Posts not working on windows after changing permalinks
I recently started learning wordpress. Out to curiosity of changing settings, I changed permalinks to Month and Name. After that all my posts and pages have stopped working and show me a 404 Error. I am not being able to figure out why is it happening.
I even tried posting new posts and even they doesnt work.
Please suggest any solution. I am using WP 3.7 on windows machine with wamp. | In wamp you have to manually click/unclick an option to change the .htaccess(and allow permalinks with that).
To do this , click the wamp icon on your (windows) task bar, choose apache > apache modules and check 'rewrite module' | stackexchange-wordpress | {

Getting a user role from the user login name
The question might be simple. Since I need to fix it soon I had to ask.
Currently I am modifying a free plugin. In that I am having the _user login_ string.
How can I get the role for that login?
I'm using WordPress 3.8. | You'll want to use `get_user_by()`, which will return a `WP_USER` object which contains roles and capabilities. More info here.

Passing User_Fields to Contact form 7
I'm trying to pass some custom field data to contact form 7 - The billing address and name and email address.
I've created a function that pulls in these details from the database - is there an easy way I can send these details in an email when a forms sent?
Can I possible somehow pass the data to the form sending template.

Home links redirects to old site
So I have a issue that can´t really wrap my head around, it is most likely .htaccess related. I have just moved my site from a subdirectory to the main directory, this was done changing the site url and the url of the sitebuilder. The new site works fine, but the links to example.se redirects to < this is the way the old site was set up. Now I wonder how to stop this from happening, where I unfortunately removed the old site including its htaccess file. | First back up your database. It is always wise to do that before doing anything. Now download and install Velvet Blues Update URLs plugin. Enter your old URL (like < and new URL (like < and select all options and click Update.

search does not yield access restricted results
If the user is logged out and tries to search something, he is redirected to the login page. How is it possible to have the search always show all of the results (including the excerpts and the image), even if the user is logged out and the resulting pages/posts are restricted to members only?

$query->set( 'post_status', array ( 'publish', 'private' ) );

How can I add a column/s to wp_posts table?
I am trying to sync WP with another service that offers an API that allows me to hook up their table's Update, Create, Delete to my sites.
So when they create, update, or delete a row on their server, I get details about that update, including the row ID.
The way I am thinking of syncing is by using custom post types, and either add a new separate table with post -> api relation like `post_id:1 = api_id:53`.
Or alter `wp_posts` table by adding a column containing the api_id.
I know I can add metabox which will add that as post_meta but I am not sure how effective will that be and I am pretty sure if I alter `wp_posts`, querying will be a lot faster.
So how can I alter `wp_posts` in the WordPress way? If that's not possible, should I add meta boxes or create an entirely new table just for the relation ? | You can technically add a post column with SQL but I'd caution against it as backup scripts, exports etc. would likely ignore it.
Instead, I would add the content as a post_meta, either using a Custom Field or through PHP with the update_post_meta() function.
To fetch a post based on the meta simply use:
$args = array(
'post_type' => 'custom_post_type',
'meta_key' => 'api',
'meta_value' => $api_value,
);
$posts = get_posts( $args )

How can I create blog specific database table in multisite?
I am creating a plugin, that supposed to work on WP multisite yesterday. I've installed WP multisite on my server. While testing I found out that `register_activation_hook` created 1 table on the main blog only, while I have 2 more blogs.

require_once(ABSPATH . 'wp-admin/includes/upgrade.php');

ID bigint(20) NOT NULL AUTO_INCREMENT,
service_id bigint(20) NOT NULL,
name varchar(200) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
UNIQUE KEY cuunique (`ID`)
);";
dbDelta($table);
Is there a way to creating this table for every blog on the network upon activation ? | The basic process - on activation, check if `is_multisite`, get all of the sites with `wp_get_sites`, loop over the results with `foreach` and `switch_to_blog` for each site ID, and create the table.
You'll also need to hook the `wpmu_new_blog` action, check if `is_plugin_active_for_network`, switch to that blog ID and run your activation code, so sites added after activation have their table created.

