how to get particular product quantity from the cart page in the woocommerce

With this code:

foreach ( WC()->cart->get_cart() as $cart_item ) {  
   $quantity =  $cart_item['quantity'];
   echo $quantity;
}

I can get the quantity of all the products added in cart but I need it for the particular product.

Answer

You can loop through cart items to get the quantity for a specific product id as follows:

// Set here your product ID (or variation ID)
$targeted_id = 24;

// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) { 
    if( in_array( $targeted_id, array($cart_item['product_id'], $cart_item['variation_id']) ){
        $quantity =  $cart_item['quantity'];
        break; // stop the loop if product is found
    }
}
// Displaying the quantity if targeted product is in cart
if( isset( $quantity ) && $quantity > 0 ) {
    printf( '<p>' . __("Quantity for Product ID %d is: %d") . '</p>, $targeted_id, $quantity );
}

Or you can also use the WC_Cart method get_cart_item_quantities() as follow:

// Set here your product ID (or variation ID)
$targeted_id = 24;

// Get quantities for each item in cart (array of product id / quantity pairs)
$quantities = WC()->cart->get_cart_item_quantities(); 

// Displaying the quantity if targeted product is in cart
if( isset($quantities[$targeted_id]) && $quantities[$targeted_id] > 0 ) {
    printf( '<p>' . __("Quantity for Product ID %d is: %d") . '</p>, $targeted_id, $quantities[$targeted_id] );
}

Note: This last way doesn’t allow to target the parent variable product.
