Advice: Template structure - php blocks in sidebar or someting else?
I'm trying to create certain modulair blocks which I can add to multiple pages in Wordpress. But I use sidebar-[name].php files for this, what is the best practice for this? Should you add them to a function or add them in a sidebar...
It feels Kinda off using many sidebar's. It would be nice if I could add them to a sub-folder in the template. Checkout the image. How do you do this?
!enter image description here | I would say to add them as template parts as in content-[name].php. For instance in `page.php` you could have something like:
<?php while ( have_posts() ) : the_post(); ?>
<?php if (is_page( 'home' ) ){
get_template_part( 'content', 'benefits' );
} elseif (is_page( 'Contact' ) ){
get_template_part( 'content', 'contact' );
}
}
get_template_part( 'content', 'popup' ); ?>
<?php endwhile; // end of the loop. ?>
It seems to make more sense as it is content after all. | stackexchange-wordpress | {

WP Query / Meta Query
How can I use a meta query like this:
>>>>>> KEY_X Conditional IS ABSOLUTELY REQUIRED <<<<<<<<<<
array(
'key' => 'Key_X',
'value' => 'Value_for_X'
),
>>>>>> KEY_Y **OR** KEY_Z ARE REQUIRED / AT LEAST ONE <<<<<<<<<<
array(
'key' => 'Key_Y',
'value' => 'Value_for_X'
),
array(
'key' => 'Key_Z',
'value' => 'Value_for_Z'
)
So the first one is an absolute must, and then one or the other is required (at least one).
Thank you so much!
Ciprian | Short answer: You can't do that.
The query system is a simplified version, by design. It cannot do combinations of ANDs and ORs across keys like that.
If you want to do that, you'll need to write your own SQL in some manner. The meta_query is not capable of that complex of a query. | stackexchange-wordpress | {

Strip Image Classes from HTML Output
Does anyone know how to remove all of this from the image HTML?
class="aligncenter size-full wp-image-31053" | Take a closer look at get_image_tag() which can take a lot of parameters like `$id`, `$alt`, `$title`, `$align`, `$size`.
If you look even closer you'll find the `get_image_tag_class` filter to change the image class names (like class, ID, align and size).
You can use the filter within your `functions.php` like this:
Note: This will still return an empty tag like: `class=""`
function strip_image_class($class, $id, $align, $size) {
return '';
}
add_filter('get_image_tag_class', 'strip_image_class', 0, 4);
Update: To completely remove everything related to the class you'll have to filter the `$html`:
function strip_entire_image_class($html) {
return preg_replace('/ class="(.*)"/', '', $html);
}
add_filter('get_image_tag', 'strip_entire_image_class', 0, 4); | stackexchange-wordpress | {

esc_url returns incorrect URL
What would be the reason for `<?php echo esc_url( home_url( '/' ) ); ?>` to be sending me to an incorrect website?
I use it in my search bar and when I search a value it sends me to one of my other websites, but I am not sure what I did to make this happen. | It ended up being something very easy, but something I overlooked. Since I always use `<?php get_search_form(); ?>` for my search forms, I naturally assume that in my section template for the search area, I was using that, but I was not.
I built the theme custom off of another theme I built for a different website and for some reason in the form's `action=""` I hardcode the url for the first site; that is why I kept getting forwarded there.
I thought I checked the section, but must have overlooked it. After two days or so, I decided to re-check the section, thanks to the suggestions in the comments which made me re-think the problem.

Wordpress Translate Explaination
I'm dissecting Wordpress's default theme TwentyThirteen in attempts to learn more about wordpress.
I ran into a function call that I simply don't understand even after reading the short codex description.
I would greatly appreciate insight on why the programmers/developers decided to format the edit link in this way.
edit_post_link( __( 'Edit', 'twentythirteen' ), '<span class="edit-link">', '</span>' ); | We have two main functions for translations, `_e()` and `__()`. The first _prints_ the value, and the second _assigns_ the value.
As we are feeding a value to a function, we don't print or `echo` (the `e` in the function) anything, so we use the assignment function `__()`.
What happens is that `edit_post_link` will receive the translated string for `'Edit'`.
As for the function, `edit_post_link($link, $before, $after)`, we could do something like:
edit_post_link( 'Edit this', '<strong>', '</strong>' );
And it would make the edit link with a custom, untranslatable, string in bold. To learn more you can dig in the archives of this site. | stackexchange-wordpress | {

