Woocommerce blank screen variable product attribute image thumbnail
I am using woocommerce, I have setup a variable product. Under each attribute, when I try to add a thumbnail image by clicking on the Insert Into Post button for the Media Uploader dialog, the dialog box becomes empty without any content.
In the javascript console in Google Chrome, I get the following error: post.php:1310 Uncaught TypeError: Cannot call method 'replace' of undefined

How can I test how fast or slow my wordpress website it?
I have my FIRST wordpress website and I love it, however I'm not sure if it's my browser (Firefox 8.0.1 for Mac) or my computer or the website itself but it's going really slow.
MY SITE is in the finalizing stages and I want to make sure it's smooth. This is my first wordpress site so I can see myself adding a lot of things and maybe slowing it don that way?
First off, is it slow for you guys?
Where is a good site, plugin or article about how to determine how slow/fast your wordpress site it? Is there a handy plugin that can speed it up? Is there somewhere I can check to see how big my site it? What might be a specific thing slowing it down? | Try Pingdom. | stackexchange-wordpress | {

WordPress 3.3.1 single post template
Does anybody have any idea why on single posts there are no template dropdowns for template selections in WP 3.3.1? I did not find that either in the page administrative area.
Thank you | For page templates, click on screen options in the top right corner and check the Page Attributes box. If your theme has no page templates to choose from then the template drop down will not be shown.
Posts and other post types do not use or support page templates and never have. Only pages support them out of the box. You can install plugins however that let you have custom post templates. There is also the post formats feature. | stackexchange-wordpress | {

Hiding the media-new.php File URL option via jQuery
As the title says I'm currently having some difficulties hiding the File URL option via jQuery.
I've been trying this:
// add_action( 'admin_footer-media.php', 'cor_remove_tr_file_url' );
add_action( 'admin_footer-media-new.php', 'cor_remove_tr_file_url' );
/**
* Removes the 'File URL' row
*/
function cor_remove_tr_file_url() {
?>
<script>
jQuery(document).ready(function($){
$('tr.image_url').remove()
});
</script>
<?php
}
which works great on `media.php`, but somehow it isn't working on `media-new.php`.
Would someone perhaps know what I might be overlooking here?

Why is a 500 error generated by admin-ajax.php not going into the Apache error log?

Custom php page in WordPress theme?

How can I create an upload page for (and only visible to) specific users?
I'm working on a WordPress site we have for some software my lab is developing. What I'd like to do is add a page that would allow collaborating groups to upload their data to us for testing, but that would be hidden from anyone else visiting the site (i.e. the collaborators would have to be logged in to see the page). Ideally they wouldn't see the dashboard when logged in, but that's not too much of an issue at the moment. Are there any plugins that would make this easy? | The plugin Omni Secure Files has quite a nice upload interface and different wordpress user roles can be given permission to either upload or just view the uploaded files
**Update from comment**
Here's the code I put into a page template to get the basics of OSF working in the front of the site:
if (!empty($omni_secure_files)) {
wp_register_style('omni-secure-files',$omni_secure_files->plugin_url.'css/style.css',array(),false,'all');
wp_enqueue_style('omni-secure-files');
$omni_secure_files->menu_root();
}
The `wp_register_style / wp_enqueue_style` is necessary if you want to style it nicely. You mostly need to copy the required admin styles into the page template. At some point I might get round to releasing it as an extension to the plugin. I think the folks that wrote the plugin will probably get round to it at some point.

How can I force the Wordpress visual editor to preserve the line breaks after paragraphs?
If I write and put a line break, it make the paragraph tags appropriately, but on this one page the line breaks aren't there:
< | The editor is doing fine to add `<p>` tag on line break. I think what you need is to add some css to add margin to `<p>` tag so you don't have to add additional or empty paragraph tags (which i see on your current page).
try something like this on your css:
.entry-content p{
margin: 10px 0;
}
That should give you a nice margin on top and bottom of the paragraph tag. Also you might want to add some margin on `<ul>` and `<li>` to get a good formatting.

