Use Tag input metabox style for Categories
I am using Categories to create news timelines, For example < (check the cloud at the bottom of the page for more examples)
The problem is in the Add Post screen. The Categories input metabox uses checkboxes. As the list of categories grows, scrolling through this list is becoming very timeconsuming.
I could convert the Categories to Tags (which is very easy) so that I could use the Tag input metabox, which has an ajax autocomplete, but then I would have to change the theme code to throughout the site so that it would display tags instead of categories.
So I was wondering if I could just change the Category Metabox to have the same Ajax autocomplete style as the Tags Metabox. All advice appreciated! | You can change the category metabox.
You can create custom metabox as per your need which contains all categories in proper layout.
Also you can search for plugins, say HTML5 category selector plugin < | stackexchange-wordpress | {

Convert all dates in field to Unix time, except those already in Unix time
I have a meta field that is mixed with MM/dd/yy hh:mm dates and Unix timestamp dates. How do I convert all of the MM/dd/yy hh:mm dates in the db to Unix? I have only limited PHP and SQL knowledge so be gentle. Thanks! | **strtotime** is php function that can be used for this purpose. **strtotime** — Parse about any English textual datetime description into a Unix timestamp

Loading shortcode stylesheet only when shortcode is in text widget
I would like to load shortcode stylesheet only when it will be put in text widget. Please help somebody. | I think you should be able to register your stylesheet with `wp_register_style()`, then load the stylesheet via `wp_enqueue_style()` from within the shortcode's function, so it only loads when the shortcode is executed.
For a rundown on how this will work here's a good article. It refers to scripts, but I believe the same is true for styles: <

What does the term "bundled-theme" mean?
I have occasionally heard the term "bundled-theme". I know what a WordPress theme is, but I don't know what a "bundled-theme" is. I came across that term recently when reviewing the WordPress documentation:
> "...For core (and bundled themes), this is always WordPress."(< | The term bundled theme is simply just a name/term used for the default (twenty-something) themes shipped with wordpress.

Create a custom URL for blog archive
I'm playing around with a test site and I've set up a static page as home page.
Now I want to make a menu item called `Blog` \- with url `example.com/blog/` \- where I'll list the latest articles. I made a custom page template and changed the `WP_Query` so that it queries a list of 10 latest posts. I then created a page and set the permalink to `example.com/blog/`.
For the permalinks, I'm using a custom structure `/blog/%postname%/` so that my blog posts are like `example.com/blog/post-name`.
The issue: I would also want that the monthly archive page and the category list page also use that custom page I made instead of their respective template files.
Or another solution I was thinking about is to get the normal archive page to work without using the custom page pointing to `example.com/blog`.
I'm kinda confused about how to implement the solution. | When you set up a static page as home page, you can set up also a page for the blog archive. If you do that, you don't need to alter the WP_Query in the blog page template, you only need to work with The loop like in a archive template file. When the page for the blog archive is requested, Wordpress will make the correct query for the blog archive.
To make the monthly/category archive use a different template file than the standard, you can use the template_include filter and the functions is_category() and is_date():
add_filter( 'template_include', 'inlcude_archive_page_template' );
function inlcude_archive_page_template( $template ) {
if ( is_category() || is_date() ) {
$new_template = locate_template( array( 'the-archive-page-template.php' ) );
if ( '' != $new_template ) {
return $new_template ;
}

value of metadata is null wrong use of if statement
I'm using the WP-Ratings plugin which uses the Wordpress built in custom fields to save values of ratings. The name of the custom field is `ratings_score`. I want to ask if each post has a specific rating. What I'm doing is inside the loop doing following:
<?php $rating = get_post_meta($post->ID, 'ratings_score', false); ?>
<?php if ( $rating == 2 ) ) { ?>
<script>
console.log("test");
</script>
<?php } ?>
But it does not work. Am I doing it wrong? I also tried to ask `if ( $rating == '2' )` but thats the same issue. There are definately posts which have `2` as value of `ratings_score` | Try:
$rating = get_post_meta($post->ID, 'ratings_score', false);
var_dump($rating);
You will notice that you get an `array`, even if your `ratings_score` is `2`. To wit:
array(1) {
[0]=>
string(1) "2"
}
That will never equal `2` so your condition will never work.
The third parameter of `get_post_meta()` if set to `true` will collapse that array to a scalar, and that will work.
$rating = get_post_meta($post->ID, 'ratings_score', true);
var_dump($rating);
Note that if your post has multiple `ratings_scores` you will only get one of them and it may not be the one you want.
To make this work with multiple `ratings_score` entries use:
$rating = get_post_meta($post->ID, 'ratings_score', false);
if (in_array(2,$rating)) {
echo 'found it';

How to customize custom taxonomy url?

