$wpdb->update Issue

array('%d')

This gives me a white screen. As far as I can tell I have the format correct according the the codex but it is giving me fits. I am sure that it is something simple but if someone would point it out to me I would greatly appreciate it. | array(
'id'=> $result=>id

How should I troubleshoot a database serialization issue with a WordPress migration
I'm migrating a WordPress site from one server to another, and the entire migration seems fine, except the sidebars aren't moving over properly. The obvious thing that comes to mind is a serialization issue with the MySQL migration, but I'm not making any changes to the database because the domain name isn't changing (or even the server paths for that matter). I'm literally just moving it from one box to another. | Rather than mess around trying to find the serialised data that got messed up, just use a tool to migrate environments and avoid messing up serialised data. WP Migrate DB is a good one that handles serialised data properly. The free version does a great job, as long as you don't have a huge database. The Pro version is the duck's nuts, well worth the money. | stackexchange-wordpress | {

Display Images from Array with wp_get_attachment_image()
I'd like the client to be able to type any image ID (number) from any gallery / attachment and then displaying it with wp_get_attachment_image().
Here is my code:
if ( $images ) {
foreach ( $images as $image ) {
echo '<li>';
echo wp_get_attachment_image( $images, 'thumbnail' ); // notice this part
echo '</li>';
}
When I do print_r $images, I get this array: Array ( [0] => 318 [1] => 304 [2] => 301 [3] => 299 [4] => 297 )
and it works if I hardcoding the array, like
echo wp_get_attachment_image( 304, 'thumbnail' );,
but of course I'd like it to appear dynamically.
How to do that? Thanks in advance. | check your code
pass `$image` in `wp_get_attachment_image` not whole array `$images`.
> Be careful when pass parameters
if ( $images ) {
foreach ( $images as $image ) {
echo '<li>';
echo wp_get_attachment_image( $image, 'thumbnail' ); // notice this part

Set start page depending on screen width
I'm building a responsive theme and would like to have different start pages depending on screen width.
In this case, the start page is set in WP admin and contains an image map built on a cunstom page template. On mobilde devices this image map doesn't work so well, so I'd like set one of the other pages as start page.
I guess I can merge front-template with standard-template and somehow achieve this with media queries, but would prefer a javascrip/jQuery solution.
Thanks | It's pretty hard for PHP to know your screen width. It's more of a job for jQuery. But your approach seems kind of backward. If the site is supposed to be responsive -- why are you trying to deliver _different_ pages to your visitors based on screen width?
It would seem you should handle varying content via media queries.
So if you have 5 pieces of content... let's say
1. Header A - intended for desktop
2. Header B - intended for mobile
3. Content - same for all
4. Footer A - intended for desktop
5. Footer B - intended for mobile
You would **hide** the mobile (B) components when screen width is greater than X, and **show** the desktop (A) components.
Conversely, when screen width is less than X, you would do the opposite: **showing** mobile components (B) and **hiding** desktop components (A).

Import JSON feed to Wordpress
We have received a URL which is a JSON file apparently:
I am completely clueless when it comes to JSON and Wordpress.
Anybody know where to start?
We will need to create individual posts from this JSON file I presume.. | 1. json_decode the JSON into an array.

2. Loop into the data

// insert more logic here
}
}
3. Create a post programmatically by using wp_insert_post.
// Create post object
$my_post = array(
'post_title' => $title,
'post_content' => 'This is my content',
'post_status' => 'publish',
'post_author' => 1,
'post_category' => array(8,39)
);
// Insert the post into the database and return the new post ID
$post_id = wp_insert_post( $my_post, true );
if ( is_wp_error( $post_id ) ) {
// error handling....

