DB access blocked when initializing WP externally
I have an odd problem I'm hoping the group can help with. The problem is this:
* I have a few situations where I load the Wordpress environment without the overhead of the GUI (details)
* I am able to do this in most environments without a problem but a few (two laptops to be precise) refuse to load Wordpress and instead give me the following error:
!enter image description here
What's so very strange is that:
1. The db connection attributes are correct. This has been validated both by logging in manually from the command-line (using the credentials in the wp-config file); not to mention that this same `wp-config.php` has no problem loading the database when it is loaded normally by Wordpress.
2. The files, OS, PHP version, even the DB connection parameters are all exactly the same on computers that work versus those that don't.
I'm not sure were else to look. Any help would be greatly appreciated. | I accidentally stumbled into the answer today when I forgot to turn on my MAMP managed mysql server. At this juncture it pointed me to the critical difference. This answer is phrased for anyone running MAMP but potentially has broader applicability (certainly LAMP, WAMP, etc.); if you're experiencing the same problem in an non-MAMP environment than these steps may still apply but the explicit directories would not:
* When Wordpress loads normally it looks in `/Applications/MAMP/tmp/mysql/mysql.sock` but when run from the command line it instead looks for the socket file in `/var/mysql/mysql.sock`.
* In order to allow for both execution environments (aka, normal WP and my command-line "include") you just need to create a symbolic link:
ln -s /Applications/MAMP/tmp/mysql/mysql.sock /var/mysql/mysql.sock
* You may need superuser privileges, in which case just add `sudo`:
sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /var/mysql/mysql.sock

Upload PDF and other files from the Front-End
I am trying to create a medical website, where logged-in doctors can actually upload pdfs and other files (such as jpg) from the front-end in posts. Then, after reloading the page, the uploaded files should be retrieved within the same post, so other users can easily find the info, without any access to the back-end whatsoever.
Can this be done in WP?
Thanks in advance!

How to remove CSS file in the header using Wordpress functions?
I want to remove a CSS from loading in the header, this is the code that appears:
<link rel='stylesheet' id='my-css' href=' type='text/css' media='all' />
I tried using these functions but it didn't work:
wp_dequeue_style('my-css');
wp_deregister_style('my-css');
Is there other ways that the above CSS line can be removed without manually editing it in the template?
Thanks. | If your stylesheet is registered and enqueued correctly then...
function dequeue_my_css() {
wp_dequeue_style('my-css');
wp_deregister_style('my-css');
}
add_action('wp_enqueue_scripts','dequeue_my_css');
// add a priority if you need it
// add_action('wp_enqueue_scripts','dequeue_my_css',100);
... should remove it. That only works if the stylesheet was registered and/or enqueued with `wp_register_style` and `wp_enqueue_style`.
If it is not registered correctly then you will have to figure out what your theme did and undo that. It may require editing the template, depending on how the theme is written.

How to disable Multisite sign-up page?
If we try to access a non-existant Multisite site, e.g., ` or ` we are redirected to `
How to block this and redirect the browser to another page? | ### [Update]
An alternative (maybe better) is to use the following constant in `wp-config.php`:
define( 'NOBLOGREDIRECT', ' );

function do_signup_header() {
do_action( 'signup_header' );

Strings including html for localisation
How to localise this string (including html) ?
echo "<div class='updated'><p>All options are restored successfully.</p></div>" ;
Is this correct?
echo '<div class="updated"><p>' . __( 'All options are restored successfully.', 'mytextdomain' ) . '</p></div>';
And how to go about this one?
<p><?php _e( 'On the <a href="' . get_admin_url() . 'import.php">Import</a> page, choose the previously created file and click the <strong>Upload file and import</strong> button.', 'mytextdomain' ); ?></p> | Your example is correct, simply because it works. There are hundreds of ways to localize strings wich are displayed including html, all good and elegant in their own way.
I like to do this as follows:
printf( '<div class="updated">
<p>%1$s</p>
</div>',
__( 'All options are restored successfully.', 'mytextdomain' )
);
You also could do this like:
$str = __( 'All options are restored successfully.', 'mytextdomain' );
echo "<div class='updated'><p>$str</p></div>";
The most important thing is to maintain readability I guess. There isn't a "correct" way to display localized strings in combination with html.
For your second one, I would use:
_e( sprintf( 'On the <a href="%1$s">Import</a> page, choose the previously created file and click the <strong>Upload file and import</strong> button.', get_admin_url() . 'import.php' ), 'mytextdomain' );