Letting users create a post that is a custom post type from a page
I'm trying to create a kind of "Request for Proposals" system for a blog that belongs to a client of mine.
I'm not too sure how to go about this, but so far I've outlined this much..

Proposers will be able to submit their proposals from the front-end of the site.
Speculators will be able to login and see the page that lists all the most recent proposals, as well as view them individually. Speculators should be the only role allowed to do this.

SEO implications of assigning a new domain to a multisite subdomain
I run Wordpress in Network mode (subdomain), and I have built up a good page rank for one of my subdomain sites.
If I register a proper domain name for my network subdomain site, and use the domain mapping plugin to take it from a subdomain of the first site, to being a new domain, does Wordpress do a 301 redirect from the subdomain of the first site to my new domain?
Thanks. | In the "Domain Mapping" section of the WordPress MU Domain Mapping plugin (found under Settings in Network Admin), there is a check box to turn on and off the "Permanent Redirect", which is a 301 permanent redirect.

So strange result of wp_query and have_posts

}
echo 'End: "' . $have_posts . '"'; // false -> I think false is right.
echo 'End: "' . $featured_posts->have_posts() . '"'; // but still TRUE, WHY?
Am I missing anything? | If we look at `have_posts()` in source, we can see why this happens:

Pull Custom /wp-admin/css for Non-Admin in Multisite
Here's a problem I'm sure many would like to find an answer to...

Is there a way to pull a custom /wp-admin/css/ folder for all site users other than the site owner?

Custom Post Type Posts Not Showing Up in Admin

Now in the admin panel of "Gig," it says "No Gigs Found" Even if above the post list it says there are 17 published posts. How could I make the published posts show up again? | When you fiddled, it's possible that your custom posts were created with your "Shows" post type, not "Gig".
You could check that in the database directly using PHPMyAdmin or whichever tool your host offers.
In PHPMyAdmin look for your wp_posts (the wp_ could be different) and look at all of the posts probably clicking on the ID column to sort the newest to the top, then scroll to the right and look for the post_type column of a row that contains one of your test posts.
It's not ideal, but you can now delete those posts (you should also find the posts_meta for them), or change the post_type column. Or just leave them alone and they shouldn't cause you any trouble.

Specifying a size when displaying an image associated with a taxonomy through ACF
I created a "books" custom taxonomy for my "book" CPT. Using ACF, I assigned an image to each my custom taxonomy terms.

}
?>

I think the ACF doc page about images contains the key to what I'm trying to do - especially the part about image size, but I can't seem to find a way to integrate it to my code successfully. Any suggestion? | It appears you currently have the field set to return the image object, if you scroll down to the bottom of the page you linked you'll see an example object:

WP_Query Limit Data_Query last 90 days
I want to perform a `WP_Query` that finds all posts limited to the last 90 days. From my understanding, WP_Query accepts numerical values for months, years, days, etc, but I'm not sure I understand how to pass an argument that says "get all posts from 90 days ago until today."
I'm guessing I have to get the current time and then subtract 90 days from that, but it looks like the "day" argument is relative to the month (i.e. 1-31). There is no way to compare timestamps?
This is sort of what I have so far -
$today = getdate();
'date_query' => array(
array(
'day' => array( $today["day"], $today["day"] - 90 ),
'compare' => 'BETWEEN',
)
) | In order to query posts with a `date_query`, you can pass the argument of column `post_date_gmt` which is the date the post was published, and then pass the argument of `before/after` and a string to represent your request. So for published posts from now until 90 days ago, you would put this in your `WP_Query` args:
'date_query' => array(
array(
'column' => 'post_date_gmt',
'after' => '90 days ago',
)
)
This says get me all posts from 90 days ago and AFTER, which would stop at present time.
You could pass the string `3 months ago`, `1 year ago`, etc. It basically takes on the same behavior of `strtotime()`. | stackexchange-wordpress | {

What hook can I use to modify custom post data before it is displayed on the page?
I need to check if a certain value is true in the post_meta right after the wp fetches a custom post from database, If it's false I need to modify/add some data to the post and then display the modified version, if it's true it should continue as usual. What would be the best hook and approach in general to accomplish something like this?
Edit: Forgot to mention before, but I would HIGHLY prefer to do this inside a plugin. | You can use `the_content` filter to modify content before it's output.

