wp_users user_status field
I have found an answer to my question here but it's 7 years old. I simply want to know if I can use this column for my own purposes.
I'm planning to use the `user_activation_key` column to store a hashed key upon user registration and set an inactive flag in the `user_status` column. This flag will prevent users from logging in until their e-mail address has been verified. | As far as I know it isn't used, but to avoid conflicts/problems, other plugins might use it, I'd go with adding a meta to the wp_usermeta table. There is a set of functions for handling that:
* add_user_meta()
* get_user_meta()
* update_user_meta()
* delete_user_meta()
Shouldn't make a big difference for the functionality you want to implement, but you're on the saver side of things. | stackexchange-wordpress | {

foreach loop displaying below content summary
I am trying to wrap my result with `<li>`, but when I do so as in the code, I get funny results, as the result display way below.
do_action( 'woocommerce_after_shop_loop_item' );
$value = get_the_terms( $product->id, 'pa_package');
foreach ( $value as $values ) {
echo "<li>";
echo $values->name;
echo "</li>";
} | You can hook into the action like this:
**Code:**
add_action( 'woocommerce_after_shop_loop_item', 'wpse124226_wc_product_attribute_list' );
function wpse124226_wc_product_attribute_list() {
$value = get_the_terms( $product->id, 'pa_package');
echo "<ul>";
foreach ( $value as $values ) {
echo "<li>";
echo $values->name;
echo "</li>";
}
echo "</ul>";
}
Take a look at the codex Plugin API to inform yourself about using hooks. BTW you can use woocommerce functions to get the attributes, especially `get_attributes`, take a look at the source at the woocommerce documentation.

Too few arguments for printf()
I'm having a problem making this printf print the time & date correctly within my theme. I keep getting "Too few arguments."
<span class="entry-date"><abbr class="published" title="<?php the_time('Y-m-d') ?>"><?php unset($previousday); printf( __( '%1$s – %2$s', 'erudite' ), the_date( '', '', '', true ) ) ?></abbr></span>
I have two strings in the printf(). %1$s and %2$s are meant to correspond to the_time and $previousday. Is:
<?php the_time('Y-m-d')?>

expects two strings; you've only offered one (`the_date()`). If you want to use two strings, you have to give it two strings.
If you want `printf()` to use `the_time()` and `$previousday`, you need to _tell_ it so:
printf( __( '%1$s – %2$s', 'erudite' ), get_the_time(), $previousday );

The Events Calendar Plugin - List View Background Colour Issue
I'm trying to look for some help, I've got a WordPress website that I'm working on.
I'm using this plugin called **The Events Calendar** , but in List View, the background keeps showing in transparency...
Would somebody be able to help me trigger and find where in the code I can change the background color instead of having it in transparency?
Here is the link: < | If I understand you correctly, you can add this code to #tribe-events-content.tribe-events-list in your stylesheet like so:
#tribe-events-content.tribe-events-list {
margin-bottom: 60px;
background: #FFFFFF; /* ADD A BACKGROUND COLOR HERE */
}
That will add a background to the Upcoming Events section so that the text is more easily readable.

Shortcode return $content vs do_shortcode($content)
I think the title of my question says it all.
When creating a shortcode, I've seen some people do `do_shortcode($content)` instead of `$content`.
What is the difference?
Another thing, let's say I have a shortcode `[hello]World[/hello]`. Wouldn't returning `do_shortcode($content)` result in `do_shortcode('World')`?
From the codex, the examples given are as such, `do_shortcode('[hello]')`
So what will returning `do_shortcode($content)` interpret? (in the case of `[hello]`)
Any practical examples or clear explanations would be greatly appreciated. Thanks. | This is useful if you don’t know if the `$content` contains unknown shortcodes.
Example
**Your shortcode**
add_shortcode( 'foo', 'shortcode_foo' );
function shortcode_foo( $atts, $content = '' )
{
return 'Foo!' . do_shortcode( $content );
}
Now your user might write something like this:
[foo][bar][/foo]
You have no idea what `[bar]` does or that it even exists. So you let WordPress handle that per `do_shortcode()`. If you don’t do that, `[bar]` will not be parsed as shortcode and showed as is instead. | stackexchange-wordpress | {

