Hacking TinyMCE for better usability (shortcodes and html)
I'm looking for some theme or plugin examples that showcase ways in which to enhance the usability of editing shortcodes and/or custom html objects that have been inserted into the editor.
I know that its possible to apply runtime styles to elements (nextpage and image rollovers are a couple examples) and I'm looking for some examples of scripts that seek to extend this to other elements (custom classed divs for example).
I've never seen an example of shortcode editing that went beyond the basic bracket+properties+content.
Ideally, I'd like to see an example where someone has abstracted shortcodes into their html equivalent, with rollover and right click events to modify element attrributes.
Just looking for any examples of work in this field. | Have a look at my Gridster Plugin, it replaces every shortcode `[gridster id="" title=""]` with a visual replacement, like you know from the [gallery]-Shortcode.
!enter image description here
To change parameters of the current shortcode, you're able to click a button and a tinyMCE modal will let you change anything within a user-friendly GUI.
!enter image description here
The functions are based on the the way, the gallery-shortcode-replacement works.
If this points into the right direction, I could get in more detail if you want. | stackexchange-wordpress | {

How can I show/hide HTML elements if the page is_front_page
For example if its `'is_front_page'` I want to hide a div. If its not the `'is_front_page'` i want to show the div. How can i achieve this?
I am not sure on how I can achieve this. Any assistance would be great. Thanks | This is really not enough information, so I have to guess.
### A) The _div_ is part of the content
Use PHP, check for front-page, and if not, handle the div:
<?php if (! is_front_page()) : ?>
<div />
<?php endif; ?>
### B) The _div_ is located somewhere else on the page
Give the div an ID and use jQuery:
<?php if (! is_front_page()) : ?>
<script>
jQuery(function ($) {
$('#DIV-ID-HERE').remove();
});
</script>
<?php endif; ?>
**// EDIT**
Of course, method A should be preferred! I'd suggest to include the above code where the div is generated. | stackexchange-wordpress | {

hrecipe microformat tag to "featured image"
I have a website made with wordpress which includes recipes. Now I would like to add the "photo" `hrecipe` Microformat tag in order to have a thumbnail on Google searches (hrecipe photo tag)
My recipes pictures come from the featured image section. How can I now add `itemprop="photo"` to the `<img>` tag?
For example:
<img itemprop="photo" src="apple-pie.jpg" />

<div class="post-thumb">
<?php if( !is_singular() ) { ?>
<a title="<?php printf(__('Permanent Link to %s', 'zilla'), get_the_title()); ?>" href="<?php the_permalink(); ?>"><?php the_post_thumbnail('blog-large'); ?></a>
<?php } else {
the_post_thumbnail('blog-large');
} ?>
</div> | Use the filter `post_thumbnail_html`. The callback takes 5 parameters, the first (`$html`) is the one that's returned and that we modify, and the others can be helpful to build the modification.
add_filter( 'post_thumbnail_html', 'add_tag_to_featured_wpse_95469', 10, 5 );
function add_tag_to_featured_wpse_95469( $html, $post_id, $post_thumbnail_id, $size, $attr )
{
$modify = str_replace( '<img', '<img itemprop="photo"', $html );
return $modify;

Wordpress Flyout Menus
I have a bit of a complicated menu structure that I am trying to figure out the best way to do this.
**I have a top nav** that has 4 SECTIONS. Each Section has upto 2 levels deep.
Also, **I have a SUB Nav** that is based on what section you are in and displays as a drill down showing what page you are own.
For example, say I click on a second level TOP NAV - I would then go to that SUBPAGE showing the SUB nav having that section open and selected.
I hope I explained that correctly...
Thanks.
My Question is: What is the best way to do this. I've researched some plugins but I can't seem to find the right one.

SEO smart plugin not working for words ending with ä, ö, å
Custom keywords don't get linked if words end with this letters : ä, ö, å
It works if those letters are inbetween. any idea how to fix this?
Custom Keywords :
> 1. meäts, www.google.com - works
> 2. tillhört, www.rediff.com - works
> 3. Elektrobitissä, www.git.com - does not work
> 4. tillhrtö, www.rediff.com - does not work
>
So out of the above keywords, 1 and 2 works. 3 and 4 does not work. If word ends with those special letters, word is not linked otherwise if letter appears in any position except last, it works.
< | The author is using string functions for single-byte encodings:
$url = substr($line, $lastDelimiterPos + 1 );
$keywords = substr($line, 0, $lastDelimiterPos);
But in WordPress everything is encoded in UTF-8, a multi-byte encoding. So each time you have a character in your keywords that needs more than one byte, something gets lost.

unused post IDs
Recently I installed plugin called Delete-Revision and noticed that every post has registered few post IDs. I usually use save drafts and update post a few times when I write a post.

