Keyboard shortcut for headings on safari
When I use wordpress on PC, I can simply press ctrl+1 for Heading1 and ctrl+2 for heading 2... But when I use my mac it doesn't work. What are the shortcuts for heading styles on safari? | Short answer- there aren't any.
If you click the help button in the editor, then the hotkeys tab, you'll see the available shortcuts for the current OS/Browser. In OS X the modifier is Command instead of Control, but there aren't any shortcuts for headings. | stackexchange-wordpress | {

How to create Sub Sub domain Multi User blogs?
Hi to all I would like to create a big Wordpress network with this structure:
* sitename.com (Main website)
* cat1.sitename.com (sub website)
* cat11.cat1.sitename.com (sub-sub website)
* cat12.cat2.sitename.com (sub-sub website)
* cat2.sitename.com (sub website)
* cat21.cat1.sitename.com (sub-sub website)
* cat22.cat2.sitename.com (sub-sub website)
* cat3.sitename.com (sub website)
* cat31.cat1.sitename.com (sub-sub website)
* cat32.cat2.sitename.com (sub-sub website)
Is it possible using only one wordpress installation with subdomains? If it is not is it possible to share userdatabase (and why not also posts and all the stuff) between all the websites? Is there anyone that already did it and can help me to achieve this? Thank you very much! | While this question is several months old and you've probably figured something out already, I figured it was worth answering anyway. This is possible to do using the WP Multi Network Plugin. WordPress has the underlying structure to accomplish this, but no accompanying UI -- this plugin merely offers that interface.
Some things are not completely shared across _Networks_ , and I believe Users are one such example. If I remember right, users can span multiple networks, but it needs to be done by a super admin. Anyway, play around with it, you'll get it working how you want!

Automatically load Wordpress page on server every XX hours
I have a page in my Wordpress site that calculates post popularity and updates several meta fields on the posts and calls a few functions as well. This page is set to "Private" so that only myself and other admins can see it. Is there a way to load this page automatically every 6, 12, or 24 hours?
I'd be satisfied with a plugin, but generally prefer to write my own PHP code. | You could use the WP-Cron functions to scheduled events. Note though that this is pseudo-cron- it requires someone (or a bot) visit your site for the events to execute.
To fire events more reliably, search for scheduling cron jobs (linux) or scheduled tasks (win). Depending on your hosting, you may have access to simple tools to schedule events, for example cPanel has a GUI for setting up cron jobs. | stackexchange-wordpress | {

What function actually renders the wp_admin_bar ? How can I call it?
What function actually renders the wp_admin_bar? And how can I call it? I want to print out just the nodes / DOM for the actual menu. It would end up rendering something like this:

Admin table list API?
**wp-admin table lists - like post list**
Is there a API or something to build table lists in wp-admin?
With table lists I mean like the list of posts for example. It has columns, sorting, paging and so on.
**Admin loop - the right way**
When I create my loop I want it to look and feel like the core code, build it the right way.
**No API? Give me an article**
If there are no API like this, maybe point me to a great article about how to create it the best way possible. | Yes, in version 3.1 `WP_List_Table` class was introduced and admin started to move to using it.
As of 3.2.x it currently is not officially declared to be stable API to be used by developers, but in practice it is usually more viable approach than building tables from scratch anyway.

WP_Query - Order results by meta value
I've checked around and haven't seen an answer which works as of yet. I have a WP_Query with the following arguments:

update_user_meta: How many is too many?
I am working on a community portal that may in future cater to extremely large user base. All users have about 50 settings that needs to be stored to the user meta. These settings would be frequently accessed and overwritten with new values when the user saves changes to their profile.
This would lead to extremely large number of calls to update_user_meta courtesy: large user base and large number of settings per user.
Would these high number of calls to update_user_meta cause any performance degradation?
An alternative that I see, would be to write the user settings to an array and subsequently store the array to user meta using a single call to update_user_meta.
Which of the two appears to be a better solution?
Regards John | To answer your questions:
> Would these high number of calls to update_user_meta cause any performance degradation?
The Higher the number of calls to the database the slower its going to work since every query takes some (not much but still) time.
> Which of the two appears to be a better solution?
Recently I finished a project with similar amount of user settings and the solution i ended up with was to store as an array all of the data that i didn't need to query or search based on, (since when using array to store data in the data base it is stored serialized ) and the rest (data that needs to by queried based on) as single rows of data, which cut down the queries on one page from 68 to just 7. | stackexchange-wordpress | {

Uncaught SyntaxError: Unexpected Token Illegal

How to exit a plugin's execution mid-stream?
I have a plugin that I want to ensure runs ONLY on singular posts, pages, etc. I'm using the is_singular() function and it works great - except that all it does is return execution to the rest of the plugin if I do this:
function singular_check(){
if(is_singular())
return;
}

add_action('wp', 'singular_check');
I need to actually make my entire plugin bail out at that point, and return to executing whatever else was downstream of my plugin.

function wpse30291_template_redirect()
{

}

Making plugin to use different table prefix cause permission problem

How do I remove the admin bar (styling) from frontend only?

