Inherit plugin settings to new site in Multisite
I use the Breadcrumb NavXT plugin for a WP Multisite. I activated the plugin for all sites so I can use it throughout my network.
My problem is that every time I add a new site I have to change the default settings of the plugin, but I’d like WP to use the settings I already customized for the main site because on all future sites they would be the same.
Is there a way to force WP adopting the plugin settings of the main site? | Nice Question!
But I'll leave for the asker and for the reader the task of **finding the plugin options name**.
This can be used for any plugin/theme that relies in a _single/serialized_ value in the `wp_options` table. If it's not a single value, it's another task...
In this example, I'm using WP-Pagenavi `option_name`.
!wp-pagenavi option name
_Action hook found inside the function`wpmu_create_blog` in the file `/wp-includes/ms-functions.php`._
add_action( 'wpmu_new_blog', 'wpse_70977_copy_main_site_options', 10, 6 );
function wpse_70977_copy_main_site_options( $blog_id, $user_id, $domain, $path, $site_id, $meta )
{
$mainsite = get_option( 'pagenavi_options' );
switch_to_blog( $blog_id );
update_option( 'pagenavi_options', $mainsite );
restore_current_blog();
}
This code is tested with the plugin being activated on a per site basis, and with the plugin being Network Activated. | stackexchange-wordpress | {

prevent caching during tinymce custom button development
I'm following this turial on how to add a custom button to TinyMCE editor in WordPress. Trying to edit author's JS to include my functionality, yet it seems to have gotten cached. Article author has a hack for it (code snippet below), and it did work for the first time (the button is in the toolbar now), although it doesn't work for subsequent refreshes.

$ver += 3;

}

Removing custom post type from link search results
I have created a custom post type and disabled it from appearing in search results. However when I add a link from a normal post, I still get these entries from my custom post type available to link to in the internal linking box (at the bottom when of the popup when you click the link button in the editor). How can I disable the custom post type from displaying entries there as well? | I suggest making it private (`'public' => false` when registering the post type).

Apply permissions per post
We have a WordPress site where we have external authors for whom we have created usernames at the `Editor` level. We want these editors to be able to create new posts and modify their own posts, but occasionally we have posts in progress that we'd rather keep more private.
It is a very small pool of users, and an even smaller number of posts to "protect," so I am okay with any technique that requires explicit GRANT for our own users or explicit DENY for the external users. DENY would be easier of course, but I am not going to get fussy. | If you look at Wordpress's explanation of Roles and Capabilities, you will see that the correct role you should have assigned them is Author.
That being said, if you for some reason don't want to change them to Authors, you can alter the capabilities that a role has. See the full list of Editor capabilities here.
remove_cap( 'editor', 'read_private_posts' );
remove_cap( 'editor', 'edit_private_posts' );
remove_cap( 'editor', 'delete_private_posts' );
This will permanently remove that capability, so after the wp-admin of the site is loaded once, you can remove these lines or comment them out. | stackexchange-wordpress | {

How to speed up my site
> **Possible Duplicate:**
> Steps to Optimize WordPress in Regard to Server Load?
I've got a WordPress site with a few plugins installed, and it takes a long time to load.
I'm concerned about this; I don't want visitors just giving up and leaving, also Google takes page speed into account in its Page Rank.
Is there a way I can speed up my site without removing any of my plugins? | Try using a caching plugin. There's plenty available, the two most popular being WP Super Cache and W3 Total Cache. If you're just starting out with caching, I'd recommend W3 Total Cache, as it is rather easy to set up and includes a lot of options. It's even used by some of the bigger sites such as iPhoneClub.nl, The Next Web, and Digital Trends. [source]
Normally each time someone visits your site WordPress has to dynamically build the page by making database queries and loading theme template files. A caching plugin saves the output as a static HTML file, and serves that to your visitors instead. Each time you modify your site or write new content, you need to empty the cache and the plugin will start building HTML files again. This saves a great many database queries and requests.
One last thing: if you have restrictive resource limits, or you happen to use the BuddyPress plugin, I would instead recommend Hyper Cache, as it's specifically built for that purpose.

