How do I insert an amazon search widget into posts or pages?
How do I insert an Amazon Search Widget into posts or pages? The source code is:
<SCRIPT charset="utf-8" type="text/javascript" src=" </SCRIPT> <NOSCRIPT><A rel="nofollow" HREF=" Widgets</A></NOSCRIPT>
* * *
**EDIT:**
The reason why the widget doesn't appear after embeded the above code into HTML is that the widget is blocked by **AdBlock**. | You're best bet is to put the amazon javascript script code into a widget, and then add the widget into a post/page using a shortcode. Give a look at this plugin.

Why does my content disapear when I make a page to match an archive name?
I made a custom post type called 'education'. I have added several pages to it. When it was first created I could go to < and see the posts, but I wanted to edit the layout. So I created a page called 'education' with the same permalink. Now it does not display any content.
Why does WordPress do this? How can I edit the layout if I can't create a page to attach a template? | The WordPress template hierarchy is your friend. <
This provides a very detailed flow for how WP determines which template to load.
If you are ever uncertain about which template is loading, this little function is handy. Paste in your theme's functions.php and it will display the template used at the bottom of the page.
add_action('wp_footer', 'wpse_show_template');
function wpse_show_template() {
global $template;
print_r($template);
}
That being said, creating a page with the same slug (education) as your post type archive will produce unexpected results, as you've seen.
The proper way to add your static content to the Education archive is via the archive-education.php template. | stackexchange-wordpress | {

How can I allow user to select minimum privilege smartly
We can easily asses a user's role using `current_user_can()`, but it doesn't support an array of user roles but a single role. So we have to check each of the role multiple times:
if( current_user_can('administrator') || current_user_can('editor') ) {
//do this
}
I'm making a WordPress Plugin, I need the administrator should choose the minimum privilege to administer the plugin. If the roles are hierarchical then they are like so (for single site):
* Administrator
* Editor
* Author
* Contributor
* Subscriber
If the admin choose author, then I have to do 3 OR checks as shown above ( _if x || y || z_ ).
Is there any smart way I can choose for this purpose so that I can let them choose the minimum privilege but I can handle it smartly too.
Thank you. | You are using the right WP function but unfortunately not passing the right parameter to make this work for you.
`current_user_can()` accepts capabilities as well as roles as parameters.
In the above you are using roles and not capabilities.
You can use capabilities to make it work.
For example, if you want the minimum privilege role is author your code would look like
if ( current_user_can( 'edit_published_posts' ) ) {
//do this
}
This will allow all the roles including author to have the privilege and would stop users with roles contributor and subscriber from the access.
You can read the details of roles and capabilities from the codex here. | stackexchange-wordpress | {

Menu Details Output in Javascript
I have to output page, parameters( Page Url, Page Name, and Page's featured image) in javascript loop, one by one
I think we can display it through NavMenuItems or NavMenu functions
Pages displayed will be those a user is allowed to see e by user hierarchy,
Any suggestions on how to proceed...?? | You can just use `wp_get_nav_menu_items( $menu, $args );` to get list of menu items created in appearance.
You can print result the way you want. Before printing just make sure the datas are not empty and so. I didn't add any validation. So use according to your need.
For example:
We'll try to print the data at `wp_head`
add_action('wp_head','menu_to_js');
function menu_to_js(){
$locations = get_nav_menu_locations();
$menu = wp_get_nav_menu_object( $locations[ $menu_name ] );//$menu_name should be your menu name
$menu_items = wp_get_nav_menu_items($menu->term_id);
$menu_items = json_encode($menu_items);
//So now we have json encoded $menu_items, put that in javascript
?>
<script>
var menu_itemss = "<?php echo $menu_items; ?>";
//now manipulate in js and use the way you want.

Cross reference custom post types
Just curious if can I autopopulate custom post fields (like checkboxes or select items) based on another custom posts setup?
My goal is to create a custom post types "employees" which can have assigned multiple service areas (stored as another custom post types), as group of checkboxes or drop downs fileds, as well will be able to assigned multiple office locations (stored as another custom post types) as well as group of checkboxes or drop downs fields to each employee. Main goal is to avoid redundancy and pull office locations and services from one centralized location as options fields for employees custom post type.
Or maybe there is a better solution to tackle that problem like using categories of employees custom posts for service areas and tags (for custom post types) as office locations?

Transfer WordPress post to RoR site: is the REST Api the only and/or best solution?