Redirect a password protected page?
I'm looking for the simplest way to redirect a password protected page, to another page after entering the password.
E.g.
<?php if ( is_page('name-of-page') && ! post_password_required() ) {

Delete all one-word comments
I'm trying to delete all wordpress comments with only one word. I found this mysql query to delete all comments at once, but that's not what I want to achieve:
DELETE FROM wp_comments WHERE comment_approved = '0' | DISCLAIMER : Not a WordPress Developer, Just a MySQL DBA
If you have privileges to login to MySQL and query data you could collect all the `comment_ID` values that have one word.
SELECT comment_ID FROM wp_comments WHERE
REPLACE(TRIM(comment_content),' ','')=TRIM(comment_content);
You can test this by also seeing the comment_content
SELECT comment_ID,comment_content FROM wp_comments WHERE
REPLACE(TRIM(comment_content),' ','')=TRIM(comment_content);
Using the WordPress API, retrieve those `comment_ID` values and delete them.
Give it a Try !!!

Do I need to include a textdomain if my theme doesn't support translation?
According to the codex
> Themes are required to use theme-slug (or a reasonable facsimile) as textdomain for translation
Does this mean that my theme needs to include a textdomain even if my theme doesn't support translation? ... and also is there any harm in including a textdomain in `style.css` if there are no translation options. | If your code, be it a theme or a plugin, does not support translation, then don’t use the translation functions. And if you don’t use these functions, you _cannot_ use a text domain. :)
There is a very common error that looks like this:
echo __( 'Portfolio' );
_Portfolio_ is not part of WordPress’ core strings, so this code will waste an expensive look-up in the list of translated words without result.
Another side effect is a _partial translation_ when some of these function calls without text domain _match_ core strings. Imagine a navigation where the link to the previous page is in Japanese and the link to the next page in English. This is worse than no translation at all.
So text domains are not your problem, the use of translation functions is important. | stackexchange-wordpress | {

wp_list_pages - Using a Walker to customize output order
I'm using wp_list_pages to create a navigation menu. I've run into a challenge with the menu order, though, and I am trying to figure out a way to take more control over the order of the menu.
Is it possible to customize the order of the wp_list_pages output using a Walker?
For example, I'd like to check if a given page in wp_list_pages results has a `post_meta` value of `page_x` and output that _first_ , then do the same for another page, then, if none of the rules match, continue as normal. | `wp_list_pages( $args )` calls `get_pages( $args )`. You can filter the `get_pages()` output with a filter on `get_pages`.
Let’s say you call `wp_list_pages()` like this:
wp_list_pages(
array(
'please_filter_me' => TRUE
)
);
You can sort the pages now with code like this (not tested):
add_filter( 'get_pages', function( $pages, $args ) {
// not our query
if ( empty ( $args['please_filter_me'] ) )
return $pages;
$out = $top = array();
foreach ( $pages as $page )
{
if ( get_post_meta( $page->ID, 'my_key', TRUE ) )
$top[] = $page;
else
$out[] = $page;

WP_Query pulling an extra post per page

'post_type' => 'post',
'posts_per_page' => 20
);

<?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
<li><?php the_title(); ?></li>
<?php foo_pagination(); ?>

'post_type' => 'post',
'posts_per_page' => 20,
'ignore_sticky_posts' => true
);

Using esc_html with HTML purifier and CSSTidy: Overkill?

How can a 'scripts' directory be hooked into wp_head();?

Hook to main query with filters based on custom fields

Stop WordPress Entirely and Run My Own Code

I tried just putting everything in my `index.php` file and include everything manually from there. However, this results in the `<head>` of my page being loaded within the body. So it's obvious that I need to interrupt WordPress before it can run `wp_head()`, but don't know how this might be done. | You could hook `init` and check the current blog ID

Display Today's date outside the loop?
Is there any way to display the Today's date outside any loop/post using WordPress date/time function instead of using the PHP `date()` function? I'm using the PHP `date()` function but it does not translate the date (month/day names) in the local languages, so it is not possible to translate it without changing the PHP code and setting the locale etc. | Use `date_i18n()` from `wp-includes/functions.php`.