How to turn off searching from URL and go straight to 404 page
When I put something after my domain name that doesn't exist I am taken to my 404 page, for example:
example.com/sdkjhfdsjk
But if I put something that exists as an image I am taken to the page for that, for example:
example.com/imagename
How can I turn this off. I only want to be taken to pages or posts that exist.
UPDATE: This has been marked as a duplicate but the accepted answer to that does NOT fix this.
I added:
remove_action('template_redirect', 'redirect_canonical');
to my themes `functions.php` but the same action happens. | Try
function no_attachment_page() {
global $wp_query;
if ( $wp_query->is_attachment() ) {
$wp_query->set_404();
status_header(404);
nocache_headers();
}
}
add_action( 'template_redirect', 'no_attachment_page', 1 );

Get $curauth level
I am trying to get the user level of the author that is displayed on an author page (not the current user that is logged in, but the user that is presented on the current author page that I am viewing)
I am using this code
<?
get_currentuserinfo() ;
global $user_level;
if ($user_level >= 4) {
include (TEMPLATEPATH . '/author_1.php');
} else {
include (TEMPLATEPATH .'/author_2.php');
}
?>
I tried to replace $user with $curauth but still no results, it is showing only one template for both. Any ideas?
thank you | toscho is correct. User levels have been deprecated for a long time now. However, the following will get you the available information about the author of the posts on an author archive page.
$author = get_queried_object();
var_dump($author);
In that dump you should see everything you need, but use the `role` not the user level-- look in `$author->roles`. For example:
$author = get_queried_object();
$allowed = array('author','editor','administrator');
$roles = array_intersect($author->roles,$allowed);
if (!empty($roles)) {
include (TEMPLATEPATH . '/author_1.php');
} else {
include (TEMPLATEPATH .'/author_2.php');
}
You should also almost certainly be using `get_template_part` instead of `include`. | stackexchange-wordpress | {

Make a plugin work on specified domain only
I am developing a custom WP plugin for a client and I wish to make sure that the client does not install it on any other domain other than the one specified. If the client tries to install the plugin on other domains, it should throw out an exception and plugin should get deactivated or self destruct.
How can I make this happen? What is the code for this and where do I add it?
Thanks! | You could use a combination of the file content and the domain to create a unique hash.
Example:
$md5 = md5( file_get_contents( __FILE__ ) . $_SERVER['HTTP_HOST'] );
if ( 'be5d38f32a5d4a897e6c878f0c2f1b14' !== $md5 )
deactivate_plugins( plugin_basename( __FILE__ ) );
Additionally, you could check each week per remote request to your server, if the hash is registered for that domain.
But be aware, this can be changed very easily. There is just no way enforce a domain. | stackexchange-wordpress | {

How do you make your theme Child Theme-able?
I'm sorry if this is an obvious question, but I've tried looking everywhere and can't seem to find an answer.
Are WordPress themes automatically Child Theme-able? Or is there a process to make a theme ready for Child Themes? | Few things have already been discussed here I would like to add more
In order to make your theme a good parent you also need to consider in following things:
* make your functions and classes pluggable ie, wrap your theme functions with `function_exists` wrapper so that they can be overridden in child pages.

function theme_entry_date(){...}

Buddypress get data from wp_bp_groups_members table

Woocommerce: how to change 'Cart Updated' message

the correct way to use options from settings page
I'm creating a plugin in Wordpress and am a little confused how I should use settings I set in my settings page.
I used: < to create my settings page. All fine, it's saving the options into the options table. I can echo them out but the only way I can get it to do it is with:
$value = get_option('my_option_name')['my_option'];
echo $value;
This doesn't seem a very nice way of doing it to me, and Netbeans gives me a red line under the code saying it's not compatible with my version of PHP, it works but this surely isn't the way I'm supposed to echo out values from my settings page is it? | `get_option( $option )` returns an array. You need to get access to that array, and _then_ get the keys/values inside of it.
Try this instead:
$value = get_option( 'my_option_name' );

When to add_filter() to Custom Query
I have complicated query where I need to join multiple tables. I'm doing that via `add_filter('posts_join')` \- my question is, when and where do I add the filter so that it only applies to the custom query?

