I'm trying to add a custom default avatar to WordPress in functions.php, but the image is not displaying in Settings/Discussion or elsewhere on the site. The code works because a new radio field is added with the custom field name, but the image won't display. Is the avatar not displaying because I'm using Localhost?
I don't have enough reps to comment on similar questions.
here's the code:
add_filter( 'avatar_defaults' , 'wps_new_avatar' );
function wps_new_avatar( $avatar_defaults ){
$new_avatar = get_stylesheet_directory_uri() . '/images/default-avatar.png';
$avatar_defaults[$new_avatar] = "Default Avatar";
return $avatar_defaults;
}
I've tried other examples and the 'Add-New-Default-Avatar' plugin with the same result.
I was facing the same issue and came up with this completely hackish solution... It works though :)
add_filter( 'get_avatar', 'so_14088040_localhost_avatar', 10, 5 );
function so_14088040_localhost_avatar( $avatar, $id_or_email, $size, $default, $alt )
{
$whitelist = array( 'localhost', '127.0.0.1' );
if( !in_array( $_SERVER['SERVER_ADDR'] , $whitelist ) )
return $avatar;
$doc = new DOMDocument;
$doc->loadHTML( $avatar );
$imgs = $doc->getElementsByTagName('img');
if ( $imgs->length > 0 )
{
$url = urldecode( $imgs->item(0)->getAttribute('src') );
$url2 = explode( 'd=', $url );
$url3 = explode( '&', $url2[1] );
$avatar= "<img src='{$url3[0]}' alt='' class='avatar avatar-64 photo' height='64' width='64' />";
}
return $avatar;
}
Result:
Of course, this filter is meant for development only.

I'm trying to get WordPress theme name using API. I have tried this code but I want the same result using custom url:
function theme_list_function(){
// Get a list of themes
$list = wp_get_themes();
// Return the value
var_dump($list);
}
This code will return current WordPress theme list. I want theme list form a URL like xyz.com
I have achieved this using this code:
$target_site = ""; // put your wordpress url here
$src = file_get_contents( $target_site );
preg_match("/\<link rel='stylesheet'.*href='(.*?style\.css.*?)'.*\>/i", $src, $matches );
if( $matches ) {
$style_href = trim( $matches[1] );
$style_src = file_get_contents( $style_href );
preg_match( "/\Theme Name:(.*?)\n/i", $style_src, $theme_name );
$theme_name = str_replace(' ', '', $theme_name[1]);
var_dump( $theme_name );
}
When sharing a post to Discord, the preview Discord generates shows the author name and URL. We removed all information about the author but it didn't stop the author tag from showing.
That’s done via oEmbed. Add below code in your functions.php file
add_filter( 'oembed_response_data', 'disable_embeds_filter_oembed_response_data_' );
function disable_embeds_filter_oembed_response_data_( $data ) {
unset($data['author_url']);
unset($data['author_name']);
return $data;
}
**disorc may have stored the response in cache so create new post or page and test that **
#hrak has the right idea but his answer lacks context for those of us not used to dealing with PHP.
What I ended up doing was check if there was already a filter for 'oembed_response_data' in /wp-includes/default-filters.php. Mine looked like this:
add_filter( 'oembed_response_data', 'get_oembed_response_data_rich', 10, 4 );
Add the previous line to the specified file if, for whatever reason, it isn't there already.
Afterward, I checked in wp-includes/embed.php for the get_oembed_response_data_rich function, which looked like this:
function get_oembed_response_data_rich( $data, $post, $width, $height ) {
$data['width'] = absint( $width );
$data['height'] = absint( $height );
$data['type'] = 'rich';
$data['html'] = get_post_embed_html( $width, $height, $post );
// Add post thumbnail to response if available.
$thumbnail_id = false;
if ( has_post_thumbnail( $post->ID ) ) {
$thumbnail_id = get_post_thumbnail_id( $post->ID );
}
if ( 'attachment' === get_post_type( $post ) ) {
if ( wp_attachment_is_image( $post ) ) {
$thumbnail_id = $post->ID;
} elseif ( wp_attachment_is( 'video', $post ) ) {
$thumbnail_id = get_post_thumbnail_id( $post );
$data['type'] = 'video';
}
}
if ( $thumbnail_id ) {
list( $thumbnail_url, $thumbnail_width, $thumbnail_height ) = wp_get_attachment_image_src( $thumbnail_id, array( $width, 99999 ) );
$data['thumbnail_url'] = $thumbnail_url;
$data['thumbnail_width'] = $thumbnail_width;
$data['thumbnail_height'] = $thumbnail_height;
}
return $data;
}
I just added the two lines of code that #hrak introduced in his answer to remove the author tag (name and URL) from $data before it was returned:
function get_oembed_response_data_rich( $data, $post, $width, $height ) {
(...)
if ( $thumbnail_id ) {
list( $thumbnail_url, $thumbnail_width, $thumbnail_height ) = wp_get_attachment_image_src( $thumbnail_id, array( $width, 99999 ) );
$data['thumbnail_url'] = $thumbnail_url;
$data['thumbnail_width'] = $thumbnail_width;
$data['thumbnail_height'] = $thumbnail_height;
}
unset($data['author_url']);
unset($data['author_name']);
return $data;
}
As before, add the get_oembed_response_data_rich function if it does not already exist. After about 5-10 minutes, Discord link embeds stopped showing the author tag.

