I'm trying to implement the following solution:
/*
* goes in theme functions.php or a custom plugin
**/
// add item to cart on visit
add_action( 'init', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
global $woocommerce;
$product_id = 64;
$found = false;
//check if product already in cart
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
$woocommerce->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
$woocommerce->cart->add_to_cart( $product_id );
}
}
}
from here:
http://docs.woothemes.com/document/automatically-add-product-to-cart-on-visit/
but it throws an error:
Sorry, this product cannot be purchased.
Anyone knows what am I doing wrong?
maybe your product stock quantity is zero or product is not there. Please check that.

I would like that anybody who visits my Woocommerce shop finds a free product in his cart. I found this code and it works but it shows many php errors in logs.
Do you have an idea why is not "clean"?
Any help on this please.
/*
* AUTOMATICALLY ADD A PRODUCT TO CART ON VISIT
*/
function aaptc_add_product_to_cart() {
if ( ! is_admin() ) {
$product_id = 99999; // Product Id of the free product which will get added to cart
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $product_id )

WC()->cart->add_to_cart( $product_id );
}
}
}
add_action( 'init', 'aaptc_add_product_to_cart' );
Try instead this revisited similar code using template_redirect action hook:
add_action( 'template_redirect', 'auto_add_product_to_cart' );
function auto_add_product_to_cart() {
if ( is_admin() ) return;
// Product Id of the free product which will get added to cart;
$product_id = 99999;
if ( WC()->cart->is_empty() )
{
// No products in cart, we add it
WC()->cart->add_to_cart( $product_id );
}
else
{
$found = false;
//check if product already in cart
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( $cart_item['data']->get_id() == $product_id )
$found = true;
}
// if the product is not in cart, we add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
}
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
Note: The init hook is not correct here and not to be used for this…
So I can use this snippet from the woocommerce docs and it works to add a free product when a cart total is reached. However, our customers need to be able to remove the product from the cart if they don't want it (repeat customers that don't want the same gift every time). With this snippet, the remove from cart button doesn't work for the free product.
/**
* Add another product depending on the cart total
*/
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
global $woocommerce;
$product_id = 2831; //replace with your product id
$found = false;
$cart_total = 30; //replace with your cart total needed to add above item
if( $woocommerce->cart->total >= $cart_total ) {
//check if product already in cart
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
$woocommerce->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
$woocommerce->cart->add_to_cart( $product_id );
}
}
}
}

code above is from here: https://docs.woocommerce.com/document/automatically-add-product-to-cart-on-visit/
Removing the product from the cart will actually work, but the problem is that the code will also automatically re-add the product again.
One way to solve this would be to remember that the product has already been added once, and to not re-add the product if the product would be added another time (after it has been removed from the cart for example).
A simple way to do that would be to save that data inside of the WooCommerce session, using WC()->session. Modified code below:
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
global $woocommerce;
$product_id = 2831; //replace with your product id
$found = false;
$cart_total = 10; //replace with your cart total needed to add above item
if( $woocommerce->cart->total >= $cart_total && ! WC()->session->get( 'free_item_given', false ) ) { // <--- ADDED CHECK FOR free_item_given HERE
//check if product already in cart
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found ) {
$woocommerce->cart->add_to_cart( $product_id );
WC()->session->set( 'free_item_given', true ); // <--- REMEMBER free_item_given HERE
}
} else {
// if no products in cart, add it
$woocommerce->cart->add_to_cart( $product_id );
WC()->session->set( 'free_item_given', true ); // <--- REMEMBER free_item_given HERE
}
}
}
}
I hope that it solves your problem!

I am aware that there's already an existing function where you can add a certain product on cart upon visiting the website. The problem is you can only do it with 1 product and I want it variable depending on the page you are visiting.
here's the existing code (added on functions.php file)
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
$product_id = 275;
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}
Inside my landing page called page-template.php, there's a custom field that echos the ID of a certain product selected. So when my user visits this page, I want this ID to replace the $product_id on the functions.php file. How do I achieve this?
Many thanks in advance for the help.
maybe the global variable is loaded after the function. instead of just setting the variable initiate the function passing the variable and avoid the hook:
in functions.php:
function add_product_to_cart($product_id) {
if ( ! is_admin() ) {
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}
in page-template.php:
add_product_to_cart(275);
I am working on a webshop test case and what I would like is to add automatically items/products to the cart on visit. So I searched for something like that when I found the same code over and over everywhere.
/*
* goes in theme functions.php or a custom plugin
**/
// add item to cart on visit
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
$product_id = 64;
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}

So this works fine if you have only one product but I would like to add more than just 1 product. Is there someone with some PHP knowledge (and a some WordPress) that can help me out? Thanks in advance!
There are actually two ways you can do this, at least. You can either call the add_to_cart function more than once, or create a loop. Both ways are down here:
Method 1
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
$product_id = 64;
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
WC()->cart->add_to_cart( $product_id2 );
WC()->cart->add_to_cart( $product_id3 );
WC()->cart->add_to_cart( $product_id4 );
}
}
}
Method 2
foreach ($articles as $article) {
WC()->cart->add_to_cart( $article );
}
Do note that you should create a new array called articles holding all the IDs from the desired products. Another thing that is going to bother you then is checking whether the cart holds more than 0 items, and checking if all of them are in there.
Method 2 would look something like this:
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
$articles = array(64);
$found = false;
// check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if (($key = array_search($_product->id, $articles)) !== false)
unset($articles[$key]);
}
// if product not found, add it
if ( count($articles) > 0 ) {
foreach ($articles as $article) {
WC()->cart->add_to_cart($article);
}
}
} else {
// if no products in cart, add it
foreach ($articles as $article) {
WC()->cart->add_to_cart( $article );
}
}
}
}
