What is a reasonable get_num_queries() result?
What is a reasonable number of results I should expect with get_num_queries()?

Finding posts containing matching array elements in a meta field usign WP_Query
I have a metafield, that contains a series of options and writes the results to an array in a single meta field:
array([0]=>'First',
[1]=>'Second',
[2]=>'Third',
);
I find posts that contain any of the array elements, and display them using `WP_Query`
$search = new WP_Query('meta_key=mykey&meta_value=second');

$args['meta_value'] = "%|".$value."|%";

But no darts. | I believe you have to use meta compare LIKE. If you do a regular meta query, the resulting SQL will be meta_value = your_value, which is never going to find anything because it's trying to match the entire contents of the field. | stackexchange-wordpress | {

Cannot get redirect working

Data sanitization for user registration and user login
What kinds of data sanitization I have to do if I make a front end login and registration system for wordpress users?
1. For login function `wp_signon()` should I escape the data for possible sql injection or wordpress will automatically do it for me?
2. For registration I have found two function so far `wp_insert_user()` and `wp_create_user()` and for updating user `wp_update_user()`

Do i need to do the password hashing?

Creating custom tags

i've a question about using tags to simplify my HTML. For example if i want to ad a block of content lets say a contact form. I don't want to ad all the time my html code can i use a tag something like:
`#contact_form` and that this tag output a contactform for me.
If this possible can someone please give me a link to tutorial or gives a example.

functions.php conditional tag only for custom post type
I'm using gpp slideshow, which overwrites wordpress's default gallery display. I only want to use it on my custom post type, "listings" - how would I reference it to only replace wordpress's default gallery on the "listings' page?

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

remove_shortcode('gallery', 'gallery_shortcode');

}
}

if (is_single() && is_post_type('post_type'){
and that returns an error.

Use wp_enqueue_style based on user option in widget
I currently developing wordpress widget for my website. This widget will pull user latest post in my website and show in their blog.
In the widget there is option for user to use their css or my css for the widget
I use this code in my widget and its work perfectly but this code will always load the css.
add_action( 'widgets_init', 'load_my_widgets' );
function load_my_widgets() {
register_widget( 'My_Widget' );
wp_register_style( 'my_widget_css', ' );
wp_enqueue_style( 'my_widget_css' );
}
The problem is how can I enable the CSS based on the user option? I try something like this but its not working
function widget( $args, $instance ) {
$own_css = isset( $instance['own_css'] ) ? true : false;
if ( ! $own_css ) {
wp_enqueue_style( 'my_widget_css' );
}
} | This is sort of sloppy as the style will still be enqueued regardless.
In the code to display your widget, change the CSS selectors based on whether or not the user selected own style:
<?php
$prefix = $instance['own_style'] ? 'ownstyle_' : 'pluginstyle_';
//then....
?>
<div id="<?php echo $prefix; ?>selector"> ...</div> etc
A user would be able to use both a widget with custom style and one with default style this way. Enqueue your style separately in its own function.

function wpse26241_enqueue()

Migrating from other CMS to WP - losing SEO juice?

What is a reasonable memory limit for Wordpress
Although the accounts on my server generally have a lower memory limit, I've configured my Wordpress user accounts with a memory limit of 32Mb using the php.ini file and `memory_limit = 32M`
Unfortunately I've found that I'm still getting the odd memory error, even on small tests blogs. I've had to increase the limit to 64Mb which in my mind seems a little high for normal usage.
What should be a reasonable upper memory limit to have on standard Wordpress installs with popular plugins? For your information some of the plugins that I suspect might be causing memory issues are:
* W3 Total Cache
* Role Scoper
* Smush.it | Obviously this question is a little squishy, as YMMV, but I've run several WP sites using W3TC and similar plugins to yours on 32M, and haven't had an issue.
That being said, when are you typically running into issues? Is it on post submission? On gallery operations? Looking for a pattern there could be helpful. Let us know if you find one.
Also remember that a limit is just that, a limit. The majority of the time your site will not be running at the max of 32 or 64M, especially with a caching plugin like W3TC installed and properly configured. PHP may burst to 64, but so long as your server can handle bursts up to that level, then you should feel comfortable with it. Generally, memory limits can be set a little higher than what you'd expect, and so long as you aren't causing your server to thrash then you are fine. Try running `top` or `free -m -s 5` to examine memory usage over time, and see if you're constantly running close to the limit, or if it will continue fine as it is. | stackexchange-wordpress | {