count number of all comments by a user on different (non-repeated) posts
I thank you in advance for your help. I am using Wordpress for about 2 years, but always avoiding SQL inside my scripts and looking for built-in functions to perform my goals.
To count the comments submitted by a specific user with `$user->ID` as id, I didn't find a built-in way, so I am using:
global $wpdb;
$count = $wpdb->get_var(
'SELECT COUNT( comment_id ) FROM '. $wpdb->comments .'
WHERE user_id = '.$user->ID.'
AND comment_approved = "1"
AND comment_type NOT IN ("pingback", "trackback" )'
);
Actually my goal is to count number of all comments by a user on different posts. In other words, if a user commented 2 or more times on the same post, then only increment the `$count` variable by one .
Your help is appreciated. | If you want to count the number of posts the user commented on, you can try:

$sql = 'SELECT COUNT( comment_ID ) FROM ' . $wpdb->comments . '

AND comment_type NOT IN ("pingback", "trackback" )

Displaying a custom field in Category Archives
I am using WordPress 3.5.1 / Twenty Twelve Theme. I would like to display a custom field in my Category Archives. I have the following custom field working in my single.php , it displays a custom url / title
<a href=" echo get_post_meta($post->ID, "user_submit_url", true); ?>" target="_blank"> <h1 class="entry-title"><?php the_title(); ?> </a>
I would like to put the following code underneath the "entry-title" in Category Archives. I am confused of were to put the following php code, either in category.php or archive.php? Since I need to put this code inside the loop, I want the code to register on every post just like it registers in the single.php in the example I provided above. Something like the following, I presume?
get_post_meta($post->ID, "user_submit_url", true);
Let me know if I need to clarify anything. | If your Loop is constructed correctly `$post` will be set for each post in the loop in turn. You could also consider using `get_the_ID`.
`get_post_meta($post->ID, "user_submit_url", true);` by itself won't do much. You will have to format and `echo` the information but that should retrieve your post meta data.
For example, to generate a link (assuming your meta value is an URL and that you've save a string and not an array):
$meta = get_post_meta($post->ID,'user_submit_url',true);
echo '<a class="meta" href="'.$meta.'" target="_blank">'.$meta.'</a>';
If your theme has a `category.php` and you want this only on category archives put that code in `category.php`. `archive.php` is used by all archives that do not have a specialized template-- tag and author archives, for example.

Reorder plugin items in the admin menu
Is it possible to reorder plugin menu items and custom admin items in the Admin menu without modifying the position in the plugin itself?
I've tried using the method described here "Changing the Menu Order", but when you add a page link like `admin.php?page=pluginname`, it doesn't do anything. Guessing because it can't overwrite the position defined within the plugin.
The Admin Menu Editor plugin works alright, but needing a plugin-less method to handle it to satisfy the higher-powers. :/
Anyone know of a way to get at this? Any help would be hugely appreciated! | Try taking just the name from the page admin link and see if it works. Something like this:

'edit.php', // Posts
'pluginname2', // Take the name from the page menu admin.php?page=pluginname2

'edit.php?post_type=page', // Pages

How many databases do I need?
I have been asked to build another site for someone else. Eventually, I will turn it over to them.
I will develop it locally, then take it live, then turn over full control. In the meantime I need a database for WP to interface with. Do I hook the new site into my existing database that I already have for my personal site or is it one database per website?
I would hate to have export my database along with someone else's. | Multiple installs can share a single database, as long as each install has a unique table prefix defined in `wp-config.php` before going through the install process:
/**
* WordPress Database Table prefix.
*
* You can have multiple installations in one database if you give each a unique
* prefix. Only numbers, letters, and underscores please!
*/
$table_prefix = 'client_1_';
I personally find it easier to just create a new database for each install, as my host allows an unlimited number of databases. I do still however make the table prefix unique for every install, as it could possibly protect against SQL injection attacks if a client installs a bad plugin with insecure code. | stackexchange-wordpress | {

Update post date of page when Visitor access that page?
How to update post date of page to real time when Visitor access that page?
Example: I write a post on May 28, 2013. And now, when I visit that post, it will change may 28 to June 8.
How to do this? | You can hook into the action `the_post` (you get the post as parameter here) and run `wp_update_post()`. Make sure to clean up the _date_ properties and not to run on the admin side or when a post is called in a widget:
is_admin() or add_action( 'the_post', function( $post ) {
if ( ! is_singular() or ! is_main_query() )
return;
$post->post_date = current_time( 'mysql' );
$post->post_date_gmt = '';