How to remove the tagline from the HTML <title>?
I'm using the default Wordpress 2011 theme on a new blog I'm setting up. I've got everything basically setup fine for now. I have experience with PHP/MySQL and HTML/CSS, but haven't used WordPress as yet.
When I set the blog up, it asked for a tagline under general settings, which I provided. This is showing below the blog heading, which is fine, however I don't want it to appear in the HTML title.

Local wordpress setup with SPAM in the incoming links dashboard section?
I am developing a website on my localhost and i just notice a bunch of incoming links in the dashboard's incoming links section, which doesn't look valid.
When i visit the urls i don't see a reffer to my localhost/domain.com.
the only plugin i had active was "Regenerate Thumbnails". I disabled the plugin but i can still see the links.
How can i fix this?
regards | The incoming links widget is asking Google for links to the domain you’re on right now. If your domain is `localhost` you get a lot of links – because that’s a very common domain name.

which imports feeds from various websites. There are two problems I would like help in solving. The first is that I would like to place a limit on the date of the oldest feeds retrieved, limiting all results to the last 7 days. Secondly when I add more than 10 feeds it really starts to slow down the page and gets me PHP timeout errors. How can I make it more efficient, so it doesn't require huge load times on every page load? Thanks. | Instead of checking and updating the feeds every time you do the shortcode, instead register cron tasks for each feed timed to their update schedule. Also saving the feed items as posts, and storing the GUID in the posts meta, then only saving the feed items that are new, will simplify things. It will also let you use WP_Query on posts instead of dealing with feed transients too. | stackexchange-wordpress | {

Function to get permalink of custom post type archives?
Is there a function that will return the permalink to a custom post types archives that is available to use in WordPress?
Something like:
`get_cpt_permalink("events")` which will return ` when `has_archive => true` on it.
If not what would I need to home brew my own? I'm thinking I would need to read `$wp_rewrite` and use something along the lines of `$wp_rewrite->get_extra_permastruct('events');` | This is what you are looking for `get_post_type_archive_link( $post_type );` | stackexchange-wordpress | {

Customizing page content layout
For a while now I have been building WordPress based sites for clients. These sites tend to be brochure sites so feature a collection of pages all with slightly different layouts within an overarching main layout and style.
Upto this point I have either created Pages in the WordPress admin panel and then created a page template with the content embedded into it (not great when the client want to be able to update the page) or created a new page and a generic "page" template and then placed content into this using HTML in the editor (not great for the user trying to edit the content in the editor, or when the editor decides to add more HTML tags)
Is there another way to easily create pages where the user can easily update the content using the editor but wont risk screwing up the layout? something like multiple editors or content areas in the admin panel? | Disclaimer: I have no affiliation with this plugin nor its author, it's just a plugin I've found to be indispensable in my Wordpress tool kit.

PHP Syntax Error on get_posts

get_meta_data within a loop

I read an old post on the wordpress support forums about custom loops like this, and I'm fairly certain that I'm not calling the $post_id properly, because if I manually insert a post_id it calls the correct data.. but either way I'm unsure where to go from here. Any help would be appreciated. | `query_posts()` is for main query, it would be more wise to use `get_posts()` function to get you events.

How to use images uploaded with custom implementation of thickbox like the_post_thumbnail() functionality
I have create a custom post type with meta boxes.
In metaboxes I have create some fealds that the use can use the WordPress ThickBox Media Dialog to upload his/her images for each post seperatly.
From the other side, the WordPress, when I upload an image as a Featured image, gives me some functions like the
the_post_thumbnail()
that allowing me to choose the image size that I need in my template.
So, the question is, can I use any function looks like the above one to print out the image sizes I like, that the end user has upload through the media box custom fields ? | If you're not opposed to using a plugin to achieve this, I would recommend the Multiple Post Thumbnails plugin.