If you check the plugin directory you'll find several that will clean up old revisions, such as this one.

Schedule future post to custom post status instead of publish?
I've been doing some research into custom post statuses and scheduling posts and I had a question: I was wondering if it were possible to schedule a post to got from `future` to a custom post status instead of `publish`? Main reason I'm asking is that I have a custom post type called `stream` and I've created a custom publish meta box that allows a user to select 2 post statuses: `online` and `offline`. I'm trying to make it so that if I set a future date, the stream post will transition to `online` instead of `publish` as it normally would.
My train of thought would be to hijack via filter the post status to automatically transition to `online` whenever WordPress tries to set it to `publish`. Would that be a viable option? | Here is one idea:
You could try to use the `future_to_publish` action to change the post status:
add_action('future_to_publish', 'set_status_online_wpse_95701');
function set_status_online_wpse_95701( $post ) {
if ( $post && $post->post_type==="stream"){
$post->post_status="online"; // change the post_status

home_url(); showing current page instead of site address
Does anyone have an idea why my home_url() function gets the URL of the current page instead of the site address? (The site runs locally using MAMP.) | Since you didn't post actual code in your question, I can only speculate. However, a common problem is that, when calling `home_url()`, it is not _echoed_. The value of the function is _returned_ , rather than _echoed_, so it must be explicitly echoed by the code.
I'm guessing you have something like this:
<a href="<?php home_url(); ?>">Home</a>
Which renders like so:
<a href="">Home</a>
...and would explain why the linked URL is the current page, rather than the expected URL for the site front page.

Create Table Failed Column Date DateType

Get date of last update outside of loop
I'm trying to figure out how to display the date that a post was last updated outside of the loop. I'm able to display the published date using `get_the_time()` but there doesn't seem to be a "loopless" function to get the date of the last update.
Does anyone know hot to do this? | It is unclear if you are looking for the last updated post or for the last updated date for some particular post. The answer by @PatJ assumes the former. To do the latter:
$qry = new WP_Query(array('p'=>1));
var_dump($qry->posts[0]->post_modified);
Or...
$date = $wpdb->get_var("SELECT post_modified FROM {$wpdb->posts} WHERE ID = 1");

How to make wp cron job not fire immediately?
I'm scheduling a job in wp cron:
add_action('my_cron_hook', 'my_cron_action');
wp_schedule_event( time(), 'interval1', 'my_cron_hook' );
function my_cron_action(){
//do something
}
The variable interval1 is set by the admin in another part of the code.
Also, there is a switch that lets the admin _enable_ or _disable_ the wp crop job.
**My problem is this:**
my_cron_action is executed as soon as it is scheduled
(this means, as soon as the admin enables the cron job from the backend).
**What i want to do is this:**
if we suppose that the time that the admin enabled the job is **T** ,
i want the job to be run at **T+interval1** for the first time, and _not at T_.
The next thing i want after this is done, is to create a button "Execute job now" that will run the job as soon as it's clicked. | As described in wp_schedule_event first parameter is `$timestamp` \- the first time that you want the event to occur. So just add interval to $timestamp. I think it should be like
wp_schedule_event( time() + $delay, 'interval1', 'my_cron_hook' );
And set `$delay` as miliseconds before hook starts. | stackexchange-wordpress | {

Remove class that has been added by parent theme
My parent theme generates the following class in `body`: `style-cupcake`. I don't want that. The best way to get rid of this is by adding my own functions in a `functions.php` file in my child theme, right?

