you add this code to a plugin or your `functions.php`, you'll see the new fields when editing your profile. To get the values, just use the meta API:
// With a user ID
echo get_user_meta( $user_id, 'my_field_1', true );

$html = str_ireplace( '<a ', '<a itemprop="replyToUrl" ', $html );

Meta Slider Lite plugin shortcode in post not working
I'm trying to implement a slider in my Wordpress post. For this I'm using `Meta Slider` plugin. When I've added a slider, I should be able to use the shortcode in my posts (`[metaslider id=21]`). If I add this to one of my post, it shows up the same way on the live page. I don't see any slider, there is just a string "[metaslider id=21]" on my page.
I checked that `wp_footer();` is implemented right before the `body` tag is ending and that the footer is implemented in every php file.
I get the post content using this way:
$args = array('posts_per_page' => 5, 'tag' => get_the_title());
$wp_query = new WP_Query( $args );
$posts = $wp_query->get_posts();
foreach($posts as $post){
$id = $post->ID;
$content = get_post($id);
echo $content->post_content;
}

Redirect Every Instance of The Author Template Pages to Custom Author Pages

Check if sidebar is rendered?

if ( ! is_active_sidebar() ) {
// Add something here perhaps?

}

Understanding the Template hierarchy
I've got a template called `News`.
When I go to the Dashboard and edit the Page called `News` which has a web address of `news.html` I can see it uses this template (i.e. in the Page Attributes > Template section).
However, if I then update the Template Name (i.e. in `page-news.php`) to something like `NewsTest` and refresh the News Page in the Dashboard I see that WordPress has updated the Template being used in the Page Attributes > Template section.
Here's another more specific example:
If I then edit the slug to `newsaaa` and the template name to `Newsbbb` it still shows up in the Page Attributes > Template section.
I have been working my way through the Template Hierarchy but am still a bit puzzled how exactly WordPress knows which file it should use for that Page.
Can anyone shed some light? | You need to look how page templates are saved against a page in the `wp_postmeta` table. Each page is linked to the specific template it uses and this is saved under the meta key `_wp_page_template`. You can go and have a look at your own install how you db structure looks like and how page templates are save
Wordpress does not use page slugs or page names but page id's to create the relationship to the page template assigned to it. Also, Wordpress does not use the template name to create the relationship to the page, but the page template file name. In the case of the default template, `page.php`, it is simply saved as `default` and not the file name
For that reason, you can rename the page slug and the template name to whatever you like and still have the relationship between the specific page and the template it uses.

How to check if a rewrite rule exists
A common problem with rewrite rules added in a theme is that there is no obvious hook on which you can flush the rewrite rules. The problem is getting harder when you update a theme with new code that includes new rewrite rules.
It seems like a good solution to the problem might be to detect if the rewrite rule exists and if it doesn't to flush the rules. So how can I check if a rule already exists? | If I understand correctly then you can hook into the rewrite api/process and flush or manipulate the rules that way? Read: **Plugin Hooks** on this page
Maybe something like:
// flush_rules() if our rules are not yet included
function my_flush_rules()
{
$rules = get_option( 'rewrite_rules' );
if ( ! isset( $rules['(project)/(\d*)$'] ) ) {
global $wp_rewrite; $wp_rewrite->flush_rules();

How to add new CSS file to new PHP file
I've made a new template file for Wordpress constructing the elements of the page via PHP and Wordpress recognizes the template as such.
Then I wanted to include a CSS file for said template (same folder) and went with the standard:
<link rel="stylesheet" type="text/css" href="style.css">
but for some reason the PHP file does not load the linked CSS settings. if I add
<? include('style.css') ?>
the content of it gets printed onto the page, meaning the php file can read it. So why doesn't it load the CSS settings?
Thanks for any help | CSS links are relative to the current request URI, not your PHP file. Use an absolute path like:

Visual Editor - Colorize Shortcodes
I want to highlight shortcodes in the WordPress visual editor in a specific color. E.g. I Have the following Shortcodes
[shortcode1] Some text [/shortcode1]
...
[shortcode2] Some text [/shortcode2]

What you need:

Shortcodes: override a shortcode / change shortcode on the fly
I've done a plugin where you can add shortcode like this: `[myplugin xx]` (where `xx` is a number which calls a specific content `xx`).
I have to do a multilingual version of my plugin, so here's my trick: my client writes content `xx` for language #1 and content `yy` for language #2.
Then, in an article, he would have to add something like:
[multilingualmyplugin #1 xx][multilingualmyplugin #2 yy]
and then I should just have to write a plugin that is called and change the content _before_ Wordpress calls my first plugin to either `[myplugin xx]` or `[myplugin yy]` depending on the domain name. Then Wordpress would call the plugin.
Is it possible and if so, where should I look? | Here's what I've done:created a shortcode where I do `[myplugin language="fr" id="5"][myplugin language="us" id="8"]` and then, when this page is called, it calls myplugin twice. If it's _not_ on the right page, my plugin returns nothing. So, when this page is called:
* if it's on a domain like "mydomain.fr" I just call `do_shortcode("othershortcode 5")`
* if it's on a domain like "mydomain.us" I just call `do_shortcode("othershortcode 8")`

Best location for theme translation files
I usually store language files in `/languages` folder that is located in theme folder and it's also recommended location by WordPress as well. However, it still doesn't look like the best solution because files will be overwritten after theme updates.
`load_theme_textdomain` function allows to specify a different location and I've been thinking to put languages folder inside of `/uploads` folder in order to prevent overwriting after theme updates. That folder will be created right after theme activation and language files will be copied there.
My question is, do you think this is a good solution or there is a better way that I'm missing?
I appreciate your insight about this matter. | ### Own theme
If you are using your own theme, no need to worry about, because `/languages` folder is in your control that way. :)
### Other's theme
But your concern is about other's theme and you want to apply your translations into that theme, then the best way is to make a **Child Theme**. Because you are actually _modifying_ that theme. Make your languages files and put them into your child theme's `/languages/` folder, and that's all.
If the parent theme is already translation-ready, it'll catch everything. But if it's not, then make a `functions.php` and show the translation-files' path:
load_theme_textdomain( 'theme-textdomain', get_stylesheet_directory() . '/languages' );
Note the `get_stylesheet_directory()` here, it's because we are showing the active theme's path. :) | stackexchange-wordpress | {

`
I want this because I am merging two WordPress websites and I don't want to loose the posts of the other website which are already published on Facebook etc with the old permalink structure. | You could use the Rewrite API. Since you have a fixed set of posts you could do the following:

'post-2' => 2

I've created a post_slugs array where the array keys are the old slugs and the array values are the post ids.
If you go this way, you have to go to Settings > Permalinks and hit the update-button, so the rules are active.

How to trace shortcode to its functionality

So I use the "Search in files"-function in Notepad++ (which I am using) and limit the search to the directory, where I think, I will find what I am looking for.

c:/xampp/htdocs/wordpress/wp-content/plugins/plugin-with-sortcode/

function NameOfFunction(

add_shortcode( 'nameOfshortcode'
add_shortcode('nameOfshortcode'
add_shortcode( "nameOfshortcode"

How to register a menu based on a ACF condition

Advanced Custom Fields: Conditional Statement with Select
I've set up a select field labeled "asset_type" with two values: "image" and "video". I then have two fields that rely on conditional logic to be displayed. If "image" is selected from the select I show the "image_asset" field, and if "video" is selected from the select I show the "video_asset" field. Reading through the docs and a few other stack questions, I thought I had the logic setup correctly, but for the life of me can not get the content to display. This is what my code looks like:
<?php if(get_sub_field('asset_type') == "image") { ?>
<div><?php the_sub_field('image_asset'); ?></div>
<?php } ?>
<?php if(get_sub_field('asset_type') == "video") { ?>
<div><?php the_sub_field('video_asset'); ?></div>
<?php } ?>
Any help or advice is greatly appreciated, thanks! | Just for the sake of closing the question:
<?php if(get_sub_field('asset_type') == "Image") { ?>

PHP inside echo HTML?
I am a little bit confused about the following code:
<?php
if (is_home() ) {
echo '<div id="bg" style="background:url("assets/img/header_1.jpg");">';
} else ( is_page( 52 )) {
echo '<div id="bg" style="background:url("assets/img/header_2.jpg");">';
}
?>
It is supposed to change the header background for different pages.
The code itself works, because CSS classes were imported correctly. Unfortunately "/assets/..." doesn't work so I suppose I need this function:
<?php echo get_template_directory(); ?>

How get posts from a subcategory of a category by name?
I'm trying to create a subcategory template of a defined category. For example, for each one, I would like to check if his subcategory `Photos` exists and to get posts of this.