Updating a live theme safely?
Apologies for the general question, but I spent some time looking for an answer and couldn't find anything.
I often find myself in a situation where I need to make tweaks to a live site based on a client's feedback after going live, so I'm wondering the best way to quickly make changes on the live site without disruption.
Presumably it's possible to duplicate the live theme, rename it in style.css so that it's considered a 'new' theme yet still uses the same database etc. and then work on that? The question is, how would I view that new theme and then switch to it once all updates are done?
One day, I'll need to get my head around GIT as from what I've heard that would solve this kind of problem in a very safe way. | As far as my understanding you want to make changes in the theme without affecting the main theme so For this purpose the best practice would be creating child theme. So you can edit this child theme and your main theme will be safe. So, you can update the theme safely.
Refer to WordpressCodex on creating child theme.

wp query by search in titles only & put the posts in loop

redirect attachment page to category page
I'd like to prevent google from indexing my attachment/image pages. So for the images I placed in my posts that's no problem - I just redirect the attachment page to the post parent by creating a new file "image.php" with this code `<?php wp_redirect(get_permalink($post->post_parent)); ?>`
The problem is though that I got images in my category descriptions, which don't even have a post parent, so the redirect doesn't work.
Is there a way that I can redirect the attachment page to the category page that has the picture in its description? Or maybe a way I can put all my attachmentpages on noindex? | The best way for this is either use:
Attachment Pages Redirect plugin or use Wordpress Seo.
You can use Attachment pages redirect to redirect the attachment pages to post page or home page. And also you can use WordPress SEO to redirect to homepage.

Use Filename for Alt and Title Tags
I currently name all of my image files like this:
Earth the Blue Planet.jpg
Which when uploaded gets changed to this:
Earth-the-Blue-Planet.jpg
I was wondering if it is possible to have the image's alt and title tags render like this using the filename when adding them to posts:
alt="Earth the Blue Planet" title="Earth the Blue Planet"
I know the title tag shouldn't be used like that, but I'll just be using the filename as a base to add in the information I want. This would just make it easier.
Thank you so much! I love this place for all my Wordpress questions! | The `alt` tag already takes the filename but if for some reason you need to replace hyphens with spaces and include a duplicate title of the alt tag you can do something like:
function wpse_120228_seomadness($html, $id, $caption, $title, $align, $url, $size, $alt) {
$alttitle = str_replace('-', ' ', $alt);
$img = get_image_tag($id, $alttitle, $alttitle, $align, $size);
$html = '<a href="' . esc_attr($url) . '">' . $img . '</a>';
return $html;
}
add_filter( 'image_send_to_editor', 'wpse_120228_seomadness', 10, 9 );

Is it acceptable for a WordPress theme to not accept widgets?
I'm developing my own WordPress theme, and I was going through the Theme Unit Test as described by the Wordpress Codex. Now, at some point, the Codex mentions that I should verify that
> All widgets display correctly
Now, on the other hand, I have seen in the Widget help page that is instructed for users to verify if their theme supports widgets at all.
So, **is it ok if my theme does not support widgets?**
My goal is to have it published at some point and available to users through the Wordpress.org site, but since the design is quite minimal, I had decided not to support widgets. Am I asking too much? | It depends on where you distribute the theme. If you want to place it on WordPress.org, it must allow and display widgets. If you release it via your own website, or some others possibly, widgets can be optional, though I would always recommend they be supported. | stackexchange-wordpress | {

Cannot update user display_name field
I'm trying to update user display name when posted through a form.
Here's what I'm trying:
if ( !empty( $_POST['display_name'] ) ){
//var_dump($_POST['display_name'] );
wp_update_user( array ( 'ID' => $current_user->ID, 'display_name' => esc_attr( $_POST['display_name'] ) ) );
}
I can see that the display name is posted correctly, but it just does not update it. I can update the user url successfully but not the **display_name** and **first_name** / **last_name**. Is there any other way to update these fields? | This is because there is no **meta key** named **display_name** , so if you want to update a single meta value better use `update_user_meta` instead of `wp_update_user`, as **update_user_meta()** will create the meta field if it doesn't exist.
like
if ( !empty( $_POST['display_name'] ) ) {
update_user_meta( $current_user->ID, 'display_name', esc_attr( $_POST['display_name'] ) );
}
Then you can use the meta key and value the way you want. | stackexchange-wordpress | {