<?php
function my_body_class( $wp_classes, $extra_classes )

// Add the extra classes back untouched
return array_merge( $wp_classes, (array) $extra_classes );
}
add_filter( 'body_class', 'my_body_class', 10, 2 );
?>
Any idea? | If you want to apply a filter to the same content another function has filtered, change the _priority_ argument (which should have been named _execution_order_) to a higher number.
So …
add_filter( 'body_class', 'my_body_class', 11, 2 );
… will make sure `my_body_class()` will be called after `another_body_class()` that has been registered with 10:
add_filter( 'body_class', 'another_body_class', 10, 2 );
Also note the _priority_ argument will be used as an array key. It doesn’t have to be a number, just a valid key.

Implement location at wordpress post via custom taxonomies?

for example: Orlando + Florida + United States Monroeville + Pennsylvania + United States Noyabrsk + Yamalo-Nenets Autonomous Okrug + Russia
In the final implementation the user can choose post (or posts list) by choosing Country (and or) states & territories (and or) City.
One more thing for my example: if the user choosing Russia as Country he won't get the option for Florida as States&territories...
Can I implement it as custom hierarchical taxonomy (or 3 custom taxonomies)? | Yes implement it as a heirarchical taxonomy. Have your countries as the top level terms, then states, then cities. Your URL structure will naturally reflect this. I would advise against /city/state/country, as it is illogical and counter intuitive, and doesn't make for a good heirarchy ( so bad SEO too ).
On your frontend, taxonomy-location.php should be your template. I'd strongly advise against using 3 dropdown lists, as it's poor UI/UX and a pain to implement. Instead look at ecommerce sites and implement the drilldown list pattern of picking a country, then picking a state on the next page, then a city on the next, letting users look on a country wide level or a state wide level or a city depending on how specific they want it.

How do I remove unwanted pages like archive, search, etc.?
By default WordPress pushes out a whole array of pages I don’t want or need - archive, author, blog, monthly, recent posts, categories, comments, attachment, taxenomies, search, search results, and probably a few others I’ve missed.
Most of the time I’m building regular broshure websites with no need for anything except a few fairly static pages. How do I get rid of all the other pages? Is there a plugin that will do this? Do I have to set up a dozen redirects in the .htaccess? I’ve tried searching, but all I find is how to hide parts of a page, or customise the sitemap to hide from searches.

exit;
}

How can i insert these codes automatically into my header and footer files from my plugin.
many thanks | Actually including that code in your theme template files is the only surefire way to include those widgets in various themes. It's also the best to get them where you want them.
Alternatively, you could accomplish this using hooks, but that relies on your themes actually calling the hook, and in the proper location. The safest bets are the `get_header` and `get_footer` hooks, which are called just before fetching the footer.php and header.php files, respectively.
add_action( 'get_header', 'header_widgets' );
function header_widgets() {
if( is_front_page() ) {
get_sidebar( 'homepage' );
}
}
add_action( 'get_footer', 'footer_widgets' );
function footer_widgets() {
get_sidebar( 'footer1' );

display specific custom fields

unique identifier for the same pages in a multilanguage/site context
I've got always the same problem. If I program a multisite for multilanguage purposes, I cannot find a way to not change the page links in every language. I mean, suppose I've got a page named 'Activity' in the english version. Then got the Italian version, and the same page is called 'Attività'. If I've got a manually-setted link outside the menus, say:
get_page_by_title('Activity')
Then I've got to translate it in the IT theme:
get_page_by_title('Actività')
And so on for all the other languages.
So, is there a way to avoid having to check for all links in every language?
Thank you | I've found out that another answer could be to just use the is_page_template tag.
Since I'm preatty sure that the NAME of the php template file that needs custom css and/or js will be the same through all the languages (both using the multisite way or things like WPML), I can say
if(is_page_template('that-page.php')) do this..

Wordpress plugin for nicer looking slugs? Have multiple pages named the same but they get different slugs
This wordpress site I'm touching up has a page hierarchy which is responsible for the urls.
Basically the urls look like page1/subpage/subsubpage etc.
The problem is, this site is for a recurring competition and therefore the urls are like 2011/results 2012/results 2013/results
Which wordpress in turn makes 2011/results 2012/results-1 2013/results-2
Which doesn't look that great..
Is it possible to mod_rewrite or something to work around this? I understand the need in Wordpress for unique slugs but I really can't see why they enforce it even when it's impossible to get duplicate urls for different pages... | I use the Custom Permalinks plugin for Wordpress.

Query "Category A" + 1 post from "Category B" - how?
It's pretty easy to query posts from one category but what if I need also one single post from another category?
$query = new WP_Query( 'cat=4' );
I'm looking for something like this:
$query = new WP_Query( array( 'cat' => 4, 'post__in' => array( 20 ) ) );
But the above code will not return anything because there are not posts with an ID of 20 in category 4. I'm wondering if anyone has any idea how this could be done. | I don't see a way to do this with `WP_Query` alone. However...
function posts_where_add_post_wpse_96030($where) {

return $where." OR {$wpdb->posts}.ID = 1";
}
add_filter('posts_where','posts_where_add_post_wpse_96030');
$query = new WP_Query( 'cat=9' );
That will alter the query everywhere it runs so you will need to add conditions to the callback so that `$where` is only altered where you want it to be. For example...
function posts_where_add_post_wpse_96030($where) {
global $wpdb;
if (is_home()) {
$where .= " OR {$wpdb->posts}.ID = 1";
}
return $where;
}
Now the query will only be altered when it runs on a page where `is_home` is true. I don't know what conditions you need. You didn't include that in your question so you will have to work that out yourself. | stackexchange-wordpress | {

P3 Profiler and Yoast SEO plugin
I have profiled my blog with the P3 Plugin and it pointed out that Yoast SEO slows down the site a bit. I then found out that the biggest performance penalty is paid when you "force rewrite" the titles[1], which I am doing.
Now I do have quite an aggressive caching turned on with WP Super Cache. Does it still matter if I force-rewrite the titles then? Or in my case it doesn't change a thing since pages are pre-generated and served as static content?
[1] < | > Now I do have quite an aggressive caching turned on with WP Super Cache. Does it still matter if I force-rewrite the titles then? Or in my case it doesn't change a thing since pages are pre-generated and served as static content?
Yes it does matter because you are not serving cached content 100% of the time and you also have to think about the time and resources it takes to rebuild the cache.
You eliminate the need to force title rewrites by fixing your theme and replacing whatever is currently being used in the title tags with:
`<title><?php wp_title() ?></title>`

Filter everything from content except output of a shortcode
Is it possible to filter the output of either the content or excerpt so that I only get the the shortcode output and so that if a user enters more than the shortcode the rest of the content for that page would be stripped. | function shortcode_only_wpse_96114($content) {

How to centre menu items on horizontal nav bar? (e.g. make margins equal)
I'm currently working on building this site:

Include HTML template file in wp_mail
I'm using `wp_mail()` to send an HTML email. But there's quite a lot of HTML code in the email, so rather than including all the code in my `wp_mail()` function, is it possible to have the code in a separate template and just include this template in the function? Here is what I have:
<?php if ( isset( $_POST['submitted'] )) {
add_filter('wp_mail_content_type',create_function('', 'return "text/html"; '));
$emailTo = '[email protected]' ;
$subject = 'This is the subject';
$body = get_template_part( 'includes/my_email_template' );
$headers = 'From: My Name' . "\r\n";
wp_mail($emailTo, $subject, $body, $headers);
}?>
I'd like to be able to put all of my HTML code in 'my_email_template' but when I try this, no email is sent. Am I including the template incorrectly? Thanks in advance for any answers. | Per my comment to your question, I believe the problem is that `include`ing files, whether directly or using `get_template_part` isn't likely to give you a string to pass to `$body` and that is going to cause errors in the code, or at the very least unespected behavior.
I would avoid reading files into memory and just create a function that returns your `$body` content.
function get_email_body_wpse_96357() {
$body = '<p>Hi</p>';
return $body;
}
Then use `$body = get_email_body_wpse_96357();` as needed. An advantage of this method is that you can easily pass parameters to the function if you ever decide to do so. You could also use variables in an included file but it can be messy.
If you don't want to load that function all the time, then put it in a file by itself and include that file only when you need the function. | stackexchange-wordpress | {

Customize Search Results for Custom Post Type

switch ($type) {
case 'attorney':
case 'criminal':

Problem with is_tax in WP_Query loop
The code below is the 2nd of 4 loops in "page-balls.php". Everything else is working correctly.