When to use is_home() vs is_front_page()?
I've found that `is_front_page` appears to return true when I'm viewing the home page and have a single sticky post assigned there.
It also returns true when I've assigned a page as the static front page via _Settings > Reading_.
Why would I ever want to use `is_home()`? | `is_front_page()` returns true if the user is on the page or page of posts that is set to the front page on _Settings->Reading->Your homepage_ displays
So if you set `about us` as the front page then this conditional will only be true if showing the _about us_ page.
`is_home()` return true when on the posts list page, This is usually the page that shows the latest 10 posts.
If the settings under _Your homepage displays_ are left at default then the home page will return true for both `is_front_page()` and `is_home()`
An example of using `is_home()`:
* You have set your posts page to a page called _News_.
* A user navigates there and in the header you want to show additional navigation
* You could use `is_home()` to do this. | stackexchange-wordpress | {

File Attachment display title in template
I've got a custom post type with a file upload field. In my template file i'm using this to display a link to that file.
<a href="<?php the_field('downloads'); ?>">Download PDF</a>
What i want is to be able to have it display the file title. So instead of Download PDF it will say the files title.
What php would go inside the code i'm using?
Thanks
EDIT: Here's the code that i put in the comment below. I'm guessing this is what you were asking for. I looked through the files for the plugin i've used and found this function.

{
$value = get_field($field_name, $post_id);
if(is_array($value))
{
$value = @implode(', ',$value);
}
echo $value;
}

Query Posts Creates 404 Error
When I'm on archives pages I am using the code below to query posts. In my theme options to_count_home calls the number of posts.
WordPress isn't generating the correct number of pages based on posts_per_page. Instead it is generating pages based on the number of posts per page I have selected in my default WordPress settings. For example, if I have 10 posts per page in the settings then set posts_per_page in the code as 5, when I go to the second page (which should have 5 posts on it) I get a 404 error.
Here is the code I'm using:
<?php
$per_page = get_option('to_count_home');
query_posts("posts_per_page={$per_page}");
if (have_posts())
?> | You are not modifying your query, but nuking it completely. Please see `query_posts()` documentation in Codex on how to correctly re-run query with changed arguments. | stackexchange-wordpress | {

A way to detect which page a post is on
I'm wondering if there is a good way to tell which archive page a post came from. I essentially just need the post's position in the total order, then divide it by the 'posts_per_page' option. The hangup I'm having is getting that position or offset of where the post sits.
EDIT: All while being on the SINGLE POST template.
There, no matter what, the usual $wp_query global and 'page'/'paged' query vars are always 0 - so those won't get me anywhere. | Alright, nevermind. I got this solved by doing this at the top of the single post template:

$position_posts = get_posts($position_query); $count = 0;
foreach ($position_posts as $position_post) { $count++;
if ($position_post->ID == $current_id) { $position = $count; break; }
}
$posts_per_page = get_option('posts_per_page');

Create New Admin Menu Section - Like how custom post type works, in a way
I've been working with Wordpress off and on for years now, but I haven't gotten entirely immersed with the framework. I have no problem creating plugins that use custom post types, but I'm looking to add a new section in the admin that isn't for posts, but rather my own custom tables.
I know how to create the custom tables on installation of the plugin, I'm just looking for the right information to create a new menu section with subsections, but I'm having a hard time finding the answer.
What functions/hooks do I need? I'll figure out the rest after that. | Check out the Administration Menus section in the Codex, I actually used it pretty heavily over the last couple days to create a sub-menu and it helped a lot. It goes into detail on the top level menus as well.