Clean install - Changing permalinks in twentyeleven give 404
interesting problem that I encountered, not sure if it's bug or not..
On a clean install using the **twentyeleven** theme I try changing the _Permalink Settings_ to something different from the _Deffault_ and every post starts giving Page Not Found 404. The Pagination and the top Nav Menu also stop working.

Change featured image urls in database
Im storing my images on another server and Ive managed to change the urls in the database but I cant seem to change the featured image urls?

UPDATE wp_posts SET guid = REPLACE (guid, ' ' WHERE post_type = 'attachment';

In fact, chances are that you've got a lot of image/media urls in that table, which you haven't changed.

I would suggest using something like Velvet Blues Update Urls.
It looks like you have changed all of your URLs and not just the image/media URLs. Is that what you intended?
Also, you should never change the guid.

Does WordPress Change the .htaccess File When Updating?
I've just implemented a new WP website, replacing an older hardcoded HTML site. I will be adding 301 redirects in the `.htaccess` file to point the old URIs to the new WP Permalinks.
My questions is, as WP generates the `.htaccess` file initially (at least on my install it did) will WP overrite the `.htaccess` file when I update WP in the future?
Further to the above, is there any time, including the update as mentioned above, that WP may overwrite this file and if so is there a way to prevent that?
I've searched high and low and can't seem to find a straight answer.
Any help would be appreciated.
Thanks! | Generally speaking WordPress will update the .htaccess file any time you change the permalink structure. Many plugins will also update/modify the file as needed.
But the default structure of the .htaccess file allows you to lay it out in such a way that WordPress will not overwrite your custom entries.
WordPress will overwrite the entries between '# BEGIN WordPress' and '# END WordPress'. While most plugins will create their own begin and end tags and only update within those tags.
Simply put your custom entries outside of any custom tags/comments and they _SHOULD_ be preserved when WP updates the file. | stackexchange-wordpress | {

wp_remote_get vs. fetch_feed ? which is the better for performance?
I m trying **to share my web site contents** for other web sites using by external loop file or rss file.
when i asked some questions about `wp_remote_get` function ; @Serkan suggest to me , using `fecth_feed` methot / function etc. (check the question here.)=
I really confused , which one i should, which one is better way for high performance, could anyone explain it why ?
Thanks. | Neither are high performance, and they do different things.
`fetch_feed` is for grabbing feeds RSS feeds etc, `wp_remote_get` is for grabbing arbitrary items.
Neither are fast, and the performance difference between each is negligible or irrelevant, but technically `fetch_feed` is slower than `wp_remote_get`, not because it's faster or slower at grabbing over the network, but because it uses SimplePie to parse the feed ( which you'd end up using anyway if you used `wp_remote_get` on a feed ).
So even using `wp_remote_get`, you'd get the Feed in the same amount of time, but then you'd have to write the code to process it afterwards, and I'm sure the SimplePie people will be faster as they've had more time to optimise and test than you.
So if you're grabbing an RSS or Atom feed, use `fetch_feed`
If you're grabbing html files, images, or other files, use `wp_remote_get`

Can't understand why sometimes a [caption] field appears
I'm trying to make a php script which, given a post id, returns post content. I'm not the one who writes articles, I'm just operating on a wp site. Post content is for an app of mine which has to parse it.
My script is very simple:
<?php
require_once("wp-load.php");
if(isset($_GET['id'])){
$post_id = $_GET['id'];
$queried_post = get_post($post_id);
echo $queried_post->post_content;
}
?>

other times I have just the image
<img ...ecc
why is that? Is there a way to force the same output regardless of who has written the article? | The `[caption]` part shows up because one of your authors/editors added a caption to the image when it was inserted into the post. You will have this problem not only with captions but with any other shortcodes that your authors/editors use. And you should be aware that WordPress includes several in its Core but various plugins and even themes provide a lot of them. You will need to process the shortcode:
echo apply_filters('the_content',$queried_post->post_content);
Or strip the shortcodes:
echo strip_shortcodes( $queried_post->post_content );
Which you do depends on the results that you want.
You should also be aware that echoing raw post content-- ie. `$queried_post->post_content`\-- will probably not give you the formatting that you expect, because raw post content is not typically complete markup.