WPSC how do i output product per category on one page (wpsc-product-page)

Any tips, suggestions? | You need to do 2 queries, 1 for the terms (using get_terms) and then a post query, an example is:
$taxonomy = 'portfolio_types';
$tax_terms = get_terms($taxonomy);
foreach ($tax_terms as $tax_term) {
echo '<li>' . '<a href="#'.$tax_term->slug.'"' . '>' . $tax_term->name.'</a></li>';
}
endwhile; endif;

$the_query = new WP_Query( 'post_type=portfolio&portfolio_types='$taxonomy );
while ( $the_query->have_posts() ) :
$the_query->the_post();
the_title();
endwhile;
You will need to change the post_type and the taxonomy to yours (not tested though)
Basically what the script does is find all the taxonomy terms, and when it finds one it looks for any posts under that term. | stackexchange-wordpress | {

Order get_users() by last login date. Is it possible?
I want to create a page that displays all the blog users ordered by the last login date.
I've tried with the get_users() function and I can succesfully get the users' list, but not in the order I want:
$query = get_users('&offset='.$offset.'&orderby=login&order=DESC&number='.$number);
I think that the orderby=login is not what I'm looking for... Is there any other way to accomplish this? | First, you need to store the actual login date, because this is not stored by default. You can use this code to do that(use it in your functions.php)

$user = get_user_by('login',$login);
$now = time();
update_usermeta( $user->ID, 'user_last_login', $now );

Add feed to a custom page
I have searched and found a lot of people asking about how to add a custom rss feed for custom post types/taxonomies. However that's not the problem right now.

ACF: Display category name using taxonomy field

Return category posts with WP_Query
I have a some categories and want to get the posts with those categories:
$temp = $wp_query; // assign ordinal query to temp variable for later use
$wp_query = null;
$wp_query = new WP_Query('cat=85');
if($wp_query->have_posts()) {
...
}
But it is not entering in the `if` condition. The category with `id=85` exists and some posts are using it. So I don't understand why it is not returning any post.
Any idea. Am I doing something wrong? | By default `WP_Query` will return only the `post` post type. To retrieve other post types, you need to add a `post_type` argument. Using `any` will return results from all public, registered post types.
$my_query = new WP_Query(
array(
'cat' => 1,
'post_type' => 'any'
)
);
var_dump($my_query->request); // debug; allows you to see the SQL
if($my_query->have_posts()) {
// ..
}
If you only want a particular post type, just use the post type's slug, or you can use an array of post type slugs to get returns from multiple particular post types.
Also, there is rarely a good reason to clobber `$wp_query`, even if you save it to put it back later. | stackexchange-wordpress | {

Is there a filter for get_post_custom()?

How to insert more than one row of data into a table at one time

'point_one' => '0.27',
'point_two' => '0.17'

Retrieving a JSON feed of my posts and displaying thumbnails
I want to show a feed of my latest posts though json.
I seem to be able to do it - up to a point. I am retrieving my feed like so:
var json = <?php echo json_encode($query->get_posts()); ?>;
Problem is, I can't retrieve the post thumbnails, I can just retreive the post title and a bunch of other information, but can't seem to get what I'm looking for. Any idea how I can do that?
Thanks a lot! | Try something like this:
$posts = $query->get_posts();
foreach($posts as $p){
$thumb_id = get_post_thumbnail_id($p->ID);
$src = wp_get_attachment_image_src($thumb_id, 'image_size');
$url = $src ? $src[0] : false;
$p->image_url = $url;
}
$json = json_encode($posts);
Now you can echo out `$json` into your JS var. You will find the image url string in the key `image_url` of your json object. You can test if there is an image by testing if the value returned is false or not.
Be sure to change `image_size` in the `wp_get_attachment_image_src()` function to the name of the image size you want.
In essence we are looping over the query, grabbing the post thumbnail and finding the url of the image we want, then we add it to the object as a new property.