Completely disable categories
Is anyone aware of a plugin that disables categories in WP?
By this, I mean completely hiding the feature from view automatically, for existing and new users alike. In particular:
* the WP admin menu
* the posts list, its screen options, and its filters
* the post editor and its screen options
* the widgets screen
* the writing and permalink settings screens
I've run into a variety of aging hacks to do part of this, namely and mostly code to disable meta boxes and a handful of plugin to disable the permalink prefix. I'm turning to SO in the hopes that some web designer or developer might have the entire set of features on hand.
If not, might there be new APIs from the past 3-4 years that make the process simpler (my WP skills are getting rusty), or is seeing it through going to be an awkward output buffer manipulation-related hack? | With most credit due to this stackexchange answer:
function wpse120418_unregister_categories() {
register_taxonomy( 'category', array() );
}
add_action( 'init', 'wpse120418_unregister_categories' );
This technically leaves everything in place (so you could bring it back at any time without a loss of data), but it "unhooks" it from everywhere in the admin by removing it from all `$object_type`s.

save_post action firing before I publish / save the post
I'm trying to update a posts meta only after it has been saved or updated.
My function is pretty simple

update_post_meta($post_id, 'copied', '1');
update_post_meta($post_id, 'blurb', 'this value updated by save_post action');
}
add_action( 'save_post', 'update_test');
When I add a new post at `wp-admin/post-new.php` I can see the two custom fields values have already been updated. The fields themselves exist with Advanced Custom Fields. But shouldn't be updated until after the post has been published / saved and or updated. Why is this updating the fields as soon as the post-new.php form loads? | A draft or "blank" is saved as soon as you start to create a new post. Those new posts have the `post_status` of `auto-draft`. Check for that to prevent your callback from firing on those "blank" post saves.
function update_test( $post_id, $post ) {
if (isset($post->post_status) && 'auto-draft' == $post->post_status) {
return;
}

Is there any plugin hook that I can latch onto once a site is freshly installed?
To customize a fresh new WP install, there are a bunch of pluginable functions that can be overridden. Namely `wp_install()` and `wp_install_defaults()`. And `wp_new_blog_notification()`.

I'm not finding any obvious hook to do so in the `wp-includes/upgrade.php` file, however. Might I be missing anything?

get_post_gallery_images returns thumbs . I want full size
I have the following code on my site.
<?php // image gallery content
if( has_shortcode( $post->post_content, 'gallery' ) ) {
$gallery = get_post_gallery_images( $post->ID );
$image_list = '<ul id="cfImageGallery">';

WooCommerce custom payment gateway
I'm trying to write a WooCommerce plugin for a client's website that they're going to be selling subscriptions to customers. I've been exploring my options and the best one I can come up with is to roll my own payment gateway module to handle this. (Other advice appreciated if anyone's ever tackled something like this).
However, I'm trying to add a custom payment gateway, but it doesn't seem to be working up. It's not showing up under `WooCommerce -> Settings -> Payment Gateways`. The plugin is installed and activated in WordPress, and I've followed a couple guides from their docs pages.
* WooCommerce version: 2.0.18 (via plugin installer)
* gist code
I really don't know why or what would cause my payment gateway isn't showing up.
Thanks for the future help. | Right, so the gist is your code; from your description I thought it was someone else's code you read for inspiration.
Your woostripe.php file, which loads your gateway class, bails out before loading the gateway class:
// bail on constructor if gateway class isn't loaded!
if (!class_exists('WooStripe_Gateway')) return;
// ...
// why are you attempting to load WooCommerce's classes? Don't!
include_once(dirname(plugin_basename('woocommerce.php')) . 'classese/abstracts/abstract-wc-payment-gateway.php');
// never gets here to load this class, you've already left this function...
include_once(dirname(plugin_basename(__FILE__)) . 'classes/WooStripe_Gateway.php');
Remove the include statement for WooCommerce's class, that's WooCommerce's job not yours. Then move your WooStripe_Gateway include to the top of `woocommerce_gateway_init()` **before** the test to see if it exists. That class cannot exist until it is loaded. | stackexchange-wordpress | {

