Disable auto hide of the login form on Woocommerce's checkout page
I'm in the process of trying to style a checkout page in Woocommerce and need the login form to be visible all the time when the user is not logged in rather than initially hidden then toggled on and off.
What I have discovered is that the login form is generated by Woocommerce's `woocommerce_login_form` function and then hidden on document load by `checkout.js` on line 83 `$('p.password, form.login, .checkout_coupon, div.shipping_address').hide();`. Since this is a core file of Woocommerce and will be overwritten on update I don't want to edit that one line of code but I cannot seem to find any better way of preventing it from hiding the login form. Since this occurs after my own Javascript files I cannot even simply show the form again.
Are there any better ways I can try and prevent the form from being hidden? | If you use a custom theme, you can create your own `shop/form-login.php`, and Woocommerce will use that. Then you can change the class names or add custom JavaScript. Upgrades for the core are still possible. | stackexchange-wordpress | {

Mamp pro permalink issues. Pages keep reverting to index.php
So I pulled a site down to my local machine to do some work on it. Copied the files, find/replace on the database to update the url, added a host. Everything worked fine until I changed the permalink settings. Now every page uses the index.php template in my theme folder instead of the page.php. Of course it works fine when you use the default settings, but not any others that require htaccess directives. I have tried everything I can think of including changing the AllowOverride None to All in the httpd.conf.
Anyone else have any ideas? I am at a complete and frustrated loss.
Edit: Here is my htaccess file:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress | Okay. I got it working now. Turns out it was one or both of my custom taxonomies I had added on with my custom content type. I knew it had to do with my custom content types or taxonomies because, if I took them out and reset the permalinks, everything worked fine.
The names for these two taxonomies where type and year. I simply changed the names to media_type and media_year and everything is humming along just fine now. I guess Wordpress uses certain names and you have to be careful what you use because it can break everything. | stackexchange-wordpress | {

Exclude category
I want to exclude a category from showing in a function, but cannot figure out how to do it for my specific code as below. I want to make it so that any post that is in the "featured" category, does not display - but all other posts do.
$args = array( 'posts_per_page' => 4, 'category_name' => 'featured');
$last_5_posts_query = new WP_Query( $args );
while($last_5_posts_query->have_posts()) :
I just cannot figure out where or how to add the exclude operator, which i assume is by adding a - somewhere. Thanks. | To exclude a category, you need to know its ID. You can then exclude it like this (please not the minus before the ID):

Placeholders in Jetpack Contact Form
In HTML5 you can use placeholders in your forms to name fields or guide the users. I would like to use this in Jetpack forms but it seems it doesn't support it. You can add a default value like `default="Your name"`, but the user will then have to delete this text before writing. With placeholders the field is cleared when you start writing.
Any workarounds in JavaScript maybe? | You can do this by means of jQuery (which means this is rather a jQuery/JavaScript question).
Put the following in one of your (already included) JS files, or create a new JS file and enqueue it, or hard-code it in between `<script>...</script>` tags:

month name translation

date_i18n( 'Y. F j.', strtotime( get_the_time( "Y-m-d" ) ) );

> If the locale specifies the locale month and weekday, then the locale will take over the format for the date. If it isn't, then the date format string will be used instead.

Add user settings to specific roles

Echo Messages By Checking current_time()

How to query wp_postmeta table for any specific meta_value?

Is there a limit to the number of options you can store in one settings field of wp_options?
I have a theme with an options page. And on that page there are 1083 options. I've noticed that the last 13 are not saving. They _were_ saving at one point, but after I added new options above them, they stopped working.
I suspected that I may have run up against some kind of option limit or limit on the array so to test that, I removed 7 options above the last 13 and sure enough 7 of them saved after that.
I've been trying to find information about this but have been unable to do so. Does anyone know if you can only have 1070 options in one settings field? It's not an issue with the database longtext memory limit. These are simple 1's and 0's and hex color values and other CSS type stuff. The export of the field is only 33k. | The limit is probably not WordPress specific, but caused by PHP.
`max_input_vars` might be set to 1000, so not all fields might reach WordPress.
You can store 4,294,967,295 or 4GB (232 – 1) characters in one option, so I don’t think this is your problem. If it is, you should consider a separate table. | stackexchange-wordpress | {