How do I access cPanel features within Wordpress?
Is there a plugin that can access cPanel features from within Wordpress? In particular I'd like to be able to:
* View bandwidth, quota and other server info from the WP Dashboard
* Access my webmail
* Access the file manager to edit files (useful for .htaccess, php.ini and non-WP files)
I know I can just open a new tab and log on to my cPanel account, but it would be great if it could be integrated some how.
If there isn't a plugin to achieve the above, then I suppose an easier way would be for some links to be added to the Dashboard menu (for example webmail and file manager) which would link directly to those sections in cPanel and perhaps open in an iframe.
So, to recap... does a plugin exist to achieve the above (or it easy to make one) or if not, does a plugin exist (or how do I create one) that adds these links to the dashboard. Any ideas from people who use cPanel and WP on a regular basis would be helpful. | I do not believe there are any plugins specifically catered to cPanel, however there are a few plugins which will allow you to add an iFrame to your admin pages.

Plugins in mu-plugins folder are not loaded
I'm trying to load plugins automatically by putting the plugins into `mu-plugins` folder. But if the plugin is put in a folder, it isn't loaded. I tried some popular plugins such as W3 Total Cache, WordPress SEO By Yoast, but all of them are not loaded.
Does WordPress only loads plugins which are just single files in `mu-plugins`? | > Does WordPress only loads plugins which are just single files in mu-plugins?
No, they do not need to be single files but you cannot use plugins in their own subfolders as in the standard `plugins/` folder.
**The main plugin file** (one with the specified plugin header info) **has to be right there in** `mu-plugins/` **.** Other files can be put in a subfolder and referenced from there.

Use [embed] filter in template files

Best Practice for Displaying Categorized Posts on Front Page

Any suggestions greatly appreciated | You can use WP_Query in your template to select groups of posts by type, category, tag, custom taxonomy, meta field, etc., and create additional loops:
<?php
$news = new WP_Query("post_type=mynews&posts_per_page=1");
while($news->have_posts()) : $news->the_post();
the_title();
endwhile;
$events = new WP_Query("cat=2&posts_per_page=3");
while($events->have_posts()) : $events->the_post();
the_title();
endwhile;
// etc..

How can I create custom URL routes?
I have a very peculiar requirement, but hopefully I can explain it without being too confusing. I created a page template where I list some properties I get from an external XML file. So far no problems, and let's say the URL is like this:
Each property has a link that should redirect the user to a "Single Property" page that displays more information about it. I was wondering if there's a way to make the link like this:
Where `123` would be the id of the property. So if I have the URL like `properties/some_id` I want to be able to load a view file (like the `single.php` or `page.php` files), but specific to this URL condition.
Is this possible? | Add this to your theme's functions.php, or put it in a plugin.
add_action( 'init', 'wpse26388_rewrites_init' );
function wpse26388_rewrites_init(){
add_rewrite_rule(
'properties/([0-9]+)/?$',
'index.php?pagename=properties&property_id=$matches[1]',
'top' );
}
add_filter( 'query_vars', 'wpse26388_query_vars' );
function wpse26388_query_vars( $query_vars ){
$query_vars[] = 'property_id';
return $query_vars;
}
This adds a rewrite rule which directs requests to `/properties/` with any combination of numbers following to pagename `properties`, with the query var `property_id` set. Just be sure to visit your permalinks settings page and save to flush rewrite rules, so this new rule will be included.
In your `page-properties.php` template, `get_query_var('property_id')` will return the property id if it was set, if it's not then show the default properties page. | stackexchange-wordpress | {

Review site custom post type structure

* Action
* Comedy

* Tv Show
* Action
* Comedy
* Drama
And of course, if i click on the Tv Shows/Action, i only want to display all of the reviews inside the Tv Shows category which has an Action genre, and only the TV show, not the movies.
What is the easiest solution to do this? | The way that I would approach it is using the tax_query to create a query that looks for both the correct genre and type. For example, to query all Movies that are Drama:
$myquery['tax_query'] = array(
array(
'taxonomy' => 'genre',
'terms' => array('drama'),
'field' => 'slug',
),
array(
'taxonomy' => 'type',
'terms' => array('movie'),
'field' => 'slug',
),
);

