trouble with my loop
I am trying to exclude categories from my blog page. I have the code all set up and according to the codex, this should work
$string = '-' . implode( ',-', explode( ' ', $data['exclude_categories'] ) );
The above line will print this to the screen upon testing
-homepage,-recent-news
Those are the two test categories that I am trying to remove from the blog page. Then I start my query like so
<?php query_posts($query_string . '&cat=' . $string);?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
my other code stuff here
when I test the blog page, all the posts show up. I can't figure out what is wrong. | `cat` accepts category IDs, not slugs or names. a better method here is to use the `pre_get_posts` action, the Codex page has an example that does exactly what you're trying to do. | stackexchange-wordpress | {

Don't post or draft if post already exists

I am using IFTTT to update my blog and sometimes it posts multiple times. | I have no idea what IFTTT is but you can use the `save_post` action hook to do a check for duplicate posts.

Excluding a custom taxonomy term breaks wp_get_post_terms
I'm trying to exclude one custom taxonomy from an archive page, and then show the terms of the returned posts.
When I run WP_Query to exclude the custom term, it returns the posts correctly, but no longer fetches the terms array when using `wp_get_post_terms()`. I suspect that not querying in the positive prevents it from fetching the terms. Here's what my code looks like:
$query = new WP_Query(
array( 'tax_query' => array(
array(
'taxonomy' => 'documenttype',
'field' => 'slug',
'terms' => array('pressreleases'),
'operator' => 'NOT IN'
),
) )
);
//then later, in the loop ...
$terms = wp_get_post_terms($query->post->ID,'documenttype');
// var_dump($terms) shows an empty array | Thanks for your help everybody.
I was using a custom post type and forgot to include
'post_type'=>'my_custom_post_type'
I finally got to the problem by doing a `var_dump` on the `WP_Query` object and looking at the SQL. Running the query directly on the database and picking through it, I eventually found my error. | stackexchange-wordpress | {

Menu items id's - are they 100% unique?
With regards the menu item id's WP generates such as `menu-item-814`, are these 100% unique in nature?
I know they are unique at the time, but are they always unique? Meaning that if I was to delete something that had the id of 814, is it possible that some other menu item could now be assigned this ID? ...or if WordPress was updated do they still keep the same ID's?
I ask because I want to assign something to a certain menu button via JavaScript but on the off chance the button is removed I don't want to be applied to a new button that has now been assigned that ID. | Yes it is always unique. id 814 cant be applied again unless you update it manually on your DB.

Admins can't edit each other's posts

How do i structure my theme folder to avoid one huge list of files
When working with a worpress site with lots of custom post types and lots of page templates, my theme folder is looking messy. What are the accepted best practices to organise code files in WordPress?
a couple of the limitations i'm coming up against are that templates are chosen by name, so i can't group files by prefixing them. Also custom post template files can not be in sub directories. Also header and footer can not be in subdirectories.
How can i organise my code better? | Not a full answer, but I can at least answer this question:
> Also custom post template files can not be in sub directories.
Everything, that you can load via `get_template_part()`, can reside in a subfolder:
get_template_part( 'subdir/part', 'suffix' );
It's as easy as that. Now you've your part inside
~/wp-content/themes/theme_folder/subdir/part-suffix.php
* * *
_Slightly off topic._
Then there're some nice tricks, like using the post format or post type as part name:

'content'
,get_post_format()

Is it possible to put next and previous category links?
I'm not trying to navigate to the next post within a category, but to put previous category and next category under the category description on its archive page and navigate between archive pages.
I've searched, but I'm not sure this is even possible without hardcoding categories, and I don't want to do that. I'd like to dynamically link.
Not asking anyone to write any code for me, just asking does this sound like a good starting direction for what I need to look at doing:
Build a get_next_category function by using the wp_list_categories, then pulling the adjacent from that list and turning it into a link?
In short, I want a category archive page to show a category title, description (know how to do both of those), then next and previous category links before it shows the posts. I am not creating a list of categories, just navigation links.

using Ajax: call to undefined function get_option
I am using ajax on my template to load a file called counter.php. When I click a button, it is supposed to increase the counter. But when I click the button I get this error "Fatal error: Call to undefined function get_option()".