How to know which wordpress plugin is exporting site information to plugin author?
Is there any plugin or method to know outgoing data? Nowadays every 5th plugin use to fetch data from sites. And I noticed that plugin authors are very enjoying this function. But as plugin users I'm liking it sometimes.
So far I've been digging into plugin files to remove their codes. But its not possible to do after every plugin update.
I think this features is facilitated by wordpress own functions. Is there any method to turn it off?
**Edit:**
For example Yoast seo plugin uses this file to fetch information about users. He even gets contents from database queries. Isn't it too much? The same way any plugin can get passwords too. | The functionality of making network requests for getting and sending data is abstracted into HTTP API in WordPress. As long as plugins do use related functions (and not make requests directly via raw PHP) you have degree of control over the behavior.
The easiest way is probably to only whitelist hosts you need/trust and leave rest blocked.
define( 'WP_HTTP_BLOCK_EXTERNAL', true );
define( 'WP_ACCESSIBLE_HOSTS', 'api.wordpress.org,*.github.com' );

A question about add_action()
I was following this ( < ) tut on codex. The part where a class is created and is called in add_action. No argument was passed to `emailer::send` ? Why? It was required in the function definition. | The `emailer::send` is the function callback for a `publish_post` action hook. This action hook accepts only one parameter which is the post ID and it is passed by Wordpress.
When you define an action hook, you set what parameters are passed to the callback functions. For example:
$arg_1 = "The aregument value";
do_action( 'my_custom_action', $arg_1 );
Every time you hook into `my_custom_action`, the `$arg_1` value is passed to the function callback automatically.
add_action( 'my_custom_action', 'my_custom_action_callback' );
function my_custom_action_callback( $arg_1 ) {
//Do whatever
}
In the example you are talking about, the `publish_post` action hook is is used. This action hook accept one argument, the post ID, and this argumente is passed to `emailer:send` automatically by Wordpress. | stackexchange-wordpress | {

unregister_sidebar() in stand-alone theme not working
With this StackOverflow Q&A I can't make the `unregister_sidebar()` work for me.
### Scenario
I have developed a theme using a sidebar area, where I've used a Widget. But I don't want the 'Editor' to get access to this Sidebar Widgetized Area in Admin area. So I want to do a tweak in my theme's `functions.php`, where I previously declared `register_sidebar()` somewhere to register the sidebar.
I understood that, setting a less priority will trigger the unregister function more earlier, so I tried with:
function site_unregister_sidebar() {
if ( is_admin() && current_user_can('editor') ) {
unregister_sidebar( 'my_custom_widget_area' );
}
}
add_action('widgets_init', 'site_unregister_sidebar', 1);
But nothing is happening.
* What actually I'm doing wrong?
* Is there any other way I can achieve this? | Thanks to Milo and G.M. for pointing to the master key, as G.M. said:
> _you have to use a lower priority than one register_sidebar runs, but lower priority means higher number._
So the final code that is working:
function site_unregister_sidebar() {
if ( is_admin() && current_user_can('editor') ) {
unregister_sidebar( 'my_custom_widget_area' );
}
}
add_action('widgets_init', 'site_unregister_sidebar', 20);
Because I set my sidebar with priority of 10 with the **same hook** \- `widgets_init`.
function theme_widgets_init() {
register_sidebar( array (
'name' => 'Custom Widget Area',
'id' => 'my_custom_widget_area'
) );
}
add_action( 'widgets_init', 'theme_widgets_init', 10 ); | stackexchange-wordpress | {

Sorting get_post_ancestors array
I have written this code for my breadcrumbs (i'll give only the part that I have problem with):
} elseif (is_page()) {
if($post->post_parent){
$anc = get_post_ancestors( $post->ID );

$output = '<li><a href="'.get_permalink($ancestor).'" title="'.get_the_title($ancestor).'">'.get_the_title($ancestor).'</a></li><li><i class="fa fa-angle-right"></i></li>';
echo $output;
}
So for a page I'm getting the array of ancestors and it works fine if I have single ancestor. When I have two of them or more then (by default as the codex states):
`The direct parent is returned as the first value in the array. The highest level ancestor is returned as the last value in the array.`
And that echoes out
`HOME > PARENT 2 > PARENT 1 > PAGE TITLE`

I have been looking through the docs but there doesn't seem to be a way to get permalink of the post, without the page number. Can anyone help? | I don't think your code works as expected because you are not printing the URL of the post.

