How to have "the most used tags" taxonomy always expanded?
How can I have some taxonomies to always have "the most used tags" displayed when a new post is being created.
Thanks. | There does not appear to be any way to hook into that from inside PHP
<
So JavaScript will probably best suit as a quick and easy solution.
add_action( 'admin_footer-post-new.php', 'wpse_45149_inject_script' );
function wpse_45149_inject_script() {
$expand_for = array( 'post_tag' ); // add taxonomy names here
// build a nice jQuery query
foreach ( $expand_for as &$tax_name ) $tax_name = '#link-'.$tax_name;
$expand_for = implode( ',', $expand_for );
?>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('<?php echo $expand_for; ?>').click();
})
</script>
<?php
}
You should probably `wp_enqueue_script` this script instead (always set position to "footer"). And also hook to the `edit.php` pages if necessary. Moreover, `$expanded_for` should probably be escaped. | stackexchange-wordpress | {

How to grab data (titles, thumbnails and custom fields) from multiple posts to populate a new array efficiently?
I need to know the most efficient method to grab 3 pieces of data from from multiple posts:
* Post title
* Thumbnail
* Custom Field
I am attempting to build a Google map of posts using data stored in WP posts. Each post has geo coordinates and a thumbnail. I want to pull the title, geo custom field and thumbnail and use this data to build points of interest on a map. The posts are stored as a custom post type called listings.
Here is a demo: <
Here is my query code:
$args=array( 'showposts' => 45 );
query_posts( $args );
Currently this is failing to query anymore than 45 posts. I have over 400 listings that I would like to query. Not sure why it's failing. | Sorry! Turns out the problem with query_posts failing here was due to my PHP memory_limit. I changed it from 8mb to 128mb and the problem goes away. | stackexchange-wordpress | {

Multisite Pull Recent Image Attachments from Blog ID
I am creating a WordPress network and am looking for a way to pull recent images from the sub blogs, but I am having some trouble doing so.
What is the easiest way to make this happen? | Use `switch_to_blog` to switch blog contexts to a specific blog ID. From there on it's all down to `get_posts` of the `attachment` type. And switching back to the current context with `restore_current_blog`.
Something like this:
switch_to_blog( $blog_id );
$args = array( 'post_type' => 'attachment', 'numberposts' => 5, 'orderby' => 'post_date', 'order'=> 'ASC' );
foreach ( get_posts( $args ) as $attachment ) {

Prevent access to single post types
Say that I want to make a post type called 'press' and it is mostly concerned with linking a title with a PDF document of a press clipping. I want to show all of these as an archive... so something like site.com/press but i don't want any single post template pages. so no site.com/press/article1 or site.com/press/article2. other than not including a link in my archive template (which just obscures it but doesn't negate their existence or prevent access to the single posts) how can i prevent a visitor from inadvertently accessing the single posts. how could i re-direct them back to the /press archive? | ## The fast way
In your .htaccess add a rule
RedirectMatch Permanent ^/press/.+ /press/
## Plugin way
Hook into `template_redirect` and redirect all requests to a single entry:
add_action( 'template_redirect', 'wpse_45164_redirect_press' );
function wpse_45164_redirect_press()
{
if ( ! is_singular( 'press' ) )
return;
wp_redirect( get_post_type_archive_link( 'press' ), 301 );

Generate multiple tag query URLs
As we know WordPress supports multiple tag queries (',' and '+'). The only problem with this `add_query_arg()` doesn't handle these methods if a query param is already exists in the URL.
From the following url `www.domain.com?post_type=ptype¶m=value1 add_query_arg('param', 'value2')` will generate `www.domain.com?post_type=ptype¶m=value2` insead of `www.domain.com?post_type=ptype¶m=value1,value2` or `value1+value2`
I would only use comma separated (OR) method. Could you please help me to write a function which adds additional param value next to an exsisting one? regular expressions perhaps? | $url = parse_url( $your_url );
$query = $url['query'];
$args_arr = array();
parse_str( $query, $args_arr );
if( isset( $args_arr['param'] ) ) {
$query_string = $args_arr['param'];
$query_string .= ',value2';
} else {
$query_string = 'value2';
}
add_query_arg( 'param', $query_string );
That's completely untested, but you get the concept. Basically, wordpress is gonna want to replace what you have set in `param`, so you need to get what you have in param, then add what you want to add to it. You can definitely make that into a function if you want to, depends on your usage case. | stackexchange-wordpress | {

Form validation on user profile edit
I have added a custom field to user profiles in bbPress however I am unsure how to do form validation other than javascript. I would like to do some PHP validation however the few things I have tried didn't work.

$myErrors = new WP_Error();
$myErrors->add('id_error', __('Test error.',""));
bbp_add_error( 'bbp_steamid_invalid', __( '<strong>ERROR</strong>: The ID you entered is invalid.', 'bbpress' ) );

Return all custom meta data for one custom post type

I now would like to add a page to my site which shows ALL the names on a map based on their latitude and longitude.
I obviously know how to get single values out and get them on a map, but I'm not that experienced in Wordpress so I'm not sure what the best way would be to get all this information out in a structured way for what I'm trying to do. Any pointers to get me started would be appreciated. | If all of your custom post type posts have all meta fields that you need then you can use the `fields` argument and set it to `ids` which will work much faster for example:
//get your custom posts ids as an array
$posts = get_posts(array(
'post_type' => 'your_post_type',
'post_status' => 'publish',
'posts_per_page' => -1,
'fields' => 'ids'
)
);
//loop over each post
foreach($posts as $p){
//get the meta you need form each post
$long = get_post_meta($p,"longitude-key",true);
$lati = get_post_meta($p,"latitude-key",true);
$name = get_post_meta($p,"name-key",true);

It's free and allows you to add custom upload fields and all kinds of goodies to your edit screens without touching code. It's called Advanced Custom Fields.

How to create a Wordpress plugin for another wordpress plugin?
I always do changes on the Wordpress plugins for clients. But these changes are always in danger to be lost if the plugin is updated.
Is there is a way to make a plugin for another plugin in Wordpress? Is there is a way to preserve the changes or re-apply it after each plugin update. | I think best way to do this is via actions and filters, like we extend WordPress core itself.
Other options is like @helgatheviking pointed, if plugin is class you can extend it.
Unfortunately not all plugin developers provide useful filters and actions with their code, most often plugin isn't written in OOP manner. Only way to save your modifications on plugin update, is to create copy of original plugin, change plugin name. I usually prefix original name e.g. `Mamaduka Twitter Connect`, but with this solution you'll need to manually update original plugin's code.
If you think that plugin needs more filters/action, you can contact the author and ask him to include those hooks into the core. | stackexchange-wordpress | {

wp_mail_from not changing from address

I have also been told by others that the WP SMTP plugin is needed to get email working on Windows hosts and is not needed if running your website on Linux.

How to load a post into an empty div tag anywhere across the pages?
Absolute beginner question: I need to load text into specific div tags across the page. On my html mockup its a lorem ispum text box waiting for wordpress to load the real content. So, how do i control the real content and its relation with the div box text on the page? Can it be a post, so i can manage it from the dashboard? Thanks in advance. | You can solve this in different ways.
One it's to use simple querys with WP_Query and using the **p** parameter to retrive a particular post like it's explained here. Something like this:
$the_query = new WP_Query( 'p=123' );
while ( $the_query->have_posts() ) : $the_query->the_post();
the_content();
endwhile;
Where 123 it's the post id from where you need the data (the_content).
Or you can query the content from a single post using get_post function. Like this:
$postid = 123;
$queryp = get_post($postid);
$content = $queryp->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
echo $content;
Where 123, again, it's the postid from where you need to extract the content.
And i think wp_get_single_post function should work too.
Then you can control your content everywhere just extracting the desired data from certains posts by postid | stackexchange-wordpress | {

What is the advantage of using wp_mail?
What is the advantage of using `wp_mail()` over `mail()`. Codex says they're similar, but they seem to be _very_ similar. | `wp_mail()` is a pluggable function: It can be replaced by plugins. That’s useful in cases where the regular `mail()` doesn’t work (good enough), for example when you need extra authentication details. Example: WP Mail SMTP
`wp_mail()` uses PHPMailer by default, a sophisticated PHP class which offers a lot of useful preprocessing and workarounds for cases where `mail()` is too simple (UTF-8 encoded subject lines, attachments and so on). Just take a look at the bug tracker to get an idea about the complexity of these tasks.
`wp_mail` offers some hooks for other plugins to change different values:
* `'wp_mail'`
* `'wp_mail_from'`
* `'wp_mail_from_name'` use case
* `'wp_mail_content_type'`
* `'wp_mail_charset'`
* `'phpmailer_init'` _(an action)_
In short: **Use`wp_mail()` for interoperability.** | stackexchange-wordpress | {

What is the difference between the "wp_footer" and "get_footer" actions?
I am working on developing a plugin, and I am trying to add a line of text to the bottom of the page, I see there are two actions that seems reasonable, `wp_footer()` and `get_footer()`. wp_footer sounds like it may more suited towards code that needs to go at the very end of the page (like JavaScript files), but get_footer didn't have any documentation on its wordpress codex page. Which should I use for something like this? | These two functions accomplish two different things. `wp_footer()` is a hook used in your footer.php template file to ensure that the right code is inserted (from the core/plugins/etc) into the right place. `get_footer()` is used in your other template files to call for the code in your footer.php template file.
So in simpler words `wp_footer()` gets other code that you most likely don't produce (but need), so it's a little more abstract. `get_footer()` grabs the exact code that you wrote into your footer.php file so it is the WordPress version of PHP's `include()` function.

Should Plugin Folders Include a Blank index.php File?

A second issue is performance: WordPress **scans all PHP files in a plugin’s root directory** to find plugin headers. This allows you to have multiple plugins under the same directory, eg `/wp-content/plugins/wpse-examples/`.
It also means that unused PHP files in that directory are wasting time and memory when WordPress is searching for plugins. One file will not do much harm, but imagine this is getting a common practice. You are creating a real problem in an attempt to fix a fictional. | stackexchange-wordpress | {

how can I add a "read more" tag directly in the template?
how can I add a <\--more--> tag directly in the template? I mean, the exact php code to use in a template for that shortcode. I need it for a script that makes use of that shortcode to hide content and having to add the "more" shortcode by hand through all the posts would be such a task

Multiple post back-to-back display only one gallery

Couldn't find a documentation for a filter API in plugin development
I'm new to wordpress plugin development, I read the whole documentation this afternoon < I tried to write some code, like this in plugin file:
add_filter('the_title', 'my_own_function', 10, 2);
**Function is:**
function my_own_function($title, $post_id){
return $title. $post_id;
}
This plugin really worked, but the documentation doesn't tell the filter API `the_title` has two arguments, and what those arguments are. That's the problem! If it doesn't tell, how would I know?
**Here I just quote the official documentation relevant excerpt:**
the_title
applied to the post title retrieved from the database, prior to printing on the screen (also used in some other operations, such as trackbacks).
So, my **question is:** How can I find a full explanation of filter API such as `the_title`? Please help. | There's only one answer: **You always go and read the source code**.
There are some online tools that help you with this, specifically Adam Brown's Hooks List, which contains links to the source code where you can read what arguments filters and actions take.
Be aware that a single filter can have variable amounts of arguments depending on where it is being used. For example, in class-wp-posts-list-table.php `the_title` filter sends out one argument only, instead of two like in post-template.php

Attaching a metabox to a single post
I've been using metaboxes for a while now, and enjoyed their flexibility. However, I am now in a situation where I need the metabox to appear only for **a specific single post or page** , and **not** for the whole (custom)-post-type. Is it possible to do so?
Your kind assistance would be most welcomed.
TIA Matanya | Since you are familiar with the how to create metabox using `add_meta_box` already, I'll skip to the relevant bits.
You can either conditionally `add_meta_box` depending on the current post title, or ID, (this is the preferred method) or, you can conditionally `remove_meta_box` depending on the the post displayed.
To detect the current post ID you would `get_query_var( 'post' )` and move on from there, using `get_post(get_query_var('post'))` if further post data is required to filter out the metabox. | stackexchange-wordpress | {

I could be misunderstanding you but doubt if categories in the blog is where to go with this, CPT's do something similar but are much more flexible. If you work out a structure that suits you in terms of CPT's then getting it to display how you want on whatever template pages you want is not going to be incredibly difficult, but you need to work out the structure that you use to store them in WordPress first.

What would cause edit buttons for plugins to disappear?

wordpress alchemy put custom metabox on certain page only

<?php
$custom_mb = new WPAlchemy_MetaBox(array
(
'id' => '_custom_meta',
'title' => 'Add images to home page slider',
'template' => get_stylesheet_directory() . '/metaboxes/custom-meta.php',

));
?> | new WPAlchemy_MetaBox(array
(
'id' => '_custom_meta',
'title' => 'My Custom Meta',
'template' => STYLESHEETPATH . '/custom/meta.php',
'exclude_template' => 'product.php'
));
the 'exclude_template' would work for excluding the one's you didn't want.
new WPAlchemy_MetaBox(array
(
'id' => '_custom_meta',
'title' => 'My Custom Meta',
'template' => STYLESHEETPATH . '/custom/meta.php',
'include_template' => array('product.php','press.php') // use an array for multiple items
// 'include_template' => 'product.php,press.php' // comma separated lists work too
));
including works the same.

Permalink doesn't get displayed in Twitter button (Local WordPress problem?)
I'm trying to add a custom "Tweet this" button to my WordPress posts. I'm sticking to the official Twitter guidelines.

* ` the_permalink(); ?>`

How to translate multi-line strings?
If there is a long string in PHP like this:
<?php
$text = "Some ... very
very...
long string";
Can it be localized by GetText wrapping it in `__()`, e.g.
<?php
$text = __("Some ... very
very...
long string", "domain");
? I've heard that GetText doesn't support multi-line strings and indeed, when I try to scan such file in poEdit, it doesn't find it.
How do you deal with that? WordPress source files seem to use very long lines so is that the way to go? (Obviously apart splitting the strings into multiple smaller strings which I'd rather avoid.)
**Edit** : the problem was that I had a variable reference in my string, e.g. `__("string $someVar")` which can't be supported by GetText. My fault. | `__()` and the other l18n functions will handle any string you give them, including line breaks. In my experience, poEdit recognizes them just fine, but if you're having issues, you may consider using UNIX line break escapes `\n` instead of actual line breaks inside the strings; in this case, be sure to use double quotes, so that they're not rendered literally. | stackexchange-wordpress | {

Any Wysiwyg tool to edit wordpress site based on given theme?
I dream of a wordpress dashboard that would be mostly Wysiwyg and let the user edit a site based on a given theme.
In fact this is something I know is technically possible as I have seen it in this tool: < (see the video; it is not a wordpress tool, but it shows how one can edit a webpage underlying code with a Wysiwyg interface).
For example if I am using WooThemes Optimize, the dashboard would show me the homepage and let me edit the titles, the text in the button, the featured image, etc.
Does anyone know a tool that can do that? or any hint how I can get there? | Just found this: <
apparently they call this a "WYSIWYG theme platform".

Adjust query on single
I am building an event manager. One of the template files I have is events-single.php which displays single events. At the bottom of this I have next and previous events using `next_post_link` and `previous_post_link`. The problem is that those functions proceed through the events in order of **published date** rather than **event date**. (I have a meta key `_fulldate` setup on the CPT for this). When I was building events-archive.php file I overcame a similar problem by doing something like this
$query = new WP_Query( array (
'post_type' => 'events',
'orderby' => 'meta_value',
'meta_key' => '_fulldate',
'order' => 'ASC')
);
However when I try that on events-single.php it makes all the events display on the page.
Ultimatly I want events-single.php to behave like a single page but then allow me control over the query as above. Is this possible or will I have to do a second loop for the Previous and Next links | Take a look here: specify meta_key / meta_value condition for prev_post_link and next_post_link
Which ultimately leads to this plugin, which accesses the get_adjacent_post function mentioned above: Ambrosite Next/Previous Post Link Plus

What hooks, actions or filters i can use to customize wordpress registration page and form?
i would like to customize the design of the registration page of wordpress and also the registration form. Can i create a registration page template? or maybe tell wordpress to use a custom registration page i create. | WordPress handles registration with wp-signup.php (in the root of the installation). There are some hooks in place to allow for additional content (such as a signup header, or additional signup fields), but it doesn't support theming in the same way that other WP pages do.
BuddyPress is a pretty heavy-duty solution if all you want is a custom registration page (so I won't suggest that you install it on your site), but you might want to check out how it handles registration. Essentially, it provides its own template for registration (which you could do with a Page Template in WP), and then has some functions for handling some of the things that wp-signup.php does inline. See especially buddypress/bp-members/bp-members-signup.php. Using a totally custom registration process like this means that you can do pretty much whatever you want. | stackexchange-wordpress | {

Best Plugin to Reorder Post Types
I'm looking for a plugin that enables me to reorder pages, posts and custom post types from the normal listing in the WordPress dashboard.
The closest plugin I've found is Simple Page Ordering < however this plugin does not allow post ordering, and also does not easily allow building hierarchies.

Another plugin, CMS Tree Page View, does this very well but has its own interface, while I'd prefer using the native interface of WordPress.
Any suggestions? | I've used the below plugin and it has worked really well for me:

Upload multiple images in a custom metabox

When to use custom DB tables or add_option?
I've got a pretty straight forward question. When does it become too much data to use `add_option`, `update_option`, etc, and instead use a custom DB table?
For example, if a plugin stores thousands and thousands of characters of data using `add_option`, etc, is there a maximum it can handle before it starts to create problems?
A plugin of mine used to create its own DB table, but it created a lot of issues in which some users setups wouldn't work (especially on Microsoft based hosting servers), and many more users felt the need to contact me and advise me on using `add_option` instead. I followed their advise, and now the plugin uses these functions.
However, I've come a long way in my coding abilities since then and in-turn have started redesigning the plugin. It now has much, much more data to be stored using `add_option`. Even up to over 10000+ characters worth, and I'm beginning to wonder if it will cause any problems. | For the record, I will **_never_** encourage developers to use custom database tables. Yes, they're easy to use, but you lose 100% of the data abstraction provided by WordPress.
`add_option()`/`update_option()`/`get_option()` are basic key-value functions. They store data in a MySQL LONGTEXT field. LONGTEXT can store over 4 million characters ... so a 10000+ character option is definitely possible. | stackexchange-wordpress | {

Creating my own portfolio custom-type
I'm using WordPress to build my photography portfolio. So far I've created a _Custom Post Type_ called `session` for each photo session, and I've managed to list all the sessions with each thumbnail in the home page.
Now, however, I have to create the content of each `session`. I'd like to keep it simple:
* The title
* A small description (if any).
* A set of pictures, that should appear straightaway in the post.
The problem is that I don't know how to face the inclusion of the images. Looks like using a _gallery_ is not what I'm looking for, because it generates a set of thumbnails, and I just want the images in full size in the post.
What's the best way of doing this? The ideal case would be to have something like `the_images_of_this_post()` so I could place them at will from the template file.
Thanks! | Attachments are post objects, with `post_parent` set to the ID of the post they belong to (ie your 'session').

how to programmatically change post tags
Is there a php function which can add/remove tags of posts? If not how would I do this?
I am looking for something like this:
add_tag($post_id, 'tag-name');
remove_tag($post_id, 'tag-name'); | The key function you're looking for here is `wp_set_post_tags()`.
To add the tag 'awesome' to post 98,
wp_set_post_tags( 98, array( 'awesome' ), true );
Note that the `true` parameter means that this tag will be added to the existing post tags. If you omit this value, it defaults to `false`, and the existing post tags will be overwritten with the new ones being passed.
To delete a tag, first pull up a list of the existing post tags using <
$tags = wp_get_post_tags( 98 );
Then assemble a list of the tags you want to keep (which will exclude the one you're "deleting"), and replace the existing post tags with the new list:

$tags_to_keep = array();
foreach ( $tags as $t ) {
if ( !in_array( $t->name, $tags_to_delete ) ) {

As JohnG said, you _have_ to pass the ID of the current post to `get_the_post_thumbnail()` (the `the_post_thumbnail()` function already handles that for you). The Function Reference in the WordPress Codex has many usage examples:
get_the_post_thumbnail($id); // without parameter -> Thumbnail
get_the_post_thumbnail($id, 'thumbnail'); // Thumbnail
get_the_post_thumbnail($id, 'medium'); // Medium resolution
get_the_post_thumbnail($id, 'large'); // Large resolution
get_the_post_thumbnail($id, array(100,100) ); // Other resolutions

Getting rid of files not used by latest upgrade

* wp-admin\css\login.css
* wp-admin\css\ms.css
* wp-admin\css\nav-menu-rtl.css | For several versions already core updates are partial (differential). Only changed files are downloaded and overwritten so it is not safe to assume that those that weren't are not used.

Proper use of wp_enqeue_style

}//if not admin ends
}//function mrskitson_load_styles ends

1. You only need to provide the script path _once_ , _either_ in the `wp_register_style()` call, _or_ in the `wp_enqueue_style()` call, but not _both_. (In fact, in this context, it would be fine to omit the `wp_register_style()` call entirely, and just use the `wp_enqueue_style()` call.)
2. You're hooking into the _wrong action_. Try hooking into `wp_enqueue_scripots` instead of into `get_header`. (Note: this will require the Theme to include a call to `<?php wp_head(); ?>` in the document head - but it should be doing so, anyway.)
Other considerations:
* For custom styles/scripts, I would recommend _prefixing_ the style slug; e.g. change `main` to `srskitson-main`. | stackexchange-wordpress | {

Easiest way to simulate WordPress's URL resolution to retrieve post ID, etc?

I realize that I can probably strip the URL and parse the domain myself, but I hope that there might be recommended WordPress methods exposed to make this more robust across URL formats. | As Weston mentioned, if you're within WordPress and you know what blog the URL came from, then ask WordPress for the blog ID.
But if you're really, really sure there's no better method in this case than parsing a URL, then here you go:
$url = '
$domain = parse_url( $url, PHP_URL_HOST );
// This could be dynamic but good enough for now
$subdomain = str_replace( '.mysite.com', '', $domain );
// Never use $blog_id for anything, you'll break tons of things
$parsed_blog_id = get_id_from_blogname( $subdomain );
// url_to_postid() only works for the current blog

$post_id = url_to_postid( $url );

Show posts of category in a page
I would like to be able to display all the posts in a certain category on a page so that all posts are on that one page and there is no pagination.
If possible, I would also like to display a short preview of the posts - all posts will have a thumbnail and a short paragraph at the start.
I've tried various different plugins, but so far none of the one's that I have found do the job.
Does anybody know of a plugin or a way to do this? Alternatively, modifying the default category pages so there is no pagination is an option if all else fails... | I found a plugin-solution eventually to the my second option. I now use Posts per cat and set it to some silly number so that all of the posts in the category display on one page; it turns out that's all I needed!

post_title is empty on global $post object
My plugin uses publish_post hook to get the post data and do some processing:
add_action('publish_post', 'publish_post');
function publish_post($post_id) {
global $post, $blog_id;
$author = get_userdata ($post->post_author);
$title = $post->post_title;
//some processing here...
}
I notice that for a new post, $title is always blank, while all other fields are available. If I publish the post again (update), then the title becomes available.
**Edit**
I printed out the $post variable and notice that that the post_status is draft:
[post_title] =>
[post_excerpt] =>
[post_status] => draft
So it seems the $post variable contains what was loaded from the database, but not what is currently on the screen. How should I get the $post that reflects what is currently on the screen? Is there a hook that fires after a post is saved to the database? | This hook is called like this:
do_action("{$new_status}_{$post->post_type}", $post->ID, $post);
My guess is that you should be using data passed as second `$post` argument, rather than global.
So:
add_action('publish_post', 'publish_post', 10, 2 );
function publish_post($post_id, $post) {

Show validation warning if no Excerpt is added
Is it possible to display a warning in the admin section when posting if the excerpt section hasn't been filled out to stop a post being published without an excerpt?
Does anyone know of a plugin that has this facility? | Writing your own plugin will help you understand WordPress better, subsequently enjoying it even more, beside you look like you are quite capable with some tiny bit of PHP, no?
When saving a post, the `save_post` hook is pulled on. This passes along the `$post_ID` and the `$post` variables, containing everything you need to check for `post_excerpt` (like `if ( strlen( $post->post_excerpt ) < 10 ) ...`).
If you want to explicitly do this only when a post is published you can hook to `{$old_status}_to_{$new_status}` hook.
To show a nice message or warning, tap into the `post_updated_messages` hook. You can alter the `$_GET['message']` variable inside the `redirect_post_location` filter.
Alternatively, you can display the warning on the page at all times just by looking at the `$post->post_excerpt` property. Style it as an alert or use jQuery to remove the publish button altogether until the field is filled. Lots of options, depends on how far you're willing to take it. | stackexchange-wordpress | {

wp_insert_link not working

How do I get posts that have a thumbnail in WP_Query?

Problem with permissions in wp-content/plugins
I have a WP installation on my local machine and trying to get my hands dirty with plugins. I wish to clone a project from github which has this plugin code. However, i dont have the permissions inside plugins to do this as a normal user without su priveleges. (of course i can become root and do this but i dont think thats the way it should be).
Then by default the folders in a WP installation have group set to "tape", which appears strange to me.
What exactly should be the right permissions for the internal folders on a local WP installation? | Best thing to do is check the WP docs themselves for correct file/folder permissions and how to change them, if needed: <
> Typically, all files should be owned by your user (ftp) account on your web server, and should be writable by that account. On shared hosts, files should never be owned by the web server process itself (sometimes this is www, or apache, or nobody user).
Is "tape" a local user name? Or FTP name?
Depending on what kind of system you're using - a local install of apache, php and mysql - or a stack like Bitnami, XAMPP or MAMP, there may be slightly different owners and groups for folders and users. | stackexchange-wordpress | {

What problems maybe happen if I remove "wp-" prefix from wordpress folders and files?
I want to hide wordpress signs from my site. So I don't want other people know that I built the website via WordPress. So I decided to remove `wp-` prefixes from all wordpress folders and files.

Disable Comments Feed
I am working on a private site where the comments need to be hidden.

Using wp-postratings to rate user on profile pages
I'm using wp-postratings on my site and I want to include it on the buddypress profiles of my members so other users can rate them. I place the function on the profile page but it doesn't do anything when a rating is clicked. Any ideas on what I can add to make it work? | It's likely that it will not be as easy as adding something small to make it work.
Plugins like WP-Postratings store their data on a post-by-post basis. But BP members are not posts. So you would have to intercept the way in which the plugin stores its ratings data natively, and save it to users instead.
Moreover, you'll have to modify/extend the markup and JavaScript created by WP-Postratings so that the current "item" being rated on is the member's user id, rather than the post id. Then, because the rating happens via AJAX, you'll have to make sure that the new id is sent properly in the request, and that the server-side handler is set up to expect member data rather than post data. | stackexchange-wordpress | {

Setting image upload absolute path?
In anticipation of a major upgrade, I moved the webroot from `site_v1` to `site_v2`. The public url for the WP 3.3.1 install is still example.com/ (no change). I did a tar copy from the /site_v1 dir to the new /site_v2 dir.
The WP installation is working well from its new Linux path of /site_v2 instead of site_v1. All pre-existing images continue to work fine etc.
**The Problem** is that when new image files are uploaded using either the flash or classic uploader, the files themselves are put into /site_v1/wp-content/uploads/2012/03 instead of the correct /site_v2/wp-content/uploads/2012/03 location.

Wordpress Custom Post Type Children Template
I have created a hierarchical custom post type in wordpress called "films." It is hierarchical so it can have children elements.
When a "film" is clicked, wordpress automatically uses the template called 'single-films.php'. That is great, but I wish to use a different template when one of the film's children pages is clicked. For instance, a child of a film might be "press." When that film's press link is clicked, I want it to use a different template than single-films.php.
I was hoping there is some way I can use a template like single-children-films.php. Any ideas how I can change a hierarchical custom post type's children template? | If, from within `single-films.php` you filter based on the parent post you should have little issue with this. For example:
if( $post->post_parent != 0 ) {
// not top level
} else {
// top level page
}
If you need to know how deep the page is, that's a different matter, but that's also doable (unfortunately it means you need to query the database though). | stackexchange-wordpress | {

wp_head function outputs after <head>

$tracking_code = $mytheme_option['tracking_code_head'];
if($tracking_code){
echo '$tracking_code';

The problem is that the output comes right after the tag. I'm not sure what the problem is? wp_head is placed last in head-section. | `'$tracking_code'` ist just a string. It closes `<head>` automatically. So, no, it doesn’t come after the `head`, you just failed to use **source view**. Firebug and similar tools show just the rendered DOM, that’s not good enough.

<
It allows you to control the aspect of every comment, also the replies. Then, you define a callback function, which will be called when Wordpress creates each comment.
Your callback needs to start like this:
function commnents_callback($comment, $args, $depth) {
$GLOBALS['comment'] = $comment;
global $post;
// your HTML + PHP comment creation code here
}
Then, you can create the comments by using this code:
<?php if( $comments ): ?>
<ul>
<?php wp_list_comments('type=comment&callback=commnents_callback'); ?>
</ul>
<?php endif; ?>

Display all search results
Is there a way to display all the search results on the `search.php`? Actually it is displaying only 10 results (as set in `WordPress settings > general`). | The quick and dirty way to do it would be to use `query_posts` again, doubling the number of database calls.
<?php if (have_posts()) : ?>
<?php query_posts('showposts=999'); ?>
Better would be to add this to `functions.php`, altering the original query before it is executed:
function change_wp_search_size($query) {
if ( $query->is_search ) // Make sure it is a search page
$query->query_vars['posts_per_page'] = 10; // Change 10 to the number of posts you would like to show
return $query; // Return our modified query variables
}

How can I get multisite primary blog (url or path) for current user?

How to add inline css code with background image in page html code?
I want to add inline css code inside a page of my blog. This css code calls an image as background of a div.
Is this possible? and how to do that?
I have tried to add the image as a Media resource, and got a URL for it, but using this URL does not seem to work.
Example of code that I paste to my page html:
<p><a href=" style="width: 90%;
font-family: Helvetica, Arial, sans-serif;
background: #0e710d url( 0 0 repeat-x;
font-size: 1.6em;
">
Click here »</a></p> | cant you just give that link a class? why touch your template files?..
anyhow i see no reason why you can't to that... the css should work..
The only change i would do when editing a template file is
using php to get the folder url (where you image is) like so:
<style type="text/css">
.specialLink a {
width: 90%;
font-family: Helvetica, Arial, sans-serif;
background: #0e710d url("<?php get_bloginfo('url'); ?>/wp-content/uploads/2012/03/image.png") repeat-x 0 0;
font-size: 1.6em;
}
</style>
<p class="specialLink"><a href=" here »</a></p>
**Again... i reccomend you use your style.css to load that css and not in
template files.. if you need it just for a specific page say so... i have
a better solution for that.**