I am not sure what is wrong. Do I have to include any wordpress files on this php file ? | Basically, if you're going to be making calls to WordPress functions, then you should be in the WordPress environment, which means that you should not be calling your own files to begin with, but should implement your AJAX call within a WordPress hook.
Read up on this: <
That article describes how to implement AJAX requests within WordPress plugins, but it works equally well in themes or in any other code that WP loads.
Essentially, you hook a function to wp_ajax_* or wp_ajax_nopriv_* and then make your request through the the admin-ajax.php file instead of directly to your own file.
Side note: Implementing a counter like you're trying to do won't work particularly well, because you have a race-condition there. More than one person can be visiting your site at the exact same time. Storing counter data in the DB like that isn't going to scale to a very large site with lots of requests, although it will work fine for smaller sites. | stackexchange-wordpress | {

Custom post type - order field
In a custom post type, is there a way to include the "order" field that is available for pages?
Is there any built-in logic that prevents duplicate values in the "order" field?
The idea is to be able to sort a custom post type by a user-specified order, then alphabetically by a string-based custom field. | When declaring your custom post type using the register_post_type function, you have to add 'page-attributes' to the support field, like in the following example:
register_post_type('myposttype', array(
'supports' => array('title', 'editor', 'page-attributes'),
'hierarchical' => false
));
You'll need to add any other supported meta boxes as well to the 'supports' field, see < for more information about the register_post_type fields.
Also as far as I know there isn't any built in way to prevent two of the same order, this is because you can create sub-ordering based on heirarchy (so one group of children pages can have a different ordering than another) | stackexchange-wordpress | {

What triggers these wordpress queries on my homepage?

require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/themes/baracuda/index.php'), setup_postdata, get_userdata, get_user_by, WP_User->init, WP_User->for_blog, WP_User->_init_caps, get_user_meta, get_metadata, update_meta_cache
Second:
SELECT * FROM wp_users WHERE ID = '1' | Are the queries themselves displayed or are the results displayed? If the results of those queries are being output onto your homepage it's a potential security vulnerability.
The query returns user data including username and password hash for user ID 1 of the wp_users table, which is the administrator user that Wordpress creates when first installing.
I recommend changing the administrator's password and removing the code from the homepage, and checking other template files for similar code.
Also its generally a bad practice to run SQL queries in theme files, as there are built-in functions in Wordpress for accessing user data. | stackexchange-wordpress | {

Wordpress Multisite - is it possible to put the main site in a subdirectory?
I am creating a site that has different language versions and the requirement from the client is that all language versions are:
1. A different site on a Multisite setup
2. They all have address like this: mysite.com/en
Since the main site is in english, it's address actually has to be mysite.com/en, not just mysite.com
If possible, I wouldn't want to make a redirect from the main site to just a subsite that has the address mysite.com/en, but would like to use the actual mainsite with the subdirectory address?
Reasons: admin interface & database are cleaner + consistency. | No, not without major refactoring and lots of custom rewrite rules. The thing just isn't geared to do that without some restructuring.

How would I attach media/images to a post based on a ID stored in a each post's custom field
I have converted a site over to wordpress recently. I was able to import all the posts via a CSV importer, but not the images associated with each post. The post type is " **machinery** ". The custom field with the post's previous ID on the old system of each post is called " **machinery_legacy_idLocation** ". I have an additional table called " **legacy_images** ".
" **legacy_images** " has 2 columns " **ListingID** " and " **imageurl** ".
" **ListingID** " in the " **legacy_images** " table matches a post with the same " **machinery_legacy_idLocation** ".
Now the "imageurl" matches the title of a corresponding image that I have already added to the media library in Wordpress.
Basically I just need to figure out a way to reattach all these images to all these posts after the move. | `wp_insert_attachment` will insert an attachment post for a given parent post ID and filename. You can write a little script to query for all your posts with the legacy key, get their associated image paths, and call `wp_insert_attachment` for each. | stackexchange-wordpress | {

How do I remove the post format meta box?
Is it possible to remove the "Post Format" meta box from the edit/new post page? The blog in question has a lot of users that keep messing with that but it only uses the standard format post.
I'm kind of new to wordpress so excuse me if this is a really obvious one.
Thanks. | That gets added because your theme supports `post-formats`.
You can either use a plugin (or a child theme's `functions.php`) file to hook into `after_setup_theme` late and remove theme support:
<?php
add_action('after_setup_theme', 'wpse65653_remove_formats', 100);
function wpse65653_remove_formats()
{
remove_theme_support('post-formats');
}
Or look for the the line in your theme's `functions.php` file:
add_theme_support('post-formats');
and remove it.
The first option is a better bet. Stick it in a plugin and it will be there for the next theme you use as well. | stackexchange-wordpress | {