* If the locale specifies the locale month and weekday, then the locale will

Theme Checker Text Domain
`$output .= '<li class="recentcomments">' . sprintf(_x('%1$s %2$s - %3$s %4$s', 'thst'), get_avatar( $comment, 48 ), (...);`
This is my line of code and Wordpress Theme Checker tells me "Text domain problems. You have not included a text domain!" I have included one though, as you can see. What could be the problem here? | `_x()` is for string with a context. So your second argument is just the context, and there is no text domain.

$string = _x(

'recent comments 1 = gravatar, 2 = … ', # context for translators
'thst' # text domain

Setting get_queried_object
I know that `get_queried_object` contains the object that was queried for the current page. My question is, what methods of querying affect the contents of this?
For instance:
* `query_posts`
* `get_posts`
* `get_post`
* `new WP_Query`
* etc. | As per its laconic source:
function get_queried_object() {
global $wp_query;
return $wp_query->get_queried_object();
}
This function retrieves object from main query. As such it is affected by anything that changes main query. From your list that would be `query_posts()` (reason number umpteen it should not be used). | stackexchange-wordpress | {

Check If posts exist in custom post type category, outside of loop
I'm building a navigation, outside of the main loop, that includes drop downs. I have a custom post type called 'Events', that has its own categories. I would like there to be a drop down if there are posts within that custom post type and category, but I'm not sure what functions I should be using to determine this...
I have...
$hasposts = get_posts('post_type=Events&category=40');
if($hasposts) {
..// show the drop down menu
}
Should I even be using `get_posts()`? Everything I am getting returned has an empty array, but I know that some of those categories include posts...
Many thanks, WA. | It all boils down to WP_Query in the end even if you use get_posts, here's my modified version:
$hasposts = get_posts('post_type=sc-events&category=40');
if( !empty ( $hasposts ) ) {
..// show the drop down menu
}
or
$query = new WP_Query(array(
'post_type' => 'sc-events',
'category' => 40
));
if( $query->have_posts() ){
echo 'we have posts';
} else {
echo 'no posts found';
}
While this will work, there's an alternative inspired by your own answer that uses the category slug rather than its ID:
$term = get_term_by('name', 'whatever category 40 is called', 'category');
if($term != false ){
if($term->count > 0 ){
// we have posts

How to publish page that can't be detected by search engines?
I like to publish drafts in my 'Uncategorized' category. This category is not linked anywhere on my site. It's great for allowing contributors to an article to read the draft before it is made public. The problem is that after just 2 or 3 days, search engines begin picking up the draft and people start posting comments.
I don't want to password protect the draft. Is there some way to hide it from search engines while it is in the 'Uncategorized' category? | How about something like this on your `functions.php`:
add_action('wp_head', 'no_robots_on_uncategorized_posts');
function no_robots_on_uncategorized_posts() {
if(in_category('uncategorized')) {
wp_no_robots();
}
}
This will output the following line of code on the header of your 'uncategorized' posts:
<meta name='robots' content='noindex,nofollow' />
What this means is that even though search engines will see the page, they will be told to ignore it and don't show it on their results. | stackexchange-wordpress | {

Add a css class to a taxonomy permalink
I need to add a css class to every `<a>` element retrieved by `the_terms()` (or similar function) in order to open the taxonomy permalink in a fancybox modal window. I've been searching this whole afternoon for a Filter that could handle it, with no success.