Should I physically add the filter above the query or after? Do I need to put it into a separate file (function.php) and attach it another way? Do I need to do something with `query_vars`? | You want to add your filter before you create the query:
add_filter( 'posts_join', 'custom_posts_join' );
$test = new WP_Query( $args );
where you can define the filter callback in your theme files, for example
`functions.php` or in a plugin:
function custom_posts_join( $join )
{
// modifications
// $join = ...
// remove the filter
remove_filter( current_filter(), __FUNCTION__ );
// return the result
return $join;
}
Notice that we remove the filter with this line:
remove_filter( current_filter(), __FUNCTION__ );

Need To Deregister Scripts Via Functions.Php
Well, I am a little disappointed how difficult Wordpress it makes to deregister scripts.
First, I got a list of all handles, so I looked it up and the handle was jquery-migrate
I then added this to my functions.php
wp_dequeue_script('jquery-migrate');
Also this
wp_dequeue_script('jquery');
It does nothing, although the scripts are properly registered.
What's up with the version strings, I can think of no reasons why they are still including those, should be removed in the next WP version asap, they only prevent caches from properly caching it in some cases and are annoying.

Function that outputs second theme url
I have a multisite and need a function (added to functions.php) that will get the template url of the second theme (probably by name or other identifier)?
Example: theme-1 (used by main site) contains function to get url of theme-2 (theme-2 is used by sub-sites)
Thanks | You can use two inbuilt functions to do this.
1. switch_to_blog
2. get_stylesheet_directory_uri
You can use both in the following way to make a function out of it which would give you the url to the theme. Put the below in the **`functions.php`** file
function wpse_get_theme_url( $blog_id = 1 ){
switch_to_blog( $blog_id );
$template_url = get_stylesheet_directory_uri();
restore_current_blog(); // Switch back to the original blog
return $template_url;
}
Now you can use the above function to fetch the url by using the function and passing the blog id/ sub site id.

I know it could be difficult to query a single item that saved in an array in wordpress postmeta table, but I have lots of metadata for a single post which may create too many rows for the postmeta table. So, I guess it might be better to save the meta in an array for each post, then, create an object to query the meta so that I can access the data by `$obj->meta1.` My question is:
1. Will it be really bothering when the postmeta table has too many rows?
2. Does saving data as array really solve my doubts? | 1. Unless you are building a heavy web application, with billions of rows ( and maybe even then ), the number of rows for MySQL is not an issue.
2. Saving your data in an array will make calling the data simpler (just one call), and keep the database smaller, but it will make parsing and searching through the data more complicated. More often than not, simple and efficient searching greatly outweighs the benefits of a smaller database. | stackexchange-wordpress | {

Modify a parent theme's PHP file, and save in child theme
I'm working with a paid theme, and we're using a child theme to display a slightly different design.
The parent theme has a file called /includes/forms/register-form.php
I'd like to customise this file, and save it in my child theme.
How do I tell Wordpress to use my child theme's version of this file, instead of my parent theme's version? | Just copy register-form.php from your parent theme and paste it under yourchildtheme/includes/forms/register-form.php , from there start changes what you want and wordpress will use that file. | stackexchange-wordpress | {

How to setup a wordpress backup in localhost?
I have a database backup and entire site folder backup of a wordpress site. I want to setup it in my localhost. These are the steps I followed.
1. Create a database
2. Import the database_backup.sql
3. Open the wp-config.php and edit the following details
> define( 'DB_NAME', 'contents_wp' );
>
> define( 'DB_USER', 'root' );
>
> define( 'DB_PASSWORD', '' );
>
> define( 'DB_HOST', '127.0.0.1' );
But I cannot log in to the admin panel. It redirects to the live site. How to solve this? What I am doing wrong here?
Any suggestions will be appreciated. | Before import database_backup.sql. You have to replace server url with your local url in sql. for example: you took backup from abc.com , and your local url is localhost/abc .then open database_backup.sql and find and replace abc.com with localhost/abc.