How to get site homepage from plugin?

making the [...] clickable
I have created a child theme for twenty twelve.

Handle lots of images within the media uploader / selector

"the media selector freezes." Do you mean the whole browser window? Or the popup media library window?

What is the action or filter for adding information under the Permalink in Edit Post/Page?
I would like to add some HTML under the "Permalink:" in the Edit Post/Page page.
Under here:
!Under Here
So what is the action or filter? | You can try the `edit_form_after_title` action:
add_action( 'edit_form_after_title', function(){
echo '<hr/><div>My custom HTML</div><hr/>';
});
to add your custom HTML after the permalink:
!custom HTML
It will inject the HTML between `div#titlediv` and `div#postdivrich`:
<div id="post-body-content">
<div id="titlediv">...<!-- /titlediv -->
<hr><div>My custom HTML</div><hr>
<div id="postdivrich" class="postarea edit-form-section">...</div>
...
</div>
Tip: when you have question like this, best thing to do is look at source code.
The file responsible to output post edit page in admin is `/wp-admin/edit-form-advanced.php`
The hook you are looking for is **`'edit_form_after_title'`** as you can see at line #476 of that file. | stackexchange-wordpress | {

HTML Redirect to WP pages
I have some predefined links that I need to redirect to real URLs within my WP install. I have NO CHOICE but to use these URLs provided to me, unfortunately. The format is:
<

RewriteCond %{REQUEST_URI} ^/redirect.html(.*)$
RewriteCond %{QUERY_STRING} ^(.*?)&?p=page&?(.*?)$
RewriteRule (.*) /page/?%1&%2 [L,R=301]

RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^redirect\.html$ /%1 [L,R=301]

RewriteCond %{REQUEST_URI} ^/redirect.html(.*)$
RewriteCond %{QUERY_STRING} ^p=test$
RewriteRule (.*) /new-test/ [L,R=301]
RewriteCond %{REQUEST_URI} ^/redirect.html(.*)$

How can I show many posts an author has per week?

PHP Memory Limit vs. WP Memory Limit
I'm using TPC! Memory Usage Settings to monitor my installation's memory usage.
The plugin displays 'WP Memory Limit' which I know is set by the `wp-config.php`. It also displays 'PHP Memory Limit' which I'm guessing is set by the server host in the `php.ini`
This may be a dumb question, but is the 'PHP Memory Limit' the amount of memory I could possibly dedicate to 'WP Memory Limit'?
For instance, if I have a 'PHP memory limit' of `1000MB`, can I (should I) set my wp memory limit to `1000MB`?
Sidenote: The site is for a big website with lots of different operations, so many (necessary) plugins are installed and many users (up to 10) can be on making edits at any time. | `wp-config.php` sets the memory limit for the specific WordPress site which has that file. `php.ini` will effect your whole server. The `php.ini` is the parent setting, and so you can set WP to whatever you want within `php.ini`'s range.
It's also importan to note there is a `WP_MAX_MEMORY_LIMIT` where you can define a max amount of memory WP should use, especially if you have plugins gobbling up all the memory. | stackexchange-wordpress | {

Registering different Post Formats for Blog Post and CPT
I'm using following code to register post formats for my blog posts ...
add_theme_support( 'post-formats', array( 'gallery', 'video', 'audio' ) );
Now, i want to add post formats support for my CPT 'Portfolio' too, but using different set of post formats. Using this code will add post format support for my CPT ...
add_post_type_support( 'portfolio', 'post-formats' );
But i only want to register _gallery_ and _video_ post format for portfolio CPT. Using the code below does'nt work ...
add_post_type_support( 'portfolio', 'post-formats', array( 'gallery', 'video' ) );
What code should i use? | I found an alternative approach.
There is a unique class in body tag for each post type. e.g for _portfolio_ post type i can use the CSS code something like mentioned below to hide the extra option.
.post-type-portfolio #post-format-audio, /* for radio button itself */
.post-type-portfolio .post-format-audio /* for option label */
{
display: none;
}
Hope it helps anybody else. | stackexchange-wordpress | {

