I am trying to change the link & text of the Add to Cart button on the archive page if the products is already in cart.
I only allow quantity one per product to be added.
But the default way of Woocommerce is to direct to the single page with the notice.
Instead I would like the user to either
See the text "View Cart" and direct the user to the cart
or
See the text "Added" and have no link whatsoever.
Thank you
To change the text, you need the codes below.
add_filter('woocommerce_product_add_to_cart_text', 'wc_product_add_to_cart_text', 10, 2 );
add_filter('woocommerce_product_single_add_to_cart_text', 'wc_product_add_to_cart_text', 10, 2 );
function wc_product_add_to_cart_text( $text, $product ){
$product_cart_id = WC()->cart->generate_cart_id( $product->get_id() );
$in_cart = WC()->cart->find_product_in_cart( $product_cart_id );
if ( $in_cart ) {
$text = "View Cart";
}
return $text;
}
To redirect to cart, this will do it.
add_action( 'wp_loaded', 'wc_add_to_cart_action', 19 );
function wc_add_to_cart_action(){
if ( empty( $_REQUEST['add-to-cart'] ) || ! is_numeric( $_REQUEST['add-to-cart'] ) ) {
return;
}
$product_id = absint( $_REQUEST['add-to-cart'] );
$adding_to_cart = wc_get_product( $product_id );
$product_cart_id = WC()->cart->generate_cart_id( $product_id );
$in_cart = WC()->cart->find_product_in_cart( $product_cart_id );
if ( $in_cart && $adding_to_cart->is_sold_individually() ) {
wp_safe_redirect( wc_get_cart_url() );
exit;
}
}
or use this for the second part.
add_action( 'woocommerce_simple_add_to_cart', 'wc_simple_add_to_cart' );
function wc_simple_add_to_cart(){
global $product;
$product_cart_id = WC()->cart->generate_cart_id( $product->get_id() );
$in_cart = WC()->cart->find_product_in_cart( $product_cart_id );
if ( $in_cart ) {
remove_action( 'woocommerce_simple_add_to_cart', 'woocommerce_simple_add_to_cart', 30 );
echo sprintf( '<form class="cart">%s</form>', wc_get_cart_url(), __( 'View Cart', 'woocommerce' ) );
}
}
update
for shop page you need this code:
add_filter('woocommerce_product_add_to_cart_url', 'wc_product_add_to_cart_url', 10, 2 );
function wc_product_add_to_cart_url( $url, $product ){
$product_cart_id = WC()->cart->generate_cart_id( $product->get_id() );
$in_cart = WC()->cart->find_product_in_cart( $product_cart_id );
if ( $in_cart && is_shop() ) {
$url = wc_get_cart_url();
}
return $url;
}

I'm trying to add a custom field on each product on cart. I got the code from
WooCommerce: Add input field to every item in cart
but the update is not working. I tried to change the global $woocommerce to WC() but still it gives me 500 (Internal Server Error) on chrome console everytime I click update. heres the code:
cart.php:
<td class="product-url">
<?php
$html = sprintf( '<div class="url"><input type="text" name="cart[%s][url]" value="%s" size="4" title="Url" class="input-text url text" /></div>', $cart_item_key, esc_attr( $values['url'] ) );
echo $html;
?>
function.php (This is not a snippet so do not run):
// get from session your URL variable and add it to item
add_filter('woocommerce_get_cart_item_from_session', 'cart_item_from_session', 99, 3);
function cart_item_from_session( $data, $values, $key ) {
$data['url'] = isset( $values['url'] ) ? $values['url'] : '';
return $data;
}
// this one does the same as woocommerce_update_cart_action() in plugins\woocommerce\woocommerce-functions.php
// but with your URL variable
// this might not be the best way but it works
add_action( 'init', 'update_cart_action', 9);
function update_cart_action() {
global $woocommerce;
if ( ( ! empty( $_POST['update_cart'] ) || ! empty( $_POST['proceed'] ) ) && $woocommerce->verify_nonce('cart')) {
$cart_totals = isset( $_POST['cart'] ) ? $_POST['cart'] : '';
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
if ( isset( $cart_totals[ $cart_item_key ]['url'] ) ) {
$woocommerce->cart->cart_contents[ $cart_item_key ]['url'] = $cart_totals[ $cart_item_key ]['url'];
}
}
}
}
}
// this is in Order summary. It show Url variable under product name. Same place where Variations are shown.
add_filter( 'woocommerce_get_item_data', 'item_data', 10, 2 );
function item_data( $data, $cart_item ) {
if ( isset( $cart_item['url'] ) ) {
$data['url'] = array('name' => 'Url', 'value' => $cart_item['url']);
}
return $data;
}
// this adds Url as meta in Order for item
add_action ('woocommerce_add_order_item_meta', 'add_item_meta', 10, 2);
function add_item_meta( $item_id, $values ) {
woocommerce_add_order_item_meta( $item_id, 'Url', $values['url'] );
