I'm trying to include a custom cookie in my Wordpress site, and I'm having some issues. I tracked down the last possible place for me to insert my cookie before headers got sent, which appears to be just before the last line in my wp-config.php
So I threw a require_once('path/to/cookie.php') at the end of my wp-config.php and was able to set the cookie. Whoopie. But each cookie's unique id needs to be stored in my database. So I invoked wp-load.php so I'd have the $wpdb global available, and then started attempting queries. 500 errors abound. What am I missing?
Here's the end of my wp-config.php
/* That's all, stop editing! Happy blogging. */
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . '/wp-content/plugins/myPlugin/cookie.php');
require_once(ABSPATH . 'wp-settings.php');
And here's cookie.php
$path = $_SERVER['DOCUMENT_ROOT'];
require_once $path . '/wp-load.php';
function rand_string( $length ) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$size = strlen( $chars );
for( $i = 0; $i < $length; $i++ ) {
$str .= $chars[ rand( 0, $size - 1 ) ];
}
return $str;
}
function check_id($id){
global $wpdb;
$results = $wpdb->get_results("SELECT id FROM visitors WHERE userid = '$id'");
if(mysqli_num_rows($results) > 0){
return false;
} else {
return true;
}
}
if(!isset($_COOKIE['visitor'])){
$key = false;
while($key == false){
if(check_id($userid = rand_string(32))){
$key = true;
}
}
setcookie("visitor", $userid, time() + ((86400 * 30)*12), "/", "site.com");
}
You can load WP files In cookie.php:
define( 'BLOCK_LOAD', true );
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-config.php' );
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-includes/wp-db.php' );
$wpdb = new wpdb( DB_USER, DB_PASSWORD, DB_NAME, DB_HOST);
Hope this works for you.

I am trying to add a suffix having certain values (such as min123) to all image URLs on my WordPress website getallnumber.com. The images are located in "/wp-content/uploads/year/month/". After adding the value the URL should be /wp-content/uploads/year/month/image.min123.png. I tried some pieces of codes including the sanitize code but there is no lock. Please help me out!
function sa_sanitize_special_chars ($filename) {
$f=remove_accents( $filename );
return 'min123-'.$f;
}
Add below code snippet in your active theme's functions.php file -
// wp media name suffix on upload
function modify_wp_handle_upload_prefilter( $file ) {
if( isset( $file['name'] ) ) {
$fileinfo = pathinfo( $file['name'] );
if( $fileinfo && isset( $fileinfo['filename'] ) && isset( $fileinfo['extension'] ) ) {
$suffix = 'min123'; // your suffix goes here
$name = $fileinfo['filename'] . '.' . $suffix . '.' . $fileinfo['extension'];
$file['name'] = $name;
}
}
return $file;
}
add_filter( 'wp_handle_upload_prefilter', 'modify_wp_handle_upload_prefilter', 99 );
I'm getting the error WP HTTP Error: cURL error 28: Operation timed out after 1001 milliseconds with 0 bytes received using the fetch_feed() method in my Wordpress Plugin.
This is for trying to fetch a larger RSS feed and I need to increase the Curl Timeout. Not sure why it is set to 1 second instead of 5 also?
The WP Documentation on this is not very detailed WP_Feed_Cache notably that SimplePie_Cache class documentation is not present.
Any help would be appreciated, not sure if I'm able to hook into SimplePie to increase the Curl Timeout. Also, I tried rewriting my own fetch_feed() method with no success below:
public function fetchFeed( $url ) {
if( ! class_exists('\SimplePie', false) ) {
require_once( ABSPATH . WPINC . '/class-simplepie.php' );
}
require_once( ABSPATH . WPINC . '/class-wp-feed-cache.php' );
require_once( ABSPATH . WPINC . '/class-wp-feed-cache-transient.php' );
require_once( ABSPATH . WPINC . '/class-wp-simplepie-file.php' );
require_once( ABSPATH . WPINC . '/class-wp-simplepie-sanitize-kses.php' );
$feed = new \SimplePie();
$feed->set_sanitize_class( 'WP_SimplePie_Sanitize_KSES' );
// We must manually overwrite $feed->sanitize because SimplePie's
// constructor sets it before we have a chance to set the sanitization class
$feed->sanitize = new \WP_SimplePie_Sanitize_KSES();
/* Customize sanitization */
$feed->sanitize->enable_cache = false;
$feed->sanitize->timeout = 60;
$feed->sanitize->useragent = "Custom Testing Feed Reader";
$feed->set_cache_class( 'WP_Feed_Cache' );
$feed->set_file_class( 'WP_SimplePie_File' );
$feed->set_feed_url( $url );
$feed->set_timeout( 30 );
/** This filter is documented in wp-includes/class-wp-feed-cache-transient.php */
$feed->set_cache_duration( apply_filters( 'wp_feed_cache_transient_lifetime', 60, $url ) ); //changing cache time to 60 seconds (instead of 12 hours)
/**
* Fires just before processing the SimplePie feed object.
