Bulk delete WordPress posts with phpMyAdmin
I have over 8,000 posts generated by wp-o-matic and I want to get rid of all of them.
I want to execute this query in phpMyAdmin. I just want to make sure this is safe to run and it's not wiping out my pages. This is the query:
DELETE FROM 'wp_posts' WHERE 'post_type' = 'post'
Thanks | The join isn't that complex, but I wouldn't bother with it. Since you have a lot to remove a direct SQL query will run a LOT faster than WP.
However, we do need to keep track of the post ID numbers and remove the descendants and metadata.
Not tested / Make a backup / your risk etc. etc.
create temporary table `cull` (`post` int);
insert into cull select ID from wp_posts where my_criteria = 'my value';
delete from wp_posts where ID in ( select post from cull );
delete from wp_posts where post_parent in ( select post from cull );
-- done with temp table, cleanup metadata
delete from wp_postmeta where post_id not in ( select ID from wp_posts );
delete from wp_comments where comment_post_id not in ( select ID from wp_posts );
delete from wp_commentmeta where comment_id not in ( select comment_ID from wp_comments );
delete from wp_term_relationships where object_id not in ( select ID from wp_posts ); | stackexchange-wordpress | {

How to display a term of taxonomy
My doubt is how can I show a "term” of an specific taxonomy, the problem is that I have not found an applying example, just short code lines that don’t show me nothing at all.
I want please the entire code to show the post.
My post type names: “sección_deportes"
My taxonomy names: “tipo_deporte”
and the term I want to show: “futbol”
I just found this: <
but the loop shows me the same posts repeatedly. | I found the solution thanks to answer this question: Specify number of posts in my 'tax_query'
I wanted to show the posts for 'futbol' within the 'tipo_deporte' taxonomy:

'posts_per_page' => 2,
'tax_query' => array(
array(
'taxonomy' => 'tipo_deporte',
'field' => 'slug',
'terms' => array('futbol'),
)
)
);
$query = new WP_Query( $args );
if ( $query->have_posts() ) {
while( $query->have_posts() ) {
$query->the_post();

Include both default and Custom Post Type in query modified inside pre_get_posts

What changes will I have to make? | As Kaiser mentioned, the `post_type` parameter can accept an array of post types. Updating the function to use `is_main_query()` to limit the filter to only the "main" query, the code would look like:

wpdb update add current timestamp not working

WordPress has a number of date/time related functions. In this case, it sounds like what you need is `current_time()`, which...

remove all submenus from plugin

Pagination options using xml data instead of database?
Working on a custom plugin. I have an XML file containing over 500 items I need to make available for posting at the client's discretion. The client wants to share this plugin among a small group of peers, with no access to a central database, hence the XML file. We've done something similar in the past using data stored in a MySQL table and WP_List_Table for display and pagination, but I'm unsure about how to proceed using XML.
I'd prefer we create all posts as drafts that they can publish as desired, but for reasons I don't quite comprehend, that's not an option.
Basically, they want to see a list of all available items where they can simply click to publish individually or check multiple items and publish in bulk. Does that make sense? | No central database? Talk about not being able to see the forest for the trees. As long as the XML document is included with the plugin, I can just create a custom table and proceed as we have in the past. I do understand WP_List_Table is marked private, but I don't see anything wrong using it for a private plugin that will never make it to the repo. | stackexchange-wordpress | {

'Trying to get property of non-object' when using WP_Query with 'fields' => 'ids'
In an attempt to speed up my query, I'm using the following arguments:
$args = array(
'post_type' => 'product',
'fields' => 'ids',
);
$query = new WP_Query($args);
While this does return an array of IDs as expected, I keep getting multiple `Trying to get property of non-object in /wp-includes/query.php` notices. This happens even when I have nothing inside my `while` other than `the_post()`:
if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post();
endwhile;
endif;
Is `the_post()` causing this? Any idea why I'm getting these notices? | `the_post` places the next post object from `$query->posts` in the global `$post` and calls `setup_postdata`, which assumes `$post` is a post object, as it tries to access member vars of that object, which is where the errors come from.
In this case `$posts` is just an array of IDs instead of post objects. If you want to iterate over the results, you can do a `foreach` on `$posts`:
$args = array(
'post_type' => 'product',
'fields' => 'ids',
);
$query = new WP_Query($args);

post_content with line breaks
I want to be able to get post_content with line breaks. What is the best way to do it?
I previously use the_content() which was working fine until I needed to install a plugin that adds share buttons on each post.
Since then the output of my the_content includes texts from the share buttons.