LogOut button only if logged in in front end menu widget
I would like to add a "LogOut" button at the end of my sidemenu - but of course only, if someone is logged in. I also want to have it in two languages using qtranslate.
At the moment I have created a new Menu Item "Log Out" with a link to `/wp-login.php?action=logout` which works, but always shows up of course.
Is there a way to put something like this in the function? Any help - or just a hint would be very nice! :) | To add a menu item to the end of a nav menu you can use the `wp_nav_menu_items` hook. Combine that with `is_user_logged_in()` and you ought to have it.

return $items .= 'your login link';

get_terms Parent Tags

ACF checkbox array is returning numbers, not labels

The problem is that `$label` is returning numbers, not labels, so that the page is displaying `0`, `1`, etc. depending on which order it is in the array.
I'm not sure what I'm doing wrong here, or how to troubleshoot it. | ACF is actually doing what it should - storing a numerical array of selected values.

Taxonomy page shows category in title

phpMyAdmin displays error when importing database
I'm migrating a WordPress for a friend to a different server. I have already backed up all files and was given a copy of the database by the old server admin. The problem is that when I try and import the database using phpMyAdmin, I get this error message:
`SQL query: -- -- Database: ``wordpress_6`` -- CREATE DATABASE ``wordpress_6`` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; MySQL said: Documentation #1044 - Access denied for user 'prvtres9'@'localhost' to database 'wordpress_6`
I'm not sure what would initiate this error message, but the tiny amount of information I found out in several hours of frustration eludes that it could be in the way the database was copied, therefore putting me in a helpless position, but I don't want to approach the old server admin just to be wrong about this | If you have already created the database that you wish to import into and you have selected that database in PHPMyAdmin, but the import file is trying to create a new database, then you will see this error message.

Now try the import again and it should import that data into your selected database rather than trying to create a new one. | stackexchange-wordpress | {

Multisite and plugins options
I need more information about `get_site_option()`, `update_site_option()` and `add_site_option()`. In codex they say it's the same as single install except that in multisite, it returns the network-wide option.
Ok but I get confused on the this point : does it mean once network-wide option is set this option is the same in all sites? Or is it overriden per each site?
I mean if I do this :
update_site_option('option_group', 'default_options());// default_options() returns an array of default options
Where will it save datas? And will each site get its own values for options after?
It's quite unclear for me any hint will be cool. | Back when Multisite first appeared, there were multiple _blogs_ in a single _site_. The `*_site_option` functions are from that older Multisite era.
Now in current Multisite you have multiple _sites_ in a _network_ , so the meaning of "site" has made a confusing change.
In the context of these functions, think of them as _network_ functions and it may make more sense. They create and update options which are not associated to a particular site in your network, but are global to the whole network.
If you want unique, per-site options, use the regular `add_option`, `update_option`, and `get_option`. | stackexchange-wordpress | {

Unicode characters are saved in a funny way in the DB

How to display summary content from a Page (Not a Post) on another page

Display Image Upload from Contact Form 7 on Redirect Page

Thanks in advance! | I solved this problem using the Contact Form DB plugin.
1. I used their HTML shortcode [cfdb-html] to call the img url saved to the wordpress database

Extending WP_List_Table seems getting wrong with $this->get_columns() - what's wrong?
I'm trying to implement an Admin Table for a view page of a plugin of mine by following the following tutorial:
* **Create Native Admin Tables In WordPress The Right Way**
by _Jeremy Desvaux de Marigny_
SmashingMagazine.com
Here's how I extended the `WP_List_Table` class for my plugin. (Code at Pastebin)
The problem is: it's not showing any Column or Row, only the Table Top and Bottom. I did `var_dump()` steps, and found that in **Line 149** the `var_dump($columns);` is showing empty.