include shortcode values in Thickbox form
I have a shortcode that is built using a Thickbox form with various inputs that return the values. This works fine. However, I would like the existing values (if present) to re-populate the form if the user opens it again.
**Here is an example of my shortcode:**
`[schema type="person" name="Andrew Norcross" description="I make interwebs" ]`
**I have a working jQuery match function to find the shortcode if it exists:**
`var code = $('div#wp-content-editor-container textarea').text().match(/\[schema(.*)\]/g);`
the code above does get the entire shortcode as a string, but I'm at a loss for how to process it efficiently to get the values I want.
**so what I want to accomplish:**
1. check for a specific part inside the shortcode data (i.e. name="Andrew Norcross")
2. get the value inside the quotes and insert it into the field on the form
I've tried a few ways but nothing seems to function as expected. | Try something like this...
var code = $('div#wp-content-editor-container textarea').text().match(/\[(schema.*)\]/);
code = '<' + code[1] + '>';

How to get grandparent of a given category
Just wondering what the best way to get the top-most level category (grandparent) of a given category assuming it has one?
Example structure:
Operating Systems \- Mac \- - Mountain Lion \- Windows \- - Windows XP
I want to be able to somehow get the ID of the "Operating Systems" category from within the Windows XP category.
Any suggestions? | You could write a simple function to do this each time you need to. Here's an example I found on this website.
function pa_category_top_parent_id( $catid ) {
while( $catid ) {
$cat = get_category( $catid ); // get the object for the catid
$catid = $cat->category_parent; // assign parent ID (if exists) to $catid
// the while loop will continue whilst there is a $catid
// when there is no longer a parent $catid will be NULL so we can assign our $catParent
$catParent = $cat->cat_ID;
}
return $catParent;
}
Then you can use this function anywhere like so:
$catid = get_query_var( 'cat' );
echo pa_category_top_parent_id( $catid );
Reading the comments in the code it is pretty self-explanatory. Hope this helps. | stackexchange-wordpress | {

How to pull user/author profile data in a plugin?
My site has a user profile page. For some reason I would like to pull user profile data in my plugin.

For example I would like to get displayed profile user id.
Can anyone tell me how to pull it.? | If you're trying to get user data for the displayed profile, you can do it like so:
`$thisauthor = get_userdata(intval($author));`

`$thisauthor->ID`

What is the scope and persistence of add_filter() and remove_filter()?
I understand that using add_filter() or remove_filter() directly within a themes' functions.php would make the changes global across the theme unless you override them elsewhere. But believe this is a result of WordPress initialization.
add_filter( $tag, $function_to_add, $priority, $accepted_args );
However if a call to add_filter() or remove_filter() is made within a function or class:
function example(){
...
add_filter( $tag, $function_to_add, $priority, $accepted_args );
...
}
What is the scope and persistence of the change? | It is always global. `add_filter()` and `add_action()` are just wrapper for the global variable `$wp_filter`. So it doesn’t matter where the function is called.
The same is true for `apply_filters()`, `apply_filters_ref_array()`, `do_action_ref_array()` and `do_action()`: they work in the global namespace, that’s the reason why the callback handlers (functions or methods) have to be public. A protected class method cannot be called from the global scope. | stackexchange-wordpress | {

How to disable `SQL_CALC_FOUND_ROWS`

In the site I'm trying to optimize, I noticed several queries that are rather slow and start with **`SELECT SQL_CALC_FOUND_ROWS`**
Searching this site, the relevant question **wordpress query causing load** has no adequate answer, in my opinion.
Can I somehow disable `SQL_CALC_FOUND_ROWS` without breaking too many things - if possible breaking nothing? It seems that pagination relies on this.

Add Option if Not Exists
I need to see if an option, and if does, get the value. If not, I need to add it.