If custom field is empty, use one from a previous post
Let's say you have a few custom fields (I use the advanced custom fields plugin for it). There is an extra field in posts called 'afbeelding_onder'.
It is not required but on `index.php` within the loop the custom field 'afbeelding onder' from the last post will be printed. If it is possible, is there a way to check if the custom field is empty, if it isn't than it will print the value, but else (when the custom field is empty) the value of the last post which contains a value in that box will be printed.
Hope my question was clear enough, my English grammar is not that good. | if(!get_field('afbeelding_onder'))
{
$prev_post = get_previous_post();
echo '<p>' . get_field('afbeelding_onder', $prev_post->ID) . '</p>';
}

{
echo '<p>' . get_field('afbeelding_onder') . '</p>';

Should I create multiple sidebars, or use or one dynamic sidebar with logic to determine it's abilities?
I am wondering what the standard procedure for Sidebars in WordPress. My theme needs to have 3 different types of sidebars, to be used on three different pages. I am wondering if I should create a seperate sidebar for each of these pages or use logic, to determine which form it will take? As stated earlier each sidebar will have different uses for each page template it is on. | Create separate sidebars for each page unless all of them are supposed to display the same set of widgets.
I guess you will be managing your sidebar widgets through Appearance Widgets Screen (which displays all registered widgets) so just use register_sidebar() three times or preferably register_sidebars() (set _number_ to 3) within your functions.php file and then you're ready to put these in your template files:
<?php dynamic_sidebar( 'id-of-your-first-sidebar' ); ?>
<?php dynamic_sidebar( 'id-of-your-second-sidebar' ); ?>
<?php dynamic_sidebar( 'id-of-your-third-sidebar' ); ?>

How to limit the number of results for all query_posts on mysite
I have a huge number of posts and the pagination with no limits eats my server CPU and ram so I need a function to limit the number of posts for all `query_posts` on my site and I need this function to work in the admin area too if possible, any suggestions??
function limit_posts {
$args = array(
'posts_per_page' => 10,
'post_type' => 'job_listing',
);
global $wp_query;
$wp_query = new WP_Query( $args ); | It is not that hard to enforce a hard limit on results:
add_action(
'post_limits',
function($limit) {
$limits = explode(',',$limit);
if (isset($limits[1]) && 2000 < $limits['1']) {
$limits[1] = 2000;
}
$limit = implode(',',$limits);
return $limit;
}
);
I would not be surprised if that does not solve your problem though. Just searching over that many posts may be too much for your server, no matter what the limit is on the returned results.
I am also not 100% sure that that will not break things. Be careful.
You could use `'no_found_rows'=>true` for any queries that do not need pagination. That might help.
Ultimately, I suspect that you are just doing too much for your server and/or you need someone who is very, very good with server configuration to help you tweak settings and possibly load balance. | stackexchange-wordpress | {

Thanks | When you output your `get_posts` results and do this:
setup_postdata($post);
You overwrite the original value of `$post` which `the_field` uses to fetch the field data. It's trying to get that field belonging to the last post in `$products_mono_posts` instead of the page that the field actually belongs to.
After running custom queries where the value of the global `$post` is modified, you need to call `wp_reset_postdata()` to restore the value of `$post` to its original value. | stackexchange-wordpress | {

Dynamic Wordpress Admin Panel

How can I create a dynamic WP-admin panel using Wordpress?
Thanks, | WordPress admin pages are typically created using `add_menu_page()` function that takes care of menu entry and calls custom function (provided by you) to generate content of the page.

To include all the post type add the below to you arguements
$args = array( 'numberposts' => 5, 'post_type' => 'any' );
The above will include all the post_types including pages and custom post types and if you would to include specific post types use an array like

What is an "Options Framework" for Wordpress
I am exploring a couple options frameworks for wordpress like the Redux Framework. As a non-developer interested in maintaining my own Wordpress based web app, when would an options framework like Redux be useful?
Most sites for options framework market their tool to the wordpress developer community. I have not found a simple explanation geared toward non-developers or newbies that clarifies when an options framework should be used.
<
Thanks, | An options framework is designed to make the creation of settings pages for plugins and themes easier.
An options (or settings) page is a page in the WordPress Dashboard where the behavior of the theme or plugin can be controlled.
For example, themes will often have a settings page to setup color schemes, logos, and other similar options.
WordPress core (the main base software) has a system for setting up option pages, but it is a bit clunky and can be difficult for developers to get the hang of.
Option frameworks, such as Redux, aid developers in the creation of their settings pages by making it much simpler to setup the settings. | stackexchange-wordpress | {