What's the internal concatenation function for creating Excerpts with Wordpress?
I'm already familiar with the_excerpt() and get_the_excerpt() functions. These two functions relate specifically to some node/taxonomy/whatever (post, page, custom post type) inside of Wordpress, unless I'm mistaken.
What if I have some external text, and wanted to pass it through a concatenation function. Does anyone know the function to do that?
What I'm trying to avoid, is creating a new function or re-writing an old function to limit words inside of a string. For example,
> echo some_excerpt_function($text, $amount_of_words_to_limit);
I'm assuming Wordpress has something similar to this, that's why I'm asking. | Use `wp_trim_words( $text, $num_words, $more_text )`
The first argument is the text to trim, the second is the number of words you want and the third is the truncation text which defaults to an ellipsis.
The function is located in wp-includes/formatting.php line 1920 (v3.3.1) | stackexchange-wordpress | {

Show a different code on front page to other pages
I'm looking to display a list of posts in the header section on my template on all pages with the exception of the front page where I would like to show an image in place of the list of posts.
Is there a function within wordpress to detect the front page that I can use in my template code? or should I just be looking at PHP code that says if the URL matches X then show this, else show the other code? | You can use the wordpress template hierarchy to do just that. Specifically, you can put the code you want in `front-page.php` and then use `index.php` for the rest of them, though that's a rather bland way of doing design with what you have on your hands.
Alternately, there are the wordpress conditional tags which can be used to detect whether you're on a category page or the frontpage, etc.
### Edit
Using the `is_front_page()` conditional:
<?php
if ( is_front_page() ) {
// This is the site front page;
// put your front-page output here
} else {
// Put your default output here

Populate wordpress menu with link to custom field value (file download)
I have an additional menu that appears on some single.php pages. To this menu I would like to add an li with a link to a PDF which is uploaded to the post by a custom field (advanced custom fields helps with this).
I found a snippet on how to add todays date to my menu, and thought I could maybe use this as a starting point. However I´m not good enough coder to know where to go from here. I would appreciate some help with it!
This is the snippet I´m starting with: <
I need to make it display this instead:
<a href="<?php the_field('mcf_uppsagning-pdf'); ?>">Uppsägning</a>
I cant just replace it though and I dont know the syntax enough to know how to modify it. Please help :)
Thanks | Try this:
// Filter wp_nav_menu() to add additional links and other output
add_filter('wp_nav_menu_items','add_pdf_to_menu', 10, 2);
function add_pdf_to_menu( $items, $args ) {
if( $args->theme_location == 'extra-menu') {
$pdf = get_post_meta( get_the_ID(), 'mcf_uppsagning-pdf', true );
if ( $pdf )
$items .= '<li><a href="' . wp_get_attachment_url( $pdf ) . '">Uppsägning</a></li>';
}
return $items;
}
Essentially because you're in the context of the single page `get_the_ID()` will return the id for the post/page you're on. If that doesn't work try using `get_queried_object_id()` in place of `get_the_ID()`.

Replace image urls(absolute instead of relative) by using filter in single page

I mean if any img src file looks like `/images/2010/03/example.jpg` then it should be filtered and replaced with `
Can anyone give me the snippet? Thanks | Something like this should do it, you may have to fiddle with the `preg_replace()` to get it to work the way you need, but the concept (and, more importantly imo, the regex, is there).

'(/images/(19|20)(0-9){2}/(0|1)(0-9)/[^.]+\.(jpg|png|gif|bmp|jpeg))'.
'("|\')#';
$replace = 'src="'.get_site_url( $2 ).'"';

Need help with adding templates (archives and sitemap) to Wordpress child theme
I recently switched themes, and my old theme had templates for sitemap and archive (in fact the archive was one of my most viewed pages.)

The 'https_local_ssl_verify' filter
I have run into some WordPress code which does POST requests to API sites and in the POST parameters for the SSL property it has
$params = array( 'body' => $_POST, 'sslverify' => apply_filters('https_local_ssl_verify', false));
So why not simply put false or true? | The `apply_filters()` function lets plugins and themes override the value. So yes, you _could_ manually set `sslverify` to `false`. The code snippet you included will set it to false _in the absence of any filter._
Let's say I have a plugin that wants to force it to true. I would add this:
add_filter( 'https_local_ssl_verify', '__return_true' );
The `__return_true()` function is a special function in WordPress that automatically returns `true`. So if I add this code to a plugin or my theme's `funtions.php` file, it will force your code above to set `'sslverify' => true`.
It all depends on your local setup and what you're trying to do with the site. The use of `apply_filters()` merely makes things as flexible as possible. | stackexchange-wordpress | {