<?php
$option_name = 'myhack_extraction_length' ;
$new_value = '255' ;

$deprecated = ' ';
$autoload = 'no';

}
Which supposedly **updates the option name myhack_extraction_length with the value 255. If the option does not exist then use add_option and set autoload to no.**
However, it seems to me that the second half could be called in two ways, if the option does not exist OR if the new value==the option
Is this correct? | The logic on the IF THEN ELSE does seem a bit wonky. If I'm reading it correctly...
The call to get_option( $option_name ) will return FALSE if the option does not exist or if it has no value.
So the _IF_ would be executed:
1. when the option doesn't exist and $new_value != FALSE
2. the option has no value and $new_value != FALSE
3. the option exists and has a value that is != $new value
The update_option() call would then update the value or create the option with $new_value.
The _ELSE_ would be called if:
1. the option exists and has the same value as $new_value
2. the option does not exist and the $new_value == FALSE | stackexchange-wordpress | {

How to get all post except particular category without breaking the paging
I'm trying to get all post except particular category this works fine but it cause the pagination button/link to render the same posts again on page 2, 3, 4 and so on not rendering the older post. Here is how I am trying to exclude a particular category
<?php query_posts('cat=-22');?>
This excludes the category but prevents pagination buttons/link from showing older posts, instead it shows the same first 5 posts as on page 1.

$query->set( 'cat', '-22' );
}

> PG — Possibly offensive, usually for audiences 13 and above
>
> R — Intended for adult audiences above 17
>
> X — Even more mature than above
What would be a good way to add such feature? Ideally, on the post page, there is an area with radioboxes where the writer can make their selection. There must be a way to echo the choice in the post template.
Please provide code example if you choose to answer as my coding knowledge is limited. | Custom field will do the task. On the post page there's nothing to do great, just create a Custom Field called agerating or age-rating. Authors will enter the value of the field according to their content with G/PG/R/X.

<?php $age-rating = get_post_meta($post->ID, 'age-rating', true); ?>
Now use this code to show the rating:
Rated As: <?php echo $age-rating; ?>

</ul>
<?php do_action('woocommerce_after_shop_loop'); ?>

Custom Post Type with image gallery
I'm doing research on custom post types for a Wordpress site I'm going to be putting together for a client of mine. The basics of the Custom Post Type seem pretty straight forward. What I'm trying to determine is the best way that I could have an image gallery as part of my custom post type.
For example, a custom post type would be a car. In addition to the details of the car (make, model, year, mileage, etc.) there will be 1-n images associated with it that should be part of the post (modified inside the post, removed along with the post, etc.) Ideally I'd want thumbnail images that open up to a lightbox of some sort.
Hopefully this is something that can be accomplished without totally hacking up Wordpress. | Custom Post Types can have image attachments like other post types. A simple way to display them is via the gallery shortcode. There are several plugins out there to enhance the gallery output, or you can also display attachments in a single post yourself via the API, for example with `get_posts`.
The only requirement you won't get out of the box is deletion of attachments when the parent post is deleted, as images can be used in other posts so that could potentially break things. If that's not a concern, you can delete attachments on post delete with a bit of code hooked to deletion:
function delete_post_children($post_id) {
global $wpdb;
$ids = $wpdb->get_col("SELECT ID FROM {$wpdb->posts} WHERE post_parent = $post_id AND post_type = 'attachment'");
foreach ( $ids as $id )
wp_delete_attachment($id);
}
add_action('delete_post', 'delete_post_children');

Programatically re-order images in the ACF gallery add-on. Orderby Title, ID, etc
I have a gallery field using the advanced custom fields gallery addon.
This is how I am outputting my gallery fields/images in my theme...
<?php
$images = get_field('gallery');
if( $images ): ?>
<div id="gallery-1">
<?php foreach( $images as $image ): ?>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
<?php endforeach; ?>
</div>
<?php endif; ?>
And this is the only way in the documentation I can see how to implement it.
Does anyone now who how I can order the images by title, id or anything when they are outputted in the loop?
Many Thanks | You can use Php's `usort()` function with a callback. For example, if you want to sort images by ID, you could try something like this (stealing the filter that @Milo used in their answer):
<?php
function sort_callback($a,$b)
{
if ($a['id'] == $b['id']) {
return 0;
}
return ($a['id'] < $b['id']) ? -1 : 1;
}
function my_acf_load_field( $field ){
usort( $field, 'sort_callback');
return $field;
}
add_filter( 'acf_load_field-gallery', 'my_acf_load_field' );
You can adjust the `sort_callback` function to sort by whichever value in the $image array that you'd like. | stackexchange-wordpress | {

post_content with Contact Form 7

What is the best method to close off the backend?