*
* #since 3.0.0
*
* #param object $feed SimplePie feed object (passed by reference).
* #param mixed $url URL of feed to retrieve. If an array of URLs, the feeds are merged.
*/
do_action_ref_array( 'wp_feed_options', array( &$feed, $url ) );
$feed->init();
// $feed->set_output_encoding( get_option( 'blog_charset' ) );
$feed->set_output_encoding( "UTF-8" ); //set statically to UTF-8
if ( $feed->error() )
return new \WP_Error( 'simplepie-error', $feed->error() );
return $feed;
}
I was able to increase the Curl Timeout by using the following code:
//Set HTTP Request Timeout
add_filter('http_request_args', 'my_http_request_args', 100, 1);
function my_http_request_args( $r ) {
$r['timeout'] = 30;
return $r;
}
//Setting WP HTTP API Timeout
add_action('http_api_curl', 'my_http_api_curl', 100, 1);
function my_http_api_curl( $handle ) {
curl_setopt( $handle, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt( $handle, CURLOPT_TIMEOUT, 30 );
}
// Setting custom timeout for the HTTP request
add_filter('http_request_timeout', 'my_custom_http_request_timeout', 101 );
function my_custom_http_request_timeout( $timeLimit ) {
return 30;
}
I've searched seemingly every relevant question on this but I'm stuck, as none of them address the particular case of uploads through XML RPC.
I want to conditionally change the Wordpress file upload directory, only if the file is coming in through an XML RPC call and only if the call is coming in from a particular user.
My approach is based on a combination of this Answer, this Answer and the Codex.
Here's what I tried with no luck:
add_filter( 'xmlrpc_methods', 'call_intercept1' );
function call_intercept1( $methods ) {
$methods[ 'metaWeblog.newMediaObject' ] = 'custom_upload1';
return $methods;}
function custom_upload1( $args ) {
global $wpdb;
$username = $this->escape( $args[1] );
$password = $this->escape( $args[2] );
$data = $args[3];
$name = sanitize_file_name( $data['name'] );
$type = $data['type'];
$bits = $data['bits'];
if ( !$user = $this->login($username, $password) )
return $this->error;
if ( $username = "XXX" ) {
add_filter('upload_dir', 'custom_upload_dir1');
}
$upload = wp_upload_bits($name, null, $bits);
if ( ! empty($upload['error']) ) {
/* translators: 1: file name, 2: error message */
$errorString = sprintf( __( 'Could not write file %1$s (%2$s).' ), $name, $upload['error'] );
return new IXR_Error( 500, $errorString );
}
return $upload;
}
function custom_upload_dir1( $param ){
$custom_dir = '/the-desired-directory';
$param['path'] = $param['path'] . $custom_dir;
$param['url'] = $param['url'] . $custom_dir;
error_log("path={$param['path']}");
error_log("url={$param['url']}");
error_log("subdir={$param['subdir']}");
error_log("basedir={$param['basedir']}");
error_log("baseurl={$param['baseurl']}");
error_log("error={$param['error']}");
return $param;
}
The file is being uploaded correctly, but the conditional directory change isn't happening.
Does someone know why that would be?
I was able to get this worked out, essentially using Ulf B's Custom Upload Dir as a model and simplifying it from there.