Why would a GET variable one one page of a site cause a 404 error when a GET variable works on another page of a site?
For example I have 20 pages on a site. one of them is called bacon another called eggs. on the same site...lets say breakfast.com
I have the permalinks set up properly and have used them successfully on all pages, including Eggs by way of this: www.breakfast.com/eggs?cooked=scrambled. This works 100% as it should.
However, on a different page of Breakfast.com called sausage...this, does not work. www.breakfast.com/sausage?type=spicy
this is causes a 404 error. I don't see why it would as it's the same format. I have verified that the page exists in my pages directory in WP-admin.
If I strip away the GET variable the page works. Google is not helping me. Anyone have a similar experience? | WordPress has a list of reserved terms that you _cannot_ use for taxonomies. From your question, I gather that "cooked" is a taxonomy that applies to eggs and "type" is a taxonomy that applies to sausage. Unfortunately, "type" is a reserved term in WordPress, so it interprets your query string differently than you expect.
The full list of reserved terms is available in the Codex. Just use a different term ... maybe "sausage-type" ... for your taxonomy and you should be in the clear. | stackexchange-wordpress | {

Why is 'is_multisite' returning true when it's a single install?

echo 'IS NOT MULTI'.$_SESSION['root_image_dir'];
}
For some reason, the `echo` statement is triggered every time.
Why is `is_multisite` not working?. | If that's the code you have in your plugin, you're writing it wrong. You have `if(is_multisite)` which is treating the string `is_multisite` as a constant and evalutation to true. Essentially you're writing `if(true) ...`
Remember, `is_multisite()` is a _function_. You need the parenthesis at the end for PHP to actually evaluate the function. Change your code to the following:
if( is_multisite() ) {
$upload_dir = get_upload_dir();
$_SESSION['root_image_dir'] = str_replace('\\','/',$upload_dir['basedir']);
echo 'IS MULTI.'; //<-- this is outputted every time

How to use WordPress authentication on non-WordPress page?

Note that the file must be in the same folder as your theme.

What 'function' will 'update' a post?
I am using a script to import my vbulletin forum posts into wordpress as posts.
One quick issue I ran into is there are numerous forum posts with the same title 'please help me'.
When I go into the post edit screen the permalink will show 'please-help-me-2' for the second one, and 'please-help-me-3' for the third one. That is exactly what I expect.
However, when you go to **view the second one on the front end of the website** , instead of having the -2 appended to the end of the url, it simply says 'please-help-me'.
If I 'update' the post, then the permalink saves properly and the front end link changes like it should.
**What I need:**
Is there a function that I can use to go through the posts database and have it automatically 'update' all the posts so that the permalinks will change properly on the front end?
*we're talking 1.25million posts here, so automation is important.
thanks | There is a function called wp_insert_post that takes a parameter for post ID. If the post ID is an ID that already exists, this function will update the post with the information you pass in the function parameters.

function new_title($title) {

$title['custom_version'] = 'Application has been updated to v'.$title;

} | The issue is that you are mixing up the `$title` variables. `$title` is the parameter passed to the `new_title` function, but then you use it as an array: `$title['custom_version']`. Try this:
add_filter('the_title', 'new_title', 10, 2);
function new_title($title, $id) {
if('custom_version' == get_post_type($id))

I want to list them in my own custom order. How do I do this? | Now that I have a better understanding of the issue, I would recommend using custom fields to sort your posts. You can have a custom field (e.g., "order") and use it to indicate the order of your posts. You then need to use a custom query to order these posts when they are displayed. You can use a custom query like the following:
$args = array(
'meta_key' => 'order',
'orderby' => 'meta_value',
'order' => 'ASC'
);
$custom_query = new WP_Query();
$custom_query->query($args);
if($custom_query->have_posts())
{
while($custom_query->have_posts())
{
$custom_query->the_post();
// Do the loop stuff
}
}
Please see the WP_Query class page for more information about all of the arguments that you can use to create custom queries. | stackexchange-wordpress | {

Is there any way of making post tags (or custom post type tags) pop up as suggestion as in StackExchange sites?

Best way to transfer Wordpress install to root of directory when I'm ready to launch?

Force WordPress to NOT display the manual excerpt

Is there a way to force WordPress to display an automated excerpt (ie, the first 80 words) on one page template only? | You can utilize the `wp_trim_excerpt` filter. In your callback function that filters the the excerpt text, you can test for the presence of a certain template; then, if that template is being used, you can go ahead and alter the excerpt in any way that you see fit.