/* -- Register the Columns -- */
$columns = $this->get_columns();

Get section of input passed to the sanitize_callback
How can I find out what section each input is in when viewing the `$input` array passed to the sanitize_callback function defined in `register_setting()`?
I suppose one option is to include the section as part of the field name and can then extract it. E.g. `name="section^field"` and then in the sanitize_callback:
foreach($input as $name => $val) {
$parts = explode('^', $name);
$section = $parts[0];
$field = $parts[1];
// do more stuff here
}
But this feels a little hacky. Is there a better way? | Unfortunately if you look at the source the only thing that happens there is:
add_filter( "sanitize_option_{$option_name}", $sanitize_callback );
There is no opportunity to pass along or retrieve any extra information.
On a larger scale I would say if you need section-specific sanitize then use section-specific callbacks. Even if considerable parts are shared with class based code it should be easy enough to neatly organize. | stackexchange-wordpress | {

Wordpress Update Plugin Hook/Action? Since 3.9
I've researched this a few times, yet my searching does not reveal much except custom code which may or may not be good WordPress practice.
As of the latest releases (WordPress 3.9 "Smith"), **has a hook been added to the plugin update process?** I'm asking because its a very basic need, yet I do not see it added to the codex (yet). If not, what is the common and best practice developers employ?
EDIT: Just to clarify, I'm not talking about activation, but about updating, that way, if there are changes in database or otherwise it can be addressed. | I don't think an action has been added. You can look at version details for any version and see any new actions added.
The WordPress Way to run code on plugin update is what is described here:
> The proper way to handle an upgrade path is to only run an upgrade procedure when you need to. Ideally, you would store a “version” in your plugin’s database option, and then a version in the code. If they do not match, you would fire your upgrade procedure, and then set the database option to equal the version in the code. This is how many plugins handle upgrades, and this is how core works as well.
and with code example here:
function myplugin_update_db_check() {
global $jal_db_version;
if (get_site_option( 'jal_db_version' ) != $jal_db_version) {
jal_install();
}
}

How is the `get_sidebar` function meant to be used to call a 2nd sidebar?
What's the proper way to call a second sidebar in the main home of my blog? And I mean 2 sidebars at the same time....
I might edit the question when I get further info, but now I'm feeling completely lost. | All that `get_sidebar()` really does is load a file. Which file you load depends on how you call the function. `get_sidebar()` will load `sidebar.php` from the theme directory. `get_sidebar('two');` will load `sidebar-two.php` from the theme directory. "Theme directory" means the same folder as should have `style.css`. That is all there is to using the function.
Beyond that, I don't know what this question means. | stackexchange-wordpress | {

query posts only works on the first page

Alternative to mysql_real_escape_string
I have a WordPress plugin that at one point I need to see if a certain title exists in the database. For 2 years, this code worked fine:
$myposttitle= $wpdb->get_results(
"select post_title from $wpdb->posts
where post_title like '%". mysql_real_escape_string($myTitle) . "%'"
);
However, with php 5.5. and WP 3.9.1, this causes an error because the function `mysql_real_escape_string` is deprecated.
Any ideas on what other function will properly escape the contents of `$myTitle` now that I can't use `mysql_real_escape_string` anymore?
Thanks | When working with database in WordPress you should never use the low lever `mysql_*` or `mysqli_*` functions.
Always use `$wpdb` methods, in your case you should use `prepare()`:
$query = $wpdb->prepare(
"SELECT post_title from $wpdb->posts
WHERE post_title LIKE %s",
"%" . $myTitle . "%"
);
Moreover, once you are getting a single column, you have easier life using `get_col` instead of `get_results`:

How to import XML to Wordpress as post and custom fields?
I need to import content (daily) from a xml file into wordpress. I am not looking for a specific answer, and I don't expect someone to write the whole code here, I just need some guidance on how to accomplish it.
I plant to:
1. Write php script to load XML file with simplexml_load_file()
2. Read the file with SimpleXMLElement()
3. Put everything in a loop and use wp_insert_posts to create each post
4. I am going to use ACF for custom fields, not sure if ACF has function to do that programmatically.
5. Run everything with a cron job

Theme: Twenty Thirteen Mobile Sliding Menu Doesn't Bump Content Down
I have created a child theme for Twenty-Thirteen and somewhere while editing it I broke the mobile menu slider as it no longer pushes the content down and instead displays behind the content. I've changed the CSS in someway to cause this issue but I cannot find what has caused it. I am hoping that the cause will be more apparent to someone more familiar with CSS than I.
To view this issue you must resize your browser to width of less than 700px or so and click the menu button revealing the slider menu and the content overlap issue. Note how the H1 tag "Quad Cities, Chicago, Des Moines Photographer Brian Barkley" is over top menu.