How To Get Parent Category Slug of Current Post
My theme has styling by category using the following code, which inserts the current category's slug as a CSS class.
<div class="CategorySpecificStyle
<?php $category = get_the_category(); echo $category[0]->slug; ?>">
<?php echo $category[0]->cat_name; ?>
</div>
Now i'm about to add a large number of new sub-categories, and it seems silly to add them all in CSS when I should be able to just select the parent category of the current post and apply styles to that.
I've been able to get the parent category's name:
$parentcat = get_cat_name($category[0]->category_parent);
But spaces (and capitalization) is an issue... And I can't seem to get the parent category's slug.
I know i'm probably missing a simple step somewhere, but any insight would be greatly appreciated. | You will need to use the ID value returned by `$category[0]->category_parent` and pass it through `get_term()`. Example:
$category = get_the_category();
$category_parent_id = $category[0]->category_parent;
if ( $category_parent_id != 0 ) {
$category_parent = get_term( $category_parent_id, 'category' );
$css_slug = $category_parent->slug;
} else {
$css_slug = $category[0]->slug;

Widget only in first post

How to change the position of Jetpack sharing icons?
!Jetpack Sharing buttons settins
Typically Jetpack sharing buttons target the single page's `the_content()` function and echo the sharing icons just below the content. But for my site, I actually want it to **Disable** for `the_content()`, but to use it in some other `<div>`. I know I can check the "Disable CSS and JS" checkbox to disable the built-in functionality, but I actually don't want to code more and I like the default CSS of Jetpack sharing icons.
I simply want a Javascript code to alter the target of Jetpack so that instead of showing under the `the_content()` I can show it under another custom `<div>` of my choice.
Is it possible with any filter or hook?
P.S.: I just renamed the "Posts" to "Products" for my project. It's nothing to worry about. :) | remove_filter( 'the_content', 'sharing_display', 19 );

function share_buttons_above_post( $content = '' ) {

Can I use Woocommerce to take orders but not handle payment?
I would like to create an ecommerce website.
In this website the customer will browse the product catalog, add the desired products to his cart, maybe create an account, and during the checkout phase, will leave a phone number along with his shipping information and address.
I will then manually review every order made (and be notified via email for new orders), call the person and handle it from then on.
Is this possible or do I have to let woocommerce handle the payments using a gateway like PayPal?
If it is possible, can someone please guide me how to set it up like so? | You can use multiple payment gateways. Simply use one of the default payment gateways that doesn't require immediately payment and you can rename it in the settings, so you have the same process that you described above.

Wordpress theme Modifications not showing up on live server

Menu not always using correct link
I moved a Wordpress install from /wordpress/ folder to root by just copying the index and .htaccess file to root and then updating the permalinks etc.
All works fine but I have a problem with the menu in the top nav.
The menu works fine while you're on the main page and scrolls down to the area it should be. But when you go to one of the posts under services like < and then press on for instance "team" in the menu it will point to < thus suddenly adding the /wordpress/ to it and ending up at a blank page.
Anyone have an idea how I can solve this? | It appears that all of the links inside that menu are custom menu links, based on the classes "menu-item-type-custom" & "menu-item-object-custom".
You should be able to go into the menu and put whatever you want in the url field.
If you are using hash links (#team) and may have to put the full url ` as opposed to `#services`
You can also double check the Settings > General > Blog/Site URL to ensure that the /wordpress sub directory is not listed there.
Though it doesn't seem that those will actually link anywhere because there is no div with that ID on the page. Where are these links supposed to go to? | stackexchange-wordpress | {