WordPress filtering utm_ GET variables from url unless logged in as admin, not sure why?
So I am having an issue where I can't pull variables such as mysite.com/?utm_campaign=testing unless I am logged in as admin or editor.
When logged out and just a regular users I can't grab any variables which start in utm_ such as utm_campaign. However utmcampaign works, and any other variable I try. Just not utm_ ones.
I disabled all my plugins but still have the same issue. Not sure where the filtering is coming from and not sure why it only filters when not logged in as admin.
I tried accessing the variable using three different methods: 1\. Injecting PHP code using the "Code Insert Manager" plugin
<?php echo $_GET['utm_testing']; ?>
1. Using the built-in function of formidablepro to grab the GET variables.
2. Using the same code as #1 but inside my footer.php file of my template.
All have same results. | It's not a core behaviour to overwrite the global $_GET array, which means it's likely that something else then WordPress itself is the issue here.
I would suggest the following steps to debug the issue:
* Disable all active plugins and revert to standard theme, see if the problem persists.
* If the problem is still there, open the `index.php` in your document root and write `var_dump($_GET); exit();` in the first line to see if the variable is making it through the webserver. If it isn't showing up now, it means that it is filtered for some reason by the webserver (i.e. bad .htaccess rule, or conflicting mod_security rule). | stackexchange-wordpress | {

Empty folder being created by Wordpress, breaks site
I have a page on my site at mysite.com/publish. This page leads to a members area where they can add/edit posts from the front end.

How to show more than 10 order on woo commerce order view

is there any way to put pagination to show all of order history?
I also wonder which file, function I need to modify if I want to add "see more" button at the bottom of the order page show 10 each when it's clicked. we may work on "see more" button with ajax.
Thanks, | It appears the shortcode uses the key `order_count` and not `per_page`. You can modify this on the View Order page, where the shortcode exists.
[woocommerce_view_order order_count="20"]
~~If you would want some kind of AJAX order loader you may have to make some significant changes.~~
A note `order_count` also accepts the parameter `all` which will get all orders. Perhaps that is a solution?
**EDIT:**
The shortcode uses the template file `myaccount/my-orders.php`. You could modify this to look through a certain amount of orders, seperate them into seperate divs and have it show the additional divs with each button press.
It is also in this template file where they actually get all the orders, so you could add a `paged` parameter to this and quite easily do the AJAX content load. | stackexchange-wordpress | {

A loop like yours assumes the data from the "main query". You've created a custom page template so the main query on that page is going to be the single "TestPage" data. That is the way it is supposed to work. That is, `if ( have_posts() ) : while ( have_posts() ) : the_post();` doesn't always give you the post archive data.
To get the posts you'd need to create a new query and loop over that. Like this:
$newq = new WP_Query(array('post_type'=>'post'));
if ($newq->have_posts()) {
while ($newq->have_posts()) {
$newq->the_post();
the_title();
}
}

dynamically update permalink and title with the values of custom fileds
Im working on an interface for a custom post type where I need the post title to carry the date and venue name. So on the Admin end I've got js that dynamically populate the title as the user fills out the form. If the user dosen't languish this information is then saved as a part of the permalink. Sometimes however the post is saved as a draft before the title is populated and we end up with an misleading URL.
My feeling is that it would be best I were to just hide the title all together on this post type, and look for a hook to populate the title AND rework the post url with the field values the user has set when saving the post. As of now I cant find any hooks or filters that look like they would be of help. !example screen shot
Help? | You don't need to hide the title. To my knowledge there is atleast two way to do this, one is manual and other through codes.
Manual way:--
After you are done with adding the title, if your permalink doesn't match the title just click on **permalink Edit** button clear the text and click **OK**. It will get you the permalink as per the title.
Through Code:--
Put the below code in the theme's functions.php file.
add_filter( 'wp_insert_post_data', 'wpse_121035', 50, 2 );
function wpse_121035( $data, $postarr ) {
//Check for the post statuses you want to avoid
if ( !in_array( $data['post_status'], array( 'draft', 'pending', 'auto-draft' ) ) ) {
$data['post_name'] = sanitize_title( $data['post_title'] );
}
return $data;
}
The above will automatically change the permalink of the post on the fly.