DIR vs URI when defining a path to a file
When including files in a plugin, I've seen people do
`WP_PLUGIN_DIR.'/'.dirname(plugin_basename( **__ _FILE_ __**)).'/somefile.css'`
and yet WordPress `wp_enqueue_script/style` uses URI for the file path (such as `plugins_url`).
What difference is there? I'm confused... | When you include something, you use the file path because it's a local file and you're reading into the environment right here and now and using that code.
When you "enqueue" something, you're not reading the file in, you're sending the URL of the file to a system that puts that URL in the resulting output webpage, for the viewer's browser to then load and read.
You use a file path when the PHP code is manipulating the file. You use a URL when the browser needs to see that URL and retrieve the file itself. | stackexchange-wordpress | {

How does child theme functions.php work with parent theme functions.php? Is it like CSS?
I am looking for help on understanding how child themes and parent themes `functions.php` work.
I know with CSS, the cascade overrides CSS declared earlier in the style sheet. It is my understanding that the `functions.php` does not operate the same way. I understand that both `functions.php` are loaded.
What happens if you want to have the function in the child theme override a function in the parent theme and the parent theme is not using if statements like the codex recommends? | The comparison of CSS and `functions.php` files is pretty flawed. PHP doesn't "cascade".
To answer your question, both files are loaded, child theme `functions.php` first then the parent's.
> What happens if you want to have the function in the child theme override a function in the parent theme and the parent theme is not using if statements like the codex recommends?
You mean, if the parent function is not wrapped in `function_exists` conditional? Then you can't override the function. That is basic PHP. Try to re-declare a function and you will get an error. You can't get around that. The best you can do is hope for a filter that will let you do what you need, and contact the parent theme developer.

If I understand timing at all right, this needs to be done right after script file loaded - so that nothing else has a chance to mess up instance (it had just set up) or get messed up by it either.
However there seems to be no convention in queue functionality to echo JS at such point. `$wp_scripts->print_extra_script()` is called _before_ the script.
Is this at all possible to accomplish with current queue implementation? | # WordPress >= 4.1
WordPress 4.1 had added `script_loader_tag` filter for complete HTML of enqueued script. Perfect for the purpose of adding something _right_ after it.
* * *
## WordPress < 4.1
I ended up hooking into `wp_print_footer_scripts` at priority `11` (after queue has finished) and calling `wp_print_scripts()` explicitly on script's handle, then echoing what I needed to.
I would be hesitant to use this for something major, but for small contained script it seems acceptable. | stackexchange-wordpress | {

Comments Pagination as an unordered list
I am currently using `<?php paginate_comments_links(); ?>` to display comments pagination. How can I customise this so that it uses a UL and LI? (Such as is possible with custom post pagination).
Thanks | As paginate_comments_links() is pretty much just a already customized version for comments of paginate_links(), see the documentation for a deeper insight, you can use the parameter `type` for this.

Detect archive and category page

` \- blog category
For example, post type I can easly detect with:

> if (get_post_type( $page_id ) != 'slideshow')
How about the above pages ? I mean any category or archive page. | There are Conditional Tags for this: `is_archive()` and `is_category()` respectively. For a custom post type archives you could use `is_post_type_archive()`. There are many conditional tags available, see above linked codex page.

I've tried adding: `<img src="/home.png"/>` to the second line, still no success.
**I have tried:**
`<img src=" /><h3 class="menu-toggle"><?php _e( 'Menu', 'twentytwelve' ); ?></h3>`
Thanks | I figured it out.
You have to search your style.css file and find
`/* Buttons */`
Under that you will find the following classes
.menu-toggle,
article.post-password-required input[type=submit],
.bypostauthor cite span {}
.menu-toggle,
button,
{}
button[disabled],
input[disabled] {}
.menu-toggle:active,
.menu-toggle.toggled-on,
button:active,
{}
There are 2 states of the button that you need to configure.
Hover and active.
Just change the `background-image:url('');` for each state to what image you want in the background.
Then just either negative indent the text by -9999 or delete the text from the `header.php` file as you previously stated. | stackexchange-wordpress | {

using comments_template() in custom single-portfolio.php

How to write this conditional statement?

