<p>I want the quantity selector value to change based on the weight we set in Shipping >Product Weight for a simple product. As shown in the image below, when we set the weight of the product to 0.5 kg, the product quantity selector starts from 0.5 and if we set it to 1 kg, it starts from 1. Finally when we set the weight to each number, the quantity selector should fire based on the weight number we defined. I modified the code but it doesn't work for values ​​less than 1. </p> <pre class="brush:php;toolbar:false;">/*Quantity Selector Based On Simple*/ function custom_quantity_selector_min_value( $min, $product ) { $weight = $product->get_weight(); if ( $weight > 0 ) { $min = $weight; } return $min; } add_filter( 'woocommerce_quantity_input_min', 'custom_quantity_selector_min_value', 10, 2 ); //Modify the quantity selector step value. function custom_quantity_selector_step( $step, $product ) { $weight = $product->get_weight(); if ( $weight > 0 ) { $step = $weight; } return $step; } add_filter( 'woocommerce_quantity_input_step', 'custom_quantity_selector_step', 10, 2 ); //Update the quantity selector value dynamically. function custom_quantity_selector_value( $input_value, $product ) { $weight = $product->get_weight(); if ( $weight > 0 ) { $input_value = $weight; } return $input_value; } add_filter( 'woocommerce_quantity_input_value', 'custom_quantity_selector_value', 10, 2 );</pre></p>

function cart_variation_quantity_input_args( $args, $product ){
    $product_weight = $product->get_weight();
    
    if( $product_weight > 0 ) {
        if ( ! is_cart()) {