How to get Wordpress to NOT alter the permalink structure when adding a static page?
This is driving me nuts and I'm hoping someone knows of a way around it.
Say I have a permalink structure of `/%postname%/` and I have URLs like `www.domain.com/blog/post-name/`. So I go about linking and what have you out in the big bad internet.
But, now I decide I want to add a static home page. Say it's a page called "my page". Suddenly WP changes ALL my permalinks to look like `www.domain.com/blog/my-page/post-name/`! So all the links I have created now point to the wrong place, and my plugin which does some things by retrieving the `post_id` of the requested url, utterly breaks because that page no longer exists.
Why on earth the WP team would think this is a great idea is beyond me, I simply want to set a specific page to appear when someone visits the root of my blog, not insert that page into the path of all my links.
How can I disable this "feature" or otherwise work around it? | It sounds like user error to me, or possibly a plug-in. I am leaning towards operator error. WordPress just gives you the vehicle, your the one at the wheel.
The good thing about WordPress is it allows people without the knowledge it takes to build a website a chance to jump right in, sink or swim. It's all a matter of how you set it up.

How do I make images appear in the beside blog post summaries?
I don't know if this is a WordPress question or a CSS question...
On my blog, in the list of post summaries, an image from a post appears beside the post's summary in the list of posts.
But that only happens with one post.
Other posts have images, but no thumbnail image appears in the list of post summaries.
I want to make it so that whenever I include an image or a video in a blog post, in the summary list, a thumbnail of the image appears. If I include more than one image in a blog post, then just one thumbnail appearing is ok.
Ideally, clicking the image would click into the blog post.
You can see the list of summaries at <
The one thumbnail is 11 posts from the top.
Thanks, | It's hard to tell without seeing the theme files but I assume the one image is displaying because it is set as the "Post Thumbnail" or "Featured Image" on that particular post and that all other posts aren't using that feature.
The easy solution in that case would be to make sure you set any images you use in the post as the "Featured Image" as well.
If that isn't the case then you can modify your themes function file to grab the first image of any post and then modify your index.php file to include that image if it exists.

Query posts by custom taxonomy ID

How to keep plugin translations after updates?
bbPress' language folder (`wp-content/plugins/bbpress/bbp-languages`) has that warning:
/**
* Do not put custom translations here. They will be deleted on bbPress updates.
*
* Keep custom bbPress translations in /wp-content/languages/
*/
Actually, this is not a new problem and yes, they are right. This is a big problem if you are using WordPress plugins with a non-English language.
Basically, I translated bbPress and created `.po` and `.mo` files. Files are working if I put them in their normal `wp-content/plugins/bbpress/bbp-languages` folder. But as the above warning says, they will delete on update. But the problem is translations are not working if I put them in the `wp-content/languages/` folder as suggested in bbPress.
I think there must be a hook or something I can activate it but what is the best solution for it? Simply I want to keep plugin language files in `wp-content/languages/`. | You have to replace the call to BBpress’ language file.
A good place to do this is a language specific file in your general languages directory. For Turkish it would probably be a file named `tr_TR.php`. This will be loaded automatically and _only_ if it matches the language of your blog. It will not be overwritten.
BBPress doesn’t use the function `load_plugin_textdomain`, it uses `load_textdomain` instead. Here you can find a filter:
$mofile = apply_filters( 'load_textdomain_mofile', $mofile, $domain );
So in your language php file just add a filter to change the path:
function load_bbpress_tr_mofile( $mofile, $domain )
{
if ( 'bbpress' == $domain )
{
// replace this. :)
return 'FULL_PATH_TO_YOUR_FILE';
}
return $mofile;

Thumbnail Image Rounded Corners w CSS (or any other good method)
I've been researching how to display thumbnails with rounded images, but every solution ends up running out of gas.

`border-radius: 15px;`

<div style=" ";

CSS/JS files in WordPress
In web development, I get used to place css/js files under separate folders (css folder, js folder ..etc).
What I am experiencing in WordPress is that I cannot access these folders in WordPress Admin Editor Page, the editor only displays the files under the main theme folder, not the nested folders.
Is there an option to enable showing nested folders? is there a plugin to accomplish that? If not, then what is the best practice to follow for placing files and folders under WordPress folder? | The theme editor is located under _/wp-admin/theme-editor.php_ and uses `get_current_theme();` to give you the first files to edit. From the returned `array` of theme data, it uses `'Template Dir'` to locate the directory and `'Template Files'` to give you a list of files to edit (loops through the files with a `foreach` loop). For stylesheets it uses `'Stylesheet Dir'` and `'Stylesheet Files'` to loop through.
Point is that:
**1.** there are no filters or hooks, so you'd need to modify core directly (which is not recommended, as your changes would be overwritten on update) and
**2.** you'd need to write a function that reads the whole folder, finds all subfolders and then another one to find all containing files and last loop through them too. | stackexchange-wordpress | {