I've done this by emptying the posted_by function like this article shows, in the "Use Code to Remove the Author Name" section
https://wpdatatables.com/how-to-hide-the-author-in-wordpress/
basically find the posted_by function and empty it
function twentynineteen_posted_by() {
}
endif;
I am using Wordpress 3.5, I have a custom post (sp_product) with a metabox and some input field. One of those input (sp_title).
I want to Search by the custom post title name by typing in my input (sp_title) field and when i press add button (that also in my custom meta box), It will find that post by that Title name and bring some post meta data into this Meta box and show into other field.
Here in this picture (Example)
Search
Click Button
Get some value by AJAX from a custom post.
Please give me a example code (just simple)
I will search a simple custom post Title,
Click a button
Get the Title of that post (that i search or match) with any other post meta value, By AJAX (jQuery-AJAX).
Please Help me.
I was able to find the lead because one of my plugins uses something similar to Re-attach images.
So, the relevant Javascript function is findPosts.open('action','find_posts').
It doesn't seem well documented, and I could only found two articles about it:
Find Posts Dialog Box
Using Built-in Post Finder in Plugins
Tried to implement both code samples, the modal window opens but dumps a -1 error. And that's because the Ajax call is not passing the check_ajax_referer in the function wp_ajax_find_posts.
So, the following works and it's based on the second article. But it has a security breach that has to be tackled, which is wp_nonce_field --> check_ajax_referer. It is indicated in the code comments.
To open the Post Selector, double click the text field.
The jQuery Select needs to be worked out.

Here I want to have upon activation of my wordpress plugins activation
Before Activation
Activate | Edit | Delete
After Activation
Settings | Edit | Delete
How can this be done in code to add this Menu?
I personally use the following snippet of code to add new action links. I found this elsewhere and modified as needed.
function my_plugin_admin_action_links($links, $file) {
static $my_plugin;
if (!$my_plugin) {
$my_plugin = plugin_basename(__FILE__);
}
if ($file == $my_plugin) {
$settings_link = 'Settings';
array_unshift($links, $settings_link);
}
return $links;
}
add_filter('plugin_action_links', 'my_plugin_admin_action_links', 10, 2);
There's a filter for plugin_action_links that you can set specifically for your plugin to add action links for your plugin on the Plugins page
Check out these blogs for more detail:
http://adambrown.info/p/wp_hooks/hook/%7B$prefix%7Dplugin_action_links
http://www.wpmods.com/adding-plugin-action-links/
There are two types of links in plugin list.Taken from
http://atiblog.com/wordpress-plugin-development/
Use the following code in your Class.
For Type 1:
add_action( 'plugin_action_links_' . plugin_basename( FILE ),array($this,'plugin_links') );
function plugin_links( $links ) {
$links = array_merge( array('' . __( 'Settings', 'textdomain' ) . ''), $links );
return $links;
}
For Type 2 : use filter.
add_filter( 'plugin_row_meta', array($this,'plugin_row_meta_links'), 10, 2 );
function plugin_row_meta_links( $links, $file ) {
$base = plugin_basename( FILE );
if ($file == $base ) {
$new_links = array(
'donate' => 'Donate',
'doc' => 'Documentation'
);
$links = array_merge( $links, $new_links ); }
return $links;
}
What I'm trying to do is change the link to the main attachment page in Wordpress. Basically, I'm trying to change the word attachment to media.
I'm trying to change:
example.com/parent-category/child-category/post-slug/attachment/attachment-name/
to:
example.com/parent-category/child-category/post-slug/media/attachment-name/
Thanks in advance for any help on this.
I know this is an old question, but I just stumbled on it and thought it was worth a shot;
function __filter_rewrite_rules( $rules )
{
$_rules = array();
foreach ( $rules as $rule => $rewrite )
$_rules[ str_replace( 'attachment/', 'media/', $rule ) ] = $rewrite;
return $_rules;
}
add_filter( 'rewrite_rules_array', '__filter_rewrite_rules' );
function __filter_attachment_link( $link )
{
return preg_replace( '#attachment/(.+)$#', 'media/$1', $link );
}
add_filter( 'attachment_link', '__filter_attachment_link' );