Activated plugin is stored as an object, rather than as a path
This seems like a very unusual behavior: Usually, when activating a plugin, a path to the plugin's main file (or bootstrap) is stored in the database under `options.active_plugins`. However, something in the following code is causing Wordpress to store the object itself, rather than a path to it, in the database.
Here is the plugin's bootstrap file (`bootstrap.php`):
/**
* Plugin metadata
*/
require_once( plugin_dir_path( __FILE__ ) . 'MyPlugin.php' );
$plugin = new MyPlugin();
$plugin->init();
After activation, the `active_plugins` option entry will look like this (retrieved using `get_option( 'active_plugins' )`:
Array {
[0] => (object) MyPlugin
}
When the expected result would be:
Array {
[0] => bootstrap.php
} | You should just not add code outside of actions (callbacks attached to hooks and filters). Else your variables might conflict with global variables. The default/first action for a plugin bootstrap would be (depending on the type of plugin): `plugins_loaded` or `muplugins_loaded`.
Attach hooks from there on to `wp_loaded` if you want stuff to run on `init` (but make it multisite save - `init` has other drawbacks as well). | stackexchange-wordpress | {

Replace all media (images)

Combining wp_current_user() and a variable
I want to match a custom field in a user's profile to a particular post the user might be on. So I've got the custom fields for user profiles setup, and they're all numeric. Then, if I'm on a post page, I want to check if that post's ID matches the custom field in their profile. Something like this, where the custom field in the user's profile is `badge-id-2000`
$current_user = wp_get_current_user();
$badge_ID = $post->ID;
if ($badge_ID == $current_user->badge-id-$badge_ID) {
return true;
}
Apparently on line 3 there where I'm using `badge-id-$badge_ID`, the variable doesn't work in that scenario. Is there some other way of doing this or getting the variable to work there? | What you have is mostly just PHP errors.
First, dashes are not valid characters in variable names, so are going to have trouble with this-- `badge-id-$badge_ID`\-- no matter what. You should be using underscores instead.
Second, you need to construct the entire object variable string beforehand, rather than try to construct it as you are using it.
For example...
$badge_ID = $post->ID;
$badge_str = "badge_id_{$badge_ID}";
if ($badge_ID == $current_user->$badge_str) {
echo 'Yay';
}
Third, I am pretty sure you data structure is more complicated than it needs to be. You have to have an odd construction for `badge_id_*` like `$current_user->badge_id_123 = 123;` with numerous different badge ID object variable names, when you could just have `$current_user->badge_id = 123`. If you did that, you could simply this to:

Why is the $old_instance needed for the widget update function?

* The newly calculated value of $instance should be returned.
* If "false" is returned, the instance won't be saved/updated.

So a very simple update code could look like this:
function update( $new_instance, $old_instance )
{
return array_merge( $old_instance, $new_instance );

Copy a file from a plugin into my theme directory
I coded a wordpress plugin using php's 'copy()' to copy a file from my plugin directory to my theme directory, but it's not working:
<?
function file_replace() {
$plugin_dir = plugin_dir_path( __FILE__ ) . '/library/front-page.php';
$theme_dir = get_stylesheet_directory() . 'front-page.php';
copy($plugin_dir, $theme_dir);
if (!copy($plugin_dir, $theme_dir)) {
echo "failed to copy $plugin_dir to $theme_dir...\n";
}
}
add_action( 'wp_head', 'file_replace' );
I thought maybe I should use `! $wp_filesystem->put_contents()` but I'm not exactly sure how to do that or if that would even be the right way to go. Any ideas on the best way to copy a file from a plugin to a theme directory?
Thanks | To answer your question, you have specified the paths incorrectly: `plugin_dir_path( __FILE__ )` already has a trailing slash at the end (having two trailing slashes should not be a problem, but safer is to have one) and `get_stylesheet_directory()` comes with no trailing slash at the end, so you have to add one before adding the filename. Your final code should be like this:
<?php
function file_replace() {
$plugin_dir = plugin_dir_path( __FILE__ ) . 'library/front-page.php';
$theme_dir = get_stylesheet_directory() . '/front-page.php';
if (!copy($plugin_dir, $theme_dir)) {