Get value in custom field with taxonomy
I have custom field `my_cf` for Taxonomy/Term. How can I get and output value with custom field for taxonomy/term?
I've tried using:
$variable = get_field('my_cf', 'basic');
echo $variable;
where basic - name for my taxonomy. But this doesn't work.
Any suggestions? | I can't really explain it any better than the ACF documentation page I posted in the comments:
> All the API functions can be used with a taxonomy term, however, a second parameter is required to target the term ID. This is similar to passing through a post_id to target a specific post object.
>
> The $post_id needed is a string containing the **taxonomy name + the term ID** in this format: **$TaxonomyName_$TermID**
So if your custom field is `my_cf`, and your taxonomy name is `basic` ( _not_ term name) and the term ID within your taxonomy is 42, then you need:
$variable = get_field( 'my_cf', 'basic_42' ); | stackexchange-wordpress | {

Storing values in Post Meta vs new tables
I want to store list of user IDs in the post meta who have rated a post . So, for each post I will need to check the post meta to see if the user id exists in it or not.
So my question is that, is it good idea to store that information in the post meta OR should I create a table and add it in the table. Will there be any difference in the performance (table vs meta) if the number of values grow very much?
I would prefer to store in the post meta as it is much simpler and cleaner way, but I have read one answer which says
> never, ever, ever, use an EAV (aka the post_meta table) to store data that you might to need to query. | Based on your comment:
> when a user clicks to vote, i get the value of that post meta and check if the user id exists in that (using php explode and foreach). If it does not exist then i add the user id in it.
there's no query involved there, so it's perfectly fine to use post meta for that purpose.
A query would be something like "load all posts from database where user with ID n has voted". That would be more difficult to achieve, as it's a many-to-many relationship, which WordPress doesn't do natively. Storing user IDs as serialized data (an array) is a PHP construct, MySQL doesn't "understand" that data natively, so that would not be a good use of post meta. | stackexchange-wordpress | {

Using post ID in custom tinyMCE button

Just for this example, code from this tutorial: < can be used, and after clicking on the button, current post id could be logged into console (console.log) or alerted to screen. | You would need to place a globally namespaced javascript variable in your php code where you enqueue the script to be loaded for the editor pages.

var post_id = '<?php global $post; echo $post->ID; ?>';

Change appearance based on category but post is in two main categories
I want to change header and menu based on what category a post is listed in.
I could duplicate the post and assigned each of the two categories separately but this sounds messy and bleh.
The post/s in this example belong in both "pirtek" and "btcc".
<
but the posts with pirtek need to be styled with custom header etc. (and eventually custom menu...which makes me think perhaps I should just duplicate for easy implementation of a seperate menu?)
What do you think? As it stands my standard header is prioritised every time
<php
if ( has_category('pirtek') ) {
$header = '
} else {
$header = '
}
?> | One easy way is to use `has_category` function.
E.g. in your header you can use
if ( has_category('pirtek') ) {
$header = '/path/to/pirtek/header'
} else {
$header = '/path/to/standard/header'
}
If the post has the 'kirtek' category, then the condition inside `if` is `true`, no matter what other categories the post belongs to.
This kind of `if` statement can be used everywhere you need, however, the snippet above works well in singular templates and inside the loop. If you want to use that conditional outside the loop, you need to pass the post object as second argument of `has_category`.
$postid = 10;
if ( has_category( get_post($postid) ) ) {

// can you declare a bogus session variable, yours might just be empty

Custom fields in Permalinks?
I'm wondering how to add a custom field value to a custom post type's permalink? For example, I have the custom post file ex: cpt-cities.php, which handles registering the custom post type and all of those specifics.

However I'm not able to get the value of the custom field, and get_post_meta() does not work. This may be due to $post->ID not working (since it's within the custom post type file, and not a post loop).