Where does wordpress store emails user enters when writing comments?
I'd like to do some kind of newsletter.
My idea is to get emails users entered when they were commenting my blog and send daily email to them all.
Where does wordpress keep that emails?
Is there any recommendation for doing some kind of newsletter/subscription?
Which plugins do you recommend? | The email address associated with comments is kept in the `$wpdb->comments` table. Strictly speaking, that is the answer to the primary question.
I'd be cautious culling email from comments as posting a comment is not clearly giving permission for you to send email.
> Is there any recommendation for doing some kind of newsletter/subscription?
Use a third party service like MailChimp or Constant Contact (not affiliated with either). Many hosts do not allow mass email through their mail servers. (Check your terms of service.) And, while I am not a lawyer, it seems to me that complying with the legal requirements for sending mass email can be tricky-- especially since I am not a lawyer. A decent service will deal with most of that for you.
Plugin recommendations are off-topic but you can search the plugin directory. There are a lot of plugins related to this subject, including plugins that interface with the services mentioned, and others not mentioned. | stackexchange-wordpress | {

Add background image/layout for single page?

<body <?php if(is_page(123)) echo 'class="custombg"' ?>>

Underscores in custom fields
While trying to perform a WP_Query using meta_query(), I had some trouble because the custom fields created by a plugin had `_` in the beginning of its name.
Although I noticed it was stored this way in the database, I had no idea why it was there and thought I had to reference it without the underscore (for the record, that is wrong).
Why do some custom fields start with underscores and others don't? What are the underscores used for? Are they mandatory in some circumstances? | Custom field names are arbitrary. The underscore hides it from the _Custom Fields_ metabox on the post editing page. When referencing these custom fields in `meta_query()` or other functions, the underscore has to be used.

What is WordPress file encoding?
I noticed that WordPress files use UNIX end-of-line and UTF-8 without BOM. Is this a standard that should be used? Is there anything else to pay attention to?
I noticed that Filezilla fails to transfer Macintosh end-of-line files properly to Windows or Linux servers. New line endings are missing. And sometimes they are doubled with different configuration. I'd like to avoid that if possible. | UNIX line endings (`\n`) and UTF-8 are just common code standards. As far as I can see, they are not even mentioned in the Coding Standards. Most (all?) core PHP files are just plain US-ASCII. Try to follow that path to keep your files as compatible as possible.
If you use UTF-8, add a line at the start of a PHP file with an _Encoding Cookie or file variable:_
<?php # -*- coding: utf-8 -*-
Many editors (Emacs, Vim, Sublime, Scite) will use that to set the proper encoding automatically.

Set a cookie only in single posts
I'm trying to set a cookie when a user is on a single post. I'm keeping track of how many single posts he has read this month. I have two problems:
I have a custom template and added the following code to my functions.php

if (is_single()){
$postNumber = $wp_query->post->ID;
setcookie($postNumber,'visited',time()+60*60*24*31);
}
}
add_action('init', 'articlesVisited');
First. The code inside is_single() is never reached when I visit a single post on my site. If I put an -else- block after it, it executes that.
Second, the $wp_query->post->ID does not give me the ID of the post. I think that has something to do with global variables...
Does anyone has experience with this? | `init` is too early (it happens before the main query), use the action `template_redirect` instead.
And for the ID use `get_the_ID()`.

if admin option the category is an id
display its id
if in admin option category is a name
display its name
Thanks | You can't use the category name to search for categories. You can use the slug. Be aware of the difference. A slug is normalized to lower case with spaces replaced by dashes. The slug for "Foo A" would be "foo-a". Using "Foo A" will not work.

What is content.php file that is needed for Jetpack infinite scroll plugin?