Changing permalinks and redirecting urls
I'm moving a client from Tumblr > WordPress. I can't figure out how to make the new permalinks work.
Two issues:
1. The current Tumblr urls look like this: < But when I import the posts to WP, it chops off the end of the urls. I end up with just: < **So, question 1:** Can I append a slug to the end of that number? I've found a handy script that will rewrite the urls for me, removing the numbers and leaving me just with /post-name. But I'd like to keep that number in there.
2. The url of the site is changing from < to just < **So, question 2:** Can I accomplish a proper redirect with a 301 directive in my htaccess file? | For the first question, you would need a rewrite plugin, as WordPress wouldn't be able to handle the numbers in that string otherwise (it would see every site as a 404 Not Found), as slugs can't contain slashes of any kind.
Ideally I think your best approach would be to set the post names without the digits (to make them human readable), and then use a plugin such as the Redirection plugin to forward requests to the old URL (with numbers) to the new one (you can set up a regex redirection here, so a simple rule to strip out just the numbers, or you can do one redirection per URL if you want to be extremely thorough).
As for the permanent 301 redirect for removing the blog sub domain, the plugin mentioned above can handle this as well. Manually editing the .htaccess file isn't advised as plugins or themes may issue a hard refresh which overwrites the content of that file. | stackexchange-wordpress | {

How to update plugins with database updates if I use svn
I have my own SVN repository that has everything checked in from root of the htdocs directory.
The repository includes (I do have some ignores set):
* Wordpress Core
* Plugins
* Themes
My process is:
* update my repository on a development site first to test
* commit the changes
* svn up the production site
My question is:
* If a plugin installed has database updates attached to the newer version how are those updates applied in my production instance?
I do know that Wordpress core has checks in place to see if the db is updated to the newest version, but I'm unable to find the same information out regarding plugins. | This will not be a problem.
WordPress doesn't provide plugins with an explicit update hook for this reason:
> If a plugin is manually updated then this upgrade hook won't fire. The best way to manage database upgrades is to do it the same way as WordPress does it. Store an option containing your plugin's database version and check it on the admin_init hook and run the upgrade routine when it doesn't match the version in your plugin. Many popular plugins use this method. It's definitely the most fool-proof.
[From ticket #19681]
So, each plugin has to do its own check to see if its database version is up to date. Plugins will generally run this check each time WordPress runs, or each time the admin panel is accessed, and update their database if needed. So if the plugin has database updates, they will probably be applied the first time someone visits the site after you run `svn up`. (Or, for some plugins, until someone visits the administration screens.) | stackexchange-wordpress | {

Modify Search Query if original Query gave no results

Something like this:
global $wp_query;
$total_results = $wp_query->found_posts;
if ( $total_results == 0 ) {
// Create a new query with the terms 'Find Us'
}
// Display results (either those for the 'Opening times' query or for the 'Find Us' one if the former didn't return any result)

Redeclare a function in a child theme
I want to redeclare a function that I inherited from the parent theme.
When I do it in functions.php, I get a fatal error that redeclaration is not possible.
I did a workaround: creating a modified function name and copying all the template files, index.php etc. into the child theme's directory and rewriting the function calls. So now the new function is called.
This works but ignores any updates that the parent theme would have.
Is there a better solution to this? | Redeclaring a function in a child theme only works when the parent themes' function is wrapped in a
if( !function_exists( 'function_name' )):
condition. Then you can simply just copy the complete function to the child theme and do whatever modifications you need to do.
If the parent themes' functions aren't wrapped in that `if` conditional statement, and if no filters or hooks are supplied in the function, it will be best to copy the function to your child theme, rename that function, do your modifications and then update your template files accordingly to reflect the new function. | stackexchange-wordpress | {

How can I safely use $_SERVER['REQUEST_URI'] to avoid XSS?
