I want override WP public function in plugin files. I want to place it on my theme functions.php file and don't want to directly edit plugin files because I want this function only applicable when using this theme only.
How can I override this public function?
class WP_Job_Manager_Post_Types {
public function application_details_email( $apply ) {
get_job_manager_template( 'job-application-email.php', array( 'apply' => $apply ) );
}
}
You could instead try the job_manager_locate_template filter:
add_filter( 'job_manager_locate_template',
function( $template, $template_name, $template_path )
{
if( 'job-application-email.php' === $template_name )
{
// modify $template;
}
return $template;
}
, 10, 3 );
to modify the template path.

I am learning about wordpress code and have read a lot of posts about add_action, but haven't found one yet that fits my situation. I want to make use of a hook that exists in another WP plugin. In rough outline, it looks like this:
// This part is not my code
class CDH {
function do_stuff() {
// important stuff
do_action( 'hook_i_want_to_use', $parameter );
// more stuff
}
global $cdh;
$cdh = new CDH();
}
// My first attempt code:
add_action( 'hook_i_want_to_use', 'my_function', 10, 1 );
function my_function( $parameter ) {
echo $parameter;
}
// My second attempt code:
class my_CDH extends CDH {
public function __construct() {
add_action( 'hook_i_want_to_use', array( $this, 'my_function' ), 10, 1 );
}
function my_function( $parameter ) {
echo $parameter;
}
}
In both attempts, my_function() is never called. How do I hook on to the do_action in the instance $cdh?
I want to perform unit tests on a Class, my goal is: I want to check if the plugin is activated or not by using the function: is_plugin_active
class WC_Custom_Variable_Products_Dependencies {
public function __construct() {
add_action( 'admin_init', [$this, 'check_environment']);
}
public function check_environment(){
return is_plugin_active(
'woocommerce-custom-variable-products/woocommerce-custom-variable-products.php'
);
}
}
CLass de test :
require_once 'class-wc-custom-variable-products-dependencies.php';
class WC_Custom_Variable_Products_DependenciesTest extends WP_UnitTestCase {
public function setUp() {
parent::setUp();
$this->class_instance = new WC_Custom_Variable_Products_Dependencies();
}
public function test_check_environment(){
$result = $this->class_instance->check_environment();
$this->assertTrue($result);
}
The assertion return always False .
My plugin is activated, and the function is_plugin_active returns True if I execute it from the browser:
add_action('admin_init', function(){
var_dump(is_plugin_active(
'woocommerce-custom-variable-products/woocommerce-custom-variable-products.php'
));
});
I think the admin_init hook is not executed in the test. is it true or not?
I found out why. here is the solution: you have to activate the plugin in the tests / bootstrap.php file:
$GLOBALS[ 'wp_tests_options' ] = array(
'active_plugins' => array(
'YOUR-PLUGIN/YOUR-PLUGIN.php'
)
)
On the Wordpress Codex page for 'register widget' there is basic example code given for registering a widget via your plugin:-
class MyNewWidget extends WP_Widget {
function __construct() {
// Instantiate the parent object
parent::__construct( false, 'My New Widget Title' );
}
function widget( $args, $instance ) {
// Widget output
}
function update( $new_instance, $old_instance ) {
// Save widget options
}
function form( $instance ) {
// Output admin widget options form
}
}
function myplugin_register_widgets() {
register_widget( 'MyNewWidget' );
}
add_action( 'widgets_init', 'myplugin_register_widgets' );
In this code, as you can see the three functions I mentioned are provided. I want to know if I can change their names or are they pre-created Wordpress functions?
You can name your members in MyNewWidget whatever you like, but the point of extending WP_Widget is that WP_Widget's methods are all available to MyNewWidget but you can override them by writing a method of the same name. This may help explain.