Get file headers in custom file
in my one of my plugins i have modules (kind of like plugins in a plugin), is there a function like `get_plugin_data()` or `wp_get_theme()` that will allow me to get the header section of a custom file (by passing the path as a parameter)?
By heading section i mean
/*
Plugin Name: Name Of The Plugin
Plugin URI:
Description: A brief description of the Plugin.
Version: The Plugin's Version Number, e.g.: 1.0
Author: Name Of The Plugin Author
Author URI:
License: A "Slug" license name e.g. GPL2
*/
Thanks to @toscho the correct solution was
$default_headers = array(
'Module Name' => 'Module Name',
'Test Header' => 'Test Header',
);
$file_data = get_file_data(dirname(__file__).'/some-file.php', $default_headers);
print_r($file_data); | Use `get_file_data( $file, $headers )`:
$file_data = get_file_data( __FILE__, array ( 'Plugin Name' ) );
echo "the name is " . $file_data[0];
Make sure the first parameter points to an existing file.
It will find all lines that are formatted like regular plugins headers or the headers of a `style.css`.

Export data as CSV in back end with proper HTTP headers
I wrote a plugin that displays all products in a woocommerce store in admin settings option, now I want to add a link to download the products as CSV file.
The problem is, when I click the link I get a permission error saying I don't have permission to view this page.

function extra_tablenav($which) {
if ($which == "top") {
echo '<h3 style="display:inline">'

. '</h3>' .
' ' .
'<a href="' . admin_url('admin.php?page=download_csv.php') . '">' . __('Export to CSV') . '</a>';
}
}
How can I fix those permissions? | Do not point the URL to `admin.php`, use `admin-post.php` instead:
'<a href="' . admin_url( 'admin-post.php?action=print.csv' ) . '">'
In your plugin register a callback for that action:
add_action( 'admin_post_print.csv', 'print_csv' );
function print_csv()
{
if ( ! current_user_can( 'manage_options' ) )
return;
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=example.csv');
header('Pragma: no-cache');
// output the CSV data
}
If you want to make the data available for anonymous users (not logged in), then register the callback again with:
add_action( 'admin_post_nopriv_print.csv', 'print_csv' );

How to save a viewer specific option

* when switched to green, background shall stay green while exploring the blog
Is there a standard interface in Wordpress for saving a global PHP variable $bgcolor to the viewer and read it from him anytime he browses to another blog page.
(I'd like to avoid setting a cookie "by hand") | > Is there a standard interface in Wordpress for saving a global PHP variable $bgcolor to the user and read it from him anytime he browses to another blog page.
There is nothing that will automagically do it for you but it sounds like you just need to save a little bit of user meta, and of course retrieve it.
Since you asked about saving the variable, I am going to assume that the custom sidebar widget that switches the background color already works. Just add code, based on the two Codex entries above, that checks the user meta and saves changes.
If you post your code, I may be able to give a more elaborate answer.
If you are talking about generic visitors, and not WordPress users, setting a cookie is your best choice. There are no built in generic "cookie setter" functions that I am aware of. WordPress itself uses PHP's `setcookie` in a fair few places, for example in `wp_set_auth_cookie`, and I don't know why that function would need a "helper".

Hope this is not a duplicate, I've been searching on wpse, found nothing related. Thanks in advance. | With markup embedded into the content there is no less tricky way than regex to do it, save perhaps a markup parser like SimpleHTMLDom

Custom shortcode that writes to file
I'm trying to maybe do too much in a shortcode call. Here's the code I have:
//[rand]
function randnumber_func( $atts ){
$digits = 4;
$randnumber = rand(pow(10, $digits-1), pow(10, $digits)-1);
$space = "\r\n";
$myFile = "offer_codes.txt";
$fh = fopen($myFile, 'a+') or die("can't open file");
$stringData = date("F j, Y, g:i a") . " - " . $randnumber;
fwrite($fh, $stringData.$space);
fclose($fh);
return $randnumber;
}
add_shortcode( 'rand', 'randnumber_func' );
I want to create a random 4 digit number and have it printed to the page. I also want to take that random number, append the date to it, and have that written to a text file. It works in PHP, but not when I call it via a shortcode. Is something it Wordpress stripping it out or do I have it written incorrectly for the shortcode function? | Your code works for me on a development server.