I could restrict logins to a given IP address, but I don't want to keep up with a list of IPs. I'd prefer to use the security my VPN already offers.

WordPress templating system for custom plugins
I'm creating a custom plugin which needs to display HTML with dynamically updated values.
To illustrate, here's what I want to achieve:
<h1><?php print $title; ?></h1>
<h3><?php print $subtitle; ?></h3>
<div class="description"><?php print $content; ?></div>
How can I define a template, pass some variables and get output in return from my custom plugin? I do not want to embed everything as a variable name as it's messy; going back between PHP and HTML in a middle of a function doesn't seem any cleaner either.
What is WP way of doing this?
Thanks! | The various styles of mixing and matching HTML and PHP has always been a bear. Circumstances sometimes dictate the method you use, but many developers prefer one style or another and WordPress tends to use the style in your example.
Another option, which is a bit cleaner in my opinion is to make use of the heredoc syntax in PHP which allows for simple variable substitution. <
$Output = <<< EOF
<h1>$title</h1>
<h3>$subtitle</h3>
<div class="description">$content</div>
EOF;
return $Output;
You can't do away with the PHP variables entirely, but you can make it easier to write, read, and maintain. | stackexchange-wordpress | {

If you choose to use `$wpdb` be aware that another plugin (or theme or whatever) can just overwrite your property in the same way you set it. For that reason, it's a bit more "safe" to use something like a constant.

WooCommerce Grid / List view

jQuery( "ul.products" ).addClass( jQuery.cookie( "gridcookie" ) || "list" );

Long running action from plugin
I'm creating a WordPress plugin that will copy posts data to a remote database, I know it will take a while to transfer all the posts.
How should I create copy functionality so it won't timeout? Ideally it would run in background and show some notification on completion. | You could use WordPress' pseudo-cron and `wp_schedule_single_event`.
<?php
// add the action.
add_action('wpse71941_cron', 'wpse71941_long_running');
function wpse71941_long_running($args)
{
// might need to call `set_time_limit` here
set_time_limit(0);
// do long running stuff here
// return normal time limit
if($l = ini_get('max_execution_time'))
set_time_limit($l);
}
// schedule the event for right now
wp_schedule_single_event(
time(),
'wpse71941_cron',
array('args' => 'for', 'callback' => 'function')
);
Not sure if you need to mess with time limit. WP does call `ignore_user_abort` at the top of the cron script. | stackexchange-wordpress | {

How to use WordPress HTTP API to download file from remote location
So this PHP code works for me:
$ch = curl_init( TCS_CPDF_REMOTE_ZIP );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
$data = curl_exec( $ch );
curl_close( $ch );
file_put_contents( TCS_CPDF_LOCAL_ZIP, $data );
but when trying to use the WordPress HTTP API:
$the_body = wp_remote_retrieve_body( wp_remote_get( TCS_CPDF_REMOTE_ZIP ) );
file_put_contents( TCS_CPDF_LOCAL_ZIP, $the_body );
I end up getting a 0KB file, so the above WordPress version is not working.
So how do you download a file from a remote location using the WordPress API? | Check out `download_url()` \- it's only loaded in the admin, so you'll have to include it (or write your own) if needed on the front-end.
From `download_url()` you can use:
$response = wp_remote_get(
TCS_CPDF_REMOTE_ZIP,
array(
'timeout' => 300,
'stream' => true,
'filename' => TCS_CPDF_LOCAL_ZIP

What's the best way to manage a lot of 301 redirects in WordPress?
Currently my site has a lot of 301 redirects we are managing in our .htaccess file (several hundreds 301 redirects); however, I am wondering would it be better and more optimal I use a plugin such as Redirection to accomplish this? | This is not really a clear question, and plugin suggestions are usually closed, as per the FAQ <
It all depends on what kind of work you want to do: either edit .htaccess or work with a plugin GUI.