Is there any global functions.php file which works for any theme?
Is there some global kind of functions.php file that works for any theme?
The problem is here:
When I change a functions.php file in any theme, I need to take care of two changes: First, I need to take care of the updates of that theme. Second, I need to take care of changing the theme of the site.
So, instead of making changes in the functions.php of a theme, is it possible to make changes in some functions.php file that is independent of any theme? | The difference between theme and non-theme code is organizational rather than technical. Any code that is active contributes to resulting environment, does not matter where it is loaded from.
There is number of places where code gets loaded from, which are not part of WordPress core:
* `wp-config.php` configuration file
* active theme (and its parent in for child themes)
* active plugins
* must use plugins
* drop-ins (these are somewhat advanced and serve very specific purposes)
Typical place for your own code, that should not be part of theme, is to create a plugin. Other approaches do not have benefits from generic case, but forfeit interface (managing through admin area) and technical (activation/deactivation/uninstall events) conveniences of normal plugin. | stackexchange-wordpress | {

Why does hitting enter in Visual Editor add <p> instead of <br>?
Why does hitting the enter key in Visual Editor add `<p>` instead of `<br>`?

Custom Post Type - Upload Form

Menus, but not by theme location
I'm trying to figure out how to display a menu that has been created, but without having to assign the menu to a theme location.
From what I can tell, you have to assign a menu to a theme menu location and then `wp_nav_menu calls` a menu from whatever location you want.
I don't want to have to assign a menu to a theme location. Instead, I want to be able to create a menu and then query it within my theme... regardless of theme location.
I've created a plugin for myself that uses `wp_get_nav_menus` to list all of the menus I've created... I can then assign any menu to a page/post. Now, I'm stuck trying to figure out how to retrieve that specific menu... again, not menu theme location.
Anyone? | `wp_nav_menu` takes an optional argument called `menu`, which will fetch any menu by name, slug or ID.
If you just want post objects (or anything but the menu HTML), `wp_get_nav_menus` is the way to go. Otherwise, use `wp_nav_menu`. If you need it to return the menu HTML instead of echoing, there's an argument for that as well: `echo`. | stackexchange-wordpress | {

Repeatable configuration package
It's normal that a developer or a shop will spend several hours on each project running the same configuration options (for permalinks, SEO options, user roles, plugins that you always use etc.).
I'm coming from Drupal, where installation profiles have allowed me to preconfigure a set of configuration options that I can replicate across dozens of sites.
This has saved me and my clients hundreds of hours.
I now have an opportunity to do the same in WordPress. I'd like to create a script that installs WordPress, installs some plugins and sets some initial configuration options. This has the potential for useful time/cost savings when scaled across many sites.
Is this feasible? Or am I barking up the wrong tree? | Not exactly what you are asking for, but very close.
There is a concept of 'dropin' plugins that exists primarily to override or add to core functions
The dropins will always load.
So one ftp's up wordpress including whatever plugin files you want that will create your default environment. These should be in the top level wp_content folder.
I have one called **install.php** which overwrites the pluggable function
wp_install_defaults
with my own set of defaults (starting pages, default widgets, categories, taxonomies etc etc. ) It could load starting options for other plugins as well and possibly activate them.
Then you click the famous 5 min install (the 'script' you mention). It installs wordpress and applies your custom options from the dropin plugin.

How can I include PHP-Code to my post?
I would like to use PHP in some posts. These posts should look like normal posts, be in the archive and categories like normal posts an have tags.
I don't need PHP in every post, but it would be great if I could use it in some.
I saw that it is possible to create custom page templates which seems to be almost what I want, but I want it for posts. How can I get it? | You can edit the `single.php` and/or `content-single.php` files in your theme.
Then it depends what you mean by "some". You could apply some conditions to your code (only certain categories, certain tags, certain specific post IDs only, etc.)
You could also create a custom post type "myspecialposts" and create `single-myspecialposts.php` (codex) | stackexchange-wordpress | {