<?php wp_reset_postdata() ; ?> | The codex on `is_tax`:

That is not the condition you want to check for.
Take a look at the `has_term` function and use it like so:

/* SHOW THE TENNIS BALL GRAPHIC */
} else {
/* SHOW THE PLACEHOLDER GRAPHIC */

Admin Posts List (edit.php) by post IDs
I'm writing a plugin that creates posts in bulk. I provide a way for the user to set certain parameters of the created posts beforehand.

Extend the wp_users table
I'd like to to extend the `wp_users` table in my WordPress' database.
Why? I want people to add more information about themselves when they sing up at my website.
I know how to extend it, but I'm afraid that when WordPress needs an update the `wp_users` table, i.e. the columns I added, will be deleted.
I there anyone here who has some experience with extending the `wp_users` table?
Will this table be updated when the WordPress version is updated? | **There are data loss risks to doing this!** If you do this you might lose any data stored this way when WP updates and "fixes" the table schema in a database upgrade.

* add_user_meta
* get_user_meta
* update_user_meta
There are also user taxonomies and terms, but meta is the best way to attach additional data to a user.
There are many tutorials explaining how to add additional fields to the user profile using User meta to store them, and it's how a lot of standard data is stored already, such as the positions of boxes on the dashboard when you drag them around, how many posts to show at once in the edit screen, or which popups you've clicked dismiss on | stackexchange-wordpress | {

Only list categories that contain posts of a specific custom post type
I have three custom post types set up, `articles`, `videos` and `photos`.
I am using standard categories for these post types, and sharing the categories across all post types.
I am trying to create a nav menu for each post type, listing the categories, that should follow the following structure:
* Photos
* Cat 1
* Cat 3
* Cat 5
* Videos
* Cat 2
* Cat 3
* Cat 5
* Articles
* Cat 1
* Cat 2
* Cat 4
Categories that do not contain the custom post type should be hidden.
`get_categories()` with `hide_empty` set to `1` is obviously close, but it doesn't allow you to specify a post type. | Put the following in your `functions.php`:
function wp_list_categories_for_post_type($post_type, $args = '') {
$exclude = array();
// Check ALL categories for posts of given post type
foreach (get_categories() as $category) {
$posts = get_posts(array('post_type' => $post_type, 'category' => $category->cat_ID));
// If no posts found, ...
if (empty($posts))
// ...add category to exclude list
$exclude[] = $category->cat_ID;
}
// Set up args
if (! empty($exclude)) {
$args .= ('' === $args) ? '' : '&';
$args .= 'exclude='.implode(',', $exclude);
}
// List categories
wp_list_categories($args);
}
Now you can call `wp_list_categories_for_post_type('photos');` or `wp_list_categories_for_post_type('videos', 'order=DESC&title_li=Cats');` and the like. | stackexchange-wordpress | {

<i class="icon-quote-left icon-2x pull-left icon-muted"></i>

Changing Woocommerce Product Description

Remove comma from last item output from loop
(or add comma to all items but the last one...)
Most of the information I have found relates to using a counter within a `foreach` loop. In this particular situation I am using Advanced Custom Fields and I am within a standard loop, not a `foreach` loop.
I need to add a comma to the end of each item except the last.
<?php while( has_sub_field('images') ): ?>
<?php $image = wp_get_attachment_image_src(get_sub_field('image'), 'wsn_canvas'); ?>
<?php echo $image[0]; ?>
//echo comma here
<?php endwhile; ?> | There is nothing 'standard' about a `while` loop and in this case it makes things harder, since you need a total count of all the items in loop in order to know if you are on the last item or not. It is not obvious how to get that total count with a function like `has_sub_field` but there is a quick way to do this that I use fairly often to build character separated strings when I don't know how many items will be in the final result.
$attach = array();
while( has_sub_field('images') ):
$image = wp_get_attachment_image_src(get_sub_field('image'), 'wsn_canvas');
$attach[] = $image[0];
endwhile;

Should I remove install.php and install-helper.php?
Is keeping `wp-admin/install.php` and `wp-admin/install-helper.php` a security leak on the newer versions of wordpress? By default file permission on those files are 644.
If there is any leak, what kind of please? | No, there is no security risk. Both files do sanity checks before anything happens.
If WordPress is already installed:
* `install-helper.php` returns just a blank page.
* `install.php` says WordPress is installed and you should log in: !enter image description here
You can forbid access to both files with a simple rule in your .htaccess above the permalink rules:

creating wp query with posts with specific category
Im running a specific wp_query to show the thumbnails in a slider of a specific category.