Layer post title on top of image Wordpress featured thumbnail image
I'm currently trying to layer a post title on top of the posts featured image but all I see at the moment is " **);">** " instead of the image.
The code I'm using is as follows:
<div style="width:609px;height:364px;background-image:url(<?php the_post_thumbnail(); ?>);"><h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2></div>

article h2 a{
background-color:#bf0c08;
color:#fff;
width:auto;
font-size:30px;
text-decoration:none;
padding:8px;
max-width:479px;
line-height:60px;}
Any idea where I'm going wrong? Also a solution would be awesome :)
You can see this on www.ridermagazine.co.uk | `the_post_thumbnail()` does not return the path of your image. Instead, it returns the complete HTML markup for that image.
You can use this instead:
`$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ) ); echo $image[0];`
If you want a specific size you can pass an additional parameter:
`$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' ); echo $image[0];`
You can either use a keyword for the size (`thumbnail`, `medium`, `large` or `full`), a size you defined with `add_image_size`, or pass an array with your desired size like so: `array( 100, 200 )` | stackexchange-wordpress | {

Wordpress Custom Menu Widget Style
I am wondering if anyone knows the best method for splitting 1 custom menu widget (located in my sites footer) in to 2 columns. There are a total of 8 links, so I would like it to be split in to 2 columns of 4 links. Not sure if there is a function for this or is there some CSS to achieve this? The HTML markup from the widget looks like:
<ul>
<li id="menu-item-133" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-6 current_page_item menu-item-133">
<a href="#">Link</a>
</li>
</ul>
repeat that structure 7 more times for the line items code. | Purely with CSS you could set a width for menu items, float them and then set the UL to twice that:
footer ul {
width: 200px;
}
footer .menu-item {
float: left;
width: 100px
}
(I don't know what elements you are using to designate your footer, you'll need to update that to match your structure.) | stackexchange-wordpress | {

Replacing the WP.me URL shortener with Bit.ly

Why is the media upload button not in the main toolbar & can it be placed there instead?
Is there a good reason why the wp media upload button is not placed within the main edit toolbar, and can we put it there instead of floating above?? | There is an action `'media_buttons'` where these buttons are inserted. Some plugins are using that action to add more buttons, dropdown lists or links. If they had to use the TinyMCE toolbar, they had less room and more restrictions regarding style and JavaScript access.
In short: the current placement is better for plugins.
Moving the default button to the toolbar would probably break some core scripts that depend on that position in the DOM. Maybe you can move it around after `onload`. | stackexchange-wordpress | {

Extract a link in the_content()
I'm trying to improve a bookmarks manager/theme I've built (<
Right now, each post is simply a link:
`<a href=" Tumblr</a>.` ie: that one single link is the entire content of `the_content()`.
Easy enough and works great. Next, I want to be able to get a screenshot of the site via WordPress.com's mShots.
Problem is, I can't seem to extract that link from `the_content()` and feed it into the `<img src="">`.
If that wasn't clear, here's what I'm trying to do:
<img src=" />
I've tried severalvariations on this:
$content = get_the_content();
$link = preg_match_all('#\bhttps?://[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/))#', $content, $match);
But I can't achieve the basic task of extracting that link from `the_content()`. At the moment, I simply get a formatted link output. I can't find a way to grab the url instead of grabbing the whole link.
Thanks for any suggestions. | You're just looking in the wrong place:
php > $txt = '<a href=" Tumblr</a>';
php > $matches = array();

Get a path to a different plugin
To get a the path to a plugin you can use `plugin_dir_path(__FILE__)` \- but this obviously has to be called from within the plug-in.
How can you _reliably_ get the path to plugin B (`pluginb/pluginb.php`) from within plug-in A?
**Edit:** Its assumed you know the slug of the plug-in you're after (actually you can get them from `get_plugins()`). But I would like it to work generally. | My best guess would be:
if ( ! is_file( $dir = WPMU_PLUGIN_DIR . '/pluginb/pluginb.php' ) ) {
if ( ! is_file( $dir = WP_PLUGIN_DIR . '/pluginb/pluginb.php' ) )
$dir = null;
}
return $dir;
However, the danger here is still the assumption of the plugin's "basename" - a well written plugin will still function even when its directory and/or main file has been renamed (for whatever reason).
Which goes back to my original comment - depending on _which_ third-party plugin this is referring to, many authors define their own methods/constants to hold the plugin path - it would make sense to check for their existence & use these instead (if available). | stackexchange-wordpress | {