$getPost = get_the_content();
$postwithbreaks = wpautop( $getPost, true/false );
echo $postwithbreaks;

Show Sitename on Yoast SEO Title tag
I am using Yoast SEO plugin on a site. Right now if a Post's Title is left empty in the metabox for a post, then the Title tag will output in this format...

Custom Login iframe doesn't work

WP Plugin Running before jQuery
I'm having problems with jQuery and a plugin, the console error says jQuery is not defined. What I don't understand is it only fails when I load it to the production server, on my local dev installation it worked perfectly.
> ReferenceError: jQuery is not defined.

function enqueue_styles() {
wp_register_style('sjcss', plugins_url('/css/sjs.css', __FILE__), false, '2.1');
wp_enqueue_style('sjcss');
} | Your code doesn't work because of a fundamental ordering problem.
You're hooking into wp_footer. Then you're registering a script and enqueueing it. Finally, you echo some code.
Here's the problem, the act of enqueueing a script does not cause an echo of the script code immediately. Enqueueing does just what it says, it sets the script up to be added to the page output at a later time. So your echo of the script code here is too early.
Specifically, the enqueued scripts for the footer happen in the wp_print_footer_scripts call, which is connected to the wp_footer action with priority 20. So you need to enqueue before then, but print your custom script code after then.
So make a new function. Hook it to the wp_print_footer_scripts action. Then move your echo code into that, but leave the enqueue code where it is. | stackexchange-wordpress | {

Wordpress Background Audio - Continous AutoPlay
I'm kinda of a newbie , but know my way around a bit in Wordpress to code things in place.
I would like to know if you happen to know how to create a continous audio play in the background of the website , _including_ the time a visitor clicks on different pages, posts or sections of the website.
I have tried coding the audio into but that doesn't solve the problem because when the page reloads, the audio starts over and I don't want that.
Coding , plugins ... whatever does the job.
I know that this is not quite ok for the visitor , but please bear with me.
Thank you. | Since I don't have enough reputation to add a comment yet, I read on another website that someone used < as an alternative to frames/popups which seems to be a little script you can generate and then use on both non-WordPress and WordPress sites (since it just needs to be inserted after the `<body>` tag).
Or you can self-host the script (source) but either way, you should be aware that there are reported issues with SCM Player at the moment.
So without commenting on whether this script is a good or bad approach, how you apply it to your WordPress install will differ depending on your theme and if you prefer to self-host etc. But it will involve editing of theme files; whether this is your child theme or adding the relevant scripts to your theme's functions.php | stackexchange-wordpress | {

How to display Feedburner subscription count as plain text via a shortcode in post/page editor of my Wordpress blog?

How to display post title and link within wp_list_categories()
I'm testing something which needs to display posts within `wp_list_categories()`. Basically I want to display all content for a taxonomy.
I'm pretty sure that to make it happen I have to alter the WP class or function that handles categories and stuffs like this. Is that the way?
**EDIT:** I've opened the core file that contains `wp_list_categories()`. It's in `wp_includes` in the file called `category-template.php`
How can I alter this?
**EDIT 2:** there's a filter `wp_list_categories` | Off the top of my head, you can achieve the desired effect in two different ways.
## Extend the Category Walker
Extend the `Walker_Category()` class and overwrite the `start_el()` method with similar code that retrieves a list of posts in the category being processed and displays them in an unordered list within the category's `<li>` element. To use your new walker class, pass it's name in the `walker` argument of `wp_list_categories()`.
## Procedurally Process Cateogries
Rather than having `wp_list_categories()` echo out a list of categories, set the `echo` argument to `false`, set a variable to the function call's return value, and use the PHP regular expression and string functions to modify the markup as needed.
The second solution can alternately be achieved by hooking into the `wp_list_categories` filter, which receives the same generated markup as an argument that `wp_list_categories()` returns when `echo` is set to `false`. | stackexchange-wordpress | {

["ID"]=> int(2322)
["post_author"]=> string(1) "0"

Why does get_posts() returns posts of authors whose ID is **not** 11? | `post_author` is not a valid parameter for `get_posts`. You really need to look at `WP_Query`'s argument list to see that, as `get_posts()` is really just a wrapper around that class.