<a href="<?php the_permalink(); ?>" class="info"> Subscribe</a>
}else {
<a href="<?php the_permalink(); ?>" class="info">Read More</a>

Help Needed. | `is_tag` checks whether the page being displayed is the tag archive page for the named tag. It does not check whether the **_post_** in a Loop has that tag, which is what you ask: "...to show if the post has tag premium...". For that you need `has_tag`
if has_tag( 'premium' ){ ?>
<a href="<?php the_permalink(); ?>" class="info"> Subscribe</a><?php
} else { ?>
<a href="<?php the_permalink(); ?>" class="info">Read More</a><?php

Load Pages Menu in single.php

Google indexed pages for one page site
I have created a one page site with wordpress. The basic idea used was to combine pages and their templates into index.php.

How can I redirect these pages into the main site? Is there a plugin or a way to achieve it? | This is not wordpress related question but I will answer it without any special reason.
First of all... all pages from old website are indexed on google and those indexed pages can not be deindexed at the same moment when you change the website.

Register an additional image size for only some images in my media library

Thanks Marius | You don't say how you have set up the different adsense. I will assume that in your template there is a folder, called `'authors-ads'`, in it you have some php files, named after your **authors ids** , e.g.:

* `/authors-ads/author-12.php`
and so on.
after that in your `single.php` or whatever template you use to display posts
use
global $post;

Grab Wordpress Salt Data From URL
I'm looking to grab only the values of the Wordpress salt information from this URL with PHP:
<
I want to target the second set of values within single quotation marks. Is this do-able with regex? I'm having issues
$url = '
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post_data));
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$output= curl_exec($ch);
preg_match_all("/'(.*?)'/", $output, $matches, PREG_PATTERN_ORDER);
var_export($matches);
I'm working on a tool that will automatically grab the content from the url, strip out everything except for the values of the defined keys and return it in an array. It seems to mess up alot and doesn't bring back the proper values, is there any other way to target the defined values only from the second set of quotation marks?
Thanks | That returns PHP code. You can just eval it and then reference the various defines directly.
However, that is just a random number generator on the back end. There is no pattern to it. You can just generate your own random values instead of pulling them from WordPress.org and it will work just as well for whatever your purpose is. | stackexchange-wordpress | {

Setting Up "Split Site" Navigation in Wordpress
I'm currently attempting to set up a WordPress install for an organization which has two separate devisions. I'm having a very hard time wrapping my mind around how to create two navigation menus and reliably switch between them based on the currently viewed content.
I can't use multiple WordPress installs, as content will be shared in some cases and a single dashboard is preferred.
I tried using categories, but pages can't be assigned to a category. I tried using page parents, but posts can't be assigned a parent.
I'd like the solution to allow non-technical people to maintain both navigations easily.
How can I achieve this?
Related questions:
* Different menu navigation per category
* Get top level page parent title | You can use categories with pages, via `register_taxonomy_for_object_type`, but if you were to use a taxonomy for this, it may be better to register a custom taxonomy specifically for that purpose.
Another option is to add a meta box and provide simple means of selecting a menu, which would be saved and accessed via post meta data, otherwise known as Custom Fields. | stackexchange-wordpress | {

Update the value of a constant
I have a file containing all the constants used in the plugin. For example, I have a variable in one of my file `define('APPOINTMENTS_DEFAULT_ENABLE_PAYPAL', 1);`
I have a checkbox in admin area where user can enable or disable the paypal feature. This is the checkbox code: `<input type="checkbox" name="enable_paypal" size="40" value=""/>`
**Issue:** Can anybody please tell me how can I write code to modify the `define()` so that when checkbox is clicked then make the value to 1 and otherwise value should be 0? | You can't alter a constant once it is defined. That is how PHP works. Don't fight it.
The good news is that you should not be using a constant at all. Use options.
// get your value
// the second parameter is the default
$enable_paypal = get_option('enable_paypal',true);
// set your value based on, I assume, a form of some kind
update_option('enable_paypal',false);

Conditional On custom field plugin metabox
I've trying to run a conditional on the custom field I made with the Custom Fields plugin, I made a true and false check box.
I just need to check if the box is true or false really. I've tried something like this but the word hello appears even when the
<?php
$premium = get_field('premium');
if ( !isset($premium)) {
echo 'hello';
}
?>
Basically I've trying to change the page layout if this is ticked. I'm sure this is quite easy.
Thanks for any input | This can't work because `isset()` returns true if there is a value, `true`and `false` are values, ergo it won't work. Do it like this instead:
$premium = get_field('premium');
if ( ! $premium ) { // this is basically short for $premium == false
echo 'not premium';

