1) clear cache  :  php bin/magento cache:flush

2) reindex :  php bin/magento indexer:reindex

3) cmd to deploy static data  :  php bin/magento setup:static-content:deploy  en_US en_AU

4) show which mode is active developer or production

         php bin/magento deploy:mode:show

        set developer mode :  php bin/magento deploy:mode:set developer
        set production mode :php bin/magento deploy:mode:set production

5) check module status
     php bin/magento module:status

6) Enable module
       php bin/magento module:enable Your_modulename --clear-static-content
       eg. php bin/magento module:enable Rain_Affiliate --clear-static-content

7) Dissable module
      php bin/magento module:disable Magento_Weee

8 ) After install module  you have to run this 2  command
        php bin/magento setup:upgrade
        php bin/magento setup:di:compile

please follow the step as i show below

Is your WooCommerce Sample e is adding full price of your product rathan than custome sample price than this is the solution for it


just copy and paste this code into the respective file

/wp-content/plugins/woocommerce-sample/woocommerce-sample.php

1)  add this code in init() function
//custome RI code start
add_action( 'woocommerce_before_calculate_totals','cp_add_custom_price', 10, 2);
function cp_add_custom_price( $cart_obj ) {
// This is necessary for WC 3.0+
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;

foreach ( $cart_obj->get_cart() as $key => $value ) {
if($value['sample']){
$product_id = $value['product_id'];
$sample_price_mode = get_post_meta($product_id, 'sample_price_mode', true) ? get_post_meta($product_id, 'sample_price_mode', true) : 'default';
$sample_price = get_post_meta($product_id, 'sample_price', true) ? get_post_meta($product_id, 'sample_price', true) : 0;
if ($sample_price_mode === 'custom'){
$price = $sample_price;
}else if ($sample_price_mode === 'free'){
$price = 0;
}else{
$price = $value['data']->price;
}
$value['data']->set_price( $price );


}

}
}
//custome RI code start

2) Add this code inside the foreach loop of mini-cart file
    note: $product_id variable is before this code ,
     $_product   variable is after this code



/wp-content/plugins/woocommerce/templates/cart/mini-cart.php

//custome RI code start
$product_id   = apply_filters( 'woocommerce_cart_item_product_id', $cart_item['product_id'], $cart_item, $cart_item_key );

if($cart_item['sample']){
$sample_price_mode = get_post_meta($product_id, 'sample_price_mode', true) ? get_post_meta($product_id, 'sample_price_mode', true) : 'default';
$sample_price = get_post_meta($product_id, 'sample_price', true) ? get_post_meta($product_id, 'sample_price', true) : 0;
if ($sample_price_mode === 'custom'){
$price = $sample_price;
}else if ($sample_price_mode === 'free'){
$price = 0;
}
$cart_item['data']->set_price( $price );
//$product_price=apply_filters( 'woocommerce_cart_item_price',$price, $cart_item, $cart_item_key );
}

$_product     = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
//custome RI code start

This example demonstrate how to make csv file form mysql table using php. in this example csv file will contain name, username and email from user table. database connection has been takem dynamically from joomla configuration.php file. you need to change it as your requirement.

<?php
    require_once "configuration.php";

    $config = new JConfig();
    $host = $config->host;
    $db = $config->db;
    $dbprefix = $config->dbprefix;
    $password = $config->password;
    $user = $config->user;

    $con = new mysqli($host,$user,$password, $db);


    $filename = "users.csv";
    $fp = fopen('php://output', 'w');
    $header = array("name","username","email");

        header('Content-type: application/csv');
        header('Content-Disposition: attachment; filename='.$filename);
        fputcsv($fp, $header);

    $query = "SELECT name, username, email FROM jnr6o_users";
    $result = $con->query($query);
    while($row = mysqli_fetch_row($result)) {
            fputcsv($fp, $row);
        }
exit;