Alphanumeric usernames and error message for it
I'm facing a problem where I haven't seen proper answer anywhere. What I need help with is this:
How can I prevent my users registering non-alphanumeric usernames? To be exact, I could prevent it by using something like:
function validate_alphanumeric_underscore($string?) { return preg_match('/^[A-Za-z][A-Za-z0-9]*(?:_[A-Za-z0-9]+)*$/',$str); }
But what is the string I should/could use and how can I echo error message saying that the username inputted had invalid characters?
Cheers! | ### Check for alphanumeric
For more details, look at the regex Q on SO.
$name = 'input string 123";
// Doesn't allow:
// Pre-/Appending white space
// Not more than one space in between
// Non-alphanumeric characters (lower case)
if( ! preg_match( "/^[a-z0-9]+([\\s]{1}[a-z0-9]|[a-z0-9])+$/i", $name ) )
{
// Output Error Message
}
// Or: Does only allow
// Alphanumeric character (lower & upper case)
// Dash & underline "-", "_" - makes (imho) sense
if( ! preg_match( "/^[A-Za-z0-9-_",'\s]+$/", $name ) )
{
// Output Error Message
}
### Error Message
You need to do this via Ajax. Best would be to look over the search results. Another (maybe) good reference would be to inspect the code of some ajax login plugins for a "how-to". | stackexchange-wordpress | {

How to refine WP-Query with further criteria
I have a WP-Query which I pass post IDs to via
'post__in' => explode(',', $my_ids)
I then want the ability to refine this list by a custom field value (if present).
I have tried including the custom field test in the args for WP-Query but I get my ID list **PLUS** the custom field post IDs (instead of my IDs filtered by the custom field value).
I also tried adding a query_post after the WP-Query as a filter but that didnt work at all.

Got a problem with a widget
i am trying to build a widget that would display a list of top authors on sidebar..
This is not my first widget but it is my second one so my apologies if i am way off..
The problem is that when i drag the widget into the side (in admin ofcourse) and saves it apears no where..later when i check i see after refreshing the widgets page it doesent apear to exist..
**here is my widget code:** \--> <
i know it rather langthy but can anyone help / give an idea as to why this is happening? | It sticks if you don't include `id_base` in `$control_ops`, when you pass it to WP_Widget in the constructor.
Looking at the core code it looks as though `id_base` is actually the first arg to WP_widget and the `$control_ops` array should only carry 'width' and 'height' keys. | stackexchange-wordpress | {

Parent/Child pages
I find that the parent/child pages in the "Pages" area of WordPress has become a bit confusing since the introduction of the new menu creation area.
Using the new menu system, as far as I know I can set a page which is actually itself a child page (in the pages section) to be a parent of a page which is actually itself a parent.
Can someone tell me, is the whole parent/child pages scenario now superseded by the new menu system, and unless we plan on using wp_list_pages in the theme should we avoid having child pages altogether and instead just decide where they go in the menu area. What is normaly done on a site that doesn't use wp_list_pages ? | > Using the new menu system, as far as I know I can set a page which is actually itself a child page (in the pages section) to be a parent of a page which is actually itself a parent= **TRUE**
>
> **What is normaly done on a site that doesn't use wp_list_pages?** I can't speak for all, but I do just as you mentioned. I order the menu myself. If you don't need to manually arrange your sites menu and you find the wp_nav confusing you're probably better off using `wp_list_pages` for you menu, and using the page order in the Edit Pages screen to control your menu order. | stackexchange-wordpress | {

How many Custom Post Types to register?
My current WordPress site only exists of pages. The structure is as simple as this:
example.com/hotels
example.com/attractions
example.com/restaurants
I want to use Custom Post Types to add listings about individual hotels, attractions and restaurants. The new structure will look like this:
example.com/hotels/myhotel
example.com/attractions/myattraction
example.com/restaurants/myrestaurant
With myhotel/myattraction/myrestaurant being a Custom Post Type.
All listings share the exact same custom fields.
My Question: Do I need to create 3 Custom Post Types (hotel/attraction/restaurant) or should I register just 1 "global" custom post type - eg called "Place" - and specify if its a hotel/attraction/restaurant using hierarchical Custom Taxonomies?
What are the advantages/disadvantages of these different approaches?
Thanks! | Personally I would structure it like a CPT for each Hotels, Attractions, Restaurants. Then a custom taxonomy that ties them together for instance "Places" with children like "Locations", etc.
If the site has a lot of connected data it is a really good idea to sketch out the relationships on paper or using software like Visio so you can visually see how it all fits. | stackexchange-wordpress | {