How should I setup the "Users" area to hand over to a client?
We're about to hand over a Wordpress site to a client; this is the first one we've built from scratch.
Our "Users" area just consists boringly of the **admin** login with my work email like so:
!enter image description here.
What's the best way to set this up to hand over to the client? We want to retain the ability for us to login and support them and have full powers but not look like we still own it. As things stand, if we just add a couple of their members of staff to it now it'll still look like we're still the supreme user.
What do agencies normally do? This isn't a big project or client. They have a main person their end and a couple of junior users to help them. | 1. Create an admin level user for your client, preferably not one named "admin". If you track the number of attempted hacks on your site you will notice that most try to use the "admin" username.
2. Change the email for the admin use to reflect your client's email address
3. Or, preferably, delete the "admin" user and create another one with a less guessable name. | stackexchange-wordpress | {

How to use RSS reader plugin for displaying as posts?

Find and replace weird characters in the_content
So, I am using the following code to filter out certain letters.
$phrase = get_the_content();
$phrase = apply_filters('the_content', $phrase);
$replace = 'ï';
echo str_replace('ï', $replace, $phrase);
Unfortunately, it doesn't seem to handle special characters that well. Any ideas? | You could try this:
<?php
function replace_content($content)
{
$search = array('&', 'é', '—', '‘', '’', '“', '”');
$replace = array('&', 'é', '—', '‘', '’', '“', '”');
$content = str_replace($search, $replace, $content);
return $content;

Conditionally bypass plugin
I would like to defer the loading of an othervise active plugin for certain pages.
Since all plugins reside in the same folder, and WordPress only loads the activated ones, it must have an array of active plugin-handles at some point that it goes through. There's probably even a filter available to modify this array just before its being read (I'm hoping..).
So is it possible to conditionally bypass the loading of an otherwise active plugin, by removing it's handle from the list of active plugins, dynamically, without deactivating the plugin using deactivate_plugins()? | The list of active plugins is provided by `wp_get_active_and_valid_plugins()` during core load and comes from `active_plugins` option (multisite details aside).
While there is no explicit filter for it as any option it can be filtered via `'option_' . $option` hook (so `option_active_plugins`) and mu-plugin (which are being loaded earlier) should be able to do it.
Note that it is more common and better practice to control what plugin _does_ (such as thing it hooks) rather than if it loads completely. | stackexchange-wordpress | {

Why isn't my rewrite rule working when there is no second parameter?
Here is my rewrite rule code:
add_rewrite_rule('tides/([^/]+)/([^/]*)', 'index.php?page_id=4348&location=$matches[1]&month=$matches[2]', 'top');
add_rewrite_tag('%location%', '([^&]+)');
add_rewrite_tag('%month%', '([^&]*)');
This works great for the following URL:
/tides/mylocation/mymonth/
but 404's on the following:
/tides/mylocation/
I'm flushing the rewrite rules every time I change the code. I tried changing `*` to `+` but no help there.
Any ideas?
**Edit:**
Some answers were suggesting adding another rewrite rule so I added:
add_rewrite_rule('tides/([^/]+)/$', 'index.php?page_id=4348&location=$matches[1]', 'top');
before my other rule, but still no luck. | Your regular expression is requiring the last slash be present which it will not be by default. So the path `tides/mylocation/` is shortened to `tides/mylocation` and then tested. Instead, wrap the last part in an optional group using the `?` and update the match number.

User registration is currently not allowed
I'm running into issues on my localhost where when I navigate to my registration page I get the following error message _User registration is currently not allowed._
What I've tried so far:
1. I've checked my settings menu under `wp-admin/network/site-settings.php?id=1` and under _Users can register_ I have a `1` entered.
2. I've tried turning my plugins on and off.
3. I've checked `wp-admin/admin.php?page=bp-page-settings` and all necessary pages exist and are listed.
4. I've tried echoing `wp_register('','',false);` to see if that lends any clues and it just turns up blank.
This isn't the case on my other server (which I had thought was configured identically to my localhost). Registration is allowed and the echo above provides the link. No idea what's going on here and am working against a deadline (aren't we all, right?) so any ideas would be greatly appreciated. | No sooner did I post than I ran across this forum thread.