I would strongly consider passing a parameter with the request though. You should already have the post ID and possibly the post data on the referring page and won't have to make separate queries to grab it.
You can use a `nonce` to help prevent abuse of the parameter-- that is, to prevent someone from just typing `?status=free` into the URL.

single_term_title() running before get_the_title()
This is a strange "problem" but I've had this happen on a few installs and I was wondering if anybody could give an explanation on why / how this happens.
On a blog category if I code:
`<?php echo get_the_title(1).': '.single_term_title(); ?>`
Outputted to my screen: `UncategorizedBlog:`
On the otherhand, if I do this:
`<?php echo get_the_title(1); ?>: <?php single_term_title(); ?>`
I get the correct output `Blog: Uncategorized`.
I'm not sure if this is a PHP problem or a WordPress or maybe it's something in my code I've messed up along the way. Anyway I was curious as to why it appears that way since I would think order of operations would print the first function first, move onto the concatenation, then proceed to the `single_term_title()` but apparently this is not the case. | Try `<?php echo get_the_title(1).': '.single_term_title('', false); ?>`

How to enable Zend Optimiser+ with Batcache

Using a Taxonomy in Two Spots in a WordPress Post
I have a taxonomy called stocks. it has various items such as 'NFLX', 'AAPL', 'GOOG'
I want to be able to assign two things to a WordPress Post:
1. Main stock (only one item selected from the Stocks taxonomy.
2. Mentioned stocks (select one or more items from the Stocks taxonomy).
Here's the other thing, I want the slug for the MAIN STOCK to be in the URL of my post.
Example:
I write an article on Apple Inc and mention other competing companies. The main stock would be AAPL. Mentioned stocks would be AAPL, GOOG, AMZN, etc. And I'd want the URL to be `www.example.com/AAPL/the-name-of-the-article`
So, I'm trying to avoid creating two taxonomies (i.e. Main Stock and Mentioned Stocks) and filling both up with the same set of stocks. Ideally, I want to create one taxonomy and use it in two places. Then pull the slug for that taxonomy item selected for the "main stock" to be used in the URL of the post itself.
Is this possible? | You can do this by using the category taxonomy for your stock symbols, then in permalink settings you would select the custom permalink structure with /%category%/ to get your url of AAPL/article-title.. Then you could use tags for mentioned stocks so you can tag the article with AAPL, GOOG, etc.. You don't even need to setup a custom taxonomy. | stackexchange-wordpress | {

jQuery does not appear to be enqueued on static homepage

How to stop PHP code running when in a child theme
I understand you can add extra CSS on top of the parent theme, but how do you remove PHP code from functions.php?
I want to remove the `Masonry plugin` in `twentyfourteen` theme, and have located the piece of code on `line 254`.
if ( is_active_sidebar( 'sidebar-3' ) ) {
wp_enqueue_script( 'jquery-masonry' );
}
If I'm editing the parent theme, I can just comment this block out `/* */`.
But I'm not aware of a way to change this is my child theme. | You can't actually "remove" PHP code from the parent theme. What you can do is undo things done there.
The counterpart of `wp_enqueue_script` is `wp_dequeue_script`.

add_action( 'wp_print_scripts', 'de_script', 100 );
function de_script() {
wp_dequeue_script( 'jquery-masonry' );
}

Change media attachment author via mysql query
How does one bulk change the media attachment author via an sql query?
I have hundreds of media attachments that need to be moved to another author so the original author can be deleted; but that author has no posts, only media attachments.
(The images were attributed to the author when importing and running a query to take the first post image and make it a featured image.)