List Categories (wp_terms) and count posts
I have a problem (of course) and I'll go straight to the point: I need to list all the custom categories and count the posts for each category eg.
* Category 1 (xx posts)
* Category 2 (yy posts)

plugins_url('',__FILE__) != WP_PLUGIN_URL with sym links
For one of my many sites, `plugins/plugin-name` is a sym link pointing to `universal-install/wp-content/plugins/plugin-name`.
`echo WP_PLUGIN_URL` displays what I expect.
`echo plugins_url();` displays what I expect.
`echo plugins_url('',__FILE__)` displays what I expect followed immediately by the absolute path to the universal plugins directory.
Is there any way I can fix `echo plugins_url('',__FILE__)` to return only the expected result? | When writing a plugin, I define a few constants including the path to the plugin's root folder, and its "name" as used in some admin hooks:

I've found that `plugins_url()` happily takes that constant, which is useful when referencing files from subfolders of the plugin, like so:

Returning Variables back into a template
If I put a function that I want to use in a template I can put it into functions.php
function myfunction(){
echo 'My String';
}
`add_action('myfunction','myfunction');`
and in a template file put:
do_action('myfunction');
This appears to only work if writing something out to the screen. If I wanted to return a variable instead to the page. E.g.
function myfunction(){
return 'My String';
}
$string = do_action('myfunction');
and capture it instead of print it. How would I do it? | There's filters for that.
Example:
add_filter( 'template_filter', 'wpse_102706_filter_callback', 10, 2 );
function wpse_102706_filter_callback( $defaults, $case )
{
$args = wp_parse_args( array(
'some_key' => 'some_modified_value'
), $defaults );
return $args
}
Then in your template just add in the defaults:
apply_filters( 'template_filter', array( 'some_key' => 'default_val' ), 'single' );

Exporting just posts of a specific category
I have found the export tool particularly useful for moving posts from sites to site, and even once wrote an extension for Elgg to export its content into wordpress export format for migration to BuddyPress.
However, I now find I'd like to export just the posts of a single category, so that I can put those posts on a different wordpress install whilst leaving the other posts on the original site. Given the number of posts on the site, I'd rather not have to export everything and manually edit the xml file.
Is there a way I can export posts of just one category into a standard wordpress import/export xml file?
The site being imported to is on the same multisite install, with shared user base, so post and comment attribution should be preserved. | The default exporter will do this. Instead of selecting "All Content", choose "Post" and then a category.

Is it possible to have a Theme with built-in physical page files?
I am creating a theme and was thinking if it would be possible to create pages within my theme folder that would reflect the wordpress url + path.
So for example I could when accessing: <
it would looks for about.php or about.html inside my theme folder?
I have obtained success doing this but handling the `is_404` method and then rendering the page with `get_template_part($pathname)`, however, every page will output the 404 response status which is not viable?
Is there any other way to accomplish that? I wish there was some kind of url aliases I could grant for my theme and could use it.
Thanks in advance | WordPress would allow this (sort of). You would still need to create an About page in the back end, but you can tailor your display for such a page 2 different ways:
1. Page Templates
2. Page template hierarchy \- What this means is there is a certain order of what WordPress is looking for when displaying any page/post. Check out the image here for a more direct understanding.
For pages specifically, the default is page.php, but page-$slug.php has higher priority. So in this case, you could make page-about.php, and alter what is displayed on that page. I would **strongly** suggest keeping the main content within that page, but this is how you add additional items to a page structure, such as sidebars, "Related Items" links, etc. | stackexchange-wordpress | {

How to over-ride a file in a plugin?
I have a third party plugin that I'm using for a photo gallery (NextGen). However, with my black background, the loader gif animation looks pretty bad. I found a better loader gif and replaced the one from the plugin. I already know this is not ideal because the next update of the plugin will overwrite my custom gif.
The gif is located at: `/wp-content/plugins/nextgen-gallery/images/loader.gif`
Is there a clever way to leverage my child theme's `functions.php` file to tell this plugin to use a different URL for the gif?
As far as using my child theme's CSS to override, that would be easiest if it was a viable option. However, the loader's URL is not coming from the plugin's CSS file. | Use a rewrite rule in your .htaccess:

Wordpress Settings API settings not saving for some users

Some users are saying that settings aren't saving.

