I'm sorry, I'm noob in PHP and I feel like asking a very basic question. Anyway a can't find the answer. I'm trying to ask Facebook if a person likes a facebook page. I've seen in the SDK that it's done with this code:
$request = new FacebookRequest(
$session,
'GET',
'/me/likes/<page_id'
);
But when I try to do it, I get the following error:
PHP Fatal error: Class 'Facebook\HttpClients\FacebookStreamHttpClient' not found in (...)/Facebook/FacebookRequest.php on line 161
Sounds like Facebook/HttpClients/FacebookStreamHttpClient is not loaded. Anyway, I think it should be loaded by acebook/FacebookRequest, isn't it?
I already loaded the following files:
require_once( 'Facebook/FacebookSession.php' );
require_once( 'Facebook/FacebookRedirectLoginHelper.php' );
require_once( 'Facebook/FacebookRequest.php' );
require_once( 'Facebook/FacebookResponse.php' );
require_once( 'Facebook/FacebookSDKException.php' );
require_once( 'Facebook/FacebookRequestException.php' );
require_once( 'Facebook/FacebookAuthorizationException.php' );
require_once( 'Facebook/GraphObject.php' );
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
You need to make sure you include those classes in your code:
require_once( 'Facebook/HttpClients/FacebookHttpable.php' );
require_once( 'Facebook/HttpClients/FacebookCurl.php' );
require_once( 'Facebook/HttpClients/FacebookCurlHttpClient.php' );
use Facebook\HttpClients\FacebookHttpable;
use Facebook\HttpClients\FacebookCurl;
use Facebook\HttpClients\FacebookCurlHttpClient;

I've used wp_handle_upload from the front end and it works fine.
Now I want to receive base64 string (jpg) from API POST store in metabox then turn it in to jpg(until here it works fine). Then I need to upload it in the media library and attach it to a post.
when I pass the file with file_get_contents or fopen it does not work. Any ideas?
function base64ToImage($base64){
$img = base64_decode($base64);
require_once( ABSPATH . 'wp-admin/includes/image.php' );
require_once( ABSPATH . 'wp-admin/includes/file.php' );
require_once( ABSPATH . 'wp-admin/includes/media.php' );
// wp_handle_upload( $_POST['img'], 0 );
$fp = fopen(get_template_directory()."/xxxxxxxxxxxxxxxxxxxxxxxxx.jpg", "w+");
// write the data in image file
fwrite($fp, base64_decode($base64));
// close an open file pointer
fclose($fp);
wp_handle_upload( file_get_contents("../" ."/xxxxxxxxxxxxxxxxxxxxxxxxx.jpg"), 0 );
return 0;
}
So to my past self and to anyone that might find this useful.
I used the wp_upload_bits function instead, subsequently I used
-wp_insert_attachment
-wp_generate_attachment_metadata
-wp_update_attachment_metadata
-set_post_thumbnail in order to associate the image with a specific parent post.
I am trying to force plugin updates with WordPress, but it doesn't seem to be working. I need to force these updates within a custom plugin itself.
I added the following filter into my plugin:
add_filter( 'auto_update_plugin', '__return_true' );
I made sure that nothing in the wp_config file disallows auto-updates. Even though I didn't need to, to be safe I also set:
define( 'FS_METHOD', 'direct' );
and define( 'WP_AUTO_UPDATE_CORE', true );
I then installed the Advanced Cron Manager plugin to trigger the wp_update_plugins event, but this did not update any plugins.
I decided to simply call the wp_maybe_auto_update() function within my plugin on init... and it worked and updated my plugin - but also disabled it!
I am wondering if anyone knows why running the wp_update_plugins cron event wouldn't be updating any plugins? There must be a really simple solution here that I'm missing! Your help would be much appreciated!
You could use the following function to update a plugin programatically:
function upgrade_plugin( $plugin_slug ) {
include_once ABSPATH . 'wp-admin/includes/class-wp-upgrader-skin.php';
include_once ABSPATH . 'wp-admin/includes/class-wp-upgrader.php';
wp_cache_flush();
$upgrader = new Plugin_Upgrader();
$upgraded = $upgrader->upgrade( $plugin_slug );
return $upgraded;
}
& you could use that in conjunction with get_plugins
// Check if get_plugins() function exists. This is required on the front end of the
// site, since it is in a file that is normally only loaded in the admin.