`update wp_posts and post_type = ‘attachment’`

Wordpress constantly running out of memory
My Wordpress installation on a shared hoster is constantly running out of memory:
The error pops up at seemingly random, for example when uploading photos or sometimes without doing anything just browsing the Admin area.
It is a very fresh installation (with little content and traffic), I receive this error no matter which Theme and which plugins I use.
I already added these lines to my config:
.htaccess
php_value memory_limit 128M
wp_config.php
define('WP_MEMORY_LIMIT', '128M');
define( 'WP_MAX_MEMORY_LIMIT', '256M' );
My PHP Limit seems sufficient:
PHP Memory Limit:
memory_limit 512M 512M
HOWEVER after all this my memory monitor plugin still says:
WordPress Memory Limit: 40M
Do I have to do anything else to apply these changes? | Try
`memory_limit = 128M`
in php.ini. Your syntax may be wrong.
You can run a function called phpinfo to see what kind of memory allocation you really have. Make a plain text file and call it `phpinfo.php` and put just this line in it:
`<?php phpinfo(); ?>`
then put the file in the root of your server, and then go to that file with your web browser, i.e. mydomain.com/phpinfo.php
You'l see all the php info you need; scroll down for memory settings. If you get an error, that means your web hosting company won't allow phpinfo to run for security reasons.
But that will tell you what the real memory settings are and if your host is being honest. If they are, ask them how to bump memory for your account. If you only see a memory limit of 40 megs, than you're not able to change it due to their restrictions. | stackexchange-wordpress | {

Obtaining the original unchanged Theme
Quite a few months back, I had used a third party theme v 2.9 in my wordpress site. I made a few custom changes to css/.php based on my needs. Now, I plan to upgrade the theme to v3.8.
Before doing that, I wanted to get the diff of changes that I had made to ver 2.9. As I didn't have a copy of the original theme, I contacted the developers of the theme; unfortunately, they also don't seem to have a copy of that.
What are my options to obtain the diff, get an original copy of the theme? Does wp store a copy of original theme somewhere? My site is hosted on bluehost.
Thank You. | WordPress doesn't store a copy of themes.
I see several options:
* Find out why the creator of the theme doesn't have a copy of the theme at version 2.9. It is really weird that any serious developer wouldn't keep a copy of old versions.
* Check your own backups.
* Ask your hosting provider if he has backups.
* How did you get the theme in the first place? Maybe you still have a copy in your Downloads folder or Mail Inbox? | stackexchange-wordpress | {

Can't redirect to previous page after using GET
I have a function that is displaying a shopping cart and products, and so after a product is added (which happens via `GET`) I want it to return to regular domain.
This is the code that updates the cart:
$page = $_SERVER['PHP_SELF'];
// if the product is added to the cart
if (isset($_GET['add'])) {
$_SESSION['cart_'.$_GET['add']]++;
header('Location: '.$page);
// echo 'added';
}

Any ideas? | 1. Do you have `exit();` after the `header(...` ?
2. Do you issue the `header()` before any headers are sent already?
3. If that's a WooCommerce then I believe you are doing it wrong. Instead, you should enable AJAX adding to cart (that's not straightforward on the individual product listings, and you may need to modify the default WC template for that).

Remove Post if Advanced Custom Field is checked to fix paging

CPT: archive-cpt.php VS custom page template
I've created a CPT named `portfolio`. Now i want to create a page which will act as an INDEX for this CPT. Now i've two choices ....
a) Make a custom template having custom WP_Query. In this way i can assign this template to any page and that page will work as an index.
b) Make `archive-portfolio.php` instead, which will act as an INDEX.
Now i've a few questions ...
1: Which is the correct approach?
2: If (a) then what is the actual usage of `archive-cpt.php` page then?
3: If (b) is correct approach, is there any possibility to make this page available in wordpress menu manager by default and also in the drop down menu (located at `Setting->Reading`) to use it as front page? | The correct way is latter one - correctly configure your CPT registration to have post type archive and use appropriate template file for it.
However it gets tricker with your additional requirements.