How can I use wordpress functionality outside of WP framework

I am new to Wordpress and stucked here. I already tried with include `wp-includes/post.php` file but i guess its still not working. Facing error regarding `undefined constant` and `function`. I don't know whether I am correct or not here. Is there any way to resolve this? | It's just simple, same reply from Error in WP_update_post but in your case there is small change.
Just use `wp-load.php` as include. No need to include `post.php`. Once the `wp-load.php` file is included, the entire wealth of WordPress functions is provided to you.
For pull the recent post, you need to use `wp_get_recent_posts()` wordpress function which is from WP framework.
So your PHP code will like:
<?php
// Include the wp-load'
include('YOUR_WP_PATH/wp-load.php');
// For example get the last 10 posts
// Returns posts as arrays instead of get_posts' objects
$recent_posts = wp_get_recent_posts(array(
'numberposts' => 10

Production Site: Moving from WordPress RC to Final Release Version

Editor / Add Media: Is it possible to only allow galleries?
I am writing a theme for a client where the employees sometimes have trouble using Wordpress correctly. I am using custom fields to let them add a gallery to a portfolio item (which is just a custom post type). Sometimes they just add images instead of a gallery, which is possible since the field in the portfolio is just a WYSIWYG Editor field with ACF. That is a problem because the layout is not working then.
The client now asked if it was possible to only allow them to add galleries. And not single images.
Is there a way to do that? Has anyone ever seen something like that? I know, it is ridiculous, but maybe there is a way... | I'm used to deal with ACF configurations and I think that the solution to your problem is quite simple, and is integrated in the ACF "gallery" field configuration options.
Check out this link, where you will find described all the options for a "gallery" field. As you will see, there's a parameter **"minimum selection"** which description is:
> The minimum number of images that are required for the field to validate. Defaults to 0
As simple as writing '2' in the configuration panel for this specific field, and ACF will check before saving if there are two or more images. If not, an alert message will appear.

Thanks | Trying to store markup in the database is generally a bad idea-- some reasons being:
1. Certain characters need to be escaped to be put in the database
2. Having markup in the database will negatively effect any searches you may need to run on the data, now or in the future.
3. Having markup in the database will complicate attempts to reuse the data in different contexts, now or in the future.
Just store the raw data in the database and format it on output. The basic code would look like:
$meta = get_post_meta($post->ID, 'post_subtitle', true);
if (!empty($meta)) {
$mstr = '<span class="some-class"'.$meta.'</span>';
}
You can automate that by creating a shortcode or by inserting it using the `the_content` filter, for example. | stackexchange-wordpress | {

I can't fetch query parameters ($_GET parameters) with get_query_var
I am developing pagination for a list of posts in my plugin. I've added a custom parameter in my `plugin_functions.php` file:
add_query_arg('pworkspage', 1);
As you can see it defaults to "1". Now, whenever I visit the custom admin page of my plugin with that parameter in the URL (`www.example.com/wp-admin/admin.php?page=mycustompage&pworkspage=2`) my script can't see the parameter at all.
I am retrieving the parameter like this:
$page_nr = get_query_var('pworkspage', 1);
The variable `$page_nr` is equal to `string(0) ""`.
I tried a different approach using the `query_vars` filter but I got the same results.
**Am I doing something wrong?** | Query vars are for use in the main `$wp_query` query object, your custom admin page has no main query, so no vars are parsed into a query object that can be accessed via `get_query_var`. I don't think there's anything WordPress-specific that can be used in this case, I would just access the value via `$_GET`. | stackexchange-wordpress | {

Create metaboxes based on custom post type

Where and how to define variables for URLs etc
I have one online version of a site, and one developer version which I am working and making changes on.
If I have a form with a url which the user will be redirected to:
<input type="hidden" name="cancelurl" value="
So when updating the live site, I have to change the url to the one that's valid for the live version.
So it would be more preferrable to use a variable or constant which is defined somewhere.
<input type="hidden" name="cancelurl" value="<?php $cancelurl ?>">
Then I can transfer the code without having to change the urls.
So my question is where and how do I define such variables or constants? | I believe you can just use `site_url()` \+ the path - so for instance:

Group child category IDs based on their parent category

* Parent category `1` has: `11,14`
* Parent category `2` has: `21`
* Parent category `3` has: `35,38,39`

array(
1 => array ( 11,14 ),
2 => array ( 21 ),
3 => array ( 35,38,39 )
) | The quick take would be something like this:
$categories = [ ];
$parent_categories = get_categories( [ 'parent' => 0 ] );
foreach ( $parent_categories as $parent_category ) {
$id = $parent_category->term_id;
$categories[ $id ] = wp_list_pluck( get_categories( [ 'parent' => $id ] ), 'term_id' );
}
The important bit is a `parent` argument, which limits retrieved to immediate children (parent of 0 is a top level).