Can't Auto-Update, but permissions are good?
Normally wordpress will auto-update fine without a fuss, but now throws the old ftp credentials form up in my grill.
I haven't changed any permissions in between updates, even running `chmod` and `chown` recursively to be sure, but still wordpress wants the ftp.
Out of the few wordpress installations i run, this is the only one playing hard-to-update.
I'll resort to a manual update if i have to and hope it fixes itself, but it'd be great to know what's the beef. | If you're pretty sure about that the file owner of wordpress folder is as same as that one who runs apache. (use `ps aux|grep 'httpd'` or `ps aux|grep 'apache'`)

return $method;
}

**Why Would Wordpress Request FTP Credentials**

Here is the code:
if( getmyuid() == @fileowner($temp_file_name) )
$method = 'direct';

Get Product id from order id in Woocommerce
I am having trouble with Woocommerce product details and order details relationship. I'm not able to find the product ID of a related order ID on the _View Orders_ page of the Woocommerce theme. I simply want to get the product content and permalink etc on _View Orders_ page.
I tried searching in `wp_postmeta` but had no luck. | ## WooCommerce 3.0+
you can get the order items of an order by
$order = wc_get_order( $order_id );

$product_variation_id = $item->get_variation_id();

$order = new WC_Order( $order_id );
$items = $order->get_items();
foreach ( $items as $item ) {

(C) Again, On this lightbox there would be a submit button. On clicking this form needs to be submitted with selected checkboxes values.
The lightbox will work as confirmation window, Any help much appriciated.!enter image description here | Before anything... to get a good answer, you need to provide a good question. Code examples would help a lot.
You can use jQuery to accomplish what you need.
Suppose your checkboxes are in a list.
1. You can assign an ID to the list UL.
2. You can use jQuery to run through every element in that list and see if the checkboxes are checked
$("#checked li:checkbox").each(function(){
if($(this).is(':checked')){
//from here you can put the results found in an array,
// or just append to a hidden div that you can target with the lightbox plugin you're using.
}
});
The idea is to build a hidden DIV that you can use to open as a lightbox. The submit button would have to trigger your form to submit the data to either a table you created in your database, or add it to an existing wordpress table.

I can't change the body background-color through style.css

body.custom-background { background-color: #e6e6e6; }

Using page-id-{ID} from body_class() in local dev, versus live staging

Which worked, but it only displayed the first 4 posts. So I wanted to display all the posts from the category, as well as change the posts per page limit, as well as set the orderby for good measure. However, this query returns EVERY post on my site, regardless of category:
<?php $page_query = new WP_Query('post_type=post&cat=145'. '&posts_per_page=-1&cat' . '&orderby=date&order=asc'); ?>

How to loop through custom posts in admin edit screen

How to include custom field in shortcode (do_shortcode) in theme file

query_posts('cat=2&showposts=5'.'&orderby=date&order=desc');
while (have_posts()) : the_post();
the_content();
endwhile;

I've tried to do this but somehow my page breaks down saying that my server is configured incorrectly. | Without seeing the broken code it is hard to say, but your filter should look something like this:

$qry->set('cat',2);

"set_front" => false on custom post type breaks wp_list_categories links
My question is related to this one. I would like my post permalinks to be prefixed by `/blog/`, but I don't want this prefix to be applied to my custom post type _portfolio_. In other words, I expect post links to use `/blog/` and portfolio links to use `/portfolio/`. This is why I set `set_front` to `false` for this post type and set my permalink structure to `/blog/%postname%/`.
This almost works, except that a `wp_list_categories` call in my page header prints broken links. My skill taxonomy links have the form `/portfolio/[SKILLNAME]`, but this function is outputting `/blog/portfolio/[SKILLNAME]`, which leads to a 404 page.
Any thoughts on what might be going on here? I already tried clicking _Save changes_ on the Permalinks settings page to force a flush of the rewrite rules. | The parameter you are using is wrong. There is no `set_front` parameter when you register a Custom Post Type. The appropriate parameter is `with_front`.