Custom registration field to SQL database
I have created new columns in a SQL table called `wp_users`. Those fields are "giodo", "handel" and "regulamin".
What I want to do is to add '1' to each column when a user registers and selects corresponding checkboxes.

add_action('user_register', 'myplugin_user_register');
function myplugin_user_register ($user_id) {
if ( isset( $_POST['giodo'] ) )

}
Can I somehow add their values to the database? | > I have created new colums in a SQL table 'wp_users'. Those fields are "giodo", "handel" and "regulamin".
Don't add columns to Core tables. There is no guarantee that these won't be destroyed or corrupted on next update. What you should be using is _user meta_ , and in fact that appears to be what you are actually using:
add_action('user_register', 'myplugin_user_register');
function myplugin_user_register ($user_id) {
if ( isset( $_POST['giodo'] ) )
update_user_meta($user_id, 'giodo', $_POST['giodo']);
}
So the question is a bit confusing.
Your code _should have already_ inserted data into the database, just not where you are trying to put it. Your code should have inserted the data into the `$wpdb->usermeta` table and can be retrieved using `get_user_meta()`. That is what I would suggest. Abandon the attempt to add columns to a Core table and use the user meta API, which is what it was built for. | stackexchange-wordpress | {

Can you have multiple wordpress sites under the same domain?
Any issues with having multiple wordpress sites under the same domain.
Example:
* domain.com/programs
* domain.com/sales
* domain.com/learning

and then I have another person who is the "golf" program admin... \- domain.com/programs/golf
two totally different sites - may use multisite but not sure yet.

**NEW INFO:** To those who said, this is normal for WP and no issues please see Why did installing wordpress in url root jack up underlying WP sites?.
I had 10 sites installed and after installing a "root" site all are having MAJOR permalink issues. | Basically there are two main rules that you have to adjust for to have WP sites across the same domain - not using multisite:
1. For the root I simply put everything in a "home" folder and auto-redirect to xxx.com/home. This fixed the whole root subcategory issue.
2. If you are running IIS and you have multiple WP instances on the same server... And then you turn on URL rewriting (different permalinks) well your entire structure will be jacked up because wordpress names all of its rewrite rule "wordpress" in the web.config file it sets up for URL rewrites. You have to rename the rule manually for each wordpress install. I have submitted this as a bug but haven't heard back from this - suggestion was name should be wordpress plus timestamp.
I will add on if I find more stuff but these are the two big ones. We have 10 WP installs and growing on our main server. Each has a different usage so multisite is a no go. | stackexchange-wordpress | {

How do I change the login logo URL and hover title?
I am trying to change the login logo URL and hover title. I am using the code below but `return bloginfo('url');` and `return bloginfo('name');` aren't outputting the desired `href` and `title`.

Multiple portfolios and single item in two of them (ideas?)
I’m creating a theme at the moment and has come to a point to decide what is the best solution to have implemented for a theme with multiple portfolios.

How do you guys deal with items in multiple portfolios?

<?php $portfolio_name = 'whatever'; ?>
<a href="<?php echo get_permalink() . '?backto=' . $portfolio_name; ?>"><?php the_title(); ?></a>

How to replace settings in WordPress plugin from a theme

How to secure files based on format and word in file name with wp-config or htaccess?
I have a wordpress site that I would like to secure specific files in the uploads directory, so that they can only be accessed by logged in users. The files either have the word "oneperson" or "twopeople" in the filename, and are of the format "zip" or "pdf".
How do I do this? | This is not quite trivial, because natively WP is engineered to completely ignore requests to existing files. So WP doesn't pay attention to files and `.htaccess` doesn't have access to WP's logged in information.
If you look for prior art (in plugins for selling digital files for example) this isn't easily (at all?) doable with direct links. Typically special download links are created and processed by plugins to serve files while masking it's true name/location (which should be restricted from direct access or not in web accessible folder at all). | stackexchange-wordpress | {

Are plugins instantiated on every request to Wordpress?
I want to know how wordpress plugins are instantiated, if Wordpress creates a instance of plugins every time that a request is made to wordpress?
Example. I open /wp-admin: The plugin is instantiated I open /: The plugin is instantiated ... etc | Instantiate in the strict sense is to create an instance of an object from a class. Plugins aren't necessarily class-based, so I'm not entirely sure what you mean by instantiate.
That said, WordPress includes the main plugin file for all active plugins on every front end and admin request. Whether this "instantiates" your plugin depends on where that instance is created (or what you mean by instantiate).
Plugin interaction with WordPress core happens via actions which you hook functions or methods to. Some actions run on both front end and admin requests, others run on only front end or only admin requests, and some can run multiple times within a single request. | stackexchange-wordpress | {