editor text cut off when using 2 spaces (after periods)
I have noticed that my TinyMCE editor in Wordpress MU 2.9.2 loses text after a double space when you save a blog post. This is a problem because some users habitually use two spaces after a period.
In these two examples, there are two spaces between "test" and "test":
* "test test" ("test__test") becomes "test" when the blog is saved
* "test test, the rest of my long blog post" ("test__test,_the_rest_of_my_long_blog_post") becomes "test" when the blog is saved
_**Edit_** :
I updated to WP 3.2.1 and can confirm that this is still an issue. | Problem solved:
In 2.9.2 under "New Blog Defaults", the field "Encoding for pages and feeds" was blank and should have been `UTF-8`. When I updated this field on all blogs, the problem went away.
In 3.2.1 you can edit this value on a blog by blog basis on the reading settings page: `/wp-admin/options-reading.php`. I'm not sure what the default value for new blogs in 3.2.1 is, or if there is somewhere to change the default, but I'm guessing it is `UTF-8` | stackexchange-wordpress | {

How to disable admin flyout menus?
Seriously, I hate flyout menus with a passion, and now they're popping up all over the place in the admin screen. (They are particularly heinous when you use the blue admin theme, because they add a dark arrow. Eye dirt.)

Problem with <code> tag

How to add post featured image url to inline background url()?
I'd like to get a post's featured image and use it in the style="background: url()" of the post. I thought this would do it, but alas I was wrong because this outputs the whole (img src=""> stuff.
<div style="background: url(<?php the_post_thumbnail( 'thumbnail' ); ?>
) !important;">adasdasdasd </div>
I tried get_post_thumbnail but don't think I have the format right.
Any thoughts? | You just need to retrieve the src attribute of the thumbnail:
$thumb_src = wp_get_attachment_image_src ( get_post_thumbnail_id('thumbnail'));
`$thumb_src` is then an array containg the url, width and height of the thumbnail image. So something like...
<div style="background: url(<?php echo $thumb_src[0];?>
) !important;">adasdasdasd </div>
should work. | stackexchange-wordpress | {

How to edit posts with the new wp_editor api?
I am using bbPress 2x and modified the plugin to use the new wp_editor in place of the textarea for adding new topics and replies. This part works beautifully.
Where I am stuck is when a person clicks edit for a topic or a reply. The post content is not showing up in the editor.
I'm probably just missing something really stupid, and hoping someone can chime in on how to fix this last piece.
Here is what I am using: `
$tabindex = bbp_get_tab_index();
$settings = array(
'wpautop' => true,
'media_buttons' => true,
'editor_class' => 'tumble',
'tabindex' => $tabindex
);
wp_editor( '', 'bbp_topic_content', $settings );
`

**EDIT**
Just got an answer to my question, and it works great
Thanks go out to: <
`
$post = get_post($post_id, 'OBJECT');
wp_editor(esc_html($post->post_content), 'textarea01', $settings);
` | For the sake of completeness, I am going to post an answer based on the solution you edited in your question.
$post = get_post( $post_id, 'OBJECT' );
wp_editor( esc_html( $post->post_content ), 'textarea01', $settings );

How to list Tags using get_tags in an html table?
Any suggestions on the simplest way to display tags using get_tags in an html table (4 columns across) ?
Example:
Tag 1 | Tag2 | Tag 3 | Tag 4
Tag 5 | Tag 6 | Tag 7 | Tag 8
I'm using the following code to display tags, I found it in codex.:
$tags = get_tags();
$html = '<div class="post_tags">';
foreach ($tags as $tag){
$tag_link = get_tag_link($tag->term_id);
$html .= "<a href='{$tag_link}' title='{$tag->name} Tag' class='{$tag->slug}'>";
$html .= "{$tag->name}</a>";
}
$html .= '</div>';
echo $html; | This is what I tried and it works well. I am using `array_chunk`, but I'm also adding a check to see if a chunk has less than 4 values (as you want 4 columns), then just add a blank `<td>`, which will avoid the mark up from breaking.
<?php
$tags = get_tags(array('hide_empty' => false));
$tag_groups = array_chunk($tags, 4);
$t = '<table>';
foreach($tag_groups as $tag_single)
{
$t .= '<tr>';
for($i = 0; $i < 4; $i++)
{
if(isset($tag_single[$i]) && !empty($tag_single[$i]))
{
$tag_link = get_tag_link($tag_single[$i]->term_id);
$t .= "<td><a href='".$tag_link."' title='".$tag_single[$i]->name."'>".$tag_single[$i]->name."</a></td>";
}
else
{
$t .= "<td></td>";
}
}
$t .= '</tr>';
}
echo $t .= "</table>";
?>