How to read out the excerpt length (for if-condition)

echo str_word_count( strip_tags( get_the_excerpt() ) );

[
'date_query' => [

(edit) After some experimentation I found that when inserting a post of status "pending", it ignores the post_name parameter - so that ends up being blank in the database.

How to output the title of the blogs home page
I am using a static frontpage and a page for my blogposts. In my header.php I want to display the title of the selected page of my blogposts.
For example:
<?php
if( is_home() )
echo '<h1>' . get_the_title() . '</h1>';
?><nav>
...
</nav>
But of course `get_the_title()` returns the first element of the displayed posts and not of the page itself.
How can I display the title of the assigned home page? | You can make use the queried object to return the title of the page used as blogpage

Passing arguments to wp_list_comments callback function

$args = array( 'callback' => 'my_callback', 'avatar_size' => 48, 'type' => 'comment' );
wp_list_comments( $args );
The question is, how to pass arguments to that `my_callback` function? Already it gets three:
function my_callback( $comment, $args, $depth )
But I need to add my own 4th argument | Finally I figured it out. you may simply add your arguments to the `wp_list_comments` as associative `key` => `value` pairs like this:
$args = array( 'callback' => 'my_callback', 'avatar_size' => 48, 'type' => 'comment', 'arg1' => $arg1 );
wp_list_comments( $args );
and then in your `my_callback` you have:

Associating special meaning with user id 0
I'm writing a plugin that creates a custom table holding data which is linked to a user account with a `user_id` field. Now if that users account would be deleted for any reason I would like to set that `user_id` field in my custom table to `0` to keep the stored data in an anonymized fashion.
Since the first user `ID` is `1` and counted upwards from there I would assume this is save. Is there any reason why this might have unwanted side effects?

Images showing in editor but not in post
Images are showing up in the editor, but not in the post. What's weird is that on initial page load, the images flash into existence and then disappear with a broken image icon. Here is an example post:
<
This site is brand new on Wordpress.com. Everything was imported from an pre-existing self-hosted WordPress site (I used the built-in export tool to generate an XML file). It looks like the images did make it over in the import.
On this post, in the browsers web inspector, it shows the source of one of the misfiring images as...
<
...which loads fine on its own, but not in the post itself. So confusing! | It shows on your new site that it reflects the old domain ` if you are not planning to use your domain ` you need to re import your xml file to and do a find and replace of the string from ` to ` before importing them.
If you will be using your domain ` in the wordpress.com site instead of the free tier appending the `wordpress.com` in the URL, I think that should automatically fix your problem | stackexchange-wordpress | {

query_posts by category_name and custom taxonomy

wp enqueue, how to prevent duplication when same script is registered with different handles
I read that wp enqueue prevents duplicate script to be loaded. But, what happens when same script ( say bootstrap.js) is loaded by 2 different plugins with 2 different handles using wp enqueue ? | JS/CSS Duplication by itself is not bad. It makes the HTML a little bigger nut the browser should in most cases cache the first request and not serve the second one (most cases === unless it is a very badly configured server)
The real problem with duplication is trying to load two different versions of the same file (say two different versions of jQuery), and this is what the API helps to solve by providing a handle to the version which already exists as part of core.
The best thing in your case is to probably think again why do you even need bootstrap in a plugin, why the admin CSS and JS is not enough for you. | stackexchange-wordpress | {

TOO MANY REDIRECTS ERROR when redirecting buddypress register page to WordPress sign up
I have a problem with using Wordpress registration page instead of BuddyPress page, that when I use the snippets given in github and add them to a file named (bp-custom.php) or functions.php file I get an error telling me that there are too many redirects.
I was adviced to remove the second snippet of the link and this removed the error from the page but yet I get an empty buddypress registration page!
Any ideas on how to solve this problem? | Had the same problem Found this solution in my intense google search:

What does wp-embed.min.js do in WordPress 4.4?
**Question**
1. What does the `wp-embed.min.js` file do? I noticed it is added to the end of my blog page footer.
2. How can I get rid of it?
**Effort**
After some googling and I found Embeds on the Codex. Why does WordPress think I want to add videos, etc. to my page by default?
**Environment**
WordPress 4.4 | ## What is it?
It is responsible for converting links into embed frames.
For example you can paste a Youtube video link into the editor content section and the Youtube embed will be generated for you when your page is viewed.
More information on WordPress Documentation
## How to get rid of it?
I could finally get rid of that using this:
function my_deregister_scripts(){
wp_deregister_script( 'wp-embed' );
}