How to increase maximum number of sidebars support?
How can i use more than 20 sidebars in wordpress. I'm working on a big information portal, and I need big amaunt of sidebars (about 40, I guess).

Number of displayed posts
I have tried many things to solve this problem.
So I have a plugin which displays projects assigned to users in a widget. It displays projects as posts. The problem is that it only displays `5` projects on the page.
I am sending a code which display posts:
$projects = get_posts(array('post_type' => 'projects'));
One guy told me to change it to
$projects = get_posts(array('post_type' => 'projects', 'number posts' => 10));
which should help but it didnt.
Anyone have idea how to solve it ? I can send whole code if it's needed. | The WordPress function `get_posts()` supports:

instead of
$projects = get_posts(array('post_type' => 'projects', 'number posts' => 10));

How to modify category.php to list posts alphabetically?
As the title says. Would be grateful for your help. Thank you. | Try to do all theme modifications in functions.php whenever possible. It keeps the theme files clean and uncluttered. Here's an example using the `pre_get_posts` action:

}
}

Set default text for the editor in new posts

*
* @param string $content
* @param object $post

{
if ( '' !== $content or 'post' !== $post->post_type )
{
return $content;
}
return 'This is the <em>default</em> content. You may customize it.';
}
As you can see, the post type is already available, so you could set different defaults for different post types.

Transient unique names

Unregister Nav Menu with fallback?

Are Post IDs Unique Across all Post Types?

Resetting menu_order to 0 for posts in PHPmyAdmin?

Thanks | WP search is rather simplistic. After some processing on search query, it adds condition to SQL query looking for `LIKE` (contains) match in title or post content.

Is there a quick way to view the wp-cron schedule

preg_replace and comment_form_defaults
this was kinda of a joke at the beginning but now I'm wondering if it's possible to use regex with the hook comment_form_defaults. Here is what I'm looking for :
function remove_default_allowed_tags( $defaults) {
$defaults = preg_replace('/<p class="form-allowed-tags">(.*?)<\/p>/','', $defaults);
return $defaults;
}
add_filter('comment_form_defaults', 'remove_default_allowed_tags', 2);
I know it can be easily done with something like this : `$defaults['comment_notes_after'] = ''; return $defaults;`
But I just want to know if I can use my regex in this context and if not, why. Thanks for your answer(s). | You can use regex anywhere you have a string to manipulate. That is basic PHP. There is nothing special about WordPress that changes that.
But why use regex when there are other options? As much fun as it is, regex is tricky and easy to get wrong, and there is significant overhead to using it.
What you are doing generates an "array to string conversion" `Notice`, by the way. `preg_replace` will accept an array of strings as the third parameter but `$defaults['fields']` is an array so you get an `Notice` so it wouldn't work as expected if you tried to alter that field. | stackexchange-wordpress | {

Video uploaded with the native media uploader gives Error 404
I created a `shortcode` to make an HTML5 player insert into my post, but my problem is when I attempt to view a video that I've uploaded with the native `Media Uploader`, I get a file not found error. The test video I used is an `.mp4`.
Is there a block on using videos in the `Media Uploader` that needs to get removed?

Are links allowed in the Upgrade Notice section of a plugin's readme.txt file?

Adding a gallery to my first theme

How do I avoid having duplicate of plugin in trunk?
I published a plugin and then installed it into a test site to check it was published OK.
The copy that was installed contains:
* plugin.php
* readme.txt
* trunk/plugin.php
* trunk/readme.txt
The trunk folder is redundant and other plugins don't seem to come duplicated. How can I avoid the plugin files getting downloaded twice? | I do not know which OS and/or software you use but regarding SVN it's quite simple :
$ svn co