For anyone else facing the same problem, here's what works:
// XMLRPC Conditional Upload Directory
add_action('xmlrpc_call', 'redirect_xmlrpc_call');
function redirect_xmlrpc_call($call){
if($call !== 'metaWeblog.newMediaObject'){return;}
global $wp_xmlrpc_server;
$username = $wp_xmlrpc_server->message->params[1];
$data = $wp_xmlrpc_server->message->params[3];
if($username !== "XXX"){return;}
else {custom_pre_upload($data);}}
function custom_pre_upload($data){
add_filter('upload_dir', 'custom_upload_dir');
return $data;}
function custom_post_upload($fileinfo){
remove_filter('upload_dir', 'custom_upload_dir');
return $fileinfo;}
function custom_upload_dir($path){
if(!empty($path['error'])) { return $path; } //error; do nothing.
$customdir = '/' . 'your-directory-name';
$path['subdir'] = $customdir;
$path['path'] .= $customdir;
$path['url'] .= $customdir;
return $path;}
I have the following code in my Wordpress. I need to add every uploaded image a counting number like, image_1, image_2, image_3 and so on..
The purpose of this is that every uploaded image attached to post, gets post ID name, and counting number in end to it.
It would be great if some one help me with this. Thanks!
<?php
add_filter('wp_handle_upload_prefilter', 'wpse_25894_handle_upload_prefilter');
add_filter('wp_handle_upload', 'wpse_25894_handle_upload');
function wpse_25894_handle_upload_prefilter( $file )
{
add_filter('upload_dir', 'wpse_25894_custom_upload_dir');
return $file;
}
function wpse_25894_handle_upload( $fileinfo )
{
remove_filter('upload_dir', 'wpse_25894_custom_upload_dir');
return $fileinfo;
}

if( !empty( $path['error'] ) || $use_default_dir )
return $path; //error or uploading not from a post/page/cpt

$customdir = '/' . $_REQUEST['post_id'];

// The filter runs when resizing an image to make a thumbnail or intermediate size.
add_filter( 'image_make_intermediate_size', 'wpse_123240_rename_intermediates' );
function wpse_123240_rename_intermediates( $image ) {
// Split the $image path into directory/extension/name
$info = pathinfo($image);
$dir = $info['dirname'] . '/';
$ext = '.' . $info['extension'];
$name = wp_basename( $image, "$ext" );
// Get image information
// Image edtor is used for this
$img = wp_get_image_editor( $image );
// Build our new image name
$postid = $_REQUEST['post_id'];
$random = rand(1,5);
$new_name = $dir . $postid . '_' . $random . $ext;
// Rename the intermediate size
$did_it = rename( $image, $new_name );
// Renaming successful, return new name
if( $did_it )
return $new_name;
return $image;
}
?>
Now this code generates images named postid_randomnumber.jpg
I just need to add 20 images at maximum, so if I can have numbers from 1-20, that is also working fine with my purposes.
-- UPDATE --
I canged the last part of code to this, it is not maybe the cleanest solution, but it works:
function wpse_123240_rename_intermediates( $image )
{
// Split the $image path into directory/extension/name
$info = pathinfo($image);
$dir = $info['dirname'] . '/';
$ext = '.' . $info['extension'];
$name = wp_basename( $image, "$ext" );
// Get image information
// Image edtor is used for this
$img = wp_get_image_editor( $image );
//$count = get_option( 'wpa59168_counter', 1 );
// Build our new image name
$postid = $_REQUEST['post_id'];
$increment = 1;
$new_name = $dir . $postid . '_1' . $ext;
while(is_file($new_name)) {
$increment++;
$new_name = $dir . $postid . '_' . $increment . $ext;
}
// Rename the intermediate size
$did_it = rename( $image, $new_name );
// Renaming successful, return new name
if( $did_it )
return $new_name;
return $image;
}
Is it possible for a file in the plugin directory to be used as a custom Page Template?
Also, how do you make a plugin create a page?
I'm developing a plugin for a client based on a theme, he wants this plugin to make sales pages while being able to use his theme on the homepage. This is a product that I'm making for him to market so it needs to be automated all through the plugin.
Is this possible?