How can I dynamically generate an image with a static image URL?
What I'm trying to do is very simple.
Whenever someone visits, say `site.com/socialproof.png`, I want it to use a rewrite rule to point it to a file in my plugins folder.
Can I do this with WP's rewrite rules or do I need to manually add it to the `.htaccess` file? What would I use as the rewrite rule to do this? Thanks! | Using .htaccess rewrites wouldn't be a good approach since it would fail when the plugin is disabled.
You also can't rewrite image URLs with WordPress because its native request parsing does not recognize single file names. However, if an image doesn't exist, the web server will redirect the request over to WordPress for handling. This allows us to hook in and include your dynamic image template.
add_action('init', 'wpse_44612_init', 0);
function wpse_44612_init(){
if(preg_match('/socialproof\.png/', $_SERVER['REQUEST_URI'])){
require_once(ABSPATH.'/wp-content/plugins/SocialProof/classes/SocialProofMakeImage.php');
die();
}
}
With this approach, your URL appears as a static image, but is dynamically generated via your PHP class file.

Exclude the category in Wordpress
## My question:
This code retrieves the categories. I need to exclude the category number:81. Is there an easy way to exclude it in this code?
<?php
$cat_lists = retrieve_cat_data_sp( get_option('bn_exclude_home_lists') );
for ($i = 1; $i < count($cat_lists); $i++ ) {
if( (get_category( $cat_lists[$i] )->count) > 0 ):
?> | If retrieve_cat_data_sp is the function from this question then that returns categories except the ones given in the argument:
$cat_lists = retrieve_cat_data_sp('81');
It essentially a wrapper for `get_categories`. So to exclude multiple Ids
$cat_lists = retrieve_cat_data_sp('81,82');
If you want to exclude 81 as well as those IDs listed in `get_option('bn_exclude_home_lists')` then, assuming that option returns something in the form of comma separated IDs `'12,13,36'`:
$exclude = (get_option('bn_exclude_home_lists') ? get_option('bn_exclude_home_lists'):'');
$exclude .=',81';

How to make pages that arent indexed for ajax applications
I'm using a content section on my homepage to switch through multiple loops with ajax tabs and to do that a tutorial told me to make multiple pages and assign each page with a different template which contains the loop I want to display. But by doing that I'm creating top level pages that display loops on a blank page without styling. That makes me think they will get indexed and I'll have the unstyled pages showing up in searches. What's the right way to do this? | You can use the constant DOING_AJAX to check if a current request is AJAX or not. This would let you do something like this in your templates:

Retrieving custom field array value through db query
I'm trying to query the database for posts based on multiple custom fields. This is easy enough with the code below if values are simple:
$querydetails = "
SELECT wposts.*
FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
WHERE wposts.ID = wpostmeta.post_id
AND wpostmeta.meta_key = 'field'
AND wpostmeta.meta_value = 'value'
AND wposts.post_status = 'publish'
";
But how do I query a value that is stored in array form, like a:1:{i:0;s:8:"value";} ? | You can't query the database for a value in the array. However you can grab the entire array and parse the array to get your value. Check out PHP ARRAY-VALUES. More than likely you'll need to use a for each statement.
Does the value your trying to get appear in the same spot in the array? If so it should be easier to target.

How to create custom post listing in the admin?

TinyMCE Advanced newline problem
I am using TinyMCE Advanced plugin according to qTranslate in a wordpress 3.3 installation. **My question is:** why does tinymce translate visual editor new line ("enter" key) in a `<p> </p>` instead of `<br/>`?
Is it possible to change this behavior? | Go into Settings -> TinyMCE Advanced, and check the option `Stop removing the <p> and <br /> tags when saving and show them in the HTML editor`. This will allow you full control over those tags inside the HTML view.
For a single line break without overriding the editor, use `Shift+Enter`.
To override the editor and make `Enter` a single line break, put this into your `functions.php`:
function change_mce_options($init){
$init["forced_root_block"] = false;
$init["force_br_newlines"] = true;
$init["force_p_newlines"] = false;
$init["convert_newlines_to_brs"] = true;
return $init;
}
add_filter('tiny_mce_before_init','change_mce_options');
This does not convert `shift+enter` into `<p></p>` however, and this will cause some strange behavior for already existing content (if you're inside an existing `<p>` it will give two lines instead of one), so I would strongly recommend getting used to `shift+enter` instead. | stackexchange-wordpress | {