if ( ! function_exists( 'get_plugins' ) ) {
require_once ABSPATH . 'wp-admin/includes/plugin.php';
}
$all_plugins = get_plugins();
and then loop over it to update the plugins
foreach ( $all_plugins as $key => $value ) {
upgrade_plugin( $key );
}
I found this article useful when putting together this answer: https://wpreset.com/programmatically-automatically-download-install-activate-wordpress-plugins/
From the answer above I got this to work, you just need to remove the extra / from include_once ABSPATH . '/wp-admin/includes/class-wp-upgrader-skin.php';
to make it: include_once ABSPATH . 'wp-admin/includes/class-wp-upgrader-skin.php';
When I am relying on a cron event (Testing with WP Crontrol plugin) to take care of plugin update, following code seems to be working with given required files:
include_once ABSPATH . 'wp-admin/includes/file.php';
include_once ABSPATH . 'wp-admin/includes/class-wp-upgrader.php';
include_once ABSPATH . 'wp-admin/includes/misc.php';
$upgrader = new Plugin_Upgrader();
$result = $upgrader->upgrade($plugin_slug);
if (is_wp_error($result) || !$result) {
// Check if error, else updated successfully
}
I want to compare the current version of my custom plug-in with update version of plug-in.
I get updated version of plug-in in response from server.
How can I get current version of my plug-in?
You can use get_file_data() function which is available on frontend and backend. For example:
get_file_data('/some/real/path/to/your/plugin', array('Version'), 'plugin');
if you use get_plugin_data() on the frontend it will throw an error Call to undefined function get_plugin_data(). Here is the correct way to get plugin header data.
if ( is_admin() ) {
if( ! function_exists( 'get_plugin_data' ) ) {
require_once( ABSPATH . 'wp-admin/includes/plugin.php' );
}
$plugin_data = get_plugin_data( __FILE__ );
echo "<pre>";
print_r( $plugin_data );
echo "</pre>";
}
You could save you version in the options table for easy retrieval. But you can also use get_plugin_data for more details about a given plugin.
<?php
$data = get_plugin_data( "akismet/akismet.php", false, false );
?>
Please note that get_plugin_data is only available in the WordPress admin, it's not a front-end available function.
For users who land on this question to find out the current version of WordPress itself use this function.
// it will show only numeric value i.e 5.8.2
echo get_bloginfo( 'version' );
I'm having error when i call the_meta() from single.php, im using wordpress 3.4.1, and WordPress Alchemy Metabox Class 1.4.17, my functions.php
include_once ( get_template_directory() .'/metaboxes/setup.php');
include_once( get_template_directory() .'/metaboxes/custom-spec.php');
my setup.php
include_once WP_CONTENT_DIR . '/wpalchemy/MetaBox.php';
include_once WP_CONTENT_DIR . '/wpalchemy/MediaAccess.php';
// include css to help style our custom meta boxes
add_action( 'init', 'my_metabox_styles' );
function my_metabox_styles()
{
if ( is_admin() )
{
wp_enqueue_style( 'wpalchemy-metabox', get_stylesheet_directory_uri() . '/metaboxes/meta.css' );
}
}
$wpalchemy_media_access = new WPAlchemy_MediaAccess();
custom-spec.php
<?php
$custom_mb = new WPAlchemy_MetaBox(array
(
'id' => '_custom_meta',
'title' => 'My Custom Meta',
'template' => get_stylesheet_directory() . '/metaboxes/custom-meta.php',
));
and single.php
<?php //inside loop.......... ?>
<?php global $custom_mb ?>
<?php echo $custom_mb->the_meta();?>
ERROR is :Fatal error: Call to a member function the_meta() on a non-object in C:\wamp\www\wp\wp-content\themes\twentyeleven\single.php on line 19
pleas help me to find the cause of error
The main issue here is that the global $custom_mb is most probably nothing. So asking it to have a value is what is causing the error.
It does look like you have the correct code as per example here: http://www.farinspace.com/wpalchemy-metabox/
Use print_r($custom_mb); after the global to see what it holds. If it's nothing you know somethings wrong.
Also, the code you say is inside the loop should be just outside of it.
(Update) FIX: Add global $custom_mb; to the top of the new php page.
I want to keep the admin in english but the theme in another language. By adding language files to the theme directory nothing happens, the option to switch language wont come up. Is this possible without adding languages to wp-content?
I found a solution using the locale filter and load theme textdomain
The solution looks like this:
define('LOCALE', 'en');
add_action( 'after_theme_setup', 'site_setup' );
function site_setup() {
//Make the theme available for translation
load_theme_textdomain( 'mytheme', get_template_directory() . '/languages' );
$locale = get_locale(); //Will get what you defined earlier
$locale_file = get_template_directory() . "/languages/$locale.php";
if ( is_readable( $locale_file ) ) require_once( $locale_file );
}