$cities = get_the_terms($post->ID, 'cities');
foreach ($cities as $city) {
echo '<a class="fancybox" href="'. get_term_link( $city->slug, 'cities' ).'">'.$city->name. '</a>' ;

How to: get_user_meta - BuddyPress

Also, it's best practice to use `bp_get_user_meta()`, because it works better with certain kinds of BP plugins (multi-network, etc).
Thus:
if ( bp_has_members() ) {
while ( bp_members() ) {

Redirection based on location but without affecting search bots
A client has a successful UK site based powered by Wordpress and is launching a US arm. While the US sub-sites are built, he has a holding page that is visible to US visitors, who are redirected to it from the usual home page by the Geo Redirect plugin.
I've just realised that Geo Redirect is also redirecting Google's (and other search engines') bots, which is not at all good; does anyone have a relatively easy solution that would do what Geo Redirect does so well but would not affect visits by search engine bots? | **Search**
Help Google to determine the site language and to serve the right page for the users in different countries. Mark up language attributes correctly. Use `<html lang="en_UK">` and `<html lang="en_US">`. Use `<link rel="alternate" hreflang="x" />` in page `<head>`. It's also important to specify site targeting in Google Webmaster Tools.
**Referrers**
I believe people residing in UK will link to your UK-targeted site, not US-targeted. And inversely.
**User Experience**
It's always a good practice to leave the user the ability to choose preferred site himself.
**Advice**
Don't use any redirection plugins. Google advise sounds the same:

remove_action in a theme

wp_get_attachment_link() add rel attribute if the link points to direct image

How can I autopopulate titles in the media library?
I have hundreds of images in my media library, most have which have no titles. In the media library, the "(no title)" message is displayed along these images.
Since I generally have one image per post, I would like to auto-populate the library titles, by grabbing the associated post name. I don't mind if I overwrite some existing titles.
Does anyone know of a hack that will do this?

Help plz | It sounds like you change the configuration on the local server. You need to put it back. that local configuration information needs to remain unchanged if you intend to continue working on the local copy, which you should.

The easiest way to sort this out is to add the following two lines to your `wp-config.php` file on your local server.
define('WP_SITEURL', '
define('WP_HOME', '
Obviously, the domain needs to be changed-- probably to `localhost` but if the local server has a static (internal) IP using the xxx.xxx.xxx.xxx IP is better.

Why is this function crashing my wordpress installation?
I'm new to wordpress and programming in general. For my first site there is a custom template in which I want to load a javascript library. After registering and enqueueing it in functions.php my site no longer loads properly. I'm sure what it is simple mistake and would really appreciate a little help. For the record, I'm using a child theme of twentytwelve.
Here is the code:
<?php
function load_wforms() {
if (is_page(45)) {
wp_register_script('wforms', get_stylesheet_directory_uri().'/js/wforms.js'), false, '2.0');
wp_enqueue_script('wforms');
}
}
add_action('init', 'wforms');
?>
Thanks! | First, be sure to enable `WP_DEBUG` in your `wp-config.php` file, so that you can see fatal error messages.
In this case, the problem is that you've named your function `load_wforms()`, but you reference the callback `wforms` in your `add_action()` call:
function load_wforms() {}
...vs...
add_action('init', 'wforms');
The second parameter, `wforms`, refers to a function named `wforms()` \- but your function is named `load_wforms()`. Change your add_action to this:
add_action( 'init', 'load_wforms' );
(Side note: you should enqueue scripts at `wp_enqueue_scripts`, rather than `init`.)
## Edit
Also: fix the syntax error as noted by @milo in his comment:
wp_register_script('wforms', get_stylesheet_directory_uri().'/js/wforms.js'), false, '2.0');

I doubt that the Theme developer intends for the `/function-includes/theme-functions.php` file to be overridden by a Child Theme. Functional files are usually a core component of the Theme, and allowing a Child Theme to override them wholesale would introduce serious development complexity into the Theme.
Rather than ask for a functional file to be able to be overridden by a Child Theme, I would instead ask the developer to make custom function output _filterable_ , or (where appropriate), to make some custom functions _pluggable_ (by far, I prefer filterable function output to pluggable functions). | stackexchange-wordpress | {

WordPress Theme activation hook?