EDIT
I have the activation/deactivation hooks in my plugins main file, and it's not working. Here's the code:
$filename = __FILE__;
register_activation_hook($filename, 'superActivation');
register_deactivation_hook($filename, 'superDeactivation');
global $myFile; global $fh; global $stringData; global $filename;
$myFile = "testFile.txt";
$stringData = "Testing\n";
$fh = fopen($myFile, 'w') or die("can't open file");
function superActivation() {
global $myFile; global $fh; global $stringData; global $filename;
fwrite($fh, $stringData);
fclose($fh);
}
function superDeactivation() {
$myFile = "testFile.txt";
unlink($myFile);
}
You can do this with the template_redirect hook. Here's my code to manually replace the template for a custom post type with one in the theme if there isn't one in the template folder. Put this in your plugin file and then put a folder underneath your plugin called themefiles with your default theme files.
//Template fallback
add_action("template_redirect", 'my_theme_redirect');
function my_theme_redirect() {
global $wp;
$plugindir = dirname( __FILE__ );
//A Specific Custom Post Type
if ($wp->query_vars["post_type"] == 'product') {
$templatefilename = 'single-product.php';
if (file_exists(TEMPLATEPATH . '/' . $templatefilename)) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect($return_template);
//A Custom Taxonomy Page
} elseif ($wp->query_vars["taxonomy"] == 'product_categories') {
$templatefilename = 'taxonomy-product_categories.php';
if (file_exists(TEMPLATEPATH . '/' . $templatefilename)) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect($return_template);
//A Simple Page
} elseif ($wp->query_vars["pagename"] == 'somepagename') {
$templatefilename = 'page-somepagename.php';
if (file_exists(TEMPLATEPATH . '/' . $templatefilename)) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect($return_template);
}
}
function do_theme_redirect($url) {
global $post, $wp_query;
if (have_posts()) {
include($url);
die();
} else {
$wp_query->is_404 = true;
}
}
You CAN add page templates from a plugin very easily by manipulating the page cache.
To customise, simply edit the following code block within the __construct method;
$this->templates = array(
'goodtobebad-template.php' => 'It\'s Good to Be Bad',
);
This is designed for a plugin (the template files are searched for in the root directory of the plugin). This can be changed if desired - check out my full tutorial http://www.wpexplorer.com/wordpress-page-templates-plugin/ for greater detail on this solution. These files are also in exactly the same format as if they were to be included directly in a theme.

I hope this helps you in what you want to do :)
the code david posted above almost works for me. but it seems to blanket over all posts and pages for me. This code below works great for adding a template to a single post type that is created by my main plugin file
function get_book_post_type_template($single_template) {
global $post;
if ($post->post_type == 'books') {
$single_template = dirname( __FILE__ ) . '/themefiles/single-books.php';
}
return $single_template;
}
add_filter( "single_template", "get_book_post_type_template" ) ;
but I'm having trouble getting it to work with a custom page templates that don't have a post_type or has a post_type = page for instance lets say the custom page is an auxiliary member login page to see my custom posts. in my case this file is called myaccount.php and i've included it in a subfolder within my plugin folder named themefiles.
//Add Page and Post Template Files to Current Theme
add_action("template_redirect", 'my_account_redirect');
function my_account_redirect() {
global $wp;
//Set myAccount Custom Page Template
if (isset($wp->query_vars['pagename'] ) == "myaccount") {
$templatefilename = 'myAccount.php';
if (file_exists(dirname( __FILE__ ) . '/themefiles/' . $templatefilename)) {
$return_template = dirname( __FILE__ ) . '/themefiles/' . $templatefilename;
}
do_account_redirect($return_template);
}
}
//Finishing setting templates
function do_account_redirect($url) {
global $post, $wp_query;
if (have_posts()) {
include($url);
die();
} else {
$wp_query->is_404 = true;
}
}
when i do the above code the myaccount template shows up on all pages except for home which i believe is because it is set to a blogroll instead of a static page
I cannot reply to user1912899, but their recommendation seems to be the most elegant solution. To use a custom template to override single-post.php, I've implemented the following code. This will work for any custom single-****.php file you add to your plugin. If it doesn't exist, it just falls back to what WordPress normally uses.
add_action('template_include', 'my_template_include');
function my_template_include($template) {
$file = dirname( __FILE__ ).'/theme/single-'.get_post_type().'.php';
if(file_exists($file)) {
$template = $file;
}
return $template;
}