What does a security risk in a plugin look like?

Two questions:
1. Is it possible for a security hole in one plugin to allow someone access to other sites on the same server?
2. What would a security flaw look like that might give someone access to the .htaccess file a directory or two above?

Why doesn't my page know it's a page (won't return true for is_page())?
I have a page with the slug `blog`. Mysite.com/blog correctly renders from the template file page-blog.php. However, it does not execute footer code from my theme that's conditioned on `is_page('blog')`, nor does it have an "Edit Page" link in the Admin bar.
I also have a custom post type called `blog`, but this page doesn't execute code for `is_post_type_archive('blog')` either. In the admin bar, there is no "Edit Category" link or "Edit [Anything else]".
This is the info the WP Debug plugin gives me when I load the page:
Request:
blog
Query String:
pagename=blog
Matched Rewrite Rule:
(blog)(/[0-9]+)?/?$
Matched Rewrite Query:
pagename=blog&page=
What could be the problem? | The problem was due to a secondary loop in the page—before this loop, the page knows it's a page; but after the loop (and in the footer, where the Admin Bar and my code would be rendered), the page thought it was the last post of the secondary loop.
Neither wp_reset_query() nor wp_reset_postdata() worked; I am guessing this has to do with the fact that I use $wp_query as the name of the secondary loop (so that I could use the loop.php template file to display the posts). Here's the code that worked:
$temp_query = clone $wp_query;
$wp_query = new WP_Query( 'post_type=publication&posts_per_page=5' );

Dynamic page outside Wordpress
I have some data that I'm pulling from an XML source and would like to display it in Wordpress.
One solution would be to take the static markup that my theme generates and spaghetti-code my page with some PHP that grabs the data from the XML and prints it in the page. Easy enough, but now every time I make a change to the theme I have to re-apply it to this page.
Is there a more elegant solution that would allow me to inherit the whole site look n' feel and just append my data to it?
Thanks | I would make a plugin out of the code that you are using to pull the XML. I've done this before for a client that was using a calendaring system that was a set of PHP files. I wrapped the calls to the calendar files in a plugin, and just called what I needed to from there. This preserved the look and feel of the site without extra work there, and used WordPress's native capabilities.
It's fairly easy to take an existing set of code and wrap it as a plugin, and then you can use the methods of that plugin in your theme files. You could for example make a page to house the data, make a page-specific theme file that outputs (or not) the content of that page, and also use the theme file to run the methods for pulling in the XML data via your plugin.

next gen gallery thumbnail problem
Does anyone know why nextgen gallery doesn't support thumbnails with png transparency???
I'm working on this project <
And as you can see the slideshow work the image properly, however the thumbnails have a black background.
I'd really appreciated any kind of help :)! | since the site has a white background, a quick workaround could be to save the pngs as jpeg with white background?
this thread mentions a possible solution:
* wordpress dot org/support/topic/plugin-nextgen-gallery-problems-with-png-transparency-thumbnails?replies=9
this has an unpdated solution:
* wordpress dot org/support/topic/plugin-nextgen-gallery-png-thumbnails-with-transparancy-problem-1?replies=5
and this thread suggests saving as 24bit png's rather than 8bit
* wordpress dot org/support/topic/nextgen-gallery-transparent-images-showing-black-background-with-resize?replies=8#post-1921440
ps cant post all links as dont have enough rep :-(
if an admin can amend i'd be grateful | stackexchange-wordpress | {

Homepage slider not using correct images
I am currently in the process of starting my first blog. Currently, I am stumped. I have a homepage slider that refuses to work with me. The documentation for the theme I am currently using is located here. The problem I'm having is I can't figure out how or what the slider decides to use as an image and then the caption in the slider and how to add more to the slider. I would like it to be a the larger picture 970x360 or something like that with the caption beneath it with 3 or more pages to slide through, not have the description overlayed on it. I've gone into the theme option and messed around to no avail. I'm am lost as to where to go from here. For the visuals on the issues please see my blog. | I was able to solve the problem by hard coding. The documentation was to vague and not properly detailed for me to figure out how to use the settings. Here is the code:

<div id="slider">

wordpress multisite, how to keep user on subdomain throughout registration process?
I am running wp subdomain multisite in combination with domain mapping. This means I can create a new subdomain site xyz.site.com and map the domain name 'xyz.com' to that site.
The problem I have is someone clicks 'register' on the subdomain mapped site 'xyz.com' and they are sent to site.com to register.
This is VERY confusing to many people and I'm getting tired of the complaints.
How do I setup wp multisite, so that if a person wants to register on a subdomain site, that they do not leave that site at any point?
_I use multisite to host multiple client sites, all which have their own domain names. I simply 'map' the domain name to their subdomain site. This means that users who come to one clients site to register, are being sent to the primary site to register, which is just plain wrong and confusing_ | What @petermolnar suggested also redirects your users to the main site if they want to register (I've tested this but feel free to make use of it. It's good practice).
What you need is a registration/login/edit-profile plugin for the front end: <
It's shortcode based so all you have to do is redirect your users to the register page where you have [wppb_register] shortcode. Create register/login/edit-profile pages for each site you need and that's it. | stackexchange-wordpress | {

Why doesn't the "Remember Me" checkbox work for me on a live website? Only works on a local server environment
If I check "Remember Me", and then log out, my login and password are **not** remembered. I've tested this on many WordPress sites running WP 3.2.1 on a server here in NZ and also on a completely different server hosted in the US. It doesn't appear to be a problem with just my browser, as quite a few people have tested this for me. Although I have tried clearing all cookies, cache etc.
It **does** however work locally with a MAMP setup on OS X. Is there something I need to install on the server to get this working? I presume it's using session cookies? Any ideas? | Check your browser settings. You can change the settings for size and time to keep the cookies. | stackexchange-wordpress | {

How to remove "Read on" content in the_excerpt?
I know the_content has the handy dandy $strip_teaser argument that lets you set whether there is "continue reading" text. No such luck for the_excerpt...
I would like to just get rid of it. I had previously tried to just shorten it to Read on but that didn't seem to work either.
function beernews_auto_excerpt_more( $more ) {
return ' …' . __( 'Read on <span class="meta-nav">→</span>', 'twentyeleven' ) . '</a>';
}
add_filter( 'excerpt_more', 'beernews_auto_excerpt_more' );
Theme is Twenty Eleven. | If you're using the Twenty Eleven theme I think you need to remove that theme's filter before you can define your own:
remove_filter( 'excerpt_more', 'twentyeleven_auto_excerpt_more' );
_edit_ building from t-p
try this:
add_action( 'after_setup_theme', 'my_child_theme_setup' );
function my_child_theme_setup() {
remove_filter( 'excerpt_more', 'twentyten_auto_excerpt_more' );
}

WordPress in a sub directory but not images

how to add the same Widget twice to a sidebar?

Creating / Editing a post from within site template
I am developing a website that will allow multiple users to author short posts (Kind of like a job board) and I want to know how they can author or edit these posts from within the site template (Ie; without having to enter the dashboard).

The_content display a different content from a previous loop
I have custom template for my homepage. If i just put the_content(); to this template, nothing else, then it will display my text i entered in my admin panel in the editor. But if i have a different loop in my template, its display the content from an other post.
<?php
query_posts( array(
'post_type' => array(
'movies'
)
));
if (have_posts()) : while (have_posts()) : the_post(); ?>
asd
<?php endwhile; endif; ?>
<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; ?>
So the the_content(); part in the end is displaying the content from the previous loop. What should i do to fix this? | Try rewinding the Loop, via `rewind_posts()`, between the two loops?

get_query_var() and permalinks
I have a permalink structure that looks like this,
%category%/%postname%
I have a category.php template coded up and and trying to pull of the post of a certain category, so for example my URL may look like this,
/category/category1
I want all posts that are in category1 to be return however, when using the following code I get null returned,
`get_query_var('cat')`
I assume that this code is looking for URL that looks like this,
?cat=category1
So how do I make it work with permalinks? | WordPress rewrites rules invisibly translate pretty permalinks to the non-pretty format internally, and set the appropriate variables and load the requested page, you don't need to do anything in your template to load posts from a category on a category page.
The `cat` query var specifically will be set to the _ID_ of the requested category, not the name.
That said, this:
$my_category = get_query_var('cat');
echo $my_category;
_should_ print the selected category ID on a category page. If it's not, we'd have to see your code to help you further.
Also, have a look at the `$wp_query` global to see all query vars set on a particular page:
