How to make certain page templates visible to admin only
Making a site for a client, I have some pages that the client won't be able to edit or delete. These pages rely on specific page templates.
However, I don't want these templates to be available for the client when creating new pages. Is there someway to hide these certain page template from the page attributes dropdown when creating new pages?
Thanks | Rather than defining them as custom page templates, you have an alternative.
Use the page specific templates, e.g. for a profile page, with the slug `profile` you could create a `page-profile.php` in your theme, or you can use `page-21.php` where `21` is the ID of that page/post. | stackexchange-wordpress | {

Rename page URL
I have the following URL structure:
`id` specifies the `id` of the post.
`gallery` is a normal page inside which I am accessing the `id` of the post and fetching the attachment images using `WP_Query()`.
I want to replace the URL of this page to:
in which the parameters `place` and `new-delhi` may vary in multiple other options and `topic` is the keyword which remains the same.
I have tried using some unfruitful `.htaccess` file code.
Can anyone please help? | I have tried some add_rewrite_rule magic and query variables and it worked. Thanks for the help everyone.
If in case anyone want to refer the answer:

$query_vars[] = 'custom_gallery_id';

'topic/([^/]+)/([^/]+)/gallery/([0-9]+)/?$',
'index.php?pagename=gallery&custom_gallery_id=$matches[3]',

Remove some pages from search
On my site, I want some pages to not be queriable by the search form (so they don't appear when I've got something like www.ex.com/?s=banana)
Is there a way to "Remove" pages from the search results page (without just blindly do a condition of if is_page(id), display:none) | In WP_Query() there is a 'post__not_in' argument where you can exclude specific post ID's.
You would create a new WP_Query inside of your search.php and use the current $query_args, then add on your 'post__not_in'.
If you wanted to make it more dynamic, you could also build in some post meta where you could do a meta query and exclude all that have "exclude" checked. (look up 'register_meta_box_cb' in register_post_type ).
For example,
add_action('pre_get_posts','wpse67626_exclude_posts_from_search');
function wpse67626_exclude_posts_from_search( $query ){
if( $query->is_main_query() && is_search() ){
//Exclude posts by ID

How to replace or display the special characters from JSON API plugin
!enter image description hereI started using the JSON API plugin. It works good ! But the problem i am facing is, If i enter any text containing special characters through CMS The output is not same as the given text. Why this is happening?
Example: It's a good app (Input) The output looks like It ' s a good app. Please suggest any tips/methods to get rid of this situation.
Eagerly waiting for your response. Thank you | That's probably because the "JSON API plugin" htmlescapes your text. So if you would just display it on site it should print OK, but if you need to work with it on the backend than just use `html_entity_decode()` | stackexchange-wordpress | {

Use wp init hook to call other hooks?
I want to know if it is a good practice according to WordPress theme or plugin development.
add_action('init','all_my_hooks');
function all_my_hooks(){
// some initialization stuff here and then
add_action('admin_init',-----);
add_action('admin_menu',----);
// more like so
}
thanks | In general: Yes, wait for a dedicated hook to start your own code. Never just throw an object instance into the global namespace. But `init` is rarely necessary.
You hook in as late as possible. If your first code runs on `wp_head` do not use an earlier hook. You can even cascade hooks:
add_action( 'wp_head', 'first_callback' );
function first_callback()
{
// do something
// then
add_action( 'wp_footer', 'second_callback' );
}
Regarding the `init` hook: Use `wp_loaded` instead. That runs after `init` and after `ms_site_check()` was called. This way you avoid to run your plugin on an invalid sub site in a multi-site installation. Everything else is the same. | stackexchange-wordpress | {

Facebook 'Share' and 'Like' on individual posts
As the name of the thread indicates, I want to add to my website a Facebook 'Share' and 'Like' buttons to each of my individual posts. On each post page I will have those two buttons so people can like or share that individual page.

register_post_status and show_in_admin_all_list
I have a custom post status which should be public visible but not displayed in the "all" list of the edit screen.
This is how I register the post status:
register_post_status('my_custom_post_status', array(
'label' => __('The Label', 'domain'),
'public' => true,
'exclude_from_search' => true,
'show_in_admin_all_list' => false,
'label_count' => //blablabla
));
The `show_in_admin_all_list = false` should hide the status in the all-list but it doesn't. Only if I set the public to false it is not visible. But I need `public = true`!
Any ideas

register_post_status('my_custom_post_status', array(
'label' => __('The Label', 'domain'),

Why are navigation items saved in the database?
Maybe I am just not grasping the concept of WP right here but why is everything in Wordpress stored as a post of some type? I have a custom set of tables that house hundreds and thousands of items. I would like to programatically create a navigation menu that dynamically updates items to reflect my custom tables. I haven't been able to find a way to do this without using the following function:
wp_update_nav_menu_item()
To my understanding this function stores the item in the array in the wordpress tables as posts/taxonomies? This is needless overhead in my case and looks pretty permanent. My menu items will change pretty much on a daily basis, I don't want to grab items from one table only to have them stored in another table.
Does anyone know how I could directly update the navigation menu each time the homepage loads without requiring any interference from the administration panel?
Thanks. | Filter `wp_nav_menu_objects` and add your custom items dynamically (see this example or this). You get the current list of items and the arguments `wp_nav_menu()` was with as parameters. Then you can just add new items or remove existing ones. | stackexchange-wordpress | {

What is wrong with using add_option with Multisite instead of add_blog_option in a plugin
I'm working on a new plugin but it's my first to save which will save an option to the database.
Currently I'm using `add_option` and I assumed that
\- activation would fail or \- the wrong value would be saved to the wp_blogID_options table
because I wasn't using `add_blog_option`. All the posts / literature (Wrox, Apress, etc) I've read say I need to use to `add_blog_option`.
But all my testing (and inspecting the SQL table) are proved me wrong. So ... What is wrong with using add_option instead of add_blog_option when making a plugin (that can be single install or multisite)?
To me ... it seems that `add_option` (or even `get_option`) all work fine. I'm guessing the Settings API has some protection wrapper.
However ... that would mean using `add_blog_option` (or get_blog_option) are only for 'purists'. | What I've come to 'learn' is that there are 3 states on plugin activation for a mulitsite setup.
Consider this for a Site Admin who installs a new plugin:
1. Plugin is network activated - but it needs admin to complete setup (call it stateless)
2. Plugin activated, no 'unique features' per blog and it doesn't need an admin user to complete setup (call it active)
3. Plugin activated, has unique features per blog and it does need an admin user to complete setup (call it pending)
Scenario 1: you can safely use 'add_option' on plugin activation (or network activation) as the plugin is _stateless_.
Scenario 2: you must use 'add_blog_option' and loop through each blog - if you do _network activation_ as the plugin will be _active_.
Scenario 3: you must use 'add_blog_option' and ideally you don't allow _network activation_ because the plugin is _pending_.
In my case, my plugin does nothing until the Blog owner creates a page with the shortcode. | stackexchange-wordpress | {

how would I create a custom query to get all users, and a related post based on a postmeta field?
I have about 50 users. Its pretty easy to list them all. However they are related to a special custom post type through a postmeta field called wpp_agents.
So I need to list Users, but also the post title(linked to the post).
1. User 1 | User 1's Post(linked)
2. User 2 | User 2's Post(linked)
3. etc...
I am a mysql noob but getting pretty ok with php.
Here is what I am playing with:
$data = $wpdb->get_results(
"SELECT $wpdb->users*,
"SELECT display_name, user_email
FROM $wpdb->users
LEFT JOIN $wpdb->usermeta ON
user.ID=wpp_agents;",
ARRAY_A
);
but its not right.
I believe I need to SELECT * FROM $wpdb->users LEFT JOIN $wpdb->postmeta
but then not sure.
any help is greatly appreciated. | Gladly there's a function that will output **exactly that query string** for you (still laughing about it :) ).
Here it is: `get_posts_by_author_sql` @queryposts.com, which looks in the core source like this.
In detail it builds the `WHERE` part for you, that you can drop into your query.
So just throw the user ID in and build your string that you can use in your query:
foreach ( $users as $user )
{
$where = get_posts_by_author_sql( 'wpp_agents', true, $user->ID );
echo '<pre>';
var_dump( $where );
echo '</pre>';
}
Take a look at this question on how to intercept the `posts_clauses` (or even better the `posts_where`) filter.
Maybe you find a way to simply alter the main query to spit this out on a single call. Hint: You should have some serious caching mechanism or add the result as transient. This can get intense. | stackexchange-wordpress | {

Building an email signup form. Where should the information be saved in the DB?
I would like to try build a simple plugin that collects and stores the name and email address of the person who filled in the form. I realize there are probably dozens of plugins out there that do this already but would like to build my own, for practice.
If the user enters their name and email address, where should this be stored? Should it be created as a "subscriber" custom post type or a whole new table in the WP database? What are your thoughts? I'd like to eventually export the data to a .csv file if that influences where it should be stored. | There are multiple storage mechanisms in WP so it can be bit tricky to pick one and sometimes there is no single right choice.
Let's examine your criteria for storage:
* persistent (you don't want data just evaporating)
* processable (you want to export it and probably navigate)
* simple to implement (you don't want go building something (semi)custom just for the heck of it)
* extensible (in case you want to capture more data down the road and such)
As for me the best storage to satisfy these condition would be using custom post type. It comes with a lot of functionality out of the box (like admin interface), requires no messing with storage (custom tables or whatever) and is perfectly suited to store arbitrary information in custom fields. | stackexchange-wordpress | {

Should I _split_ the result? | Filter `'img_caption_shortcode'`. You get three arguments: an empty string, the attributes (including the attachment id), and the caption content. If you return anything but an empty string WordPress will print your return value instead of its own code.

Hide php Notices in Dashboard
When I program a theme, I put WP-DEBUG on. Which ensure a proper PHP code.

I'm exporting a Wordpress site from localhost to a web host, and I am unable to import the Media Library, as the web host is unable to contact localhost.
I've uploaded all of the localhost files from /wp-content/uploads/..., and I'm thinking I just need to isolate the part of the MySQL database which contains the Media Library, and adjust the URL, then import the SQL into the web host database.
Can you tell me where the Media Library lives in the MySQL database please? | The Media Library lives in both **wp_posts** and **wp_postmeta**.
* **wp_postmeta** contains the image URL
* **wp_posts** contains an entry for each image insertion into a post, along with the post ID.
Exporting and importing these 2 tables as SQL did not work for me - I received 'duplicate entry for key 7'...
Exporting and importing these 2 tables as CSV _did_ work, using "CSV using load data".

Get the name an the description of a link category
I have a link category with the id `$id=23;` and the slug `$slug=friends;`. I managed to read all links from that category using `get_bookmarks($id)`.
Now I also want to use the name and the description ob the link category. How geht I get these values? I tried for example:
$cat = get_the_category($id);
$output .= "<p>Description: ".$cat[0]->category_description."</p>";
unfortunately this (and other things) did not work.
So how can I receive the name and the description ob the link category with the id=23? Is it also possible to recieve this via the slug of the link category? I tried `get_category_by_slug($slug)`, but this always gave an empty result,... | <

Creating a nav menu
I am not very familiar with WordPress so my knowledge with this is limited. I am working on a travel website where I need to show navigation menu and I am not sure how I can achieve the desired behavior. Here is my case:
I need to show destination based drop-down menu and another as category based. Like
Destinations
-Delhi
-Destination1
-Destination2
-More Destinations
-Mumbai
-Destination1
-Destination2
-More Destinations
More
For categories I need to show them as
Category
-Adventure
-Hills
-Romantic
-More
For category part I can create a parent category with child categories and can assign categories to posts as applicable but now sure how to achieve hierarchical menu structure for destination part.
Is there anything like hierarchical tags in Wordpress or what are the possible ways to achieve this?
Thanks in advance | First, be sure your theme supports `wp_nav_menu` which is goes into a template file - such as header.php - with the template tag function
`<?php wp_nav_menu( $args ); ?>`
which also requires a function in functions.php. See <
That will initiate the WordPress 3 menu system that will appear in Dashboard>>Appearance>>Menus
Next, read < on how to make a menu with custom links that point to each category permalink, i.e. `yourdomain.com/category/mycategoryname`

How to add orderby parameter for sorting on category.php
I'm on a Category.php page which does the loop like this:
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
I usually do a custom loop like this:
<?php //Define the Loop
$temp = $wp_query;
$wp_query= null;
$wp_query = new WP_Query();
$wp_query->query('posts_per_page=2&orderby='.$orderBy.'&paged='.$paged);
?>
I want to add the orderby variable to the first loop (the one on category.php) but can't figure out how to implement it. | You can use the `pre_get_posts` action hook to set the order on your category archive like so:
add_action('pre_get_posts', 'filter_category_orderby');
function filter_category_orderby( $query ){
if( $query->is_category()){
$query->set('orderby', 'title');
}
}

"Conflict" with jQuery (or its plugins)?
I've been working on localhost and everything looks fine but then when I uploaded my Wordpress theme online, all of the jQuery plugin functions are undefined!
One solution that worked (which I haven't tested a lot so I still don't know if it will work in the long run) is to import the javascript file from the plugin's main website or github page. I don't really prefer this "solution."
Another is the solution here but I haven't tested this a lot also. My issue here is I've used jQuery in another theme and everything works using just `$`, but in my new theme it doesn't work with `$` and so I have to use `$j` instead. It's just that I'm very used to using just `$`.
Can someone explain this weird phenomenon? Thank you! :) | You can use `$` but it is advised you don't. Use `jQuery` or something like the example in your link, if you must use `$` you can do so like this;
$.noConflict();
jQuery(document).ready(function($) {
// $() will work as an alias for jQuery() inside of this function
});
//$ will cause problems if put here:)
To use it for just a function you can append jQuery to the end like:
(function($) {
// $() will work as an alias for jQuery()
})(jQuery); //dont forget this part | stackexchange-wordpress | {

Setting a page link in the footer?
What is the proper process for setting a page up with a link to it in the footer?
Currently, all my pages are in Appearance -> Menu...and of course displayed in the main menu.
However I want a batch of them to be in the footer.
I have decent HTML,CSS, PHP skills but new to WP. | What may be easier (if you don't necessarily want all the same menu items to appear in the footer) is to:
* Create a new menu, "Footer Menu" for example
* Add-in whatever links (pages) are needed there

Font shows up as Arial instead of Times
I am the webmaster of Palo Alto High School's online publication, The Paly Voice. We're using Wordpress, and for some reason occasionally chunks of stories change fonts. Here is an example.

1. Put the paragraphs that are showing up with the wrong font inside `<p>` tags.
2. Add a new rule in story.css for the entire section that sets the font. The rule would be something like this:
.story-content {

How to get the unfiltered excerpt, without [...] or auto-excerpting

if ( $real_excerpt ) {
echo $real_excerpt;
} // shouldn't show anything if there isn't a custom excerpt | Why don't you use the global `$post` variable? It contains an object with the content as it is on the db row corresponding to that post. Here's how to use it:

posts stuck as drafts

**Example: Next to each member in the directory I want to show the Gender they selected**

echo xprofile_get_field_data('Full Name', bp_get_member_user_id());

Two pages named the same thing, on a different level but conflicting url paths in menus and direct links

/work/

/blog/work/

Minimising number of queries on a page when using Advanced Custom Fields
I'm currently working on a site where there is extensive use of the popular Advanced Custom Fields plugin. However, as a result the page loading time can be quite slow, especially when using the Gallery plugin.
Does anyone have suggestions regarding what the best practice is with managing a large number of custom fields? In some cases I am effectively working with thousands of variables, and need to reduce the page load time from some cases around 5s.
Quite an open question I know, though really it would be great to have some suggestions regarding how number of queries in a page can be minimised (such as through directly accessing values in the database perhaps rather than relying on a plugin's APIs?). | Performance optimization doesn't really work in vaccum, it takes hands-on profiling an looking for actual bottle necks (which often turn out to be different from perceived ones).
But it general there are several approaches to the need of lots of database data:
1. Optimize fetching from database, for example by concatenating multiple requests into retrieving single larger set of data.
2. Install persistent object cache and keep data in memory for faster turnaround.
3. Cache resulting calculations or markup fragments to reduce how often they need to be retrieved and possibly making it async from actual page load. | stackexchange-wordpress | {

Get custom field from page, in a post?
I'm not quite sure how it works, if you're on a post (single.php), does it count page.php as the page it's on?
What i need to do, is get a custom field assigned to a page, from a blog post. I need it because i want the user to be able to change the "Read more" text in the post excerpt.
I could get the custom field by just using a static page id, but if the user decides to change things up the id might change, i need it to be dynamic.
What would be the best way to go about this? | I would suggest a different approach. The option for manually adding post excerpt should go in a theme option as opposed to a custom field. Also you should use this hook for modifying the excerpt's more text

Save Plugin Version Number as Option?
I seem to recall seeing a tip somewhere saying that it was a best practice to save a plugin's version number as an option. I'm working through releasing a plugin, and I'm considering whether to do it, but since all the plugin does is make a widget (right now, it literally has no other options), I'm struggling to understand what I would ever do with that option. I'm already setting a constant with the version number for use in a couple places (mostly `wp_enqueue_*`).
Can someone either point me to a good resource or explain the use cases for saving the version number as an option? | You need to save the version to the database-- aka. save it "as an option"-- so that your script has a comparison case. That is, your script should...
1. Check the database for a version number
2. Compare that version number to the new version number-- a variable or constant in your plugin file.
3. Update things if need be
4. Save the new version number to the database
If all you have is a constant in your .php file. It always matches, meaning it is pretty much useless for any automated updating. Of course, you can keep track of the plugin versions with just the constant, but the point of saving it to the database is to be able to automatically update things when needed.

How Would You Enqueue A Google Web Font?
I'm using the Rosario font from the Google Web Fonts in my theme and I want to enqueue the font so that if there was ever a plugin that used a fancy font that there wouldn't be any conflicts or wasted bandwidth.
I want to use the Normal 400, Normal 400 Italic, and Bold 700 in my theme. How should I enqueue the font? Is it worth including the last font variant in case the other script uses it?
Several options I've been thinking about:
* Single
wp_register_style( 'rosario', " );
* Combined with Handle
wp_register_style( 'rosario_400_400-italic_700', " );
* ALL together
wp_register_style( 'rosario_400', " );
wp_register_style( 'rosario_400-italic', " );
wp_register_style( 'rosario_700', " );`
The third option looks the most explicit and but the multiple calls for same font will probably be more inefficient than simply loading the font twice.
Thoughts? | You should be able to just use ` which is the "combined" URL given by Google when selecting multiple weights/styles of a font. You can then just register the font once. You don't need to over-complicate the `$handle` either, something like `google-fonts-rosario` should do just fine as long as it is unique as mentioned in the codex. | stackexchange-wordpress | {

Page downloads as file in Chrome
I'm looking to see if I could get pointers in where to look to solve this issue.
## Issue
In Chrome, viewing the blog < in Chrome v21, the page downloads as a file "download", rather than opening normally.
The rest of the site on the same server loads fine in Chrome.
All pages load fine in Firefox.
## Background
I suspected that it was something to do with the APC caching for Apache, and/or WP Super Cache. However, after disabling both, and clearing my browser cache, the problem continues. | The page is sent with:
Content-Type: application/x-gzip

Logged in user ID as post ID
Is there a way to automatically insert the current user ID as the post category name or maybe have WordPress display only the post with a category name that matches the current logged user ID?
<?php
$query = new WP_Query('category_name=current-user-id');
if($query->have_posts()) : while($query->have_posts()) : $query->the_post();
?>
<?php
the_content( __('Read the rest of this page »', 'template'));
endwhile; endif;
wp_reset_postdata();
?> | You can get information on the currently logged in user using the get_currentuserinfo() function.
For example:
<?php
global $current_user;
get_currentuserinfo();
$username = $current_user->user_login;

?>
You can then use $username or $user_id in your custom loop.

$category = $user_id;
// concatenate the query
$args = 'cat=' . $category;

Headers already sent - Wordpress core
I'm getting an error on my site regarding "headers already sent":
> Warning: Cannot modify header information - headers already sent by (output started at ........./wp-admin/menu-header.php:161) in ....../wp-includes/pluggable.php on line 881
I read the Wordpress FAQ that discusses this, but - as you can see - this error is caused by the Wordpress core (and not even at the end of a file).
Interestingly, I don't get this error on my local machine. Only on my server.
What can I do about this?
I'm running Wordpress 3.4.2 | Wordpress provides a way to prevent the header HTML from being rendered, by appending `&noheader=true` to the url.
That will cause the header HTML to wait for you to call it manually, so that you can do a redirect before that.
To later render the header HTML from your page, you'll have to use this:
if ( isset($_GET['noheader']) ) {
require_once(ABSPATH . 'wp-admin/admin-header.php');
}

Translate widget titles using qTranslate plugin
I'm actually using the qTranslate plugin to translate my website. It works really well with everything except one thing. the titles of my sidebar widgets.
Actually, to translate some words we need to put tags like this:
<!--:en-->My English Title<!--:--><!--:fr-->My French Title<!--:-->
When I use this in the content of my widget it works well. But in the title when I save the widget. It actually remove my tags and just displays:
My English TitleMy French Title
Anyone know how to fix this? | I just found the answer and instead of putting this in the Title:
<!--:en-->My English Title<!--:--><!--:fr-->My French Title<!--:-->
We need to put this code:

Combining two meta_values within one row with query
I've added two new meta_keys to the `wp_usermeta` table:
`bid_user_lat` and `bid_user_lng`
And I need to be able to get both of these values within a single row, along with the `user_id`.
`ROW - (user_id) 220 | (bid_user_lat) 45.099080 | (bid_user_lng) -140.09099`
Now comes the tricky part ... I then need to use these values within a calculated radius statement:
`( 3959 * acos( cos( radians( @lat ) ) * cos( radians( **bid_user_lat.meta_value** ) ) * cos( radians( **bid_user_lng.meta_value** ) - radians( @lng ) ) + sin( radians( @lat ) ) * sin( radians( **bid_user_lat.meta_value** ) ) ) ) AS distance`
In the end, I'm making sure that the user is within a certain radius, and if so, I will return it within the query.
**But the most important part is being able to query the`wp_usermeta` the way I need to!** | You can use the `WP_User_Query` class which works much like `WP_Query`.
The docs: <
Below is a dump of the WP_User object that it will return, in this example using:
$wp_user_search = new WP_User_Query( array( 'fields' => 'all_with_meta' ) );
$get_users = $wp_user_search->get_results();
!user var_dump
This should set you in the right direction because it was not obvious how your new meta_keys are set up and exactly how you want to run the query. The second question isn't really related to WordPress :)
If you don't want to use `WP_User_Query` you will have to use `$wpdb` which is more direct mySQL query.
it would be something like:
global $wpdb;
$get_map_user = $wpdb->get_results("SELECT * from $wpdb->usermeta WHERE meta_key = 'bid_user_lat'");
It would probably be better if you had one `meta_key` with 2 values for your long/lat, instead of 2 meta keys.

Generate featured images old posts

Adding option to Gallery shortcode
just starting out in WP dev, and I'm looking for any guidance I can get. What I'd like to do is use a hook or filter to add my own option to the core WP gallery shortcode.

So it would look something like this: `[gallery exclude="1" hide="2,3,4,5,6" link="file"]`

Dashboard widget custom positioning?

Users disappeared from wp-admin
I have a WordPress multisite network and the question is related to one of my sites on that network. The site has a login page before you can use that site.
So I created a user from wp-admin with the Subscriber role.
The idea was to let that user log in to the site but not have access to wp-admin, but it didn't work.
So I went in again as a Superadmin and changed the role to " - No role for this website - ".
It worked and that user can't access wp-admin but can still log in to the site.
Now I want to edit that user's information, but the user disappeared from the list shown in wp-admin.
My question is:
**Where do I find that user?**

Hide comments awaiting moderation from user who submitted the comments
This is a strange one. I host a website that is primarily for children. All posts are moderated. Users are required to enter a user name and location (State), but are not required to be registered and logged in to make a comment. Some users have started using a common user name, allowing them to see one another's posts while the posts are awaiting moderation. This allows them to use the posts awaiting moderation like an unmoderated chat room, until the moderator gets to the comments.
I would like to filter the comments on the posts so that only approved comments are shown, regardless of whether the user just entered a comment that is awaiting moderation.
I have looked in the wp-includes/comments.php, and in the wp-includes/post.php but haven't been able to find where to limit the comments that are seen on the posts.
Can anyone direct me further? | Check in your theme's `comments.php` for the `wp_list_comments()` function. In the Twenty Eleven theme, for example, uses a custom callback function which is in the `functions.php` file and outputs the template for comments.
Within this comments template, you can then use **`wp_get_comment_status()`** and only display a comment if it was approved. Example from the Codex:
$status = wp_get_comment_status( $comment_id );
if ( $status == "approved" ) {
// the rest of the comment loop

Wordpress plugin url for form submit
I am creating a custom plugin that has dynamic forms and I wanted to ask on how I can create a dynamic form action url.
Example is Contact Form 7, how did cf7 create the form action url without creating a new page or a file for submission?
Please share any idea on how to do something like that for plugin.
Thanks | It doesn't need a new submit URL, most of the plugins submit the form on the same page(the one on which the form was rendered), then before rendering the form they check if there is submitted data present. Then for eg. if data is present then they have to show a thankyou message & skip rendering the form, if there is no data present they will just render the form

change a post status when users update posts?

}

{
if( (current_user_can('role')) && ($data['post_type'] == 'custom_post_type') )
{
if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return;

How to format shortcode's HTML in external file

WP doesn't show Array Custom Fields?
I'm wondering why WordPress doesn't list PHP `array()` and any serialized data in Custom Fields in Admin Panel (for Pages, Posts etc.)? Only Custom Fields containing strings and numbers show up and can be edited by user manually.
Edit: Why aren't post meta values displayed if they are stored as a non-string value, meaning, stored as either arrays or a serialized value ?
Example: If a post has a meta key 'custom-meta' with a string value as 'yes', it is displayed in the meta box, but if it has an array value like `array('value' => 'yes')`, it is not displayed in the meta box.
Can I enable this? | There is no filter to change that behavior, you would have to replace the entire metabox.
On the other hand: I think there is no really simple way to show and to save those arrays.
Example for a fictive meta key `'foo'`:
array (
0 => 2,
'hello' => array (
0 => 2,
'hello' => 'world'
)
)
Creating a default interface for such an array would be very hard. This metabox is for simple fields, it should be easy to use. And you cannot just present the serialized string: editing that would probably break it. So I think it is a compromise. Better than nothing, but not perfect. | stackexchange-wordpress | {