Apply html elements in php statement
I know this is probably going to sound like a beginner question ... to which it is in some sort.
I have this statement in my one plugin that i am working on:
add_post_meta($newpostid, 'name', $formdata['your-first-name'].$formdata['your-last-name']);
Which in turn will add FirstnameLastname in a custom field.
What i would like to do is add a space between the first and last name like this:
Firstname Lastname

add_post_meta($newpostid, 'name', $formdata['your-first-name']. echo ' ' . $formdata['your-last-name']);

Any help would be welcome. :) | Do this instead:
add_post_meta($newpostid, 'name', $formdata['your-first-name'] . ' ' . $formdata['your-last-name']);
This uses PHP string concatenation to add a space; the `echo` isn't necessary in in this instance because WP will do it itself, later. You probably can't force a non-breaking space there, either, since WP will escape all its output. | stackexchange-wordpress | {

Preview page/post revisions without overwriting current content
Is it possible to add or update a Post/Page without it overwriting the current content that it on there? I need to make some edits to a page, but I need to have someone review it before I can publish it and I don't want to overwrite the current content that is up there.
Any suggestions? | WordPress has built in Revision Management.
You can set the saved revisions to a custom number in the wp-config.php file in your installation.
define( 'WP_POST_REVISIONS', 30 );
**NOTE:** You should be aware of the »autosave« mechanism, which also sets post revisions. So leaving a tab open for 1 hour with a Post Revision interval of 6minutes and a Revision limit of 10 revisions, might destroy your whole history.

4 rows in set (0.24 sec) | Every time you edit a post/page, WordPress creates timely revisions of it. Check the Firebug console for the requests that are sent at regular intervals when you are on the edit page. They are useful if you lose the post content at some point and want to get back to an earlier version of the post.

Upgrading problem
I am using a CentOs server that managed with Plesk panel. All domains have different users. I have 2 different installation of WordPress. One is installed from FTP and the other one is installed from Plesk.
WP installed from FTP cannot be updated from admin panel of WP. The error is;
> Downloading update from <
>
> Unpacking the update…
>
> Could not copy files.

> Installation Failed
WP installed from Plesk can be updated successfully from admin panel of WP. So I check the permissions and file ownership and did the same as WP installed from Plesk. But it doesn't fix the issue.
Any suggestion?

Is there a maximum number of author for a blog?
I am building a WP blog which will feature the work of many artists and I would like to show, for each post, the artist bio.
Since it is possible for an artist to have many posts over time on the blog, I don't want to insert the bio info directly inside the post and instead use a custom function to show it. This is why I was thinking about using the author meta data to store the info about the artist.
Doing this brings 2 questions:
1. is there a hard limit to the number of authors (or reason not have a lot of authors)
2. is there a reason not to do it this way? (or a better way to do it) | 1. You can have as many authors as you'd like.
2. If the artists are not the authors of the blog posts, I would consider using a custom taxonomy instead, because it would be a more accurate model.

Use safety filters even if after applied intval?
I have some values to save into postmeta and usermeta table. Before save, I already done this: `$value = intval($value)` . I think this is enough. But I see some plugins still use filters on those numbers. I want to make sure that I can do with `intval` and without safety filter. | `intval()` behaves sometimes a little bit counter-intuitive when then value has leading zeros or when it is a mathematic expression. The result should always be **safe** , but is not always what you might **expect**.
A simple example:
intval( '9223372036854775808' );
will never return this value, because even 64 bit system cannot handle such a large number. You get `9223372036854775807` on a 64 bit system and `2147483647` on 32 bit.
But if you use:
preg_match( '~\d+~', '9223372036854775808', $matches );
`$matches[0]` will return this number unchanged.

Resetting Themes Folder to Default
I recently unzipped a folder into my themes directory. However unlike other themes this one was not contained in a top-level folder. So it just dumped about 50 files directly into the themes folder.
Is there a way I can effectively reset the themes folder so I don't have all these excess files?
Otherwise I'm considering a fresh install. | Short answer: No, WordPress does not manage your theme directory, and there is no reset function.
There are two important points you should learn from that experience:
1. Always test new software (themes and plugins) in a local installation. Do not just upload something you have not tested before.
2. You could manage the directory or your whole installation with a version control software like Git or Mercurial. This way, you could reset the directory content to an earlier state, it would take just one command in a terminal. And some time to learn these tools, of course. | stackexchange-wordpress | {

409 error (Conflict) when trying to insert an image into a post

Just to be clear - the error appears only when i try to **insert** the image into the page. I can upload it to Media just fine. Also, it happens with external images as well as local ones. It seems enough to have an IMG tag with something in the SRC attribute for this to happen.

Why cant you place the Loop outside of the index.php?
This may sound like a stupid / noob question. But I'm curious to wonder as to why you can't insert the wordpress php loop functions outside into say a blog.php file but you can in a index.php file?