Typical wp_kses $allowed
I have a custom post textbox that I want to sanitize using `wp_kses` before I update my post meta.
I was looking for examples of common `$allowed` settings, but I have only seen this example:
$allowed = array(
'a' => array( // on allow a tags
'href' => array() // and those anchors can only have href attribute
)
);
What is a typical `wp_kses` `$allowed` setting? Can someone provide an example of what they normally filter for? | I would disagree with the solution posted by @JaredCobb, `wp_kses()` is much more flexible than the method he presented. It can strip out unwanted attributes from tags without destroying the tags themselves. For example, if the user put in `<strong class='foo'>`, `wp_kses()` would return `<strong>` if you did not allow class, whereas `strip_tags()` would remove the `<strong>` completely.
@redconservatory: The attributes you'll want to use are as follows:
$args = array(
//formatting
'strong' => array(),
'em' => array(),
'b' => array(),
'i' => array(),
//links
'a' => array(
'href' => array()
)
);
This will allow bold and italics with no attributes, as well as anchor tags with an `href` attributes...and nothing else. It uses the whitelisting principle, which @jaredcobb rightly noted is the better way to go here. | stackexchange-wordpress | {

I'm getting a '500 Internal Server Error' when I try adding menu items

> The WordPress core team is quite aware of this issue, and it is absolutely something that needs to be solved. It is an issue with how the menus are saved. Too much data is passed back.

Functions.php and includes
My functions.php file is getting on the long side. Is it all right to use includes to break it up (php includes I mean) or is this considered bad form? | Many theme frameworks and complex themes break up functions into different files and include them in one file called functions.php, sometimes within a folder called `inc`. If it's your own theme, you can pretty much do what you want.
If it's a theme to be released, end users typically look for a functions.php file as the default WP framework functions file.
The two latest default WP themes - twentyten < and twentyeleven < \- use one functions.php file, as that's part of the standard WP theme file structure.
But again, many themes use multiple files for functions, and if a user wants to work with or modify the theme, they will need a certain level of proficiency anyway. Code comments are helpful. | stackexchange-wordpress | {

How important is it to enqueue a theme's stylesheet?

Also, what about the theme's default stylesheet, should that be enqueued too? | It's important to enqueue the stylesheet because it will allow child themes the flexibility of dequeueing it as well as allowing it to be listed for dependencies and a multitude of other things. It just generally allows greater flexibility, both for you and for any other developers who interact with your code.
It's also important to note that using the default stylesheet in your theme is not a requirement.

How can I get a list of latest posts outside of my WP install?
I have a site with WP installed at /blog, and I'd like to just get a list of the latest blog posts to display on the site home page... that is to say, my custom (PHP) home page, NOT a Wordpress page.
I found this, but it doesn't work-- the latest version of Wordpress is looking for Translate_Entry.php or some other kind of class that it can't find.
Is there an easy way to do this, short of picking up and parsing the RSS feed on the fly? | You have several options.
## XML-RPC
< is the place to start. The API exposes a large number of methods to access WordPress data "outside" of the full WordPress context. Difficult to setup, connection requests overhead.
## wp-load.php
Include `wp-load.php` to load up WordPress. You will need to `chdir()` into WordPress first for this to work properly, depending on your environments and contexts. Easy.
chdir( 'wordpress' );
require( 'wp-load.php' );
foreach ( get_posts() as $post ) {
echo "<h2>{$post->title}</h2>";
}
This is very similar to the link you posted. The error you're getting is probably an include that is relative to some path. So change directories before and after.
## XML feeds
Parsing the feed may be overkill, unless you cache maybe. Highly discouraged. | stackexchange-wordpress | {