Though ike I said, it's working just fine for me that's why I'm confused...
Here's the pastebin of my options.php: < | Here are few remarks after skimming through your code:
* you are using options name like `id`, `title` and `global`. You should use a prefix on these names, like `vegas_`, to avoid possible problems with other stuff using these option names.
* you should let the users know about validation problems (check out the `add_settings_error()` function)
* use `trim()` on your text fields values when you save.
* use `esc_attr()` to escape your HTML attributes.
* develope your plugin with `WP_DEBUG` activated, so you can catch any errors before you ship your plugin.

Getting the current post number / make posts increment

Adding querystring variable breaks admin URLs
I've set up some admin pages using add_sub_menu() and whenever I add an additional querystring variable beyond the "page=" portion of the URL, I get a "Cannot load 'page-slug'." message. When I remove the every variable the page loads correctly. Here is my add menu code:
add_submenu_page(
'plugin-slug',
__( 'Post Types - Add', 'plugin-slug' ),
null,
'manage_options',
'plugin-slug-posttypes-add',
'display_admin_page_posttype_add'
);
If I browse to:
/wp-admin/admin.php?page=plugin-slug-posttypes-add
it works fine. But browsing to:
/wp-admin/admin.php?page=plugin-slug-posttypes-add&post_type=sampletype
returns:
Cannot load content-toolkit-posttypes-add. | You're recieving this error because WordPress notices the `post_type` query argument and that `sampletype` is a valid registered post type, and thinks you're on an edit page. Try using a different query arg then `post_type`.
Note that `admin.php?page=plugin-slug-posttypes-add&post_type=thisisnotaposttype` and `admin.php?page=plugin-slug-posttypes-add&foo=bar` will both work fine. | stackexchange-wordpress | {

Animate.CSS with a child theme
I am trying to implement animate.css with my Twenty Twelve child theme. I read this post about trying to implement it (option 1), but it is not working. The only thing I am doing differently is that I have a child theme. Any thoughts? Thanks a lot!
**Edit:** Milo, you're first answer did not work. This is my code in my child theme's function.php:
function paukai_2011_styles() {
wp_register_style( 'animate-css',
get_stylesheet_directory_uri() . '
array(),
'20120725',
'screen' );
wp_enqueue_style( 'animate-css' );
}
And here is my html:
<p class="animated wobble">This is dummy text</p>
No luck unfortunately. | The example in the page you linked uses `get_template_directory_uri()`, which will only give you the parent theme URI. If you want to target something in a child theme, you have to swap that for `get_stylesheet_directory_uri()`, which will give you the child theme URI, in the event a child theme is being used. | stackexchange-wordpress | {

meta_value and meta_key filtering returning no posts
this might sound like a very stupid question, and I am almost ashamed to put it here... however, after using the code straight from wp codex, and trying a couple of other variations from googling around, i simply have NO IDEA why this is not working!
here's what i am using for the wp query on the index.php
$args = array(
'post_type' => array('photographs', 'published_works'),
'meta_key' => 'place',
'meta_value' => 'usa',
'posts_per_page' => '-1'
);
i set up a custom taxonomy called 'place', and 'usa' is one of the terms. i can get to the archive page easily, but if i want to filter it out in the index page, it simply shows no posts at all.
so, i am assuming that the mistake is probably elsewhere, since the code above is taken straight from codex. any ideas of what i might be doing wrong???
much appreciated! | Taxonomies and meta data (Custom Fields) are two different things. If you want to filter on a taxonomy term, you want a `tax_query`, not a meta query. | stackexchange-wordpress | {

Cron Job variable not accessible
I am currently running a cron job on my cPanel to update a variable containing exchange rates, how can I make this variable available to functions and pages in my wordpress site?
**My command in cPanel for cron job running every minute:**
php -q /home/username/public_html/cronjob.php
**cronjob.php**
<?php
require('wp-blog-header.php');
$exchangeRates = getExchangeRates();
function getExchangeRates(){
// etc etc
} | First of all, it's best not to include `wp-blog-header.php`. Instead, set the cron job to your homepage URL with a `?mycustomcron=true` variable appended (eg: ` Then we will check for the existance of this variable when the page loads:
function wpse_103127_check_cron() {
if ( isset( $_GET['mycustomcron'] ) ) {
// things to do on cron here
exit; // no need to load the page on cron
}
}
add_action( 'template_redirect', 'wpse_103127_check_cron' );
As for saving the data for later access in WordPress, you can save the data to the `wp_options` table:
$exchange_rates = getExchangeRates();
update_option( 'exchange_rates', $exchange_rates );
And then access it later:
$exchange_rates = get_option( 'exchange_rates' );

Adding Menu Items in Custom Post Types

Cannot upload featured image to a custom post type
For some reason I am not able to upload images OR set the Featured Image on a custom post type in my custom wordpress theme.
I have added theme support of post-thumbnails to my functions.php file and my custom post type supports it. The link to add the featured image works and it allows me to start uploading the file. But before the file can complete it gives me the error message "An error occurred in the upload. Please try again later". If I visit the media library directly, the file is there, but it shows an error in the custom post page.
Also, when I open the media library from the custom post page it shows as empty.

search page different results

'before' => '<div class="page-links">' . __( 'Pages:', 'bsq' ),
'after' => '</div>',
) );
?>
</div><!-- .entry-content -->
<?php endif; ?> | is_search() is going to return TRUE on every search you perform, so that won't do what you need if I understand correctly. You'll have to use a post_type conditional tag. But it shouldn't be too difficult with something like
if (is_search()) {
if (get_post_type() == 'type_1') {
//Do the right styling
} else if (get_post_type() == 'type_2') {
//Do different styling
}//endif

limit post by a taxonomy in the admin

Kat | Within the javascript file the developer calls a method when the page loads.
jQuery(window).load(po_selectiveLoad);
This methods calls another method.
function po_selectiveLoad() {
po_load_popover();
}
If you replace it with this
function po_selectiveLoad() {
var urlString = new String(window.location.href);
if (!urlString.match(/\/cart\//)) {
po_load_popover();
}
}
Of course this is not good because you will need to modify the plugin files.
I am not sure if the developer has provided the option of preventing a pop up based on a phrase or word contained within the url, i installed the plugin and did not see an option.

IOS home screen icons: where put and what size?

div having different appearances in different themes
I have a shortcode in a plugin that is supposed to display a div. The div can be styled in the settings.
The problem is: the div has different appearance in different themes. This obvious is caused by other themes modifying the styles in a generic way that I am not specifically handling.
What is the _optimal_ solution such that its appearance remains same through out themes. One obvious one is to override **ALL** possible css properties in the my div related styles. Is there a better way to do that? | You need to be specific when defining your CSS styles so that a theme will not overwrite your intended style.
When outputting your markup, perhaps you should even consider wrapping your div element within another div element and assuming this is the only markup on the page, you can specify them both with an #ID selector as opposed to a class selector, then in your CSS styling:
div#myPlugin div#innerWrap {
background: black
/* etc */
}
...and so on.
That is going to be pretty hard to overwrite as you are being far more specific than what a theme could possibly ever be without the theme knowing the exact div ID names ahead of time, **_which they wont_**.
You could also inject your styles inline which will take top precedence over all other defined styles,
<div id="myPlugin">
<div id="innerWrap" style="background:black">
content
</div>
</div>