How would I use a media query to make my entire theme responsive or fluid?
I've settled on a theme for one of my blogs. Is it possible to just wrap your stylesheet (style.css on most themes) in @media queries, and make your entire theme **responsive** , or **fluid** , so it **works well on all browsers and screen resolutions**?
If so, does anybody know how I can accomplish this? Or is there a better, easier way to accomplish this?
I mean, can I just put this at the top of my style.css?
@media screen and (max-height: 700px) {
// style.css rules
and of course at the very bottom, just:
}
Will this make my entire theme fluid or responsive, or is it much more in-depth than that? Any guidance in this regard would be greatly appreciated! | You can use media queries to change the styling per element depending upon specifications. You would have to add these to the bottom of your stylesheet, so that it overwrites your default styles depending upon the screensize
This following media-queries template from bootstrap is only based on screen size. You can use more complex media-queries to target specific device as well.
To Support older browsers (IE), you'd have to use conditional statements to include respond.js or media-queries.js . Media queries will only work with device specifications such as screen, handheld etc...
A great place to start is: <
Eg: Bootstrap Media queries. /* Large desktop */ @media (min-width: 1200px) { ... }
/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }
/* Landscape phone to portrait tablet */

/* Landscape phones and down */

Add_image_size not cropping
I want to make a crop on the images of my blog page that have more than 443px adjust it to 645x443 size, exactly.
I used this code:
add_theme_support ('post-thumbnails');
add_image_size ('blog-page', 645, 445, true);
However, the image is resized instead of making the crop.

WordPress does not zoom. It only crops. If you want an image to have a custom intermediate size, then you must upload an image with dimensions greater than or equal to the dimensions specified in your `add_image_size()` call.
Also: if you have uploaded images prior to adding your `add_image_size()` call, then you will need to regenerate your intermediate image files in order for WordPress to create images using your custom size. | stackexchange-wordpress | {

Thumbnail with different sizes
I want make all my blog thumbs the size of 227x133. I need images width have 100% (for responsive design). Some images have width greater than the other and vice versa.
I'm using this code to show the thumbs of my blog:
/ / Post thumbnails sizes
add_theme_support ('post-thumbnails');
add_image_size ('blog-page', 9999, 545, true);
The problem is that the images are not the same size as each other:
How is: <
How I want: <
What's wrong? | Intermediate image sizes are discrete, not variable. When you define an image size, with specific dimensions (whether hard-cropped or box-resized), WordPress will create a discrete image, with the specified dimensions.
Otherwise, if width could be defined dynamically, WordPress would have to create a prohibitively large number of images, just to account for responsiveness.
To account for responsive design, you'll have to use CSS. The easiest way to do so is using a rule similar to the following:
#content img {
max-width: 100%;
height: auto;
}
That way, if the #content div is resized, your post images will be resized along with it, while maintaining their aspect ratio. | stackexchange-wordpress | {

Do I need to use The Loop on pages?
I'm writing my first WordPress theme and have a question about the use of The Loop in page templates. The page templates I've looked at all follow basically the same pattern (example from Twenty Twelve):
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', 'page' ); ?>
<?php comments_template( '', true ); ?>
<?php endwhile; // end of the loop. ?>
But a page will only have one post associated with it so iterating through the posts seems unnecessary. My page template is more readable and seems to work fine:
<?php
the_post();
the_title('<h1>', '</h1>');
the_content();
?>
Is this a good practice? Are there any downsides? | According to the Theme Guide, full loops should be used, even on single templates.
> Full loops must be used in all templates. Just calling `the_post()` in a template like `single.php` or `page.php` is not enough.

order by meta_value serialized array
Hi I'm trying to pull posts using the wp query. Just one problem--I am trying to sort the posts alphabetically by a certain meta_value. Thing is that this meta_value is a serialized array. Is there an easy way to do this without having to unserialize it? Thanks!
a:1:{i:0;a:1:{s:7:"people";s:16:"Tanya Garca";}}
Btw, I cannot change the way the meta_value is being saved because I am using this plugin which automatically saves it serialized. | > Is there an easy way to do this without having to unserialize it?
Not in any reliable way. You can certainly `ORDER BY` that value but the sorting will use the whole serialized string, which will give you technically accurate results but not the results you want. You can't extract part of the string for sorting within the query itself. Even if you wrote raw SQL, which would give you access to database functions like `SUBSTRING`, I can't think of a dependable way to do it. You'd need a MySQL function that would unserialize the value-- you'd have to write it yourself.
Basically, if you need to sort on a `meta_value` you can't store it serialized. Sorry.
If you can't change how the value is stored you will need to pull your posts, loop through them to sort them, then loop through them again to display the sorted results. | stackexchange-wordpress | {

