How to set a minimum quantity

Hi,
In the product ‘Unit Price’ settings set 10 in ‘Quantity Step’.
Copy the code from the plugin’s docs ‘How to set minimum quantity’ into your theme’s functions file, and update inside the code (instead of the other numbers):
’10’ => ’50’,
which means all the products which have ‘Quantity Step’ of 10 will have minimum quantity of 50.

Hi,
Thanks for your response.

I specified in Unit Price “0,10” and added this code into my theme’s functions file :

add_filter( 'upw_skip_args_validation', '__return_true' );
add_filter( 'upw_product_min_value', 'upw_set_min_value' );
add_filter( 'upw_variation_min_qty', 'upw_set_min_value' );
add_filter( 'woocommerce_update_cart_validation', 'upw_apply_min_quantity', 10, 4 );

function upw_set_min_value( $step ) {
	$min_values = [
		'0.10'	=> '0.50',
		'0.10'	=> '0.50',
	];
	return isset( $min_values[ $step ] ) ? $min_values[ $step ] : $step;
}

function upw_apply_min_quantity( $passed, $cart_item_key, $values, $quantity ) {
	$min_values = [
		'0.10'	=> '0.50',
		'0.10'	=> '0.50',
	];
	$step = $values['data']->get_meta( '_upw_step' );
	if ( $step && isset( $min_values[ $step ] ) && $quantity < $min_values[ $step ] ) {
		wc_add_notice( __( 'A minimum order amount', 'woocommerce' ) . ' (' . $values['data']->get_name() . '): ' . $min_values[ $step ], 'error' );
		return false;
	}
	return $passed;
}

Unfortunately it does not work correctly, I’m sure I’m missing something ! Can you please help ?

Hi,
If the Quantity Step is ‘0,10’ the code should contain exactly the same (and not ‘0.10’).

Hi,
Nothing changed. Display price is not correct if I do not refresh the page, and from 0,7 next number is 0,799. See : https://netmove.fr/wordpress/produit/popeline-de-coton/

Thanks,

Hi,
Please redownload the plugin, then change the Quantity Step (both in option and in code) to 0.1 instead of 0.10.

Hi,
Thanks, all done ! Price is now correct, but I still have the same problem from 0,7 (next number is 7,99).

Hi,
The quantity buttons of your theme doesn’t fully support decimal quantity step.
You can replace them using this plugin.
Then redownload the Unit Price plugin and add this CSS (to hide the quantity buttons in mini cart):

.widget_shopping_cart_content .qib-button {
   display: none !important;
}

Hi,
Thanks it’s working !