I'm trying to check if WooCommerce is active or not, I created a property with with a default value of false, then I created a method to check if WooCommerce is active using is_plugin_active() and admin_init hook, if active the value of the property must be updated to true: here is the code:
class MyClass{
public $woo_active = false;
public function __construct(){
add_action( 'admin_init', array( $this, 'check_if_woo_active' ) );
}
// check if WooCommerce is active
public function check_if_woo_active(){
if( is_plugin_active( 'woocommerce/woocommerce.php' ) ){
$this->woo_active = true;
}
}
// is_woo_active()
public function is_woo_active(){
return $this->woo_active;
}
}
$var = new MyClass();
var_dump( $var->is_woo_active() );
the issue is that var_dump returns false even if WooCommerce is active, BUT, if I use var_dump inside the function check_if_woo_active(), it returns true.
Why the property value is not updated? thanks
Updated:
The Second Solution as #helgatheviking sugested works fine, also this works very well and short
class MyClass{
// check if WooCommerce is active
public function is_woo_active(){
include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
if( is_plugin_active( 'woocommerce/woocommerce.php' ) ){
return true;
}else{
return false;
}
}
}
$var = new MyClass();
var_dump( $var->is_woo_active() );
If I had to guess, then $var = new MyClass(); is run before admin_init so the check_if_woo_active() isn't run.
Couple things you could do. First, I will usually launch my plugin on the woocommerce_loaded hook. That way I am 100% sure WooCommerce is running.
class MyClass{
protected static $instance = null;
/**
* Main MyClass Instance
*
* Ensures only one instance of MyClass is loaded or can be loaded.
*
* #static
* #see MyClass()
* #return MyClass - Main instance
* #since 0.1.0
*/
public static function instance() {
if ( ! isset( self::$instance ) && ! ( self::$instance instanceof MyClass ) ) {
self::$instance = new MyClass();
}
return self::$instance;
}
public function __construct(){
// Do what you want, WC is definitely active
}
}
/**
* Returns the main instance of class.
*
* #return MyClass
*/
function MyClass() {
return MyClass::instance();
}
// Launch the class if WooCommerce is loaded:
add_action( 'woocommerce_loaded', 'MyClass' );
You could also mimic what WooCommerce does with their premium plugins and check the option that stores the active plugins:
class MyClass{
private static $active_plugins;
public static function get_active_plugins() {
self::$active_plugins = (array) get_option( 'active_plugins', array() );
if ( is_multisite() ){
self::$active_plugins = array_merge( self::$active_plugins, get_site_option( 'active_sitewide_plugins', array() ) );
}
}
// check if WooCommerce is active
public static function check_if_woo_active() {
if ( ! self::$active_plugins ) self::get_active_plugins();
return in_array( 'woocommerce/woocommerce.php', self::$active_plugins ) || array_key_exists( 'woocommerce/woocommerce.php', self::$active_plugins );
}
}
var_dump( MyClass::check_if_woo_active() );
I'm trying to make a simple api call to a site that needs to render the data in a Wordpress Page/Widget.
I created a new page and put this code in the editor box on my dashboard:
<?php
$response = wp_remote_get( 'https://jsonplaceholder.typicode.com/posts/2' );
if( is_array($response) ) {
$header = $response['headers'];
$body = $response['body'];
}
print($response);
print($header);
print($body);
?>
Nothing is rendering on my Wordpress UI.
Yes, i'm on my local environment (using MAMP).
Solution:
Create a folder in your plugin directory and create a .php file that will be containing your api calls.
Your structure will look something like this:
class Api extends WP_Widget {
function __construct() {
$options = array(
'description' => '',
'name' => ''
);
parent::__construct('Api', 'Widget', $options);
}
public function form($instance) {
extract($instance);
// Put your HTML widget form here
}
public function widget($args, $instance) {
extract($args);
extract($instance);
$data = $this->get_api_call($args);
}
public function get_api_call($args) {
$api = wp_remote_get("http://www.example.com/json/");
$json_api = json_decode(stripslashes($api['body']));
return $json_api;
}
}
This is a basic outline instance, you'll have to customize everything according to what you exactly need from here.