wordpress loop and template files
I am curious how WordPress know that if I have a category.php and do the basic loop inside there that when I click on category A I get all of A's posts. The reason I ask, is because I have seen themes that just have an index.php and when you click on Category A in those themes you get all of A's posts, and they do not have a category.php file.
Is there a trick to achieve this?
because if you do:
category.php and inside that do:
if(have_posts()){
while(have_posts()){
the_post();
}
}
You will get all posts for any category link you click on. How ever, as stated some people only have index.php in their theme and when you click on a category link you get all posts for that category, regardless of category clicked on.
Much like global post_id is there a global category_id to query against? | If you look at the template hierarchy for categories you will see it follows:
1. category-{slug}.php
2. category-{id}.php
3. category.php
4. archive.php
5. index.php
As Milo says these templates are just using the loop to display what is already queried, so there template itself does not matter outside load order of the hierarchy. | stackexchange-wordpress | {

How can I style an IFRAME element that has a constantly changing class name?

WP_Query: Fetch posts that are in (category1 and not in category2), OR posts that are not in cagegory1
I have two categories that will always stay the same. They are called "Events" and "Show on frontpage". The latter is a child category to Events.

- post is in Events but NOT in Show on frontpage: Don't fetch post
- post is in Events AND in Show on frontpage: Fetch post

Bloginfo hook - can it be more precise?
From the codex, regarding filter hooks:
bloginfo_url
applied to the the output of bloginfo("url"), bloginfo("directory") and bloginfo("home") before returning the information.
Is there a way I can specify that a bit more precise? So that I can hook something only to `bloginfo("url")` for example? | You can access that, using the additional variable in the Filter Functions.
The Filter `bloginfo_url` uses the `$show` parameter (the parameter you use when calling `bloginfo`) and passes it to `apply_filters`.

add_filter('bloginfo_url', 'f711_bloginfo_url_filter', 10, 2 );
It tells you where you hook into, the callback function, the priority in which it is applied compared to other filters, and the number of arguments that can be passed to the function. This is your important part, as 1 is the standard value.
In the Callback Function:
function f711_bloginfo_url_filter( $output, $show ) {

and how I am fetching the email.
`$email = $wpdb->get_var("SELECT user_email FROM wp_users WHERE billing_phone = $phone_number ");`
Thank you all in advance. Any help is appreciated. | If you have `billing_phone` as user meta, which is the preferred way, that query would be incorrect. The advantage of utilizing custom user meta and adding a field for `billing_phone` would allow you to use `get_users()`.
$user = get_users('meta_key' => 'billing_phone', 'meta_value' => $phone_number, 'fields' => 'ID');
The above would give you an array of User IDs that have the matching `billing_phone` meta value. | stackexchange-wordpress | {

Posts being viewed

How to Display Frontend CSS for Administrator only
I've been asked to restyle the css of a WordPress website frontend. The website can't be in maintenance mode while working on it as it must stay up and running all the time. I assume that if I can add a small and unobtrusive condition in the header allowing the administrator to see a different css file than the users, I could edit the css and test the result while the users still see the original version of the website. This way I could work on the design without anyone noticing.
Can anyone tell me which WordPress function I should call on the header to switch the css file if and only if the user is an administrator?
The best would be not to edit the "functions.php" file or activate any plugin as I really don't want to mess with the website as it is (few chances but chances anyway). I would rather edit the "header.php" file in the theme folder in order to be sure nothing bad happens.
Thank you. | You should be able to simply check the capabilities of the currently logged in user. If they're an administrator the following example should do what you want it to. Just add this into your theme's functions.php file.
Please note this code is untested, but it should get you where you want to be. If the level_10 capability doesn't work you can check out the documentation for other user levels and capabilities here.

Removing Submenu from Menu
Thesis appears to automatically add the sub-menus (sub-menu ul) to menu parents if childs exists. I have a specific need to remove this html from a particular menu.

Not sure if there a hook to do this.