The_excerpt() doesn't parse <!--more--> - how to change that?
I'm using `the_excerpt();` in blog.php file (post listing page) and it doesn't recognize `<!--more-->` if "Excerpt" field is empty and it grabs the beginning of the content as excerpt.
This issue is described here: < but I don't know why did WordPress disable `<!--more-->` for the excerpt (if excerpt field is empty and content is used as excerpt)?
Can i enable that back? | I do not know why the WordPress powers that be decided to do it the way they did but they don't consider the part before the `<--more-->` to be the same as the excerpt. Whether that makes sense or not is probably an irresolvable matter of perspective. I'd accept it and make do. The distinction actually adds flexibility to your content management so long as you are aware of what is happening. If you want to use the `<--more-->` just do this...
if ( !empty( $post->post_excerpt ) ) the_excerpt();
else the_content();
The code that parses the `<--more-->` is hard-coded into `get_the_content` so it isn't just a matter of removing/adding a filter, though certainly you could juggle filters, or create one, to make this work.

Basics of changing plugin output
There's a Mailchimp plugin I would like to alter it's output in order to match my needs. For example:
1. Order in which fields are loaded are not correct
2. Positioning of the plugin's response messages is not correct.
I have already tried modifying everything using only CSS but I really need to modify the HTML of this plugin.
Is there a way to do this without hacking the plugin itself?
Thanks a lot! | Take a look at WordPress hooks from the Plugin API. There are actions and filters to be used by plugin authors so that other developers could alter the content without changing the core code. However, if they are not used properly (or missing), the only two options are CSS changes (wherever possible, because stylesheets could override the UI at some cases) and the WordPress API hooks (so that you could manage the content globally from WordPress and rearrange order from calling different functions). Custom requirements usually expect flexible plugins with hooks and therefore the lack of them doesn't give you any other clean options. | stackexchange-wordpress | {

How can I reduce the amount of files loaded/included per plugin?
I have a Wordpress site that uses several plugins, namely 8. Most of these plugins include a lot of their own JS and CSS files, some even include so much as 3 separate CSS files. One can imagine that this does a number on the amount of HTTP requests and thus the load time.
Many of these plugins also only get used on certain pages, yet the JS or CSS is still loaded on pages where they are not used.
All of theses files are included automatically in the through WP_head();. Is there a way I can manually include these files and then load them conditionally? Preferably without having to adjust the plugin code itself?
Are there other common practices regarding the many files included by a bigger number of plugins? | Previous versions of WordPress didn't really provide a good means to conditionally enqueue stylesheets and JavaScript within a plugin (i.e. only when needed). So most plugin authors enqueued both on every WordPress init/load, even if the plugin wasn't being used on a given page.
Current versions of WordPress allow for enqueuing later in the flow so you you can, for example, enqueue on your shortcode init/parse.
So you really have only a few options here:
* Use Minify to reduce the file size and in some cases combine files to reduce the number of requests, file I/O, and bandwidth. (Already suggested by @m4t1t0)
* Directly modify the plugins to prevent the enqueue if the plugin is not actually used on a given page.
* Open a support ticket for the appropriate plugin and request the author to update the plugin.

Conditional for a Single Post That Belongs to a Category?
I have categories like `gaming` and `movies` on my website and when a user visits any of these categories the content in the sidebar is displayed depending on the category they are in. So gaming content for the gaming category, movie related content for movies.
When a user selects a post in either of these categories, I have it defaulting to the sidebar that displays on the home page since I don't know how to keep the sidebar displaying the same content that is on the category pages.
The closest I could get would be something like `<?php if ( is_single() ) : ?>`. How would I add `is_category( 'gaming' )` so it can target a `single page` (single.php) that belongs to the category `gaming?` | You can combine conditions:
if ( ! empty ( $GLOBALS['post'] )
&& is_single()
&& in_category( 'gaming', $GLOBALS['post'] )
)
{
// do something