Any help is greatly appreciated, this is one of the last parts of a pretty extensive project. | 1. Use `add_rewrite_tag( $tag, $regex );` to register a rewrite tag for the custom field.

Function naming convention

Edit: Re-worded the question **Q: Are there any patterns that help developers co-working on the projects namespace functions to avoid confusion whether they are native to Wordpress or not?** | I almost used the same convention as @GhostToas but to me I usually use classes to minimize conflict.

How to handle a Wordpress blog with articles in different languages?
Most multilanguage plugins have the approach to provide each post in different languages. In that case, qTranslate or WPML are good plugins. But in my case, articles have one language and instead of translating them, there should be versions of the blog showing only the content in one language.
For example the `en.example.com` should only show posts written in English language, and also display Theme texts in English, while `de.example.com` should only show German articles and also use German as system language for Wordpress.

</ul></div>
I want to be able to intercept this somehow and insert my own HTML programmatically before the closing `</ul>`. How do I hook it up? | Before being printed, all the menu items get run through a filter. You can target the `wp_nav_menu_items` filter to tack things on to the menu:
// Filter wp_nav_menu() to add additional links and other output
function new_nav_menu_items($items) {
$homelink = '<li class="home"><a href="' . home_url( '/' ) . '">' . __('Home') . '</a></li>';
// add the home link to the end of the menu
$items = $items . $homelink;
return $items;
}
add_filter( 'wp_nav_menu_items', 'new_nav_menu_items' );
Or, to be more specific, you can target only the desired menu by replacing the `add_filter` line from above with the following, and replacing `$menu->slug` with your menu's actual slug name:
add_filter( 'wp_nav_menu_{$menu->slug}_items', 'new_nav_menu_items' );

Let users register weight each day and save it in DB
I need a way that lets my users register they're weight (kg) and maybe % of bodyfat and save that information on each user in the DB.
Then i need a way to output that number again on the logged in user
What would be the easiest approach to do something like this? | I feel the best way to do is add two options `Body weight` and `Body fat(%)` in the user profile, and then you can show it with the user logged from the db. I guess this would be a simpler way. | stackexchange-wordpress | {

Author profile comments system
I have a custom PHP file to get all the users/authors from the DB in WP, so it's all showing correctly and working BUT, I want to make the comment to work properly, what i did now is:
<?php comments_template(); ?>
I added the above line in the file, but the issue is that if i comment on one author the comment won't stay ONLY on his profile page, but it will publish in all the authors page, it's like the comment are not individual....
Any ideas how can i make the commenting work for each author separated from the other? | Comments are bound to post IDs. So you need a post ID for each user.
Register a custom post type, make it not public and create one hidden post for each user. Store the ID in an user-meta field.
Now assign the comments to that post’s ID. Do not use `comments_template()`. That’s an ugly monster, dealing with globals and way too complex to hack around. Fetch the comments with `get_comments()` instead.
The print the comment form, add a hidden field for author archive URL, hook into `comment_post_redirect` and send the commenter back correctly. | stackexchange-wordpress | {

How can I filter a query by post id?
In my wp_postmeta table, I have the following values:
!enter image description here
I'm trying query the posts whose ID lie in the `meta_value` column associated to a given post (the current post being viewed).
For example, lets suppose I'm viewing post `94`. As illustrated above I would like to retrieve the posts `108,78,90` associated with `94` and display their titles.
In this way the an area (post type) is associated with a post by its ID being one of the meta values for the post's 'area' meta key.
I start with this:
$args = array(
'post_type' => 'area',
'posts_per_page' => -1,
);
$areas = new WP_Query($args);
But how I can specify I want the posts associated with the post `94`? | So you want the values `108,78,90` corresponding to the meta key 'areas' for the post with ID 94?
First retrieve those IDs:
$the_post_id = 94;
$area_ids = get_post_meta( $the_post_id, 'areas', false );
//Make sure they're all positive integers
$area_ids = array_map( 'absint', $area_ids );
if( $area_ids ){
//We have IDs, retrieve posts
$areas = get_posts( array(
'post_type' => 'area',
'numberposts' => -1,
'post__in' => $area_ids;
));
if( $areas ){
//We have areas
foreach( $areas as $area ){
echo get_the_title( $area ). '<br/>';
}
}
}
The above has not been tested, but should work in theory. If you want `$the_post_id` to the be ID of the post currently being viewed then you can use `get_the_ID()`. | stackexchange-wordpress | {