Featured Image Thumbnail Sizing
!
The image on the left is what it is currently looking like. I used developer tools to change the width & height of all the image fields for the image on the right, however I would like some sort of cropping to get a similar effect without the scaling issues. My code is below.
<div class="thumb">
<?php the_post_thumbnail(153, 115, true); ?>
</div>
.inner .thumb {
width: 153px;
height: 115px;
overflow: hidden;
} | I've approached this problem in a few different ways, here's some ideas:
1. Just grad the medium sized thumbnail with `the_post_thumbnail('medium');` (or any defined size that is bigger than what you want displayed), and apply a `.inner .thumb img {width: 153px; height: auto;}` css rule. If it's too tall it will get cropped from your `overflow:hidden;` on the container. This will cause css based image scaling, but maybe that's fine.
2. You could use `wp_get_attachment_image_src` to get an array with the image's height and width and use some mathematics with the ratio you want to resize or crop the image using php's image processing functions... this seems messy and overkill
3. Set your default thumbnail size in wordpress's media settings to 153x115 and use the proportional option. Like answer 1, this the excess will get cropped off by your container, you're just letting wordpress resize the image for you instead of css | stackexchange-wordpress | {

Conditional template tag for buddypress pages
I'm trying to assign a special template only to buddypress pages (activity, members, profile...). All other posts / pages use a different template. Problem is: I just can't find a good way to tell if a page is "rendered" by buddypress or by the wp "core". I've looked in the bp codex and found the template tag bp_is_member() and others, but none for an overall approach. Are there hooks that I could use or other template tags that I didn't find?
I'm not looking for a customization of the sidebar only, so conditional widget plugins won't do the job.
Any help is appreciated Heiner | `bp_current_component()` does not necessarily return a boolean - it returns `false` if not in a BP component, but will return the name of the component otherwise, as a string.
Internally, BP uses the function `bp_is_blog_page()` to do what you're asking - if it returns true, it's not a BP page. | stackexchange-wordpress | {

Get user info outside Wordpress
Not quite sure why this is happening, hopefully someone can help. I have a wordpress installation, lets say for arguments sake it's installed to < I have a file called test.php with the following code:
<?php
include '/php_path_to_blog/wp-blog-header.php';
echo get_current_user_id();
?>
Now the odd part is if i have a user logged in and place this file within my wordpress directory and call it by going to < it outputs the correct user id of the current logged in user. However if I move the file to the root directory of the site and call it by going to < it outputs 0 as if there were no user logged in.
It seems that some functions work properly outside of the installation directory and some don't. I would like them to work outside the wordpress isntallation directory.
Any help would be greatly appreciated. | Very similar to this question of a couple of hours ago: How can I get a list of latest posts outside of my WP install?
Use `chdir()` to move into WordPress root before including and even calling anything related to WordPress. The are cases where relative directory and file references are used, thus breaking many things.
You can return to the previous directory afterwards by storing the `get_cwd()` first.
$cwd = get_cwd();
chdir( 'wordpress_root' );
include 'wp-load.php';
// ... do stuff with WordPress
chdir( $cwd );
// ... continue happily ever after
Additionally, seeing that you're working with session cookies, the paths for these cookies are invalid for the URI you're working from. The browser will not send the WordPress authentication cookies that you have acquired previously since the domain roots are invalid and outside of the WordPress scope. You will need to alter the roots of these cookies from WordPress with something like this < | stackexchange-wordpress | {

How do I get my nav menu to show sub pages?
< is my website.
I've got the top menu which is the one that was in the theme when I started to customize it. It's got a test drop down that works just fine. I included a secondary menu under the slider with this code
<div id="secondaryMenu">
<?php
$menuID = 'bottom-nav';
$footerNav = '';
if (function_exists('wp_nav_menu')) $footerNav = wp_nav_menu( array( 'theme_location' => 'footer-menu', 'container' => '', 'fallback_cb' => '', 'menu_id' => $menuID, 'menu_class' => 'bottom-nav', 'echo' => false, 'depth' => '2' ) );
if ($footerNav == '') show_page_menu($menuID);
else echo($footerNav);
?>
</div>
It works just fine, except for the fact it does NOT show drop downs? I've got 3 pages underneath "Admissions" the furthest left item, and they don't show up? | First let me start by stating the @cale_b is probebaly right and you should first look at your css / jquery to ensure that your items arnt being hidden...
Also - you should change this:
'depth' => '2'
To this:
'depth' => 0
0 = show all & no need to surround it like this: '0' This is the right way 'depth' => 0
(since its not a string.)