How do the default themes reference style.css?
I was expecting to see `get_stylesheet_uri()` called somewhere in the default header.php file for the default themes (2012-14), but anything like it is missing, which has me wondering how the reference is added.
The default theme headers have something like this:
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>">
<meta name="viewport" content="width=device-width">
<title><?php wp_title( '|', true, 'right' ); ?></title>
<link rel="profile" href="
<link rel="pingback" href="<?php bloginfo( 'pingback_url' ); ?>">
<!--[if lt IE 9]>
<script src="<?php echo get_template_directory_uri(); ?>/js/html5.js"></script>
<![endif]-->
<?php wp_head(); ?>
</head>
Looking at the source for the themes, shows a proper link to the stylesheet in the header, so, how does it get there? | The stylesheet is registered and enqueued by a function called `twentyfourteen_scripts()` in the theme's `functions.php`. Callbacks hooked into the style loader/dependency system will be `echo`ed on the `wp_head` action in the `wp_head()` function.
Which, by the way, is how you should be loading your own stylesheets. There is a similar system for scripts. | stackexchange-wordpress | {

add_action('wp_head', 'dt_specific_enqueues');
function dt_specific_enqueues() {

wp_enqueue_script( 'comment-reply' );
}
} | The parent theme's `functions.php` will load automatically. You don't need to "read" it, and you don't want to "hack" it either manually, which will be overwritten, or programatically, which is very resource intensive.

remove_action('wp_head', 'dt_specific_enqueues');
}

Media sizes aren't being created - server config?
I have 3 sites with WordPress on a RedHat Centos server. Everything were fine until days ago, when I needed to recompile Apache to use mb_string, so I did it using WHM "Easy Apache".
But from then, my sites aren't creating image sizes. I mean, when I upload an image, aditional sizes (already defined on functions) aren't created. If I look inside media folders, only the original file is there, and none thumbnail or extra sizes. When I try to insert media inside posts, no aditional sizes appears on menu.
Any idea on what happened? Thank you all. | It looks like "Easy Apache" handles both Apache and PHP. Only a guess, but you have recompiled Apache/PHP without the needed image libraries-- either `GD` or `ImageMagick`. Without those, the server cannot physically resize images.
You can use a `phpinfo()` script to see if the libraries are present. If not, you will need to recompile-- or whatever that "Easy Apache" system allows-- and make sure the needed libraries are included. Maybe you can add modules one by one using that system. Not sure. | stackexchange-wordpress | {

Changing the wp db prefix after installation?
I have nearly completed a project but forgot in the first place to change the wp_ db prefix on install.

Therefor the question if these described methods still work with 3.8.x or has anything change since then?
<

and have only table and field names to be changed? cuz i also saw a few prefixes starting with _wp_ instead of wp_ ? Best regards Ralf | The basic idea should work-- change the prefix in both `wp-config.php` and in the database itself. What isn't covered would be cases where the prefix is used in other contexts such as when used as part of a "meta" key. Those cases you would need to trace down one by one.
You could also have trouble it the prefix has been hard-coded into anything, but hopefully that isn't the case.
The safe thing to do, if you are able would be to copy the entire database to a database with a different name, and alter the second database. Switching between the two would be a simple edit of the database name in `wp-config.php` and you would have nearly no chance of data loss if you make a mistake, just make sure no one is editing the site while you play with it.

$i = rand(0, count($bg)-1); // generate random number size of the array
$selectedBg = "$bg[$i]"; // set variable equal to which random filename was chosen
?>
Now place this code within `<head>` in header.php
<style type="text/css">
body{
background: url(<?php echo bloginfo('stylesheet_directory');?>/images/<?php echo $selectedBg; ?>) no-repeat;
}
</style>
The path `<?php echo bloginfo('stylesheet_directory');?>/images/`indicates that your random images will be stored within your theme under the directory "/images".