However, when I move the loop php code into an index.php file the blog page will then display the pages.
Am I missing something, or is there a way to insert the loop into a different .php file instead of the index?

Securing Admin Accounts - Username Discovery
We've had Limit Login Attempts installed for some weeks now, and the number of brute force attempts occurring on wp-admin/wp-login is pretty amazing. At first the attempts were all with the username "Admin," which doesn't exist on our site, so I considered it an annoyance but not much of a threat. However, now we're seeing lockouts occurring with other named admin user accounts and I'm completely at a loss of understanding for how the attackers are deducing the usernames of these accounts.
No content on our site is authored by anyone in particular and I can't find any other location on our site where these usernames are publicly published.
Any idea as to how usernames might be discoverable? | If you have pretty permalinks enabled WordPress will redirect all calls to `/?author=1` to the author archive with the user name, eg.: `/author/bob/`. And then the visitor will know the author name.

Is there a capability for managing plugin options?
I have an Editor user that I want to let use a plugin's options without being an Administrator.
I can use $user->add_cap but can't tell if any particular capability relates to the permission to edit plugin options. The plugin in question is Redirection, if that makes a difference. | The part of the capability is the job of the developers of the plugin. But normaly use the most plugins for manage options the object `manage_options`.
But if you will, that your editor only change the plugin options from one plugin, than is this not so easy. All options of the core check for this object and also the most plugins. But you can change the role for this object and hide the other plugin settings page and so on with the help if the plugin "Adminimize" for the role of your editor.
You can also change a rolle very easy via plugin "Members". | stackexchange-wordpress | {

How to empty wordpress custom post Database table
I have around 2000 custom posts. And 7 regular wp pages. I want to delete all those custom post without effecting the pages. I thought the easiest way would be to empty the custom post table but I dont know how to do it. I am familiar with DB operations but I dont know the schema of wp posts, so have no idea where these custom posts are located. I don't mind using a plugin to do it.
Inshort:- Just want to delete all the custom posts and their data. | I used a custom page template to delete all the post from the wordpress database. Everytime I would go to this page it would delete 300 posts.The code for the page template is:
<?php
// Get 300 custom post types pages, set the number higher if is not slow.
$mycustomposts = get_posts( array( 'post_type' => 'movies', 'numberposts' => 300));
echo '<pre>';
print_r($mycustomposts);
echo '</pre>';
foreach( $mycustomposts as $mypost ) {
// Delete's each post.
wp_delete_post( $mypost->ID, true);
// Set to False if you want to send them to Trash.
}
echo '<h1 style=:"color:red;"> DELETED! DELETED! DELETED! DELETED! </h1>';
// 300 custom post types are being deleted everytime you refresh the page.?> | stackexchange-wordpress | {

Disable wordpress pagination URL rewrite for specific page
I'm hoping somebody could help me out with the following issue. I have a wordpress page: < and there is a list of jobs coming from behance.net via JavaScript. When you click on "Next Page" or a specific page number, the URL is supposed to be as follows: /design-jobs/?callback=Joblist.search.repage&page=2&sort=published_date&status=current
However, WordPress automatically takes the "page=2" and rewrites the URL as
/design-jobs/2/?callback=Joblist.search.repage&sort=published_date&status=current
(I was unable to post more than two URLs hence the shortened version). Notice the number 2 is now out of the query string and "page=2" was removed as well. This then breaks the pagination of the job listing on this page.
I was wondering if there is a way to disable this rewrite behavior for a specific page to allow the pagination to work correctly. | The `redirect_canonical` filter is responsible for this, which you can selectively disable depending on the requested page. This is untested, but should work:
function wpa66273_disable_canonical_redirect( $query ) {
if( 'design-jobs' == $query->query_vars['pagename'] )
remove_filter( 'template_redirect', 'redirect_canonical' );
}

wordpress pagination fix after the_posts
I am using the_posts action to filter out some unwanted posts - this works fine, but the pagination after this is applied gets broken. If for example there is a page with 10 results before the_posts is applied, then after it gets applied the page displays only 6 posts for example, yet there is 100 posts in total and 20 of them should be excluded.
Pagination shows 1-10 pages when it should show 1-8.
So the question is - how to make pagination work as expected and display 10 posts per page and not to have pages with less than that. | Instead of using `the_posts` filter, you should try `pre_get_posts` action. | stackexchange-wordpress | {

Is it possible to use line break in theme description?
I want to give linebreak on Wordpress theme's description in `style.css` (the one in here):
/*
Theme Name:
Theme URI:
Description:
Author:
Author URI:
Version:
Tags:
*/
But it appears the formatting doesn't allow any linebreak. When I tried writing on the line below it, the text won't appear. I tried adding `/n` as a mean to add linebreak, but the `/n/` wasn't read as linebreak.
Is it not possible to add linebreaks in Wordpress theme's description? I think linebreaks may be useful when theme designer wants to outline something in points/bullets (what I've been trying; that is I want to outline several features of the theme). | > Is it not possible to add linebreaks in Wordpress theme's description?