Get the first post term
How do I get only the first term of a custom post type.
I can get all - no problem. This what I am using to grab all of them
<?php foreach ($terms as $term) {echo '<a href="'.get_term_link($term->slug, 'sitecat').'">'.$term->name.'</a>,';} ?> >> <a href="<?php the_permalink(); ?>"><?php the_title('', ''); ?></a></h2></span>
Would appreciate an answer using my code but any help is most welcomed | I'm not sure what you mean by 'first' taxonomy... but,
$terms = get_the_terms( $post->ID, 'mytaxonomy' );
returns an array of taxonomy term objects, so
$term = array_pop($terms);
Would give you the first term in the array. And then:
echo '<a href="'.get_term_link($term->slug, 'mytaxonomy').'">'.$term->name.'</a>,'
_(You may want to include some if statements, in case an empty array or error is returned (see`is_wp_error`)_ | stackexchange-wordpress | {

what is the cache directory for in my theme? (version control it?)
I was wondering what processes exactly use the `cache` directory inside my theme's directory. More specifically, I am wondering if I should add any of those files to my git repo. | If you use someway "compilable" WordPress theme (are they exist?!) cache-dir _may contain_ theme-files, processed by some tools and prepared for using by httpd-server of site.
As all and any artifacts, constructed from **versioned data** , these files can and have be excluded from versioning - **everybody** will be able to **rebuild** these files from _versioned source files_ | stackexchange-wordpress | {

How to disable Edit Post and Allow only Custom Field?
What I would like to know is if it is possible to disable the edit post function in wordpress based on User's roles. I try to explain better. Let's take an 'Editor' as role example: I would like Editors, Authors.... but NOT ADMIN to be able to write posts only using Custom Fields instead of the 'classic' built in edit post function of WordPress.
Is there anyone who knows how to do it (maybe it is only a sentence or 2 in functions.php) or who as/know a plugin that will let me do it?
Thank you very much! | You can remove post type support for the editor on a conditional basis. The following should work:
add_action( 'add_meta_boxes', 'wpse45113_remove_editor' );
function wpse45113_remove_editor() {
// change the capability and post type to whatever is appropriate
if ( ! current_user_can( 'install_plugins' ) )
remove_post_type_support( 'post', 'editor' );
}
I'm using `add_meta_boxes` because it fires not too long before the editor is initialized, but there are a number of hooks that would also work. You can similarly only add the meta box with the custom fields for those users within the same if block. | stackexchange-wordpress | {

Contact Form Security
Building my own contact form in Wordpress. Any there any security steps I need to consider other than the typical email etc validation and maybe a captcha. I am not sending any data to the database. | You should use a nonce to protect yourself from CSRF attacks.
Even though you're not sending anything to the database, I'd suggest using some of the built in data validation functions (there is even a `is_email` function for you to use!) to strip out any HTML from your email. `esc_html( striptags( $your_email_content ) )`, for instance.
You could also throttle contact form submissions from a single IP to prevent someone from submitting the same thing many times. I don't know of any contact form plugins that do that, but the WordPress comment system show you an error page if you submit too many comments within a certain period of time. | stackexchange-wordpress | {

phpBB 3 to bbPress
I am updating a diabetes forum to make it more extensive for which I have previously used phpBB 3. I have decided to use WordPress on the new build and have installed bbPress, however, I would like to import/transfer the existing users, forums and posts on phpBB into bbPress. There aren't that many of each to do manually, but I would still like to be able to do this manually. I have tried the ForumConverter and WP phpBB Bridge plugins but neither of them worked, so if anybody has any advice or suggestions that would be greatly appreciated.
I don't know if it's because I have downloaded the latest stable version of everything but strangely I don't appear to have any tables with the "bb_" prefix in my database either... | Never mind now. Fortunately (in this case) I have found an alternative solution to bbPress for WordPress - Simple:Press! I personally think that Simple:Press is much better not only because it allowed me to import everything from phpBB very easily but also because it seems much more comprehensive and well put together; - more comparable to phpBB!
So, basically Simple:Press is my answer and in a strange kind way, I'm glad I ran into problems with bbPress!... | stackexchange-wordpress | {