— — — Subcategory ...
— — — Subcategory Videos
— — Subcategory Session 2013
— — — Subcategory Photos
— — — Subcategory ...
— — — Subcategory Videos
If subcategory `Photos` of **this** session category exists :
My idea is to have a query such as :
`$wp_query = new WP_query(... Session 20XX/Photos ...&showposts=20);`
Is there a way to do that please? | // Getting Parent ID

AND {$wpdb->posts}.post_status='publish'"

how to read database fields
Can someone please explain how to read the letters, numbers, and colons in the wordpress database?
For example:
a:1:{s:13:"administrator";b:1;}
in the wp-capabilities table.
Thanks! | Those are php serialized constructs. The one you have there is an array. If you are looking to read them as a human, it breaks down like this:
Array: a:size:{key definition;value definition;(repeated per element)}
String: s:size:value
There are other possibilities that you can read more about here.
Generally, you should never modify these directly since unless you do it perfectly you will break the record. To manipulate them with php you'd `unserialize()`, manipulate, and then re`serialize()`. e.g.
//get $my_serialized_variable from database
$value = unserialize($my_serialized_variable);
$value[] = $element_i_want_to_add;
$serial = serialize($value);
//write serial to database
If you absolutely have to modify it in the database, use a tool like this to make sure you have a valid serial. | stackexchange-wordpress | {

Can not manually create a database ( db, user, pass ) for a plugin
So I was working on a plugin and I needed to cache some third party API access, and I needed to manually create a database upon plugin activation or upgrade.

mysql_connect($db_host, $db_username, $db_password) or die(mysql_error());
mysql_select_db($db_name) or die(mysql_error());

Any thoughts ?
Regards,
Thank you lots! | As per GentlemanMax's comment, you'll want a table.
There's a really useful guide in the Codex (which also goes into how to do DB upgrades / migrations.)
One thing I'd emphasise: make sure to use `$wpdb->prefix` in the table name because not all sites will have tables beginning `wp_*`.
Also, if you're ever planning to distribute your plugins to other people, remember not every WordPress cloud hosting services will allow their customers to use custom tables (some of the larger ones allow the standard WordPress tables or preapproved plugins only – which is irritating but worth bearing in mind.) | stackexchange-wordpress | {

How to make a widget expand wider than the column width when editing its settings in the admin
The WordPress Text widget expands horizontally beyond the margin of the sidebar when added to a sidebar and opened in the admin and I am trying to apply that function to a widget. I see inline css is being dynamically injected when the widget tab is opened and inserts as
div style="z-index: 100; margin-left: -88px;" id="widget-50_text-4" class="widget open"
and though the widget, when opened, is wider than the sidebar, I am not seeing any width property. I figure it is being done with javascript and I have achieved the similar behavior using jQuery .css() but it is not screen size responsive as is the WP text widget, and I had to insert a width value.
Is there an add_filter function to execute this action?

How do you access the Product Short Description in a WooCommerce email template?

Can't understand $atts in functions?

$attr is not even used but still passed as an argument? Please explain. | In general, if arguments is not used or the defaults values are to used of an argument/parameter, you don't have to write it out, they can simply be omitted. The only time when you have to pass any value to an argument is when a function expect a valid value to be passed to it in order to properly execute, something like `get_terms()` which expects the first argument to have a valid taxonomy value
In your example, using shortcodes, it is not necessary to pass `$atts` as you are not expecting any values from attributes and you have not set up any attributes inside your shortcode function. Your shortcode simply returns a static value. In a case like this, you can simply just omit `$atts` | stackexchange-wordpress | {