Orion theme (from theme forest)
I was given a theme called Orion available from themeforest. I had experienced troubles installing it via GUI (style.css was missing), therefore I did that operation manually by copying Update directory up the directory tree.
Now the theme appears somehow empty/broken. I was wondering whether this specific theme is meant to be standalone or just as an update to a prerequired theme (and which one, if this is the case).
Thank you!
Edit: I apologize as I wasn't clear enough. Is it normal that the theme .zip file which should be used to install the theme does not contain style.css? Why is the stylesheet only included in Update folder and what is (usually) the purpose of that subfolder? | Every WordPress theme, including child themes, is required to have a `style.css` file. The first few lines in `style.css` tell WordPress the name of the theme, the description, and some other meta information about the theme.

str_replace not responding in functions.php

preg_replace not removed "class"

return $output;
}
add_filter('post_thumbnail_html', 'the_post_thumbnail_remove_class');
It only works on the main page with highlighted images(thumbnail). | The hook `post_thumbnail_html` is just working for featured images aka post thumbnails, hence the name. I'm guessing that's what you're missing and where the "problem" originates.
But luckily there is another hook for manipulating image tags `get_image_tag`, there is actually one for just altering the class `get_image_tag_class` too. Take a look into those.
Another hook used in these scenarios is `wp_get_attachment_image_attributes`, but I only mention this one for completeness reasons. | stackexchange-wordpress | {

how to know if admin is in edit page or post
I use this after I checked if the user is admin
if ( isset($_GET['action']) && $_GET['action'] === 'edit' )
is there better way? | You can use `get_current_screen` to determine this.
$screen = get_current_screen();
if ( $screen->parent_base == 'edit' ) {
echo 'edit screen';
}
I don't know if I exactly would say this is always better, it depends on what's needed, but it's probably the way I'd do it. The big benefit with this method is that you get access to more information and ergo can do more and different distinctions. Just take a look at the documentation to understand what I mean.
It should be used in later hooks, Codex says:
> The function returns `null` if called from the `admin_init` hook. It should be OK to use in a later hook such as `current_screen`. | stackexchange-wordpress | {

http_response_timeout filter not working
I am writing a Wordpress plugin that makes calls to external sites. I want to raise the timeout for all `wp_remote_*` calls, so I added the following to the `__construct` function of my plugin:
add_filter("http_response_timeout", function($timeout) { return 30; });
But the calls still time out after 5 seconds. I also tried using a separate function as the second argument, same result. When I pass `array("timeout" => 30)` to the `wp_remote_*` functions directly, it works...
Any idea why the filter is not respected? | There is no filter named "http_response_timeout" in the WordPress core. Where are you finding this filter name from?
The timeout parameter as passed to a wp_remote call has a default of five seconds, and that default can be changed using the "http_request_timeout" filter, which is a different name than you used. Maybe you're just using the wrong word? | stackexchange-wordpress | {

how to make wordpress not to look for themes
For a particular project, I'm currently using only wp's admin and core functions/sugars, so no themes. Still, I'm forced to choose a theme.
I would like a couple of things:
1. move theme's functions.php (that currently contains only custom code by me) in /wp-contents, outside the themes and make WP still load it
2. force WP not to look for themes, so I can succefully delete the themes folder without getting an error in wp-admin
Is this possible? What's the best way (without hacking the core)?
Point 2 is less crucial, since I can always hide the admin's themes button. Point 1 is important.
For point 1, maybe I could load functions at the end of wp-config.php, or maybe (still in wp-config) I could hook at 'init' or 'setup_theme'. Or maybe something else.. I'd like to know the best practice here.
thank you | I can't see a reasons why you not just put your code from the `functions.php` into Plugins or Must Use Plugins, it isn't that hard to do and is, in my mind preferable, to connecting this task somehow to the `wp-config.php`.
Besides that, if you don't absolutely have to remove the backend/admin themes functionality itself, just remove, unset and/or make it inaccessible from the backend/admin area. Seems more practical to me, probably not knowing all the determining factors of course.