Featured image for news page
Is it possible to display a featured image on a news page that uses index.php?
I'm currently using wp_query to display posts from a specific category on the news page. Each post has his own featured image which isn't displayed on the index/news page but only for the post itself.
If i place `<?php the_post_thumbnail();? >` before the query it displays all featured images for the posts shown on the news page but not the featured image which I've setup for the news page itself.
How can I solve this? If it's even possible as the codex says that the featured image is only for post and pages. The news page is a page but uses index.php instead of page.php. | If I am reading your question correctly, the problem is that when you set a page so that it has a an archive Loop on it `$wp_query` and the `$posts` variable are set to for the index Loop and not for the page the are on. To get information about that page you need `get_queried_object`. Two lines will show your featured image.
$obj = get_queried_object();
echo get_the_post_thumbnail($obj->ID);
One line if your PHP is recent enough
echo get_the_post_thumbnail(get_queried_object()->ID);
Obviously you will want to do something a bit more complicated to check for errors and avoid notices, but basically that is it.
Be careful with `get_queried_object`. It returns very different information depending on the type of page you are on-- index, single, author archive, tab archive, etc. | stackexchange-wordpress | {

Insert data in custom table during new post creation
I want to in insert data in my custom db table when creating a post.
Suppose there are three categories (php, wordpress & jquery). When i create a post in wordpress, i want to insert post id and category id in my custom database table. How can i do this job? | You hook a function to `save_post` (for saves and updates) or `publish_post` for publication only. The second hook is really a variable hook of the form `{$new_status}_{$post->post_type}` so it will be different if you aren't dealing with a `post` post type.
function do_on_publish_wpse_98177($id) {
// your code; $id is the post ID
}
add_action('publish_post','do_on_publish_wpse_98177');
Make backups and test thoroughly on a development server. It is easy to break things with these hooks.
You can use `$id` to pull information from the database including category information. You can also access the `global` `$_POST` if you need it but these hooks run after the post save so if something has altered (another function) the data saved to the database `$_POST` might be out of sync.

Why my plugins are updating automatically?
I have a wordpress site with a few plugins. I had to make some custom changes on a plugin (not a best practice), and of course I don't want to update that plugin.
But for some reason all my plugins have been updating themselves automatically without asking. ( Is that even possible ?!!). I have never had this behavior before.
I know that some plugins will show a notification whenever a new version is available and then I must click to update it.
My question is: **Is it possible that my plugins are updating without asking?** or perhaps this could be a security issue and I might have an unwanted admin updating the plugins ?
\-- Edit --
I think I found my problem. I posted the answer. Thanks for all the others answers, they helped me to rule out other possibilities. | I found my problem:
Once I have updated a plugin through the wordpress admin section once, it will continue to update it automatically whenever there is a new version of this plugin. I didn't know this behavior.

Using one slug/post-name for multiple pages

foo.com/bar/page
foo.com/barz/page // Will not work. Instead it will use page-2.
I've done some research and it doesn't look like it's possible to do what I want. Before I give up on trying to get the url structure to work like I would like, I figured I would reach out to the WordPress community to see if anything has changed in a newer release to allow this behavior. I'd really like to avoid using `%post_id%` at all costs because I don't think it looks very nice in the url. | This is not natively possible, since in your example permalink structure posts are detected by slug alone, and not combination with category. Essentially category info gets simply discarded.
If your requirements involve only one (few) of possible endings for URL you might achieve this _relatively_ easy using endpoints, see `add_rewrite_endpoint()`.

Enable Minify in W3Total Cache using NGINX
I am having an issue with enabling minify with the W3TC plugin. I am using a LEMP stack and cloudfront as a CDN, and all of these features, except for the minify work fine. In order to enable fancy permaplinks in WP I added `/index.php?q=$uri&$args` to the `try_files` line in sites-available and now all of the permalinks are `/index.php/postname/` which I think may have something to do with these errors. | Try using the following for your rewrite rules:
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
Using that schema, you can manually remove `index.php` from your Permalinks settings without breaking anything. Nginx will now check any URI for its existence as a file on the filesystem, and then a directory on the filesystem, and if neither of those return a valid entry it hands off the entire URI to index.php to process, complete with any query strings if any are present.