This doesnt appear to be working, am i missing array at the beginning somewhere

the above seemed to crash it.
Any advice would be great. | Use either:

**Please note** that `category_name` actually is the category **slug** (which is for one-word names originally the same). It is not the actual name (maybe having spaces, special characters etc. in it), though. In your case, where you just want to specifiy a certain category, you can do this either by means of the ID (`cat=42`) or the slug (`category_name=events`).
If you really want/have to use the name, you have to use `get_cat_ID('Category Name')`, for instance like so:
$the_query = new WP_Query(array(
'posts_per_page' => 2,

wpdb query problem to access previous 3 days posts
I am trying to get all published posts titles by author id 2 most recent by post date for the last days. Here is my query:
"SELECT post_title FROM $wpdb->posts WHERE post_status = 'publish' AND post_author = 2 ORDER BY post_date DESC LIMIT 3 "
This displays most recent 3 posts instead posts of last 3 days. How to get that query right? | You are asking for the last three posts ordered by post date, not for the posts from the last three days-- `ORDER BY post_date DESC LIMIT 3`. `post_date` has a time component to it. It is not just marked with a date. Even so, that `LIMIT` would restrict the query to last three in the list, not all of the posts that are more recent than three days.
What you need is something like this:
SELECT post_title
FROM $wpdb->posts
WHERE post_status = 'publish'
AND post_author = 2
AND post_date > DATE_SUB(CURDATE(), INTERVAL 3 day)
ORDER BY post_date DESC

Wp-admin Custom User Management
I am working on a plugin for which I will have to develop a backend page similar to the built-in "Users" one, in the sense that it will be basically do the same things: list the existing users ( using the `WP_List_Table` class ), edit / remove, and add new ones as well. The only difference is that it will have a couple of additional fields, as well as some other custom functionality.
My question is: should I be working with the already existing WP functions for handling users: `wp_insert_user`, `wp_update_user`, `wp_remove_user` or is it recommended to make direct calls to the database? Although this may be a little more complicated, I was wondering if it's the way recommended / only way to go. | Always use the existing functions, if those functions do what you need. That way, your code has the best chance of staying functional as the Core changes. If you make direct queries to the database then you have to keep track of changes to the database and alter your code accordingly.
Using Core functions also means that hooks have the best chance of working where they are intended to work. If you make direct queries to the database you bypass those hooks, unless you make a special effort to support them. Again, you will have to monitor changes and update your code accordingly.
Also, the database is complicated making some queries are extremely complicated and easy to get wrong. Let the Core handle it when it can.
I am not against making direct queries the database but it is not something that should be done lightly. If this is a first plugin, avoid it if all possible. | stackexchange-wordpress | {

Set attached to state
In the media library every attachment post has an "Attached to" column. I've developed a plugin that adds author profile and a facebook like banner image.
I now discovered that the attachment posts, that are used as profile pictures, are not marked as "attached to".
I used a wordpress console plugin to get `WP_Post` objects of a linked and of an unlinked attachment. But I couldn't find any difference between them that I could use to set it manually.
Is there any way to set the attached ststus of attachment posts? | Attachments are attached to a parent post. So when you get an attachment object, look into `$attachment->post_parent`. If that is `0`, the file is not attached.
The parent post ID refers always to another post in the `posts` table, never to an user. To attach the file to a user, you could create a hidden custom post type and one entry per user. But I don’t think it is worth the efforts. There is nothing wrong with unattached files.
To change the `post_parent` value use `wp_update_post()`.
Pseudo-code, not tested:
$att = get_post( $attachment_id );
$att->post_parent = $new_parent_id;

Why does WordPress change a file's permissions?

Can I specify template to use with the_permalink?
Can I specify a template to use with the_permalink()?
Why I need this: when they click a link from a certain page, I want to show that user a different template (extra content) on the linked page. | The `the_permalink()` function links to the **single post view** for the given post-type. As per the **Template Hierarchy**, the page used to render the single post view is **`single.php`**.
So, if you want to modify the template used to render the page when clicking `the_permalink()`, create/modify `single.php`, or for a specific post-type, create/modify `single-{posttype}.php`.

implement separate templates for 1 post type
