<p>我希望数量选择器值根据我们在“运输”>“产品重量”中为简单产品设置的重量进行更改。 如下图所示，当我们将产品的重量设置为0.5公斤时，产品数量选择器从0.5开始，如果我们设置为1公斤，则从1开始。最后当我们将重量设置为每个数字时，数量选择器应该根据我们定义的权重数字启动。 我修改了代码，但它不适用于小于 1 的值。</p> <pre class="brush:php;toolbar:false;">/*Quantity Selector Based On Simple*/ function custom_quantity_selector_min_value( $min, $product ) { $weight = $product-&gt;get_weight(); if ( $weight &gt; 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-&gt;get_weight(); if ( $weight &gt; 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-&gt;get_weight(); if ( $weight &gt; 0 ) { $input_value = $weight; } return $input_value; } add_filter( 'woocommerce_quantity_input_value', 'custom_quantity_selector_value', 10, 2 );</pre></p>