'depth' => 2, // how many levels to show
// prolly some other stuff here
));

Get all posts containing a shortcode
I'm writing a WP plugin that involves using shortcode. One of the missions is to display all (publish) posts that contain my shortcode regardless of their post type. Is there a built-in function for this?
Thanks in advance. | WordPress isn't aware of your shortcode until it's rendered on the front end. So when WP sees it in the content and replaces it, that's when it's aware that your shortcode exists. It also promptly forgets about it afterward, of course.
So there's no built in function to do what you're asking. The best you can do is probably write a `LIKE` query which may or may not be a good idea.
<?php
function wpse87582_find_shortcode_posts()
{
global $wpdb;

Most Wordpress sites causing realpath errors
recently installed some debugging software on our server and realised that most errors are coming from realpath() in Wordpress sites.

Autosort uploads in galleries by filename

Gravity forms - Can I have multiple custom spinners?

add_filter( 'gform_ajax_spinner_url', 'cwwp_custom_gforms_spinner' );
/**

*
* @since 1.0.0
*
* @param string $src The default spinner URL
* @return string $src The new spinner URL
*/
function cwwp_custom_gforms_spinner( $src ) {
return get_stylesheet_directory_uri() . '/assets/img/css/newsletter-loader.gif';
}

// other identifiers would probably be better and won't rely on global $post

WP_Query: query posts by ids from array?

get_the_excerpt() with fallback like the_excerpt()
You know when using `the_excerpt()` and no "excerpt" is set on a post it automatically uses the first 50 words or so.
Is the same also possible when using `get_the_excerpt()`
For instance I'm using `get_the_excerpt()` like this …
$return .= sprintf('
<li>
<div class="title"><a href="%1$s">%2$s</a><span class="goto">a</span></div>
<div class="project-description">%3$s</div>
</li>',
get_permalink( get_the_ID() ),
get_the_title(),
get_the_excerpt()
);
However if no excerpt is set, the `get_the_excerpt()` function doesn't show a fallback (the first 50 or so words). Any idea how to make that work? | The function `the_excerpt()` is only a echo of the function `get_the_excerpt()`:
function the_excerpt() {
echo apply_filters('the_excerpt', get_the_excerpt());
}
If you like a fall back for no input the excerpt meta box, then create a text from the content - `get_the_content()`. You can use the core function `wp_trim_words()` for set the counter for words and easy to set a text from all content. A example:
$excerpt = get_the_content();
$excerpt = esc_attr( strip_tags( stripslashes( $excerpt ) ) );
$excerpt = wp_trim_words( $excerpt, $num_words = 55, $more = NULL ); | stackexchange-wordpress | {

using 1 form shortcode (si or cf7) for all multisite sites
I have a network with more than 50 sites. I want to create one contact form (which means one shortcode) using contact form 7 or fast secure contact form. Then, I want to use that shortcode on all the 50+ sites so all sites use the same form.
The problem is that when I try to use a shortcode of site A over site B, it's not working.
Do you know how can I use a contact form shortcode globaly on all sites at once?
Thanks! | A Must Use plugin could do the work.
This is just an outline and has to be fully tested:
add_shortcode( 'global_form', 'shortcode_wpse_87634' );
function shortcode_wpse_87634()
{
// Main site, ID=1, that has the form
switch_to_blog( 1 );
// Do your stuff
$my_stuff = something(); // maybe do_shortcode
// Back to original site
restore_current_blog();
// Return shortcode content
return $my_stuff;
}
Also, maybe the contact form plugin must be Network activated for this to work.
Having the shortcode available Network-wide will work with the `mu-plugin`, but to have the form really working globally, that's another issue. | stackexchange-wordpress | {

Caching of SQL queries
Within one plugin file I have several calls to the same option in the database via get_option(). Does WordPress do a database query every time I use get_option()? Would it be better to get the option once and store it in a global variable? | Wordpress will only do a database lookup the first time if the option hasn't been auto-loaded or already accessed prior. The performance hit is negligible, however if you're loading multiple separate options with a bunch of get_options instead of using the serialised option functionality, then the initial lookup * X number of separate option rows could potentially cause performance issues.