Should a child theme share the same theme options row as the parent, or should it have it's own options row?
I'm developing a theme which uses the NHP Theme Options Framework to add some theme options. Naturally, the theme options framework creates a single row in the database to store the theme's options into.
If I create a child theme of the parent, it shares the same theme options as the parent, which leads me to my question:
Should a child theme share the same theme options row as the parent, or should it have it's own options row? Is there a reason why one would be better than the other?
If they are shared and you switched between the two themes, your options would be intact. This can be great if that was the intended behavior. On the other hand, you might go to great lengths to customize the child theme thinking it's independent, switch back to the parent and find your changes overridden. I'm having a hard time choosing one over the other. What are your thoughts? | Neither.
Theme options should be stored as theme mods, using `get_theme_mod` and `set_theme_mod`.
Internally these map on to options, but it is the official way to store theme specific options, that way when you change themes you don't get clashes, and your settings are preserved for if you ever change back. It's the classic adage of _"someone else solved that problem for me, it's their problem now"_
But should you persist in using options, I would advise you prefix all your options with your theme name, and not to share options between child and parent. Setting a child themes options should not affect a site when moving back to a parent theme.
There may be cases when it is advantageous though, so exercise good judgement ( aka use `set/get_theme_mod` )

Stop WordPress from showing images on non post pages
With regards to how WP displays "preview" text on the home page, category page etc for each post, how do you stop it from including images in this section.
I'm not talking about the featured image for each post, I'm talking about if the post has any included images within the post - I don't want them to show up in the preview text.
This is the code that outputs the content for example..
<?php the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'twentyeleven' ) ); ?> | Place following code to your theme `functions.php`:
add_filter('the_content','wpi_image_content_filter',11);
function wpi_image_content_filter($content){
if (is_home() || is_front_page()){
$content = preg_replace("/<img[^>]+\>/i", "", $content);
}
return $content;

How does one suppress a 404 status code in a WordPress page?
I've got a WordPress site that includes pages pulled from a different database. The problem is that these other pages return a 404 status code. (The WordPress posts/pages are fine.)
The 404'ed pages display fine, and I removed the "Page not Found" text from the title tag in WordPress. But Googlebot and W3C see the 404 header.
So: wow does one tell Apache to suppress a 404 status? And will Apache override WordPress's 404 header?
Does that make sense? What other info and things should I be looking at?
Can I suppress the status code in .htaccess so I don't change WP core files? | You can either add custom rewrites to your pages. Or on the top of the template files that wrap your other pages just output `header('HTTP/1.1 200 OK');`. | stackexchange-wordpress | {

How to add element after every post in the loop, but not the last one
I have a pretty common loop:
global $wp_query, $wpdb;
if ( have_posts() )
{

{
the_post();
get_template_part(
'template_parts/content'
,get_post_format()
);
}
}
else
{
get_template_part( 'no_results' );
}

How would I determine if I currently got the second to last post in the current loop?

Using wp_editor in shortcode
I am building a plugin for frontend submission. I am using shortcodes API to display the form for content submission, but I am having troubles. The problem is, wp_editor echoe's data, and shortcode should return data. When I integrate wp_editor like this:
$final_form .= wp_editor();
form does render, but not in the place but on top of the post content, where shotcode is included. Do you have any idea how would one use wp_editor in shortcode API? I don't wan't to bother with manually calling TinyMCE etc.
Thank you. | If a function `echo`s data, you can use php output buffering to capture the `echo`ed output and return it instead

// Echo the editor to the buffer
wp_editor();
// Store the contents of the buffer in a variable
$editor_contents = ob_get_clean();
// Return the content you want to the calling function

any help will be appreciated | Wordpress hardcodes the domain into many of its permalinks in the database.
An easy solution is to download an SQL dump of the database on your host using phpMyAdmin or an SQL client, and then opening the SQL file in a (robust) text editor, assuming your database isn't enormous.
Then run a Find / Replace for the old domain (localhost) and replace with the new domain, and save the file. Then you'll need to execute the new SQL file on the database, so it is replaced with the same database with the proper domains in the permalinks | stackexchange-wordpress | {