Not sure if I should create multiple custom post type
I am working on a projects that has different tutorials, such as js, html, css and etc.
I was initially thinking to create one custom post type for each tutorials, but after some research, I think maybe it is better to create one custom post type called Tutorial, and have different categories under it, like js, html, css and etc.
I am not sure which approach is better. I am more concern about the performance and SEO. Can someone share the thoughts, pros and cons with each approach.
Thank you. | You shouldn't create multi custom post type, Think your project scope clearly.For Tutorials like html,css, js or other tutorials, you should create only tutorials custom post type. So that
yourdomain.com/tutorials
yourdomain.com/tutorials/html/
yourdomain.com/tutorials/js
It's more readable and good for SEO. Analyze the project flow clearly and then you could configure well for that. Good luck in codes :) | stackexchange-wordpress | {

My simple custom shortcode is not longer working (possibly due to upgrade to WordPress 4.4 ?)
I have a simple function in functions.php that creates a custom shortcode:
function my_line_break() {
return "<br>";
}
add_shortcode( 'new line', 'my_line_break' );

Anyone can help with this? I looked at < but I'm not sure it relates?
P.S. I know this wouldn't be the right way to handle line breaks, but I did it as a way to make life simpler for my customer (so as a little side question, if there is a valid and simple to use alternative, could you please let me know it so I can also bypass this problem completely?). | Converting the comment to an answer,

Retrieve value of a category's custom field
Using the 'Advanced custom fields' plugin I have added a field to every post category that is called 'color' and it works just fine.
Now inside the loop I need to retrieve the value of the 'color' field, I have followed many other tutorials, but I could not achieve the result needed.
Here is the exaple of how the loop is set up:
while ( $projects->have_posts() ) {
$projects->the_post();
$category_classes = array();
$categories = get_the_terms( get_the_ID(), 'project_category' );
if ( $categories ) {
foreach ( $categories as $category ) {
$categories_included[] = $category->term_id;
}
}
Now in perfect scenario, I need to get the 'color' of a category inside the foreach loop.
Any help or guidance is much appreciated. | < prety much covers what you're after I believe.
So in your example
while ( $projects->have_posts() ) {
$projects->the_post();
$category_classes = array();
$categories = get_the_terms( get_the_ID(), 'project_category' );
if ( $categories ) {
foreach ( $categories as $category ) {
$categories_included[] = $category->term_id;
$color = get_field('color', 'project_category_'.$category->term_id);
}
}
You can also pass a term to get_field and the_field, so you could also use the following depending on your version of ACF as I believe much older versions don't support passing terms

POSTS list in WordPress by views
I need a code that causes: `<?php while ( have_posts() ) : the_post(); ?>` List according to the amount of VIEW, is like to list popular posts only that it will enter the table **mh_postmeta** , and list according to who has the most **view**.
![inserir a descrição da imagem aqui](
The staff uses the 'orderby' => 'comment_count', to list according to the comments, but need it to search for another table, **BUT** , this can only happen to certain category .. Let's say you have 40 **CAT** it should only list by **VIEW** instead of **DATE** in **CAT 3** | Seems like you already have the custom field for views set up since that's a phpMyAdmin screenshot. If so, you can use `order_by="post_views_count"` in most `wp_query` based calls. For instance:
$args = array(
'post_type' => 'your_post_type',
'orderby' => 'meta_value_num',
'meta_key' => 'post_views_count',
);
$query = new WP_Query( $args );
//...and on with the loop
<?php while ( have_posts() ) : the_post(); ?>...
Limiting this behavior to category 3 is pretty easy but how go about it depends on the context and your template setup.

How do I Turn This Into An if statement?
PHP noob here. I've got this query I've written to get the information of all child pages of the page you're currently on:

<?php
}

But I don't know the correct syntax to turn this into an if statement, followed by an else statement so I can say "There's no content here. Check back later." Or something like that.

Prevent WordPress from adding image' title automatically
I wrote a plugin that set default title for all non-set (empty) titles and leaves the titles set manually (non-empty).
The problem is when I upload new photos (to gallery), WordPress by default set the title to file's name. How Can I disable it and **force WordPress to use empty string as default image title**? | You can try the following to clear the image attachment's title when it's _inserted_ but not _updated_ :
/**
* Empty the image attachment's title only when inserted not updated

add_filter( 'wp_insert_attachment_data', function( $data, $postarr )
{
if(
empty( $postarr['ID'] )

&& wp_match_mime_types( 'image', $postarr['post_mime_type'] )
)
$data['post_title'] = '';
return $data;
}, 10, 2 );
Here we use the `wp_insert_attachment_data` filter to override the attachment's title if the attachment's `ID` is empty and the mime type is an _image_ type according to `wp_match_mime_types()`. A simple `'image' === substr( $postarr['post_mime_type'], 0, 5 )` check might work as well. You could even target a given mime type, like `image/jpeg`. | stackexchange-wordpress | {

Correct way to hide pseudo pages from being shown?