How is comment spam received without a comments form?
The theme one of my sites is using does not have a comments form nor is there any HTML markup for comments anywhere within the code.
So, how am I receiving spam comments?
All the spam is caught by akismet and I can change the Discussion Settings so only registered and logged-in users can comment (and a few other settings) -- so the question is not "HOW to reduce spam" but how do spammers (bots or humans) submit spam without a form? | You don't need a form to submit a comment to the wp-comments-post.php file, or to send a pingback or trackback. Spammers don't use forms, they simply send their spam directly.
Removing the form doesn't "turn off" comments. To do that, go to the Posts screen, and use the Quick Edit to actually disable comments and trackbacks for the various posts. Also visit the Settings->Discussion page, and set it to disable comments and trackbacks for new posts as well.
Once you do this, then the comments being sent directly will be rejected by WordPress. That will actually turn them off. | stackexchange-wordpress | {

How to keep WP from using https to get to wordpress.org?

This has nothing to do with your server supporting SSL as a server. In this case, WordPress is acting like a web-browser, and trying to make an HTTPS connection to WordPress.org, so that you can download files securely.
Typically, you need to reconfigure your PHP installation on the server so as to have CURL and OpenSSL available to PHP. How to do this precisely depends on your hosting service or system. | stackexchange-wordpress | {

Where to populate custom terms in custom taxonomy in plugin?
I have a plugin that successfully creates a custom taxonomy for a custom post type.
What I'd like to do, is on activation (or wherever works), create a default set of terms for the custom taxonomy. I've successfully done this before by using `wp_insert_category` in a function called upon plugin activation.
That same function isn't working for the custom taxonomy, though. My guess is that it is because the custom taxonomy isn't registered yet when the function gets fired.
I can't seem to find out where to hook the function so that it works with a custom taxonomy. I've tried calling the function from `wp_loaded` also and I curiously get `Call to undefined function wp_insert_category()` That puzzles be as well because I thought that hook meant all of Wordpress was loaded.
Any advice would be greatly appreciated.
Thanks. | Hook into `registered_taxonomy`. This is called after the taxonomy was registered successfully.
Sample code:
add_action( 'registered_taxonomy', 'insert_default_terms', 10, 3 );
function insert_default_terms( $taxonomy, $object_type, $args )
{
if ( 'your_tax_name' !== $taxonomy )

Wordpress hide the username/password fields in login page

label[for='user_name']
{
visibility:hidden !important;
}
label[for='user_pass']
{
visibility:hidden !important;
}

function wpse_121687_hide_login() {

$style .= '.login form{ display: none }';
$style .= '.login #nav a, .login #backtoblog a { display: none }';
$style .= '</style>';

How long is "as long as possible" in wp_cache_set()?

Changing the site URL
# Overview:
I have a self-hosted WordPress installation _currently_ without a domain.
Example: <
In a few days a domain will be pointing to this installation and I'll need to update the site URL. I'm not migrating. I'm simply changing the home/site URL from an IP-based URL to a domain-based URL.
I've already read through the codex on the matter but apart from changing the Home URL and Site URL under General Settings, the codex appears to be outlining fixes rather than any other steps additional to changing the URLs via General Settings.
# Questions:
1. In your experience, is it a straight forward process changing from an IP-based site URL to domain-based site URL? Is it a problematic affair that should be avoided by creating a fresh hosting account entirely?
2. Is anyone aware of potential problems this could create with plugins such as WooCommerce?
Note: I have reviewed existing questions/answers on this website. | If you have access to phpmyadmin the best way in my opinion is to get WP migrate Db Plugin, then create an export sql file with new url address and upload it with PhpmyAdmin.
That way you ensure that every place in the site with old url get replaced with new url in a **safe way** (you can't do a simple search and replace because it won't work)
Regarding your 2 questions: 1 With this plugin is pretty straight forward. Create a database backup just in case, but you shouldn't have problems 2 No problem if is replaced this way. | stackexchange-wordpress | {
